Abstract: 748,893. Commutators for dynamo-electric machines. HOOVER, Ltd. April 9, 1954 [April 14, 1953], No. 10210/53. Addition to 677,779. Class 35. [Also in Group XXII] A modification of the method of making a commutator claimed in the parent Specification comprises impact extruding a metal blank to form an annular member having a tubular wall, 11, Fig. 5, with internal fins 12 and an internal flange or a closed end 13, and at least one connecting tongue 14 for each segment, removing at least part of the flanged or closed end 13 so that at the junction between adjacent segments it will have the same inner radius as the tubular wall, moulding plastic insulating material 33, Fig. 11, into the tubular wall and then dividing the latter into seg. ments. A solid or annular disc of copper is placed in an extrusion die 15, Fig. 1, and pressure is applied thereto by a punch 26 to extrude the disc forwardly over a fixed vertical pin 19, having longitudinal grooves 25 which form the keying fins 12, and rearwardly into longitudinal grooves 27 in the punch which form the connecting tongues 14. The annular member thus produced is removed from the die by an ejector 24 operated by push-rods 23. The closed end 13 is then partly removed by punching to form the member of Fig. 8 (not shown). After the insulating material 33, Fig. 11, has been moulded between an inner bush 34 and the tubular wall, into which it is secured by dovetails 35 formed between adjacent fins 12, the commutator blank is inserted in a die 36, Fig. 9, and the connecting tongues 14 are first bent at right angles by a punch 37 and then bent rearwardly by a second punch 38. The tubular wall is finally divided by saw-cutting. The keying fins 12 of each segment may alternatively overlap each other or may be inclined away from each other.

Title: Hydraulic braking system control valve
IPC: B60T17/22
Filed: 1976-03-15
Abstract: 1527551 Dual vehicle braking systems AISIN SEIKI KK 15 March 1976 [13 March 1975 19 March 1975] 10213/76 Heading F2F A vehicle brake control valve has a stepped piston, or abutting pistons 8, 9 of different diameter so that increases in the actuating pressure generated in the master cylinder result in the pistons sliding to the left. This brings into play a proportioning valve 11 so that the pressure build-up in one pair of wheels 4 (preferably the rear) follows a different pattern from that in the other pair 7. The variation of pressure in the wheels 4 against pressure in the master cylinder is shown by the dotted line in Fig. 1a. The proportioning valve consists of a land 12 which runs in an orifice 15 and comes into contact with a seal 13. The pressure supply to the wheels 7 may be through a metering valve 38 which produces the pressure pattern shown in the solid line in Fig. 1a. The metering valve has a seal 30 between the inlet 5 and outlet 6 of the valve chamber. The seal is supported by a spring 37 and surrounded by an annular metering orifice 35, so that downstream pressure increases as a proportion of upstream pressure. However, there is also a rod 25 with two transverse slots 26, 27. If in the initial position, the slot 26 protrudes through the seal 30, this allows brake pressure to be applied to the brakes 7, i.e. up to A in Fig. la. However, as the pistons 8, 9 move to the left under increasing pressure, the rod 25, connected to the piston 8 by a rubber coupling 24, also moves to the left, and for part of the operating pressure range the only communication between inlet 5 and outlet 6 is around the periphery of the valve 30. This is the range BC in Fig. la. Further leftward movement however allows free fluid flow through the slot 27, and the pressure in the outlet 6 becomes substantially the same as in the inlet 5. This is shown by line CDE in Fig. 1a Failure in one of the brake circuits results in the pistons 8, 9 moving to the right or left beyond their normal range of travel. This raises a plunger to illuminate a warning signal 48. It also moves the land 12 in the one case, or the rod 25 in the other case, so that there is unrestricted flow of brake fluid to the operative brakes.

Abstract: 693,728. Photographic developing apparatus. KALLE & CO. AKT.-GES. May 1, 1951 [June 24, 1950], No. 10247/51. Class 98 (ii). Apparatus for the development of photographic diazotype prints with gas or vapour has a gas or vapour chamber and a main cylinder rotating partly within the chamber, a channel for the prints within the chamber and formed between the cylinder and a fixed guide grating spaced therefrom, and a second cylinder which is elastically mounted for rotation by and in contact with the main cylinder, which cooperates therewith to introduce the prints into the print channel, and which is confined between two elastic laminµ which bear on it in its rotation and one of which deflects the introduced prints into the print channel. As shown, the cylinders 2 and 3 elastically supported by levers (e.g. pressed by spiral springs) rest on the main cylinder 1, the prints being introduced between the cylinders 1 and 2 and passing along the guide grating 4 to be discharged between the cylinders 1 and 3. The laminae 5 and 7, which may be of thin spring steel and which slide elastically on the cylinder 2, are carried on the angle-bars 6 and 8, whose position is adjustable on loosening the screws 10. The end of the grating 4 projects through holes 5a. in the lamina 5. The gas or vapour chamber, enclosed by the wall 11, contains the heated ammonia vaporizing tray 12. In a modification, a grooved bar is attached to the lamina 5 to deflect the print between the main cylinder and the guide grating, the ends of which rest loosely on the bar. The use of cylinders providing a large number of rubber rings is referred to.

Filed: 1926-04-19
Abstract: 260,865. Fairweather, H. G. C., (Whittemore, Hulbert, Whittemore, & Belknap). April 19, 1926. Cleaning, fluid-pressure processes for.-A boiler clearer comprises a blower head 18, Figs. 1 and 7, rotated from a wormwheel 33 through a rod 20 and having tortuous passages formed by ribs 31, Figs. 1, 3 and 5, terminating in nozzles N<1> - - N<6>, inclined at different angles, the passages being fed with steam from a port 27, in the device shown in Fig. 1, with cooling-fluid from a port 30. In the device shown in Fig. 1, lubrication is effected by means of a piston 43 working in an oil chamber 40 and operated by the rotation of rod 20 and chamber 40, which moves the chamber 40 relatively to a screwed shank 44, the oil passing along a channel 38 in the rod 20 and through channels 52, 54. In the device shown in Fig. 7, a conduit 57 is provided for conducting steam from the inlet 25 to exert pressure on a piston 55. In this case, a thrust bearing 37 provided to take up end pressure due to the jets may be omitted, the effective area of the piston 55 being made to balance the blower head substantially against longitudinal thrusts. The moment of the transverse thrust R is also arranged to be balanced by the moment of the reaction F of the steam as it enters the tortuous passage, so that the blower head is balanced against the transverse reaction of the steam.

Title: An improved internal-combustion engine
IPC: F01B7/14
Filed: 1936-04-08
Abstract: 473,288. Driving gear for variablecompression-ratio engines. HELMORE, W., and GRIFFITH, A. A. April 8, 1936, No. 10291. [Class 7 (ii)] Adjacent cylinders 12, 13 having a common combustion chamber 19 contain pistons connected to separate crank or equivalent shafts which are geared together to rotate at the same number of revolutions per minute. For varying the phase of the crank-shafts, and thereby the compression-ratio, during running epicyclic gearing is arranged within the gearwheels 35. Each crank-shaft carries a sunpinion 25 in gear with a planet-pinion 26, the carrier 28 of which is externally formed with the gear-track 35. A further sun-pinion is mounted on a spindle 30 carrying a lever 32. The levers associated with each pair of crankshafts are connected by a link 33 for joint adjustment by a servomotor 54 responsive to oil-pressure, and controlled by a capsule 61 in communication with the engine induction pipe and by a rod 66 connected to the carburetter mixture control. With the linkage set as shown in Fig. 5 for maximum compression ratio, the torque reactions are equal and opposite and balance one another. In out-ofphase settings where the torque reactions on the two sun-wheels are unequal, the forces transmitted to the member 34 may still be balanced due to the unsymmetrical position of the members 32 and link 33. Where the engine cylinders are arranged side-by-side they are inclined to reduce the size of the combustion chamber, the inclined cylinder axes passing through the axes of the crank-shafts. The cylinders may, however, be placed end-to-end with a central combustion chamber, and crankshafts at each end, rotating oppositely and geared together by intervening wheels. Sleeve valves may be used.

Abstract: 527,177. Gas ovens. NEALE, J. E., and GUEST, A. April 3, 1939, No. 10297. [Classes 75 (i), 75 (iii) and 126] In a gas oven, burnt gases and heated air circulate along a passage encircling the oven chamber, from burners at the bottom and to one side of the chamber, the burner flames being prevented from impinging directly on the bottom of the chamber, e.g. by the downward extension of the side wall 12 of the chamber. Two burners 28 are enclosed in tubular chambers 36 slotted at the top for the flames and at the bottom for the entry of air. The tubes 36 can either be rotated through a right-angle or have slots in the side with sliding covers, to allow of access to the burners for ignition. The hot gases pass up the sides, down the back, between the bottom and a baffle 31, and under the baffle 31 to a rear outlet 33. The burner tube 29, Fig. 5, may be divided by partitions 44 into three parts each with a supply pipe 45. One, two, or all the parts may be selectively supplied with gas, Specifications 1125/01. 288,886, [both in Class 126], and 515,730 are referred to. According to the Provisional Specification, one or more of the passages for hot gases may have a spring-controlled vent which opens automatically in the case of explosion.

Abstract: 694,759. Automatic control systems. RHEEM MANUFACTURING CO. May 2, 1951 [Sept. 26, 1950], No. 10326/51. Class 38 (iv). [Also in Groups XVI, XXVIII and XXX] A control system, for maintaining a stack of steel sheets at an approximately constant height while the sheets are continually fed from the stack (see Group XVI), comprises an oil ram Fig. 1 (not shown), fed by an intermittentlyoperating pump which is controlled by two switches in series, one switch being responsive to depletion of the pile and the other being closed at regular intervals. The first switch 182 is controlled by a rocker 183 having a roller 184 riding the periphery of a cam 180 fast with a shaft 178 carrying a feeler 177 resting on the stack 32. Depletion of the pile causes engagement of the roller 184 by a recess 185 in the cam and closes the switch, which is in series with a solenoid 202 and a further switch 195 (Fig. 22). The solenoid, if energized, withdraws a pin 206 locking the piston 197 of an oil-pump 187 feeding the ram, each stroke of the pump being equivalent to several sheet-thicknesses. The rod 193 is connected to the piston by a lostmotion connection which permits its continuous reciprocation on a, crank disc 192 fast with a continuously-driven shaft 54. A lobe 194 on the disc 192 closes the second switch 195 momentarily once per revolution; if the first switch has previously closed the pin 206 is withdrawn and the pump operates to raise the stack by several sheet-thicknesses, thus opening the switch 182 until depletion again occurs.
