Title: Improvements relating to machines for forming laps from slivers of fibrous materials
IPC: D01G27/04
Filed: 1934-06-26
Abstract: 423,341. Lap-forming apparatus. WEINBRENNER, J., 14, Rue du CimetiÚre, Thann, Haut-Rhin, France. June 26, 1934, No. 18836. Convention date, June 28, 1933, Addition to 393,171. [Class 120 (i)] The lap-forming machine described in the parent Specification is provided with means operated by the counter mechanism 79, Fig. 1, at the moment when the lap attains its predetermined size suddenly to declutch or stop the feeding and delivery mechanism and simultaneously to engage the lap parting, releasing and expelling mechanism. The length or weight of the lap wound upon the tube 44 is determined by the counter or meter 79 the movement of which is transmitted by a shaft 80 and gearing 81, 82, 83, to a shaft 84 which actuates the clutches 67, 54, Figs. 1 and 2, respectively controlling the feeding and delivery mechanism and the lap parting, releasing and expelling mechanism. The wheel 83 is loose on the shaft 84, Fig. 3, which is driven through a lost motion device comprising a finger 85 projecting from the wheel 83 and contacting with a lever 86 on the shaft 84. A cam disc 87, Fig. 5, engaging a roller 89 on a lever 88 is keyed on one end of the shaft 84 and when the roller 89 passes the ridge a of the cam disc 87 the latter is suddenly rotated under pressure of the roller 89 through about 90‹. The sudden rotation of the shaft 84 is transmitted through gearing 91 to a disc 92 a nose 94 on which engages and rocks a lever 66 to actuate the clutch 67 and disengage the belt pulley 97 from the transmission gearing 98. This stops the machine with the exception of the members 99, 100, 101, 34 which are still driven through the belt pulleys 102, 108. Simultaneously a lever 103 at the other end of the shaft 84 rocks a lever 53 about its fulcrum 104 to engage the clutch 54 and re-establish the connection of the transmission 100, 34, 101 with the toothed wheel 105. A toothed wheel 106 drives the rack bar 34 connected to one of the parts of the clutch 54 as well as the pinion 105. The clutch 54 is driven through the pinions 100, 107 the worm gear 101, the shaft 99 and the belt pulleys 102, 108. The lap winding rollers 14 are rotated by the engagement of the clutch 54 while the ratchet gear 109 prevents the rotation of the remaining parts of the machine so that the feeding rollers 78 are stopped thus causing the lap to be parted between the feed and winding rollers. The clutch 54 also rotates the pinion 106 causing the rack bars 34 to be raised and the completed lap roll released and expelled. Specification 423,342 is referred to.

Filed: 1963-05-15
Abstract: 987,006. Control of D.C. motors. BROOKHIRST IGRANIC Ltd. May 15, 1963 [July 11, 1962], No. 19279/63. Heading H2J. The armature 56 of a D.C. motor is supplied from source 60 controlled by turn-off winding 70 of a magnetic amplifier, the motor field coil 58 being energized from source 92 having a similar control winding 98. Initially, rheostat 144 is set to provide a low speed signal current to control winding 126 so that magnetic amplifier 124 develops a low signal voltage across lines 120, 122. Current passes from terminal 26 through winding 70 and rectifier 32, whilst the circuit through winding 98 is blocked by rectifier 44. As a result, the armature voltage has a reduced value whilst the field voltage is at a maximum. As the signal voltage across lines 120, 122 is increased the armature voltage increases, the field voltage being reduced when the potential at line 120 exceeds that at terminal 28 whereby current passes through rectifier 44 to energize winding 98. A further increase in signal voltage causes diode 32 to block current-flow through winding 70, the armature voltage remaining at its full rated value, and the field voltage being decreased continuously. An armature current-limiting signal is derived from resistor 86, and when this signal exceeds a value set by rheostat 152, winding 128 on magnetic amplifier 124 is energized to oppose the winding 126. The motor may be supplied from a Ward Leonard generator whose field winding is excited by a magnetic amplifier. Alternatively, the magnetic amplifiers may be replaced by electronic amplifiers.

Title: A new or improved method of and apparatus for the manufacture of building blocks and other agglomerates
IPC: B28B1/44
Filed: 1954-07-02
Abstract: 767,611. Moulding concrete &c. blocks. AMET, P. J. M., and TETARD, C. J. J. July 2. 1954, No. 19405/54. Class 87(2). In moulding building blocks from concrete and other aggregates the material, in a moulding box, is consolidated by penetration with a core or cores by means of a sudden impact obtained by dropping the assembly. In an example, Fig. 2, cores 5 on base plate 6 are positioned by locating pins 25 on a floor 22 so as to extend into a moulding box 1 vertically slidable on limbs 27 and held in a raised position relative to the floor by the engagement of a locking stop 33, hinged at 31 on limbs 27, with flange 32. In operation, the cover 2 of the moulding box 1 is removed and the box filled with moulding material. The cover is then clipped in position and the stop 33 released so that the mould box 1 is supported only by the material it contains. The operator then lifts the whole assembly by the handles 26 and drops it thus driving the cores into the moulding material and effecting the consolidation. The cover 2 is removed and the box 1 and core members 5 on base plate 6 are inverted by handles 9, the cores 5 are then removed by gripping plate 6 through handle openings 21 and the box and detachable bottom plate 3 are removed to free the block from the mould. In a modification, Figs. 4 and 5, the assembly is supported by a displaceable table 38 on a slide block 39 mounted for vertical travel along two guide pillars 40. The block 39 is supported by a pedal-operated member 45 pivoted about a pin 44 at the base of pillars 40 and counterpoised by a weight 47 to keep it in the full-line position shown in Fig. 5. In operation, the core members 5 on the base plate 6 are located on the table 38 by pins and the mould box 1 is supported by stops 57 mounted on limbs 60 sliding in flanges 61 on table 38. The box is filled and the cover 2 secured in place, after which the handles 59 are moved horizontally to displace the limbs 60 and stops 57 thus leaving the box 1 supported only by the material to be moulded. The operator now depresses crutch pedal 46 to the dotted line position of Fig. 5 releasing the block 39 so that the whole assembly falls to the base of pillars 40 and the cones penetrate as before. The crutch member 45 may be formed with a series of staggered stepped inclines to enable the block 39 to fall in a number of successive steps.
