Title: Apparatus and method for casting articles
IPC: B28B1/26
Filed: 1965-04-22
Abstract: 1,064,247. Slip casting apparatus. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. April 22, 1965 [April 22, 1964], No. 17082/65. Heading B5A. [Also in Division B8] An automatic plant for the production of articles by slip casting, e.g. from ceramics material, comprises a conveyer 10, Figs. 1A and 1B, which conveys mould cores, and a conveyer 12 which carries tub moulds, the conveying being intermittent with the mould parts passing through stations where (i) a core setting machine 30 deposits a core in each tub mould; (ii) a funnel handling machine 34 places a funnel 35 on the completed and clamped mould; (iii) slip is delivered via the funnel 35 by a slip pouring machine 38; (iv) funnel 35 is removed by machine 34; (v) the core is removed by a machine 48; (vi) the casting is dried by a dryer 50; (vii) the castings are removed by a transfer device 52; and (viii) the moulds are dried by a dryer 26. The core setting machine (30), Fig. 2 (not shown), comprises a frame (72, 74, 76) which runs on rails (80) and straddles conveyers (10), (12). Vertically reciprocable lifting lugs (96) cooperate with lugs (99) on a core (14) to lift the latter clear of a hook (25), the hook being swung to one side by a device (118), see also Fig. 10 (not reproduced), so that core (14) may be lowered into a tub mould (20). At the same time a dust box (136) suspended on arms (138) is raised to dust the following core (14), Fig. 3 (not shown). A device (170) clamps the core in position within tub mould (20) by pressing downwardly on the arm (172) of a clamp (166), see also Figs. 8 and 9 (not reproduced). The position of core setting machine (30) relative to the mould parts is accurately adjusted by devices (198), Figs. 2, 12, 13 and 14 (not shown), each of which comprise a rockable cross-bar (202). The cross-bar (202) is lowered to contact a pin (204) on conveyer (12), which when machine (30) is correctly positioned enters a notch (203), but otherwise rocks bar (202) and thereby displaces pistons (220), (221) which actuate a motor to drive machine (30) in the appropriate direction. The slip pouring machine (38), Fig. 11 (not shown), is adjustable in position relative to core removal machine (48), Figs. 15 and 16 (not shown), so that the setting period for the slip may be varied. The machine (48) is essentially the same as core setting machine (30), but incorporates an article marking device (276) and a core release mechanism (296), for details of which see Figs. 17-19 (not reproduced), which admits air via a bore (303), Fig. 16 (not shown), in core (14) to the space between the latter and the casting. As shown, the plant comprises pneumatically powered driving mechanisms, but these may be hydraulically or electrically powered. Holes may be punched in the castings at a further station 60, Fig. 1B.

Title: High frequency line repeaters
IPC: H01J25/34
Filed: 1948-06-25
Abstract: 660,362. Electric discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. June 25, 1948 [Aug. 14, 1947], No. 17109/48. Class 39 (i). Apparatus for amplifying high-frequency energy comprises a pair of wave-guides 27, 28, Fig. 3, means in guide 28 for emitting electrons into guide 27, the high-frequency energy being applied to both guides in such a way that it is delayed in guide 28 relatively to the energy in guide 27 so that more electrons from cathode 24 are emitted into guide 27 when the electric field therein is decelerative and less electrons when the electric field is accelerative. Preferably guide 28 is fed over a path 26 that is half a wavelength longer than the path feeding guide 27. The electrons are emitted from a hot cathode 24. The dividing wall 21 is preferably biassed so that when the electrons are decelerated in guide 28 they are just cut off from entering guide 27. The guides 27, 28 may be coiled to helical form, Figs. 4, 5 (not shown). The apparatus may be duplicated by branching from a single wave-guide, Fig. 6. According to the Specification as open to inspection under Sect. 91 a single wave-guide is formed in a spiral, Fig. 7 (Cancelled), and electrons from a source 49 and gated by an appropriately-energized grid 52 pass through windows in the spiral when the field is decelerative so as to give up energy to the wave. In Fig. 8 (Cancelled), the electrons are emitted from a central source 54. This subject-matter does not appear in the Specification as accepted.

Filed: 1943-10-20
Abstract: 592,489. Velocity-modulated tubes. WESTERN ELECTRIC CO., Inc. Oct. 20, 1943, No. 17309. Convention date, June 28, 1941. [Classes 39 (i) and 40 (v)] In high-frequency apparatus in which a beam from an electron gun comprising a cathode 23 and an accelerating electrode 24 passes through input and output gaps and a drift space in a resonator tube 10 of a velocity modulation type to a collector electrode 30, this electrode may be maintained at a relatively high positive potential so that oscillations are set up and the apparatus can be used for transmission or the collector electrode may be maintained at a lower potential and the feed-back between the input and output gaps reduced so that the apparatus can be used as a detector for reception. The feed-back may be reduced by reducing the beam current by lowering the potential of the accelerator electrode 24. It may also be reduced by alteration of the transit time in the drift space by altering the potential between the cathode and the resonator. The tube 10 which may be of the kind described in Specification 555,162 is provided with two wave guides 19 and 20 acting as aerials and communicating with the resonator of the tube by windows in the latter. The wave guides are slotted to give out or receive radiant energy. The apparatus is changed between receiving and transmitting by throwing over the three part switch 37, 41, 44, controlling the electrodes 24 and 30 and the transmitter telephone 34 and receiver 45. In the receiving position the electrode 30 of the tube is connected to the grid of an amplifying valve 35 and through the coil 39 with the cathode 23 of the tube.

Title: A method of producing 1,2-siloxacycloalkanes
IPC: C07F7/18
Filed: 1963-05-03
Abstract: A method for the production of 1,2-siloxa-alkane compounds comprises the reaction of a silane (A) of formula RaSi(O-CH2-CH = CH2)4-a where a is 0, 1, 2 or 3, with a silane (B), HSiRbX3-b where b is 0, 1 or 2, and R is a saturated hydrocarbon group in the presence of a catalyst promoting the addition of olefinically unsaturated compounds to Si-H groups.  Temperatures above 50 DEG C., preferably between 80 DEG  and 90 DEG  C., are suitable.  An autoclave may be necessary. The silanes (A) and (B) may be represented by single compound, e.g. R12Si(H)OCH2CH = CH2 carrying both an Si-H group and an alkenoxy group, the remaining substituents, (R1), being halogen, or alkoxy, allyloxy or hydrocarbon groups.  In this case the reaction is performed by dripping reactant plus catalyst into a heated vessel. The products may be cyclic monomers <FORM:1036089/C3/1> or cyclic or linear polymers of unit -SiR2-(CH2)3-O-The latter decompose on heating into the monomers, while the monomers slowly polymerize at room temperature.  In solution a state of equilibrium is established. Examples describe the reactions of trimethyl allyloxy silane with methyldichlorosilane and with triethoxysilane, using H2PtCl6 in alcohol, and Pt on carbon, respectively, to give 1-chloro-1-methyl- and 1,1-diethoxy-1,2-siloxacyclopentane, on distillation from baths at 250-350 DEG C.  With silicochloroform, using H2PtCl6 and triethylene diamine, a polymer of 1,1-dichloro-1,2-siloxacyclopentane was obtained which was not distilled.  A further example describes the cyclization of methyl allyloxy chlorosilane prepared from allyl alcohol and methyldichlorsilane.
