Title: Improvements relating to a Double-Twist Twisting Spindle
IPC: D01H7/86
Filed: 1966-10-24
Abstract: 1,158,137. Adjustment of 2:1 twist spindle. BARMAG BARMER MASCHINENFABRIK A.G. 24 Oct., 1966 [26 Nov., 1965], No. 47682/66. Heading D1D. A 2:1 twist spindle comprises a braked let-off flyer and a spring-loaded yarn brake in the spindle, the braking effect on the flyer and the brake being independently adjustable. The flyer is rotated by the yarn as it is pulled off the package and comprises a hub 35 resting on an annular projection 30 of a mounting plate. The mounting plate is reversible and rests on a member 19, being located by pin 33 and a projection 31 from the base of the plate extending into an annular groove 29 in the member 19. Beneath the projection 30 is a recess 28. The braking effect on the flyer is produced by weights placed on the top of the hub which deflect the projection 31 into the groove 29; the effect is varied by changing the weights and by changing the plate for one having a projection 30 of a different degree of flexibility. One yarn brake comprises a cartridge between upper and lower seats 10, 4, the cartridge comprising telescopically sliding members with a spring 6 between them. The lower seating is fixed being provided in a fixed sleeve 1, the upper seating is adjustable being carried by a member 9 threaded onto a member 12. The member 9 is caused to rotate because of fins 15 engaging fins 16 on the inside of the housing; consequently when the member is rotated the member 9 moves upwardly or downwardly to change the position of sealing 10 and the braking effect on the yarn. The member 12 has a flange 19 resting on a ring 2 connected to the fixed' housing. The ring has a spring urged pin 25 engageable with one of a number of blind holes 22 in the member 12 as the latter is turned to change the yarn tension, the degree of tension being indicated by marks 23 on the member which cooperate with a marker 24 on the fixed ring. A ridge 21 on the ring co-operates with the pin 25 to bound the extent to which the member 12 can be rotated. A yarn tube 37 engages the hub screwed on to a tube 20 which extends with clearance through the projection 30, the member 12 and into a recess in the movable seating member 9.

Abstract: 995,987. Making studded tyre covers. STORA KOPPARBERGS BERGSLAGS A.B., and SANDVIKENS JERNVERKS A.B. Dec. 17, 1963 [Dec. 22, 1962], No. 49795/63. Heading B7C. A method of inserting an anti-skid stud into a predrilled hole in a tyre tread comprises the steps of inserting jaw fingers 17 into the hole, spreading apart the fingers to expand the hole, positioning the stud between the fingers in the hole, and retracting the fingers from the hole to leave the stud therein. The fingers, which are urged together by an elastic ring 28a, are radially displaced by axial movement of a plunger 22 whose action may be supplemented by rotation relative to a chuck head 24 of cams 26 integral with a sleeve 25. Retraction of the plunger uncovers a feeder channel 21 in the sleeve 25 communicating with a revolver magazine 30 having axial pockets 35 from which studs are fed one by one by rotating relative to the sleeve the head 24 and thus also the magazine, which is connected thereto by a handle 29 and spring latch and ratchet 37, 38. A stop 36 prevents studs above the bottom one from entering the channel 21. The fingers are detachable by removing the ring 28a. Relative rotation between the plunger and sleeve is prevented by a pin 33 secured to the plunger and slidable in an axial slot 32 in the sleeve.

Abstract: 1,193,927. Measuring lengths of material. METEOR - SIEGEN APPARATEBAU PAUL SCHMECK G.m.b.H. Oct. 29, 1968 [Nov.2, 1967], No. 51165/68. Heading G1M. Material is passed between rollers 20 and through guides 24 to the gap between a counter roller 2 and a measuring roller 1 provided with a rubber band 19. In operation, the angular position of a switch 6 as in Fig.1 relative to the spindle 9 is first set by an operator turning a knob 14 Fig. 2, graduated to show material lengths, to move an endless cord 10 and rotate a pulley 8 connected to the switch carrier 7. The roller 1 is then rotated in a clockwise direction on the spindle 9 by the moving material until a cam 4 on the roller contacts a roller 18 carried by an arm 5 on the preset switch 6 and moves the arm to operate the switch. Actuation of the switch causes the rollers 20 to move apart and cutters 21 to operate and sever the length of material pre-determined by the setting of the knob 14. The rollers 20 and guides 24 may however be dispensed with and the counter roller 20 driven but withdrawn before cutting. When the driving connection between the material and the roller 1 is broken by the cutters a spring 17 returns the roller to its starting position ready for the next measuring operation. In the initial position a pin 15 carried by the roller 1 abuts a finger 16 so that the measuring roller 1 may at its maximum rotate only one revolution on its spindle 9 until the pin contacts the finger again, after which the spring 17 returns the roller to its starting position.

Abstract: 1486294 Distributers YAMATAKEHONEYWELL CO Ltd 27 Nov 1974 [28 Nov 1973] 51327/74 Heading H4P A sequential sample and hold multiplex has a plurality of channels each directing an incoming signal to a respective holding capacitor through a sequentially operated switched isolator, synchronous with a means for sequentially reading the voltage across each capacitor under the control of read signals which lie within the duration of isolator conduction times. Each channel receives an input signal, e.g. IN1 which with pairs of switches SW11, SW21 operated sequentially in pairs pass the signals through a transformer T1 to an amplifier A having a set gain, output from which is led through SW31 closed to a holding capacitor C11. Voltage across the capacitors are read out by transfer switches SW41 &c. which are closed for a shorter period than input switches to remove the effect of back swing of the associated transformer. The switches may be formed by FET devices controlled by a sequence of pulses (not shown). In an alternative arrangement (Fig. 3, not shown) capacitors C11 &c. are connected to the output of each corresponding transformer with the amplifier being repositioned at output of the circuit. In a further arrangement (Fig. 4, not shown) the transformers are replaced by a transfer capacitor (C21)/DPDT switch arrangement working into the input of the amplifier circuit as shown in Fig. 1.

Abstract: 1373767 Photo-electric measurement of area LICENTIA PATENT VERWALTUNGS GmbH and A KLEIN 4 Nov 1971 [4 Nov 1970] 51399/71 Heading GIA [Also in Division G4] A device for digitally measuring the surface area of a piece of material comprises an array of rotat-  able discs which are equi-spaced across the width of a moving conveyer and which are rotated thereby, the material to be measured being conveyed under the discs each of which generates a pulse per unit of rotation, which pulses are fed to a counter only while the respective disc is in contact with the material. In figure 2 discs 21 are fixed on respective rotatable shafts 20 held in pivoted levers 8. Equi-spaced holes 24 in a flange 22 of the disc generate rotation pulses in a photodiode 28, held in an arm 26 of the lever 8. Shafts 20 carry a second disc 23 and each pair of discs  contact the conveyer comprising a number of belts 3, or as shown in figure 2 contact the material 32. A photo-diode 31 carried on a second arm 29 of the lever 8, is positioned between the gap of each pair of discs and senses whether the associated disc pair is running over material or not. In the circuit of figure 3 the photo-diodes 28 set stores 34 which are read out via gates 36 and then reset in turn by a distributer ring 35, and then signals in fact opening gate 36. The gate 38 only passes the pulses from the stores to a counter 40 if the associated photo-diode 31 is shaded from oblong light source 13 (figure 2) by the material, so removing the inhibit input to gate 38. If photodiode 28 becomes blocked with for example fluff from the material, the lack of rotation pulses causes the associated multi-vibrator 41 to cease to operate which provides a fault signal to a monitoring circuit 43.
