Title: Improvements in or relating to apparatus for indicating or signalling acceleration
IPC: G01P15/03
Filed: 1928-10-22
Abstract: 322,293. Wimperis, H. E. Oct. 22, 1928. Accelerometers.-An accelerometer for use on aircraft has means for giving to the pilot a tactile, visual or aural signal when a predetermined acceleration is reached. A control column has a handle 1 pivoted at 2 on a casing 3, which is fast in the upper end of a control column tube 4 beside which a cylindrical accelerometer weight 6, supported by a helical spring 7, is slidably mounted. The upper end of the accelerometer weight is designed in the form of two truncated cones 8, 9 surmounted by a thin stem 10. Bearing against the cone are two diametrically opposite rollers 11, 12, mounted in sliders 13, 14 which are engaged by toggles 15, 16, connected at their ends by links 17, 18. The link 17 is pivotally mounted at 19 on the casing 3, and the link 18 is engaged by a fork 20 extending rigidly from the handle 1. The toggles normally lie in a partly collapsed position, and are prevented from moving inwards by set screws 22. When the handle 1 is pulled in the direction of the arrow acceleration of the aircraft takes place in a vertical direction and the weight 6 moves downwards. When the aceeleration reaches a predetermined amount the rollers 11, 12 slip over the cone 9 and cause the collapse of the toggles 15, 16. The handle 1 will then jerk rearward giving an indication to the pilot that he has reached the maximum allowable acceleration. Upon moving the handle 1 forward again, the accelerometer weight rises in the control column tube and resets the toggles. Instead of the moving weight operating toggles it may operate by making and breaking electric contacts or by actuating pneumatic valves for controlling the signal device.

Abstract: 618,010. Resistances for strain-gauges. WALKER, P. B., TAYLOR, J., and COWLEY, W. L. Oct. 14, 1946, No. 30548. [Class 37] A strain-gauge element consists of one or more filaments 1 secured between two plates 4 and 5 of a substantially rigid elastic material, e.g. glass or metal, by casting or forming the material round it, or by placing it between two preformed plates which are subsequently secured to each other with a suitable adhesive such as a mixture of litharge and glycerine. The filament is initially protected by being held between thin sheets of paper 7 and 8, and if the plates 4 and 5 are themselves electrical conductors, the filament must be further insulated. The element can be calibrated prior to insulation in the position of use. The element can be used for measuring force directly, or it can be bolted to a structure for the measurement of strain or embedded in concrete.

Title: Improvements in or relating to weighing machines
Inventor: DAKER DEREK
IPC: G01G13/00
Filed: 1958-09-26
Abstract: 890,993. Weighing apparatus. BARRETT & SON. Ltd., W. S. Nov. 26, 1959 [Sept. 26, 1958], No. 30845/58. Class 143. In a weighing machine in which a goods container descends under load, is moved into a load discharging position and then returned to receive a new load, a photo-electric cell operates in response to the movement of a light-beam obliterator carried by the weighing machine so as to switch off an electric device during the descent, discharge and return of the container. As shown the container comprises a scoop 1 which is tiltable about an axle 4 carried by a support 2 which descends when the load exceeds the weight of counterweights carried by a like support (not shown). Extending laterally from the support is an arm 9 to which is pivotally attached at B a lever 11 comprising two arms A, C. The arm C carries at its end a flag 12 whose weight tends to turn the lever 11 about its pivot. When the scoop is in the position for receiving a load the free end of lever arm A contacts the base of the scoop as shown and lever arm C is held horizontal. When a load enters the scoop, the support 2 moves downwardly and flag 12 interrupts a beam of light 13 illuminating a photo-electric cell in control unit D. When the loaded scoop is tilted to discharge its contents, lever arm A is no longer restrained by the base of the scoop and as the support 2 rises flag 12 remains in a position obscuring the light until the scoop is reset to its load-receiving condition. The photo-cell is employed as a switch in the circuit of an electric motor driving feed means to the weighing apparatus, thus providing an automatic feed weigher which may be combined with the vegetable cleaning apparatus disclosed in Specification 848,556. The flag 12 is secured to the lever 11 by a bolt 18 in a vertical slot in a flange 16 of the flag, to allow for adjustment. The flag may alternatively be carried by the counterweight support, in which case the photo-cell switch is placed in series with a switch comprising contacts broken whenever the scoop is tilted to its discharge position.

Abstract: 871,072. Winches. AIR EQUIPEMENT. Oct. 7,1957 [Oct. 9, 1956], No. 31260/57. Class 78(5). An aircraft winch. drum on shaft 4 is driven by air motor 2 controlled by electric switches 63, 64. These switches control solenoid-operated air valves 58, 59, 69 which govern air valves 33, 34, the latter serving to supply air from pipe 30 to either pipe 35 or 36 so as to drive the rotor 6 of the motor 2 in one or other direction. Cock 31 controls the speed of the winch. Speed control.-When there is no load on the hook of the winch cable, the supply of air to motor 2 is cut down so that excessive speed of the hook shall not cause damage. This is effected through detector diaphragm 66 which detects the air pressure of (and therefore the load on) motor 2. When the pressure is low the diaphragm 66 operates switch 68 in the electrical circuit to operate slow-operation valve 69. The latter operates piston 42 of valve 32 but does so slowly, by reason of escape of air through jet 71, and thus opens merely tiny valve 72, allowing a part supply of air to the motor, so reducing its speed. Pistons 41, 42 are connected by lever 47 so that valves 33, 34 cannot be opened simultaneously.
