Title: Facsimile signal inverters
IPC: H04N1/028
Filed: 1952-05-02
Abstract: 731,824. Copying-telegraphy. CREED & CO., Ltd. May 2, 1952 [May 7, 1951], No. 11148/52. Class 40 (3). A signal inverter for optical facsimile transmitters comprises a box-like structure forming a chamber and means carried by the structure for directing two parallel beams of light through the said chamber to a photo-cell, the means including a lens tube in the path of the scanning beam and a polaroid device in the path of the other beam and rotary means for adjusting the intensity of the other beam in relation to the other beam and utilizing the regulated beam in conjunction with the scanning beam to obtain inversion of the picture signals. The regulated beam and the scanning beam are arranged to be equal so that with the incorporation of a lightchopper arrangement the constant signal results from the scanning of a white portion, whilst a signal varying at the chopper frequency results from the scanning of a dark portion. The scanning beam passing through tubes KT, PT is directed through an aperture 79 in a disc 78 fixed in the rear wall 64 of the casing, and the regulated beam passing through the polaroid device is reflected by the surface 95 of a prism 93 fixed to the rear wall 64 to pass through an aperture 96 in a plate 97 slidably and adjustably mounted in channel parts 98, 99 fixed to the wall 64. The polaroid device comprises a plate 82 of polarizing material held by a spring member 80 and a second plate 85 carried by a cylindrical member 84 rotatable in an opening 83 in the side wall 63 and clamped in adjusted position by a screw 90 engaging a plate 88 with a fork 88<SP>1</SP> located in a peripheral groove 89 in the member 84. In operation, the scanning beam from source 114 impinges on the space 115<SP>1</SP> between the teeth of the chopper disc CD when the regulated beam covers the teeth 115, and vice versa. When a white portion is being scanned, the beam of light falling on the photocell PC is substantially uninterrupted and constant, but when a dark portion is being scanned the scanning beam is reduced substan. tially to zero so that the light beam falling on the cell is interrupted at the chopper frequency and produces a signal which is amplified by the valve 120.

Title: A process for the preparation of azelaic acid semi-ester suitable for making civetone dicarboxylic acid
Inventor: NAYAK ULLAL GOVINDRAJ
IPC: C07C59/105
Filed: 1958-04-10
Abstract: Azelaic acid semiester is prepared by oxidizing a dihydroxy-stearic acid ester to a semialdehyde ester of azelaic acid by mixing and stirring a solution of the ester in a watersoluble organic solvent, such as methyl or ethyl alcohol, with an alpha-beta glycol rupturing agent such as sodium metaperiodate, followered by distillation, and oxidizing the semialdehyde ester thus obtained to azelaic acid semiester by treating an acetone solution of the semi-aldehyde ester with an aqueous solution of potassium permanganate in the presence of an acid, such as acetic acid.  The dihydroxy stearic acid ester starting material may be prepared by treatment of oleic acid or ethyl oleate with hydrogen peroxide in acetic or formic acid in the presence of sulphuric acid as a catalyst to give p 9,10-dihydroxystearic acid which is then esterified.  The azelaic acid semiester prepared as above may be treated with thionyl chloride to give the acid chloride, and the latter on reaction with a tertiary amine is converted to a dimer which on saponification with alcoholic potash and subsequent acidification gives civetone dicarboxylic acid. Alternatively, the dimer is boiled with aqueous alcohol to give the ethyl ester of civetone dicarboxylic acid which is useful for the preparation of civetone and dihydrocivetone.

Title: Video output amplifier
IPC: H04N9/64
Filed: 1971-04-27
Abstract: 1388544 Transistor video amplifiers RCA CORPORATION 24 April 1972 [27 April 1971] 11561/71 Heading H3T The series resistor 32 coupling the output of a transistor amplifier 16 to the input electrode of a CR tube is also included in the feedback path and causes (e.g. by co-operation with the capcitance at collector 18) arc voltage pulses from the tube to arrive at the output of the amplifier after the arrival via the feedback pack at the input. Thus, for positive arc voltages the transistor is conducting by the time the arc voltage reaches the output of the amplifier and damage is prevented. In the circuit shown a second stage 18 is included between the output of transistor 16 and the tube. Negative arc voltages are limited in the feedback path by diode 38 but cause the base of 16 to be saturated and thus both transistors to be conductive when the arc voltage reaches the output. Transistor 40 clamps the black level.
