Abstract: 1,184,439. Fuel injection systems. C.A.V. Ltd. Oct.26, 1967 [Nov.11, 1966], No. 50654/66. Heading F1B. A device 11 for producing pilot injection similar to that of Fig. 2 of Specification 1, 060,181, is modified in that the restriction 22 through which the pilot fuel is forced by a piston 23 is a variable restriction formed by a spring-loaded piston 33 co-operating with orifice 22. The pilot fuel flows through orifice 36 in piston 33, the pressure drop across which orifices varies the position of the piston in relation to orifice 22. Orifice 22 discharges into a groove 18 through which the main fuel injection also flows when piston 23 opens the main orifice 20. The pistons 23, 33, slide in a bore 19 in a valve member 14 which lifts off its seat on the end of member 11 at the end of injection to permit fuel to return from the passage 13 leading to the injector to the pump 9. In Fig. 2 the valve 14 is replaced by a non-return valve 40 and a non-return valve 41 closes the end of piston 23 until the latter opens the main orifice 20. A restriction 44 in the passage 21 controls the rate of discharge of liquid from the space between the pistons 23, 33.

Abstract: 1374309 Protecting signal amplifiers; loudspeaker protection circuits PIONEER ELECTRONIC CORP 12 Nov 1971 [16 Nov 1970] 52767/71 Headings H3T and H4J [Also in Division H2] In a protective circuit for use in protecting a load impedance Sp from the application of an input signal including a D.C. voltage, a switching means 22 is responsive to a control signal for removing the input signal from the load impedance, a differential amplifier 21 includes two transistors T r1 , T r2  having their respective control electrodes connected to a common input terminal, one of the control electrodes is direct current connected to the input terminal and the other control electrode is connected to the input terminal by a condenser C for blocking D.C. and the arrangement is such that when the input of the protective circuit is connected in parallel with the load impedance L s  and an audio frequency signal is applied, the 'utput from the differential amplifier 21 is ineffective to actuate the switching means 22 whereas on application to the input of a signal including a D.C. potential the differential amplifier 21 produces a corresponding control signal to actuate the switching means. Normally the output line L 2  is at ground potential and the differential amplifier 21 is in balanced state. As the audio frequency output signal from the amplifier 1 is fed to both transistors T r1 , T r2  the differential amplifier remains in a balanced state. If the D.C. potential at the output L 2  varies such as due to some defect of the amplifier 1 then the differential amplifier 21 becomes unbalanced and operates a switching circuit 22 which opens the contact Y to protect the loud-speaker. The switching circuit 22 returns to its unoperated state after a few seconds to reclose the contact Y; if the differential amplifier 21 is still in the unbalanced state the contact Y is again opened to protect the loud-speaker. In a modification the power may be disconnected in which case the contact Y is not necessarily required.

Filed: 1972-11-16
Abstract: 1452067 Drop hammers HUNT BROS (OLDBURY) Ltd 15 Feb 1974 [16 Nov 1972] 52918/72 Heading B3H [Also in Division F1] A control system for a drop hammer of the kind comprising a tub 2, Fig. 1, slidable between guides 1, lifting gear 5, 7 for raising the tub, and means 6 for releasing the tub has at least one fluidic sensor 20A which produces a signal when the tub is in a predetermined position above its lowest position to release the tub. As described, three sensors 20A, 20B, 20C are provided, the position of each being adjustable so that the tub may be released at any one of three different heights. Operation of one or both of pedals 30, 31 determines which of the three sensors operates the tub release mechanism. A further sensor 20D activates the rollers 7 to raise the tub. Hammering continues as long as one of pedals 30, 31 is depressed and ceases with the tub in a raised position when both pedals are up. If the tub rises above the sensor 20C, a valve 77 is mechanically operated to switch off the drive and apply the clamps 6. To lower the tub after this has happened, a key-operated valve 81, Fig. 2, must be operated and then manually operated valves 89, 91. This causes the clamps to be disengaged and the tub to be lowered against the resistance of the un-driven rollers 7. Fig. 3 (not shown), illustrates the fluidic circuit which is actuated by the sensors. Each sensor produces a cone-shaped jet of air which is disturbed by the tub to produce a back-pressure in the control duct. The system fails safe if the air pressure falls below a predetermined amount or if the electricity supply fails. If either of the lines to pedals 30, 31 is damaged the tub will rise to position 20A and stop. Additional sensors may be added and the hammer may be programme controlled.

Abstract: 1336981 Digital computers BURROUGHS CORP 13 Nov 1970 [28 Nov 1969] 54201/70 Headings G4A and G4C The digital data processing system of copending Applications 54199/70 and 54200/70 is described with reference to its free field memory unit wherein operands and data segments can be of any size format. By this a requesting device, e.g. a central processor 10, an input/output module 18, or a memory extension controller 15, can extract or insert fields of data anywhere with the memory, a field being defined as a number of bits whose starting bit position may be anywhere within the memory. There may be up to sixteen memory modules 11 and sixteen requesting units, each memory unit being divided into a number of stacks, each stack having 8192 locations of 288 bits each. 256 bits are used for memory space and 32 bits for error coding making up four 72 bit words. Each memory module 11 has a field isolation unit 13 (Fig. 7, not shown) having a 144 bit fetch register which holds two 72 bit memory words, the first word being a copy of a memory word holding the present starting bit of a field and the second word being a copy of the memory word adjacent to the first word if the field is so long that it overflows from the first word. A requesting unit sends a memory control word to the unit 13, the word containing the absolute address of the starting bit of the field and the length of the field, and the address is used to access the two words. A shift register is used to position the words so that the starting position of the field is accessible, a buffer is provided together with parity checking for incoming and outgoing data, and an error register stores data on all other failures. Should the field length extend over more than two words then the next pair of adjacent words are accessed to accommodate the remaining field bits. Should a selected field overlap two memory storage units or modules then the requesting unit will have to generate a fresh memory control word. Provision for one bit error correction is mentioned, data transfer between the various units of Fig. 1, is in parallel and a priority circuit (Fig. 10, not shown) is provided to determine which requesting unit shall have access to one memory module.
