IPC: B26F3/06
Filed: 1947-03-22
Abstract: 658,244. Moulding thermoplastic sheet material. CHARRON, C. S., and BROWN, L. CRAWFORD-. March 22, 1947, No. 7923. Convention date, Dec. 5, 1946. [Class 87 (ii)] [Also in Groups VIII and XVI] A flexible or rigid sheet of thermoplastic material is bonded to thermoplastic material or to other material, such as fabric, by subjecting the materials to heat and pressure. The materials may be simultaneously cut and/or embossed. The pressure may be applied over the whole of or at spaced points of the surface of the material. A press for effecting the bonding comprises a stationary platen 12, on which superposed plies of material are placed, and a movable platen 15 having a die 17 which is heated by electric elements 18, controlled by a thermostat 19. The platen 15 is mounted on a shaft 14 which slides freely in a part 13 of the press frame. The lower limit to which the platen can move, when pressure is applied, is adjusted by nuts 21 on the screwed end of the shaft 14. The platen 15 is normally held in retracted position by springs 22. Pressure is applied by a foot lever 23, which, on depression, lifts a tube 25, compressing a spring 32 mounted on a rod 26, telescoping in the tube 25. Upward movement of the rod 26 due to the action of the spring, causes downward movement of the platen through a lever 28. The pressure is controlled by adjusting the position of nuts 31 against which the spring 32 abuts. In a modification, Fig. 2 (not shown), fluid pressure may be used, to move the platen, the pressure being controlled by a valve. A light 37 is provided to indicate to the operator the required duration of the pressing stroke. The light is controlled by a clockwork mechanism operated by a finger 36, adjustably mounted on the tube 25. Sheet material, e.g. " Cellophane " (Registered Trade Mark), may be placed between the heated die and the material to prevent it sticking to the die. It may be left on the material until cool, to prevent the material crinkling.

Title: Improvements in or relating to guided wave transmission systems
IPC: H01P1/02
Filed: 1963-02-28
Abstract: 1,031,525. Waveguide bends. WESTERN ELECTRIC CO. Inc. Feb. 28, 1963 [March 8, 1962], No. 8010/63. Heading H1W. Unwanted, higher order modes generated at a reflecting bend are suppressed by delaying one portion of the wave incident upon the reflecting surface with respect to other portions. The invention may be applied to the elimination of TE 02  mode energy appearing at a bend in a circular waveguide 11, 12 intended for transmission of energy in the TE 01  circular electric mode. A reflective surface 14, Fig. 1, perpendicular to the bisector of the angle 0 between the waveguides 11, 12 is provided with an annular groove which delays part of the reflected wave. At a given frequency it is possible to eliminate TE 02  mode conversion by choosing the dimensions of the annulus such that the sum of the scattering coefficients of the two reflected portions for the TE 02  mode is zero. Suppression over a band of frequencies may be obtained by using two compensated bends spaced apart by a distance #b/2 where #b is the TE 01 -TE 02  beating frequency at some frequency spaced from the first compensating frequency. In a modification, the discontinuity in the reflecting surface 14, Fig. 3, is produced by means of two concentric recesses closed by adjustable screws 20, 21. The recesses shown in Figs. 1 and 3 may be replaced, respectively, by a dielectric annulus and by two concentric dielectric cylinders (Figs. 9, 10, not shown). Segmental recesses spaced diametrically opposite to each other in the plane of the guide axes may be used instead of a complete annular recess. The whole of the reflecting surface may be in the form of a curved concavity symmetrical about the bisector of the bend.

Title: Improvements in the polymerisation of propylene
Inventor: HOEG DONALD F
IPC: C08F110/00
Filed: 1962-03-30
Abstract: High molecular weight polypropylene is produced using a catalyst comprising a trialkyl aluminium compound in which the alkyl group contains 1 to 8 carbon atoms and titanium di- or tri-chloride having propylene absorbed thereon. The polymerization is carried out at a temperature of 50 to 200 DEG C. and a propylene pressure of 2 to 70 atmospheres.  The catalyst is formed by grinding the titanium chloride at room temperature in a propylene atmosphere, preferably at superatmospheric pressure e.g. up to 10 atmospheres until the titanium chloride has absorbed, for example, at least 0.5% of its weight of propylene, and then mixing this ground chloride with the trialkyl aluminium compound.  In general the amount of catalyst used is 0.05 to 0.003 grams of total catalyst per gram of propylene to be polymerized.  The weight ratio of the titanium chloride with propylene absorbed thereon to the trialkyl aluminium compound may be in the range 5:1 to 1:10.  Where the polymerization is performed at a temperature at which the polymer remains in solution, the metallic catalyst can be removed by filtration, if desired after adding a chelating agent.  In the examples the trialkyl aluminium compound used is triisobutyl aluminium.
