Abstract: 1425397 Cellular films obtained from aqueous latices DESOTO Inc 23 March 1973 [30 March 1972 18 April 1972] 14144/73 Heading C3C Cellular films are made by drying an aqueous latex coating composition comprising an aqueous continuous phase having stably suspended therein polymer particles of an organic solvent-soluble resin, the particles being swollen by having absorbed therein a primary organic liquid which is substantially immiscible with the aqueous phase (i.e. at least half of the primary liquid which is initially placed in the aqueous phase migrates from this phase into the particles) and a secondary organic liquid that is at least partially waterimmiscible in the aqueous phase, which has a lower vapour pressure at ambient temperature than the primary liquid and being less readily absorbed by the polymer than the primary liquid, whereby when the latex is deposited and dried, the organic liquids and water will evaporate to produce a film containing opacityinducing cells. The polymer may be one having a glass transition temperature below 25‹ C., e.g. an ethylene/vinyl acetate copolymer which may contain a trace of methacrylic acid, together with one having a glass transition temperature above 30‹ C., e.g. polystyrene or styrene/divinyl benzene copolymer. The primary liquid may be an aliphatic hydrocarbon e.g. mineral spirits, naphtha, hexane, butane, kerosene or octyl alcohol, and/or an aromatic liquid, e.g. xylene or toluene, or an alkyl diethylene glycol acetate. The secondary liquid may be propylene glycol. In the examples the latex also included a dispersing agent (an ethylene oxide/isooctyl phenol condensate or sodium lauryl sulphate), a thickener (hydroxyethyl cellulose), an optical brightener, a pigment (TiO 2 ) and sodium bicarbonate.

Abstract: 753,628. Switchgear structures. ENGLISH ELECTRIC CO., Ltd. May 13. 1955 [May 14, 1954], No. 14180/54. Class 38(5) An indexing mechanism for locating two relatively-movable members in predetermined positions comprises driving means for effecting the relative movement, two indexing elements which move in correspondence with the relative movement of said members and which have between them an operative connection with mechanical advantage, a device associated with the faster moving element and capable of locking engagement therewith and means associated with the slower moving element which prevents locking engagement of the device with the slower moving element excepE when the slower moving element occupies one of a number of predetermined positions. The mechanism may be used in switchgear comprising a fixed portion 1 carrying isolating contacts 6, 7, 8, and earthing contact 41, and a portion 2 carrying contacts 12, 13, and movable along rails 3. Contact 12 is vertically movable by means of two screws 18 so that it may be engaged with one of the two contacts 6, 7 or 41. Screw 18 is actuated by handwheel 24 through bevel gears 20, 21 and carries an indexing and locking disc 26, bevel gear 20 and worm gear 27. Disc 26 has one slot in its periphery engageable with catch 28 secured to crank 29, the other end of the crank being pivotably connected to a slidable rod 31. The crank pivot pin 32 carries a gear-wheel 33 engaging worm 27 and secured to a disc 34 having three peripheral slots 37. A follower 38 rigidly secured to rod 31 is biased by spring 39 to bear against the periphery of disc 34. To actuate screws 18, the movable portion 2 is fully withdrawn, when rod 31 is aligned with recess 3a in rail 3. Lever 30 is raised, lowering rod 31 into recess 3a disengaging follower 38 from disc 34 and catch 28 from disc 26. The contact 12 may then be raised or lowered by handwheel 24, the disc 34 being driven through worm gear 27 and 33. Lever 30 is released so that follower 38 bears against disc 34 until it engages a slot 37. At this instant, the slot in disc 26 is opposite catch 28 which moves into the slot as rod 31 lifts clear of rail 3. The portion 2 is now free to be moved, the contact 12 being aligned with one of the fixed contacts.

Jitter may be added to the reference frequency for the first two (rough) counts and removed for the final (accurate) count. The offset may be constant irrespective of which harmonic of F R  is selected, or may depend on F R . Two forms of generator 64 are described, Figs. 2 and 3 (not shown).

Abstract: 1,261,325. Control of D.C. motors. SQUARE D CO. 31 March, 1970 [28 April, 1969], No. 15071/70. Heading H2J. The series field winding F of a battery-fed motor has a shunt comprising a resistor R and normally-open contacts 10 of a contactor 12. When the motor operates with a weakened field and the load increases, the current through coil 18 becomes sufficient to overcome the effect of coil 44 and the resilient bias on reed contact 46 which disengages from contact 50 and engages contact 48. Coil 44 is de-energized, and transistor T becomes non-conductive so that coil 12 opens the contacts 10. The engagement between contacts 46, 48, energizes coil 42 which aids the coil 18 to maintain the engagement, a capacitor C providing an initial increase of current through the coil 42. The coils 42, 44, are each in series with separate potentiometers 56, 64. Simultaneous actuation of contacts 30, 32, disables SCR control 26 and energizes relay 36 which closes contacts 20, 38.

Title: A method of coating a material, such as paper, with wax or the like
IPC: B29C48/15
Filed: 1964-04-13
Abstract: In a process of applying fluent material to a moving carrier p  web by an extrusion nozzle to form a coating on the web, the web is sufficiently free, at the point where it passes the nozzle, to be displaced away from the nozzle by the material discharged on to it by the nozzle.  The pressure of discharge of the coating material from the nozzle may produce a change of the direction of movement of the web in the neighbourhood of the nozzle and the thickness of the coating may be dependant, in part, on the discharge pressure. Preferably the carrier web is fed past the nozzle so that it tends to be kept pressed against the nozzle such that before the fluent material has begun to leave the nozzle the web hurls directly against the nozzle.  The coating may subsequently be subjected to a glossing or other surface treatment.ALSO:A material, e.g. paper, is coated on one or both sides with wax or similar fluent material in molten form by passage of the material under and/or over an extrusion nozzle such that at the point where it passes the nozzle the material is sufficiently free to be displaced away from the nozzle by the fluent material discharged on to it by the nozzle.  The discharge pressure may cause a change in the direction of the movement of the material in the neighbourhood of the nozzle and also controls the thickness of the coating.  The coating may be subjected to surface treatment, e.g. glossing.

Title: Improvements in or relating to hydrogenated furane derivatives and method of producing same
IPC: C07D307/46
Filed: 1952-06-17
Abstract: Thermosetting resins are manufactured by polymerization under acidic conditions (e.g. at pH 2.5 and 300 DEG  F.) of partial hydrogenation products (or fractions thereof) obtained from condensation products of furfural with one or more ketones having two hydrogen atoms on an a -carbon atom (or fractions containing at least 60 per cent thereof) by saturation of all the carbon-to-carbon double bonds outside the furane ring and part of those in the ring, but not more than 65 per cent of the total carbon-to-carbon double bonds.  The products may be used as binders or friction augmenting particles in friction elements such as brake linings or clutch facings.  In an example, a partially hydrogenated furfural-acetone condensation product is allowed to stand with diethyl sulphate and then heated to 300 DEG  F.ALSO:The process of the parent Specification is modified by continuing the hydrogenation until the amount of hydrogen absorbed is in excess of the amount required to saturate all the carbon to carbon double bonds outside the furane ring but not more than about 65 per cent of that required to saturate all the carbon to carbon double bonds (i.e. those outside and inside the furane ring).  The process may be applied to the initial product of the alkaline condensation of furfural with one or more ketones having two hydrogen atoms on an alpha carbon atom (which may first be rendered neutral of slightly acid and/or dehydrated), or to a residual fraction, comprising at least 60 per cent thereof by weight, produced by heat distillation of the initial condensation product.  In examples (1) the partially hydrogenated furfural-acetone condensation product, designated HA, of example (1) of the parent Specification is further hydrogenated to various extents in the presence of fresh catalyst; (2) the acetone in (1) is replaced by methyl ethyl ketone, and (3) by diacetone alcohol. Other ketones specified are mesityl oxide, acetonylacetone and cyclohexanone.ALSO:Coating compositions comprise, in a solvent if necessary, a mixture of diethyl sulphate with a partial hydrogenation product (or fraction thereof) obtained from a condensation product of furfural with one or more ketones having two hydrogen atoms or an a -carbon atom (or a fraction containing at least 60 per cent thereof) by saturation of all the carbon-to-carbon double bonds outside the furane ring and part of those in the ring, but not more than 65 per cent of the total carbon-to-carbon double bonds.
