Patent GB-259194-A (GB)
IPC: B60T13/66
Filed: 1926-09-07
Abstract: 259,194. Compagnie Internationale des Freins Automatiques Soc. Anon. Oct. 5,1925, [Convention date]. Electric and magnetic; fluid-pressure.-In a braking device for a vehicle, the brake is applied (1) by the core of a solenoid excited by current from a generator actuated by the vehicle or by the vehicle motors acting as generators, and (2) by the core of a second solenoid subjected to the action of fluid under pressure and displaced in the opposite direction by an exciting current from a source on the vehicle to release the brake. As shown in Fig. 1, the two solenoids are combined in a single solenoid 1 with a core 2 slidable in a tube 3 of non magnetic metal and under the influence of two windings 12 13. The core is connected by a rod 4 at one end to the brake mechanism 5, 6 and the tube 3 is connected at the other end by a duct 8 to a vessel 9 containing fluid under pressure, an automatic valve 10 in the duct being normally held on its seat by the pressure fluid and adapted to be opened by the action of an electromagnet 11. One end of the winding 12 is earthed and the other is connected, through the electromagnet 11 to the positive terminal of the motor acting as generator when the main control handle 15 is moved past zero, so that the core 2 is moved to the left to apply the brake under influence of the winding 12 and also by fluid pressure as the valve 10 is opened by the electro. magnet 11. As the speed of the vehicle decreases, the braking action is diminished until it is due solely to fluid pressure. Release of the brake is effected by moving the handle 15 to the zero region where, it causes a contact stud in the circuit of the winding 13 to abut the sector of the controller and close the circuit which includes a source of current, so that the core 2 is moved to the right and returns the pressure fluid to the vessel 9. The controls may be separate instead of combined, and the electromagnetic brake may be graduated by interposing more or less resistance in the circuit. The valve 10 may be held on its seat against the pressure of the fluid by an electromagnet 16, Fig. 2, normally energized, another and stronger electromagnet 11, or another winding on the electromagnet 16, being employed to open the valve when required and a check valve 17 being provided for the return of the fluid to the vessel 9. This arrangement is suitable for trailer vehicles, the circuit of the electromagnet 16 being broken automatically if the trailer coupling is broken.

Title: Processing photographic sheets
IPC: G03D9/00
Filed: 1973-05-09
Abstract: 1377457 Processing photographic sheets POLAROID CORP 9 May 1973 [23 May 1972] 22098/73 Heading G2X In processing an exposed photographic layer supported between two superposed sheets by means of introducing processing liquid between the sheets, pressure is applied to first and second spaced linear portions of the sheets, the sheets and pressure-applying means being then moved one relative to the other, and the two sets of pressureapplying means being moved towards each other so that the volume of the liquid-filled region is progressively reduced. The film sheets are of the type in which a rupturable container 16, Fig.1 (not shown) holding a supply of processing liquid 18 is secured between a photo-sensitive sheet 12 and an image-receiving sheet 14. Such an arrangement forms a unit, of which several are provided in a cassette 40. The pressure-applying means comprise two pairs of rollers, 42, 44 and 66, 68. The rollers in each pair are mounted so that they can move apart, but are spring-biased towards each other. Each pair is also mounted in respective support members 46 (comprising parts 48, 50) and 70 (comprising parts 72, 74). Members 46 and 70 are spring-urged together, and can telescope one within the other. The leading end of a film unit is fed forward between rollers 66, 68 (temporarily spaced apart to allow passage of the container 16) into the bite of rollers 42, 44, as shown in Fig.7. The hydraulic pressure exerted by the liquid 18, after it has been freed from the container, separates the portions of the sheets  intermediate the two linear regions where pressure is applied by the two roller pairs, as seen in Fig.7. Thus all portions of the facing surfaces of sheets 12 and 14 are certain to be contacted by the liquid. As liquid is gradually absorbed by the sheets, the quantity remaining becomes less. However, as the two sets of rollers are moved towards each other, as shown in Fig.8, this quantity is still maintained under sufficient hydraulic pressure to hold the facing surfaces apart. In a further embodiment, Figs. 12-15 (not shown) the film unit is held stationary and the pressure-applying members are reciprocated with respect thereto. The film units in this case may be joined together in the form of a long continuous strip, as in Figs. 10 and 11 (not shown). The arrangement of the invention is particularly convenient for use with processing liquids of low viscosity.

Title: Method of and apparatus for the concentration or purification of caustic soda or other suitable material
IPC: C01D1/42
Filed: 1925-09-05
Abstract: 265,252. Hammond, C. F., and Shackleton, W. Sept. 5, 1925. Coking processes.-The material to be treated, for example comminuted solids such as sawdust, coal, vegetable matter or refuse, is conducted over the surface of a hot liquid mass, for example lead, heated directly by gases of a submergedflame burner, the products of combustion being withdrawn at a portion of the surface which is not covered by the material under treatment. In the example of an apparatus shown in the figure the hot liquid mass is contained in a vessel a, which may be heated at starting by an external furnace. During the treatment a submerged-flame burner extends down the central sleeve o and the products of combustion rise within the screen b and after baffling at r escape through the outlet m. A circulation of the liquid contents is thus set up, the mass passing outwards through the ports f in the wall e and over and under the baffle d. The material to be treated is caused to flow in a substantially circular path on the surface of the mass between depending walls g<2>, g<3>, g<4> carried by the cover g, suitable inlets and outlets being formed by tubes projecting beneath the surface of the mass.

Title: Calculating machines
IPC: G06F7/46
Filed: 1929-07-20
Abstract: 328,171. Tauschek, G. July 20, 1929. Dividing-apparatus.-In a machine with a laterally movable totalizer carriage the division process is performed automatically by an electric circuit arrangement controlling the relative movement of the operating parts. As shown the dividend is set up on the totalizer pinions in the carriage 1, the divisor is set on the differential setting mechanism 2 and the carriage displaced to the appropriate position. On depression of the division key 4 contacts 25 are closed and a magnet 6 is energized through closed contacts 5. The armature of the magnet 6 inserts a clutch member 7 which couples the motor driven shaft 8, through bevel gearing 9, 10, to the main shaft of the machine. The operation in this position is continued until the highest denominations of the totalizing-counter register 9's causing a reading in the quotient counter which is one in excess of the true value. Movement of the highest numeral wheel to the 9 position closes a pair of contacts 12 to energize a magnet 13 the armature of which opens contacts 5 and inserts a clutch disc 14 to cause a single rotation of the main shaft in the additive direction. The clutch 14 is maintained in closed position after the magnet 13 has been de-energized by a nose 15 on the clutch disc engaging the outer surface of a single notched member 16. During this single rotation a cam 17 on the clutch disc closes contacts 18 to energize a magnet 19 adapted to effect the operation of the carriage shift mechanism. The process is continued in the next denomination and so on until the carriage reaches its end position whereupon a contact 22 on the carriage engages a contact 23, and through a pair of-contacts 21 closed on the energization of magnet 19, energizes a magnet 24 to free the division key.

Abstract: 276,682. Lomar, L. L. Aug. 26, 1926, [Convention date]. Fluid-friction vibration-dampers.-In one-way or differential apparatus adapted to be disposed between relatively movable parts of a vehicle, and in which a piston movable in a closed casing is connected to a hollow piston-rod which provides a passage for fluid from one side of the piston-rod to the other, the area of the passage, is controlled by a tubular valve member extending into the piston rod. The piston 5 is guided in the cylinder 1 by rods 4 fixed in the cylinder ends 2, 3 and is formed with openings covered by-one way hinged valves 33, 34. Fluid passes from one side of the piston to the other through the holes 14 in the hollow piston rod and the slot 15 in the tubular valve 9, the slot being tapered to increase the resistance upon displacement of the parts from their normal position. The valve 9 may be rotated about its axis to vary the passage area by means of an external lever 46. A plunger 42 provided with a one-way valve 43 is pressed downwards by a spring 41 on to the end of the tube 9 and yields upwardly under excessive fluid pressure. The space above the plunger 42 forms an oil reservoir from which wastage in the apparatus is automatically made good through the valve 43.
