During the night, the generator-absorber and the water in the tank E are cooled and the refrigerant vapour evolved in the evaporator is absorbed in the generator-absorber, while during the day the refrigerant in the generatorabsorber is vaporized and liquefied in the condenser. In another system using an inert gas, the generator-absorber L is disposed in a glass-house K on the south side of a wall, and the condenser M is placed on the north side. The upper and lower ends of the generator-absorber are connected to the corresponding ends of the condenser and the evaporator N through ducts in heat-exchange with one another. During generation, the inert gas circulates between the generator-absorber and the condenser, and during absorption between the generator-absorber and the evaporator. The glass-house may be provided with louvres adapted to be closed during the day. The heating or cooling of the glass-house may be augmented by water circulating through a closed pipe system a part S<2> of which is exposed to the atmosphere. Further, the glass-house may be heated or cooled solely by the closed pipe system. Air may be used as the inert gas, water as refrigerant, and wood or silica gel as absorbent. The apparatus may be used to extract moisture from the air during the night by passing air through a condenser cooled by the evaporator. Specification 436,281 is referred to.

Filed: 1972-04-11
Abstract: 1425701 Boots &c SHOE & ALLIED TRADES RESEARCH ASSOCIATION 11 April 1973 [11 April 1972] 16727/72 Heading A3B Apparatus for preforming shoe uppers includes means for holding the edge of an upper to be formed, a forepart mould 312, a backpart mould 314, and means for moving each mould relative to the holding means from an inoperative position to a moulding position, said moulds 312, 314 when in their moulding positions cooperating to define a substantially continuous moulding surface corresponding to the whole of the upper to be formed. As described the backpart mould 314 has the same shape as the shoe making last and the forepart mould is a development of the last shape i.e. has a flattened last shape. In operation a closed upper, which has previously been rendered stretchable, is placed in the machine with the forepart margin located above a fixed clamping plate 300b, the margin being positioned (as shown in dotted lines in Fig. 3) by pins 308. A movable clamping plate 300a is then lowered by actuator 307 to clamp the edge of the upper U as shown in Fig. 5. The backpart mould 314, which is carried by a lever 392, is then moved from its inoperative position shown in Fig. 5 to its moulding position shown in Fig. 4. During this movement the heel end of the upper is held in position by a backpart gauge 412 (Fig. 5). The forepart mould 312 is then raised from its inoperative position as shown in Fig. 5 to its moulding position shown in Fig. 1 in which it cooperates with the backpart mould 314 to define a moulding surface corresponding to the whole of the shoe upper. The forepart mould 312 is carried by a slide 320 which can be raised by a toggle mechanism operated by an actuator 328 so that the forepart mould 312 enters the upper toe first as shown in Fig. 4. During this latter movement of the forepart mould 312 a pin 350 on an arm 348 engages a cam groove 354 so that the forepart mould 312 is rotated to the position shown in Fig. 1. A female heel mould 580 is then applied to the rear end of the upper and wipers 430, 432 then wipe the heel end of the lasting margin under the backpart mould 314. In a modified clamping arrangement (Fig. 32) the margin of the upper is clamped between a pair of lower clamping plates 702b, 704b and a pair of upper clamping plates (not shown). Each upper clamping plate is pivoted to its corresponding lower clamping plate by hinges 702c, and the clamping plates can also pivot about a vertical axis 714 under the guidance of slots 702d, 704d. In the case of a leather upper having a thermoplastic counter stiffener (which has previously been softened by heating) the forepart mould 312 may be heated by electrical heaters (not shown) embedded in block 316 to set the shape of the forepart, and the backpart mould 314 may be cooled by circulating a coolant therethrough to set the shape of the counter stiffener. In the case of a poromeric shoe upper which has previously been rendered stretchable by heating both moulds 312, 314 may be cooled.

Title: Improvements in or relating to automatic winding machines
IPC: B65H54/22
Filed: 1952-07-03
Abstract: 752,872. Winding thread. REINERS, W. July 3, 1952 [July 3, 1951; July 4, 1951], No. 16769/52. Class 120 (2).  An automatic thread winding machine of the kind having a plurality of independently operating winding units each provided with automatically operating devices for controlling the winding operation including bobbin-changing and knot tying and preferably, also, knot-testing devices, and means for effecting suction from a common source to assist in the operation of one or more of these devices, is provided with a feeler lever 1 on each unit, contacting the thread F being wound, which on the breakage or exhaustion of a thread removes a step 6 to permit a lever 7, 9, 11 to be moved clockwise about a shaft 8 and remove an abutment 10 from a pawl 12, 13 to allow the same to engage a constantly-rotating indexing wheel 17. This movement of the lever 7, 9, 11 is brought about by a nose 28 on a disc 29 fast on a shaft 30 driven through a slipping clutch 34. At the same time the nose 23 of a lever 22, 23 is brought into a notch 31 in the disc 29 to lock the same and all other discs 29<SP>1</SP>, 29<SP>11</SP> against motion. The disc 15, having a cam 16, now moves with the wheel 17 until the cam 16 contacts the lever portion 9 and rocks the lever 7, 9, 11 anticlockwise depressing the rod 19 to remove the nose 23 from the notch 31 in the disc 29 and permit the shaft 30 to rotate again until the disc 29, or those of other winding units, 291, 29<SP>11</SP>, is prevented from rotation by a further thread breakage. The arrangement is stated to avoid too large a demand upon the suction system, since only one winding unit, or a small group, can be attended to at any given time. In the modification of Fig. 2, when the thread F breaks or exhausts, the arms 41, 43 swing counter-clockwise about the pivot 42 to move a step 44 from a spring-urged lever 60, 61 allowing the same to be moved clockwise about the pivot 57 and pull a rod 62 upwardly under the force of a rotating eccentric 54 operating through a lever 56, 59. The movement of the rod 62 operates automatic mechanism as did the rod 19 of the first modification. A pivoted catch 46, operated by a rod 49 from a suctionmeasuring chamber 51 and diaphragm 50, ensures that the mechanism will only operate if a predetermined minimum suction obtained in the system 53.

Abstract: 874,327. Artificial limbs. BLATCHFORD & SONS Ltd., C. A. May 27, 1959 [May 27, 1958], No. 16814/58. Class 81 (2). A locking-device for an artificial knee joint, which is a simplified form of that described in Specification 779,087, comprises a brake band, connected to the thigh, passing around a drum rotatable with the shin, provision for relative movement between the thigh and shin, so as to lock the knee when the leg is bearing weight, and the parts being so positioned relative to each other that the lock is released or prepared for release shortly before the leg is lifted from the ground to make a forward swing in walking. The spindle 5A, which is rigidly connected to the shin portion 2, is mounted for rotation in bearing bushes carried in a pair of radius arms 8, pivoted at 10 to a frame 4 secured to the thigh portion 1. A brake band 11B passes round a drum 6, on the spindle 5A, and around an adjustable block 11C and the pivot 10, to a tensioning adjustment 13C. When weight is put on the leg, the abutment 11C and pivot 10 are lowered, relative to the drum 6, so that the band is tightened and the brake is applied. The angle between the arms 8 and the vertical is between 10 and 45 degrees, so that, towards the end of a stride, when the leg is at the rearmost point of its movement, the arms are nearly vertical and the downward thrust of the wearer's weight has relatively little effect for braking. The brake consequently tends to be released and this is assisted by springs 16 which urge the arms 8 in a counter-clockwise direction.
