Filed: 1966-10-26
Abstract: 1,123,120. Feeding cigarettes to packaging machines. MASCHINEN FABRIK FR. NIEPMANN & CO. 26 Oct., 1966 [28 Oct., 1965; 23 Aug., 1966], No. 48037/66. Headings B8C and B8S. While a fresh delivery container 2 is being inserted above a cigarette hopper 1 in a packaging machine, the level of cigarettes in the hopper is maintained by moving the walls 1a, 1b inwardly. This obviates any appreciable fall by the bottom cigarettes of the new batch. The top of the hopper is closed during this operation by a sliding member 3. The walls of the hopper may pivot about their lower ends, as illustrated, or the upper ends of the walls (Fig. 3, not shown) may pivot inwardly about their upper edges. The walls may be biased inwardly by springs 8 and retracted by rams 9. A light-barrier 5, 6 automatically initiates replacement of the delivery container 2 when the level of cigarettes in the hopper starts to fall.

Abstract: 1443706 Hinges ARTHUR SHAW MFG Ltd 17 Oct 1973 [19 Oct 1972] 48153/72 Heading E2F In a hinge first and second components 1, 2 respectively are relatively pivoted by means of a pin 4 carried by the first component 1 and received in a housing 6 of a second component 2, the first and second components being attached by spigots 5 and 7 respectively to a fixed frame 8 and a hanging casement 11 respectively. The hinge components may be separated by means of opposed substantially parallel flats 4b on the pin 4 adapted to be displaced radially through an elongate slot 12 in the housing 6 when the flats are aligned with the side of the slot after axial displacement of the two components away from one another by a distance equal to the axial length of the portion of the pin without the flat sides when the flats are aligned with the side of the slot 12 in the housing 6. To prevent inadvertent separation of the hinge components when in use, a split ring 10 is mounted on a tapered portion of the pin 4 so that on relative axial movement of the housing limited wedging engagement occurs. This resistance to axial movement during operation of the hinge does not interfere with the normal pivotal operation of the hinge. For Figures see next column

A thread having successive portions with alternate S and Z twist is produced by applying to a substantially untwisted thread two successive double twists by means of an apparatus which is rotated at a substantially constant speed, but the direction or rotation of which is periodically reversed at intervals of time equal to the time taken for the thread to pass between the two double twisting locations so that any portion of the thread is twisted four times in one direction successive portions being twisted in opposite directions. As described the apparatus comprises two rotors 1,2 connected together and rotated about a horizontal axis by an electric, mechanical, or pneumatic motor and optionally idle storage rolls 4 mounted on a stationary frame 5. A thread receives a double twist in passing to rolls 4 via rotors 1 and 2, and a further double twist in leaving the apparatus via rotors 1 and 2. The twist may be set chemically or thermally while the thread is on rolls 4. The thread may be a synthetic thread - for example of polyhexamethylene adipamide filaments - or a natural or mixed thread.

Abstract: 1512980 Clutch control FRIESEKE HOEPFNER GmbH 25 Nov 1975 [29 Nov 1974] 48473/75 Heading F2C A circuit for controlling the rate of reengagement of a motor vehicle friction clutch following gear shift comprises an hydraulic clutch engaging servo 14 controlled by the output from an amplifier 16 responsive to the difference between engine speed and gearbox input speed, the rate of change of the speed difference and to the rate of decay of a stored voltage 17 representative of the speed difference when clutch disengagement commences and which rate of decay is controlled by a discharge circuit 19 responsive to engine speed and the lower of engine speed and gearbox input speed. The outputs from an engine speed responsive generator 1 and a gearbox input speed responsive generator 4 are fed to a difference measuring circuit 3. The output from the circuit 3 is fed through a rectifier 9 to the amplifier 16 and to a differentiator circuit 22 the output 24 of which is also fed to the amplifier 16. The engine speed and gearbox input speed responsive signals are additionally supplied to a minimum value selector circuit 8 which feeds the lower signal to the stored voltage discharge control circuit 19. The engine speed responsive signal is also applied directly through a line 20 to the discharge circuit 19. Increases in the engine speed responsive signal and/or the lower signal increase the rate of decay of the stored voltage and thus clutch re-engagement. When a vehicle clutch pedal is depressed a switching circuit 11 charges the stored voltage circuit and additionally supplies a clutch disengaging signal 13 to the servo motor 14. When the clutch pedal is released the clutch is re-engaged at a rate dependent upon the above defined parameters.

Abstract: 1272656 Super-conducting cables CENTRAL ELECTRICITY GENERATING BOARD 13 Jan 1971 [13 Oct 1969] 50247/69 Headings H1A and A4D A method of making a conductor for a superconducting power transmission cable comprises forming a strip having layers of super-conducting 11, 12 and non-super-conducting 10 materials and then fabricating a tube as in Fig. 2 (not shown) from the strip by butt welding, either longitudinally or helically, opposite longitudinal edges of the strip together, the edges having a continuous coating of a super-conducting material 13, 14 so that no alloying or intermetallic non-superconducting compound formation will occur during the welding and ensuring that the joint remains super-conducting giving a continuous super-conducting surface. The strip can be composed of aluminium or copper 10 with a coating of niobium on its main surfaces 11, 12 and on the edges or with a coating of a hard type II super-conductor on its two main surfaces with a coating of niobium over the type II superconductor. In the latter case, the niobium (22), Fig. 3 (not shown) may extend around the longitudinal edges of the strip or, alternatively, the type II super-conductor extends around the longitudinal edges (26), Fig. 4 (not shown). The type II super-conductor may be a niobium zirconium or a niobium titanium alloy. The edges 13, 14 can be added to the strip by electron beam welding, e.g. a niobium rod or strip, to the edges of the core 10, and then rolling techniques can be used to bond the resulting niobium edged core to the superconducting layers. Alternatively, the components of the strip can be consolidated by explosive welding and in this case the strip so formed is preferably rolled to give a good surface finish and the final dimension. A super-conducting cable is described having coaxial tubes composed of the composite material.

Patent GB-507214-A (GB)
Abstract: 507,214. Supply meters; prepayment mechanism for meters. SANGAMO WESTON, Ltd., and WESTON, G. E. Dec. 9, 1937, No. 34129. [Class 37] [Also in Group XVIII] A charge-assessing device for electricity, gas and other supply meters has means for altering the charging rate after a predetermined consumption, a constantly operating timing mechanism for stressing energy storing means, such as springs, being employed to effect all of the gear changes, so that the metering element is not subjected to loading by the gear change. As applied to a "step-rate" prepayment meter, the energy stored is released to change over from secondary to primary charge whereupon a further energy storing mechanism is stressed to effect a subsequent change from primary to secondary rate. The timing mechanism comprises a synchronous motor 10 constantly advancing a ratchet disc 14, and a disc 16 fixed on the shaft 13. The disc 16 has a. pivoted catch lever 17 the hooked end 20 of which engages a pin 21 on a loose disc 22. The disc 22 is connected to an anchored energy storing spring 24 and is advanced and returned within the limits of slot 27, the return movement being damped by gearing 32. During advance a pin 28 on disc 22 idly passes a lug 29, while on return the pin 28 and lug engage an abutment 81 and rotate the staff 30 in a direction opposite to that shown at f. After the pin 28 passes the arm 29, the staff 30 is rocked in the direction of f due to the stressing of spring 83 which is under control of the meter. The rocking movement of staff 30 operates a two-armed lever 64, the lever 46, and lever 48, the lever 48 operating on the shift lever 50 for the gear change. The operation of lever 64 permits through gearing 58 a pinion 52 to return arm 53 into engagement with stop-pin 54 which is set by pointer 56 for the amount of energy desired at the primary rate. The drive from the meter wheel 34 to pinion 52 is effected through a ratchet-wheel 38 which is engaged by a cranked. lever 39 when the coned head 44 of push-rod 43 seats into an aperture 51 in lever 46. At the end of a primary charge period, the arm 53 engages a pin 70 on lever 68, releases lever 64 and allows the staff 30 to rock in the direction of f. Thie movement changes the indicator 71 and displaces the coned head 44 from the aperture 51. The crank 39 is thereupon disengaged from the wheel 38, and the meter is freed from load due to the gear-changing operations. The secondary-rate period is operative under control of the timing-mechanism which, during rotation of the staff 30 in a direction opposite to f, restores the pointer 71 to the primary' position, re-seats the coned head 44 and permits the arm 53 to abut against the setting stop 64. The periods of primary rate-change are set up on disc 74 and, as described, these occur once a week, the number of teeth on wheel 14 being 84.
