Title: Improvements in or relating to digital scale changing
IPC: G01C11/00
Filed: 1969-10-07
Abstract: 1242770 Selective signalling; scaling by counting H DELL FOSTER CO 7 Oct 1969 [8 Oct 1968] 49136/69 Headings G4D D7X D6Y D6C1 and D6C2 Each pulse from an encoder 35, e.g. representing an increment of movement of a cursor manually traced over a line on a map or photograph, triggers a clock generator 37 to supply a train of pulses, e.g. 9 to scaling counters 39-41 via gates 42-44. The counters are pre-set manually to a selected scaling factor, e.g. 1, encoder pulse is equivalent to 736 distance units, and after receiving the corresponding number of pulses the counters close their respective gates 42-44. Thus in the example chosen, for each encoder pulse, 6, 3 and 7 pulses are supplied to counters 45, 46 and 47 which form an accumulator. The counters may step in either direction depending on the direction of movement of the cursor, and every 10 the clockpulse may be used to initiate carry propagation between the counters (carry look-ahead may be provided). The apparatus is applicable to area measuring systems in which an x-direction value is added to an accumulated total for each equal increment of movement in the y-direction.

Title: Arc welding apparatus
IPC: B23K11/26
Filed: 1963-12-13
Abstract: 1,056,110. Control systems for arc welding systems. PULSE ARC WELDER CO. Dec. 13, 1963 [Feb. 19, 1963], No. 49446/63. Heading H2H. [Also in Divisions B3 and H1] In arc welding apparatus, a store of energy is discharged between the workpieces through an auxiliary circuit which produces a high potential to initiate the arc and a main circuit which produces a relatively low potential to sustain the arc, and an electromagnetic actuator causes the workpieces to be brought together as the arc discharge occurs. The condenser 70 of a bank 20 of condensers of various capacities selected by a switch 74 is charged from an A.C. supply 24 through a half-wave diode rectifier 36. The weld is effected by closing a switch 64 whereupon a condenser 66 discharges to momentarily operate a relay 60. The condenser 70 discharges through two parallel circuits, the first comprising the primary 98 of a split-cored transformer 82 and the second passing through an auto-transformer 78, the secondary 96 of the transformer 82 and the wires 10, 12 to earth. The primary 98 and secondary 96 have resonant frequencies of the order of 5-10 megacycles and upwards of several hundred megacycles respectively so that a fleeting pulse of high voltage high frequency current is produced to ionize the gap between the wires 10, 12 and the resulting arc is briefly maintained by current passing through the second circuit. Meanwhile discharge of a condenser 188 produces a pulse to energize the coils 160, 162 of the actuator to bring the wires 10, 12 together. An additional circuit consisting of a condenser 106 and a winding 108 on the transformer 82 may assist the initial pulse. A condenser 114 and a winding 112 de-magnetize the core of the transformer 82 when the welding cycle is completed. Should an operator be touching the electrodes, the resonant frequency of the primary 98 is reduced so that the initial pulse is slow to build up, an arc is not established and the discharge through the second circuit in view of the high resistance of the gap leaks through the section 94 of the autotransformer 78 to earth. In a modification, the coils 160, 162 are located between the secondary 96 and the wire 10.

Abstract: 1387934 Gearing YOKOGAWA ELECTRIC WORKS Ltd 27 Oct 1972 49578/72 Heading F2Q [Also in Divisions G1 and B6] In apparatus for recording on a chart values of a parameter (e.g. temperature) determined at a plurality of separate sources (see Division G1), a frame F which comprises two relatively pivotal parts 3, 4 is supported on a continuously rotating shaft 2 by a cylindrical member 5 encircling the shaft 2 and passing through plates 51, 52 attached to the frame, the cylindrical member 5 being provided with cam plates 57, 58 and with end rings 53, 54 which support roller bearings 55, 56 engaging a groove 2a in the shaft 2 and thereby ensure rotary movement of the cylindrical member with the shaft 2, A marking wheel 8 is fixed to a driving shaft (6) (Fig. 6, not shown) to which an inking pad 10 is drivably connected and the shaft (6) at its end opposite the wheel 8 is provided with a plate 7 having at its periphery rods extending parallel to the axis of the plate 7. These rods are engageable with a projection 58b from the cam plate 58 so that the wheel shaft 6 is caused to rotate intermittently with continuous rotation of the shaft 2. The shape of the cam plate 57 is such as to allow tilting of the frame part 4 relative to the part 3 for lowering of the inking wheel 8 into engagement with an underlying chart only when the shaft 2 is in a predetermined rotary position, the inking pad being so supported by a tiltable plate 93 that its engagement with the wheel 8 only occurs when the latter is engaged with the chart.

Title: Packaging material into individual pouches
IPC: B65B9/087
Filed: 1970-10-20
Abstract: 1334242 Packaging in pouches CLOUD MACHINE CORP 20 Oct 1970 [25 Feb 1970] 49772/70 Heading B8C In a packaging machine, a longitudinally folded web is transversely sealed to form a series of pouches which are distended prior to filling by moving adjacent transverse seals towards each other and by lifting the bottom of each pouch, the filled pouches then being sealed, severed from the web, and deposited in a shipping container.  Web folding and transverse sealing, Fig. 2.-A web 22 is drawn from a spool 23 by a drive roller 26 and is passed through a folding plow 28. The folded web is then pressed by a vertical roller 129 against heated lands 33 carried by a rotary drum 126 to form transverse heat seals 34. The plow 28 is free to pivot about a vertical axis and is vertically adjustable. The lands 33 are so formed as to form a spout-like portion in the pouches (see Fig. 6). A rotary blade 148 which co-operates with inserts on the lands 33 forms slits 143 in the pouches to facilitate subsequent opening of the filled and sealed pouches. Bag distending and filling, Figs. 3 and 8.-The folded and transversely sealed web is fed to the arcuate run of a driven endless chain 161 and is gripped between rollers 169 and members 166<SP>1</SP> carried by the chains 161. The spacing between the members at the arcuate run of the chains 161 is equal to the spacing between the seals 34 and hence as the chains enter their linear run the seals 34 are moved towards each other. A driven disc 192 carries rod members 194 which engage and lift the bottoms of the pouches. Also, air is directed into the pouches from nozzles 44. The distended pouches are then carried past a filling station 43 which comprises a plurality of nozzles 203 carried by a wheel 201. The nozzles are sequentially fed with liquid by a pump 223 and each nozzle is, after filling a pouch, connected to a vacuum source (not shown) to prevent spillage. In a modification (Fig. 14) the feed passage to each nozzle includes a resilient tube (241) which is compressed during filling but is allowed to expand after filling. During filling the pouches are tilted by a plate 251 to prevent splashing.  Pouch sealing and severing, and packaging of closed pouches (Figs. 3 and 4).-The filled pouches are next urged against a heated plate at a sealing station 49 to close the pouches. The series of filled and sealed pouches are then rotated through 90 degrees by rollers 52, 53 and severed from the web by a rotary cutter 57. The individual pouches drop into a shipping container and are counted by a photo-cell 63. When a predetermined number of pouches have entered the container 62, a baffle 64 is pivoted to collect pouches whilst the filled container 62 is replaced. Defective pouches are deflected away from the container 62 by a pivoted plate 61.

Abstract: 1480889 Washing food trays KUPPERBUSCH AG 4 Dec 1975 [6 Dec 1974] 49836/75 Heading A4F [ Also in Division B8] Carriers 4 on food trays 5, are discharged from the latter by being floated to the surface when the trays are conveyed into water in a tank 1. The carriers on the surface of the water are then subject to the action of laterally directed water jets (9), Fig. 3 (not shown) which direct them on to a conveyer 11. Further jets (10) assist in this operation. The carriers pass upwardly from the conveyer 11 to a conveyer 13. They are held from lateral deflection while on this conveyer by the spikes of a wheel 15, whilst yet further jets (14) cause discharge of food particles 16 in the carriers, on to an upwardly sloping conveyer 17. This conveys the food 16 to a container. (For Figure see next page)

Abstract: 1,094,355. Constant volume amplifier. MULLARD Ltd. Dec. 9, 1964, No. 50107/64. Heading H4R. A constant volume amplifier comprises an input buffer stage 13, and two amplifying stages 19 and 25 the output of transistor 30 of stage 25 being rectified in transistor 32 and applied via an emitter follower circuit, comprising transistors 38 and 39, and a logarithmic control circuit 22 to the base of bottomed transistor 20 which is connected as a variable shunt attenuator on the input of the amplifier. The rectified output voltage is also applied from point 50 of the emitter follower stage to a memory circuit 43, the operation of which is controlled by a speech detector 44 and a trigger circuit 45, to supply a control signal to the shunt attenuator during pauses in the speech signal applied to the amplifier. The method of operation of the memory circuit is that speech applied to the detector 44 causes the setting of trigger circuits to a first state which enables amplifier 46 on the memory stage input and disables transistor 47 on the memory stage output so that the control signal from terminal 50 is applied to the memory stage to appear as a quantized signal on the output of amplifier 55. If the speech signals on the input terminal 11 cease, trigger 45 is operated to a second state in which amplifier 46 is disabled and transistor 47 enabled so that the memory unit 43 holds its last known valve and feeds this signal through transistor 47 to the emitter follower circuit input to hold the last assumed value of shunt attenuation of the transistor 20. The speech detector may be of the type described in Specification 1,094,357 and the quantizer of the type described in Specification 1,094,356.

Filed: 1965-12-03
Abstract: 1,097,209. Central systems for electromagnetic devices. W. BINDER, [trading as BINDER MAGNETE KOMM GES.]. Dec. 3, 1965 [Dec. 21, 1964; April 5, 1965], No. 51467/65. Heading H2H. A circuit for the rapid energization of an electromagnet, such as a lifting magnet, comprises means whereby the magnet is energized initially at a high value and subsequently the energization is reduced to a lower, normal value. An electromagnet 51 is energized from a three-phase transformer 10 initially by way of four thyristors 21-24 and subsequently by way of thyristors 21, 22 only, the secondary windings I, II, III being connected so as to produce voltages in quadrature and the winding of phase I having a larger number of turns than the windings of phases II, III which have equal numbers of turns. The firing, potentials for the rectifiers 21-24 are produced by the circuit shown in Fig. 4. A high frequency potential 120 is developed from the threephase supply by means of a relaxation oscillator and this potential causes firing signals to be applied to rectifiers 21, 22 by means: of a transformer 72. Upon initial switching on of the magnet 51 the current i flowing therein causes a voltage drop across the resistor 62 so as. to cause charging of a capacitor 64. During this time a diode 84 is conductive and the impedance of transformer 80 will be low, thus: permitting firing signals for the rectifiers 23, 24 to be developed by the transformer 71. When the capacitor 64 is fully charged the diode 84 is blocked, whereupon the impedance of transformer 80 becomes high, thus preventing the development of firing signals for the rectifiers 23, 24 by the transformer 71.

Abstract: 1507220 Radar display; cathode-ray-tube circuits THOMSON-CSF 23 Dec 1975 [27 Dec 1974] 52677/75 Headings H4D and H4T A composite display of radar video signals and vector/alphanumeric symbols is produced on a colour C.R.T. of the penetration type. Raw video signals representative of a radar map are fed to a scan converter circuit which processes them into X-Y Cartesian co-ordinate format. The processed signals are analysed on the basis of selection criteria, then allocated to storage locations according to the analysis result. The C.R.T. beam is scanned in two modes alternately. One mode is a line-by-line scan during which the radar X-Y video signals are read out of store and displayed in a plurality of shades of at least one colour, the shades being associated with respective ones of the storage locations. The other mode is a "random" scan during which symbol video signals from a symbol generator are displayed in at least one colour. In the embodiment described the raw radar video signals are derived from panoramic scanning radar and are in B-scan or E-scan format. The storage of the radar signals, in digital form, is at a rate dependent on the radar p.r.f.; but the read-out can be at a faster rate. The selection criterion may be altitude or range. Thus in one display example, radar targets below a given altitude are shown in one colour while those above are shown in a second colour. In a second example, all targets are shown in one colour, but in shades associated with different ranges. The store typically has a capacity enabling each dot of a 320-line, 320-dots-per-line display frame to be coded on three bits. For the first display example, one bit denotes colour and the other two bits represent four levels of the video signal. For the second display example, the three bits represent eight levels of the video signal. The display colour is determined by the accelerating voltage applied to the C.R.T., switched as necessary. The radar data are displayed over a central part of the C.R.T. screen. The symbols, relating to, e.g. navigational or weapons systems, are displayed at left and right edge parts of the screen. The lineby-line scan comprises sweeps alternately up and down the screen, with horizontal stepping of the C.R.T. beam between successive sweeps. Successive frames may be interlaced. A change-over switch enables the display of signals from a TV camera instead of the radar video signals.
