Title: Improvements in plasticised polyvinyl acetal resins
IPC: C08K5/00
Filed: 1937-11-17
Abstract: 509,696. Polyvinyl acetal resin compositions. JACKSON, L. MELLERSH- (Fiberloid Corporation). Nov. 17, 1937, No. 31637. [Class 2 (iii)] Interleaf material for safety glass comprises polyvinyl acetal resin and a mixture of plasticizers in such proportion that the mixture is compatible with the resin and substantially equal hot and cold break tests are obtained, one or both of the plasticizers being incompatible if used alone in the proportion of the total plasticizer mixture. Further, one of the plastizicers may be incompatible if used alone in the proportion used in the mixture ; and the mixture may be used in a proportion which is nearly incompatible. Thus, a polyvinyl butyraldehyde acetal resin containing less than 25 per cent. hydroxyl may be mixed with amyl or butyl laurate and a phthalate of a monohydric alcohol containing less than 8 carbon atoms. Detailed examples show the use of mixtures of dibutyl phthate or diethyleneglycol dibutyrate and phenyl-ethyl alcohol, diethyleneglycol dipropionate and butylcarbitol butyrate, dilauryl phthalate and diethyleneglycol or dibutyl diglycollate, amyl or butyl laurate and dibutyl phthalate or phenyl-ethyl alcohol.

Title: Improvements in the production of fibres or threads from glass, slag and the like meltable materials
IPC: C03B37/05
Filed: 1931-11-16
Abstract: 373,932. Slagwool. NAAMLOOZE VENNOOTSCHAP TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN, 57, Zeekant, The Hague. Nov. 16, 1931, No. 31696. Convention date, Nov. 29, 1930. [Class 22.] A method of making fibres or threads from molten glass, slag, or like fusible material, consists in flowing the molten mass in a thin stream on to a rapidly rotating body from which it is thrown off in the form of fine fibres by centrifugal force. The glass or slag is melted in a furnace 1, and the molten material flows out through an aperture 4. The space below the aperture is enclosed by annular walls 7, 8, a narrow gap 9 being left between the two walls. A disc 10 secured to the upper end of a vertical shaft 13 is arranged below the aperture 4, the upper surface of the disc being arranged at the same level as the top of the wall 8. A pulley 14 and a belt 15, or other suitable drive, is provided for rotating the shaft at a high speed. When the molten material flows from the aperture 4 on to the disc 10, it is thrown outwards and forms a mass of thin threads which settle down between the disc and the wall 8 and form an envelope surrounding the disc. This envelope is cut from time to time by mechanically-operated shears 18. Particles of material which are too heavy are thrown through the gap 9 and fall into a gutter 16. In a modification, the axis of the disc 10 may be horizontal or inclined to the vertical, and in this case, the molten material is flowed on to the circumference of the disc.

Patent GB-748852-A (GB)
Title: Improvements in or relating to power-driven typewriters
IPC: B41J7/44
Filed: 1953-11-16
Abstract: 748,852. Typewriters. RHEINMETALL - AKT.. GES. Nov. 16, 1953 [Nov. 29, 1952], No. 31777/53. Class 100 (4). In a typewriter having a power-driven toothed wheel which engages a pawl to operate a type bar, a locking device which is operative until shortly after the type bar struck has started its movement towards the platen is provided to prevent the simultaneous striking of several keys. Depression of a key 18 acts through a pin and slot connection 31, 29 to depress a locking slide 27 against a spring 32 so that the usual rollers 25 are separated and prevent the movement of the other keys. This downward movement of the slide 27 causes an inclined surface 38 to engage a projection 39 of a toothed pawl 3 first moving the latter to the right so that a pin 19 is disengaged from a notch 20 in a pawl carrier 6 thus allowing a spring 17 to pull the pawl 3 to the left until its pin 4 again engages the left. hand end of the slot 5 in the carrier 6 and at the same time the spring 17 draws the pawl into engagement with the toothed shaft 1. The pawl 3 is now driven to the right until the pin 4 engages the right-hand end of the slot 5 and then moves the carrier 6, which through a pin and slot connection 7, 8, actuates the type bar mechanism 10, 11, 12. As the carrier 6 moves to the right and starts the type bar movement an inclined surface 24 contacts a release pin 34 to move the locking slide 27 to the right so that the pin 31 moves over the vertical part of the slot 29 and allows the spring 32 to withdraw the slide from the rollers 25 as the pin 31 reaches the bottom of the slot and the other keys are thus unlocked. The shaft 1 continues to drive through the pawl 3 until a disengaging arm 41 contacts a rack 42 which pivots the pawl about the pin 4 so that it is withdrawn from the shaft, the type bar mechanism continuing to strike under its own momentum. The point at which the pawl is withdrawn, and thus the striking force, can be adjusted for all the types by a knob 43 which moves the rack 42 or individual types can be adjusted by bending individual teeth 44 of the rack. As the arm 41 moves away from the rack 42 on the return of the type bar the spring 17 will restore the pin 19 into the notch 20 thus holding the pawl in the inoperative position and positively preventing repeated actuation until the key is restored and again struck. Movement of the pin 4 in the slot 5 when the pawl 3 and shaft 1 engage before the movement of the type bars is started ensures that the acceleration required takes place in two stages and wear is reduced.

Abstract: 982,507. Bearings. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 12, 1963 [Aug. 22, 1962], No. 31798/63. Heading F2A. [Also in Division H2] A rotatable member 1, having concentric annular ribs 7 and a conical-shaped face 5 thereon, is supported and centred by magnetic and fluid pressure means on a stationary member, having complementary concentric annular ribs 8 and a conical-shaped face thereon. The magnetic field is produced by a winding 9 and lines of force f of the induction circuit are completed via the member 2. Pressurized fluid is supplied to the clearance between the conical faces through a passage 6. The stationary member has an adjustable portion 3 which has the annular ribs 8 thereon and can be made to " float " by supplying pressurized fluid through a passage 11 in the stationary member. Thus, by releasing clamping bolts 4, the portion 3 can be aligned by screws 4a, so that the ribs 7 of the rotary member are exactly opposite the ribs 8 of the stationary member. The pressurized fluid is cut off and clamping is effected by the bolts 4. In an embodiment which incorporates the above, a squirrel-cage motor has an inner stator which may be cooled by a tube, closed at one end and having radial holes therein, through which cooling air is blown on to the windings. Alternatively, cooling may be effected by fins attached to the inner portion of the rotor.

Heading B2H [Also in Divisions B5 and C3] Wood chips for producing boards are fed to a strand 14, prior to pressing, through three spreaders, and a classifier 4 splits the chips into coarse fractions for feeding to the middle spreader and forming the middle part of a board, and into finer fractions for feeding to the two outermost spreaders and forming the two outer layers of the board. Wood chips are automatically fed from a discharge device 1a of a bunker to a feeder 2 and thence to a weighing device 3 which controls device 1a and feeds a constant amount of material to the classifier 4. The classifier comprises counterrotating pin rolls (4a) (Fig. 2, not shown) for loosening the chips, a separating roll (4b) therefor and shaped distributors (4e) which feed the separated fractions to screening devices (4c) - (4f). The coarse material passes from the screen (4f) to a weighing device 5, which also automatically controls the distributor (4e) via a line 5a. Air is removed at 6a, glue is added at 6 and the coarse chips are spread at 7 on the strand. 14. Coarser elements of the fine fractions from the classifier 4 are further communicated at 15, all the fines then passing through an air extractor 8a to a gluer 8, and thence by spreaders 12, 13 to the strand 14. Numerals 16, 17 indicate pneumatic flow lines for the materials.
