Title: Improvements in or relating to vices
Inventor: O'HANLON BERNARD MARTIN
IPC: B25B1/08
Filed: 1950-06-09
Abstract: 697,611. Vices. GARTHWAITE & SON, Ltd., E. F. Aug. 29, 1951 [June 9, 1950], No. 14451/50. Class 61 (ii). In a vice, a cam 15 mounted on the base to turn about a fixed axis imparts clamping movement to the movable jaw 5 through a thrust transmitting rod 12, 13 which has screw threaded engagement with the movable jaw to provide initial adjustment. The jaw 5 is carried by a block 6 slidable on a raised platform 2 on the bed 1 and is connected by webs to a plate 7 mounted to travel against the underside of the platform. A tension spring 9 connects the plate 7 to the distant end of the bed. The thrust rod has a threaded portion 12 screwed into the block 6 and is provided with a manipulating nut 14. The other end of the thrust rod is slidable and rotatable in a cam housing 10 secured to the platform 2. An eccentric-shaped cam 15, mounted on a vertical pin 16 on which is mounted the hub part 19 of a handle, is provided with an upstanding pin 18 engaging a hole in the hub. Partial rotation of the handle causes the cam to impart suitable travel to the jaw 5.

Title: Improvements in or relating to overload release clutches for mechanical drives
IPC: F16D43/20
Filed: 1945-06-08
Abstract: 592,916. Overload release clutches. GLOVER, WEBB, & LIVERSIDGE, Ltd., and EVANS, L. W. June 8, 1945, No. 14555. [Class 80(ii)] A clutch permanently disengaged on overload comprises an operating member connected to a driving member through a series of springs whose ends are mounted on each member and which shorten by flexion on overload to disengage a dog clutch member rotating with but having limited axial freedom relative to the operating member, so that the latter can return to its no-load position on the cessation of overload leaving the clutch disengaged. As shown, an operating disc 6, Fig. 1, connected to a driving disc 3 on the tubular driving shaft 1 by built-up or unitary blade springs 21, is slidably splined on a driving clutch member 8 itself free to rotate and slide on the shaft 1. The member 8 has axial dogs co-acting with similar dogs 13 on a driven clutch member 14 also journalled on the shaft 1 and carrying a driven sprocket 16. The springs 21 pass through radial slots in the discs 3, 6 and are secured thereto by spring rings 37, Fig. 4, clipped to the discs. Flexing of the springs 21 under excessive torque causes the disc 6 to move the member 8 to the left through an abutment ring 10 mounted thereon, the dogs being disengaged and remaining so until manually re-engaged through a plunger 22 sliding in the shaft 1 and carrying a rod 27 co-acting with the rear of the member 8. Alternatively, a selector fork on the member 8 may provide manual engagement and disengagement. There is a rotatable casing 31.

Abstract: 850,570. Electric heating resistances. GENERAL ELECTRIC CO. May 1, 1959 [May 7, 1958], No. 14934/59. Class 39(3). A terminal seal for a heating element of the sheathed resistor type associated with a cooking vessel comprises a resilient, e.g. silicone, washer 13 and a cup-shaped, e.g. glass, bushing 16 surrounding the terminal portion 6 of the resistor 3, a terminal pin 21 being fixed to the terminal 6 and maintaining the washer 13 under compression between the end surface 7 of the sheath 5 and the inner end surface 14 of the bushing.

Patent GB-407568-A (GB)
Title: Improvements in valve mechanisms for controlling the supply of gaseous or liquid fuel to burners
IPC: F23N5/02
Filed: 1933-05-26
Abstract: 407,568. Safety cut-off valves. RUDD MANUFACTURING CO., 2934, Smallman Street, Pittsburg, U.S.A. May 26, 1933, No. 15262. Convention date, May 3. [Class 135.] Relates to valve mechanism for controlling the supply of gaseous or liquid fuel to burners of the kind comprising self-closing cut-off valves associated with a main and a pilot burner, and a heat responsive device for holding these valves open when the pilot flame is burning, and for causing them to close if this flame is extinguished. According to the invention a device is provided, operable simultaneously with a main valve in the fuel supply line to said burners, for temporarily opening only the pilot cut-off valve independently of the heat responsive device. In the form shown, the pilot and main cut-off valves S, 9 are maintained open during normal working by a bimetallic strip 57 heated by the pilot burner 3. If the pilot burner is accidentally extinguished the strip 57 unbends and allows both valves to close. The supply of fuel to the burners is controlled by a handcock 7, which, after the first quarter turn from closed position, admits fuel from the inlet 13 to the casing 46 of the valve 8 through a hole 20 in the inlet casing, a registering groove 21 in the cock 7, and a pipe 14. At the same time, the cam 26 on the cock pushes to the right a pin 27 slidable in lugs on the main casing against the action of a spring 30. The pin 27 raises a latch 33 so that its end engages the bimetallic strip and bends it sufficiently to open the valve 8, the valve 9 remaining closed owing to play between it and the stem 45 of the valve 8. The pilot burner is then lit. The second quarter turn registers the opening 18 on the cock with the inlet opening 17, thus supplying fuel to the casing 34 of the main cut-off valve 9 while still maintaining the pilot supply. The leg 56 of the bimetallic strip has now moved sufficiently to the right to open the valve 9, and also allows the latch 33 to fall to its original position.

Patent GB-498036-A (GB)
Title: Improvements in and relating to the fastenings of doors or gates of lift systems
IPC: E05B65/00
Filed: 1937-06-02
Abstract: 498,036. Locking lift gates &c. WAYGOOD-OTIS, Ltd., and IRWIN, E. G. June 2, 1937, No. 15297. [Class 78 (iii)] A locking device for well doors comprises a switch in the control circuit of the lift which is opened and held in open position prior to the complete release of a door-locking catch from the path of the door beak when the said catch is displaced by means such as a retiring cam on the lift, and auxiliary switch means in the said control circuit which is opened and closed as the door is opened and closed. In the embodiment shown the door beak 4 is held locked in a casing 1 secured to the door framework by a catch 5 pivoted at 6. When the cage arrives at a floor, the retiring cam engages a roller arm on the shaft 16 so as to pivot the catch 5 from its locking position.. Prior to the completion of this movement, a pin 18 on an extension 17 of the catch tilts a switch member 20 pivoted at 21, to open contacts 25 in the lift control circuit and lock the member 20 in this position, Fig. 3. On withdrawing the beak 4, a switch member 33 is pivoted by a spring 36 to open contacts 38 of an auxiliary switch in the control circuit. A spring-controlled latch 29 pivoted at 30 prevents the return of the catch 5 to its locking position, having a rib 28 which lies in the path of a projection 27 on the catch. When the door is again closed, the beak 4 engages the lever 33 to close the contacts 38, and pivots the latch 29 to an inoperative position. On operation of the appropriate push button, the circuit of the retiring cam is completed and the cam retracted. The catch 5 is then moved to its latching position by the spring-pressed plunger 11, and the pin 18 moving along the surface 19 to the recess 22, tilts the member 20 to close the contacts 25 and re-establish the control circuit. The movements are co-related to ensure that the catch 5 engages with the beak prior to the closing of the contacts 25.

Title: Improvements relating to the operation of blast furnaces
IPC: C21B5/00
Filed: 1962-04-24
Abstract: In the use of liquid petroleum products or natural gas as supplementary fuel in a blast furnace, these fuels are first cracked outside the furnace by partial combustion with hot air (which may be enriched with oxygen) under conditions such that the maximum amount of soot is formed, and the products are then charged to the furnace. Preferably the soot, together with a small amount of the gaseous products as carrier, is injected into the hearth with the blast, the bulk of the gas being introduced into the shaft.  Any surplus gas may be used elsewhere as a fuel. Cracking may be carried in regenerative chambers heated by oil or blast furnace gas, or in one or more cyclones.
