Title: Improvements in directive antennas
IPC: H01Q19/17
Filed: 1944-08-16
Abstract: 590,557. Aerials ; wave guides; WESTERN ELECTRIC CO., Inc. Aug. 16, 1944. No. 15670. Convention date, Aug. 21, 1943. [Class 40 (v)] A directive transmitting and receiving antenna comprises a concave reflector, the line , focus of which is aligned with a linear slot in a leaky wave guide. As shown, Fig. 1, a transceiver 1 energizes over a concentric line 2, a V leaky wave guide antenna consisting of a stem portion 8 and legs 6, 7 slotted longitudinally at 9. The two slot antennµ 9 transmit horizontally polarized H11 waves as shown by arrows 16, the angle between the legs 6, 7 being so arranged relative to the phase velocity, that maximum action occurs along bisector 10. Triangular metal side plates 11, 12 prevent side radiation and function to transform the two-slot antennae 9 into a wider aperture antenna 13. The antenna of Fig. I is disposed with the longitudinal axis 14 of the aperture antenna 13 aligned with the line focus 24 of a parabolic reflector 28, Fig. 3, having sectoral end shields 26, thereby producing a sharp directive lobe, Fig. 4 (not shown). For lobe sweeping, ; Fig. 5, a wave guide 50 having a longitudinal slot antenna 51 and of length equal to half a wavelength is oscillated by a motor 55 so that the slot antenna 51 moves back and forth 'through the focal line, 24 of the reflector 23. The ends of the guide 50 are closed to render the propagated and reflected waves cophasal and the coaxial line 2 has a rotatable junction 52. Lobe sweeping may alternatively be effected, by maintaining the wave guide antenna 50 stationary and oscillating a two- or four-sided reflector located between the concave reflector and its line focus, Figs. 7, 10 (not shown). A corner reflector may be used. The Specification as ,open to inspection under Sect. 91 also describes an arrangement wherein two V leaky wave guide antennµ similar to those ,of Fig. 3 are disposed side by side, Fig. 5 (Cancelled), the line focus 24 of the reflector 28 being disposed between and parallel to the two apertures 13. A wave guide switch 38 driven by.a. continuously running motor (not shown) alternately switches the transceiver to the two antennµ so that the direction of maximum radiant action is alternatively switched (jumped) between two paths making equal angles with the reflector axis 36. This subject-matter does not appear in the Specification as accepted.

Abstract: 1457652 Packaging films AGFA-GEVAERT 9 April 1974 [23 Oct 1973] 15705/74 Heading B8C [Also in Division G2] A belt-like package 20 made up of interconnected separate packets 23 each containing sheet material such as unexposed X-ray film, comprises a pair of thermoplastic webs sealed together around the periphery of each item of sheet material. One of the webs is formed from a pair of partially overlapping strips 24 and 25, the outer of which (24) has a free edge formed with tab portions 26. The strips are bonded together along a line by a weak weld 27. Lines of weakness are provided around each packet to facilitate its removal from the package, such lines being produced by pressure during welding, by perforations, or by slots. In use, after a packet is removed from the package it is opened merely by grasping the tab portion and pulling. A package may be made by welding the webs to form open packets, retaining the packets open whilst inserting sheet material and finally welding the packets closed.

Title: Improvements in or relating to the manufacture of tobacco compositions
Inventor: RICHARDS GEOFFREY NORMAN
IPC: A24B15/12
Filed: 1962-04-27
Abstract: Tobacco material is subjected to two treatments, (i) a chemical treatment with dilute acid, CO2, or a chelating agent which converts the natural pectate (i.e. the calcium salt) into a more soluble substance, (ii) a pulping treatment in hot water, whereafter the material is formed into a shaped product e.g. sheet, incorporating the soluble substance.  Water extractable salts which affect the strength of the sheet may be removed prior to the chemical treatment, by soaking the tobacco material (e.g. stems) in water to which detergent may be added, removing surplus water, cooking in water and beating to form a pulp.  The methods of chemical treatment include (1) working out undesirable cations with acid (e.g. hydrochloric) and neutralizing the so formed pectic acid with alkali (e.g. sodium hydroxide) to form soluble sodium hydrogen pectate, (2) precipitating calcum carbonate from the calcium pectate by bubbling carbon dioxide through the pulp, (3) producing free pectic acid by adding acid (e.g. hydrochloric or acetic) to the washed stem pulp, (4) converting the calcium pectate to pectic acid by use of a chelating agent e.g. ethylene diamine tetraacetic acid disodium salt.  Descrption of the different methods of treatment is given.

Inventor: COLLIE WILLIAM
IPC: B05C3/10
Filed: 1959-05-12
Abstract: <PICT:0947512/C3/1> Apparatus for dipping articles suspended on a carrier into a bath with a breachable layer on its surface, e.g. flux or tin having a surfacelayer of scum, includes means for moving the article and at least part of its carrier forwardly along the bath and downwards and upwards through the surface layer and for moving the carrier and article backwards while the article is immersed, so that thereafter it is lifted out of the bath through an opening in the surface layer which has been caused by previous movement of the object or carrier.  The apparatus may be combined with a conveyer for carrying the articles through a series of baths.  The required movement may be obtained by suspending the articles 7, through a carrier 6 and brackets 5, from the pivot 4 of an arm 3, which is radial to a wheel 1, the wheel rolling along a track 10 above the surface L of the bath.  The wheel 1 may be toothed, and the track 10 may comprise rack portions, catches or friction washers being provided to maintain the position of the arm 3 when rotation is not required, as when moving between baths, or through washing baths.

Polyhydroxy compounds and mono- and di-carboxylic acids may also be present in the reaction mixture.  The examples disclose the preparation of alkyds from glycidyl esters of branched monocarboxylic acids (C9-C11)and:- (I) pyromellitic acid, glycerol and methylene glycol; (II) and (III) trimellitic anhydride, adipic acid and propylene glycol and (IV) and (V) pyromellitic acid, dipropylene glycol and glycerol.

Title: Organic esters of 2-(2-diethylamino-ethoxy)-ethanol and process for the preparation thereof
IPC: C07D309/08
Filed: 1954-06-02
Abstract: The invention comprises esters of the general formula <FORM:0753779/IV(a)/1> wherein R is 1-phenyl-cyclopentyl, 1-phenyl-cyclohexyl, 4-phenyl-4-tetrahydropyranyl, 1-phenyl-cyclopropyl, diphenylmethyl, phenyl-cyclohexyl - methyl, phenyl - (2 - thenyl)-methyl, phenyl - furfuryl - methyl, or 1-(alpha - cyclohexyl - p - methoxybenzyl) - 4-piperazinyl, and their hydrochlorides and acid citrates; and their preparation by esterification of 2 - (21 - diethylaminoethoxy) - ethanol with either the appropriate carboxylic acid halide RCOHal, with or without the use of a hydrogen chloride acceptor, or the methyl or ethyl ester of the appropriate carboxylic acid RCOOH.  It is stated that other methods of esterification may be used.  Salts are prepared by reacting the esters with either hydrogen chloride or citric acid in a medium such as ether or acetone.  In examples, which describe the preparation of all of the above esters, the first of the above esterification methods is carried out in boiling toluene or boiling pyridine and the second by adding sodium to the reaction components of which the amino alcohol is in excess and distilling off the methanol or ethanol formed together with the excess amino alcohol. The products are useful as spasmolytics. Methyl-phenyl-furfuryl-acetate is obtained from furfuryl chloride and the sodium salt of phenyl acetonitrile followed by saponification of the phenyl-furfuryl-acetonitrile and esterification of the carboxyl group with excess of diazomethane in an ethereal medium.  Ethyl - 1 - (alpha - cyclohexyl - p - methoxybenzyl) - 4 - piperazine - carboxylate is obtained from monocarbethoxy-piperazine and alphacyclohexyl-p-methoxy benzyl chloride.
