Title: Improvements in radio antenna systems
IPC: G01S1/02
Filed: 1944-03-30
Abstract: 594,768. Directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 30, 1944, No. 5934. Convention date, March 31,1943. [Class 40 (v)] An antenna system comprises four coplanar radiator elements extending from a common centre, adjacent elements being at right angles to each other, together with a fifth radiator element extending from said common centre at a right angle to said common plane and means for constantly energizing the fifth element and selectively energizing collinear pairs of the other elements. The four elements 5, 7, 9, 11 of approximately “# comprise inner conductors 13 connected to the outer conductor of the line 1 having a radiating element 3 of approximately “ # and outer conductors 13<1> connected to the inner members 13 by plugs 15. The outer conductors 13<1> are also connected to the inner conductors of transmission line 17, 19, 21, 23, the outer conductors of which are connected to the outer conductor of line 1 by a disc member 2. Lines 17, 21 are connected to a transmission line 27 at a point 25 which is “ # farther from element 5 than from element 9 and the line 27 includes a ¢# section 29 which can be short-circuited by a switch 33. The junction 35 of lines 19, 23 is ¢ # farther from the element 11 than from element 7 and transmission line 37 incorporates a switch 43 and a ¢ #section 39. The length of line between elements 5, 9 and between elements 7, 11 is any odd number of half wavelengths. The switches 33, 43 are connected to lines 31, 41 associated with a double throw switch 45 and a line 47 leading to a radio transmitting or receiving device. The switches 33, 43, 45 are ganged for operation in a desired sequence by a motor 46, and a power division network may be provided between line 47, line 1 and switch 45 to provide appropriate ratio of energy applied to element 3 and to radiators 5, 7, 9, 11. The total length of line between switch 45 and each of the elements 5, 7, 9, 11 is an odd number of quarter wavelengths. The antenna assembly is combined with a parabolic reflector 24 so that the elements 5, 7, 9, 11 lie at its focal plane. When the switch 43 is open and the switch 45 in its left-hand position, connecting the dipole 5, 9 to the high-frequency source, the switch 33 in its open and closed position provides a radiation pattern with maximum field on opposite sides of the axis of the element 3 and in the plane of the elements 3, 5, 9, whilst with switch 45 in the opposite position, elements 7, 11 provide two further patterns with the directions of maximum radiation in the plane of the elements 3, 7, 11. A fifth lobe, centred on the axis of the array, is obtained by opening switches 33 and 43 simultaneously.

Patent GB-557168-A (GB)
Title: An improved telemetering installation
IPC: G08C19/02
Filed: 1942-05-04
Abstract: 557,168. Electric signalling systems. LANDIS & GYR SOC. ANON. May 4, 1942, No. 5960. Convention date, May 5, 1941. [Class 40 (i)] In a system particularly for indicating remotely the load of an electrical consumer's network, any increase or decrease in the speed of rotation of a progressive meter causes the transmission of impulses of one kind or another until a steady speed is reached. The sunwheels 9, 13 of a differential 8 are driven respectively by auxiliary motors 23, 24 to follow the rotation of the meter 1 and that of a comparison meter 2 so that any difference of speed produces a movement of the planetwheel shaft 17 which adjusts a potentiometer 4 in circuit with the meter 2 until a fresh balance is obtained. At the same time the shaft 17 drives a commutator 27 or 28 according to its direction of movement to transmit impulses of current of one frequency or another. At the receiving station, the impulses operate tuned relays 40, 41 which control the movement of a shaft 17<SP>1</SP> through escapements 33, 34, the shaft being driven in either direction by motors 23<SP>1</SP>, 24<SP>1</SP> through a differential 8<SP>1</SP>. The shaft 17<SP>1</SP> carries a pointer 44 and also controls a potentiometer 4<SP>1</SP> in circuit with a progressive meter 2<SP>1</SP> similar to 2 at the sending station. If it is desired to transmit the volt-ampere load, the active and reactive components are sent independently to meters at the receiving station, the readings of which are combined by the use of suitable differential gearing. Moreover, the readings received from a number of sending stations may be integrated by means of several sets of differential gearing. An induction regulator may be employed instead of a potentiometer for adjusting the speed of the meters 2, 2<SP>1</SP>.

At starting, compressed air can pass from the top of the container 1 to the bore 6 through a valvecontrolled pipe and a metering jet so as to atomize the fuel issuing from the jet 9 and render it combustible.
Patent GB-777234-A (GB)
Title: Boron nitride shapes and method of making
IPC: C04B35/583
Filed: 1955-03-02
Abstract: A boron nitride body stable to water and alcohol is produced by hot-moulding a mixture of boron nitride to a stabilizer which forms with boric oxide under the conditions of moulding a material which is substantially, insoluble in water and alcohol and which is an alkaline earth compound other than tricalcium phosphate or a mixture of such compounds and/or a rare earth compound or a mixture of such compounds.  The proportion of stabilizer may be up to 10 per cent. Stabilizers specified are calcium, barium, strontium and magnesium, carbonate, sulphate and oxide.  The boron nitride may have a particle size not exceeding 0.5 microns. The material may be hot pressed at a temperature of 1500-1900 DEG C. under a pressure of 400 psi or more. The resulting body may have a sand blast penetration not less than that of plate glass, an apparent density of not less than 1.9 gm./c.c. and an alcohol-soluble content, calculated as B2O3, of less than 10 per cent.  The boron nitride to be hot pressed may be produced by heating boric oxide in an atmosphere of ammonia at a temperature of 800-1100 DEG C. in the presence of an acid soluble inert diluent which is tricalcium phosphate or a stabilizer as defined above.  It may alternatively be produced by heating a mixture of boric oxide with previously formed boron nitride at a temperature of 800-1100 DEG C. in an atmosphere of ammonia.

Title: Improvements in and relating to filters
IPC: B01D15/00
Filed: 1953-03-20
Abstract: 756,735. Filters; purifying liquids; ionexchange. KRETZSCHMAR, A. March 20, 1953, No. 6199/53. Class 46. A cylindrical vessel, of open or closed construction and containing a particulate mass of gravel, or of acid-, iron- or manganese-removing material, or of ion-exchange material, has a conical member centrally and coaxially arranged within it. Expansion of the granules or of the mass as a whole is thus permitted or accelerated. In Fig. 1 filtration or treatment flow proceeds downwardly (as shown by the arrow on the left); expansion of the material 3 may occur upwards into the free space 6. During backwashing (as shown by the arrow on the right) the conicity of the member 4 permits substantial expansion so that rapid and complete discharge of impurities takes place with relatively small quantities of washing water. Used wash water passes through a bell-shaped sludge receptacle 5 and downwardly out of the filter. Regeneration, where necessary, is upward or downward. In Fig. 2 the cone 4 tapers downwardly, filtration or treatment flow is upward, and backwashing or regeneration is upward or downward. The particulate mass 3 in this case is located between filter plates 2 and 7.

Title: Sensitive d'arsonval meter-type relay mesh
Inventor: WILTON ROBERT
IPC: H01H53/015
Filed: 1959-02-23
Abstract: 861,836. Switches, partly electromagnetic. BACH-SIMPSON Ltd. Feb. 23, 1959, No. 6229/59. Class 38 (5). A relay with a D'Arsonval movement biased to extreme and normal positions by permanent magnets has a manual resetting means which applies only momentary restoring force to the movable assembly of the relay. As shown, the movement comprises coil 14 on a rotatable shaft 16, and movable in the annular space between a yoke 12 and a permanent magnet 13 which are supported on a frame 11 in the relay case 10. An arm 27 is attached to the shaft 16 and in its extreme positions moves spring contacts 33 away from contacts 32 to engage contacts 34. Current is conducted to the coil 14 by two balanced hair springs 28, 42 and the shaft 16 also carries an arm 21 with two soft iron vanes 23 equally spaced from the shaft 16. A screw 26 in a hole 24 in the yoke 12 carries a small permanent magnet 25 which co-operates with one of the vanes 23 to bias the coil assembly to the normal rest position. When the current in the coil moves the assembly in either direction from its normal position the vanes 23 are attracted by two permanent magnets 51 and the arm 27 actuates one of the contact sets 32, 33, 34 which may be in series. An extension 21a of the arm 21 carries a flag 22 which can be seen through a window 10a in the relay case. The relay is manually reset by pressing a button 53 against the bias of a spring 56 so that the legs of a U-shaped spring 57 are forced into an aperture 61a in a sliding cam so as to move it with snapaction toward the push-button 53. The cam 61 has an annular projecting ridge which, as it moves, momentarily separates the arms of two scissors elements 37, 38, pivoted on a boss 36, and their other arms move so that one of them engages the arm 21 to move it away from a magnet 51 to the normal position. Continued pressure on the button 53 will not prevent further relay operation since the cam 61 is shaped so as to impart only momentary movement to the elements 37, 38, against the bias of a torsion spring (not shown), as it moves. When the button is released a further resetting action takes place.

Title: A television receiving method employing braun tubes
IPC: H04N3/24
Filed: 1933-03-02
Abstract: 417,590. Television. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfeld-Ost, Berlin. March 2, 1933, No. 6313. Convention date, March 5, 1932. [Class 40 (iii).] In a cathode-ray receiver, the ray is extinguished during the return path to the beginning of successive pictures. The control potential, which extinguishes the ray, is derived from the potential 3, which deflects the ray from line to line of the image. The deflecting-potential is applied to a condenser 5 and resistance 6 in series, which produce a potential equivalent to the differentiation of the deflecting-potential with respect to time, Fig. 1 (not shown). Alternatively a transformer in series with a resistance may be used, Fig. 3 (not shown). The derived potential controls a rectifying- valve 7, which applies a strong negative bias to the Wehnelt cylinder 2. According to modifications, the derived potential is applied to a grid in the cathode-ray tube 1, or to a deflecting electrode near an aperture in the anode. Specification 392,383 is referred to.

Abstract: 1,128,334. Concrete slab moulding apparatus. ALEXANDER HALL & SON (CONCRETE) Ltd. 20 Dec., 1965 [13 Feb., 1965], No. 6326/65. Heading B5A. Concrete slabs are moulded in a batch of open moulds 1 comprising sheet steel side walls 2, 2A, 2B, a base 3 and end walls 4; walls 2, 2B being horizontally reciprocable. The outmost wall 2A is attached to a support structure while the base 3 and one side wall 2 of each mould rest on a pallet 5 movable horizontally of the structure on wheels 6. The side walls 2 are spaced apart by flanges 8, adjacent pairs of which are connected by " lost-motion " links 19, the flanges 8 moving on wheels 10 and rails 11. An insert (15) carries two wheels (16) which abut respectively upper and lower pairs of wedges 13, 14 on the opposed faces of walls 4 and flanges 8, the insert 15 being attached to an upper rail 17 which is raised by rams 18. The concrete mix is fed from an overhead hopper (not shown) and vibrated. When cured, the rails 17 are raised to release the walls then the rams 12 and thereby the wall 2B, are withdrawn. When the " lost-motion " is taken up by links 19, the first wall 2 moves towards rams 12. This process is successively repeated until each wall is moved to be 3 inches further from its neighbours than when assembled. The slabs are then raised, thereby raising the end walls 4. This raising is halted when the upper wedges 13 are just higher than the rail 17 and the walls are knocked outwardly to release the slabs which are then removed completely. The walls are then cleaned and re-oiled. Various modifications for raising the rails 17 and for the " lost-motion " connections of the flanges 8 are described.
