Title: Improvements to coded transmission systems
IPC: B23B51/04
Filed: 1961-11-10
Abstract: 949, 808. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 10, 1961 [Nov. 16, 1960], No. 40394/61. Addition to 892, 552. Heading G4H. [Also in Division H3] The invention resides in an improved circuit for receiving code signals of the type disclosed in the parent Specification in which the code elements are of constant duration, each element commencing with an initial transition between two signal conditions, those elements having a further transition at their mid-points representing "I's", and those having no such further transition representing "O's". The initial transitions serve for synchronizing the receiver, and the circuit of the invention ensures that synchronism is not lost when initial transitions are obliterated or additional transitions are inserted (see second element of line a, Fig. 2) owing to interference. Complementary signals a, b, are applied to detector DT Fig. 1 which produces a short pulse c for each transition. Monostable circuit RA is triggered on (pulses d) by a pulse c for a time <SP>T</SP>/ 4  (where T is the element duration). At the end of a pulse d, monostable circuit RB is triggered on (pulses f ) for a time <SP>T</SP>/ 2  , and at the end of a pulse f, monostable circuit RC is triggered on (pulses h) for a time <SP>3T</SP>/ 8 . After being triggered on, monostable circuit RA is prevented from being triggered again for a time <SP>3T</SP>/ 4  by means of pulses d,f. At a time <SP>3T</SP>/ 4  after a pulse c from an initial transition RA is unblocked ready to be triggered in response to the next initial transition, but if this transition is missing, RA is triggered on by a pulse i from FC after a further delay of <SP>T</SP>/ 8 . H the next initial transition occurs correctly, synchronizm is exactly restored. Short pulses e,g generated by FA, FB are used to derive the output signals from the circuit, Bi-stable circuit BA is set to a state corresponding to the signals a, b at a time <SP>T</SP>/ 4  after an initial transition and the output j is applied to bistable circuit BB. At a time <SP>3T</SP>/ 4 , BB assumes one state (o) if the signals a, b and j correspond (i.e. no change between <SP>T</SP>/ 4  and <SP>3T</SP>/ 4 ), or the other state (I) if the signals a, b and j do not correspond. The two erroneous transitions shown in Fig. 2 would cause circuit BB to be erroneously set to state O during the second element because the signals a, b are the same at <SP>T</SP>/ 4  and <SP>3T</SP>/ 4  ,but such an error would not cause loss of synchronizm and may be detected by using an error-detecting code. The receiver may be automatically adjusted to synchronizm at the start of, or at intervals during transmisions by transmitting a train of "O's". The receiver then moves towards synchronizm in steps of <SP>T</SP>/ 8 .

Filed: 1971-09-07
Abstract: 1320086 Determination of enzyme concentration BOEHRINGER MANNHEIM GmbH 7 Sept 1971 [11 Sept 1970 15 June 1971] 41657/ 71 Heading B1X The concentration of enzymes, e.g. endoenzymes, which hydrolise, e.g. polysaccharides, proteins or esters, is determined with an agent which comprises an enzyme-hydrolisable, water insoluble or insolubilised and optically or photographically evaluably marked substance dispersed in an inert carrier matrix which permits diffusion of any hydrolised fragments of the dispersed substance. The agent is supported by e.g. a glass or resin plate or a transparent or opaque foil. Application of test sample to the agent causes hydrolysis of the marked substance when hydrolysed fragments diffuse through the carrier matrix to leave an unmarked test area from which the concentration of enzyme can be found by comparison with standard results. The carrier matrix may be agar, agarose, pectin gelatine, starch, quarane, polyacrylamide, silicate gel, cellulose or filter paper. The dispersed substance may be starch, cellulose, dextran or a protein cross-linked with diepoxide and may be marked with a dyestuff, a fluorescent substance or a radioactive agent (all specified). If water soluble the substance to be dispersed can be insolubilised by cross-linking, e.g. with halohydrins, isocyanates, isthiocyanates or epoxides, or by binding with activated particles of dextran, cellulose, polystyrene or glass. The test sample may be urine (for α-amylase), Penicillium funiculosum (for crude dextranase) or a solution which contained papain. Other enzymes are mentioned.

Abstract: 1,011,241. Measuring electrically. ENGLISH ELECTRIC CO Ltd. Nov. 24, 1961 [Dec. 8, 1960], No. 42260/60. Heading G1N. A variable-Q transducer, Fig. 1, comprises a coil 4 wound on a closed core which is made of magnetic material having high electrical resistivity, e.g.ferrite material, except for an insert 3 of magnetic material having relatively low electrical resistivity, e.g. mild steel, and a magnetic armature (not shown in Fig. 1) of high resistivity, e.g. ferrite, which is movable towards and away from the insert so as to vary the Q of the coil. In Fig. 3, the transducer is shown potted in a box of insulating material with the end of the core containing insert 3 protruding to form a head 9 which co-operates with ferrite armature 10 mounted on a non-magnetic beam 11 which is pivoted at 12. A force at 14, produced, e.g. by a pressure-measuring bellows or bourdon tube, tends to displace the armature relative to the head thus varying the output of a displacement detector and signal circuit 17, which output is supplied to a coil 15 carried by the beam and disposed within the air-gap of a permanent magnet 16, to exert a restoring force on the beam. The signal current, which is proportional to the displacing force, is also used to actuate means not shown for indicating, recording, controlling &c. The coil 4 comprises three windings, Fig. 4: a tuned circuit coil T1, 2, an oscillor feed-back coil T3, 4, and an output coil T5, 6, connected in circuit with a class C transistor oscillator TS1, the amplitude of whose oscillations varies with the Q of the transducer. The oscillator output is fed to an output transistor TS2, working in class B, smoothed by a capacitor C4, and dropped across a load resistor in the power line. Alternatively, the output stage may comprise two transistors in a push-pull arrangement.
