Title: Improvements in folding or collapsible cardboard boxes
Inventor: UPWARD ERIC WILLIAM
IPC: B65D5/22
Filed: 1948-12-08
Abstract: 656,015. Boxes. TAYLOWE, Ltd. Dec. 8, 1948, Nos. 31800/48 and 3444/49. [Class 18] A blank for a folding cardboard box, Figs. 1, 3, is folded along lines 1 to provide two layers, the free edges of which may be joined by a flap 2. The double blank thus formed is folded so that portions 4a, 4b form a doublelayer base and the portions 5a, 5b form integral doablelayer side walls. Wing portions 6a, 6b are folded inwards to provide doublelayer end walls, diagonally creased extensions 9 and flaps 11 on the side walls being infolded between the portions 6a, 6b. Tongues 12 and 14 engage in recesses 13 and 15 to lock the walls in position. Modifications are described in which the tongues 13 extend underneath the base layer 4b, or they may be replaced by an additional panel underlying or abutting the base layer 4b. Alternatively the panel 6b may extend to the lower base layer 4a so that its free edge is inserted between the edge of the layer 4b and the portion 6a. In a further modification the outer wing portion may be folded outward and a flap inserted between the base layers, said wing portion in this case being integral with the layer 4b. A lid portion may be formed integrally with the box blank, Fig. 11. One of the end wings 6b is continued to provide a lid panel 20 separated by a panel 21 so that when the box is folded the panel 21 lies against the double end wall. Slits 22 form tongues for engagement with the recesses 13. The lid may have a slit 24 and a crease 25 so that it may be folded to stand upright for display purposes. In a modified form the lid is folded from a separate blank and may be held in position by a flap which is tucked in between the two base layers.

Title: Improvements in or relating to magnetic circuits for travelling wave apparatus
IPC: H01J23/00
Filed: 1952-12-17
Abstract: 726,823. Magnets. WESTERN ELECTRIC CO., Inc. Dec. 17, 1952 [Dec.29, 1951], No. 31982/52. Class 35. [Also in Group XL (a)] Travelling wave apparatus is provided with a magnetic circuit for focusing comprising a pair of polepieces energized by a magnet and defining an air gap in which the delay line is positioned, and a " flux guide " of magnetic material extending between the polepieces and effectively encompassing the air gap, the flux guide being of varying thickness so as to focus the beam in a desired manner. In one form, Fig. 1, a travelling wave tube 16 having heat radiator 20 is positioned within and supported by two U-shaped magnets 10, 11 with common cylindrical polepieces 12, 13. The gun 17 is surrounded by a magnetic shield within the tube and the assembly is positioned within polepiece 12. The tube construction may be as described in Specification 697,550, [Group XL (a)], in which the gun shield is outside the tube envelope. 23, 24 are input and output wave-guides and may assist in supporting the tube. The flux guide may be two magnetic (steel) plates 27; they are linearly tapered from each end to the centre and are wide compared to their separation and serve to make the flux lines straight and the field uniform as described with reference to Figs. 2, 3 (not shown). A cylindrical flux guide is theoretically better than two plates but has the disadvantages that (a) large apertures therein would be necessary for the input and output wave-guides or, (b) if coaxial terminals are employed for coupling the input and output the tube is not accessible for inspection. Impingement of the electrons on the helix near the collector, due to space charge radial debunching, is prevented by using a strong magnetic field; the field should, however, be weaker along most of the helix to allow the electrons to pass close to the helix where the interaction is most favourable. Thus the flux guide cylinder or plates may be thickest near the gun and thinnest near the collector, Figs. 5, 6 (not shown). The thickness variation may be exponential or linear. In another form, Fig. 7 (not shown), the form of Fig. 1 is modified by shaping the right hand half of the flux guide to deviate from the linear increase in thickness by an exponentially increasing amount so that the field increases exponentially from the midpoint to the collector. Permanent or electromagnets may be used. The variation in thickness of the flux guide may be modified for example in devices where small signal theory does not hold.

Title: Matrix generators
IPC: G09G1/10
Filed: 1971-07-08
Abstract: 1333139 Cathode-ray tube displays CORNING GLASS WORKS 8 July 1971 [16 July 1970] 32090/71 Heading H4T In a character display system of the type in which the characters are formed by intensification of the beam of a cathode-ray tube at selected "dot" positions in a dot matrix as the beam is indexed (deflected) from dot-to-dot, the indexing is controlled by index pulses in timed coincidence with clock pulses when the beam is not to be intensified and by index pulses time spaced by a dwell time when the beam is to be intensified. This arrangement avoids the "wasted" time intervals of prior art systems which employ constant interval index pulses. As shown in Fig. 1, a clock 18 supplies clock pulses, Fig. 5a, to NAND gates 19, 22 which have as second inputs the intensity level signal and its inversion (via inverting amplifier 21) respectively. When the intensity level signal is "off" the clock pulses are supplied via gate 19 to OR gate 20 the output of which operates a counter 14 supplying the beam indexing signals via D/A converter 15 and deflection amplifies 16 to the X and Y deflection coils 13, whereas when the intensity level signal is "on" gate 22 conducts and supplies the clock pulses to gate 20 via a counter 23 which introduces the required dwell time delay. This period td is shown in Fig. 5b which also shows the indexing of the beam over twelve dot positions of which the 1st, 4th, and 5th, 7th, 8th and 9th and the 12th are each intensified for the period td. The counter 23 may be replaced by other suitable delay circuits such as monostable multivibrators or delay lines.
