Title: Improvements in or relating to indicating or recording devices
IPC: G01L3/26
Filed: 1940-02-24
Abstract: 538,806. Indicating or recording apparatus. FULHAM, MAYOR, ALDERMEN AND COUNCILLORS OF THE METROPOLITAN BOROUGH OF, PARKER, W. C., and HUTCHINSON, J. Y. Feb. 24, 1940, No. 3509. [Class 106 (iv)] Apparatus for indicating or recording the ratio of two physical quantities comprises a balanced lever system to which forces proportional to the quantities are applied, means for restroing the balance after any displacement and means for indicating or recording the position of restoration. As shown in Fig. 1 for determining the efficiency of, say, a boiler, a balance lever is supported at 2 and carries at a fixed point a container 3 counter-balanced by a weight 4, the container 3 being adapted to receive a weight, say, sand or liquid, appropriate to the output of the boiler. A similar container 5 is arranged to slide on the lever and to be counter-balanced by a sliding weight 7. This container is adapted to receive a weight such as sand appropriate to the input of the boiler and means are provided for moving this container so as to restore the balance of the lever whereupon the efficiency is indicated by the pointer 20 on the scale 21 and if desired a time chart and pen may be provided for recording the efficiencies continuously. The means for moving the container 5 comprises a motor 15 operating a pulley 8 and cords 10, the motor being energized by a circuit which is closed through switches 16, 17 when the equipose of the lever is disturbed. Fig. 3 shows the means of feeding the sand by means of a hopper 34 having baffles 40, 41 constituted to permit a constant pressure head of the sand &c. Fig. 4 shows the means for varying the frequency with which the shutters of the hoppers are opened and also the length of time they are kept open. Two pendulums having bobs 42, 43 of magnetic material and cords 44, 45 the lengths of which may be varied to vary the periods of oscillation are mounted as shown in Figs. 3 and 4 and are normally maintained in their limit positions by electromagnets 47, 48. Pivoted strips 49, 50 of non- magnetic material are interposed between the electromagnets and the pendulum bobs and are operatively connected to the shutters of the hoppers. On breaking of the electromagnetic circuits by the unbalancing of the lever system the pendulums begin their swing and the shutters are opened by the strips 49, 50 which, aided by springs, rotate away from the electromagnets, switches being provided to prevent the electro-magnets being reenergized until the pendulums have nearly completed their return swings whereupon they are held in their limit positions.

Title: Improvements in or relating to variable speed driving mechanisms
IPC: F16H63/30
Filed: 1956-02-06
Abstract: 826,952. Change-speed and clutch control. FICHTEL & SACHS A.G. Feb. 6, 1956 [Feb. 10, 1955], No. 3620/56. Class 80 (2). In coincidental fluid-pressure clutch and gear-shift actuation, a manual selector lever 27, or push-buttons, operate one or more ratioshift levers 19 only after the main clutch lever 13 has been moved to disengage position, the clutch being allowed subsequently to reengage only after gear-shift pressure has exceeded a predetermined minimum necessary for gear-shift. The shift levers 19 are operated by compressed air motors 21 energized by selectively supplying lines 22, 23, 24 through a distributer valve 25 operated by the manual lever 27 and fed from a line 26 which is opened to the pressure side of a clutch motor 16 only when a piston 15 therein has moved the clutch lever 13 to clutch-release position, or directly pressurized by the clutch-lever 13 mechanically, electrically, or by fluid-pressure opening a valve connecting the line 26 to the pressure source. In operation, after pre-selecting a ratio by the manual lever 27 or push-button, a push-button of a switch 29 is depressed by hand, foot or by the shift-lever 27 or shiftbutton itself, to energize a solenoid valve 18 supplying compressed air to the clutch-motor 16 which, after disengaging the clutch, feeds the distributer valve 25 as above described, for gear shift. Automatic release of the pushbutton 40, Fig. 4, of the switch 29, Fig. 1, for clutch re-engagement is provided by a latch 45 which holds the button 40 in the depressed position and is released automatically after a predetermined time by a diaphragm 48, energized through a restrictor by the gear shift air-pressure 28, but only when said pressure exceeds (by 50%) the pressure necessary to actuate the shift mechanism. Where a separate clutch-controlled valve is used to supply the gear shift line 26, such valve may also be similarly opened only by clutch pressure building up to a value greater than that required for declutching. The transmission may include a hydrodynamic coupling or the main clutch may be a disengageable centrifugal one.

Title: Improvements in or relating to internal combustion engines of the compression ignition type
IPC: F02M45/06
Filed: 1938-02-05
Abstract: 507,940. Fuel-injection pumps. AUSTIN MOTOR CO., Ltd., and COLELL, R. F. Feb. 5, 1938, No. 3722. [Class 102 (i)] In a fuel-injection pump comprising two cylinders and pistons, each with a suction port and both pumping liquid fuel to an injection nozzle through a common non-return valve, the first or pilot cylinder K delivers its charge to the second or main cylinder C through the suction port S of the latter, from whence it passes to the non-return valve B and the nozzle, whilst the second cylinder C draws fuel from the supply chamber P through the suction port R of the first cylinder K, through such first cylinder, and thence through its own suction port S. The cylinders K, C contain pistons M, D, the heads m, E of which have the normal helical lower edges and grooves m<1>, e, the pistons being moved by cams Q, F, rollers q, d, a double-armed lever q<1> and a slide d<1>, against the action of coil springs H', H, the arrangement being such that piston M moves just before piston D. The pistons are rotated by racks N, j<2> which may be hand or governor controlled.

Title: Ciphering and deciphering device for teleprinters
Inventor: CUVELIER JEAN JACQUES
IPC: H04L9/38
Filed: 1959-02-03
Abstract: 865,938. Type printing telegraphy. ATELIERS DE CONSTRUCTION ELECTRIQUES DE CHARLEROI. Feb. 19, 1959 [Feb. 14, 1958], No. 3763/59. Class 40(3) A system of the type described in Specification 766,200, which comprises means for converting five unit code signals to a signal formed of two frequencies chosen from twelve, is modified in that the correspondence table is varied according to an arbitrary code which ciphers the five unit code signal by inversion of some or all of its code elements. Deciphering means is provided at the receiver. In operation, each clear five unit signal is converted according to the correspondence table, to two signals which are fed via two of twelve input terminals 1-12, Fig. 4, through relay contacts to two of twelve oscillators connected at 1<SP>1</SP>-12<SP>1</SP>. The relays 13-17 associated with the relay contacts are actuated by the presence or otherwise of perforations in a cipher tape containing five tracks. Thus if there is no perforation contact 18 does not close and an input on terminal 8 will pass to terminal 8<SP>1</SP> and cause an oscillator to operate. However, if relay 13 is operated due to contact 18 closing through a perforation, an input at 8 passes to 4<SP>1</SP> causing a different oscillator to operate. If relay 14 also is operated the output appears at 6<SP>1</SP>. The five unit signal is thus ciphered. At the receiver incoming signals are converted to five unit signals according to the correspondence table and fed to discharge tubes 57-61, Fig. 5. On reception of a signal on tube 57, relay 47 reverses contact 42 which operates the selector magnet 52. However if the cipher tape at the receiver indicates that that code element had been inverted at the transmitter, i.e. if contact 32 is closed, relay 27 reverses contacts 37 and the magnet 52 is then not energized. The received signal is thus deciphered. Alternatively the selector magnets 52-56 may each have two windings operating in opposition and fed one with the ciphered five unit element derived from the received signals and the other with a signal corresponding to a perforation in the cipher tape.

Title: Improvements relating to electrically-driven rotary pumps
IPC: H02K5/132
Filed: 1926-02-10
Abstract: 257,169. Drysdale & Co., Ltd., and Young, J. Feb. 10, 1926. Pumping-machines and apparatus.-A rotary pump b and the electric driving motor a on its shaft c are arranged for working in submerged positions, the casing being provided with a valve to prevent the liquid from reaching the motor when the machine is not running. The pump and motor are spaced apart by a hollow cylinder d, and the motor is hermetically sealed except at the gland e where the shaft leaves it. A ring g concentric with the shaft c is secured to a, flange on the cylinder d, and a valve ring h of the same diameter and width as the ring g is supported immediately above it on a flexible disc k, which may be of stainless steel, copper or other non-corrodible metal. The disc is clamped between a nut w on the shaft and an extension v on an electromagnet n. This magnet is energized, when the motor is running, through brushes t, u and slip rings s, r. Its core contains spring-pressed pins p which engage an armature ring m secured to the ring h. When the machines are not running the pins p keep the rings g, h in engagement so that no liquid can reach the motor. When the machines are running, the magnet n is energized and the armature m with the ring h is lifted against the pins p. The liquid is then prevented from entering the cylinder d by a centrifugal repeller 4 rotating with the shaft c and constructed like the impeller of a centrifugal pump.

Abstract: 347,335. Roads; paving blocks. MILLERS, J., 296, Kalker Hauptstrasse, Kalk, Cologne, Germany. Feb. 5, 1930, No. 3912. [Classes 87 (i) and 107.] A method of casting concrete road and like pavings in situ in blockshaped sections consists in casting each block against a block previously cast and against a removable mould which may have a face of sinuous or curved form. Each block (except the first) in each row, after the first row is cast, is moulded against the surface of the block previously cast in the row and against the surface at right-angles to it of a block in the row previously cast, the two remaining surfaces of the block being shaped by a temporary mould having two moulding surfaces at right-angles to each other. Before moulding a block, the adjacent faces of the previously-cast block are coated with an insulating layer of clay, tar, &c. to prevent adjoining blocks from adhering to each other. The sinuous-sided moulds form the blocks with curved sides, as shown, in order to provide an interlocking effect. The blocks may comprise an underportion of concrete containing gravel or ground slag and an upper portion of a coloured concrete.
