Title: Improvements in and relating to the polymerisation of alpha-olefins
IPC: C08F2/00
Filed: 1969-01-31
Abstract: 1,208,242. Olefin polymerization. CHISSO CORP. 31 Jan., 1969 [3 Feb., 1968; 9 July, 1968], No. 5429/69. Heading C3P. Alpha olefins are polymerized using a catalyst which is prepared by calcining a halide of a trivalent metal with a halohydrate, sulphide hydrate, sulphate hydrate oxysulphate hydrate, hydroxide or hydroxide hydrate of a metal of Groups 1-8 of the Mendeleev Periodic Table, so as to form active groups on the surface of the calcined product, further reacting this with a compound of a transition metal, and then combining this mixture with an organo aluminium compound. In the examples, aluminium trichloride is calcined with magnesium hydroxide, sodium sulphite hydrate, magnesium chloride hydrate, aluminium hydroxide, manganous chloride hydrate, vanadium oxysulphate hydrate, stannous chloride hydrate, chromium hydroxide, nickel chloride hydrate, or ferric chloride, the product then being further reacted with either titanium tetrachloride or vanadium oxytrichloride. This product is then combined with aluminium triethyl, -diethylchloride, or - ethyldichloride and this catalyst system is used to polymerize ethylene, propylene, butylene or an ethylene propylene block copolymer. The polymerization may be carried out in the presence of hydrogen. Certain additives, to prevent agglomeration of the polymer, may be added to the reactants, and exemplified additives are titanium tetrabutoxide, tetraethoxy silane and silicone oil.

Title: Improvements relating to stays and fasteners for the hinged panels of vehicle windscreens, and other hinged or angularly-adjustable panels or the like
IPC: E05C17/30
Filed: 1931-02-21
Abstract: 364,908. Stays; pinless hinges. AUSTER, Ltd., LANE, P., and SMALL, W. W., 174, Barford Street, Birmingham. Feb. 21, 1931, No. 5480. [Classes 65 (i) and 65 (ii).] A telescopic stay for a vehicle windscreen has attached to it an arm which engages a cooperating member to hold the windscreen closed or slightly open; this arm preferably serves also to lock the two parts of the stay together. In the form shown, the windscreen 1, hinged as shown at 2 to the top member of the fixed frame, is supported when open by a telescopic stay comprising a member 11 hinged to the frame and sliding in a member 8 of flanged channel section hinged to the windscreen. The member 11 has a screw pin carrying a nut 13<a> which clamps the parts 8, 11 together to hold the screen in any position. This nut is operated by an arm 13, which has two notches 18, 19 in its lower edge for engagement with a pin or projection 23 on the fixed frame, the projection having a screwed extension with a wing nut to clamp the arm 13 ; the notch 19 is shaped so that the arm 13 can be used as a lever to draw the screen tightly closed by cam action against the pin 23.

Patent GB-784116-A (GB)
Title: Improvements in or relating to electromagnetic relays
IPC: H01H51/06
Filed: 1956-02-22
Abstract: 784,116. Electromagnetic relays. WESTERN ELECTRIC CO., Inc. Feb. 22, 1956 [Feb. 25, 1955], No. 5495/56. Class 38 (5). A relay, Figs. 2, 5, comprises an annular core 1 receiving a coil 2, and a flexible armature 4 pivotally mounted on an angle-section spring 5 by the welding of armature legs 35 to tongues formed by slots 42 cut in the spring, the latter being supported on an insulating spacer 9. A non-magnetic spacer 3 is interposed between the armature and the pole faces 40, 41 of the core. When the coil is not energized the spring 5 and a pair of coil springs (Fig. 3, not shown) which bear against the underside of the armature at its free end, hold the armature away from the pole faces 40, 41, the armature movement being limited by the engagement of a catch 31 with a stop 32. In this condition, a comb bar 6 on the armature holds multiple wire contact springs 15 away from fixed wire contact springs 18. Energization of the coil 2 draws the armature towards the core, the flexible character of the armature causing it to bow, the pivoted end of the armature first moving towards the core and the armature performing a rolling motion on the pole faces until it eventually resumes its straight form. This permits the contacts 15, 18 to engage. The action of the flexible armature ensures a smoother relay operation by enabling the armature pull characteristic to be related to the load characteristic of the contacts (see graphs, Figs. 9, 10, not shown). An insulating cover 38 held by clips 21 may protect the contacts. In a modification, Fig. 8, the core 1 is rectangular. Specification 731,486 is referred to.

Title: Preparation of an amino alcohol
Filed: 1943-04-08
Abstract: 2-Hydroxyethyl-3-amino propyl ether is prepared by the catalytic hydrogenation of 2-hydroxyethyl-2-cyanoethyl ether or ethylene bis-(2-cyanoethyl ether).  The 2-hydroxyethyl-2-cyanoethyl ether is first prepared by reacting ethylene glycol with acrylonitrile in the presence of sodium methylate, the catalyst then being destroyed by addition of concentrated sulphuric acid and the hydroxy cyano compound recovered by distillation; an aqueous solution of the 2-hydroxyethyl-2-cyanoethyl ether with a suspension of Raney nickel catalyst therein is treated with ammonia under pressure and then reduced with hydrogen; the resulting 2-hydroxyethyl-3-aminopropyl ether is recovered by distillation. Similarly, an aqueous solution of ethylene bis-2-cyanoethyl ether, prepared by reacting two mols. of acrylonitrile and one mol. of ethylene glycol in the presence of sodium methylate, is reduced with hydrogen in the presence of Raney nickel catalyst and 2-hydroxyethyl-3-amino propyl ether is obtained together with some n-propyl amine, and ethylene bis-(3-amino propyl ether).  The 2-hydroxy ethyl 3-amino propyl ether may be used in the production of resinous compounds by reaction with dicarboxylic acid. In a disclaimer, reference is made to Specification 571,017.

Title: Adhesive applicator
IPC: B65C9/22
Filed: 1972-02-09
Abstract: 1382164 Gumming labels ADDRESSOGRAPH MULTIGRAPH CORP 9 Feb 1972 [19 Feb 1971] 5993/72 Heading B2L  Label applying apparatus comprises a rotating label supporting suction wheel 14 which moves the labels past a glue applicator head which ejects discrete streams of glue dependent upon the arrival and correct location of a label. Cams 36 on the wheel engage a lever 32 which in turn strikes projections 70 on the piston of a pump 30 allowing adhesive to be ejected against the action of a ball valve. Liquid adhesive enters the pump 30 from a reservoir 24 via a pipe 26. A return pipe to the reservoir is normally closed by a solenoid valve 84. If no label is present on the wheel a photocell 96 opens valve 84 so that when lever 32 actuates the pump 30 adhesive is returned to the reservoir 24 and none is ejected. The movement of lever 32 can be adjusted by means of a screw 90 and thus the movement of the piston in pump 30 and the amount of adhesive ejected is controlled. A dam 104 is provided in the label supporting surface of the wheel and in use lies behind the leading edge of the label. In use this dam causes adhesive to cover the leading part of the label with an even coating.

Abstract: 580,567. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd.; and WILLOUGHBY, E. O. April 4, 1944, No. 6299. [Class 40 (v)] In an overlapping beam navigational system of the type in which the phase of energization of one antenna system is alternated from a phase lead to a phase lag with respect to the energization of another antenna system, two circuits fed with the requisite phase difference from a common source are employed and are followed by a mechanical keying arrangement which feeds the variably phased antenna system from one or other circuit. In the arrangement of Fig. 1 spaced antennµ or antenna systems O1, 02 are fed from the secondary winding 3 of transformer 5 through a line A3, the line connecting the two antennµ introducing a phase difference between their energizations which depends upon their spacing and is indicated as 180 degrees. Transmission lines A1, A2 are fed'from the balanced secondary winding of transformer 5 and are coupled alternately through the keying device 6, described in Specifications 579,873, 580,481 and 580,484 to the line T and the central antenna ,C, the lines A1, A2 preferably being of such a length that they present a high impedance to the transformer 5 when not carrying current. The length of line A3 is so adjusted that the current in antenna O2 lags or leads that in the central antenna C by 90 degrees. If the source of R.F. current is unbalanced the lines Al and A2 may be fed in opposite phase by means of a transformer with two oppositely wound primary windings, the secondary feeding line A3 being more tightly coupled to one primary winding than the other, Fig. 2 (not shown).
