Abstract: ABSTRACT OF THE DISCLOSURE                A heat dissipator for use with a dual in line integrated circuit package.  The subject dissipator is unitary in construction and formed of a resilient material to facilitate rapid mounting and subsequent removal from an IC package. The dissipator includes a pair of opposed top and bottom contact plates interconnected by an intermediate segment.  A radiator plate is provided extending upwardly from the remaining free end of the top contact plate.  The dissipator may be slidably mounted on an IC package, with the bottom contact plate being in contact with the bottom wall of the package and with the top contact plate being in coplanar and contiguous relationship with the top wall of the package.  By this arrangement, heat generated by the IC package during use is conducted by the top and bottom contact plates to the radiator plate for dissipating the heat and reducing the operating temperature of the package.

Abstract: METHOD AND APPARATUS FOR SORTING RIVETS               Abstract of the Disclosure A method of sorting rivets or similarly shaped articles, and apparatus therefor.  Rivets are directed along a track to a notch where they are supported in a shank-down attitude against a rotating gauging wheel having a plurality of gauging holes con-forming generally to the shape of the shank.  The wheel is rotated so the gauging holes move upwardly with respect to the shanks while grooves in the periphery of the wheel guide the shanks toward the holes. Rivets with a uniform shank will settle into the holes so their heads are below the periphery, while rivets with bent, gouged, burred or oversized shanks will not settle fully into the holes.  A rivet kicker timed to the rotation of the wheel ejects rivets not fully settled in the holes.  Fully settled rivets are blown out of the gauging holes into a tube where they are conveyed by air towards a riveting machine.

Abstract: "Switchable analogue signal inverter"            ABSTRACT:         A switchable analogue signal inverter suitable for inverting an input D.C. voltage as required, for example inverting the D.C. voltage from a digital to analogue converter (DAC) and there-by halving the size of the DAC.            Essentially the inverter comprises a capacitor having one side alternately switchable between a reference voltage point and an output terminal and another side alternately switchable between the reference voltage point and an input signal terminal and switching means for selectively reversing the phasing of the switching between the reference voltage and the input signal.            In one embodiment the inverter comprises a double pole reversing switch having inputs connected to a signal input terminal and to a reference voltage point (ground) and a capacitor connected by a change-over switch to first and second outputs ofthe reversing switch and by another change-over switch to a signal output terminal or to the reference voltage point. The reversing switch is operable in response to a polarity change signal to reverse the signal applied to the first and second outputs and thereby determine the polarity of the voltage pumped by the capacitor to the output terminal by clocking the change-over switches. The switches may be implemented by field effect transistors.

Abstract: PROTECTED TELEVISION SIGNAL DISTRIBUTION SYSTEM                  ABSTRACT OF THE DISCLOSURE      A television signal distribution system protects outgoing programs from unauthorized reception; and marks or tags the conveyed signals with a digital word identifying the class of viewers authorized to receive the program ("level of service").          Basic encription is accomplished by effectively suppressing the horizontal and vertical synchronizing information.  Horizontal sync information, and the program-characterizing level of service word which is interleaved in time with prescribed horizontal sync pulses, is distributed via pulse amplitude modulation of the audio carrier.   At subscriber receiving stations, the sound carrier ampli-tude modulation is recovered to permit level of service authori-zation verification; and to reconstitute the video carrier to receivable form by an amplitude modulation which is the inverse of the sync-suppressing modulation of the head end.    In accordance with one feature of the present invention, a further data channel may be employed to vary subscriber service authorizations - as to permit pay-per-view billing.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a tubular casing of fiber reinforced regenerated cellulose comprising a film web which is curved to form a tube.  The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 and an elongation at break of about 30 to 50% in the transverse direction of the web.  The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web.  On its entire surface facing the film strip, the tubular casing has a substantially gas-impermeable and sealable layer, as   s the film strip on the surface which comes into contact with the tubular casing.  The film web is produced from viscose, and is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.

Abstract: Abstract of the Disclosure An electrochemical machining method uses a rotatable electrode disk to cut narrow groove in a workpiece.  An electric current of relatively low density is established between major sides of the electrode disk and side surfaces of the groove to prevent electrolytic erosion of the groove.  In practicing the method, a thin flexible electrode disk is rotated relative to the workpiece.  An electrical potential and a flow electrolyte are established between the rotating electrode disk and the workpiece.  The electrode disk is then moved into close proximity with the workpiece to initiate formation of the groove.  Continued formation of the groove results in the disk entering the groove so that a flow of electrical current is established between side surfaces of the groove and major sides of the rotating electrode disk.  The density of the electrical current between the major sides of the electrode disk and the side surfaces of the groove tends to be minimized by providing openings in the major sides of the electrode disk.  These openings reduce the side area of the electrode disk which is available for current flow.

Abstract: JOSEPHSON CURRENT REGULATOR   ABSTRACT            A Josephson current regulator circuit is described for regulating the gate current to a Josephson load device.  The regulator circuit is located between the source of the gate current and the Josephson load, and is comprised of Josephson devices having a critical current less than the critical current of the Josephson load device. Each of the Josephson regulator devices has at least two states dependent upon the magnitude of the gate current.  A resistance is associated with each of the Josephson regulator devices so that, when the state of the Josephson regulator device is changed, resistance is either introduced or removed from the circuit connecting the source and the Josephson load.  This adjusts the magnitude of the gate current and maintains within a specified range the ratio of the gate current to the critical current of the Josephson load device.
