Title: Improvements in or relating to frequency changing devices
Inventor: SALZMANN JEAN LOUIS
IPC: H03C1/58
Filed: 1960-09-29
Abstract: 902,986. Frequency-changing circuits; amplitude modulation. TELECOMMUNICATIONS S.A. Sept. 29, 1960 [Sept. 29, 1959], No. 33449/60. Classes 40 (5) and 40 (6). A frequency - changing arrangement comprises a ring modulator 12, to one diagonal of which is fed the signal to be changed in frequency via filter 4 and to the other the carrier frequency via transformer 14, 15. The output is obtained via a further filter 19 which is connected between a centre-tap on the transformer secondary 15 and a centre tap on the output of the filter network 4, which would normally be obtained by means of a further centretapped transformer. According to the invention, this is replaced by a pair of equal impedances 7, 8 which may comprise end elements of the filter 4. It is shown in the Specification that these impedances 7, 8, together with a negative impedance 20 which may be absorbed into the filter network 19 may be chosen to form an impedance network which is the exact equivalent of an ideal centre-tapped transformer. For this to be done, the filter 4 should terminate in shunt elements and filter 19 in series elements. It is alternatively possible for the impedances 7, 8 to comprise resistors and impedance 20 to be absorbed into a further resistor, forming output and input terminations for the filters 4, 19 respectively. The input and output of the arrangement may be interchanged.

Title: Improvements in or relating to starting of free-piston internal combustion engine gas generators
IPC: F02B71/04
Filed: 1945-12-11
Abstract: 605,009. Free - piston gas generators. VICKERS-ARMSTRONGS, Ltd., and DAVIS, D. E. Dec. 11, 1945, No. 33540. [Class 7 (i)] An opposed-piston free-piston internal-combustion engine gas generator is started by supplying compressed air to a cushion cylinder associated with each free-piston, either from a source or from a chamber which can communicate with the cushion cylinder by ports which chamber is connected to a source of compressed air and arranging that the air supplied to the cushion cylinders moves the pistons initially into a position in which the ports are uncovered so that the air in the chambers can effect the main starting stroke. As shown, chambers 6 can communicate with cushion cylinders 1 by ports 7, when cushion pistons 3 unmask the ports. A control valve 10 regulates the supply of compressed air from a source into the chambers 6 and cushion cylinders 1. The valve is first positioned to fill the chambers 6 and then turned so that it shuts off the air supply to these chambers and either connects the cushion cylinders direct to the source of compressed air or to the chambers 6. The air supplied to the cushion cylinders moves the pistons until the ports 7 are unmasked and the air from the chamber 6 then enters the cushion cylinders through ports 7 and effects the starting stroke. Non-return valves are provided in the air supply pipes to the cushion cylinders. As shown, compression takes place between the outer faces of the enlargements of the pistons and the ends of cylinders 2. The positions of the cushion cylinders and of the compression spaces may be interchanged or the cushion spaces may be at the outer side of a compressor cylinder in which compression takes place on an inward stroke.

Title: Railway axle counters
IPC: B61L1/16
Filed: 1970-07-10
Abstract: 1,253,958. Axle counting system. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. 10 July, 1970 [10 July, 1969], No. 33551/70. Heading B7N.  In an axle-counting installation residual counts of + 1 or - 1 are cancelled if a track circuit at the outcounting position is signalled as clear.  Assuming train movement in the direction P, track relay JX releases and via its back contact JX1 picks up directional relay FX whereby axle pulses generated by operation of relay BX are applied via contacts JX6 and FX5 to the incounting terminal E of counter Y. Additionally, relay G is released at contact JX3, the track section clear indicating circuit is opened at JX4 and on the count of two when counter relay Z1 picks up, auxiliary relay H is released via contact Z11. When the train has passed over the in-counting position, relay JX re-energizes and when it passes over the out-counting position relay JY releases so that out-counting pulses generated by relay BY are applied via contacts JY6 and FX6 to out-counting terminal A. Additionally supervising relay K is energized and held over its contact K1. After passage of the train relay JY re-energizes and assuming the counter has been returned to zero relay G is reenergized followed by pick up of relay H and release of relays FX and K. Under these conditions the clear indicating circuit is again completed. If after count down an error of e.g. + 1 exists in the counter, i.e., relay Zo still energized, and track circuit SY is clear with its relay JY picked up then relay X + 1 is energized and via its contact X+14 supplies a single pulse to terminal A to return the counter to zero. Supervisory relay K prevents operation of the correcting system if e.g. the arrangement becomes faulty when only one axle has been registered.

Title: A method of intensifying fruit or vegetable juice
IPC: A23L2/84
Filed: 1936-12-10
Abstract: The process described in the parent Specification is modified by destroying, prior to or during the concentration step, the gel-forming power of the pectin bodies of the fruit or vegetable juice by treatment with pectinase which may be added in the form of a preparation such as pectinol or the material known under the Registered Trade Mark "Filtragol."  The pectinase may be added prior to or after the dissolved solid content of the juice is raised to at least 50 per cent by weight.  It may be added to a previously concentrated juice to which fresh juice is added at a rate equal to that of evaporation of water therefrom.  Strawberry juice is concentrated to 6-7 times its original strength by including 1 lb. of pectinol in 100 gals. of the juice; raspberry and loganberry juices may be similarly treated.  With fruits, such as blackcurrants and stone fruits, containing pectin bodies of high gel-forming power, the treating material may be added to the fruit prior to expression of the juice.

Abstract: 381,017. Condensers. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Dec. 10, 1931, No. 34260. Convention date, Jan. 31. [Class 38 (ii).] In a rolled condenser, in which one at least of the conducting layers is interrupted to divide the layers into overlapping sections to obtain a series of part-capacities, the end surfaces of the roll are substantially funnel-shaped or conical with their apexes in opposite directions to provide an extended creepage path between the innermost and outermost sections which alone are connected to the terminals. Two convex ends, Fig. 2, or two concave ends, Fig. 7, are formed as follows. Each insulating layer is made up of a succession of strips of insulation 1 .. the width of which increases or decreases successively according to whether concave or convex ends are desired, the end of each strip overlapping the one previously wound. Each conducting layer consists of a succession of similarly graded strips 7 .. 12, preferably all being of substantially the same area, arranged in pairs in winding so that e.g. strips 7-8, 9-10, 11-12 overlap and are in contact. The gaps between the pairs in one conducting layer are made to lie opposite the overlaps in the other laver. Terminal connections may be led off from opposite sides as at 19, 20, Fig. 2. Fig. 7 shows a condenser 25 mounted on an insulating tube 28 in a casing 29. Terminal connections 26, 27 are led respectively to a metal cap 30 and a tubular lead in 35 packed in an insulator 37. The orifice at the end of the lead in is closed by a cap 51 which also serves as external terminal The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction in which, in winding the condenser, the conducting and insulating strips are moved along the axis of the spool to form one concave and one convex end to the roll. This subject-matter does not appear in the Specification as accepted.

Abstract: 358,333. Current, pressure, and power meters ; discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rex, H. B. ; 42, Magnolia Avenue, Lynn, Massachusetts, U.S.A.) Nov. 14, 1930, No. 34344. Convention date, Nov. 12, 1929. [Class 37.] In an alternating-current system in which currents proportional to the current or pressure to be measured are rectified and transmitted to a distance for measurement on direct-current instruments, the pilot circuits are protected against excess voltages by connecting across the pilot wires a device such as a gas discharge tube which permits initial passage of current only when the circuit voltage is in excess of the normal rectified voltage. A system is shown in Fig. 1 for measuring current, pressure and power at a distant point. A current transformer 14 has its secondary winding connected to the primary winding of a transformer 15, the secondary winding of which is connected to the anodes of a full-wave rectifier 18, preferably of the hot-cathode mercuryvapour type having its cathode supplied from the secondary winding of a transformer 19. From the mid-points of the secondary windings of the transformers 15, 19 rectified current is supplied over pilot wires 21, which may be telephone lines, to a direct-current ammeter 11. The resistance of the pilot circuit, represented diagrammatically by resistances 25, is adjusted to a standard value by a calibrating resistance 24. The rectified current is smoothed by a condenser 26, for example of 2 microfarads capacity, across the pilot circuit. Connected across the pilot circuit at the transmitting end is a neon tube 22 which will not pass current unless the line voltage rises above normal. Contacts 28 on the socket co-operate with contacts 29, Fig. 2, on the base of the tube 22 so that the pilot circuit is not complete unless the glow discharge tube is inserted in its socket. As a further protection a potential film cut-out 27 is connected in parallel with the glow discharge tube 22. A protective resistance 23 limits the short-circuit current in case of short-circuiting of the line 21 or breakdown of the tube 22 or film cut-out 27. A second pilot line 21<1> is similarly supplied with rectified current proportional to the voltage, and is connected to a direct-current voltmeter 12. A direct-current wattmeter 13 may be connected by switches 30, 31, 32 to read the voltamperes of the circuit.
