Title: Surface treatment of superconducting niobium-tin alloys - by subjecting to anodic oxidn., and then removing oxide layer
IPC: H01L39/24
Filed: 1975-05-26
Abstract: Properties of superconducting Nb3Sn surfaces, esp. for alternating current uses, e.g. of cables and resonators, are improved by (a) applying an oxide layer to the surface by anodic oxidn., and (b) chemically dissolving the oxide layer. gives a smooth Nb3Sn surface that is free of impurities, and has a low surface resistance. Alternating current losses in the surface are reduced, and superconducting properties improved.

Title: Removing phosphorus from metals or alloys - by treating melt with compsn. contg. calcium carbide and alkaline earth metal halide
Inventor: KATAYAMA HIROYUKI
IPC: C22B9/00
Filed: 1976-06-30
Abstract: Phosphorus is removed from metals or alloys esp. from iron melts contg. metal(s) which can be oxidised more readily than iron, by adjusting the carbon content to a value below the satn. limit, and treating the melt (I) in a non-oxidising atmos. with a P-removing compsn. (II) based on CaC2 (3-90%) and >=1 alkaline earth metal halide (>=10%). The compsn. (II) may contain 3-50% of Ca and/or its alloy (calcd. as Ca), pref. Ca-Si, Ca-Si-Mn and/or Ca-Si-Fe. The method is esp. suitable for P removal from Cr steels, in which P adversely effects the corrosion resistance, workability and weldability. CaC2 decomposes, and Ca reacts with P forming Ca3P2 which passes into the slag; whilst C dissolves in the Fe (the latter must be unsatd. w.r.t. carbon). The process is rapid and economical.

Title: Press tool and mandrel combination for forming containers - with thermoplastic tops, involving simple, robust components which can work in gangs
IPC: B29C33/00
Filed: 1976-10-15
Abstract: Flexible tubes involving a combination of a tubular body and a moulded top with an integral threaded neck are made by supporting the sleeve at a low level on cylindrical mandrel taller than the sleeve while a preform of thermoplastic material is heat softened while supported on the top of the mandrel. The sleeve is then raised until standing sufficiently proud of the shoulders of the mandrel to be turned in by a press tool which is simultaneously reshaping the soft preform into a top and neck for the container. The tubular body is sufficiently remote from the top of the mandrel to not require shielding while the thermoplastic preform on top of the mandrel is heated. The equipment is very simple and robust. Several mandrels can be serviced by multiple cam-lift mechanisms and press tools working in unison.

Title: Machine tool control system - uses electromagnetic probe registering bit placement without contact
IPC: G01D5/20
Filed: 1976-11-26
Abstract: The electro-magnetic machine tool control system positions and orientates a drill bit (8) cutting angles in the formation of gear teeth.

The control assembly for the loading, location and rotation of the bit (8) has a motor driven (36-40) rotating spindle (30) in a mounting block (32). The bit is loaded and axially aligned in the projecting axial extremity of the spindle (30) and is secured by a chuck (34) operated from the opposite spindle extremity (35). The detection equipment (53) with the probe, is a retractable assembly which registers the angular orientation of the bit and acts with an auto-read-out group. During its rotation, the bit (8) modifies the frequency of an oscillator coupled to the auto system. The probe has a 'U' shaped magnetic core with an induction bobbin and is mounted in the oscillating circuit.

Title: Two stroke IC engine - has cylinder separated from crankcase by partition to define compression chamber
IPC: F02F11/00
Filed: 1977-03-16
Abstract: The engine has a cylinder (4) which is closed at both ends (1, 2). Air is admitted through a port (7) in the end of the cylinder below the piston. After being compressed it is transferred by a passage (5) to the upper end of the cylinder where the expansion and exhaust strokes take place. The piston rod is guided in a sleeve (15) in the crank-cases where it is also pinned to the connecting rod. The separation of the bottom part of the cylinder from the crankcase reduces dilution of the fresh charge by burnt gases and increases the efficiency of the engine.

Title: Controls for regeneration of domestic and industrial water softeners - starts cycle after measured outflow and preset elapsed time
IPC: B01J49/00
Filed: 1977-04-18
Abstract: An automatic switch for starting a processing cycle at a preset time after a predetermined vol. of liq. has flowed through a flowmeter delivering electric impulses in proportion to vol. measured. The switch is of the type comprising a time switch which delivers a signal at a preset time. The switch comprises a counter for the electric impulses, a preselector for a set value of flow vol., a comparing circuit for the measured and set values of flow vol. which delivers a command signal to a first memory circuit when these values coincide. A second comparing circuit issues an actuating signal to start the cycle when it detects coincidence of a signal from the time switch with a commanded state of the first memory circuit. The time switch pref. comprises a digital clock. Used partic. to control the start of a regeneration cycle of an ion exchange water softening plant for industrial and domestic applications. Regeneration does not take place too soon as it may if initiated on elapsed time alone. On the other hand, regeneration starts soon after a predetermined vol. has flowed, so unsoftened water is not risked.

Title: Coil of metal foil made continuously - by vacuum vapour deposition, where each metal layer is sepd. by antiadhesion layer
Inventor: SHEVAKIN JURY FEDOROVICH
IPC: C23C14/00
Filed: 1977-06-06
Abstract: Rolls of metal foil (b) are made by continuous vacuum vapour deposition, where a rotating drum is coated with an anti-adhesion layer (a) onto which metal (b) is condensed. With the continuous rotation of the drum, the deposition sequence a,b,a,b,a,b,... is repeated, i.e. after each metal layer (b) is deposited another layer (a) is applied before the next layer (b). A roll or coil of metal foil is thus obtd. in which each turn of metal (b) is sepd. by a layer (a). Used esp. for the mfr. of pure metal foil with high quality and rapid prodn. An example is Al foil for the mfr. of Al electrolytic capacitors, where an exact microsurface is produced on the foil, improving the forming during capacitor mfr. and therefore the quality of the capacitors.

Title: Automatic washing of mechanical parts using solvents - the equipment having an automatic distillation regeneration circuit
IPC: C23G5/04
Filed: 1977-06-16
Abstract: The volatile and inflammable solvents used are recycled, after regeneration, by equipment forming an integral part of the washer. The total unit has (a) a washing unit with two mobile series of jets which move along the length of the area where the parts are put for cleaning and (b) a solvent regenerator functioning by distillation. Means for pumping heating and storing the solvent are included.
