Title: Improvements in or relating to multiple stage vulcanising presses
IPC: B29D30/06
Filed: 1955-11-10
Abstract: 799,884. Vulcanizing presses. GUHR, K., and HERBERT, A., [trading as HERBERT MASCHINENFABRIK, L.]. Nov. 10, 1955 [Dec. 8, 1954], No. 32236/55. Class 87(2). A multiple stage vulcanizing press with a stationary mould carrier 3 and a mould carrier 7 movable between a closed position in which it is parallel to the carrier 3 and an open position in which it is removed from and inclined to the carrier 3 has at least one more mould carrier 17 between the carriers 3 and 7 which, as the carrier 7 is moved into the closed position, is brought to a position parallel to the other two carriers. The mould carrier 17 is controlled by the drive means for the carrier 7 and both are guided by rollers 8, 9 in guides 5, 6 in the machine frame. The invention is characterized by the feature that the travel of the carrier 17 and of any additional intermediate carriers is that fraction of the travel of the carrier 7 which is determined by the formula o/n + 1, where n is the number of intermediate carriers and o is their ordinal or positional number as calculated from the carrier 3. Two pairs of toggle links 10, 11 between the walls 1 and 2 of the machine frame, with the lower links pivoted on a shaft 12, are operated by a motor 15 through a draw member 14 to move the mould carrier 7 from the open position, Fig. 1, to the closed position when the toggles are straightened. The intermediate mould carrier 17 is operated from the toggle links 11 through lifting rods 22, which are slotted at 23 to embrace pins 20, on the mould carrier, supported by transverse pins 24 which can be inserted at various heights in rows of holes 25. The pins 20 carry rollers 21 which are guided by bars 18, 19. Directly beneath the rollers 21 is a pair of rollers 30 which can also run in the guideway between the bars 18, 19, and which, in the open position, rest against the lower end of the bar 19 where it is curved at 26. The bar 19 can be adjusted in position and an indication given by a pointer 28 associated with a scale 29 on the wall 1. The upper mould carrier 3 can be adjusted upwards or downwards by a cam device 4. In the open position the mould carriers 7 and 17 are both tilted outwards for ease of access. The travel of intermediate mould carriers is dependent on the pivotal position along the links 11 of the ends of their lifting rods, e.g., with two intermediate mould carriers the upper moves through one-third of the distance and the lower through two-thirds. The lower mould half 33 is supported from the mould carrier 7 through cup springs 32, Fig. 3, which are adjustable so that in the last part of the closing movement the springs are flattened and the mould held closed by their pressure, to compensate for the unyielding nature of the drive.

Title: Improvements in or relating to pressure vessels
IPC: F16J13/06
Filed: 1957-10-16
Abstract: 844,648. Covers for resisting fluid pressure. JENKINS & CO. Ltd., R., and OLDFIELD, G. H. Oct. 16, 1958 [Oct. 16, 1957], No. 32351/57. Class 123(1) The cover 10 of a cylindrical pressure vessel 9 is held thereon by a channel-section clamping ring 11 which is mounted rotatably on a continuous flange of a member 12 welded around the vessel rim and has its outer flange 19 castellated to provide tongues adapted to pass through and, on rotation of the ring, engage behind similar tongues 15 on a flange of a member 14 welded to the cover rim. The vessel is sealed by a flexible member 16 disposed between the members 12, 14. To prevent the cover being opened before its internal pressure is fully vented two safety devices which are operated in succession are provided. The first (not shown) consists of a locking catch which prevents the clamping ring from rotating and which is only releasable by a lever actuating a venting cock. The second device, which forms the subject of the invention, consists of an axially movable locking 'bar 21 slidably mounted in a housing 22 secured to the clamping ring 11. The bar 21 is urged inwardly by a spring 23 and at its inner end has an extension 24 which lies a short distance behind the flange member 14 when the cover is sealed. When the first safety device has been operated and the ring 11 turned to release the cover, any residual pressure in the vessel moves the cover outwardly against the stop 24 as shown in Fig. 3, the pressure being released as the seal is broken. The bar 21 may then be lifted by its handle 29 and is held clear by a spring-loaded latch 31 whilst the cover 10 is opened completely. When the cover is replaced and the clamping ring turned to its locked position an arm 35 on the cover trips the latch and the spring 23 returns the bar 21 to its operative position. Three or more spaced locking bars are usually provided. In a modification, the bars are withdrawn by solenoids energised simultaneously. Specifications 682,779 and 725,825 are referred to.

Title: Method of producing copies from pictures on multi colour screen films
IPC: G03C7/04
Filed: 1933-11-21
Abstract: 417,738. Colour photography. SAMUELSSON, J. E. S., 69, Birgerjarlsgatan, Stockholm. Nov. 21, 1933, No. 32454. Convention date, Nov. 21, 1932. [Class 98 (ii).] Multicolour screen pictures are obtained by copying from films provided with relatively large colour filter grains on to films having colour filter grains of considerably smaller size, e.g. one-half to one-tenth. For films, the screen may be formed by applying the grains, in the form of a powder, to the moistened film surface, removing excess by brushes, blowing &c., heating and flattening by passing between rollers; a light-sensitive layer is then applied. For glass plates, the screen is first formed upon a paper or other flexible support and then transferred to the glass. The average grain size for exposure material may be 0À02 mm. and for copy material 0À01-0À002 mm. Copying may be by contact or projection.

Title: Improvements in or relating to substituted benzofuranols and the manufacture thereof
IPC: C07D307/80
Filed: 1965-07-29
Abstract: Novel benzofuranols of the general formula <FORM:1120081/C2/1> where R1 is H, C1- 6 alkyl or phenyl, and R2 is C1- 6 alkyl or phenyl, are prepared either (a) by reacting an acetaldehyde diacylate of the general formula <FORM:1120081/C2/2> where 'Acyl' is the acyl radical of a hydrocarbon carboxylic acid with an alkanol and an alkali metal alkoxide or hydroxide, (b) by reacting a substituted benzofuranol of the general formula <FORM:1120081/C2/3> where R3 and R4 are C1- 6 alkyl, phenyl, C1- 6 alkylphenyl, C1- 6 alkoxyphenyl or halophenyl, provided that R3 and R4 are not simultaneously selected from phenyl and substituted phenyl, or R3 and R4 taken together with the nitrogen atom constitute a saturated heterocyclic amino radical, with an alkanol and heating in the presence of a strong mineral acid, or (c) by reacting the above amino-benzofuranol with a quaternizing agent in the presence of an alkanol.  The 2 - amino - 2,3 - dihydro - 3 - substituted - 5-benzofuranol starting materials are prepared by condensing a (1-alkenyl) amine of the formula R1R2C = CH-NR3R4 with p-benzoquinone, advantageously in the presence of an inert solvent and under substantially anhydrous conditions.  Pharmaceutical compositions comprise, as the active ingredient, a benzofuranol of the first general formula above together with a pharmaceutically acceptable carrier.  The compositions are useful as sedatives, central nervous depressants and antioxidants.
Patent GB-806465-A (GB)
Title: Method of and arrangement for aligning record carriers with an adjustable analysing device
IPC: G06K7/015
Filed: 1956-10-25
Abstract: 806,465. Photo-electric control. BASSLER, F. Oct. 25, 1956, No. 32528/56. Class 40 (3). In a machine for sorting articles by analysing the marks on record carriers, the adjustable analysing device is aligned with the record carrier by means of a photo-cell guiding arrangement. In Fig. 2, the record carrier 2 on the conveyer belt 9 has an edge marking 17 which is detected by the photo-cell shown in doublehatched lines in the battery 10, the analysing device 12 thus being moved to the position shown in full lines; if the record carrier is in a different position with the edge marking at 171 the single-hatched photo-cell responds and guides the analysing device to the position 121. In the sorting-machine of Fig. 1, a thin record carrier 2 is transferred from the magazine 1 to the plate 4. A system for rejecting carriers when two are superimposed or when the carrier is incorrectly positioned on the plate 4 consists of a light source 5 and photo-cells 6, 58 positioned opposite a hole 30 in the plate 4, the incorrectly positioned or superimposed carriers being detected by the photo-cells which actuate a flap 7 to transfer the carriers to the compartment 31. A correctly positioned record carrier is allowed to pass on to the conveyer belt 9 where it is illuminated from light sources 11 and the photo-cells 10 then detect the edge marking 17 and guide the analysing device 12 into alignment with it by means of a motor 26 and transmission gearing 14, 15; according to the result of the analysis, one of the flaps 33- 37 is actuated to transfer the carrier into the appropriate compartment. The analysing device may operate photo-electrically or mechanically. In a modification the optical device 12 and analysing photo-cells 13 are fixed, the device being adjusted by means of mirrors or prisms operated by photo-cells. For sorting parcels 50, Fig. 4, of variable shape and size, the optical device 12 must also be adjusted to the correct spaced relationship according to its focal length. The height of the optical device 12 is adjusted approximately by means of a feeler 54, and the fine adjustment is then carried out by the control photo-cell device 10 (not shown).

Filed: 1934-11-12
Abstract: 443,612. Centrifugal machines. WRIGHT, F. H., 1, Golders Green Crescent, Golders Green, and LEWIS; E. W., 320, Euston Road, both in London. Nov. 12, 1934, No. 32581. [Class 23] To enable vegetables to be washed and dried in a scraping or cleaning machine, a readily detachable cage is mounted on the rotary shaft. A scraping machine of the kind described in Specification 378,971, [Group VI], has a shaft 8 supporting a hub 13 to which is bolted a saucer shaped disc, as shown in dotted lines, and which also supports scraper blades to sweep the space 14 at the bottom of the container 1. The upper surface of the disc and the inner surface of the container are abrasive surfaces so that vegetables are scraped during rotation of the disc, and the scrapings are washed out by water supplied through the connection 7. The vegetables can be removed through the door space 18. Helical splines 12 of large pitch on the shaft 8 engage in grooves in the hub 13 so that this latter can easily be removed with the disc and scrapers. These parts are replaced by a similar hub carrying a spider 16 having four arms with their ends upturned to support a ring enclosing the basket 17. The vegetables are placed in the basket and washing water is supplied while the machine rotates. When the washing is complete, the supply of water is stopped and the cage is rotated at the highest speed permitted by the machine for drying purposes. A fan may be attached beneath the hub to cause air to pass downwards through the basket and upwards between the basket and the casing.

Title: Improvements in or relating to electric circuit-breakers of the gas-blast type
IPC: H01H33/90
Filed: 1939-12-21
Abstract: 537,482. Gas-blast switches. REYROLLE & CO., Ltd., COATES, F., and ALLAN, A. Dec. 21, 1939, No. 32674. Drawings to Specification. [Class 38 (v)] In a gas-blast switch of the kind in which a de-ionizing blast is forced under pressure through the arc by the heating effect of a second are in series with the main arc, gas is fed under pressure to the series arc by means of a piston orlike member which is either carried by one of the movable contacts or otherwise operated during the opening movement. The invention enables low breaking current arcs to be successfully put out as, instead of the low heat of the series arc acting on the pre-existing volume of gas in its enclosure a continuous stream of gas is supplied to the enclosure to be heated while the arc lasts and thus a relatively large blast is obtained. The invention is illustrated in its application to certain of the constructions shown in Specification 516,238, other features of which are also applicable to the present invention.

[Also in Division B8] Multi-layer blanks for bags, in which at least one layer is smaller than the others, are cut from a continuous web, Fig. 2, made by combining two or more webs 30, 21, of which the web 21 is narrower than the web 30 and has previously had excisions 47 cut in it to define part of the smaller layer. In the embodiments, the blanks are made from a foam layer 21 covered on one or both faces by paper layers 30, 31. In the blank of Fig. 2 foam free tabs 40, 41 are provided by the differences in width between the webs 21 and 30, 31 and foam free tabs 42-46 are produced by I-shaped excisions 47, the shaded area being cut out of the combined web when the blanks are cut out. Similarly the blank of Fig. 7 (not shown) is produced from the web of Fig. 6 (not shown), the transverse excisions (52, 53 and 55) in the foam web 21 producing foam free tabs (54) and (56). Foam free tabs (62-64) in the blank of Fig. 10 (not shown) are produced by making U-shaped excisions in the web 21. Similarly rectangular excisions in the web 21 produce foam free tabs (73, 74) for the blank of Fig. 11 (not shown). In this case the blank is erected into a box of which one wall (70), Fig. 12 (not shown), is made of cardboard. The above excisions are made in the foam layer 21 by a stamping or cutting device (22), Fig. 1 (not shown), compensating device (23) allowing the continuous feed of this web through the rest of the apparatus while the web moves intermittently through the device 22. Adhesived webs 30, 31 are then applied to the excized web 21 by guide rollers (24, 25), the combined web being pressed together by the pressing device (32). Finally blanks are stamped out of the composite web at (33). It may be necessary to provide a further compensating device between the stations (32, 33). If the web 21 already has the necessary excisions, the stamping and compensating devices (22, 23) may be omitted. Globular paper or similar substance producing a padding effect may be used instead of the foam web.
