Title: Improvements in or relating to phototypesetting apparatus
Inventor: O'BRIEN RICHARD CHARLES
IPC: B41B21/16
Filed: 1961-05-09
Abstract: 985,041. Photographic type - composing. HARRIS - INTERTYPE CORPORATION. May 9, 1961, No. 16832/61. Heading B6W. [Also in Division G2] Photographic type-composing apparatus comprises a character matrix and a primary optical system forming matrix character images on a photographic recording material, the optical system including means for controlling the size of the recorded image, means for producing relative movement between the optical system and the recording material in accordance with character image spacing requirements, a pi character plate having transparent and opaque portions defining a pi character, means for illuminating said plate, and light-deflecting means for directing as pi character imageforming light beam into said primary optical system and through said size controlling means to record the pi character in an appropriate size. As shown, the invention is applied to the machine disclosed in Specification 891,142, and the pi character, a pointing finger on a plate 115 is supported in a frame 119 to produce by means of a second optical system 122 a reduced image in the same point size as the characters on the matrix disc 10 at a distance X from a reflector 125 equal to its distance X<SP>1</SP> from the disc 10. Tabs or fingers 116 on the pi character plate, on insertion of the plate in the frame 119, close one or more of switches 118a . . . 118e to condition pentodes 130 (suppressor grids omitted as shown), which set the pi character relative width in binary code into the counter N of the width computer 42 of the above-mentioned machine, the desired point size being set in the counter P so that the output over line 45 represents the desired character width. When the pi character is to be recorded a switch is operated, e.g. from a push-button on the machine keyboard. This causes a switch 144 to close and operate a timer 142 controlling the lamp 120 for the pi character and also causes switch 138 to close on to the grounded contact, producing a negative pulse which has no effect. When the character has been recorded, the timer returns the switch 138 to the position shown producing a positive pulse which operates the pentodes previously conditioned by the closed switches 118 arid operates tube 150 to start the pulse generator 80. The character width is thus set up in the computer 42, and pulses are fed by generator 80 to the computer, the line length counter SM and the transducer feeding the photographic recording strip. When the computer 42 has received the appropriate number it emits a stop pulse over line 45 to the pulse generator 80, with the result that proper spacing is effected. The resulting record comprises a single line along the length of the strip which may be used to produce justified matter as in Specification 768,374. The reflector 125 may be either a full mirror on a carriage on rails so as to be withdrawable from the straight through light path or a half-silvered mirror.

Abstract: 1,078,976. Photo-electric light absorption measurement. DISTILLERS CO. Ltd. April 15, 1965 [April 25, 1964], No. 17262/64. Heading G1A. In a radiation fluid analyzer of the kind described in Specification No. 899, 973 for determining the concentration of water in acetone by the absorption of infrared radiation in an overtone wavelength absorption band where chopped reference and sample beams are passed alternately by means of a cylindrical chopper through reference and sample cells of acetone and acetone and water and the resulting amplified D.C. signals passed by means of a switch to respective channels of a two-channel D.C. ratio measuring device, the switch is a transistor switch having a neutral position and driven into one of one two switching states by one of two photo-diodes placed in the path of the corresponding chopped beam. Alternatively, both chopped beams or the single beam before division and chopping into reference and sample beams may be passed through a single cell through which the water and acetone solution is flowing. In both cases filters select the necessary absorption bands. The cylindrical chopper Fig. 2 (not shown) rotates about its longitudinal axis which is perpendicular to a beam from a tungsten filament lamp and has two main passage-ways disposed at right angles to one another to pass the reference and sample beam alternately. Each has a narrower adjoining passage-way which extends over a greater arc of the cylinder and passes radiation to the switching photo-diodes. A plate placed after the cylinder has two main apertures to direct the reference and sample beams to the sample cells and two subsidiary apertures after which are placed the two switching diodes which only receive radiation from the adjoining passage-ways. The extended arc enables the switching signal beam to lead and trail the corresponding reference or sample beam and thereby ensure that the transistor switch feeds the correct channel for the whole of the time the corresponding reference or sample beam falls on the detector. An A.C. coupled amplifier is used which has a D.C. restoration circuit succeeding it.
