Patent GB-174614-A (GB)
IPC: E05B67/22
Abstract: 174,614. Voda, A. Nov. 25, 1919, [Convention date]. Padlocks; lock mechanism, slider-type.-The casing of a padlock is formed of a metal block 1 with parallel holes drilled for the shackle legs, and holes 2 perpendicular to and intersecting one of these to accommodate spring-pressed locking- pins 6 which have constricted parts 6<b>. Corresponding holes 4 are drilled in the link 3a of the shackle 3. A case 7 can slide on the block 1, and when the key 9 is inserted in the groove 8 of this casing and it is pushed towards the block 1, the bits 10 of the key push the pins 6 inwards so that the larger parts of the pins no longer engage the shackle leg, which can then be pulled up for release, the narrow parts 6b of the pins passing through the slots 5 connecting the holes 4 in the shackle leg. Abutments may be provided to prevent the pins from falling out. In the modification shown in Figs. 5 and 6, the shackle leg 3<a> is reduced at its end and has recesses 14 which engage the larger parts of the pins 6 in the locking position. When the hook 11 of the key 9, Fig. 6, is placed in the hole x and swung down so that the bits 10 enter the holes 2, the pins are pushed in to bring their cut-away parts opposite the notches 14 and the shackle can be removed.

Title: An improved system for long distance control of electric motors from one of a plurality of controlling stations
IPC: G05D3/12
Filed: 1921-06-27
Abstract: 186,420. Jackson, W. J. Mellersh-, (Soc. des Etablissments Gaumont). June 27, 1921. Order apparatus. - Relates to systems for synchronous transmission of movement provided with hunting control gear at the receiving station in order to obtain proportional movements of electric or other motors driving order telegraphs. According to the invention, two or more similar control gears enable the driving motor to be controlled by one of a corresponding number of transmitting stations, the other stations being temporarily excluded from control. Fig. 2 shows an arrangement for two-station control. The local power motor 11 is geared to members of two hunting switches 15, 16, the other members of which are in synchronous relation with transmitters at the respective stations. The operator at either station by closing a switch 22 or 23 excites a relay 24 or 25 which completes the requisite control circuits thorugh the corresponding hunting switch 15 or 16, and opens interlocking contacts in the circuit of the other hunting switch, which is thus excluded from control. The power motor then starts and cuts itself out after a proportionate travel. The controlling switches at the two stations may, in addition, be mutually interlocked by mechanical stops actuated by electromagnets. The accuracy of control may be increased by providing additional quickly rotating hunting switches arranged to determine the fine adjustment. Specification 155,586 is referred to..

Apparatus for glueing shoe uppers to insoles comprises a support 2 on which an insole IS and last L having an upper U draped thereon are mounted, and a flexible membrane 16 fixed above the upper so that it can be compressed by fluid pressure, around the upper and thus fold the lap of the upper against the insole, the lap and/or the edge of the insole having been glued. The membrane 16 of perhaps rubber or soft plastics material is fastened in the U-shaped rim of a bell or lid 10 between a clamping ring 14 of semi-circular crosssection and a corresponding groove in the upper wing of the rim. The membrane may have pockets 116 to correspond with the one or more hollow open-top supports 2, Air is evaporated from the supports 2 and from underneath the membrane through nipples 3 and 5 while compressed air enters the bell above the membrane through the nipple 13. The base plate is either corrugated or provided with a wire mesh 1 so that the air can be exhausted from the peripheral part of the plate. In a similar way the membrane may press the periphery of an outsole against the lasted upper and insole. The bell may be hinged to the base and raised or lowered by pneumatic cylinders 124, Fig. 3, pivoted to the base, with bolts 27, connected to pistons of pneumatic cylinders, being able to clamp the bell to the base.

Abstract: 1440431 Die casting machines DIALOY Ltd 17 July 1973 [17 April 1972] 17647/72 Heading B3F A low pressure die casting apparatus comprises a furnace 1 closed at the top by a member 100 provided with a removable plate 4, and upper and lower platens 7 and 6 carrying upper and lower die members 51 and 50 respectively, the lower platen being detachably connectible to both the upper platen and the plate 4 so that the plate can be lifted from the member 100 on upward movement of the upper platen. The member 100 consists of two rings or plates 2 and 3 secured together by studs 20, the plate 4 normally being held within an aperture in the plate 3 by clamping bars 40. During normal operation of the apparatus the lower platen 6 is secured to the plate 3 by studs 30 and wedges (31) and the upper platen and die member 51 are raised and lowered by a ram 15 to open and close the die. To gain access to the interior of the furnace 1 the lower platen 6 is connected to the upper platen 7 by pins 19 and the wedges (31) removed from the studs 30 to free the lower platen from the plate 3. After the lower platen has been raised clear of the plate 3, the feed tube 10, thermocouple 9 and clamping bars 40 are removed. The die and platen assembly is then lowered and lugs 62 depending from the lower platen are secured to lugs 42 on the plate 4. Raising of the die and platen assembly now lifts the plate 4 away from the plate 3 to permit access to the furnace 1.

Title: Improvements in processes for the preparation of alloys with an oxide dispersed phase
IPC: H01H1/0237
Filed: 1964-04-29
Abstract: A sintered alloy body containing an oxide phase, such as a Ag-CdO alloy used for electrical contacts is produced by heating a compact of the mixed metal powders in oxygen to form the required oxide phase followed by recompaction and sintering. Metals which form stable oxides such as Mg, Al, Si, Be, Ca, Ti and Na may be added to the Ag and Cd powders and in addition Co may also be added either as the metal or as the nitrate.  The compressed powder mixture may be partially sintered e.g. at 500  DEG C. in hydrogen prior to the oxidizing treatment at 800  DEG C. in air.  Final sintering e.g. at 700  DEG C. or 800  DEG C. is carried out in air and the sintered compact may then be rolled or extruded.  A Ag-Mg alloy may be used in place of Ag.  Several examples are given and in a modification of the process coated articles may be formed by compressing superposed layers of different powders e.g. Ag-CdO alloy may be formed on a Ag strip.

The movable part 7 of the clutch has a conical rim 8 joined by a web 9 to a boss 10 slidably keyed to the shaft 1. The clutch elements are normally held in engagement by a spring 12 bearing at one end against a ring 13 bearing against the shield 2. A handwheel 14 is secured to the web 9 on the outer face of which are formed two lugs 15 to carry a pivot pin 16 for a lever 17, the lower end 19 of which is adapted to engage a bolt 21 mounted in a bifurcated part 20 on the end of shaft 1. A pointer 14<1> is mounted on the hand wheel. To release the clutch, a finger-piece 18 on lever 17 is pressed inwardly to cause the lever to fulcrum about bolt 21 and move the part 7 away from the face 5. In a modification, Fig. 3, a separate clutch-releasing lever is dispensed with, the actuating lever 22 being pivoted at 24 on the shaft 1 and bearing against a projection 26 on the movable, clutch element 7. The ring 13 abuts the faced end of a boss 2<1> on the end shield 2.
