Abstract: 1,200,665. Generators operating by electromagnetic interaction with fluids. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 31 May, 1968 [28 June, 1967], No. 29783/67. Heading H2A. [Also in Division C7] A metal electrode, suitable for use in a magneto hydrodynamic generator system in which the hot fluid medium is liable to cause electrolytic or electrothermal attack on the electrode, is provided within the body of the electrode with one or more channels through which cooling water may be passed and at least that part of the electrode which is exposed to the hot fluid medium is composed of zirconium bearing a thin deposited layer of platinum. Typically the platinum layer is of a thickness not greater than 250Á formed by electroplating, e.g. to a thickness of 5Á, and optionally subsequent flame spraying. The zirconium itself may be borne on a core of metal of high thermal conductivity, e.g. copper, as by drawing down a zirconium sheet tube fitted closely over a heavy gauge copper tube.

Title: Improved manufacture of thiourea
Filed: 1932-10-26
Abstract: In the process described in the parent Specification hydrogen sulphide replaces an alkaline earth sulphide an agent being used that gives an insoluble calcium salt such as sulphuric acid, carbonic acid or phosphoric acid.  Sufficient hydrogen sulphide may be added to convert all the calcium into calcium sulphide and all the amide nitrogen into thiourea and the hydrogen sulphide liberated on decomposition used in a further process, or less hydrogen sulphide may be used that formed during the decomposition completing the formation of thiourea.  In examples (1) calcium cyanamide is ground in a ball mill in the presence of water and hydrogen sulphide, sulphuric acid being added to decompose the mass.  The mass is filtered and the filtrate evaporated to crystallize the thiourea. (2) Carbon dioxide is used instead of sulphuric acid as in example (1).  (3) Calcium cyanamide and water are ground in the presence of carbon dioxide and sulphuretted hydrogen.

Patent GB-224102-A (GB)
Title: Improvements in or relating to fuels for internal combustion engines
IPC: C10L1/20
Filed: 1923-12-01
Abstract: Hydrocarbon motor fuels, e.g. kerosene or gasolene, have their critcal compression pressure raised by the addition of a small proportion of an alkyl or aryl compound of lead and of a halide or other chemical which during combustion forms with the lead end-products having less fusing or fluxing action with the metal or porcelain parts of the engine than has lead oxide.  Or a compound of lead, an alkyl or aryl group, and a halogen or other chemical producing the desired end products on combustion may be used. Suitable mixtures are lead tetra-ethyl or methyl or amyl or phenyl with a chlorine bromine or iodine compound, e.g. carbon tetra-chloride, amyl chloride, hexyl chloride, ethyl chloride, benzoyl chloride, chlorinated toluenes, xylenes, cymenes, naphthalenes, oils, ketones, or aldehydes, chloral, chloral alcoholate, chloral hydrate, and dichlorpropane.  Suitable compounds are lead diphenyldibromide or di-iodide or dichloride, lead triethyl chloride or bromide or iodide, and the corresponding ethyl, methyl, phenyl, or other alkyl or aryl compounds of lead and a halogen.  In an example 2 grams of carbon-tetrachloride are mixed with 3 grams of lead tetraethyl or methyl, and 5 cc. of the mixture is added to 1 gallon of gasolene or kerosene. Benzol and an alcohol mixible in all proportions with paraffin hydrocarbons may be added to assist in blending the anti-knock compounds with the fuel.  Specified alcohols are anhydrous ethyl, propyl, butyl, amyl, and other fatty alcohols higher than methyl.

Title: Improvements in or relating to knitting machines
Inventor: HURT FRANCIS NEIL
IPC: D06H3/08
Filed: 1964-07-29
Abstract: A fabric fault detection system for a rotating cylinder type knitting machine comprises a comparison system in which a unit of two photo-transistors is located adjacent the fabric with the photo-transistors in coursewise or walewise spaced positions so that different outputs occur in the presence of a fault, a bi stable circuit responsive to the difference signal, and means to instigate appropriate actio such as stopping the machine.  The fabric is drawn downwardly from a rotating transparent cylinder, and light from a lamp passes through the material and a slit in the unit to the two transducers, one of which is fixed relative to the unit, and the other of which is adjustable as regards its position along the slit by a threaded rod.  The attitude of the unit itself may be adjusted by a second threaded rod.  The difference between the photo-transistor outputs is applied to the bi stable circuit, which may be an Eccles-Jordan, through a level discriminator, and the Eccles-Jordan output is applied to stop the machine, and give a visual, or audible signal by way of a polarised relay.

Title: Improvements in or relating to work feed controls for sewing and other machines

Filed: 1958-01-08
Abstract: 884,857. Automatic control systems. CORDIER, A. Jan. 8, 1958, No. 30913/61. Divided out of 884,856. Class 38 (4). Material which is being automatically advanced is temporarily arrested at one point by a member movable transversely to the direction of movement of the material so that the material makes a rotary movement about the said point. As shown, material 19 lying on the work-table 6 of a sewing machine is advanced perpendicular to the plane of the drawing by a feed dog (not shown) associated with a presser foot 4. The edge of the material is engaged by a spring- loaded feeler 10 operating adjustable electrical contacts 12, 13 relative to a fixed contact 16 so that a solenoid 1 or 2 is energized to cause a pointed member 1b or 2b to engage the material which is then pivoted around the pointed member by the feed to restore the edge to a position which is a predetermined distance from needle 5. Stitching is thus maintained at a fixed distance from the edge of the material. The feeler may serve to arrest the material in place of one of the pointed members. If the curvature of the work is in one direction only, e.g. shoe soles, a single pivoted member suffices.

Abstract: 684,770. Embossing, &c., presses. CROSLAND, Ltd., W., and WILSHAW, F. H. Dec. 4, 1950. [Dec. 2, 1949], No. 30957/49. Class 100 (ii). [Also in Group XXIV] Stopping and tripping arrangements.-In a cutting, creasing and embossing press in which the drive to the machine is through a clutch, normally controlled by a pedal, and which has a rise-and-fall guard which moves the operator's hand when feeding takes place, and also a hand trip rail carrying side guards across the machine in front of the platen so that should the operator's hand remain over the guard it will come into contact with the trip rail and move the latter, thereby disengaging the clutch and applying a brake to stop the machine, the pedal is connected to the clutch through a sliding member formed in two parts normally connected together by a pivoted catch which is operated by the movement of the trip rail to disconnect the two parts and allow the part connected to the clutch to be operated by a spring to disengage the clutch, while any movement of the part connected to the pedal will not operate the clutch. The clutch is actuated by a clutch fork C by means of the reciprocation of a tube D to which is connected a rod D' by a catch d pivoted to a bracket d<SP>1</SP> on the tube, the rod D<SP>1</SP> being reciprocated by the pedal D'. When the pedal is depressed to engage the clutch, a catch e' on a lever e engages a shoulder d' on a socket member D' on the rod D<SP>1</SP> to hold the pedal down until the hand trip rail E is moved to release the catch and allow the clutch to be disengaged, a spring d<SP>4</SP> then moving the rod D<SP>1</SP> to the right. When the rail E is moved with the pedal held depressed, it causes the lever e to abut an arm d<SP>5</SP> of the catch d to disconnect the parts D, D<SP>1</SP>, whereupon the tube D is allowed to disengage the clutch, being moved by a spring coiled on a rod F connected to an arm C<SP>2</SP> of the clutch fork, which spring abuts the machine frame and a sleeve on the rod F to move the latter axially, and, by means of a cone thereon, move a brake into engagement with a wheel on the shaft B which drives the platen.
