Patent GB-369441-A (GB)
Title: Improvements in or relating to boxes or cartons
IPC: B65D5/54
Filed: 1931-04-23
Abstract: 369,441. Boxes or cartons. HARTMANN, C. W., Lyngby, near Copenhagen. April 23, 1931, No. 12091. Convention date, May 2, 1930. [Classes 18, 66, and 94 (i).] In a cardboard &c. box or carton from which an end 4 may be cut or torn and then used as a cover to the open end thus produced, the flanges 5 of this cover are, before severing, continuous with the plane sides of the carton, and the rim of the open end can enter these flanges so that the height of the carton fitted with the lid is less than its height before the lid is detached. The lines along which the end is severed are weakened by perforations 3, and slits, groovings, &c. 6 are-formed in the sides so that the latter can be pushed in to decrease the area of the open end. If a lining is pasted in the carton, a strip 9 of paste is applied over the perforations 3 to ensure that the lining is torn regularly when the end 4 is detached. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in which the open end of the carton retains its original area and the cover is expanded or retracted so as to fit over or inside the open end respectively ; and both ends of the carton may be detached to form covers. The perforations 3 may be replaced by other forms of weakening or by simple markings. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in means for facilitating the bolting together of plates and the like
IPC: F16B37/04
Filed: 1919-05-14
Abstract: 140,262. Metropolitan Carriage, Wagon, & Finance Co., and Chandler, L. May 14, 1919. Bolting; locking nuts.-To facilitate the registering of holes in plates to be bolted together in railway-coach and like work, a nut is secured to one of the plates by a clip and is capable of slight lateral adjustment. The clip a, Fig. 1, which is riveted to the plate to be bolted, has a bent-up tongue b with a flange c and two side tongues c. The nut placed beneath the tongue b is held against rotation whilst the bolt is screwed into it.

According to the Provisional Specification, the rod carrying the brackets may be fitted with an arm, which is oscillated by a tappet &c. so as to rock the brackets &c., and the back rests may comprise one or more rotatably-mounted rods or tubes.
Patent GB-1085485-A (GB)
Title: Apparatus and method for producing a beam of accelerated liquid metal droplets
IPC: H01J27/02
Filed: 1966-03-21
Abstract: 1,085,485. Electrostatic generators; rectifying. UNITED STATES ATOMIC ENERGY COMMISSION. March 21, 1966 [April 6, 1965], No. 12249/66. Headings H2A and H2F. A method of producing a beam of alternatelycharged groups of liquid metal droplets comprises: forming liquid metal into droplets, inducing charge in the droplets as they are formed (the polarity of the induced charge reversing periodically), and accelerating groups of the droplets through an alternating travelling electric field, this field having the same period as the period of reversal of charge in the droplets. Preferably the groups are collected, according to charge, in two separate collectors, whereby a very high D.C. voltage is generated; from another aspect, the A.C. which induces charges in the droplets is thus rectified. As shown, liquid alloy from a container 30 is fed to a nozzle 18 vibrated ultrasonically at 33 to produce uniform-diameter droplets; the nozzle is earthed and opens into an evacuated bell-jar 39. A charge is induced in the droplets by a toroidal electrode 8 secured to a supporting rod 14. Further toroidal electrodes 9 to 11 are provided, and all are secured alternately to supporting rods 14, 15, connected to the output terminals 24 of a step-up transformer 20. Each group of droplets is at first attracted by the next electrode in its path, then (as the excitation voltage changes phase), is propelled by its momentum through the electrode opening, and is then repelled by this electrode and attracted by the next one. Positively-charged groups of droplets emerging from electrode 9 are preferably repelled laterally by a positive electrode 40 and are attracted by a negative electrode 41 to be collected in a container 44, while negativelycharged groups of droplets are similarly collected in a container 46. D.C. output terminals 50 are provided. Nozzle 18 may be connected to rod 15 instead of to earth; the earth centre tap 25 is in that case dispensed with.

Title: Apparatus and method for testing the contamination of moving liquids, in particular, of liquids contained in ampoules, and for automatic scrapping of ampoules
IPC: G01N21/21
Filed: 1965-03-23
Abstract: 1,103,656. Testing the contamination of liquids. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. March 23, 1965 [March 27, 1964], No. 12291/65. Heading G1A. Apparatus for testing the contamination of a liquid contained in an ampoule 3 in order to reject an ampoule containing liquid contaminated above a predetermined level, comprises an extended light source 1 producing a beam of light; polarizer, 2, and analyzer, 5, elements; a multiple slit diaphragm 4; and detector apparatus 6-8, including an amplifier. An ampoule 3 is mounted with the diaphragm 4 on a rotatable support 9 between polarizer and analyzer, the diaphragm preferably taking the form of a cylinder 10, Fig. 2 (not shown) of non-transparent material provided with vertical slits, which is arranged to move with the ampoule on the support 9. Light from the source 1 is polarized mainly in one plane, and the analyzer is arranged to have similar properties as the polarizer to cut down the constant background light intensity while retaining that of light scattered by contaminating particles. In operation, after rotation of the diaphragm and ampoule to such a speed that even glass splinters and bubbles in the liquid, rise, in the vortex produced, into the light path, the diaphragm is stopped by disconnection from the rotation mechanism, such that its slits are located symmetrically in the light path with respect to source and detector. The ampoule is stopped at the same time but, the contaminating particles continue to rotate with the liquid. Light scattered from the particles and the sides of the ampoule and a constant background light beam, somewhat diminished by the polarizing elements, is received by a photo-multiplier 6. The output is amplified by amplifier 7 which has one of its stages A. C, coupled to cut-out the signal components representing the background and light scattered by the ampoule. The amplitude of the amplifier output is analyzed by a discriminator 8 which emits a voltage or current pulse if a predetermined amplitude is surpassed, indicating an unsatisfactory level of contamination. The output may control an electro-mechanical ejector.

Title: Improvements in and relating to methyl silicone synthetic resins
Filed: 1945-05-16
Abstract: A methyl silicone resin of the type described in Specification 542,655, is extracted with a nitroparaffin containing 2-4 carbon atoms and the insoluble portion of the resin is recovered.  The products have improved curing and bonding properties, and less tendency to thermoplastic flow and are useful for making rigid coil forms and for adhesives or coating and impregnating varnishes generally, especially for glass fibres, asbestos sheet materials, or mica plates.  Before solvent extraction, other solvent such as toluene or ether present in the resin is removed by gentle heating. Extraction may be aided by agitation and gentle heating.  The product may be washed with acetone to remove solvent and then dissolved in toluol or xylol to form a varnish. The nitroparaffin and acetone used for washing may be recovered, leaving an oily dark residue which may be used as a plasticiser for silicone resins when the presence of low boiling-point materials is not objectionable.  The nitropropanes are particularly suitable solvents.  Specification 585,628 also is referred to.
