Abstract: 498,561. Water-tube steam boilers. FOSTER WHEELER, Ltd. (Foster Wheeler Corporation.) Feb. 4, 1938, No. 3560. [Class 123 (ii)] A water-tube steam boiler comprises a steam generating section 16, two or more separate furnaces 14, 15, flanking it, and a superheater encountered by gases from both furnaces as they proceed to the boiler section, some superheater tubes 30 being in the path of gases from only one of the furnaces, and the remainder 28 being swept by all the gases. The boiler section includes upper and lower drums 17, 18 connected by tubes 19 grouped in longitudinally spaced pairs. The furnaces are lined by water walls 20, 21, the tubes being staggered at the entrance to a chamber 25 at the rear of the boiler section to form slag screens 26, 27. Superheater tubes 28 are L-shaped with vertical loop portions adjacent the inlet to the boiler section. The other superheater section comprises vertical tubes 30 extending between headers and parallel to slag screen 27. The gases descend at the front of the boiler section to a flue containing tubular air heaters 35 .. 37 which are connected at one end to a forced draught fan and at the other to a box communicating with boxes 43, 44 delivering air to burners 22. In a modification the two superheater sections each consist of L-shaped loops their vertical portions being longitudinally spaced, and the entrances to chamber 25 from the two furnaces are so arranged by means of extensions of the furnace walls that the gases from one furnace pass over both superheaters and those from the other over only one.

Abstract: 554,177. Vacuum cleaners ; motor controllers. AKTIEBOLAGET ELEKTROLUX. March 19, 1942, No. 3649. Convention date, May 5, 1941. [Classes 8 (i) and 8 (ii)] [Also in Group XXXVII] A vacuum cleaner is provided with a dustcollecting container 10 and a cover 11 having upper and lower walls 19, 20 and carrying a non-collecting filter 15 having concentric circular folds and a motor-fan unit 14 disposed side by side. The space between the walls is divided into a suction chamber and a pressure chamber containing the motor. Air is drawn into the container and after passing through the filter flows down the space between the motor-fan unit and an outer casing 23 of the unit over the motor to the outlet. The motor is resiliently supported by rubber rings 32, 33, the rings 33 being ribbed to form air guides. The casing 23 is formed with rubber feet 35, and a co-operating leg 36 is provided at the other end of the cover. The filter may be shaken by a push-button 37 enclosed in a hinged hood 39 which on lifting allows direct air flow to the fan and destroys the vacuum in the container. Pivoted clips secure the cover to projections 51, 52 on the ends of the container. A switch device comprising a starting resistance is provided. Pressure on a sliding bar first opens one switch and puts the resistance in circuit and then, through a second sliding bar interlocked with the first, closes a second switch completing the circuit. Release of pressure closes the first switch, cutting the resistance out.

Title: Heatproof insulating material
Inventor: SCHRAENKLER FRIEDRICH WILHELM
IPC: C08L69/00
Filed: 1961-01-31
Abstract: Silicone rubbers are produced by copolymerizing an organosiloxane with an organic polycarbonate of the formula: <FORM:0944028/C3/1> where n is in the range 10 to 17, by means of a  di-t-alkyl peroxide catalyst which is only active at temperatures above 150 DEG C.  By the addition of inhibitors and softeners the breakdown temperature of the peroxide can be made to approximate to the softening point of the polycarbonate.  A peroxide (e.g. benzoyl peroxide) with a breakdown temperature below 150 DEG C. may be incorporated to partially cross link the organosiloxane before it is copolymerized with the polycarbonate.  In the example a silicone rubber is prepared from an unpolymerized methyl siloxane, a polycarbonate of the above formula (n=15) di-t-butyl peroxide, henzoyl peroxide, a mineral oil plasticizer having a high naphthalene content, hydroquinone (an inhibitor) and kaolin.

Regulating.-Levers 32 on the same shaft as the rocker 25 are formed with extensions 33 en. gaging a slotted tube 34, which may be rotated by means of a handle 35 to open the main valves for starting. The handle 35 may be automatically depressed and released on the actuation of the switch of an electric starting-set, in which case the handle may be spring-loaded so that, on the first explosion, the valves 23 are closed by the motive fluid and the handle and starting-switch returned.
