Filed: 1959-07-01
Abstract: 909,788. Photographic processing methods and apparatus. McCORQUODALE & CO. Ltd. July 1, 1959, No. 22590/59. Class 98 (2). A treatment solution and a gas such as air or nitrogen are intimately and uniformly mixed, for example as when air and the solution are passed through a pump together, delivered to an element to be processed and caused to flow across the element with a scouring action. The aerated solution has very small bubbles which have the functions of (1) carrying away solution containing used chemicals for replacement by fresh and (2) removing medium sized bubbles which may cling to the element and deleteriously affect the treatment and also act as lenses in cases when exposure is required during processing. The treatment may be effected in a tank with a plurality of such aerated solutions in succession and washing water may be circulated thereafter. As exemplified the processing tank embodies the two units 41 of Fig. 10 and is shown also at the lower part of Fig. 1. The latter comprises a storage tank unit 10 with upper tanks 13, 14, 15, 16 and lower tanks 17, 18, 19, 20 which are within temperaturecontrolled water tank 21; a supply tank unit 11 with tanks 23, 24, 25, 26 in temperaturecontrolled water tank 22, which three sets of smaller tanks contain processing solutions. Also in tank 22 is a tank 27 for water or mixed solution, and pipe connections are provided (Figs. 2-6, not shown) whereby selected mixtures from the smaller tanks may be run or pumped to a processing tank unit 12 and thence circulated through the actual processing tanks 41 which are provided with inner transparent walls 44 between which is a lamp housing 42 containing lamps 106 which may be traversed horizontally when reversal re-exposure is effected in the processing. Pipes, pumps, valves, solenoids and motors are described by which processing with the several solutions and washing when required may proceed automatically to completion under control of a timing mechanism 40. Aeration is effected in tank 27 as shown in Fig. 7, wherein water discharged from elbow 90 attains the height 91 of drain pipe 89 and suction thereof at pipe 93 terminating in hypodermic needle 92 allows a controlled quantity of air to enter the needle and proceed with solution to the main 29 of Fig. 10. Also shown in Fig. 7 is a sprinkler 82 by which air in solution in water from pipe 81 is allowed to escape and such water may be used for washing. Specification 681,206 is referred to.

Abstract: 188,113. Brintons, Ltd., and Brinton, C. C. Aug. 26, 1921. Pile-fabric looms.-In looms for weaving tufted or pile fabrics, wherein the yarn forming the tufts is conveyed to and inserted in the fabric by grippers 7 having a rotary movement only, the carriers for the tuft-yarns 6 are moved up and down by jacquard mechanism &c. in the usual way, but are mounted in a fixed yarn carriage 1. The grippers 7 are mounted on a shaft 17 provided with a wheel 16 operated by a rack 14 slotted to receive a lever 12 operated by a cam 10 on a shaft 20, whilst a lever 27 on the shaft 17 is operated by a bell-crank lever 26, a link 34, and a lever 22 from a second cam 21. The grippers are first moved sufficiently in a clockwise direction to withdraw the selected yarns to the required extent and then remain in this position for some time whilst the usual knives are severing the yarns but towards the end of this operation are preferably moved slightly in an anticlockwise direction so as to relieve the tension on the few yarns not severed. The grippers then move in a clockwise direction to insert the pila yarns or tufts in the fell of the fabric. The cam 10 may be made with a central adjustable part 28, which may be substantially concentric with the shaft 20.

Abstract: 950,157. Thermo - conductive devices. ROBERT BOSCH G.m.b.H. June 14, 1962 [June 16, 1961], No. 22839/62. Heading H1K. [Also in Division G4] A supply circuit for flashing vehicle indicator lamps 10, 11 comprises a resistor 12, the resistance of which changes suddenly at a particular temperature Ts. A resistor having a positive temperature coefficient is used in Fig. 1 so that initially current will flow to lamp 10, but when the temperature of the resistor 12 rises to Ts, its resistance will suddenly become very high, and only a low current insufficient to light lamp 10 will flow. Due to the low current, resistor 12 will cool until at temperature Ts it will switch to its low value again and the cycle restarts. A resistor with a negative temperature coefficient may be used. In a further embodiment (Fig. 3, not shown) the resistor may be heated additionally by a heat ing winding connected in the circuit. Resistor construction.-The positive temperature coefficient resistor is of barium titanate, and its transition temperature Ts varied by doping with a rare earth, e.g. cerium lanthanium. The negative temperature coefficient resistor is of silver sulphide and may be doped with sulphur.

Filed: 1931-08-13
Abstract: 369,511. Gauging-apparatus. ZEISS, C., [Firm of], Carl-Zeiss-Strasse, Jena, Germany. Aug. 13, 1931, No. 22847. Convention date, Aug. 18, 1930. [Class 106 (ii).] A method and means for measuring diameters comprises illuminating tangentially the ends of the diameter by light pencils and measuring the distance between interference bands at each end such distance being diminished by the calculated distance of the bands from the surfaces. A table 1 mounted on four legs 2 is provided with a slide 4 displaceable by a spindle 5, the slide carrying two measuring microscopes 9, 10 with axes at rightangles to the direction of movement of the slide. A stepped supporting plate 16 connects the legs 2 on which is provided a glass scale 17 the lower part of the plate 16 being broadened to take supports 20 provided with centres 21 on which the cylinder 19 or other object is mounted. A lower slide 25 moving parallel to the slide 4 carries a collimator 30 provided with a lamp 32 and diaphragm 33 having a fine slit parallel to the line of the centres 21 and passing through the focus of a lens 34. By turning the wheel 28 the light pencil is adjusted tangentially to one side of the cylinder 19. The microscope 9 which has relatively large magnification is now adjusted to image sharply the horizontal plane containing the axis of the centres and so that the illuminated edge of the cylinder 19 lies in the centre of the field. The microscope 10 is adjusted so that a division of the scale 17 is sharply imaged between the double threads of the microscope. In the microscope 9 there is now visible interference bands parallel to the edge of the cylinder. The reticule is adjusted to one band and the values read on the scale 17 and in the eyepiece micrometer 13. This is now repeated for the other edge of the cylinder. The difference between the readings gives the distance between the interference bands which distance to give the required diameter is diminished by the sum of the distances of the bands from the surface of the cylinder obtained by calculation. In another form the microscopes are mounted in the top plate but are interchanged and the scale 17 and supports 20 mounted on a slide the collimator being fixed.

Title: Tunable aerials
Inventor: LAYBOURN IAN
IPC: H01Q9/14
Filed: 1970-05-12
Abstract: 1,263,027. Aerials. PYE Ltd. 12 May, 1970. No. 22935/70. Heading H4A. In an aerial a variable inductance coil is connected between two radiating members. An insulating housing carriers or encloses the coil and one of the radiating members, the other radiating member being secured to it. Means for varying the inductance of the coil in order to tune the aerial comprises a ring which is slidable upon the housing. As described, a portable transmitter-receiver 2, Fig. 1, is connected via a flexible gooseneck section 3 to the lower end of an aerial 1. A tubular housing 6 made, for example, of resin bonded glass fibre, is sealed at its lower end by a ferrule 7, which provides means for attachment to the gooseneck section 3, and is sealed at its upper end by a ferrule 8, which provides means for attachment of a whip section 5 of the aerial 1. Located within and adjacent the upper end of the tube 6 is a coil 9 provided with a ferrite core 10. Said coil is connected to the ferrule 8 and to a radiating conductor 11, which extends to the ferrule 7. A tuning assembly 12 comprises an insulating material tube 13 having secured to its inner surface one or more rings 14 of a non-magnetic conductive material, such as aluminium. Said tuning assembly may be slid between an upper position, when the rings are closely coupled with the coil so that its inductance is reduced, and a lower position, where the coupling is minimal. The coil 9 may be wound upon a former in which is the core 10, in the form of a plurality of short sections placed end to end. Two collars may be cemented inside the tube 6, between which the coil and core assembly is retained together with a compression spring (Fig. 2, not shown). The tuning assembly 12 may be held in position by means of a spring- loaded lever mounted thereon which bears frictionally upon the outside of the tube 6, or a split collet chuck type device may be provided. The coil 9, and also the conductor 11, may be embedded within the wall of the tube 6. The rings 14 may be replaced by a single conductive cylinder of length equal to that of the coil 9, if maximum variation of inductance is required. In another embodiment, the tuning means is ferromagnetic, so that the inductance of the coil is increased (instead of decreased) as the tuning means is moved to encompass the coil. Specification 1,007,896 is mentioned.

Abstract: 1,009,752. Yarn forwarding. ERNEST SCRAGG & SONS Ltd. May 20, 1963 [June 15, 1962], No. 23059/62. Heading D1D. A pair of yarn forwarding means e.g. rollers 1, 4 has associated with it operating means such as a lever 9 a first operation of which allows the rollers to engage to forward the yarn and a second similar operation of which causes the rollers to be moved apart. As shown, the roller pair comprises a lower roller 1 driven about a fixed axis and an upper jockey roller 4 which has a resilient covering 5 and is rotatably mounted on an arm 6 pivoted about a pin 20. Pivoted close to the arm 6, about a pin 8, is a lever 9 which may be rotated through a limited angle by means of a pedal 7 and has a shoulder 24 contactible with the arm 6. The lever 9 is urged to rotate anticlockwise by a spring 16 the strength of which is sufficient to lift the roller 4 against its own weight, and any spring biasing provided, to urge roller 1 and 4 together. At the further end of lever 9 is a rotatable four-lobed cam 11 the tips of the lobes being located at each corner of a rectangle and having associated therewith end stops 18,19 and a striker plate 17. If the apparatus is in the position shown, i.e. with the rollers 1, 4 separated, and pedal 7 is depressed, roller 4 is lowered to engage roller 1 and lever 9 rotates until cam 11 engages stop 18, by which contact the cam is rotated a few degrees clockwise. Upon releasing pedal 7 cam 11 moves downwards until the teeth 14,15 engage the striker plate 17 in which position the shoulder 24 on lever 9 is still separated from arm 6 and the rollers 1 and 4 therefore remain in contact. To move the rollers apart once more pedal 7 is again depressed so that cam 11 moves into contact with stop 18 and is rotated through a few degrees; the pedal is then released and the cam moves downwardly to miss the striker plate 17 and come to rest against the stop 19 so that the rollers are again held apart.
