Abstract: 804,937. Automatic gramophones. INDUSTRIAKTIEBOLAGET LUXOR. June 26, 1957 [June 27, 1956], No. 20161/57. Class 40 (2). In an automatic gramophone, a record-changing centre-spindle is divided into two or more sections pivoted to the 'turntable so that they may be swung into an inoperative position in recesses in the turntable. As applied to a spindle for use with 45 r.p.m. records, three sections 24 with a recording- supporting shelf 25 are interspaced between three sections 27 with a knife 28 to separate the lowest record of the stack 26; slotted cam portions 29, 30 therein are engaged by a 6-armed disc 31 (Fig. 5), raised by a shaft 32 axially movable by record-changing mechanism (not shown), whereby the knives 28 are first inserted above the lowest record, and the shelves 25 are then retracted to allow that record to fall. The shaft 32 may be coupled with the speedchanging device so that when the latter is set other than to 45 r.p.m. the disc 31 is lowered to allow the sections 24, 27 to swing down into recesses 34 in a rubber mat 23 on the turntable 22; holes 35 accommodate the shelves 25 and knives 28, and small-hole records may then be centred on the top 33 of the shaft 32, or on a small-diameter record-changing spindle fitted in place thereof. A disc 17 secured to a bearing sleeve 16 rotatable in a fixed tube 15 supports the turntable, and by means of recesses 20 engaged by projections 21 on the turntable transmits the drive from a motor 3 via a cone 5, axially adjustable change-speed wheel 10, cone 7, and roller 11, against which a pressure roller 12 mounted on a pivoted arm 13 presses a rubber disc 19 secured to the lower ends of bolts 18 depending from the disc 17.

Title: Improvements in or relating to the stabilization of aqueous anionic dispersions of partially polymerized dimethylol urea
IPC: C08J3/03
Filed: 1944-10-23
Abstract: A stabilised colloidal aqueous anionic dispersion of a partially polymerized dimethylol urea is prepared by ageing an aqueous solution of dimethylol urea containing dissolved sulphur dioxide sufficient to maintain a pH value of 0.5 to 3.0, until a haze indicative of the colloidal state develops as described in the parent Specification, and then neutralizing the free acidity. Ammonium hydroxide and sodium hydroxide are the preferred neutralizing agents.  The pH may be adjusted to about 6.5, or solutions containing a high proportion of solids may be made neutral or slightly alkaline to phenolphthalein. The pH may even be raised as high as 10.  Three specific examples of the invention are given.  In one of them, the stabilized colloidal solutions are subjected to electrophoresis to demonstrate their anionic nature.ALSO:A stabilized colloidal aqueous anionic dispersion of a partially polymerized dimethylol urea is prepared by ageing an aqueous solution of dimethylol urea containing dissolved sulphur dioxide sufficient to maintain a pH value of 0.5 to 3.0, until a haze indicative of the colloidal state develops as described in the parent Specification and then neutralizing the free acidity. Ammonium hydroxide and sodium hydroxide are the preferred neutralizing agents. The pH may be adjusted to about 6.5 or solutions containing high proportions of solids may be made neutral or slightly alkaline to phenolphthalein.  The pH may even be raised as high as 10.  Excess alkali causes precipitation of the colloid.  The stabilized solutions may be precipitated by addition of acids or of aqueous solutions of salts having acid reactions such as aluminium sulphate or sodium acid sulphate.  By this means the colloidal polymer may be precipitated upon fibrous material such as asbestos, kraft paper stock or sulphite paper stock, and may then be cured by heating to 240-300 DEG  F. Paper formed from such treated stock, dried and the resin cured has improved wet strength.  Three specific examples of the invention are given.  In one of these the stabilized colloidal solutions are subjected to electrophoresis to demonstrate their anionic nature.

Title: Ion exchange resin
Inventor: BORMAN WILLEM FREDERIK HENDRIK
IPC: C08G65/48
Filed: 1963-05-23
Abstract: The invention comprises resins containing at least 100 units of formula <FORM:1048273/C3/1> wherein the oxygen atom of one unit is connected to the benzene nucleus of the adjoining unit, Q is hydrogen, an aliphatic hydrocarbon or halohydrocarbon radical free of a tertiary a -carbon atom, Q1 is the same as Q or is a halogen, an arylhydrocarbon or haloarylhydrocarbon radical, a hydrocarbonoxy or halohydrocarbonoxy radical free of an aliphatic tertiary a -carbon atom, and Q11 is the same as Q1 or is one of the groups nitro, amino, diazo, nitrile, carboxyl, quaternary ammonium, P(halogen)2, As(halogen)2, PO3H2, PO2H2, of these groups in the majority of the units in the molecule.  The resins containing nitro groups may be obtained by nitrating a resin obtained by reacting oxygen with the corresponding phenol in the presence of a tertiary amine and a cuprous salt soluble in the amine and capable of existing in the cupric state.  The nitro-containing resin may be reduced to the amino-compound, which may be diazotized; the diazo groups then may be replaced by the other groups.  Alternatively, nitro-containing polymers may be obtained from nitro - substituted phenols, and amino-substituted polymers may be obtained by amination of polymers containing halogen atoms attached to the aromatic nucleus.  In examples a polymer is nitrated, converted to the amino compound, diazotized, the diazo compound is converted to the nitrile and then to the carboxyl resin, and the amine compound is converted to a quaternary ammonium compound.  The resins may be used as ion-exchange materials.

Abstract: 157,499. Candee, B. C., Moeser, F., and Pierce, W. N. Aug. 22, 1919. Fusible cut-outs; binding posts and terminals. - A refillable cartridge fuse comprises two concentric insulation tubes arranged to slide upon each other. The inner one has an opening or openings for the insertion of the fuse. The cartridge cannot be inserted in its contact clips unless fully closed and the operator is thus protected from injury. According to Fig. 2 the inner tube .1 has heads 5, 5<a> both constituted by telescoped cups facing each other and preferably filled with asbestos, within which are screwed the contact blades 17, 18. These blades form the fuse terminals. The flat contact blades are slit at their inner ends to take the ends of the fuse strip 3. The fuse is clamped at each end by a cam leyer 36 carried by a yoke 33 shown in Fig. 4 which embraces the terminal and co-operates with a wearing strip 37, prefer. ably of steel, positioned between the terminal plate and the cam. The outer tube has an end cup 12 fixed to it, the other 11 being fixed to the inner tube. Stops carried by the outer tube slide in the opening in the inner tube and limit the extent to which it may be withdrawn. In a modification, shown open in Fig. 7, the inner tube has two side openings 40 and has split metal ends 42, 43 secured therein, these being closed to grip the fuse 47 by the same screws 44, 45 and secure them in the tube. The end cap 49, which forms the terminal of the cartridge, is screwed upon a boss 52 in the end member 42, and fixed by solder or the like, whilst the other end cap and terminal 50 is rotatably secured to the outer tube 41 by its rim 60 and has a screwed hole 55 which engages a screwed boss 56 to close the fuse. A stop 57 on the outer tube co-operates with a longitudinal groove 59 with closed ends on the inner tube 39. According to Fig. 2<x> an inner tube 2<x> open at one side carries heads 11<x> constituted by single cup members facing outwardlv, within which contact blades 20<x>, 21<x> are secured. An end cap 6<x> is secured to the outer tube 1<x> and another 7<x> to the inner tube. The inner tube heads and end caps are perforated, the perforations of the former being covered by screens 15<x> secured within the heads 11<x>. A stop 29<x> co-operating with a closed slot 28<x> in the inner tube limits the extent of movement of the outer tube. The fuse strip in this form has a longitudinal slot at one end and a transverse slot at the other and is secured to the contact blades within the cartridge by means of screws 23<x> which are prevented from complete withdrawal by stops 25<x> formed in them. The contact blades of the forms shown in Figs. 2 and 2<x> are secured to the heads of the inner tube by means of a meta. bridge, fastened across the diameter of the head, and to which the blade is rivetted at the centre. The blades are a snug fit in the end caps and leads, but allow relative movement where required.

Abstract: 725,794. Making metal bands for bottle closures. SENIOR & CO., Ltd., J. H. Aug. 14, 1953 [Aug. 19, 1952], No. 20831/52. Classes 83 (2) and 83 (4). In, a method of making clip type bands for bottle cap closures and assembling the bands together with flanged lids, the bands are bent so that their ends overlap and are then placed within an aperture of the required size and are expanded by a tool so that the projecting tongue at one end of the band engages within the aperture at the other end of the band. After insertion of the lid in the inverted position, the edge of the band is then flanged beneath the lid. A machine for carrying out the method comprises an intermittently rotating carrier 11, Fig. 2, to which pre-curled but unflanged bands 21 are fed from a curling device 17 by a shoot 24 and feed mechanism 30. The carrier has apertures 13 which carry the blanks intermittently to the expanding tool 40 actuated by an eccentric 61 on a main drive shaft 62. The tool 40, Fig. 3, comprises a sleeved head 56 carrying a spring- loaded plunger 52 to which a cup-shaped head 47 carrying pivoted fingers 45 is attached. On engagement of the plunger 52 with a fixed plate 63 of the machine the head 56 engages cam faces 60 on the fingers 45 so that they move radially outwards against the action of a retaining spring 53 to expand the band 21 into engagement with the walls of the aperture 13, the projecting tongue and slot on the ends of the band being thereby engaged. The bands 21 are then carried intermittently to a station at which flanged lids 66 are inserted in the inverted position by the operator. At the next station a tool 67, Fig. 5, having a stepped end 72, 73 for engaging the upper edge and inside face of the band 21 flanges the lower edge of the band against a recess 74 in the fixed plate 63. A spring-loaded plunger 76 holds the lid 66 in position and has projections 78 movable in a slot 79 on the tool to engage the edge of the band 21 and eject it from the tool 67 after the operation has been completed. The lid is then carried by the feed-plate 11 to a position above an aperture in the lower plate 63 through which it is ejected by a vertically-reciprocating tool 80. Intermittent rotation of the feed-plate 11 is imparted by a reciprocating pawl 14, the plate being located in each position by a second spring-urged pawl 91.
