A switch S6 when closed and opened again enables, since it is connected to the signal E o  the time constant G, R6 being smaller than that of the integrator, the potential E R  to change rapidly to E M  ensuring that the pre-set rate change of the signal E R  starts from the value E M . Switch S 5  enables E R  to be rapidly set if desired to the value E D  in view of the small time constant C 1 , R 5 . The signals E D , E M  may be connected to the system via buffer amplifiers comprising differential amplifiers connected in a summing mode. The polarity of the signal E o  determines which one of the coils of relay H is energized, and hence controls heating, or cooling respectively in the process, or for closer control, the analogue signal Ec, having in view of the feedback R7, C2 of amplifier A4, a proportional + integral characteristic, is used. Further amplifiers (not shown) receiving signals Eg , E M  , may indicate whether E R  # E M , or E R  =E M . The signal E D  may be derived from a potentiometer. In the arrangement of Fig. 1 (not shown), a ramp generator (R) provides an increasing, or decreasing ramp signal (E R ), in dependence on the polarity of the output (E A ) of the amplifier (A 1 ).

Title: Improvements in Methods and Apparatus for Manufacturing Composite Materials Reinforced by Trichites
IPC: C22C47/00
Filed: 1967-10-16
Abstract: 1,198,824. Coating with metals; electrolytic deposition. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. Oct. 16, 1967 [Oct.14, 1966], No.47089/67. Headings C7B, C7F. [Also in Division B3] A method of making a composite material consisting of a metallic matrix reinforced by ceramic trichites includes the steps of sheathing the trichites with a metallic film, orientating and depositing the trichites on a temporary support, forming a thin elementary sheet by electrolytic deposition of metal on the trichites on the temporary support, subjecting the deposit to thermal treatment and producing a sheet of a given thickness by the superposition of a plurality of the elementary sheets. The trichites e. g. of alumina, are sheathed with a metallic film by clamping a felt 35, Fig. 2 of the trichites between two plates 36, 37, placing the felt over an opening 34 between two chambers 20, 21, heating the felt by heaters 38 and passing a mixture of a metallic halogenide e. g. molybdenum pentachloride, and a reducing gas e.g. hydrogen, under pressure into the chamber 21. The MOCl 5  is reduced by the hydrogen in the region where the temperature is sufficient i.e. in contact with the felt 35. The trichites are then oriented and deposited on a temporary support by a carding device, Fig. 3. A metal sheet 42 is mounted on a drum 41 which is rotated at high speed and the sheet 42 is coated with adhesive 43 by a roller 44. The trichite felt 45 is pressed against the drum 41 by a piston 46 which causes the trichites to become orientated and deposited on the sheet 42. The adhesive e. g. a non-polymerized resin, is then eliminated by distillation in vacuo. The metal sheet 42 supporting the trichites is removed from the drum 41 and is used as the cathode in an electrolytic deposit bath where the metallic matrix e. g. nickel is deposited on the trichites. The sheet thus formed is removed from the support 42 and is then heated in vacuo at a suitable temperature e.g. 700‹ C. in the case of nickel to improve the adherence between the matrix and the trichites. Composite sheets are then formed by superimposing a plurality of the sheets and subjecting the sheets to a hot compression followed by a thermal diffusion treatment. The composite material may be used for the manufacture of members subjected to mechanical stresses produced by rotation at high speed e. g. turbine vanes or helicopter blades.

Title: Processes for the preparation of terephthalic acid and the preparation of linear polyesters therefrom
Inventor: UNO SEIJI
IPC: B01J2/22
Filed: 1963-12-03
Abstract: A process for the preparation of terephthalic acid for production of polyesters by direct esterification comprises compressing terephthalic acid or a mixture of terephthalic acid with other organic bifunctional acid or acids, e.g. adipic, sebacic, isophthalic, bibenzoic acids, or aromatic oxycarboxylic acids and thereafter optionally crushing the same, to make the bulk density thereof at least 0.8 and the average particle diameter thereof not more than 8 millimetres.  Esters may be prepared from the acids so produced by reacting the same with a glycol to form bis-(hydroxyalkyl)-terephthalate or a low molecular weight polymer thereof, and then polymerizing the result of the reaction product by heating under a reduced pressure. In an example to a slurry of monopotassium terephthalate with water heated to 90 DEG  C. phthalic anhydride was added and the reaction product filtered and subsequently made into a slurry with hot water and again filtered and the resultant cake dried and crushed to produce terephthalic acid having a bulk density of 0.52. The latter was charged into an autoclave with ethylene glycol, zinc acetate and titanium oxide and the contents and the mixture heated in an atmosphere of nitrogen. When the reaction was complete the molten content was transferred to a polymerization vessel and polymerized for three hours under a reduced pressure at 285 DEG  C. in the presence of phosphoric acid and antimony trioxide.  Other examples are given.ALSO:Polyesters are produced by reacting terephthalic acid or a mixture of terephthalic acid and at least one different organic dibasic acid with a glycol and polymerizing the reaction product by heating under reduced pressure wherein the acid or acid mixture is compressed and thereafter optionally crushed, the compression and crushing being such as to give a product having a bulk density of at least 0.8 and an average particle diameter of not more than 8 mm.
