Abstract: ABSTRACT         A high frequency converter of push-pull form comprises a centre tapped D.C. input supply, two solid state switching devices connected in series across the D.C. input terminals, a load circuit including a supersonic frequency transformer and an output rectifier, and an oscillatory circuit including at least one capacitor and a parallel inductor connected in parallel with the primary winding of the transformer between the centre tapping of the supply and the junction of the switching devices.  The switching devices are synchronised to the oscillation of the oscillatory circuit to allow the circuit to oscillate freely for part of a cycle to transfer energy from the inductor to the capacitor to charge the latter to a certain condition in which the voltage across the parallel inductor is substantial and that across the switching device is negligible and only then connect the parallel inductor across the D.C. input terminals whereupon the parallel inductor receives and stores energy from the said supply.  Means such as a saturable reactor are connected in series in the load circuit to restrict load current to a low value during a part of the cycle in which the capacitor receives energy from the parallel inductor and until the capacitor is charged to the said condition and the switching means has connected the load circuit across the supply.  The converter is an improvement in that for a given output the delay on the switching devices is eased.

Abstract: SIMULATED FOOTBALL GAME                   Abstract of the Disclosure This game has a game board which simulates a football field and has regularly spaced openings for receiving player pieces.  Associated with the game board is a play selector with rotatably adjustable wheels located behind viewing windows and carrying indicia which designate, respectively, different types of plays, different directions in which the play may be run, and the identity of the ball carrier if the designated play is a run or the identity of the receiver if the play is a pass.  The yardage of the designated play is determined by rolling dice.  A separate manually operated chance device determines penalties, blocked kicks and incomplete passes.

Abstract: BLADE FABRICATING APPARATUS AND PROCESS BY INDUCTION HEATING        Abstract of the Disclosure A process and apparatus for cleanly and efficiently fabri-cating winged lawn mower blades from unfinished milled blade blanks.  The unfinished blades are positioned in a magazine and fed one after the other to a heating station where they are inductively heated from one side only to increase the effective thickness of material available to support the flux.  When a preselected temperature above the curie temperature of the blade metal is reached the blade is automatically moved to a press and hot-formed therein.  The blade then is delivered edgewise into an agitated non-polluting quench solution containing polyalkylene glycol and vigorously sprayed to assure a consistent Rockwell C hardness.  A conveyor delivers the blades from the quench tank to a tempering furnace for further heat-treatment.

Abstract: Abstract: Mixed phosphoric acid ester compositions are prepared by reacting at a low temperature in an an-hydrous system, and in the presence of a catalytic amount of sodium, an ester of phosphoric acid having the formula: wherein R1 may be the same or a different aromatic radical selected from the group consisting of phenyl and substituted phenyl radicals; with an aliphatic alcohol having the formula: R2CH2CH2OH wherein R2 is the same or a different aliphatic radi-cal selected from the group consisting of alkyl and alkoxy radicals. A transesterification mixture is obtained that contains a substantial amount of each of the compounds: R1O-?-(OCH2CH2R2)2 and (R1O)2-?-OCH2CH2R2 wherein R1 and R2 are the radicals defined above. The mixed phosphate acid ester composition may be separated from alcohols present in the transesterifi-cation mixture by distillation, and are useful plasti-cizers for polyvinyl chloride polymers.

Abstract: Sun-123(RUTH) INKER APPARATUS            ABSTRACT OF THE DISCLOSURE           Inker apparatus constructed primarily for the application of high viscosity paste-type ink includes an anilox fountain roll which partially defines an ink trough.  The latter is also partially defined by a scraper blade disposed downstream of a wiper blade which forces ink into the cells of the anilox roll.  The free edge of the scraper blade is disposed adjacent the cylindrical surface of the anilox roll to meter the quantity of ink which is removed from the trough by the anilox roll.  Two distributor rolls are used to transfer ink from the anilox roll to a plate cylinder.  One of the distributor rolls engages the image plate on the plate cylinder and the other distributor roll engages the anilox roll.  The latter distributor roll is oscillated axially so that the cellular pattern of the anilox roll will not be transferred to the first mentioned distributor roll.

Abstract: Title of the Invention A RAPID STARTER SWITCH FOR A FLUORESCENT LAMP          Abstract of the Disclosure An improved starter switch which provides a rapid firing of a fluorescent lamp within 0.8 second has been found.  The ex-ternal appearance and the size of the present starter switch are almost the same as those of a prior glow switch.  Therefore, the present starter switch may replace a prior glow switch by merely inserting the present starter switch in the socket of the glow switch.  The present starter switch has a connector cap which en-gages the socket for the glow switch, a printed circuit board mounting circuit components and connected to the connector cap by lead lines, and a housing fixed to the cap and covering the print-ed circuit board.  The circuit elements mounted on the printed circuit board include a non-linear capacitor which has a satura-tion characteristics between a voltage applied to the capacitor and the charge stored in the same, and a semiconductor switch which conducts upon the application of a voltage higher than a predetermined threshold voltage and holds the conductive status until the current in the same reaches almost zero.  Following the switching OFF of the semiconductor switch when the source cur-rent is almost zero but the source voltage is almost maximum due to the presence of an inductive ballast, the non-linear capacitor is charged but is saturated in a short time, then, the charge cur-rent of the capacitor is interrupted.  The interruption of the charge current of the non-linear capacitor induces a high firing pulse voltage in a ballast inductor which is connected in series with a fluorescent lamp, and this pulse voltage fires the lamp.

Abstract: ABSTRACT    Linear aromatic polyesters of bisphenols and dicarboxylic compounds are prepared by transesterification polymerization in either a fully continuous process or in a semi-continuous process wherein a first stage is conducted batchwise and a second stage is conducted in a continuous manner wherein the second stage employs a wiped film reactor, alternatively, a wiped film reactor followed by a vented extrusion reactor.          The processes are preferably conducted in the presence of a catalyst in liquid form, and further under conditions wherein th? catalyst is introduced to the polymerization concurrent with the introduction of liquid phase reactants to avoid sub-stantial heating of the reactants in contact with the catalyst prior to onset of the transesterification reaction.  The products of the processes have an unexpectedly low polydispersity.

Abstract: ABSTRACT OF THE DISCLOSURE   An electrooptical scanning device for deflection of an optical beam of light across an image plane. The device comprises a body of electrooptical crystal material and a periodic array of parallel, spaced electrodes associated with one surface of the body. A light beam entering the crystal body is caused to interact with electric fields established at the one surface by step applied voltages to the electrode array that influence the deflection of the light beam at the moment of total internal reflection at the one surface. By varying the magnitude of the applied voltages across the electrodes, a corresponding approximation of a desired phase retardation can be produced along the phase front of the light beam. The phase retardation across the light beam can be designed to produce a linear phase front angled beam or can be designed to produce a curvalinear phase front forming a focused spot at the image plane. With the changing of the magnitude of the applied voltages across the electrode array, the beam or spot may be made to move about or scan across the image plane.
