Title: Field effect transistor circuit incorporating a noise clamp
IPC: H03K19/0175
Filed: 1972-11-28
Abstract: 1374718 F.E.T. logic circuits ROCKWELL INTERNATIONAL CORP 28 Nov 1972 [17 Dec 1971] 54980/72 Heading H3T When a reference voltage (OV) is supposed to be present at node 2, a F.E.T. circuit 7, 8, responds to the OV level to turn on a F.E.T. 6, which connects the node 2 through a series F.E.T. 5 to a source of OV in order to remove unwanted (negative) noise from the node 2. This noise arises from logic gate 11 and others (not shown) like it, connected to node 2. The output of an input logic gate 3 is gated byF.E.T. 4 to node 2 in # 1+2  time. Simultaneously,F.E.T. 7 precharges the gate capacitance of F.E.T. 6, and this is discharged by F.E.T. 8 if a negative level (1) appears at 2, or retained if a Ov level (0) appears at 2 and fails to turn on F.E.T. 8. Subsequently (# 3+4 ) when OV at the node 2 is operative to control the output gates 11, and noise liable to br fed back, F.E.T. 5 is turned on to earth the node. F.E.T. 5 drain may be earthed or connected to # 1+2 . If a 1 appears at node 2, the negative noise merely adds to the negative level and no errors arise.

Abstract: 1431469 Packaging elements IDEMITSU KOSAN KK 27 Nov 1973 [28 Nov 1972] 55035/73 Heading B8P [Also in Division C3] Perishable foodstuffs, such as fruit, eggs, &c., are packaged between first and second sheets 11 and 15 of a foamed polyolefinic resin composition containing 30 to 60% by weight of calcium carbonate, calcium sulphite, calcium sulphate, calcium hydroxide, calcium silicate or mixtures thereof, the second sheet being a physicallyfoamed sheet and the first sheet being either a physically- or chemically-foamed sheet and provided with article-receiving recesses 12. The resin may comprise polyethylene, polypropylene, polybutadiene, polyisoprene, ethylene/ vinyl acetate copolymers, and mixtures of polyethylene and polybutadiene. The particle size of the calcium compound is less than 10 Á. The second sheet 15 may be formed by heating a mixture of resin pellets and the calcium compound to form granules which are heated in an extruder. A physical blowing agent, liquid butane or butylene, is introduced into the extruder and the resin mix extruded either directly into sheet form which may subsequently be perforated or into a 2 mm. rope which is processed to provide a fused network sheet form, Fig. 2 (not shown). The first sheet may be formed as described above but in which the mixture is directly extruded into sheet form, the sheet then being vacuum-moulded to form recesses 12. Alternatively, the first sheet 1, Fig. 1 (not shown), may be formed by kneading a heated mixture of resin, calcium compound, a foaming agent (e.g. azodicarboxylamide), and a cross-linking agent (e.g. 1,3-bis-(t-butyl peroxyisopropyl)benzene), charging the mixture into a die of a compression moulding machine to form a plate. The plate is subsequently cut to form sheets which are pattern stamped to provide the recesses. A package is formed by building-up layers of filled first sheets each overlain with a second sheet within a carton-board-lined case.
