Title: Improvements in tensioning devices for ropes, wires and the like
IPC: A63B61/02
Filed: 1952-09-08
Abstract: 706,897. Rope and like strainers. RAU, B. A. Sept. 8, 1952, No. 22559/52. Class 45 In a straining device of the kind comprising a pivoted lever to which one end of a rope, wire or line is attached, the lever being swung through a dead centre position in drawing the rope or like taut so that the pull of the rope or like in its stretched condition holds the lever against inadvertent movement to slacken the ropes or like, the lever comprises a tubular member, the wall of which is slotted lengthwise to permit the rope or the like or a tension element for applying the straining force to the rope or like to enter within the tubular member to a position in which the pull of the rope or like holds the tubular member against inadvertent release. In one construction a tubular lever 20 is pivoted by means of pins 19 to a bracket 14 and a rope passes down the centre of the lever 20 and is attached to a nut 23, the position of which relative to the lever can be varied by a wing bolt 24 bearing on the end of the lever to adjust the degree of tension applied to the rope The lever has a slot 21 extending from the pivoted end for part of its length so that when the lever is raised the rope can pass through the slot to release the tension. The rope passes over a pulley 16 and through an aperture in the first and the position of the pulley 16 and pins 19 is such that when the lever is in its downmost position, a toggle is formed so that the lever is retained in the tension applying position. A pin may be passed through the pivot pins 19, which are hollow, as an additional safeguard. In a second construction tension is applied to the rope by a weight. This weight is attached to a rod 34 which is pivoted to one end of a slotted tube 31 which is attached by a pivot 32 adjacent the rod pivot to a stirrup 30 which is carried by the rope. In the position shown in Fig. 6 the weight (not shown) rests on the ground but when the tube is swung about the pivot 32 the rod 34 assumes a position inside the tube and so raises the weight from the ground to apply tension to the rope.

Abstract: 1,171,089. Boots &c. J. S. KAMBORIAN. 13 May, 1968 [23 June, 1967], No. 22616/68. Heading A3B. A pulling over assembly in a lasting machine includes a support for supporting a last bottom down in the machine, two side grippers which can move lengthwise of the shoe, brake means for locking the lengthwise position of the grippers and manually operable control means for operating the brake means. As described the lasting machine is of the type described in specification No. 1,108,221 having a modified side gripper arrangement and a modified heel clamp. The side grippers 138 (Figs. 12, 13) are carried on an air motor 124 which is mounted on a base plate 108 by a universal coupling (not shown). A bracket 212 is mounted on the base plate 108 and carries a shaft 236 having an arm 240 pinned to one end and an arm 244 pinned to the other end. The arm 244 is connected to the motor 124 by a link 268 and the arm 240 carries a handle 248, thus lengthwise movement of the handle 248 causes lengthwise movement of the motor 124 carrying the side grippers 138. A brake lever 228 can be moved by an air motor 222 so that teeth 229 on the brake lever 228 engage teeth 246 on the arm 240 thus locking the arm 240, motor 124 and side grippers 138 against lengthwise movement. Operation of a push button (not shown) in one of the handles 248 releases the brake 228 and releases tension in the side grippers 138 and operation of a push button (not shown) in the other handle 248 releases the tension in the toe gripper (not shown) thus allowing the position of the upper on the last to be adjusted by manipulation of the handles 248. The heel clamp 391 (Figs. 22, 23) is pivoted by pins 388 to a holder 380 which is adjustably mounted on an upright 374. When the heel clamp 391 is moved towards the shoe the clamp 391 tilts to accommodate itself to the shape of the shoe. The clamp 391 can be locked in this position by a pair of plungers 392, 392 which are moved outwardly by air pressure until teeth on the plunger engage teeth on wings 408 fixed to the clamp 391. The heel clamp 391 is locked in position when the position of the shoe upper on the last is being adjusted to prevent movement of the last.

Title: Improvements in the production of gases rich in olefines from bituminous coals
IPC: C10B51/00
Filed: 1927-09-01
Abstract: 301,775. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 1, 1927. Coking processes.-A gas rich in olefines is produced from bituminous coals, such as brown coal, by heatingthe pulverized or granulated coal rapidly to about 800‹ C. and then rapidly cooling the gas and coke. This may be done by passing the coal quickly through the reaction chamber with the assistance of gases such as superheated steam and cooling the products in an adjacent chamber. By passing a solid inert substance such as sand or metal fragments through the reaction chamber either with the coal, or separately therefrom the deposition of coal and coke may be prevented. Wet coal should be dried before use so as to avoid the water gas reaction. The tar obtained may be returned to the process either by injection into the reaction vessel or by impregnating pumice with the tar and feeding the pumice with the coal. Suitable apparatus comprises a vertical pipe 5 metres long and 50 m.m. in diameter constructed of nickel-chromiumiron alloy and heated externally by hot gases, or electrically to about 800‹ C., the powdered charge falling through this tube. The gases obtained include 19 per cent Cn H2n and homologues of ethylene which may be absorbed in active charcoal which, on subsequent treatment with steam, gives a colourless liquid containing amylene, benzine and the like and boils between 30‹ and 100‹ C. Hot sand introduced through a hopper A is further heated in a tube B by a furnace C and together with powdered brown coal from a hopper E is dropped through a heated tube D.
