Abstract: 1501259 Cutter-bar type harvesting platform DEERE & CO 12 Nov 1975 [13 Nov 1974] 46741/75 Heading A1F A harvesting platform for a mobile harvester has a flexible cutter bar 40 capable of following contoured ground which is attached to a frame of the platform by a plurality of transversely spaced parallel-type linkages 56 allowing up and down movement of the cutter bar and a driye mechanism 50 for reciprocating a knife 46 of the cutter bar is mounted on one end of the cutter bar so that it can move up and down therewith. The drive mechanism 50, of a conventional wobble type, is driven by a belt drive 100 which includes an idler mechanism 108 which provides the proper belt tension irrespective of the position of the cutter bar 40. Each support linkage 56 comprises two links 60 and 74. The link 74 is pivotally attached at one end 76 to a channel shaped support 58, the support 58 being open downwardly and rigidly fixed to the underside of the feed table floor 30, and pivotally attached at the other end 78 to a bracket 72 carried on a skid supporting the cutter bar 40. The link 60 is pivotally attached at one end 70 to the bracket 72 and slides within the support 58 at the other end. Z shaped tabs 62 projecting rearwardly from each side of the other end of the link 60 keep the link 60 within the support 58 and also act as stops to limit the downward movement of the links and hence the cutter bar 40. In the uppermost position the links sit within the support 58. An alternative pivot point 79 for the link 74 allows the cutter bar to be positioned further forwards relative to the feed table. A spring 80, or contiguous springs, of sheet form acts to bridge the gap between the cutter bar and the feed table floor and also to counterbalance part of the weight of the cutter bar. Specification 1501260 is referred to.

Abstract: 1,242,257. Stabilization of bagasse against mycelial deterioration. C. L. WRIGHT. 14 Oct., 1969 [16 Oct., 1968], No. 49162/68. Heading A5E. [Also in Divisions C3 and F4] Bagasse is stabilised against mycelial deterioration by substantially uniformly treating bagasse having a moisture content of less than 50% of the weight of the damp material with phosphoric acid or an organic acid selected from alkane monocarboxylic acids, aliphatic dienic monocarboxylic acids and aromatic monocarboxylic acids in such an amount to reduce the pH thereof to 4.5 or below. Suitable organic acids are formic acid, acetic acid, propionic acid, sorbic acid, benzoic acid, phenylacetic acid and p-hydroxy-benzoic acid. The pH value, which is preferably between 3.7 and 4.2, is suitably obtained by the use of 1-3% by weight of acid based on the solids content of the bagasse. The bagasse preferably undergoes treatment in the form of chips. The bagasse is conveniently impregnated in a tower at the top of which the bagasse is fed and in which liquid acid or the acid in solution is sprayed into as the chips fall.

Title: Digital information storage apparatus

Abstract: 1,134,744. Superconductive storage apparatus. G. F. JONES, and G. R. HOFFMAN. 19 Nov., 1965 [4 Dec., 1964], No. 49373/64. Heading H3B. [Also in Division H1] Information is read out of a circulating current superconducting memory by including a superconducting gate in close proximity to the element and applying an alternating signal thereto. The word organized memory of Fig. 1 has information written in by passing a current along the selected word write line 2, each column representing a word, and then applying along all the bit write lines 4 simultaneously a current when a " 1 " is to be stored. The bit write current drives the associated gates 3 of the superconducting ring elements 3 resistive so that when the currents in the write lines ceases a circulating current is set-up in the ring. In order to read out a selected word the associated word read loop 7 is energized at frequency # 1  from generator 8 and a signal at frequency f 2  is applied to all the bit read lines 5. Each bit read line includes a gate 6 where the line passes close to the element 1 and the magnitude of the current from 8 is adjusted so that while alone it is not sufficient to drive a gate 6 normal, in combination with the flux caused by a circulating current the resultant flux is sufficient to repetitively drive gate 6 into a normal condition at frequency # 1 . Thus, the output from the bit read line will contain derivatives of the frequencies f 1  and f2 and the presence or absence of a signal at the difference frequency at detectors 11 is indicative of a " 1 " or " 0 " stored in element 1. In a second embodiment the storage elements are in the form of rings connected in series with a bit write line and the other conductors including the gate are passed through the centre of the ring, Fig. 2 (not shown). Instead of an electrical signal f 1  radiant heat may be focused on the gates at the frequency f 1  the magnitude of the heat being adjusted so as to be insufficient in itself to drive the gates normal, but sufficient in combination with any persistent current.

[Also in Division F4] In a heat treatment apparatus for a textile web 10, the chamber is subdivided by partitions 2 into zones 5, 6 and a greater suction draft is created in the first inlet zone than in succeeding zone or zones by graduating the fans according to the progression of drying, the sieve drums being equally enveloped by the web. Thus, in zone 5 the fans are small, high pressure fans which run at a greater speed than the succeeding fans associated with the sieve drums 9. Higher temperatures may be maintained in the earlier zones by direct or indirect heaters and curved, perforated plates 13, 14 may be adjustably mounted about the circumference of the sieve drums.
