Filed: 1973-03-09
Abstract: 1419693 Electrographic process RICOH K K 9 March 1973 [13 March 1972] 11484/73 Heading G2H A multi-coloured image is produced by forming an electrostatic latent image on a dielectric layer of an electrostatic recording sheet using electric signals, e.g. facsimile transmission, the dielectric layer containing a photo-conductive substance, developing the electrostatic latent image with a colour toner, exposing the dielectric layer to actinic radiation, forming a further electrostatic latent image on the dielectric layer, and developing the further latent image with a further colour toner. In an example, the recording sheet was a conductive paper sheet coated with a mixture of a butyl acrylate/methyl methacrylate copolymer and zinc oxide. Three successive latent images were produced by subjecting the sheet to a known (unspecified) electrostatic recording process with intervening development of each latent image with yellow, magenta and cyan toners respectively, the residual charge remaining after the first two development stages being completely removed by exposure to white light from a tungsten lamp before forming the second and third latent images respectively.

Abstract: 1,169,817. Control systems for incandescent lamps. BROWN, BOVERI & CIE A.G. 13 March, 1967 [2 April, 19661, No. 11595/67. Heading H2H. [Also in Division H3] In order to prevent overheating of a circuit including an incandescent lamp 5, the power supply to the lamp is controlled by means including a bi-directional semi-conductor device 1 and a temperature variable resistor 10. The resistor 10 is situated so as to be responsive to the components in the circuit and is electrically connected in a bridge network comprising a variable resistor 11. The output of the bridge charges a capacitor 8 until such time as a second bi-directional semi-conductor device breaks down, whereupon the capacitor 8 discharges through the winding 4 of a so-called pulse transformer to cause a short, high amplitude pulse to be developed in the winding 2 of the transformer. The device 1 thereupon breaks down to pass current to the lamp 5, the period of conduction of the device 1 in a cycle being determined by the setting of resistor 11 and the resistance of the temperature sensitive resistor 10. If desired, the resistor 10 may be replaced by a similar serially connected resistor 9.

Title: Improvements in and relating to reactive electrical equipment, commonly termed reactors, more particularly for the purpose of automatically controlling and/or limiting the flow of energy in electrical circuits
IPC: H02H9/02
Filed: 1933-04-21
Abstract: 421,467. Transformers; protective arrangements. MACKAY, T. W., Pentland, Barton Cross, Torquay, and KNOWLES, H. A., Lochnagar, Torquay Road, Kingskerswell, Newton Abbott, both in Devon. April 21, 1933, Nos. 11643/33 and 8256/34. [Classes 38 (ii) and 38 (iv)] [See also Group XXXVI] A reactor comprises a plurality of windings so related that normally they give a negligible reactance, but give an increased reactance on the actuation of an interrupter as the result of an overload. As shown in Fig. 1, a main winding a and an auxiliary winding bare arranged on a core d so as to be magnetically in opposition. The windings a, b are connected in parallel, a fuse or grid-controlled arc circuit interrupting device f being connected in series with the auxiliary winding b. A third winding c has induced in it a small electromotive force which may be employed for calibrating and adjusting the reactance or for operating switch tripping mechanism, alarm circuits &c. without the use of relays. The windings may alternatively be arranged as shown in Fig. 2, the auxiliary winding b being divided into three parts so arranged that their magnetomotive forces are equal and in the same direction in each limb and the resultant fluxes neutralize the flux due to the main winding a on the centre limb. According to the first Provisional Specification, an additional reactance winding having a separately excited magnetic circuit may be employed instead of or in conjunction with the fuse or interrupter f. This may be connected across the contacts of the switch or fuse for controlling the time constant of the main reactor. Alternatively, the operation of the additional reactance may be made automatic and independent of a switch or fuse by associating it with a unidirectional magnetic field which is capable of varying the impedance of the circuit, the field being proportional to the load current. The unidirectional field may be obtained from two current transformers in the main circuit, the secondary windings being interconnected or connected to a summation transformer supplying a rectifier circuit. One of the current transformers has an output following a straight line law and the other has a characteristic saturation curve, the resultant output being the difference of these outputs.

Abstract: 1,247,122. Sound source locating. SPERRY RAND CORP. 11 March, 1970 [12 March, 1969], No. 11702/70. Heading H4D. In a sound-monitoring system for installation on a ship, e.g. to detect other vessels in the ship's path, primary receiving means are responsive to sounds from one or more specified regions of interest, auxiliary receiving means are responsive to sounds from another region, signals from all receiving means are subjected to amplification with automatic gain control (AGC), reference signals each representing the long-term average of signal amplitude for a respective region are derived, and an alarm indicates if such a reference signal is momentarily exceeded by signals from a said region of interest. In the Fig. 1 system microphones 15, 13 detect sounds from port and starboard regions P, S of interest and sound aft (region A) is detected by microphone 17. The microphone outputs are multiplexed at 21, amplified at 27, de-multiplexed at 29 and routed to appropriate channels P, A, S. The P, A and S signals are summed at 31 to provide an AGC control signal. The AGC time constants are such that a momentary gain change prevents amplifier saturation and persists for at least one multiplex sampling cycle, whereby a burst of sound actuating any microphone gives a signal which passes through amplifier 27 without significant distortion but with essentially the same gain as corresponding signals from the other microphones. This ensures that spurious pick-up, e.g. by microphone 13 or 15 of sounds from region A, does not actuate the alarm. In each channel the long-term average amplitude is derived at 37 and any signal exceeding this by some threshold amount in the P or S channel actuates an alarm 39. The channel outputs at 37 are fed to a cathode-ray tube readout 41 giving a Y pattern display, or to a magnetic recorder. Switch system 45 enables selected ones of the P, A and S signals to be monitored on a loud-speaker or headphones 43, and enables calibrated delays to be inserted in the signal channels for determining the bearing if a sound source.

Abstract: 266,939. Bouzin, O. May 4, 1926. Rotary kilns.-A rotary kiln for treating cement &c. is formed in-. ternally with annular projections 21, which are spaced apart a distance at least equal to the diameter of the kiln, so as to cause the material to spread along a succession of substantially horizontal planes. In the apparatus shown the kiln proper discharges into a cooler 20, and at the air inlet end of this cooler, and at the gas outlet end of the kiln, are metal heat exchangers, each consisting of a central tube 22 spaced from the kiln by radial plates or partitions 23. At the inlet end of the kiln these plates project beyond the tube 22 and are curved so as to carry the charge into the peripheral compartments, while the heating-gases pass through the tube. In a modification a number of small tubes is employed instead of a single large tube such as 22. The supply of air to the cooler is limited to the amount necessary for combustion in the kiln by a register at the outlet, or by a disc 33 and an annular plate 34.

Abstract: 1,222,794. Automatic exchange systems. SIEMENS A.G. 6 March, 1969 [7 March, 1968], No. 11907/69. Heading H4K. Scanning for line conditions proceeds over subscribers' line circuit groups (such as TG1) and other exchange circuits (such as own and other exchange relay sets HUe and AUe, and operators' relay sets VPl), each group of line circuits and each other exchange circuit having an associated row of a scanning matrix store SpMa, one element of each row indicating the state of the group of line circuits or the state of the other exchange circuit, a row scanner AE1 examining the state elements of each row of the matrix in synchronism with a scan of the corresponding line circuit groups and other circuits, a column scanner AE2 automatically ensuring that the columns containing the state elements are selected during such scanning. The matrix SpMa may consist of a number of planes so as to provide a multi-bit storage capacity for each element of the matrix; ferrite cores being employed as storage elements. The line circuit groups TG have a common intermediate store TZS, comprised of ferrite cores, on which is set up in parallel the states of the individual subscriber lines. An OR-function establishes a group state if any one or more of the lines is in the active state. The corresponding scanning matrix row has an element for each line of the group and an additional element, in column n, to indicate the group state, as last scanned. The first column of each row corresponding to another exchange circuit (Hlle Alle, VPl) records the circuit state. For each scanning position of the row scanner AE1 the state data from the last scan as recorded in the matrix is read out to register ZR2 while the corresponding current data from the circuits themselves is recorded in the register ZR1. A logic circuit ZO determines from a comparison of current and last look data what, if any, action is required by the central control circuit ZeSt, such action being implemented and the matrix store brought up to date before the scanner proceeds to the next row. If the group state data indicates activity requiring attention in a line circuit group, the scanner Ae2 steps over the elements of the intermediate store TZS and the corresponding elements in the associated matrix row so that the states of the individual lines are compared with the last look data in ZO with ZeSt reacting accordingly. The scanner Ae2 has a section 5 said to be employed for route finding.

Abstract: 238,293. Duvieusart, F. May 14, 1924. Engines working on special systems or cycles; vapour engines.- In a closed-cycle engine, water or other working substance is caused to pass through a semipermeable membrane, through which a solute dissolved in the water &c. cannot pass, the water &c. after passing through the membrane being evaporated, allowed to expand to perform work, and finally condensed into the solution. The membrane D, Fig. 1, divides a receptacle into two chambers A, B, the solution being in the chamber A, and the water or other solvent passing through the membrane into the chamber B. The receptacle, is immersed in a bath R at a temperature between the boiling point of the solvent and that of the solution, and steam or vapour from the chamber B bubbles intermittently through mercury in a U-tube S, passes to means for performing work, and is condensed and returned at atmospheric pressure to the chamber A. The solution may consist of glucose in water, the membrane D being of cellulose impregnated with copper ferrocyanide. In a modification, the solution is only partly separated by the membrane, the solute passing through more slowly than the solvent, e.g. a solution of alcohol in ether, for which a membrane of vulcanized caoutchouc may be employed. A series of chambers containing such membranes may be employed in this case, the separation of the solvent from the solute thus being effected in stages.

Filed: 1942-08-27
Abstract: 559,703. Fuel injection pumps. BENDIX AVIATION CORPORATION. Aug. 27, 1942, No. 12094. Convention date, Sept. 20, 1941. [Class 102 (i)] In a fuel injection pump in which a delivery valve controls the flow of fuel between a pressure chamber and a delivery chamber and also controls byepass passages for connecting both these chambers to a region of lower pressure, the byepass passages terminate in the seating of the delivery valve and are cut off when the delivery valve is seated. In the form shown, a plunger 19 angularly adjusted by a rack 20 and formed with helical, annular, and axial grooves 26, 28, 29, is reciprocated in a cylinder 11 formed with inlet and byepass ports 16, 17 and with a passage 30. The cylinder 11 is aligned with an adaptor 12 having a conical seat 22 upon which the head 21b of a valve 21 is pressed by a spring 23 guided by a member 24 serving also to limit the lift of the valve 21. The latter is formed with central and diametrical passages 35, 36, whilst the adaptor is formed with annular grooves 27, 31, 33 connected to passage 30 by passages 32, 34. Groove 29 is of sufficient size to be in constant connection with passage 30 for all positions of the plunger 19. When the latter is raised, port 16 is closed, pressure in the pump chamber is built up, and valve 21 is raised until passage 36 overlaps groove 27 to begin delivery. When groove 26 overlaps port 17, delivery is cut off, and when the plunger 19 reaches its top-deadcentre, valve 21 gently closes on its seating 22. The delivery pressure is thereby reduced, dribbling at the injection nozzle is prevented, and pressure surges in the delivery line are damped. Grooves 27, 28 may be replaced, respectively, by a series of ports and a diametrical passage, and the provision of the groove 27 and passages 35, 36 may be avoided by using a valve with a fluted stem.
