Abstract:
Portable water delivery apparatuses and methods of use are disclosed herein. An example apparatus includes a portable frame trailer having: a base; and at least two wheels, a tank configured to be transported on the portable frame trailer, a pump for delivering water in the tank to an interface, means for coupling the pump to a water input in a structure, and a portable power supply delivering power to the pump.
Abstract:
For use in MR imaging of a patient a plurality of surface electrodes such as ECG or defibrillator are provided for obtaining electrical signals for determining electrical activity within the body of the patient and remain in place during the MR imaging. The surface electrodes include a quick disconnect wire for carrying the signals to a signal processing system to be removed during the MR imaging to prevent heating. Each electrode comprises a conductive layer divided by slits into separate side by side sections to reduce eddy currents which are induced in the surface electrodes when they are exposed to variations in the magnetic field. The sections all are connected through the layer to the conductive location to allow the signal therefrom to be connected to the communication conductor.
Abstract:
A fluid storage and delivery apparatus may include a fluid container and a vent valve for releasing fluid from the fluid container. The vent valve may include a vent valve body formed from a single piece, and a vent valve inlet and vent valve outlet coupled to the single-piece vent valve body. The apparatus may also include one or more coupling members at least partially defining a fluid passageway between the vent valve and the fluid container.
Abstract:
A system and method for providing a remote alert from a clock radio to a user at a predetermined time without disturbing others around him. The clock radio is preferably a superheterodyne receiver and includes an alert signal circuit for providing radio frequency alert signals at a predetermined alarm time and a radio frequency transceiver for receiving broadcast radio frequency signals and for transmitting radio frequency signals including the broadcast radio frequency signals and the radio frequency alert signals. A timing circuit in the clock radio includes a coincidence detecting circuit which detects the coincidence between the time of day and the predetermined alarm time, and causes the alert signal circuit to provide an alert signal to the radio frequency transceiver for transmission to a selected wireless remote alert device at the predetermined time. The selected wireless remote alert device receives radio frequency signals at the predetermined time, including the radio frequency alert signals, and processes such received radio frequency signals in a manner similar to the superheterodyning technique. The thus processed signal will then be provided to a transducer in the wireless remote alert device, which will in turn produce a tone or a small vibration, or reproduce the broadcast AM or FM signal. The wireless remote alert device is preferably inserted in the user's ear, awakening only the user.
Abstract:
This mass flowmeter is designed to be installed in pipelines having nominal diameters greater than about 150 mm. It has a support tube (11), a vibrating system (12) disposed axially in the support tube and consisting of two straight measuring tubes (21, 22) mounted in a holder (23, 15) at each of their ends, and a vibration exciter (50) which sets each measuring tube into natural-resonance flexural vibration at the center. The soft-magnetic armature (51) of the vibration exciter (50) is secured to one of the measuring tubes, and its electromagnet (52) is mounted in the wall of the support tube (11) opposite the armature (51) via the metallic, nonferromagnetic coil can (53) and contains a soft-magnetic core (54). The central portion (55) of the latter, which is disposed in an energizing coil (57), carries a permanentmagnet inset (58) at the end opposite the armature, and the edge portions (56) of the core (54) extend along the outside of the energizing coil. Vibration sensors ( 30, 31) for sensing the mechanical vibrations are mounted on both sides of and at preferably equal distances from the vibration exciter (50), and an evaluation circuit (60) is provided for determining the mass rate of flow from the phase difference of the signals delivered by the vibration sensors. This results in a very high efficiency and a linear excitation-current dependence of the vibration exciter.
Abstract:
The invention relates to a tensioning device (15) for an endless transport belt (14), whereby the tensioning device (15) comprises two tensioning edges (16) around which the transport belt (14) is deflectable, and at least one spring section (26, 26′) integrally formed with the tensioning edges (16) and arranged between the two tensioning edges (16). This tensioning device (15) can be provided with a transport belt (14) and used in an automatic gripper system (1).
Abstract:
A method of making a microneedle array structure (20) comprising a plurality of simultaneously formed microneedles (24), each microneedle (24) having a protrusion (32) and a passageway (34) extending therethrough. The method comprises the steps of pressing an embossable sheet material between a complimentary tools and radiantly heating the sheet material using radiant energy from a radiant energy source. One tool is relatively-radiantly-transparent, and another tool and/or the sheet material is relatively-radiantly-absorptive.
Abstract:
A piston and a reciprocating expansion engine with a piston having a piston head, a piston neck, and a piston shaft are described. The piston head has at least one groove which runs in a circumferential direction suitable for receiving a piston ring, and the piston shaft has a pin boss and, at its outer circumference, a guide surface which is suitable for guiding the piston along a cylinder inner wall. An outer diameter of the piston neck is smaller than an outer diameter of the piston head and/or of the piston shaft, and the length of the piston neck approximately corresponds to the travel of the piston in the installed state.
Abstract:
The invention is related to a packaging arrangement, comprising a transport device for transporting products in a first position oriented in a production direction, and for selectively rotating the products into a different position relative to the production direction.
Abstract:
The disclosure relates to a packaging system comprising a product feeder and a packaging machine, wherein a monitoring unit, which is arranged upstream of or along the product feeder, detects at least one characteristic of the products and transmits it to the control unit. Depending on the category of the packed products, a downstream sorting station sorts the packagings into collecting containers provided for them or onto conveyor belts provided for them. The disclosure also relates to a corresponding method for operating a packaging system.
