Title: A method of controlling the operation of a heat accumulator, and heat accumulator apparatus for use in carrying out the method
Inventor: GOLDSTERN WALTER
IPC: F01K1/00
Filed: 1969-06-06
Abstract: 1,246,568. Heat storage apparatus. W. GOLDSTERN. 6 June, 1969, No. 28795/69. Heading F4A. In a method of controlling the operation of a heat accumulator 20, the accumulator is charged through a regulator 22 whose setting is automatically altered in accordance with the charged state of the accumulator. The accumulator 20, preferably of the steam pressure differential type, is supplied by an automatic steam boiler 10 connected to a high pressure supply line 12 and discharges through a pressure reducing regulator 26 to a low pressure line 18. When there is peak consumer demand on the line 18, the accumulator charge (pressure) falls and an impulse is fed back through a conduit 24 to open the regulator 22 so that the boiler subsequently makes up the charge, but at a rate slower than the consumer rate. A further conduit 28 ensures that the supply to the line 18 is at constant pressure. The regulator setting may be varied continuously or discontinuously dependent upon the accumulator charge, Fig. 2 (not shown), or it may be constant over a considerable portion of the accumulator discharge cycle, Fig. 3 (not shown). The regulator setting may be adjusted to reach its maximum after only half the discharge cycle, Fig. 4 (not shown), thereafter being kept constant by an overriding control whereby, during the remainder of the cycle, the regulator is controlled directly by the boiler pressure via the conduit 30. The accumulator 20 may be a constant feed water accumulator with an output line 42 connected to the boiler 10 and with a cold water feed line 44; for supplying consumer hot water, a water outlet 46 is necessary. Alternatively the water accumulator may be used in conjunction with a closed heating system. In accordance with the type of accumulator used, the regulator 22 may respond to temperature, pressure or water level in the accumulator.

Abstract: 411,882. Hydraulic presses &c. TOWLER, J. M., Wells House, Thruscross, Summer Bridge, Yorkshire. Oct. 15, 1932, No. 28804. [Class 69 (ii).] Hydraulic apparatus such as presses, hammers, &c. comprises masses moving in opposition during the working stroke with equal and opposite momenta, one or more or all of such masses being intensifier rams. One form comprises a press ram e, Fig. 1, and an intensifier ram d. In the preferred form, the momentum of the press ram j, Fig. 2, is ignored, and opposed intensifier rams n are provided ; the non-working stroke is performed by setting a valve x so that liquid from a pump q passes along pipes v, air under pressure in the outer ends of the intensifier cylinders being thus highly compressed, so that it performs the working stroke when the valve x is opened. In a modification of this form, the intensifiers are set obliquely, and the momentum of the press ram is equal and opposite to the resultant of the momenta of the intensifier rams.

Title: Improvements in or relating to portable electric battery lamps
IPC: F21L4/00
Filed: 1931-10-19
Abstract: 392,595. Electric battery lamps. WILCZYNSKI, J., 116, Marszalkowska Street, Warsaw. Oct. 19, 193], No. 28965. Convention date, Oct. 18, 1930. [Class 39 (ii).] In an electric battery lamp the battery contacts 4, 5 are so arranged that, in the "off" position of the lamp, they are out of contact with both terminals of the incandescent bulb 7. In the example the lamp bulb 7 is screwed into a metal socket 6 which is adapted to be pushed into an apertured bulb support 2 mounted on the battery casing 1, the circuit being completed by the bottom edge of the socket 6 bearing upon a contact strip 4 connected to one pole of the battery, while the centre contact of the bulb extends through a gap in the strip 4 and makes contact with either the zinc bottom 5 of the battery or a spring strip connected thereto. The socket 6 may be screwed into the support 3 or secured therein by a bayonet joint. In a modification, Fig. 4, the bulb 7 screws directly into a support 2 secured to the top or lid of the casing 1, the contact strip 4 from one pole of the battery being arranged to bear upon the metal cap of the bulb when the latter is screwed home, while the central contact of the bulb bears upon the zinc bottom of the battery. The contact strip 4 is embedded between insulating layers 10, 11.

Title: Radio transmitter receiver which automatically switches to a ready-to-receive condition
IPC: H04B1/44
Filed: 1975-07-10
Abstract: 1476578 Radio transmitter-receivers INTERNATIONAL STANDARD ELECTRIC CORP 10 July 1975 [10 July 1974] 29041/75 Heading H4L A radio transmitter-receiver of the kind employing delta modulation for digital speech transmission in one of a plurality of channels, the modulator producing 0/1 sequences during silent intervals with a scrambler and an unscrambler adjusted to the transmitter-receiver's own address in the ready-to-receive state and switchable to a desired address for transmission, includes a timing circuit 17 which automatically switches the set to the ready-to-receive state if for a predetermined time the set has neither transmitted, nor received 0/1 sequences from another such set. In the receive mode the output of unscrambler 4 is connected via a switch 10 to an 0/1 sequence recognition unit 11. An output signal corresponding to the presence of an 0/1 sequence passes via a connection 15 to an OR gate 16 and starts timing circuit 17 producing logic "1" which then prevents channel switching unit 19 from switching local oscillator 21 to another channel. Timing circuit 17 also has connections to an AND gate 27 and to a control circuit 29, and if a push-to-talk button 30 is depressed while 17 is still on control circuit 29 keeps 17 on via a connection 39, and the output of AND gate 27 causes the set to switch to the transmit mode. If timing circuit 17 is off when button 30 is depressed a channel idle test unit 32 searches for an idle channel, and if it locates one it restarts the timing circuit and thus stops channel switching unit 19. At the same time a call timing circuit 33 is operated which first connects an 0/1 sequence generator 35 to scrambler 5 and then switches the latter over to a delta modulator 38 and microphone 37. When timing circuit 17 turns off, logic "0" applied over a connection 46 resets address input unit 36 to the station's own address. To insert 0/1 sequences into silent intervals during the transmit mode, a first embodiment includes connections 42, 43 to switches 10, 12 respectively, so that in the transmit mode the output of delta modulator 38 passes into 0/1 sequence recognition unit 11, the output of which passes into a further timing circuit 44 having a shorter time constant than timing circuit 17. After a silent interval of predetermined length, 44 switches 0/1 sequence generator 35 into the input of scrambler 5, for a period so brief that intelligibility is unaffected. In a second embodiment (not illustrated) the output of delta modulator 38 is applied to unscrambler 4 which is permanently connected to the input of 11.

Title: Improvements in or relating to apparatus for locating sunken torpedoes and other submerged bodies
IPC: F42B19/36
Filed: 1929-09-27
Abstract: 344,403. Locating and raising sunken torpedoes &c. PURVES, R., Air Ministry, Adastral House, Kingsway, London, and LAX, W. L., Royal Air Force Base, Gosport, Hampshire. Sept. 27, 1929, No. 29316. [Classes 9 (ii), 68 (i), and 68 (ii).] Relates to apparatus comprising a float normally kept in a recess in a torpedo or the like and adapted to be automatically released if the torpedo fails to come to the surface, the float then rising to the surface but remaining connected with the torpedo for the purpose of indicating the position of the torpedo and directing a hauling tackle thereto. According to the invention, the float consists of a self-inflatable collapsable fabric body 28, Fig. 12, containing a non-collapsable float 32 of rubber or cork, which is conveniently made in the form of a chair. A carbide cartridge is placed in a recess 33 of the chair and inserted with the chair into the collapsable fabric float 32, which is then folded over the chair, the seat 34 of which makes room for the reel 31 of the float line 27. The float device thus folded is inserted in a casing 1, Fig. 3, in the torpedo. This casing has a hinged lid 2 normally held closed by a lever 21 hinged at 20. When the torpedo is launched, water gets access to a soluble plug 7, Fig. 10, in a chamber 6 at the side of the casing 1 ; and when this plug dissolves away, a spring plunger 8 rises and rocks a trigger 17 which frees a pawl 19 fast with the pivot of the lever 21. This releases the lid 2, which springs open, whereupon the float device is ejected by a spring 25. The chair float 32 brings the indicator to the surface and erects the fabric float, while the carbide cartridge falls to the bottom of the fabric float where enough water percolates to act on the carbide cartridge. The gases thus generated inflate the fabric float. The release lever may be put out of action by locking it by a pivoted tab 23 unaffected by the soluble plug device. When the torpedo has been located, it is raised by means of a tackle 36, Fig. 17, which is lowered along the float line 27 and is provided with pivoted catches 39 adapted to engage a plug 49 on a short length of stout line 35 connecting the float line 27 to the torpedo.

Class 20 (ii) In a telescoping pit-prop the initial operating position of the vertical friction wedge 3, which moves with the inner prop member 1 for part of its descent, is determined by a distance piece 13 which is driven between the wedge and the lock 6 on the outer member 2 and then knocked out after this initial operating position has been attained. The downward movement of the inner member 1 is partly transferred to the wedge 3 by a stirrup clamp 9 which grips opposite faces of ribs 11 on the inner member when tilted. The inner member 1 is first set by hand and finally forced against the mine roof by a wedge 15, integral with the distance piece 13, acting through the clamp 9. Finally a horizontal wedge 5 is driven in to support the wedge 3 through an insert 4. During the collapse of the prop the movement of the wedge 3 is eventually stopped by its surface 12 engaging the lock 6 and the clamp 9 is stopped and released by engagement with a stop 23. In modifications wedges 15 are shown having rib or groove engagement with the wedge 3.
