Title: Improvements in electric braking
IPC: B60L7/12
Filed: 1929-08-20
Abstract: 337,859. Stevens, W. A. Aug. 20, 1929. Controllers with brake devices; electric braking systems.-In a system of braking compoundwound traction motors, rheostatic braking is resorted to after regenerative braking has ceased'. During running and regeneration, the motor 1 is controlled by a pedal-controller 22, successively energizing series resistance contactors 16, 16<x>, and thereafter inserting shunt field resistance 5. A brake controller 22<a>, pedal-operated by the same foot as the driving controller, when depressed energizes contactors 31 and 34. The former completes the armature circuit through the normal starting resistance, and its auxiliary contacts 31b complete the shunt field circuit, and the latter short-circuits the series field 2. Further movement of the controller 22a gradually short-circuits shunt-field resistance 5<a>, the resistance being short-circuited during running by a contactor 168. Various modifications are disclosed. During braking the shunt field instead of being separately-excited, may be self-excited, and a relay may be provided to change over from the former to the latter should the supply fail during braking. The brake pedals may, in its various positions, control the series resistance contactors 16, 16<x>. The driving and brake controllers may be so associated electrically, that if both pedals are depressed together, the driving controller is inoperative. And a single pedal and controller may be used in conjunction with a manually-operated switch for both driving and braking connections. Specifications 278,073 and 330,259 are referred to.

Title: Improvements in and relating to apparatus for the manufacture of ceramic tiles
IPC: B28B13/02
Filed: 1921-09-24
Abstract: 193,888. Thompson, W. P., (Soc. Anon. la CÚramique Nationale). Sept. 24, 1921. addition to 16923/12. Feeding and measuring; pattern plates. - In apparatus for manufacturing ceramic tiles as described in the parent Specification, the strainer through which is fed to the moulds is shaken by the relative movement of the strainer itself and a movable body carried thereby, caused by the action of a fluid under pressure, which also effects the necessary movements of the moved frame and its reversal to remove surplus material. The strainer 7, Fig. 4, is movable in grooves formed in the ends of a hopper 14 and carries a cylinder 6 in which a body formed as a differential piston 5 is reciprocated by means of compressed air introduced through a pipe 1. The piston 5 has two faces 3, 7<1>, Fig. 10 the annular face 7<1> being of lesser area than the face 3. The compressed air acts directly on the face 7<1>, and on the face 3 through a passage .4, and owing to the difference in the areas of the faces moves the piston in the direction of the arrows until pressure in the face 3 is diminished by the passage 4 coming into communication with an outlet port 6, whereupon the piston is returned to its former position by the residual pressure on the face 7'. Springs 10 attached to brackets 8 assist. the return movement. Material is allowed to pass through the hopper 14 by a movable damper 16 having openings 26 which are made to coincide with similar openings in a fixed plate 15 by the agitation of the strainer 7 and the reaction of springs 20 attached to brackets 22. A mould frame 27, Fig. 2, is moved to and from underneath the hopper 14 by means of a second differential, piston 31. The frame 27 is mounted on spindles supported by elliptically shaped bearings 44, 45, and is reversed when it engages in recesses 140 termed in discs 38 mounted in jaws 138, by rotation of the discs 38 by a third differential piston 41 operating Through rack and pinion gearing 39, 40. The frame 27 is positioned during filling by the bearings 44, 45 engaging in notches 12, 43, from which they are subsequently lifted. by arms 46, 47 of levers 48, 49 operated by cams 50, 51 on a shaft 53. Rotation of the discs 38 during the positioning of the frame 27 is prevented by pins 56 acted on by spring 57. When a series of strainers is used, the pressure fluid is distributed to the larger faces of the pistons in cylinders 32, 32<1>, 32<11> and 41, 41<1>, 4<11>. Fig. 6, by distributor 108, 109, the smaller piston faces being connected to a pipe in which constant pressure is maintained and which is connected with distributors 107, 110.

Filed: 1929-08-22
Abstract: 327,936. Crisenberry, B. F. Aug. 22, 1929. Syringes.-A syringe, especially adapted for vaginal use, comprises a collapsable resilient bulb 1 and a nozzle 3, flaring externally and of oval construction at its larger end. The open end of the nozzle contains an internal curving seat 4, so that a tapered valve 5 engages therewith on a relatively narrow zone and at a distance from the edge, thereby avoiding pinching between them. The valve head is adjustably attached to the rod 7, which can slide between guiding ribs 9. The headed end of the bolt 11 receives a disc 12 which operates so as to close the return holes 13. In operation, the bulb is fitted with the desired fluid and squeezed, thereby raising the valve structure 5, 7, and 12. The liquid passes through holes 16 and annular groove 15 in the disc 12, through the passages formed by the ribs in the nozzle and discharges in a conical sheet. On allowing the bulb to expand, the valve structure 5, 7, and 12 shifts, thereby seating valve 5, and opening holes 16, thus causing the liquid to return to the bulb through grooves 14. The force with which the water is discharged is regulated by adjusting the head of the valve 5 on the bolt 7.

Title: A device for indicating the average pressure in the working spaces of machines operating with a periodically varying pressure
IPC: G01L23/02
Filed: 1921-09-30
Abstract: 190,814. Strack, J. Sept. 30, 1921. Bourdon pressure gauges; applications of; mounting-details for; damping arrangements.- An apparatus for determining the average pressures at various points (e.g. in the several cylinders) of engines working with varying pressures consists of a liquid-filled pressure gauge in throttled communication with a liquid-filled chamber separated by a flexible diaphragm from another chamber which can be put into commurication with any one of these points by a selecting device. A Bourdon-tube gauge 6 is filled with glycerine and separated by a diaphragm 10 from a chamber 29 which is connected by a pipe 15 with the selecting device. As variations of pressure are damped by the glycerine being forced through the throttling passage 8, steady readings are obtained. The selecting device operates control valves and comprises a shaft 23 rotatable in a casing 17 provided with ports 18 leading to the various points of the engine (e.g. opposite ends of the same cylinder) each having a valve 19 normally closed by the working pressure helped by a spring 20. Cam-shaped grooves 22 on the shaft engage these valves to lift them and are arranged so that only one valve is lifted at a time as the shaft is rotated by hand. Thus any point may be put into communication with the gauge at will, and in high speed engines the average pressure will be indicated. The adaptation of the invention to elastic diaphragm and to liquid-level pressure gauges is also described.
