Title: Improvements in knitting
IPC: D04B23/00
Filed: 1947-01-27
Abstract: 678,146. Knitting. TE STRAKE, L. Jan. 27, 1947 (Nov. 12, 1946], No. 2488/47. Class 74 (ii). A fabric, e.g; that of Fig. 17, in which oonsecutive loops are made by at least three adjacent needles, in each thread, in lines oblique to the selvedge, first in one transverse direction and then in the other, is produced on a machine having two beds of latch needles, rising and falling in alternation with each other, the needles in one bed being disposed alternately with those of the other bed; and two series of thread guides arranged side-by-side and reciprocating along the line of the needles, so that the threads from the two series cross in the paths of and are taken in pairs by the needles, first of one bed and then of the other, the needles falling to draw loops therefrom and to knock over the loops of the previous course formed in the same way. The fabric is ladder-resistant. The needles 12, 22 are mounted in holders 13, 23, which are reciprocated from the main-shaft 4, through an eccentric 30 and adjustable connecting-rod 32, a rocking lever 36, 37, via an adjustable slot connection 35, and adjustable rods 39, 40. Ground yarns are taken from pairs 5 and 6 of warp beams and fed by thread guiding bars 18, 28, moved longitudinally by stepped cam discs, themselves rotated by the main shaft and operating through rocking levers and adjustable rods. Selvage threads from warping beams are fed by thread guiding frames 49. A number of such frames may be arranged across the whole width of the bed; e.g. for patterning. Weft threads from fixed cones may be laid in by thread guides 62 borne on a carrier 60 reciprocating with a variable stroke. The carrier is reciprocated by a lever 66, rocked about its pivot 67 by the rocking of a member 78 about its pivot 79. The member 78 is rocked by a slide 74 reciprocated vertically by a pin 73 thereon running in a cam groove 72 in a disc 71 driven from the main-shaft. The lever 66 is connected with the member 78 by a pin 80 working in a slot 81 in a disc 82 rotatable to vary the extent of oscillation of the lever. The disc 82 is rotated one way or the other, from the main-shaft, through shaft 68, crank-pin and connecting-rod 97, 98, ratchet device 96, a gear 95 and further gearing, including a tumbler-reverse 90, 89, 88. The position of the tumbler reverse is determined by interchangeable cam segments 94 borne on a disc rotating with the gear 95 and acting in opposition to a spring 93. Fabric draw-off is by means of a pair of rollers 59, one of which is driven, through gearing, from the main-shaft. The stitch length may be adjusted by changing the draw-off tension.

Title: Improvements relating to toasters
IPC: A47J37/08
Filed: 1949-01-31
Abstract: 657,350. Toasters. WILSON GAS METERS, Ltd., G. POOLE, D. C. E., and DOBSON. W. A. Jan. 31, 1949, Nos. 2570 and 20517. Addition to 620,180. [Class 28(i)] [Also in Group XXIX] In toasting bread in holders 10, coupled to a knob 59 which is depressed to lower the bread between gas heated grids 18, the bread then being slowly raised by the sing- ing of a counterweight 24 carrying a leakable cap washer 25 inside a dash pot cylinder 19, the counterweight having a chain 23 over a pulley 22, the rate of air leaking through a needle valve 29 being set by hand turned knob 32 as in the parent Specification. The bread lowering knob 59 carries a cam 56 which on being pushed down with the knob spreads out or moves levers 48, 49 the lower ends 51 of which pivots to open a ball valve to allow full supply of gas from the inlet 37 to the burners 17 through a pipe 39. When the counterweight slowly sinks to raise the bread, the ends 51 allow the ball valves 52 &c. to close gradually thus diminishing (or cutting off) the gas supply to the burners through 39 but allows the gas supply to the pilot jets, if any, to be maintained through the pipe 38. Such controls may also apply to a single bread holder 10 &c. If there are no pilot jets the gas supply is gradually reduced to a minimum. When one bread holder 10 only is to be used the gas supply to the burners at the other side is maintained at the minimum by turning the knob 59 so that the flat portion 57, Fig. 7 of the cam 56 engages one lever 49 and thus fails to move it to open its gas valve. The knob 59 has an indicating mark 61 to show whether one or both sides are being used for toasting.

Title: Lens centering devices
IPC: G01M11/02
Filed: 1944-02-14
Abstract: 582,096. Lens centring devices. BOLSEY, J. Feb. 14, 1944, No. 2679. Convention date, Jan. 5, 1943. [Class 40 (iii)] An arrangement for adjusting the position of a lens or lens blank on a support comprises a photo-olectric cell or cells arranged to be illuminated to effect an adjustment if the lens or lens element is displaced from its correct position. The element 20, Fig. 4, to be centred may be supported on a hollow rotating pillar 21, the interior of which may be continuously evacuated and which has within it a lamp 24 which projects a beam axially of the pillar through element 20. Above the pillar is a plate 34 carrying photo-electric cells 30-33 (see Fig. 2) arranged at decreasing distances from the axis of the pillar and each arranged to control an adjusting dovico such as a member 35, Fig. 4, 54, Fig. 10, or members 55, Fig. 11, for moving the element towards its centred position. If element 20 is not correctly adjusted, then as pillar 21 and the element rotate, light from lamp 24 will fall on at least one of the cells 30-33 and the element will be moved into its centred position. For fine adjustment, the nearest cell to the axis should be displaced as little as possible therefrom. A cell 39 may be mounted axially on the plate 34 and include a lamp 40 in its circuit which is caused to light up when the element 20 is centred. If desired, the lamp 24 may be supported on plate 34 and the element 20 backed by a reflector arranged within the pillar 21. The cells 30-33 and lamp 24 may be arranged to one side of the axis and an inclined reflector used to direct light to and from the element 20. If a concave element is to be centred, a strong convex lens or a concave mirror is employed to produce a converging combination. For centring a symmetrical lens in which light passing through the centre is not deflected, whatever the position of the lens, the arrangement shown in Fig. 8 may be employed. In this case the exciting lamp 48 is mounted off the axis of pillar 21 above the element 50 to be centred and between element 50 and reflector 41 within the pillar is a diaphragm 49 having apertures 51 and 52 equally spaced from the axis which serve to define the beam by which cells 30-33 are excited. If it is not possible to arrange the cells 30-33 at the focal plane of element 20, the arrangement shown in Fig. 12 may be adopted, in which a screen 59 is so disposed in the focal plane that only part of the light from the lens will pass the screen if the lens is not centred and the cells operate when the illumination decreases. If desired, the pillar 21 and element 20 may be arranged with their axes horizontal.

Abstract: 675,743. Detecting impurities in gases. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 5, 1951, No. 2797/51. Addition to 648,367. Class 37. In a vapour detector as claimed in the parent Specification the means for indicating changes in the positive ion current between the electrodes comprises a device for producing an audible or visual signal upon the flow of current through a thyratron, the grid of which is connected to the negative electrode of the discharge device, whereby the valve is rendered conductive when the positive ion current attains a value sufficient to overcome the negative bias of the valve. An electronic discharge device 1 is of the type disclosed in the parent Specification and comprises an envelope 2, a heated positively-charged electrode 3, a negative electrode 4, an air inlet orifice 5 and an outlet orifice 6. The heater 7 for the electrode 3 is energized from the secondary 8 of a transformer 9. A potential difference between the electrodes 3, 4 is established by a secondary winding 11 of the transformer 9. Air is caused to flow through the device 1 by means of a fan 12 driven by a motor 13. The indicating circuit comprises a thyratron 16 having a buzzer 20 in series with the anode 17. The cathode 19 is connected to a tapping 21 on the winding 11. The negative electrode 4 is connected through a limiting resistance 22 to the grid 18 and through a load resistance 23 to one end of the winding 11 through a potentiometer 24. Positively ionized vapour &c. to be detected between the electrodes 3, 4 causes a flow of ion current to the grid 18 of the thyratron 16, which becomes conducting when the ion current is sufficient to overcome the negative bias on the grid. The buzzer 20 then gives an audible signal. A visual signal may be given additionally or alternatively. Specification 652,061 also is referred to.

Title: Improvements in or relating to quick action telemetering systems
IPC: G01R17/08
Filed: 1954-02-01
Abstract: 755,030. Telemetering. COMPAGNIE POUR LA FABRICATION DES COMTEURS ET MATERIEL D'USINES A. GAZ. Feb. 1, 1954 [Feb. 3, 1953], No. 2953/54. Class 40(1) In a telemetering system wherein a torque proportional to the variable to be metered is automatically balanced by the couple produced by a direct current controlled by a regulator sensitive to unbalance of the two torques, two thermionic valves connected in opposition in the D.C. circuit have their anodes energized by a voltage proportional to the magnitude of the variable and their grids excited differentially by another voltage proportional to this magnitude, this excitation being corrected by an auxiliary voltage derived from the moving element of the regulator. Any variation of the variable is thus followed immediately by a coarse adjustment of the balancing D.C. the regulator then giving a fine adjustment with a slight lag. As shown, power in a three phase line A B C, is measured by a wattmeter 6, the torque of which is balanced by that of a galvanometer 3. The wattmeter spindle 8 carries the moving coil 31 of the galvanometer which is fed with the difference direct current of opposed thermionic valves 9, 10. The valve anodes are fed in the same sense over secondaries 23, 25 of a transformer 17 energized from the wattmeter voltage transformer 7. The valve control grids are excited differentially according to the line current over secondaries 35 36 of a transformer 33 series connected with the current transformer 5. The difference plate current of the two valves is filtered at 19, 20 and flows through the galvanometer coil 31 in series with the receiver meter 30. Any change in the line power is followed immediately by a substantially proportional change in the D.C. through the galvanometer. Any deflection of the spindle 8 resulting from unbalance of the two torques thereon, rotates the moving coil 2 of an induction regulator 21 from its neutral position whereby a voltage is induced in the coil 2 by the stationary energized winding 22 and is applied over a transformer 27 differentially to the valve grids to bring the galvanometer back to neutral. A similar arrangement is described, Fig. 2 (not shown), for telemetering a voltage. In this case the primary torque is produced by a voltmeter and both transformers 17, 33 are energized by the voltage in question.
