Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1920-06-24
Abstract: 168,714. Westinghouse Brake & Saxby Signal Co., Ltd., and Rendell, A. W. June 24, 1920. Fluid-pressure.-To prevent overcharging of the trainpipe and auxiliary reservoirs of a fluid-pressure brake system, the train-pipe is connected to a source of pressure normally maintained at the normal train-pipe pressure, instead of directly to the main reservoir, in releasing the brakes. As shown in Fig. 2, a supplementary reservoir 9 is connected to the main reservoir 1 through a reducing-valve 3 whereby it is supplied with air at the normal train-pipe pressure. In releasing the' brakes the reservoir 9 is connected directly to the train-pipe 7 by the pipes 4, 8, and driver's valve 5, the main reservoir being connected. through the reducing-valve 3. In running conditions, the reservoir 1 is connected to the train-pipe through the pipe 13 and reducing-valve 14. In a modification, the pipe 13 and valve 14 are dispensed with, the pipe 4 being connected to the train-pipe in running as well as release but through a smaller port in the driver's valve.

When the photocell signal is above a predetermined level, indicating an on-coming high beam, relay 157 is energized, contacts 174 and 172 are closed and open respectively and operation of a foot switch 155 applies a +12 volts to the cathode of triode 117 cutting it off for a period determined by resistor 120 and energizing a motor 148 to flash the lights. When the photo-cell signal is below the predetermined level contacts 174 and 172 are changed over. On closing switch 155, relay 173 is energized, lighting a lamp 186 which simulates an on-coming high beam and initiates anti-dazzle working.

Title: Improvements in control valves applicable to fluid-pressure operated vehicle brakes
IPC: B60T13/40
Filed: 1953-06-25
Abstract: 734,637. Fluid-actuated valves. BOSCH GES., R. June 25, 1953 [June 26, 1952], No. 17581/53. Class 135. [Also in Group XXXIV] A control valve, e.g. for a vehicle and trailer braking system, has a plurality of pressure chambers separated by walls through which extends a valve closing member, at least one of the walls is flexible and secured at its inner periphery to the member and has its outer periphery sealingly slidable on the chamber wall so that pressure on the inner part of the flexible wall operates constantly on the member while pressure on the outer part of the wall operates on the member only so long as its outer periphery is not resting against a stop preventing its sliding movement. A tube 4 is slidable sealingly through two elastic collars 11, 12 sealed at their edges to a cylinder 3 and spaced apart by a sleeve 13 so that the collar 12 abuts a disc 16 secured to the tube, and is secured through the, centre of an elastic diaphragm or wall 18 sealingly slidable in a larger cylinder 2. The periphery of the diaphragm 18 is backed by a rigid disc 19 slidable on the tube and loaded by a spring 29 and acting on the tube through a spring 23 and tube ring 22. When an initial low fluid-pressure is applied by the vehicle brake valve 36 to the brake cylinder 37, the pressure acts via pipe 34 on the whole area of the collar 18 so that it slides in its cylinder against the spring 29 and through the disc 19 and spring 23 shifts the end of the tube so that a valve 9 shuts on its seating 7 and the end of the tube moves away from the valve. Air pressure in the pipe 33 leading to the trailer brake valves and on one side of the collar 12 then escapes to atmosphere via the passage 6, tube 4 and a filter 28 so that the unbalanced pressure on the other side of the collar 12, supplied via pipes 30, 31 from the reservoir 32; reseats the end of the tube 4 on the valve 9. A further increase of pressure in the pipes 35, 34 and on the diaphragm 18 makes the disc 19 abut a casing shoulder 24 and the smaller central area of diaphragm 18 shifts the tube 4 away from the valve 9 again. Release of pressure from pipes 35, 34, allows the spring 29 to move the tube to the right and unseat the valve 9 to supply air pressure to pipe 33.

Title: Improvements in or relating to the detection and indication of the presence of inflammable vapours or gases
IPC: G01N25/36
Filed: 1936-06-25
Abstract: <PICT:0477338/III/1> <PICT:0477338/III/2> In apparatus for the detection and estimation of inflammable gases or vapours having a thermally-operated switch, e.g. a bi-metallic switch, designed to operate at a heating effect corresponding to a given percentage of combustible gas, the switch is automatically adjusted to compensate for oxygen deficiency or variations in the carbon dioxide content of the atmosphere.  For example, the thermal switch may be a bi-metallic diaphragm 1 arranged over the flame or burner 12, and operating a warning lamp 13.  Connection between the inner side of the diaphragm and the atmosphere is made via pipe 4, through a vessel 5 containing an absorbent for carbon dioxide, so that on increase in the carbon dioxide content, or decrease in oxygen, an increased vacuum is applied to the diaphragm bringing contacts 2 and 3 closer together, so that the switch will be operated by the less heat generated in an oxygen-deficient atmosphere when the predetermined content of combustible gas is attained.  Initial adjustments are made by adjusting the contact 3 by screw 11.  By applying a vacuum through branch pipe 8, the accuracy of the warning device may be tested.  In a modification shown in Fig. 2, one contact 22 is carried by a bi-metallic strip 21, the other contact being carried by a hollow diaphragm 24 which collapses as before bringing the contacts closer together.

Abstract: 1391194 Photo-copying apparatus HOECHST AG 20 April 1972 [22 April 1971 31 Jan 1972 (4)] 18305/72 Heading G2A Each original fed through a copier gives rise to a speed-determining signal before the preceding original has left the exposure zone, this signal is stored until the preceding original has left the exposure zone, and then the signal is used to control the speed of a motor 21 as it feeds the original and copy material through the exposure zone. Preferably the signals are obtained by measuring the translucency of successive originals. In the embodiment shown, as originals pass through the copier they trip switches S 2 , S 3 , S 4 , S 6 , S 7 , S 14 , S 15  to initiate the various steps of the process. As each original is fed in, the translucency of different areas thereof is measured using filters 9a-9e, 9a'-9e' photo-sensitive elements 8a-8e, 8a'-8e' and amplifiers 10a-10e, 10a'-10e'; and for each original the signal corresponding to the greatest translucency is selected by discriminators 11, 11'. The following sequence takes place: a first original passes photosensitive elements 8, the resulting signal is stored by a capacitor C 2 , a second original passes photosensitive elements 8' the resulting signal is stored by capacitor C 3 , the signal on C 2  is applied to a speed controller 19 of motor 21 and the first original is copied, the signal on C 1  is discharged, the first original is ejected at maximum speed, the signal on C3 is applied to controller 19, the second original is copied, C 2  is discharged, and the second original is ejected at maximum speed. Preferably light is conducted from the copying source to measure translucency (e.g. by mirrors, metal tubes, fibre optics). Lamps (L1-L3) Fig. 4 (not shown), are used to synchronize the different parts of the circuit.
