Title: Improvements in or relating to patterning devices for circular knitting machines
Inventor: SCHAEDER JOHANN ALBRECHT
IPC: D04B15/78
Filed: 1964-02-25
Abstract: 1,061,735. Knitting machines. FRANZ MORAT G.m.b.H. April 16, 1964. No. 7871/ 64. Heading D1C. In a circular knitting machine needles 2 are adapted to be selected and moved into a knitting position by means of jacks 1 on a pattern wheel 10 at the or each knitting station rotating in synchronism with the cylinder. The jacks 1 slide in radial channels and are moved outwardly to engage under butts 2' of the needles by compressed air supplied to chambers 12 through a bore 5 in a stationary plate 15 by a tubule 7 controlled by a electromagnet 8 in accordance with the desired pattern. The wheel 10 is rotated by teeth 4 engaging between the needle butts and its axis is inclined to that of the cylinder so that the jacks, after engaging under the needle butts, also lift the selected needles into knitting position as the wheel rotates. The compressed air may only effect a brief initial movement of the lacks, the remaining movement being effected by a stationary cam (19), Figs. 6 and 7 (not shown), on plate (15), a second cam (20) being provided to retract the jacks subsequently. Alternatively the retraction of the jacks could be effected by air pressure under control of electro-magnetic means. Needles not selected may be moved if desired by a further cam into a tuck position so that tuck loops can be incorporated in the pattern. Instead of the axis X-X of the pattern wheel 10 being inclined it may be parallel as at (Z-Z), Fig. 2 (not shown), to the cylinder axis, the jacks (1a) being moved vertically to both select and actuate the needles to knitting position and the wheel being driven through gearing from the cylinder. In another arrangement, Fig. 3 (not shown), the pattern wheel is constituted by the lower part of the needle cylinder itself, the jacks (1b operating in the extended tricks for the needles (2b) and the air chambers behind the jacks being formed by a co-operating annular cam ring. In a machine having a rotary dial (28), Fig. 4 (not shown), carrying rib needles (27) to be selected, the pattern wheel may be arranged above the dial with its axis (Zc-Zc) at right angles to the cylinder axis, the jacks (1c) acting on the butts (27') of the rib needles and the wheel being driven by suitable gearing from the cylinder.

Title: Improvements in or relating to electric glass furnaces
Inventor: CORNELI ANDERS ERIK ALEXANDER
IPC: C03B5/20
Filed: 1944-04-28
Abstract: 577,622. Electrode furnaces. AKTIEBOLAGET SURTE GLASBRUK. April 28, 1944, Nos. 7997 and 7998. Convention dates, April 30, 1943, and March 30, 1944. [Class 39 (iii)] An A.C. electrical glass furnace containing molten glass 6 and floating, unmolten charge 4, and having lateral electrodes 2a, 2b provided on its side walls, has one or more central electrodes 5 supplied with current of a different voltage, as would be obtained by connecting each of the three sets of electrodes to individual phases of a three phase supply. These central electrodes 5, have the effect of neutralising the downward convection currents in the centre of the furnace due to the lateral electrodes 2a, 2b so preventing unmolten charge and air bubbles from being drawn through the out-take 3. The operative surfaces of the central electrodes 5, have an average level which is the same as, or lower than, that of the lateral electrodes 2a, 2b. Modifications include the projection of the central electrodes up through the bottom of the furnace, and the arrangement of the central electrodes in pairs, the latter arrangement lending itself to a four phase current supply.

Title: Carriages for transporting endless-track vehicles on roads and railway tracks
IPC: B60P3/06
Filed: 1933-03-16
Abstract: 401,945. Motor vehicles. KOSSAKOWSKI, T., 15, Mianowskiego, Warsaw. March 16, 1933, No. 8045. [Classes 79 (ii), 79 (iii), and 79 (v).] A carriage or truck adapted for transporting endless-track vehicles on road or rail and to be driven by a motor on the endless track vehicle, is characterised by the feature that the driving wheels of the carriage are connected by cardan shaft or chain gear to the driving mechanism of the endless-track vehicle loaded on the carriage. The carriage may be steered by means of the steering-gear of the endless-track vehicle. In the construction shown in Figs. 1 and 2, an endless-track vehicle or tank 6 is driven under its own power up a ramp 5 of a road vehicle on to side platforms 7. By means of a hand-wheel 9 and screw-and-nut gear 13 a central platform 8, which is connected by levers to the platforms 7, is caused to rise and the platforms 7 to fall so that the weight of the tank is borne entirely by the platform 8. The endless tracks 25 are then removed and the track sprockets 18 are connected by chains 19 and longitudinal cardan shafts 23 to the road wheels 3 which can thus be driven by the engine of the tank. The tank is secured in place on the road vehicle by four screw strainers 16. The steering shaft 26 of the tank is depressed until it is clutched to gearing 28 connected by a shaft 30 to the steering gear 36 of the steering wheels 2. The road vehicle may be braked either by the brakes of the tank or by a hand lever 38 which applies brakes to all four road wheels. In the construction shown in Fig. 7 the tank is driven backwards up the ramp 5 of a rail truck on to endless belts 57 and is secured by a hook 68. The belts 57 are connected by chain gear 64 with one of the rail wheel axles 65, so that when the tracks 25 of the tank are driven in the forward direction the belts 57 are driven and the truck is propelled. Adhesion between the tank and the truck and belts is maintained by means of a handle 70 acting through linkage 74 on clamps 76 which press on bars 78 carried by the tank. Alternatively the hook 68 may be connected to the clamps 76, so that the pull of the tank on the hook may increase the adhesion between the tank and the belts 57. Modifications are described in which (1) the platforms 7 are movable and the platform 8 is fixed, (2) the tank drives the road or rail wheels by means of reversing or other gear connected to the rear end of the gear-box of the tank, and (3) the tank rests on rollers instead of on the belts 57.

Title: Improvements in or relating to hydro-kinetic power transmission apparatus
IPC: F16H61/52
Filed: 1946-03-15
Abstract: 613,948. Hydraulic couplings. BROCKHOUSE ENGINEERING (SOUTHPORT), Ltd., and RHODES, C. G. March 15, 1946, No. 8047. [Class 69 (ii)] - In a hydro-kinetic power transmission apparatus the turbine 13 is provided with valve means adapted automatically to open the ducts 19 between the turbine vanes when either the drag of 'the liquid on the valve . means which is produced by the rotation of the impeller, or the turbine speed itself exceed predetermined values, means being provided for maintaining the said valve means in the open position against the pressure of closure means, for example spring means, so long as the turbine speed exceeds a predetermined value; and irrespective of the drag of the liquid on the valve means. The valve means are constituted by forming each inlet end 18 of the turbine vanes 17 separate from the remainder of the corresponding vane. The ends 18 are carried by a ring 22 which also carries spring-loaded bob-weights 31. The ring 22 moves on a bearing 23 on a supporting ring 24 fixed to the turbine 13 and is provided with lugs 29a, 29b which co-operate with lugs 27a, 27b, on the ring 24 to limit the extent of the angular movement of the vane ends 18. When the impeller 10 is rotating at speeds within its normal operational range, the drag of the liquid which is produced by the impeller and which acts on the movable vane ends 18 causes these to move towards the open position shown in Fig. 2. At high speeds centrifugal force urges the weights 31 outwards, and the weights react against the lugs 27b to move the vane ends 18 into alignment with the main body of the vanes 17, leaving the ducts 19 completely open. As speed decreases, the springs on the weights 31 urge them inwards and the vane ends are moved to the position where the ducts are closed. The vane ends may be displaced manually or may be temporarily locked. According to the Provisional Specification the movable ends may be provided on the impeller, or on the vanes of the reaction member in the case of a torque converter.

Title: Drying artificial silk
IPC: D01D10/04
Filed: 1934-03-14
Abstract: Artificial silk spun on unyielding perforated bobbins is washed and after-treated, e.g. desulphurized, by the pressure or suction method using the perforations, and then, prior to drying, the perforations are rendered ineffective so as to prevent moisture from escaping through them.  By this means irregularities caused by uneven contractions are avoided.  The perforations may be rendered ineffective by closing the bobbins at the ends, or a number of bobbins may be superposed to form a column and the column closed, or the bobbins may be slid on a tube, or the inner surface of the bobbin may be covered by fitting an elastic sleeve. If desired, the drying of the artificial silk may be interrupted prematurely, e.g., when the water content is about 15, 20, or 25 per cent.

Abstract: 472,270. Endless-belt conveyers. BAKER PERKINS, Ltd., and PATERSON, J. C. March 20, 1936, No. 8285. [Class 78 (i)] The alignment of goods in transfer from one conveyer to another arranged in tandem is controlled by means engaging one conveyer and adapted to impart relative lateral displacements to the other conveyer or a part thereof. The panning conveyer 10 transfers dough shapes from a cutting machine 11 to the steel band oven conveyer 12, and is oscillatable about a vertical pivot 20 to ensure the deposition of the shapes in the most satisfactory position for baking. The edges of the belt 12 are engaged by rollers 34 mounted in the end 37 of the framework 13 of the conveyer 10. Cross-bars 18, 23 on the framework rest on balls 17 seated in stretcher bars 14 which are bolted to extensions 15 of the main frame 28 of the machine. The end bearings 25 for the driving drum 24 of the conveyer 10 are carried by arms 26 located between housing members ' 27 fixed to the frame 28 and adjusted by screws 30 which engage the ends of a bar 31 mounted on the frame 28. Ball bearings 29 are placed between the arms 26 and the housings 27. The drum 24 is driven by a sprocket chain 32 which is guided in a vertical direction over guide pulleys 33. In a modification, the drum 24 may be mounted in bearings carried by a U-shaped bracket having a downwardly depending spindle mounted in a bearing and serving as a pivot. When the conveyer 10 is capable of articulation, the frame 13 may be dispensed with. The terminal roller or knife edge of the conveyer 10 may be slidable transversely and may be displaced instead of the frame 13. In another modification, a pair of levers may be provided on each side of the conveyers with their inner ends linked together and their outer ends bearing by rollers on the edges of the belts. In a further modification, a superposed framework carrying parallel guideways which rest lightly upon the conveyer 10 is displaced similarly to the framework. In all constructions the movement of the conveyer 12 may affect detector means which operate a relay or servomotor which, in turn, effects the displacement of the other conveyer.
