Abstract: 914,721. Electric analogue computers. KENT Ltd., GEORGE. Jan. 15, 1959 [Oct. 17, 1957], No. 32526/57. Class 37. In a heat transfer multiplier using thermistors T heated by heaters +H, - H, a quantity Y is applied over switch contacts S1 during one half-cycle, and any difference between the potential at the tapping and the input Z is eliminated by the output from demodulator D1 adjusting the heating currents to thermistor T and thus the ratio K of the tapping so that Z=KY, i.e. K=Y/Z. Input X to the potentiometer P during the following half-cycle results in an output of YX/Z to amplifier A2, which may be measured by comparison with a voltage V in a further self-adjusting arrangement in which V is made equal to YX/Z and then measured.

Filed: 1972-07-13
Abstract: 1353429 Data transmission; transistor switching circuits INTERNATIONAL STANDARD ELECTRIC CORP 13 July 1972 [16 July 1971] 32732/72 Headings H4P and H3T An input signal at ENT operates through a light link CD to control the supply of equal and opposite constant currents I1, I2 to a telegraph line LT. A light-emitting diode D3 turns on a transistor Q0 when an input signal is present, so that a further transistor Q1 is on when an input signal is present and off if it is not. Q2 is on when Q1 is off, and Q5 is on when Q1 is on. Q2, Q5 respectively control current sources GI1, GI2, in which Q6, Q8, Q9 are on when Q2 is on, and Q3, Q10 are on when Q5 is on. Constant current I1 thus flows to the line LT through D1 from GI1, or else flows I2 from the line LT through D2 to GI2. An overvoltage on the line is sensed by conduction of further transistors Q4, Q7 according to its polarity, and these act to turn off the associated one of Q2, Q5, thereby turning off the constant current source which was up to that time conducting. The high impedance of the constant current sources limits to a safe value any current flow due to the overvoltage. Resistor potential dividers R20, R21 and R23, R24 reduce considerably the voltage appearing at the emitters of Q4, Q7 as a result of the overvoltage.

Abstract: 1,274,442. Applying pesticide in the form of a foam. A. S. MINTON. 9 July, 1969 [9 July, 1968], No. 32752/68. Heading A5E. Pests are killed by subjecting them to contact with an aqueous foam comprising a pesticidal agent. The pesticidal agent is defined as disinfecting and sterilising agents are includes gases with pesticidal action. The aqueous foam may contain a solution or suspension of the pesticidal agent and is produced by the use of a surface active agent and conveniently the surface active agent also has pesticidal properties. In a specific embodiment a commercially available bactericide is used which comprises 8 % by volume of quaternary ammonium bactericide and 16% by volume of a suitably synergistic non-ionic ethylene oxide condensate. Alternatively a volatile pesticidal agent such as formaldehyde or methyl bromide may be used or sodium bicarbonate. The foam is produced in a conventional foam making machine. The invention finds particular application in the application of pesticides to the interior of or the contents of closed containers such as vats, wall cavities and pipe-lines, in which the space becomes completely filled with the foam. Alternative applications are in the disinfestation of non-human animals such as sheep, killing weeds in growing crops, and for the disinfestation of buildings inhabited by animals.

Title: System of electrical picture transmission
IPC: H04N5/208
Filed: 1931-11-30
Abstract: 390,565. Television. TELEVISION LABORATORIES, Ltd., 505, Crocker Building, San Francisco, U.S.A. Nov. 30, 1931, No. 33164. Convention date, Dec. 4, 1930. [Class 40 (iii).] In television, the received picture signals are combined with impulses generated at the receiver, to form square-fronted waves, to compensate for the absence of high-frequency components in the received signals. The added impulses are preferably proportional to one or more derivatives of the received signal with respect to time, while the received signal has preferably had its high frequency components removed before transmission. The picture signals, produced at the transmitter as described in Specifications 368,309 and 368,721, are amplified at 18, Fig. 1, and fed into a low-pass filter 20 which removes the high-frequency components, before passing to the line 21. At the receiver the line 21 is shunted bv an inductance L in series with a resistance R, producing a voltage drop between the grid and the cathode of the screen-grid valve 26, thus introducing the first derivative. A similar shunt 27, 28 in the output circuit of the valve 26 introduces the second derivative and higher derivatives may be similarly added as desired. It is stated that it is necessary to introduce a derivative having a discontinuity at the instant when a picture impulse is received and that further derivatives are desirable to compensate for the effect due to the finite size of the scanning spot. Transmission may also be effected by modulating a wireless carrier wave, Fig. 7 (not shown), the received signals being amplified before the derivatives are added, Fig. 8 (not shown). An alternative shunt comprises a resistance 66, Fig. 9, in series with a condenser 67 and a resistance 68 in parallel, and if desired an inductance may be connected in series with the resistance 66, Fig. 10 (not shown). The line should have a high impedance and if necessary a resistance 22, Fig. I, or a condenser 65 may be connected in the line. Preferably the low-pass filter 20 attenuates frequencies above the highest frequency to be transmitted, proportionally to frequency. According to the Specification as open to inspection under Sect. 91, the invention is also applicable to telegraphy and the restriction of television signals to a small frequency band can allow the transmission of voice currents over the same channel. This subject-matter does not appear in the Specification as accepted.

The resultant filaments are heat-treated before during or after stretching the yarn, the heat treatment being carried out at a temperature above 200‹ C. and in the final stage at a temperature not lower than the temperature at which the ring closing degree of R 5 X and of R 6 X becomes more than 50% after 10 minutes heating. Stretching may be effeeted in one or two stages, using, e:g. hot liquid for the first or early stage and passage over a hot plate for the second stage. The filaments may be formed by extruding a solution of the polymer having a concentration of over 15% by weight into a bath of an aqueous solution containing over 30% by weight of calcium chloride and maintained at a temperature of 50‹ to 120‹ C. The filaments may be formed by dry sprinning a solution of the polymers having a viscosity of more than 800 poise at 25‹ C. The filaments formed may have a recurring ring structure having the general formula wherein R 1 , R 2 , R 3  and R 4  are each as previously defined. #y/#x in this formula may be <7/3, the ring closing degree of X may be more than 50% and the tenacity of the filaments may be higher than 1.5 g/d.

An hydraulic clamping-device for machinetool-slides, comprises a clamping-shoe or shoes operated by a piston-and-cylinder device or devices in which fluid is fed to the latter from a damping-fluid-chamber having a power-piston subjected to the action of a potential-energy source, release being effected by auxiliarypressure-fluid urging the power-piston against the action of the potential-energy-source. A machine-tool-carriage 2 sliding on a base 1 is clamped thereto by a pad 3 drawn up against a ledge 1a on the base and the overlapping part 2a of the carriage. The pad is pulled by a rod 4 connected to a piston 5a in a cylinder 6a of the carriage. Fluid-pressure for clamping is led into the cylinder through a conduit 9a, and the piston 5a operates against a spring 7a, which unclamps the parts when pressure is reduced. Clamping-pressure is effected by a mastercylinder 12 in which a strong spring 15 acts through a plunger 14 to compress fluid in the space 13 below the plunger. To unclamp the slide, a valve 21 is moved upwards by a solenoid 25 to admit pressure-fluid from a pump 16 and relief-valve 19 to the space 26 beneath the plunger-piston 27. Compensation for leakage in the clamping-system is effected by a further pump 30 which feeds fluid to a recess 29 around the plunger 14, which is uncovered each time the plunger reaches its uppermost position. Other forms of clamps, operated in a similar manner, are shown on the carriage 2.
