Abstract: ABSTRACT OF THE DISCLOSURE         A scroll-type compressor unit includes a fixed and orbiting scroll members contained within a cylindrical housing.  Each scroll member has an end plate and a spiral element.         In order to reduce the radius of the cylindrical housing, the end plate of the orbiting scroll member is a circular plate having a radius of (a - R/2), and the center of the end plate of the orbiting scroll member is offset from the center of the spiral element affixed thereto, assuming that the radius of the orbital motion of the orbiting scroll member is R, and that the distance between the center and the terminal end of each spiral element is a.         Furthermore, the fixed scroll member is so disposed in the cylindrical housing that the center of the spiral element thereof is offset from the center of the cylindrical housing towards the terminal end of the spiral element thereof by R/2. In this arrangement, the radius of the cylindrical compressor housing is further reduced.

Abstract: ABSTRACT: "Counterbalanced support"     A counterbalanced support, for example, for supporting the patient or radiation source in X-ray diag-nosis or therapy, comprises a supporting frame (3) movably mounted on a base (2) by means of a parallelogram linkage (1). This linkage comprises two parallel rods (20 and 21) which are pivotally connected to the supporting frame and the base and one of which is formed with an arm (26) to which a constant force is applied for counterbalancing the weight of the supporting frame and its load. This force is supplied by a pneumatic pulling device (37, 38) via means (36, 39) which are freely movable in the base so that a substantially constant pulling force is exerted on the arm (26) in a direction which extends at a fixed angle to the vertical.

Abstract: ABSTRACT  OF DISCLOSURE         This invention relates to a method of making steel in a bottom-blown converter from a charge of solid metallic iron-?aring materials wherein the charge is melted down without an addition of liquid pig iron in order to avoid uncontrolled flow conditions with the aid of burners which form a molten sump, fine-particled carbon and oxygen being separately injected into said sump through tuyeres which are disposed below the burners.  The burners may be sited either slightly above the final upper surface level of the melt or below said level, and in the latter event the burners may be operated as additional tuyeres after they are submerged in the melt.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention discloses a process for producing a bar of soap which consists of a main piece of soap and at least one secondary piece of soap which is embedded in the surface of the main piece of soap.  Both the main piece and the secondary piece are extruded at about 35°C to about 45°C and then the secondary piece is cooled to between 25°C and 35°C before being embedded in the main piece.  This causes the main piece to flow around the solid secondary piece which produces a tighter bond between the two pieces.  An attractive product which can be produced on a commercial scale is produced which has hithertobefore been unknown.

Abstract: Abstract of the disclosure The invention relates to a method of carbonating green liquor and seprating sulphur from this liquor as hydrogen sulphide. Green liquor is prepared by burning the waste liquor from chemical pulping process in a recovery furnace or with corresponding method and dissolving the smelt obtained in aquous solution. Green liquor is first clarified in order to separate insoluble solids and possibly precarbonated with gas containing carbon dioxide. Then green liquor is carbonated with concentrated carbon dioxide so that proper concentration of alkalibicarbonate is obtained for separating sulphur as hydrogen sulphide in the following stage. In sulphur separating stage, alkali bicarbonate and alkali bisulphide react with each other liberating hydrogen sulphide.

Abstract: Abstract of the Disclosure A composition and a method for applying a lubricant coating to clean metal surfaces prior to subjecting them to metal forming operations.  The composition comprises a con-centrate which is adapted to be diluted with water, if desired, to produce an aqueous acidic operating bath containing a con-trolled effective amount of phosphate ions to form a phosphate coating on the clean metal surface in combination with an emulsified organic lubricant agent, an emulsifying agent and an aqueous soluble organic corrosion inhibiting agent.  The coating composition may further optionally contain a controlled amount of heavy metal cations for activating the coating bath. The coating composition is applied to a clean metal surface such as by flooding, immersion, spraying, or the like, at temperatures from ambient up to about 200°F for a period of time sufficient to effect a desired coating magnitude where-after the parts are dried, preferably at elevated temperatures before forming.

Abstract: T&B 840 ABSTRACT OF THE INVENTION:          A liquid- tight connector for joining a jacketed flexible metal clad cable to an electrical enclosure with a continuous ground path between the cladding and the en- -closure. To a standard body gland nut arrangement is added a sealing ring and a grounding ring effectively operated to grip the cable jacket and metal cladding respectively as the gland nut is tightened upon the body.  Reduction of the sealing ring bore to cause the ring to grip the cable jacket is accomplished by an undercut in the ring wall and a dual outer diameter arrangement which deforms the sealing ring as its enlarged portion is forced into the body bore and as the ring is compressed between the gland nut and stops on the grounding ring.  The sealing ring further operates the grounding ring whose upstanding arms are moved and deformed into intimate contact with the metal cladding of the cable. Supports on the arms assure proper displacement of the arms while stops insure proper compression of the sealing ring.

Abstract: ABSTRACT             A component consisting of two coupled PTC thermistors, the first thermistor having a lower cold resistance than the second thermistor and the first thermistor having a higher resistance at the operating temperature than the second thermistor.  According to the invention, the electric connection to the second thermistor is made directly by solely mechanical contacts to the surface of the ceramic thermistor body.  This means a considerable simplification during manufacture, as the second thermistor need not be provided with electrode layers.
