Abstract: 1323795 Blocking press INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [11 May 1970] 26037/71 Heading B6J. In a blocking press the heatable die 32 is carried on a plunger 60 subjected to a constant downward pressure from air-spring 50. A cam 66 operating on a follower 62 permits controlled downward movement of the plunger and subsequently causes a return movement of the plunger. The cam is operated through a half revolution clutch 79 controlled by solenoids 80, 81 such that the die 32 remains in contact with the foil 20, Fig. 1 for a predetermined period. The die is supported on heat conductors 34 and 36 and is insulated from the plunger by barrier layers 38, 29. Electric heating elements 31, 39 are included. The press is exemplified in a process for transferring a layer of magnetizable material from a foil 20 to credit cards 10 fed from a hopper 12 and by rollers 16 on to anvil 40 beneath the plunger 60.

Junction boxes; binding-posts and terminals ; continuity couplings.-Junction boxes are built up of a number of interchangeable) units to the size or arrangement required. Each unit consists of a rectangular box b having removable covers r to the top and two or three sides, and a cable entrance c in the remaining side. A row of terminal. pillars j' is inserted diagonally in each unit, and standard links o are used to couple corresponding terminals together. The units are bolted together by the bolts of the covers which have been removed. When the junction is completed the whole is filled with bitumen to seal the cables and fix the terminals in place. The cable entrance c is a tubular extension into which a conical metal bush d comprising a packing gland is inserted. The inner armouring e<2> is laid upon this, and a conical washer g of wedge section is laid over the former, followed by the outer armouring e<1>. A clamping plate h is forced upon the whole to complete the joint. The continuity of the coupling is ensured by a lug on the conical washer, which is connected by a wire to similar lugs on the remaining units of the junction. The terminals, Fig. 3, are each mounted upon porcelain blocks k fixed by screws to a metal plate m. They comprise a clamp n for one core of the cable, which consists of a screw eye, through which the core is threaded, having projecting wings n<1> so that it may be drawn into close contact with a shaped surface on the side of the terminal pillar.

Title: Method of improving alcoholic liquors
IPC: C12H1/16
Filed: 1965-06-22
Abstract: The taste of alcoholic liquors is improved by subjecting the liquor to cavitation resulting from agitation of the liquor at a high rotational speed (for example, vanes rotating at between 6000 and 9000 r.p.m.) at a temperature not in excess of 42 DEG C. for a period of time not in excess of 20 minutes, whereby there is achieved rapid mellowing of the liquor with no impairment of its characteristic flavour.  The method may be employed to improve the palatability characteristics of a mixture of a superior grade of alcoholic liquor with an inferior grade of compatible liquor. Preferably the temperature is maintained in the range from 0 DEG  to 25 DEG C. by admixing with the liquor a sufficient amount of a volatile inert liquid refrigerant such as liquefied nitrogen. Alcoholic liquors mentioned: a mixture of 1/3 (by volume) of sak<\>ae and 2/3 of grain alcohol optionally with the inclusion of either 10% of 25 degree shochu or 10% commercial whisky, a mixture consisting of 75% of new bourbon whisky and 25% of charcoal-aged bourbon whisky, a blend of grape wine with fortifying alcohol, new bourbon or rye whisky, inferior whisky, sak<\>ae, and grain alcohol.

[Class 124] [Also in Group XXII] To produce travel the cylinder 1 of an internal combustion road rammer is provided with an inclined guide 7 for a weight 6 which is pressed upwards by a spring 4. There would normally be one weight on either side of the cylinder 1 and a handle 17 secured to each weight and thereby less subject to concussions from the rammer. To vary the length of the jumps the compression of the spring may be varied or the inclination of the guide varied by an adjusting screw or by the piston of a cylinder 19, Fig. 6, the pressure in which varies with that in the main cylinder of the ram. In another modification the return of the weight 6 is prevented by a ratchet 11, Fig. 4, until the rammer has fallen and the ratchet is automatically released by a rod 12. The device may also be mounted on a ring 16, Fig. 7, so that it can be rotated about the rammer, the handles being mounted on this ring.

[Class 39 (i).] The connection between a supply conductor and a leading-in wire of a discharge device such as a lamp, R÷ntgen-ray tube or a thermionic valve is protected by a tube of insulating material which extends within a cap cemented to the end of the device. Twisted leading-in wires 7, Fig. 1, and the conductor 12 of a lead-cased cable are connected together through a sleeve 8 provided with grub screws 9, 13. A tube 14, formed of the material known under the Registered Trade Mark of " Bakelite" or of paper impregnated with shellac, encloses the sleeve 8 and abuts against the end 15 of the lead casing. It is housed within a brass cap 16, which contacts with the earthed lead casing. Connection between the cap and the lead casing may be effected by a metal sleeve or a helical spring adapted to bridge a gap therebetween or by means of a flanged nut 18, Fig. 3, which serves to grip the flared end 20 of the casing. For high voltages, the length of the tube 14 is increased and is adapted to screw into the cap. A metal covering connected with the lead casing or a body at earth potential, is provided when the cap is made of insulating material. The interior of the stem 2 may be filled with insulating material and the invention is applicable to tubes in which the glass stem projects from the tube.
