Title: Improved apparatus for applying coverings to weldrods
IPC: B23K35/40
Filed: 1934-10-27
Abstract: 440,842. Extrusion machines. ARNOLD, C., 11, Southampton Buildings, Chancery Lane, London.-(Lincoln Electric Co. ; 12818, Coit Road, Cleveland, Ohio, U.S.A.) Oct. 27, 1934, No. 30878. [Class 87 (ii)] Apparatus for applying coverings to welding rods comprises mechanism for successively forcing core rods 11 in alignment, end to end and abutting against one another, through an extrusion machine 3 and means rendered operative by the issuing welding rod for removing the covering from a terminal portion of each rod. A feeder rod 6 reciprocated by a piston 7 forces rods 11 from a magazine 1 through a conveyer tube 5 into the machine 3 and a coating of material 14 fed as by a screw conveyer 15 is applied by extrusion through a nozzle 13. As each rod issues from the machine, it abuts against a reciprocable rod 16 mounted in a casing 17 and normally, urged towards the nozzle 18 by a spring 18. The rod 16 is formed with a soft-iron armature 27 and the casing is surrounded by an electromagnet 19. Cam tracks 21 are fixed to the casing 17 to operate arms 23 pivoted on a cross-head 22 fixed on the rod 16, the arms 23 being formed with curved blades 24 adapted to strip the covering from the terminal portion. In use, as each rod 11 issues from the machine 3 such rod pushes back the rod 16 until a pivoted switch arm 29 connected thereto by a spring 33 is swung over to energize the magnet The rod 16 is then moved quickly into the casing and the arms 23 operated to strip the covering, after which the rod 16 through a spring 37 actuates a switch arm 36 to break the circuit. The rod 11 still pushes on the rod 16, but finally drops away and allows the rod 16 to spring back, the springs 33, 37 re-setting the switch arms 29, 36. In a modification the die 13 of the extrusion machine is fitted with an attachment having radially movable jaws for removing the covering from a terminal portion of each welding rod. A rotatable disc mounted within an apertured casing is provided with a cam slot wherein work pins on the radial jaws which slide in grooves in the casing. As a result, movement of the disc causes the jaws to come together and define an aperture adjacent to, but smaller than, the extrusion nozzle, so that the covering is removed from the rod at that part. The disc is rotated by lever mechanism operated by a further electromagnet. The covered rods successively engage a spring-loaded reciprocable rod which actuates or engages switches for making the separate electromagnet circuits and for breaking both circuits simultaneously. Specification 13656 /00, [Class 87], is referred to.

Title: A method of and means for ventilating underground workings
IPC: E21F17/103
Filed: 1955-11-04
Abstract: 772,412. Ventilating. LITWINOV, N. Nov. 4, 1955, No. 31618/55. Class 137 In a method of ventilating blind underground workings; e.g. a tunnel 2, poisonous gases, generated by explosion, are evacuated from near the working face 1 by using a light dismantable screen 8 which acts as a piston as it is moved, e.g. by a truck 7, along the tunnel at a rate corresponding to the speed of evacuation of poisonous gases, and which is used in conjunction with an air pump which creates a slight depression, or overpressure on one side of the screen. A valve box 70 for a compressor 4 is set to supply compressed air through a pipe 3 to tools for drilling holes for explosives in the face 1. After an explosion the truck 7, fitted with the screen 8, is pushed to a point 6 corresponding to the maximum spread of contaminated air from the face 1, the valve box 70 of the compressor 4 being adjusted so that the suction duct of the compressor is connected with the pipe 3 to produce a vacuum and suck away the contaminated air near the face 1. The truck 7 and screen 8 are meanwhile slowly advanced toward the face 1 at a speed corresponding to the rate of evacuation of contaminated air. If the appropriate speed of the screen 8 is-maintained, as computed from the volume of contaminated air between the points 6 and 1 and the exhaustive capacity of the compressor 4, no substantial leak of air occurs in either direction past the screen, however since the miner pushing the truck must always stay in fresh air he should allow a small escape of fresh air toward the face 1. The screen 3, made e.g. of plywood, or light metal, and shaped to correspond to the section of the tunnel 2, is provided, around its edge, with an elastic fringe 9 which is made e.g. of overlapping plastic sheets 91 to closely fit the tunnel 2 and yet move over 'obstructions such as timbers 41, pipes, rails, &c. The screen 8, which may have a fringe made from a single piece of elastic material, can be used in horizontal, inclined, or vertical workings, and may be mounted on any other type of vehicle or on e.g. a cage or skip. In an alternative method fresh air is supplied through the pipe 3, which may be replaced by a wider pipe equipped with a fan, not shown, to the space near the face 1, he truck 7 and the screen 8 being: moved away from a position 10 while a steady overpressure of fresh air is maintained between the screen 8 and the face 1. While pushing the truck and screen to the position 10, immediately after an explosion, the miner should wear a gas mask.

Abstract: 1,175,959. Latches. MECO N.V. 5 July, 1968 [6 July, 1967], No. 32256/68. Heading E2A. A lock comprises a fore-end 5, a stop means 22, a latch bolt 1 and a follower 16, wherein the latch bolt I can slide from a retracted position to a first forward position in an aperture 4 in the fore-end 5, the first forward position being determined by abutment of the follower 16 against the stop means 22 which is manually movable to a release position which allows the latch bolt 1 to move to a second forward position beyond the first forward position, rotation of the latch bolt about its longitudinal axis being prevented in its retracted and first forward positions, but permitted when in the second forward position. As shown the latch bolt 1 has a head 2 of hexagonal cross section at its forward end and of circular cross section at its rearward end by which it is connected through a peripheral groove 7 with a bolt tail 10 slidably mounted on pins 13, 14 in the lock case. The bolt is operated by the follower 16 to withdraw the bolt against springs 17, 18. The stop means 22 consists of one arm of a lever 20 pivoted on a pin 19 and having a manually operable arm which projects through an opening in the fore-end of the lock, such that when the arm is depressed to the position shown in Fig. 6, the stop means 22 releases the follower 16, and allows the bolt to be projected further beyond the position where its hexagonal head part is normally slidably engaged with a hexagonal hole in the fore-end of the lock. In this projected position the head may be rotated to change the hand of the latch, after which normal operation of the follower 16 to withdraw the latch bolt restores the lever 20 to its initial position.
