Title: Improvements in and relating to heating devices for wind screens and the like
IPC: H05B3/84
Filed: 1933-04-22
Abstract: 422,953. Preventing dimming of vehicle windows. MARCELAIS, J. O., 156, Millicent Avenue, Buffalo, New York, U.S.A. April 22, 1933, No. 36369 /32. [Class 20 (iii)] The accumulation of snow, ice, and moisture, on windscreens and windows is prevented by an electric heating device carried by a glazed frame which rests against the windscreen or window and is movable longitudinally relatively thereto. In the form shown, the glazed frame 1, Fig. 1, is carried by arms 4 which are slidably mounted on a rotatable rod 2 mounted in end brackets 3. The frame rotates with the rod and a coil spring within one or both of the brackets tends to keep the frame in close contact with the windscreen. A releasable ratchet device also mounted in each bracket holds the frame in any angular position of adjustment. As shown in cross section in Fig. 4, the frame 1 is of angle section and carries a glass pane 9 which is embedded in a strip 10 of cork or rubber. This strip is secured to the frame by a plate 12 which also serves to clamp to the frame a second resilient strip 13 which abuts against the windscreen. Along the lower edge of the frame are arranged two parallel resistance heaters 18, 19, separated by a porcelain insulator 21 and covered by a perforated guard 20. Current is supplied to the heaters by a wire 29 passing through a socket block 28 which is provided with means for supplying current either to one or both of the heaters. Air is admitted to the space between the frame and windscreen by openings along the lower edge of the frame, valves 30 being provided to regulate the quantity of air admitted. The air is allowed to escape by separating the upper edge of the frame from the windscreen by means of a rotatable cam 35. Resilient pads 26 are secured to the frame and serve to wipe the windscreen when the frame is moved longitudinally. An anti-glare shield 25 is pivoted to the frame, the pivots being spring-pressed so that the shield may lie over the glass 9 or upwardly out of the way.

IPC: B29C48/05
Filed: 1970-07-28
Abstract: 1,262,020. Filled fibres. NYPEL Inc. 28 July, 1970, No. 36582/70. Heading B5B. Bristles having a filler, such as an abrasive filler, are produced by heating a thermoplastic material to above its melting point in a screw extruder 12, feeding the melt to a second screw extruder 26, where it is mixed with the filler and then feeding the mixture to an extrusion die 42 where it is formed into a plurality of monofilaments. The monofilaments are passed through a bath 46 where they are cooled and solidified and are then formed into a ribbon 52 as herein defined. This ribbon is stretched over a first set of godet rolls 54 which have a replaceable, wear-resistant lining 53, and is then treated with hot water, dried and stretched again over a second set of rolls 66, protected as is the first set, and then crimped and the filaments cut into individual bristles.  The filler may be present to between 1 and 50% of the material leaving the second extruder and, if abrasive, is preferably between 36 and 1000 mesh. Suitable fillers are, for example, aluminium oxide, chopped glass fibres, asbestos, diamond or ceramic particles. The wear resistant lining for the stretching godet rolls may be any suitable metal or non- metal, but copper is preferred. In an example, bristles are prepared from a mixture of nylon 6 and nylon 6,6, having aluminium oxide filling.

Title: Improvements relating to automatic steering systems for dirigible craft
IPC: G05D1/02
Filed: 1937-06-22
Abstract: 501,512. Automatic control systems. SPERRY GYROSCOPE CO., Ltd., SAUL, G. C., HARDING, W. G., and NISBET, R. H. June 22, 1937, No. 36628/38. Divided out of 499,644. [Class 38 (iv)] Steering.-In order to damp the oscillations of a ship or other dirigible craft when automatically steered, the rudder controller movement, imparted by compass and increasing with increasing movement thereof, is supplemented by a further compass-actuated movement changing in direction with change in direction of compass movement, this additional controller movement being limited by stops. Thus, when the ship begins to swing back to her course an initial reduction of rudder is obtained. Provision may be made for this initial rudder to be progressively reduced to nothing as the ship reaches her course. A compass repeater motor 15 may actuate a controller arm 110<1>, Fig. 1, through a differential gear, the casing 50 of which is restrained by an adjustable stop 58. A gear-wheel 52 is frictionally driven bv the motor-actuated shaft 16<11> so that the differential casing, to which this gear is coupled as shown, is driven against one side of the stop until the compass motion reverses, whereupon the casing 50 moves over against the other side of the stop and effects the required initial rudder movement of the arm 110<1>. Fig. 3 shows a friction driven sector 77 adapted to apply the initial rudder movement to the " fixed " contacts of the controller instead of to the controller arm. Fig. 2 shows a friction-driven pinion 52<1> and rack bar 60 adapted to give the additional movement to the differential casing 50. A dashpot 67 permits a pair of spring-actuated arms 71, 72 to centralize this casing at a rate determined by a valve 76 and so provide a progressive reduction to zero of the initial rudder adjustment. In a further modification, a friction driven switch arm on the compass actuated spindle of the controller selectively energizes two electromagnets operating through a similar dashpot and centralizing means on the differential casing.

Abstract: 1,143,265. Control of A.C. motors. INDUSTRIAL INSTRUMENTS Ltd., and LAURENCE, SCOTT & ELECTROMOTORS Ltd. 27 Sept., 1967 [17 Aug., 1966], No. 36894/66. Heading H2J. An induction motor is supplied through an inverter whose output frequency is controlled in response to a D.C. reference signal which is over-ridden to increase the frequency when the motor tends to regenerate. An oscillator 11 controls the frequency of firing pulses applied to thyristors included in the inverter, the oscillator being regulated normally by a reference voltage derived from a potentiometer VR. When the motor regenerates, transistor TRI is switched off and an over-riding H.T. signal is applied to the oscillator through diode D1, diode D2 being blocked. The increased voltage is applied to the oscillator to increase its output frequency until the motor ceases to regenerate and the inhibiting signal is removed from the base of the transistor TRI. A further over-ride signal is obtained during the starting operation of the motor, a switch SI being opened, whereby capacitor C2 is charged through resistors R2, R4. The voltage applied to the oscillator increases until diode D3 is reversed biased and the potentiometer VR takes over the control.

Abstract: The composition of a nickel-based alloy powder suitable for hydrostatic compression to form turbine blades is in the following proportions by weight:-Chromium 20%, Cobalt 16%, Titanium 2,35%, Aluminium 1,35%, Carbon 0,07-0,1%, Boron 0,05%, and the balance of Nickel.  The alloy is produced from the following powders:-Carbonyl nickel powder Chromium-cobalt master alloy 55,5% Cr, 45,5% Co, Chromium-cobalt-titanium master alloy 44,4% Cr, 35,6% Co, 20,0% Ti, Chromium-cobalt-aluminium master alloy 44,4% Cr, 35,6% Co, 20,0% Al. Chromium-cobalt-carbon master alloy 51,0% Cr, 41,0% Co, 8,0% C, Cobalt-boron master alloy 96% Co, 4% B. Cadmium core wires are located in the moulding composition which is compressed in a rubber bag immersed in pressurised glycerine. The compact is then heated to 650 DEG C., the temperature being raised at the rate of about 160 DEG C. to remove the cadmium.  The compact is finally sintered by heating at 1300-1325 DEG C. for 20 hours in vacuum.  Specification 611,466 is referred to.ALSO:Ducts, holes, or voids are produced in an article such as a turbine blade by inserting at least one former into a mass of powdered material, e.g. metal, metal oxide or carbide, or refractory material, subjecting the assembly to hydrostatic pressure to produce a compact, and subjecting the compact to heat treatment so that the former is completely or substantially completely removed by volatilisation or is dispensed into the compact which is then sintered.  In one example, a loose compact containing cadmium wires was produced in a die from a nickel based alloy powder and the loose compact was placed in a rubber bag which was immersed in glycerine and subjected to hydrostatic pressure.  The resultant pressing and the cadmium wires were then heated to 650 DEG C to remove the cadmium and the ducted pressing was then sintered at 1300 DEG C.  The preliminary compacting step may be dispensed with and alternative materials for the formers are tin, aluminium, zinc, indium, polystyrene, and wax.  Specification 611,466 is referred to.

Title: Improvements in the production of acid-free esters
IPC: C07D213/803
Filed: 1954-12-24
Abstract: Acid-free esters are produced from alcohols and high-melting dicarboxylic acids which are insoluble or very difficulty soluble therein in the presence of an esterification catalyst by suspending the dicarboxylic acid in a mixture of excess of an alcohol and an esterification catalyst, heating to a temperature of at least 60 DEG C., but below the melting-point of the dicarboxylic acid, withdrawing and separating from unesterified acid the resultant ester as formed as an alcoholic solution containing water and esterification catalyst while replacing the withdrawn alcohol and catalyst by fresh alcohol and catalyst, and if necessary, isolating the ester from the said alcoholic solution.  It is preferred to use lower alkyl alcohols such as methyl, ethyl or propyl alcohol.  Suitable high-melting dicarboxylic acids are isophthalic, terephthalic and isocinchomeric acids.  Hydrogen chloride, and boron trifluoride are the preferred catalysts since they are volatile but generally all esterification catalyst which are soluble in the alcohol used are suitable.  It is advantageous to carry out the process continuously in an extraction apparatus in which the high melting dicarboxylic acid is situated and through which the alcohol containing catalyst slowly flows at a speed at which the ester can form during its passage through the apparatus. The ester may be separated from the alcoholic solution by cooling and crystallization, and the mother liquor, after removal of the water and, if necessary, after replenishment of the catalyst, can be used for further esterification.  In some cases the solution may be worked up by distillation after removal of the water and catalyst present to prevent saponification of the ester.  In an example, a cylindrical vessel provided with a steam jacket, a lid, and a bottom outlet, and containing an extraction thimble of close glass fabric in which a stirrer rotates, is kept full of methanol by means of a levelling tube; terephthalic acid is charged into the extraction thimble and the whole is heated to 60 DEG  C. while at the same time dry hydrogen chloride is introduced; after 3 hours a continuous flow of methanol is also introduced from a measuring vessel and the alcoholic solution of ester flowing from the bottom outlet is cooled in a cylindrical vessel whereby dimethyl terephthalate crystallizes out; the product is filtered off and the mother liquor concentrated to obtain further product and then the methanol is dehydrated and fed back to the extraction vessel.
