  • Patent number: 4262490
    Abstract: A selectively mountable cold control device of the type utilized by servicemen for effectuating temporary repairs wherein the device employs alternative mounting means. In the first instance, where the cold control service is to be of a temporary nature, a pair of suction cup mounting members are utilized so as to retain the cold control device in operative relationship with the appliance with which it is used. Alternatively, where the replacement is to be of a permanent or quasipermanent nature, a singular grappling hook mounting member is utilized instead of the suction cup members. The housing of the cold control device is so configured so as to allow selection of either mode of mounting the cold control device with refrigerators, coolers and similar such appliances.

  • Patent number: 3988709
    Abstract: A thermistor sandwich assembly connectable for controlling motor starting windings is enclosed in a relatively thin and conforming case. The sandwich assembly includes a contact plate abutting the case lower wall with plate integral spring fingers against a face of a wafer-like thermistor, another contact plate overlying and having downward projections against the other thermistor face as well as abutting the upper case wall. A plurality of holes in the lower case wall and a bus bar slot through the upper case wall permit air circulation through the case and between the contact plates and thermistor faces for cooling the thermistor, the relay being otherwise free of cooling plates. A bus bar is rigidly connected extending partially through the case bus bar slot in electrical connection with the thermistor sandwich assembly normally transmitting electrical energy to a contact plate but selectively severable or removable to permit addition of capacitance in the electrical circuit.

  • Patent number: 3973584
    Abstract: Upper and lower blocks with registering grooves are assembled about a pipeline with an upper block piercing needle moved downwardly piercing the pipeline. The piercing needle is then moved upwardly providing communication through the pipeline pierced hole and into a transfer passageway of the upper block. A resilient O-ring is positioned within an annular chamber spaced outwardly of a lower portion of the piercing needle compressed upwardly against the upper block and downwardly against the pipeline to seal the upper block groove from the pipeline pierced hole. The lower block groove is formed semi-circular in transverse cross section and the upper block groove is formed semi-elliptical in transverse cross section with the pipeline being deformed totally conforming to the block grooves when the blocks are brought into assembled abutment.
