Patent GB-643935-A (GB)
Title: Improvements in or relating to high-frequency coils
IPC: H01F21/06
Filed: 1948-05-27
Abstract: 643,935. Transformers and inductances. PHILIPS ELECTRICAL, Ltd. May 27, 1948, No. 14343. Convention date, May 30, 1947. [Class 38 (ii)] In a high-frequency inductance or transformer a winding surrounds a cylindrical ferromagnetic core in an axially disposed hole in which moves a ferromagnetic plunger, the arrangement being such that as the plunger moves out of the hole the inductance of the winding increases. The core must not project from the winding by a distance more than half the core diameter. The result is obtained by making at least the core from a material, e.g. a ceramic such as a ferrite, having a permeability not less than 100, .so that the plunger emerging into a region of fairly high flux density reduces the reluctance of the flux path as a whole more than the space created inside the core increases it. Two windings variably coupled by a movable magnetic rod 27, preferably of ferrite, are mounted in housings 11, 11<SP>1</SP> moulded in a carrier member 19 which divides screening box 23 into two divisions which house respectively the leads to the two coils. Each winding 1 is mounted on a cylindrical core 7 in which moves a plunger 9 mounted on and moved by a non- magnetic screw 15. During manufacture the winding 1 is wound centrally on core 7 and after impregnation with wax the core is pushed through until one end is flush with one face of the winding. Specifications 433,366, [Group XXXVI], 629,946 and 637,099 are referred to.

Title: Expanded solid corn syrup products
IPC: C13K1/00
Filed: 1943-09-03
Abstract: 577,994. Evaporating corn syrup. CLEVELAND, F. J. (Granular Foods, Inc.) Sept. 3, 1943, No. 14451. [Class 32] [Also in Group VI] Dried corn syrup products having a moisture content of less than 2 per cent. and suitable for use as food products, caramel colouring and for admixture with fats, peanuts, coconut, soya bean, pecan and walnut flours and chocolate are obtained by heating liquid corn syrup under vacuum of not more than one and a half inches of mercury so that the syrup froths and a dried cellular product is obtained. With a corn syrup having a dextrose equivalent up to 42 a porous spongy friable cellular mass is obtained while when the dextrose equivalent is about 55 a hard cellular product is obtained which may be ground to give a product similar to granulated sugar. The drying is carried out in shallow trays 16, 17 supported on hollow shelves heated by hot fluids fed through pipes 13, 14 the trays being superposed in an evacuated chamber 10. A product suitable as a caramel colouring is obtained by subjecting corn sugar burnt in presence of a catalyst, e.g., ammonia to the above treatment.

Patent GB-1099184-A (GB)
Title: Polyesteramides
Inventor: GOODMAN ISAAC
IPC: C08G69/44
Filed: 1965-04-06
Abstract: The invention comprises crystalline polyesteramides of m.p above 52 DEG  C. containing repeating units of formulae -O(CH2)5CO- and -NHRCO-, where R is an organic radical, the 2 valencies of which are on different carbon atoms. 90-100% of the repeating units are of one of these formulae and there are 1-400 amide units for every ester unit.  R- may be (a) a hydrocarbon radical, e.g. a C3- 20 polymethylen radical, (b) a radical of formula -X(ZY)m-, where X and Y are hydrocarbon radicals, Z is -O- or hydrocarbon-substituted imino and m is an integer or (c) a derivative of (a) or (b) in which a carbon bonded hydrogen atom is replaced by a halogen atom or a hydrocarbon-oxy radical.  The polymers may be derived from polyamide-forming monomers, e.g. lactams or amino-acids or N-acyl derivatives or esters thereof, and ester-forming monomers, e.g. e -caprolactone, e -hydroxy-caproic acid, its acetate or benzoate or its C1- 6 alkyl ester. Amide-forming monomers specified include e -caprolactam, 11-aminoundecanoic acid and e -amino-caproic acid. Where the amide-forming monomer is a lactam, the polymerization may be catalyzed by an anionic catalyst, e.g. an alkali metal such as Na or its oxide, hydroxide, carbonate, alkoxide or alkyl.  In this case a lactone may be added in portions to the lactam during polymerization.  If the amide-forming monomer is not a lactam the polymerization may be acid catalysed.  Acids specified are sulphuric, phosphoric and p-toluene sulphonic.  In either case the temperature may be 100-260 DEG  C. and a reduced pressure or mobile inert gas atmosphere may be used. Hydroxy-acids other than hydroxycaproic acid, monohydric alcohols, mono-primary and secondary amines, monocarboxylic acids and cross-linking agents may be present. Before making the products into fibres, films, adhesives, coatings or moulded articles, thermo- and photostabilizers, lubricants, mould-release agents, pigments, dyes, fillers, plasticizers, and other natural or synthetic polymers may be added. In Example (3) a product of anionic polymerization is treated with HCl to neutralize the catalyst.  In other examples aromatic hydrocarbons are used to extract low M.W. residues from the products.

Title: Improvements in or relating to the manufacture of woven multi-ply narrow fabrics
Inventor: THORP ERIC
IPC: D03D3/00
Filed: 1949-06-01
Abstract: Woven multiply narrow fabrics having one or more main webs with interwoven formations, such as cross-members or pockets, at predetermined pitch or spacing are wetted with an aqueous solution of a thermosetting synthetic resin, e.g. a ureaformaldehyde resin, and then, while under tension and held to p  gauge with reference to the interwoven formations, are dried by the application of sufficient heat to insolubilize the resin. The treatment ensures a greater accuracy of gauge of the interwoven formations than is obtainable from the loom and serves to control the degree of stiffness imparted to the fabric.  The fabric may be dyed prior to the treatment. Drying may be effected by infra-red radiation.

Filed: 1916-10-25
Abstract: 110,592. Coulson, W. T. Oct. 25, 1916. Lamp signals.-In electric-lamp signalling apparatus, the signalling-key can be separated from the rest of the apparatus whilst maintaining the electrical connexion by means of a flexible lead so that whether the parts are assembled cr dissembled, the signalling-apparatus serves its purpose. The permanent switch of the apparatus is arranged to be inoperative when the signalling- key and the lamp bulb are connected by a flexible lead only. Fig. 4 shows a head or belt battery lamp in which the removable cover containing the signalling-key is connected with the rest of the lamp by a flexible lead arranged in the top part of the lamp case when the cover is in place. The spring arm T of the switch is mounted on a fibre base M, and is operated by the finger tips inserted through a hole covered with a diaphragm N of india-rubber, thin metal, &c., or by a button with a stem working in the cover. Insulating paper fibre and a distance piece are inserted between the cover and the spring arm T. The wires of the flexible lead are connected to the fibre base M, and pass respectively through two holes in the base and thence pass through a third hole between the other two to prevent any strain on the connexions with the terminals in the fibre base. The lamp can also be lighted by moving a permanent switch P on the cover so as to conr,ect the end of the switch arm T through the cover with the body of the lamp case. This circuit is broken when the cover is removed. In a modification, the flexible lead is connected to the main part of the apparatus by a plug on removing the signalling-key, and a small lever is pushed aside when inserting the plug, thereby interrupting the circuit through the permanent switch.
