Abstract: 1418407 Bending by corrugating G A KNUDSON 14 Feb 1973 [14 Feb 1972] 7210/73 Heading B3E [Also in Divisions E1 and F2] An elongate, channel-sectioned panel 13 is arched in the longitudinal direction by passing an initially flat-sided channel-sectioned panel through a crimping machine to produce transverse corrugations in the channel's base 22 and sides 23, 24, the corrugations 31 in the sides increasing in depth towards the base 22. The crimping machine comprises upper and lower intermeshing, toothed rollers 68, 69 rotating about horizontal axes and being respectively convex and concave for corrugating the panels base and two pairs of inter-meshing toothed rollers 61, 62 and 63, 64 rotating about vertical axes for corrugating the panel's sides. Each pair of rollers 61-64 has one upwardly and one downwardly tapered roller. All of the rollers are driven from a motor M through a gear train including a clutch 81. The panel is fed initially to the rollers 61-64 which feed it to the rollers 68, 69. The rollers 68, 69 move the panel faster than the rollers 61-64 and this automatically disengages the clutch 81 so that the rollers 61-64 idle.

Title: Improvements in and relating to apparatus for tempering flat glass
IPC: C03B27/052
Filed: 1939-03-07
Abstract: 526,052. Tempering flat glass. PILKING- TON BROS., Ltd., and BIRD,' G. W. T. March 7, 1939, No. 7397. [Class 56] Relates to tempering apparatus in which a sheet of glass 4 is cooled by air blown against its surfaces from a pair of jet frames 3 that oscillate in vertical planes during the cooling- operation. According to the invention, each frame 3 carries a number of pegs 11 which can be moved simultaneously to positions close to, but normally out of contact with, the glass. The glass is not held by the pegs but is prevented from swing- ing in a direction perpendicular to its plane. The pegs slide through horizontal tubes 9 secured to the frames and are connected to cranks 12 on shaft 13 which are interconnected, so that all the pegs can be moved simultaneously by one handle. In a modified construction, the pegs are secured to the shafts 13 and swing to and from their operative position. In another construction, the position of the pegs is adjustable in a horizontal direction, and in a further construction, individual pegs can be displaced so that they are inoperative while the other pegs are in the operative position.

Title: Improvements in or relating to pressure relief valves for dense vapours
Inventor: ALLEN ERIC SIDGWICK
IPC: G07F11/04
Filed: 1954-03-16
Abstract: 760,971. Valves. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 10, 1955 [March 16, 1954], No. 7677/54. Class 135. In a valve for relieving excess pressure of dense vapours such as the refrigerant monofluor trichlormethane, a guide member 12 connected by webs 13 to the valve seat member 11 and located in this member so that its undersurface is coplanar with the seating face, shields the spring-loaded valve member 10 against direct impact of the escaping vapour. The force of the vapour acting on the valve which tends to maintain the valve member open once it is unseated is thereby reduced, so that the valve recloses at a higher pressure than would otherwise have been the case to reduce vapour losses. In a modification, the guide member periphery is formed with a knifeedge so that vapour between the guide and valve members is withdrawn by the escaping vapour to move quickly to reduce the pressure acting on the valve and ensure its more rapid closure.

Abstract: 782,357. Treatment of sewage &c. AMES CROSTA MILLS & CO., Ltd. March 15, 1955 [March 17, 1954], No. 7708/54. Class 111. In scraping and scumming apparatus for sedimentation tanks of the kind in which a floor scraper and a scum-sweep are carried by levers pivoted beneath a carriage which spans the tank and is adapted for self-propulsion longitudinally thereof, the apparatus in one direction urging sludge and scum into receivers and being raised clear of the floor and liquid surface in the other direction, the floor scraper is mounted upon the lower arms of submerged rocking levers together with one or more buoyancy chambers, one or more additional chambers being carried by the upper arms of the levers and ballasting liquid being transferable between the upper and lower chambers to depress or raise the scrapers. Longitudinal rails 14 sup. port a transverse wheeled carriage 12 on which is mounted an electric driving motor adapted, through limit switches to traverse the carriage over the length of the tank 5. Four spaced triangular frames 28 depend from the carriage to support the tubular frames 32 of rubberedged scrapers 35 which are pivoted to the frame 28 at 30. At top and bottom, the scraper frames carry buoyancy tanks 34, 33 interconnected by the tubes of the frame and connected through compressed-air lines 44, 43 to a control valve and compressor mounted on the carriage 12. One tank is filled with liquid to depress its end of the pivoted frame 32, the compressed air being directed by the control valve to transfer the liquid from the tank 33 to the tank 34 or vice versa, a neutral position of the valve locking the liquid in the filled tank. Normally the frame 50 of a scum-sweep 49 rests in its operative position on a bracket 52 on the depending frame 28 : the frame is pivoted at 51 and partly counterbalanced by a bracing 53 connected by a slack chain 54 to the top buoyancy tank 34 so that movement of the scrapers to their inoperative position lifts the sweeps to their like position. The sedimentaiton tank 5 has a collecting pit 9 at its inlet end and a floor sloping downwards thereto.

Title: Improvements in or relating to television systems
IPC: H04N7/084
Filed: 1934-03-12
Abstract: 434,882. Multiplex transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Bedford, A. V.; 118, E. Palmer Avenue, Collingswood, New Jersey, U.S.A.) March 12, 1934, No. 7790. Convention date, April 8, 1933. [Class 40 (iv)] [See also Group XL] During intervals between the scanning of successive lines in a television transmitter, a carrier is modulated by signals representing sound which occurs during the periods of scanning the lines. The sound signals are applied to a terminal 41, and the synchronizing impulses, which occur at the end of each scanning-line, are applied to a terminal 43. The synchronizing impulse is applied directly to the control grid of a valve 75, and through half and the whole of a delay network 45 to the control grids of valves 65 and 55 respectively. Each half of the network delays the impulse by À05 of the period taken to scan a line. The sound currents are applied directly to the screen grid 57 of the valve 55, and through a delay network 69 to the screen grid of the valve 55. The network delays the sound by a time approximating to half the period of scanning a line. The valves 55, 65, 75 are maintained inactive by their grid bias except when the latter is overcome by the impulse on the control grid. During each cycle, therefore, the modulating-voltage across the output resistance 63 comprises the following succession : (1) a synchronizing signal from the valve 75 ; (2) a signal from the valve 65 representing the sound during the scanning of the previous line ; (3) a signal from the valve 55 representing the sound during the fly-back time of the scanning- spot; (4) television signals from a valve 77 corresponding to the line scanned. A converse series of valves and delay networks are used at the receiver, Fig. 5 (not shown). Specifications 395,499, [Group XXXV], 434,890, and 434,891 are referred to.

Abstract: 595,691. Metal - to - glass seals. CROSSLEY, P. B., and ENFIELD ROLLING MILLS, Ltd. May 11, 1944, No. 7902/45. Divided out of 9024/44. [Class 36] Metals such as aluminium, copper, nickel, steel, tungsten, platinum, molybdenum, tellurium copper, and alloys such as brass containing a substantial proportion of zinc, are sealed to glass or like vitrefied material by means of a flux comprising a basic substantially waterinsoluble leadless hydrated metallic borate, e.g. barium, magnesium, manganese, or mixtures of such hydrated borates. One or more oxides of alkali metals such as sodium, potassium, or lithium may be embodied. The flux may be used in powder form as pellets or other preformed bodies or in the form of a water-mixed paste ; or, preferably, mixed with water to form a suspension. The stability of the suspension may be enhanced by the addition of a stabilizer such as a dispersing agent or a hydrogel. For example, 5 per cent by weight of ball-clay and/or a smaller proportion of sodium silicate may be added ; or ammonium nitrate may be employed. In forming a seal between metal and glass of materially-different expansion-coefficients, fluxes of graded expansibility may be applied successively to the metal surface. Specification 584,935 is referred to.

Title: Method of making 3-methylpyridazine
IPC: C07D237/08
Filed: 1959-03-06
Abstract: 3-Methylpyridazine is obtained by heating furfuryl alcohol with a mineral acid in the presence of a diluent, treating the crude product with hydrazine or a salt thereof, alkalising the resultant mixture and separating the 3-methylpyridazine fraction boiling at 208-216 DEG C.  The preferred diluent is a substantially anhydrous alcohol and the preferred acid hydrochloric, hydrobromic or sulphuric acid, the acid being present in a small amount compared to the furfuryl alcohol.  The process may be carried out by reacting the hydrazine or hydrazine salt with the products formed from the treatment of furfuryl alcohol with the acid while they are being produced.  The alkalising step may be carried out, for example, with an alkali metal hydroxide.

Abstract: 1484796 Actual value transmitter for a shaft QUICK-ROTAN BECKER & NOTZ KG 27 Feb 1975 [3 April 1974] 8337/75 Heading G1A Such a transmitter comprises a light source, as 34, 35, and photo-sensitive receivers 39, 40 in the beam path between which is a coding disc 23. coupled to a shaft and having an area 47 with a series of alternate light and dark areas in a circle, and a coding segment 36 with two sections 50, 51, each having light and dark areas of pitch equal to that of disc 23 but staggered with respect to each other by half the pitch, and each with a receiver 39, 40. It is suitable for positioning drives in sewing technology. Stub shaft 10 is enlarged into portion 11 for securing the end of a working shaft and journalled in housing 15 by ball bearings 14. Locating ring 16 together with shoulder 17 maintains the axial position of shaft 10 in the housing. Flanged sleeve 18 is a press fit on shaft 10. Disc 23 bears via washer 20 on flange 19 and is pinned to entraining sleeve 24 as is adjusting plate 25, against which thrust plate 26 is pressed by screw 27 in shaft 10. Circuit board 31, releasably connected to housing 15 by screw 32, carries LED 33 and at a greater radial distance LEDs 34, 35. They emit infrared. Circuit board 37 carries, besides other electronic components, receivers 38, 39, 40 axially aligned with the LED's to openings 41, 43 and 44. The receivers have rectangular photosensitive surfaces 56, 57 whose edges are at 45 degrees to the disc radius, beneath lenses 58, 59, and connected in parallel. The pitch T is the width of a pair of areas, one white, one dark. The width of the photo-sensitive area of a receiver #T. The width of a dark area is 0À6T and of a light area 0À4T. When the dark areas of the disc obscure the light areas of section 50, the light areas of the disc and of section 51 coincide to allow light transmission, conversely when section 50 passes light, section 51 does not, so that receivers 39, 40, connected to a differential amplifier, alternately receive maximum light. The r.p.m. is determined from the pulse rate produced. Dark areas 53 and 48 are radially aligned so that single light areas 54, 49 allow light to reach receiver 38 once per revolution. Area 49 may correspond to a particular angular position if the disc is so adjusted, or the angular position may be determined by a counter reset by a pulse from area 49. More annular portions with a single light area may be added. A single dark area may be used instead. Portion 48 may be an uninterrupted light area. There may be a light area between sections 50, 51 instead of a wide dark area 52. The coding disc and segment may be of acrylic glass which is photographically imprinted or has etched copper. In the embodiment of Fig. 8 (not shown), a permanent magnet (65), which can be on a separate carrier from disc 23, and Hall generator (66) replace LED 33 and receiver 38.

Abstract: 1,167,452. Luminescent materials. TEKTRONIX Inc. 21 Feb., 1968 [23 Feb., 1967], No. 8381/68. Heading C4S. [Also in Division H1]  A cathode ray storage tube of the type described in Specification 992,176 wherein a charge image is stored on a fluorescent screen, is characterized in that the phosphor particles are at least partially coated with secondary emissive material bonded to the particles so that the writing speed may be increased without reducing the brightness of the light image. The screen may be a continuous layer deposited on a tin oxide coating on the end face of the tube (Fig. 2, not shown) or may be provided with a number of holes through which secondary electrons can pass (Fig. 3, not shown). In another construction (Fig. 4, not shown) phosphor dots are disposed in the apertures of a foraminous target electrode. In one example the phosphor comprises zinc orthosilicate activated by manganese and is added to a solution of magnesium acetate dissolved in distilled water to forma slurry. The solution is heated to remove the water and produce dry particles which are fired at 700‹ C. in air for one hour to form small particles of magnesium oxide and to bond them to the surfaces of the phosphor particles. In an alternative method the phosphor particles are added to a solution of -magnesium nitrate to which ammonium carbonate is added to precipitate magnesium carbonate on to the phosphor particles. The solution is filtered and dried, and then fired as before. Alternative phosphors are zinc beryllium silicate activated by manganese; calcium tungstate activated by tungsten; magnesium silicate activated by manganese; calcium magnesium silicate activated by caesium and lithium; calcium silicate activated by manganese; and zinc phosphate activated by manganese. Alternative secondary emissive materials are aluminium oxide and beryllium oxide.
