Title: Refractory materials
Inventor: GILPIN WILLIAM CECIL
IPC: C04B35/03
Filed: 1964-12-21
Abstract: 1,137,831. Tar bonded dolomite refractories. STEETLEY REFRACTORY BRICK CO. Ltd. 20 Dec., 1965 [21 Dec., 1964; 21 July, 1965], Nos. 51883/64 and 31071/65. Heading C1J. A method of making a refractory composition, suitable for making refractory shapes or linings for steel furnaces, comprises mixing a tar with dead-burned dolomite, (doloma) optionally with dead-burned magnesite, and maintaining the mixture at a temperature above 175‹ C. and below 500‹ C. for at least one minute. The hydration resistance of the dead-burned material is thus improved. Less than the total amount of tar needed to make a tar-bonded refractory may be added initially, the balance being added later. Coke oven tar is preferred, but pitch may be used. The tar may be added to hot doloma, e.g. at 300‹ C., leaving the burning kiln, or may be added to crushed doloma, the mixture then being heated to the desired temperature. Comparative examples are described.

Title: Cartridge for flexible strip material

Abstract: 1,096,300. Record tape cartridges. EASTMAN KODAK CO. Dec. 23, 1964 [Dec. 30, 1963], No. 52183/64. Heading G5R. [Also in Division G2] In a magnetic tape cartridge divided into a supply chamber 28 and a take up chamber by a wall 32 (Fig. 4), the wall has a recess 34 opening into the supply chamber and a boss 36 on which are rotatably mounted a disc 38 and a coiled coreless roll of tape 44, the disc having an outer lip 42, 43 to prevent the film from clockspringing to contact the walls of the supply chamber and overlying the recess 34 so that when tape 44 is withdrawn from the coil, the edge of the tape presses down the lip 42, 43. An inner lip 47 may be provided to prevent the tape tightening round the boss 36. Tape 46 is fed from the coil 44 over guides 48, 50 (Fig. 1) across a pressure pad 52, and into a take up chamber 30 where it is attached to a core 56 rotatably mounted on the wall 32, coaxially with the feed coil. A cover 14 may be put on the cartridge body, the core 56 being aligned with an aperture 27 so that a drive member of the apparatus in which the cartridge is inserted can be coupled with a key 58. In a cinematograph film embodiment, an aperture 24 in the cover is positioned so that an intermittent feed claw (not shown) can extend through the aperture to engage perforations in the film 46 and intermittently advance the film over the pressure pad 52. A modified form of the disc 38 is described (Fig. 5, not shown).

Abstract: 1,057,209. Axial flow fans; ducted fan blades; gas turbine ducted fan engines. GENERAL MOTORS CORPORATION. Dec. 9, 1965 [Dec. 17, 1964], No.52281/65. Headings F1C, F1J and F1T. In a gas turbine ducted fan engine in which the fan rotor blades 41, Fig. 1 (not shown) extend across the compressor inlet 29 and the inlet of the by-pass duct 27, the air inlet 11 preceding the blades 41 is undivided but the fan rotor has an annular flow divider 48 immediately upstream of a stationary fairing 51 separating the by-pass duct from the compressor inlet. The radially outer part 47 of each blade 41 may be of different configuration from the radially inner part 46. Instead of being solid, each blade 41 may comprise a thick plate 52, Fig. 4, and a light sheet metal plate 54 brazed or otherwise fixed to the plate 52 adjacent its leading and trailing edges and at a rib 53. The annular flow divider 48 is formed by flanges 56 extending from the plates 52, a narrow gap 57 being left between adjoining flanges. A disc 63 contained in a circular recess formed partly in each flange 56 and partly in the adjoining flange 56 is pressed by centrifugal force against the radially-outer surface of the recess, so that any relative motion between the flanges due to blade vibration is damped by frictional engagement between the disc and the surface.

Title: Control system for high-speed printing machines
IPC: G06K15/08
Filed: 1971-11-11
Abstract: 1345805 Printers HONEYWELL INFORMATION SYSTEMS ITALIA SpA 11 Nov 1971 [11 Nov 1970] 52447/71 Heading G4H In an on-the-fly printer, a count representing actual type carrier position is compared with a required character code from a store, the comparison operation being modified according to the frequency of occurrence of the relevant character on the carrier. In a chain printer, with the type chain running along the print line, the codes representing the required characters are modified (using an arithmetic unit) according to their positions in the print line, and stored. At each time at which some characters can be printed (the hammer or &c. spacing differs from the type spacing on the chain), all the stored codes are read out and compared in turn with the count, equality causing a print pulse which is gated to the appropriate hammer or &c. under control of further counters. The stored codes each contain, or are accompanied by, one or more bits specifying the frequency of occurrence of the respective character on the type chain, which disable part of the comparator to cause part of the comparands to be ignored, or modify part of one or both comparands by logic, so that the first occurrence on the type chain of the required character will be used. These bits may come from the first-mentioned counter instead. A further alternative is to also vary the effect on the comparands in accordance with signals from a sensor on the type-carrier, or manual input, specifying the frequency pattern which can be changed. The stored code of a printed character is deleted to prevent repeated printing. The print pulses are counted, together with decoded "space" commands, to cause advance to the next line when the line has been printed. The invention is also applied to drum and paper tape printers, the character codes not requiring modification according to position in the print line in these cases.

The drain connection incorporates a needle valve 29 by the adjustment of which the fluid flowing out of chamber 12 and into the drain can be varied. The rate of such outflow determines in turn, the minimum amount of fluid constantly entering output connection 26 and constituting a bias pressure within the output. Fig. 3 indicates two such bias pressure levels Po, Pa of which the former corresponds to the fully open position of the needle valve 29. Upon the rotor being operated, the bias pressure Po or Pa within output 26 has superimposed thereon periodic pulses as shown in Fig. 3, such pulses being created by surface D intercepting the input fluid flow and deflecting such flow into output 26. The amplitude and/or duration of the superimposed signals may be varied by altering either the supply pressure or the diameter of the output 26.
