Title: Treatment of rubber surfaces
IPC: C08J7/12
Filed: 1962-01-12
Abstract: A soft vulcanized rubber composition is given a hardened surface finish by treating with a solution of an N-halo-imide of a dibasic organic acid.  The imide is preferably dissolved as a saturated solution in acetone.  In an example a sheet of carbon black containing natural rubber was cleaned and the surface treated 12 times with a saturated solution of N-bromo-succinimide in acetone. The surface of the sheet is thus halogenated.

Filed: 1941-02-03
Abstract: 544,180. Control systems for resistance welding &c. BRITISH THOMSON-HOUSTON, CO., Ltd. Feb. 3, 1941, No. 1371. Convention date, Feb. 1, 1940. [Class 38 (iv)] Inductive control; switching control. Rapid elimination of the inductance of a saturable seriesconnected reactor 15, is obtained by exciting its saturation winding from a dynamo-electric machine 19 principally excited by armature reaction, of the kind described in Specification 539,835, for example, and provided with a controlling exciting winding 20. The supply to electrodes 11, of a butt-welding machine, for example, is initiated by start-button 35 energizing self-sealing relay 37 and thereby the winding 20, a resistance 31 being adjusted to determine the saturating current produced by the machine 19. Welding current strength characteristic of a completed weld energizes a relay 39 through a series transformer 40 to de-energize winding 20, whereupon a residual effect in the machine 19 reverses the current in the saturating winding. To eliminate arcing on opening the main switch 15 or removing work from the electrodes 11 due to stored energy in the transformer or inductance 16 a relay may be connected across the reactor to short-circuit the transformer when the reactor is not saturated. The controlling winding 20 may be excited from the A.C. supply through rectifiers and its circuit may include back contacts of the short-circuiting relay in series with contacts of a start switch, back contacts of which are in series with the relay winding.

Abstract: 1,207,111. Removing residual meat from bones. CANADA PACKERS Ltd. 9 Jan., 1969, No. 1384/69. Heading A2U. Residual meat remaining on bones from which the major portion of the meat has already been removed is extracted and formed into a slurry by tumbling the bones together with an aqueous liquid, preferably brine, in a rotating watertight container such that the residual meat is abraded from the bones by the combined action of the liquid and of the bones falling and rubbing repeatedly on themselves, the resulting meat slurry being subsequently drawn off from the cleaned bones. A brine concentration of between 1 and 15 per cent is found to be suitable, a 5 per cent solution being preferred, and the quantity of salt brine is determined such that the brineto-bone ratio is between 0.5 and 2.0 parts by weight per part of bone, a ratio of 1 : 1 being preferred, the resulting slurry then containing between 2 and 5 per cent protein. Examples are given of both pork and beef slurry when prepared by the method, either of which can be incorporated directly into a sausage mix.
