Abstract: 338,159. Triggs, W. W., (Buckeye Incubator Co.). Aug. 7, 1929. Ventilating brooders.-A brooder is provided with means for continuously recirculating the major portion of the air through the chicken chamber, means for supplying fresh air and exhausting foul air in substantially equal proportions, means for adjusting the temperature of the air and means for causing a general diffusion of the air upwardly through the chicken chamber. Brooder trays 16 are arranged in tiers 17 with aisles 18 between, partitions 25 that do not extend to the floor being arranged at the sides of the tiers. A steam or hot water plant 11 arranged in an ante-chamber 10 supplies heating fluid to coils 13 arranged in housings along the side walls of the house. Fresh air is admitted at the upper side of the coils 13 through ducts 20, some of which are provided with dampers 22, the air thus admitted entering the housings and mixing with circulating air that enters through passages 37, the mixed and heated air then being directed by fans 24 to the bottom of the chamber whence it diffuses through the brooder cages. Some of the air reaching the top of the brooding chamber passes into a chamber 27 through openings 28, some of which are provided with dampers 29. The foul air entering the chamber escapes through a pipe 32, an exhaust fan 33 being provided to accelerate such escape. The outlet pipe 32 is provided with a controlling damper 34 which, however, is never completely closed, thus permitting at all times ventilation of the brooder house. The damper 34 and the dampers 22 are coupled together and are actuated simultaneously by a motor 40 that is thrown into operation by a thermostat 38. A perforated pipe is connected to one of the coils 13 to allow steam to enter the housing 14 to humidify the air therein.

Title: Rotating piston engines,pumps and compressors
IPC: F02B53/00
Filed: 1964-06-10
Abstract: 1,062,659. Rotary-piston engines. F. JERNAES. June 10, 1964 [Nov. 1, 1963; April 10, 1964], No.24149/64. Heading F1F. In a rotary-piston engine, pump or compressor of the n and n + 1 lobe type the planetary motion of the piston (5), Figs. and 2 (not shown), relative to a stationary casing (1) is controlled by a gear system comprising two sets of 'planet' gear-wheels (7) rotatably mounted on discs (9) attached to a power-output, or driving, shaft (13) on either side of the piston, said gear-wheels being in mesh with a pair of internally-toothed 'sun' gear-wheels (9) fixed to end walls (16) of the casing. Each of the gear-wheels (7) is coupled to the piston by a stub shaft (6), which is integral with the gearwheel and eccentric relative to its axis of rotation. The piston engages with spring-loaded radial seals (11) in the casing and carries a pair of discs (14) constituting end closures for the working chambers (3,4,5). The axially-innermost surfaces of the discs (14) engage with axial seals (15) in the peripheral wall of the casing. When the engine operates as an I.C. engine, arcuate ports (21) are formed in each disc (14), these ports being periodically in register with an inlet pipe and an outlet pipe, respectively, in the end walls (16) and a recess (23) in each lobe of the inner peripheral surface of the casing. Alternatively, the 'panet' gear-wheels may be arranged to mesh with an externally-toothed 'sun' gear-wheel; and the piston may be fixed whereas the casing is rotatable. Modifications of the piston and casing are described, Figs. 8,9 and 10 (not shown), wherein the piston has either two or three lobes and either a substantially elliptical or triangular profile accordingly, the casing having three or two lobes correspondingly. The engine may be adapted to be driven by steam or a hydraulic fluid.

Patent GB-693582-A (GB)
Title: Hydrogenation of powdered carbonaceous material such as coal
IPC: C10G1/08
Filed: 1950-10-06
Abstract: <PICT:0693582/III/1> Powdered coal or other carbonaceous material is hydrogenated in the fluidized state to give gas oils and other oils at a temperature of about 700-1050 DEG F and a pressure of 1,000-10,000 pounds per square inch in a reactor 4 into which a stream of hydrogen-containing gas is fed upwards from line 5 at a sufficient velocity to fluidize the powdered material.  Unused hydrogen and hydrocarbon vapours are taken off at 8, after separation from entrained solid material by cyclones 7, cooled at 10 and gases and vapours separated from condensed material at 11. The powdered material is fed to the reactor from a lockhopper 1 via a stand pipe 2 into which fluidizing gas is admitted at t.  To prevent agglomeration by agglutinants formed when the coal or other material becomes plastic a powdered material adapted to absorb such agglutinants is also fed to the reaction zone.  This may be clay, sand, crushed rock, brick dust or preferably solid partially hydrogenated carbonaceous residue which as shown is withdrawn at 14 from the reactor 4 and returned by fluidizing hydrogen from line 15 to the hopper 1 for mixing with the feed. Unreacted hydrogen is recycled via line 13 and fed, together with hydrogen from line 5, by pump 17 to the reactor via heater 6.  A portion of the gas in line 13 may be vented at 16. Hydrogenated coal not required as diluent is withdrawn at 18.  The Specification lists suitable hydrogenation catalysts which may be applied to the coal as a solution or suspension.  A cracking catalyst may be included.  In an example Pittsburgh seam coal ground to size 200-400 mesh and mixed with an equal weight of partially hydrogenated coal was sprayed with an aqueous solution of tin chloride and hydrogenated at 800 DEG F and 200-350 atmospheres pressure with an excess of hydrogen, i.e. from 5-25 cubic feet (at standard temperature and pressure) per pound of coal.  The reaction time was from 1-2 hours.  An oil yield of 54 per cent of the weight of coal and containing gasoline and gas oil was obtained.  The use of a silica-alumina cracking catalyst, slurried with the tin chloride solution, to improve the octane rating of the gasoline is referred to.

Abstract: 205,079. Aktiebolaget Ljungstr÷ms Angturbin. Oct. 3, 1922. [Convention date]. Reversing-gearing, suitable for locomotives, of the kind in which toothed wheels are moved in their own planes into mesh, is provided with an auxiliary rotary motor for turning the countershaft so as to bring the wheels that are to be meshed into proper position for interengagement. A shaft 1, Fig. 1, drives a shaft 3 through constant mesh gearing. A shaft 4 driven from the shaft 3 preferably by a constant-mesh pair is eccentrically mounted so that it can be moved to bring a gear 4<1> into mesh with a gear 6<1> on a driven shaft 6 for forward driving. For reversed driving, connection is effected through gears on an eccentrically-mounted idle shaft 5. The eccentric mountings of the shafts 4, 5 may be operated through links 7, 9 from oil-actuated pistons 8, 19 controlled by a lever 26. The auxiliary rotary motor is preferably a Pelton-wheel 21, Fig. 2, connected through gearing 22 and a clutch 24 with the shaft 1, the whole being within a casing 20. Oil for driving the motor 21 arrives through a duct 28 being controlled by the same lever 26. A third piston 10 operates a sector 13 for locking the reversing-gearing, and pointers upon an indicator 14 show the position of the reverse controlling eccentrics. The proper engaging of the gear teeth is effected by trial with the lever 26.

Title: Improvements in or relating to alternating current amperehour meters
IPC: G01R11/36
Filed: 1929-08-12
Abstract: 333,395. Sandison, A. G. S. Aug. 12, 1929. Supply meters having a driving-system comprising a potential magnet 3 and a current magnet 6 are adapted to register ampere-hours by providing the braking torque partly by means of a constant magnetic field produced for example by a permanent magnet 11 and partly by a magnetic field varying with the voltage, produced for example by a shunt-excited electromagnet 9, or by arranging the potential magnet 3 so that sufficient field passes through the disc 1. The torques due to the permanent magnet 11 and the electromagnet 9 are adjusted to be equal when the voltage is at its normal value. The electro magnet 9 produces a braking torque proportional to the square of the voltage, and therefore for a small change in voltage the proportional change in the torque is approximately double the proportional change in the voltage. Consequently the total braking torque varies in proportion to the voltage for small changes thereof, i.e. the driving and braking torques vary in the same proportion and the instrument registers amperehours. The current integrated may be that, flowing through a resistance 8 which is automatically varied so as to produce a current proportional to a function which it is desired to integrate. In order to neutralize changes of phase angle as the resistance 8 is varied, a condenser 12 shunted by an adjustable resistance 13 may be included in the circuit.
