Title: Electronic flash circuit
IPC: G03B15/05
Filed: 1970-02-26
Abstract: 1292373 Electronic flash circuit PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Feb 1970 [1 March 1969] 9377/70 Heading G1A [Also in division G2] In an electronic flash circuit provided with an electronic flash-tube 5 and a photo-sensitive element 7, the duration of the flash is influenced by the quantity of light which is reflected on to the photo-sensitive element by the object to be photographed. The supply circuit of the flash-tube 5 includes two parallelly arranged thyristors 4, 9 each of which is connected to its own supply capacitor 3, 10, capacitor 10 having smaller capacity than capacitor 3. On ignition by switch 6 the thyristor 4 conducts and thyristor 9 is subsequently rendered conducting when the photosensitive element 7 has received a predetermined quantity of light. Owing to the higher potential of the capacitor 10, the thyristor then takes over the supply of current to the flash-tube 5 from the circuit containing the thyristor 4. The circuit is such that the period during which current flows through thyristor 9 and discharges condenser 10 is longer than the recovering time of the thyristor 4, so that the thyristor 4 is blocked and the direct current supply to the flash-tube 5 from the capacitor 3 is interrupted.

Abstract: 788,425. Discharging dyes in photographic films. GENERAL ANILINE & FILM CORPORATION. March 26, 1956, No. 9388/56. Class 98(2) Azo dyes used in the filter and anti-halation layers of black and white or colour film, particularly the latter when containing azomethine and quinoneimine dye images produced by colour development, are discharged by an aqueous alkaline bath containing a strong reducing agent and as a catalyst an N, N<SP>1</SP> - dialkyl, dicarboxyalkyl, or diaralkyl - 4, 4<SP>1</SP> - bipyridylium salt. Image dyes which have a tendency to reduce therein to their leuco forms may be restored by oxidation in the step of silver bleaching, or by an additional oxidation step if the filter dyes are discharged after removal of silver. In Example I a multilayer film having colour formers of the Fiat final report No. 943, a magenta filter comprising the dye made by coupling diazotized 3 - amino - 4 - octadecoxybenzene sulphonic acid with 1 - hydroxy - 8 - benzoylamino naphthalene- -3, 6 - disulphonic acid over the red sensitive layer and a yellow filter comprising the dye made by coupling diazotized 3 - amino - 6 - octadecoxybenzene sulphonic acid with 1 - (31 - sulphophenyl) - 3 - carbethoxy - 5 - pyrazolone over the green sensitive layer is exposed and processed by a fully specified sequence of operations of colour development, short stop, harden, wash, silver bleach in a ferricyanide solution, wash, fix, wash, filter dye discharge in a solution of sodium hydrosulphite, sodium bicarbonate and N, N<SP>1</SP> - dimethyl - 4, 4<SP>1</SP> - bi-pyridylium chloride; image dye restoration is the ferricyanide bleach solution and wash. In Examples II and III the same film is processed by a similarly specified reversal procedure, with a single step for silver bleach and dye image restoration following the bipyridylium filter dye discharge step in Example II. Examples IV and V use aminoiminomethane sulphinic acid (NH 2 .NH.C-SO 2 H), and stannous chloride respectively as the strong reducing agent in the dye discharge bath, and sodium formaldehyde sulphoxylate and sodium stannite are quoted also as reducing agents. The azo dyes of Specification 663,005 may be used as filter dyes and discharged similarly.

Filed: 1918-06-08
Abstract: 116,713. Vincnti, S. May 27, 1916, [Convention date]. Limbs, artificial.-A foot designed to prevent limping is so constructed that the rear portion is somewhat lifted at the moment when the foot is being lifted from the ground and whilst the front portions are lowered when the foot is about to be placed on the ground. The foot is connected to the leg by means of splints 1 carrying a rod 2 on which is loosely pivoted the rear portion 3 of the foot. A lever 15 is fast on the rod 2. The middle portion 5 of the foot is pivoted to the portion 3 by a joint 4 which allows only a very limited rotation. A toe piece 12 is pivoted to the middle part at 13. A pin 8 is carried by the member 5 and is engaged by a curved track 16, 17, 18 carried by the lever 15 and having its parts 16, 17 at a greater distance from the rod 2 than the part 18 so that, when the splints are inclined forward in the act of raising the foot, the track bears on the pin and causes the parts 3, 6 to rotate slightly as shown in Fig. 3. A number of springs 9 are attached near the pin 8 and are supported by rollers 10 carried by supports 11 secured on the rear part of the foot, and also have a bearing against rollers 14 carried by the toe portion. The effect described with reference to the lifting of the foot also takes place when the foot is placed on the ground, the splints 1 being inclined rearwardly and the part 17 engaging the pin 8.

Title: Improvements in or relating to knitting machines
IPC: D04B15/88
Filed: 1949-04-07
Abstract: 671,477. Knitting. MELLOR, BROMLEY & CO., Ltd., and SHORTLAND, A. April 6, 1950 [April 7, 1949], No. 9509/49. Class 74 (ii). Fabric drawing-off mechanism in a knitting machine includes single rollers having axially spaced peripheral projections of pointed formation adapted to penetrate and mesh with fabric to be drawn off, and means for operating the said drawing-off rollers individually so that they alternately roll idly over the engaged fabric in a direction towards the knitting needles and then move bodily, without rotating, in the opposite direction so as to exert a pull on the fabric for the purpose of drawing the latter off the machine. By reason of relative rotation, about axis a, between hubs 5 and 30, bell-crank levers 8 are rocked in one direction, about their pivots 23, by cam rollers 26 and are returned in the opposite direction by springs 9. During the first of these rocking movements, spiked draw-off rollers 16 run idly over the fabric towards the needles 24, 25 but, on the return movement, they are locked against rotation, by pawls and ratchets 21, 20 and so draw off the fabric. Carriers bearing the rollers 16 rotate with, or remain stationary with the needle beds, as the case may be. Carrier rods 6, 29 for the levers 8 and rollers 26 are radially adjustable. The tension in each spring 9 is adjustable by means of a screw 10 and nut 11, teeth. 11a on which are engaged by a spring blade 12. Each roller 16 consists of peripherally spiked discs 17 spaced by collars 18. Two, three, or four equi-angularly spaced cam rollers 26 may be provided. The rollers engage the fabric from the inside of the knitted tube, which is thus held open. The draw-off mechanism may be applied to a flat-knitting machine. According to the Provisional Specification, there is a cam roller to each bell-crank lever and the rollers are simultaneously operated.
