Title: Improved electrical measuring apparatus
IPC: G01R15/22
Filed: 1965-02-15
Abstract: 1,076,681. Measurement of condition of high voltage line; current and voltage measurement. ALLIS-CHALMERS MANUFACTURING CO. Feb. 15, 1965 [Feb. 24, 1964], No. 6384/65. Headings G1A and G1U. Apparatus to measure an electrical characteristic of a high voltage line and transmit a generated signal corresponding to this characteristic to a receiver at earth potential includes means producing a variable radiation signal, whose intensity is a function of the generated signal and which is transmitted by a fibre optic dielectric transmission means. The alternating current in a high voltage line (10) is sensed by a current transformer (12) having its secondary inductively coupled to the high voltage conductor which forms the primary to produce a varying signal which is used to modulate an infrared emitting gallium arsenide diode (20). The diode is biased negatively at a constant voltage by the output from a current transformer (27), which is rectified (28) and filtered by a low pass filter (22), giving a quiescent operating point at about the midpoint of its currentlight characteristic. A resistor (23) and capacitor (25) help to establish the selected value of bias current and a diode (24) prevents reverse voltages from appearing across the source (20). The modulated radiation output of the diode thus represents the full sinusoid of the line current waveform. The radiation is transmitted by the fibre optic device, enclosed in a sealed porcelain tube (33) to prevent formation of a conductive layer of moisture on the fibre, which connects the high voltage circuit to the receiving and operating devices at earth potential. The radiation is detected by a photo-multiplier, the output of which is amplified (16) and fed to the operating device (17). The amplifier may only transmit the A. C. component of the photo-multiplier output, thus restoring zero crossings to the signal.

Title: Improvements in or relating to means for depositing films of metal on a series of plates or sheets
IPC: B05B15/04
Filed: 1945-03-15
Abstract: <PICT:0589581/III/1> In a method of depositing films of metal on a series of plates or sheets by spray painting, the metal is sprayed through a series of masks cut in paper or other material of small value compared with metal, each mask being discarded at or before the stage at which the margin has become contaminated sufficiently to require cleaning.  As shown, applied to an apparatus for coating a series of mica plates in succession, paper 3 is passed in step by step motion, imparted by a ratchet 16 and a friction drum 5, under a hole-punching device 25 and on to a spraying station where a mica sheet, removed from a magazine 36 in which a number are stacked, by means of a suction nozzle 38, is deposited on the aperture. Metal from an automatically-operated spray gun 35 is deposited on the exposed portion of the mica which then moves forward to a point where a second suction nozzle removes the coated sheet and transfers it to a travelling belt for further processing, e.g., heat treatment, the paper being discarded.  The sequence of operations is controlled by cams operated by a continuously rotating shaft 9.  The second Provisional Specification relates to the construction and operation of the magazine 36 and states that it may be used for purposes other than in the apparatus described above.  Specification 589,582 is referred to.

Title: Improvements in the production of non-knocking motor spirit
IPC: C10L1/06
Filed: 1930-02-28
Abstract: Non-knocking motor spirit is obtained by adding to a liquid fuel obtained by destructive hydrogenation a spirit obtained by the pyrolysis of gaseous hydrocarbons, usually the waste gases from the destructive hydrogenation process.  1 part of pyrolysis spirit to 54 parts of destructive-hydrogenation spirit is suitable.  Preferably (1) The ethane and methane to be submitted to pyrolysis are first separated from the other destructive-hydrogenation gases, e.g. by absorption in petrol or gas oil under pressure, they are released by reduction of the pressure.  (2) The pyrolysis spirit is desulphurized and otherwise purified by caustic soda, sulphuric acid, and fractional distillation; or the gases are desulphurized in known manner before pyrolysis.  (3) The pyrolysis treatment consists in passing the hydrocarbon gases through a refractory tube heated to 1000-1200 DEG  C. as described in Specifications 342,319 and 342,359, [both in Group IV).  The gases are recirculated until the desired proportion of pyrolysis spirit has been produced.  (4) The waste gases from the pyrolysis process are treated with steam or in other known manner to furnish hydrogen for the destructive-hydrogenation process.  The destructive hydrogenation may include a vapour-phase treatment, e.g. as described in Specification 338,576, [Class 32, Distilling &c.], oils obtained by a previous destructive hydrogenation or any mineral oil being treated.

Title: Stereo-signal decoder circuits
IPC: H04H20/88
Filed: 1976-02-20
Abstract: 1536963 Stereophonic receivers SIEMENS AG 20 Feb 1976 [13 March 1975] 06724/76 Heading H4R In a stereophonic signal decoder circuit in which a sum signal L+R and a difference signal L-R are fed to a matrix to derive the L and R signals for reproduction, the difference signal L-R is fed to the matrix 3 via a differential amplifier type attenuator 6 which is controlled by a control signal Us applied to a control terminal 7. Preferably the control signal is varied with received signal level to provide a smooth change between monophonic reproduction at low signal levels and stereophonic reproduction at a high signal level, where the signal strength is adequate to provide good stereo separation. As described, the 38 kHz sub-carrier modulated with the stereo difference signal is applied to terminal 19 of a demodulator formed by transistors 10 to 15 fed also with the 38 kHz phase-locked demodulating carrier on terminals 45 so that opposite phase outputs +(L-R) and -(L-R) are developed to be fed into the common emitter circuits of differential amplifiers 23, 24 and 25, 26, respectively, in the attenuator circuit. The attenuator comprises four differential amplifiers having the bases and collectors of the transistors in the amplifiers commoned in differently arranged pairs so that a control signal Us applied to the input 31 provides variable attenuation in the transmission of the signals +(L-R) and -(L-R) to the output terminals 33, 34. The sum signal L+R is applied via transistors 33, 39, to the splitting transistors 41, 42 to be combined in the collector circuits with the attenuated +(L-R) and -(L-R) signals to form the left and right channel signals U L  and U R  which vary from fully independent L and R signals, when the attenuating factor b is 1 to identical L+R signals when the factor b is 0.
