Abstract: SPECIFICATION          EUGENE V. ABAROTIN AND MICHAEL A. BUCKISO BITS FOR INGOT TONGS                 ABSTRACT OF THE  DISCLOSURE           Improved bits for ingot tongs, an improved tong-and-bit combination, and an improved method of handling ingots.  The bits are formed of a durable metal, such as a nickel alloy or a cobalt alloy, and are rotatably fastened in the tong arms.  Protrusions from the outside faces of the tong arms are avoided to prevent damage to parts struck by the tongs.  The distance by which the points s on the bits protrude from the inside faces of the tong arms can be adjusted for different sized of ingots.  The method includes a step of rotating the bits through a small arc each time an ingot is set down, whereby a fresh area is presented upwardly after each use and wear on the bit point is distributed around the circumference.

Abstract: ABSTRACT       Hydrometallurgical process for the recovery of copper arsenate from zinc plant cement copper cake residues and the use thereof in the purification of zinc electrolyte, with the attendant upgrading of the copper value in the treated cement copper residues.  The cake residues are first subjected to an acid leach followed by an alkali addi?ion to adjust the pH of the slurry to about 3.5 to 4.0 and to extract zinc, cadmium and cobalt in solution and provide a copper-enriched residue.  Cobalt is then precipitated and separated from the extraction solution.  The copper-enriched residue is subjected to caustic leach to extract arsenic in solution therefrom and provide a copper-enriched cement copper cake product.  The arsenic containing extraction solution is then reacted with a copper salt to form copper arsenate residue and leave purified zinc electrolyte.

Abstract: ABSTRACT:        A device for an automatic record player in which the pick-up arm movements during the changing cycle are controlled by a command disc in which grooves are formed for a sensor pin which is connected to the pick-up arm, one of several substantially concentric slots being the pin-catching slot for a specific record size,  and the pin being directed into the desired pin-catching slot by a mechanical catching means, whilst during the rotation of the command disc during a changing cycle the pin which is made resilient perpendicular to the sensing surface, in a manner known per se, engages with a bottom groove of a slot which directs said pin substantially in the direction of the disc centre, and the pin jumps out of the groove when the inward movement is mechanically stopped and engages with the pin-catching slot for the relevant record size or for the stop function, for which purpose the inward movement is stopped by a blocking member, which blocks the path of the pin.

Abstract: TENSION BRIDLE                 ABSTRACT OF THE DISCLOSURE      The disclosure relates to a multi-roll tension bridle for hot and cold rolled steel strip, in which at least the first roll of the bridle is provided with an internally mounted normally non-rotating electromagnet for causing the strip to be attracted against the entry portion of the roll in order to create a pretensioning in the portion of the strip immediately adjacent the entry side of the bridle, thereby causing the bridle drive motor to load up preventing slippage of strip on the roll.           The tension bridle as employed in the steel industry, as for example in continuous tension levelling side trimming processing lines, are sometimes placed in the line in a position where the strip coming to the bridle is under little or no externally applied tension. In order for the tension bridle and more specifically the first roll thereof to effectively contribute to the desired total amount of tension producible by the bridle in the passing strip it was customary to provide a device to impose a pre-tension on the strip in the form of either drag boards, drag magnets, or a set of pinch rolls or bending rolls.

Abstract: ABSTRACT OF THE DISCLOSURE     A system is disclosed for the transfer of heat from an ambient heat sink of variable temperature to a conditioned space, said system being operable in a first mode when the temperature of the heat sink is at a relatively high level, and in a second mode when its temperature is at a relatively low level.  The system includes a first refrigerant circuit which is operable in said first mode as a heat pump of the vapor compression type to absorb heat from the ambient heat sink and transfer same to the conditioned space.  A second re-frigerant circuit is provided which is operable in the second mode, when the temperature of the ambient heat sink is at a relatively low level, to absorb heat from the ambient heat sink and transfer same to the first refrigerant circuit, which when transfers the heat to the conditioned space.  Thus, in second mode operation, the first and second refrigerant cir-cuits operate in a "cascade" relationship.  Suitable control means are disclosed for effecting operation of the system as described above, and, in addition, a suitable method of operation for such a system is disclosed.

Abstract: Abstract A burst gate pulse generating circuit includes a normally saturated transistor (60) responsive to a pulse (Vs) representative of a horizontal sync component of a video signal which includes a burst interval.  The sync pulse is coupled to a base input of the transistor via an RC differentiating network (52, 56, 58) for causing the transistor to operate between saturated and cut-off states, such that a gate pulse (Vo) produced at the transistor collector output is delayed relative to the sync pulse and substantially coincides with the burst interval. The circuit is arranged so that the sync pulse as coupled via the differentiating network (52, 56, 58) causes the base-emitter junction of the transistor to break down in the reverse direction.  The timing of the output gate pulse is therefore substantially independent of they sync pulse amplitude, which can vary undesirably, thereby promoting accurate pulse timing.
