Title: Improvements in heald shafts and in heald knitting machines for producing same
IPC: D03C9/06
Filed: 1923-04-26
Abstract: 215,187. Hargreaves (Bacup), Ltd., J., and Whittle, F. April 26, 1923. Heald-knitting machines ; healds. -Each heald shaft A, Fig. 1, has the coloured tokening thread a, spaced over a predetermined number of binding or spacing stitches irrespective of the number of pattern healds inserted so that an equal number of warp threads may be drawn between each pair of tokens. For this purpose, when the dobby rocks a shaft D', Fig. 6, to insert a pattern heald, the take-up screw C driving the take-up arm is stopped as usual, but instead of the tokening mechanism continuing to be driven from the continuously-rotated shaft B, it also is stopped. A cam D<2> on the shaft D' turns a lever D<3> so as to operate a clutch B<2> and unclutch from the driven shaft B a pinion b<2> from which the take-up screw is driven. Another cam D<4> turns a lever K to disengage a clutch H from a loosely-mounted worm B and thereby stop the rotation of this worm which is geared to a worm wheel provided with a finger l to engage an arm m. When the worm is rotated, the arm m causes the token finger M carrying the coloured yarn to dip and allow the yarn to be caught in by the knitting mechanism. According to the Provisional Specification a spring-controlled col. lar can engage the worm.

Title: Improvements in magnetic information storage apparatus
IPC: G11C11/06
Filed: 1951-05-15
Abstract: 711,854. Digital data storage devices. REMINGTON RAND, Inc. May 15, 1951 [May 12, 1950], No. 11347/51. Class 106 (1). [Also in Groups XXXV and XXXIX] In a magnetic storage device for binary information, a storage core of high magnetic retentivity is magnetized in accordance with the polarity of a D.C. signal pulse and influences the output of an open-cored second harmonic transductor which functions as a magnetometer. As shown in Fig. 4, the transductor comprises a pair of cores 20, 21 carrying A.C. energized coils 22, 23 which are so arranged as to induce opposed voltages in a common output winding 24. One of the cores is biased by an adjacent storage core 28 which carries a signal winding 32, and a resultant transductor output is obtained having its phase and amplitude determined by the strength and polarity of the magneticallystored signal. Further bias may be provided by a small permanent magnet 35 and by a battery 37 connected in series with the A.C. supply so that the device has zero output for stored signals of one polarity. The device may be mounted in a metal casing 27, Figs. 1 and 3, with the cores moulded in insulating discs 25, 26, the ends of the storage core being arranged in proximity to core 21. Connecting leads from the coils pass through a seal 33 to a multi-pin base 34. The permanent magnet 35 is adjustably mounted on an insulated ring 36 which is set in a recess in the disc 36. Two devices may be connected in cascade, Fig. 8, the rectified output of winding 24 constituting the control signal of the final stage which may have an additional signal winding 55. Each stage has separate bias adjustment provided by batteries 37, 370. In an alternative cascade connection Fig. 9, the output of the first stage is applied to a transformer 53 and then constitutes the A.C. supply for the next stage, independent bias batteries again being provided. The storage core 280 may be a permanent magnet or may carry a winding 54 for coincidental signal effects. The latter feature may be obtained by the provision of two signal windings on a single storage core or by the use of separate cores, Fig. 10 (not shown). When large signal currents are involved the current may be passed directly through the storage core 28, Fig. 11. Instead of connecting the bias battery 37 in series with the A.C. supply, a separate bias coil 60 may be provided.

Filed: 1945-05-04
Abstract: 591,252. Electric resonators. STANDARD TELEPHONES & CABLES, Ltd. May 4, 1945, No. 11348. Convention date, June 26, 1944. [Class 40 (iii)] A coaxial resonator contains a short-circuiting annular piston with clearances between its edges and the inner and outer conductors, so that its position can be freely adjusted ; and resilient annuli which can be expanded so as to look the short-circuiting piston position, while ensuring conductive continuity. These latter may be solid resilient annuli, Figs. 1, 2 (not shown), which can be compressed axially by means of screw threads formed upon four longitudinal guide bars which are geared as to rotate together ; as a result of this compression, metallic strips or coatings are pressed against the conductors so as to ensure conductive continuity. Alternatively the resilient expansible annuli may comprise two rings, Figs. 3, 4, of arcuate segments 28, 29 which are composed of conductive material &c., and can be moved apart so as to grip against the outer and inner conductors respectively. Movement is effected by pumping air, oil, or some other fluid into a tubular resilient annulus 40 Fig. 4, and 41, Figs. 4, 3, through a bore formed in one 44, Fig. 3, of a set of guide rods 18, 44, by means of which the piston can be positioned. Pressure is applied by depressing a piston 49, which is then held down by a catch 53 engaging a collar 54. Electrical continuity is assured by radial bowed conductive strips 39. In a modification, Figs. 5, 6 (not shown), two coaxial annular fluid-pressure chambers are provided with conducting surfaces and, when pressure is applied, lock an annular piston in position, while ensuring a . conductive connection between it and the inner and outer conductors.

Title: Improvements relating to processes and apparatus for conditioning wheat and like grain
IPC: B02B1/00
Filed: 1940-07-10
Abstract: 542,504. Conditioning grain. RILEY, G. W., and SCOTT & SON (LONDON), Ltd., G. July 10, 1940; No. 11510. [Class 58] Wet grain dueficient in internal moisture is put into a vacuum chamber at substantially atmospheric temperature, a vacuum of 12-50 mm. Hg. is applied, the degree of vacuum being insufficient to cause ebullition of the moisture on the grain for any material length of time, and then the vacuum is broken, the surface moisture being forced by the atmospheric pressure into the grain. After the vacuum has been applied, and before it is broken, saturated steam may be passed into the chamber to condense on the cooler grain, but the amount of steam should not be great enough to raise temperature of the grain above 38‹C. (b.p. of water at 50 mm. Hg.=38.3‹C.). The grain may be taken straight from the washer to the vacuum chamber; the washing water may be warm. In Fig. 1 are shown a vacuum chamber 1, vacuum locks 2, 4, vacuum conduit 11 and steam conduit 9. In Fig. 2 a perforated inner wall 21 spaces the grain from the walls of the chamber to allow of ready access of steam and vacuum to the grain. The vacuum outlet may be connected to vertical or horizontal perforated tubes extending through the grain, or inverted V-shaped deflectors may form grain free pockets from which the vacuum draws. Specifications 479,090 and 519,758, [Group XIII]; are referred to.

IPC: B01D3/42
Filed: 1957-04-11
Abstract: 841,774. Electric control systems. ESSO RESEARCH & ENGINEERING CO. Feb. 12, 1958 [April 11, 1957], No. 11924/57. Class 40 (1). In a fractional distillation process the reflux ratio is automatically varied with the gradient of the distillation curve, i.e. the graph connecting boiling-point and rate of take-off. This is done by registering the temperature rise during each collection cycle, and controlling the next cycle accordingly. As shown, a disc W1 connected to a potential divider P1 is moved by a mechanical link with a self-balancing potentiometer which records a still head temperature signal supplied by a thermocouple. At the beginning of each cycle a brake 5 is removed and a disc W2 connected to a second potential divider P2 is driven until a pin R3 on W2 engages a pin R1 on W1. W2 is then braked by S. By the end of the cycle the increase in still temperature will have moved W1 and the difference between the voltages of the two potential dividers represents the increase and is registered on capacitors C1. During the next cycle C2 registers the temperature change and the potential on C1 is applied to a voltage comparison circuit 2 to which a sawtooth waveform from a generator 3 is also applied. The amplitude of the sawtooth increases until it exceeds the voltage on C1. When this happens a solenoid 4 is energized to return the distillate to the tower. The still is switched off automatically if the head temperature begins to drop by a microswitch T in pin R1 which engages pin R3 on braked disc W2.

Title: Labeling machines
IPC: B65C9/18
Filed: 1958-04-15
Abstract: 851,422. Labelling machines. SCHLUTER, H. C. April 15, 1958 [April 29, 1957], No. 11925/58. Class 73. [Also in Group XVII] In a labelling machine advance of an article 65 to its labelling station operates an article sensing device 50 associated with a label sensing device 51 which initiates a cycle of operations in which a label is dispensed from a ribbon to which it is affixed, whilst the next is fed to the station ready for use when another article operates the device. The labels 44 are coated with temperature-sensitive adhesive and initially are lightly adhered end to end on a ribbon 16 of glossy paper on a roll 16a. The ribbon is led from the roll around a guide roller 23, between an electrically heated platen 26 and its covering shoe 49, around a guide roller 28, between a driven roller 15 and clutch rollers 22 and back to a driven drum 29a. A transverse finger 37 co-operating with a spring 52, a projection 42 and a warmed deflector 46 in front of the platen 26 all serve progressively to separate the labels from the ribbon by bending it sharply as it traverses them. The projection 42 is situated in a slot between two upwardly bent fingers 40 and, with them, serves to give the label rigidity by bending it transversely and with the fingers to hold its rear end when it is freed from the ribbon for application. The machine is tilted as indicated in Fig. 5 over a horizontal conveyer path, Fig. la (not shown), which moves the articles 65 perpendicular to the run of the ribbon against a sensing finger 53. The finger 53 rotates a shaft 54 to raise a forked lever 57 carrying a spring catch 58. The catch lifts a pawl 41 by engaging under a lip 72 which at a later stage it overrides. The pawl 41 has a hook 43 which normally engages under the raised lip of the leading label, Fig. 5. Rotation of the pawl disengages the hook 43 from the label and allows a spring 70 to rotate the link 68 on its shaft 67 back onto a stop 64. Cams 75 and 76 on the shaft 67 close two microswitches in rapid succession ; the first switch starts a motor 13 to feed the ribbon forward to detach and present a new label and the second discharges a condenser,' Fig. 8 (not shown), which operates the solenoid 84 of a labelling device. The labelling device comprises a spring returned, air damped connected to a linkage 96-98-97 carrying a roller 92. The roller is pressed down by a coil spring (not shown) at the joint 98 and rests on a stop 100 when not in operation. Meanwhile the pawl 41 is freed by overriding of the catch 58, and falls to engage the already raised lip of the next label on the moving ribbon, by which it is pulled forward to the position shown in Fig. 5. The consequent counter-rotation of the shaft 68 opens the microswitches to halt the tape and recharge the condenser operating the solenoid 84. When the feeler 53 is freed from the article 65 the weight of it and of the lever 57 rotates the shaft 54 back so that the catch 58 re-engages the lip 72 ready for a new cycle.
