Title: Apparatus for providing a load- and engine-speed-dependent gearshift operating pressure in motor vehicle transmissions
IPC: F16H61/00
Filed: 1974-05-03
Abstract: 1461838 Change-speed control ROBERT BOSCH GmbH 3 May 1974 [5 May 1973] 19436/74 Heading F2D Apparatus for providing a gear-shift operating pressure responsive to engine speed and load for effecting automatic shifts in a vehicle transmission comprises an engine driven pump discharging to a gear shift pressure line in which pressure is regulated by a valve spool controlling a spill passage, and means, e.g. a restriction, Venturi, &c., in the pump discharge line for producing a control pressure, the spool being acted upon by the gear shift pressure and by a balancing force derived in part from the position of the engine throttle and in part from the control pressure. In one embodiment, the engine driven pump 40, Fig. 1, discharges through a Venturi 41 to the gear shift operating pressure line 33, and a spill passage therefrom is controlled by an edge 15 of a main valve spool 12 subject on an annular surface 16 to the line pressure in opposition to a pressure responsive to throttle position acting on an annular surface 19 of a plunger 17 and to the control pressure transmitted through a passage 38 from the throat of the Venturi to a surface 18. The throttle pressure is controlled by a valve with a spool 23 loaded by a spring 25 which is adjusted by a cam 28 connected by Bowden cable to the engine throttle. In a modification, the cam 28 acts directly on the plunger 17, the valve spool 23 being dispensed with, and the control pressure is tapped from a curved portion of the line 33 instead of from the Venturi throat. In another modification the Venturi is replaced by an orifice plate the pressure upstream of which acts through a plunger and spring on the main valve spool in the same sense as the line pressure, and the pressure responsive to throttle position acts on the main spool in the opposite sense. Fig. 3 illustrates another embodiment, also using an orifice plate 61, in which a threedimensional cam 76, rotated by a Bowden cable connection with the engine throttle, is displaced axially by the pressure upstream of the orifice plate. The cam adjusts a spring 25 bearing on a valve spool 23 the output pressure from which acts through a connection 37 on one end of the main spool 52 in opposition to the pressure in the gearshift operating pressure line 33. The latter pressure is also effective in a line 72 controlled by a manual valve (not shown).

Title: Improvements in or relating to hoisting apparatus

Abstract: 749,123. Winch. DIDSBURY ENGINEER. ING CO., Ltd. Sept. 30, 1954 [July 14, 1953], No. 19439/53, Class 78 (5). A hoist comprises a shroud 30 permitting the accommodation of a single layer of cable upon the drum 16, and rotating with the drum, which drum is moved endwise upon rotation. As shown, winch drum 16 slides within shroud 30, the drum being rotated by crank handle applied at 15 or 47 and carrying captive nut 19 which reacts against fixed screw 18 to advance the drum relative to the shroud. Cable 25 is fixed in slot 26 formed in the drum and is led away from the drum to the load through tube 41 mounted in column 38. The latter is interchangeable to give different lengths and is provided with slots to allow for buckling of the rope. Governor 81 and free-wheel 100 and brake 60 serve to limit the speed of the descent of the load. To avoid backward rotation of the handle when the load descends under its own weight, the handle 89 (Fig. 5) is connected to shaft 47 by pawls 97 (not shown) and teeth 93, the teeth and pawls being normally separated by the action of spring 94 but, when the handle is rotated, the handle pivots at 91 and brings together the teeth and pawls to transmit the rotation to the drum. Alternatively, the connection of the handle may be by pin-and-slot.

[Also in Group XI] In a unitary microscope-support and lamp, including an optical system for projecting the light towards the microscope, a base is provided having a part on which the lamp is mounted and a part on which to mount the microscope, the said base being pivoted about a horizontal axis on a part of the support to enable lamp and microscope to be tilted without changing their relative positions. As shown, the support comprises a base 10 carrying a lamp house 12 and light directing housing 18 over the exit aperture of which a microscope may be clamped by fixed clamps 220 (one only is shown) and a clamp 194 adjustable in a slot 198 in the base 10. The base is pivoted at one end to a plate 32 having pegs 38 engaged by a bracket 42 pivoted to the base 10 to hold the latter in a desired tilted position. The lamp house 12 contains an iris diaphragm 158 the operating member 166 of which projects through the casing, a condenser lens 114 in a cylinder 116 axially movable by a rack 124 engaging a pinion 126 operated by a knob external to the casing, and an electric lamp 98. The latter is carried by a holder 76 attached to a spherical base 70 which is supported in a seating 68 in a member 64 rotatably supported by the housing and is pressed by a spring 80 against a screw 78. Attached to the ball 70 is a rod 72 pressed by a spring 82 against inclined adjusting screws 90, Fig. 6, projecting from the member 64. By adjustment of the screws 90 the lamp filament F may be moved in any direction transverse of the optical axis. Light from the lamp passes through the housing 18 and is directed upwards into the microscope by a mirror 178. Slots 172 are provided in the housing 18 to receive colour filters and a supplementary diverging condenser lens 184, Fig. 2, pivoted at 186 to the housing 18 may be swung into the illuminating beam.

Title: Detecting and recording of transient changes on a repetitive  electrical signal
IPC: G01R13/20
Filed: 1972-04-28
Abstract: 1386860 Detecting changes in repetitive signals CENTRAL ELECTRICITY GENERATING BOARD and C E FERNANDO 25 July 1973 [28 April 1972] 19933/72 Heading G1A Transient changes in a repetitive electrical signal are detected by displaying the signal on a CRO as a normally stationary waveform, applying the light to a photo-detector which produces an output responsive to the magnitude of the light output from each complete sweep, and detecting any change in the output of the detector, the detector being positioned and arranged so that it is non- uniformly sensitive to light from different parts of the CRO screen so that the intensity of the light at the detector depends on the beam position. The screen of the CRO is arranged so that it is viewed by a photo-detector provided with a tapered light guide both positioned above the screen so as not to obstruct the view of a recording camera. The position of the detector and light guide result in a non-uniform sensitivity to the light spot depending on its position on the screen. As shown, Fig.2, the detector comprises a photo-transistor 15 operated in an integrating mode. At the end of each sweep a pulser 22 applies a voltage to the photo-transistor and after a delay to allow the collector voltage to rise in response to the charge stored during the sweep the signal level is sampled by a gated amplifier 26. The resulting voltage is compared with that stored on a capacitor 31 by means of a comparator 32 to provide an output representing the change from the previous sweep. This output is compared with a D.C. level control by comparator 36 feeding a level sensor 34 to produce a trigger pulse to operate the camera shutter when a transient is detected. A diode pump 30 charges the capacitor to the voltage level corresponding to the last sweep so that changes between stable states or slow drifts are automatically followed. Potentiometer 36 may be motor driven to permit resetting when large changes in signal occur. If only an alarm signal is required or if the camera views a separate CRT the light guide feeding the detector may directly contact the screen. In this case light may reach the detector either directly or via reflections at the surface of the waveguide thus providing different detector sensitivities depending on the spot position.
