Abstract: REUSABLE DUNNAGE DEVICE     Abstract A reusable dunnage device which cushions goods from normal shocks during transit and withstands extreme impacts without damage.  A pair of elongate boards are disposed adjacent an elongate, flexible, inflatable rubber tube on opposite sides thereof and this combination is placed vertically between parcels of goods.  The boards and tube are held together and protected by an elongate canvass sack having a center pocket for receiving the tube and two side pockets for receiving the respective boards.  The width of the tube when filled with air is greater than the width of the boards so that the device may be placed against the parcels of goods with the center, tubular portion of the sack abutting the parcels while the outer, board portions of the sack are disposed a distance away from the parcels.       When the parcels move toward one another under normal shocks the tube will flex, thereby absorbing the shocks; but when an extreme impact is received the parcels will be stopped by the boards thereby preventing complete flattening of the tube and accompanying rupture.  The device is particularly adapted to be placed between parcels of panel products shipped in railroad cars and thereafter pressurized with air.  Upon arrival of the goods at their destination the tube is deflated and reused or the boards are removed and the sack and tube are returned to a collection point.

Abstract: ABSTRACT:            The so-termed xonix chambers can be used only with comparatively low electrode voltages in the so-termed Townsend-plateau region of the discharge where no charge carrier multiplication occurs. The sensitivity, however, is then comparatively low. The sensitivity can be increased by increasing the electrode voltages, but this gives rise to high electrode voltages for a reasonable charge carrier multiplication. When a gas is added whose ionisation energy is smaller than the energy of the lowest metastable levels of the rare gas present in the chamber, the charge carrier multiplication, and hence the sensitivity, can be improved without the electrode voltage being substantially increased.          For example, when 0.2% by volume trimethylamine is added, an electrode voltage of 13 kV already suffices.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for producing inorganic crystalline base exchange materials having high total exchange capacities and specific initial exchange rates which yield well-defined residual concentrations for the elements of Group II of the Periodic Table.  The method of the invention includes the concept of controlling the rate of the addition of the reactants and other reaction variables to prevent gel structure formation and to provide a precipitate of discrete particles with a preoriented array of the elements that is predisposed to the final crystalline structure.  Recycle of the mother liquor to provide a totally closed system is further disclosed.  By preventing the formation of the gel structure it is possible to eliminate cumbersome and costly processing steps and equip-ment.  By varying the precipitation and crystallation conditions, it is possible to control the ultimate crystal size.  Recycle allows recovery of the chemical values of the mother liquor and reduces manufacturing cost.  Throughput is also significantly increased.  Specific and significant process steps include:  make-up of the reactants, purification purge of the reactants, precipitation, crystallization, decanting and quench, solids separation and recycle of the mother liquor to provide the closed system.  Recycling includes concentration and desalination.  The method of the invention further includes particularly unique processing steps comprising solids separation and countercurrent washing.

Abstract: Abstract of the Disclosure A delayed latch strobe generator for a display on a monitor used to service digital logic systems wherein time-based or event-based latch strobes are generated.  A device on the monitor can be pre-set by a user to select the interval between the system latch strobe and the delayed latch strobe.  When the normal latch strobe occurs, a binary counter is enabled.  This counter is then incremented by system clock pulses.  An exclusive-NOR comparator continually compares the counter contents with the setting of the user-controlled device.  A match, which indicates the interval has elapsed, results in the generation of a delayed latch strobe which is applied to the display.

Abstract: ABSTRACT OF DISCLOSURE     The present invention relates to an apparatus in the form of a holder for hard mounting an optical member to a rigid base in order to maintain the re-lative spatial alignment of the assembly in the pre-sence of differential thermal expansion of the elements of the assembly.   The apparatus or holder comprises a tubular member terminating at one end with a base for attachment to the mounting structure for the assembly, while it its opposite end the holder has flange portions for engaging the optical member.          The longitudinally extending portion of the holder comprises thin wall,spring finger members which are disposed to establish bilateral symmetry in a plane perpendicular to the longitudinal axis of the holder, which bilateral symmetry assures the maintenance of the spatial alignment of the members of the assembly.          The optical member is hard mounted to the flange of the assembly by a suitable rigid epoxy.  The hard mounting of the optical apparatus assures that there is no relative movement between the spring fingers and the optical member.  The spring fingers, however, allow for differential expansion between the optical element and the base of the mount.

Abstract: ABSTRACT:             An automatic optical focusing system suitable for apparatus for reading optically an information track on a record with the aid of a read beam (typically a video disc player) serves to keep the read spot automatically focused at the plane in which the information lies during playing of a record. The system comprises an optical focusing device, an oscillating optical element which cooperates with the radiation beam and which can effect high-frequency oscillations so as to cause high frequency oscillations of small amplitude about the coarse position of the focusing plane, an electromagnetic drive system for the high frequency drive of the oscillating optical element, a radiation-sensitive detector which responds to the radiation beam after it has been modulated by the information track, and a control circuit for producing a control signal which depends on the output signal of the detector, which control signal is applied to the control coil of the optical focusing device. The oscillating optical element is constituted by an oscillating mirror which reflects the radiation beam, and said mirror performs high-frequency bending oscillations of which at least a component has the direction of the reflected part of the radiation beam. Preferably, the oscillating mirror is round and performs high frequency bending oscillations between a convex and a concave shape.

Abstract: Abstract of the Disclosure A solid electrolyte tube closed at one end and two porous electrode layers respectively coated on the outer and inner surfaces of the electrolyte tube constitute a known oxygen concentration cell.  A tubular metal shell encloses the electrolyte tube partly such that a closed end portion of the tube protrudes from the shell and that the outer electrode coating is locally in contact with the inside of the shell.  To protect the open end of the electrolyte tube against splashing of water during use without interrupting the admission of atmospheric air as a reference gas into the inside of the electrolyte tube, a tubular cap member of a metal is coaxially fixed to and electrically connected at its one end to the shell at one end portion surrounding the open end of the electrolyte tube, and a cross-sectionally circular plug of an insulating material is coaxially and tightly received in and fixed to the cap member to occupy an end portion, contiguous to the free end, of the interior of the cap member.  This plug has two axial bores which respectively allow two cable wires of the sensor to tightly pass therethrough and an air-admitting passage formed therein independently of these two bores in such an arrangement and cross-sectional area that unpressurized water does not pass therethrough from the atmosphere to the unoccupied portion of the interior of the cap member.

Abstract: CURRENT CONTROLLED OSCILLATOR          Abstract of the Disclosure A transistor oscillator has first and second tran-sistors interconnected with a resonance circuit and a current source connected to supply current to each transistor emitter.  Short circuit conductors connect the base of the first transistor to the collector of the second transistor and the base of the second transistor to the collector of the first transistor.  A current return path to the current supply causes oscillatory signals to be generated.  Regulation of the current flow from the source through the transistors provides current at levels exceeding the saturation of the transistors to vary the frequency range of the oscillator signal.  The frequency of oscillation across the resonance circuit is detected.          The arrangement permits generation of a variable frequency output by regulation of the current input of the tran-sistors in a simple and inexpensive manner utilising relatively few components.
