Title: Multiple storey garage
IPC: E04H6/24
Filed: 1962-09-14
Abstract: 989,859. Mechanical garages. STAHLWERKE SUDWESTFALEN A.G. Sept. 14, 1962 [Sept. 15, 1961], No. 35159/62. Heading B8E. In a multistorey garage of the kind in which a vehicle is placed on a trolley 4 at the entrance b and is taken, still on the trolley, by a lift 1 to a selected storage site adjacent the lift shaft, each floor has at least one storage site with space for two or more cars on the same side of the lift and the trolleys are equipped for coupling together so that a trolley being moved between the lift and the immediately adjacent storage space of a multi-space site can be coupled to a second trolley for simultaneous movement of the latter between the said space and the neighbouring space on the same site. At the entrance b a vehicle is driven up a ramp 3, Fig. 2 (not shown), on to a waiting trolley which rests on two parallel beams 7 which, after the vehicle has been moved, can be swung away to allow another trolley from the basement store f to be positioned. The loaded trolley 4 is taken into the lift by operation of an hydraulic actuator 13, Fig. 5, which moves a carrier 18 in the lift towards the trolley 4. A projection 24 from an endless chain mounted on the carrier 18 then engages a mating projection on the trolley and the chain and hydraulic actuator are operated to move the trolley. At the selected storage site the trolley is run off and if the site comprises two or more car spaces and the space adjacent the lift is occupied, the entering trolley pushes the trolley already present to the next space on that site. When the two trolleys contact each other, spring catches 27, Fig. 8, on the undersides of the trolleys automatically couple them together. In retrieval, the two or more coupled trolleys move together until one of them is in the lift at which point a release lever 31 for the catch 27 of the leading trolley is operated by a fixed trip member 30, Fig. 5, in the parking site to release the coupling. If the trolley to be retrieved is not the leading trolley, it will be necessary to store the latter temporarily while the required trolley is removed. To facilitate this the lift 1 is multitiered, e.g. for the system of Fig. 1 in which there are two parking spaces on every site the lift has two superimposed compartments 32, 33 each with a platform carrier 18 so that one of these can remove and temporarily store the leading platform from a storage site and the other be subsequently used to retrieve the second platform on that site. Other arrangements than that of Fig. 1 are possible and examples (Figs. 12 to 14, not shown) are given. In these alternative arrangements there may be single-space storage sites on one side of the lifts and multi-space sites on the other; in system using more than one lift, two lifts may serve a three-or-more-space parking site located between them. In one embodiment (not illustrated) there is a single lift rotatable about a vertical axis and a plurality of parking sites surround it.

Title: Improvements in the processes for polymerising ethylene with the aid of organo-metallic catalysts
IPC: C08F110/02
Filed: 1958-11-03
Abstract: Ethylene is polymerized with the aid of a Ziegler catalyst which is prepared by contacting the catalyst components with stirring at a temperature of from -10 DEG  to -100 DEG C., the stirring being continued whilst the temperature rises to room temperature. The components may be mixed in any order preferably in solution in an inert hydrocarbon solvent, e.g. heptane, and may be mixed in the presence of an inert carrier such as pulverised polyethylene. The catalyst components may be titanium tetrachloride, vanadium tetrachloride, zirconium tetrachloride and aluminium tri-isobutyl, diethyl hydride or triethyl and the ratio of aluminium compound to transition metal compound may be from 0,3 to 3.  In the examples ethylene is polymerized in solution in heptane at 5 atmospheres pressure to form granules of molecular weight below 100,000.ALSO:A Ziegler catalyst is prepared by contacting the catalyst components with stirring at a temperature of from -10 DEG  to -100 DEG C., the stirring being continued whilst the temperature rises to room temperature.  The components may be mixed in any order, preferably in solution in an inert hydrocarbon solvent, e.g. heptane, and may be mixed in the presence of an inert carrier such as pulverised polyethylene.  The catalyst components may be titanium, vanadium or zirconium tetrachlorides and aluminium tri-isobutyl, triethyl or diethyl hydride and the ratio of aluminium compound to transition metal compound may be from 0.3 to 3.

Title: Improvements in or relating to fountain pens
IPC: B43K5/06
Filed: 1935-12-20
Abstract: 451,168. Fountain pens. HEBBORN, H., and SCHLICKSUPP, (trading as HEBBORN & CO., H.), 49, Domstrasse, Cologne, Germany. Dec. 20, 1935, No. 35295. Convention date, June 29. [Class 146 (iii)] In a fountain pen having means for sealing the ink reservoir and having a pistonrod consisting of parts screwed into each other, the thicker end of the piston-rod is mounted so as to be rotatable and longitudinally movable in a guide - sleeve located in the upper end of the barrel, and is provided with an annular packing-surface which co-operates with a corresponding seat arranged in the guide-sleeve to seal the ink reservoir to the outside 1 and means is provided to retain the piston-rod part in the sealing position. The piston a is carried by a rod h provided with an enlarged head h<1> screwing into a telescopic tube g, which in turn has a head g<1> screwing into a tube g<2>. The tube g<2> passes freely through a guidesleeve d and is rotated to advance or retract the piston, by a head f, while the piston is being retracted the frictional drag presses the head f on to the outer end of the sleeve d, but air can escape from behind the piston through a recess in the edge of the head f. When the piston is completely retracted a protective cap e is screwed on to the head f and withdraws it sufficiently to press a packing-ring c against the inner end of the sleeve d, and thus completely seal the barrel. The piston-rod may be in four or more telescoping parts.

Title: Esters of thiophosphoric acids containing sulphoxide groups
IPC: E04B2/02
Filed: 1957-11-13
Abstract: The invention comprises thiophosphoric acid esters of the general formula <FORM:0834354/IV (b)/1> wherein R1 is a C1-C4 alkyl radical, or halogen, e.g. chlorine or bromine, R2 is a C1-C4 alkylene radical, X is oxygen or sulphur, at least one X being sulphur, and R3 and R4 are C1-C4 alkyl radicals.  They may be obtained by oxidizing the corresponding sulphides of the formula <FORM:0834354/IV (b)/2> with hydrogen peroxide in the presence of a water-miscible inert organic solvent or with nitric acid.  The reaction using hydrogen peroxide should generally be carried out at slightly elevated temperature, e.g. up to 50 DEG  C. and preferred solvents are formic, acetic, propionic and butyric acids.  Examples are given for the production of the following compounds: (1) p.Cl.C6H4.SO.CH2S.P(O)(OC2H5) 2, (2) p.CH3. C6H4SO.CH2SP(O)(OC2H5)2, (3) p.CH3.C6H4. SO.CH2CH2SP(S)(OC2H5)2, and (4) p.CH3C6 H4SO.CH2SP(S)(OC2H5)2.  The products have good pesticidal properties (see Group VI). The sulphide-group-containing starting materials of the above formula may be obtained either by (a) reacting alkarylmercaptoalkyl halides with salts of thions or dithiophosphoric acid diesters, (b) reacting alkarylmercaptoalkyl mercaptans with the appropriate phosphoric- or thio-phosphoric acid diester halides, or (c) reacting alkarylmercaptoalkanols with thiophosphoric acid diester halides, the products thus obtained being thiono- or dithio compounds in (a), thiols or dithio compounds in (b), and thiono compounds in (c).ALSO:An insecticidal composition comprises a thiophosphoric acid ester of the general formula <FORM:0834354/VI/1> wherein R1 is a C1-C4 alkyl radical, or halogen, e.g. chlorine or bromine, R2 is a C1-C4 alkylene radical, X is oxygen or sulphur, at least one X being sulphur, and R3 and R4 are C1-C4 alkyl radicals (see Group IV (b)) and a solid or liquid carrier.  Specified carriers are chalk, talc, bentonite, water, alcohols and liquid hydrocarbons.  Known pesticides may also be present.  A suitable composition is obtained by dissolving the compound p.CH3.C6H4.SO.CH2. SP(S)(OC2H5)2 in dimethyl formamide, adding benzylhydroxydiphenyl polyglycol ether as emulsifier and then diluting with water.
