Title: Data handling system
IPC: G06F1/10
Filed: 1974-10-29
Abstract: 1459819 Data processing system INTERNATIONAL BUSINESS MACHINES CORP 29 Oct 1974 [26 Dec 1973] 46679/74 Heading G4A [Also in Division H4] A data handling or processing system includes a central unit and a number of other units each arranged, in response to a sequence of timing signals, to perform a sequence of operations, each of the other units including an individual timing circuit generating an appropriate single sequence of timing signals in response to an input signal and generating a "DONE" signal on completion of the sequence, and the central unit including means to issue input signals to selected ones of the other units to cause them to perform their sequences of operations and means to prevent the issue of further input signals until a "DONE" signal has been received from each of the selected other units. Timing signal generation.-Each unit, including the central unit, has a circuit, Fig. 2 (not shown), for generating a sequence of timing signals. The circuit includes a series of latches (A, B, C) which are set and reset in a timed sequence (which depends on circuit delays) in response to an input signal (DO). The output of one of the latches is fed to a delay line formed of a cascaded series of inverters and further logic circuits, controlled by additional control inputs (L, M), selectively connect various taps along the delay line to the latches to introduce a delay in the timed sequence of signals. System.-The central control unit, Fig. 5, includes a timing circuit 80 which produces a series of timing signals to gate a control word from a store 81 to one of the registers 88, 89. The timing sequence then stops and part of the control word sends "DO" signals to selected other units to activate them. As each activated unit finishes its operation it returns a "DONE" signal to the central unit where it is compared, 95, with mask signals. When all activated units finish their operations a positive comparison produces a "NEXT" signal to advance the central unit timing circuit and extract the next control word which is addressed via line 100 by its predecessor. An example of one of the other units is shown in Fig. 4 where data is successively gated into a logic unit 69, and result data gated to an output in response to clock signals A, B, C (only A and C being used), a "DONE" signal being produced when the result data is produced. The clock circuits may be formed in the same integrated circuit chip as the unit to which they belong. The sequences of operations in each of the units may include an error check operation, detection of an error causing the central unit to reinitiate the same sequence of operations (retry).

Title: Control system for indirect heat exchanger
IPC: F17C7/00
Filed: 1973-10-08
Abstract: 1441299 Fluid heating arrangements CLARKE CHAPMAN Ltd 8 Oct 1974 [8 Oct 1973] 46839/73 Heading F4S A fluid such as natural gas at high pressure, crude oil or fuel oil, flowing in a line 10, is heated in an arrangement comprising a duct 2 for said fluid, immersed in a body of an intermediate fluid (e.g. water) itself heated by a heater such as a burner 4 discharging its combustion products through a flue 3, the arrangement including also a by-pass for the duct 2 controlled by a valve 24 in response to a change in a parameter of the heated fluid downstream of the by-pass. The intention is that the fluid, before passing to a device such as a pressure reducing valve 18, has been heated to a sufficiently high temperature as predetermined by a thermal sensor 26 located downstream of the by-pass. The sensor 26 controls the valve 24 to direct move or less of the fluid stream 10 through the heater 2 as necessary, and may be responsive to the temperature, pressure, or mass flow of the heated fluid, or to any combination of these characteristics. The temperature of the intermediate fluid is maintained at a constant value by the sensor 16 controlling the fuel supply to the burner 4. When appropriate, the burner fuel supply may be tapped from the line 10 of fluid to be heated. The tapped-off fluid may then be preheated by the intermediate fluid before being supplied to the burner. A number of the heat exchanger assemblies may be interconnected either in series or in parallel.

Abstract: 1,209,303. Injection moulding. D. STERN. 23 Oct., 1967 [24 Oct., 1966], No. 47668/66. Heading B5A. Injection moulding apparatus for producing a succession of similar articles, e.g. car rear lamp lens, comprised of a plurality of different plastics materials, e.g. of different colours or compositions, includes a fixed platen 12 supporting a mould half 23 having differently shaped mould cavities 20-22 supplied respectively by injection cylinders 17-19 fed by hoppers 13-15, and a platen 25 which slides on bars 24 and supports a rotary core carrier 27 with four identical cores 28 equally spaced circumferentially about its rotary axis. A motor 29 indexes the carrier through angles of 90 degrees to bring three of the four cores into line with a mould cavity at each injection station whilst the fourth core lies at a cooling and discharge station. The mould parts are brought together by a ram 30. The injection cylinders are axially adjustable relative the mould cavities to bring their nozzles into engagement therewith, and they also may be adjusted vertically and swivelled about vertical spigots. At the first injection station the cylinder 17 injects a clear plastics material into the cavity 20 and on to the core, following which the carrier is retracted and indexed to convey the partial moulding on its core to the next station where the mould cavity 21 receives it and is supplied with a red plastics material superimposed on the first; the retraction and indexing re-engagement of mould parts is repeated, and at the third station an amber material is injected into the cavity 22, so that a three-colour lamp lens is produced. At the fourth station the lens is cooled and removed from the core. Each of the four stations are operated simultaneously. An embodiment is described having four identical core members which come, in turn, into engagement with three differently shaped members located in cavities in the stationary mould part. An automatic control system for the machine is described.

Title: Intruder or vehicle theft alarm system
IPC: B60R25/10
Filed: 1974-11-07
Abstract: 1475758 Vehicle theft alarms; intruder alarms INTERNATIONAL DETECTION PROTECTION 7 Nov 1974 [7 Nov 1973] 48293/74 Heading G4N An alarm system comprises three spring blade or reed switches actuable by application of a magnet, one switch ILS1 being arranged to energize the system, a second switch ILS2 arranged to de-energize the system and a third switch ILS3 located adjacent the de-energizing switch ILS2 arranged to set off the alarm if a magnet is brought within its proximity by an unauthorized person. The invention is applicable to vehicle theft alarms in which the unwanted occurrence is sensed by means of a toroid 1 detecting change in current from the vehicle battery or in the mains wiring of a building. The system is energized by bringing a magnet into proximity with ILS1 so that relay R is energized and contacts r1 arranged to switch the rectified output of toroid 1 to transistors T1 ... T3. If a load should be placed on the battery, e.g. by opening a door, a signal is amplified by T1 ... T3 and turns on Th1 which allows a multivibrator T6, T7, having a period of 0À5-1 sec., to oscillate. This provides low frequency pulses to T8 which energizes relay A, contacts a1 ... a3 of which intermittently energize the hooter, headlights and wireless receiver. This action continues until C1 has charged, when T4, T5 and Th1 will be turned off. C4 and T9 prevent the change in current from the batttery, as detected by toroid 1 from re-sounding the alarm. C4 prevents the alarm being initiated by current drawn by the vehicle clock. The alarm may be stopped by closing ILS4 by means of a handheld magnet which is left in position until C1 has charged. Nullifying by initiated person.-When the driver returns to the vehicle he applies the magnet to ILS2 which releases relay R and nullifies the system. If an unauthorized person, having seen the driver de-energize the alarm system by means of the magnet applied to ILS2, attempts to apply a magnet he is likely to energize ILS3 thus setting off the alarm.  Modifications.-In Fig. 3 (not shown) relay R is replaced by a further thyristor. A tenth transistor and third thyristor are also included to immobilize the ignition coil.

Abstract: 1,159,958. Hypodermic syringes. S. GRANT. 14 March, 1967 [15 Nov., 1965], No. 48443/65. Heading A5R. A hypodermic syringe has a plunger 10 for driving liquid from an ampoule 15 through a needle 16 to effect injection, a spring 14 for driving the plunger 10 on its injection stroke, a piston 12 coupled to the plunger 10 and movable within a cylinder 13, and a manuallyoperable valve 25 for controlling the flow of damping fluid from the part 23 of the cylinder in front of the piston to the part 22 of the cylinder behind the piston to allow controlled advance of the plunger 10 under the action of the spring 14. In the embodiment illustrated in Fig. 1, plunger 10 is connected by shaft 11 to piston 12 which is situated in oil-filled cylinder 13. Fitted to the piston is a one-way valve comprising spring 18 and valve plate 19 which closes the ends of channels 17 passing through the piston to prevent flow of oil from first compartment to second compartment 22; on pressing the plunger inwards to cock the syringe, however, the valve allows flow of oil in the reverse direction and hence allows free inward motion of the piston. The syringe is fired by depression of button 24 and integral valve block 25 as far as .stop 26 against the action of biasing spring 25' to allow oil to flow from first compartment 23 to second compartment 22 via channel 29, channel 27 formed in the valve block, and channel 28, thereby allowing the actuating spring to drive forward the piston and plunger to force liquid from ampoule 15 through needle 16. The ampoule is enclosed by holder 20 detachable at position 21 to allow the ampoule to be inserted and the plunger to be pressed inwardly. A constrictor valve, for example adjustable screw 30, may be situated in one of the passages connecting the two compartments to control the velocity of the piston when the syringe is fired. In a modification, the non-return valve may be formed by a cup-shaped seal attached to one face of the piston. In the embodiment illustrated in Fig. 2, the one-way valve fitted to the piston is omitted, the manually-operable means being coupled directly for example by plunger 34 moving in a hydraulic cylinder formed by oilfilled chamber 35, to a non-return valve to open the valve for passage of oil between the two compartments. The valve may be a needle valve having a fixed tapered needle 31 cooperating with a movable valve disc member 32 having a central orifice through which the needle extends, connected to a piston 33 which is a close fit on the stem of the needle, and being subject on both sides to the pressure of the oil passing through the orifice therein.

Abstract: 1455499 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 18 Nov 1974 [26 Dec 1973] 49785/74 Heading B6F  Type selection.  A print head carriage carries cams 54, 110 whose axial movement is converted into rotation and tilt respectively of head 20. Each cam has a circular groove with parallel loops. Respective cam followers 42, 112 can be moved, whilst the cams 54, 110 rotate to follow a selected one of the loops or remain in the circular groove. Only the following of one of the loops causes axial movement of the cams. Selection of the loop to be followed on the cam 54 is controlled by actuator 32 which can move rod 38 to cause axial movement of cam 28. This movement of the cam 28 causes assembly 58 to pivot about pin 60 and thereby steer the follower 42. Track 100 is shaped to facilitate this steering. Selection of the loop 171, 172, 173 to be followed on the cam 110 is by energization of coil 118 which releases latch armature 120 to let spring 134 pivot the follower 112. Both cams 54, 110 have their loops branching at points staggered along the groove so that selection of a groove is determined by timed energization of actuator 32 and coil 118. The tilt mechanism between the cam 110 and head 20 is as described in Specification 22197/74. Case shift. Case shift is achieved by solenoid 80 rocking support 76 and causing pinion 76 to engage the other rack.
