Abstract: ABSTRACT OF THE DISCLOSURE        A relatively rotatable coupling apparatus is dis-closed for conveying fluid from a stationary reservoir to a rotatable member. An adjustable throttle valve is operably connected intermediate of the coupling apparatus and the rotatable member for controlling the flow of fluid from the reservoir to the rotatable member. The relatively rotatable coupling apparatus has a first conduit portion connected to the reservoir defining an inlet flow path and a second conduit portion connected to the rotatable member defining a discharge flow path for the fluid. The first and second conduit portions are interconnected in an overlapping radially spaced apart relation by rotatable interconnecting means to define a relative motion gap between the over-lapping portions and to permit rotational movement of the second conduit portion relative to the first conduit por-tion. The throttle valve has a valve seat disposed in the discharge flow path of the second conduit portion and a valve plug disposed intermediate of the valve seat and the rotatable member. A stem connected to the valve plug extends through the first conduit portion and is mechanically linked with an adjustable piston for axially displacing the valve plug relative to the valve seat to provide adjustable throttl-ing of the flow of fluid from the reservoir to the rotatable member.

Abstract: ENERGY ABSORBING SUSPENSION ELEMENT                  Abstract of the Disclosure A suspension element for suspending a load and absorbing energy if the load is increased suddenly above a predetermined minimum includes a normally rigid ring that is permanently deformable under an applied load above said minimum.  Diametrically opposite areas of the ring are connected to a support and a load, but the opposite sides of the ring between those areas are free of the connecting means and subject to being pulled toward each other if the load suspended by the ring suddenly increases beyond the pre-determined minimum and elongates the ring in the direction of the movement of the load.  The energy required to thus deform the ring is absorbed by the ring.

Abstract: Abstract of the Disclosure A dynamic loudspeaker is driven by chopped d.c. from the collector of a transistor.  A free wheeling diode is con-nected in parallel with the speaker circuit to dissipate the inductive energy in the speaker voice coil when the transistor is turned off.  The transistor is controlled by a voltage con-trolled oscillator which, under control of other elements, can be made to produce a wide variety of cyclically varying output signals for producing a wide range of sounds, tones and signals from the loudspeaker.  This permits selection of a tone which differs sufficiently from the ambient noise to assure attracting attention.  By the use of chopped d.c. to drive the speaker, the expense, weight and bulk of an impedance matching transformer is eliminated.  A plurality of individually operable switches are provided for switching circuit elements in and out of circuit to modify wave shapes and alter sound output.  Another group of in-dividually operable switches mixes selected wave shapes to pro-duce various compound waves and produce additional sound vari-ations.  One switch provides pitch control and another provides output volume control.

Abstract: TRIBAND VEHICLE ANTENNA            Abstract of the Disclosure:            An antenna for simultaneous connection to a citizen's band transceiver, an AM receiver and a FM receiver, particularly suitable for use on a vehicle such as an automobile.  The antenna proper is a center-loaded upstanding rod which, in the preferred form, telescopes downwardly to a retracted position where it does not protrude above the ground plane.  The antenna proper is con-nected to a T-connected open stub transmission line and to a FM resonant relatively high impedance signal-carrying transmission line.  The former has inductive reactance in the FM band which off-sets the capacitive reactance of the relatively short effective length of the antenna proper in the FM frequencies.  The signal-carrying transmission line is substantially half wave in length in the FM band so as to reflect impedance at its far end substan-tially equal to the impedance present at the T-connection.  The signal-carrying transmission line is also of length that provides resonant action transforming the relatively low impedance at the T-connection or base of the antenna in the CB band to a higher impedance, such as 50 ohms, at the end of that transmission line.          Finally, the signal-carrying transmission line, because of its relatively high characteristic impedance, has very low capaci-tance and therefore does not tend to load the AM radio.  The end of the signal-carrying transmission line is connected to the input terminal of splitter containing resonant circuits which are in turn connected to two transmission lines, one leading to the CB transceiver and the other leading to the AM/FM radio.

Title: Use of 2-pyrrolidinone derivatives as solvents for  photographic addenda in hydrophilic colloid layers
Inventor: ISHIHARA MASAO
IPC: G03C1/06

Granted: 1981-12-15
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a method for the addition of oil-soluble photographic addenda to a hydrophilic colloidal solution for forming a layer of a light-sensitive silver halide photographic material.  The method comprises dissolving the addenda with a high-boiling organic solvent and thereafter dispersing, into the hydrophilic colloidal solution, the addenda dissolved in the high-boiling organic solvent.  According to the invention the high boiling organic solvent is represented by the following general formula:       wherein R represents an alkyl group or alkenyl having 6 to 22 carbon atoms, R1, R2 and R3 individually represent hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy carbonyl group or an acyloxy group having 1 to 10 carbon atoms.  This enables to obtain good color development of the coupler even if the light-sensitive silver halide photographic material is treated at high temperature and with rapid processing.

Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure depiots in a television cathode ray tube having a getter containing a vaporizable, electrically conductive, gas adsorptive getter material, an improvement comprising an electrically resistive element for arc suppress-sion, internal voltage division, static elimination, RC signal coupling or the like. The resistive element is composed of a high resistivity material compatible with a clean, high-vacuum environment. The element is so widely and deeply cavitated and contorted at and below its nominal surface that the real surface of the element is shadowed and very greatly extended in area relative to the nominal surface of the element. The effect of this is that when the getter is flashed, the coating of conductive getter material deposited on the element is effectively dispersed and fragmented into isolated conductive islands. The result is to render tolerably insignificant the tendency of arc currents to travel over the surface of the element and thereby by-pass the body of the element.
