Abstract: An electrical primer comprises a conductive pyrotechnical priming composition 3 placed in contact with a useful pyrotechnical charge 2 of the primer and two electrodes 6 and 7 in electrical contact with the conductive pyrotechnical composition 3. The resistance of conductive pyrotechnical priming compositions tends to vary with external conditions and time, so that primers employing such compositions tend to be of somewhat unpredictable performance. To alleviate this, a stable electrical resistance 10 is connected in parallel with the conductive pyrotechnical composition 3, between the two electrodes 6 and 7. The invention is applicable to the electrical ignition of pyrotechnical devices. <IMAGE>

Abstract: A castor retaining tube insert 10 comprises a body portion 12 configured for sliding insertion into an open end of a tubular strut, an end stop 14 and a castor spigot retaining bore 16. The body portion 12 has six elongate bearing surfaces 18, 20, 22, 24, 26 and 28 arranged in a double cruciform shape, each having ramp portions, for example 36 and 38, adjacent recesses, for example 40 and 42. As the tube insert 10 is pushed into an open end of a tubular strut, the ramp portions disposed at each end of the tube insert 10 provide resistance to insertion which can be overcome by forcing the tube insert 10 into the strut. This causes excess material to be sheared from the ramp portions which can collect in the recesses adjacent the ramp portions to lessen the likelihood of the tube insert 10 jamming in the strut. <IMAGE>

Abstract: A speed control device is provided for a motor vehicle allowing the driver to maintain the vehicle at constant speed while still remaining full control with his foot over the acceleration and deceleration of the vehicle. The path of a foot pedal is subdivided into two sections, where the first section corresponds to an acceleration of the motor vehicle and where the second section corresponds to a deceleration of the motor vehicle. A snap-in detention device is provided at the junction point of the two sections such that a foot can rest with a force slightly above the weight of the foot against the foot pedal while the speed of the motor vehicle is maintained constant. The foot pedal is connected to a piston, which in turn is supported by a relatively soft spring. The soft spring is supported by a second piston, which in turn is supported by a harder spring resting against a casing wall. The two pistons are connected to respective potentiometers via sliders and an acceleration control circuit compares the actual acceleration or deceleration with the settings of the potentiometers.

Abstract: The DC pulses produced by the generator have varying size dependent upon frequency and/or magnetisation, and are fed to a changeover switch in permanent connection with an energy storage unit and a load. A control circuit monitors the voltage occurring over the storage unit, and dependent upon it controls the transmission from the switch of pulses to the unit. The generator is a constantly magnetised type driven at varying speeds, thus providing varying AC voltage, and is coupled to a rectifier. The outputs from the rectifier are connected partly to the changeover switch, and partly to one input of the control circuit. The second input of the control circuit is connected to the switch output, and its output is in controlling contact with the switch. The output of the switch is connected to a capacitor comprising the energy storage unit. The control circuit partly monitors the voltage level over the capacitor and partly the fed half-wave zero passage so that when the voltage level drops below a specific value, the control circuit reacts and closes the switch. Thus a number of DC pulses are transmitted to the capacitor for storage so that full drive voltage is achieved. The control circuit then breaks the switch.

Abstract: A hydraulic device for controlling the knee-joint function in a leg prosthesis has a cylinder which is divided into first and a second cylinder parts adapted to be fixed to the lower leg of the prosthesis, and a piston rod which carries one piston in each cylinder part and is fixed to the upper leg of the prosthesis. The pistons divide the interior of the respective cylinder parts into two chambers. The adjacent first chambers of the cylinder parts are interconnected by a throttle device. The two, second chambers are also interconnected. One piston has a sealing member which is of a single-acting type to allow leakage of hydraulic fluid from the second chamber to the first chamber when the piston is moved in a direction reducing the volume of the second chamber, while it is completely sealing when the piston is moved in the opposite direction. A connection is provided between one of the first chambers and one of the second chambers. A pressure relief valve is arranged for opening this connection when the pressure of the hydraulic fluid in the one first chamber exceeds a predetermined value.
