Title: Seat belt tension reliever with deceleration responsive overdrive
Inventor: HAMAUE TETSUYA
IPC: B60R22/44
Filed: 1990-11-09
Abstract: A seat belt system comprises a seat belt retractor 1 having a tensionless function to prevent take up of a seat belt, by allowing the wearer to take out a limited amount of slack, the belt then being held in this condition. An acceleration sensor is provided - see figs 6A and 6B, for sensing only a negative acceleration in the direction in which a vehicle is advanced, and a mechanism 17 for cancelling the tensionless function of the retractor in accordance with a signal received from the sensor. The sensor comprises a pendulum switch in which the pendulum 34 is spring biased to contact electrical contact 36 when no deceleration is occurring. When deceleration occurs, contact is broken against the force of spring 37, and the solenoid 17 (fig 1) is activated to disengage the tension relieving mechanism. The idea is that even under gentle braking, the passenger is reassured by feeling the belt tighten up. <IMAGE>

Patent GB-908584-A (GB)
IPC: G06M1/14
Abstract: 908,584. Counting-apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 15 1961 [May 19, 1960], No. 17719/60. Class 106(1). A counter in which rapid movement of the units wheel at transfer is obtained by means of a driving arm and a gravity arm mounted coaxially with the axis of rotation of the freely rotatable units wheel which carries stops for engagement with the arms is characterized in that the units wheel carries a bias weight adapted to stabilize the wheel subsequent to transfer. As described, the output shaft of an electricity meter drives through reduction gearing 9-13 and worm gearing 15, a drive shaft 17 on which are freely mounted the units wheel 4 and higher order wheels of a counter. The wheel 4 is in the form of a hollow drum on the outside of which is a stop 22 for engagement with a driving arm 18 attached to the drive shaft 17, and stops 23, 25 of lower height than the stop 22 and adapted to co-operate with a gravity arm 20 freely mounted on the shaft 17 between the wheel 4 and arm 18. In operation, the driving arm 18 drives the wheel 4 by means of the pin 22, the gravity arm 20 being driven by the stop 25 until just before transfer (Fig. 6) when the arm 20 falls through 180 degrees to a low position (Fig. 3) and drives the wheel 4 rapidly by means of the stop 23 from " 9 " to "0." In this position a bias weight 24 fixed inside the wheel 4 slightly over-compensates the effect of the weight of the stops 22 and stabilizes the wheel 4 to prevent oscillation about the zero registration position. The stabilization is at first assisted by a radial limb 19 on the driving arm 18, which limb co-operates with the stop 22 to prevent clockwise recession of the wheel 4. The wheel 4 remains stationary until the lost motion is made up and the arm 18 again contacts the stop 22. To keep the mechanical load on the driving arm low, the moment due to the gravity arm is greater than the combined moments of the driving arm and bias weight. Specification 908,585 is referred to.

Patent GB-2256676-A (GB)
Title: Active control of noise
Inventor: MOODY MARTIN JOHN
IPC: F01N1/06
Filed: 1992-07-10
Abstract: The control of noise emanating from engines and their exhaust systems is a difficult problem to overcome in a cost effective way. The noise may be reduced by the introduction of a fluid into the exhaust system such that the fluid is heated and expands rapidly producing sound and vibration which is in antiphase to the noise and vibration produced by the engine acting through the exhaust. There is a consequent reduction in the sound and vibration produced by the system. The fluid introduced is conveniently a liquid (water) which enhances the damping effect by virtue of possessing a latent heat of vaporisation. The fluid can be added to the exhaust system by a bleed from a turbo charger or super charger or by alternate means. A primary use would be for the reduction of engine noise emanating from exhaust systems in heavy goods vehicles.
