Abstract: 996,847. Laminates. HILLS-McCANNA CO. Jan. 15, 1964, No. 1882/64. Heading B5N. [Also in Division F2] A valve diaphragm structure 46 adapted for flexing in a valve assembly between an open position (shown in solid outline in Fig. 1) and a closed position (shown in broken outline) in which it is tightly compressed against a valve seat comprises a flexible elastomeric body member 48 and a polytetrafluoroethylene liner 50 chemically bonded thereto at 52, the liner having a tensile strength and breaking elongation at least equal to that of the body member. Finely divided polytetrafluoroethylene resin is extruded through a screw extruder to form a film which is heated and continuously coined in an oven. Several films are laid in plies one on top of another with their axes of orientation of physical properties at uniform angles relative to one another and fused together to form a single sheet which is then cut to the required size and compressed and heated in a mould to form a liner member. The individual films may be fused together while simultaneously forming the member. The liner member is then immersed in liquid ammoniasodium to give it an active surface and assembled in a mould with the preformed body member which is coated with adhesive 54. Heat and pressure are applied whereby the body member is vulcanized and the liner chemically bonded thereto. The body member may include a reinforcing member 56 of rayon or nylon fabric. Specification 851,452, and U.S.A. Specifications 2,615,471 and 2,918,089 are referred to.

Title: Improvements relating to the casting of laminated metal articles
IPC: B22D17/00
Filed: 1966-01-14
Abstract: 1,095,816. Making hollow ware; casting composite hollow ware; stamping. HOOVER Ltd. Jan. 14, 1966 [Jan. 18, 1965], No. 1904/66. Headings B3A, B3F and B3Q. In a method of making a composite metal dishshaped article, by diecasting a metal about the outer surface of a dishshaped liner, the liner is placed on a projecting horn in the die and stretched thereover. A liner 2 is stamped into the shape of a frying pan from stainless steel and it has a flange 6 extending around its whole periphery, the dimensions of the dished portion being slightly smaller than those of the projecting horn 13 of a die half 10. The interior surface of the liner 2 is sprayed with a high-temperature lubricant, e.g. boron nitride, molybdenum sulphide or preferably graphite and water. The liner, prepared for bonding as described in Specification 775,595, is placed over the horn, leaving a clearance space 15 and a heating element 4 bearing aluminium spacers (27, 28) is located in a sliding block (21) in the ejector half (11) of the die (Fig. 6, not shown). The die halves 10, 11 are then closed and the liner is stretched to conform to the shape of the horn (Fig. 5, not shown), the lubricant preventing wrinkling. Molten aluminium is next fed through an inlet 16 by a piston and a secure bond of the two metals is ensured owing to the stretching of the liner. Zinc or copper may be die-cast on ferrous metal other than stainless steel or on titanium.

Title: Production of cumene hydroperoxide
Inventor: COOKE MAURICE DUDLEY
IPC: C07C409/10
Filed: 1958-01-21
Abstract: Cumene hydroperoxide, obtained by the oxidation of cumene, is concentrated by submitting the crude oxidate to fractional distillation, withdrawing an overhead fraction containing unreacted cumene and acid by-products and recycling this acidic fraction to the oxidation, adding "fresh cumene" (i.e. cumene which contains substantially no acid or water) to the fractionator as liquid reflux, and withdrawing concentrated cumene hydroperoxide from the still. The overhead fraction is preferably separated from aqueous liquid and washed with alkali, in order to remove acid, before it is recycled to the oxidation.  In a preferred embodiment, the concentration is carried out in two stages in series, the overhead fraction from the first stage being recycled to the oxidation, and part of the overhead fraction from the second stage (i.e. dry cumene substantially free from acid) being used as reflux liquid for both stages.  In an example, a cumene oxidation product containing 23,4% by weight of cumene hydroperoxide and having a pH of 9 is concentrated in two stages, both of which consist of a climbing film evaporator combined with a fractionator.  The final concentrate contains 82,5% by weight of cumene hydroperoxide and has a pH of 6,5.

Abstract: 560,524. Automatic regulation. ELECTROFLO METERS CO., Ltd., DUNGLINSON, B., and WEY, R. J. Feb. 15, 1943, No. 2437. Drawings to Specification. [Class 38 (iv)] To obtain constant output in a load circuit of constant impedance from an a.c. source of varying voltage and frequency, a saturated transformer has its primary winding in series with a high resistance to eliminate voltage variations and its secondary circuit has tuning elements to eliminate voltage variation with frequency. Two arrangements are described, one in which a condenser, an inductance and the load are in series, and another in which the load is in shunt to a part of the tuned circuit, particularly the condenser. Where the output is rectified the effect of changes in the resistance of the rectifier with ambient temperature are minimized by mounting it in close association with a mass of suitable material as by enclosing it in a container having large'heat capacity and supporting this by insulating members in a larger container filled with heat-insulating material. The voltage regulating means may be enclosed in a separate ventilated compartment.

IPC: B61L3/12
Filed: 1928-01-26
Abstract: 294,870. Siemens & Halske Akt.-Ges. July 30, 1927, [Convention date]. Track apparatus actuating signals on and other than on trains, and for stopping trains.-An apparatus carried by a train and adapted to be inductively influenced from the track or, conversely, a track apparatus influenced from a train, comprises in the relay circuit inductances and capacity, so dimensioned that after passing a signalling point, the relay current is strengthened, this being due to the known " tipping phenomenon " which depends upon the use of a saturated iron-cored inductance in the impulse circuit. Fig. 1 shows a circuit on a train including an alternator 1, a condenser 4, a relay 5 having a non- saturated core, an inductance 3 with a saturated iron core and a winding 2 on a core which coacts with a core 7 on the track which carries a winding 6 the circuit to which is closed through a contact on the signal arm 9 and a condenser 8. While running normally between signals, the relay 5 receives only small current and is not energized. At a clear signal, the inductance of the coil 2 is slightly increased on passing the core 7 and no effect is produced in the relay by the reduced current. At a danger signal, the inductance 2 is compensated by the action of the shortcircuited coil 6 and condenser 8, and owing to the " tipping phenomenon " the relay current is increased considerably and is maintained at a high value after passing the core 7, the relay remaining energized. Fig. 5 shows a similar apparatus in which the inductance 3 is combined with the coil 2 by means of a saturated yoke 11 on the core 10. In another modification a transformer is used to connect the generator and coil 2 to the inductance 3, condenser 4 and relay 5. The track circuit mav be re-arranged to be closed to indicate line clear by including the condenser 8 in parallel with the coil so as to be shortcircuited by the signal-arm contact 9. To restore the relay 5 after energization by the increased current, the generator is switched out and the voltage then gradually increased to its normal value.
