Abstract: 11                       47,714 ABSTRACT OF THE DISCLOSURE A metal halide high-intensity discharge lamp for connection  to  a  constant  wattage-type  mercury  ballast including a transformer having a secondary winding having a capacitor in series circuit arrangement therewith.  The lamp includes starting aid means and warm-up assistance means  to  ensure  reliable operation.   The  starting aid means  is  a voltage doubler comprising, a diode and two resistors operating in conjunction with the ballast capa-citor and also including a normally closed heat-responsive switch means operative to prevent voltage stress on the diode after the lamp starts.  The warm-up assistance means comprises a resistor in series circuit arrangement with the arc tube and a normally open heat-responsive switch means connected in parallel circuit arrangement with the resistor so that during lamp warm up, the resistor reduces the phase shift between the voltage of the lamp and the open circuit voltage of the ballast, thereby increasing the maximum sustaining voltage to the lamp when the lamp current is zero, to prevent the arc from extinguishing.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a permanent memory structure supported by a moving substrate.  This sub-strate is formed by two metal layers (9, 10) vacuum-deposited on the relatively inexpansible substrate (1). One of the two metal layers is very expansible (9), whilst the other layer (10) is relatively inexpansible, but ductile.  During inscription by the laser beam, the beam energy absorbed by the layers (9, 10) produces an elongation of the expansible layer (9), which deforms the ductile layer (10) by stretching it beyond the elastic limit.  There is a permanent deformation of the two-layer assembly, without perforation.  Particular application to optical disks.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an amphoteric resin obtained by condensation of polyethylenepolyamine and butene-1,2,3,4-tetra-carboxylic acid.  The present invention can provide several forms of amphoteric resins such as linear structure, somewhat cross-linked water rinsoluble and water swellable structure and water insoluble and cross-linked structure, since the resin contains in its repeating units an imino group, a carboxylic radical and an amido group.  The resin can form chelate with several kinds of metal ions.  Furthermore, the resin can also be modified by introducing several kinds of functional groups to bestowed the resin with particular chelating ability.  Therefore the invention can provide novel resins, which have a strong chelating faculty and are suitably used as removing and recovering agents of heavy metals and novel metals.

Abstract: ABSTRACT OF THE DISCLOSURE   A data processing system which handles thirty-two bit logical ad-dresses which can be derived from either sixteen bit logical addresses or thirty-two bit logical addresses, the latter being translated into physical addresses by unique translation means. The system includes means for decod-ing macro-instructions of both a basic and an extended instruction set, each macroinstruction containing in itself selected bit patterns which uniquely identify which type of instruction is to be decoded.  The decoded macro-instructions provide the starting address of one or more micro-instructions, which address is supplied to a unique micro-instruction sequencing unit which appropriately decodes a selected field of each micro-instruction to obtain each successive micro-instruction.  The system uses hierarchical memory stor-age using eight storage segments (rings), access to the rings being con-trolled in a privileged manner according to different levels of privilege. The memory system uses a bank of main memory modules which interface with the central processor system via a dual port cache memory, block data transfers between the main memory and the cache memory being controlled by a bank con-troller unit.

Abstract: ABSTRACT OF THE DISCLOSURE    A rock anchoring arrangement for use especially in tunnel and mine constructions involving considerable convergences comprises an anchoring sleeve having a leading and a trailing end as considered in the direction of introduction of the anchor-ing arrangement into an anchoring bore in the rock formation, an anchoring rod having a trailing end portion passing through the interior of the anchoring sleeve and a leading end portion which extends beyond the leading end of the sleeve, a mounting plate arranged at the trailing end of the sleeve for engaging the support structure around the open end of the bore, and a drawing die secured to the sleeve at the leading end.  The anchoring sleeve and the anchoring rod are both adapted to be retained in the bore by a body of a hardenable material, such as an adhesive, in which the sleeve, and the leading end portion of the rod are eventually embedded. The leading end portion of the rod has a smaller diameter than the trailing end portion so that a transition region exists between these portions.  The drawing die has an aperture which receives the leading end portion and, when pulling force acts on the arrangement, acts on the transition region to deform the same when the magnitude of the pulling force is at a predetermined level and thus to increase the axial length of the anchoring rod. The aperture is either conical throughout, or includes alternating conical and cylindrical zones.

Abstract: ABSTRACT OF THE DISCLOSURE     A synchronizing signal generator includes a tape recorder which is adapted to record click signals in res-ponse to actuations of a manual switch.  Clock signals are then recorded during reproduction of the recorded signals, especially during a length of time from receipt of a par-ticular one of the click signals to receipt of the next succeeding click signal.  The resultant count is divided by a given numeral value and then the quotient is stored.          The clock signals developing between the respective click signals are again counted during the course of reproduction of the click signals from the tape recorder and a pulse signal is delivered whenever the instantaneous count agrees with the stored quotient.  Tempo clock signals are obtained through the division of the pulse signal at a selected division ratio.  The tempo clock signals are fed to a sequencer which in turn generates a control voltage and gate signals synchronous with the tempo clock signals. A music synthesizer produces tone signals in synchronism with the tempo clock signals in response to the control voltage and the gate signals.

Abstract: A METHOD OF RECOVERING HEAVY OIL FROM A SUBTERRANEAN, PERMEABLE, HEAVY OIL-CONTAINING FORMATION            Abstract of the Disclosure A method of recovering heavy oil from a subterranean, permeable, heavy oil-containing formation comprises injecting steam into the lower portion of the formation, injecting a controlled amount of unheated water into the upper portion of the formation and displacing the oil through the formation towards a production well where the oil is recovered.  The steam injection releases heat to the heavy oil and formation reducing the viscosity of the oil and increasing its mobility for recovery.  The unheated water improves the oil recovery per BTU injected by scavenging heat from the steam heated formation so as to increase the volume of the formation subjected to heating and by diverting the flow of steam through the formation so as to increase the vertical sweep.
