Title: Improvements in and relating to friction brakes
IPC: E05F11/00
Filed: 1919-07-22
Abstract: 154,651. Theyskens, A. July 22, 1919. Locking by frictional detents.-Relates to friction grips for use with sliding windows, doors, &c., such as described in Specification 24671/12, in which the movable member when forced to move by hand or otherwise causes brake shoes to be released or eased by the action of stops, the brake shoes automatically assuming their gripping position when the motion of the movable member ceases, and comprises a device having two brake shoes gripping the opposite edges of the sliding window &c., and forming the vertical sides of a pivoted parallelogram which is suspended on springs at one of its upper angles. In the form shown as applied to the window sash 1 of a railway carriage door, the brake shoes 2, 3 are linked together bv crossmembers 4 and suspended bv springs 5, 6, the spring 5 acting on a lever 7 pivoted at 8 and connected to the shoe 3 at 9, and the spring 6 acting on a lever 10 bearing under a pin 11 on the shoe 3. The parallelogram, being suspended from one corner, tends to become distorted, causing the shoes 2, 3 to hold the window sash frictionally. The weight of the shoe 2 may be counterbalanced partly by a spring 12. On pushing down the window sash, the parallelogram is moved with it for a short distance until the shoe 2 meets a stop 13, whereby the gripping-shoes are released. When the window is raised, the shoes are released by a stop 14 contacting with the upper end of the shoe 3. During the ascent the action of the spring 6 is cut off after a certain movement by the contact of the lever 10 against a pin 15. The brake shoes may be of U-section. Displacement of the parallelogram out of its own plane is prevented by short rods 20 having ball- and-socket connexions with the friction shoes 2, 3 and with the fixed frame 21 of the window. Fig. 4 shows a modification of the double-spring suspension means for the parallelogram, wherein the lever 10 is mounted on the same pivot 8 as the lever 7 and engages under an extension of the pivot 9 connecting the lever 7 with the shoe 3. To facilitate manipulation of the sliding window &c. in cases where powerful braking action is applied thereto, a device for releasing the shoes mav be provided as shown in Fig. 6, comprising a lever with two pins 24 engaging arms on the shoes 2, 3.

Title: Improvements in or relating to pulse filter circuits
Inventor: BARKER GEOFFREY CECIL
IPC: G01N27/48
Filed: 1957-06-13
Abstract: 820,244. Electric tests. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 28, 1958 [June 13, 1957], No. 18694/57. Class 37. [Also in Group XL (c)] In a derivative type pulse polaragraph the slowly changing D.C. level is removed from the pulse waveform by a circuit comprising a D.C. amplifier having a feed-back loop which is rendered inoperative during the pulses but maintains the D.C. voltage fed back substantially the same as that which would have been fed back in the absence of the pulse. A polaragraph cell PC having a dropping mercury electrode 2 is connected to the input of the amplifier and supplied with a polarizing voltage of the form shown in Fig. 1 (a). The resulting current through the cell comprises a desired component which occurs during the pulse and an undesired varying component which periodically returns to zero when a drop occurs. The cell is connected to an amplifier circuit V1, V2, V3 which provides an output at the cathode of V3 and also feeds a negative feedback path comprising amplifier valves V4 and V5, a switch V6, V7, V8, V9, a capacitor C1 and a Miller integrator circuit V11 which is connected to the input of valve V2. This feedback path which stabilizes the D.C. level is interrupted during the presence of the desired input pulses by applying positive and negative pulses A and B to the diode circuit. The capacitor C1 and the integrating circuit causes the current fed back to continue to change during the pulse at the same rate as immediately before the start of the pulse. It is stated that two circuits such as that shown may be cascaded if further stabilization of the D.C. component is required. The invention is applicable both to derivative type polaragraph and the normal type. The sharp current pulses occurring at the commencement of the desired pulse are eliminated if only the second half of the.pulse is utilized.

Abstract: 335,241. Carrier Engineering Co., Ltd., and Sainty, C. L. June 18, 1929. Gases, treating with liquids.-Gases are subjected in stages to treatment with liquids circulated by a pump at each stage to provide a spray which is formed at least in part by used liquid from the preceding stage so that substances which are soluble or miscible in the liquid are removed from the gas in progressive increments, the spray in any stage being of less concentration than the body of liquid in that stage. In one form a slightly inclined tunnel T is divided by liquid eliminating baffles 1 - - 6 into chambers C<1> - - C<7> each provided with sprays S from which liquid issues in the same or the opposite direction to the gas flow and supplied by pumps p from ponds P<1> - - P<7>. The liquid flows from pond to pond over weirs and partitions 1<a> - - 6<a> extending from the baffles ensure that liquid taken by the pumps includes that overflowing from the preceding pond. Liquid entering the system by a pipe 8 may first pass through a thermal control, e.g. a refrigerator to which outflowing liquid may be returned after passage through recovery apparatus. Incoming gas may pass through a heat exchanger 26: heat exchange may be effected with outgoing gas. Liquid from chambers C<1>, C<2> or from each chamber may be thermally conditioned and different substances removed in succession. Or different liquids may be employed in different groups of chambers. If the gas is at high velocity and in large volume two tunnels may be arranged in parallel and a separate external liquid conduit X, Fig. 11, provided with separate ponds each having a pump supplying sprays in the tunnel chambers. The partitions 1<a> - - 6<a> in this construction extend to the bottom of the tunnels, liquid from the sprays being returned to conduit X through piping 31.

Title: Apparatus for controlling fuel flow to an internal combustion engine
IPC: F02D3/02
Filed: 1973-04-18
Abstract: 1424069 Controlling fuel supply to engines J ZEYNS and H ENNEKING 18 April 1973 [15 May 1972] 18794/73 Heading F1B [Also in Divisions G2-3] Air-flow to an I.C. engine is measured by a device 11 and the amount of fuel distributed to the injection valves associated with the working cylinders is controlled in response thereto. The flow cross section of an opening 15 is controlled by the air-flow in channel 18 and a fuel pump 1 supplies fuel thereto by way of a flow resistance 7, the fuel then passing via a differential pressure regulator 25 and a constant pressure regulator 29 to the tank 3, a reduced control pressure downstream of the opening 15 being supplied to one side of each of membranes 61 of metering regulators 53, the membranes also being acted on by adjustable force exerting means (springs 193) and by fuel supplied to their opposite sides via metering resistances 55 to control the flow of this latter fuel to the injection valves (not shown). The constant pressure regulator 29, responds by means of a bellows 71 to ambient pressure and temperature to vary the mixture strength. Regulation of mixture strength for cold starting is provided by valves 67 and 79 responsive to bi-metallic regulators 70a, 70b on the engine 70. Valve 67 is also controlled to close when acceleration pedal 68 is fully depressed, so that laminar resistance 7a is connected into fuel control pipe 9 to lower the pressure therein and so cause mixture enrichment by reducing the pressure above membranes 61. Fuel supply to the injection valves is controlled by magnetic valve 65. The baffle 19 acted on by the airflow may be provided with an opening (81), Fig. 5 (not shown), whose flow cross section may be varied by a plate (83). A by-pass (89), Fig. 6 (not shown), may be provided around the baffle 19 and has a flap 91, which may be responsive to one of the bi-metallic regulators 70a, 70b. A turbulent resistance, 75, across which the pressure drop is proportional to square of the flow through it, is  formed as an apertured plate and enables the mixture to be enriched as engine power increases. The laminar resistances 7, 7a and 55 (Fig. 4) comprise pistons 173, 177 connected by rod 175 and slidable in fluid tight manner in a sleeve 171. The gap between the rod and the sleeve is about 80Á and can be made temperature-dependent by making the rod and sleeve of materials of different expansion coefficients e.g. steel and brass. Movement of the piston-rod-piston unit along the sleeve alters the flow resistance of the unit by altering the length of the laminar section of annular gap 191.
