Title: Optical transmission device
Inventor: SAKAKIBARA MASAHIRO
IPC: H04J14/00
Filed: 1982-01-05
Abstract: PURPOSE:To simplify the system constitution, by transmitting a plurality of optical signals in one optical fiber with wavelength multiplex and receiving and processing them in time division at a reception side by means of variable filter characteristics of an optical branching filter. CONSTITUTION:Optical transmitters 101-10n transmit optical signals having lambda1 lambdan wavelengths, respectively. The signals are synthesized at an optical multiplexer 11 and the result is transmitted to the optical demultiplexer 12 at the reception side via the optical fiber 3. The filter consists of a wavelength selection filter prism, band pass type wavelength selection filter, which selects the optical signals of arbitrary wavelengths with a control signal from its control signal generating section and gives the result to a photodetector 14. The optical signals having lambda1-lambdan wavelengths are picked up at the photodetector 4 by means of the control section in time division sequentially or at random, and processed in time division.

IPC: B28B1/00
Filed: 1990-01-16
Abstract: The invention refers to a method of manufacturing intermediate concrete products, preferably tiles, which consists of casting non-segregable concrete mass of cast consistency into corresponding formworks. The concrete mass is cast by means of a charging head (4) and by discharging nozzles (6) arranged thereon, whereby the pressure of the concrete mass at the outlet of the nozzles (6) is adjusted to the largest cross-section of the product being cast and equals from 0,1 bar to 0,5 bar, preferably 0,2 bar. Nozzles (6) being pushed to the area of the bottom of the formwork (5) in the beginning of casting start to lift up when the concrete mass fills up the formwork (5) for essentially one third by the height. The lifting velocity of the charging head (4) and thereby of the nozzles (6) is adjusted to the cross-section of the product being cast, and equals from 0,05 ms<-><1> to 0,2 ms<-><1>, preferably 0,1 ms<-><1>. The invention also refers to a formwork for manufacturing concrete tiles and to an apparatus for carrying out said method. <IMAGE>

IPC: B22D11/00
Filed: 1988-01-26
Abstract: In a process for producing thin metal bar, in particular steel bar, having a thickness of less than 20 mm, an uncooled clean metal section having a low energy potential is placed in contact with a melt, which is made to crystallize on the format, the fitness of the metal bar being determined by the duration of contact. An economical process and a metallurgically usable product can be obtained by placing in contact a metal section (5) having a fitness of between 0.1 and 0.4 mm with a melt (4) for a certain maximum time which depends on the difference in energy potential between the low energy potential of the uncooled metal section (5) and the higher energy potential of the melt (4) before contact is made with the section (5). Depending on this maximum permissible contact time, a metal bar having a total thickness (12) of between 6 and 10 times the thickness of the section (5) is withdrawn from the melt; the bar consists of crystals which are deposited without interphase on the section and of other materials from the melt (4).

Abstract: 1,119,056. Radio signalling. STANDARD TELEPHONES & CABLES Ltd. 26 Nov., 1965 [27 Nov., 1964], No. 48246/64. Heading H4L. In a radio-communication system, e.g. a satellite system, subject to Doppler .effect, means are provided at a terminal station for generating a pilot frequency, and for transmitting and receiving the pilot frequency looped over the transmission path via a remote station, and variable delay and storage means controlled by the difference frequency between the pilot signal as transmitted and received compensate for the Doppler effect. As shown in Fig. 1, a frequency division multiplex baseband signal f s  at station A is sampled at frequency S 1 , coded and fed to a p.c.m. store S. Frequency S 1  = 2n P 1  is supplied as the write-in frequency to the store S via frequency multiplier X 1  from an oscillator OP generating the pilot frequency P 1 . The signal stored at S is then converted back to the baseband frequency using a read-out frequency S 2  which is controlled in accordance with the Doppler shift and is slightly lower than S 1  if the satellite path is shortening and slightly higher if the path is increasing. The pilot frequency P 1  is combined with the baseband signal at F 1  and after frequency-modulation at Fm, the resulting radio signal is supplied via the satellite to station B. The pilot frequency received at station B is modified by the Doppler effect and is selected by filter F 2  and fed back via filter F 3  for transmission back to station A, during which it is further modified approximately to the same extent. At station A a frequency 3P 1  is supplied to modulator M 1  via multiplier X 2  from oscillator OP, together with the pilot signal from filter F 4  and the lower sideband is extracted and multiplied by n at X 3  and applied as the read-out frequency S 2  to the store S. The receiver includes a similar p.c.m. equipment and store R and the write-in frequency for this store is derived from the upper sideband provided by a modulator M 2  from the received pilot signal and the frequency P 1  from oscillator OP which is multiplied by n at X 4 . The readout frequency for store R is 2nP 1 , the same as the write-in frequency for the store S. In an alternative arrangement, Fig. 2 (not shown), each terminal station transmits a pilot signal which is looped back at the satellite to the sending station. In this system the write-in frequencies of the stores R and S are varied and the read-out frequencies fixed. Further compensation may be effected by a secondary pilot frequency fed into the input of store S which on return is filtered out of the output of store R and via a 90 degrees phase shifter is compared with the original secondary pilot signal to control known means to modify the read-out frequency of store S in Fig. 1 or the write-in frequency of the equivalent store in Fig. 2. A method of setting up the equipment initially, by forming a local loop at the transmitter-receiver also is described.

Title: Improvements in or relating to the control of mercury arc rectifiers
IPC: H01J7/42
Filed: 1933-01-03
Abstract: 414,715. Metallic-vapour apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Witton, Birming- ham. Jan. 3, 1933, No. 186. [Class 39 (i).] In a vapour-arc converter provided with a vacuum gauze for indicating or for cutting out the converter when the vapour pressure reaches a predetermined value, wherein the pressure at the gauge differs from that in the rectifier in dependence upon the operating conditions, means are provided whereby the response of the gauge is automatically varied to compensate for the variation in the difference of pressures which may be due to stoppage of the evacuating pump or to variations in the load. A rectifier 1 is connected to a diffusion pump 9, a backing pump 10 and a Pirani gauge 11. A valve and a reservoir may be disposed between the pumps, and a mercury seal in the evacuating pipe 8 is adapted to close upon failure of the diffusion pump. The gauge comprises a Wheatstone bridge 13, across one diagonal of which is connected, through resistances 14, 15, a current source, and across the other diagonal of which is connected the coil 18 of an indicator and the coil 19 of a relay 20 which is adapted to close the circuit of trip mechanism 7 to open an oil switch 6. Upon failure of the current supply to the heater 23 of the pump 9, the coil 24 of a relay 25 is energized to connect the resistance 15 in the bridge circuit and thereby to vary the response of the gauge and of the relay 20. A resistance 27 in the load circuit is shunted by a coil 28 of a relay 29. When the load reaches a particular value, errors in the indicating or cutting-out apparatus are eliminated by the relay 29 which is energized to connect the resistance 14 in the bridge circuit. The relay 29 may be adapted to throw two resistances into the bridge circuit at different load values, and the series resistances may be replaced by shunts. The relays 25, 29 may be adapted to open and close with a time lag. In a modification, the diffusion pump is provided with heat storage means for maintaining the operation of the pump upon failure of the heating current therefor, and the relay 25 and a mercury seal in the pipe 8 may be energized in dependence upon the difference between the pressures in the boiler and in a stage of the pump. An ionisation gauge, consisting of a filament, an anode and a grid may be used, the adjustment being effected through a variable resistance in series with the cathode.

Title: Improvements in or relating to brake operating mechanism
IPC: B60T13/24
Filed: 1934-01-03
Abstract: 435,991. Fluid-pressure brakes. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H., Titanic Works, Lincoln. Jan. 3, 1934, No. 244. Addition to 389,775. [Class 103 (i)] The pneumatic operating device described in the parent Specification is used for the operation of vehicle brakes, a precompressed spring being coupled between the pedal or hand lever and the brakes whereby a valve mechanism is operated to supply power only when the effort applied to the pedal &c. exceeds a predetermined value at least sufficient to overcome the release springs of the brakes, while the power is cut off only when the effort falls below that value. The vacuum device shown comprises a valve casing 10 pivoted to an arm 11 on a rock-shaft 4 to which also are connected the rod 5 leading to the brakes and an arm 3 and link 2 connected to the piston of the cylinder 1. The pedal 8 is connected to a rod 9 slidable in the casing 10 and carrying the atmosphere valve 18 adapted to seat upon the vacuum sleeve valve 14 which under the action of a light spring 14b normally closes the chamber 13 connected by pipe 12 to the vacuum source. The cylinder 1 is connected by pipe 16 to the casing 10 and is normally open to atmosphere by way of the valve 18 and passages 15a. A precompressed spring 19 abuts on the casing and upon a collar on the rod 9, and the end 20 of the rod normally abuts on the casing as shown. When the pedal is operated the rod 9 and casing 10 with the pull-rod 5 at first move together until the effort on the pedal is sufficient to overcome the spring 19 whereupon the valve 18 seats upon the sleeve 14 and the sleeve valve 14 is moved in the casing to connect the cylinder 1 to the vacuum source. Should the power fail the brakes may be applied by manual effort alone. The system may be adapted for compressed air. According to the Provisional Specification the initial compression of the spring may be greater or less than that necessary to overcome the brake releasing springs.

Title: Charge coupled circuits
IPC: H01L27/148
Filed: 1972-01-05
Abstract: 1377521 Charge coupled devices RCA CORPORATION 5 Jan 1972 [6 April 1971] 385/72 Heading H1K In a charge coupled device the electrodes are arranged in groups of three the centre one of each group being biased with a constant potential and the other two electrodes of each group being fed with out of phase pulses each varying above and below the constant potential. A self scanning image sensor, Figs. 2 and 3 (and Figs. 1, 4 and 5, not shown) comprises an N type Si substrate 10 covered with an SiO 2  layer which is in the form of thick and thin parallel stripes, the thin stripes defining the charge transfer paths. A plurality of P + type poly-Si electrodes 16 buried in the oxide layer extend  transversely to the thin oxide stripes. Above each thin oxide stripe the poly-Si electrodes are flanked on both sides by Al electrodes which are alternately connected together to form interdigitated two-phase control lines. The output ends of the charge transfer paths are provided with P + type diffused drain regions 22 contacted by an Al output electrode 24. The first Al control conductors of all the paths are connected together to a # 1  supply, the second Al control conductors of each path are selectively connected to a # 2  supply by means of FET switches under control of a ring counter, and the poly-Si electrodes are connected together to a fixed bias supply V 0 . In operation light incident on the substrate through transparent thin portions of the oxide layer and poly-Si electrodes generates electronhole pairs and the minority carriers (holes) accumulate in the potential wells generated below the poly-Si electrodes. If only the # 1  pulses are applied the stored charges move into the deeper potential wells formed during the negative excursions but return to their original positions between pulses so that no net shift is achieved. The lines are read out in sequence by selectively enabling the # 2  supply. The # 1  and # 2  pulses are shaped and phased so that the stored charges are shifted step by step up to the drain region which is negatively biased so that it receives the charge packets and causes a corresponding current to flow in an external resistor forming the input of a sense amplifier. Illumination of the storage cells while they are being read-out has little effect on the output since the read-out time of a line is much shorter than the time during which the charge is accumulated during the scanning of the other lines. A shift register, Figs. 6 to 8 (not shown), comprises alternate poly-Si and Al electrodes arranged so that alternate poly-Si electrodes are connected to a fixed bias supply V 0 , the remaining poly-Si electrodes being connected to their adjacent preceding Al electrodes and to the # 2  supply and the remaining Al electrodes being connected to the # 1  supply. In this arrangement charge storage occurs below alternate poly-Si electrodes. This arrangement may also be used as an image pick-up device.

Abstract: 347,732. Making valves. GRAY, T. F., BOLTON, E. A., and VICTORY VALVES, Ltd., Adswood, Stockport, Cheshire. Jan. 4, 1930, No. 414. [Classes 83 (ii) and 83 (iv).] Perforating and dividing by fusion.-Highpressure steam or hydraulic valve bodies of large size are produced from forgings by combined processes of machining and flame cutting from machined holes by oxy-acetylene or other flame. For a parallel slide valve, as shown in Figs. 4 and 10, a forging of a plain cube-like form is first shaped exteriorly by flame cutting, and thereafter a hole d of small diameter is drilled through the cylindrical part of the block. This hole is enlarged by flame cutting to form the passages e. The valve chamber f and opening g are subsequently formed by flame cutting, and the body brought to the finished flanged form, as shown, by flame cutting and machining as required. The production of other forms of valve, as for example the screw-down valve shown in Fig. 37, are described making use of the same general method. In some of these casings apertures such as v, for access to the valve members are formed and are closed by interior covers s secured by outer plates y and bolts u. Specification 346,286, [Group, XXIX], is referred to.
