  • Patent number: 4284014
    Abstract: A safe rigidly and permanently mounted in an opening in a concrete wall or floor. Two interfitting sleeves co-operating in a pre-oriented, rigid relationship with each other and the surface bordering the opening to preclude unauthorized removal. A container element is assembled to one of the sleeves. To retard "sweating" or the accumulation of moisture in the container and to obviate corrosion development, a rigid plastic, such as polyvinyl chloride, is used for container fabrication. A cover is provided which is releasably secured in close fitting relationship to one of the sleeves, capturing a cover plate therebetween in pre-selected orientation adjacent the safe mouth. The co-operation between the cover, the cover plate and the interfitting sleeves maximizes safe security and precludes extraction from or pushing through the opening in the wall or floor.

  • Patent number: 4235713
    Abstract: The present invention refers to a process for the elimination of accumulated iron in organic phases of fluid-fluid extraction that contain di-2-ethyl-hexyl phosphoric acid, by means of its treatment by direct contact with an acid aqueous solution of chloride ions, which is subsequently subjected to the action of an anionic ion exchanger that extracts the iron and leaves it iron-free for its re-utilization, and the regeneration of the anionic exchanger by means of treating it with water, purifying the iron from the system in the form of a relatively concentrated ferric chloride aqueous solution.

  • Patent number: 4215366
    Abstract: A method and apparatus for encoding and decoding of standard television signals are provided for enabling reception thereof in an intelligible manner only by authorized subscribers. The scrambling of the video signals is effected by inversion of the video signals of some horizontal scan lines on a pseudo-random basis to produce a picture having some video signals inverted and others not inverted which is unpleasant to view and virtually unintelligible. The scrambling of the audio signals is effected by conversion of analog audio signals to coded digital audio signals. A plurality of unique pulse coded control signals consisting of 32-bit binary pulse trains are transmitted separately to identify individual authorized subscribers and to provide information needed to unscramble the scrambled video and audio signals.

  • Patent number: 4213770
    Abstract: A pollutant separator having a cooling coil and a filter includes a scrubber device. The scrubber has a tube with holes in the walls thereof for the passage of fluid to and from a closed collection chamber. A series of spring biased balls within the tube serve as scrubber elements. Extending around part of the outside of the tube is a slidable spring-biased ring valve having a shoulder on which fluid pressure is exerted through a passage extending from inside the tube. The ring valve slides over some of the tube holes causing fluctuations in pressure within the scrubber unit to enhance vibratory, scrubbing motion of the balls contained therein.BACKGROUND OF THE INVENTIONThis is a continuation-in-part of my copending application, Ser. No. 764,707, filed Feb. 1, 1977 now abandoned, which is in turn a continuation of my abandoned application, Ser. No. 566,608, filed Apr. 8, 1975, which was a continuation-in-part of my application Ser. No.

  • Patent number: 4207681
    Abstract: An apparatus for reforming and straightening damaged bodies and frames of vehicles whereby corrective forces are applied to the vehicle through one or more elongated force transmission elements. A force is imposed on the elongated elements respectively by means of a uniquely mounted hydraulic ram which is freely pivotable sideways and limitedly pivotable in a backward direction. Each of the hydraulic rams are attached to a frame situated beneath the vehicle to be straightened whereby the frame further supports a measuring bridge coupled to the vehicle so that the progress of a straightening operation can be readily determined. The measuring bridge includes vertical indicators or gauges which are coupled at datum points on the vehicle so that an operator can readily determine the deformity of the vehicle longitudinally, laterally and vertically with respect to its center line.

  • Patent number: 4195719
    Abstract: The fastening of a diaphragm spring to the casing of a clutch is effected by means of a annular piece that acts elastically on the diaphragm independently of the riveting, offering a high degree of resistance to flexion between rivets, which piece is of a hollow and incomplete toroidal shape in a support zone on the diaphragm, which zone presents an angular extension of more than 180.degree., permitting an elastic deformation or a reduction of its height of assembly without exceeding the elastic limit of the material that originates the elastic force necessary for the perfect operation of the device and at the same time absorbing the dimensional differences due to the necessary and admissible tolerances of manufacture, with the special feature that the interior part of the said piece is provided with a flange for increasing the moment of inertia of the section of the piece, increasing resistance to flexion between two consecutive orifices of the said piece.

  • Patent number: 4151720
    Abstract: A manually operable hydraulic actuator which utilizes a main pump and an auxiliary pump to quickly develop a relatively large useful hydraulic force, for example, in applying compression accessories to stranded conductors such as cables. The main pump develops a relatively high pressure from a low volume of hydraulic fluid to develop the primary hydraulic force. The auxiliary pump develops a relatively low pressure from a high volume of hydraulic fluid to produce rapid advancement of a force-applying piston relative to a work piece. Both the main and auxiliary pumps are operated by the opposed swinging movement of two manually operable handles. One of the handles is selectively movable between a first position for simultaneously actuating both the main and auxiliary pumps and a second position for actuating the main pump only. A pressure relief system is provided to ensure development of the maximum rated pressure of the force-applying piston before retraction thereof can be effected.

  • Patent number: 4089031
    Abstract: A safety protection circuit for controlling the operation of electrically-powered tools including a switching device. In one application, the power tool is a drill which is utilized in drilling a hole through electrically non-conductive material such as a concrete floor and an electrically conductive material such as a grounded metallic conduit having electrical cables therein disposed directly below the floor. The switching device automatically discontinues the drilling operation when the drill bit contacts the metallic conduit after passing through the concrete floor thereby avoiding any damage to the cables within the metallic conduit or causing a safety hazard. Subsequently, the drill can be reactivated to penetrate the metallic conduit. The switching device will again automatically discontinue the operation of the drill after breaking contact with the metallic conduit.

  • Patent number: 4082869
    Abstract: A method and apparatus for use in continuously applying molten coating metal, such as in galvanizing or aluminizing to tubes, rods, wire or other work pieces passing through a metallic bath. The molten metal in a reservoir is discharged onto the tube or rod, the metal flowing around the tube or rod being controlled by a splash tube. The coating metal is progressively agitated and cooled within the splash tube, after which the tubing or rod is accurately centered to exit the splash tube with an even coating of the desired thickness, such coating being in a stable condition. The entire system is enclosed in an inert atmosphere eliminating the formation of "galvanizers' dross", oxides of aluminum, etc.
