IPC: B60F3/00
Filed: 1972-08-23
Abstract: 1336838 Amphibious vehicles SCHOTTELWERFT JOSEF BECKER KG 23 Aug 1972 [17 Nov 1971] 39275/72 Headings B7A and B7V A floatable land vehicle having a propulsion system for travel on land has an additional motor 17 for a propeller 12 having a vertical swivel axis 13 at least when in its operative position, and tiltable around a horizontal axis. A swivellable propeller part 15 carries a propeller screw 16 driven by the motor 17 which is mounted on a fixed part 14 of the propeller. The swivellable part 15 is actuated by a control motor 18. The propeller which may be tilted about bearing blocks 22, 23, Fig. 2, is secured in the vertical position by a releasable clamping bracket 29. The propeller may be winched into the upwardly tilted horizontal position by reciprocating movement of a hand lever 40 acting through drum 35 and a cable or chain 34 and held by a ratchet and pawl 37, 39 or a catch 41 engageable behind a cog 43 on propeller shackle plate 19. The tipping action may alternatively be accomplished by an electrical, hydraulic, or pneumatic driving system. The motor 17 may be driven by an hydraulic motor 45 which also drives a fan 44 of the vehicle. In a modification, Fig. 4, the propeller (60), Fig. 5 (not shown), is mounted to be tilted sideways about bearing block 63 by means of a cable 67 co-operating with a pulley system 66, 68. A cylinder 79 housing two pistons is actuated so that rods 80, 81 open or close catches 76, 77 which secure the propeller in the operative vertical position. The catches may alternatively be electrically or mechanically actuated as may motors 17, 18 be driven pneumatically, or electrically, or by internal combustion engines.

Title: Fluidic timing chain for the interlocking of successive steps in a control sequence
IPC: G05B19/44
Filed: 1976-09-30
Abstract: In addition to a priming stage (11), the timing chain has at least two stepping modules (12, 13), of which each has a 5/2-way valve constructed as a pulse valve. The 5/2-way valve (53) is constructed and wired in such a way that during priming by a setting signal of a preceding stage (11) it is held by the continuing signal at the associated signal input (29) in a position in which its associated signal output (25) receives no compressed air. The timing chain (10) therefore remains stationary at the particular point even in the event of a permanent signal of a defective limit switch, without skipping a step and running on. <IMAGE>

Title: Process for the polymerisation of propylene
IPC: C08F110/00
Filed: 1961-11-17
Abstract: Propylene is polymerized using a catalyst obtained by reacting an organometallic derivative of a Group I, II, III or IV metal with the hydrocarbon-insoluble portion of a complex compound obtained by the reaction of a transition metal compound with a compound H2X where X is selenium or sulphur. The hydrocarbon-insoluble portion of the complex compound is produced by reacting hydrogen selenide or sulphide with the transition metal compound, if desired in the presence of an inert hydrocarbon, washing the product in the absence of atmospheric humidity with a dry solvent and drying it under a vacuum. The preferred transition metal compound is titanium tetrachloride and the preferred organometallic compounds are alkylated, possibly halogenated, aluminium derivatives such as triethyl aluminium. The polymerization may be in bulk or in a solvent. In one of the examples the polypropylene obtained using a hexane solvent is filtered from the solvent, washed with dry hexane, treated with an alkaline solution of hydrogen peroxide, subjected to treatment with water vapour in the presence of NaOH and the purified polymer extracted wth boiling heptane.

Title: Process for producing organosilicon compounds
IPC: C08G77/08
Filed: 1960-12-06
Abstract: An organosilicon compound of the formula <FORM:0945810/C3/1> wherein each R is a monovalent hydrocarbon radical (saturated or unsaturated) with or without halogen, amino, hydroxyl, cyano, carbalkoxy, alkoxy or aryloxy substituents, R1 is H or an alkyl radical and n is at least 1, is condensed in the presence of a catalystic amount of lithium hydroxide, diorganosilanolate or diorganosiloxanolate. The organosilicon lithium compounds have the formula: <FORM:0945810/C3/2> wherein R1 1 is Li or H.  The catalyst is usually used in amount to provide from 0.001 part to 10 parts (by weight) per 100 parts of the hydroxy silane or siloxane.  The process, which can be conducted in an inert solvent, is usually conducted at 25 DEG  to 175 DEG C. and the by-produced water or water and alcohol is preferably continuously removed; after completion of the reaction, the solvent and catalyst can be removed.  The starting materials of formula (1), in which n is 1 to 7, yield cyclics (R2SiO)p, where p is 3 to 7 and higher molecular weight linear polymers, the yield of cyclics being 40% when a solvent is used; the materials in which n is at least 8 yield linear OR1-terminated siloxanes of at least 16 siloxane units.  The process is also applicable to the co-condensation of alkoxysilanes with hydroxy siloxanes of formula (1) in which n is at least 8.  In examples (I) a mixture of HO[(CH3)2SiO]20H and LiOH was heated at 150 DEG C. to yield a gum free from lower cyclics; and (II) an oil of the formula: <FORM:0945810/C3/3> (Me=methyl, Vi=vinyl) and LiOH were heated at 85 DEG C. to yield a gum, which was mixed with SiO2, an ethoxy-terminated dimethylpolysiloxane, iron oxide and a peroxide curing agent and cured to yield an elastomer.
