Filed: 1944-03-13
Abstract: 574,157. Embossing processes. McGILL. J. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 13, 1944, No. 4605. [Class 100 (ii)] A process for impressing a design on a sheet coated with a gelatinized polyvinyl chloride composition comprises softening the surface as by subjecting it to the action of radiant heat, and while the coating is soft passing the sheet through a cold metal roll bearing the design in reverse and a coacting cotton bowl formed with a slight camber and adapted to exert a uniform but light pressure over the sheet. The material may be gelatinized. before or during the process, and in the latter case the polyvinyl chloride may be mixed with a plasticiser, and if desired a pigment before being heated. A steel engraved water-cooled roller may be used, and a paper bowl of 54" diameter, and length 55", with a diameter difference at the centre of 1/32'' may be used to produce a pressure of 40 lbs. per inch of material being treated. In one example a length of fabric coated with a composition containing equal parts by weight of polyvinyl chloride, tricresyl phosphate, and iron oxide pigment was treated as described above. A two-colour effect may be obtained by embossing the fabric in the first place by means of a hot calender roller and applying a thin coating of pigment sufficient to tint the hollows. The fabric is then subjected to heat on the coated side, and subjected to a cold embossing process as above.

Title: Method and apparatus for short-circuit arc welding
IPC: B23K9/10
Filed: 1975-02-05
Abstract: 1448188 Welding by fusion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Feb 1975 [8 Feb 1974] 4866/75 Heading B3R [Also in Division H2] In short circuit arc welding using a consumable electrode wire 6 to weld a workpiece 7 a period Td is provided between short circuit contact of the wire and the workpiece and a short circuit current flowing to melt off a bead produced by the arc. In apparatus (Fig. 3) for carrying out this method a first power source 1a having a noload voltage higher than the arc voltage strikes the arc between the wire 6 and the workpiece 7. The arc voltage is detected in line 14 of a control unit 12 and a timing circuit is triggered. After an interval Tb a silicon controlled switch 4a is switched by the unit 12 so connecting a second source 1b of voltage lower than the arc voltage. The first source 1a drains into a resistor R2 and a capacitor C associated with the second source causing the arc to be extinguished. As the wire 6 is being constantly fed from a reel (10) short circuit contact, after a time Tw, is made between the wire 6, now having a bead at its tip, and a weld pool 8. The contact is detected by the unit 12 and a second timing circuit is triggered which after the time period Td triggers rectifier 4b so allowing a short circuit current from the source 1b to flow to the wire so melting off the bead into the weld pool. The arc is restruck and the cycle repeated. In a further embodiment (Fig. 4, not shown) a diode replaces the rectifier 4b and a rectifier is connected between the electrode and the supply 1a in order that there is no current in the short circuit zone during delay Td. In Fig. 1 (not shown) both arc current and short circuit current are supplied by one source.

Class 100 (4) A hectograph tape feeding mechanism comprises two supports 13, 14 mounted on a base member 10-12 on which a typewriter may be placed; the support 14 carries a supply spool 18 and the support 13 a take-up mechanism which draws the tape 27 past the typing position. The tape is fixed relatively to the typewriter carriage during letterspacing movement by means of a guide 29 but during a carriage return movement the tape 27 is held by the take-up mechanism and slides relatively to the guide. The parts 11, 12 of the base member are hinged on rods 25 which provide two fixed guides between which is located the typewriter upon a pad 26. Part 12 mounts a column 14a adjustably carrying the support 14, and the spool 18 rotating thereon is formed with a removable upper flange to enable a ribbon to be fitted. The lower flange of the spool is engaged by spring mounted sponge rubber which acts as a friction brake. The tape 27 is fed across the printing line of the machine where it is positioned by a guide member 29 attached to the carriage at 40; the guide member 29 is formed from thin metal sheet with two strips 32, 33, Fig. 5, providing between them a guide channel for the tape. At each end of the guide are a pair of fingers 34 and an intermediate portion 35 around which the tape is threaded so that it holds it so that the tape and carriage move together in a letter-space direction. The guide member 29 may be formed with closed slots in place of the parts 34, 35 and the strips 32, 33 bent to form a channel for the tape 27 ; the lower edge 36 of the guide 29 is provided with a knife edge so that a master sheet will pass in front of the guide. When the carriage travels in the return direction the guide member 29 slides along the tape 27 which is held against backward travel by the take-up mechanism on the support 13. This mechanism comprises a feed roller 47, Fig. 3, freely mounted on a shaft 41 urged in a tape-feeding direction by a weight 44 and pulley 42, the drive from shaft 41 being transmitted to the roller 47 by a ratchet wheel 50 and a pawl on the side of the roller 47. The pulley 42 winds up the weight 44 during a carriage return movement by rotation of a pulley 45 driven by a tape 46 attached to the typewriter carriage. During this direction of rotation of shaft 41, roller 47 is held stationary by a pawl 49 engaging a ratchet 48 fixed to the roller 47. A pressure roller 52 formed of rubber or cork is mounted on a lever arm 56 and urges the tape 27 into contact with the roller 47. The Provisional Specification describes the roller 52 as being mounted on a bracket slidably mounted on the support to facilitate the initial threading of the tape. The bracket is fixed in operative position by a locking screw.

Abstract: 1278392 Digital transmission systems; majority decision sampling COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 18 Feb 1971 4921/71 Heading H4P In an apparatus for sampling, by majority decision, signals presented in terms of a matrix array with Q lines which are divided into perpendicular zones of h bits per line with the probability p of an erroneous bit, a first shift register 12 with h positions receives the signals sequentially which are parallelly transferred at determined intervals into a buffer memory 14 of capacity nhQ bits, with an array of n cascaded shift registers 14 each having h divisions with a majority decision circuit 15 sampling the output bits of each register. The arrangement transfers at least parts of the buffer memory content at determined intervals through register 12 to register 14 for presentation to the majority decision circuit. A television frame 10 with Q lines and vertical zones each of h bits has signals from each zone presented successively to a threshold circuit 11 which classifies signals above or below a determined blackness into digital signals of opposed type which are fed to input A of shift register 12 and transferred at determined intervals through memory 13 to the array of shift registers 14a-14n, the output bits from which are sampled and passed to 16 which provides a corrected video signal. Buffer memory 13 is preferably a circulating memory with a transfer circuit 19 having h divisions transferring content of register 12 to the input of circulating memory 21 which is suitably a delay line, hence the original group h may be retransferred after a delay into register 12 and passed into array 14. Memory 21 may circulate the data for example five times.

Abstract: 1,027,681. Valves. BAXTER WOODHOUSE & TAYLOR, and E. H. TAYLOR. Jan. 18, 1963 [Feb. 8, 1962], No. 4939/62. Heading F2V. [Also in Division A5] Fluid flow between inlet and outlet ports 13, 14, Fig. 1, is controlled by a rigid diaphragm 4 co-operating with a knife-edge seat 3, which diaphragm is suspended from the valve casing by a tubular moulded-rubber member 7 with a single corrugation 8 and having annular mounting beads 9. A chamber 11, formed between the casing and diaphragm, is provided with a port 12 and whilst the pressure in the chamber 11 is greater than the inlet pressure the diaphragm remains seated. In a modification, the diaphragm 21 (Fig. 2, not shown) actuates a tilting-type valve 19 through a lever 23, which valve controls the flow of fluid from an inlet 35 to a space A beneath the diaphragm 21. A branch 36 from the inlet 35 leads to a chamber in which is a flexible diaphragm loading a plunger 31 that biases and limits the lateral movement of the valve 19. The valve 19 is operated either by a decrease of pressure in the space A or a pressure increase within the moulded rubber member 26. In another modification, an outlet valve 41 (Fig. 3, not shown) is incorporated with the diaphragm 21 so providing a valve for use in an oxygen mask or pressure helmet. An outlet passage 45 leads to the interior of a pressure suit, the pressure in the space A being kept above that in the outlet 45 by adjustment of springs 42, 46, which load the valve 41, and diaphragm 21, respectively. The mask is connected to the space A. In a final modification, the outlet valve comprises a disc confined in a cage and abutted by the end of the tilting-valve actuating-lever; a stop is provided to prevent the outlet valve moving with the diaphragm when the space A experiences a pressure increase.

Immunizing and like serums; bacteria, cultivating.-Cancerous or like tissue is treated with degradation or dissolving agents, such as ferments, so as to liberate the contained causative micro-organisms, from which cultures and immunizing and like serums or other preparations may be obtained in the usual manner. In an example, a cancerous tumour is comminuted and treated with trypsin solution at blood heat for 1 ¢ hours. The resulting preparation is spread on a nutrient medium such as agar and incubated for several days. The culture so obtained is purified by selection so as to obtain spore-forming rod-shaped organisms of defined staining characteristics. In place of trypsin the tumour may be treated with other ferments or enzymes such as pepsin, and erepsin, or with solvents for lipoids, or by hydrolysis with acids or alkalies, or with a succession of such agents. Pure cultures of the organisms may be obtained by aerobic or anaerobic methods, Curative serums may be obtained by injecting an animal first with cultures which have been killed and then with cultures of gradually increasing virulence, or killed or non-virulent cultures may be used for direct injection into the diseased organism.
