Abstract: 1332723 Composite packages UNILEVER Ltd 12 Jan 1971 [15 Jan 1970] 1376/71 Heading B8C A method of erecting a composite package of a plurality of containers 1 having substantially rectangular tops with outwardly extending rims 2 preferably having slightly radiused corners, and a carrier formed from a blank divided by two parallel fold lines 7 into a central panel 3 which covers at least a part of the tops of the containers, and two opposite side panels 4 the fold lines 7 being interrupted by slits 5 adapted to receive the rims 2 of the containers, comprises, maintaining the blank in position on top of the containers, folding each side panel downwards through an angle greater than 90 degrees towards the bodies of the containers and pushing the side panels downwardly and inwardly away from the centre panel. In this manner the rims of the containers are received in the slits of the blank. Arcuate slits 6 facilitate the folding of the side panels, the upper edges of which, as formed by the slits 5, engage beneath the rims 2. The width of a blank is slightly less than that across the containers from rim to rim. As shown in Fig. 2 a flat blank 3 is held down, by pressure members 11, on top of the containers while folding members 12 move downwards in direction A to bend the panels 4 around the rims 2 and open the slits 5 into which members 13 are inserted in direction B. The members 13 are then moved in direction C to press the panels downward until their upper edges, at the slits, snap below the rims 2. In a continuous process packaging machine the containers are carried on a conveyer 21, Fig. 4, having supports 22 for all sides of the containers which are preferably also supported at their sides by a pair of guide rails (35), Fig. 3 (not shown). Catches 25 on a conveyer 26 engage the blanks and move them at the same speed as the conveyer 21 while ploughs 24 progressively fold the side panels towards the container bodies at an angle of more than 90 degrees. A roller chain conveyer carries a number of pivotally mounted fingers 28 which are adapted to be pivoted downwards by guide rails 32, 33 and are adapted to approach, and retreat from, the container bodies.

Title: Method and apparatus for increasing writing rate of storage tube
IPC: G11C11/23
Filed: 1965-01-12
Abstract: 1,085,811. Cathode-ray storage tubes. TEKTRONIX Inc. Jan. 12, 1965 [Jan. 13, 1964], No. 1412/65. Heading H1D. In a bi-stable storage tube, particularly of the direct-view type described in Specification 992,178, in which the target 26 is bombarded with low velocity holding electrons from source 30 to permit the bi-stable storage of a charge image produced on the target by a high velocity writing beam, the writing rate of the tube is increased by preventing the holding electrons from bombarding the target during writing, and by momentarily increasing the velocity of the holding electrons after writing by means of an enhancement voltage greater than the first cross-over voltage, so that written areas of the target having a potential less than the first crossover voltage are charged to a potential above this voltage, after which the velocity of the holding electrons is decreased to permit conventional bi-stable storage. The momentary increase in the velocity of the holding electrons is possible since unwritten background areas of the target charge at a slower rate than the written areas and are not permitted to reach the first crossover voltage. The flood gun cathodes 31 may be connected to a three-position manual switch to effect cut-off during writing; application of a writing rate enhancement pulse whereby the cathode potential rises exponentially from - 70V to 0V in a time determined by the circuit including capacitor 48 and resistors 50, 52, and then remains at OV for directviewing storage; and erasure. Alternatively, for automatic operation, a blanking signal generator is triggered by the input writing signal to apply a negative voltage blanking pulse to the control grids of the flood guns, so that a capacitor connected to the flood gun cathodes charges to a negative voltage to increase momentarily the velocity of the flood electrons when the flood guns are turned back on by termination of the blanking pulse. As a further alternative, a negative rectangular pulse may be applied to the flood gun cathodes for writing rate enhancement.

Title: Improvements in or relating to processes for the refining of non-ferrous alloys
IPC: C22B15/00
Filed: 1951-01-19
Abstract: A process for the reduction of the content of metal impurities in finely-divided non-ferrous alloys consists in immersing and agitating the finely divided alloy in the cold in a bath consisting of an aqueous solution of a salt, the reaction of which on the alloy causes the impurities to pass into solution but does not substantially alter the proportions of the major constituents of the alloy.  This process may be accelerated by electrolysis using the material being treated as cathode.  Example is given of treatment of a bronze containing Sn 6.5 per cent, Sb 0.25 per cent, Pb 3.35 per cent, Zn 8.4 per cent, Al 0.3 per cent, Fe 0.18 per cent. Ni 0.55 and remainder Cu in a solution of copper nitrate and nitric acid in water, the removal of Al from a mixture of turnings of Al-base brass and Cu in a solution of copper chloride and hydrochloric acid in water.  In a further example the Pb content of anti-friction Sn alloys containing Sn 60.0 per cent, Pb 25.5 per cent, Zn 5.5 per cent, Sb 6.0 per cent, Cu 2.8 per cent is reduced in a solution of copper chloride and hydrochloric acid in water.

Title: Improvements in or relating to decoders for pulse code modulation systems
Inventor: CLEOBURY DONALD JACK
IPC: H04B14/04
Filed: 1963-01-15
Abstract: 1,007,669. Electric selective signalling. GENERAL ELECTRIC CO. Ltd. Jan. 15, 1964 [Jan. 15, 1963], No. 1785/63. Heading G4H. In a decoder for a receiver in a pulse code modulation system of the kind in which successive sample amplitudes are transmitted each as a series of, say, seven binary scale bits, the first four of the seven bits are temporarily stored in units 10-13 and then transferred to storage units 20-23 at about the same time that the last three bits enter units 24, 25 and 26. By this means the period for which the output signals J-Q are available is extended from the time of arrival of the last bit of one group to a point just before the arrival of the fourth bit of the next group. Generator 9 provides distributed pulses which are applied to diode gates 2-8 to distribute the pulses arriving at terminal 1 in turn on to seven leads. The first four pass to capacitor stores 10-13 and the last three to similar stores 24, 26. At a time just before the sixth pulse diode gates 15-18 are opened to transfer the contents of stores 10-13 to stores 20-23. Just after the seventh pulse the stores 10-13 are reset ready to receive the first pulses of the next group. Stores 20-26 are reset between the third and fourth pulses of the next group. The outputs J-Q are applied to weighted resistors so that a voltage is derived representative of the binary group received. This signal is stretched to occupy the whole group period and in this way the original waveform is reconstituted. In another form the transfer gates 15-18 are omitted, the bits stored in units 10-13 being read-out as the units are reset.
