Abstract: 801,497. Silencing suction rolls in papermaking machines. NATIONAL RESEARCH COUNCIL. April 30, 1956 [May 9, 1955], No. 13169/56. Class 96. A silencer for a rotatable suction or couch roll 2 comprises a chamber 1 arranged next to the leaving edge 3 of a stationary suction-box 4, the chamber having a gap 7 that is narrower than any of the radial holes 5 and allows communication between them and the chamber 1 during rotation. The gap 7 may be cut in a strip 8 which is attached to the chamber 1 and whose width is at least twice the diameter of the holes 5, the gap connecting with the chamber by means of apertures 9b circumscribing an area 9 of the strip; alternatively, the gap may connect directly with the chamber without the intermediary of a strip. The chamber 1 is placed in limited communication with the atmosphere by at least one inlet 10 in one or more walls of the chamber, the inlet or inlets being positioned adjacent the ends of the chamber, leaving the central portion thereof imperforate. The inlet 10 can be filled with a tube 10A carrying a valve, e.g. butterfly valve 11, to compensate for changes in suction roll speed. The chamber and gap extend substantially the length of the roll, and the width of the gap lies preferably between 0.020 and 0.030 inches, but up to 0.220 inches is allowable.

Filed: 1958-04-25
Abstract: 899,852. Gain control. MANDREL INDUSTRIES Inc. June 25, 1958, No. 13279/58. Class 40(5). [Also in Group XL(b)] The gain of an amplifier is varied by controlling the screen grid potential of the input valve. In a photo-electric system for sorting lemons according to reflectivity, variations in stray light reaching the photo-multiplier 11 are corrected by intermittently exposing it to a dark background, measuring the output of the amplifier at potentiometer 44, and using the output to control a pentode 24 which controls the screen grid potential of the input pentode 12 to vary the amplifier gain to maintain its output for the reference background equal to a preset value. The preset value is adjustable by adjusting tapping 112. Specification 899,853 and U.S.A.

Abstract: Catalysts used in the polymerization of ethylene (Group IV (a)) are obtained by heating aluminium with a halide or oxyhalide of a Group IVA metal at a temperature up to 300 DEG  C. and in the absence of polymerizable compounds.  The aluminium is preferably pure and is desirably finely divided.  Specified IVA metal compounds are molybdenum pentachloride and tungsten oxychloride.  Sulphur compound-free diluents may be used in the preparation of the catalyst and in the polymerization, e.g. distilled benzene. Catalyst residues may be removed from the products with methanolic hydrochloric acid and/or cyclohexane.ALSO:Ethylene is polymerized using as catalyst the product obtained by heating aluminium with a halide or oxyhalide of a Group IVa metal at a temperature up to 300 DEG  C. and in the absence of polymerizable compounds.  The aluminium is preferably used in the pure state and is desirably finely divided, but the ethylene may be a technical grade and in an example is added intermittently in the polymerization.  Specified IVa metal compounds are molybdenum pentachloride and tungsten oxychloride.  Diluents which are free from sulphur compounds may be used in the preparation of the catalyst and in the polymerization and listed are benzene, hexane, heptane, decahydronaphthalene, cyclohexane and cyclohexene.  Alternatively the polymerization may be in bulk. Purification of products may be effected with methanolic hydrochloric acid and/or the use of cyclohexane.

Title: Improvements in or relating to cord reels for electrical appliances
IPC: B66D5/00
Filed: 1964-04-06
Abstract: 995,401. Winch brakes. ELECTROLUX Ltd. April 6, 1964 [April 23, 1963], No. 14067/64. Headings B8B and B8M. A braking device for a spring driven cord reel 10 for the electrical cord 15 of a vacuum cleaner comprises two brake blocks 29, 30 which co-operate with the inside of a drum 28 formed by the end wall 12 of the reel 10, so as to hold the reel 10 against the winding up action of a driving spring 26 after a length of cord has been pulled off the reel. The brake blocks 29, 30 are swingably supported on a bridge 34 rotatable about the shaft of the drum 28 and are actuated by a spring 31 into braking engagement with the drum and adapted by manual turning of the bridge 34 to be pressed against stationary stops 32 counteracting the spring 31 to eliminate the braking engagement. The cord reel 10 mounted in the end casing 36, Fig. 1 (not shown) of the cleaner incorporates a spring drum 25 on which the coil spring 26 is wound up from a spring magazine 27, Fig. 3 (not shown) as the cord 15 is pulled off the reel. As the cord pull is stopped the spring 26 tends to rewind the cord reel but the brake blocks 29, 30 which are pivoted about studs 33 on the bridge 34, engage the drum under the pivoted action of the spring 31 and prevent rewind. Each block 29, 30 is substantially rectangular in shape with a rounded drum engaging end with the radial distance about the pivot stud 33 increasing so that the braking friction force increases when the drum 28, due to the spring force 26 is caused to rotate counter-clockwise as seen in Fig. 4. The brake is released by rotating a lever 37, via a button 45, against the action of a return spring 41, to depress link 35 and rotate the bridge 34 in the direction of the spring load 26. This causes the blocks 29, 30 to engage fixed studs 32 causing a clockwise rotation of the blocks about their axes 33 whence the braking action is removed. The electrical supply is passed from the cord 15 into the internal wiring of the cleaner by means of contact springs 20 in the reel 10 and slip rings 21, 22 on a removable bore 24 within the cleaner.

Title: Improvements in or relating to closure members and pipe joints

Abstract: 659,524. Stoppers ; bungs. VAN LEER'S (CURACAO), N. V. May 26, 1949, No. 14122. Convention date, Feb. 17. [Classes 21 and 125(iii)] [Also in Group XXVIII] A joint between two members, one of which enters an opening in the other, e.g. a closure for a bottle, jar, can, barrel or the like, comprises an elastic ring 4 which, before the insertion of the closure 1, is square-sectioned and is accommodated in a recess between shoulders 5, 9 and, during the insertion, is rolled over on to the shoulder 5. In the first stage of the insertion, the resistance of the ring to rolling has to be overcome by downward pressure on the closure, but after reaching the snap position of the ring, the latter tries to complete the roll and the closure is drawn into the mouth of the bottle. The completion of the roll is prevented by the ring contacting with a flange 7 on the closure 1. A wiping ring 11 may be provided in the shoulder 9 to ,clean the neck of the bottle and thus avoid interference with the rolling of the ring by accumulation of sticky material if such is in the container. The arrangement may be reversed, e.g. the shoulders 5, 9 may be formed externally on the bottle neck, and the closure being of bell-shape, the lower flange of the bell resting on and producing the initial distortion of the ring as it rolls over the shoulder 5 and is received inside the bell. Instead of continuous shoulders 5, 7, 9, series of spaced lugs may be provided. According the Specification as open to inspection under Sect. 91, the stopper 1 is inserted in an opening in the wall of the container 3, Fig. 4 (Cancelled), projections 10 abutting against the container wall to prevent the stopper from going too far into the opening. This subject-matter does not appear in the Specification as accepted.

A shaft 12 carries a centrifugal air compressor 11 and a radial flow turbine wheel 10 driven by the exhaust gas from an I.C. engine. The shaft journal 17 is supported in sleeve bearings 22, 23 in boxes 19, 20 of a housing 18. Thrust washers 25, 26, 27 are clamped by a screw 30 and housing part 15a, acting through a spring 29, to retain the bearing sleeve 22. Thrust washers 32, 34 spaced by the spring 33 cause the sleeve 23 to be held against a washer 35. Surrounding the bearings is a pressure-fed oil reservoir 40. The effect of the spring 33 is to restrain the sleeves 22, 23 from rotation while allowing them to float between the housing and shaft on substantial oil films. The spring may be replaced by oil pressure or any other device serving to restrain the sleeves. The bearing is stated to prevent oil film whirl and shaft whip-up to at least 80,000 r.p.m.
