Abstract: 826,660. Box-making machines ; breaking creases in cartons. CHAMBON Ltd., ARMELIN E. R., and PLASKETT, A. F. G. Jan. 5, 1956 [Jan. 5, 1955], No. 360/55. Classes 18 and 94(1). Apparatus for forming tubular carton shells from sheet material 1, Fig. 1, having fold lines 2 comprises a crank 80 and connecting rod 79 for reciprocating a plunger 71 to force a blank between guide bars 63, 64, Fig. 6, partially folding it about lines 2b, 2d, with fingers 112, 113, driven in timed relation with the plunger, completing the folding operation to form a flattened shell 3 and, at the other end of the channel C, Figs. 7, 8, blades 116, fingers 167 and rollers 182, 183 operate to open and re-flatten the shell about the unused fold lines 2a, 2c, after which a trough 184, arms 185 and rollers 182, 194 open and re-flatten the shell about the first fold lines 2b, 2d. A pre-creased web of material 1, Fig. 1, is drawn into the machine continuously by rollers 4, 5 one having recesses spaced to correspond with the spacing of the creases, and is fed intermittently by rollers 12, 14 to guillotines 46, 62. The severed blank is pushed into the channel C by the plunger and. as the upper part of the blank is folded downwardly, it meets a gumming blade 83 (not shown), carried by the plunger carriage. As the plunger withdraws the gumming blade is stripped rapidly from the carton, a gumming roller 95 is advanced to present fresh adhesive to the blade and the blank, in tending to unfold, is prevented from returning by retaining catches 110, 111, Fig. 6. The folding is then completed by the fingers 112, 113, which are driven through cams and linkwork so as to move in arcs of circles whose axes lie on the axes of folding, thus eliminating rubbing. Succeeding cartons push the earlier ones through the channel C, the adhesive drying on the way, and after being gripped successively by paris of blades 128, 129 ; 130, 131, Figs. 7, 8 the lower edge of the released carton is engaged by a set of fingers 167, which force the carton up against blades 166, thus opening and refolding it, to be flattened between rollers 182, 183. After emerging, the upper edge meets the inverted trough 184 and the lower edge is forced forward by oscillating arms 185. The space being limited, the carton re-opened, is refolded on the original lines, re-flattened by rollers 182, 194 and fed between two split endless belts 195, 199, Fig. 2, being sliced into individual cartons by continuously rotating circular knives 203, 204. Specification 826,661 is referred to.

Filed: 1961-01-04
Abstract: 927,214. Semi-conductor devices. W. SHOCKLEY. Jan. 4, 1961 [Jan. 8, 1960], No. 408/61. Class 37. In a semi-conductor voltage regulating device having a base layer of material of one conductivity type, a surface layer of material of the opposite conductivity type and having a high resistivity is provided so that no breakdown takes place at regions of the junction remote from the centre. As shown in Fig. 1 a wafer 17 of P-type material is subjected to diffusion so that a very thin surface layer of N-type material 11 is formed so that the entire PN junction is within the N layer. Ohmic contacts 13, 14 are soldered to opposite sides of the N layer. At low voltages there is a high-resistance path around the periphery of the device through the high-resistance N layer. At high voltages breakdown takes place only in the region of the contacts because of the volt drop through the resistive layer. In a further embodiment (Fig. 3, not shown) the lower ohmic contact is replaced by a metal block acting as a heat sink and the device may be encapsulated. In a further embodiment the resistive layer does not extend down the side of the device (Fig. 5, not shown) but may be connected to the base by a solder (Fig. 6, not shown). The surface of the device may be channelled to increase the resistive path (Figs. 7 and 8, not shown) and the doping of the N layer in the region of the ohmic contacts may be greater than in the rest of the layer. Silicon is suggested as the semiconductor material.
