Title: Paper folding machine
IPC: B31B41/00
Filed: 1962-10-16
Abstract: 989,654. Folding and collating sheets. L. L. MAYER, and B. R. KIRSCHNER. Oct. 16, 1962 [Oct. 18, 1961], No. 39211/62. Heading B6H. A method of collating sheet material by insetting includes the steps of causing a master sheet of a predetermined minimum stiffness to travel in a determined direction, and of feeding a second sheet of foldable material transversely across the direction of travel of the master sheet, whereby the master sheet engages while it is being fed and buckles the second sheet which wraps around the master sheet to form a collated assembly. A plurality of roller pairs 1-14 to n-14 are provided, the rollers 14a of each pair being driven. Sheets are fed by roller feeds from alternately opposite directions on to platform 34 so as to lie over the corresponding roller pairs, or they may be fed in sideways. Master sheets are fed in turn from a stack 56 to rollers 28, 14b and against a stop 32, thereby being buckled to pass between the rollers 1-14 and buckle the sheet lying over the rollers 2-14, the assembly passing between the rollers 2-14. This process is repeated at each roller pair, each sheet being folded around the driving assembly. The last sheet is an envelope blank, and the final assembly is buckled by a stop 32a so as to pass between rollers 82, 14b to envelope gumming and folding rollers 90, 92, 94. Each sheet feeder has an electric motor, and a control system is provided so that any particular feeder may be rendered inoperative. Each feeder motor stops when a sheet reaches collating position against a stop 38 below an electrical contact C. The master sheet feeder 40 operates only when there is a sheet in collating position correspondingly to all the feeders which are operative.

A method of continuously measuring the degree of baking of a self-baking electrode includes the step of measuring the voltage drop between a metal member 8, passing through both the unbaked, electrode-forming paste 2 and the baked mass 5 of carbon, and the peripheral metallic shell 1. The metal bar 8 is consumed with the carbon mass during operation of a furnace utilizing the electrode, e.g. a submerged arc furnace for producing metals or alloys. A three-phase furnace for producing calcium carbide is referred to. Contacts 6 and conductors 7 connect the electrode to an external circuit. Insulated and shielded conductors 10, 11 connect member 8 and shell 1 to a double moving element recording resistometer 9, for measuring the voltage drop, and conductors 12, 13, convey a measurement of the electrode current supplied, so that the resistometer 9 records the ratio C between these two quantities, as an indication of baking. Member 8 is connected via insulating tension rods to the reinforcing structure of the electrode (not shown). A detailed example is given, specifying dimensions and operating conditions.

Title: Process for the catalytic depolymerisation of polymer gasoline
IPC: C10G11/18
Filed: 1960-12-08
Abstract: The catalytic depolymerization of a polymer gasoline is effected at elevated temperature in the presence of a catalyst, which has been used for the cracking of heavier hydrocarbon oils, during the stripping of such catalyst prior to its regeneration. Although a fixed bed operation may be used a fluidised bed apparatus is preferred in which the catalyst is transferred to a fluidised bed stripper by a riser in the form of a dilute suspension in a stripping gas wherein a preliminary stripping is effected.  The polymer gasoline, e.g. obtained by polymerization of one or more C3-C5 alkylenes, is preferably introduced with the stripping gas into such riser so that hydrocarbons are stripped from the catalyst in the fluidised bed; the polymer may be introduced to the fluidised bed also.  The catalyst may be silica-alumina, the stripping gas steam and the temperature 450 DEG C.-540 DEG C.  The product is not necessarily identical with the original monomer.  In an example a butylene polymer yields C3 and C4 alkanes and alkenes. Specifications 718,578 and 765,261 are referred to.

Abstract: 422,991. Reproducing lenticular picture films. OPTICOLOR AKT.-GES., Glarus, Switzerland. Feb. 6, 1934, No. 3922. Convention date; July 6, 1933. Addition to 421,084. [Class 98 (ii)] In copying with a ratio other than 1 : 1, the apparatus of the parent Specification is modified by employing plane mirrors on opposite sides of the objective, spaced apart at different distances. These distances may be proportional to the change of scale. In the device shown, copying from the larger film 1 is effected on the film 2 by the objective 3, mirrors 4 .. 7 being arranged in pairs on opposite sides of the objective so that the images 3<1>1, 3<11>1, 3<1>2, 3<11>2 lie in opposite directions as seen from the objective. The images 3<1>2, 3<11>2 are arranged to occupy the same positions relative to the film 2 as the corresponding filter zones occupied during taking, or somewhat eccentrically thereto, as in Specification 422,983, to nullify unsymmetrical diffusions. If the apertures of the lenticular elements on the two films differ, the mirrors are arranged at other distances ; the condition to be observed is that the angles at which the films with their images are seen from the objective are the same on both sides. The gaps between the apertures of the objective seen from the film of larger size are arranged to coincide with the separating lines of the colour filter used in taking or reproduction.
