Title: Improvements in or relating to circular knitting machines
IPC: D04B15/60
Filed: 1964-09-11
Abstract: 1,083,636. Knitting-machines. R. PARTHUM. Sept. 11, 1964 [Sept. 26, 1963], No. 37305/64. Heading D1C. A circular machine has yarn severing and removing means comprising a suction duct, and two co-operating severing members rotating in different planes, mounted below the welt dial. A disc 29 carrying a cutting ring 31 is mounted below the dial 3. The disc is engaged by a pin 27 at one end of a shaft 26 eccentrically mounted in a tube 24. The shaft and tube may be adjusted by means of a gear 39 and hub 37 respectively, to displace the ring eccentrically of the dial so that it abuts the second cutting member 42. While the dial rotates the shaft and tube are held stationary so that successive parts of the ring 31 engage the second cutter as it rotates. The threads may be cut further from the fabric by positioning the disc concentric with the dial and severing the threads between a ring 59 and a cylindrical cutting member (58, Fig. 3, not shown).

Abstract: 1313369 Automatic speed control BERGENS MEKANISKE VERKSTEDER A S 3 Aug 1970 [20 Dec 1969] 37419/70 Heading G3R A brake for a windlass which operates a ship's anchor has a drum carrying a number of magnets associated with a speed-detector which transmits pulses to a frequency-responsive relay. A hydraulic motor for operating the brake is controlled by an electro-magnetic valve which responds to the relay so that the speed of a released anchor is stabilized by applying or releasing the brake. An accumulator stores energy for operating the brake motor on failure of the normal supply. The pulses from the speed-detector are also transmitted to a unit for indicating the outboard length of the anchor-chain. The frequencyresponsive relay controls a further relay adapted to energize an alarm. The brake motor may be remotely controlled from the bridge.

Title: Means for indicating or utilising changes in tension of webs and the like
IPC: G05G15/08
Filed: 1958-11-22
Abstract: 875,508. Tension indicators. MARSH, J. C. Nov. 19, 1959 [Nov. 22, 1958; July 9, 1959], Nos. 37667/58 and 23560/59. Class 106 (2). [Also in Groups XVI, XXIV and XXX] In a device for indicating and/or utilizing changes in tension of a driving or conveyer belt 1, rope or chain, or of a moving or stationary web, such as textile or newsprint, or a thread in a sewing machine, wherein a jockey pulley 6 is transversely loaded on to the tensioned belt 1 and its transverse movement measures belt tension, the transverse load, spring 12 or gravity, is applied to the jockey 6 through a linkage, such as a toggle 4, 5, and bell-crank 10, which affords the load a continuously decreasing mechanical advantage as the jockey moves outwards towards the straightening position of the belt, thereby permitting increased movement of the jockey in the fully deflected high-tension region, where such movement would otherwise be too small to utilize. The response may thereby be made approximately linear with tension. In Fig. 1, the bell-crank 10 actuates, through an adjuster 18, a microswitch which disconnects the belt drive on overload; or the lever 10 may actuate a variable-speed gear to reduce the overload or maintain the belt load constant; or adjust the circuit of a driving electric motor. In long conveyer belts several such devices are installed at intervals along the belt to detect and correct unequal tension distribution. In a simple indicator, Fig. 2 (not shown), the toggle link 5 directly actuates a spring-loaded lever moving over a tension scale. In Fig. 3 (not shown), the toggle levers are replaced by an equivalent bowed leaf-spring, longitudinally spring-loaded. In Fig. 4 (not shown), the jockey is guided transversely and is connected to a single spring-loaded link slidable at its opposite ends in slots at right-angles in a guide plate.

Abstract: 1,197,991. Electric digital calculators. STANDARD TELEPHONES & CABLES Ltd. 17 Aug., 1967, No. 37851/67. Heading G4A. A data processor comprises a plurality of active storage registers, the quantity stored in a register being represented by the difference between the count in that register and the count in a reference register. Each register A, B, C comprises a synchronous binary counter stepped by clock pulses only if the associated input gate is on. Each gate is controlled through an OR gate (Fig. 2, not<SP>4</SP>shown) by four AND gates, each of which is controlled by the presence or absence of data and by a programme sequencer. Register A provides the phase reference for B and C. Data may be read into B and C without change of A and after processing, such as multiplication, division, taking the square root, or transformation of rectangular, polar or hyperbolic co-ordinates, the answer may be read out of B or C by stepping along with A. With suitable programming the system may be used for digital differential analysis, or combined with analogue inputs or outputs, and may provide trigonometrical functions. A bi-stable stage in the output of a counter (Fig. 2, not shown) indicates the sign of the output.

[Also in Group XII] Mineral and solid fuel are automatically distributed over a kiln from bins 2, 3, Fig. 1, by a turn-table 8 secured to an endless conveyer 9 whose discharge end 11 is moved both concentrically about the centre of the kiln and also in a radial direction. The conveyer 9 and hoppers 12, 12a which feed the material and fuel respectively on to the conveyer are rotated about the central axis of the kiln by the turntable 8 on which they are mounted. The conveyer is also moved radially with respect to the kiln. The radial movement may be continuous so that the path followed by the discharge end is a spiral or the radial movement may be intermittent so that the discharge end moves along concentric circles of increasing or decreasing radius. The material passes through a screening channel 13 which co-operates with a second endless conveyer 14 to lead the screenings to an aperture 15 at the side of the kiln. In a modification, Figs. 3, 4 (not shown), the radially displaceable conveyer is replaced by a conveyer which is rotatable about a pivot point offset from the vertical axis of the kiln, the charging material being delivered at the pivot point of the conveyer and distributed at the discharge end, which end is adapted to execute arcuate movements between the wall and centre of the kiln. In a further modification a pivotable conveyer, the charging apparatus, storage bins and protective cover are rotatable by the turn-table.

Abstract: 1,216,072. Gyroscopic apparatus. E. FISCHEL. Sept. 9, 1965 [Sept. 23, 1964], No.38605/65. Heading G1C. A gimbal mounted gyro stabilized platform is characterized in that the platform and the gimbals are mounted in a closed platform casing filled with a liquid, the specific weight of which is equal to the resulting specific weight of the platform and the individual gimbals. By this means, gimbals, platform and liquid are moved as an integral and, when mounted in an aircraft or rocket, no deforming forces due to accelerations become effective on the gimbals, which forces could give rise to resonance oscillations of the gimbals. Thus only the ordinary aircraft or rocket vibrations without resonance amplification become effective on the gyros.

[Also in Division A4] A stool comprises a platform base 13, a seat 10, extendible and retractable post structure 11, 12 rising from the base centrally thereof and supporting the seat 10, power means for extending the post to raise the seat, means such as a valve 34 controlling operation of the power means, and means for actuating the control means, the actuating means having a foot-operated portion 44 at least partially surrounding the post structure 11, 12 above the surface of the base 13. The post structure consists of a post 11 and tube 12 which together form an hydraulic assembly. A sleeve 15 is secured to the upper end of the tube 12. As shown in Fig. 4, the footoperated part of the actuating means consists of a ring 44 encircling the post structure. The actuating means also consists of a lever comprising a pair of rods 45 depending slidably through the base 13 from the ring 44, a bearing ring 47 slidable along the lower end of the post structure (Fig. 5) and a working arm 48 projecting from the ring 47. The arm 48 is secured to another lever arm 49 provided as part of valve 34 and pivoted at 50 to operate a spring-loaded plunger 35. The valve 34 is opened by pressure on the ring 44. This permits entrapped compressed air in a reservoir 32 to expand and force hydraulic fluid from this reservoir 32 into tube 12 to raise the seat 10 when the user takes his weight off the seat. A non-return valve 37 prevents fluid flow in the cylinder-reservoir direction. A bleeder passage 51 provides for gradual return of fluid to the reservoir 32 and thus a gradual lowering of the seat under the weight of the user when pressure is applied to the foot ring 44. The post is made in two parts 11, 11-1 so that the seat 10 can be raised independently of the power system. An abdominal rest 17 is provided which may be adjusted vertically, horizontally and rotatably relatively to the seat 10 by means of members 23, 21 and 29 respectively.
