Patent GB-336727-A (GB)
Title: Improvements relating to the casting of molten metals or alloys
IPC: B22D11/06
Filed: 1929-08-27
Abstract: 336,727. Harris, H. Aug. 27, 1929. Casting-machines ; moulds. - In continuous casting by feeding molten metal to a convergent space between two moving surfaces, the temperature and head of metal are kept at a value which will cause the metal to be solidified and then compressed and moulded in the gap between the surfaces. The space 3 between the rollers 1, 2 is formed into a hopper by end plate 4 which may serve as a weir to keep a constant level, excess metal passing through an outlet 6. In a modification, the metal is supplied to the hopper at a constant rate by a nozzle 12, Fig. 3, connected to a tank or tanks 14, kept at a fixed level by floatoperated valves 16 or an adjustable overflow 26, Fig. 4. The nozzle may take the form of a perforated pipe 12 or a chamber 19 with a slot 18 of adjustable width. The chamber 19 may be heated by gas burners 21 and the hot gases may be conducted over the conduits 13, 24 and tanks 23, 15 by casings 40, Fig. 4. The plates 4 may have tapering projections 28, Fig. 7, to engage the space 3. The rollers 1, 2 may be cooled internally by water supplied by pipes 8, Fig. 1, and discharged by flanges 10 and funnels 11. The faces of the rollers may be patterned or grooved and between them may be fed a strip of solid metal which becomes united to the metal cast. The apparatus may operate wholly or partly in neutral or reducing gas. The Provisional Specification describes the cooling of the surfaces by immersion in water or circulation of water through them and also a machine in which the gap is partly occupied by a partition or core.

Patent GB-389521-A (GB)
Title: Improvements in the manufacture and treatment of artificial silk, films and the like
IPC: D01F2/28
Filed: 1931-09-18
Abstract: Artificial filaments, films, and the like are delustred by forming in the materials a finely divided substantially white organic compound which does not melt below about 200 DEG  C.  The organic compound may be formed by the interaction of two reagents, one of which is incorporated in the spinning solution and the other applied to the materials subsequent to their formation.  Alternatively the filaments &c. may be caused to absorb one of the said reagents and then treated with the second reagent to precipitate the organic compound. Particularly suitable organic compounds are the acidyl derivatives of benzidine and like diamino bases.  The benzidine or other base may be applied to the filaments &c. in solution, e.g. in hydrochloric acid, or as a dispersion, suitable dispersing agents being Turkey red oil, the naphthenic acids, sulphonated naphthalene compounds, sulphite cellulose waste liquor, or the dispersing agents of Specifications 219,349, 224,925, 242,393, 273,819, or 273,820, [all in Class 15 (ii), Dyeing, Processes &c. for].  The dispersing agents may be used with auxiliary solvents, such as those of Specifications 242,711 or 269,960, [both in Class 15 (ii), Dyeing, Processes &c. for].  The second reagent may be applied at any suitable stage, for example, when the first reagent is incorporated in the spinning solution, the second reagent may be applied continuously with the production of the filaments &c., for example, by adding to a suitable coagulating bath, or may be applied at a later stage.  Local application of either the first or second reagent may be employed to produce local lustre effects. It is desirable to choose reagents which require ordinary or only moderately high temperatures for reaction, and to avoid the use of media which unduly affect the material of which the filaments &c. are composed; e.g. where pyridine is used to effect the reaction between benzidine and benzoyl chloride, it should be diluted with benzene, toluene, xylene, or like hydrocarbons to avoid solvent action upon the cellulose acetate or like filaments.  The process may be applied to the production of delustred filaments &c. from cellulose esters, ethers, ether-esters, viscose, or cuprammonium. In examples, (1) cellulose acetate solution containing benzidine is extruded into filaments which are treated continuously with their production in a benzene solution of acetic anhydride; (2) cellulose acetate fabric is immersed first in an alcoholic solution of benzidine and then in toluene containing benzoyl chloride and pyridine.  Specifications 316,169, 316,638, [both in Class 2 (ii), Cellulose &c.], and 363,986 also are referred to.

Abstract: 1317772 Optical viewing system HUGHES AIRCRAFT CO 1 June 1970 [4 June 1969] 26344/70 Heading G2J [Also in Division H4] An optical viewing system 12 comprises a viewing device mounted in a frame 28 having an optical axis 34 fixed with respect to the frame, and a mirror 46 inclined, for example at 45 degrees to the axis 34, so defining an image path 56. The viewing device may be an image intensifier 36 having zoom characteristics, and there may be a further intensifier 38. The mirror is mounted in a housing 48 which is rotatable about axis 34 on bearings 50 by means of ring gear 52, and which carries a further housing 58, rotatable about axis 56 on bearings 60 by means of ring gear 62, in which is mounted a second mirror 64 inclined, for example at 45 degrees to the path 56, so defining a direction of view 66 through window 68. The system may include a lens assembly 54 between the mirrors and the picture formed by the image intensifiers is received by the end of fibre optic bundle 22. A control system, Fig. 4 (not shown) controls motors driving ring gears 52 and 62 to vary the elevation and azimuth respectively of viewing direction 66, and there are feedback loops to maintain the orientation of the system in space during movement of the frame 28, employing signals from gyros 70 and 72 mounted in the housing 58. The signals from these also control a motor driving ring gear 44 which rotates the image intensifiers and the end of the fibre bundle 22 to produce an upright image. In a modification (14), Fig. 3 (not shown) the fibre bundle 22 is replaced by a ridicon (98). Systems 12 and (14) may be mounted on an aircraft, for example a helicopter (10), Fig. 1 (not shown), the signal from fibre optic bundle 22 being passed to eyepiece (24) and the signal from ridicon (98) to at least display tube (26). The orientation of the system may be connected with that of search lights (16) and (18) and guns (20).

[Class 100 (iv).] Paper-carriages; key locks ; carriage-releasing arraregements.-A centring stop for the carriage is directly connected by a link to the shift-locking key, movement of the centring stop into operative position releasing the locking key, if in depressed position, and thereby permitting the carriage to return to lower-case position. The centring stop may be arranged also to retain the letter-spacing mechanism in disengaged position. The machine shown in Figs. 2 and 5 includes, as described in Specification 247,512, [Class 100 (iv), Typewriters &c.], a carriage C mounted on a rocking shiftframe B which is connected by a link 14 to a shift-key lever 9 provided with a locking key 15. The centring stop 30, Fig. 2, consists of a bell crank pivoted on the framework A and connected to a link 36 having a loop 39 engaging a pin 38 on the locking key. When the centring stop is moved rearwards, a lug 32 thereon can co-operate with the rail 6 to centre the carriage, and if the locking key has been depressed it is released by the link 36. Stops 34, 35 limit movement of the centring stop, and a returning spring may be provided. The centring stop 40, Fig. 5, is connected by a looped link 50 to the locking key, and has a finger 46 arranged to enter a hook 47 formed on one of the releasing levers 26 carrying the feed rack 24. When the. carriage has been centred, the centring stop is moved rearwards and the finger and hook cooperate to prevent movement of the carriage in either direction, and to hold the feed rack 24 in disengaged position, the locking key, if in depressed position, being released by the link 50.
