Title: Process for adhesive bonding of glass and ceramic products
Inventor: BECKER ROBERT
IPC: B32B27/00
Filed: 1964-11-13
Abstract: In the bonding of glass- or ceramic-to-glass-, ceramic-, metal-, wood-, plastics-, or other materials by an epoxide resin and a hardener, the epoxide resin used is an organo-silicon epoxy compound containing per molecule one or more epoxide groups directly linked to silicon (i.e. having a C-Si linkage), the remaining silicon linkages being to HC, alkoxy, aroxy, H or O. The organo-silicon epoxy compound may be mixed or condensed with other epoxy compounds, may contain per molecule at least two organic radicals containing epoxy groups, or may contain in addition at least one Si-OR or Si-H group and may then be used as a primer in bonding glass-or ceramic-materials to one another. In examples: (1) clean glass blocks were sprayed with a 1% ethanol solution of 3,4-epoxy butyl trimethoxy silane, dried, and hot-pressed together with an interposed coating of an epoxy resin and dipropylene diamine as hardener; (2) a 0.5% solution in tetrahydrofuran of 1 - [3 - (2,3 - epoxy - propoxy) propyl] - 1,3-dimethyl-1,3-diphenyl-disiloxane was used as in (1); (3) bonding of glass blocks was effected with a mixture of the materials used in Example (1); (4) a mixture of an unhardened epoxy resin and bis-1,7-[3-(2,3-epoxy-propoxy-propyl]-1,3,3,5,5 7 - hexamethyl - 1 7 - diphenyl - tetrasiloxane was heated with stirring, cooled, and after the addition of dipropylene triamine used to bond glass blocks without heating; (5) the mixture of Example (3) to which dipropylene triamine was added after heating and cooling, was used to bond, with heating, glass blocks previously sprayed with an ethanol solution of 3,4-epoxy-butyl-trimethoxy-silane; (6) glass blocks were bonded, with heating, with a mixture of (a) bis-1,3-[3-(2,3-epoxy-propoxy)-2-methyl - propyl] - tetraphenyl - disiloxane, partially hardened with dipropylene triamine, and (b) a further quantity of the same disiloxane; (7) glass blocks were heat-bonded with the disiloxane of Example (6) which had been preheated with phthalic anhydride and subsequently cooled.  The bonds are stated to be colourless and resistant to the action of water. Figures for dry and wet bond strengths are given in connection with the following bonds: glass/aluminium, glass/iron, glass/wood, glass/ceramic (porcelain), ceramic/ceramic, and ceramic/aluminium, iron or wood.  The surfaces of all materials were precleaned by conventional methods.

Title: Combined Preparation of Electrode Binder Pitch and Carbon Black Feedstock
Inventor: ROZA ABRAHAM GERRIT ALEXANDER
IPC: C10G9/00
Filed: 1968-10-03
Abstract: 1,178,528. Making carbon black feedstock and pitch. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 3 Oct., 1968, No. 46915/68. Heading C5E. Electrode binder pitch (EBP) and carbon black feedstock (CBF) are made from a hydrocarbon oil, e.g. a petroleum distillate or cycle oil from catalytic cracking boiling below 600‹ C., by cracking the oil and separating a residual fraction which is subjected to a heat soaking, separating an EBP from the heat soaking products, and blending a minor proportion of the EBP with a major proportion of a middle distillate from the cracking and/or heat soaking products, to form the CBF. Heat soaking means subjecting the residual fraction in liquid state to an elevated temperature, preferably 400‹ to 450‹ C., for a relatively long time, e.g. up to 2 hours. Lower temperatures necessitate longer times, and the time may be decreased by passing air through the soaker. Heat soaking increases the proportion of toluene-insoluble components in the residual fraction. The EBP obtained may be distilled to produce an EBP having the desired softening point. Various cracking processes using temperatures above 400‹ C. are described. Seven specific examples are described, giving relevant cut points, yield of gas and distillates &c., and in one example a heat soaking time of 26 hours is mentioned. The residual fraction for heat soaking should have an IBP lying between 150‹ and 400‹ C.

Title: Controllable magnet system
Inventor: BAERMANN MAX
IPC: B23Q3/154
Filed: 1968-10-07
Abstract: 1,210,744. Magnetic holding devices. M. BAERMANN. 7 Oct., 1968 [6 Oct., 1967], No. 47463/68. Heading H1P. [Also in Division H2] A switchable permanent magnet system comprises at least one permanet magnet in a magnet circuit having two interruptions, one of which forms a working air-gap, and an armature which can be moved from a first position bridging one of the interruptions to a second position bridging the other interruption by means of a current pulse applied to a winding surrounding the armature. As shown, Fig. 1, a plurality of annularly disposed, alternately poled permanent magnets 2, 3 are provided with upper pole shoes 5, 4 and lower pole members 7, 6 respectively defining upper and lower air-gaps. Coils 10 are located in the spaces 26 between the magnets and surround armatures 9 which are shown bridging the lower air-gaps 8 in which position the magnet is in the "full on" condition. When a current pulse of correct polarity is applied to a coil, poles are generated in the associated armature in such a sense that it is repelled from the lower pole members and attracted to the upper pole pieces to which it moves and bridges thus shunting the magnetic flux from the working air-gap 11 defined between the upper pole pieces and an eddy current brake disc 12. The braking force may therefore be reduced by switching selected armatures to their upper positions and when all the armatures are so disposed the magnet is effectively switched off. If the magnet system is to be rotated in use the armatures are restrained from radial movement due to centrifugal force by connecting their inner ends to link structures by means of hinges, the links extending radially towards the centre of rotation near which they are hinged to the base-plate. The inner and outer ends of each armature may have recesses which partially surround the opposite sides of the coil, Fig. 3 and 4 (not shown). Spring loaded plungers may be located in the upper and lower polepieces to cushion the movement of the armature and to reduce the current required to move the armature, Fig. 5 (not shown). The structure may be used in stationary and rotary magnetic chucks, locking devices, and value controls as well as eddy current and hysteresis brakes and clutches. Additional permanent magnets may be provided bridging the working air-gaps.

Abstract: 1395245 Compensating for light source variations in a smoke detector PYROTECTOR Inc 16 Oct 1972 [13 Dec 1971] 47590/72 Heading G1A In a smoke detector system comprising a light source and a photo-resistor Figs. 1 and 2 (not shown) positioned to view smoke particles the detector's sensitivity is varied inversely with respect to any variation in the source intensity thereby eliminating the effects of variations in the supply voltage on the system. In the Fig.3 embodiment the photo-resistor Cl is connected to the output of a voltage control portion VC of the source and detector circuit, the voltage control portion comprises a neon lamp N2 a rectifying diode D1 and a capacitor F2. The effect of these components is that the higher the A.C. supply voltage is, the earlier in each cycle that the neon lamp conducts and the lower the effective charge on the capacitor F2 becomes (and thus the lower the voltage across the photoresistor C1). A set of Figures, Figs. 4-9 (not shown), are disclosed illustrating this effect. In operation the photo-resistor receives the scattered light and when its resistance drops to below a predetermined value the voltage of junction J1 attains a high enough value to start a neon bulb N1 conducting thereby triggering a semi-conductor rectifier SCR and re-energizing an alarm A.

Abstract: 1,172,513. Polymer coated particles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 2 Nov., 1966 [11 Nov., 1965], No. 47901/65. Heading B8C. [Also in Division C3] Solid particles, e.g. of pigments, are encapsulated with an addition polymer by first adsorbing on their surface a water-insoluble polymer stabilized in the aqueous phase by a compound containing an anchor component associated with the adsorbed polymer and a pendant chain-like hydrophilic component which is solvated by the aqueous phase thus providing a stabilizing sheath around the particles, and subsequently encapsulating the treated particles by carrying out an aqueous emulsion polymerisation process in the presence of the particles dispersed in the aqueous phase. The preliminarily adsorbed polymer must be one which is dissolved or at least swollen to the extent of at least 1% by weight by the monomer to be polymerized. The polymer adsorption may be effected by modifying a dispersion of the particles in a solution of the polymer e.g. poly(methyl methacrylate) and the stabilizing compound in a polar organic liquid, by adding water so that the resulting mixture is a non-solvent for the polymer but continues to solvate the chain-like hydrophilic component of the stabilizer. In another form, a dispersion of the particles in an aqueous solution of ionized polymer and stabilizing compound is modified by altering its pH value such that non-solvated un-ionised polymer is formed; alternatively, un-ionised polymer may be formed by adding a polyvalent metal ion to a solution of an ionised acidic polymer. Preferably the adsorbed polymer contains polar groups to promote adsorption. The stabilizer may be added before or during the modification. Its hydrophilic component contains highly polar groups, and may be poly- (ethylene oxide) or a copolymer with a minor proportion of e.g. polyvinyl pyrrolidone. Its anchor component may be polymeric and similar to the adsorbed polymer. The stabilizer may be non-ionic but may be supplemented during the aqueous emulsion polymerization by an ionic stabilizer. The aqueous emulsion polymerization is of the conventional type wherein a monomer is dispersed in an aqueous phase containing an initiator and surface active agent. The resulting encapsulated particles are stated to be of use in the preparation of pigmented coating compositions.

The rolls may be shaped to produce triangular, hexagonal, or nonagonal tubing, or four rolls may be used to provide square tubing. The tube is supported on a fixed tapered mandrel 204 during rolling. Two sets of rolls may be arranged in tandem in a common housing 23 (as shown in Fig. 1, which shows a known rolling apparatus; see Specification 1,305,769). The housing is reciprocated relative to a casing 11 which is itself reciprocated. The relative movement between housing and casing causes the rolls to move along longitudinal cam tracks within the housing, and to thereby be moved radially towards the tube during each rolling step. The profiles of the cam tracks and of the mandrel determine the reductions in wall thickness and diameter suffered by the tube. The mandrel is fixed by a holder 36, whereas the tube is indexed axially (but not rotated) by a holder 38.
