Title: Improvements in or relating to the measuring of variables
Inventor: HUTCHEON IAN CARRODUS
IPC: G01N27/416
Filed: 1954-10-04
Abstract: 814,888. Electric tests. KENT Ltd., G. Sept. 30, 1955 [Oct. 4, 1954], No. 28566/54. Class 37.  The potential difference between the electrodes of a pH cell is measured by means of a condenser which is connected alternately to one electrode and one side of the input to the measuring network and to the other electrode and the other side of the measuring network. As shown, the electrodes GE, RE are immersed in a liquid of which the pH value is to be measured and which is earthed. The measuring network consists of an amplifier tube V feeding an amplifier A the output of which feeds a motor M to regulate the output of a potentiometer P. The bucket condenser C1 is connected to movable contacts K1, K2 which move respectively between connections D and B to the two electrodes and D1, B1, the amplifier input terminals. The potentiometer output is applied across B1 and to a further movable contact E1 which also connects the potentiometer output periodically to D1. Initially condenser C1 is connected between contacts B and B and is then transferred to contacts D and D1, the connection to contact D is broken and movable contact E is closed to fixed contact D1. If the voltage across input resistor Rg remains constant during a cycle the potentiometer output voltage is a measure of the difference between the electrode potentials and is independent of their potential to earth. If the potentiometer output differs from the electrode P.D. an alternating signal is produced the phase sense of which depends on whether the potentiometer output is too great or too small and which is used to drive motor M to reset the potentiometer. The movement of the motor is an indication of the required P.D. When the potentiometer has a low internal impedance it may be connected. in the line joining primary contact B1 to Rg (Fig. 3, not shown) or, in series with a further resistor Rb across resistor Rg when the travelling contact may be omitted. In a still further embodiment (Fig. 5, not shown), the potentiometer is inserted in the earth line and a fixed resistor replaces the moving contact to join contact D1 to earth. Specification 695,909 is referred to.

Title: Improvements in or relating to electromagnetic relays
Inventor: TOWNER STANLEY HERBERT
IPC: H01H51/22
Filed: 1948-11-04
Abstract: 650,919. Electromagnetic relays. STANDARD TELEPHONES & CABLES, Ltd. Nov. 4, 1948, No. 28674. [Class 38(v)] A polarized relay particularly adapted for operation by D.C. superposed on an A.C. supply, has a shortcircuited coil A arranged on a branch of the magnetic circuit so as to vary the phase of the flux in that branch relatively to the flux in another branch whereby the resultant flux through the armature will have a smaller amplitude of fluctuation and the armature will be less liable to vibrate. In the ideal case, the phase difference is one half-cycle, equal flux is induced in the two branches and the resultant flux through the armature is equivalent to that obtained by D.C. only. In Fig. 2A the operating coil is mounted on the armature which moves between two poles on one of which the coil A is mounted. In a modification, Fig. 2B (not shown) the armature is bifurcated with the coil A on one of the prongs. Fig. 3B shows a different type of magnetic circuit with operating coils on the fixed parts and a resistance C included in the short-circuited winding. In a modification, Fig. 3A (not shown) instead of a separate coil, the top part of the operating winding is itself short-circuited by a resistance.

Title: Improvements in or relating to methods of making electrical conducting patterns suchas wiring circuits for radio receivers
IPC: H05K3/12
Filed: 1947-10-30
Abstract: 635,947. Printed circuits. CLARKE, A. G. Oct. 30, 1947, No. 28935. [Class 36] An electrically-conductive pattern is applied repeatedly by means of a fluid medium to consecutive sections of a sheet of insulating material. In one method of carrying this out a continuous web 10 of insulating material is passed intermittently through a printing- machine 12 where the highly conductive parts of the desired circuit are printed on the web, while said web is stationary, the printing fluid comprising a paste containing colloidal silver. The printed section of the web passes to a heating chamber 13 where the paste is dried to form a hardened, adherent and conductive film. This section of the web then passes to a printing-machine 14 where less conductive parts of the circuit are applied by means of a printing fluid such as a resin emulsion or a lacquer solution containing colloidal graphite and larger particles of carbon. This part of the circuit is dried in heating chamber 15. The completed circuit then passes through a punching press 16, where perforations are made in the terminal areas of the pattern for the reception of eyelets or rivets, and finally through a guillotine 17 where the completed circuits are severed from the web. A second method uses a non-conductive fluid in the printing-machine 12, the web then passing through an insufflating chamber, where finelydivided metal powder is sprayed or blown on to the surface and adheres only to the printed parts thereof, before the web reaches the chamber 13. The non-conductive fluid may be an unpolymerized resin. In a third method a light-sensitive silver salt is incorporated in the printing paste in the machine 12. This is subsequently exposed to light and washed before reaching the chamber 13. In a fourth method the printing-machines are replaced by stencilling-machines. In all the above methods patterns may be applied to both sides of the web simultaneously. If desired, the punch 16 and guillotine 17 may be omitted and the web may be passed continuously through the machine, being taken up on a roll as it leaves the chamber 15, the punching and cutting operations being performed later. The completed circuit may be secured to a self-supporting rectangular frame, or the desired degree of rigidity may be obtained by folding or bending the sheet, for example into zig-zag formation, or by rolling, the plies of the sheet being interleaves with insulating material and a conductive screening foil if necessary. The web 10 may be made from polyvinyl chloride, polystyrene, polythene, or cellulose acetate and may be loaded with ceramic material or mica.

Abstract: 813,384. Hand looms. EPSTEIN, H. Oct. 14, 1955 [Oct. 18, 1954], No. 29346/55. Class 142(2) A hand loom comprises a base portion 1 carrying pins 2 and an upper member 10 having prongs 12 which mesh with the pins 2 to displace some of the warps to form a shed. To set up the loom, a continuous length 5 of warp yarn is laid in alternate longitudinal channels formed by the pins 2, a length of weft 6 is laid in alternate transverse channels, and a further length 7 of warp yarn is laid in the longitudinal channels not occupied by the yarn 5. The upper member is pressed on to the base portion and depresses the yarn 7 below the level of the yarn 5 and a weft is inserted between the yarns 5 and 7 by a needle pushed through a slot 16 and along a groove 4. The member 10 is then removed and reapplied above the next groove 4 and a further weft inserted. Only the alternate wefts in the finished fabric are inserted by the needle, the intervening wefts 6 being laid in when the loom is set up. A guide bar 15 may be used to position the upper member over the base. Partitions 13 on the member 10 fit between the pins 2 and ledges 14 govern the depth of engagement of the members 1 and 10. By arranging the prongs 12 in appropriate groups, different weaves can be obtained. The parts 1 and 10 are made 'of a heat setting plastic and may be a styrene acrylonitrile copolymer and can be made by injection moulding. The pins and prongs are spring-like. The prongs 12 may have a cross section as shown in Fig. 8, which shape prevents lateral and longitudinal displacement of the tool 10 and the bar 15 is not required.

Abstract: 702,218. Automatic exchange switches. TELEPHONE MANUFACTURING CO., Ltd. Nov. 30, 1951 [Dec. 1, 1950], No. 29487/50. Class 40 (4) An electric connector switch comprises a member adapted to be stepped by the pulsing of a polarized electric motor and arranged in each position to close or open a set of contacts associated with that position. The motor 24 which is of the type described in Specification 672,140, [Group XXXV], has a rotor having two stable states of equilibrium which it is prevented from reaching as described' below. On being alternately impulsed with currents of opposite polarity the rotor reciprocates to produce a corresponding motion in the lever 33 which is fixed to the rotor spindle. The lever 33 carries a pin 34 slidable in a groove 31b of the pawl arm 31 which is pivoted at 32. The pins 31a of the pawl 31 are arranged to step the ratchet wheel 30 whose teeth are separated by a space having an elongated channel 30a in which the pawl pin resides at the end of the stroke to hold the ratchet firmly in position. The throw of the pawl and therefore also of the rotor is limited by the engagement of the pawl pins with the bottoms of the channels 30a. The distance of the pin 34 from the spindle of the rotor is readily adjustable so that the throw of the rotor may be adjusted to suit different impulsing speeds. The ratchet wheel 30 drives a splined shaft 10 carrying cams 10a ... 10g. Cams 10b ... 10g are staggered and operate contact sets 12 ... 17 successively during one half-revolution and sets 18 ... 23 during the other half-revolution. The contact sets 12 ... 21, 23 are made at every other movement of the pawl and at the intervening movements the interrupter contacts 11 are closed. The normally-made contacts. 22, broken by operation of the cam 10f, which is arranged to occur slightly early, i.e. so that the contacts are opened by the same pawl stroke which opened the preceding contact set. This may be arranged by a slight angular rotation of the cam 10f or preferably by a slight forward displacement of the spring set.

Title: Flavoring compositions
IPC: A23L27/40
Filed: 1966-06-30
Abstract: A material having the empirical formula C10H14O3S, given I.R. and N.M.R. spectra (Figs. 1 and 2) and given relative m/e intensities as shown by a mass spectrogram is produced by reacting thiamine or 3-acetyl-3-mercapto-propanol-1 in the presence of an organic carb oxylic acid.  This product is thought to contain carbonyl and ether groups.  Suitable organic acids are glutamic, glutanic, lactic, succinic, acetic, propionic, tartaric, aspartic and citric acids, glycine and particularly protein hydro lysates. The reaction is preferably carried out in the presence of a second sulphur-containing compound, e.g. a sulphur-containing amino acid, a mercaptan, an alkyl sulphide or disul phide, H2S or an alkali metal or alkaline earth metal sulphide.  The reactions preferably take place in water solution, and the desired product may be isolated by extraction with iso-pentane followed by gas-liquid chromatography tech niques.ALSO:The flavour and aroma of roasted meat are imparted to an edible composition by associating with it a material having the formula C10H14O3S, given I.R. and N.H.R. spectra (Figs. 1 and 2) and given relative m/1 intensities as shown by a mass spectrogram.  This material is produced by reacting thiamine or 3-acetyl or 3-acetyl-3 mercaptoproparol-1 in the presence of an organic carboxylic acid, e.g. a protein hydrolysate, preferably in the presence of another sulphur-containing compound.  The reaction product may be extracted by gumarabic and dried, e.g. spray-dried, or the compound C10H14O3S may be isolated by gas-liquid chromatography.  It may be used in a pure or impure condition, e.g. a beef bouillon cube may be formed by mixing the impure product of the above reaction, gelatin, monosodium glutamate, colouring, garlic and pepper, or a gravy may contain this product with cornstarch, caramel colour, garlic, pepper, salt and monosodium glutamate.  A soup may similarly be prepared if mixed vegetables are added to the mixture.
