Title: Improvements in and connected with steam superheaters
IPC: F22G5/04
Filed: 1935-08-30
Abstract: 462,001. Steam. superheaters. BABCOCK & WILCOX, Ltd. (Babcock & Wilcox Co.) Aug. 30, 1935, No. 24217. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 2, 1936.] [Class 123 (iii)] The flow of furnace gases over a superheaert 10 placed between banks of boiler tubes 16, 18 is so controlled by dampers 44, 56, 57, 59 that the mass flow of the gases, that is the mass per unit area of flow passage, is varied in accordance with the boiler load or superheat to prevent excessive variations in the superheat. At light loads, all the dampers are closed, to cause the gases to flow over the superheater between baffles 40, 42 in three passes and with the highest mass flow and consequent highest heat transfer rate. At heavy loads, the dampers are opened to increase the gas flow area. The dampers may be operated in turn by diaphragm motors to which pressure fluid is supplied through passages in a pilot valve operated in accordance with the temperature in the superheater outlet header or with the fall in pressure through the superheater.

Title: Improvements in and relating to the treatment of road making materials
IPC: C08L95/00
Filed: 1930-08-13
Abstract: The coating or impregnation of road-making materials or road surfaces with hot tar, hot bitumen, cold solutions of tar or bitumen, or mixtures of these materials is aided by the use of pyridine bases in the substantial absence of oxy compounds of the aromatic series. According to one method, the road-making materials or the road surfaces are treated with tar or bitumen containing pyridine or one of its related azocyclic compounds in excess of that which is normally present therein.  The road-making materials may be treated in an agitating device.  The road surface, or the stones in the agitating device, may be first treated with pyridine bases or azocyclic compounds thereof prior to their treatment with tar or the like.  The pyridine or the related azocyclic compound may be in a relatively pure state, or crude or commercial products containing suchcompounds may be employed.  Under the term "pyridine bases" are included pyridine, picolines, lutidines, and the like, quiniline, quinaldine, acridin, or similar compounds.  According to the Provisional Specification, road surfaces or road-making materials are also treated with cold solutions of tar or bitumen containing pyridine, or one of its related azocylic compounds, or mixtures thereof.  Specifications numbered 355,937 and 356,003 are referred to.

Abstract: 634,961. Drive of parts of paper-making machines. MILLSPAUGH, Ltd., and HEYS, R. C. Dec. 27, 1947, No. 34300. [Class 96] Paper - making machine parts, e.g. a suction press roll 1, are driven from a common shaft 10 running longitudinally of the machine through continuously variablespeed transmissions, e.g. expanding cone and V-belt (with adjustment 52, 53 &c.) each driving a subsidiary shaft 13 parallel with the main shaft 10, and simple reduction gearing, e.g. a worm, and worm-wheel 16, for the machine part. The V-belts are tensioned by jockey pulleys 26 adjustable by hand-wheels 30 &c. Provision is made for removing packing from couplings, or spacers from supporting pedestals to facilitate replacement of the endless V-belts. A similar arrangement is described for a lower cylinder of a bank of dryer cylinders, an upper cylinder being driven by chain &c. from the-subsidiary shaft of the lower driven cylinder. All dryer cylinders may be likewise driven, or only the one upper and one lower, the remainder being driven by the pull of the felts. The arrangement is compact, and it avoids difficulties of alignment of shafts. The drive may be at the rear of the machine and may be controlled from the front through chain gear or through hydraulic, pneumatic, electric remote control or servo-mechanism.

The disc 1 is then inverted and an In pellet placed in a hole extending from what is not the upper face of the disc to the upper face of the wafer and reheating to form a second PN junction. Leads 16, 17 are then connected to the In blobs as described in Specification 774,800 and the device housed in an envelope through which leads 6, 16, 17 are sealed. By using all the holes 2 a number of units may be made simultaneously.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 22, 1934]. [Class 8 (ii)] [See also Group II] Ground material from a mill or storage chamber is sucked by a current of air into a multi-compartment receptacle and on entering the compartments one after another impinges on a deflector and is thrown in succession on to the upper portion of each compartment the material separated in each compartment falling to the lower portion which is closed by a valve. As shown air and ground material from a mill 38 is drawn through a pipe 40 to a sifter 1 mounted on trunnions 34 and divided into four compartments 6.... 9, Fig. 2, each provided with a removable conical bottom 26 closed at the end by a ball 29 manually operable by a lever 30 and cord 32. Each compartment is connected in series by adjustable openings 10 ... 12 which may be of the venetian blind type and which are progressively lower in each chamber toward the outlet. The last chamber 9 is divided by a screen 18, tapped by a member 45. The cover 21 may have a rubber joint 22. The air and ground material enters the chamber 6 at 36 and is deflected upwardly by a plate 42, it then passes through opening 10 and is again deflected upwardly. After passing in a similar manner through chambers 8, 9 the remaining dust in the air is caught on the screen 18 and the air is withdrawn through the pipe 41 connected to the suction pump 39. The heavy material is deposited according to grade in the various chambers and may be discharged into sacks attached to holders 44. Each chamber is provided with an inlet 36 so that certain chambers may be cut out as desired. Hot or cold air deficient in oxygen may carry the ground material into the sifter. The sifter may be used with a storage chamber, the material being conveyed into the sifter by an air blast. In a modification a receptacle 48, Fig. 4, is divided by a filter cloth 49 into a collecting and suction chamber 46, 47 respectively. Two inlet connections 50 and a suction connection 51 are provided. The receptacle 48 is connectible in series with the multi-compartment sifter described.

Title: Fuel cell electrode
IPC: C04B35/532
Filed: 1962-06-27
Abstract: A porous matrix for a catalytic fuel cell electrode is made by forming separate raw mixes of porous carbonaceous material and activated carbon, each with a liquid binder, shaping the separate raw mixer into thin flat bodies using a pressure in the range of 105 to 175 kg. per cm.2 gauge, and alternately superimposing layers of the porous carbonaceous material and activated carbon bodies to form a laminated composite body.  This body is recompressed using a pressure in the range stated above for a period to ensure the equilibrium of the binder and the intermingling of carbon particles throughout the several interfaces.  It is then subjected to baking in a non-oxidizing atmosphere at a temperature in the range of 150 DEG  to 250 DEG  C. for 12 to 24 hours, the temperature then being gradually raised over 1 to 2 hours to attain a temperature of 1000 DEG  C., at which temperature it is held for 30 to 90 minutes, before being allowed to cool at ambient temperature.  The activated carbon powder has a specific surface of 800-1000 m2/g.  The porous carbonaceous material may be powdered baked carbon having a bulk density of 10.5 g./cc., a porosity of 48% and an average pore diameter of 33 microns and/or powdered graphite having a bulk density of 1.05 g./cc., a porosity of 48%, and an average pore diameter of 140 microns.  The liquid binder may be a heavy residual hydrocarbon oil.  The porous matrix may be impregnated with catalytic material, e.g. one of the noble metals, e.g. platinum or palladium.
