This application describes a rotation-only CT scanner with beam deflections; the deflection and the rotation being so related as to permit the derivation of absorption data in groups focussed on respective "pivot points" outside the detector locus. Data derived from different detectors, but focussed on the same pivot point, relate to groups of paths, some of which overlap, and the overlap is used ...

An X-ray apparatus, comprising a weight compensation device which is suspended from the ceiling and which includes a carriage which is displaceable along the ceiling. A component is displaceable along a patient table is suspended from the carriage by means of a cable. A signal from a transducer is applied to an electric motor which drives the carriage compensate for the relative displacement betwe...

In the cell-separating walls (3) of a multi-cell accumulator block (1), cavities (5) are formed during the injection moulding by injection needles supplied with air, which cavities (5) can be inflated subsequently by the injection of a plastic (6) which can form foam, e.g. polyurethane. The wall-bubbles (7) formed in this way produce a compression pressure which also ensures fixed, permanent posit...

PURPOSE:To improve efficiency of braking by providing an energizing force of an energizing device for energizing a differential piston of an automatic valve provided in a second system in the pressure holding direction less than that for holding brake force generation starting pressure at the wheel cylinder side. CONSTITUTION:A brake controlling valve 7 is provided between a master cylinder 2 and ...

PURPOSE:To improve the flame resistance and thermal shock resistance of a foamed glass article, by covering the surface of the glass with a coating layer composed of flakes of laminar mineral using an inorganic adhesive resistant to heat and water. CONSTITUTION:A coating layer composed of flakes of laminar mineral such as clay mineral, mica, etc. is applied and bonded to the surface of a foamed gl...

An improved READ/WRITE circuit for a memory array of cells arranged in rows and columns, where each cell is coupled to a bit line via the conduction path of a single gating transistor which conducts in the source follower mode for one binary condition. The circuit includes a voltage multiplying circuit having an output at which is selectively produced either a read voltage, or a write voltage of s...

This invention relates to a liquid composition comprising a C3-C8 carboxylic acid, an ion selected from NH4+ and a Group I or Group II metal according to the Periodic Table due to Mendeleef, and water, the ratio of acid to cation is between 2.1 and 4:1 on a chemical equivalent basis.

A power transmission device of a motorcycle comprising a main transmission case formed integrally with an engine crank case and accommodating a main transmission, and a sub-transmission case provided at the rear side of the main mission case. The sub-transmission case accommodates a sub-transmission which is drivingly connected to the main transmission and also to a rear wheel of the motorcycle th...

Steam, for example, is produced from aqueous brine, by a system that employs preferably hot waste fluid, and nozzle means and rotary separator means generally of a known kind per se. The method steps include transferring the waste heat of combustion source (22) to the brine flowing in heater exchanger coil (23), expanding the hot brine through nozzle means (24) to form a jet of steam and liquid dr...

A reaction product of a fatty acid ester and an organic polyisocyanate is included in a foamable reaction mixture containing an organic polyisocyanate to provide a molded product which can be removed from a mold whose surface has not been coated with conventional mold release agents.

Flexible polyurethane foam having reduced tendency to form burning embers and which produces a char when it is ignited and burned is provided by incorporating into the reaction mixture before foaming an aldehyde or an aldehyde generator. In a preferred embodiment, flexible polyurethane foam of increased flame retardance is provided by also incorporating a flame retardant into the reaction mixture ...

A mechanism for raising and lowering a seat, especially designed for handicapped persons, comprises two supporting arms (A', B') which are both at one of their ends coupled to the seat (E), at the front and rear edge thereof, respectively. At their other end, the supporting arms (A', B') cooperate with a fixed point (1', 2') each. At least one of the supporting arms is coupled to a driving member ...

The outdoor chair consists of a very lightweight and strong lattice square of roughly 25 cm with an edge of roughly 3 cm. Three or four legs have toggle-joints and are telescopic on a ratchet principle. The legs fold up very easily inside the 3 cm edging. - The back of the chair is formed of two flat metal strips fitting onto the 3 cm edge with a stop-piece and covered with canvas. When folded up,...

A pair of brake levers each having a brake shoe thereon acting in opposite directions against a brake drum have one end pivotally mounted and the other end of one brake lever is pivotally connected to a pivotally mounted operating lever. A rod is pivotally connected between the other brake lever and the operating lever. The operating lever is moved in the non-braking direction by an actuator and a...
