Abstract: 1515205 Testing ignition systems of IC engines APPLIED POWER Inc 29 July 1976 [30 July 1975] 31678/76 Heading G1U An apparatus for testing the ignition system of an internal-combustion engine is characterized in that it includes means for producing timing pulses that occur approximately mid-way between successive firing pulses from the firing pulses themselves (i.e. from the voltage across the secondary of the ignition coil). This arrangement is necessary when testing electronic ignition systems, since with such systems it is not possible, as with conventional mechanical ignition systems, to derive timing pulses (that would have been called "points-close timing pulses") from the primary winding of the ignition coil. As described the coil secondary voltage Fig. 2A is inductively sensed to produce pulses Fig. 2B at the firing instants. These pulses are then applied to a bi-stable circuit to produce a signal Fig. 2C at one-half the firing frequency. This signal is integrated and centred about zero volts, Fig. 2D, rectified Fig. 2E, differentiated and limited Fig. 2F, to produce a signal at the firing frequency and the positive-going excursions a", c", ..., of this signal, extracted by further differentiation, form the required timing pulses. A detailed circuit, Fig. 1A, (not shown) using conventional integrated blocks, is described for performing these operations. The particular test apparatus described can be used either for conventional mechanical ignition systems, in which case timing pulses are obtained from the ignition coil primary by a connector 75, Fig. 1B (not shown) with a switch 237 in its lower position, or for electronic ignition systems in which case timing pulses are produced as just described and the switch 237 in its upper position. Each timing pulse advances a ring counter so that each stage goes on one-half cycle ahead of the firing of the corresponding cylinder. The counter is reset to its first stage by a pulse from the plug of number 1 cylinder. By closing any one of switches 54, 55, ..., 59, the corresponding cylinder can be disabled and the effect observed. A c.r.t. 170 is arranged to display successive coil secondary pulses.

Title: Improvements in jet propulsion plants, in particular for aircraft
IPC: F02B71/06
Filed: 1947-12-01
Abstract: 629,920. Jet-propulsion gas turbine plant. SOC. INDUSTRIELLE GENERAL DE MECANIQUE APPLIQUEE (S.I.G.M.A.). Dec. 1. 1947. No 31703. Convention date, Nov. 29 1946. [Class 110(iii)] The turbines 1, 2 can be worked either in series or in parallel. For series working, the compressor 5 is disconnected. The air compressed in low and high pressure compressors 3, 4 is heated in combustion chambers 10 and delivered to turbine 1. The exhaust from turbine 2 goes to a propulsion nozzle 16. For parallel working, the compressor 5 is coupled by a clutch 23, and the valve 15 connects conduits 14a and 28 so that the compressor 3 delivers air to the two compressors 4, 5. Air from the compressor 5 is heated in combustion chambers 25 and passes to turbine 2. The exhausts of the two turbines go to a collector 31 and thence by a conduit 33 to a propulsion nozzle. In series working, some of the air from compressor 3 passes through valve 15 to a conduit 14b and thence to a propulsion nozzle. Part of the working fluid tapped between the two turbines may also pass through valve 19 to the same nozzle. The compressor 4 and combustion chambers 10 may be replaced by a 'free-piston generator which is charged by the compressor 3 either from its delivery or from an intermediate tapping. The free-piston generator may take in atmospheric air and supply the whole of the working fluid for series working; the whole delivery of the compressor 3 being sent through the conduit 14b to a propulsion nozzle. The nozzles fed by the conduits 14b, 33 may be mounted on a helicopter or rotary wing.

Patent GB-539699-A (GB)
Title: Improvements in and relating to aerial bombs
IPC: F42B25/00
Filed: 1939-12-08
Abstract: 539,699. Aerial bombs. KENT, C. W. Dec. 8, 1939, No. 31792. [Class 9 (i)] An aerial bomb having direct-acting detonating-means operated by impact is fitted with a nose-portion 13 adapted to be sheared from the main body 9 on impact with water, leaving one or more oblique surfaces 14 which cause the bomb to be diverted towards, or out of the surface of the water, delay-action detonating-means being provided to operate after a pre-determined lessening of the water resistance. Figs. 1 and 6 show the bomb in its composite form, and Figs. 5 and 7 after removal of the detachable nose-portion. The latter is normally secured to the body portion by means of interengaging tongues and grooves with or without catch-means such as a removable locking-pin, or a spring detent. A firing-pin 21 on a rod 20 is normally held at safety by a pin 23 engaging a sleeve 18, the pin being sheared on impact of the sleeve on the ground or other hard object such as a ship 34, Fig. 8. The delay-action means, which become operable when the noseportion 13 is removed, comprise a flap 26 pivoted on a guide-bearing 22 for the rod 20, and formed with detents 29 normally engaging lugs 32 on a rod 30 swung from a collar 24 slidable on the rod 20. In this position (Fig. 6), a spring 25 is compressed between the collar 24 and the sleeve 22. As the bomb enters the water, and is diverted along paths such as 37, 44, 40, Fig. 8, the reaction of the water against the flap 26 at first overcomes the pressure of the spring 25 which ultimately reacts to disengage the detents 29 from the lugs 32. The collar 24 is then forcibly urged against the flange 33 of the firing- pin to explode the bomb as indicated at 38 or 42, Fig. 8. The same Figure indicates impact explosion at 36. 45. To enhance the diversion of the submerged bomb, one or more tail fins 11 may be pivoted in an unbalanced arrangement so as to produce a hydroplane effect as indicated at 41, Fig. 8. In modifications (not shown), the main portion may comprise a series of bomb elements having differentlydirected diversion-surfaces so as to increase the effective area of operation.

Title: Improvements in and relating to electric cable installations
IPC: H02G15/26
Filed: 1932-11-10
Abstract: 410,124. Cables. CABLON, Ltd., 296, High Holborn, London. Nov. 10, 1932, No. 31831. Convention date, Nov. 19, 1931. [Class 36.] In a pressure cable system having either oil-filled cables of the usual type installed in a pipe line containing gas under pressure as described in Specification 366,673, or employing oil-filled cables having internal pressure ducts of the kind described in Specification 264,135, [Class 36], damage to the cable due to failure of the pressure system is prevented by means which automatically ensure that the pressure in the oil expansion reservoirs and oil ducts shall never exceed the pressure existing in the pipe line or pressure ducts. For this purpose the oil expansion reservoirs may be disposed in casings containing a gas under a pressure which is maintained or controlled by the pressure in the pipe lines or pressure ducts. Fig. 1 shows such a system wherein oil expansion reservoirs 8 of a cable 1 are mounted in casings 7 which are in direct communication with the pressure pipe line 2 so that the pressure in the reservoirs and oil-ducts 3 of the cable is directly produced and maintained by the pressure prevailing in the pipe line. In a modified arrangement, communication between the pipe line and casing 7 is through a pipe containing a valve which is normally shut, but which opens to relieve the pressure in the casing when the pressure in the pipe line falls. Stop joints 5 are provided in the cable at the points where the expansion reservoirs are fitted, and, to prevent by-passing of the joint, the reservoirs have a central partition 9.

Non-conducting coverings for heat.-The walls of heat-retaining vessels are formed of spaced layers or windings 1 of corrugated fibrous material, particularly corrugated paper sheets, i.e. sheets of corrugated paper secured to a plain backing, the corrugations being broken down at intervals to form dead air cells throughout the walls. The bottom 6 of the vessel is formed of superposed disks of the same material, with an interposed layer 8 of asbestos or the like, and a loose plug lid 34, Fig. 6, is similarly formed, the disks, however, being contained within telescopic members 35, 38 so that they are compressed when the lid is pressed down on its seating 33. The walls may be protected by or covered with an outer paper or other casing 30, which is provided, with a spring bail handle 44 adapted to interlock with a spring bail handle 45 on the lid to hold the latter in position. The walls may be formed of a single sheet of corrugated paper wound into a spiral, the spaces between the windings being maintained by cords 3, Fig. 1, which are pressed into the material t'o break down the corrugations at the ends and thereby seal the air spaces. The wall is tapered at each end beyond these cords, and the ends of the sheets are covered by sheets 5 glued on, or are secured together by an adhesive adapted also to fill and close the ends of the corrugations. Packing-rings 32, Fig. 6, of cork or paper are fitted at the ends of the walls to provide a seating for the lid and to secure flat ends. A layer of asbestos may be interposed between the corrugated sheets of the walls. The disks in the bottom and lid may have depressions across the corrugations to form dead air spaces. The layers may be arranged with the corrugations face to face, or with the corrugations of one layer adjacent to the plain surface of the next layer, and the tapering ends of the walls may be compressed to close the air spaces. The inside of the container may be lined with paraffin paper 12 to render it waterproof.

Abstract: 965,615. Packaging-machines. PACKAGING FRONTIERS Inc. Aug. 23, 1962 [Sept. 1, 1961], No. 32401/62. Heading B8C. Flexible packages, which may be of tetrahedron shape, are formed by cutting a roll Fig. 8, of web material at intervals, forming each piece of web into a tube T round a mandrel 35 from which the tubes are removed by suction grippers 59 on a continuously rotating turret machine which successively seals the lower end of the tube, fills the tube, seals the upper end of the tube and discharges it on to a conveyer 67. Each station 55 of the turret machine has its own sealing and filling mechanism. The web may be of laminated paper and metal foil coated on one surface with polythene. Operation.-Rollers 15 draw the web to a cutting roller 19, a photo-cell 23 registering incorrect positioning of printing spaced at intervals on the upper surface of the web. Rotary dies 27 perforate the web which is then carried by endless conveyers 31, 33 between the mandrel 35 and a former 39. Further endless conveyers 43, 45 feed the tube forward, the longitudinal margins being heat-sealed along their inside faces at 41. After removal by the grippers 59 the tube is turned through 90 degrees by means of cam-operated rods 57, and a lower sealing head 3 closes the lower end of the tube before a filling nozzle N is lowered to discharge liquid into the tube. An upper sealing head 1 then closes to heat-seal the package at rightangles to the lower seal, the sealed package being discharged through an aperture 63 in the lower plate of the rotary machine. The sealing heads 1 and 3 may be parallel to one another to form a flat package, Fig. 9 (not shown). The packages may be made from a pre-formed tube.
