Filed: 1972-08-22
Abstract: 1400911 Exponential multipliers UNITED AIRCRAFT CORP 22 Aug 1972 [29 Dec 1971 25149/73 Heading G4G [Also in Division H4] A circuit for processing a video signal for application to a CRT display comprises a differential amplifier 14 having one input 56 connected to a D.C. level-setting device (e.g. a potentiometer 10) which determines brightness, and the other input connected to a gammacorrection circuit 10b incorporating a contrast control 12. The circuit 10b is an exponential function generator and comprises transistors 22, 28, the bases of which are connected to a common current source 36 by respective diodes 32, 34, and the emitters of which are connected to a second common current source 38 by respective diodes 60, 62 (all diodes consist of base/collector connected transistors). It is shown that by providing a switched variable impedance 90 between the emitters and further diodes (not shown) in series with diodes 60, 62, the circuit can be adjusted to provide values of gamma variable between unity (linear condition) and <SP>1</SP>/ 3 . The current sources 36, 38 are temperature corrected by a diode 100. The gain of the circuit determines contrast and may be adjusted by variation of resistor 98. For automatic contrast control responsive to ambient conditions, the resistor 98 is combined with a photosensor.

Title: Improvements in or relating to platen printing presses
IPC: B41F1/52
Filed: 1932-09-09
Abstract: 387,272. Inking-apparatus. SCHNELLPRESSENFABRIK AKT.-GES. HEIDELBERG, Heidelberg, Baden, Germany. Sept. 9, 1932, No. 25154. Convention date, June 4. [Class 100 (ii).] In a platen printing-press having inkdistributing rollers which are moved to and fro over the printing-bed, the distributing-rollers are arranged so that they can be shifted independently of the spreading-rollers of the inking- mechanism, so as not to touch the surface of the inking-cylinder during their reciprocating movement, while running-in the inking mechanism. Ink is transferred to the inking-cylinder from the fountain 7 by rollers 4, which are mounted in a roller chair 19 and can be moved away, as shown in the Figure, by a hand-lever 20 and distributing-rollers 9, mounted on swinging arms 10 which oscillate about a pivot 12, transfer the ink from the cylinder 8 to the bed 2. The rollers 9, which are normally pressed against the cylinder 8 and bed 2 by springs, are provided with running rollers which engage running rails 14 arranged on both sides of the bed. At the upper end a guide rail 141 is pivotally connected with each of the rails 14 by a pin 15, and to the upper end of the rail 14<1> is attached a guiding link 16 which connects the guide rail with a hand-lever 18 rotatable about the pivot 17. In normal operation, the rollers 9 roll down upon the inking-cylinder, and during the downward swing of the arms 10 the running rollers run along the guide rails 14<1>, 14 to ink the bed 2. For running-in the inking-mechanism before printing, the hand-lever 18 is raised to rock the guide rails 141 out above the periphery of the cylinder 8 to the position shown, so that the distributing-rollers 9 not longer. contact this cylinder during their reciprocatory movement.

Title: Method and structure for connecting attachments to fiberglass rods
IPC: B29D23/00
Filed: 1970-05-26
Abstract: 1300265 End connections for fibre glass rods NUPLA CORP 26 May 1970 [20 June 1969] 25194/70 Heading D1T A fibre glass rod 10 is secured in an end fitting 17 by passing the rod through the fitting 17, splitting the end of the rod into a plurality of substantially equal segments 11, separating the segments 11, and inserting a plug 12 between the segments 11. A barrier tape 16 is then wrapped around the segments 11 to define a mould and the resulting body is lowered into the fitting 17. A lower elastomeric plastics seal 20 closes the fitting 17 where the rod 10 protrudes. A potting resin 13 is then poured into the chamber formed by the tape 16 and into the space between the tape 16 and the fitting 17. The tape 16 is substantially non-adhesive with respect to the potting resin 13 and acts as a slip plane. A lubricant may be used on either or both surfaces of the barrier fitting 16 and/or on the inner wall of the fitting 17. In a modified construction the tape 16 is avoided by placing a tapered mould temporarily around the segments 11 whilst potting resin is poured between the segments Thereafter the mould is removed, a lubricant or release agent is applied to the outer surface of the tapered casting 13, the tapered casting is lowered into the fitting 17 and further potting resin is poured into the space between the fitting 17 and the tapered casting 13.

Title: Continously Operating Screw-Type Centrifuge
IPC: B04B1/20
Filed: 1968-05-27
Abstract: 1,197,128. Centrifugal separators. TURBOSEPARATOR A.G. 27 May, 1968 [2 June, 1967], No. 25326/68. Heading B2P. In a screw centrifuge for separating abrasive solids from a machine-tool cooling liquid contained in a tank 15 disposed below the centrifuge housing 1, a solids-discharge screw 9 fixed to a drive shaft 8 extends through a rotatable centrifuge drum 2 into the tank for delivering the mixture of solids and liquid to be separated to the drum, the discharge screw and the drum being operatively connected by means of a unidirectional freewheel coupling 10 and braking means being provided for periodically braking the drive shaft during operation so that the speed of rotation of the discharge screw lags at periodic time intervals behind the speed of rotation of the drum. The discharge screw 9 has a funnelshaped extension 13 provided with blades 14 which serve to pump the solids-liquid mixture from the tank 15 into the drum 2. The screw threads of discharge screw 9 are carried by a spider 1 between the arms of which the solidsliquid mixture passes towards the wall of the drum 2. Solids discharged by the screw fall through an annular shaft in the tank 15 into a removable drawer 22, while the separated liquid is forced through passages 18 into a chamber 19 from which it is withdrawn under pressure. The shaft 8 is driven by an electric motor 11 via a belt 12. Periodical braking of the shaft 8, and hence of the discharge screw 9, may be effected by controlled reversal of phase of the electric motor, the control being effected by an adjustable timing relay 20, or by a periodically controlled mechanical brake acting directly on the drive shaft. The braking frequency may be controlled as a function of the quantity of solids separated or to be separated. One or, as shown, a number of spring-loaded cone valves 23, Fig. 3, are arranged in the centrifuge drum wall which, during operation of the centrifuge, are closed under the action of centrifugal force but which open automatically at a given speed of rotation below the operating speed so that when the centrifuge is shut down the liquid does not flow back through the drum into the drawer 22 but is discharged through the valve openings.

Title: Improvements in or relating to purification of c to c alcohols by extractive distillation
IPC: C07C29/74
Filed: 1953-09-16
Abstract: A slightly water-soluble C4-C6 alcohol is separated from a mixture containing, in addition to the alcohol, a C8-C12 hydrocarbon, which tends to form an azeotrope with the alcohol, by a process which comprises subjecting the mixture to an extractive distillation using as the extraction solvent an aqueous solution containing from 20 to 80 per cent by weight of a water-soluble hydrotropic salt of an organic acid.  Suitable salts are those of organic compounds containing an alkylaryl group and a polar substituent such as a sulphonic acid radical, e.g. sodium xylene sulphonates and sodium p-cymene sulphonate.  In the examples an oxo amyl alcohol, formed by the reaction of carbon monoxide and hydrogen with butylenes followed by hydrogenation, and contaminated with hydrocarbons is extractively distilled in the presence of an aqueous solution of sodium xylene sulphonate; 4-methyl nonane and 3,5-dimethyl octane are obtained in addition to the purified alcohol.ALSO:A slightly water-soluble C4-C6 alcohol is separated from a mixture containing, in addition to the alcohol, a C8-C12 hydrocarbon which tends to form an azeotrope with the alcohol, by a process which comprises subjecting the mixture to an extractive distillation using as the extraction solvent an aqueous solution containing from 20 to 80 per cent by weight of a water-soluble hydrostropic salt of an organic acid.
