Abstract: 550,553. Window operating mechanism. TRICO PRODUCTS CORPORATION. Sept. 19, 1941, No. 12073. Convention date, Dec. 18, 1940. [Class 20 (iii)] Mechanism for the fluid actuation of vehicle windows comprises a cylinder 9 enclosing a composite piston, one part 12 of which is fixed to the rod 8 coupled to the window, and the other 13 connected to the rod through a lost motion arrangement 28, 15. Between the parts 12, 13 is a brake 17 mounted on a disc 19. Manual attempts to push in the rod 8, as in an attempt to force open the window are frustrated by the brake 17, which however is dragged idly along the cylinder wall during fluid-pressure or suction action. Sub-atmospheric pressure is maintained in the cylinder by connections to the induction pipe except when one side or the other is opened to the atmosphere, thus effecting window adjustment. The outside air is prevented from entering the cylinder by a washer the cupped portion 30 of which surrounds the shaft 8 within a recess in the bearing 11. Its action may be supplemented at the end positions of piston travel by cupped washers fixed to the rod and bearing against one or the other side of the cylinder closure 10. A light spring may surround the cupped portion 30 to increase its adhesion to the shaft. In closing the window by manual action accompanied by withdrawal of the rod 8 from the cylinder, fluid in advance of the piston face 12 is vented through the valve 30.

Abstract: 1399351 Measuring angular velocity; voltage measuring ASSOCIATED ENG Ltd 24 Nov 1972 [2 Dec 1971] 55902/71 Heading G1N and G1U [Also in Division G3]  The phase angle of the profile of a cam member mounted on a rotating shaft is automatically adjusted in accordance with the speed of rotation of the shaft through either a follow-up switch arrangement or a balanced potentiometric arrangement. In a first embodiment Fig.1, a cam member 15 rotatable on a shaft 5 is angularly positioned by radial and angular displacement of a disc 9 having radial slots 10, 11 which engage pins 8a, 15a of a collar 8 pinned to the shaft 5 and the cam 15 respectively. The speed of rotation of shaft 5 determines the position of the fingers 38 of fly weights 36, and hence the position of axially movable member 39 and the transverse position of radially movable member 44, carrying microswitches 50; 51 which are normally both open but are selectively closed when member 44 is  displaced by a rack member 45. Closure of switch 50 or 51 energizes a motor 34 to reposition rack 45 via gear 49 until both switches are again open, simultaneously rotating shaft 33 and an eccentric 31 to produce the required radial and angular movement of disc 9 and corresponding phase shift of cam 15. In a second embodiment Fig.2, rotating shaft 65 produces a pulse train in coil 66 whose frequency is converted at 68 to a voltage proportional to the angular velocity. This is compared at 70 with a voltage from potentiometer 72 representing the angular position of shaft 33, and any difference is used to stop motor 34 in the appropriate direction to reposition slider 71 and balance the two inputs to comparator 70. The field winding 62 of D.C. motor 34 is additionally fed with pulse trains of equal frequency by generators 75, 77, each feeding one half of the field winding 62. Any difference between the two inputs to comparator 70 causes the frequency of one pulse train to rise and stop motor 34 in the appropriate direction until the two inputs are equal. The angular position of cam 15 may be positioned in accordance with another parameter e.g. engine torque, or a combination of speed and torque.
