Patent number: 3964807Abstract: A low friction bushing is made by winding a continuous strand of bondable low friction thread impregnated with a bonding resin into the shape of a hollow cylinder having an axial length greater than the finished bushing. The cylinder is inserted into an annular cavity and with heat and pressure is axially compressed therewithin to radially expand it and compact the thread turns and fuse the resin into a solidified matrix with the thread and resin matrix completely filling the cavity and thereafter the solidified bushing is removed from the cavity. One of the cylindrical walls of the cavity is finished with a surface of bearing quality such that the surface of the bushing pressed thereagainst will be of a complementary quality.Type: GrantFiled: May 5, 1975Date of Patent: June 22, 1976Inventor: Charles S. White

Patent number: 3960492Abstract: A method for determining an index of binding proteins in a serum sample comprising the steps of: 1. Forming a mixture of a) the serum sample, having ligand binding sites, b) a quantity (usually a trace amount) of radioactive ligand and c) an amount of non-radioactive ligand such that the total amount of ligand (radioactive and non-radioactive) is in excess of the ligand binding sites available in the serum sample; 2. Contacting the mixture with a quantity of a binder having a preferential affinity for the ligand; and 3. Thereafter determining the distribution of the radioactive ligand such as by measuring the radioactivity of the binder.The method is particularly applicable for determining thyroxine binding protein content in serum.The method is also applicable to determine an index of serum free thyroxine as determined by the ratio of the concentration of thyroxine to the concentration of thyroxine binding proteins.Type: GrantFiled: May 31, 1974Date of Patent: June 1, 1976Assignee: Nuclear Diagnostics, Inc.Inventor: Walter DiGiulio

Patent number: 3947611Abstract: In the preparation of low friction thread for use in the manufacture of bearings the thread is first rendered bondable, is then coated in a bath of bonding resin, is led vertically out of the bath and the resin is cured to the B-stage, and the B-stage thread is wound into spools for subsequent use.Type: GrantFiled: October 29, 1974Date of Patent: March 30, 1976Inventor: Charles S. White

Patent number: 3945410Abstract: Catalytic converter emptying and filling device attachable to the housing of a catalytic converter containing means therein defining a bed for storing catalytic pellets and further having a port therein for emptying the pellets from the bed and housing. The device includes a rigid conduit connectable to the port for passing the pellets to a receptacle or cannister rigidly attached to the conduit for receiving the pellets from the converter and further including a vibrating instrumentality rigidly attached to the device for imparting vibrational turbulence not only to the rigid assembly making up the device but also to the converter housing and the pellets therein to cause the pellets to pass rapidly from the converter through the conduit to the receptacle or in the opposite direction.Type: GrantFiled: April 1, 1974Date of Patent: March 23, 1976Assignee: Kent-Moore CorporationInventor: William G. Clogg

Patent number: 3942419Abstract: An air stream projecting device especially suitable for cooling, heating and ventilating large enclosures by providing both horizontal and vertical control of air streams. The device is usually mounted on the side or end of an air duct and serves as an outlet for the air contained in the duct under pressure. The device includes a rectangular frame in the opening in which a hollow barrel-shaped member is journaled for limited angular movement. One side of the barrel member is opened to the duct to receive air therefrom and the opposite side is opened to discharge air therefrom into the atmosphere of the enclosure. A wall surrounds the discharge opening of the barrel member and projects therefrom beyond the rectangular frame. Carried within the walled opening of the barrel member are a plurality of vanes for directing the discharging air. These vanes are preferably individually pivotally adjustable but may be connected together for joint pivotal movement.Type: GrantFiled: February 21, 1974Date of Patent: March 9, 1976Inventor: Donald Bramston Beach

Patent number: 3941389Abstract: A plurality of discs of progressively different radii are rotated about an upright post by a spinner member having a one-way driving connection with the discs. The discs are free to overrun the spinner member when the latter is slowed and stopped. The discs are also bodily movable as a group axially up and down the post; in their upper position the discs are brought into driving engagement with the spinner member and in their lower position the discs are freed from the spinner member but their rotation is snubbed and eventually halted by stop means. A control member is provided for bodily raising and lowering the discs as a group to enable the discs to be either rotated by the spinner member while in elevated position or braked to a stop while in lowered position. The discs carry different indicia on their exposed peripheral margins and designed to represent different games.Type: GrantFiled: May 30, 1975Date of Patent: March 2, 1976Inventor: Charles W. Guimond

Patent number: 3941172Abstract: Catalytic converter emptying and filling device attachable to the housing of a catalytic converter containing a bed for storing catalytic pellets. In such a converter the housing is formed of inner and outer walls separated slightly from one another to form a space therebetween which is filled with heat insulating material. The inner and outer walls of the housing each have a port registering with the other port for emptying and filling the bed of the converter. The changer device includes a rigid conduit or pipe connectible to the port for passing the pellets to a receptacle or canister rigidly attached to the pipe for receiving the pellets from the converter and further including a vibrating instrumentality rigidly attached to the device for imparting vibrational turbulence to the rigid assembly making up the device.Type: GrantFiled: January 15, 1975Date of Patent: March 2, 1976Assignee: Kent-Moore CorporationInventor: David L. De Martelaere

Patent number: 3933645Abstract: A deep fat fryer trap receivable in the fryer well has imperforate trap portions extending along opposite margins of the bottom wall and an oil straining portion along a narrow medial portion of the bottom wall. The side walls have upper marginal edges closely fitting the well walls. Oil straining portions are also disposed in the side walls spaced upwardly from the bottom.Type: GrantFiled: July 8, 1974Date of Patent: January 20, 1976Inventor: John D. Keramidas
