  • Patent number: 4159138
    Abstract: A snap-acting latch mechanism for sliding doors is disclosed in which a latch bar is rotatably mounted and extends from a latch assembly for insertion into a keeper assembly. The keeper assembly is formed for cooperative engagement of a head portion of the latch bar to retain the same against withdrawal and yet the latch bar can be rotated to a position enabling withdrawal from the keeper assembly. In the improved mechanism of the present invention the keeper assembly includes a pair of resilient band means mounted in side-by-side, spaced apart relation so as to snap into engagement behind the head of the latch bar and yet enable withdrawal of the latch bar upon rotation of the head by 90.degree..

  • Patent number: 4146951
    Abstract: A method and apparatus for tensioning concrete reinforcing tendons or the like are disclosed which are particularly well suited for use in the construction of prestressed concrete tanks. The method includes mounting a wedge assembly on the tendon and mounting a wedge assembly housing around the wedge assembly, with the improvement being comprised of the steps of forming a spiral groove of relatively shallow depth in the tendon prior to mounting the wedge assembly thereon, and rotating the housing in a manner similar to a turnbuckle to simultaneously and proportionally induce radial tendon gripping forces in the wedge assembly and substantial axial tension forces in the tendon. The method has the additional advantage of preventing relative slippage between the wedge assembly and tendon even when conventional tendon jacking techniques are employed to tension the tendon.

  • Patent number: 4143676
    Abstract: The invention concerns hydraulic control valves suitable for e.g. motor vehicle steering gear. A variety of control port configurations are formed between cooperating ribs and bores on the control piston -- which may be rotary or axially displaceable -- and on the control sleeve. In each case the resulting control ports are defined by circular arcs having a common chord arranged at right angles to the direction of the control displacement for example at right angles to the direction of the control displacement for example at right angles to the direction of rotation of a steering spindle.

  • Patent number: 4138924
    Abstract: A method for making electrical circuits on a non-conductive plate is disclosed. The invention provides for duplication of a circuit pattern on an insulating plate having a continuous deposit of electrically conductive material thereon by a mechanical linkage between a milling device, which removes the conductive deposit, and a scanning device, which is moved in accordance with a master pattern. In preferred embodiment the movement of both devices is confined to one of two or sometimes three co-ordinates for a particular portion of the pattern. The method is swift and efficient, and the invention is equally applicable to small or large-scale manufacture, although it is of especial value where small numbers of circuit boards are to be produced.

  • Patent number: 4138203
    Abstract: A compressor or pump or motor-type structure having a housing with a bank of cylinders and a shaft journalled for rotation therein and fitted with a swash plate, sometimes referred to in the art as a wobble plate or cam or drive, which is connected to pistons mounted for reciprocation in the cylinders and which will effect such reciprocation upon rotation of the shaft. When used as a motor, entry of fluid under pressure into the cylinder heads will effect displacement of the pistons and driving of the shaft. Improved means is provided in the present structure for supporting the swash plate against rotational forces imposed thereon, in the mounting of the swash plate and in the connection between the swash plate and the pistons.

  • Patent number: 4136793
    Abstract: A load stabilizer for use with a forklift truck which includes a frame, top and side clamping mechanisms formed so that they may be clamped down on a load, for example boxes or the like, to hold the same in place while being carried by the forks of the forklift truck. The top and side clamps are gravity and spring biased to an unclamped position and are formed for displacement to a clamped position upon engagement of the top clamping mechanism with the load. The entire stabilizer can, while still mounted to the forklift, be positioned in a stored position for towing. The load stabilizer is hydraulically powered from the forklift truck hydraulic system and may optionally include hydraulic side clamping apparatus movable to a position enabling top clamping of wide loads.

  • Patent number: 4122947
    Abstract: A pre-packaged patient identification kit and method for assuring correlation between a patient, his specimens and his records is disclosed. The kit is preferably formed as a transparent package inside of which a wristband, at least one specimen container and, optionally, a label are disposed. The wristband, specimen container, and label are pre-numbered with identical patient identifying indicia. The kit is used by first visually verifying that all indicia are identical, attaching the wristband to the patient, taking a specimen from the patient and placing it in the specimen container, and placing the label means on the patient's record. After analysis of the specimen, the patient identifying indicia is copied onto a label for a therapeutic agent to be given to the patient; and finally, before administration of the therapeutic agent to the patient, the indicia on the label of the therapeutic agent is checked against the indicia on the patient's wristband and his records.
