Abstract: 698,782. Photographic diazotype processes. CELLOPHANE SOC. ANON. Dec. 18, 1951 [Feb. 12, 1951], No. 29671/51. Class 98 (ii). A photographic. record is made by impregnating a translucent or transparent support as of regenerated cellulose, cellulose derivative or paper with a light-decomposable diazo compound, providing this with a surface image as of black ink by handwriting or typing, exposing on the side carrying the image to actinic light, and developing the remaining diazo compound to produce a positive photographic image within the support. The result is a permanent record which may be used as original in photomechanical reproduction processes and is not subject to the defect of flaking off of characters, which defect is found when a simple film-like support carrying written or type-written matter is used as original. A phenol in alkaline medium may be used as developer, or a phenol may be provided with the diazo compound for development by alkali, such as ammonia, alone. Impregnating mixtures may be (1) diazotized p-aminodiphenylamine and resorcinol; (2) pdiazo - N - ethyl - N - # . hydroxyethylaniline, 2: 3 - dihydroxynaphthalene and acetylacetanilide. The opacity of the ink image may be increased by causing carbon black to adhere thereto. Thin sensitized paper may be used as copy-sheet in a typewriter and treated by the process of the invention to produce a record for reproduction of further copies by transmitted light.

The washing with urea and mineral acid is preferably conducted at about 40 DEG  C. and is preferably preceded by a washing with water.  The mineral acid is preferably nitric acid and the concentration of the aqueous solution in contact with the alkyl nitrate is preferably between 1 and 3 Normal.  The urea and mineral acid are preferably employed in the form of the urea salt of the acid, e.g. urea nitrate, a saturated solution thereof being employed. The examples describe the purification of ethyl, isopropyl and secondary butyl nitrate.

The drive for a wheel 2 of a pallet conveyer is controlled by rollers 70, 71, 72 engageable with a V-belt 3. When an arm 69 which carries the rollers 70-72 is pivoted clockwise to its fullline position, the upper run 3<SP>11</SP> of the belt is freed from a pulley 5 fast with the wheel 2 and the lower run 3<SP>1</SP> is able to move away from the pulley 5 by gravity. With the arm 69 moved anti-clockwise the rollers 70, 71 urge the belt into driving engagement with the pulley. The belt also drives other wheels 2 of the conveyer. In Fig. 2, a sprocket 8 has a clutch member 84 engageable with the pulley 5, pressure being applied via a spring 82 and a ball-bearing 81, when a lever 74<SP>1</SP>, 74<SP>111</SP> coupled to the bearing by a link 77, is rotated to its broken-line position. In Fig. 3, a brake 86-88 for co-operation with the pulley is actuated by a bar 85, against tension of a spring 89. In use, a first pallet 18 may be stopped by manually operating the arm 69 (Fig. 1) and the clutch (Fig. 2). Switches actuated by this pallet may then cause successive arms 69, clutches and brakes to be operated to stop other pallets. The first pallet may also be stopped by electrical means.

Abstract: 1,232,844. Oscillator circuits. GENERAL ELECTRIC CO. 28 May, 1968 [31 Aug., 1967], No. 25486/68. Headings H3R and H3T. An oscillator circuit has a negative resistance device coupled to a circuit tuned to the fundamental frequency of the oscillator and also connected to harmonic impedances which control the frequency deviation from the fundamental of the oscillator according to change of the voltage bias of the device. In Fig. 1 a crystal controlled oscillator has increased frequency sensitivity by means of two parallel resonant circuits 36, 37 and 38, 39 tuned to successive harmonic frequencies connected across the negative resistance diode 8. Capacitor 33 has an impedance that is high at fundamental frequency and low at harmonic frequencies compared with that of the tuned circuits. Harmonic voltages produced in the harmonic tuned circuits increase the voltage across diode 8 and hence increase the frequency deviation for a given modulation of the bias. In the LC oscillator circuit of Fig. 2 greater frequency stability results from connecting series resonant circuits 40-41, 42-43 across diode 8, which produce low respective harmonic voltages thereacross. Fig. 6 shows a series resonant circuit 50, 80 tuned to the fundamental frequency and having a high impedance at harmonic frequencies. Frequency modulation is achieved by variation of inductor 50 or capacitor 80. Means are provided (not shown) for a D.C. current path around capacitor 80 in the embodiments of Figs. 3 and 6. Alternative combinations of LC or crystal oscillators with various resonant circuits are described.
