Abstract: 1,038,719. Apparatus for making bands of wrapping material. STRACHAN & HENSHAW Ltd. April 28, 1965 [April 29, 1964], No. 17877/64. Heading B5D. Devices 23, 24 (Fig. 2), grip the ends of a strip 25 of preprinted wrapping material cut from a continuous strip 12, and are then inverted (shown in broken lines in Fig. 2) and move towards each other so that the ends 26, 27 can be heat-sealed together to form a wrapping- sleeve. A photo-electric sensing device 20 stops the feed of the strip when the required wrapping length has been drawn between the jaws of a guillotine 18, In the embodiment described, the pre-printed strip 12 is fed on to the table 19 to the sensing device 20 which detects a register mark on the strip, previously printed on it at intervals corresponding to wrapper lengths by a coding unit 16, and causes the draw rolls 15 to be disengaged so that the feed of the strip 12 is stopped. After the wrapping-sleeve has been made it is removed from the apparatus by movement of the heat-sealing device 31 about its pivot 32 and dropped on to a conveyer or into a basket. To permit different sizes of bands to be produced the guillotine 18, sensing device 20 and gripping device 23, 24 are movable horizontally in the direction of the arrows 21, 22, 23 and 26 respectively. The gripping devices are inverted by a rod 29 which drives a part-circular gear 37, on which the device is mounted, round a fixed gear 41. The two jaws 46, 47 of the device are opened and closed by a toothed rack 52 driving quadrant gears 50, 51 on which the jaws are mounted. The rack 52 is reciprocated through an arm 58 by the action of a rocker 63 operated by a cam 67. The reciprocating sealing device 31 and sealing device jaws 33, 34 are also cam operated.

Abstract: 602,158. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co., Trivelli, A.P.H., and Smith, W. F.). June 14, 1946, No. 17915. [Class 98 (ii)] A sensitive silver halide developing-out emulsion is stabilized by the incorporation therein of a complex halide of ruthenium, palladium, or iridium. The halide may have the formula R2RuX6, R2PdX4, R2PdX6, R2IrX6, or R3IrX6, wherein R is H, alkali metal, or ammonium and X is halogen (e.g. Cl or Br). The compounds sometimes increase the speed, and in this case may be used in very small quantities. Details of speed, gamma, and fog values for additions of ammonium chloropalladite, and ammonium chloroiridite with a given developer under different conditions of storage are given. The stabilized emulsions may be developed with developers containing hydroquinone, p-aminophenol or its derivatives, pyrogallol, p-phenylenediamine or its derivatives, or phenylhydroxylamine. Other compounds that may be used are potassium chloropalladate, ammonium chlororuthenate, potassium and sodium chloropalladite, and ammonium bromopalladate. The compounds may be added before or during precipitation of the silver halide, before or during the first digestion (ripening), before or during the second digestion, or just before coating. Sulphur sensitizers (e.g. thiourea, allyl isothiocyanate, thiosinamine, or a metal, e.g. sodium, potassium, cadmium, or calcium, or ammonium thiocyanate, including one or more thiocyanates with a sulphur sensitizer other than a thiocyanate) may also be added. Both the compound and the sulphur sensitizer are preferably present during the second digestion, and the pH of the emulsion is preferably adjusted to between 5 and 7. The emulsions may be sensitized with any of the usual dyes. e.g. erythrosin, Congo Red, monomethine-, trimethine-, pentamethine-, or heptamethine-cyanines, merocyanines, hemicyanines, or hemioxonols, and supersensitizing mixtures may be used. Hardening, setting, or stabilizing agents may be added. In an example, to three batches of a gelatino-silver bromiodide emulsion are added (a) sodium thiocyanate, (b) sodium thiocyanate, ammonium chloropalladate, and ascorbic acid (reducing agent), and (c) sodium thiocyanate and larger quantities of ammonium chloropalladate and ascorbic acid. Details of speed, gamma, and' fog values for a specified developer are given. The use of osmium compounds is referred to. Specifications 450,958, 479,970, 515,145, and 517,769 are referred to.

Abstract: 404,999. Vulcanizing tyres. MACBETH, C., 67, Norwich Union Chambers, Congreve Street, Birming- ham. June 25, 1932, No. 17972. [Class 70.] In a vulcanizing-press comprising a horizontal lower member, and hinged upper members, the opening, closing, and locking means comprise a power-operated toggle mechanism formed of main links connected to the top mould member by overhead links, and a power cylinder between this mould member, and the overhead link. At the back of a lower mould member C is a pedestal D to which are hinged intermediate and upper moulds B, A. The toggle linkage consists of links i trunnioned to the member C at i<1>, and i<2> trunnioned to the member A at i<3>. Mounted on the link i<2> is a double-acting cylinder g, the piston-rod of which is pivoted at g<2> on the front of the mould A. To open the mould, power is admitted to the back of the cylinder g, and the links swing from the closed position, Fig. 1, to that shown in Fig. 3. The swinging of the link i causes a cam i<4> bearing on a roller b<4> to separate the mould member B from C, while a cam surface j prevents the members B and A from sticking together. At the same time, a cam k operated through links k<1>, k<2> raises the hinge k<4> of the member B, and also, acting through links k<6>, k<5>, that of A, so that the initial open and final closing movements are parallel. When the hinges have reached their maximum lift, continued operation swings the member A into the position shown in Fig. 3. To raise the intermediate member B, a separate cylinder h operates a depending lever extension of the member. The apparatus may be locked when closed by a catch p controlled by a cylinder p<2> communicating with the interior of the tyre, so that the catch cannot be released while there is pressure in the tyre. In a modification a single mould is described. For small work, parallel opening and closing it not necessary ; the cam operated hinges may then be dispensed with.

Filed: 1957-06-11
Abstract: 894,252. Cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 26, 1958 [June 11, 1957], No. 18332/57. Class 40(7). [Also in Group XL(b)] Apparatus for generating electrical representations of characters comprises a cathode ray tube to which is presented an array of patterns respectively representing variations of one co-ordinate of different characters expressed as a function of a parameter, means for deflecting the beam of the tube to select a desired one of said patterns, means for causing the beam to follow the outline of the selected pattern whereby to generate a waveform corresponding to the respective function and means for simultaneously generating another electrical waveform representing a variation of another co-ordinate of the selected character expressed as a function of said parameter. In Fig. 1 an array 3 of patterns representing x-co-ordinates of various characters are presented to a cathode ray tube 1 of a first curve follower and function generator and an array 4 of patterns representing yco-ordinates of the same characters are presented to a cathode ray tube 2 of a second curve follower and function generator. A shift circuit 14 causes the beams in the tubes 1 and 2 to select the patterns corresponding to any desired character which are scanned by the beams under the influence of a sawtooth waveform generator 11. The light outputs from the tubes 1 and 2 are detected by respective photo-cells 5, 6 connected to amplifiers 7, 8 which in turn are coupled to the deflecting systems 9, 10 of the tubes 1, 2. The beams are focused to spots and the arrangement is such that the spots are caused to follow along the outline of the patterns whereby signals representing the x-coordinates and y-co-ordinates of the respective patterns appear at the outputs of the photocells 5, 6. These signals are fed to respective x-deflecting plates and y-deflecting plates of a third cathode-ray tube 15 which thereby reproduces the selected character. The position at which the character is reproduced on the screen of the cathode ray tube 15 is controlled by shift circuits 16, 17. The waveform generator comprising the tube 2 may be replaced by a simple waveform generator the output of which is unchanged for a number of characters.

Title: Improvements in the manufacture of laminated springs
IPC: C21D9/02
Filed: 1920-07-03
Abstract: 170,061. Sanders, T. H. July 3, 1920. Angular bending and curving.-Plant for the continuous manufacture of laminated spring plates and other metal articles requiring similar treatment comprises means for automatically transferring the plates &c. through heating, bending, quenching, and tempering operations. Blanks from a stack 12, Fig.l, are pushed one at a time on to slide-rails 15 in a hardening furnace 14 by a spring-returned ram 10, the charging of one causing the discharge of another down slide rails 16 on to rotatable arms 18, 19 which transfer each plate to the forming machine, which may be of the type described in Specification 159,392. The movements of the ram 10 and of the transferrer arms 18, 19 are controlled from a timing shaft 4 which operates by means of contacts 5, 6 a valve 7 supplying steam or other fluid under pressure to the cylinder 9, which at the end of the stroke of the ram 10 exhausts into a cylinder 21 which operates the transferrer arms. The movement of these arms operates through a lever 27, a twoway valve 28 supplying steam alternately to a cylinder 29 operating the bending dies and to an ejector 33 or a similar device for controlling the level of the quenching liquid in the tank 30. Each plate is delivered by the transferrer arms on to the bottom die 26 of the forming machine, the top die then being forced down by the steam admitted to the cylinder 29, and to prevent distortion the plate is quenched while still between the dies. On steam being cut off from the cylinder 21, the transferrer arms are returned by springs, and in this movement operate the valve 28 so as to cut off steam to the cylinder 29, whereupon the top die 25 is raised by springs or counterweights so as to release the bent and quenched plate. At the same time steam is admitted to the ejector 33, which withdraws the quenching fluid from the tank 30 to the tank 32. The next plate delivered by the transferrer arms displaces the formed plate on to slide-rails 34, which deliver it to a conveyer 35 passing through a tempering furnace 36. The apparatus may be modified for the production of articles other than spring plates by the substitution of any known form of press in place of the spring-forming machine or by the elimination of the quenching tank or of the tempering furnace when tempering is not required.
