Filed: 1972-10-23
Abstract: 1377630 Ship propulsion ENERGLYN RT HON LORD 23 Oct 1972 [23 Oct 1971] 49339/71 Heading B7V [Also in Divisions B1-B2 and F1] A device capable of pumping, stirring, autogenous grinding or mixing comprises a hollow body 1 having an aperture 2 at or adjacent one end, the cross-section of the body at right angles to the longitudinal axis increases from said one end to a maximum where the body has a plurality of apertures 5 therein, the cross-section then decreases to a closed end and there are means 4 for rotating the body about said axis. The body may take the form as shown in Figs. 1, 2 and 3. Fig. 4 shows two devices mounted in series for moving powders or sludges from a depth. A sieve 7 can be used to rid liquids of unwanted constituents. The devices may also be mounted inside a pipe to act as a conventional lift pump. Alternatively the device can serve as a means of propelling ships or boats, or in industrial processes involving the production of fine powders, the mixing of powders, the formation of fine mixtures such as paint, emulsions, dyes and the removal of sludges or slimes from tanks and cess pits.

Title: Device for cold starting internal combustion engines
IPC: F02D41/06
Filed: 1968-10-18
Abstract: 1,205,848. Electric control systems. ROBERT BOSCH G.m.b.H. Oct.18, 1968 [Oct.21, 1967], No. 49426/68. Addition to 1,164, 747. Heading G1N. In an electronically controlled petrol injection system for an internal combustion engine as claimed in the parent Specification, the astable multi-vibrator 24 for applying additional triggering pulses to the mono-stable multi-vibrator 28 for supplying an additional amount of fuel for cold starting includes a unijunction transistor 120 where base electrodes B1, B2 are connected to a starter switch 100 and whose control electrode E is connected to a charging capacitor 122 which is charged up to the triggering voltage of the transistor 120 in dependence upon the temperature of the engine as detected by N.T.C. resistor 130. When triggered, capacitor 122 discharges and a negative voltage jump appears at the base of transistor 66 thus blocking transistor 66 to produce an additional pulse. When the engine temperature reaches a predetermined value which can be set by resistor 127, a diode 125 prevents the capacitor 122 charging to the triggering voltage of the transistor 120. A switch 117 is coupled to a diaphragm box connected to the intake manifold of the engine and is closed when the engine is not running but opens when the pressure in the manifold drops to a fixed value or when a fixed minimum engine speed is obtained.

Title: Bi-stable trigger circuit
Inventor: HOURIE JOSEPH KIRKLEY
IPC: H03K3/288
Filed: 1967-11-01
Abstract: 1,242,855. Bi-stable circuit. J. K. HOURIE. 1 Nov., 1968 [1 Nov., 1967], No. 49658/67. Heading H3T. [Also in Divisions B3 and G1] A bi-stable such as T1, T2 drives a load such as T3, T4 through isolating means such as D1, D2 and is adjusted by a variable resistor VR1 so as to exhibit no tendency to preferentially assume one or other state upon connection of a periodic supply, provided that an input signal applied to R5, R6 has a predetermined value such as zero; and the circuit assumes one or other stable state if the input changes in one or other direction from the said value. The supply is continually interrupted by an astable switching circuit T5, T6 or by a switch (S, Figs. 1, 2, not shown) so that when the input signal changes the circuit responds without hysteresis. The output of the astable circuit is connected, at A, to the collector resistors R1, R2 of the bistable, and transistors T3, T4 operate respective lamps L1, L2. Capacitors C1, C2 ensure that one lamp or the other remains on in response to a continuing input signal, despite the continual disconnections of the power supply. In the absence of an input signal, neither lamp is lit. Alternative adjusting means for balancing the bi-stable are a variable resistor (R6, Fig. 2, not shown) between T1 base and the supply, there being a fixed resistor (R5) between T2 base and the supply; and a potentiometer (VR1, Fig. 4, not shown) connected between the resistors R1, R2 at their ends remote from the collectors, and having its wiper connected to the astable circuit output which constitutes the power supply (Q5, Q6). The power supply to the bistables may be derived as an interrupted supply, alternatively, from an A.C. source (Fig. 5, not shown) and an unsmoothed bridge rectifier. The bi-stable circuit, as applied to lathe control (Fig. 6, not shown), is used as an amplifier comparing the outputs of two potentiometers VR1, VR2 responsive respectively to chuck and tool movement; by co-ordinating these movements to maintain neither lamp L1, not L2 on, an operator is able to accurately control the cutting of a screw-thread. A light-sensitive embodiment (Fig. 8, not shown) uses a photo-transistor (T1) in a bridge circuit whose unbalance is measured by the bistable. An alternative bridge balancing arrangement is also described for measuring resistances (Fig. 9, not shown). The bi-stable may be used also as an amplifier (Fig. 10, not shown).

[Also in Divisions D1 and H2] To tension a belt 13 of a belt drive from an electric motor 17, a jockey pulley 24 on an arm 23 rigid with the motor casing is pressed against the belt by the reaction torque on the motor casing, which is rotatably mounted on bearings 20. Stops 22 limit the rotation of the casing, e.g. to 120 degrees. As shown, a twospeed motor 17 drives a washing machine drum 2 via a two-speed belt gear 14, 13, 9 and a belt reduction gear 9, 8, 6. For pre-wash, wash, and rinse operations, the motor is run at low speed with periodic reversal of direction, the pulley 14 being at its minimum effective diameter (Fig. 1b, not shown). For spin-drying, the motor speed is increased by programmed pole changing, centrifugal weights 19 moving one flange 18 of the pulley 14 to the maximum effective diameter position shown. The jockey pulley 24 is axially free on its shaft 26, or may have a groove appreciably wider than the belt width (Fig. 5, not shown).

Abstract: 1397760 Multiplex pulse code signalling SIEMENS-ALBIS AG 17 Nov 1972 53152/72 Heading H4L A p.c.m.-t.d.m. exchange (V si O, Fig. 1, not shown) which clocks received data into a buffer store PS, Fig. 3, at the received data bit-rate and clocks it out at its own bit rate, uses socalled blind bits and inhibition of the local clock TG to correct undesired pulse-frame shifts arising from extraneous causes. The start-bits I, II, III, Fig. 2a, of respective data frames from other exchanges V st 1-3, when formed to arrive during the time # preceding the start-bit # of the receiving exchangedata-frame, are appropriately delayed by the buffer PS and read out by the local clock TG. If however they arrive in the interval γ and require a delay of less than this minimum value γ, then the exchange inserts blind bits to delay #. Correction for undesired frame shifts may be effected by similar use of these blind bits. If however the frame shift exceeds the maximum buffer storage time # (which in practice also equals T) then inhibition of the clock is effected, preferably for a period of ¢ #. Each blind bit is generated by a control circuit BB in response to coincidence at UBB of a received start bit ae from a synchronizing word detector SE connected to the incoming line, and a signal from bi-stable CA or AP which generate outputs respectively corresponding to the γ and r periods. Counters Zp and Zpc and dividers B, K control these bi-stables in response to the clock TG. The clock is inhibited by a circuit SS for a period such as ¢#, determined by a delay therein, when the circuit SS senses no received start-bits ae from SE during the # period as represented by the output of another bi-stable PA.
