Abstract: VALVE MEMBER FOR PILOT OPERATED VALVES               Abstract of the Disclosure A valve member including a flexible diaphragm (16') movable into and out of engagement with a valve seat (14') to close and open the valve, respectively.  A rigid support plate (19') rests against the face of the diaphragm opposite the face which engages the valve seat.  A stem (36) projects from the plate, through a hole (35) in the diaphragm and into the orifice (13') surrounded by the valve seat.  The diaphragm and plate are not rigidly secured together, so that the entire diaphragm is free to flex with respect to the support plate.  A pilot passageway (26') may extend completely through the plate and stem.  The stem is long enough such that the lower end of the pilot passaseway is below the plane of the valve seat even when the valve is open   An abutment, such as an outwardly projecting bead (37), on the lower end of the stem prevents accidental separation of the plate and diaphragm before they are assembled with a valve.

Abstract: SHEET FEEDER FOR A COLLATOR   Abstract In a collator which assembles sheets, the sheets are pushed upwardly by individual sheet pusher arms from each of a group of generally vertically oriented sheet storage bins to a generally horizontal conveyor system which then pulls up and conveys the sheets from the bins to a discharge station.   The sheets from the respective bins are fed into the conveyor system at the same time by the sheet pusher arms which are reciprocally driven by a cam actuated bar.  The sheet pusher arms are magnet-ically latched against a member at the top of their upward feeding stroke.  This latching is accomplished by an extension of the rear wall of the bin which is angled so as to force the sheet pusher arm back against the magnetic latch member.  The sheet pusher arms remain in this latched position out of engagement with the pack of sheets in the sheet storage bins during their downward stroke.  At the bottom of their stroke, a pin carried on the sheet pusher arms engages a cam and mechanicaly breaks the magnetic latch and allows the sheet pusher arm to again engage the sheets in the bin for the next upward stroke.  The individual unlatching cams are mounted on a push-pull rod to enable the cams to be retracted from an operating position thereby permitting the sheet pusher arms to remain latched and effectively disabling the sheet feed in individual bins.

Abstract: ABSTRACT OF THE DISCLOSURE A ventilator implemented completely with fluidic devices provides independent control of inhalation time, exhalation time and breathing gas flow rate.  The basic fluidic system comprises a low frequency oscillator which in the form of a flip flop is controlled in its two stable states by means of independently controlled time delay relays. The output of the flip flop is amplified by a digital amplifier and operates an on-off valve which is used to direct breathing gas from the source to the patient. Independent control of the flow rate of the breathing gas is by means of a needle valve.  With this basic fluidic system, there are seven other features of the apparatus.  One is a maximum pressure control which on inhalation is responsive to the patient's breathing air pressure.  The second feature is a sensitivity control, which during exhalation is responsive to the patient inspiratory effort.  The third feature is a positive end exhalation pressure control.  The fourth feature is an intermittent mandatory ventilation control which permits breathing rates as low as one breath per minute.  The fifth feature is a manual control which allows the termination of the exhalation phase and initiation of the inhalation phase manually.  The sixth feature is a sensor which is responsive to the breathing gas pressure at the patient.  If the apparatus becomes detached from the patient, pressure cycling is modified and an alarm system sensitive to this pressure is activated.  The seventh feature is a safety valve which allows the patient to breathe atmospheric air when the supply pressure of the source gas fails.

Granted: 1980-12-23
Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold.  The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configu-rations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes.          The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space.  Solar energy collected on the absorber surface of the inner glass tube wall is trans-mitted to the U-tube and liquid therein.  The U-tube within the collectors is blackened and non-reflecting.  Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer.  The heat transfer liquid is entirely within a closed circuit, which avoids leaks, re-duces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.    The manifold and tubes are fastened to a support structure of novel construction enabling fabrication as a module and mounting on a solar exposure of a structure such as a roof, wall or frame.  Several modules are interconnectable to desired capa-city for a particular solar powered heating or cooling system.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a coupling comprising two connectable and disconnectable coupling parts wherein the first coupling part cradles a sealing device which is longitudinally displaceable and wherein the second coupling part is arranged to achieve the displacement of the sealing device during the connection of the coupling parts.  The sealing device comprises a sealing element and a supporting or holding part.  The sealing device can, depending on the displacement, take either an initial position or a sealing position between the coupling parts.  Coupling sealing devices presently known in the art have certain disadvantages such as short life, inability to withstand high pressures, comparatively strong externally applied connecting force required and, a tendency to seize up.  The present invention seeks to overcome these problems by providing a sealing device containing a separate spring device which actuates the sealing device towards its initial position.  The first coupling part has at least one sealing surface which is interactable with the sealing element in the sealing position.  The coupling parts are also arranged to make a space for the sealing element in the sealing position which is separated from the flow of the media coupled by the coupling.  In a second embodiment the sealing element is designed with an overhanging section directed past the supporting or holding part towards the centre of the coupling parts.  The coupling is arranged to allow the mentioned part to come in close contact against a seal-ing surface on the second coupling part without considerable squeezing and springing by the elasticity of the material of the sealing element.

Abstract: A SCANNING HEAD FOR AN OPTICAL DISC SYSTEM            Abstract of the Disclosure In a scanning head for an optical disc system, a light beam from a laser is transmitted through a monomode optical fiber and then focussed on a record carrying surface of an optical disc by a converging lens.  The end of the fiber can be reoriented within orthogonal planes perpendicular to the plane of the record carrying surface by transducers so as to correct for tracking and timing errors. The laser diode can function both as an emitter and, in an external cavity mode, as a detector of light reflected from the disc.  Drive to the transducers is dependent on tracking and speed error signals generated from the detected light. For tracking and speed error compensation, only lens fiber end, and, optionally, a collimating lens, which are of negligible weight, need be moved rather than the entire scanning head.  This provides a simple structure having a high frequency response and low power consumption.      -i-
