Abstract: 1,270,799. Battery supply systems. JOSEPH LUCAS (INDUSTRIES) Ltd. 30 Sept., 1969 [14 Oct., 1968], No. 48523/68. Heading H2H. A system comprising two batteries to be connected together comprises means whereby the connection between the batteries can only be made if the batteries are connected with the correct polarities. The system is applicable to motor vehicles wherein a slave battery may be connected to terminals 16, 17 to assist the vehicle battery connected to terminals 11, 12 when starting the vehicle engine. Each of the terminals 11, 12 comprise two parts 11, 11a; 12, 12a insulated from one another. When the vehicle battery is connected to terminals 11, 12 a relay 14 will be energized, to close contact 23, if the battery has a sufficient charge still remaining and if the battery is connected with the correct polarity so that diode 13 conducts. When the slave battery is connected to terminals 16, 17 the coil 22 of an electromagnetic contactor will be energized if the battery is connected with the correct polarity so that diode 24 is conductive. Energization of coil 22 closes contactor 21 to connect the batteries together whereupon a relay 32 is energized to open contacts 33 to insert a resistor 31 in the energizing circuit of coil 22, thus providing a relatively high pull-in current and a lower maintaining current for the coil 22.

Title: Improvements in or relating to transistor circuits

Filed: 1963-12-31
Abstract: 982,129. Transistor amplifying circuits. STANDARD TELEPHONES & CABLES Ltd. Dec. 31, 1963, No. 51337/63. Heading H3T. The invention relates to a transistor amplifier circuit utilizing transistors T1, T2 in cascade connection, i.e. with their emittercollector paths connected in series, so as to obtain a larger voltage output swing than can be obtained from a single transistor. The base of transistor T1 is biased by means of an emitter circuit resistor R3 and the base of transistor T2 by means of a potentiometer R4, R5 across the supply. In such a circuit there is the danger of the transistors being driven beyond their allowable emitter to collector voltage rating on peak input swings; this is prevented, according to the invention by connecting a diode D1 across the base to emitter path of the transistor T2. The diode is poled to conduct in the opposite direction to that path and is rendered conductive by means of a resistor R1 of high value connected to the supply line. The arrangement may be extended to use three or more transistors in series, the base of each of the transistors with the exception of the first being biased via a separate potentiometer. Capacitors may be connected between each base and earth in order to prevent overshoot on the occurrence of sharp large transcents in the input signal voltage.

In one embodiment a sleeve 26 is connected to a spindle 12 by a spigot 22 and has rings 14, 15 compressed between abutments on a spacer sleeve 10 and cones 18, 19 which are respectively fast with and threaded on the sleeve 26.

A split cylinder may be bonded to a coating of resilient material such as rubber. In a modification the rings are compressed between radial abutments on the sleeve and the shell. This arrangement may be further modified by providing the abutments on the sleeve only and compressing each ring by a nut screwed onto the sleeve. Alternatively the rings may be compressed by a single nut acting against one of the rings, a spacer sleeve with abutments being provided between the rings, and the sleeve having an abutment for the ring at its end opposite to the nut.

The solution rate may additionally be modified by use of a plasticiser. The polymer may be cationic, e.g. poly(ethylene imine), ethoxylated and propoxylated poly- (ethylene imine), poly(N,N,N-trimethylaminoethylmethacrylate methylsulphate), and homopolymers and copolymers of N,N-dimethylaminoethyl methacrylate; anionic, e.g. poly(acrylic acid), poly(methacrylic acid), poly(sodium vinyl sulphonate), copolymers of acrylic acid and copolymers of methacrylic acid; or non-ionic, e.g. dextrinised starches, poly(ethylene oxide), poly(acrylamide), poly(N-vinyl pyrrolidone) and poly(vinyl methylether). The cementitious matrix may be sodium silicate, calcium silicate, cement, concrete, mortar and gypsum. The calcium silicate matrix may be made from siliceous materials such as Portland cement, siliceous sand, quartz, diatomaceous earth, clays, silica gel and perlite and calcareous materials such as Portland cement, quicklime and slaked lime. Cellulosic fibres e.g. pulp, cotton, straw, bagasse, wood flour, hemp, and rayon may be included in the cementitious composition.

As applied to the process of films two identical dispensing devices are located sideby-side as shown, the measuring tank 13 being adapted to be filled with a developer solution from a supply tank 25 and the tank 14 with a fixing solution from a supply tank 28. In operation of the device in a photographic processing plant, the films fed into the plant maintain a motor-driven timing disc rotating so that, after a predetermined time, the disc actuates a switch which in turn actuates switches to start motor-driven pumps M1, M2 to thereby pump the developer and fixing liquids into the tanks 13, 14 respectively. When the liquids reach the levels 22, the switches S5, S6 are actuated by the floats 15 to switch-off the pumps; at this point the syphon action begins and the liquids in the tanks flow therefrom into trays below the legs 21 of the syphons. In order to vary the amount dispensed, adjustable displacers 17 are provided in each measuring tank; alternatively, the displacers may be replaced by sleeves mounted over the ends of the short legs 20 of the syphon so that the level 23 at which the syphon action is broken can be varied. In other modifications, the pumps may be dispensed with and the liquid fed into the measuring tanks by gravity or the liquid in the supply tanks may be pressurized. The tanks 13, 14, floats, syphons and displacers 17 may be made from a plastics material.
