Title: Improvements in bookbinding machines
IPC: B42B2/00
Filed: 1943-03-02
Abstract: 563,965. Bookbinding. FLOWER, D. J. N., HARRISON, T., and BROOKS, J. L. March 2, 1943, No. 3444. [Class 16] In a bookbinding-machine of the type in which tapes are passed through T-shaped slots made in the book and are then glued to the inside covers, the tapes are drawn through the slots by means which grip them against the trailing ends of the slotforming knives and subsequently release them. The book is held in a stationary clamp C, Fig. 10, and the stems of the T-slots are cut by saws 48. The heads of the slots are then formed by piercing-knives 62, both the saws and the knives being mounted on a horizontally sliding carriage D, which is operated by rack-mechanism from a capstan. Tape-reels 81 are mounted in a pivoted frame 78, and the tapes 82 depending therefrom, after passing through a spring friction-gate 84, are gripped against the rear ends of the knives by spring-pressed grippers 66. The tape-reels are first raised, so as to unwind a length of tape, which is cut off by oppositely moving knives 112, 113 mounted on the frame 78. The carriage D is then traversed, so as to form the T-slots and draw the tape through them. The tape-grippers 66 are arrested by a fixed stop to release the ends of the tapes. The book-clamp comprises an upper pair of jaws 35, 38 and a lower pair 25, 36, the adjustable jaws 25, 38 being operated by screws 26, 39 and worm-gearing turned by hand-wheels. The upper part of the clamp can turn about a pivot 34, so that it can be swung up, together with the clamped book, to give access to the tapes for glueing. The lower jaw 36 is pivoted to the upper jaw 35 and is normally supported by a fixed abutment 23. When the clamp is swung up, the jaw 36 tilts, as shown in Fig. 15, so as to expose the side of the book. The capstan, by which the machine is operated, is movable along its shaft, so as to engage with either of two clutch-members. One of these is connected with means for operating the tapecarrying frame and the severing-knives, and the other with means for operating the carriage that supports the saws and the piercing- knives. The machine may be operated by power.

Title: Die casting machine
IPC: G01P3/68
Filed: 1972-01-26
Abstract: 1338756 Pressure die casting machines IDRA-PRESSEN GmbH 26 Jan 1972 [3 Feb 1971] 3576/72 Heading B3F [Also in Division G1] In a cold chamber die casting machine, the speed of movement of the piston is measured by monitoring the movement of a polished facetted ring 19 on the screw cap 17 past a plurality of regularly spaced light transmitters and receivers. The screw cap or union 17, connects the rod 15, attached to the piston 13, to the firing piston-rod 16 which drives metal 12 into cavity 10 between movable and stationary mould halves 4, 3. Along the path of movement of ring 19 are two inclined linear arrays of light fibres held by strips 20, 21. One way conducts light from a common lamp 31 via lens 30 to the line of movement of reflective ring 19, which as it passes, completes the light path between one transmitting light fibre and the corresponding receiving fibre in the other array which lead light to a common photodiode. The effect is thus to produce a sequence of pulses which are recorded as marks on a uniformly moving chart recorder the density of the marks indicating the speed of the piston. In a modification, Figs. 7, 8 (not shown), arranged to indicate the occurrence of any piston recoil, the light fibres are associated in groups with three photodiodes, each controlling recording on the same chart but with different types of mark.

Title: Process for the Preparation of Acetic Aldehyde from Acetylene.
Filed: 1918-02-28
Abstract: 130,650. Compagnie des Produits Chimiques d'Alais et de la Camargue. Jan. 12,1917, [Convention date]. Acetaldehyde.-In the production of acetaldehyde by passing acetylene into acid solutions of mercury salts, the aldehyde is continuously removed from the liquid by applying a vacuum. Using the apparatus shown, acetylene is passed by a pipe B into the reaction liquid in a vessel A; the liquid passes by the pipe D to a receiver F in which a partial vacuum is maintained by a pump G; the vapour of aldehyde and steam pass off to the pump, while the liquid freed from aldehyde returns by a pipe H to the vessel A. The rise of the liquid in the pipe D may be assisted by a steam jacket K, by admitting air by a pipe L, or by other means. Specifications 29073/10, 16848/13, 17017/13, and 16957/14 are referred to.
Patent GB-852520-A (GB)
Title: Process for the manufacture of copolymers of vinyl ester and maleic acid
IPC: C08F218/04
Filed: 1957-02-01
Abstract: Mercuriferous copolymers are made by copolymerising a vinyl ester and maleic acid (or anhydride) in the presence of a mercury compound and, as catalyst, concentrated H2SO4 or other strong acid or a potent condensing agent, e.g. boron trifluoride etherate, boron fluoride hydrate or perchloric acid, the mercury compound being an oxide or a salt that is soluble in the reaction mixture.  The process may be effected simply by adding the mercury oxide and H2SO4 to a mixture of the vinyl ester, e.g. vinyl acetate or propionate, and maleic acid, the ester being used in stoichiometric excess over the acid, and stirring the mixture at room temperature for several hours to yield the copolymer as a white precipitate, which is then filtered and washed with the vinyl ester, further copolymer being precipitated from the washings.  The combined precipitates are dried to yield a light powder which is readily soluble in water. This solubility may be reduced by effecting the copolymerisation with an additional ethylenically unsaturated compound, e.g. styrene, vinyltoluene, acrylonitrile, an acrylate, allyl alcohol or butadiene.  The copolymerisation may also be effected with the addition of known crosslinking agents, e.g. vinyl crotonate, or vinyl succinate, and at temperatures above room temperature, e.g. at 40 DEG  to 60 DEG C. The polymers of reduced water-solubility are plastic when warm and soluble e.g. in ketones, dimethylformamide and diethyl-sulphoxide, and their solubility in water is enhanced by the addition of an alkali, ammonia, ammonium compound or an amine, e.g. ethylamine.  The mercury can be dissolved out of the copolymer by means of a strong acid, e.g. dilute H2SO4 or HCl.  In the examples the copolymers are made in the above manner from (1) vinyl acetate, maleic acid and HgO in the presence of conc. H2SO4; (2, 4) as in (1) but with the addition of styrene and mercuric acetate instead of HgO; (3) as in (2) except maleic anhydride is used in place of the acid; (5) as in (4) but with the addition of vinyl crotonate; (6) as in (1) but with the addition of acrylonitrile; (7) as in (6) but with the addition of divinyl succinate.  Uses. the mercuriferous polymers can be used as bactericides; the polymers free from Hg can be used for moulding compositions, for lacquer making and for making further copolymers.

Button-attaching machines.-The button-holding clamp is mounted on a vertical shaft 13 supported in a bracket 12 independently of the clothplate 10. The work-plate member 16 of the clamp is rigidly secured to the shaft 13 and the upper member is carried by a bracket pivoted to the upper end of the shaft so that the upper member can be raised by a connection 51 with the presser-foot lifter. The button-gripping members 37, Fig. 3, are pivoted to a plate 20 of the upper clamp member and are urged together in a known way by a slotted plate 41 and a spring 46. The clamp is automatically oscillated by means of a cam, link, and a lever-arm 56 on the shaft 13. The lever has a curved slot to receive a pin on the end of the link and the pin is moved in the slot to vary the movement of the clamp by means of a slide 57 on the lever-arm which embraces the pin and can be moved along the lever by a screw 58. In attaching four-hole buttons, after the stitching in one pair of holes is completed, the upper member of the clamp is moved longitudinally by hand to position the button for the stitching in the second pair of holes. For this purpose, the plate 20 of the upper clamp member is slidably supported on the bracket pivoted to the upper end of the shaft 13 and is held in place by a plate 21 and screws 22. A hand-lever 24 is pivoted on the fixed plate 21 at 25 and engages a pin 27 on the plate 20. Pins 28 and a wedge-shaped piece 29 on the lever 24 determines the motion of the lever.
