Filed: 1965-04-30
Abstract: 1,073,397. Correcting jitter on playback of video signals. SONY CORPORATION. April 30, 1965 [May 2, 1964], No. 18304/65. Heading G5R. [Also in Division H3] Jitter in television signals played back from a magnetic recording apparatus 31 is eliminated by recording the signals on an auxiliary magnetic recording apparatus 35, playing back the signals from the apparatus, comparing the played back synchronizing signals with a standard, and adjusting the position of the playback head 18 in accordance with the error. In Fig. 3 a synchronizing unit 36 synchronizes the recording apparatus 31 and the drive motor 1 for a magnetic disc 7 on which signals from the apparatus 1 are recorded by means of a fixed head 11. The playback head 18 is mounted on an arm 16 rotatable by a control apparatus 15 of the moving coil type, and signals from the head are demodulated in unit 42 and supplied to a processing unit 43 supplied with blanking signals from unit 36. The unit 43 provides a video output at terminal 44 and a synchronizing signal output at terminal 45. A separating circuit 46 derives horizontal synchronizing signals from the output of demodulator 42, and after shaping in unit 47 these are compared with signals from unit 36 by detector 48 which supplies an error signal via amplifier 50 to the control apparatus 15. In a modification, Fig. 4 (not shown), the synchronizing unit 36 is omitted and unit 47 feeds an automatic frequency control circuit 53 to synchronize an oscillator, the output of which is compared with the output of unit 47 to derive the error signal feeding the control mechanism 15. In a further modification, Figs. 5 and 6 (not shown), either the record head 11 covers a wide track or it is replaced by two heads 11 and 1111 scanning adjacent tracks, and a fixed playback head 18<SP>1</SP> is arranged adjacent the movable head 18 to pick up only the synchronizing signals, which are fed to the control circuits. The recording apparatus 35 may use a drum instead of a disc, Fig 7 and 8 (not shown).

Abstract: 627,162. Rotary compressors and engines. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. July 11, 1947, No. 18415. Convention date, July 18, 1946. [Class 110(ii)] A helical screw pump or engine has a male rotor 20 provided with helical threads of convex cross-section lying substantially outside of the pitch circle d, e, and a female rotor having helical threads of concave cross-section lying substantially within the pitch circle of its rotor, the threads being shaped so that upon complete meshing, Fig. 8b there are no pockets of trapped fluid. Seals 56, 58, 60 may be provided as shown and some may co-act with recesses 74 in the meshing rotor. The threads and recesses of the rotors are preferably of symmetrical forms. In Fig. 3 a convex thread is formed by an arc a of radius R struck from a point P lying at the point of intersection of the pitch circle with a radius extending from the rotor axis and bisecting the cross-section of the thread. The portions f, g are curves of epicyclic form, but the whole cross-section is substantially circular. This shape of thread is stated to give a short sealing line when the rotors mesh. The upper part of a convex thread may be slightly flattened. Inlet and outlet ports may be axial-radial in direction. In one modification the threads may be formed "herring-bone" fashion with inlets at each end of the casing and a common central outlet port. Fig. 10 shows a discharge port 32 formed with a throat 62a. Sealing strips may be formed by peening the edges of threads. The relation of helix angle to rotor length is such that the extent of " wrap " of the male rotor threads from inlet to outlet will be not less than 90 degrees and less than 360 degrees. External gears couple the rotor shafts, the male rotor turning faster than the female rotor.

Title: Improvements in systems of electro-mechanical starting and operating from a distanceby multiple currents
IPC: B61L23/12
Filed: 1920-07-03
Abstract: 146,421. Mautsch, R. April 10, 1914, [Convention date]. Electric selectors.-In order to prevent a selector, used for exploding mines, controlling switches, locking railway signals, &c., from 'being operated improperly, switches are arranged at the receiver to vary the circuits of the electro-magnetic operating parts in such a way that in one position of the switches the selector can only be operated by certain currents sent over two live wires, whilst in the other position of the switches the selector can only be operated by different kinds of currents, so that at the controlling-station switching-operations must be made corresponding to those at the selector. The invention is described as applied to a selector for locking a railway signal lever 23, switches 31, 32 operated by the lever being arranged in one position to connect the windings 12, 13 of the soft-iron armature 9 in series with line 1, and the windings 7, 8 of the soft-iron core 6 in series with line 2, whereas in the other position, line 1 is in series with windings 13, 8 and line 2 with windings 7, 12. In the first position of switches 31, 32, the armature 9 can be oscillated to step around the escapement provided that the switch 22 (which is operated on the passage of each train), is in position to connect alternating current to wire 1 and direct or pulsating current to wire 2. The shaft 27 of the selector then allows a spring to unlock the lever 23 for operating the signal, the movement of which shifts switches 31, 32 into their second position, in which the escapement can be operated only by the currents sent when the switch 22 is in its other position, in which pulses of current over one line alternate with pulses of current over the other line. Two separate receivers may be employed, each responding only to one set of currents, and each operating to disconnect itself and cut in the other. The Specification as open to inspection under Sect. 91 (3) (a) states that the magnet 6 and armature 9 may be replaced by a motor, the operation of which may be modified in a similar manner. This subject-matter does not appear in the Specification as accepted.

Abstract: 295,680. I. G. Farbenindustrie Akt.- Ges. Aug. 17, 1927, [Convention date]. Medicines for internal use.-The hormone of the anterior lobe of the hypophysis is obtained from the urine of pregnant women, or from other huma.n or animal fluids or aqueous extracts of organs by precipitating the hormone by means of a large excess of alcohol, acetone, or like watersoluble organic liquid. Ovarial hormone may be obtained' from the alcoholic or like filtrate, or from the starting material prior to the precipitation, by extraction with ether, chloroform or other organic solvent which is immiscible with water. The urine &c. may be concentrated before treatment to obtain hormones. According to an example urine is concentrated, extracted with ether to remove ovarial hormone and treated with a large excess of acetone to precipitate the hypophysis hormone. This precipitate is taken up with water and fractionally precipitated with alcohol or acetone of about 40 per cent concentration to remove impurities but to leave the hormone in solution. According to another example urine is precipitated with a large quantity of alcohol, the precipitate taken up in water and further purified, and the filtrate is freed from alcohol, purified with lead acetate solution and extracted with ether to obtain the ovarial hormone The Specification as open to inspection under Sect. 91 (3) (a) includes examples according to which (i) urine preserved in an alkaline condition bv the addition of alcohol or cresol is concentrated at 40‹ C. in vacuo and then treated with a large volume of alcohol to obtain a crude precipitate and a crude filtrate. The precipitate is dissolved in weakly alkaline water, and centrifuged, and the clear liquid obtained is again precipitated with alcohol. These steps are repeated and the final solution is concentrated at 40‹ C. to a syrup which is dried in vacuo over calcium chloride and ground with absolute alcohol to obtain a. powder containing the hypophysis hormone, the physical and chemical properties of which are described. The crude filtrate above referred to is freed from alcohol, concentrated, mixed with kieselguhr and extracted with ether. The extract is dissolved in water, filtered, purified by heating with alcohol under a reflux condenser or by saponification with alkali, and the hormone then extracted from the solutions by means of ether, or precipitated with lead acetate and ammonia and extracted from the precipitate; (2) acetone is used as a precipitant for the hypophysis hormone and chloroform is used to extract the ovarial hormone. The chloroform extract is dissolved in water and purified by treatment with metallic salts, oxides, or hydroxides, or with metallic colloids, for instance with neutral lead acetate solution or dialysed ferric hydroxide solution.

Title: Improvements to ternary coders
Inventor: AVIGNON MICHEL LOUIS
IPC: H03M1/00
Filed: 1968-04-22
Abstract: 1,220,962. Analogue to digital converters. INTERNATIONAL STANDARD ELECTRIC CORP. 22 April, 1968, No. 18873/68. Heading G4H. An automatic calibration arrangement for centring the response curve of a feedback comparison ternary scale analogue-to-digital converter comprises means periodically to couple a calibration voltage to the converter, which should produce a predetermined ternary output when the converter is properly centred, and means detecting a deviation from this output which adjusts the centring to compensate for the deviation. A number of input voltages ec1 &c. and the calibration voltage eo are gated in turn to the input circuit NP. The calibration voltage is half the full scale voltage of the circuit. The maximum signal in a 5-digit ternary coder produces an output of 22222, and the half fullscale calibration voltage should produce an output of 11111. Each ternary digit is represented by two binary bits stored in register RG. The logical control unit LU sets the most significant digit in register RG to 2 (binary bits 1, 0) and comparator CM detects whether the input is exceeded or not by the output from decoder DC. This may be as described in Specification 1,219,148. If the input is exceeded, the first binary bit is reset to 0, giving a ternary digit of 1. If this is still too much the second binary bit is set to 1 giving binary 01, ternary 0. In the same way the pairs of binary bits are set in turn for succeeding ternary digits. These digits appear on flip-flop BD and are transmitted to an output A and serve to control the logical control unit LU. During the time calibration voltage eo is applied by gating signal Vs, the centering correction circuit CC is made operative. The pairs of two binary bits representing the successively lower ternary digits are examined and the first to have a value other than 1 are used to control the increase or decrease of the charge on a capacitor providing the correction voltage U. For a properly calibrated circuit every digit should be 1. If a digit is found valued 0, the charge decreases and if a digit is found valued 2, the charge increases.
