Patent GB-1544776-A (GB)
Title: Dental restorative composite
IPC: A61K6/884
Filed: 1977-02-08
Abstract: In the process for preparing dental materials which contain, as essential constituents, a liquid, organic, polymerisable binding agent and a finely divided filler, such a filler is used which consists to 70 to 95% by weight of particles having a granule size of 0.7 to 25 microns and 30 to 5% by weight of particles having a granule size of 0.2 to 0.7 microns. The dental materials are particularly well suited for preparing agents for preserving teeth by polymerisation because, as a result of the novel size of the granules of the filler, more of the filler than previously can be worked into the binding agent and the mechanical strengths of the polymers are higher.

Abstract: 1411919 - Continuous electrolytic etching SWISS ALUMINIUM Ltd 2 Feb 1973 [4 Feb 1972] 5395/73 Heading C7B A band of metal (e.g. Al) foil for offset lithographic printing or electrolytic condenser electrodes is continuously electrolytically etched by guiding in a path between electrodes immersed in a common bath and connected to an A.C. supply so that the band acts as an intermediate conductor. For etching one side only, the path of the band 1 may include reversals around rollers 3 in etching bath 2 as shown so that the electrodes 4-6, e.g. connected to a 3-phase A.C. supply R-T, are opposite the same side of the band. Alternatively the electrodes may be arranged alternately opposite one side and the other of the band for etching both sides. The number of electrodes may be a multiple of the number of phases of the voltage supply, successive electrodes being connected to different phases in sequence as shown. The band may be etched successively in several baths each having an A.C. supply so arranged that the band does not act as an intermediate conductor in passing between baths. The electrolyte may contain 0.3-3% HCl and 0.5-15 g/l ACCl 3 .

Divided out of 685,032, [Group XL(b)]. Class 40 (ii) [Also in Group XL(b)] In equipment comprising a tape for the recording and reproduction of electric signals and driving means for drawing the tape past recording and reproducing heads, the tape is fed by the driving means into a container having a width only slightly greater than that of the tape, is stored therein in the form of a plurality of loops, each loop comprising one or more folds of the tape, and is withdrawn therefrom by the driving means without interference between the different loops. The tape 3 is preferably of magnetic material or is formed of a substance, such as polymerized vinyl chloride, in which magnetic material is embedded, and is drawn by a driving roller 7 and its associated pressure roller 8 past the recording head 1 and a wipe-out head 4. The stored loop 10 of the tape is drawn past the reproducing head 2 by a roller 11, and stored as a separate bight. The tape can be fed reversely by a roller 18. When the reproducing head 1 is in operation independently of the recording head 1, and the tape becomes taut, a spring-biased arm 9 moves the roller 8 away from the roller 7 so that the tape can be drawn through the heads 1, 4. If the tape feed is obstructed in its passage to the reproducing head or to the recording head, the arm 9 or an arm 32 respectively closes contacts 13, 15 operating an alarm circuit. A break in the tape is detected by rollers 16, 17 arranged to complete an operating circuit for the alarm.

Abstract: 540,048. Coating and tinning metals; alloys; casting. GLACIER METAL CO., Ltd., HOLLIGAN, P. T., and BATE. J. March 28, 1940, No. 5599. [Classes 82 (i) and 82 (ii)] [Also in Group XXII] Metal articles are coated on one or more surfaces with aluminium or zinc or their alloys by first coating the surface with an alloy capable of alloying with both the metal of the article and the final coating metal or alloy, and maintaining such pre-coating in a molten state while applying a layer of the coating metal or alloy. The precoating alloy may be zinc with 0.05-3 per cent. of aluminium. A steel strip to be coated may be passed through a furnace in which it is heated to about 300‹C. and then between side guides arranged under the outlet of a pot of the precoating alloy and serving to confine the molten alloy to the upper surface of the strip, burners being arranged under this part of the strip to maintain the pre-coating alloy molten or the strip may be passed through a bath of the molten alloy. The strip then passes under or through a pot of the final coating metal similarly arranged. A zinc ammonium chloride flux may be used before applying the pre-coating alloy. The coated strip may finally be cooled by air or gas jets. The operations may be carried out in an inert or reducing atmosphere.

Title: Improvements in telephone systems
IPC: H04M5/04
Filed: 1952-03-04
Abstract: 700,844. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and FORBES, W. A. Feb. 11, 1953 [March 4, 1952], No. 5665/52. Class 40 (4) A manual P.B.X. attached to an automatic exchange is arranged so that a subscriber may dial into the automatic exchange and also signal the operator by means of a timing device which provides an exchange-hold condition after the end of dialling. When the operator plugs into an exchange line and throws a "straightthrough "key, feed relay A energizes over the subscriber's loop followed by guard relay B and sleeve relay S. The exchange line is thus looped and dialled impulses are repeated by A at contact a1. The first operation of dialling relay C connects up a vibrating relay V which is followed in turn by X; Y, the last relay locking. Relay V has a penduluin-type armature and although diseonnected after each digit maintains its contact intermittently until it is reset. After the last digit, its contact finally opens, and X falls back to loop the exchange line independently of contact a1. Any subsequent opening of the calling loop, provided it is of sufficient duration, releases R and lights the cord circuit supervising lamp, and the exchange line is held until the operator withdraws the plug. A thermal, clockwork or electronic delay device may be used in place of relay V.

Abstract: 684,013. Working metals. COMPTOIR INDUSTRIEL D'ETIRAGE ET PROFILAGE DE METAUX. March 8, 1951 [March 10, 1950], No. 5680/51. Class 83 (iv). Relates to the hot working of metals, particularly by drawing, extruding, flattening, flanging, rolling, and spinning, &c., and consists in the step of interposing a flexible sheet of lubricant between the heated work and the tool. The lubricant may be glass and this may be formed into fibres that may be woven, interlaced or otherwise intermingled with the addition of a binder if required. In a modification, the glass may be granulated and enveloped by or interposed in a felted fabric which itself may be a lubricant or in a flexible glass sheet as above. A flexible glass sheet may be prepared by coiling continuous fibres in a drum. The work is preferably heated by immersion in a salt bath, the coating of salt formed on the work aiding the glass sheet in adhering. Either the work or the tool may be covered by the sheet, e.g. by wrapping. For extrusion the heated billet is rolled on a sheet of glass cloth before introduction into the container and where tubes are to be extruded the mandrel is wrapped prior to introduction into a hollow billet. In forging, the die is covered by the sheet, the heated billet is superposed and covered by another sheet, and the operation is then carried out in the usual manner. Specifications 603,582, 607,285, 661,555 and 663,357 are referred to.
