Title: Improvements relating to apparatus for cutting down the surfaces of cylindrical stereotype printing plates
IPC: B41D5/00
Filed: 1959-11-20
Abstract: 873,101. Printing surfaces. FAUGLI, P. R., FAUGLI, I. O., and HEGSVOLD, O., [trading as FAUGLI & HEGSVOLD]. Nov. 20, 1959 [Nov. 27, 1958], No. 39492/59. Class 100(2) Apparatus for controlling a tool for cutting down parts of the surface of a cylindrical stereotype printing plate includes a drum of non- magnetic material rotatably mounted parallel to the axis of rotation of two or more plates mounted on a rotatable cylinder, the drum being at least as long as the plates and covered with a layer of magnetic material, means movable over the magnetic material to magnetise parts of it corresponding to the raised parts of the plate surface and a scanning head movable over the drum synchronously with the axial movement of the tool and, when passing the magnetised parts, energising an electromagnet to move the tool to an inoperative position. The drum 9 is helically wound with magnetic tape and the magnetising means 15 is controlled by sensing arms 13 which are manually moved against parts of the plate not to be cut down. The scanning head 12 controls an electromagnet 8 which controls the cutting tool 4 rotated by a motor 5 and moved axially by a lead screw 7. A permanent magnet 17 erases the magnetic pattern after use.

Title: Closure device and method for its installation
IPC: B29C61/10
Filed: 1975-09-26
Abstract: 1529352 Strip fastenings RAYCHEM CORP 26 Sept 1975 [27 Sept 1974 11 Aug 1975] 39515/75 Heading E2S [Also in Divisions B5 and H2] A closure assembly comprises a sheet 10 having two opposite edge regions 12, 14 which are brought into abutting relation with each other and a fastening device 24 which is positioned over the regions 12, 14 which by a change in shape caused by heat recovery either of the regions 12, 14 or of the fastening device 24 or both becomes a tight fit. In one embodiment, Figs. 1, 3 and 5, the sheet 10 is of heat-recoverable material, i.e. dimensionally heat-unstable material, and the regions 12, 14 comprise wedge-shape ridges 16, 18 and flat surfaces 20, 22 which are brought into abutment. The device 24 has walls 26, 28 extending from an apex 30 and which have depending therefrom legs 32, 34 terminating in flanges 36, 38. When the device 24 is placed over the bead formed by the ridges 16, 18, the legs 32, 34 may be crimped inwardly. Fig. 4 (not shown), by rollers 50, 52, Figs. I and 5. An adhesive or sealant may be used between the surfaces 20, 22 and between the member 10 and a substrate, e.g. a cable splice, to which it is applied to form a leak-proof seal. Heat is applied to the member 10 and to any heat-activatable adhesive or sealant present. The member 10 shrinks and forms a tight fit with the device 24. In a modification (not shown), the device 24 is preformed to conform to the ridges 16, 18 and is slid into place over these ridges and, if desired, further crimped. In a further modification, Fig. 6, longitudinal channels 54, 56 are provided in the surfaces 20, 22 and a rod (not shown) may be positioned in the cavity defined by the channels. Additionally, or alternatively, the surfaces 20, 22 are serrated to prevent longitudinal movement of one edge relative to the other. In other embodiments, (a) the ridges 58, 60, Fig 8, do not closely conform to the inner shape of the retaining device 62 but become thicker upon heating of the material of the member 10, and (b) no ridges are formed along edges 64, 66, Fig. 10, of the member 10 but, on heating of the member 10, these edges thicken to form ridges, the edges 64, 66 preferably being heated prior to heating of the main member 10 by prior heating of the retaining device. In a still further embodiment, Fig 12, the retaining device 72 is cylindrical and the bead formed by closure member ridges 74, 76 is smaller than the space enclosed by the device 72. On heat recovery, the bead may completely fill the cylndrical cavity, Fig. 13 (not shown). The invention is applicable to form a closure from a plurality of heat recoverable sheets with adjacent edges held by retaining devices, Fig. 7 (not shown).

Title: Improvements in or relating to the production of mirror glass
IPC: C03C17/10
Filed: 1929-12-27
Abstract: 345,676. Making mirror glass. PILKINGTON BROS., Ltd., 631, Tower Building, Water Street, Liverpool, WALDRON, F. B., Norwood, Eccleston Park, Prescot, and HARRISON, A., The Hollies, Holt Hill Lane, Whiston, both in Lancashire. Dec. 27, 1929, No. 39582. [Class 93.] Relates to apparatus enabling the processes of silvering and coppering in the production of mirror glass to be effected automatically and continuously without the necessity of handling by the operator; in addition, the operations of painting and drying may also be effected automatically and, if desired, continuously with the silvering and coppering. The glass is delivered by a conveyer 1 to the rollers 2 which carry it beneath water sprays 3 and pass it to a cloth band conveyer 7 passing over a heated table 8. The glass is covered by a silvering- solution and the table is of such a length that a sufficient thickness of silver is deposited before the end of the table is reached. The glass is then passed to a band 10 of copper net, chain or thin perforated sheet, or copper plates flexibly joined. The band is depressed, by passing under rollers 12 engaging its edges, into a coppering-solution, the band acting as the cathode, and plates 24 of copper forming the anode. The glass passes to a roller conveyer 13 whereon it is washed by water from sprays 14, and to a slat conveyer 15 which conveys it through a drying-chamber 16, a chamber 17 wherein shellac is sprayed on by sprays 18 movable across the chamber on rails 19, a chamber 20 wherein paint is sprayed from a traversing air brush 21, and through a drying-chamber 22 through which heated air is blown.

An axially split plug has a tubular portion 2 with a bore 6 and projections 17 extending from its periphery, the divided portion 4, 5 of the plug having consecutive sections 7-14 of polygonal cross-section, each section being angularly displaced in relation to the adjoining sections so that the corners 15 of one section project beyond the flats 16 of an adjoining section. When a bolt &c. is mounted in the plug the shanks 4, 5 are forced apart and the projections 17 bite into the hole. The corners 20 in a plane perpendicular to the plane of the slit 3 have flat faces 21 and the ends of the shanks are connected by a web 22 to prevent excessive separation of the shanks prior to inserting the plug in its hole. Projections 23 reduce the cross-section of the bore and the plug is made of a flexible plastics material. In modifications, barb-like projections are formed on the portion 2.

The esters may be prepared by reacting an acid halide of the formula CH3.O.CO(CH2)nCO.X with a compound of the formula MO.C6H4.R where X is a halogen atom preferably chlorine, M is an alkali metal atom or a hydrogen atom, R is a phenyl or phenoxy group preferably in the ortho or meta positions and n = 1-5, the ester being recovered by distillation.  Esters claimed per se are methyl o-phenylphenyl succinate, methyl m-phenoxyphenyl succinate, methyl m-phenoxyphenyl glutarate.  In an example methyl o-phenylphenyl succinate is obtained by treating the methyl half-ester of succinic acid with thionyl chloride and reacting the acid chloride obtained with the sodium salt of o-phenylphenol.  Other examples show the preparation of the other esters claimed per se.

A forging or stamping press has a tup d connected to a piston d<SP>1</SP> actuated through pressure fluid trapped in cylinder chamber A by a smaller piston o which is also actuated by pressure fluid. The tup d is slidable along guide surfaces x and carries a die OG co-operating with a die UG on the press bed. Retraction cylinders e are supplied continuously with compressed air through ports DM. The cylinder space A is supplied with oil from reservoir OB by pump g through pipe g<SP>1</SP> and non-return valve g<SP>11</SP>; excess oil is returned through port i and pipe g<SP>11</SP> and a by-pass valve V<SP>1</SP> permits continuous operation of the pump. Piston c has an enlarged head c<SP>1</SP> supplied with pressure fluid such as compressed air through inlet DM and control S. During descent of the piston c, the port i is closed whereby the trapped oil produces the working stroke of the tup. The control S may provide for part of the stroke of piston c to be produced by expansion. Means may be provided to prevent operation of the control S unless the piston c is fully in its upper position.
