Title: Improvements in apparatus for feeding fibre stock
Inventor: MARVIN ARTHUR
IPC: D01G23/00
Filed: 1952-08-13
Abstract: 719.347. Fibre feeding-apparatus. T.M.M. (RESEARCH). Ltd. Aug. 7, 1953 [Aug. 13, 1952], No. 20357/52. Class 120(1) In fibre feeding apparatus of the type wherein surplus material is combed off a spiked feeding lattice by an advancing and receding comb, the comb receives simultaneously independent oscillatory motions about two different axes such that the angle of attack of the comb teeth, i.e. the angle between the comb teeth and the direction of motion of the lattice, is varied between a large angle on the working stroke and a smaller angle on the return stroke. As shown, the comb 13, which cooperates with the lattice 10 of a hopper feeder, is carried by hinge members 18 pivoted at 19 to the ends of arms 14 keyed to a rocking shaft 15. A crank pin 27 carried by a rotating wheel 28 is journalled in a cross-head 25 slidable on an arm 26 fixed to shaft 15. Cross-head 25 is also connected by a link 24 to an arm 23 of a double-armed lever loosely mounted on shaft 15, the other arm 22 of the lever being connected by a link 20 to a pivot 21 on the comb 13. Rotation of wheel 28 thus oscillates arms 14 with a quick return motion and also causes an in-phase oscillation of the comb about pivot 19. The resultant motion of the comb is indicated in dotted lines, the comb presents a large angle of attack during its working stroke from position 13A to position 13B, and a small angle as shown at 13C during its return stroke. The path traced by the tips of the comb teeth is substantially elliptical on the working stroke and substantially straight on the return stroke. The position of pin 27 on wheel 28 can be varied to adjust the amplitude of oscillation of the comb; also the bearing blocks of shaft 15 can be adjusted towards or away from the lattice 10 by rack and pinion mechanism for varying the thickness of the layer of material on the lattice whilst the machine is running.

Title: Process and device for finishing spoons, forks and like table ware
IPC: B24B19/00
Filed: 1929-07-04
Abstract: 328,165. Kocherscheidt, W. July 4, 1929. Spoons and forks, table and like.-The edges of a spoon &c. are finished by holding the spoon 1 by hooks 3 on a carrier 2, capable of either reciprocating or traversing motion past cutters 5 and leather covered buffing-wheels 6. The cutters and grinding-wheels are attached to staggered guide rods 12, 13 and 18, 19 respectively, adapted to be resiliently pressed towards the work by springs 16, 21. The motion of the rods is determined by wheels 14 and 22 adapted to bear on the lower portion of the carrier 2 which is shaped as a template for the work. The cutters are rotated by bevel gearing 8 from a pulley 10, the grinding-wheels being driven directly from pulleys 11. In an alternative construction, the spoons are mounted on an endless band and are automatically released from beneath the retaining hooks when the band passes over a pulley. In this case the wheels may be driven by means of flexible or universally jointed connections from a self-contained electric motor.

An additional earthed external electrode 10 may be provided which re-starts the discharge when moved towards the tube ; or the tube may be surrounded by an earthed conducting cage 11 acting as a shield against the influence of movable earthed or non-earthed conductors.
Patent GB-582721-A (GB)
Title: Improvements in or relating to vinylidene chloride compositions
IPC: C08K5/12
Filed: 1943-12-08
Abstract: Vinylidene polymers and copolymers are stabilised by the addition of an organic ester of endo-methylene-tetrahydrophthalic acid of the general formula <FORM:0582721/IV/1> where R may be an alkyl, alkenyl, alkynyl, aralkyl, or cyclo-aliphatic radical or their halogen substitution products. The stabilisers may be present in an amount of 1 to 3 per cent by weight of the resin although 5 to 20 per cent is preferred. Preferred esters are those derived from the lower alcohols such as ethyl or butyl alcohols or of the higher aliphatic alcohols such as hexyl and octyl alcohols, although those prepared from unsaturated alcohols such as allyl, methallyl, chlorallyl and cinnamyl alcohols or from alcohols containing an acetylenic linkage such as propargyl alcohol may also be used.  The stabilisers may be added to the resin by any known means such as dissolving in a solvent, adding the resin and evaporating off the solvent, or by milling on hot rollers.  The compounds may also contain plasticizers and may be used to produce sheets, moulded masses and articles.  In examples: (1) polyvinylidene chloride is stabilized with the dialkyl ester of the acid, tricresyl phosphate in ether added, the ether evaporated off, and the powder moulded to disc shape; (2) vinylidene chloride/diethyl maleate copolymer is stabilized with the dibutyl ester; (3) vinylidene chloride/ethyl acylate copolymer is mixed with the dipropargyl ester and dihexyl sebacate in petrol ether and the ether removed and (4) vinylidene chloride/vinyl chloride copolymer is mixed with the dibutyl ester and tricresyl phosphate in ether and the ether evaporated off.

Title: Manufacture of mono-n-alkanol derivatives of aromatic di-amines and poly-amines
IPC: A01B19/02
Filed: 1932-07-21
Abstract: Mono-N-alkanol derivatives of primary di-or polyamines of the benzene series are made by condensing equimolecular proportions of the primary di- or polyamine of the benzene series and a halogenalkanol together in presence of a suitable solvent and of an acid-binding agent.  The products obtained are unitary compounds.  In examples, p-phenylenediamine, 2 : 4-diaminochlorobenzene and 1 : 2 : 4-triaminobenzene are condensed with an equimolecular proportion of monochlorhydrin in methanol and in presence of caustic potash to give N-mono-(dioxypropyl)-p-phenylenediamine, N-mono-(dioxypropyl)-chloro-m-phenylenediamine and N-mono-(dioxypropyl)-1 : 2 : 4-triaminobenzene respectively, and similarly 2 : 4-diaminotoluene is condensed with an equimolecular proportion of ethylenechlorhydrin to give N-mono-oxyethyl-m-toluenediamine.  The Specification as open to inspection under Sect. 91 relates to the production of mono-N-alkanol derivatives of aromatic di- or polyamines generally by the above process, but this subject-matter does not appear in the Specification as accepted.

As shown the capacitors to the right of those stages which are conductive have their lower plates near reference potential, so that after the negative supply U has been reduced to zero by a first pulse to shut down all stages, when a positive pulse is applied to L 1  only the stages to the right of these capacitors are switched on. Fig. 2 (not shown) illustrates a modification using further conventional diodes to shorten the recovery time essential between pairs of shifting pulses.

Abstract: 206,239. Iron, G. W. Aug. 2. 1922. No Patent granted (Sealing fee not paid). Cataracts.-Relates to devices for cushioning the movements of hinged articles, which also serve to hold them in any position and as shown applied to a door comprises two curved tubes a, b adapted to telescope one within the other, the outer one being fixed to the door f and the inner one to the wall, the joint at d being liquid-tight; these tubes are filled with liquid and communicate through a chamber e and pipes g, h with a tank i fixed to the door. The pipe g leads to the top of the tank and has a cock l and non-return valves j allowing of upward flow only, while the pipe h leads from the bottom of the tank and has a non-return valve allowing of downward flow only. With the cock l closed the door cannot be opened'; the stem of this cock may extend through the doors so that it may be operated from the outside by a key. On turning the cock and opening the door, liquid passes bv way of pipe g to the tank i; on releasing the door the non-return valves, which are spring-pressed, serve to hold it, and closing the cock l prevents it being opened further. Closing the door causes a suction which lifts the non-return valve in the pipe h and draws liquid from the tank. Air may be used as the cushioning medium, a simple valve being then fitted at the end of the tube b. Several hinged articles may be controlled simultaneously and the control may be from a distance.
