Title: Colour television camera arrangements
IPC: H04N9/04
Filed: 1971-11-09
Abstract: 1368946 Colour television EMI Ltd 9 Nov 1971 [10 Nov 1970] 53360/70 Heading H4F A colour television camera is provided with a source of bias light 5 and a filter 6 for producing a signal in the output of tube 4 indicative of the position of the scanning electron beam of tube 4. This may be used to register the scanning of the red, green and blue images on the tubes of a three-tube colour television camera or may be used to register the scanning beam of a one (or two)-tube line sequential colour television camera. In this latter case a horizontally (for a horizontal line scan of tube 4) striped colour filter 2 is focused on to the target of tube 4 and filter 6 superimposes on this pattern vertical red, green and blue stripes of different repetition frequencies. The output from tube 4 contains a superimposed signal indicative of the coloured stripe being scanned as each stripe of coloured light passed by filter 2 has superimposed on it a different frequency due to filter 6. This superimposed signal may be used to cause accurate scanning of one coloured stripe, or, if scanning is not accurate, it may cause the appropriate amounts of the undesired signals, which have been stored from previous lines, to be subtracted from the resultant signal. Instead of scanning each stripe separately, tube 4 may be arranged to scan a pair of stripes at each line scan, the red, green, and blue signals being derived by matrixing. For a three-tube camera filter 6 is monochrome and has lines of different frequency markings so that the line being scanned is identified by the superimposed frequency, and the position in the line is identified by the phase of the superimposed signal. To eliminate picture information at the repetition frequencies of the stripes of filter 6, the picture image may be de-focussed, or two overlapping picture images may be formed, with a separation equal to half the pitch of the red stripes of filter 6.

Abstract: 1411749 Rotary positive-displacement fluidmachines SMITHS INDUSTRIES Ltd 24 Nov 1972 [24 Nov 1971 8 Sept 1972 (2) 3 Jan 1972] 54678/71 41702/72 41703/72 and 72/72 Heading F1F An hydraulic gear-pump has its gears 18,19 lodged in a aperture 17 in a plate 12 of the housing, the plate being made of a softer material than the gears e.g. mild steel, cast iron or a sintered material. To minimize leakage from an outlet region 21 of the aperture to an inlet region 20 the aperture is initially slightly smaller in the vicinity of the gear teeth than is necessary to accommodate the gears, Fig. 3 (not shown), and is finished by the gears employed as cutters and being driven, singly or together, axially into the aperture while being rotated, Fig. 4 (not shown). Alternatively, the aperture is initially large enough to receive the gears and the latter are rotated while the plate is moved transversely of the axes of rotation so that the gear teeth remove portions of the plate adjacent the region 21, Figs. 5 and 6 (not shown). The said portions of the plate may be removed by the gears being rotated and driven axially into the aperture, Figs. 7 and 8 (not shown). As another alternative the aperture is again made large enough to receive the gears and its peripheral walls on either side of the region 21 are lined with moulded inserts made of a material softer than the gears e.g. copper-filled carbon, cast iron, a plastics material or Alzen (Registered Trade Mark), these inserts being finished to the required thickness by the gears, Figs. 9 to 11 (not shown). Coatings of e.g. a thixotropic epoxy-resin based paint, solder or white metal, may take the place of said inserts, Figs. 12 to 14 (not shown). The surfaces finished by the gears may be given a very thin coating of a resin-based material to render them smooth. Gears other than those comprised in the completed pump may be used to finish the aperture.

Abstract: 1,200,998. Moulding electrical strip conductors. REYNOLDS METALS CO. 18 Nov., 1968 [17 Nov., 1967], No. 54694/68. Heading B5A. [Also in Divisions B3 and H1] A method of making an electrical strip conductor comprises feeding a plurality of webs 12 of electrical conductor material to an extrusion device 14, extruding a curtain of plastics material 22 to one side of the webs to form a composite web, and thereafter slitting the composite web to form plastics coated webs having a plastics overhang along each marginal edge. Aluminium foil webs 12 are fed from rolls 10 and strip material 38 provides a support for the webs until the leading edges of the webs have had plastics material extruded thereon. Thereafter a knife 43 on a roll 42 cuts off the strip or it may be cut off by hand. Hot air is supplied through tubes 27 to overcome necking of the plastics, Fig. 8 (not shown), thereby maintaining a uniform distance across the web and keeping its edges thin. The coated sheet passes between a roll 24 and a chill roll 26, which solidifies the plastics material. Any suitable plastics may be used, e.g. polyethylene, polyesters, nylons, polyurethanes and polycarbonates, all of which tend to neck in polysulfones, acrylic resins or polyphenylene oxide. The composite web is preferably passed through the apparatus a second time to coat the uncoated side before being slit by the knives 28. The coated webs are wound into coils 46 and provided with terminal leads 54, 56. Heating dies may be used to fuse the overhang 50, 52 of the plastics material, Fig. 5 (not shown). Prior to coating with plastics, the strip conductor material may be pre-slit from a web of foil stock to the desired width.

Abstract: 1388877 Welding by fusion INSTITUT AVTOMATIKI MINISTERSTVA PRIBOROSTROENIA SREDSTV AVTOMATIZATSII I SYSTEM UPRAVLENIA SSSR 1 Dec 1972 55553/72 Heading B3R [Also in Division G3] An electrode 3 in seam welding apparatus is automatically guided to follow a butt 2 by a system in which the butt is detected photoelectrically by a device 1 connected to the electrode carriage. A projected light beam is reflected from the plates 4, 5 in the vicinity of the butt and imaged at an aperture which is scanned by a rotating slotted disc. The resulting output from the photo-cell is shown in Fig. 3a in which the first dip indicates the butt. This signal is shaped at 6 to produce Fig. 3b; T1 equals T2 when the electrode is centralized. The output of 6 is fed to two further signal shapers 7, 8 whose outputs are positive and negative pulses which are summed at 10 (the sum should be zero) and the result integrated at 11 to produce a voltage which is proportional to the electrode position error. This error signal is fed through a logic unit 14 to a controller 12 for an actuator 13 which positions the electrode carriage. A similar arrangement comprising a detector 16 and shaping and integrating circuits 17 ... 20 looks at the finished weld and overrides the first system, by logic 14, if the weld is incorrectly positioned. The detector 1 also determines the width of the butt and adjusts the welding current accordingly, by unspecified devices 21 ... 23. Also, the width of the weld, detected by 16, is used to control the feed speed of filler wire, by devices 24 ... 26. The action of all the control systems are suspended by an "inhibit" network 27 ... 30 in the event of spurious signals such as that constituting the second dip in Fig. 3a. Logic circuit 27 receives signals from the shapers 7, 8 (also from shapers 17, 18 by connections not shown) and from a "counter" 28. This determines when a dip occurs at a time when a plate is being scanned (i.e. during T2, Fig. 3b) and operates a flip-flop 29 controlling an inhibit switch 30. The circuits of the various devices are illustrated in Fig. 2 (not shown); in the main they comprise transistor bi-stable devices.

Title: Method of charging accumulators

Filed: 1974-12-31
Abstract: 1474137 Charging accumulators VARTA BATTERIE AG 31 Dec 1974 [2 Jan 1974] 56134/74 Heading H2H A method of charging a battery comprises a first phase in which constant current is supplied until a particular voltage is reached, and a second phase in which constant current pulses are applied, wherein the particular voltage is also detected in a pulse which detection causes the charging pulse to be terminated after a particular interval, and wherein during a pulse interval a second particular voltage is detected, lower than the first and in response initiating simultaneously a charging pulse interval and a shorter measuring interval, the accumulator voltage being detected at the end of the measuring interval and if it is below a third particular level below the second level a further charging pulse is initiated at the end of the pulse interval. Apparatus for effecting this method comprises a load LT across the accumulator and a control STL to control the current thereto. When charging is to commence, switch I is closed and constant, uninterrupted current is supplied via control STL. When the battery voltage reaches a level U1, the output of a first Schmidt trigger ST1 changes to positive and the rising flank of this output activates a timer to continue charging for a further period t 1  after which the current is terminated. The battery voltage will then fall to a value U2 and the trigger ST1 output will go negative the falling flank activating further timers simultaneously so that timing signals t 2 , t 3  are provided concurrently to the control STL, the longer interval t 2  determining the time between charging pulses and the shorter interval t 3  establishing an interval during which the accumulator voltage is measured against a lower value U3 set by a further Schmidt trigger ST2. This trigger develops an output if the accumulator voltage falls below U3 and in response a further charging pulse is developed by control STL when t 3  times out. If ST2 is not triggered, no further pulse is produced and charging ceases.
