Abstract: ABSTRACT       In a gear pump, a gear is mounted on a drive shaft of a fuel pump and includes a longitudinal slot dividing one end portion of the shaft into first and second cantilever sections.  Shoulders formed in the slot on the cantilever sections abut a key extending transversly through the slot to protrude from the shaft and the key is received in keyways formed in the gear diametrically of each other and opening into a cylindrical aperture.  The latter is sized to receive the inner end portion of the shaft with a press fit with end walls of the keyways abutting the protruding key to locate the shaft axially within the gear.  The width of the slot separating the cantilever sections of the shaft is slightly greater than the diameter of the key thereby providing clearance between the key and the cantilever sections to allow deflection of the sections during press-fitting of the shaft in the gear.

Abstract: ABSTRACT OF THE DISCLOSURE       A spring and frame assembly, particularly for box springs for beds of extended length, consisting of a plurality of main springs arranged criss-cross fashion on a rectangular supporting frame to form a load supporting deck having a regular array of rectangular spaces, and internal support springs mounted on the frame extending diagonally across associated rectangular spaces and secured to the main springs.  Each internal support spring has a main body portion and depending end portions which resili-ently support the main body portion in spaced relation above the frame.  Selected ones of the internal support springs have longer main body portions than the remaining internal support springs and are arranged adjacent the opposite ends of the box spring assembly to provide the ends of the box spring assembly with additional resistance to downward loads.

Abstract: ABSTRACT OF THE DISCLOSURE         A circuit for an electronic organ for producing rhythmic patterns of notes in accordance with the selection of a chord in the accompaniment manual.   The organ  includes an accompaniment manual and a solo manual, either or both of which may be electronically scanned to develop a multiplexed data stream, and a chord generation circuit controlled by the accompaniment manual for sounding groups of notes in the accompaniment voices in response to the depression of one of the selected group of  keys on the accompaniment manual.          The circuit according to the present invention automatically sounds notes of the solo manual in a rhythmic pattern in response to the depression of one of the group of accompaniment manual keys by developing a logic pulse at the beginning of the top octave scan which is delayed in time to correspond to the time slot of the chord root note and subsequent  notes of the chord.  The amount of delay is controlled by pre-programmed patterns preselected by the musician.

Abstract: ABSTRACT             A fuel injection system for injecting fuel into the combustion chamber of an internal combustion engine includes a multi-way valve, a solenoid for controlling the operation of the valve, a shuttle valve that is moved within a shuttle chamber  in response to the change of state of the solenoid, and an intensifier piston having an upper cylinder movable within actuating chamber and a lower cylinder movable within metering chamber 50.  The position of the shuttle valve, in turn, regulates the admission of pressurized fuel from a high pressure pump into the actuating chamber to drive the intensifier piston in a first direction.          The lower cylinder 66 of the piston 62 is movable within the metering chamber to amplify the pressure of the fuel to a level several times greater than supply pressure prior to introducing same into a fuel injector for discharge into the combustion chamber.  A T-shaped passage in the piston allows the injection phase of the cycle of operation to be terminated sharply by a rapid dissipation of the pressure buildup.  Variable restrictions such as a needle valve, are disposed in a return conduit that allows the fuel in the actuating chamber to be returned to the fuel reservoir and to regulate the volume of fuel that can return to the reservoir per unit of time during the metering phase of operation.

Abstract: ABSTRACT OF THE DISCLOSURE     Rigid synthetic foam is expanded, molded and cured in an endless tunnel formed by opposed spaced horizontal belt conveyors with side dams.  To obtain a smooth finish on the product, a top cover belt and a bottom cover belt are employed to span the rigid slats of the conveyors, respectively.  The top cover belt is stretched tightly and smoothly when the end-less conveyors approach each other at the entrance to the pressure tunnel, by means of a downwardly de-pending continuous wedge shaped member along each side margin of the cover belt that cooperates with an up-wardly opening correspondingly wedge shaped recess in the side dams.  To obtain different thickness products, spacer blocks may be employed between the side dam and the lower conveyor.

Title: Gas sampling devices
Inventor: JONES THOMAS P

Granted: 1983-03-22
Abstract: ABSTRACT A sampling device for automatically obtaining a gas sample from a gas stream at a selected instant of time and which is particularly suitable for use with breath alcohol detection or analysis.  A movable piston or diaphragm is arranged to automatically draw a sample of gas through an inlet passage into a sampling chamber, in response to a change in gas pressure or a change in flow rate in the inlet passage.  When a suspect breaths into a main flow tube the rate of flow will rise and then after a period will fall.  The piston is designed to trigger automatically when the rate starts to fall and in this way the sample is taken at a late stage in the exhalation cycle so that a test can be applied to alveolar breath, from the deep lung.

Abstract: ABSTRACT      A boot or shoe comprises a pre-formed portion and a portion which is moulded in one piece on to the pre-formed portion and which includes the sole unit and those parts of the upper not constituted by the pre-formed portion.   The pre-formed portion comprises side panels extending along each side of the shoe and a sock for under-lying the foot, which sock interconnects the side panels and the side panels and sock may be made in one piece or in separate pieces which are fastened together, as by sewing, before the moulded portion is moulded on to the pre-formed portion.   The moulded portion is made from a plastics material, e.g. polyurethane, and the material does not overlap the inner face of the pre-formed portion but overlaps at least some of the marginal regions of the two side panels.   The sock lies in the top surface of the sole unit.   The two side panels may together extend also round the heel region of the upper and the plastics material may cover the outer face of the panels in the heel region.   The location at which the side panels join the sock, e.g. in a seam is embedded in the sole unit.   The specification describes also the method of manufacture of the boot or shoe.

Title: Method of welding metal pipe sections with explosives

Granted: 1981-12-22
Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided for the explosive welding together of sections of large diameter metal pipe of the kind used in the construction of high volume oil and gas pipelines.   In the method, internal and external band charges of welding explosive are simultaneously detonated adjacent to overlapped telescoped pipe ends.  The welding charges are detonated simultaneously by means of very high detonation velocity initiation explosive charges placed along a leading edge of each welding explosive charge.  The initiating explosive charges are each set off by a single detonator means.          The velocity of detonation of the initiating explosive is selected so that welding charges are simultaneously detonated around the pipes while maintaining the detonation fronts at superimposed locations and at a large angle to the pipe axis.          This avoids unbalanching forces on the pipes and minimizes the collision of circumferential shock waves thus preventing pipe damage and imperfect welds.
