Abstract: 1,158,720. Gas lighters. MANSEI KOGYO K.K. 24 Nov., 1966 [26 Nov., 1965; 1 Feb., 1966], No. 52711/66. Heading F4F. [Also in Division H2] A liquefied gas fueled lighter comprises a fuel valve 50 extending through a fuel reservoir 3, a valve operating lever 9 pivoted at 8 to a chassis 7, a burner 25 connected with valve nozzle 6 via plastics tubing 43, piezo-electric assembly 12 adapted to be struck by a hammer 16a on the end of a lever 16b pivoted at 18 to chassis 7, manual sliding operating means 22 for the hammer, spark electrodes 26, 28 and springs 19 whose tension is increased and suddenly released by a cam-piece 23 during operation of the lighter. To operate the lighter means 22 are slid in the direction A which causes a roller assembly 35, 58 to rotate lever 9 counter-clockwise whereby its lower free end lifts nozzle 6 to open valve 50. Also wire return spring 38 is compressed and cam 23 contacts lever 16b to rotate it counter-clockwise and tension springs 19, Fig. 3 (not shown). Further sliding of means 22 causes cam 23 to contact an abutment 59 of the chassis whereby it is turned clockwise and releases lever 16b so that springs 19 contract and hammer 16a strikes a cap 13 on the end of the piezo-electric assembly 12. A spark between electrodes 26, 28 ignites gas issuing from burner 25. Positive electrode 28 is held in an insulator block 29 and is connected to the assembly 12 through a conductor 30 which contains a resistor 31. Negative electrode 26 is connected to the assembly 12 via the burner 25 chassis 7 and hammer 16a. After operation of the lighter the mechanism is returned to its original position by spring 38. Sliding means 22 are enclosed by a box-member 41 formed with a flame outlet 42 which is closed by a plate 37 when the lighter is not in use.

Title: Compensating for Vignetting in Television Systems.
IPC: H04N5/32
Filed: 1966-11-30
Abstract: 1,163,107. Television. SIEMENS A.G. 30 Nov., 1966 [1 Dec., 1965], No. 53718/66. Heading H4F. If, for example, as in the televising of low intensity X-ray pictures, use is made of a wide aperture lens to project the pictures on to the camera screen, the projected image will show a falling off of intensity at its periphery, i.e. vignetting, resulting in corresponding edge darkness in the reproduced picture. To overcome this, the invention proposes the integration of the television horizontal and vertical sawtooth voltages about the average valves thereof, to produce corresponding paraboli having maxima of either end thereof and the summation of the plurality of " horizontal " paraboli and the " vertical " parabola, occuring during one field to form a correcting signal which is added in synchronism to the video signal issuing from the television camera whereby the " horizontal " paraboli cause compensating brightening of each vertical edge of the reproduced picture, and the " vertical " parabola causes compensating brightness of each horizontal edge. To allow for variations of the brightness of the initial video signal, the correcting signal is amplified in proportion to the average brightness of the line being corrected. Since each corner of the thus corrected reproduced picture may be over-bright, blanking of the corrected signal is employed such that the reproduced picture is circular.

Title: Magnetic bubble circuit system
IPC: G11C19/08
Filed: 1973-11-29
Abstract: 1452931 Magnetic bubble stores; magnetic bubble computers MONSANTO CO 29 Nov 1973 [1 Dec 1972] 55316/73 Headings G4A and G4C [Also in Division H3] A circuit using magnetic bubble techniques comprises a number of bubble logic modules interconnected to form a closed bubble path. Each module is separately connected to a control unit which provides signals selectively controlling the modules. The circuit described, Fig. 1, has some of the modules, called line modules, connected to a memory comprising a number of bubble shift registers, called mark-time lines. The remaining modules perform arithmetic, logic, and control functions. Module O designates the line module via which an instruction stored in a mark-time line is to be obtained. In a fetch phase module O commands the control unit 10 to cause the required line module to pass the instruction via the closed bubble path to module 4. When the instruction is received module 4 signals the control unit to start the execute phase. Control fields in the instruction word are now routed to source and destination modules specified by the address fields of the word, and the circuit returns to the fetch phase. Modules 5-8 (described with reference to Fig. 8, not shown) perform addition and subtraction to provide all four arithmetic operations. The number system used during subtraction is two's complement with inverted sign bit. Each mark-time line, as indicated in Fig. 3, comprises 255 16-bit closed bubble loops 16 interconnected by bubble transfer paths 18 controlled by current on conductor 20 from the associated line module. Each line module contains one word length of the mark-time line. In addition to this length (the datum register) there are two address registers in the line module which store the address in the mark-time line of the word presently in the datum register and the address of a required word (the search address). The action performed by the line module depends upon the received control field referred to above, e.g. it passes the word in the datum register to the path connecting the modules, it passes a word received from the preceding module to the next, or it searches for the word specified by the search register contents. The control unit 10 includes serial-parallel bubble converters which respectively receive from module 0 an address field specifying the source and destination modules-in the fetch phase the destination module is always module 4. The parallel-bit outputs passes via bubble triplers to decoders which each provide a single bit output on the path 11 connecting the control unit to the relevant module. The serial-parallel converter, decoder and bubble bi-stables, triplers, &c. are described (Figs. 10-14, not shown).

Abstract: 1,173,438. Measuring displacements electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 9, 1966 [Dec. 16, 1965], No.55350/66. Heading G1N. [Also in Division H1] Changes in the length of a sample 2 Fig. 1 are measured by coupling one end to a piston 4 forming a wall of a resonant cavity 6 supplied with microwave signals from a reflex klystron generator 8 via an isolator 10 and attenuator 12. Changes in the length of the cavity alter its resonant frequency. The output from the cavity 6 is fed via directional coupler 16 to a second similar resonant cavity 20 and to a detector 22 whose output is fed to the Y axis of an oscilloscope 24, whose X axis scanning voltage is used to modulate the klystron frequency, so that the signal observed on the oscilloscope comprises a pulse a Fig.3 with inverted peaks b, c at the resonant frequencies of the two cavities. The piston 28 of cavity 20 is displaced by micrometer adjustment until the two peaks coincide, the displacement being equal to the change in length of sample 2. In a modification, the cavities 6, 20 are separately connected to the klystron 8 and the oscilloscope 24. In another embodiment Fig. 4, the frequency of the klystron 32 is automatically adjusted to the frequency of the cavity 6. Initially, with switch 38 open and 40 closed, the frequency of the klystron 32, reference cavity 20 and measuring cavity 6 are made equal, as described above. Switch 38 is then closed and 40 opened, and the output of detector 22 cover bonding to the difference in frequency of the klystron and cavity 6 is fed to device 36 which varies the porous supply 34 to the klystron whereby its frequency follows that of the cavity 6, and is measured by a microwave converter 42. The Specification describes the assembly of a sample 2 and measuring cavity 6 in a temperaturecontrolled flask located in e.g. the water of a swimming-pool reactor.

Abstract: 1,149,694. Moulding fibre-resin articles. WESTLAND AIRCRAFT Ltd. 6 Dec., 1967 [13 Dec., 1966], No. 55869/66. Heading B5A. Hollow fibre-resin articles are made by applying the fibre-resin material to a rigid heatexpansible former, enclosing the whole in a layer of heat-shrinkable plastics material and finally heating the assembly to expand the mandrel and shrink the layer thus applying the desired forming pressure to the fibre-resin material. The heat may additionally be utilized to cure the resin and may be applied via the former which may be of aluminium. The plastics layer may be in the form of a wound tape and its action may be enhanced by vacuum. If desired, a removable porous layer which serves to catch air or gas bubbles forced out of the fibre-resin material may be located directly underneath the plastics layer. Silicone rubber may be used as the resin to give flexible articles.

Abstract: 1336603 Spray carburetters ROBERT BOSCH GmbH 27 Nov 1970 [1 Dec 1969] 56428/70 Heading F1B Fuel injection system for a spark-ignition I.C. engine having continuous fuel injection into the induction pipe comprises an induction pipe section containing a flow measuring element, an induction pipe section containing a butterfly valve and a flexible connection between the two sections of pipe, the measuring element being movable against a restoring force proportionally to the amount of air flowing through the induction pipe to control the opening of a fuel metering valve. Air is drawn through a filter 2, past a plate 4 into an induction pipe section 3 which is connected by a flexible section 5 to a further section 6 of the induction pipe, which contains a butterfly throttle valve 7. The plate 4 is secured to an arm 11 which is pivotally mounted on a pin 12 and has a part 13 which actuates a valve 15. The plate 4 is acted on by the flow of air into the induction pipe and opens valve 15 to deliver a metered quantity of fuel to the lines 24 which lead to respective manifold branches 9. A pump 18 draws fuel from a tank 20 and delivers it to the valve 15. The flexible section 5 of the induction pipe insulates the plate 4 from vibration existing at the induction manifold. The distance between the plate 4 and the throttle valve 7 is at least four times the diameter of the valve 7, so that turbulence created in the air-flow by the presence of plate 4 has disappeared when the air reaches the throttle valve 7.

Title: Indicating instrument
IPC: G01D13/26
Filed: 1969-11-20
Abstract: 1,260,433. Tuning indicators. ERNST & WILHELM BERTRAM. 20 Nov., 1969 [20 Nov., 1968], No. 56918/69. Heading H3Q. [Also in Division G1] An indicating instrument 1 for use in radio apparatus to assist in tuning the apparatus to maximum signal strength at selected frequencies has (i) a pointer 2 which is adapted to move, during tuning, in one direction with increasing signal strength and in the opposite direction with decreasing signal strength and (ii) a pointer 6 which moves with the pointer 2 in the first direction but remains substantially stationary upon at least initial movement of the pointer 2 in the opposite direction so that the pointer 6 can indicate the position of the pointer 2 which represents maximum signal strength. Lost motion mechanism 7 interconnects the two pointers so that when the pointer 2 moves with a decrease of signal strength the pointer 6 follows after an initial movement B, large enough to be readily observed but small enough to embrace signals from, but a single station. The mechanism 7 may take the form of a U- shaped element attached to one of the pointers and embracing the other or of a stop on each pointer for engaging the other, Figs. 10, 11, 12 (not shown), or of a pin-and-slot as shown in Fig. 13. In each case the two pointers overlap when moving with increasing signal strength. A moving-coil instrument is inserted in the circuit of a radio receiver so that when a tuning Knob is turned to bring the receiver into the sphere of influence of a given transmitter the instrument pointer 2 will move over a scale 3 followed by the pointer 6 until a maximum value has been passed, signalled by the pointer 2 moving down scale leaving the pointer 6 indicating the maximum, whereupon the tuning knob is turned back until the pointer 2 returns to the maximum. The pointer 6 is attached to an axle 10 whose pointed ends rotate in bearings in parallel arms of a support, means being provided for adjusting the friction. Part of the axle 10 may be surrounded by a chamber containing silicon grease to provide damping. The pointer 6 and its support are formed as a unit for attachment to the moving-coil instrument and their combination (including a scale) form a unit for attachment to the radio set.  The pointers and coil are fully balanced. The pointers 2, 6; mechanism 7; support structures and housing may be made of plastics material. The support for the pointer 6 may be fastened to the instrument housing by screwing, pegging or adhesive or by snapping resilient parts into engagement.

Abstract: 1,163,607. Lamps. KALLE A.G. 21 Dec., 1966 [22 Dec., 1965], No. 57131/66. Heading F4R. [Also in Division G2] An illuminating device for use in photocopying apparatus comprises a light source 20 which emits light through a wide angle and a grating 17 of reflecting elements which allows some light to pass through unreflected but reflects towards the normal path any rays which deviate from the normal by more than a given angle, which lies between 5 degrees and 40 degrees. The grating is made of polished aluminium or of plastics material having a metallized, preferably aluminium surface, and a thin layer of aluminium oxide impregnated with dye may be provided on the aluminium. Alternatively, if strong reflection in the ultraviolet range is desired the plastics may be coated with tantalum. The reflecting surfaces diverge from one another away from the light source at an angle of 5 degrees to 35 degrees, and are formed on the sides of triangular sectioned portions of the grating, the bases of which face the light source and are preferably also reflective. The bases may be formed in two parts set at an angle of between 135 degrees and 179 degrees. The reflecting surfaces may be flat or curved (Figures 1b, 1c, not shown) and in plan view may form a rectangular pattern, as illustrated, or a honeycomb design of equilateral hexagons. In an alternative embodiment (Figs. 2 and 3, not shown) the grating is composed of quadrant sections (9a, 9b) surrounding a single tubular light source (7) and separated by matt black screens (10a, 10b, 10c), the assembly being mounted inside a rotatable glass cylinder (8) and a fan being provided to blow cooling air over the source. In a modification the grating is replaced by a continuous reflecting element of substantially triangular section which is wound around the tube in the form of a spiral.
