Patent GB-903069-A (GB)
Title: Improvements in the production of rubberlike polymers
IPC: C08F36/04
Filed: 1961-04-04
Abstract: Rubberlike polymers are made by polymerizing a diolefine or a mono-olefine, or a mixture thereof, in the presence of a catalyst comprising a compound of a metal of Group IVa, Va, VIa, or VIII of the Mendel<\>aeeff Periodic Table and an organometallic compound of Group I to III, by dissolving the catalyst in an extender oil which remains in the polymer, and effecting the polymerization in a screw extruder.  Suitable extender oils are mixtures of monoalkylbenzenes and dialkylbenzenes which are obtained as a residue in the alkylation of benzene, and an aliphatic oil sold under the trade name "Dutrex". The polymerization may be interrupted at any point in the extruder tube, e.g. by the addition of an alcohol, or a conventional stabilizer may be incorporated into the polymer at any time.  In Example 1, butadiene is polymerized in the presence of an extender oil containing dissolved therein aluminium ethyl sesquichloride and cobalt dichloride to give a polymer of more than 95% cis-1,4 configuration, whilst in Example 2, a similar product is obtained employing titanium tetrabromide and aluminium triethyl as the catalyst.

Abstract: 660,714. Friction clutches. ELECTROLUX, Ltd. (Aktiebolaget Elektrolux). May 5, 1949, No. 12016/49. Class 80 (ii) [Also in Groups II and VIII] A friction clutch for a household machine (see Groups II and VIII) comprises a disc 29 secured to a motor shaft and an element 37 in the form of a brush which frictionally engages the surface of the disc 29. The element 37 is keyed to the driven shaft by prongs 42 so that it is axially slidable thereon and is urged into contact with the disc 29 bv a spring 36. A ring 44 is supported from a plate 17 on pillars 45 and is positioned so that when it is moved upwardly it engages a brake ring 40a which is secured to the underside of element 37; continued upward movement of the ring 44 moves the element 37 out of contact with disc 29 and simultaneously brakes the rotation of the driven shaft. The ring 44 is urged downwardly by springs 47 and is moved through a system of rods and levers by a hand lever which is so interlocked with a lid of the machine that the clutch can only be engaged to drive the driven shaft when the lid is closed. In an alternative construction the element 37 is moved by a lever which engages a collar, above and integral with the element; in this case no braking ring is used.

Filed: 1944-06-26
Abstract: 582,778. Curving. GREENWOOD, F June 26, 1944, No. 12099. [Class 83 (iv)] Machines for bending angle-iron into rings by means of three rolls have an attachment for preventing lateral deviation during bending. An angle 17, Figs. 1, 2, is fed through the machine by driven main rolls 4, 5 and bending- pressure is applied by an idle roll 8 carried by a spindle 9 mounted in a U-shaped frame 10 vertically adjustable by a screw 12 driven by worm gearing 13 from a hand-wheel 16. The ends of the spindle 9 are further guided by slots 11 in. the main frame. The frame 10 also carries a roller 19, for affording the lateral support, running on a spindle 20 having a lug 20a supported between the arms 22a of a bracket 22 bolted to the frame 10. The upper end of the spindle 20 is journalled in a bracket 21 adjustable to vary the pressure of the roll 19 on the work by a screw 23 and lock-nut 24. By increasing the pressure it is stated that the resulting ring, though still having flanges at right angles, takes a shape suitable for application to a conical surface. When a ring is to be formed with the flange 17b on the inside of the curve, the roll parts 4, 5 are separated sufficiently to admit the flange 17a and a roll is slipped over the roll 8 to engage the inner face of this flange, and support the inner face of the flange 17b against the thrust of the roller 19. Instead of using a slip-on roll, the roll 8 may be replaced.

Title: Fuel lift carburettor for internal combustion engines
IPC: F02M9/133
Filed: 1936-04-29
Abstract: 479,114. Spray carburetters. SCOTT, M. D., and KENT, R. L. April 29, 1936, No. 12221. [Class 7 (iii) Fuel from a float-chamber 4 passes through a passage 21 to a chamber 22, and is drawn by suction through a jet 3 controlled by a suction-actuated piston 13, which is provided with a tapered choke 6 co-operating with a Venturi tube 7. To ensure that the suction in the mixing-chamber will always be sufficient to raise fuel to the float chamber from a low-level reservoir, the tube 7 and choke 6 are shaped so that the difference between the squares of their diameters at various axial positions will, in any position of the parts 6, 7, diminish progressively towards the point of minimum cross-sectional area of the passage between the parts, and increase thereafter at a smaller rate. The fuel is emulsified by air drawn through a passage 31, partly from a port 33 open to the atmosphere, and partly from the space behind the piston, and the emulsion is discharged through an annular groove 30, ducts 29, an annular groove 28, and holes 27 into the Venturi tube 7 on the upstream side of its narrowest cross-section. The suction on the jet may be increased at starting, or when the engine is cold, by turning a cock 36 to restrict the passage 31. The initial movement of the piston may be damped by cutting an annular groove 34 in the cylinder wall, and to provide a small rapid movement of the piston from its lowest position a port 35 communicating with the interior of the cylinder is provided at a point immediately above the rim of the piston. A subsidiary fuel jet 37, byepassing the main jet, is controlled by a needle valve 38. The carburetter is formed in two parts 8, 9 with the groove 30 formed in the upper face of the part 8.

Abstract: 885,556. Endless belt conveyers. UNIVERSAL CORRUGATED BOX MACHINERY CORPORATION. April 6, 1960, No. 12251/60. Class 78 (1). Folded box blanks are fed from a folding machine 53 by means of endless belts 52, 55 on to an endless belt 25 having a conveying run at right angles to the conveying runs of belts 52, 55, the box blanks being retained on the upper conveying run of belt 25 by means of suction applied through perforations in the belt. The perforated endless belt 25 is supported on rollers 22, 23 and on a perforated sheet 16 forming the top of a suction chamber 14, the suction being adjustable by means of a cover-plate 21. As the box blanks are ejected from the folding machine, they strike a deflector plate 72, which is pivoted at 76 to a support bar 64 secured to a back stop plate 33 which is adjustable along fixed bars 28, 29 by means of a screw 36, the speed with which the box blanks strike the plate 72 causing them to be cammed downwardly and causing the plate 72 to pivot upwardly so that the box blanks pass beneath it into contact with the stop plate 33, the plate 72 retaining the box blanks in a folded condition. The belt 25 is driven at a speed slightly less than the speed of ejection of the box blanks from the folding machine so that the box blanks are advanced in overlapping relationship by the belt 25. The box blanks are fed from the belt 25 to a squaring machine such as that described in Specification 832,733.
