[Also in Division C7] - An organic resin-ceramic composite is made by contacting a ceramic piece with a body of solid metal with sufficient force and relative motion to cause metal to be rubbed on to and bonded to said ceramic piece and then bonding organic resin to the resultant metallized surface of said ceramic piece. The ceramic is preferably a sintered alumina-based ceramic which may contain silica, clay, talc, alkali metal and alkaline earth metal oxides, carbonates or phosphates, or oxides of Cr, Mn, or rare earth elements, but may be a beryllium oxide or zirconium oxide ceramic, and may be in the form of plates, rods, spheres, or random chippings. The coating metal is preferably Ti or Zr, but may be Al, Cu, Fe, Sn, Zn, Mg, brass or steel, and is applied to the ceramic either by tumbling the two together in a rotating barrel, by a rotating wire brush, or by shot-blasting the appropriate metal using the ceramic. The size of the ceramic particles is preferably greater than 100 mesh Tyler, and for coating with Ti or Zr, the surface roughness is less than 10 RMS microinches, but greater than 10 for the other metals. The organic resin is preferably an elastomer such as natural rubber. The resin is vulcanized or cured in contact with the metallized ceramic pieces by conventional means, the volume of ceramic being preferably not more than 20 times the matrix volume. The metal coating on the ceramic is preferably discontinuous, to achieve better ceramic-resin adhesion, and in the barrel coating process, where the metal is Ti or Zr, a nitrogen atmosphere is used to eliminate fire hazards.

Title: Improvements in or relating to flour compositions
IPC: A21D2/16
Filed: 1933-06-13
Abstract: Flour for use in baking is improved by incorporating with it in substantially dry form synthetic fat comprising monoglyceride or diglyceride, or both.  Preferably unsaturated superglycerinated fat is employed, derived from oleic and other acids containing only one double bond, e.g. partially hydrogenated fatty oils such as cottonseed, sesame, peanut, corn, soyabean, whale and pilchard oils, especially oils having an iodine value of 60-70 or lower. Lard and tallow, preferably after slight hydrogenation, may be used as the source of the superglycerinated fat.  The fat is preferably deodorized while still in the form of the triglyceride.  In general, the fats are derived from fatty acids having not less than 16 carbon atoms in the molecule.  Where superior resistance to rancidity is desired the fat may be derived from higher saturated fatty acids like palmitic and stearic acids. The superglycerinated fat may be added to a prepared flour containing shortening and other ingredients such as baking powder or other leavening agent, salt, sugar, dried egg, dried milk and flavouring, and may partially or completely replace the triglyceride shortening therein, usually to the extent of 4-14 per cent.  Examples are given indicating the amount of superglycerinated fats added to prepared flours for making biscuits, cakes, &c.  Free fatty acid, or soap, or a mixture thereof, derived from fat of edible grade may be added to the prepared flours, preferably to the amount of 0,13-4 per cent of the shortening used.  By addition of the superglycerinated fat to prepared cake flours containing chemical leavening agents an average increase in volume of 10-20 per cent with a corresponding increase in lightness is obtained and a higher sugar content, e.g. 125-165 per cent in relation to the flour, may be included.  The superglycerinated fat may be added to the prepared flour by creaming the fat with the dry constituents and then sieving the mixture or by spraying the melted fat on the dry constituents as they are being mixed and then sieving.  Specifications 425,980, 425,981, [both in Group I], and 425,982 are referred to.

Abstract: 545,550. Air &c. compressing. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Nov. 25, 1940, No. 16908. Convention date, Nov. 27, 1939. [Class 8 (i)] [Also in Group XXVII] In an internal-combustion engine, reciprocating compressor, or like apparatus comprising a cylinder or working chamber to which a charge of air, gas, or gas mixture is to be admitted, the charge is increased by providing each cylinder or working chamber with at least one rotation chamber which communicates with the inlet of the cylinder and affords an uninterrupted annular space around the outer wall of the chamber, means to lead air or gas into the chamber in such a manner as to cause its rotation, and one or more outlet openings at or near the outer periphery leading to the cylinder inlet. In a four-stroke engine, Fig. 3, the charge is admitted to the annular rotation chamber 10 by tangential openings 12 in a conduit 11 and is conveyed to an inlet chamber 6 in the cylinder head by a conduit 9 leading tangentially from the periphery of the chamber 10. The effective area of the openings 12 may be varied by means of a sliding sleeve on the conduit. In a modification, the conduit 9 enters the chamber 6 tangentially at its periphery. In a two-stroke engine, Figs. 7 and 9 a charge compressed below the piston, as described in Specification 536,694, [Group XXVII], is transferred through a conduit 19 entering the rotation chamber 21 tangentially, and the inlet valves 22 are located in pockets 25 in a circular wall 23. In another form, Fig. 10, the transfer conduit 19 enters the chamber 21 centrally and is provided with tangential admission slots 26. In further forms, (a) the conduit 19 enters the chamber 21 tangentially and draws in air through a non- return valve and a central tube having tangential slots such as 26 ; (b) a single inlet valve 29, Fig. 14, is arranged below a wall 23 below which are fitted tangential baffles 30 ; (c) the rotation chamber 21, Fig. 16, is substantially conical, the transfer conduit 19 entering tangentially at the narrow upper end of the chamber and the inlet valves 22 being near the periphery of the wide end. The Specification as open to inspection under Sect. 91 states also that the outlet gases from the engine, compressor &c. may be directed into rotation chambers such as those described. This subject-matter does not appear in the Specification as accepted.

Gaseous or liquid fluid supplied through a tube 13 to a chamber 12 issues as lamina flow through a nozzle 14 and discharges to an outlet 24, but energization of a Piezo-electric crystal 19 by an A.C. source 20, resulting in mechanical oscillation of a wall 18, causes the flow to become turbulent and to 'lock-on' to the wall 16 so that the discharge is switched to an outlet 22 until the energization of the crystal is terminated. The crystal may be situated more upstream in relation to the nozzle 14, the walls 16, 29 leading to the outlets may have vents as in Specification 974, 997, and the chamber 12 may be elongated, with thin vanes to act as flow straighteners. Instead of a Piezo-electric element 19 turbulence may be created by a magneto-strictive device; a bi-metal element that protrudes into the fluid path in response to temperature change, or by acoustical vibrations from an oscillating membrane.

Abstract: 971,015. Taximeters. GEECEN Ltd. April 30, 1963 [Oct. 11, 1962], No. 16964/63. Heading G4T. A taximeter comprises a shaft 10 driven by a mixed drive and carrying a two lobe cam 9 for lifting a ratchet arm 2 for indexing a price indicator 6 as the arm returns under the action of a spring 4, and a cam 11 which co-operates with a follower 8 on the arm 2 to prevent the arm from dropping during the initial charge period, during-which time the cam rotates intermittently, then oscillates so that a recess 11<SP>1</SP> in the cam allows alternate drops of the arm 2, and finally stops with the recess 11<SP>1</SP> below the follower 8 allowing every drop of the cam thus doubling the tariff. The cam 11 is rotated against the action of a spring 14 by a pawl 15 reciprocated by an eccentric on the shaft 10, which eccentric co-operates with a ratchet wheel 12 attached to the cam 11,the follower 8 holding by friction the cam 11 while the pawl 15 engages the next tooth. When a pin 16 on the pawl 15 reaches a portion 12<SP>1</SP> of the ratchet wheel, the cam 11 oscillates in unison with the reciprocating pawl 15, so that the recess 11<SP>1</SP> is below the follower 8 at alternate drops. Thus the wheel 6 is indexed once for each revolution of the shaft 10 to provide a first tariff. For each revolution of the shaft 10 an arm 23 is reciprocated longitudinally until the non-return pawl 24 drops in a recess 22 thus engaging a pawl 25<SP>1 </SP>to prevent the return oscillations of the cam 11. Recess 11<SP>1</SP> is thus maintained below the follower 8 from this point on so that every fall of the arm 2 indexes the wheel 6. Thus the wheel 6 is indexed two steps for each rotation of the shaft 10 and the tariff is doubled. Specification 971,014 is referred to.
