Title: Improvements relating to vacuum brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1931-04-14
Abstract: 372,518. Vacuum brakes. GRESHAM, H. E. and GRESHAM, J. N., Ordsall Lane, Salford, Manchester. April 14, 1931, No. 10972. [Class 103 (i).] A quick release valve device for vacuum brake apparatus for railway &c. vehicles is adapted when the train-pipe pressure is reduced after an application, to connect the upper and lower chambers of the brake cylinder provided the vacuum in the upper chamber is above a predetermined minimum. The device comprises chambers e, f connected by passages b, c to the lower and upper chambers of the brake cylinder respectively and separated by a wall d through a passage in which projects a tubular member p normally supporting a ball valve q. The member p is carried by a diaphragm t which is open at its upper and lower sides respectively to the upper brake cylinder chamber and to the atmosphere. A spring u tends to depress the diaphragm t and its effect may be counterbalanced to a predetermined degree by a spring v adjustable by the screw w. A diaphragm m carrying a seat k for a valve i divides the chamber e from the chamber a which is connected to the train-pipe. The parts are normally in the position shown and the train-pipe vacuum is established in the various chambers. Air admitted to the trainpipe to apply the brakes depresses the diaphragm m and passes to the lower brake cylinder chamber through the annular passage n, the valve i being seated at h to prevent the air passing to the upper chamber. When to release the brakes the train-pipe pressure is slightly reduced, the diaphragm m raises the valve i off the seat h thus permitting air to pass from the lower brake cylinder chamber to the upper chamber through passages n, x, until equalization of the pressures in the chambers is effected, the vacuum in both chambers being subsequently restored to normal through the train-pipe by the lifting of the valve i. If during the connection of the upper and lower chambers the vacuum in the upper chamber falls to the value determined by the springs u, v the member p is lowered and the valve q seats at s to prevent further inlet of air to the upper chamber. This device enables repeated applications of the brakes to be made without complete restoration of the vacuum. A hand release valve 3 may be provided adapted to connect the chambers e, f, and thus the upper -and lower brake cylinder chambers.

Title: Improved electric incandescent lamp fittings
IPC: H01K9/04
Filed: 1928-04-14
Abstract: 308,494. Andersson, R. P. A. April 14, 19'28. Multiple-filament lamps; holders.-In bulbs of the kind having a rotary switch in the cap for the selection of the filament, the switch is arranged to enable the bulb to be used in an ordinary holder, in which case the filament is selected by the said switch only, or in a special holder containing or connected to a distant selector switch. In the construction shown in Fig. 2, the filaments 3, 4 are both connected at one end to the shell of the cap and at their other ends to contacts 21, 22 with either or both of which a switch arm 19 can contact. The arm 19 is carried by a metal tube 18 rotatable by an external disc 27, which may be turned by means having a handle projecting through the bulbholder socket. A central pin 16 insulated from the tube 18 is connected by a conductor 23 to the contact 21. Before inserting the bulb into an ordinary holder a filament is selected by turning the arm 19, but when it is inserted in a holder which has three contacts connected to three supply leads, the arm 19 is engaged with the contact 22 so as to connect the corresponding filament to a contact in the holder, while the other filament is connected through the pin 16 to a central pin contact in the holder. The filament is then selected by a switch fitted in the holder or located at a distance. The parts shown may be modified for use with a bayonetcap bulb. In the construction shown in Figs. 5 and 6, a rotatable selector disc 56 may be engaged with either or both of two contacts 51, 52 to which the filaments are connected, these contacts being connected to concentric metal rings 53, 54 on the opposite face of the plate. These rings have a wiping contact with spring fingers in the holder, or the fingers may be mounted on the plate and the concentric rings in the bolder. In the construction shown in Fig. 3, the two contacts 65, 66 of the selector are embedded in the insulating end 64 of the cap and are engaged by an external radial finger 63 to which pressure is applied by a spring 61. A ring contact 67 is in permanent connection with one contact for use in a holder connected to an external selector switch.

Title: Improvements in or relating to rotary duplicators of the kind using mirror-script originals
IPC: B41L11/08
Filed: 1953-04-24
Abstract: 725,604. Duplicating machines. RITZERFELD, W., and RITZERFELD, G. April 24, 1953, No. 11342/53. Class 100 (2). A rotary duplicating machine comprises, in the form of Fig. 1, a rotatable printing drum 1, in which a plurality of printing wheels 4, e.g. for printing num. bers, are rotatably mounted on a spindle 3, each wheel having a driving gear 5 attached thereto for rotating the wheel, each gear 5 being actuable by a rotatable toothed setting quadrant 8 connected to a member 6 having a series of recesses or the like 6b for facilitating rotating the quad. rant to set the printing wheels 4. The toothed quadrant 8 is mounted on a lever 14 pivoted on a pin 7. The member 6 is in the form of a quadrant extending from the lever 14. A scale 6a. fixed to each member 6, indicates which numeral on the associated printing wheel 4 corresponds to each recess 4. The printing wheels are set by inserting a pin or the like in the corresponding recess 6b in the associated member 6 and thereby displacing the lever 14 and quadrant 8 until the pin engages a cross spindle 11 on levers 12. The wheels are returned to initial position by displacement of levers 12 in the opposite direction against spring action. A cross-bar 13 then brings all levers 14 back into contact with a cross-pin 9. The wheels are retained against accidental movement by a spring- loaded pawl 10 engaging in a recess 6b of the member 6 of the setting means. A mirrorscript master sheet 30 is attached to the drum and extends round part of the circumference thereof. In the form of Fig. 3, the driving gear-wheels 5, attached to the printing wheels 4 are displaced by external setting gears 16 mounted on a shaft 17 carried by a lever 18 pivoted at 19. Another arm 21 of lever 18 carries a follower co-operating with a cam 20 rotatable on the shaft of the drum and controlled, for instance, by hand. A fall part 20a in the cam allows the setting gears 16 to engage the gears 5 at particular positions of the drum and cam. Recesses 16b are formed in the setting wheels which are each provided with an indicating scale as before. The setting wheels are displaced to return printing wheels to initial position by a cross-bar 13 mounted on levers 12. Before rotation of the drum 1, the wheels 16 are raised out of engagement with the gears 5 by rotation of cam 26. Pawls 25 prevent accidental movement of the printing wheels when disengaged from the setting gears, and spring-loaded pins 23 retain the setting gears against rotation when these are.in the disengaged position.

Title: Party-line metering in automatic telephone exchange systems
Inventor: SILVESTER JOHN STANLEY
IPC: H04M15/36
Filed: 1953-04-24
Abstract: 732,178. Automatic exchange systems. TELEPHONE MANUFACTURING CO., Ltd. March 8, 1954 [April 24, 1953], No. 11453/ 53. Class 40 (4). At substations on a party-line the dial and circuits are modified so that the dialling of the preliminary digit 0 transmits a number of loop impulses identifying the substation, this operation being recessary to prepare the exchange circuits for the reception of the wanted number. Substation, Figs. 1, 2. The dial is provided with additional contact-springs ON, O, M controlled by an auxiliary cam 5, ON being off-normal contacts, O contacts closed when the dial is pulled to its fullest extent and M contacts for shunting the normal impulse-springs D1. When the subscriber lifts his handset, the line will sound dead if the line is free since rectifier MRB is is back-biased. When he dials O, however, a loop is made over rectifier MRA and contacts O for relay S which energizes, locks and shunts contacts M across the impulse springs D1, so that the number of impulses sent over the loop depends upon the relative angular widths of the parts 9, 10 of the cam 5; as shown in Fig. 1, five impulses are sent. On the return of the dial to normal, relay S is shunted out by contacts ON, thus again breaking the loop through rectifier MRA. As a result the feed current is reversed at the exchange and the loop through rectifier MRB becomes effective. Exchange circuits, Fig. 3. The party-line is connected to relay A which energizes when the loop through rectifier MRA is established, followed by B, and repeats the preliminary impulse series to a relay chain PA ... PE, relays C, FP operating at the first impulse and CH if the number of impulses exceeds 5. At the end of the series C falls back and connects up R, and when the loop is again broken by the relapse of S at the substation the reoperation of C connects up reversing relay RV so that A re-energizes over the loop through rectifier MRB. The normal exchange apparatus is taken into use and dialled impulses are repeated by A. The meter M1 . . . M10 corresponding to the caller is selected by the operated relays PA . . . PE, CH. On a call to the party-line relay P operates to provide a straightthrough ringing circuit.
