Title: Improvements in producing textile materials containing synthetic condensation products
IPC: D06M15/423
Filed: 1936-12-09
Abstract: Textile materials rendered crease-resistant, stiffened or delustred by the presence of synthetic condensation products have their wearing properties improved by treating with natural or artificial rubber latex including rubber-like polymerized hydrocarbon before, during, or after the synthetic condensation product treatment.  Urea-aldehyde resins are preferably employed. In examples, (1) a urea-formaldehyde precondensate is mixed with natural rubber latex and triammonium phosphate as a potentially-acid catalyst; textile material is impregnated with the mixture, squeezed, dried and heated with or without steam to 120-130 DEG  C. for 2-3 mins.; the product is crease- and wear-resisting: (2) a urea-formaldehyde precondensate is mixed with natural latex, tartaric acid as catalyst, and a sulphonated fatty alcohol sodium salt as a protective agent to prevent coagulation of the latex; textile material is impregnated, dried and heated in hot air or over heated cylinders at 120-170 DEG C.: (3) as in example 2, except that chlorinated rubber dissolved in benzene is used instead of latex, and emulsified with the protective agent.  Other examples describe the production (a) stiffened fabrics and (b) of a delustred fabric using a non-resinous urea-formaldehyde condensation product followed by treatment with a latex dispersion. Specifications 291,473, 291,474, 304,900, [all in Class 42 (i)], 413,328, 424,535, 437,361, 449,243, and 467,480 are referred to.

Title: A method of and an apparatus for testing paper and like pulp
IPC: D21G9/00
Filed: 1931-12-10
Abstract: 376,176. Testing paper and like pulp. ABRAHAMSEN, B., Lysaker, near Oslo, Norway. Dec. 10, 1931, No. 34282. [Class 96.] The rate of drainage of water through fibrous pulp on a wire gauze 2 is determined, with a homogeneous pulp suspension in water under a constant or a decreasing water pressure, a layer of pulp being deposited on the gauze in proportion to the water drained, by measurement of the times required to draw off two consecutive and equal volumes of water, or of the volumes drawn off during two consecutive and equal times ; such measurements being stated to allow determination of the degree of grinding of the pulp without knowing the concentration of the suspension. Pulp is diluted and a measured volume poured through a funnel 6 into a flask C which is tilted over into a funnel A and placed on the top ribs of a funnel B, the arrangement providing a constant head at the level 1, air bubbles entering the flask C maintaining homogeneity, and the ribs &c. forming channels preventing eddies &c. The water drains through the gauze 2 which may be 10 sq. cms. in area and 20 cms. from the level 1, through a funnel 3 and along a trough 4, until a flask 12 is filled to a mark, e.g. at 200c. cms., when the trough is tilted to direct the water into a second flask 12 which is filled to the same volume, the two times for filling being noted. There may be a releasable closure mechanism in the funnel 6 ; the flasks 12 may be substituted by a counterbalanced weighing system, the trough 4 may be dispensed with and a flask used which may be divided into two parts each having a volume mark. There may be ribs and notches in the funnel 6 and injector effects may be avoided in the funnel 3 by holes near the gauze 2.

Class 40(7) A wide-band aerial comprises a dipole constructed as two mechanically rigid grids, cages, or lattices each rigidly supported at a voltage node. The radiating elements may be constructed in any of a variety of forms, for example, six metal tubes 1 may be arranged in a hexagon to form a cage and the tubes extended to meet at an apex to which the feeder is connected. The elements themselves may be streamlined or they may be wholly or partially enclosed in a streamlined insulating cover. They are rigidly supported either by attaching them directly to the mast (Fig. 2) or through a short off-setting arm (Fig. 4). Two elements, each supported at voltage nodes, can be arranged vertically on off-set arms from the same mast to form a vertical dipole (Fig. 4). The elements when horizontal and of lattice form may be constructed as cantilevers extending out from the structure of the supports, Figs. 5 and 6 (not shown). Arrays of wide-band aerials according to the invention may be mounted on each side of an extensive support framework serving both as rigid support and reflector wall for the arrays. Adjustment of the radiating or receiving direction can be achieved by mounting the support framework on a central pivot point and spaced rollers running on a circular track (Fig. 7, not shown).

Title: Production of heavy alkylate
Inventor: OLDHAM WILFRED JOHN
IPC: C07C15/107
Filed: 1965-08-12
Abstract: Heavy alkylate (an alkylation residue of higher boiling point than detergent alkylate) is produced in increased yield by pretreating at least part (e.g. up to 50%) of a feedstock comprising one or more C8-16 olefins with liquid anhydrous HF, bringing the pretreated feedstock into contact with benzene or naphthalene in the presence of an alkylation catalyst, e.g. AlCl3 or HF, and separating the heavy alkylate from the product.  The pretreatment of the feedstock may be carried in a separate vessel from the alkylation, or by feeding the feedstock and HF into the alkylation vessel through a common pipe in which the pretreatment takes place, or by merely feeding the feedstock and benzene or naphthalene into different parts of an alkylation vessel already containing HF so that the olefin is contacted with HF before meeting the benzene or naphthalene.  The product is mainly mono-alkylate, usually with some di-alkylate.
