Abstract: 1,016,605. Collecting flue dust; converter Chimneys. YAWATA IRON & STEEL CO. Ltd. Sept. 4, 1962 [Sept. 28, 1961; Oct. 4, 1961], No. 33843/62. Headings F4B, F4J and F4X] In a system for recovering dust from the waste gases of an oxygen top blowing converter the waste gases are led from the converter mouth through a cooling device into a vertical flue in which they pass upwardly or downwardly into an inclined flue leading to a gas holder. Dust falls by gravity in the vertical flue into a dust box having an outlet pipe leading below the surface of water in a tank, and further dust is removed in the inclined flue by water sprays and passes through an outlet pipe into a further water tank. An electric dust collector may be provided immediately before the gas holder.

Novel 5-(omega substituted-ethyl or -propyl)- 2-oxazolidinones in which the omega substituent is halogen, cyano, carboxy, carbalkoxy, hydroxymethyl or halocarbonyl are obtained by the following methods. The 3-substituted-5- (2-haloethyl)-2-oxazolidinones are prepared by reacting a corresponding 3-substituted 3- pyrrolidinol with a carbonyl halide and reacting the product obtained with a tertiary amine. The 5-(2-chloroethyl) compounds may be converted into other 5-(2-haloethyl) compounds by reaction with a halide salt or into the 5-(2-cyanoethyl) compounds by reaction with an alkali metal cyanide.

Abstract: 1428246 Comparator BENDIX CORP 18 July 1973 [14 Aug 1972] 34256/73 Heading G4M A comparator has a six bit binary counter 16 receiving pulses from a clock pulse source with the least significant three bits of the counter feeding an octal converter 28 and the most significant three bits feeding a further octal converter 30. The octal converters each feed a respective series of contacts one series arranged in a repeating series of 8 for the lower three bits, the other series forming the more significant digits. Two slider tracks T 1 , T 2  each carry respective slider contacts 34, 36 arranged to engage opposed contacts of each series and carry diodes to form an AND gate providing a signal when the count corresponding to the position of the slides is achieved.

Abstract: 507,437. Making boxes. POLLAK, J. E. (Colditz, L., (trading as BREHMER, GEB.) ) Dec. 14, 1937, No. 34636. [Class 18] A box with shaped corner fillets 28, Fig. 4, is made on a machine provided with a table to support the work and a further support 11, Fig. 5, carried by the table and pivotally or laterally movable to allow for left- or right-hand stapling of the sides 34, 35 to the fillets. The table itself is also pivotally or slidably mounted on the framing of the machine so that it has a limited movement between stops to allow staples to be inserted in two adjacent positions 32, 33. As shown, the support 11 is pivoted at 12 and it can be swung to left or right to positions limited by stops 15 .. 18. In operation, a fillet is laid on the support 11 up against an adjustable stop at its further end, a base 29 with side members 30 attached is laid against a stop 26, and the two members are stapled together. A further side member 34 is then laid against a guide 25 and stapled in position. Blocks 22, 23 support the wedge 11 and the fillet 28, but these blocks are movable outwards by the thickness of a side member to accommodate such a member during a later stage of working. The support 11 can be held normally in a central position by means of a spring or light weight. The various guides and stops are duplicated on the opposite side of the machine to allow for the right- and left-hand working.

In machines for packeting articles in boxes, cartons &c. of relatively stiff paper board &c., the boxes are supplied in flattened form, opened out to the condition shown in Fig. 17, and the carton is filled and closed. The flattened boxes are fed forward in a raceway 14, Fig. 3, by a presser 15, the foremost one being arrested by spring detents 18, Figs. 3 and 5, on one side, and by a lip 19<a> of a sliding detent 19 on the other. A reciprocating head 30 descends and a blade 42, carried thereby, enters between the side walls a, b of the foremost carton. A secondary blade 44 rotatable about a vertical axis, and also carried by the head 30, enters between the side wall a and an end wall d. The shaft carrying the blade 44 is rotated through a right-angle and erects the blank into the condition shown in Fig. 14, the left-hand edge in Fig. 5 escaping from the spring detent 18, and the detent 19 is slightly retracted to engage the next succeeding blank. A projection on the blade 42 engages the box blank, which is carried downwards towards a fixed guide 57, Figs. 3 and 9. The inclined portions 57<a> turn the tabs i, j inwards, and on the box being moved endways by arms 75 on an endless conveyer 59, the tabs are turned up into the positions shown in broken lines in Fig. 9, the bottom e and flap f still projecting downwards. Continued movement of the carton brings this portion into contact with a folder 78 having the successive cross-sections shown in Figs. 1<c>, 1<d>, 1<e>, forcing the flap f between the tabs i, j and the side wall a, and closing the bottom. The carton then passes to filling and closing mechanism.

Abstract: 849,040. Decorative electric lamp bulbs. GENERAL ELECTRIC CO. Oct. 29, 1958 [Nov. 1, 1957], No. 34682/58. Class 93. The transparent glass bulb of an electric, especially incandescent, lamp has a lightrefracting coating on at least part of its exterior surface comprising faceted particles of a transparent organic plastic of a minimum width dimension of at least 1À5 mm. firmly attached in random oriented manner to the glass surface by being at least partly imbedded in a relatively thin layer of a transparent organic lacquer on said surface. The particles may be of clear or coloured polystyrene, acrylic resin, or cellulose acetate, and may be additionally secured to the lacquer by small webs integral with the particles and diffused into the lacquer at their areas of contact therewith or by the provision of a clear or coloured transparent lacquer top coating into which the particles are diffused and which is itself diffused into the base coating of lacquer. The lacquer may be of cellulose acetate (dissolved in acetone) or butyrate and may be applied by dipping or spraying. The particles may be in the form of regular or truncated cylinders, prisms, pyramids, or cones, or in the form of approximately round beads with one or more flat facets. By dipping the lacquer coated bulb into a solvent both for the lacquer and the particles, and by then applying and pressing the particles thereon, the contact surfaces of the particles are diffused into the lacquer. As shown in Fig. 2, webs 16 diffused into the lacquer coating 12 as indicated at 17 and into which the particles 13 are themselves diffused as indicated at 18 are formed by applying over the particle coated area of the bulb a cellulose acetate lacquer coating 19 containing a solvent for both the lacquer coating 12 and the particles 13. The coating 19 is preferably colourless. The webs may be formed from the particles themselves by applying, in place of the lacquer coating 19, a solvent for the particles, if desired before complete volatization of the solvent in the layer 12. The particles may be applied by dipping the bulb into a cellulose acetateacetone lacquer, allowing to dry, dipping in acetone, placing the bulb in a container containing polystyrene particles, inverting the container, and finally dipping the particlecoated bulb either into cellulose acetateacetone lacquer or into a mixture of xylene and turpentine.

In order to eliminate distortion in the insulating block 40 of a carrier for connecting an integrated circuit to a printed circuit 26 for example, caused by the engagement of tubular socket contacts 62 in apertures 50, the aperture ends and sockets are contoured as shown in Fig. 4, so that the resultant stress developed in the block lies in a medial plane between the aperture ends.
