Abstract: ABSTRACT   In a process for the production of solutions of essentially linear polydihalophosphazenes suitable for the formation of completely substituted, halogen-free polydihalophosphazene derivatives, in which lower molecular weight cyclic dihalophosphazenes represented by the general formula (NPX2)n wherein X represents halogen selected from the group consisting of Cl, Br and I and n represents integers between about 3 and about 7, are thermally polymerized in the presence of a Lewis acid compound catalyst to form a higher molecular weight essentially linear dihalopolyphosphazene of the formula (NPX2)m wherein m represents integers between about 10 and about 50,000 and said linear polydi-halophosphazene exhibits a tendency to form a gelled product when formed in the presence of said Lewis acid compound, which gelled product must be dissolved, prior to being derivatized by a reaction with alkoxy or aryloxy groups in which substantially all of the halogen atoms attached to the P atoms in the phosphazene are removed, the improvement which consists in dissolving said gelled linear polymer product in a hydrocarbon solvent mixture containing up to about 10.0% weight of an oxygen-containing solubilizing diluent selected from the group consisting of aliphatic alcohols, ketones, aldehydes, esters, ethers and polyethers and mixtures thereof prior to derivatizing said polydihalophosphazene in solution.   The process allows the dispersing of gelled polyhalophosphazene to permit its use in the subsequent preparation of derivatives and facilitates clean-out and rinsing of equipment.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved methods and apparatus for making scribed circuit boards.  A conductor is fed to the adhesively activatable surface of a board base which is attached to a movable table.  The conductor is affixed to the adhesive surface by means of an energizeable stylus, the energization of the stylus being modulated proportional to the velocity of the table.  The feed of the conductor and the movement of the base are monitored and compared and a control signal produced if the conductor feed and base movement are not in substantial agreement.  The conductor is positively fed to the board base to eliminate pull on the conductor and substantially reduce the tendency of the conductor to come loose from the board base.  The forming stylus has a vertical groove on at least one side which becomes progressively shallower towards the bottom and which has side walls for laterally  confining the conductor.

Abstract: SOLID-STATE DEVICE FOR LIGHTING FLUORESCENT           TUBES IN EMERGENCY     ABSTRACT OF THE DISCLOSURE   A device for lighting fluorescent lamps in emergency comprises a push-pull oscillator whose transistors act as an on-off switch to obtain a square wave a.c. voltage from a d.c. source.  This a.c. square wave is transformed into various voltages by using a tapped secondary winding on the oscillator transformer.  Two small sections of this secondary winding feed the filaments of the tube and a larger section sandwiched between the above two provides the operating voltage for igniting and maintaining the discharge in the fluorescent tube.  The remaining portion of the secondary winding is cap-acitively connected to the centre of the primary winding which aids starting of the lamp.  The d.c. source is charged by a regulated charger which main-tains the battery fully charged (without overcharging) under normal power supply conditions.  A control device substitutes the use of an electro-magnetic or solid-state relay by keeping the oscillations damped whenever the normal power supply is not interrupted.

Abstract: TITLE: BAG TYPE AIR CLEANING APPARATUS                  Abstract of the Disclosure A bag type air cleaning apparatus is described for collecting particulate sediment from a source of pressurized air.  The apparatus is adapted for connection to the pressurized air source and receives the pressurized air within a cylindrical plenum.  A plurality of upright pervious bags are openly associated with the plenum for receiving the pressurized air.  The air and particulate sediment is forced upwardly into the bags and against the bag interior surfaces where the sediment will collect as the air escapes through the pervious material.  The bags are mounted on upright frames that are collapsible for storage purposes.  A sliding duct is provided in communication with a blower mechanism in order to successively clean the inside surfaces of the bags.  The sliding duct includes a manifold that  comes into contact with successive openings of the bags while being pivoted about within the plenum.  The manifold is connected to the blower mechanism which produces a suction force to reverse the pressure within the successive bags.  The sediment is thereby pulled from the inside walls of the bags and is delivered through the sliding duct to a discharge.  In addition, sediment will settle on the bottom or floor of the plenum. This sediment is gathered and delivered by an auger mechanism to the same discharge.  A biased valve is associated with the auger to close and open alternately in response to outward pressure produced by the sediment being forced outwardly by the auger.  Thus the sediment received from the sliding duct and from the auger is passed through the same discharge and is disposed of by the same blower mechanism.

Title: Digital video effects system employing  a chroma-key tracking technique
Inventor: INABA MASAO
IPC: H04N5/275
Filed: 1978-07-11
Granted: 1982-09-14
Abstract: ABSTRACT OF THE DISCLOSURE In chroma-key tracking systems it is known to compress and insert a second television picture into an area corresponding to a chroma-key frame located at a specified position in a first television picture.  When the frame is shifted, there is a time lag before the compressed picture shifts correspondingly.  In that interval, the second picture is compressed to in-clude the unused and noisy component of the shifted frame.  A poor picture results.  The present invention describes a chroma-key tracking system which prevents the generation of this unnecessary and noisy component of the shifted frame.  A key signal is generated which represents the chroma-key frame and which is positioned in the first picture.  A position signal, pro-duced in response to the key signal, determines the position of a frame cir-cumscribed about the key frame.  An imaginary frame is produced in response to an imaginary-frame position signal to be greater in size than the key frame.  A compressed second picture is produced from a compressed second video signal which in turn is a function of a second video signal and the imaginary-frame position signal.  The second picture is compressed to be identical in size to the imaginary frame.  The first video and second com-pressed video signals are then gated in response to the key signal with the result that the compressed picture is inserted into the chroma-key frame in the first picture.
