Title: Improvements in and relating to restraining devices for bogie trucks of railway and like vehicles
IPC: B61F5/48
Filed: 1929-03-28
Abstract: 308,826. British Thomson-Houston Co., Ltd., (Assignees of Kjolseth, O. K.). March 31, 1928, (Convention date]. Axle-trucks and bogies.-A resilient centering device 34, Fig. 1, for a bogie truck comprises a radius bar 22, a leaf spring 18 connected to the truck 16 and a lever mechanism comprising a rocker 21 connected to the spring for subjecting it to a bending stress. A platform 13, Fig. 3, is pivotally supported on a frame 14 mounted on trucks 15, 16, the truck 15 being rigidly secured to the frame whilst the truck 16 is mounted on a centre-pivot 17. The centering device 34 is interposed between the two trucks, one end being rigidly connected to the truck 16 and the other end, which is pivoted at 30 to the radius bar 22, is secured by the pivot 31 of the latter either to the truck 15 or to the frame. The centring device comprises a casting 23 rigidly secured to the truck 16 and is provided with openings for the insertion of a leaf spring 18 which is connected at its end to the truck 16 by links 19. A tension bar 27 is connected at one end to a strap on the spring and at the other by a pivot bolt 29 to a rocker 21. The bearings 26 of the rocker engage seatings 25 on the casing 23 and are maintained in contact therewith through the tension of the rod 27. Brackets 33 projecting from the bogie 15 overlap the rocker and prevent longitudinal rocking of the track bogie. When the bogie 15, radiates, one or other of the bearings 26 leaves its seating and compresses the spring 18 so that a restoring force to centralize the truck is brought into play. The friction in the leaves of the spring 18 prevent oscillation of the truck 16 and a constant restoring force is obtained by arranging the bearings 26 and the pivot 29 of the tension bar so that the distance from the axis of the tension bar to the trunnions is decreased at the same rate as the force of the spring is increased as the rocker is turned in either direction from its normal position.

Title: Improvements in and relating to centrifugal dust separators and collectors
IPC: B01D45/16
Filed: 1931-04-02
Abstract: 364,449. Centrifugal gas cleaners. TONGEREN, H. VAN, 26, Postlaan, Heemstede, Holland. April 2, 1931, No. 10020. [Class 23.] A centrifugal dust separator and collector has several dust outlets which skim the peripheral current in succession, the outlets being in positions determined by a formula given in the Specification. The complete separator is built up of units, one of which is shown in Fig. 2. A number of castings is held by bars 1 between a cover and a baseplate, the correct distances being secured by the use of pieces 2. In each unit the main stream of dust-laden air enters the curved channel 4 ; the dust particles are thrown to the outside of the channel and with a small quantity of air pass into the outlet 6 and thence to a small cyclone separator. The separating channel is long and has comparatively small radius and width. At the part 5 where the first skimming occurs, the curvature of the main channel reverses and the stream divides between the two channels 7, 8. Dust channels 9, 10 leading to the outlets 11, 12 are provided at the end of the channels 7, 8. Dampers 14, 15, 16, Fig. 1, may be used in the complete separator so that the number of units employed may be varied. Inclined conduits down which the dust can slide after separation may be used. In the modification shown in Fig. 3, the dust-laden gases are led through the conduit 20, and after passing through a complete circle the peripheral dust is removed at the first outlet 21 and passes to the cyclone separator 23. The gas stream is subdivided and passes through subsidiary channels and dust is removed through the outlets 28, 31, 34. With this arrangement of channels a long separating passage is assured. In the further modification shown in Fig. 5, the volute of the fan 31 is subdivided to form the separating passages the entrances to which are controlled by dampers 41. The peripheral dust streams are removed by outlets 42, 43, 54 and are discharged through lateral passages.

Abstract: 756,437. Semi-conductor devices. GENERAL ELECTRIC CO., Ltd. March 31, 1954 [April 14, 1953], No. 10188/53. Class 37. A method of making a contact assembly for a crystal contact device, comprising a support on which are mounted a plurality of mutually insulated metal members, and a plurality of contact wires each with a straight pointed part and an offset part, in which each offset part is fixed to one of the metal members so that the pointed ends are in close proximity and facing in the same direction, comprises the following steps. Each wire is brought into correct position relative to the support with the offset part contacting the respective metal member, to which it is secured while held in this position. The holding means allows free rotation about the axis of the pointed part, and is arranged so that the reaction exerted on the offset part is perpendicular to, but does not intersect, this axis. In Fig. 2 the metal members are tubes 2, 3 full of solder 9, 10 fixed on rods 4, 5 insulated from metal support 1 by glass beads 6, 7 and the straight part of the wire 11 is held by suction in the grooved end of pipe 22. The support 1 is held on a metal arm 20 by a spigot engaging hole 21. The pipe is moved towards arm 20 then downwards, when the wire comes into contact with member 9 which rotates it until the positioning movement is complete whereupon the solder is melted and resolidified to fix the wire. A second wire is fixed in the same way to member 10, the grooved pipe being rotated slightly in the vertical plane containing the straight part of the wire before the operation, to incline the wire so that it does not foul the other. The assembly is removed from arm 20, a Ge crystal on a metal rod is pushed through hole 21 into contact with the wires, and fixed by set screw 19, and the whole assembly enclosed in a case. In another embodiment (Fig. 4) the cylindrical support is of insulating material, with intersecting slots 27, 28 formed in its upper face. The support is fixed in a cup-shaped jig inclined at 45 degrees to the vertical (Fig. 5) with the pointed parts of the wires held between the flat face of jaw 44 and two V-grooves in the face of a second jaw 45, the jaws being a sliding fit in slot 28. After the wires are inserted through the grooves the offset parts fall under gravity into contact with metal members 31, 32 soldered in metal sleeves 29, 30 moulded in the support, and are soldered thereto. A metal rod supporting the crystal is inserted through the sleeve 26 moulded in the support the free ends of metal members 31, 32 are threaded through holes in the block, and the whole assembly enclosed.
