Abstract: ABSTRACT OF THE DISCLOSURE       A means for producing electricity from an electrochemical reaction as well as for storing and recovering electrical energy, which utilise electrochemical reactions.  The basic galvanic cell comprises a first solid non-porous body capable of storing large quantities of an ionisable compound (this is the case with a metal hydride and hydrogen) the ionised, com-pound (H+ ions) migrating through a thin-film solid electrolyte (alumina)  towards a second body (oxygen or atmospheric air) where the electrochemical reaction takes place (and the water produced is easily eliminated).  The internal resistance of the cell is low because the electrolyte is in thin-film form. The technology of thin-film deposition is possible because the first body is a non-porous solid.

Abstract: RCA 71,468 IMPROVED AVERAGE BEAM CURRENT LIMITER              Abstract of the Invention An average beam current limiter for a kinescope responsive to video signals coupled to the kinescope via a signal transmission channel comprises a source of control signals representative of average current drawn by the kinescope.  When average beam current exceeds a predetermined threshold level by an amount within a first range of beam current, a corresponding control signal is coupled to the signal transmission channel to vary the D.C. content of the video signal in a direction to limit beam current above the threshold level within the first range.  When beam current exceeds the threshold level by a relatively greater amount within a second range of current, a corresponding control signal serves to vary the peak amplitude of the video signal to limit beam current within the second range.

Abstract: ABSTRACT           The present invention provides a rotary piston machine which includes a casing having interchangeable fluid inlet and outlet ports, an internally toothed stator member and an ec-centrically disposed externally toothed rotor member which is in meshing engagement with the stator member.  The rotor member has rotational movement about its own axis and orbital movement about the axis of the stator member, with the teeth of the members inter-meshing in sealing engagement to form a group of expanding cells on one side of a rotating line of eccentricity and a group of con-tracting cells on the other side of that line during relative move-ment between the members.  A drive shaft in the casing is connected to the rotor member and a valve plate is attached to one side of the rotor member so as to have a sliding and abutting engagement with the stator member in a transversely extending plane.  The plate includes first and second sets of circumferentially and al-ternately arranged porting means for sequential fluid engagement with the cells.  The first set of porting means is in constant fluid communication with a first one of the ports and a first group of the cells.  The second set of porting means is in constant fluid communication with the second one of the ports and a second group of the cells.  A generally annular shaped recess is formed between the periphery of the valve plate and the interior of the casing and has fluid communication with the first one of the ports and the first set of porting means.  The first set of porting means has flow controlling valving edges in the aforementioned plane, which cyclically intersect the cells and are formed by the periphery of the valve plate.

Abstract: CLAMPING DEVICE FOR CLAMPING PLATE-LIKE MEMBERS          Abstract of the Disclosure The disclosure relates to a clamping device capable of readily combining or disassembling plate-like members made of cardboard or similar material, such as corrugated boards, etc. for packing cases and the like.  The clamping device is made of plastics material, for example, poly-propylene or the like, and includes a flat base portion, a pair of pivotal members hinged by means of thin sections of the material to the base portion, and inwardly curved piercing members extending outwardly from the respective pivotal members.  The piercing members may be forced into the plate-like members to grip them in an efficient manner.  The pivotal members are hinged on the base portion in such a manner that they can be moved by hand from a released position extending from the base portion to a clamping position generally parallel to the base portion and vice-versa, and they are sufficiently rigid and sharp at their tips that they can be forced into the plate-like members.  The pivotal members have portions grippable by hand so that they can easily be returned to the released position from the clamping position when desired.  Thus, the clamping device can be used quickly and effectively for sealing a packing carton or the like and can be released quickly and easily, and reused if desired.

Abstract: CONTROLLER FOR ROTARY COLLATOR            ABSTRACT        A rotary collator having a rotatable drum with a plurality of radially extending partitions or bins in which sheets to be collated are held by a sheet clamp mounted in each bin.  The sheet clamp for each bin has a solenoid-based activating device which releases the sheet clamp during the sheet ejecting portion of the collating cycle according to a program implemented by a con-troller.  The controller is comprised of a programming disc into which selector pins corresponding to specified bins are inserted. The programming disc moves relative to an electromechanical mech-anism which enables an electrical switch to complete an electrical circuit to activate the solenoid.  The spacing of the selector pins is such that consecutive empty bins require the electrical switch to be maintained in a disabled position, while consecutive loaded bins result in maintaining the electrical switch in an enabled position, thereby eliminating bouncing of the switch and the associated solenoid.  The sheet clamp is released a short time before the rotatable drum brings the associated bin into a sheet ejecting position.  A toggle structure and a relatively high com-pression spring are used to hold the sheets in the bin when in clamping position.  The sheet clamp of any empty bin is programmed not to release, thereby greatly reducing noise and extending the life of the mechanism.

Abstract: ABSTRACT   A continuous beam from a laser is divided into two intermittent beams by a reflecting disc with peripheral holes, rotating about an axis skew to the continuous beam.  At least one of the intermittent beams is transmitted to a marking head having a lens which focuses the beam onto the surface of a roll.  The roll is rotated and the marking head is moved along the roll, in synchronism with the rotation of the disc, so that a regular hexagonal lattice of microcavities is cut by the focused intermittent beam.  The second intermittent beam maybe used to cut microcavities in the roll or in a second roll or for other purposes.

Abstract: (Case No. 7062) ABSTRACT OF THE DISCLOSURE    An LC series resonant regulator is connected across the output of the inverter circuit of a static converter apparatus to vary the output voltage level as the inverter operating frequency varies from a preselected frequency at which the regulator circuit is tuned.  The load is coupled across the capacitor element of the regulator and a level detector coupled across the load input.  This detector registers vari-ations of the input to the load from a predetermined desired level of load voltage and supplies a feedback signal, indica-tive of any detected variations, to the control circuit for the inverter circuit element.  This control circuit is respon-sive to a feedback signal to vary the operating frequency of the static inverter so that the regulator varies the output voltage applied to the load to restore the desired voltage level.
