Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08J5/02
Filed: 1929-03-08
Abstract: 330,536. Dunlop Rubber Co., Ltd., Hayes, C., Madge, E. W., and Lane, F. H. March 8, 1929. Latex, treating. - In the process of obtaining articles from aqueous dispersions of rubber &c. by dipping, spraying, spreading, moulding, extending &c., the rubber is caused to gel in a controltable time which decreases with rise of temperature, by the addition of formaldehyde in excess of that required to neutralize the alkalinity of the dispersion, with or without the addition of a sensitizing agent. In the case of uncompounded latex, the formaldehyde alone is only effective if the ammonia content does not exceed 0.05 per cent; with compounded latices, this limitation is absent. In all cases, the greater the alkalinity, the greater must be the excess of aldehyde after neutralizing. Small quantities of sensitizing agents e.g. electrolytes such as zinc sulphate, ammonium sulphate, ammonium chloride, and ammonium salts of organic acids as oxalic, citric, tartaric, may be added to the latex to reduce the amount of formaldehyde required, or to enable the process to be worked with uncompounded. latex of high alkalinity. In a typical example, a concentrated latex containing 60 per cent of rubber and preserved with 0.38 per cent of ammonia is compounded to give the following mix; 100 parts of rubber, 3 parts of sulphur, 0.5 parts of accelerator, 1 part of zinc oxide, 3 parts of anti-ager, and 3 parts of oil. 5 per cent solution of zinc sulphate is added to provide 2 grams per litre. 20 cc. of a 15 per cent solution of formaldehyde in excess of that required to neutralize the alkalinity, is added per litre. The mix gels in 32 min. at room temperature. Specifications 219,635 and 290,313 are referred to.

Title: Telephone apparatus
IPC: H04M1/00
Filed: 1973-02-16
Abstract: 1435945 Telephone answering machines ANSAFONE Ltd 12 Feb 1974 [16 Feb 1973] 7783/73 Heading H4K An autodialler for use in a telephone answering machine having a call divert facility is arranged to automatically dial a predetermined substation, and the absence of the transmission of a code from the called substation to the autodialler after the called party has gone offhook causes it to be inhibited from dialling further calls to that substation. Receipt of a call on line 1 causes a message to be transmitted to the caller to ask him whether he wishes to record a message or to have the call extended to a further number. If the caller starts to speak, a message recording sequence is initiated. If the caller remains silent an autodialler 15 dials a further number over line 2 and a message is played to the caller to indicate that an extension of the call has been initiated. On the reply of the called party, a message is played over line 2 to request that an authorized person takes the call, and the equipment then awaits a coded command on this line. On receipt of the command lines 1 and 2 are interconnected. If however the code is not received, line 2 is disconnected, a message is sent to the caller indicating an unsuccessful call extension attempt together with a possible invitation to leave a message, and the equipment is inhibited from making any further calls to the particular number until reset. The resetting can be performed by an authorized person calling his own number and transmitting a predetermined code. In addition transmission of another code may cause any messages to be replayed to the person. In a second embodiment all callers on line 1 are invited to record a message, after a message has been recorded, the equipment dials a second number as described above. Receipt of a coded command causes the message to be replayed and non-receipt of the command causes line 2 to be disconnected and the equipment to be inhibited as previously described. In combination with either of the above arrangements, the equipment may be provided with means for dialling an emergency number in case of fire, burglary, flood &c., and then to dial a number where the owner might be present in a manner substantially as described above.

Abstract: 526,207. Artificial filaments. COURTAULDS, Ltd., STOKES, W. H., and ROSE, L. March 10, 1939, No. 7806. [Class 2 (ii)] Threads, filaments, and the like are obtained by extruding, into a coagulating bath, viscose containing one or more resin acids extracted from wood-pulp, or the alkali metal salts of such acids. The resinous substances may be extracted from the medullary ray fibres which have been separated from wood-pulp by washing. The resinous substances are also obtained as a scum on the top of the alkali refining and bleaching baths through which the pulp passes. The resins or their soaps are extracted from the crude material by extraction with a solvent such as acetone or hot caustic soda solution. If desired the resins may be oxidized before being incorporated in the viscose. The addition may be made at any stage of the manufacture of the viscose. In examples, pine resin soap is added to alkali-cellulose during the shredding process, or to the viscose during the step of mixing with caustic soda. The viscose is spun into an acid-salt bath.

Abstract: 1,212,388. Digital measurement of length. INTERNATIONAL BUSINESS MACHINES CORP. 20 Feb., 1968 [21 Feb., 1967], No. 8115/68. Heading G4H. [Also in Division 3 G1 and H4] In a scanning device two light beams each conveying an image of an article to be scanned are produced and one beam is passed through means which rotates the image about the axis of the beam without changing the direction of the beam. The means may be a Dove prism, a Pechan prism or may be as in United States Specification 3,030,857. With such an arrangement a single directional scanner can effectively scan an article in two directions without reorientation of the article relative to the scanner. As shown the article 90 is assumed to be in a set position and the scanner measures "the dimensions of the article. Light from a lamp is reflatted by the article to form an image although a shadow of the article is also said to be suitable. The image beam is collimated by lens 15 and applied to a beam splitter 16. The transmitted beam is rotated through 90 degrees about its axis by a dove prism 20 and after reflection at a mirror 23 is directed by a lens 15A on to a rotating polygonal mirror drum scanner 22. The reflected beam passes through a compensating block 25 and after reflection at a mirror 24 is directed by a lens 15B on to the same face of the mirror drum. Photodetectors 97 and 104 which may be photoconductors, photomultipliers, gas-filled or vacuum photo tubes or solid state detectors receive the transmitted beam via slots 96 and 102. Each photodetector responds for a duration corresponding to a dimension of the object, opening a corresponding gate 101 and 106 passing clock pulses from a common oscillator 99 to corresponding counters 100 and 107.

Convention date, March 15, 1929. [Class 29.] In apparatus for the partial liquefaction or separation by liquefaction of gaseous mixtures having two coolers, one of which is defrosted while the other is in normal operation, the defrosting is effected either by the whole or a part of the gas resulting from the liquefaction which is first passed through the cooler in normal operation and then through the cooler to be defrosted in the same path but in the opposite direction to its passage therethrough when the cooler is in normal operation. In the treatment of compressed coke-oven gas, the gas enters the pipe A and, assuming the cooler B is to be defrosted, passes through the cooler C, in which its condensable constituents, e.g. benzol, are deposited, to the outlet D which is connected to a lower temperature cooler. From the latter cooler issues gases rich in hydrogen, carbon monoxide or nitrogen, and marsh gas which enter pipes H, I, G respectively and pass through the tubes in the cooler C in countercurrent to the coke-oven gas to outlets H<1>, I<1>, N<1>, a part of the gases rich in marsh gas being diverted through the pipes of a steam-heater R to the cooler B to be defrosted and discharging therefrom through the outlet G<1>. Defrosting is effected when the fall in pressure of the coke-oven gas on the outer side of a cooler reaches one atmosphere.
