Title: Improvements in the treatment of textile fabrics to reduce shrinking thereof
IPC: D06M15/423
Filed: 1940-07-18
Abstract: 542,233. Treating textiles. ARNOLD PRINT WORKS. July 18, 1940, No. 11835. Convention date, Aug. 30, 1939. [Class 15 (ii)] [Also in Group VIII] The shrinkage in textile fabrics is reduced by treating the fabric with a solution of ingredients for the formation of a synthetic resin, heating to insolubilize the resin, moistening the fabric containing the insoluble resin, mechanically reducing its length while in the moistened condition and then drying the moist fabric while mechanically holding it at the reduced length : the fabric is preferably padded with a solution forming a ureaformaldehyde resin and then preliminarily dried at a temperature below the insolubilizing temperature before insolubilizing the resin by heat. The fabric is drawn from a creel, passed between a pair of rollers, the lower of which is immersed in the resin solution, and, with the excess solution squeezed out, is passed over and between guide rolls to a drying tenter where the fabric is preliminarily dried at a temperature of 190‹-240‹F. The dried fabric then passes into a curing box maintained at a temperature of 300‹-320‹ F. where the resin is insolubilized and, after leaving the box, the fabric is passed through an oscillating folder frame into a creel ; after curing the fabric may be given an open soaping wash to remove any residual resin. The fabric is then given the supplementary treatment further to reduce the shrinkage, being drawn from the creel 36, over and between rollers 37 ... 41, over an open tenter 42 and guide rollers 43, 44, 45 to a box 46, where its accumulates in folds and from which it passes over and between rollers 47 . . . 53 to a moistening chamber 54 supplied with a hot water spray 56 ; the rollers 52, 53 may supply water to the fabric. The moistened fabric then passes through guide rollers 57 ... 60 to the endless blanket 61 of a Palmer finishing machine having a large steam-heated roller 63 where the length of the fabric is slightly reduced and the fabric dried and finished. The resin solution may comprise a catalyst and a wetting agent.

IPC: H03B5/30
Filed: 1971-04-28
Abstract: 1306209 Electronic clocks and watches EBAUCHES SA 28 April 1971 [8 May 1970] 11853/71 Heading G3T Oscillation of a balance wheel 1 carrying a magnet 2 is maintained by a circuit as shown wherein a coil 3 acts both as a pick-up and as a drive coil. The operation of the circuit is not described except for the feature characterized by the provision of a diode D to prevent saturation of driving transistor T 1 . When the voltage across diode D reaches the diode threshold value, the potential at point A follows the collector voltage V c  of T 1 . Since the diode threshold voltage and the base/emitter voltage of T 1  are substantially constant the base current of T 1  decreases with V c  so that an equilibrium condition is established before saturation of T 1  occurs.

Title: Insecticides
IPC: A01N63/40
Filed: 1970-03-16
Abstract: 1300447 Replicating insect viruses McLAUGHLIN GORMLEY KING CO 16 March 1970 [17 March 1969] 12573/70 Heading C6F [Also in Division A5] In the production of an insecticidal product, an insect infective virus is inoculated into a culture comprising cells or cell material of a host micro-organism, such cells or cell material being capable of further metabolism and being chosen to support replication of the virus, and the virus is replicated in the culture. Any species of yeasts, bacteria, mycobacteria, fungi, algae, protozoa or like which may be readily grown in the laboratory in a synthetic or semi-synthetic medium under reasonable conditions can be considered for replication trials. Typically, the virus is one of the infective viruses for insects of the order Lepidoptera (specified) and the micro-organism is a fungus of the family Saccharomycetaceae or a bacterium of the orders Actimomycetales, Eubacteriales and Pseudomenadales. The micro-organism is first activated in or on a nutrient medium until about completion of its logarithmic growth phase, thereafter the cell walls of the micro-organism are at least partially disrupted (while still maintaining a viable culture of host cells) by specified chemical, mechanical, physical or enzymatic means, but preferably by use of a so-called transformation medium of high osmotic pressure, to permit or to improve infection by the virus of the cytoplasm and /or cytoplasmic membrane of the cells of the micro-organism, and replication of the virus (after inoculation) may be effected in the transformation medium. This consists of 5-20% by weight of sucrose and small amounts of magnesium sulphate, sodium acetate and tryptone. The resulting product may be concentrated or dried for use as a viral insecticide. In commercial use the product may be diluted with a suitable carrier or diluent such as water or other liquid, bentonite, clay or talc, and may be mixed with conventional sticking agents such as carboxymethyl cellulose, stick liquor, gums or acrylic resins. These additives may be incorporated with the virus host-cell mixture prior to concentration and drying. An example is directed to the replication of fall armyworm polyhedrosis virus on a strain of Saccharamyces cerevisiae isolated from the gut of a corn earworm larva. The product was found to be capable of establishing viral infections in fall armyworm, southern armyworm and corn earworm insects found in crops. Other examples relate to the cultivation of viruses from these insects upon Bacillus thuringiensis and Bacillus subtilis.

IPC: C09C1/06
Abstract: 126,626. Desachy, P. Oct. 19, 1917, [Convention date]. Pigments.-A mixture of barium sulphate and zinc sulphide is prepared by mixing together a. solution of zinc sulphate and a solution of an alkali or such salt of an alkali metal as will produce an insoluble zinc salt, such as a sulphite, and then acting upon the resulting zinc hydroxide or zinc sulphite concurrently with its formation by a solution of barium sulphide, from which a portion of the barium has been previously separated in the form of carbonate by treatment with carbonic acid. The zinc sulphate and alkali or sulphite solutions are brought to boiling-point in the tanks a and b respectively, and discharged into the mixing-tank m with continued heating. As soon as precipitation begins, the barium sulphide solution is run in from the tank c, tests being made on the mixed liquor with lead carbonate paper to avoid employing excess of sulphide.

Means for mounting bulky agricultural apparatus such as root-crop harvesters, combines, and hay-loaders upon a tractor comprise a pair of main mountings spaced apart one on each side of one of the tractor rear-wheels and a further mounting 17, 17A at a forward location, each mounting comprising inter-engageable parts on the tractor and apparatus respectively and the means includes temporary supports 18, 19 for the apparatus enabling the tractor to be backed under it. The apparatus shown is a combine-harvester having main-beams 10 carrying downwardly-extending legs 20, 23 on which are formed the main mountings. The inner main mounting, Fig. 7, comprises a casting 21 welded to the end of the leg 20 and having an arcuate bearing surface 21B which engages a complementary arcuate surface 22C on the casting 22 which is bolted to the tractor axle 5. The sides of castings adjacent to the bearing surfaces are bevelled to assist centring. The two castings are maintained engaged by an eccentric pin 22I inserted through slots 21C, 22F in the castings, the slot 22F being arcuate about an offset centre relatively to the bearing surfaces, to cause locking of the parts as the bearing surfaces are engaged. The outer mounting, Fig. 10, comprises a conical extension 26B co-axially bolted on the wheel-hub 8 and terminating in ball-races 25E which support a part 25 to which a casting 24 on the end of the leg 23 is clamped. The front mounting comprises projections 17, 17A on the tractor and apparatus which can be held engaged by the insertion of a pin through aligned lugs. The temporary supports comprise retractable jacks 19 at the rear and a lockable sprag 18 pivoted on a cross-bar 18C on the apparatus. With the apparatus supported as in Fig. 1, the tractor 2 is backed underneath and the main mountings are engaged. The jacks then tilt the apparatus forwardly about the bearing surfaces of the main mountings to align and engage the front mounting parts 17, 17A. On retraction of the jacks and sprag the apparatus tends to swing backwardly but the attachment of the front dividers and mower-bar brings the centre of gravity of the combination back within the wheel-base. Specifications 541,220 [Group XXXI] and 782,492 are referred to.
