Title: Method and apparatus for moulding a curved flexible printing plate
IPC: B29C45/44
Filed: 1976-10-13
Abstract: 1503289 Releasing curved moulded printing plates TIMES MIRROR CO 13 Oct 1976 42489/76 Heading B5A A curved plastics printing plate 10, injection moulded between male and female dies 12 and 11 respectively, is removed from the matrix forming the moulding surface of the female die by first moving the ends of the plate inwardly away from the matrix (see Fig. 1B) and then moving the bent plate bodily away from the matrix (see Figure 1C). In this way all areas of the plate are removed from the matrix substantially radially and there is a minimum of disortion of the surface of the plate. The inner die comprises a central section 13 of wedge shape which co-operates with end sections 14, 15 each of which is provided with a bar 16 or 17 which co-operates with its end section to form an inwardly directed hook 10a or 10b on the ends of the plate. In use, the central section is withdrawn a first increment whilst the end sections are restrained from movement with the central section but slide inwardly relative to it to free the ends of the plate from the matrix. The central section is then withdrawn a second increment during which the end sections move with it to pull the plate fully away from the matrix. During a third increment of withdrawal of the central section the bars 16 and 17 are cammed away from the end sections to free the ends of the plate and during a fourth increment pins (see Fig. 10, not shown) carried by the end sections are actuated to push the hook outwardly free of the end sections. Since the apparatus is oriented with the axis of curvature of the matrix vertical, the freed plate drops from between the now fully opened dies.

Abstract: A moisture-curable siloxane having the formula <FORM:1089229/C3/1> wherein each R is a monovalent hydrocarbon (h.c.), halo-h.c. or cyanoalkyl radical, R1 is H or an alkyl or halo-alkyl radical of 1 to 4 C atoms, R11 is a saturated or unsaturated h.c. radical with or without halo-or cyano-substituents, and n is an integer such that the viscosity of the polymer is from 500 to 500,000 cps. at 25 DEG  C., is generally made by reacting an OH-terminated organopolysiloxane liquid with the product obtained by reacting a tetracycloxysilane with the desired alcohol, the product being mainly R11OSi(OOCR1)3 with varying amounts of (R11O)2Si(OOCR1)2 and unreacted Si(OOCR1)4. The reaction of the silane product and the siloxane is best effected at 95 DEG  to 100 DEG  C. under anhydrous conditions.  Dry fillers, e.g. silica (fume, precipitated or aerogel), diatomaceous earth, crushed quartz, TiO2, Fe2O3, ZnO, asbestos and fibrous glass, colouring agents, dielectric materials, e.g. graphite, and other additives, may be added.  Resinous siloxanes may be added either to improve adhesiveness or to decrease elasticity, and liquid siloxanes may be added as plasticizers. In a typical Example (1), MeOSi(OAc)3 was reacted with an OH-terminated siloxane liquid at 95-100 DEG  C. in a dry nitrogen atmosphere to yield a viscous material which formed a tack-free rubbery surface within 10 minutes after exposure to atmospheric conditions.  Uses.-In mould making, coating operations and for caulking.

Title: Improvements relating to the production of polyethylenes and catalyst therefor
Inventor: D ALELIO GAETANO FRANCIS
IPC: C08F10/00
Filed: 1959-12-15
Abstract: An ethylene polymerization catalyst is prepared by heating iron with titanium tetrachloride to a temperature between 130 DEG C. and the melting point of iron, to give a product comprising both metallic iron and a reaction product of iron and titanium tetrachloride.  The product may be rendered free from hydrocarbon-soluble metal chlorides, e.g. by washing with a hydrocarbon (e.g. benzene or toluene) capable of forming complexes with iron chloride or titanium tetrachloride, and then with a hydrocarbon (e.g. heptane) incapable of forming such complexes. The usual hydrocarbon solvents are used as polymerization media. The polymeric products may be solids which can be used to make mouldings, films, filaments, pipes, tubing and extruded articles, or liquids stated to be useful as intermediates, e.g. for alkylation or epoxidation and also as plasticizers for the solid polymers.  As an example of the latter use, a viscous oil of one example is mixed with 10 times its weight of the solid polymer of another example and the product is sheet-extruded.ALSO:An ethylene polymerization catalyst is prepared by heating iron with titanium tetrachloride to a temperature between 130 DEG C. and the melting point of iron, to give a product comprising both metallic iron and a reaction product of iron and titanium tetrachloride.

Abstract: 1279039 Alkali metal salts of hydroxybenzoic acid esters UENO SEIYAKU OYO KENKYUJO KK 7 Sept 1970 42837/70 Heading C2C An alkali metal salt of a p-hydroxybenzoic acid ester is prepared by reacting a p-hydroxybenzoic acid ester with an alkali metal phenoxide in the presence or absence of an inert organic solvent. When the inert solvent is employed it is preferable to use a solvent which dissolves the phenol produced in the reaction but does not dissolve the alkali metal salt of p-hydroxybenzoic acid ester. The process is particularly suitable for the preparation of the salts of formula wherein R is an alkyl group having up to 10 carbon atoms, an aryl group having 6-10 carbon atoms or an aralkyl group having 7-10 carbon atoms and M is an alkali metal atom.

Title: Improvements in or relating to apparatus for stacking articles
IPC: B65G57/00
Filed: 1962-11-21
Abstract: 1,021,022. Stacking articles on pallets. EMHART CORPORATION. Nov. 21, 1962 [Dec. 7, 1961], No. 44052/62. Heading B8C. Apparatus for stacking articles, e.g. bottles, on pallets comprises a conveyer, transfer means for moving a row of articles transversely from the conveyer on to a collecting plate, together with intermittent one-way drive means for moving the collecting plate in increments transversely beneath the conveyer simultaneously with the depositing of the articles thereon and drive means for retracting the collecting plate when the required number of rows has been positioned thereon so that the articles drop on to a pallet.  The transfer means comprises a pusher bar 14 which moves across the conveyer belt 10. The bottles B engage the arm of a counter unit 16 which operates, after a preset number of bottles has moved along the conveyer 10 in front of the pusher 14, to project a pivoted arm 26 into the path of the bottles. Each side of the collecting plate 12 is provided with a strip 58 having ratchet teeth which are engaged by a pawl 46 pivotally connected to the pusher bar 14 so that when the pusher bar advances to transfer a row of bottles to the plate 12, the plate moves forward an equal distance. When the pusher bar 14 retracts the pawls 46 move back over the ratchet teeth of the plate 12, these teeth being spaced a distance corresponding to the diameter of the bottles. When the pusher bar 14 is fully extended the pawls 46 are pivoted away from the teeth of the plate 12 so that the plate 12 may be retracted after the required number of rows has been positioned thereon. The belt 10 is stopped while the bottles are transferred to the plate 12. The rows of bottles are staggered by an end stop 30 which is extended when it engages the foremost bottle of every other row. A channel-shaped member 94 supports a vertical plate 96 and is biased by a weight 118 towards the conveyer 10 to hold the bottles in their erect positions. A pallet P is held immediately below the extended position of the collecting plate 12 by an elevator so that as the plate is retracted the bottles, retained by the extended pusher bar 14, drop on to the pallet. The elevator is then lowered a distance equal to or slightly greater than the height of the bottles. Photo-electric means 133 control the elevator descent. A chipboard separator may be placed over the bottles to provide platform support for the next layer. Finally the elevator operates a switch 134 to cause removal of the load. The extent of the incremental movement of the plate 12 may be adjusted by interchanging the strips 58.

A friction clutch may be provided between motor 1 and spindle 7 to absorb excessive torque. Each of the clutches 12, 13 comprises a body 14 rotatably mounted on spindle 7, and having rollers 16, carried in pockets 15 which taper in the circumferential direction, each of the rollers being biased towards the narrow section of its pocket by a spring and plunger 18, 19. A sleeve 27 is keyed for axial movement in housing 2, and carries two lugs 30 which engage in grooves 31 in clutch bodies 14, of either clutch 12 or clutch 13. Sleeve 27 is actuated by a spring 24 which is compressed by the leg 22 of a slidable switch 20, the latter also actuating a reversing contact 4 for the motor drive.
