[Also in Division B8] A machine for sucking gaseous material from a container containing a foodstuff and introducing therein a liquid (i.e. as a preservative) comprises a container conveyer means, liquid supply and gas removal means and a set of operating heads positioned above the conveyer means, each head being connected to the control liquid and gas removal means, wherein the container is positioned on the conveyer means, a portion of the operating head descends on to the container and a valve in the head opens thus allowing gaseous material to be sucked out of the container, this valve then shuts and another opens, allowing the introduction of liquid, the head finally lifting off of the container. A suitable machine is shown in Fig. 1 wherein containers are fed on to the revolving conveyer 8 and positioned under one of the operating heads. The above sequence of motions is carried out by a control means in the form of cams 63, 64 and 65. Gaseous material is removed from the container via the tube 29, and control liquid is supplied from the reservoir 13 via the tube 31.

Abstract: 1,257,209. Transistor amplifiers. BURROUGHS CORP. 20 Aug., 1969, No. 41576/69. Heading H3T.  A differential amplifier has two pairs of current amplifiers such as transistors Q1<SP>11</SP>, Q3<SP>11</SP> and Q2<SP>11</SP>, Q4<SP>11</SP> each pair being connected in cascade as shown and having a D.C. negative feedback path such as a Zener diode Z1<SP>11</SP>, Z2<SP>11</SP> from the collector to the emitter of that transistor Q3<SP>11</SP>, Q4<SP>11</SP> receiving the input A<SP>11</SP>, B<SP>11</SP> (the feedback being via Q1<SP>11</SP>, Q2<SP>11</SP>) and also having an A.C. path R1<SP>11</SP>C1<SP>11</SP> from Q3<SP>11</SP> emitter to Q4<SP>11</SP> emitter. The inputs A<SP>11</SP>, B<SP>11</SP> may be from magnetic store sense windings L1<SP>11</SP> L2<SP>11</SP> and the D.C. negative feedback operates as follows to compensate for input D.C. level variations and component variations: if, say, B<SP>11</SP> goes more negative, then Q4<SP>11</SP> collector goes more positive and so must Q2<SP>11</SP> base because of Z2<SP>11</SP>; thus Q2<SP>11</SP> collector current is decreased to oppose the attempted increase in Q4<SP>11</SP> collector current. A<SP>11</SP> being equal and opposite to B<SP>11</SP>, the opposite changes occur in Q3<SP>11</SP>, Q1<SP>11</SP>. If a rapid negative signal is applied to B<SP>11</SP> however, capacitor C1<SP>11</SP> effectively supplies current to Q4<SP>11</SP> to offset the negative feedback, and also applies the negative going signal at Q4<SP>11</SP> emitter to Q3<SP>11</SP> emitter to reduce the Q3<SP>11</SP> collector current (this is also reduced by the positive complementary input A<SP>11</SP>). Consequently Q1<SP>11</SP> collector current increases due to Z1<SP>11</SP> and supplies the capacitor current required for Q4<SP>11</SP>, so that effectively a positive A.C. feedback is achieved. A capacitor C2<SP>11</SP> suppresses h.f. noise and tendencies to oscillation. Resistors R7<SP>11</SP>, R8<SP>11</SP> and diodes D5<SP>11</SP>, D6<SP>11</SP> protect Q3<SP>11</SP>, Q4<SP>11</SP> from reverse voltages. Diodes D3<SP>11</SP>, D4<SP>11</SP> and resistors R15<SP>11</SP>, R16<SP>11</SP> constitute transient-minimizing gates, in which a normally negative bias D<SP>11</SP> is made positive when information is being written in the store, to prevent switching transients arising in coils L1<SP>11</SP>, L2<SP>11</SP> from reaching the amplifier. Multiple input windings with switches are mentioned.

Abstract: 1297998 Monitoring IC engine performance SNAM PROGETTI SpA 11 March 1970 [11 March 1969] 11773/70 Heading G1N Electrical transducers are used with an I.C. engine to monitor the pressure variations in a cylinder at detonation, and the time interval or angular displacement between ignition and top dead centre position. The pressure inside the cylinder is measured by a Piezo-electric element T, Fig. 1, the output signal indicating the general pressure variations and the high frequency variations which occur at detonation (IA) of Fig. 2. The latter are separated by a high pass filter 3 (4A) of Fig. 2 and fed to a gate 4. The pressure signal is also differentiated at 6 and the zero value, corresponding to the maximum pressure just before detonation, causes a monostable  multi-vibrator 7 to emit a pulse (3A) of Fig. 2, whose duration is made inversely proportional to engine speed by a link between the multivibrator and a tachogenerator 16, whereby the pulse duration corresponds to a constant angle of rotation of the engine, during which the detonations occur. The pulse is fed to gate 4, which passes the vibration signals to an integrator 13, the average value being shown at 5. The ignition voltage at spark-plug 14 is modified at 8 to a narrow pulse (5A) of Fig.2 which is fed to one input of a bi-stable multivibrator 9 whose other input is the pulse from multi-vibrator 7. The output from 9 is therefore a pulse (6A) of Fig.2 whose duration represents the time interval from ignition to maximum pressure in the cylinder. This pulse is measured at 15 and also fed to gate 11 which controls a counter 12 fed with a pulse train from a further tachogenerator 10, whereby the counter 12 measures the angular displacement between  ignition and top dead centre.
