IPC: A63F3/02
Filed: 1970-01-23
Abstract: 1,225,948. Forecasting apparatus. R. J. WOOD. 23 Jan., 1970. No. 32171/70. Addition to 1,214,871. Heading A6H. Apparatus for forecasting football match results comprises one or more boards a, Fig. 1, bearing a pattern of parallel-sided, tapered or part spherical openings c, and correspond ingly shaped numbered counters which are a press-fit in the openings. The openings may be replaced by simple marks, pegs to fit holes in the counters, or magnets to attract metal counters. Each match is denoted by a set of two like-numbered counters installed on the board(s), the sets being consecutively numbered. To forecast eight draws, the user predicts a result for each match, and removes both appropriate counters for a draw, or one counter for a home or away win. All the removed counters are shaken together in a container and removed one at a time until eight differently-numbered counters are obtained to form the first "line" of the selection. Other types of selection are made in a similar manner. To forecast the results of a pre-determined number of specified matches each set of likenumbered counters comprises three groups of two counters, a group representing a home win, away win or draw. The groups have a distinctive colour, shape or marking. One board may be used for each group.

Abstract: 1,226,649. Centrifugal strainers. KRAUSSMAFFEI A.G. 8 Nov., 1968 [15 Dec., 1967], No. 53080/68. Heading B1D A suspension undergoes a preliminary separation in a centrifugal strainer 2 or 3 removably mounted in a hollow perforated member 12 secured to the shaft 14. Next, the suspension creeps up the walls of a centrifuge 5; the separated liquid forms a film adhering to the rounded surfaces of annular members 4 while exiting radially outwardly into chamber 16 through gaps 10, the solid residues continuing to travel upwardly and eventually leave ing near the top of the centrifuge, e.g. via a discharge zone 11. As described, the strainer is hemipsherical (shown as "3") or frustoconical ("2") and is reinforced by rings 3a or 2a, being supported by members 17-19. A baffle 20 provides a narrow gap 21, which prevents excessively rapid flow from the strainer 3 to the centrifuge 5.

[Also in Division C3] Biaxially oriented films having greater orientation in the longitudinal direction are prepared by extruding and stretching compositions comprising (a) 70 to 95 weight per cent of a crystalline α-olefin polymer and (b) 30 to 5 weight per cent of an additive having a drop softening point above 70‹ C. and which is a terpene resin, hydrogenated hydrocarbon polymer or compatible modified rosin, to form films with a Gardner haze of less than 5%, a 45 degrees specular gloss of greater than 70 and being capable of forming a twist wrap which will retain a twist of at least 0À5. The films may have a higher degree of stretching in a longitudinal direction, which may be imparted by direct stretching or by differential shrinking. Preferably, the films are stretched equally in longitudinal and transverse directions, e.g. by the " bubble " process, and allowed to shrink transversely at elevated temperatures while restrained from longitudinal shrinkage, preferably by passing over heated rollers under conditions permitting controlled shrinkage. The films may be surface oxidized, or may contain antistatic agents, e.g. amines and glycerides, and may be treated with a corona discharge. In examples, compositions comprising polypropylene and hydrogenated poly-#-pinene, optionally with glyceryl mono- and distearates and bis-(2-hydroxyethyl) myristyl amine, are formed into tubular films by the " bubble " method and subjected to differential transverse shrinkage.

Abstract: 1301527 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 28 May 1970 [29 May 1969] 25862/70 Heading H4K  A line scanner for a computer controlled exchange comprises one memory circuit and one identification circuit per line, which circuits are connected in a lock-out chain such that the computer is only called in upon a change of line state occurring whereupon all those lines that have changed state are then examined in turn. Each line circuit includes a supervisory device, e.g. relay M whose contact is connected to an input f of the associated memory circuit RC. The latter incorporates a bi-stable V1 which is cleared periodically by a commonz pulse and then is set, if the line has become busy (input f and delay RC to allow for transients), by the appearance of a common g pulse. An output is thus obtained at u for opening gate G7 in the associated identifier circuit IC whose outputs p, q, r provide a coded indication of the identity of the line. The circuits are connected in a chain so that the n output is applied to output b whereby the gate G7 in all the succeeding IC's is inhibited (b output is connected to a input). The b output of the last IC circuit is connected to the computer so that this now receives a start signal. The computer examines the S lead (multipled to all RC circuits) to determine whether this is the first time that the line is in the busy state. This is indicated by the "1" setting of V1 and the output of G7 via G6. The computer therefore reads-off the identity of the IC circuit and pulses the common e conductor whereby V2 sets to "1" and gate G4 is closed. The u output is then removed whereby the "1" on the IC b output and therefore on the a input of the succeeding IC is removed so that an IC lower in the chain may mark its outlets p, q, r if its associated time has become busy. When the line goes free V1 will stay at "0" when it is next pulsed at z so that gate GS opens to mark the u output again. This time there is no S output however, so after the computer reads off the identity, it pulses common lead n thereby restoring V2 to "0" and thus completes the clearance of the memory circuit. The identification outlets p, q, r are multipled to a set of binary coded leads (Figs. 2 and 4, not shown). The computer may address a particular memory circuit, e.g. for test purposes, by pulsing its f lead over a binary coded multiple (Fig. 6, not shown) and then comparing the coded output from the IC with the input code. The RC's may include a set of bi-stables which can be set so as to allow the test to be made after a certain delay (Fig. 7, not shown). Finally, each RC may incorporate a subordinate chain of RC's (but only one IC) pertaining to different functions of the line, each line's group of RC's being scanned in turn by selective energization of a set of e conductors in a manner akin to that described above (Fig. 5, not shown).
