Abstract: 1,172,046. Copy grinding turning tools. K. HERTEL. 15 Jan., 1968 [17 Jan., 1967], No. 2181/68. Heading B3D. A copying machine for grinding a turning tool 23 comprises a grinding wheel 3, an adjustable arm 8 rigidly connecting a ball joint 10 and a bearing plane 11 which lie in a common plane, a swivel arm 16 mounted on the ball joint, a template 19 having the nose angle 22 of the tool to be ground and mounted on the swivel arm for engagement with the bearing plane, means for clamping the tool to be ground to the swivel arm, a slideway 7 to allow pivotal movement of the adjusting arm 8 about an axis 26 extending parallel to the grinding plane and perpendicular to the line of alignment 12 between the centres of the bearing plane and ball joint, and a slideway 1 for adjusting the spacing between the grinding plane and the centre of the line of alignment. In Fig. 2 (not shown), the machine is set for grinding a tool without a nose radius, the pointed tip of the tool being in line with the centre of the line of alignment 12 as indicated by the tip of an indicator (36) which is retracted before grinding is commenced. The tool is pushed beyond the tip of the indicator a distance corresponding to the amount to be ground off and then clamped. For adjusting the clearance angle, the adjusting arm 8 is displaced on the slideway 7 which is calibrated at 45. Grinding is effected by manually swivelling the arm 16 and pressing the tool against the grinding wheel until the template 19 bears against the bearing plane 11. In Fig. 3 (not shown), the machine is set for grinding a tool with a nose radius, the tip of the tool being set beyond the line of alignment 12 by an amount equal to the desired radius plus the amount to be ground off; the nose radius is set by displacing the assembly relative to the grinding wheel on the slideway 1 which is calibrated at 43.

Abstract: 1536512 Polyphenylene ethers GENERAL ELECTRIC CO 20 Jan 1977 [23 Jan 1976] 02248/77 Heading C3R A process for preparing polyphenylene ether compositions comprises (a) oxidatively coupling a phenolic monomer in the presence of an organic solvent; a chelate complex of the formula wherein L in a ligand derived from an #- hydroxyoxime, e.g. benzoin oxime, Mn is manganese (II) and x is at least 0À5; a base, e.g. sodium hydroxide and optionally a primary or secondary amine to improve the reaction rate, (b) adding a non-solvent, e.g. methanol to the reaction mixture of (a) to precipitate the polymer and catalyst which together comprise the composition. The ligand L may have the formula wherein R a , R b , R c  and R d  are selected from hydrogen, cyclic or acyclic organic radicals and n is 0 or 1. The process may include the step of resolving the reaction mixture into two phases by adding water and a quaternary ammonium compound to the reaction mixture, agitating this mixture and separating the heavy aqueous layer from the light polymer/catalyst containing phase prior to the addition of the non-solvent used to precipitate the composition. In a typical example a composition is obtained by a process comprising the steps of: (a) coupling 2,6- xylenol at 80‹ F. for 110 minutes in the presence of oxygen, toluene as solvent, a manganese benzoin oxime as catalyst and an aqueous/ methanolic solution of sodium hydroxide and di-n-butylamine, (b) reducing the polymer content of the reaction mixture to 16% solids by adding toluene, (c) adding trimethyl-noctyl ammonium chloride and water and separating the phases by centrifuging and (d) adding methanol to the organic solvent phase to precipitate a polymer composition having manganese content of 208 p.p.m.

Abstract: 735,949. Automatic control systems. NORMALAIR, Ltd. Dec. 24, 1953 [Jan. 28, 1953], No. 2419/63. Class 38 (4). As shown, mass airflow to an aircraft cabin is maintained constant by a metering head (not shown) operating a two-way switch 2 to energize a relay 6 or 7 and run motors 4 in the appropriate direction to control air supply by adjustment of spill or throttle valves. Airflows of 10 or 60 1b./min. may be selected by a manually operated switch 14 energizing one or other of solenoids 11 to connect the corresponding metering head as in Specification 655,328. If it is desired to maintain a constant temperature within the cabin, a manually operated switch 16 is moved from the position shown to change over a relay 5 from the position shown so that motors 4 are then controlled by a two-way thermallyoperated switch 1 within the cabin. The switch 14 is set in the position shown for automatic temperature control. Then if airflow decreases to 10 1b./min., a switch 15 associated with the metering head opens and relay 5 is changed over so that the system ceases to maintain constant temperature and maintains a constant minimum airflow of 10 1b./min. During automatic temperature control switch 2 is still operative to prevent rise of airflow above 60 1b./min. and relays 9 and 10 safeguard against attempted operation of motors 4 in the reverse direction by switch 1 under these conditions. Operation of a switch 12 from the position shown permits manual control of motors 4 by switch 13.
