Title: Improvements in and relating to Wedge Type Actuators for Vehicle Brakes
Inventor: HILL ALBERT CHARLES
IPC: F16D65/22
Filed: 1965-06-09
Abstract: 1,151,352. Brake actuators. GIRLING Ltd. 27 May, 1966 [9 June, 1965; 8 July, 1965], Nos. 24334/65 and 28911/65. Heading F2E. In a wedge brake actuator comprising a pair of thrust members 120, 122 in opposed bores of a housing 112, a plunger 124 intermediate and movable transverse to the thrust members, a wedge member 156 carried by and slidably movable transverse to the plunger axis, and rollers 146 interposed co-operating inclined faces on the thrust and wedge members, a cage 136 carries the rollers and maintains their axes parallel and in a plane perpendicular to the plunger axis, a mechanical connection being provided between the cage and wedge member to restrict relative movement therebetween wholly to movement in a direction of plunger movement. The cage, which is W-shaped, and wedge member are located in a transverse bore in the plunger, which is actuated by a spring- loaded pull-rod 132. The cage is provided with rectangular apertures 139 in each of its arms 136 and a key 152 extends through the apertures to transverse channels in the plunger and has a projection 150 fitting in a groove in the wedge member. By virtue of the key and its engagement with the plunger and apertures 139, the cage is slidable relative to the plunger in a direction parallel to the plunger axis and in a direction parallel to the axes of the thrust members and the wedge member is constrained to sliding movement relative to the cage in a direction parallel to the plunger axis and perpendicular to the axes of the thrust members. Thus the rollers are always aligned with their axes maintained in a plane parallel to the axes of the thrust members, even if one of the thrust members become seized or deliberately fixed, Fig. 4 (not shown). In a modified embodiment, Figs. 6 and 7 (not shown), the key and wedge member form a unitary member 200, the upper end of the housing is closed by a cap having a bore constituting a guide for the upper end of the plunger.

Title: Improvements in or relating to cylinder paper-making machines
IPC: D21F9/04
Filed: 1936-10-24
Abstract: 472,098. Cylinder paper making machines. KODAK, Ltd. Oct. 24, 1936, No. 28995. Convention date, Oct. 26, 1935. [Class 96] In a method of making paper, the fibres of the paper stuff are laid on a making-wire passing round a cylinder immersed in the stuff by providing a pressure difference in the stuff outside the cylinder over the pressure in the liquid in the cylinder, undesired escape of paper stuff from the space between a dam, lying close to but spaced from the making wire, and the wire being prevented by maintaining a local pressure difference in the stuff at this place equal to the pressure difference on the making-wire at the place where fibre is being deposited. The stuff box 1 has a bottom wall 2, side walls 3 and end walls 4, 5, so formed that the upper surface 8 of the stuff in the chest may be raised above the cylinder in the box. A member 10 is provided to control the level of stuff in the box and the outlet 11 also permits the head to be maintained. Stuff enters at the inlet 12, passes around baffles 13, 14 and flows preferably in the same direction as the rotation of the cylinder to the outlet. The cylinder has hubs 17, spokes 18 and a rim 19. The hub 17 is hollow so that water may be drawn from the inside of the cylinder to keep the pressure there lower than outside the cylinder and cause the fibres to be rapidly laid on the making wire. Deckel straps 20 pass over guide rollers 21 through a water seal 22 into the stuff chest and pass along the flat edges or faces 23 of a dam member 24, and around the cylinder, lying on top of the making wire 16, and overlapping the edges of circular flanges 25 on the walls 3 of the chest to form a tight seal between the interior of drum 9 and the stuff chest. The dam 24 prevents escape of liquid between the wall of the stuff chest and the cylinder 9 where the wire 16 enters. This dam has a flange 34 bolted at 27 to a flange 35 on the top 15 of the stuff chest. It extends across the stuff chest from side to side, is hollow and has a flat slot or nozzle 28 which lies close to but out of contact with the wire 16. The spacing may be <1>/16". The opening inside the dam is connected with a pipe 31 leading to a vacuum pump 32. Thus, stuff tending to leak through space W is drawn away by the local pressure difference there. The nozzle 28 also draws white water through the wire 16 from the interior of drum 9 so that the wire is washed just before fresh fibres are deposited on it. This white water also dilutes the small amount of stuff leaking away at the space W and permits it to be carried away easily.

Title: Improvements in and relating to thermal starting switches suitable for electric discharge lamps
IPC: H05B41/06
Filed: 1945-11-02
Abstract: 603,867. Supply systems for discharge lamps. COLE, Ltd., E. K., and MOORE, F. J. Nov. 2, 1945, No. 29075. [Class 38 (iv)] [Also in Group XXXVII] A thermal starting switch for a discharge lamp, comprises normallyclosed contacts 1A, 2A, on similarly deflecting bimetal strips 1, 2, which carry the cathode preheating current, the contacts being opened on heating by a low-resistance heater 7 causing strip 2 to move towards the panel 8, so that contacts 1A, 2A disengage and 2A, 3A engage. If the lamp strikes, the voltage drop across the lamp applied to a subsidiary heating circuit consisting of parallel connected resistors 5, 6, is insufficient to cause strip 3 to move away from strip 2. If the lamp fails to strike, however, the full mains voltage is applied to the heaters 5, 6, and the latter, which has an inversevoltage characteristic, heats strip 3 rapidly and opens contacts 2A, 3A, allowing strip 2 to cool and contacts 1A, 2A to reclose. A lock-out device, consisting of a contact engaging a latch on a bimetal strip, may be provided. Alternatively, according to the Provisional Specification, a third resistance, in series with the two subsidiary heaters, may be provided so that the strip 1 is gradually heated, thereby causing contacts 1A, 2A, 3A, to engage and lock out the switch.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/38
Filed: 1919-11-24
Abstract: 146,920. Westinghouse, H. H. June 14, 1919, [Convention date]. Fluid-pressure.-In a brake of the kind in which a valve subject to brake cylinder pressure restricts the flow of fluid to the brake cylinder when a predetermined pressure has been reached therein, and the triple valve, when moved to application position, connects the train-pipe and the auxiliary reservoir to the brake cylinder, the valve for restricting the flow of fluid to the brake cylinder presents a smaller area to the brake cylinder pressure in one position than in another position for the purpose of obtaining a quick closing of the valve. The Figure shows the valve mechanism in the release position. Upon a reduction of pressure in the train-pipe 2 for an application of the brakes, the triple-valve piston 9 with the graduating valve 12 and the main valve 11 move to the right. Air then flows from the train-pipe 2 to the brake cylinder 3 through passage 8, check valve 31, passage 28, port 26 in the main slide-valve, cavity 30 in the graduating valve, port 27, passages 29 and 21, check valve 20, and passage 16. Air also nows from the auxiliary reservoir 4 to the brake cylinder 3 through valve chamber 10, port 25, passage 21 and check valve 20. When brake cylinder pressure acting in the chamber 15 upon a restricted area of the valve piston 14 is sufficient to overcome the spring 19, it moves the piston 14 from its seat and acts upon the full area of the piston 14. The valve 20 is thus allowed to close, and further flow of fluid to the brake cylinder can take place only through a restricted port 32.

Filed: 1961-08-16
Abstract: 918,344. Counters. BECKMAN INSTRUMENTS Inc. Aug. 16, 1961 [Aug. 25, 1960 (2)], No. 29502/61. Class 106 (1). A reversible decimal-coded binary cascade counter comprises feed-back means of two types for permuting the binary code in the forward and reverse directions, respectively. Control circuit 21 marks lead 20 or lead 30 for forward and reverse counting, respectively. Forward counting. Each input pulse reverses the first binary 10. The second pulse turns 10 off and causes R-C circuit 14 to apply a +ve pulse to AND gate 17 which also receives a +ve marking from lead 20 and a +ve marking from the right-hand output lead of binary 13 when it is off. Gate 17 then pulses binary 11 to turn it on. Ordinary cascade operation ensues until the eighth pulse turns binary 13 on and the ninth pulse also turns binary 10 on. Because binary 13 is on, AND gate 17 is now ineffective, but the left-hand output of binary 13 marks AND gate 24 which responds to the tenth pulse to effect forward carry and simultaneously turns 13 off so that the units counter is zeroized. Reverse counting. With all binaries initially off, the right-hand outputs are marked together with lead 30. Therefore the first input pulse turns 10 on and causes R-C circuit 31 to apply a +ve pulse to AND gate 35. Through the sequence of AND gates 35, 36, 37 binaries 11, 12, 13 are all turned on, but the left-hand output of 13 combines with the marking on lead 30 to operate AND gate 38 which, through rectifiers 39, 40, turns binaries 11, 12 off again. AND gate 38 also effects reverse carry to the next denomination.
