Title: Production of porous electrodes
IPC: H01M4/98
Filed: 1962-11-01
Abstract: Single frame porous catalyst electrodes, for use in the electrochemical decomposition of gaseous or liquid fuels in fuel cells, hydrogen separation in electrolysis cells, e.g. from aqueous alkali solutions using nickel electrodes, KC103 electrolysis and in amalgam-hydrogen elements, are produced by mixing, preferably under mechanical pressure, one or more metal powders which are to form the electrode with one or more metal powders which are soluble in alkaline or acidic solution, pressing the powder mixture into shape and then sintering or simultaneously shaping under pressure and sintering, and treating the shaped article with alkaline or acidic solution in which the first metal or metals are insoluble to dissolve out the second metal or metals.  Preferably the powder mixture consists of by weight 30-95% of the first metal or metals and 5-70% of the second metal or metals, and sintering is effected at 350-800 DEG C.  The shaped powder metal, which may be provided with a sheet, sieve or mesh metal backing, may be presintered below the sintering temperature, preferably in a plurality of stages of increasing temperature, prior to sintering.  For example, a porous nickel electrode is made by mixing a powdered mixture of 32% Ni and 68% Al of particle size 10-40 micron in a pressure-mixing device, shaping under pressure, placing the shaped piece on a nickel support in a hydrogen atmosphere and pre-sintering at between 350 and 450  DEG C., and sintering at 460-600  DEG C., prior to treating with KOH solution to which may be added tartaric acid. For alkaline electrolytes, the first metal may be Ni, Cd, Ag, Pt, Ir, Rh and/or Pd, and the second metal Al, Zn, Mg, W, Mo and/or Fe. For acidic or neutral electrolytes the first metal may be Pb, Pd, Pt, Ir, Rh, Ti, Ta and/or Cr, and the second metal Al, Zn, Mg, Ni, Ag, Cu or Fe.

In a photographic transfer process, at least one of the two sheets subsequently pressed together to effect the transfer is wetted with developer liquid on the contact side by a wetted application roller. In the arrangement of Fig. 1, the exposed negative sheet 3<SP>1</SP> enters into the apparatus between guides 3, 4, is passed between rollers 9, 6, where it is wetted on one side only by roller 9 dipping into a bath 7 of developing liquid, and is guided by a wire grid 10 to the nip between pressure rollers 6, 5.

Title: Crop elevators for harvesting machines
IPC: A01D41/12
Filed: 1972-09-20
Abstract: 1400055 Crop elevator SPERRY RAND CORP 20 Sept 1972 [20 Sept 1971] 43490/72 Heading A1F A crop elevator suitable for operation between the header and the threshing device on a combine harvester consists of a housing containing a crop conveyor 64 and two crop transfer beaters 66, 68, the first of which has the additional function of lacerating the crop and also of causing solid debris to be discharged into a stone trap 270. The crop conveyor 64 consists of 3 parallel chains trained around a drum 70 and sprockets 72 and carrying transverse slats. The conveyor causes the crop to move along the ramp type feed plate 126, the space above which is variable, to accommodate varying crop thickness firstly by virtue of the spring loaded arms 98 supporting a drum 70 and secondly by means of the adjustable housings 104 carrying the sprocket shaft. The first beater 66 is built from four blades 150, 152, 154, 156 which serve to convey the crop and also to drive stones and the like along a tangential path into the stone trap 270. The axis of the beater is positioned above the projected path of the feed plate to assist the process. The first beater 66 carries a number of knives 168, while spaced between them are fixed knives all of which serve to lacerate the crop to ease the stone separation. The stone trap 270 has a hinge 276 along one side and a catch consisting of a spring rod 284 along the other. The second beater 68 is driven at a higher peripheral speed than the first beater 66 in order to even out and thin the crop mat. Similarly the peripheral speed of the first beater 68 is greater than the crop conveyor speed. The shafts are chain driven with idlers for adjustment purposes. When used with a double rotor axial flow combine, the fixed knives carried by the floor of the housing include a pair which separate the crop mat along its centre line. An alternative arrangement for either or both the beaters Fig. 9 (not shown) whereby the drive shaft 302 carries a number of flanged discs 304 which in turn support a number of transverse angle-iron slats 306. The ends 308 are formed so as to lead the remainder of the blade while at the centre of each is formed at V 312 pointing (forward) with respect to the direction of rotation. This special shaping ensures that the crop does not spread sideways and also that separation takes place along the centre line of the crop.

The polyester (A) may be polyethylene terephthalate polybutylene terephthalate or polyethylene 2,6-naphthalate and the polyester (B) may be a block copolyester derived from terephthalic acid, isophthalic acid, the sodium salt of 5- sulpho-1,3-isophththalic acid, 1,4-butanediol and polyethylene glycol, or a copolyester derived from terephthalic acid, isophthalic acid, and 1,4-butane diol and/or ethylene glycol. The layers which may also contain stabilizers, ultraviolet ray absorbers, antioxidants, plasticizers, fillers, pigments, crystallizing agents, lubricants, and antistatic agents, may be in immediate contact or may be provided between the layers with anchor coatings, adhesive agents or polymeric layers, e.g. polyvinylidene chloride or polyvinyl alcohol. The preformed layers may be bonded together to produce the laminate or the laminate may be produced by coextrusion of the layers. The first layer may be stretched longitudinally and after bonding together of the layers the resulting laminate may be stretched transversely and then heat-set.

Abstract: 1,248,989. Parallel multiplier. HUGHES AIRCRAFT CO. 10 Sept., 1969 [26 Sept., 1968], No. 44768/69. Heading G4A. A digital electric multiplier comprises a plurality of multiplier circuits MB1-MB4, each connected to receive an equal lengthed group of bits from both the multiplier and the multiplicand, and capable of producing a partial product; and adder means for combining the partial products into a final product. To multiply an eight bit multiplicand D 1 -D 8  by an eight bit multiplier M 1 -M 8  each identical circuit MB 1 -MB 4  is simultaneously supplied with a unique combination of a group of four adjacent bits from the multiplier and four adjacent bits from the multiplicand, each circuit produces a partial product, and the partial products are summed in an adder 22. The sign of the product is produced in unit 89 and a 17 bit product (16 bits + sign) formed in unit 90. Each circuit comprises a plurality of full adders (Fig. 4, not shown) which add columns of ANDed bits from a matrix to produce the partial products. The partial products can be produced by full adders alone (Fig. 7, not shown). The four partial products are fed simultaneously to the adder 22 which comprises full adder circuits and which employs carry look ahead in some of its stages (Fig. 5, not shown). A further number can be added to the product calculated using further adders. Each full adder circuit (Fig. 6, not shown) can be formed as a large scale integrated circuit. Any length of operand can be used and an application to linear digital filtering is described (Fig. 10, not shown).
