Patent GB-223619-A (GB)
Title: Improvements in and relating to knitting machines
IPC: D04B15/66
Filed: 1923-04-25
Abstract: 223,619. White, A. E., (Jacquard Knitting Machine Co., Inc.). April 25, 1923. Circular machines. - To enable a great variety of patterns or designs to be formed in knitted fabrics a jacquard pattern mechanism is used to control the operation of the needles. The needles 11 of the circular machine shown in Fig. 1 are operated to form knit tuck, or welt stitches by the action of cams acting on butts on the needles and on needle-lifting jacks 22. The stitches are cast only after the needles have been raised to their highest position by the jacks 22, and this only takes place when the jacks are raised by levers 27 to raise their butts into the path of the jack operating-cam. The levers 27 are operated only when spring-withdrawn selectorbars 35 of the jacquard mechanism are interposed between those levers and camoperated plungers 33. The selector-bars are operated against the action of their springs by grooved rollers 40 acting on their fingers 38 when these pass through perforations in the pattern sheets 12 which are caused to move forward step-by-step. A series of jacquard mechanisms may be arranged all round the machine or a series of selector bars may be coupled up to and operated simultaneously by a single jacquard mechanism. In a modification the jack raising- levers are brought into operative position and raised by cams, the release of catches which retain them in such position against the action of springs being controlled by cords connected to the jacquard mechanism. This modification is shown provided also with two sets of dial needles with separate operating-cams and four yarn carriers. To enable one positioning of the jackraising levers to be used for each set of colours, those levers are shaped so as always to engagethe jack butts and are slotted on their undersides to allow the passage of the cams which correspond to the colour of yarn which it is desired to pass without knitting. The catches forholding the jack-raising levers in their forward position may be released electrically, the circuits being controlled by spring contacts resting on pattern sheets of insulating material passing over metallic drums.

Title: Improvements in and relating to electric motor controllers
IPC: H02P23/00
Filed: 1930-04-09
Abstract: 349,231. Master control of motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutler- Hammer Manufacturing Co.; Milwaukee, Wisconsin, U.S.A.) April 9, 1930, No. 11286. [Class 38 (iii).] Travelling between predetermined limits; continuous reversals.-A motor 4 for driving a skip hoist or like apparatus between limits is controlled so that it is brought to rest at each limit, and reversed after a time interval by means of a single relay. With loading at the lower limit completed, a pushbutton 8 is depressed energizing the coil 6a of a switch 6 which maintains itself closed over contacts 6b. Thus coils 5a, 12a are energized, the former closing a switch 5 and starting the motor, and the latter holding the contact arm 12b of a switch 12 above its contacts 12c. On reaching the upper limit, switches 9a, 9b are opened, and a switch 13 closed, by a member 17 travelling on a screw 18, so that the coil 6a is de-energized and the switch 6 opens to de-energize coils 5a, 12a, and so open the main switch 5, and stop the motor. The de-energization of the coil 12a allows the contact arm 12b to fall and after a time interval, determined by a dashpot 12d to bridge the contacts 12c, and switches 11a, 11b having closed at the beginning of the upward movement, the coil 7a of a switch 7 is energized. The switch 7 closes and maintains itself closed energizing coils 12a, 5a so that switch 5 closes again, and the motor is reversed, the switch arm 12b being again held above its contacts 12c. By similar operations the motor is stopped at the lower limit and reversed after a time interval. The switch 15 is a stop press button switch and the switch 16 is opened to prevent the automatic reversal of the motor when the bucket is required to stop in its loading position. A pushbutton 10 serves to start the motor in its bucket lowering direction. Under no-voltage conditions in the motor circuit the control circuits are rendered ineffective.

Filed: 1975-03-20
Abstract: 1488443 Finned heat exchanger tubes SHARP KK 20 March 1975 [20 March 1974 30 April 1974 4 Feb 1975] 11718/75 Heading F4S [Also in Division B3] A method of making a fin for a finned tube comprises forming a continuous series of transverse corrugations in a strip of material, flattening the corrugations along a longitudinally extending portion of the strip, and bending the portion and the remainder of the strip relative to one another longitudinally of the strip. The strip A may be flattened in a central region B, and bent to form a U-shaped strip B or flattened at one edge to form an L-shaped strip. The formed strip is then wound helically around a hollow tube 11. The strip A is fed from a reel 1 through guide rollers 2, 2<SP>1</SP>, corrugating rollers 3, 3<SP>1</SP> and flattening and bending rollers 4-7<SP>1</SP> to form a corrugated strip B of U-shaped section. The rollers are all adjustable by vertically movable adjusting screws, e.g. (2A), (2<SP>1</SP>A), (7A), (7<SP>1</SP>A), Fig. 11 (not shown). A plate spring 12 and adjusting screw 13 are provided for reducing the wavelength of the corrugations before the flattening operation. The strip B is wound around the tube 11 using a pressure roller 8 and guide rollers 9, 10. The tube 11 is rotated and moved longitudinally during the winding operation by feeding rollers 39, Fig. 13. A motor (19), Fig. 10 (not shown), drives a toothed gear (17) which in turn drives a gear 18 and a rotor R. A gear 26 attached to the rotor drives a bevel gear 31 through gears 27, 28, 30. The bevel gear 31 meshes with a further bevel gear 32 and through gears 34, 36 drives friction rollers 39 to feed the tube through the housing 5. The finned tube may be bent into a serpentine shape to form a heat exchanger, Fig. 14. The corrugated fins B 2 , Fig. 15, can be flattened and provided with holes to increase the heat transfer coefficient and reduce the ventilating resistance. The coefficient may also be increased by causing the base B 1  of the strip B to bite into and deform the surface 11a of the tube 11 during the winding operation.
