Abstract: ABSTRACT OF THE DISCLOSURE Apparatus is provided for applying a bead of gasket-forming material to a mateable surface of a workpiece.  The ap-paratus includes a source of gasket-forming material and a screen having a predetermined pattern conforming to the desired bead of the gasket-forming material.  A spreader applies the gasket-form-ing material to one side of the screen and the gasket pattern is then formed on an adjacent transfer surface of a transfer pad on the opposite side of the screen.  Means are provided for moving the pad with the pattern on the transfer surface and engaging it with the mateable surface of a workpiece mounted on a support spaced from the screen, thereby forming a bead of gasket-forming material on the mateable surface.  The transfer surface is moved through an arc of 180° when moving from the screen to the work-piece surface.  If desired, two of the transfer surfaces can be positioned on opposite sides of the transfer pad.

Abstract: A feedback system for controlling the speed of a fluid motor includes an optical-signal transmitter, an optical-signal receiver, and an optically sensitive marker on the motor output shaft. The marker selectively couples the optical-signal transmitter to the optical-signal receiver to provide an optical-signal indicative of motor speed. This selectively coupled optical output signal is fed to a converter which converts the signal to a fluid signal. A processor is coupled to the converter for processing the fluid signal to provide a processed fluid signal which is coupled to the input of the fluid motor to control it.

Abstract: ABSTRACT     The subject invention is an oil supply system for use in such devices as chain saws for supplying lubricating oil to contact surfaces.  The oil tank is pressurized by communication with the engine crankcase of the device through a pressurizing passage having a one-way flow valve.  A regulating valve is also situated in the pressurizing passage, adjustment of which regulating valve compensates for variation in working conditions.          Oil flow after stoppage of the engine may also be prevented.  Prior such oil supply systems featured a fixed size breather hole in the oil tank, and such systems had continuing oil flow after engine stoppage and no means of compensating for variations in working conditions.  Various embodiments of the oil supply system of the subject invention are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         A switch which can be used to actuate brake lights of a vehicle during air brake application.  The switch is comprised of a flat-leaf type armature and an air-actuated plunger which is operative to move the flat-leaf type armature to a position where contacts on the armature touch fixed contacts to provide electrical circuit continuity between the fixed contacts.  The switch is comprised of a housing, a resilient armature in the housing, a first support for slidably supporting a first end portion of the armature, at least one finger that projects out from the first end portion of the armature toward the second end portion thereof, the outer end portion of the finger being unsupported and having a first contact thereon.  A second contact in the housing is in spaced relationship to the first contact.  Air pressure actuated apparatus applies force against the armature between the first and second supports to flex the armature and thereby cause the contacts to close.  The structure provides a fast make and break and wiping action of the contacts, mitigating the problems of welding of the contacts, contact build-up, etc.

Abstract: ABSTRACT           A no-lash telescoping steering shaft (10) comprises first and second telescopically arranged parts (12, 18) which are configured to transmit torque therebetween.  The first and second parts carry an axially and radially movable locking piece (68) engaging the first and second parts at points which are axially spaced apart.  The locking piece is coupled for axial movement with the inner of the two parts and frictionally engages the outer part to prevent relative axial move-ment thereof.  Because the locking piece engages the first and second parts at axially spaced points, it creates a moment therebetween.  The moment opposes side-to-side relative movement of the two parts in a first axial plane.  The moment also urges cooperating surfaces (86, 88) of the two parts into engagement.  The cooperating surfaces resist side-to-side relative movement of the two parts in a second axial plane which is substantially perpendicular to the first plane and also eliminate rotational lash from the steering shaft.

Abstract: Abstract of the Disclosure A gas sensing apparatus is adapted to detect the presence of a gas of interest in air in very small quantities and to provide a rapid alarm or other indication in response to the presence of such gas.  The apparatus incorporates a gas sensing composition which changes its electrical resistance more dramatically than previously possible in response to the presence of the gas and electronic circuitry designed to sense and evaluate the patterns of resistance change during the first approximately 30 seconds after exposure to gas and to accurately estimate gas concentration based on such initial resistance variations.  The system also looks at overall change in sensor resistance to detect gradually increasing gas levels.  A pre-ferred method of manufacturing the sensor and a sensor con-figuration particularly suited to the early detection of gas levels are disclosed.

Abstract: ABSTRACT     Blocks of data, each representing ninety-six lines of a digital television signal are subjected to horizontal shuffling 3, 4 within each line and then to vertical shuffling 7, 8 within each block. The effect of the vertical shuffling is to displace sample words to different lines so that in theevent of errors occurring during recording and reproduction in a video tape recorder 11, valid sample words are available adjacent to any error sample word for the purpose of error concealment. The vertical shuffling does not interfere with vertical parity generation 10 or with the correction of errors 13,18 after reproduction using the vertical parity words.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved method of manufacturing a heater nozzle for an injection molding system.          The heater nozzle has a helical heating element which is cast into an outer portion around an inner liner through which the melt flows.  The outer portion is formed of a conductive material such as a beryllium copper alloy and the inner liner is formed of a durable corrosion resistant material such as stainless steel to provide an excellent combination of these characteristics.  The heater nozzle is made by positioning the heating element around a preheated solid threaded liner in a mold and pressure casting the beryllium copper outer portion around them.  The elongated liner is very accurately located in the mold by having the lower end received in a seat in the mold and the upper end received in an aperture through the plunger as it closes.  In another embodiment, the inner liner is provided with a Y-shaped joint by attaching an arm portion to it by brazing them in a vacuum furnace prior to the pressure casting step.  After pressure casting, the liner is then drilled to form the melt passage through it and the heater nozzle is machined to remove the projecting ends of the liner and to finish the outside according to predetermined dimensions.  This provides a very economical method of making heater nozzles with the necessary combination of characteristics to withstand the operating conditions of a large range of applications.
