Abstract: 381,808. Mine props. RICHARDS, F., 14, Brynheulog Street, Port Talbot, Glamorgan. Jan. 29, 1932, No. 2696. [Class '20 (ii).] Mine-prop caps are formed from sheet metal by stamping, and are shaped with continuous depending flanges which surround the head of the prop. The cap 2, Figs. 1 and 2, is formed with a continuous flange 1 which may be deeper at the corners where it engages the edges of the flanges of the section-metal prop, and the cap flange may be slit at these portions to make them resilient. Portions 12, Fig. 3, of the flange may be bent inwardly to engage a cross-pin 9 secured to the head of the prop, or the edge of the flange may be sprung 'outwardly to form a gripping portion for the head of the prop, or the edge may be welded to the prop end. A cylindrical cap may be pinned to the head of a tubular prop. A blank 24 shaped as in Fig. 9 may be used to form the cap, the parts 25 being bent under the prop end as shown at 26, Fig. 11, to engage between the flanges against a rivet 28. Specification 375,572 is referred to.

Filed: 1919-03-17
Abstract: 144,978. Fulton, E. W. March 17, 1919. Vices.-In a quick-adjustment bench vice in which the shank of the movable jaw can slide through the fixed jaw when tilted and is held by wedge-shaped locking members, the shank is pivoted about an adjustable bar having an inclined base, and the operating-screw for effecting fine adjustment is held in position by a collar located in the front of the movable jaw. The shank 4 carrying the movable jaw 21 can slide freely when tilted slightly, through an aperture 3 in the fixed jaw 1 and normally rests on a wedge-shaped fulcrum member 15, preferably of hardened material, arranged in an inclined recess in the bottom of the aperture and adjustable by a screw passing through the side wall of the aperture. The shank 4 has wedge-shaped grooves 5 with which engage wedge-shaped members 10 held by screws 13 in recesses in the walls of the aperture 3. The members 10 have clearance to permit of the free movement of the shank over the members 15 when tilted but act to lock it when released. Fine adjustment of the jaw is effected by a screw 7 engaging a threaded hole in the end of the shank and held to the jaw by a rib 18 on a segment collar 19 secured to a plate 20 which is fixed to the jaw. A set-screw 22 passing through the plate 20 into the shank limits the rearward movement of the jaw on the shank. The screw 7 can be lubricated through an oil-hole extending from the surface of the shank to the threaded hole. Specification 144,798 is referred to.

Abstract: 1,249,471. Roller punching. JOSEPH LUCAS (INDUSTRIES) Ltd. 8 Jan., 1969 [22 Jan., 1968], No. 3217/68. Heading B3W. A machine for trimming holes in a grid formed by roller punching comprises a roller 16 carrying an impression which corresponds substantially to the face of the grid presented to it and a roller 14 having projections which correspond to the interstices of the grid, the portions of the roller 16 corresponding to the interstices of the grid being formed by resilient inserts 18, the arrangement neing such that in use when a grid 11 is passed between the rollers it is received in the impression of the grid in roller 16 and the projections on the roller 14 enter the interstices of the grid severing any fillets of material therein. As shown, the depth of the recesses 15 in the roller 14 is greater than half the thickness of the grid and that of the recesses 17 in the roller 16 is less, by an amount equal to that by which the recesses 15 are deeper. If the fillets are nearer one face of the grid the recesses 17 need only be deep enough to support the grid with the fillets resting on the inserts 18. The peripheries of the rollers may merely be in contact or the projections on roller 14 may deform the inserts 18 during trimming. The inserts eject the severed scrap from the roller 16.

Title: Improvements in or relating to inverter circuits employing transistors
Inventor: BROWN THOMAS HENRY
IPC: H02M7/5383
Filed: 1957-01-30
Abstract: 815,668. Converting. MULLARD Ltd. Jan. 30, 1957, No. 3280/57. Class 38 (2). [Also in Group XL (c)] A transistor oscillator used for converting D.C. power to A..C. power is provided with protective means whereby power dissipation in the transistor is reduced if the oscillator is overloaded. The circuit comprises transistors T1, T2 arranged in push-pull with their collector and base circuits mutually coupled by means of windings P1,P2,F1,F2 preferably arranged on a common core so that in operation the transistors are alternately conductive and a squarewave output is developed in windings P1, P2. These are coupled to a further winding, Fig. 1 (not shown), from which the output is taken; if desired this winding may supply a bridgerectifier circuit to deliver a direct current output. The protective circuit includes diodes D2, D3 and transistors T3, T4, connected as shown. By virtue of the diodes the potential at A is the mean of the potentials at the collectors of transistors T1, T2 when in their " on " conditions. Considering transistor T1 to be conducting and transistor T2 cut off, point D will be positive with respect to earth and hence by diode action between the collector and base of transistor T4, point B will be sent sufficiently positive to cut transistor T3 off provided that the potential at A is also sufficiently positive; this is arranged to occur only when the transistors are " bottoming " during the oscillation cycle. Thus if such a load is placed on the circuit as to prevent bottoming, transistors T3, T4 become conductive, and the transistors T1, T2 cease oscillating and are finally held with their bases close to earth potential so that the current flow through them is small.
