Title: Carrier current signalling systems
IPC: H04L25/08
Filed: 1929-11-20
Abstract: 343,516. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- {Western Electric Co., Inc. ; 195, Broadway, New York, U.S.A.) Nov. 20, 1929, No. 35474. [Class 40 (v).] A current, tending to annul the effect of extraneous electric disturbances, is impressed on a translating device 7 in a carrier-current telegraph receiver, and the effect of the current is automatically modified according to whether the disturbances occur during marking or spacing periods. The armature 11 of the receiving relay 7, in the output of a receiving channel A, is normally held on its spacing contact S by current from a battery 9 through a biasing-winding 8. A marking signal causes sufficient current to flow through the winding 6 in the plate circuit of a rectifying valve 5 to overcome the effect of the biasing current and move the armature to its marking contact. Current then flows from batteries 12, 35 through a relay 16, which reverses, by its armatures 19, 21, the direction in which current from a rectifying valve 20 in an auxiliary channel B flows through a winding 23 in the receiving relay 7. The coil 23 is wound so that current from the valve 20 due to the receipt of an atmospheric tends to maintain the armature 11 on the contact on which it is resting at that moment. Similar reversing relays 29 and coils 34 in receiving relays 28 are provided in the other receiving channels C, D, E. The common neutralizing-rectifier 20 may be replaced by a separate rectifier for each receiving-relay. According to modifications: the reversing operation is performed by a single armature (Fig. 2, not shown), which may constitute an additional armature on the receiving-relay (Fig. 3, not shown), and two detectors are connected respectively to oppositely wound, neutralizing coils in the receiving relay, or a single detector may be used (Fig. 4, not shown) ; two auxiliary channels are provided, to one of which carrier current is continuously transmitted (Fig. 5, not shown) ; superheterodyne amplification is used (Fig. 6, not shown) ; the armatures of the receiving-relays are locked in position mechanically instead of electromagnetically when atmospherics are received by one (Fig. 7, not shown) or two auxiliary channels (Fig. 8, not shown) ; the auxiliary channel is connected to the operating winding of the receiving relay during marking and to the spacing winding during spacing (Fig. 9, not shown) ; the auxiliary channel comprises an auxiliary detector in parallel with the ordinary detector after a common amplifier (Fig. 10, not shown).

Patent GB-508021-A (GB)
Title: Improvements relating to the manufacture of hollow glassware
IPC: C03B9/18
Filed: 1937-12-22
Abstract: 508,021. Making hollow glassware. BRIDGES, E. G. Dec. 22, 1937, No. 35507. Convention date, Nov. 30. [Class 56] Relates to the manufacture of hollow glassware by a machine of the double table type described in Specifications 160,366, 365,245, and 386,012. The invention consists in subjecting each parison, after it has been formed and while confined in the parison mould, to air pressure after the normal cotmterblow in order to set the glass. The mould is opened earlier than usual to allow the parison to reheat, and after the parison is transferred to the finishing mould the final blowing is continued at several successive positions where the moulds are stopped. The parison mould table 11 and the finishing mould table 13 may have an equal number of moulds on each, or more finishing moulds may be used, and the tables may be rotated step by step by a pneumatic motor 40, or by a Geneva gear of the kind described in Specification 508,056, so that the moulds are presented to a number of operating stations. At station A, a parison mould 10 is inverted and is charged with molten glass through its open end, the mouth portion being closed by a mandrel 15 raised and lowered by a pneumatic motor 16. After charging, the open end of the' mould is covered by a blowhead 17 through which air is blown to compact the glass. The mould then moves to station B where the glass is counterblown to form a parison. The mould moves next to station C where the parison is again subjected to air pressure to cool and set the glass. Reinversion of the mould takes place while moving to station D, and at this station the mould is opened to allow the chilled skin of the parison to reheat. This reheating takes place preferably at three successive stations D, E, F during a time equal to the parison - forming period, but it may be accelerated by applying the flame of a gas burner. In order to straighten the parison and to prevent @indue elongation during reheating, a paddle or former 30 having an inclined upper surface is brought into contact with the lower end of the parison at station D. Transfer of the parison to a finishing mould 12 takes place between stations D and E, and blowing of the parison to its final form commenced at station G and continues at stations H and I for a period preferably equal to or greater than the parison-forming and reheating periods. The finished bottle may be removed by a take-out device such as that described in Specification 365,245. In a modified construction, the parison mould is reinverted between stations A and B, and the parison is counterblown while it is neck upwards. This construction allows a longer time for the parison to reheat..

Title: A method of manufacturing a backer for use the the manufacture of leather substitutes
IPC: D06N3/00
Filed: 1969-07-15
Abstract: 1,273,386. Laminates. STATNI VYZKUMNY USTAV KOZEDELNY. 15 July, 1969 [16 Aug., 1968], No. 35525/69. Heading B5N. [Also in Division D2] A method of making a backer for use in the production of leather substitutes comprises applying a layer of swollen, untanned, collagencontaining fibrous material to one or both sides of a textile screen, treating the structure with a salt (e.g. Na Cl) to deswell the collagen fibres, pressing the structure, e.g. stepwise, needle punching the structure e.g. while it is still wet, tanning it, and applying a second textile screen to the exposed face of the collagen layer. Alternatively, before deswelling of the fibres, a natural or synthetic fibrous web may be applied to one or both faces of the structure. The textile screen, which may be of woven, knitted or non-woven fabric, and web may be of polyamide, polypropylene, polyester, polyacrylonitrile, staple regenerated cellulose, cotton, wool or flax fibres or mixtures of these. The collagen fibre material is prepared from split hides or waste from the machine treatment of hides, may be mixed with textile fibres or ground shavings of chrome-tanned leather, and may contain a non-ionic or cation-active fatliquoring agent or a binder such as latex, polyacrylate, polyisocyanate or their monomers. The salt may be added as a saturated solution or in finely powdered form. The tanning may be with a salt of Cr, A1 or Zr, or with formaldehyde and the backer is then preferably dried. After drying, the backer may be impregnated with a polyurethane or a latex. A ready-made artificial grain sheet may then be applied, or the backer may be buffed and finished by a conventional leather finish.

Title: Method of preparing duplicating or negative master sheet
IPC: B41M5/04
Filed: 1956-11-21
Abstract: 844,695. Photo-mechanical printing surfaces. DITTO Inc. Nov. 21, 1956 [Nov. 21, 1955], No. 35553/56. Class 98(2) [Also in Group XVI] A method of preparing a master printing sheet comprises forming an assembly of sheets in contact with each other, the sheets comprising an original imaged sheet having text or design portions adapted to absorb heat in contact with a second sheet having a fusible coating thereon, exposing the surface of the original sheet to infra-red radiation to cause portions of the fusible coating corresponding to the text or design to adhere to the original sheet, and separating the sheets. The method is applicable to the production of master sheets for use in spirit duplicating processes, hectographic processes, and planographic or lithographic processes, the coating on the second sheet being chosen in accordance with the process for which the master to be prepared is to be used. As shown, the imaged original sheet 1 with the imaged side facing outwards is clamped, together with the second sheet 3 having a coating 4, on a cylinder 6 and rotated past a slot 9 in a member 8 beneath which is an infra-red source 10. The source 10 preferably has an intensity of 1,350 watts and is placed 1/16 inch from the surface of the original sheet. The rotation of the cylinder is such that the exposure time is 1/10 second. On removing the second sheet from the original sheet the back of the original sheet has imaged portions which correspond to and are a mirrorimage of the original image on the front of the sheet. The back of the sheet 1 may then be used as a master sheet for direct printing as in a spirit duplicating process. When the master is to be used in offset printing processes a direct reading image may be obtained by placing the original sheet face downwards on the sheet 3. Instead of a master sheet, a stencil or negative may be prepared by exposing the original sheet and a sheet coated with a marking medium which is opaque to ultra-violet radiation and yet becomes tacky or liquid when exposed to heat. After exposure the coating will be drawn away on the original sheet leaving a stencil or negative having areas transparent to ultra-violet light and corresponding to the original image and through which a sensitized plate may be exposed.
