Abstract: A multiplexed analog to digital converter (10) receives analog signals from a plurality of sensors (18, 20, 22, 24, 26, 28) and continually delivers a sequence of digital signals to a microprocessor (30) over a single line. The microprocessor (30) accesses the digital signals independent of the converter (10) and determines the order in which the digital signals are received.

Abstract: Apparatus (34) for controlling an implement (12) supported on a machine (10), including means (36) for moving the implement (12) in response to sensed variables related to implement power, means (66) for sensing the longitudinal angular velocity of the machine (10) and means (60) for modifying the implement position in response to the sensed angular velocity of the machine (10). Earthmoving machines (10) and earthmoving implements (12) are difficult to operate to achieve maximum implement power and to control the implement (12) under changing working conditions. The apparatus (34) is designed to maximize implement power by automatically sensing and responding to variables related to implement power and to control the implement (12) by automatically sensing and responding to the longitudinal angular velocity of the implement (12).

Abstract: Extruded reinforced hoses are useful in fluid systems which operate at high pressures. Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space. Still other processes require extruding a hose on a mandrel and subsequently applying a fabric reinforcement member. In these processes, the length of the hose is limited by the length of the mandrel. The present apparatus produces an extruded reinforced hose (10) by braiding a metal reinforcement member (16) on a mandrel (42) and extruding a liner (21) and cover (22) at approximately the same location as the member (16) leaves the mandrel (42). The formed hose (10) is pulled at a linear rate faster than the hose (10) is being produced in order to change the braid angle of the braided member (16) to a predetermined selected braid angle and holding for subsequent curing. The metal braided reinforcement member (16) provides the high strength characteristic while the extruding of the liner (21) and the cover (22) at approximately the same location near the mandrel (42) eliminates the need for separate lengthy mandrels on which to extrude the hose (10), thus minimizing manufacturing floor space and reducing costs.

Abstract: An apparatus and method for continuously extruding an elastomeric hose (10) having a controlled internal size. A controlled internal size is necessary in order to mount various types of couplings to the hose. Other hose making processes require extruding the hose on a mandrel in order to control the internal size. The use of mandrels restricts hose length and requires additional floor space due to the lengthy mandrels. An extruded hose (10) having a controlled internal size is continuously made by extruding an elastomeric material over a first end portion (104) of an internal shaping member (102) and continuously monitoring the flow of air between a gauge member (112) and the internal size of the hose (10). The rate of extrusion is controlled in response to the flow of air between the gauge member (112) and the internal size of the hose (10) changing from a predetermined range. The continuous monitoring of the internal size adjacent the internal shaping member and adjusting the rate of extrusion in response thereto produces a continuous hose with a controlled internal size without the use of long mandrels.

Abstract: A speed sensing apparatus (10) counts a predetermined number of gear teeth (18) on a gear (16) driven by a motor (8). The duration of time required to count the predetermined number of gear teeth (18) is compared to a timing signal of preselected duration. The comparison is used to make a determination as to whether the velocity of the gear is above or below a preselected velocity.

Abstract: To service an engine (10), it is frequently determined that a cylinder liner (12) and piston (18) must be replaced. It is difficult and time consuming to first install the liner (12) and then the piston (18) with the rings (20) and connecting rod (22). A pre-assembled unit (36) including the liner (12) and piston (18) may be installed on the engine according to a disclosed method. The unitary assembly simplifies steps at the service facility and, if desired, permits assembly of the unit (36) prior to shipment to the service facility to reduce shipping space and cost.

Abstract: A dual operating mode seal assembly (10) is provided wherein a frictional force maintains a seal ring (50) in a static sealing mode during dither movements of a member (16) being sealed to eliminate frictional and abrasive wear to the seal ring (50) and member (16). A load ring (52) provides a shear force upon deflection sufficient to overcome the frictional force at a predetermined slip point to cause the seal ring (50) to enter a dynamic sealing mode in response to extended travel movements of the member (16).

Abstract: An electronic sensor (18) for determining motion of a moveable element (24) has a plunger element (14) for accurately positioning the sensor (18) at a preselected distance from the moveable element (24) in response to contact with the moveable element (24). A holding means (16) maintains the plunger element (14) at the desired position. Heretofore, similar sensing systems have employed the use of customized sensor bodies or manually inserted shims to establish the sensing system at its required location.

Abstract: A signal valve (38) is connected to a supply conduit (16) connecting a pump (11) with a control valve (14) for transmitting an artificial load signal to a load signal chamber (34) of a pressure compensated unloader valve (27) when the control valve is at an operating position and the pressure in the supply conduit (16) is below a preselected value. This moves a valve member (31) of the unloader valve (27) to a blocking position causing essentially full pump flow to be directed to the hydraulic jack for decreasing the response time in situations wherein the hydraulic jack has cavitated and no positive load pressure signal is present.

Abstract: A control mechanism (14) associated with a tractor operators seat (110) and an arm rest (112) which includes a steering selector apparatus (116) having an upstanding member (134) and a tiller arm (118) extending outwardly therefrom. The tiller arm (118) is advantageously located immediately forwardly of the arm rest (112) and has a mounting portion (142) and hand grip portion (144) that can be easily grasped by an operator's downwardly facing hand palm. A support assembly (136) pivotally supports the upstanding member (134) for movement about a fixed upstanding axis (140) and a control device (46, 50, 52, 54, 184) steers the tractor in response to the swinging movement of the tiller arm (118). In response to rotation of the hand grip portion (144) about the axis (158) of the tiller arm (118) a second control device (38, 42, 174) effects a change in the gear condition of an associated transmission (36).
