Title: Duo-servo brake with adjusting means
IPC: F16D65/56
Filed: 1974-03-06
Abstract: 1459872 Wear adjusters DEUTSCHE PERROT-BREMSE GmbH 6 March 1974 [7 March 1973] 10134/74 Heading F2E Axial movement of a duo-servo brake anchor pin abutting ends of brake shoes in one direction from a centre position, caused by shoe movement upon brake actuation, causes a lever 19, mounted on a brake support 1, to pivot about one of two possible axes both perpendicular to a plane containing the pin axis; two pawls 29, 31 of the lever are moved circumferentially of associated ratchet wheels 17 at each end region of the pin so that if shoe movement is sufficiently great, one of the pawls moves a wheel tooth distance to index the wheel upon lever return, causing the anchor pin to lengthen, whereas the other pawl does not move a sufficient amount for this to occur with the other wheel; upon opposite pin movement of a sufficient amount upon brake actuation pivoting of the lever about the other axis causes the other pawl only to index its wheel upon return. The anchor pin comprises two bolts 3 non-rotatably held, by respective brake shoes, in respective sleeves 5 in a common sleeve 7 axially slidable in the stationary brake support, e.g. a U-bracket 1. The lever, e.g. a plate 19 is supported by pins 21, 23 in elongate curved slots 25, 27 and mounted in the bracket 1, and has resilient tongue pawls 29, 31 for engagement with the respective ratchet wheels 17 mounted at the outer ends of the sleeves 5 with optional spacers 11. Upon axial bolt movement, caused by shoe movement, say rightwardly, although leftward movement can occur, after a small clearance is taken up, the left hand wheel 17 abuts a projection 33 of the plate 19 to pivot it about the pin 21 causing a circumferential movement of the pawl 31 which moves across a wheel tooth if the shoe movement is great enough. Upon return, a spring 39 pulls the pawl 31 to move the wheel 17 to rotate the righthand sleeve 5 to extend the bolt 3. Movement of the pawl 29 in this instance is never great enough to engage a new tooth on the lefthand wheel 17. Surfaces of the bracket 1 avoid over travel of the pawls 29, 31 for new tooth engagement. Fig. 4 shows an axially slidable sleeve 47 having pins 49 effecting plate rotation rather than the projections 33, 35 thereof.

Abstract: 821,674. Electric measuring systems. BRITISH THOMSON-HOUSTON CO. Ltd. April 2, 1958 [April 2, 1957], No. 10750/57. Drawings to Specification. Class 40 (1). An indication of the effectiveness of a cooling system is obtained by placing two thermistors in heat transfer relationship with the flow of cooling medium, the thermistors being connected in two arms of a bridge circuit which is arranged to supply a predetermined output, preferably zero, when the cooling operation is normal. As described, one thermistor is placed in contact with the wall of a section of a pipe in the cooling circuit at a point beyond the cooled object, such section being insulated from the rest of the pipe, as by gaskets of heat-insulating material, or by making the rest of the pipe of insulating material, and the second thermistor is in contact with the reservoir containing the cooling medium. Alternatively, both thermistors may be positioned close to, but insulated from, one another, the thermistors having different thermal time constants, or the pipe sections in which they are located having different thermal capacities, so that, on a change of temperature of the cooling medium, the temperature of one thermistor will alter more quickly than the temperature of the other.

Title: Process for the production of finely divided metal powders by thermal decomposition of metal carbonyls
IPC: B22F9/30
Filed: 1958-04-03
Abstract: Finely divided metallic powders of a uniform particle size are prepared by mixing one or more gaseous carbonyls with an inert gas such as nitrogen which is heated to above the decomposition temperature of the carbonyls.  Cold inert gas may be mixed with the carbonyl vapour before the reaction and the product metal may be cooled immediately it is formed by cooled surfaces, water injection or by mixing with cold inert gases.  The pyrophoric nature of the powdered metal may be decreased by mixing with the inert gas oxygen (preferably 0.001% by volume) or carbon dioxide, the final product being obtained by treatment under vacuum to remove the protective layer from the particles.  The process is particularly applicable to the production of iron and nickel powders and reaction temperatures of between 180 DEG C. and 450 DEG C. are preferable with the walls of the reaction vessel maintained 5 DEG C. below the reaction temperature.  For ultra-fine powders, the concentration of carbonyl in the reaction gas is kept below 1 mol per cent.  Specification 832,317 is referred to.

Abstract: 459,710. Pneumatic conveyers. HURLEY, T. F., and DICKINSON, R., Fuel Research Station, Blackwall Lane, East Greenwich, London. April 9, 1935, No. 10922. [Class 78 (i)] [See also Groups II and XI] A plurality of streams of fluent material are mixed in an apparatus comprising an arrangement of ducts by means of which the original streams are first divided into intermediate streams flowing in intermediate ducts, which streams are then subdivided into terminal streams flowing through terminal ducts which are arranged in rows in such a manner that each intermediate duct communicates with regularly spaced ducts in one row and with regularly spaced ducts in an adjacent row which are in staggered relationship with the ducts of the first row. The apparatus comprises two or more branches 9 and 10 leading to a unitary structure 1. Branch 9 is divided into intermediate ducts 8, 8b, 8d, 8f, Fig. 7, and branch 10 into intermediate ducts 8a, 8c, 8e, 8g. The ends of the intermediate ducts from branch 9 are arranged alternately with those from branch 10, i.e. in the order 8. 8a, 8b, to 8g, Fig. 1. From the intermediate ducts the material flows into the unitary structure 1 composed of terminal ducts arranged in rows, an end view being shown in Fig. 3. Intermediate duct 8a communicates with terminal ducts 6 in one row and 5a in an adjacent row; intermediate duct 8b communicates with terminal ducts 6a and 5b, &c. To allow of this arrangement, alternate rows, 6 to 6f, 5 to 5f, of terminal ducts are inclined in opposite directions, preferably to the extent of half the width of a duct as indicated in Fig. 4. The area or the form of the cross-section of the duct may be modified so as to promote a constant velocity of flow of material through successive ducts and the form of the ducts or of certain of them may be modified so as to secure a Venturi effect. The apparatus may be used in the reverse direction to divide a stream of fluent material.

Title: Improvements in and relating to the reinforcement of rigid or flexible moulded bodies
Inventor: AMBROS OTTO
IPC: C08J5/04
Filed: 1956-04-12
Abstract: Ethylene or propylene is polymerized with the aid of a catalyst consisting of a metal alkyl and, if desired, a titanium halide dissolved in a solvent to which a filler may be added, e.g. by producing it in the solvent before commencement of the polymerization, as by decomposing silicon halide in a hydrocarbon solvent to form silicon hydroxide, by the use of small quantities of substances with free OH groups.  Alternatively, substances may be suspended or dissolved in the solvents to bind traces of water or acids already present, or formed during the polymerization reaction, e.g. gamma aluminium oxide, active silica gel, anhydrite, or a glycol.  Polythene prepared by treating ethylene with a metal alkyl in a low-boiling hydrocarbon mixture may be melted and drawn into filaments which may be stretched to 12 times their original length. In examples: (1) ethylene is led at slightly raised temperature and ordinary pressure into a suspension of asbestos or cotton fibres or cork powder in a low-boiling hydrocarbon mixture to which a metal alkyl is added; the individual fibres are enveloped by the polymer; (2) finely-divided silica, obtained by burning silicon tetrachloride, is suspended in a low-boiling hydrocarbon mixture, and the suspension is mixed with a solution of a metal alkyl in the same hydrocarbon mixture; ethylene is fed into the suspension while stirring vigorously; the polyethylene formed separates off on the fine silicic acid particles; (3) calcined aluminium oxide, diethyl aluminium monochloride, and titanium tetrachloride are added to isopropylcyclohexane and stirred under nitrogen in the cold; ethylene is introduced and the temperature raised to 80 DEG  C., white fibres are obtained by extrusion; (4) as in (3), but using calcined titanium dioxide instead of calcined aluminium oxide; (5) aluminium oxide, titanium tetrachloride, and aluminium triethyl are added with stirring to isopropylcyclohexane, and propylene is pumped in at 60 DEG  C.; after washing with propanol and vacuum drying, white threads are obtained by extrusion.
