Abstract:
151,289. Morris, R. Sept. 19, 1919, [Convention date]. Sliding sashes removable from frame; sash-cord attachments.-The meeting edges of the sashes and frame are bevelled at 8, 9, 10, 11, 13, 14, 15 to exclude draughts &c. The lower section of the inside bead is hinged and that of the parting-strip is removable to allow the windows to be removed from the frame. The meeting edges of the sections of the parting-bead are bevelled and protected by metal plates in which a sliding bolt works to fasten the sections together. Lateral ribs 20 on the parting-strip engage grooves in the upright sash members which terminate in the meeting rails. The meeting rails have complementary cut-away portions to take the parting- bead and conceal the junction in its sections when the windows are closed. To permit vetilation, the lower sash can be inclined inwardly, Fig. 2, and secured by a link 29 pivoted in a metal-protected recess in the fixed portion of the inside bead and engaging a pin in the sash. A triangular shield 35 is provided for each side when the window is thus opened, one edge of which is clipped to the rib on the parting-bead and another edge engaged with upright sash groove. The pin 30 on which is pivoted the link 29 also carries a small pulley for the sash-cord and a turnbutton fastener 32 for the hinged section of the inside bead. The sash cord is secured by a knot in a groove of Z-shape 38, 39, covered by a slotted plate held by the screw-heads 40, and is provided with a ring by which it may be secured to a hook on the frame when the window is removed. Two catches 17 are provided to secure the sashes together tightly at the meeting rails.

168,596. Norris, R. Sept. 2, 1920, [Convention date]. Frame pulleys.-Comprises a frame pulley for supporting and guiding the sash cords of windows. A framework is pressed from a single sheet of metal to provide a curved main portion 1 and horizontal and vertical flanges 5, 2 respectively, and is mounted between the window framing and the walls so that the vertical flanges engage, and are fixed to, the side post B and the horizontal flanges are fixed to the top bar A. The curved portion carries two pulleys 13, one of which is mounted in alignment with the axis of the post B while the other is in alignment with the axis of the bar A. The cord 9 passes from the sash through a, metal guide thimble 8, and round both pulleys to the balance weight 10.

239,774. Wickham & Norris, Ltd., and Morris, F. R. Feb. 9, 1925. Couplings for tractors.-Relates to a two-wheel trailer comprising a frame mounted on a wheel axle and having a draw-bar connected to the axle and to a shoe at the front of the frame so that the tractive force is exerted on the axle alone. A trailer of this kind is described in Specification 239,332. According to the invention, the drawbar e instead of being slidably adjustable as described in the above mentioned Specification, is hinged at h to the axle c so that when a pivoted front leg l is lowered to the ground and the trailer is backed, the frame a, b can turn about the hinge to raise the shoe for facilitating coupling and uncoupling the tractor and trailer. The, frame members a are provided with fixed extensions : i carrying the shoe j which embraces the draw-bar e and supports it by means of a pin k. The draw-bar is provided with a shock absorbing attachment f, g for connection to the tractor. When the pin k is removed and the leg l lowered, backing the trailer will disengage the shoa from the draw-bar.
Abstract:
Apparatus for harvesting required crop parts from standing crop, leaving stripped stems in the field, comprises a crop stripping rotor (11) under a hood (18). Grain particules strike the underside of the hood (18), and four or more piezo-electric impact detectors (23, 24, 25 and 26) detect the pattern of grain strike density along the hood. Front end grain losses are found to be related to the pattern of grain strikes on the underside of the hood. The hood position is adjusted by a ram (14) in response to data measured by the detectors (23, 24, 25 and 26).
Abstract:
Apparatus for harvesting required crop parts from standing crop, leaving stripped stems in the field, comprises a crop stripping rotor (11) under a hood (18). A plurality of outwardly projecting crop stripping elements (15) are mounted on the rotor and move upwardly and rearwardly as the apparatus moves forwardly into the crop. The distal tips of the elements (15) enter the crop and move upwardly through the crop, gathering one or more crop stems. Between adjacent crop stripping elements (15) two succeeding relief regions (21A) and (21B) are provided. Gathered crop enters the first relief region (21A) and required parts are stripped by edges (20) of the relief region. Stripped stems pass to the second relief region (21B) for easy release and in order to avoid rejecting unstripped stems from the first relief region (21A).
Abstract:
A retainer resists decoupling of a first connector of a first cord from a second connector of a second cord. The retainer includes a first receiver having an adjuster to adjust the receiver about a portion of the first cord. The retainer includes a second receiver having an adjuster to adjust the receiver about a portion of the second cord. A connector housing couples the first and second receiver. The first receiver, second receiver, and connector housing form a continuous chamber in which lies portion of the first and second cords connected together when the retainer resides in an installed orientation. The retainer, in the installed orientation, resists incursion of water, dust particulate matter and other debris into the continuous chamber.
Abstract:
An autonomous vehicle and systems having an interface for payloads that allows integration of various payloads with relative ease. There is a vehicle control system for controlling an autonomous vehicle, receiving data, and transmitting a control signal on at least one network. A payload is adapted to detachably connect to the autonomous vehicle, the payload comprising a network interface configured to receive the control signal from the vehicle control system over the at least one network. The vehicle control system may encapsulate payload data and transmit the payload data over the at least one network, including Ethernet or CAN networks. The payload may be a laser scanner, a radio, a chemical detection system, or a Global Positioning System unit.
Abstract:
A steering control method including the steps of obtaining a heading error, obtaining a velocity value, obtaining a distance error, applying the heading error and defuzzifying an output from a steering rule base. The velocity value and the distance error are applied along with the heading error to fuzzy logic membership functions to produce an output that is applied to a steering rule base. An output from the steering rule base is defuzzified to produce a steering signal.
