Patent GB-1133571-A (GB)
Title: Improvements in or relating to, rotary indexing units
IPC: B23Q16/06
Filed: 1964-09-08
Abstract: 1,133,571. Indexing. A. P. L. THOMAS. 8 Dec., 1965 [8 Sept., 1964], No. 36672/64. Heading B3B. A rotary indexing unit for transporting workplaces to a series of single, or multi-, tool positions, comprises a detachable table (5), a concentric ratchet wheel 7, a pivoted pawl 8 spring-loaded towards the teeth, and means for rotating the table in each direction, in one of which directions the pawl engages one of the teeth and locates the table. The table carries fixtures and is rotated by a motor 14 through a belt drive and a worm 13. Overload on the motor is controlled by a slipping clutch in one of the pulleys or by currentcontrol. In operation, actuation of a push-button causes the table to rotate clockwise causing the pawl 8 to move out and actuate a switch 32 and stop the motor. As the table slows, a ratchet tooth momentarily actuates a reversing switch 33 to cause the table to move back and the pawl to come against a tooth face. Excess movement is taken up in a spring 24 by axial movement of the worm 13. To index the table through two or more teeth, a rotary stepping switch 38 is used in co-operation with manually-set switches 46. To reduce the noise of the pawl passing over the teeth, a solenoid 48 projects a pin 50 into an over-size hole 51 in the pawl to reduce its travel. The slipping clutch in the worm-and-pulley drive may be replaced by an electromagnetic clutch, the power of which may differ in forward and reverse drive by the setting of a potentiometer, or the forward drive may be the positive drive of a free wheel device. In a further modification, the ratchet teeth are mounted on the part 4.

Title: Method for preparing carboxylic acid anhydrides, acyl halides and mixtures thereof
IPC: C07C51/56
Filed: 1957-11-28
Abstract: Acid anhydrides and halides and mixtures thereof of a -b -unsaturated carboxylic acids are prepared by reacting a salt of an a -b -unsaturated acid of formula <FORM:0834357/IV (b)/1> where R is hydrogen or a methyl group, M is an alkali metal, alkaline earth metal, magnesium or beryllium and n is 1 or 2, with a carbonyl halide of formula <FORM:0834357/IV (b)/2> where b is 1 or 2 and X is chlorine or bromine, the two X's not being necessarily identical. One mol. of the halide is reacted with two molar equivalents of the acid anion to give the anhydride and with one molar equivalent to give the halide. Intermediate proportions give mixtures of the anhydride and halide.  The products are useful for polymer formation. The reaction may be carried out with or without an inert solvent and the halide may be added in gaseous form or in solution in the solvent.  Specified solvents include ethers, dioxane, ketones, saturated aliphatic and cycloaliphatic hydrocarbons, aromatic hydrocarbons and halogenated derivatives thereof.  Atmospheric, subatmospheric and superatmospheric pressures may be used.  The temperature may vary from the liquefaction temperature of the carbonyl or oxalyl halide to 100 DEG  C. or higher.  It is preferred to start at room temperature and then to maintain the temperature of the exothermic reaction below reflux temperature.  A polymerization inhibitor may be present.  In examples: acrylic anhydride is prepared by the reaction of phosgene or oxalyl chloride with sodium, potassium, lithium, barium, calcium or magnesium acrylate in hexane or benzene solution; methacrylic anhydride is prepared from sodium methacrylate by similar methods; an acrylyl chloride/anhydride mixture and methacrylyl chloride are also prepared similarly using appropriate quantities of phosgene.
