Title: Recovery of data from magnetic wire recordings
IPC: G06K1/14
Filed: 1971-02-02
Abstract: 1385891 Data storage systems HAWKER SIDDELEY AVIATION Ltd 2 Feb 1972 [2 Feb 1971] 3728/71 Heading G4C Serial data from a magnetic wire flight recorder is supplied to an interface circuit for recording on multichannel magnetic tape which may subsequently be replayed at a higher rate. The serial input data is gated at 28 with high frequency clock pulses, and detectors 22, 23 compare the gated data, having a pulse at each transition, with ¥-bit duration pulses supplied by a divider 17 in order to derive bit clock and bit value pulses. The detected data pulses are entered in a register 48, each word assembled in the register 48 being gated out by a word pulse produced by detection at 18 of each interword gap. The input data comprises a plurality of channel words called a frame, the interframe gap being detected at 19 for gating out the contents of a frame code counter 44 which registers every fifth or tenth frame. The output channel words and frame codes are converted to NRZ and supplied to the write heads of a tape recorder. Manual switches 29 may be set to select a particular channel word for entry into a register 53 via gates 57 under control of a word counter 30. A counter 47 is then stepped by the high frequency clock pulses until the count equals the selected channel word in register 53, the number of pulses being counted and decoded at 45 for display 54 over approximately one frame period. A reference word recorded on the wire may be selected by switches 29 for comparison with a reference word set by switches into counter 47, which is then clocked in either direction to reach equality with the reference word in register 53, any error being displayed at 54. A comparator 46 produces an output to operate an audible alarm if the error exceeds a tolerance set up on switch 40.

Filed: 1973-01-25
Abstract: 1415753 Bonding fibres to rubber MONSANTO CO 25 Jan 1973 [26 Jan 1972] 3953/73 Addition to 1367362 Heading B5N [Also in Divisions D1 and C3] Fibre reinforced rubber having the fibre bonded to rubber is made by incorporating fibre, a formaldehyde donor and an adhesionenhancing amount of an essentially saturated polymer of resorcinol into a vulcanizable rubber stock and heating to form a vulcanized fibre bonded rubber product, the resorcinol polymer being obtained by condensing resorcinol with a C 3 -C 10  olefinic alcohol or a precursor thereof, e.g. allyl alcohol, allyl acetate or allyl ether, the condensation at least during the final stages being carried out under acidic conditions. The weight ratio of polymer to rubber is generally from 0À5 to 10 : 100. Suitable formaldehyde donors are hexamethylenetetramine, hexamethoxymethylmelamine, cyclotrimethyltriamines, and [(hydroxymethyl)ethylidene]- alkylamines. Suitable fibres include polyester, rayon, nylon, Al, Cu, Sn, steel, brass-plated steel, Al-steel alloy, glass, cotton, wool or wood-cellulose fibres. The fibre may be untreated or treated with RFL or the essentially saturated resorcinol polymer before adding to the rubber stock. In the example a resorcinol polymer containing free resorcinol is prepared by condensing allyl alcohol and resorcinol using HCl or H 2 SO 4  as catalyst. The polymer is added to a rubber stock comprising smoked sheet rubber, styrene-butadiene copolymer rubber, furnace carbon black, silica, zinc oxide, stearic acid, hexamethylenetetramine, sulphur and N-tertbutyl - 2 - benzothiazolesulphenamide. Untreated nylon and rayon tyre cords are embedded in the rubber stock which is then cured. Rubbers which may be used include natural rubber and synthetic rubbers, e.g. styrenebutadiene copolymer, isobutylene isoprene copolymer, ethylene-propylene-diene terpolymers, butadiene-acrylonitrile copolymers, polychloroprene and polyisoprene.

Patent GB-793255-A (GB)
Title: Detergent compositions
IPC: C11D3/06
Filed: 1955-02-11
Abstract: A detergent composition consists of an alkali metal polyphosphate or polymetaphosphate in a voluminous form, i.e. with a bulk weight below 70 g. per 100 ccs., together with other cleaning agent constituents, also present in voluminous form and previously produced in a separate process.  The phosphate is converted into a voluminous form either (i) indirectly, by spray-drying a solution of an alkali metal orthophosphate to a voluminous calcinate, and then raising this calcinate to 250-400 DEG  C. to produce a voluminous polyphosphate, or (ii) directly, by redissolving a solidified polyphosphate or polymetaphosphate melt in water and spray-drying the solution.  If desired, alkali metal sulphates or silicates and magnesium sulphates may be incorporated in the phosphate melts or solutions to be treated.  The other ingredients of the composition, such as soap, alkyl sulphate, alkyl aryl sulphonate, ethylene oxide condensate, cellulose derivatives such as sodium cellulose glycolate, diglycolic acid, optical clarifiers, protective colloids or fillers, may be sprayed separately to voluminous form before being mixed with the phosphate.  The uniformly low bulk density is said to overcome the separation of the ingredients during transport and handling, and the separate spray-drying of the phosphate melt is said to result in diminished hydrolysis of the polyphosphate.

Patent GB-1033654-A (GB)
Title: Process and apparatus for the hot enamelling of glass
IPC: C03C17/06
Filed: 1963-02-01
Abstract: In the hot enamelling of glass, enamel powder is distributed from a hopper in a layer on an endless moving belt from which it is discharged due to collapse of the powder at the front of the layer at a turn of the belt on to glass having sufficient temperature to cause the <PICT:1033654/C1/1> <PICT:1033654/C1/2> powder to melt, the glass moving transversely of the falling powder at a speed greater than that of the belt.  As shown in Figs. 1 and 3, enamel powder is in a hopper 10 with lower opening adjustable by nuts 14, 14a on eyenut 13 by which one side 11 is secured to the framework 12, the powder being deposited on an endless rubber belt 9 passing around shafts 5, 8 adjustable to maintain tension in the belt. Half bricks B of glass are passed on a conveyer belt 16 from the moulding unit to a further unit where they are joined together to form the final bricks, each brick B passing under the belt 9 to receive a coating of enamel powder on the inside which is melted by the heat of the moulded glass.  A mash 23 is shaped to cover the edges of the brick B and has an outer channel to collect excess powder and a sieve 24 through which the powder falls on to the brick B.  The mash 23 has a projection 29 by which it is carried along by a brick.  The mash 23 is mounted by arms 22 on a sleeve 19 sliding on a rail 17 alongside the conveyer 16, the sleeve being maintained central by rollers 20, 21 but also being pivotable by a counterweight 26 on a bar 25 to raise the mash 23 at the end of the enamelling cycle to allow the enamelled brick to pass onwards while the mash 23 is returned for the next brick by the engagement of the pivoted bar 25 with the continuously rotated roller 32, the mash 23 being maintained horizontal by a roller 27 on an electromagnet 28 for the forward movement and returned to the horizontal by a roller 34 before passing under belt 9.  Contractors 30 and 31, closed by the sleeve 19, energize and deenergize the electromagnet 28 respectively.  The belt 9 is driven only when the brick B and mash 23 are passing below by means of a screen 35 on bar 25, cutting-off a beam of light energizing a photo-electric cell 36 to actuate a clutch 37 between shaft 5 and a motor unit 2, an electromagnetic brake 38 being operated and the clutch 37 disengaged when the beam of light is restored.  A relay system prevents actuation of the clutch 37 on the return of the mash 23. The enamelling apparatus can be applied to drawn glass (Figs. 7 and 8, not shown), when no mash is used but the process is continuous and the enamelled glass may then be corrugated by rollers engaging the glass over a fluted table.
