Title: Meter with audible read-out
IPC: G01D7/12
Filed: 1971-11-29
Abstract: 1362395 Audible meter readout W VINTEN Ltd 23 Nov 1972 [29 Nov 1971] 55229/71 Heading G4H  The output of a meter is audible and electronically selected. The meter is preferably an ammeter or voltmeter and sound recordings may be on tape, disc or optical film. The embodiment described is a voltmeter with tape storage. The tape is an endless loop with recordings of the digits 0-9 and "point" on eleven of its twelve tracks. The set of recordings is repeated several times along the length of the tape and each recording is separated by a hole in the tape which permits light from a lamp 19 to fall on a photo-cell 20 when the hole is between them. The analogue voltage is applied to a manually operated range selection unit (22) which brings the voltage in the range 0-5 V. This voltage is converted to a BCD digital signal in analogue to digital converter 23 in which a pulse source is gated to a counter for the time that a reference voltage takes to rise from zero to the unknown voltage. The digital signal is passed to stores (" latches ") 28 and from the output of these to AND gates 29 and decimal point positioning circuit 31. This circuit receives a decimal point signal on one of lines P1-P5, inserts it in the correct place in the digital input according to the selected range and suppresses leading or trailing zeros. The output of this circuit is fed to stages 2-11 of programmable shift register 30. Readout is initiated by switch 24 generating a pulse from timebase 26, which pulse sets shift register 30 to stage 1, generates a signal at the outputs of latches 28 and sets bi-stable 25 to prevent further timebase pulses. Stage 1 of register 30 mutes AF amplifier 33 to prevent audible readout of part of a word. Movement of the magnetic tape produces a pulse from photo-cell 20 when aligned with a hole, and monostable 21 clocks the shift register to stage 2. This enables AND gate 29A and passes the value stored in latch 28A to decoder 36 where the binary signal is converted to decimal and thence to AF gates 37 where the tape head corresponding to the desired track is selected and fed to AF amplifier 33 and speaker 34. After each word, a clock pulse from the next hole steps the register, and the next word is transmitted. After stage II, the register resets bi-stable 25 so that the timebase can initiate another readout cycle. A visual display 38 may be provided via BCD to decimal decoder 37.

Filed: 1971-11-30
Abstract: 1406435 Fuel injection pumps BRYCE BERGER Ltd 28 Nov 1972 [30 Nov 1971] 55462/71 Heading F1A In a fuel injection pump comprising a plunger 10 reciprocable in a cylinder barrel 8 and having a helical fuel control groove 16 co-operable with a spill port 14, fuel leaking between the plunger and the barrel enters a circumferential groove 19 in the plunger and passes to low-pressure through a leakage groove 20 when the latter registers with a leakage port 21. The leakage groove 20 is positioned on the plunger so as to move out of register with the leakage port 21 prior to the fuel control groove 16 registering with the spill port 14. This ensures that the grooves 19, 20 are closed when leakage is occurring at maximum pressure, whereby some fuel traverses the groove 19 and lubricates the lower part of the plunger.

Title: Process for improving the filling capacity of tobacco
IPC: A24B3/18
Filed: 1972-12-13
Abstract: 1381203 Expanding tobacco BAT CIGARETTEN-FABRIKEN GmbH 13 Dec 1972 [17 Dec 1971] 57505/72 Heading A2C The filling capacity of tobacco is increased by subjecting tobacco with a moisture content greater than or equal to 19% to a reduction of pressure of at least 20% of the initial pressure with a pressure change velocity of at least 2% of the instantaneous pressure per second and fixing the condition of the tobacco by drying to a moisture content of less than 20%, the drop in pressure not being allowed to take place so rapidly that the cells are burst or puffed out because of interior overpressure. The pressure to which the tobacco is subjected may be reduced from atmospheric to below atmospheric with the drying preferably being effected at the lower pressure, or the pressure may be reduced from above atmospheric (e.g. 1.5 or 2 atmospheres absolute) down to atmospheric in which case the initial higher pressure must be built up gradually and/or maintained over a sufficiently long period to ensure saturation of the tobacco cells with gases before the pressure reduction is effected, Where the moisture content of the tobacco is relatively low, e.g. below 25%, it may be advantageous to increase the flexibility of the cell walls of the tobacco by raising its temperature to say 40-50‹C before effecting the pressure reduction.

Abstract: 1279840 Synchro indicating systems BENDIX CORP 12 Dec 1969 [19 Dec 1968 (2)] 60643/69 Heading G1N A synchro indicating system comprises an A.C. synchro transmitter and a D.C. synchro receiver wherein polyphase stator windings of the two synchros are inter-connected through phase controlled rectifier units which each include a pair of transistors. As shown an A. C. synchro 5 comprises a rotor 25 and a stator with 3 windings 28, 29, 30, each connected to a corresponding winding 50, 51, 52 of a D. C. synchro 15 with a permanent magnet rotor 55 controlling one digit of a numerical indicator. The connections are made through phase-controlled rectifiers 10, 10A, 10B each of which comprises a pair of back-to-back NPN transistors 37, 42 controlled through windings 13, 14. These are supplied with supply alternating current biasing a phase relationship with the supply E 1  at 11 as indicated by the dots. Assuming the rotor 25 to be in a position that the L.H.S. of E 2  is positive when the dotted ends are positive then during positive half cycles transistors 42 and 37A conduct and during negative half cycles all transistors are back biased off causing half-wave rectified signals with the polarity shown on the stator windings of syncro 15. If the rotor position is such that the R.H.S. of E  2  is positive when the dots are positive the polarity applied to the stator windings is reversed. Similar argument applies to the voltages E 3  and E 4  and the resultant as applied to the rotor 55 corresponds with the applied position of the transmitter rotor. Similar arrangement may be utilized to control two further indicators Fig. 1 (not shown). A further arrangement, Figs. 3 and 4 (not shown) utilizes phase-controlled rectifiers in only two of the three phase-to-phase stator-connecting lines. In this case each phase-controlled rectifier comprises a PNP and an NPN transistor in parallel.
