Abstract: 711,944. Filters. NORDELL, C. H. Oct. 30, 1952 [Dec. 17, 1951], No. 27340/52. Class 46. [Also in Group II] Apparatus for screening solids from a liquid comprises a stationary screen through which the liquid flows, a rotatable cylinder spaced from the front of the screen, tines carried by the cylinder, and mechanism for advancing and retracting the tines relatively to the cylinder as the latter rotates such that the tines are fully advanced as they sweep past the screen to cooperate with the screen and remove solids therefrom and transfer these solids to a place away from the screen, and are fully retracted when they are remote from the screen. The screen comprises flat metal ribbons 25, Fig. 1, in slots 20, 23 and held taut individually by springs 31 connected to short strips 28 in slots 24. Solids collecting on the influent (right-hand) side of the screen are removed by tines 79 secured to a bar 95, Fig. 8, within a cylinder 82 rotating anticlockwise, and are carried up to a comb 89 where they are comminuted by co-operation of teeth 87, on cutting members 86 secured between spacers 84 on the cylinders 82, with recesses 94 on the comb. The bar 95 is pivoted between crank arms 99 (one at each end of the cylinder) each rotating about a bolt 103, the arrangement being such that when one set of tines 79 is fully advanced and engaged between the ribbons 25, the other set 79a is fully retracted and located opposite the slots 94. Fig. 8 shows an intermediate position. The cylinder is driven through worm gearing by a motor 59, Fig. 1. Nozzles may be provided in a pipe extending along the frame member 9 for supplying air or water to force solids up the screen to the tines. In a modification (not shown) the cutting members 86 and comb 89 are omitted, the solids being removed from the cylinder at the top by a stripper plate from which they fall onto a transversely-moving conveyer belt for discharge outside the channel 3.

Title: Organo-substituted borine carbonyls and their production
Inventor: REPPE WALTER
IPC: C07F5/02
Filed: 1959-08-12
Abstract: Polymeric products may be obtained by heating a borine carbonyl [B(R1R2R3)CO]n where n is 1, 2, 3 or 4, R1, R2 and R3 may each represent an alkyl radical of 2 to 18 carbon atoms, a cycloalkyl radical with 5 to 12 carbon atoms or an aralkyl radical, and R1 and R2 may also be hydrogen.  Thus dimeric boron alkyl carbonyls may be heated to 150 DEG  to 350 DEG C.  For example the boron triethyl or boron tri-n-propyl carbonyls are heated at 250 DEG C. for 2 hours giving a polymer of molecular weight 1,200.ALSO:The invention comprises borine carbonyls of the formula [B(R1R2R3)CO]n in which n is one of the numbers 1, 2, 3 or 4, R1, R2 and R3 each represents an alkyl radical with 2 to 18 carbon atoms, a cycloalkyl radical with 5 to 12 carbon atoms, or an aralkyl radical derived from an ethyl radical by substitution of one or more, preferably two, hydrogen atoms by phenyl or toluyl radicals or by substitution of two hydrogen atoms by methyl and phenyl or toluyl radicals, or R1 and/or R2 may also represent hydrogen atoms.  The substituted borine carbonyls may be made by allowing diborane, or a hydrocarbon-substituted diborane, an olefinically unsaturated hydrocarbon and carbon monoxide to react on each other in the absence of water, the introduction of the carbon monoxide being effected under increased pressure.  The olefine and carbon monoxide may be allowed to act simultaneously or consecutively, in either order, on diborane.  Mono-olefines with 2 to 18 carbon atoms, or the corresponding dienes, cycloaliphatic hydrocarbons with 5 to 12 carbon atoms and 1 to 3 double bonds or aralkyl hydrocarbons derived from ethylene by replacement of one or two hydrogen atoms by phenyl or toluyl radicals and possibly alkyl radicals, are suitable reactants. Intermediate products formed by reaction of diborane and the unsaturated hydrocarbon may be separated if desired.  Inert solvents may be used, such as saturated aliphatic hydrocarbons, aromatic hydrocarbons, or ethers, or the unsaturated hydrocarbon itself may also act as solvent.  The carbon monoxide may be used at pressures of 5 to 500 atmospheres.  The reaction of diborane and hydrocarbon proceeds at temperatures of -30 DEG C. to + 100 DEG C., and the subsequent reaction with carbon monoxide, the simultaneous reaction of all three components or the two stage reaction in the opposite sequence, may all be effected at temperatures of 0 DEG C. to 150 DEG C.

Abstract: 599,775. Gas turbines. BRITISH THOMSON-HOUSTON CO., Ltd., and FORSLING, B. E. G. Oct. 22, 1945, No. 27749. [Class 110 (iii)] [Also in Group XXXV] A gas turbine plant comprises high- and lowpressure turbine rotors 10, 13 on independent shafts. The rotor 13 drives an alternator 14 for electric ship propulsion. The rotor 10 drives the air compressor 2 and, through gearing 11, the exciter 12 for the alternator. The compressed air is heated in an economizer 6, preferably as described in Specification 597,852, [Group XIII], and passes to two combustion chambers 8 formed in the lower head of the economizer. For starting, the exciter is used as a motor, air is blown off from an intermediate point in the compressor through a valve 17 and the useful power turbine 13 is byepassed by the open valve 16. When manoeuvring, the load taken by turbine 13 is controlled by the byepass valve 16. In a plant with three turbine rotors on independent shafts, the high-pressure turbine drives the high-pressure compressor and the exciter, the intermediate turbine drives a lowpressure compressor and the low-pressure turbine drives the alternator. The gases are re-heated in a combustion chamber 'between the high and intermediate turbines. For starting, the low-pressure compressor and the useful power turbine are byepassed. In another plant, two low-pressure turbines in parallel receive re-heated gases from the high-pressure turbine which drives the high-pressure compressor and the exciter. One of the lowpressure turbines drives the low-pressure compressor and the other, the alternator. For starting, the low-pressure compressor is byepassed and the inlet valve to the re-heating combustion chamber in front of the useful power turbine is closed or nearly closed.

Title: Improvements in or relating to deflation indicator for pneumatic tyres
IPC: B60C23/06
Filed: 1950-11-21
Abstract: 686,935. Pneumatic tyres. WOOLF, H. H. Nov. 20, 1951 [Nov. 21, 1950], No. 28418/50. Class 144 (i). A device for indicating tyre deflation in running comprises a pivoted feeler rotating with the wheel and resiliently constrained to engage the side-wall of the tyre, the displacement of the feeler on fall of pressure in the tyre being utilized to close a circuit including a fixed contact, a second contact rotating with the wheel, and a visible (or audible) signal. The invention is shown applied to twin wheels 10, 11 bolted to the brake-drum 15 which is fitted with a two-part metal ring 17 carrying, on lugs 19, tubular casings 21 of the rotary contact devices 20. A plunger 24 extending through end-plugs 22, 23 of the casing 21 is urged outwardly by a spring 25 to maintain the feelers 36, 38 in contact with the tyres 13, 12 respectively. The inner end of each plunger is fitted with a nut 28 bearing against a disc 27 on the plunger, a light spring 29 being normally compressed between the disc 27 and plug 23. Rounded heads 30 screwed on the discs 27  form the movable contacts which are arranged to co-operate with diametrically-spaced fixed contacts 45 carried by brackets 48 mounted on the axle-casing 14. The feelers 36, 38 are pivoted on brackets 34, 35 carried by the casings 21. The feeler 36 (for the inner wheel) is engaged directly by the projecting end of the corresponding plunger 24, the plunger 24 associated with the feeler 38 (for the outer wheel) being actuated by an intermediate rocking lever 40. As shown in broken lines in Fig. 4, the flattening of the deflated tyre, at the ground-engaging portion, results in the plunger being forced inwardly to move the nut 28 away from the end disc 27 whereupon the spring 29 reacts to move the head 30 to engage the fixed contact 45 and close the signal-circuit.
