Title: Improvements in or connected with the framework of looms for weaving
IPC: D03D49/02
Filed: 1929-04-18
Abstract: 332,281. Wood, A. E., (Crompton & Knowles Loom Works), April 18, 1929. Framework. -Each side frame 10, Fig. 4, is substantially flat on its outer surface, but has projections of sufficient depth to permit them to be ground &c. to an exact plane to receive various loom attachments such, for example, as the bearing blocks 70 of the pricking shafts. The inner faces have deep strengthening ribs 50 adjacent ones of which are bridged across at certain parts, the faces of the bridges 60 being aligned with the tops of the ribs. Bolts 63 with annular reinforcements 65 extend through these bridges 60 and through the flanges 64 of cross girts 11, 12 which are thus connected to the side frames. Arrangements are described for securing the loom arch adjustably to the loom sides and also for attaching the weft carrier magazine. The Specification describes a. drop box loom having picking mechanism, which is stated to be of known type. The various loom attachments are designed so that they can mainly be bolted to the loom sides. Breast beams.-The wooden breast beam is bolted to the end frames and is braced by pockets formed by the ribs. Securing looms to floors.-Foot plates screwed to lateral extensions on the feet of the side frames are secured to the floor by lag screws.

Title: Compositions for increasing efficiency of animal nurture
IPC: A23K20/195
Filed: 1958-04-16
Abstract: Kanamycin, the antibiotic substances isolated from the fermentation broth of S. Kanamyceticus, is employed in a feed supplement containing a non-toxic diluent e.g. calcium carbonate and steamed bone meal, fuller's earth, oyster-shell meal, carboxymethylcellulose, and others.  The proportion of kanamycin in an animal feed may range from 1 to 400 grams per ton of feed; alternatively, a feed supplement may be prepared which upon dilution with water provides a concentration of 0,05 to 2,0 grams kanamycin per gallon.  Examples relate to kanamycin sulphate.  Reference is made to J. Amer. Chem. Soc. 80 (1958) and to The Journal of Antibiotics (Japan) (1957) in regard to the nature and properties of kanamycin compounds.

Abstract: 1285572 Evaporators; heat pump type PARKSON INDUSTRIAL EQUIPMENT CO Ltd 12 March 1970 [12 March 1969] 13126/69 Addition to 1202268 Heading B1B Partial evaporation of a liquor is effected by contacting compressed refrigerant vapour, supplied by compressor 10, with an auxiliary liquid (e.g. water or mineral oil) in heat-exchanger 1 wherein the refrigerant vapour is condensed and the auxiliary liquid is heated, passing the hot auxiliary material by means of pump 4 through the shell of heat exchanger 2, supplying the liquor to be evaporated by pump 5 to the tubes of heat-exchanger 2, leading the heated liquor to separator 6 where vapour is separated, and withdrawing concentrated liquor from separator 6 by pump 7. The vapour from separator 6 is condensed by heat-exchange with liquid refrigerant in heatexchanger 3; some of the refrigerant vaporizes, and the refrigerant vapour is drawn from separator 23 via valve 50 into compressor 10. Residual process vapour is passed to watercooled condenser 22. Liquid refrigerant, withdrawn from heat-exchanger 1, is passed via heat-exchanger 51 into the tubes of heat-exchanger 3. Part of the liquid-refrigerant from separator 23 is passed via heat-exchanger 51 to heat-exchanger 1. Auxiliary liquid returns from heat exchanger 2 to heat exchanger 1. Heat-exchanger 2 is made of stainless steel, but heat-exchanger 1 may be of inexpensive carbon steel. In a modified plant, the compressed refrigerant vapour leaving compressor 10 is supplied, not to heat-exchanger 1, but to the shell of heat-exchanger 2, where again it comes into contact with the auxiliary liquid. The liquor leaving heat-exchanger 2 may be submitted to one or more flash evaporation stages. The compressor may be driven by a Diesel engine or a gas turbine, the waste heat of the engine or turbine being utilised for heating the auxiliary liquid before and/or after it flows through the heat-exchanger 1. An emulsion of liquid refrigerant in water containing a suitable emulsifying agent may be used instead of only liquid refrigerant.

[Also in Division B2] A machine for converting to pulp paper of any kind including paperboards includes a tank beneath which are located two discharge chambers separated from the tank and from each other by perforated walls, there being mounted within the tank above one perforated wall a set of vanes on a shaft that also carries a second set of vanes rotatable in the upper discharge chamber. The vanes of the first set 7 are so rotated and shaped as to drive pulp liquor towards stationary vanes 24 that divert the liquor back towards the centre of the tank. The vanes 12 of the second set have a suction effect tending to draw liquor through the perforated wall 9, holes of which are tapered from inlet to exit ends and have sharp cutting entrance edges. The vanes 12 also act to scrape pulp from the bottom of the wall 9 as well as serving as a pump producing a head high enough to force the pulp to a greater height than the tank and to convey it to the next treatment machine. The lower surfaces of the vanes of the first set 7 are provided with rims along their leading lower surfaces to co-operate with the perforated wall 9 to chop and pulp the material. The shaft 6 carrying the two sets of vanes is mounted in a manner permitting vertical adjustment to compensate for wear of the rims. Valves 18, 19 are provided in ducts 16, 17 from which pulped material is discharged from chambers 11, 14 according to which valve is open, the chamber 14 only being used if a finer pulp is required. One or more sedimentation chambers 20 may be provided in which heavier impurities may collect. Heavy impurities are also collected in a cup 33 connected directly to the bottom of the tank.
