Abstract: ABSTRACT OF THE DISCLOSURE     For the production of strip material particulate metalliferous material is fed from a hopper into and through the roll gap formed between a pair of contra-rotating compaction rolls.  The ends of the roll gap are closed off by means of endless belts which engage the opposite end faces of the compaction rolls and in order to counteract the tendency of particulate material to be drawn into the end zones of the roll gap by the endless belt means are provided for restricting the flow of particulate material to these end zones.  By the provision of such restricting means the rate at which particulate material enters the roll gap is substantially uniform alone its entire length.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for eliminating under-etchings.  In a substrate having a lower silicon dioxide layer thereon, a polysilicon layer on the silicon dioxide layer, and an upper silicon dioxide layer on the polysilicon layer, an etched window provided in the layers has first under-etchings formed at an edge of the lower silicon dioxide layer adja-cent the substrate and a second under-etching formed at an edge of the polysilicon layer.  A sputtering source is provided with a given target voltage.  A grid potential is applied to the substrate wherein the grid potential is between one-tenth and one-third of the target voltage.  A layer is then sputtered on in the etching window for filling in the first under-etching by re-emission from the surface of the substrate and for sloping the edge of the polysilicon layer at the second under-etching.  An over-hanging portion of the upper silicon dioxide layer is also removed at the second under-etching by re-emission during the sputtering on.

Abstract: ABSTRACT OF THE DISCLOSURE     A tower is installed at an offshore worksite by floating to the worksite a tower subassembly which comprises a base, a plurality of upright open-trussed initial leg segments, and a plurality of flotation tanks. A plurality of open-trussed add-on leg segments are stored on a vessel in the vicinity of the worksite. The flotation tanks are ballasted to partially immerse the subassembly so that buoyant jacking units disposed within and connected to respective ones of the initial leg segments floatingly support the subassembly, with top portions of the initial leg segments projecting above the water surface. Add-on leg segments are mounted onto the leg portions projecting above the water surface. While the subassembly is suspended from the jacking units, the subassembly is lowered so that the jacking units enter the add-on leg segments as the add-on leg segments pass downwardly therearound. These steps are repeated so that the subassembly is gradually built-up with leg segments and is progressively submerged. When the base is supported on the sea floor, the jacking units are lifted from the top ends of the tower legs. A work platform is then installed on the tower legs above the water surface.

Abstract: This invention is for controlling the energization of a furnace, air conditioner or the like that has two thermostats, one to control the upper temperature limit and the other to control the lower temperature limit. A manually settable programming means is provided that is operable on a continuous basis from the voltage across thyristor devices associated with the thermostats which control the on-off condition of the furnace.  The programming device divides time into slots and has a switching means that enables a thyristor of a selected one of control paths to conduct when its respective thermostat is closed and to disenable the thyristor of the other control path from conducting in any predetermined time slot.  Power for operating the programming device is obtained from the voltage across the thyristors when they are conducting and when they are non-conducting.

Abstract: TITLE: LIQUID HEATING AND CIRCULATING SYSTEM       Abstract of the Disclosure A method and apparatus for maintaining equipment, such as an engine, in readiness for use while it is otherwise nonoperational. The equipment or engine is of the type having a closed liquid recirculation system.  The present method and apparatus bypasses the usual recirculating pump in this system.  An external supply pump removes liquid from the system sump or reservoir, and diverts the liquid from passage through the normal recircu-lating pump of the recirculating system.  The diverted liquid is conditioned to a predetermined temperature by passage through a heat exchanger.  It is pressurized by operation of the supply pump.  It is then redirected into the equipment recirculation system downstream from the outlet of the system's recirculating pump.  The pressurized  and temperature conditioned liquid is then forced through the equipment passages in the recirculation system. This maintains the equipment at a temperature in readiness for use.  In the case of a lubrication liquid system, it also maintains proper lubrication of the equipment elements during periods in which the equipment is not being used.

Abstract: Abstract Safety belt assembly including a redirecting device for a safety belt for use in motor vehicles, in which one end is rolled up on an automatic winder and the other end of the safety belt has a fitting for connecting the belt to a lock.  The redirecting member is a hollow rotatable cylindrical member, wider than the belt, mounted on an axle supported by the legs of a bracket. Roll elements are disposed at the ends of the cylindrical wall of the rotatable member to support it and permit it to rotate freely. Additional roll elements which project beyond the wall of the rotatable member are disposed in the central region of the rota-table member.  This has the advantage of a smaller ratio of retraction force to pull-out force of the belt.
