Title: Improvements relating to automatic telephone and like selective systems
IPC: B01D46/04
Filed: 1940-11-01
Abstract: 542,546. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., CHRISTIAN, D.A., and CLAY, D. L. Nov. 1, 1940. No. 15993. [Class 40 (iv)]. Several impulse-receiving arrangements are described in which the response to break impulses, particularly those received over a line of high capacity, is hastened by means of an nductive kick. In Fig. 1, a third winding of the impulse relay A is connected in series with a coil that is inductively coupled to the repeating coils RC, or, in the case of a Stone bridge, to additional coils in series with the relay windings, the arrangement being such that the induced voltage when a break occurs assists the release of the relay. The relay is preferably polarized to avoid the danger of a momentary operation by the inductive kick, but if it is not, its operation at a make will also be hastened. In Fig. 2, the inductive kick in a coil coupled to the repeating coils RC (or to additional coils in the case of a Stone bridge) is used to operate a highspeed relay X (polarized by a rectifier MR) which at make-before-break contacts momentarily completes a circuit through resistances NIR for dissipating the energy in the relay A and in the repeating coils. As a modification, instead of controlling the relay A, the relay X may open the outgoing circuit in advance of the release of that relay. In the case of a Stone bridge, the relay X may be connected in series with a third winding of the relay A. When repeating coils are employed, the relay A controls a repeating relay AA (not shown), the release of which may be initiated by the relay X in the arrangement of Fig. 2. The Provisional Specification describes another arrangement in which the two windings of the impulse relay are permanently shunted by inductance coils.

Title: Improvements in or relating to suspensions of vehicle bodies
IPC: B60G21/073
Filed: 1925-06-22
Abstract: 246,095. Mercier, J. G. Jan. 13, 1925, [Convention date]. Equalizing load on springs and wheels.- In a vehicle suspension comprising pneumatic springs arranged between the body and axles, additional pneumatic chambers of variable volume are connected to the springs and controlled in such a manner that they increase, the flexibility of the suspension for purely vertical displacements of the axles but give increased resistance to angular movements of the axles about the central longitudinal axis of the vehicle. In the arrangement shown in Fig. 1, the pneumatic spring comprising a piston 1 and cylinder 2 is connected to an additional chamber consisting of an air container 3, cylinder 4 and piston 5. The piston 5 of a suspension at one end of an axle is operated to increase or decrease the valume of air in that suspension accordingly as its piston 1 moves in the same or opposite direction as the main piston of the suspension at the other end of the axle. For this purpose, a two-armed lever pivoted to the underframe has one arm connected to the piston 5 and its other arm connected to the axle at the end remote from the piston 5. In the arrangement shown in Fig. 2, the pstons 1, 6 and cylinders 2. 7 of the suspensions at the ends of axle are double acting, the lower portion of each cylinder forming the additional chamber corresponding to the upper portion of the other cylinder. The portions of the cylinders are cross-connected for this purpose by pipes 8, 9. The Specification as open to inspection under, Sect. 91 (3) (a) also states that the operation of the piston 5, Fig. 1, may be effected by a servo-motor controlled by the displacement of one of the wheels. This subject-matter does not appear in the Specification as accepted.

Title: Cutter and method for cutting non-generated spiral bevel and hypoid gears
IPC: B23F21/22
Filed: 1966-04-13
Abstract: 1,072,208. Gear-cutting, GLEASON WORKS April 13, 1966 [June 1, 1965], No. 16193/66. Heading B3K. A method of finish-cutting tooth slots, which slots are of tapering width in a non-generated spiral bevel or hypoid gear having pre-cut sides which are surfaces of revolution about a first axis (12), Fig. 1 (not shown), comprises cutting one side of each slot as a surface of revolution about a second axis (12A) so as to taper the slot in width (cut 22) and then cutting the other side of the slot as a surface of revolution about the first axis 12 (cut 19). In the method, the axis of the cutter, Fig. 4 (not shown), remains stationary and the gear is indexed for the second cut. The resulting tooth space base surfaces are grooved as illustrated at (23), (24) in Fig. 3 (not shown) and the pressure angles of the teeth correspond to the cutter blade angles. The cut (22) is made by blades (26) to (37) and the cut 19 by blades (38) to (40). Blades 37 and 40 cut when no other blades are in the tooth space. The work is indexed in the gap 37-38. Tooth thickness may be varied by varying the indexing movement of the work. The blades may be integral, inserted or segmental. The blade (38) may serve only to skim the rough-cut surface. Cutting may take place from the wide to the narrow end of a tooth space and the cut (19) may then precede the cut (22), with the difference that the wedge-shaped cut (22) is taken from the convex side of a slot.

Abstract: 365,006. Canning food &c. CONTINENTAL CAN CO., Inc., 100, East 42nd Street, New York, U.S.A.-(Assignees of Troyer, N. and Pearson, P. E. ; 601, Myrtle Street, Seattle, Washington, U.S.A.) June 9, 1931, No. 16742. Convention date, Jan. 13. [Class 49.] In a can vacuumizing and sealing machine, wherein the receptacles, after passing down a conveyer 6 and being spaced by a screw 170 are passed by a rotating valve 9 into the vacuum chamber 1 where they are sealed by seamer heads 3, 4, and then out to a guideway 15, the valve 9 rotates on a spindle 67 and when necessary, e.g. when the machine jams, the valve and housing and conveyer may all be rotated away from the vacuumizing chamber around the stationary shaft 70, without breaking the gearing connection, thus retaining the timing of the valve relative to that of the seaming mechanism. Such gearing comprises spur gearing 85, 86, 88, 90, 91, 50, 51, worm gearing 56, 57, and a yielding coupling. This coupling comprises a disc 95, Fig. S, formed on a sleeve 96 splined on a shaft 58 ; a number of balls 100 in holes 99 in the disc 95 are forced by a spring-pressed plate 102 into holes 101 in a disc 98, but give under pressure. The disc 102 then operates through a lever on a shaft 131, Fig. 12, to open an electric circuit through contacts 136, 137, thus de-energizing a solenoid 115 and opening a valve 118 connecting the cylinder 110 to a source of vacuum through pipe 112. A piston. 111 is thus forced upwards and, through a rod 40, levers 44, Fig. 2, and a rod 37, Fig. 7, opens the main clutch 34 and applies the brake cone 35. If the vacuum in chamber 1 is broken, the solenoid circuit is broken at the contact 129 and the machine stopped as before. A hand-control lever 39 also is provided. The turret 12 which holds the containers is intermittently moved by a grooved cam 206 and pin-wheel 209 one-sixth of a turn between the seaming operations when the cans are elevated by pads 212 and grooved cams 220, 2201. Any water which collects in the machine is removed through a valve device.
