Title: Improved process of polymerising olefines
IPC: C08F10/00
Filed: 1963-07-02
Abstract: Polymers of olefines, e.g. ethylene, are made by effecting the polymerization of the monomers in the presence of a catalyst comprising (a) a metal, hydride, or organometallic compound of a metal of Group IVb, Vb, or VIb of the Periodic Table, (b) a halide of a metal of Group IVa, Va, or VIa of the Periodic Table, (c) a halide of an element of Group III of the Periodic Table, and in the presence of 0.5 to 1.5 gram mols. of water per gram atom of the metal present in (b).  The polymerization is generally effected in a solvent in which at least part of the water is dissolved.  The water may also be present in the monomer.  The exemplified catalyst is TiCl4-Sn(C4H9)-AlCl3.  Specification 856,815 is referred to.

Abstract: 1,205,834. Expanding-pulley gearing. DAIMLER-BENZ A.G. 31 May, 1968 [2 June, 1967], No. 26249/68. Heading F2D. [Also in Division F1] In a variable-speed drive for the auxiliary items of an internal combustion engine the cooling fan 12 is driven by the crank-shaft 10 through expanding-pulley gearing 11 and drives a multigroove pulley 13 connected to the other items by belts, the gearing 11 being arranged to effect, by centrifugal control, an upward speed change as the crank-shaft speed falls to a low value, and conversely. The gear consists of fixed cone discs 20, 35 and movable discs 25, 42 loaded by springs 29, 40 respectively, the disc 25 being integral with a casing 23 while the disc 35 is integral with pulley 13. Casing 23 houses a fixed piston 21, the space 50 between the members being filled with liquid, the centrifugal head generated in which displaces casing 23 and disc 25 to vary the ratio of gear 11 in accordance with the speed of crankshaft 10. In a first modification, Fig. 2 (not shown), the piston (43) is a sheet-metal pressing incorporating a peripheral bellows seal (44), while in a second modification, Fig. 3 (not shown), centrifugal control is effected by pivoted weights (59) mounted within pulley 13 and varying the axial spacing of the associated core discs.

Title: Electron-beam evaporator
IPC: H01J37/305
Filed: 1977-06-23
Abstract: The electron beam evaporator is used for vapour deposition, especially of sublimable substances, in vacuum vapour deposition systems. The electron beam evaporator in this arrangement comprises a container (3), which has an opening, for the material to be evaporated and an electron beam source (24) for supplying the heat of evaporation to the container (3). So as to be able to employ an electron beam evaporator of this type to evaporate pulverulent material even if present as relatively thick layers, continuously and without squirting and dusting over a prolonged period, it is proposed according to the invention that there be arranged in the beam path between the electron beam source (24) and the container (3) an impingement plate (4) for the electron beam (23). The underside facing away from the impingement side of the impingement plate (4) faces the container cavity. The impingement plate (4) covers the container (3) while leaving free an outlet orifice (5) for the vapour beam. <IMAGE>

Title: Improvements in or relating to the carbonisation of coal, wood, peat, and other ligneous material
IPC: C10B27/06
Filed: 1927-10-06
Abstract: 302,437. Gas Light & Coke Co., Hollings, H., and Neath, J. Oct. 6, 1927. Ascension pines.-In operating intermittently charged gas retorts or ovens the pressure is automatically controlled in any one, or in all the retorts so as to suit the requirements at any particular stage, of carbonization and during charging and discharging. A rotary shaft 6 extending down a row of ascension pipes 5 carries cams 7 provided with a " free wheeling " action each of which controls the pressure in one of the retorts. These cams each rotate one revolution in the period during which the charge is being heated, and serve to raise or lower the dip pipe seal or to vary the load on a. gas governor so as to accommodate the sudden evolution of gas just after the retorts are charged and maintain the requisite pressure during the subsequent slower period of gas production. Each cam comprises one portion 12, Fig. 9, dropping quickly to a minimum where it meets a circular portion 13, 14 corresponding to the slow evolution of gas, and terminates in a circular portion 15 corresponding to full immersion of the dip pipe. Each cam contacts with a lever 17, an extension 23 of which is hinged to bear on one or other of the portions of the cam, a slotted link 16 connecting the lever 17 with a forked lever 11 which raises or lowers the dip pipe 1, Fig. 5, which terminates at its top in a water seal 52 and at its bottom in an hydraulic main 2, the chamber 64 leading to the ascension pipe. In Fig. 7 is shown a fixed downcast pipe 65 on which moves a dip pipe 1 having an annular flange 47 in a seal 52, and connected by an internal lever 60 with the lever 11, the gas in this case passing directly to the hydraulic main and through an annular space 66 to the upper surface of the seal 52. In. one modification the lever 11 is connected with a governor which controls a throttle valve in the ascension pipe; and in another modification the pressure is controlled by varying the level of the liquid seal in the hydraulic main by an adjustable overflow pipe or weir.

Abstract: 1319249 Gonioscope H CARDONA 4 June 1970 [5 June 1969] 27120/70 Heading G2J A gonioscope for examining the angle of the anterior chamber A of an eye E comprises a lens 10 having a concave surface 14 adapted to engage the cornea C of the eye and a spherical convex surface 18, the axes a-a and b-b of the two lens surfaces intersecting at an angle of about 55 degrees, and a light guide 12 one end 12a of which is joined to the surface 18 at a location spaced from the axis b-b and to one side of the plane of the axes. The surface 14 may have a curvature rather less than that of the cornea so that it contacts first the centre of the cornea and thereafter the remaining surface, so that no air bubbles are trapped. Light from a source (24) such as a projector, Fig.1 (not shown), may be directed via the guide 12, which may comprise a fibre optic cable 20, along a line c-c which lies in a plane perpendicular to the plane of the axis a-a and b-b and makes an acute angle with the plane of the axes. The region to be examined is not directly illuminated, thereby avoiding undesirable reflexion effects, but may be viewed, via the convex surface 18, along the line d-d; the lens may provide a magnification of 2X. Near its point of attachment to the lens the guide 12 may have a substantially right-angled bend from which it may increase in thickness to merge with a portion (12b) which may have a hand-grip. There may be a plug (not shown) mating with a plug on a fibre optic cable (22) connected to the light source (24). Alternatively the handle may comprise a small flashlight. It is advantageous to coat all surfaces of the gonioscope, other than 14 and 18, with a light-absorbing material, in the region of the bend the guide 12 is preferably silvered beneath the absorbent coating.
