Title: Injection process and sole
IPC: B29D35/06
Filed: 1962-07-03
Abstract: 944,545. Injection moulding shoes. JOSEPH F. CORCORAN SHOE CO. Inc. July 3, 1962 [April 12, 1962], No. 25380/62. Heading A3B. [Also in Division B5] A process of manufacturing shoes comprises enclosing a lasted shoe bottom and a preformed tread forming piece in spaced relationship within a mould, injecting a plastics material in a fluid state into the cavity between the tread forming piece and the shoe bottom, causing the injected plastics material to fill the cavity and flow around the edge of the tread forming piece and subsequently curing the plastics material thereby to bond the tread forming piece to the lasted shoe bottom. In the embodiment described the mould comprises a sole mould component 10, and co-operating side moulds 11 to which are secured inwardly bevelled welt plates 12. A sole piece 20 is held in fixed position on the bottom of the sole mould by plungers 13 carrying sharp spurs and a leather heel piece 21 is placed in the heel cavity of the mould. The sole mould is provided with an inlet passage 14 located approximately midway between the toe and heel ends of the mould, and an outlet passage 15 at the heel. The mould cavity is closed by the lasted shoe bottom on the last 16 and includes a conventional insole 17 and a heel lift 18. A fluid plastic compound such as polyvinyl chloride is injected under pressure through the inlet 14 until the mould cavity is solidly filled, and a continuous layer 22 has been formed between the sole piece 20 and the insole 17 and a thicker marginal band 24 around the side edges of the sole piece. Rivets may be inserted near the rear edges of the sole piece 20 to reinforce the bond. A sole piece having a shank extension projecting rearward to or beyond the heel breast line where it is securely anchored beneath or adjacent the moulded heel may be used.

Abstract: 627,307. Electric winches. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 26, 1946, No. 25483. Convention date, Oct. 7, 1944. [Class 78 (v)] A winch drum 4 and capstan 2, 3 is provided with a motor comprising two members which rotate simultaneously in opposite directions at different speeds ; the one (e.g. armature 5) at a slower speed winding the cable 1 from the capstan 2, 3 on to the drum, and the other (e.g. rotor 6) at higher speed driving the capstan, through reducing gear, the capstan 2, 3 feeding the cable to the wind drum 4. In the Fig., the armature 5 drives winch drum 4 through pulley 14, belt 16, pulley 15, shaft 17. Coupling 18 limits the torque transmitted to the drum and therefore the pull transmitted. Rotor 6 drives capstan drums 2, 3 through pulley 7, belt 9, pulley 8, shaft 10, pinions 11 and pinions 12 or 13. The armature 5 may be used as the winch drum. The motor may be formed with stationary armature and two rotors, the latter serving to drive the drum and capstan respectively.

Title: Homogeneous nuclear reactor
IPC: C01B3/04
Filed: 1957-08-14
Abstract: 843,650. Nuclear reactors. NORTH AMERICAN AVIATION Inc. Aug. 14, 1957 [Aug. 20, 1956], No. 25650/57. Class 39(4). A homogeneous reactor with an aqueous core is operated below atmospheric pressure so that the radiolytically produced hydrogen and oxygen may be recombined with less risk of explosion. These gases, with water vapour, are led from the core of enriched uranyl sulphate through a reflector of graphite or beryllium by a pipe 4 to the cylindrical housing 6 of a recombiner 3. Within this housing pellets 10 of platinized alumina are held between a mesh 9 and a hollow inner cylinder 7. Cooling coils 12 condense the recombined water vapour, which returns to the core through a drain hole 18 and the pipe 4. Core solution overflow due to transients is deflected at 16 to keep the catalyst dry. The preferred pressure of operation is 200 mm. of mercury and temperature 20-30‹C. A tube 19 connects to a pressure transducer, temperature is measured by a thermocouple at 21. A line 20 leads to a vacuum pump and a heater 23 may be used. Parts of the recombiner are of "Nichrome" (Registered Trade Mark). A modification for very low power reactors is also described. Specification 817,067 is referred to.

Abstract: 973,161. Ski bindings. H. MARKER. July 19, 1961 [July 21, 1960], No. 26203/61. Heading A6D. An adjustable detent device for constraining movement between a rotatable boot engaging part and a part fixed to or integral with the ski comprises a detent member urged to engage in a recess in one part by a helical spring, the force exerted by the spring being adjustable from a minimum to a maximum value by swivelling or turning a setting device through an angle of less than 360 degrees, the setting device being provided with latching means by which it is selectively latchable in any one of a plurality of angular positions. An eccentric cam 10 pivoting on a fixed plate 14 on the ski presses a ball 6 into a socket 9 in a cheek-plate 3, pivoting on a base plate 1 on the ski and engaging the front edge of the sole of a ski boot. The cam acts upon a member 12 which presses on the ball 7 through a spring 8 in a longitudinal hole in a fixed part 5. The pressure on the ball is varied by adjusting the position of a lever 13 connected to or integral with the cam. A pointed screw on the lever engages in a selected one of a series of recesses 17 in the fixed plate 14. Various other means for varying the pressure on the ball to vary the pressure that can be exerted on the plate 3 before it becomes free to pivot are described. A cam with peripheral depressions which selectively engage a projection on the pressure member is rotatable by a knurled disc. A rotatable rod acting directly on the spring 8 has a projection extending into one of a number of recesses in the side of an inclined slot in the bearing block for the rod or the rod may be eccentrically pivoted on a rotatable lever. The detent device may be arranged on a pivoting member.
