Title: Improvements in or relating to driving units, particularly for conveyors
IPC: H02K7/10
Filed: 1947-07-28
Abstract: 639,601. Conveyers ; winding and paying-out apparatus. CARTER, WILKINSON, Ltd., and WILKINSON, H. A. July 28, 1947, No. 20339. [Classes 78 (i) and 78 (v)] A driving unit of the kind having the driving means contained wholly within the driving drum or like member rotatable about a fixed shaft wherein a rotary support within the drum is rotatable about the longitudinal axis of the shaft and a motor and counterpoise are mounted on the rotary support on opposite sides of the fixed shaft and the reduction gearing is operatively connected to the drum and to the motor shaft. As shown, the driving unit comprises a fixed shaft 10 and a drum 12 journalled on the shaft. A support 46 having bearings 58, 60 on the shaft carries four electric motors 36, 37, 38, 39 each armature of which 40, 41, 42, 43 is connected to reduction gearing. The stators of the motors are positioned in radial arms 48, 50 of the support by straps 52 secured by clamps to the arms so that the motors are readily removable. Each shaft of the motors extends into a gear box 63. The reduction gearing of the epicyclic type comprises two sun wheels 66, 68 connected to the shaft and end plate 18 of the drum, respectively, and meshing with planet wheels 70, 72 which are interconnected and are keyed on one of the motor shafts. The numter of teeth in the two wheels differ by the same number in the sun and planet wheels. The current is supplied by a cable 78 through slip ring gear 74 connected by bushes 75 and slip rings to the motors. The gear comprises a disc 80 fixed on the shaft carrying brush holders 82. Two motors instead of four may be used and planetary grooved pulleys geared with the grooved sun wheels by endless belts.

Title: Control mechanism for regulating the thrust of rocket engines
IPC: F02K9/80
Filed: 1960-06-09
Abstract: 906,622. Jet propulsion nozzles. BENDIX CORPORATION. June 9, 1960 [June 11, 1959], No. 20345/60. Class 110 (3). [Also in Group XXXIII] The aft end 24 of a rocket casing 18 is formed with an internal annular restriction 26, and a disc-shaped member 30 has a flanged edge 32 defining with restriction 26 an annular throat 34 and nozzle 36. A central rod 38 secured to the forward end of casing 18, and steadied by radial rods 40, supports a control unit 45 comprising a housing 46 with a wall 62 fitting within a cylinder 63 to define a chamber 66. Chamber 66 is connectable through passage 65 with a source of fluid under pressure or a reservoir (not shown), to move chamber 66 and member 30 axially of casing 18 to vary the effective area of throat 34. The axial position of the chamber is sensed by an arm 74 and transmitted to a control 72. The thrust may be held constant by keeping the product of throat area and pressure within casing 18 constant, the pressure within casing 18 being proportional to that within chamber 66. The restriction 126 and flange 32 may co-operate as shown, so that the throat area increases as member 30 moves axially outwards of the casing, or may be shaped so that the throat area increases as member 30 moves axially inwards. Member 30 is also displaceable radially (see Group XXXIII), for which purpose small holes are formed in end wall 68 of chamber 66, the fluid leaking therethrough lubricating movement between member 30 and wall 68.

Masking plates 8 of lead are provided for attachment to the framework 1 at the rear of the exposure aperture 3 to produce 6, 4 or only 1 exposures in the shapes shown in Fig. 6 on a film in the cassette. To locate the cassette holder in the desired exposure positions a tongue 13 on the carriage 6 attached to endless chain 16 driven by motor 18 propels the carriage to the right as shown until the tongue 13 engages one of the stops A, B, D, C, which are of shapes shown in Figs. 2-5, on a sleeve 9 until the sleeve and hence the tongue 13 and the carriage are stopped by engagement of the end of the sleeve with an end stop 12, switches S20, S27 and S21, S25 controlling the speed of the motor during this operation; the operating stop being selected by rotation of the sleeve 9 from selector knob 36 secured to a rod 11 on which the sleeve 9 slides. A second motor 19 may be used to rotate the rod 11, and sequences of operations using the several stops are described.
