Title: Process for the manufacture of polymerisation products
IPC: C08F24/00
Filed: 1936-12-22
Abstract: Polymerization products are prepared by the polymerization of 2-vinylfurane in aqueous emulsion.  The polymerization is accelerated by oxygen or oxygen-yielding compounds and retarded by sulphur or sulphur-yielding substances.  The polymer is obtained as a light-coloured material resembling latex from which the polymer can be precipitated, if desired after the addition of fillers, softening agents or other plastic materials.  When freshly prepared the polymer is thermoplastic, is insoluble in ligroin and alcohols but soluble in aromatic and chlorinated hydrocarbons, esters and cyclic bases; it is self - hardening, oxygen being absorbed, but this tendency can be counteracted if desired by the addition of aromatic amines or hydroxy compounds. The polymerization may be carried out in the presence of other polymerizable substances, e.g. butadiene, styrene, vinylalkyl ketones and acrylic or methacrylic nitrile.  In examples: (1) 2-vinylfurane is stirred or shaken with a solution of sodium oleate and potassium sulphate, phenyl-b -naphthylamine is added to the latex and the polymer precipitated with alcohols, salts or acids.  The product is soluble in benzene, carbon tetrachloride, ethyl acetate and pyridine.  The sodium oleate may be replaced by stearates, linoleates or a sodium dialkylnaphthalene sulphonate; (2) 2-vinylfurane is shaken with a solution of o  - diethylamino - 4 - ethoxyoleylanilide hydrochloride and hydrogen peroxide, the polymer being precipitated by alkali; (3) a mixture of styrene and 2-vinylfurane is shaken with a solution of sodium oleate and potassium persulphate, and a small amount of the condensation product of a -naphthylamine and aldol is added.  Films may be obtained by evaporation of a solution of this product in ethyl acetate, toluene, butyl acetate, xylene and piperidine; (4) acrylic acid nitrile and 2-vinylfurane are shaken with a solution of sodium oleate and potassium persulphate, the paste formed is admixed with 1-phenylamino-8-aminonaphthalene, dissolved in benzene and the polymer precipitated by methanol; (5) butadiene and 2-vinylfurane are shaken with sodium oleate and potassium persulphate, phenyl-b -naphthylamine is added and the polymer is precipitated by acetic acid.  The product may be mixed with carbon black and heated in the presence of accelerators to produce p  vulcanizates.

Filed: 1969-07-14
Abstract: 1281698 Metallic photographic plates bearing conductive metal images ITEK CORP 14 July 1969 [15 July 1968] 35288/69 Headings G2C and G2M A developed photographic plate is obtained by exposing and physically developing a photo-sensitive layer of silver halide in a binder which is deposited on a receptive metallic support (i.e. a metallic support which has been physically or chemically roughened in order that a metallic image deposited thereon by physical development will be adherently bonded to the support or a physically smooth support which by chemical means will form an adhesive bond with the metal image deposited thereon by physical development), wherein the developed image is a coherent, conductive metallic image adherently and conductively bound to the metallic support. The binder layer preferably is 10 microns or less thick and is preferably permeable to the solvent used in physical development. An insulating layer which is permeable to the solvent used in physical development may be present between the support and the binderlayer. The insulating layer may be an oxide of the support metal or a gelatine layer (Example 1). The support may be aluminium, aluminium-manganese alloy or steel. The metallic image may be copper, silver or silver and copper. After image formation the silver halide layer may be removed by washing. In Example 1 the silver image is treated with a copperizing solution and dilute phosphoric acid to produce a printing plate. In Example 3 the silver image of Example 1 is coated with a lacquer which adheres to oleophilic surfaces in preference to hydrophilic surfaces to form a printing plate and additionally with a clear lacquer for use as a label. In Example 5 the silver image is treated with 2-mercaptobenzothiazole and 85% H 3 PO 4  in water so that it will accept greasy printing ink, and the unexpected areas will accept water. Reference is made to copending Specifications 1281697 and 1281699.

Title: Improvements in toll telephone systems
IPC: H04M15/08
Filed: 1929-11-20
Abstract: 343,518. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Verlooy, J. P.; 18, Rue Boudewyns, Antwerp, Belgium.) Nov. 20, 1929, No. 35477. [Class 40 (iv).] In a system in which toll calls from a number of local exchanges are recorded and completed over cordless positions by toll operators, checking circuit to the originating exchange may be established automatically on the depression by the toll operator of a key individual to the connecting circuit in use and a checking key common to the toll position. The toll operator may then complete the checking circuit by dialling the calling party's number, or may give instructions to the local operator for checking. The Figure shows a toll position TP for dealing with calls received over junctions TK from four local exchanges, the connecting circuits terminating in switches DF, TF. Each finder DF has four wipers and the d terminals of all the junctions from each exchange are strapped together and connected to the corresponding position relay I-IV. Depression of the listening key LK and the common checking key CK therefore operates the relay corresponding to the originating exchange. The checking junctions CT terminate in finders CF, and the operation of one of the relays I-IV starts the finders of the junctions leading to the corresponding exchange and marks the checking circuit of the toll position TP in their banks. Another arrangement is described in which the connecting circuits have access to all the checking junctions over a forwardly-hunting switch, those of the originating exchange being rendered selectable by the operation of one of the relays I-IV, as shown in the Figure.

Abstract: 503,310. Centrifugal pumps. SULZER FRERES SOC. ANON. Dec. 7, 1938, No. 35674. Convention date, May 7. [Class 110 (i)] In a pump unit comprising a main centrifugal pump 2 and auxiliary priming pump 3 with a passage from the outlet 8 of pump 3 to the inlet 5 of pump 2, a non-return -valve 16 is placed between the inlet 5 and the passage which has an air outlet 13 closed by a valve 14. The passage may comprise pipes 9, 15 and reservoir 10 always containing sufficient liquid passing through pipe 17 and valve 18 to prime pump 3 which draws air from inlet 5 by pipe 6 and inlet 7. Valve 14 is preferably either a float or connected to a float so that the air outlet is closed when the.liquid in reservoir 10 and valve chamber 12 reaches a predetermined level. On starting, pump 3 draws air and then liquid from inlet 5 until reservoir 10 is filled sufficiently to cause valve 14 to close outlet 13, when the pressure developed in pipe 15 opens valve 16. On stopping, the draining of inlet 5 draws liquid through pump 3 from the upper part of reservoir 10 so that outlet 13 opens and valve 16 closes, the air from outlet 13 passing through pump 3 to outlet 5 to completely empty it. The reservoir 10 may be dispensed with and pipe 9 connected to chamber 12.

Title: Improvements in and relating to Inverters
IPC: H02M7/538
Filed: 1966-08-10
Abstract: 1,157,888. Inverting. VARO Inc. 10 Aug., 1966 [10 Aug., 1965], No. 35809/66. Heading H2F. An inverter comprises a power amplifier fed with a high frequency square wave, the output from the amplifier being modulated with a low frequency control signal, and the output from the modulator being fed to a filter which extracts the low frequency component. The high frequency squarewave signal is derived by feeding bi-stable circuit 4, Fig. 1, with the output from oscillator 3 and is amplified by power amplifier 6 to provide a high level squarewave signal at the input of modulator 7. A comparator unit 9 is fed with the high frequency signal from oscillator 3, a low frequency sinewave from reference oscillator 12, and the low frequency output signal from the unit. The resulting output from the comparator is a pulse train at the high frequency, width modulated with the low frequency. This signal actuates a further bi-stable circuit 10, the output from which is mixed with the power amplifier output in unit 7 to produce a high level pulse width modulated signal. The output from unit 7 is then fed through a lowpass filter to derive the low frequency sine-wave signal. The circuit may be modified, Fig. 34 (not shown) by providing two power amplifier channels fed with 90-degree phase shifted inputs and each associated with its own comparator channel. Three comparator channels may be used with a signal power amplifier to give a three phase system, Fig. 28 (not shown). The system of Fig. 34 (not shown) may also be modified for polyphase use. The comparator unit. Fig. 2, comprises a sawtooth generator 24 which is synchronized with the high frequency signal applied at terminal 35, and a tunnel diode 25 which is switched by the sawtooth to produce a squarewave output. The low frequency signals from the reference oscillator and the filter output are applied at inputs 41, 44 and modulate the switching threshold of diode 25 so that the output pulse train is width modulated, Fig. 11 (not shown).
