Title: Improvements in or relating to photographic document copying apparatus
IPC: G03B27/50
Filed: 1953-05-29
Abstract: 725,883. Photographic document copying apparatus. KODAK, Ltd. May 29, 1953 [May 29, 1952], No. 15002/53. Class 98 (1). Relates to interchangeable mounts for photographic document copying apparatus of the kind in which means is. provided for moving a document continuously through the apparatus to enable it to be photographed by an objective on to a film strip which is continuously moved through a driving roller through the focal plane of the objective at a speed co-ordinated with the speed of movement of the document. Each mount supports an objective and uses a film driving roller for presenting the film to the focal plane of the objective, and is provided with means which prevents proper operative connection to a driving shaft within the apparatus of a film driving roller which positions the film in front of or behind the focal plane of the objective. As shown, the film driving shaft 28 is journalled in a bearing 31 mounted in a plate 32 secured to the bottom wall 34 of a compartment for the film driving mechanism. A member 38 and rollers 40 in a recess 41 permit rotation of shaft 28 in one direction only. The mount 45 comprises a mounting plate 46 and a support 47 for the objective 14. The plate 46 has a cylindrical boss 43 entering an aperture 42 in plate 32. The film driving roller 15 consists of a cylindrical member 60 to which flanges 63, 64 are attached. The lower flange 64 has a sleeve hub 67 protruding into the boss 43. The upper end of shaft 28 has a portion 62 of reduced thickness which enters a bore in roller 15, the hub 67 embracing the thicker part of the shaft. The upper part of the shaft is split, and is threaded to receive a screw 72 with a conical thread. When roller 15 is in place, screw 72 is screwed up and causes the end of shaft 28 to expand to attach it thereto. The objective 14 forms an image of the document to be copied on the surface of a film F passing round roller 15 and gripped by layers 66 of rubber or the like. When a different degree of reduction is required, the mount 45 is replaced by another mount bearing a different objective of different focal length at a different distance from the axis of shaft 28, and roller 15 is replaced by a roller of different diameter. The objective support 47 extends almost up to roller 15, so that a roller larger than that required for the objective in use cannot be mounted. The diameter of the sleeve hub 67 and the internal diameter of boss 43 are chosen so as to increase as the roller diameter decreases, in a set of mounts and rollers. This prevents a roller of smaller diameter than is required from being mounted. If a roller is put on upside-down, the hinged lid 35 of the compartment cannot be closed because the sleeve hub 67 then extends upwards. In modifications, the rollers carry pins at different radial distances or of different sizes which move in corresponding recesses or annular slots in mounting plate 46.

Title: Improvements in or relating to gain indicating and measuring apparatus in carrier current transmission systems
IPC: H04J1/16
Filed: 1946-05-21
Abstract: 626,701. Current and voltage measurements and measuring apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TERRONI, T. B. D., and CANNON, J. R. May 21, 1946, No. 15306. [Class 37] [Also in Group XL (c)] An arrangement for indicating the gain/frequency characteristic in a carrier transmission system involving a modulator or demodulator comprises separate input circuits for the audio frequency signal, and the corresponding side frequency signal, each input circuit including a variable gain device, the output from one variable gain device being maintained constant, and corresponding changes being introduced by the other variable gain device, the outputs from the two variable gain devices then being compared by a centre-zero instrument. In the circuit shown in Figs. 3 and 4, the audio-frequency signal is applied at A to the input of variable mu amplifying valve VB, the output from which is fed through transformer TD and rectified so that a steady DC voltage appears across condenser C11. Similarly, the corresponding side-band frequency is applied at SB to valve VA, whereby a steady D.C. voltage is produced across condenser C10. Meter MA measures the difference between the two voltages and so indicates the gain. The signal at the input of valve VA is also fed via condenser C12 to automatic gain control valve VC, whereby a voltage is produced across resistance YA which is used to control the gain of valves VA and VB. For calibration purposes, switch CAL which shunts meter MA is provided and the audio frequency only is then applied. Gain control VR3 is adjusted until the meter gives a predetermined reading ; the shunt is then removed and the side-band frequency applied, and gain control VR1 adjusted until the meter reads zero. A switch S1, S2, S3 is provided which in conjunction with potentiometer YP, YQ, YR enables a gain of plus or minus 0.9 decibels to be introduced. Other positions of switch S1, S2, S3 also enable either a 600 ohm or a high impedance to be provided at one or both inputs. The audio frequency may be continuously variable, so that the change in gain over the range of frequency may be measured. The gain control voltage may be applied to two variable loss networks in place of valves VA and VB. Buffer amplifiers may be provided in each channel.

Title: Process of treating dye effluents
IPC: C02F1/52
Filed: 1926-06-18
Abstract: 262,382. Darco Sales Corporation, (Assignees of Mahler, P.). Dec. 3, 1925, [Convention date]. Treating-materials.-Effluents from dye works are decolourized by treatment with activated carbon, for example that sold under the Registered Trade Mark " Darco," the carbon after separation from the liquid being revivified for reuse. A precipitating agent may be used to assist in the decolourization and to cause the settlement of the carbon. A precipitate may be produced by the successive addition of milk of lime and alum or iron or chromium salts. The carbon is added at or immediately after the formation of the flocculent precipitate. Instead of a flocculating agent, a salt which will transform the ayes from a colloidal to a molecular state may be used. The treatment is preferably carried out at near the boiling-point. When relatively small volumes of effluent are treated, and particularly where the dyestuffs are more concentrated, a precipitant is not necessary, but filter aids, such as diatomaceous earth, may be used with the activated carbon, which is separated by filtration. The carbon may be revivified by means of an oxidizing agent such as a chlorate or hydrochloric acid, but where it is desired to recover the dye the mixture is lixiviated and the carbon separated.
