Abstract: 760,850. Ventilating. STONE & CO. (DEPTFORD), Ltd., J. June 8, 1955 [June 9, 1954], No. 16947/54. Class 137 [Also in Group XI] An air diffusing arrangement for vehicles comprises a main duct 1 of inverted channel section with lower flanges 2 fitted to a longitudinal opening in the ceiling 3 e.g. of a railway vehicle, the duct for communication with a supply of fresh, or conditioned air, projecting upwardly into a space 4 between the ceiling 3 and a roof, not shown, and a housing 5 which is disposed within the main duct and has a ridged top to provide air passages 6 on each side which are masked from below by the side wings 25 of an ornamental deflector 21 screwed into the bottom of the housing 5 and forming two lateral air discharge ducts 26. A series of longitudinally spaced holes 8, formed in the top 7 of the duct 1 for admitting air from the space 4, are regulated by a sliding panel 9 having correspondingly spaced holes 10 and mounted on the top 7. The panel 9 is adjusted by a screw-and-nut. device 11 accommodated in the housing 5 and comprising a screwthreaded rod 12 rotatably mounted in brackets 13 in the housing 5, a knurled knob 14 fast on the rod 12, and a nut 15 which is movable axially along the rod, but is non-rotatable. The nut 15 is connected to the panel 9 by wings 16 whose limbs pass through longitudinal slots in the sides of the housing 5 and through one of the holes 8 in the top 7 of the duct 1 for connection by nuts 18 to the sliding panel 9. Guidance for the panel 9 is provided by studs 19 which are fixed to the top of the duct and engage in longitudinal slots in the panel 9. A hand hole, with a removable cover 24, in a flat middle portion 22 of the deflector 21 affords access to the screw and nut device 11. A fluorescent lamp 28 is accommodated in a channel 27 on the underside of the deflector, lamp holder 29 and spring clips 30 being carried by end pieces 31 suspended from the housing 5 through openings in the deflector 21. A transparent plastic lamp shade 32 is mounted by means of side flanges 33 which engage in slots 34 in the side wings. 25 -of the deflector. The usual capacitor 36 and choke 37, or other auxiliary control gear for the fluorescent lamp 28, are mounted in the housing 5. The latter is supported from the duct 1 by transverse partitions 40 which divide the air passage 6 into a series of compartments 41 for each of which there is a central air hole 8. A unit may be approximately the length of one lamp with six compartments 41 or it may have a length sufficient to accommodate more than one lamp. The arrangement is, also applicable to incandescent lighting or to a combination of the two kinds of lighting.

Abstract: 611,511. Magnetrons. MARCONI'S WIRE. LESS TELEGRAPH CO., Ltd. July 3, 1945, No. 16981. Convention date, Nov. 19, 1943. [Class 39 (i)] In a magnetron comprising an anode structure defining a plurality of cavity resonators and surrounding a cathode, the resonators are formed as coaxial lines of rectangular crosssection, Fig. 6 (developed view). The anode may be made up of a stack of intermediate discs 30, Fig. 9, with a plurality of pairs of slots 33, 34, two end discs 31, Fig. 8, and two closure discs 32, Fig. 7. The pairs of slots 33, 34 may be parallel as shown or radial, the tongues 341 being parallel-sided or tapering respectively. The discs are copper laminations, silver soldered together, either by using thin sheets of solder or by silver plating the laminations. Some of the anode discs may have larger diameters than others, Fig. 3, the discs being interleaved so as to form cooling fins 11. In an alternative construction, the intermediate discs 30 are replaced by a solid copper block suitably machined or broached, to which the end and closure discs are soldered. An output coupling loop connected to the inner conductor of a coaxial line extends into one of the resonators, Fig. 4 (not shown). The cathode is indirectly heated and is supported by brackets 16, 17 which are secured to cups 12, 13 and support a bridge 161, 17<1>, 18 held together by insulating loops 18<1>, 18<11>. The sleeved disc 20 secures the cathode to the member 18. A disc 21 serves as an electron and heat shield. 22 and 23 are polepieces of an electromagnet. Specification 611,505 is referred to.

Abstract: 1,105,810. Measuring angular displacements electrically. AGA AKTIEBOLAG. April 13, 1967 [April 28, 1966], No. 17005/67. Heading G1N. The angular displacement α of a shaft is measured by coupling the shaft through electrical or mechanical gear ratios n and m to obtain angular displacements of nα and mα, feeding corresponding electrical signals through resolvers and mixers to obtain a signal representing sin(n-m)α, which can be measured and indicated. As shown (Fig. 1), an angular rotation α of disc 1 produces, through gear ratios n and m, angular rotations nα and mα of wheels 3, 4, each of which is coupled to a resolver 5, 6. The former has two perpendicular stator windings 7, 8 fed with voltages V sin nwt and V cos nwt, producing output voltage V sin (nwt + nα) and V cos (nwt + nα) from two perpendicular rotor windings 9, 10. In similar fashion resolver 6 produces output voltage of V sin (mwt + mα) and V cos (mwt + mα). These voltages are taken in pairs to multipliers 20, 21 and the outputs added to give at 22 V sin (nwt + nα). V cos (mwt + mα) - V cos (nwt + nα).

Abstract: 154,955. Kerr, W. J. July 9, 1919. Tampering with, preventing.-In a ballot-box a closure 4 for the slot 3, through which the voting cards are dropped, is operated from the exterior in such a way that it cannot afterwards be opened without destroying a panel 9, Fig. 1, 13, Fig. 2, or 16, Fig. 3, at the bottom. The sliding closure 4 is fitted with a spring 6 carrying a halfnut 5 adapted to engage a screwed rod 7 having an external milled head 8. When the closure has been moved to a certain extent, the spring moves the nut out of alinement with the screwed rod so that its re-engagement is impossible without destroying the bottom panel. The panel 9, Fig. 1, is provided with inside spring catches 10 engaging a flange on the bottom of the box. It may be grooved as at 12 to weaken it so that it may be opened by a tin-opener or burst in with a hammer. In a modification, Fig. 2, a separate perforated panel 13 is fitted between a ring 14 closing the bottom opening and an inturned flange 22. In the third form, Fig. 3, the bottom closure 16 is placed in position by means of a cord 21 passing through the top slot. The cord is attached to a rack 19 engaged by spring catches 20 so that the closure 16 is firmly held when the cord is pulled taut and released. The disengagement of the half-nut 5 from the rod 7 may be audibly indicated.

Abstract: 276,788. Clayden, F. July 14, 1926. Moulding shoe trees.-Fillers D, Fig. 7, for use in displaying shoes are made hollow and moulded from a mixture of granulated cork, sawdust, wood pulp, or the like, and gum. Moulding boxes, Fig. 1, with a plaster of Paris or like copy B of a last are made in two halves hinged together. With the mould open, each half is covered with wet calico or linen, paper, leather, &c. A mixture of cork and glue &c. is then packed evenly on the cloth. The mould is then closed and sufficient mixture is then added through the open side to make joint where the halves meet, leaving the filler hollow. The filler can be easily removed and dried and mav be treated with cellulose or paint. In a modified method, instead of wet calico, two strips of dry calico which adhere to the filler are used. The meeting edges of the calico are trimmed on removal from the mould. A cardboard stiffener E may be inserted at the toe of the filler which is then ready for finishing.

Title: Improved method for the production of amino acids
Filed: 1949-07-04
Abstract: In a method for hydrolysing a hydantoin having the general formula <FORM:0687486/IV (b)/1> wherein R and R1 each independently represents hydrogen or a monovalent organic radical having a carbon atom thereof attached to the hydantoin nucleus, to form a salt of a corresponding a -amino-monocarboxylic acid, one molecular equivalent of the hydantoin is heated with an aqueous solution of at least two molecular equivalents of an alkali metal hydroxide, or an alkali metal carbonate, at superatmospheric pressure to a reaction temperature above 130 DEG  C. for a time not greatly in excess of that required for completion of the hydrolysis reaction.  The reaction may be carried out in a continuous manner by passing an aqueous mixture of the hydantoin and alkali through a heated reaction zone at a pressure sufficient to maintain the mixture largely, or entirely, in liquid form.  Starting material hydantoins mentioned are hydantoin and hydantoins having in the 5-position methyl, ethyl, propyl, isopropyl, butyl, sec.-butyl, isobutyl, phenyl, benzyl, b -methylmercaptoethyl, (3-indolyl-methyl), dimethyl or diethyl substituents.
