Abstract: ABSTRACT OF THE DISCLOSURE    A method of, and a device for, facilitating the threading in rapid succession of a series of perforated articles, for example small bags, boxes and other packages, onto a rod, especially a rod fixed at one end in a display unit for the articles.  The device includes an elongate support, which may be a flexible cord, having a tubular coupling at one end which is engageable over the free end of the rod, the tubular coupling being dimensioned externally so that it passes through the perforations in the articles.  A stop member may be provided at the other end of the elongate support and, when the latter is in the form of a flexible cord, the stop member may be removably engageable in the tubular coupling so that the device can be formed into a closed ring which can serve as a handle for carrying articles threaded onto the elongate support.

Abstract: ABSTRACT        Apparatus for inserting terminals in strip form into cavities in a coil bobbin comprises first and second slide assemblies in parallel side-by-side relationship.  A strip of terminals is fed towards a terminal insertion zone of the apparatus by a feeding device which is actuated during movement of the first slide assembly through a working stroke.  Shearing means for shearing terminals from the strip are also actuated by the first slide assembly and serve to place the sheared terminals in front of inserters carried by the second slide assembly.  Finally, during the working stroke of the first slide assembly, the inserters move relative to the second slide assembly towards the insertion zone to advance the sheared terminals in a guide tube of the second slide assembly.  During the working stroke of the second slide assembly, the guide tube is moved up to the workpiece and thereafter, the guide tube remains stationary as the inserters push the terminals into the cavities in the workpiece.

Abstract: Abstract:         A process and apparatus are provided for removing a first polar gas from a mixture thereof with a second gas. The gas mixture is passed through a sorbent bed having a preferential affinity for the first polar gas and the first polar gas is sorbed thereon so as to produce a gaseous effluent which has a concentration of first polar gas therein below a predetermined maximum. Then the polar gas sorbed on the sorbent bed is removed therefrom by application of microwave energy, at a temperature at which the sorbent is transparent to such energy, while passing a purge flow of gas in contact with the bed to flush out desorbed first polar gas from the bed. The bed is allowed to cool to a relatively efficient temperature for adsorption. The gas mixture is then again passed in contact with the bed. If two beds are used, one bed can be desorbed while the other is on-stream thereby maintaining a substantially continuous flow of effluent gas.

Abstract: ABSTRACT          Low calorie beer is prepared by introducing into the brewing process a debranching enzyme obtained from rice, a traditional brewing material.  The debranching enzyme re-duces the calorie content of the beer by cleaving 1-6 link-ages of unfermentable limit dextrins to form alpha 1,4 dex-trins which can be converted by grain enzymes to sugars that can be fermented  by brewer's yeast.  She enzyme may be in-troduced into the brewing process by adding enzyme extracted from rice to the mash; or by adding the debranching enzyme previously isolated from rice to the wort prior to fermenta-tion or preferably by adding the debranching enzyme to wort in the fermentor.  The debranching enzyme may be obtained from commercially polished dry milled rice.  Methods of isolating the enzyme and a storage stable form of the enzyme are disclosed.
