Abstract: 1,178,779. Phenols and phenyl esters. FARBWERKE HOECHST A.G. 14 March, 1968 [17 March, 1967], No. 12428/68. Heading C2C. A phenyl ester or a mixture of a phenyl ester and phenol are prepared by reacting a mixture of benzene, a saturated aliphatic carboxylic acid and molecular O 2 in the gas or vapour phase in the presence of a compound of a noble Group VIII metal having a maximum stable valency of at most 4. The Group VIII metal compound is a Rh, Ir, Pt, Ru or preferably Pd compound. The reaction is preferably carried out in the presence of an initiator, i.e. a carbonate or carboxylic acid salt of an alkali metal, Zn or Cd; a sodium phosphate or borax. In Examples (1) a catalyst comprising sintered silicic acid impregnated with K and Pd acetates is prepared, placed in a reaction tube at 170 C. and 5 atm. and a vaporized mixture of benzene, O 2 , acetic acid and K acetate passed over it to give phenyl acetate and phenol, the phenylacetate being hydrolysed to phenol with steam at 600 C.; (2) phenylacetate is obtained by passing benzene, O 2  and acetic acid at 170 C. and 1 atm. over a catalyst obtained by impregnating silicic acid with PdCl 2  treating the impregnated carrier with dilute aq. NaOH, washing and drying and depositing K and Cd acetates thereon.

Abstract: 809,425. Oil stoves. LION STAMPING CO. Ltd. April 12, 1957 [April 23, 1956], No. 12429/56. Class 126 In a portable oil-burning heater with an opening in the front of the casing for the radiation of heat after reflection, a reflector of curved cross section rises vertically to well above the burner and then slopes forwardly to the upper side of a gas outlet in the front of the casing above the opening. A vaporizing burner 16 mounted in the front compartment of casing 10 is fed from a tank 14 in the rear compartment. A reflector 22 with a lower part of curved cross section extends vertically to well above the level of the burner 16, and the upper part 26 of the reflector slopes forwardly to meet the front wall of the casing above a gras outlet 28. A door with a grille covers the front opening, and a wire dome over the burner forms a radiant. The reflector is spaced from the top of the casing so that the casing does not get unduly hot.

Abstract: 808,309. Wall coverings. ARTEX PRODUCTS (DECORATIONS) Ltd. April 18, 1957, No. 12724/57. Class 20(4) Plasterboard panels a are mounted on a skeleton structure b, c which is pressed against widely separated packs of a bonding mix e applied in a plastic state on a wall and which is held thereby in spaced relationship to the wall. The members b are horizontal and are affixed to the wall d by interposed bonding packs e and aligned in a vertical plane. The members c are vertical and are similarly affixed so that their outer faces are in alignment with the members b thereby to provide plane supporting surfaces for the plasterboard which may be secured to the structure by a thin layer of bonding compound and by nails f. An air-space g is left between the panels, members b, c and the wall d excepting where the bonding packs e are located. The bonding mix is made of materials which set without deleterious shrinkage and preferably may be of the material known by the Registered Trade Mark "Artex Backbond". The bonding packs e when fully compressed are preferably not less than one-eighth inch thick so that e.g. with members b, c being three inches wide and three-eighths inch thick, the space behind the plasterboard panels will not be less than one-half inch.

Abstract: 593,446. Correspondence control systems. BENDIX AVIATION CORPORATION. May 22, 1945, No. 12791. Convention date, Dec. 31, 1943.' [Class 40 (i)] In a correspondence control system, error signals from the motor of an. induction repeater at the controlled end are applied through an amplifier to a servomotor which drives the repeater motor and the controlled member into correspondence with the transmitter through a step-by-step mechanism. The Figure shows an arrangement in which movement of selsyn transmitter motor 15 causes a voltage to be induced in receiver rotor 30. This voltage is amplified by amplifier 33, and used to energize one winding of two-phase motor 18, which drives member 56 mounted on gear 43. Pin 55 carried on member 56 alternately imparts a step-by-step rotary movement to members 50 and 51 which are freely mounted, together with their associated gears 47 and 48, on gear 43, so that shafts 60 and 61 are rotated step-by-step to bring rotor 30 and the controlled member (not shown, but driven by stage 61) respectively into correspondence with the transmitter rotor. Member 58 carried on member 56 is configured to prevent any movement of shafts 60 and 61 when they are not being driven by pin 55.

Filed: 1955-05-03
Abstract: 769,642. Filter-presses. EIMCO CORPORATION. May 3, 1955 [Sept. 22, 1954], No. 12799/55. Addition to 754,152. Class 46. The expansible spaces, each bounded by an elastic ring, between adjacent filter plates of the press of the parent Specification are replaced by expansible spaces each bounded by telescoping annular parts, one on each plate. Mixture to be filtered is fed under pressure into the bottom of each frame 123 (the plates and frames being in contact-not as shown), the feeding being stopped when the cakes formed on each filter plate in a filter chamber almost touch. Excess mixture is then drained back into the supply pipe 136 and thereafter washing liquid is introduced through the same pipe and passes in the same direction as the filtrate through the cakes, leaving by pipes 138 and 140. Compressed air is next passed, again in the same direction through the cakes to dry them. Finally, compressed air is passed in the reverse direction to free the plates from the cakes, the air escaping through the pipe 136. The supply of fluid under pressure which has been holding the plates 150, 160 against the frames 123 is now cut off and the spaces between the plates are placed in communication with a source of vacuum whereby the plates are telescoped in pairs to the positions shown. The frames 123 are then simultaneously rotated by an offset shaft (not shown) to displace them from their positions between the plates and further frames diametrically opposed to them are thereby moved into position between the plates to enable filtration to be recommenced whilst the other frames are being freed from cakes. The plates slide along the frame-shaft and another shaft (not shown).

Abstract: 1,034,821. Applying container closures. A. SCHNYDRIG. April 3, 1963 [April 4, 1962], No. 13183/63. Headings B8C and B8T. A plastics sheet 25 is pressed on to a container 8 by a vertically movable pressure plate 20, and further downward movement of the plate depresses a supporting plate 9 against action of a spring 7 and provides a duet, defined by collar 3a of the supporting plates and a table top 2, through which hot air emanates to cause shrinkage of a depending portion of the plastics sheet. Fan-blown air is introduced into a cavity 10 which contains a heating element 14. The plastics sheets are severed from a roll of plastics film, during downward movement of the pressure plate, by a heated wire. In an alternative embodiment the supporting plate is not vertically movable and the passage of hot air to permanently formed ducts 207 (Fig. 4, not shown) is controlled by a valve. This embodiment is adapted for sealing containers of various sizes.

[Class 37] A resistance element for pyrometers consists of a platinum, osmium, or iridium wire en. closed between two bodies of porcelain, steatite, or similar ceramic material and embedded in a glaze layer filling the space between these bodies. A slightly conical porcelain tube 1 has an external helical groove containing a fine platinum wire 2, which may have a diameter of 0.2 mm The tube and wire are then covered with a glazing mass having a molecular proportion between silica and basic oxides of at least 5, magnesia also being present. A porcelain tube 3 which is slightly conical internally, is slipped over the tube 1 and the whole is heated until the glazing mass becomes viscous and fills the interspace so as to. enclose the wire 2 and the return conductor 4 in an air-tight manner. The wire 4, as well as the leading-in conductor 5 to the other end of the wire 2, is also of platinum or the like, but considerably thicker than the wire 2. The assembly is then introduced into the closed end of a tube 6 of a refractory metal alloy, for instance, of chromium, iron, and nickel, this tube being long enough to reach through the furnace wall and into the furnace with a length corresponding to that of the resistance helix. At the other end the tube 6 is fitted with a connection plate.
