摘要： A sheet metal working or other press is operated say pneumatically. Movement of the press moves a freely rotatable screw relative to a freely rotating nut of a screw-and-nut mechanism so both spin in opposite directions storing energy which is released when the movement of the press is arrested during deformation of the workpiece. Either the screw or nut moves with the movable part of the press and the other is immovable in a casing. No rotary impact couples are transmitted to the frame of the machine when the press is arrested.

摘要： A self-advancing mine roof support has a first or main roof supporting member and a second roof supporting member movable relatively to said first roof supporting member in the direction of advance of the support. The second roof supporting member has laterally extensible means on elements for abutting similar extensible means or elements or an adjacent support. The abutting means or elements serve to guide the supports during their advance and also prevent the caving of the roof between adjacent supports. Conveniently the second roof supporting member constitutes a connecting element for connecting a roof-engaging member, at the forward part of the second roof supporting member, to the first or main roof supporting member, the first or main roof supporting member having guiding and pivotal supporting means for the second roof supporting member or connecting element. Conveniently the second roof supporting member or connecting element is of shieldlike construction so that, in conjunction with a shield-like construction of the rear of the base of the support, it prevents mineral flushing into the support. The second supporting member or connecting element may be supported on a prop which is tiltable towards the mineral face so as to advance the second roof supporting member.

摘要： A traction carriage for a cable railway having a traction cable off-set from the centre line of the track has two track-engaging trolleys connected by a beam which extends longitudinally of the track. A boom projects laterally from the beam adjacent to one trolley and a traction arm is pivotally mounted on the boom for movement relative thereto about a vertical axis which extends through the traction cable. The traction arm is connected to the cable and is so linked with the adjacent trolley that the portion of cable to which the traction arm is connected is maintained parallel to the centre line of the track.

摘要： A mine roof support for use at a mineral face has a flushing screening shield arranged on its goaf side. The screening shield is in at least two parts one being an upper part and another a lower part, the parts being hingedly connected together by a hinge means having its axis lying in the longitudinal direction of the mineral face. The upper shield part is hingedly connected to the upper or roof-engaging structure of the support, preferably by a universal joint, and the lower shield part is hingedly connected to the base or lower part of the support by a hinge having its axis transverse to the longitudinal direction of the face. Thus, the screening shield is additionally pivotally movable laterally relatively to the support. In one preferred embodiment the axis of the hinge, connecting the lower screen part to the base or lower part of the screen, lies parallel to the floor of the mine and, when viewed from the longituidinal direction of the mineral face, is disposed approximately centrally of the support.

摘要： A mine roof support for use at a mineral face comprises at least one prop, a canopy or roof-engaging structure adapted to lie against the roof of a mine working, a base member adapted to lie on a floor of said mine working, and a shield flexibly connecting, by hinge means, said canopy or roof-engaging structure and said base member. Said hinge means have their axes lying in the longitudinal direction of the mineral face and the hinge means connecting the shield to the base member is constructed so as to provide additionally for movement of the shield laterally relatively to the base member. In one preferred construction the axis of said hinge, which as stated lies in the longitudinal direction of the mineral face, is itself pivotable about an axis lying in the advancing direction of the roof support. The hinge connecting the shield to the canopy or roof-engaging structure may be similarly constructed. The shield may be constructed and arranged so that it will transfer, at least in part, the support forces between the roof and floor.

摘要： A press of the type wherein energy is stored in a rotating flywheel during the working stroke and released at the end of the stroke to perform work on a workpiece has a cylindrical housing acting as a drive cylinder for the press and also as a guide for a support adapted to carry a movable press tool. A nut and screwed spindle cause rotation of the fly-wheel and this nut and screwed spindle are also in the housing. The press is pneumatically operated for preference, with the return stroke by spring and/or pneumatic means. The support guide has a sealing ring which seals an annular lubricating oil chamber between the housing and the support. An oil mist can be injected into the compressed air used for the drive cylinder. The invention is particularly concerned with the operating assembly for the press which is a sealed well lubricated unit which can be attached to a variety of base assemblies to form different forms of presses.

[Also in Division H1] A headlamp comprises a two-filament halogen bulb having a dipped beam filament 7 located in front of the focus 6 of the reflector and a main beam filament 8 located behind the focus, and a screen 9 having a first semi-cylindrical portion 12 disposed below the filament 7, a second semicylindrical portion 13 disposed above the filament 8, and a connecting web 11, the screen being of such a form that it has a Z-shaped configuration when projected on to a vertical plane. The screen may consist of a coating on the bulb or a separate sheet-metal member placed around the bulb, and the edges of the web 11 may lie in vertical planes, as shown, or be rearwardly inclined from top to bottom.
