Filed: 1962-03-29
Abstract: 1,008,023. Welding by pressure; brazing. AMERICAN MACHINE & FOUNDRY CO. March 29, 1962 [March 29, 1961], No. 18932/65. Divided out of 1,008,021]. Heading B3R. In friction welding or brazing workpieces wherein relative movement is effected between the workpieces and the workpieces are brought into rubbing contact to develop heat by friction, a surface of a first metal is brought into contact with a surface of a different metal which dissolves in the first metal and forms an alloy therein, the first metal being aluminium, and the different metal being nickel or silver or the first metal being molybdenum and the different metal being nickel. In joining a stainless steel workpiece 10 to an aluminium workpiece 11 the workpiece surfaces 12, 13 are degreased in benzene or ultrasonically and the stainless steel surface is roughened by sand blasting. The roughened surface is spattered with nickel particles to form a thin nickel coating, is coated with nickel electrolytically or is provided with a layer of nickel fixed by a mechanical bond, by welding or pressing with a suitable tool. The aluminium workpiece is rapidly rotated and the stainless steel workpiece with its nickel coating is forced against it and the nickel film melts. The station of the workpieces is rapidly stopped and the workpieces are still pressed together. Layers of aluminium-nickel alloy and nickelsteel alloy form the weld. Aluminium may be welded to any steel coated with silver or nickel, stainless steel coated with nickel may be welded to molybdenum and " Monel " (Registered Trade Mark) coated with nickel may be welded to aluminium. If the intermediary material wets the workpiece surface but remains as a thin film the process is called friction brazing. Specification 1,008,022 is referred to.

Title: Improvements in or relating to timer mechanisms
Inventor: MIDGLEY ALBERT HENRY
IPC: G04C23/16
Filed: 1958-06-16
Abstract: 929,117. Time-switches. MIDGLEY HARMER Ltd., and A. M. MIDGLEY. June 16, 1959 [June 16, 1958], No. 19194/58. Class 38 (5). [Also in Group XXIX] A timing mechanism for e.g. cookers, has two spindles, each capable of rotary motions for setting the starting and stopping times of the operation and each further capable of axial motion to actuate the switch mechanism, as disclosed in Specification 768,842 (electric switch) or in Specification 846,398 (gas valve). The start and stop times are both set by a common spindle. The start spindle 3 has a wheel 6 set to the starting time and meshing with a further wheel 7 carrying hand 37 displaying the starting time. Wheel 8 is driven by the clock mechanism so that when the clock time as indicated by hand 36 and start time (hand 37) coincide the stud 9 enters a hole in wheel 6 and enables the entire shaft 3 and its wheel to move axially under control of spring 39, thus switching on as disclosed in the Specifications referred to above. The wheel 17 is initially moved to a position corresponding to the start time (due to the wheel 7 engaging wheel 6) and remains stationary until this time, when the shaft 3 moves axially as previously stated and is unlocked from a fixed gear 12. The shaft 3 rotates at clock speed driving wheel 17 into coincidence with wheel 16 (which has been set at stop time-hand 38) whereupon the stud 18 enters a hole in wheel 16 and the shaft 15 moves axially to operate the " stop " mechanism. An alternative indicator arrangement is disclosed and employs coaxial dials behind a clock hand. Setting is achieved as follows: a knob (not shown) is pushed in and locks gears 11 and 20 and drives gear 7 by a train including gear 6. When the setting knob is turned clockwise, the abutments 24 and 23 (on gears 7 and 19 respectively) engage and both the start and stop gears 6, 16 move together to the stop time. The knob is then turned anticlockwise to bring the start gear 6 back to the start setting, the stop setting remaining stationary due to the loose coupling 23, 24. The knob is now pulled out and sets the switch mechanism and unlocks gears 11 and 20.

Title: Improvements in or relating to the separation of terephthalic and isophthalic acids
IPC: C07C51/48
Filed: 1956-06-21
Abstract: Mixtures of terephthalic and isophthalic acids are separated by selectively dissolving the isophthalic acid in methanol at elevated temperature, separating the resulting solution of isophthalic acid from the undissolved terephthalic acid, recovering the terephthalic acid, and recovering isophthalic acid from the solution.  The separation may be effected by grinding the mixture and agitating it with 80 to 100 per cent aqueous or absolute methanol at 40 DEG  to 60 DEG  C., cooling to below 50 DEG  or 40 DEG  C. to precitate any terephthalic acid which may have been dissolved, and filtering to obtain terephthalic acid.  The filtrate, after treatment with charcoal and cation exchange resin, may then be cooled to a temperature from the melting point of methanol to 30 DEG  C. to obtain solid isophthalic acid.  The separation may be conducted at pressures of from 1 to 20 atmospheres and in a batch, intermittent or continuous manner.  The mixture of acids may be prepared by oxidizing mixed xylenes in acetic acid and in the presence of manganese bromide with air and washing the solid mixture obtained with acetic acid to remove phthalic acid.  An example is given.
