Patent number: 4418720Abstract: Solenoid operated directional valves are disclosed which have a modular construction wherein electrical connections between component parts are made integral and concurrent with the act of mounting the component parts together. The modular construction means that no separate lead wires are required to be connected between the component parts. The modular construction: reduces the time required to assemble valves in the factory; facilitates installation and maintenance procedures in the field; permits optional features to be selectively incorporated into or removed from valves in a non-destructive waste-free fashion; and essentially eliminates the possibility of improperly connecting electrical circuits within valves.Type: GrantFiled: March 6, 1981Date of Patent: December 6, 1983Assignee: Double A Products CompanyInventors: Curtis H. Day, Ronald L. Loup

Patent number: 4368818Abstract: A stackable thin-walled cup is designed to absorb telescoping loads with less risk of jamming and is for use in beverage dispensing machines with an ingredient held in the cup. As shown in FIG. 2 an ingredient is retained in the base 11 of the cup 1 which has an inward projecting annulus 6 with upper and lower surfaces 8 and 7 arranged to cooperate with surfaces 4 and 5 of an outwardly projecting annulus at the base of a second stacked cup. Surfaces 4 and 7 form a seal to prevent loss of ingredient and the two surfaces are held in contact by a force due to abutment between surfaces, 9 and 10 of respective cups. By suitable difference in linear dimension between surface 7 and abutment 10 and surface 4 and abutment 9 a force is produced by tension derived from the cup walls to hold the surfaces 4 and 7 together. Telescopic shock loads produce compression on the abutments 9 and 10 and momentarily separate surfaces 4 and 7 which re-engage on removal of the load.Type: GrantFiled: April 13, 1981Date of Patent: January 18, 1983Assignee: Mono Containers (U.K.) LimitedInventors: Robert H. Day, Gonzalo D. Vidal-Meza

Patent number: 4256795Abstract: A heat transfer comprising a temporary support and a label carried on the support. The label comprises a layer of a polyurethane resin system which includes a polyurethane obtained by reaction of a diphenyl isocyanate, a free glycol and a polyester either of the formula ##STR1## wherein R is an alkylene radical of 2 to 8 carbon atoms and R.sup.1 is an alkylene radical of 4 to 10 carbon atoms or of the formula ##STR2## wherein R.sup.11 is an alkylene radical of 4 to 8 carbon atoms. The polyurethane resin system further includes a cross-linking agent and a catalyst so that when the label is placed in contact with an article to be marked and subjected to heat and pressure, the resin system is converted to an inert insoluble and wear resistant form and a substantially permanent marking is produced on the article.Type: GrantFiled: May 27, 1977Date of Patent: March 17, 1981Assignee: Polymark CorporationInventors: Ian H. Day, William A. Baldwin, Harold J. Stern

Patent number: 4232688Abstract: A gingival cord container cap is disclosed featuring a cord dispensing gate mechanism formed by cooperating parts of a pivoted dispensing spout and a cap base in which the spout is socketed. Cord threaded out of the container through a hole in the cap base and through the spout may be withdrawn freely when the spout is swung into alignment with the hole in the base (i.e., the gate-open position). As the spout is pivoted out of such alignment (closing the gate) the cord is pinched and held, so that it may be cut off flush with the aperture of the spout, protectively retaining the remainder in the container. Swinging the spout back into aligned position causes a short segment of the pinched cord to be automatically projected out of the tip of the spout where it can be manually grasped for withdrawing additional cord from the container as needed.Type: GrantFiled: September 26, 1978Date of Patent: November 11, 1980Assignee: Pascal Company, Inc.Inventor: Reed H. Day

Patent number: 4231120Abstract: The securement of an endoprosthetic orthopaedic member of plastics material in cancellous bone involves the provision of a relieved configuration on the member, the upstanding elements of such configuration flexing to afford an interference fit upon translation of the member into a substantially complementary, but slightly undersized recess in the bone. The member is suitably of stem or other elongated form with an annular or helical finned configuration as the upstanding elements. Preferably each such fin configuration includes a sequence of longitudinally separated fins individually extending over a minor circumferential portion of the member. The member will commonly be formed as a one-piece projection from a prosthetic bone joint component.Type: GrantFiled: September 18, 1978Date of Patent: November 4, 1980Assignee: National Research Development CorporationInventor: William H. Day

Patent number: 4191438Abstract: A visual display rack includes an extension bar vertically slidable in a hollow standard. A one way clutch mechanism allows the bar to be raised but unless released, locks the bar against downward movement in order to support the load placed upon the bar. The clutch mechanism is released by a button inconspicuously located at the top of the bar. The entire clutch mechanism is carried by the extension bar. The standard is not in any manner altered for cooperation with the mechanism.Type: GrantFiled: June 19, 1978Date of Patent: March 4, 1980Inventor: Robert H. Day

Patent number: 4185661Abstract: A solenoid operated directional valve with detent means for retaining the spool of the valve in either of two selected positions, the detent means being operatively associated with the solenoid pins for holding one or the other of the pins in a selected position and thereby for retaining the spool in a selected position in the absence of any direct connection between the detent means and the spool, the detent means further being located out of the flow-passageways of the valve so as to preclude interference with fluid flow and being constructed and arranged to provide detent disengagement forces of uniform low limits and with no side loads applied on the spool, and to contain no loose parts and to have a near infinite life.Type: GrantFiled: August 17, 1978Date of Patent: January 29, 1980Assignee: Double A ProductsInventors: Arthur W. Gill, Ronald L. Loup, Curtis H. Day

Patent number: 4135505Abstract: This invention concerns variably connectable orthopaedic fracture fixing apparatus of a kind comprising at least one elongate member, at least two universal joint assemblies for coupling said member and associated bone pins, and an adjustment assembly for adjusting the spacing between said joint assemblies when connected with said member. In the present case the joint assemblies are each of ball joint form in which a ball is clamped by a wedge action between two sockets. Also, the adjustment assemblies are not necessarily integrated with a fracture fixing network constructed with the apparatus, but are separable therefrom. In addition, the joint assemblies can receive bone pins in a variety of closely spaced positions to minimize any need to stress the pins.Type: GrantFiled: April 14, 1977Date of Patent: January 23, 1979Assignee: National Research Development CorporationInventor: William H. Day

Patent number: 3964856Abstract: Apparatus and method for thermoforming two or more plastics sheets simultaneously, to form in one operation a double-walled cup, or a composite walled cup, or a plurality of single-walled cups. The sheets are moved and heated simultaneously, the portion not being thermoformed being kept apart, permitting economy of scrap remelting. The thermoformed portions can be kept apart by pressure between the sheets, which can serve to hotform the sheets against respective mould surfaces, or air pressure can bond the sheets together. Existing machines need substantially only an additional clamping plate, heater, and compressed air passing through a radial port in a clamping plate, to incorporate the invention.Type: GrantFiled: June 16, 1975Date of Patent: June 22, 1976Assignee: Illinois Tool Works Inc.Inventor: Robert H.
