Title: A method and an apparatus for the manufacture of short length filaments from thermoplastic thread-forming material
IPC: B01J2/00
Filed: 1960-07-29
Abstract: <PICT:0909147/IV(a)/1> <PICT:0909147/IV(a)/2> Short length artificial filaments are produced by melt spinning a synthetic organic thermoplastic material such as a polyaminocaproic acid from a spinning head 3 (Fig. 1) into a quenching bath of water 5 in the form of a bundle of filaments 4 which are drawn over deflecting members 7 and 8 to a filament cutting device 10.  The deflecting member 7 consists of a tube 11 (Fig. 2) closed at both ends and having a longitudinal slit-like opening 12 provided at each end with a projecting pin 13. Opposite the opening 12 the tube 11 communicates with a cold water supply line 14 provided with a control valve 15. The thickness and the number of filaments 4 on the one hand and the distance between the pins 13 on the other are so related that the filaments contact one another as they are drawn over the slot 12 of the deflecting member 7.  By adjusting by means of the valve 15 the force with which cold water is discharged from the slot 12 against the filaments 4 the latter can be caused to adhere to each other slightly.  Short ength filaments thus produced have a very uniform size and shape, rendering them suitable for the melt spinning of continuous filaments and for injection moulding.

Title: Improvements in or relating to centrifugal apparatus such as pumps, fans and compressors for the circulation of fluids
IPC: F04D29/22
Filed: 1953-09-29
Abstract: 737,833. Centrifugal fans &c. SOC. ANON DES ETABLISSEMENTS NEU. Sept. 29, 1953 [Nov. 15, 1952], No. 26757/53. Class 110 (1). In a centrifugal pump, fan or compressor comprising an impeller having a peripheral rotary diffuser, auxiliary vanes are secured to the outer faces of the rotary diffuser, the vanes being adapted to carry along the fluid situated between the impeller and the casing so as to increase the pressure, particularly at low outputs. An impeller comprises side discs 4, 5 which are extended by discs 17, 18 which form a rotary diffuser beyond the outer ends of the impeller blades 19. Auxiliary vanes 20, 21 cause rotation of the fluid in the lateral spaces 2, 3 between the impeller and the casing so that the whirl velocity of the fluid is substantially the same as that of the fluid discharged by the impeller, thus reducing the friction tending to slow down the discharged fluid. This reduces the tendency towards instability at low outputs. The auxiliary vanes may be located near the periphery 22 of the rotary diffuser.

Title: Improvements in or relating to door closers
IPC: E05F3/10
Filed: 1947-10-06
Abstract: 628,941. Door-operating appliances; stays for hinged articles. ROLLINGS, R. E., and BELL, F. A. Oct. 6, 1947, No. 26834. [Class 65 (i)] A spring door-closer combined with air-dashpot check means is provided with an additional opening for the escape of air from the check cylinder and with a valve adapted to be unseated by the check piston as the door approaches the closed position to control the escape of air. As shown, a cylinder 17 contains a closing spring 18 and check piston 21, whilst the cylinder head 23 is provided with a check opening 24 controlled by a non-return ball valve 25 and a needle valve 26. An additional opening 28 in the cylinder head, communicating with an annular groove 27, is controlled by a valve 41 which comprises a centrally apertured stem 42 arranged to slide within a split sleeve 45 fixed in the cylinder, and a flexible annular part 43. The valve 41 is urged by a spring 46 towards the cylinder head and engages the latter on both the inner and outer sides of the annular groove to prevent communication between the cylinder and the opening 28, whilst leaving the cylinder in communication with the opening 24. Bell-crank levers 51 pivoted to the sleeve 45 are arranged with radially extending arms connected to the valve stem 42 and with axially extending arms adapted to be moved apart by a boss 52 on the piston when the latter approaches the head 23. The opening 28 is provided with a valve disc 56 pressed on a seating by a spring 58 and formed with a central orifice controlled by a needle valve 61. During opening of the door, when the piston moves away from the head 23, valves 41 and 56 lift off their seats, allowing free ingress of air through the opening 28. Movement of the piston to effect closure of the door forces air through the restricted opening 24 until the boss 52 moves the bell-crank lever arms apart to unseat the valve 41, when the opening 28 is connected to the cylinder and air can escape through the orifice in the valve 56 to provide a greater closing force for overcoming the resistance of the door latch. The head 23 is pivoted to the door whilst the piston rod is pivoted to an elbow linkage, the ends of which are connected respectively to the door and door frame. The head at the other end of the cylinder is provided with means adapted to clamp the piston rod relative to the cylinder for holding the door in any desired position. The Provisional Specification states that checking may be effected by liquid instead of air, the inlet and outlet passages in the cylinder head being, in that case, connected to a liquid reservoir.

Title: Improvements in making trichloromethyl compounds
IPC: C07C17/26
Filed: 1948-10-18
Abstract: Trichlormethyl compounds are obtained by reacting trichlormethane sulphonyl chloride with an olefinic compound devoid of aromatic groups on the ethylenically unsaturated carbon atoms, with elimination of sulphur dioxide and addition of the fragments CCl3- and Cl to the olefinic compound.  Minor amounts of higher molecular weight compounds are sometimes produced.  The use of a promoter such as a source of free radicals is usually unnecessary, but may be used. Suitable olefins include olefinic hydrocarbons, halogenated olefinic hydrocarbons, olefinic alcohols, ethers and thioethers of olefinic alcohols, esters of olefinic alcohols and mono- and poly-basic saturated and ethylenically unsaturated acids, olefinic acids and derivatives thereof such as nitriles, esters, chlorides, anhydrides and amides, olefinic amines, olefinic amides, olefinic imides, olefinic aldehydes and ketones, trimethyl allyl silane and methyl allyl sulphone.  Many typical examples of compounds of the above general types are specified.  A preferred class are those having the general formula CH2= CRR1 where R and R1 may be hydrogen or methyl and R1 may additionally be alkyl, acyl, alkoxy, aryloxy, methylol, acylmethyl, acyloxymethyl, alkoxymethyl or aryloxymethyl.  The reaction is generally carried out by heating one mol. of the ethylenic compound with from 0.5 to 20 mols. of trichlormethane sulphonyl chloride at 25-125 DEG  C., preferably 50-100 DEG  C., for 5 to 80 hours.  A liquid hydrocarbon, alcohol, ether or ester may be present as a solvent or diluent. Pressures of 100-500 pounds per square inch may be used when reacting a gaseous olefine.  Examples are given of the preparation of 1,1,1,3-tetrachlorononane, 1,1,1,3-tetrachloropropane, 1,1,1,5-tetrachloro-3-methylpentene-2, 2,4,4,4-tetrachlorobutyl acetate and 2,4,4,4-tetrachlorobutanol.
