Filed: 1947-08-28
Abstract: 636,143. Imitation fuel. BELLING & CO. Ltd., and EASTWOOD, M. Aug. 28, 1947, No. 23832. [Class 126] Imitation fuel for an electric fire is formed from a wire framework or foundation to which are attached pieces of open mesh wire net on which is keyed after attachment a setting plastic representing log fuel. The framework a having portions b bent up to support areas in which log formations are to be represented is wound loosely with tow or twine g. Wire net c is arranged over the framework a in the approximate shape of the final log formation. The wire net c is covered with a suitable material which sets on baking, e.g. paper pulp or sawdust bound with gelatine and treated with formaldehyde, this material being moulded to the required final shape and texture. Appropriate colour is then applied. A flicker device together with reflectors (not shown) may be incorporated within the imitation fire, in which case vents f are formed by the absence of the covering plastic.

Abstract: A priming paint is made by incorporating a urea-aldehyde resin and diacetone alcohol in a priming paint comprising an alkyd resin or an alkylphenol-aldehyde resin and a solvent therefor, the urea-aldehyde resin constituting a minor proportion of the total resin content.  In examples, the paint consists of (I) 100 parts (by weight) glycerol-phthalate resin, 10 to 50 parts urea-formaldehyde resin, 90 parts ethyl and methyl acetates, 30 parts diacetone alcohol, 10 parts toluol, and 200 parts zinc oxide, and (II) 100 parts alkylphenol-formaldehyde resin/wood oil varnish, 10 parts urea-formaldehyde resin, 15 parts ethyl acetate, 5 parts diacetone alcohol, 5 parts toluol and 80 parts red lead. The paints give coatings which, when dry, are unaffected by solvents of finishing paints.  German Specification 666,663, which discloses the use of solid oxidation products of drying oils, e.g. linoxyn and gelatinized wood oil, in organic solvents as binding agents for bitumen and benzene-resisting ferrous priming paints, is referred to.

Title: A method of feeding strands of fibrous material to the drafting heads of textile spinning machines or to the spindles of twisting machines
IPC: B65H49/24
Filed: 1950-10-05
Abstract: 729,203. Feeding roving, yarns, &c., to spinning &c. machines. SCHIESS AKT.-GES. Oct. 5, 1950 [Oct. 29, 1949], No. 24297/50. Class 120(2). The retaining rollers of a drafting head or the delivery rollers of a twisting machine are replaced by a supply unit comprising a package of roving or yarn and a supporting roller or rollers. In one form of drafting head, Fig. 2, a package 1 is disposed on a feed roller 5a and loads by its own weight the roving 3 to retard it whilst it is drawn by the rollers 11; 12. According to the inclination of a package support 15, the frictional force affecting retardation is affected. Instead of a single supporting roller, two rollers may be employed, the distance between the axes of which may be varied to alter the frictional force they exert. One or both of these rollers may be fluted, or covered with material having a high coefficient of friction or a belt having a roughened, fluted or grooved surface may extend between the rollers. The bobbin carrying the package may be heavy or a metal weighting pin may be placed in a tubular bobbin. If desired, bobbins may be mounted in pairs on single shafts and either singly or in pairs they may be supported on three or four lines of rollers in staggered or other relationship. Material may be wound onto the packages with a pitch that decreases towards the middle of the length of the package. In a twisting frame, Fig. 18, the package 1 rests on a driving roller 58 and the strand 3 is fed substantially vertically to the twisting spindle.

Title: Improvements in or relating to automatic emergency electric generating plants
Inventor: ALCOCK JOHN FORSTER
IPC: H02J9/08
Filed: 1952-10-06
Abstract: 721,933. Stand-by power supply plant; synchronizing. RICARDO & CO., ENGINEERS (1927), Ltd. Oct. 1, 1953 [Oct. 6, 1952; Jan. 22, 1953; Sept. 16, 1953], Nos. 25001/52, 17278/55 and 25657/53. Class 38 (4). In a stand-by power-supply system of the kind wherein an internal-combustion engine A is automatically started upon failure of the main supply and drives as a generator a synchronous machine B<SP>1</SP>, previously motoring on the mains and coupled to a flywheel E<SP>1</SP> which supplies driving power for the machine whilst the engine is starting, the operation of synchronizing the machine B<SP>1</SP> with the mains is facilitated by the provision of a clutch E<SP>2</SP> between the machine and the flywheel in addition to the usual clutch C between the machine and engine. By this means the machine may be run up by the engine (started by a motor A<SP>1</SP>) synchronized and switched on to the mains D free from the inertial load of the flywheel which may be subsequently clutched to the machine when the flywheel is running at synchronous speed. The engine is then declutched and stopped. Subsequent mains failure causes devices C<SP>2</SP>, C<SP>3</SP> to respond, thereby engaging the clutch C to start the engine by the momentum of flywheel and machine, which thereafter is driven by the engine until mains restoration. For bringing the flywheel up to speed, it may initially be clutched to the machine B<SP>1</SP> and run up therewith to a speed slightly in excess of synchronous speed, then declutched, and subsequently reclutched after the machine has been synchronized and connected to the mains. Alternatively, a slipping clutch may be employed to allow the flywheel to be accelerated from rest by the machine after it has been synchronized. Instead of using the engine A, the machine B<SP>1</SP> and flywheel may be run up by an auxiliary electric motor; or the machine B<SP>1</SP> may be adapted for starting as a non-synchronous motor. In other arrangements the machine B<SP>1</SP> normally motors, with the flywheel unclutched but maintained in rotation at a speed slightly in excess of synchronous speed by an electric motor energized from the mains. Mains failure causes the flywheel to be clutched to the machine B<SP>1</SP>. To maintain the engine warm, in readiness for a quick start on mains failure, it may be provided with a jacket into which the exhaust cooling air of machine B<SP>1</SP> is discharged after passage past the flywheel, which is also jacketed and acts as a crude centrifugal fan further warming the exhaust air. Specification 320,624, [Class 38 (iv)], is referred to.
