Abstract: 1,221,859. Portion forming and bagging apparatus. A.M.F. Inc. 27 Sept., 1968 [27 Oct., 1967], No. 45992/68. Heading B8C. [Also in Division G1] Small pieces of material are formed into portions of predetermined weight and these portions are transferred individually into bags. Portion forming apparatus.-The material is stored in a hopper 12 which can be vibrated by vibrator 28. The hopper is divided by vertical baffles so that the flow to outlet 44, when the hopper is vibrated, remains substantially independent of the amount of material in the hopper. Outlet 44 can be closed by a gate 74. A scale pan 106 is mounted below outlet 40 and is arranged so that when the desired weight is reached a switch is actuated and gate 74 is closed by a solenoid and vibration of the hopper is stopped. Bag filling apparatus.-The operating sequence is controlled from motor 122 and gearbox 124 which drive conveyer 224 which carries the filled bags 144 in holders 230 and also drives arm 132 via a crank. When the scale pan 106 is filled to the correct weight and the switch 88 is actuated, air blast unit 180 is actuated to blow open the end bag hanging on supports 206, 208 and held in place by spring-biased members 214, 216. Motor 122 is also actuated and rotates the crank to move arm 132 downwards and tip up the scale pan 106, emptying the portion of material into funnel 156 and thence into bag 144. As the arm 132 moves downwards it moves the funnel 156, which has a sliding mounting with it and forces arm 166 which is pivoted on an arm attached to the funnel and attached to pinion 174 to rotate and force material from the funnel into the bag. When the bag has been located in the carrier 230, the conveyer is moved up by one step so that the next carrier is positioned ready for the next bag.

Title: Rolling Mills
Inventor: NEUMANN KARL
IPC: B21B31/04
Filed: 1967-10-18
Abstract: 1,181,166. Rolling. MOELLER & NEUMANN G.m.b.H. 18 Oct., 1967 [27 June, 1967], No. 47378/67. Heading B3M. A rolling mill includes prestressed frame parts 1 and 2, and hydraulic actuators 5 and 17 for bending the backing or work rolls of the mill to counteract their deflection under load. Upper actuators 5 extend between pins 12 on a roll bearing ring, and a beam 4 on the frame part 2, their operation thereby being unaffected by screwdown movements. Each tie rod 3 is surrounded by a screwdown mechanism including a fixed sleeve 20 and an adjustable nut 21 splined to a sleeve 27. When pressure is released in the space between a piston 36 and cylinder 35, the sleeve 27 is rotatable through gearing 26, 25 and 24 from a shaft 23 to effect screwdown movements. A clamp nut 30 permits independent adjustment of the effective length of the tie rod when the pressure is released. The nut 30, when coupled by a pin 31 to a portion 27a of the sleeve 27, also ensures that the tie rod length is adjusted simultaneously with screwdown adjustments. Hydraulic cylinders 40 and 41 balance the weight of the frame ports 2 when such adjustments are being made.

Title: Video arrangements
IPC: H04N7/14
Filed: 1969-09-26
Abstract: 1,219,067. Automatic exchange systems; television; companding. TELEFONAKTIEBOLAGET L.M. ERICSSON. 26 Sept., 1969 [9 Oct., 1968], No. 47597/69. Headings H4F, H4K and H4R. In a picture telephone or telegraph facsimile system, the video signal is subjected to compression (or expension) before being applied to line (or to a picture tube). Compression here, means that small amplitudes of the video signal are amplified to a greater extent than are large amplitudes thereof. The use of companding allows low-pass filters having steep slopes to be utilized, whereby the advantage of high resolution provided by such a filter is retained, but the disadvantage of overshoot signals, viz. peaky transients at the pass band edge is mitigated. One particular disadvantage of overshoot signals is that at low amplitude levels the overshoot may enter the negative region and thereby be confused with a sync. signal (Fig. 1b, not shown). Another disadvantage is that at high amplitude levels the overshoot may cause grey lines to be erroneously produced at the receiver. These problems are usually overcome by utilizing filters having a gentle slope but as such filters cannot provide sharp resolution (Fig. lc, not shown), the possibility of good facsimile reproduction using a picture telephone is markedly reduced. As shown, video signals produced by scanning a subscriber's face with camera C are normally supplied, via adder S1 and gentle slope filter F1 to line, a sync. signal produced by camera C being additionally supplied to adder S1. In the receiver the sync. signal is retrieved by S2 and used to control picture tube T to which the video signals are applied. For facsimile working, the contacts K1, K2, K3 are switched-over so that a compression amplifier A1 and a steep slope filter F2 are interposed in the path of the transmitted video signals while an expansion amplified A2 is inserted in the path of the received video signals.

Title: Oil-containing vessels
IPC: B65D88/78
Filed: 1974-10-01
Abstract: 1482638 Underwater storage tanks FOSTER WHEELER POWER PRODUCTS Ltd 1 Oct 1974 [11 Oct 1973] 47613/73 Heading E1H An underwater oil storage tank 12, associated for example with an oil production platform 26, has an oil conduit 42 leading to the top of the tank, and a water conduit 30 leading to the bottom of the tank. The conduits 42, 30 may be located within the legs 16, 18 of the platform 26. The pressure within the tank is kept below the pressure of the water outside the tank by means of a pump 36 which maintains the water level 54 in the conduit 30, below the outside water level 52. This reduces the risk of leakage of oil from the tank 12. Water is removed by the pump 36, or allowed to enter through valve 34, to automatically keep the water level 54 constant below the surrounding water level, for example at 14 metres below the. water level 52. The oil level in the conduit 42 varies between the limits A and B according to the amount of oil in the tank, and the level may thus be used as an indicator of the quantity of oil stored.

Title: Cyclopolysiloxanes
IPC: C08G77/04
Filed: 1962-12-18
Abstract: The invention comprises compounds of the formula  <FORM:0980103/C3/1> where n is 0 or 1.  They are prepared by the reaction of tetraphenyldisiloxane diol-1,3 or hexaphenyltrisiloxane diol-1,5 with a phenyl triphenylsiloxydihalosilane, in the presence of a hydrogen halide acceptor, e.g. a tertiary amine, particularly pyridine. The reagents are dissolved in an inert solvent, e.g. THF, n-hexane, ether, toluene.  The hydrohalide precipitate is removed, then the solvent, and the product is crystallized. Polymers with recurring units <FORM:0980103/C3/2> where n is 0 or 1 are prepared from the compounds (I) by heating them alone at 250-350 DEG  C., or, preferably, with a catalyst at 150-180 DEG  C., the monomer being molten.  A suitable catalyst is a 0.01-1% solution of KOH in octamethylcyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer.  The polymers have MW's of 10,000 to 5,000,000 and are clear gums, soluble in benzene and toluene. Copolymers may be made in a similar manner from the compounds (I) with themselves or other cyclopolysiloxanes, e.g. those of Specifications 980,101, 980,102, 980,104, 980,105 980,106, 980,107, 980,108 and 980,109. The homopolymers of units (II) cannot be cured, but copolymers containing vinyl or adjacent methyl groups can be cross-linked by conventional free radical (e.g. peroxide) curing agents, or by irradiation, e.g. with 50,000 to 2,000,000 eV electrons.  Fillers may be added before curing. Suitable filler include silica aerogel, fumed silica, precipitated silica, TiO2,CaSiO3,CaCO3, FeO3, Cr2O3, CdS, asbestos, glass fibres, carbon lithopone, and talc.  The examples describe the preparation and polymerization of both the compounds (I), and the encapsulation of transformers in the polymers, and the preparation of copolymers of the trisiloxane (I) with hexaphenyl cyclotrisiloxane and of the tetrasiloxane (I) with octamethyl cyclotetrasiloxane, and the cure of the last.
