Abstract: 611,748. Making screw propellers. REID, J. M., FAIRHURST, L. G., and JACKSON, O. C. April 1, 1946, No. 10082. [Class 83 (ii)] A propeller blade &c. comprising a spar 131 to which leading- and trailing-edge elements 22, 21 are attached, has the element 22 brazed on so that, if damaged, it can be detached by heat. The element 21 may also be brazed on, but this is done with a less fusible material and before brazing on the edge 22. The spar may be made from two stamped halves by welding at 20 after lining with reducing material to reduce flash. Each half may be of channel or L-section 35, Fig. 9, and may have external flanges, not shown, at the joint. The inside may then be shot blasted and the outside machined to size and leave ribs 18. The spar or the halves from which it is made are given the desired twist. The elements 21, 22 are made by bonding over n, former and cutting to size. The edge 21 is first placed on the spar so that its edges engage the rib 18 and is tack welded at 24. Then the assemblage with brazing material, melting at 1,120‹ C., applied is placed in a furnace with the element 21 uppermost. The brazing material collects to form fillets 25. The element 22 is then attached similarly except that the brazing material is fusible at 750‹ C. If desired, less fusible brazing material may be applied at 27, 28 to reinforce the elements 22, 21 before attachment and a strip 29 may be welded or brazed on to the element 21 to form a sharp edge. Alternatively, this element may be formed from two pieces 30, 31, Fig. 10, joined and filled with brazing material 33, 34.

Title: Improvements in or relating to ceramic insulators
IPC: C04B35/46
Filed: 1938-04-04
Abstract: 510,475. Ceramic insulators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 4, 1938, No. 10309. Convention date, April 6, 1937. [Class 22] [Also in Group III] Small ceramic insulators particularly for use as condenser dielectrics, are obtained by sintering to compactness in an oxidizing atmosphere small bodies of titanium dioxide, and cooling the latter, which should be free from lower oxides, in air from at least 1100‹C. sufficiently quickly to obtain products which have a dielectric loss factor of less than 2x10-<3> at a wavelength of 200 metres. Freedom from lower oxides formed during sintering may be ensured either by cooling slowly from the sintering temperature, which may be 1470‹ to 1100‹C., or by maintaining for the necessary time a temperature below the dissociation temperature of titanium dioxide which is yet high enough to enable reformation of the dioxide to occur fairly rapidly. The bodies of titanium dioxide, which may be plates or tubes, may be obtained by mixing sintered and ground oxide with an organic binder such as tragacanth and distilled water, moulding and drying. Sintering of the bodies so formed is preferably effected either in gas heated muffles, the air content of which may be replenished or in an electrically heated tube furnace. Examples of operation are given.

Title: Improvements in heaters for the intake manifolds of internal combustion engines
IPC: F02M31/083
Filed: 1933-04-06
Abstract: 417,522. Heating charge. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. April 6, 1933, No. 10317. Convention date, April 7, 1932. [Class 7 (iii).] An exhaust-heated device for the inlet manifold is controlled automatically, according to the engine speed and temperature, by a flap valve 18 which causes the exhaust from the manifold 12 to flow directly to the exhaust pipe 14, or to be byepassed into a jacket 22 surrounding the inlet manifolds 25, before flowing by a conduit 16 to the exhaust pipe. The valve 18 is controlled automatically by a bi-metallic spring 35 which, when the engine is cold, turns the valve 18, against the action of a weighted arm 34, into the position shown in full lines, thereby byepassing all the exhaust gases. As the engine warms up, the torque exerted by the thermostat 35 decreases, allowing some of the exhaust to flow directly into the pipe 14. The pressure of the exhaust gases also tends to move the valve 18 from the full-line position, in proportion to the speed of the engine. The inlet manifold 25, which as shown is of the double-barrelled type coming from a downdraught carburetter, is fitted with copper sections 24 within the jacket 22, and with copper domes 29 below the horizontal extensions 28 of the manifolds. The valve 18 is shaped to give an easy flow to the exhaust gases.

Filed: 1974-03-12
Abstract: 1420552 Measuring displacements electrically INTERNATIONAL-BUSINESS MACHINES CORP 12 March 1974 [21 March 1973] 10865/74 Heading G1N The invention relates to the writing telegraph system of Specification 1269787 comprising a tablet represented by resistance 20, Fig. 8 to one end of which is supplied a voltage V 1  sin wt, the other end being connected in cyclic alternation to the supply voltage and to earth, for equal periods T determined by a flip-flop 19 controlled by a clockpulse generator 11. Thus the voltage V 1N  fed to a detector 31 from the pen 24 via coupling capacitor 29 is a reference high voltage whose amplitude is that of the supply voltage V 1  sin wt, followed by a low voltage whose amplitude represents the fraction of the supply voltage tapped off by the pen. These voltages are rectified and integrated at 33. The rectified low voltage is integrated for the period T: the rectified high voltage is inverted before integration and the time for the second integral to equal the first integral is measured by the clockpulses from generator 11  and registered at 21 as representing the distance of the pen from the lower end of the writing tablet. In the present invention the resistance 20 is divided into a plurality of sections by tappings ALO, AHI, BLO, BHI, &c. which overlap, e.g. as shown by BLO-AHI. The time constant of the integrator 33 is modified for the high voltage periods by adjusting resistor 26 so that each section of resistor 20 effectively extends between the said points of the overlap. When the pen 24 is placed on the writing tablet, the control logic 100 initiates measurement for the first section ALO-AHI. If the pen is not associated with this section the control logic 100 switches the supply voltage from the first to the second section and so on, while the system stores information relating to the number of tested sections, until the pen is located and its position measured.
