Title: Gravity separation of solids
IPC: B03B5/30
Filed: 1958-09-15
Abstract: 874,755. Magnetic separators; washing granular materials. MINERAL PROCESSING CORPORATION. Sept. 15, 1958 [Sept. 19, 1957], No. 29509/58. Classes 82(2) and 117.  In gravity separating a mixture of non- magnetic solids, e.g. anthracite coal having a S.G. less than 1.7 and refuse having a somewhat higher S.G., the mixture comprising particles less than 3/64 inch is introduced at 11 into a settling tank 10 containing a separating medium of magnetite and water, the medium having a S.G. less than either the coal or the refuse. Separating medium is introduced into the tank at 12, 16 at rates such that an upward current 15 is produced in the tank and causes the float fraction, consisting of coal particles and some medium, to pass over a weir into a box 20 to which water is added, the fraction being passed to a magnetic separator 22 from which the coal and most of the water issues at 30. The magnetite from this separator and from a further magnetic separator 28 passes into a mechanical agitator 35 from where it is passed into a reservoir 39. The sink fraction, comprising refuse and magnetite, is treated by the separator 28 and passes from an orifice 14 in the tank 10 via a dilution box 26, the refuse water fraction being collected at 31. The appropriate amount of water is restored to the medium in the reservoir 39 and the medium re-circulated by a pump 41. The magnetic separators may be of the belt, drum or revolving field type and they may be excited by A.C. or D.C. or by permanent magnets. Ferro silicon and iron alloy are also specified for the separating medium and a demagnetizing coil may be used in place of the mechanical agitator. Either the float or the sink fractions may be further treated in another separating vessel to obtain an intermediate or a third product.

Patent GB-473807-A (GB)
Title: Improvements in or relating to radio directing and direction finding systems
IPC: G01S1/02
Filed: 1936-10-30
Abstract: 473,807. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1936, No. 29555. Convention date, Dec. 31, 1935. [Class 40 (v)] In a radio-navigational system, particularly for aircraft, signals of the same wavelength are used both for the guide-line to the aerodrome and for the landing beam, the different signals being successively transmitted for a predetermined time. As shown in Fig. 7, the two reflecting dipoles 4, 5 are keyed alternately to produce the usual overlapping-beam which indicates the direction of the aerodrome, the upper dipole reflector 12 then being open. When both 4 and 5 are open, and 12 is closed, a landing-beam of the form shown in full lines in Fig. 5 is radiated. In order to advance the landing point well in front of the beacon P, as shown in dotted lines, the upper dipole 12 is inclined as shown in Fig. 6. The times of the two types of transmission may be equal, or they may be repeated periodically at any desired frequency. A comparison of the strength of the two received signals will indicate to the aviator his distance from the aerodrome, thus rendering the use of marker beacons unnecessary. Fig. 8 shows the receiving equipment on the aeroplane. The signals are separated by filters 17, 18, 19, the neon lamps 21, 22 indicating the overlapping-beam course. A constant level in the third neon lamp will bring the aviator down the landing beam. A direct-current zero-centre indicator 20 may also be fed through rectifiers R1, R2 from the filters. In the Specification as open to inspection under Sect. 91, three reflector dipoles are arranged above the aerials 1, 4, 5 of Fig. 7, to provide a landing beam at short range. The use of infra-red radiation instead of wireless waves is also suggested. This subject-matter does not appear in the Specification as accepted.

Abstract: 650,106. Television. RADIO CORPORATION OF AMERICA. Nov. 6, 1947, No. 29624. Convention date, Dec. 14, 1946. [Class 40 (iii)] In a colour television system in which a scanning raster produced on the fluorescent screen of a cathode-ray tube is employed to scan a colour transparency, the scanning light which is transmitted through the transparency is divided up into component colour rays, each of which is utilized to generate corresponding electrical signals. In the arrangement shown in Fig. 3, light from a luminous raster traced on the fluorescent screen of a cathode-ray tube (not shown) which is transmitted through the image to be televised (e.g. a transparency) 31, is directed on to photo-electric cells 41, 43, 49 through colour-selective filters 39, 41a, 47 by means of a first colour-selective reflector (e.g. a dichroic mirror) 35 which reflects red-green light and transmits blue-green light and a second colour-selective reflector 45 which reflects the green and transmits the red of the incident redgreen light, the blue-green light transmitted by 35 being directed on to photo-electric cell 41 and blue filter 39 by reflection at a half-silvered mirror 37 and on to photo-electric cell 43 and green filter 41a by transmission through 37. The green light which is reflected by selective reflector 45 is also directed on to the photoelectric cell 43 by reflection at a mirror 51 and at the half-silvered mirror 37, the part which is transmitted through 37 being filtered out by blue filter 39. In another arrangement (Fig. 4), light from the image is directed on to a three reflective-sided pyramid 61 which divides the incident light into three separate rays corresponding respectively to the three colourchannels comprised of photo-electric cells 63, 65, 67 and their associated colour-filters 69, 71, 73, respectively. In a further arrangement (Fig. 5) light from the image 83 is divided into its component colours by means of a prism 851 and the emergent rays are directed on to photo-electric cells 95, 97, 99, through colour filters 89, 91, 93, respectively. An arrangement in which the light from the image is divided into three beams, each of which is directed on to a photo-electric cell and corresponding colourfilter means of two half-silvered mirrors is described with reference to Fig. 1 (not shown).

Title: Electric interface unit
IPC: H04Q3/545
Filed: 1970-06-19
Abstract: 1275210 Automatic exchange systems INTERNATIONAL BUSINESS MACHINES CORP 19 June 1970 [20 June 1969] 29789/70 Heading H4K  An interface 1 between a computer 3 and a plurality of junctors 2 each of which includes a plurality of relays, n1-n8 comprises a store 5 having one cell m1-m8 in respect of each of the relays in a junctor and a number of cells t, r in respect of a control word which is operative on all those m cells that may be concurrently marked. The control word may be 11 meaning complete updating of the junctor, 10 meaning the setting of some relays, 01 meaning the resetting of some relays or 00 meaning that the condition of the relays should be transmitted to the computer.  In operation the computer starts the interface clock counter 10 over lead D and writes a word into store 5. The parity (bit P) is immediately checked in circuit 11 whereby fault detector 12 is enabled to signal the computer on lead F if there is any fault. The counter is stopped and the contents of store 5 are transmitted to the computer which thereafter resets the counter. If there is no fault, the address in x 1  ... y 3  of the required junctor is decoded at 6 and the interface thereby connected via contacts J1-J8 to the relevant junctor. During time phase t2 the contents of t-m8 are decoded in circuits 7 of which there is one per relay in a junctor. For example, with the control word 11, a 1 bit in m1 causes transistor driver 17 to apply negative battery to output lead 19 thus energizing relay n1 in the junctor, on the other hand if m1 contains a 0 bit transistor driver 18 applies a small positive battery via a Zener diode (Fig. 2, not shown) to lead 19 thus releasing n1. Similarly for each of the cells m2-m8. With control words 01 and 10 only 1 bits in m produce a significant result. The effect of control word 00 is mentioned below. During phase t3 the circuits 7 are cut-off while circuits 22 (which incorporate transistors and Zener diodes, Fig. 3, not shown) measure the potentials on their associated leads 19. The potentials are compared with the control word and the m bits so as to produce a fault output via fault detector 12 if the relevant n relays have not operated correctly. If the control word is 00 circuits 26-28 are enabled during t3 to convey the conditions of the n relays (as determined by the potentials measured on leads 19) to the store 5. The fault detector is enabled (via circuit 49) by control word 00 so as to call in the computer but as there is no real fault i.e. leads 44, 48 are not marked, the computer knows that it is merely being informed of the n relay conditions in the defined junctor. The counter is reset by the computer as before. For other control words under no fault conditions, the counter rests itself at t5, having cleared all the stores during t4. Bi-stables are used as the cells in store 5.

Title: Improvements in automatic adjusting devices for brakes, clutches and the like
Inventor: BUTLER HENRY JAMES
IPC: F16D65/18
Filed: 1955-10-20
Abstract: 812,003. Automatic brake - adjusting mechanism. DUNLOP RUBBER CO. Ltd. Sept. 25, 1956 [Oct. 25, 1955], No. 29937/55. Class 103 (1). [Also in Group XXIV] In a wear adjustment mechanism for vehicle brakes, clutches and the like of the kind comprising a rotatable member and a friction member axially movable to engage the rotatable member, a pin has one end slidably associated with an applying mechanism and its other end slidably movable between two fixed stops such that the pin is engaged by a slidable stop adapted to move relatively to the pin, in the form of a close coiled helical spring engaging the pin with a predetermined degree of interference, such that on continued movement of the mechanism in excess of a restricted distance defined by the fixed stops when the mechanism is operated, compensates for wear of the friction member. In the " spot type " disc brake illustrated, a pin 19 is provided with a head 18 housed between two fixed stops dehned by a cap member 21 and a recess in tne cylinder head 15 respectively. The shank of the pin 19 extends into a recess 23 in the piston 11 and is frictionally gripped with a predetermined degree of interference by a close coiled helical spring 25 fluid pressure in recess 13 forces piston 11 axially in bore 16 of cylinder 12 and forces friction pad into frictional engagement with a rotatable brake disc 1. During this movement the pin 19 is carried with the piston by the interference caused by the helical spring 25 and the head 18 of the pin is drawn axially of the space 22 in the recess 17 to compress Belleville spring 20. Should friction pad wear cause the spring 20 to be fully compressed, continued axial movement of the piston 11 towards the disc 1 will cause helical spring 25 to be drawn axially along the pin to compensate for wear of the friction pad. Upon release of the fluid pressure from the space 13 the resilient annulus 10 which also acts as a dust seal will retract the pad 2 from the disc 1 and the piston 11 will move axially in the bore 16, carrying with it the pin 19, until the head 18 of the pin abuts the base of the recess 17 and the friction pad 2 will be withdrawn from the disc by a distance only equalling the axial depth of the space 22. A further embodiment is disclosed in the Provisional Specification. Specifications 738,034 and 747,972 are referred to.
