[Also in Group XL (b)] Cathode-ray apparatus for transforming a television image having a given number of lines n 1 , into an image having a different number of lines n 2 , the image repetition fiequency remaining unchanged, comprises two double-sided targets I, II, an electron gun 1 for recording the images of n 1  lines, an electron gun 2 for analysing the charge patterns thus produced at n 2  lines, and two pairs of deflector plates 5 and 6 fed in opposite phase with squarewave voltage from a a generator 9 for shifting the scans at the termination of each image so that recording and analysing takes place alternately on each of the targets. The signals are derived at the signal plates of the targets, couplings 7 and 8 being switched electronically under the control of generator 9. The targets may comprise on the recording side a fluorescent material deposited on a transparent signal plate formed as a thin metallic layer, these two layers being supported on a leaf of mica or transparent alumina to the analysing side of which is applied a photo-mosaic. Alternatively the targets may comprise thin semiconductive films.

Title: Improvements in and relating to transistor circuit arrangements
IPC: H01L27/00

Abstract: 1,137,207. Semi-conductor circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 March, 1966 [30 March, 1965], No. 13286/66. Heading H3T. [Also in Division H1 Circuits are described using a transistor (see Division H1) having two ohmic connections to the collector region, thus defining separate current paths. The D.C. source is connected across the emitter and first collector contact 4, the large current flowing to. collector 4 causing a large voltage drop in the collector region. The output is therefore taken from the second collector connection 7 which is arranged to pass a smaller current so that only a small emitter-collector 7 voltage drop results. Fig. 3 shows a bi-stable circuit using an integrated circuit of two such transistors 21, 22 and diodes 23..... 26 as collector loads; trigger pulses being applied at 27, 28. R.C. speed-up or delay circuits may be included. An astable multivibrator may be formed by including an R.C. delay between each collector 7 and the other base. Fig. 4 depicts a wide-band amplifier in which no direct current flows in the feedback resistors 31 hence the feedback factor may be altered without changing the working points.

Title: Improvements in and relating to the manufacture of boards and other shaped articles from wood and other chips of vegetable origin
IPC: C08L97/02
Filed: 1966-03-25
Abstract: <PICT:1099088/C3/1> In making chipboard and the like, chips of wood, wood wool, straw or chaff are treated with impregnating and/or binding agents in a solution, dispersion or emulsion and then partly dried in a centrifugal strainer.  In Figure 2, the chips are added at 7 to a stream of impregnating agent entering the drum 2 by shoot 5 and partly dried before reaching pipes 11, 12 which deliver a binding agent and pipe 13 which delivers hot air.  The impregnating agent may be a solution of urea and sodium fluoride with some ammonium dihydrogen phosphate as a fireproofing agent and hardener for the binder; which may be urea, melamine or phenol formaldehyde or cresol-resol resin.  Movement along rotating perforate drum 2 is induced by reciprocating plate 4, and the drum may be of stepped construction to aid mixing and increase peripheral speed towards the open end.  The impregnating and binding agents could be mixed before adding to the chips.  In alternative methods the chips and liquor are mixed in a vat before entering the drum, or the chips may enter the drum dry in an air stream or vibrating trough, or the binder is added in a mixing step to impregnated and dried chips leaving the drum. Some constituents of the liquors may reduce adhesion to the drum wall.  Other constituents such as chlorinated paraffin wax, sorbitol and resorcinol may be added to the liquors.  The liquor withdrawn from the centrifugal strainer may be brought up to strength and recirculated.

Filed: 1928-05-09
Abstract: 307,867. Mondiale Typolitho Soc. Cooperative. March 15, 1928, [Convention date]. Letter-spacing mechanism.-In a differentialspacing mechanism for typewriters employed in preparing printing-surfaces, a friction-feed device connected to the carriage is operated by one or other of a number of universal bars which are operated differentially by the key-levers, selection of the operative universal bar being effected by means of a slide controlled by the shift mechanism. In the machine shown in Figs. 1 and 2, the carriage 3 is provided with a feed device comprising rocking arms 47, 48 supporting a pivoted shoe 52 which engages a disc 51 on a shaft 50, a cord 62 wrapped round a grooved drum 60 on the shaft being connected at both ends to the carriage. The arm 47 is connected by a cord 77 to a spring drum 78, and a pin 46 on the plate arm engages an arm 45 on a shaft 41. The key-levers 23 operate type-levers 10 and have shoes 38 engaging projections 39 of graded heights on universal bars 34, 35 carried by shafts 36, 37. The universal bars co-operate with a member 44 on a slide 40 mounted on a plate 40<a> secured to the shaft 41. The slide engages a lever 72 abutting on a rod 71 which engages a cam 70 on the shift frame 5 supporting the platen 7 and feed-rollers 8, movement of the shift frame causing the member 44 to move from one universal bar to the other.
