Title: Improvements relating to automatic voltage control systems
Inventor: ASBURY ALLAN
IPC: H02P5/69
Filed: 1954-01-05
Abstract: 739,506. Automatic speed control systems, ENGLISH ELECTRIC CO., Ltd. Jan. 5. 1954, No. 265/54. Class 38 (4). In an automatic control system for three D.C. generators G1, G2, G3, connected in a closed series load circuit with the armatures of three mechanically connected, separately excited, D.C. motors M1, M2, M3 of one stand of a tandem mill, the motor armatures and the generator armatures being arranged alternately round the load-circuit, the excitation of all three generators is simultaneously automatically varied in order to maintain the mean generator voltage constant. The fields G1f, G2f, G3f of the generators are connected in parallel with each other through individual field rheostats VR1, VR2, VR3 respectively and the paralleled circuits are connected in series with the output side of an amplifying exciter AE across the mill reference bus-bars RB. The input side of the exciter is connected across the reference busbars through three similar parallel circuits, each including a resistor, e.g. R1a, the armature of one generator, e.g. G1, and a second resistor, e.g. R1. The input signal is thus the bus-bar voltage minus the average of the three armature voltages. It is stated that the amplifying exciter may be replaced by either a magnetic amplifier or an electronic amplifier.

Title: Marine autopilot systems
IPC: G05B11/42
Filed: 1974-01-03
Abstract: 1451253 Automatic control TOKYO KEIKI KK 3 Jan 1974 [10 Jan 1973] 00287/74 Heading G3N In a marine autopilot 14 wherein the actual heading of a ship 12 is measured by a sensor 13 producing a signal # which is compared with a command signal #i and a resultant error signal is fed to a closed loop servo system which controls the angle # of a rudder 11, the rudder control loop incorporates a P.I.D. control unit 5 and the capacitor C I  which performs the integrating function therein is bridged by a non-linear circuit Z, Fig. 5, to protect the capacitor and limit the integrated value of the rudder angle. The constant rudder angle which the system may set to compensate for side wind or ship geometry is thus limited, which avoids this angle being set to a value near the rudder operating limits for the autopilot. The rudder control loop comprises an amplifier 1, hysteresis relay 2 to give relay servo operation, and a servomotor 3 which sets the rudder angle via gearing 10. This angle is sensed by a potentiometer 4 so that an electrical feedback signal is passed via the unit 5 to comparator 7'. The non-linear circuit Z may have several forms Figs. 6A-C (not shown) using diodes or Zener diodes.

Abstract: 545,131. Indicating-apparatus. LISTER, H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 9, 1941, No. 328. Addition to 494,017. [Class 106 (iv)] [Also in Group XXXVI] In the instrument mounting means claimed in the parent Specification, the cylindrical portion of the bezel and the clamping ring are provided with cooperating abutment surfaces and the ring carries means by which the instrument may be rigidly clamped thereto from its rear end. The split cylindrical portion 5 of the bezel 4 is provided with a number of circularly distributed abutments 5a formed by sheared and pressed-out tongues, so that the clamping-ring 8 engages them when forced rearwardly by turning the screws 12, which pass through threaded holes in brackets 11 on the clamping-ring 8 and carry pads 13 pressing against the back of the panel 1. The screws 12 are extended and pass through unthreaded holes in the normal fixing lugs 7a on the base plate 7 of the instrument. The screwed rods 12 have central hexagon portions 12b and are provided with nuts 12c engaging each side of the lugs 7a. The axial-direction clamping means may be separate from the means by which the clamping ring is pushed away 'from the back of the panel. The clamping and pushing screws may be replaced by cams, &c. The axial-direction clamping screws may be replaced by angle bars each of which is secured or hinged at one end to the clamping ring whilst the other end has its angle portion passing behind the back plate of the instrument and provided with screws or cams.

Title: Improvements relating to antenna systems
IPC: G01S1/02
Filed: 1942-01-12
Abstract: 570,201. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., and ARMSTRONG, L. J. HEATON-. Jan. 12, 1942, No. 417. [Class 40 (v)] An antenna system, of the kind defining an approach path by means of overlapping beams produced by oscillating the radiation pattern about the approach path by reflector antennt rendered alternately effective, comprises two or more directly-fed antennae O1, 02 arranged to produce a greater field strength in the direction of the reflector antennµ 1, 2, which are on either side of the approach path and on a line perpendicular to it, than in the direction of the approach path itself. By adjusting the distances d1, d2 between the fed and the reflector antennae respectively, the field strength along the approach path may be rendered the same when either reflector is operating as in the change-over period when both are momentarily out of action, thus avoiding key-clicks, and at the same time a beam of minimum width may be obtained. The antennµ O1, 02 are fed with in-phase currents. More than two fed antennµ may be employed.

Title: Improvements in or relating to filters
IPC: B01D33/00
Filed: 1930-01-06
Abstract: 352,038. Filters. MILLER, T. F., 2, Risebridge Road, Gidea Park, Essex. Jan. 6, 1930, Nos. 521 and 6423. [Class 46.] Edge filters are formed by winding spirally strips as shown in Fig. 9, provided with apertures 6 and protuberances 2. The elements are mounted on a central tube 8, Fig. 1, having perforations 9 corresponding to the passages in the elements formed by the apertures 6. These passages are closed at their outer end, the outer turn of the spiral being imperforate. Liquid supplied to the casing 1 through an inlet 13 passes inwardly through the elements and is discharged through an outlet 14. The apertures 6 may be nearer one edge of the strip and adjacent turns of the spiral may be formed of strips having their wider margins turned in opposite directions, as shown in Fig. 1, so that grooves of rectangular cross section are formed on the faces of the element, which grooves serve to retain filter aid in position, if filter aid is used. A similar effect is obtained by using strips of different widths for adjacent turns of the spiral. As shown in Fig. 3, the filter element is conical, and a perforated screen or wire gauze 15 is provided below the downwardly turned surface to aid in retaining the filter aid on the face of the element. Similar screens may be provided if the faces of the element are arranged vertically. As shown in Fig. 6, elements 1 are mounted on an axis which can be rotated by gear 19. Scrapers 21, 22 are fixed to the casing to remove accumulated solid matter from the faces of the elements or from the screens 15, if the latter are provided. The elements may be cleansed by fluid from sprays 20.

Filed: 1971-01-07
Abstract: 1337301 Treating waste material ENVIRONMENTAL SCIENCES Inc 7 Jan 1971 [8 Jan 1970] 802/71 Heading C1C [Also in Divisions C3 and E1] A method of treating a waste material of industrial or domestic origin containing a silicate setting agent comprises mixing said material with an alkali metal silicate in proportions such that the depositing mixture is converted to a hard solid. In one embodiment of the method the waste material is mixed with an aqueous solution of an alkali metal silicate and a silicate setting agent. Typical wastes are garbage, solid industrial wastes, packaging materials, plastics, glass, sludges, slag, chemical process by-products, and oily materials. The setting agent may be calcium chloride, calcium sulphate or polyvalent heavy metal salts. The method finds application in treating land of little practical use wherein the waste material is subdivided, thereafter mixed with an aqueous solution of an alkali metal silicate and with a silicate setting agent, and then deposited on the land surface, thus producing a consolidated material. Specific examples refer to the treatment of (1) household refuse to which calcium chloride has been added; (2) acid mine sludge; (3) a sulphuric acid pickle liquor; and (4) a chemical plant waste.
