Title: Improvements in or relating to devices and circuit arrangements in systems for charging electric batteries
IPC: H02J7/32
Filed: 1927-06-08
Abstract: 297,069. Mathisen, A. June 8, 1027. Charging batteries.-The charging of a battery is controlled automatically by an electromagnetic relay having a main armature adapted to be released at a predetermined battery voltage to commence the charging, but not operable by the magnet after release, and a secondary armature operated at a predetermined higher voltage to cause opening of the charging circuit. In one form the secondary armature energizes a timelag device which mechanically resets the main armature and stops the charge after an interval; alternatively the secondary armature may energize a switching device or may effect operation of a mechanical device which restores the main armature. The charge may be commenced at any time by manual operation of the main armature. Two relay constructions are described. As shown in Fig. 8 the main armature 2 is adapted to hold contacts r open while held by the coil R and the secondary armature 3 closes contacts X. The main armature may be manually operated and is adapted to actuate the secondary armature, to reopen the contacts X when it is mechanically restored. The time delay device comprises a member 5 operated by the expansion of a volatile or non-volatile fluid heated upon closure of contacts X and actuating a quick-action lever QS adapted to engage the armature 2 and reset it after a time interval controlled by a knob TS<2>. Figs. 10, 11 show an arrangement, particularly for a train lighting system, of a main armature 2 on stiff springs and an auxiliary armature 3 on lighter springs both subject to the action of coils R and operating contacts r, X in the manner described. The time lag device may comprise a bimetallic strip heated by a resistance coil or a fluid bath electrically heated and the time delay may be adjusted by tappings in the heating coil. The Specification describes the application of the invention to a small lighting plant with an automatically started prime-mover and generator, motor vehicle lighting and starting systems, trainlighting systems and to charging arrangements for high and low tension batteries for wireless receivers working off A.C. mains through thermionic rectifiers. The lighting systems include linked switches to vary the conditions of operation according as the lamp load is on or off. The thermionic rectifier arrangements include tapping switches varying the e.m.f. given according to the battery voltage interlinked with a resistance switch varying the resistance in the relay coil circuit and an accumulator stand adapted to switch off the main supply when the accumulator is removed. When associated with a wireless receiver the relay may be adapted to switch off the battery from the set when it establishes the charging connections. An arrangement is also described by which the engine of a motor vehicle may be left running to charge the battery and be automatically stopped on completing the charge by mechanically tripping an ignition circuit switch.

Abstract: 814,285. Gas turbine jet propulsion plant. SCHMIDT, F. A. F. May 31,1955, No. 15666/55. Class 110 (3). In an intermittent jet engine having one or more combustion chambers 1 to which air and fuel are supplied, at least a portion of the combustion gases are directed on to the blades of a turbine 6, and stationary transfer ducts 2, 7 are disposed between the combustion chamber or chambers and a rotary valve 3 which is driven by the turbine, the rotary valve being so constructed as to open the transfer ducts in succession to permit the discharge of combustion gases as high and low pressure gas streams, the low pressure gas stream acting on the blades of the turbine. In Fig. 1, the ducts 2 and 7 are radially and circumferentially displaced with respect to each other and the rotary valve 3 is ported as shown in Fig. 3c, the high pressure gases from the duct 2 and the low pressure gases from the duct 7 entering ducts 4 and 8 which supply turbine inlet nozzles 5, 9, the gases then impinging on the rotor blades of the turbine 6 and finally discharging to a propulsion nozzle. In Fig. 2a gases from the transfer ducts 11, 23 pass through ports in the rotary valve 12, the high pressuie gas stream from the duct 11 discharging through duct 22 direct to a propulsion nozzle, and the low pressure gas stream from the duct 23 discharging through a duct 24 to act on the turbine 13 which drives the rotary valve 12, the gases finally discharging to the propulsion nozzle. In this embodiment, the turbine drives also an air compressor 16 and further rotary valves 15, 14 which control the air inlet to and gas discharge from the combustion chambers. In Fig. 2b the rotary valve and turbine are combined in a single disc 17 having ports in its periphery, turbine blades 21 being disposed in the ports but not extending the full radial height thereof. Low pressure gases from the transfer duct 23 impinge on the turbine blades 21 thereby driving it and high pressure gases from the duct 11 pass through the ports in the valve without impinging on the turbine blades and then pass direct to the propulsion nozzle. An air compressor 20 and further rotary valves 18, 19 driven by the turbine are provided in this embodiment also. The rotary valve may be hollow and cooled by air-flow therethrough.

Title: Improvements in Autographic Registers.
Inventor: IMRAY OLIVER
IPC: B41L5/06
Filed: 1919-06-23
Abstract: 136,116. Imray, O., (American Salcs Book Co.). June 23, 1919. Memorandum appliances.-Consists of a multiple web register having means for feeding the webs over a support and adapted to stop the feeding of each web as it reaches a predetermined position, independently of the other webs, the amount in each case, being determined by the construction of the web. Improved webtensioning means are also provided. 'The rolls are mounted in a casing having hinged top plates 5, 6, Fig. 2, the plates 5 serving as a writing support, between which plate the webs issue. The webs are supported on lugs 11 attached to side plates 3, 4, Fig. 3, the lugs having vertical and inclined portions 12, 13. In the pockets thus formed rest the rolls, the first pocket being completed by stop lugs 15. Antifriction rollers 17 may be provided against which the rolls bear when the tension of the webs, passing over guide-rollers 16, causes the rolls to rise. From the rollers 16 the webs pass over the plate 5 and between disks 22, on a cross shaft 20 operated by a handle 21, and rollers 26 on a shaft 25 journaled in brackets 24 and depressed by springs 27. Gears 30, 31 drive the rollers 26 at the same speed as the disks 22. In longitudinal alinement with the disks, the webs are provided with perforations or cut-away portions such as 45, 46, 47, Fig. 6, the distances between the rows of perforations being the lengths of the sales slip or the like on each web, which distances may be equal or otherwise. The perforations are wider than the disks 22, so that when a perforation comes over the disk, feeding of the web ceases, but any webs whose perforations have not registered will continue to be fed. The disks 22 have a circumference slightly longer than the longest stale-clip. A complete revolution of the handle 21 thus brings all the slips into proper alinement together with any carbons which may be interleaved. At the end of the revolution a spring-pressed bolt 38 locks the handle. To move the webs to feed the next sales slips, the disks 22 are provided with blocks 34 wide enough to engage the webs beyond the sides of the perforations, which blocks come into action just before the handle locks. To aline accurately a large number of webs, pins may be provided between the sides of the blocks 34, which pins bear against and lift the rollers 26, after the blocks 34 have moved the webs slightly, and the tension on the webs thereupon draws them back until the pins engage with the advance edges of the perforations to secure accurate alinement. A tearing-bar 42 is provided as shown.
