Patent GB-688129-A (GB)
Title: Improvements in amines and in their manufacture
IPC: C07C45/46
Filed: 1949-12-09
Abstract: The invention comprises N-alkyl or N,N-dialkyl-o -phenyl (or substituted phenyl)-tertiary butylamines and their salts.  The invention comprises also the preparation of a 1,3-diphenyl - 2,2 - dimethylpropanone - 1 by benzylating isobutyrophenone, e.g. with a benzyl or substituted benzyl halide; reaction of the ketone so formed with an alkali metal amide to produce an a a -dimethyl-b -phenyl-propionamide which is then reacted with an alkali metal hypohalite to give a di-(b -phenyl-a a -dimethyl-ethyl) urea; decomposition of the urea with alkali to give o -phenyl-tertiary butylamine, e.g. with a alkali or alkaline earth metal, oxide or hydroxide and water; condensation of the o -phenyl-tertiary butylamine with an aromatic aldehyde followed by reaction of the Schiff base so formed with an alkylating agent; and finally, hydrolysis of the product to yield an N-alkyl or N,N-dialkyl-o -phenyl-tertiary butylamine.  The isobutyrophenone used as starting material may conveniently be made by acylating thiophene-free benzene with isobutyryl halide using aluminium chloride or bromide, or stannous chloride as a catalyst.  In an example, isobutyrophenone, prepared as above, is reacted with benzyl bromide in the presence of sodamide to give 1,3-diphenyl-2,2-dimethylpropanone-1 which is heated with sodamide to give a a -dimethyl-b -phenyl propionamide; this is treated with potassium hydroxide and bromine to produce di-(b -phenyl-a a -dimethylethyl) urea which is then heated with calcium hydroxide to 240-260 DEG  C. with gradual addition of water to yield o -phenyl-tertiary-butylamine.  In another example, o -phenyl-tertiary butylamine is refluxed with benzaldehyde and ethanol to give a Schiff base which is heated in a sealed tube p  with methyl iodide and the product hydrolysed to yield N - methyl - o  - phenyl -tertiary butylamine.  The compounds of the invention may be converted into salts with acids such as hydrochloric, sulphuric, phosphoric, tartaric, lactic, oleic and palmitic acids.  The phenyl radical may be substituted by alkyl, alkoxy or hydroxy groups, for example, the benzylation step may be carried out with dimethoxybenzyl bromide so as to produce the corresponding dimethoxyphenyl - tertiery butylamine.

Title: An acoustic-optical call indicator panel
IPC: H04M19/04
Filed: 1961-09-04
Abstract: 954,250. Electric selective signalling systems. G. CONFORZI. Sept. 4, 1961 [Sept. 2, 1960], No. 31711/61. Heading G4H. A bell calling system in which each of a plurality of push-buttons is associated via a relay with a lamp on an indicator board is characterized in that each relay is slow-to-release whereby upon depression of any push button the associated relay picks up immediately to energize the associated lamp but upon release of the push button the lamp remains energised for a short period until the relay releases. This relieves the observer from having to reset the indicator after each call. In a first embodiment push buttons P 1  to P 6 , Fig. 1 are associated with relays S 1  to S 6  and lamps L 1  to L 6 . Depression of a push button establishes a series circuit from a source S via a bell C 1  the depressed push button, and the winding of the associated relay which (a) connects the source S to the primary of a transformer T and (b) connects the associated lamp to the secondary of the transformer. Upon release of the push button the bell circuit is interrupted but the lamp remains energised until the relay releases. In the second embodiment (Fig. 2 not shown) the bell is energised from the secondary of the transformer.

Abstract: 797,418. Cleaning metals. BENDIX AVIATION CORPORATION. Nov. 8, 1955 [Nov. 15, 1954], No. 31928/55. Class 82(2) An apparatus for cleaning ball bearings has means for subjecting the bearings simultaneously to the action of flowing cleaning fluid and vibration at ultra sonic or sonic frequencies. The ball bearing 43 is held by its outer race by a double-ended rotatable support 50, the inner race being free to revolve. A cleaning chamber 26 receives cleaning fluid from a diametrically offset pipe 49 so that the discharge through the ball bearing is vertical, the rotary component being great enough to rotate the inner race. The cleaning chamber has a transducer vibrator unit 33 attached, the latter being surrounded by cooling fluid circulated in a container 10. The cleaning chamber 26 is supported on a tray 14 by a vibration-damping resilient ring 28, the tray collecting the cleaning fluid which is discharged at 24. This tray is mounted on the container 10 by similar vibrationdamping means. The apparatus is grounded to earth static electricity and clips 64, 65 bond the parts of the apparatus together. In use, the inner race rotates, stopping without applying force if the race jambs with a grit particle. The operator then frees the particle by slight reverse rotation of the race. Thus no grit particles can become forced in the race tracks. Specification 797,417 is referred to.
