Abstract: 1,228,808. Haymaking machines. C. VAN DER LELY N.V. 12 July, 1968 [17 July, 1967], No. 33446/68. Heading A1F. An implement for working ground-lying crops comprises a mobile frame 1, at least one tined rake member 4, 5 mounted on the frame so as to be rotatable about an upright axis 15 (Fig. 2), and a guide member 12 which can occupy a position in which it windrows the crop. A pair of tines is mounted on a bar which is pivotably mounted in a sleeve at the end of spoke 13 of which there are eight per rake member, and can be held in any one of at least two positions by a spring loaded locking pin whose enlarged head 23 fits into one of holes 19 in plate 18. The pin can be withdrawn by handle 26 (Fig. 1). Variations of this adjusting mechanism are: (i) a forked bracket at the end of spoke 13 containing a pivotable bar and similar locking means to the above (Fig. 6, not shown); (ii) an extension of the coiled part 28 of the tines to provide a handle; the coiled part being pivotable about the end of spoke 13 which is bent at 90 degrees to the main portion of the spoke, and the handle being locked in positions by a grooved plate on the spoke (Fig. 8, not shown); (iii) a forked bracket as (i) pivotably connected to another forked bracket on which the tines are mounted, this second bracket being locked in position by a method similar to (i) above (Figs. 10, 11, 12, not shown); (iv) a block on which the tines are mounted being pivotably mounted between the arms of a forked bracket as (i) above, the block being locked in position by a pin engaging one of a number of holes in the block. The tine mounting member may be connected by a rod to an annular disc around the hub of the rake member so that by rotating the disc the position of all the tines on all the spokes 13 can be changed simultaneously. If only one rake member is used the guide member comprises a plate supported on an arm extending, and adjustable, laterally of the direction of movement of the machine. This guide member is capable of swinging over on to itself (towards the centre of the rake member) as is the original guide member, when not in use. The implement is connected to a tractor by drawbar 7 whose angular setting is adjusted by cranked spindle 8 and the gearbox drive is connected to the tractor p.t.o. by splined shaft 10. The implement is supported on wheels 6 or skids.

Abstract: 1,231,507. Polyvinylidene fluoride coatings. FORMICA INTERNATIONAL Ltd. 30 Dec., 1969 [6 Jan., 1969], No. 826/69. Heading B2E. A process for forming a coating of vinylidene fluoride polymer on a porous substrate initially containing moisture comprises applying a priming layer in at least one surface of the substrate, applying a liquid dispersion of finely divided particles of the polymer to the priming layer and exposing the so-treated substrate to microwave radiation so as to cause the particles of that polymer to coalesce and form a coherent layer firmly bonded to the substrate. The dispersion may be in a polar organic liquid such as a high boiling point alcohol, ester or ketone. A preferred solvent is isophorone. A dispersing agent such as an acrylic resin may be present as well as inorganic pigments such as titanium dioxide. The substrate may be a cellulosic material such as wood which may be in the form of chipboard, plywood and blockboard, hardboard, fibre board, or paper, or of inorganic mateials such as asbestos, vermiculite and perlite. The priming agent preferably contains a resin of the same or similar type to that used as the dispersing agent in vinylidene fluoride polymer dispersion. The moisture content of the substrate should be adjusted to 3-16% before application of the coatings.

Abstract: 1,239,483. Gating circuits. AMERICAN STANDARD Inc. 16 July, 1968 [17 July, 1967], No. 33883/68. Heading H3T. A filter selector circuit has a plurality of channels A, B, C with respective inputs connected to band pass filters 5, A, B, C having successive bandwidths with adjacent bandwidths having overlapping portions (Fig. 5, not shown), the channels are coupled together such that an output signal will appear at the output of only that channel which is associated with that one of the filters which passes the greatest magnitude signal and the channels have means Q3, CR2, CR3 providing a hysteresis effect which prevents the circuit hunting back and forth between channels when two of the filters with adjacent bandwidths pass substantially equal magnitude signals in the overlapping portions of their bandwidths. Inputs of different frequencies are fed from the outputs A, B, C of band pass filters (Fig. 4, not shown), to an input transistor Q1 of each channel. The outputs from the transistors Q1 are split into two paths X and Y, one to a keying transistor Q2 and the other to an output transistor Q5 via diodes CR4. Assume that the input signal of the greatest magnitude occurs to channel B. The rectified and smoothed output from CRIB and C2B exceeds the bias necessary to turn transistor Q2B ON. This turns transistor Q3B ON and the output voltage across R8B and diodes CR2B and CR3B increases to cause a regenerative action to occur turning ON transistors Q2B and Q3B until Q3B saturates. The output voltage of Q3B biases transistor Q4B OFF and allows diode CR4B to conduct and gate the input signal to channel B to output transistor Q5. The increased current through the emitter resistor R15 biases transistors Q2A and Q2C to cut off so that keying transistors Q3A and Q3C are OFF and transistors Q4A and Q4C are saturated ON. This back biases the diodes CR4A and CR4C so that no signal on channels A and C reach the output transistor Q5. The circuit may be fed via an automatic gain controlled amplifier (4, Fig. 4, not shown) and the band pass filters (A, B, n) so as to determine when an input sinusoidal signal (Fig. 1, not shown), such as from a flow meter, passes an upper and lower limit (c, d). The frequency of the input signal is then determined by feeding the output of the circuit of Fig. 6 to a trigger circuit (7) and counter (8) so as to determine the flow rate.

Abstract: 1,257,106. Vinyl chloride polymer emulsions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 April, 1970 [23 April, 1969], No. 20805/69. Heading C3P.  The stability of vinyl chloride polymer emulsions prepared by polymerization at below 0‹ C. in an aqueous medium containing an antifreeze, is improved by reducing the concentration of anti-freeze in the emulsion. Reduction may be effected by dialysis through a membrane permeable to the anti-freeze and water, e.g. of regenerated cellulose. Alternatively the reduction may be effected by evaporation. The concentration of anti-freeze may be reduced to below 15%, preferably below 5% by weight of the emulsion to provide emulsions suitable for fibre-forming. Examples describe the dialysis of emulsions prepared by polymerizing vinyl chloride in aqueous media comprising ethylene glycol with or without methanol, in the presence of sodium or ammonium nonylphenyl polyoxyethylene sulphates, catalysts comprising ammonium persulphate, ferrous sulphate and optionally ascorbic acid, and sodium phosphate buffer.

Profiled blanks are bent to a configuration consisting of successive portions of curves of different radii of curvature by placing a blank on a bending die, shaping the portions of large radius by means of rolls moving over the surface of the blank on the die and then shaping the portions of small radius by maintaining the rolls stationary and pivoting the die so that the rolls wrap the blank around a part of the die having the small radius. An apparatus for carrying out the method comprises a frame 1 in which is pivoted at 2 an arm 3 carrying rolls 19 in a housing 12 mounted at the end of a cylinder and piston assembly 7, 8, 9 which provides an adjustable force on the blank. A die 30 is mounted on bolsters 29 pivoted about a pin 28, and means is provided for moving the arm 3 from the vertical to an inclined position (shown by chain dotted lines) and for moving the die 30 about pivot pin 28. The bolsters are held in position by blocks (41) Fig. 3 (not shown) during the bending of the blank to a large radius after which they are withdrawn into passages 39 which allows the pivoting of the die about pin 28. The blanks are held on the die by a clamp 38 and one half of a blank is shaped at a time.
