Title: Systems of transmission for television and the like systems
IPC: H04N5/38
Filed: 1939-03-31
Abstract: 527,102. Modulation systems; television. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1939, No. 10115. Convention date, May 12, 1938. [Classes 40 (iii) and 40 (v)] In a television signal transmission system, the carrier amplitude is varied in accordance with the average level of the signals by means of a control potential obtained by peak rectification of the signals. Carrier from oscillator 3 is supplied in opposite phase to the suppressor grids of valves 1 and 6, and adjustment of resistance 8 and balancing condenser 7 results in elimination of unmodulated carrier in the common anode circuit. Television signals are applied to the grid G11 of valve 1 over condenser 11, and result in the production of modulation sidebands which are transmitted through filter 9 and amplifier 2 to the load circuit 19. A rectifier 13, connected to the output of the sideband filter 9, produces a voltage across resistance 14 dependent upon the peak value of the signals measured in the direction of the synchronizing impulse, and this voltage is fed over a resistance condenser combination 15, 16, of suitable time-constant to the suppressor grid of valve 5. This valve, whose control grid is connected to oscillator 3 over phasing network 18, feeds pure carrier, whose amplitude is controlled by the output of rectifier 13, to the load circuit 19. The phase of the added carrier may be the same as that of the suppressed carrier or may be changed by 180 degrees, in which case the signal will be reversed at the receiving end. In a modification, Fig. 6 (not shown), suitable only for positive television signals, a carrier suppression modulator of the form shown is used, but the peak rectifier is fed with the original signals and the rectified voltage is applied to the control grid of valve 6 to upset the balance and so produce the added carrier current in the load.

The crude solution may be a cephalosporin C-containing fermentation broth or filtrate thereof, a partially purified or concentrated broth extract, or a reaction mixture containing cephalosporin C. The carbon, preferably a steam or zinc chloride activated charcoal, may have a particle size of from 1À68 to 0À29 mm. and a surface area of 600-1500 m.<SP>2</SP>/gm. It is suitably contained in a column, the crude solution being applied thereto at about pH 5-6. Alternatively the solution may be contacted with batches of carbon, decanted and the carbon adsorbate then put into a column for subsequent elution. The eluent is a mixture of water and organic solvent in a ratio of 15 : 1 to 1 : 3 by volume depending on the nature of the solvent, which is brought to an alkaline pH (e.g. 9À5 to 12À0) with an inorganic or organic base (e.g. NaOH, KOH, Mg(OH) 2 , Ca(OH) 2 , NH 4 OH or a tert-amine). The solvent may be a C 1 -C 5  alcohol, a C 3 -C 4  ketone, a C 2 -C 7  alkyl ester, or a cyclic ether such as dioxan or tetrahydrofuran. It is passed through the column of cephalosporin C-carbon adsorbate, preferably at a space velocity of 0À1 to 2À0 per hour, and fractions containing cephalosporin C (e.g. detected by antibiotic acitvity or monitoring the optical density at 260 mÁ) are collected. The cephalosporin C eluate may be freed from salts by ion exchange resin treatment and crystallized by concentration or may be isolated as a salt (e.g. of Na or K). The carbon left after elution may be recycled for repeated use in the process. A fermentative production of cephalosporin C using Cephalosporin acremonium ATCC 14553 is described.

Title: Improvements in shrinkable caps for closing containers
IPC: B29D99/00
Filed: 1936-04-08
Abstract: Shrinkable caps for containers such as cans, wine bottles, scent bottles, medicine bottles, glass butter-containers, conserve pots, infants' feeding bottles, or tubes are produced by forming a film on a mould of the desired shape by immersing the mould in a solution of polyvinyl alcohol or a derivative thereof capable of swelling in water, reducing the film to substantially uniform thickness by rotating the mould, solidifying the film and removing the same from the mould.  Part of the film may be strengthened by immersing part of the mould more than once.  Suitable solvents include hydrophobe liquids which have not too low a boiling point. Suitable polyvinyl alcohols or derivatives include polyvinyl alcohol, esters, acetals and ethers thereof or mixtures with each other, with other polymerization product or interpolymerization products.  Substances promoting swelling, softening agents, filling agents or dyestuffs, such as glycerine, glycol, pigments, bronze powder, yellow mica, aniline dyestuffs, may be added.  In an example, a cap is made from a solution of a formaldehyde polyvinyl acetal in benzene, alcohol and methylene chloride--opaque caps being prepared if moisture is not excluded during drying and clear caps if hydrophobe liquid with not too low a boiling point, such as chloroform, or pentachlorethane, is used as solvent.  Printed matter may be applied to corks or printed paper strips may be placed under the caps and remain visible or the cap itself may be printed or provided with a transfer picture.  The Specification as open to inspection under Sect. 91 refers in general to the manufacture, from polyvinyl alcohol or its derivatives, of covers and wrappers, such as wrappers for bottles (such as babies' bottles), cigarette or confectionary packages, for cigars, fruits, chocolate tablets, pipes, smoked fish, artificial skins for sausages, envelopes for gases such as air balloons, capsules for enclosing liquids such as medicants.  In an example, an artificial sausage skin is made from a formaldehyde polyvinyl acetal.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to electric analogue computers
IPC: G06G7/22
Filed: 1959-03-25
Abstract: 921,773. Transistor limiter circuits. GENERAL PRECISION Inc. March 25, 1959 [March 25, 1958], No. 10382/59. Class 40 (6). [Also in Group XXXVI] A transistor limiter circuit comprises two transistors, an NPN transistor X103 and a PNP transistor X104 having their emitters connected at 106 and their collectors connected to D.C. voltages +Vy and - Vy, respectively. Assume that the alternate positive and negative pulses of 10 volts amplitude are applied to the bases of the transistors and that the amplitude of Vy is 6 volts. As the leading edge of the input pulse rises positively from zero NPN transistor X103 acts as an emitter follower, transistor X104 which is cut off due to the positive voltage at its base, acting as the load impedance for X103. The voltage at 106 will therefore follow the input voltage until the latter reaches and begins to exceed +6 volts. The collector-base junction of transistor X103 becomes forward-biased so that transistor X103 conducts and terminal 106 remains very nearly at 6 volts as long as the input to the base exceeds this voltage. On the trailing edge of the input pulse, as soon as the input reaches +6 volts, transistor X103 becomes an emitter follower again and the voltage at 106 will follow the input base drive voltage to zero. The negative pulse on the transistor bases will then cause transistors X103, X104 to switch over, X104 now becoming an emitter follower with X103 as its load impedance. The switching circuit thus limits the pulse amplitudes in accordance with Vy.

Abstract: 1,253,695. Feeding sheets. GESTETNER Ltd. 20 Feb., 1970 [26 Feb., 1969], No. 10419/69. Heading B8R. Detecting faulty feed.-Sheets being fed to a rotary duplicator are engaged by oscillating guide plate 34 and caused to depress sheet sensing member 24. If no sheet is present when guide plate 34 descends, member 24 is not depressed but is accommodated in a slot 35 of plate 34. Sensing member 24 is coupled to a rotary valve 25 such that if member 24 is depressed by the presence of a sheet the valve is closed and if the member is not depressed the valve remains vented to the atmosphere. Closing of the valve causes a pneumatic transmission to permit the duplicator pressure cylinder to be brought into engagement with the stencil cylinder in the normal manner. Non- closing of the valve due to the absence of a sheet prevents such movement of the pressure cylinder.
