Title: Improvements in or relating to electric pocket torches
IPC: H01H37/04
Filed: 1958-05-14
Abstract: 843,454. Electric battery lamps. WORTMANN, H. May 14, 1958 [May 16, 1957], No. 15376/58. Class 39(2). An attachment for a battery powered electric lamp of the type in which all the elements are contained in a common casing for holding in the hand, includes a bimetallic switch so arranged that when it is attached to the lamp and the main switch of the lamp is in the "on" position, current flows through the lamp bulb via the bimetallic switch. The latter is thereby heated and caused to break the circuit so that an intermittent light is produced. In a cylindrical torch 1 the device may be carried in a cap 3 at the opposite end of the torch to the bulb. An insulating cup 5 is mounted in the cap and carries a metal cup 6 engaging a coil spring 8 pressing on the end of the battery. The casing is connected to a bimetallic strip 11 round which a heating wire 13 is coiled, the end of the wire terminating in a contact on the strip co-operating with a fixed contact 10 connected to the cup 6. A sliding switch 14 is mounted on the end of the cap for short-circuiting the strip 11 so that a continuous light is produced.

Title: Treatment of water
IPC: C02F1/42
Filed: 1943-09-21
Abstract: Raw water containing alkaline and neutral metal compounds dissolved therein has the alkalinity reduced by passage through hydrogen-ion exchange material in a first portion of which a hydrogen-ion exchange is effected, and in a second portion of which the reverse action of metal-ion exchange occurs whereby the acids arising from the action in the first portion are re-converted to the neutral salts but the alkalinity, such as that arising from carbonates, which is removed in the first portion is not, or is only slightly, restored.  The result is that the final effluent is reduced to an alkalinity value slightly alkaline to methyl orange.  Regeneration with acid and rinsing is effected only in the first portion there being means to divert the effluent so that any excess acid is prevented from passing to the second portion.  The two portions of hydrogen-ion exchange material may be in the same container or in two separate containers with the quantities chosen so that the ratio of material regenerated to material not regenerated is equal to the ratio of the alkaline to the neutral salt in the raw water.  Specification 497,943 is referred to.

Abstract: 1,147,023. Determining water content of oil electrically. NIPPON OIL CO. Ltd. April 12, 1966 [April 12, 1965], No.15952/66. Heading G1N. Apparatus for measuring the water content of oil comprises a capacitor C 2  immersed in the oil and connected in a transformer bridge with a first variable capacitor C 0  (which is adjusted to balance the bridge when capacitor C 2  is immersed in waterfree oil) and a second variable capacitor C 1  having rotatable blades which are continuously driven by hand or motor 7 synchronously with a triangular wave generator 8, Figs.3, 4 (not shown). The output of the bridge passes through an amplifier 3 to a phase detector 2 and bi-stable circuit 6. A relay R L  closes a switch S  L  when the output of the phase detector exceeds a first predetermined level and opens the switch when the output drops below a second predetermined level. When switch S L  is closed, the wave generator 8 is connected to a recorder 9. The position of the rotary blades of capacitor C 1  at balance (and hence the recorded part of the output of the wave generator) depends on the water content of the oil. The recording, Fig.5 (not shown), comprises a series of M-shaped pulses, the height of which is proportional to the water content of the oil. A suitable frequency for the oscillator 1 is 1 kc. /s.

Title: Improvements in or relating to parametric amplifiers

Abstract: 1,019,393. Parametric amplifiers. SIEMENS & HALSKE A.G. April 24, 1963 [April 25, 1962], No. 16102/63. Heading H3B. In a parametric amplifier in which the variable reactance is a semi-conductor diode the difference frequency circuit comprises the mean barrier layer capacitance of the diode, the self-inductance and the casing capacitance of the diode, the signal circuit of the amplifier acting as a rejector for the difference frequency and as a path for the output frequency of the amplifier. As shown in Fig. 3,a barrier layer capacitive semi-conductor diode D is supplied with pump energy of frequency f(p) via hollow waveguide H and a signal S to be amplified of frequency f(s) via coaxial waveguide K, the guide K near its junction with the guide H being formed as a filter F which acts as a rejector for the difference frequency f(p)-f(s) but offers very little impedance to the pump frequency f(p). The guide H has a critical frequency above the difference frequency f p -f s  so that the guide H and coaxial guide K are completely decoupled from the diode device D at the difference frequency. A short circuiting slider Ks is positioned at a distance #p/2 or a multiple thereof from the diode so that the latter is at a current antinode of the pumping wave, with the result that the diode is current controlled and greater depths of modulation can be provided. In the embodiment of Fig. 4 (not shown) the coaxial guide K at a distance #d/4 from the junction of guide K with the hollow guide H merges into a low pass filter TP whose critical frequency is above the highest signal frequency but below the lowest difference frequency. The characteristic impedance of this #d/4 coaxial portion is such that the signal generator impedance is matched to the negative resistance of the diode and the signal circuit is tuned by the reduced part E of the inner conductor of guide K. Difference frequencies are prevented from travelling along the coaxial guide K by the rejector characteristic at the open end of the #d/4 portion.

Abstract: 1,149,191. Automatic pressure control. CESKOSLOVENSKA AKADEMIE VED. April 13, 1966 [April 13, 1965], No. 16170/66. Heading G3R. [Also in Division B1] The amount of at least one of at least two different fluids in a chemical analyzing chamber is controlled by a pressure sensing device communicating with the chamber to maintain a constant pressure in the chamber. In Fig. 1, a liquid and a gas, e.g. involved in chromatographic analysis, are supplied through tubes 18, 19 to a chamber 10 from which they may be drawn off through tubes 22, 24. A separate inert gas is supplied to a container 21 having rubber flexible walls, so as to acquire the same pressure as chamber 10, before withdrawal through a tube 23. The pressure within chamber 10 is maintained constant by supplying a further gas from a pressure source 1 through a coarse pressure stabilizer 3, an excess pressure limiter 5 and a fine pressure stabilizer valve 8. This gas is exhausted to atmosphere through a further pressure stabilizer valve 12. A pressure gauge 15 responsive to chamber pressure controls valves 8, 12 to maintain chamber pressure constant. Control of the valves, Fig. 6 (not shown), is effected through an electrical solenoid which adjusts a spring-loaded lever moving a resilient washer relative to the end of a pipe through which the gas passes. Manually adjustable restrictors formed of glass wool compressed by screws are provided on the supply side of the controlled valves. In a non-electrical embodiment the liquid and gas are alternately supplied to a chamber the pressure in which is maintained constant by an exhaust valve under the control of a lever operated by a float in response to change in level of liquid in a U-tube communicating with the chamber. Control of a pump instead of a valve supplying the chamber and control of chamber discharge only, are modifications referred to.

Abstract: 1,199,884. Electronic pulse circuits. AMPEX CORP. 28 March, 1969 [29 March, 1968], No. 16268/69. Heading H3T. [Also in Divisions G1 and G3] Timing errors in the pulses of a cyclic pulse train, e.g. errors due to inaccuracies in the machining of a tachometer in a motor speedcontrol system, are corrected by a delay device which is adjusted for each pulse to correct the pulse position. The circuit described is used in the servo control system of a tape recorder motor, the pulses being produced in a pick-up head 5 associated with a rotating member carrying magnetic elements in peripheral slots. The pulses are passed through a delay device 13 in the form of a mono-stable multivibrator having its delay controlled for each pulse in the cycle by respective resistors 65 and 66 arranged to correct the timing errors. The resistors are selected in turn by transistors 51-61 rendered conductive by gates 39-49 controlled by the outputs of a recycling register 17, 19, 21, 23, 25 driven by the input pulses via a delay 15. Synchronism is ensured by a further disc 9 providing resetting pulses.
