Title: Improvements in plate cylinders for rotary printing presses
IPC: B41F27/10
Filed: 1934-05-16
Abstract: 426,687. Printing-surfaces. SWIFT, C. W., 12, Carrick Place, Mt. Eden, Auckland, New Zealand. May 16, 1934, No. 14826. Convention date, March 15. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 1, 1934] [Class 100 (ii)] In plate-cylinders for double-width printing- presses means are provided for enabling longitudinal and circumferential adjustment of the plates comprising centre margin ring means, inwardly movable against springs and disposed so that each portion adapted to engage a separate plate can move independently of other portions, divided inner dogs with compression springs between the two halves of the dogs, and means for locking the inner portions of the dogs to the cylinder. Instead of the usual fixed centre ring, the ring 3, Figs. 1 and 5, is split into halves 4, 5, which are pressed apart by springs 12, and slidably held in a groove 2 by an anchor plate 9. The ring-halves 4, 5 are divided into quadrants for separate adjustment, and the quadrants are staggered in the two halves to secure even running. In a three-dog cylinder the centre dog 15 is split longitudinally and circumferentially into quarters 15A, 15B, 15C, 15D, the quarters 15A, 15B and 15C, 15D, being slidably keyed together and the quarters 15A, 15C and 15B, 15D being spring-pressed apart. The quarters 15A, 15C are united by bars 25 to the unsplit dogs 14A, 14B, and the quarters 15B, 15D to the dogs 16A, 16B. A screw, (not shown), turned by a key locks the quarters 15C, 15D in adjusted position. The quarters 15A, 15D are adjusted by hanging rods 21A, 21B, formed from the normal adjusting rod split down the centre, prevented from rotating by a set-screw engaging a key way, and engaged by screws 29A, 29B, which also operate the split outer dogs 27A, 27B. When quarter-plates are to be used, middle-plate clamps 30A, 30B are secured to the cylinder by screws 34 passing through slots 33, the clamps 30A, 30B again being pressed apart by springs 38, but joined by links 39 to prevent too great separation. In an alternative construction of clamp, the rod 43, Fig. 8, passes through both dogs and has an oval portion 48 engaging keys 49 so that rotation of the rod forces out the keys and locks the dog 40 into position in its groove. The clamping arrangements are primarily intended for use in colour printing, when half and quarter plates are used and must be individually adjustable for register. This can be effected by starting from the dog-ring 4 at the centre of the cylinder and working outwards, and adjusting and clamping the plates one by one.

Title: Improvements in and relating to thienyl-substituted polysiloxanes
IPC: C08G77/00
Filed: 1950-06-14
Abstract: Polysiloxanes containing 2-thienyl and/or 3-thienyl substituents are made by hydrolysing one or more monothienyl halogeno- or alkoxy-silanes either alone or with one or more hydrocarbon-substituted halogeno-silanes.  The thienyl silanes used have the general formul  <FORM:0695462/IV (a)/1> and <FORM:0695462/IV (a)/2> wherein Z is a halogen atom or an alkoxy radical, such as ethoxy, propoxy, or butoxy, R1 is a monovalent hydrocarbon radical and n is 1 or 2.  The hydrocarbon-substituted silanes specified contain methyl, ethyl, propyl, isobutyl, hexyl, decyl, phenyl, diphenyl, naphthyl, benzyl, tolyl, xylyl, phenylethyl, cyclohexyl, cyclohexenyl, vinyl and allyl radicals.  The hydrocarbon radicals may contain halogen substituents, e.g. the fluorinated compositions described in Specification 659,439.  The hydrolysis may be effected in water, with or without solvents such as ether or those disclosed in Specification 585,627.  In examples: (1) 2-thienyl trichlorosilane was hydrolysed in a mixture of water and ether; (2) hydrolysis of methyl 2-thienyl dichlorosilane by dropping an ethereal solution thereof on to a slurry of water, ether and sodium carbonate, with subsequent separation of the ethereal layer, drying and removal of the ether, resulted in an oily liquid, whereas hydrolysis in an aqueous sodium bicarbonate solution with subsequent heating of the hydrolysate, gave a gum which, when mixed with titania and benzoyl peroxide and heated in a closed mould, gave a white flexible rubber; (3) tetramethyl di-(2-thienyl)-di-siloxane was made by hydrolysing a solution of dimethyl-2-thienylchlorosilane in ether with water; (4) 2-thienyltrichlorosilane with dimethyldichlorosilane, or methyltrichlorosilane, or both, (5) methyltrichlorosilane and methyl 2-thienyldichlorosilane, (6) methyltrichlorosilane, methyl 2 - thienyldichlorosilane and 2 - thienyltrichlorosilane, (7) 2-thienyltriethoxysilane, were hydrolysed in the usual manner, under acid or alkaline conditions.  The products may be used as hydraulic fluids, lubricants, coating compositions either per se or in the form of varnishes or solutions which can be used to impregnate and coat fibrous materials which in turn find use in insulating electrical conductors, and for impregnating and coating fibrous sheets such as asbestos, glass, cotton or paper which can be formed into laminated products.  Fillers such as asbestos, glass fibres, quartz powder and wood flour, may be incorporated into the compositions with subsequent moulding under heat and pressure.  The polysiloxanes or copolymers may be compounded with natural and synthetic rubbers, tars, asphalts, pitches, rosin, shellac, phenol-aldehyde resins, urea-aldehyde resins, modified and unmodified alkyds, vinyl resins, acrylic acid ester resins, cellulose acetate and cellulose ethers.  They may also be used as p  plasticizers for other organopolysiloxanes. Specification 695,461, [Group IV (b)], also is referred to.

Title: Improved device for decreasing yarn tension during unwinding
IPC: B65H57/22
Filed: 1963-04-16
Abstract: A yarn balloon controlling device 4 for use in the unwinding of thread or yarn F from a cop comprises two plates disposed substantially at right angles, the length and disposition of the plates being such that a multiple balloon is maintained throughout the unwinding process, in spite of changes is the withdrawal length of the yarn.  The plates are situated close to the location of a thread guide member 3, meet along a line of intersection situated along the axis of the cop, and are preferably provided with corrugated inner surfaces to intensify the disturbance effect on the ballooning yarn.  The device may be incorporated in an automatic winding machine and a pivotally mounted yarn feeler member is operable through transverse slots in the plates of the yarn balloon controlling device to detect the presence of yarn.  Actuation of the yarn feeler member is caused by a mechanism, which detects the absence or breakage of the yarn at a subsequent point in the machine. If the yarn is not present at the yarn balloon controlling device, e.g. due to completion of the unwinding of the cap rotary movement of the yarn feeler member continues to a point at which a switch is operated and automatic cop changing mechanism brought into operation thereby.

Filed: 1968-03-29
Abstract: 1,196,346. Digital electric computer. ING. C. OLIVETTI & C. S.p.A. 29 March, 1968 [1 April, 1967], No. 15335/68. Heading G4A. A stored programme electronic digital computer comprises means for the automatic execution of the stored programme and a device for reading individual cards each containing a sub-programme, and automatic addressing means responsive to the introduction of a single card into the reading device, such introduction being controlled by the operator, to control entry of the subprogramme in the internal store of the computer and its consequent execution. The computer is the same as that described in Specification 1,196,347, with the addition of a magnetic card reader. The capacity of each card is equal to the capacity of five registers although cards with a capacity of only two registers can be used when a card partialization key is pressed. This latter compels the register counter to commence at a register D so that only register D and E can receive data, the partialized cards serving to enter new data without destroying programmes stored in the earlier three registers. Fig. 7 shows a main programme recorded in places C2 to C86 of the instruction registers. Depression of the key SP then causes recording of a manually entered card into places C91 to C113. The main programme can be carried out as described in Specification 1,196,347, with inclusion of the subprogramme in places C91 to C113. The programme continues until STOP in place C63 is reached. This allows the operator to record a second subprogramme in places C91 to C120 and, by pressing the start key continue with the automatic processing.

Abstract: 222,174. Sykes, A. F. June 13, 1923. Multiple-diaphragm soundboaes; connecting toolarms to diaphragms. - Relates to means for damping the vibrations of a diaphragm, such as is used in phonographic or telephonic apparatus, in order to suppress or reduce resonant overtones. According to the invention, one or more damping plates are carried by or mechanically connected to the diaphragm, and vibrate therewith, a substance such as petroleum jelly, oil, or rubber being interposed between the plate or plates and the diaphragm. Figs. I, II, and III show the invention applied to gramophone sound. boxes. The stylus-bar e may be mechanically attached to both the diaphragm a and to the damping-plate b, Fig. I; or to the plate b only, Fig. II; or to the diaphragm only, Fig. III. The layer of viscous or resilient material is shown at d in each case. In the device shown in Fig. II, the vibrations of the stylus-bar are transmitted to the diaphragm through the damping-material d only. The plate b in Fig. III is annular, and may be connected to the diaphragm a through studs c. In another construction (not shown), the damping plate and the diaphragm are of the same size and are both attached to the stylus-bar, the space between them being filled with oil &c. and peripherally sealed. Fig. VII shows a corrugated phonograph diaphragm a of thin aluminium, having plates b', b<2> attached thereto, with intervening material such as grease or rubber solution. The application of the invention to various forms of telephone receivers and load-speakers is described, and is shown for example in Figs. V, VI, and IX. The damping plate b shown in Fig. V, on the side of the diaphragm a opposite to that of the magnet G, may be of iron. The devices shown in Figs. VI and IX are electrodynamic loud-speakers. The damping plate b in Fig. VI is adjustably attached to the diaphragm a on the side remote from the coil h and is grooved to prevent cavitation due to the inertia of the oil d, In the apparatus shown in Fig. IX. which is of the kind described in Specification 227,162, the conductor i is distributed over the surface of the diaphragm a.

Abstract: 982,380. Coiling textile sliver. WARNER & SWASEY CO. April 19, 1963 [June 19, 1962], No. 15514/63. Heading D1F.  Sliver is continuously delivered at constant speed into a container which is moved in a sidewise direction relative to a coiling head to form a first row of coiled sliver, whereupon the container is moved in a second direction perpendicular to the first and for a distance not exceeding the diameter of a coil of sliver and then in a third direction opposite to the first so as to form a second row of coiled sliver which may overlap the first row. In sliver handling mechanism 10, slivers S drawn through gill boxes 12,13, by front rollers 14,15, are deposited in coils or loops by coiler heads 16, 17, into containers T,T<SP>1</SP>,carried on a transfer table 20 which is traversed (in the direction of arrow 21 and in the reverse direction) and indexed forwards and backwards (in the direction of arrows 23 and 103) until the containers are filled with superposed layers of adjacent or overlapping rows of coils &c. of sliver. The traverse drive, Fig. 3, is derived from an endless chain 28 running continuously over sprockets 29, 291, and carrying a roller 36 engaging and sliding in a slot 38 in a member secured to table 20. At the extremities of the traverse motion, engagement of a cam face 61 of a cam 52 or 53 with one of a series of rollers 79 or 80 effects a single indexing forward movement of the table 20. As one layer of sliver approaches completion, engage. ment of a cam follower 98 with a fixed cam surface 100a slides a rod 96 from one positive position to another to cause an actuating portion 70 to engage convex cam portions 67 and pivot cams 52, 53, into a position whereat cam surfaces 62 thereafter engage rollers 79 or 80, to index backwardly the table 20. As the second layer of sliver approaches completion, engagement of a follower 99 with cam surface 101a pivots the cams 52, 53, into their starting position. The traverse and indexing movements of the table are guided by rollers engaging way surfaces on frame members.
