Title: Improvements in or relating to air conditioning apparatus
IPC: F24F6/04
Filed: 1960-07-26
Abstract: 953,467. Air humidifiers. F. A. CATT, and J. A. CATT. Oct. 26, 1961 [July 26, 1960], No. 25997/60. Heading B1R. An air-conditioning apparatus comprises a casing 10 having an air inlet 16 and an air outlet separated from one another by water absorbent and air permeable material 24, means 14 for promoting a flow of air from the inlet through the absorbent material to the outlet and means for feeding water to the absorbent material which means are controlled by means responsive to the quantity of water present in the material. The control means is preferably provided by supporting the absorbent material 24 by a weighing mechanism, e.g. springs 18, a moving part of which controls a valve 27 in the water supply pipe 26. The degree of humidification of the air may be varied by adjusting the stiffness of the springs 18. The flow of air is promoted by a motor-driven air impeller 14 and may be varied by a means responsive to the amount of water in the air, e.g. a hygrostat 32, which means controls the speed of the motor. The hygrostat may comprise a sheet of material of conical shape which expands and contracts according to the moisture content of the air. The absorbent material may be one or more layers of cotton towelling supported on a rustproof wire mesh, and may be bent into zig-zag formation and supported in trays 17 supported one above the other. An electric heating element : may be arranged in the air stream.

Title: Improvements in sheet feed mechanism
IPC: B65H9/14
Filed: 1928-09-11
Abstract: 306,372. Ehrig, H., and Keilhauer, U. Sept. 11, 1928. Sheet-registering devices.-In a sheet-feeding- device of the kind in which conveying bands or rollers are driven at variable speed by elliptical gears designed to slow down the sheets as they approach front stops, the period of rapid feed is lengthened and the slowing down period shortened by combining two rocking gear wheels m, m<1> with the elliptical gears b, b<1>. The gear b is fixed on the driving-shaft a, and gear b<1> is freely mounted on a shaft h and has fixed to it a gear g meshing with gear m. The gears m, m<1> mesh together, and are carried in a forked lever i oscillated by a cam d on shaft a engaging a roller k mounted at one end of the lever i. A gear m<11> fixed to gear m engages a gear n on a shaft fitted with a sprocket o geared by a chain to a shaft r geared to the driving-pulley t of the feed belts v. The cam d is so positioned that, shortly before the front edge of the sheet reaches the registering- stops, the lever i is rocked so that the wheels m roll on the wheel g in the direction in which the wheel g is rotating, and the drive is retarded rapidly almost to zero. The lever is then rocked back by the cam so that the wheel m rolls in the opposite direction on the wheel g and effects rapid acceleration.

Filed: 1954-09-14
Abstract: 811,840. Propelling aircraft. MINISTER OF SUPPLY. Sept. 8, 1955 [Sept. 14, 1954], No. 26576/54. Class 4. [Also in Group XXVI] An aircraft powered by a gas turbine jet propulsion engine, the exhaust gases from which are discharged rearwardly through a jet pipe as a propulsive jet stream for normal forward flight, is provided with a fan mounted with its axis vertical, the fan drawing in air from atmosphere and discharging an air stream downwardly so as to produce an upward component of thrust on the aircraft, and means operable at will for diverting the exhaust gases from the jet pipe to drive the fan. The delta wing aircraft shown in Fig. 1 is powered by a gas turbine jet propulsion engine 3 which discharges exhaust gases as a propulsive jet stream through a jet pipe 5. An intermediate pipe 5a between the engine and the jet pipe is connected with two branch pipes 7 and is provided with a valve (not shown) which allows any desired proportion of the exhaust gases to be diverted into the branch pipes. The aircraft is provided with two fans, one in each wing, which rotate in opposite directions to balance out gyroscopic effects. As shown in Fig. 2, each fan rotor 12 comprises rotor blades 12b, a shroud ring 12c connecting the tips of the rotor blades, and a row of axial flow turbine rotor blades 12d mounted on the outer surface of the shroud ring. Exhaust gases diverted through the hand pipes 7 are supplied to these turbine rotor blades through a turbine inlet volute 13 which has a downwardly facing outlet provided with turbine nozzle vanes 14 co-operating with the turbine rotor blades 12d. Rows of stator blades 19, 20 are provided above and below the fan rotor blades 12b, and these blades may be adjustable to enable the vertical lift to be varied ; the pitch of the fan rotor blades may also be variable. Control of the aircraft may be effected by differential control of the blading of the two fans ; alternatively or in addition the turbine nozzle vanes 14 may be adjustable. The inlets and outlets of the fans may communicate with the atmosphere through apertures in the wings which may be opened or closed by pivoted vanes 21, 22 which may be operated differentially to control the aircraft. Alternatively the inlets may be connected to one or more boundary layer suction openings in the surface of the aircraft. Additional fans 23, 24 may be mounted in the wing tips and nose of the aircraft to control the aircraft, these fans being driven by compressed air bled off from the compressor of the engine 3. Specifications 730,585 and 733,931 are referred to.
Patent GB-696027-A (GB)
Title: Improved manufacture of odourless soaps from low-grade oils
IPC: C11D13/04
Filed: 1949-10-19
Abstract: Odourless soap is manufactured continuously from low-grade animal or vegetable oils and fats by treating the fatty acids thereof obtained by the Twitchell splitting process with molten alkali at about 300 DEG C (280 DEG -335 DEG C), in the absence of water, at substantially atmospheric pressure, and in the presence of about 40 per cent of sperm oil.  The sperm oil may be replaced by wool grease.  The sperm oil or wool grease moderates the violence of the reaction.  The reaction depends on the conversion of the bad-smelling unsaturated acids of the low-grade oils and fats, such as fish oil, into saturated fatty acids of lower carbon content.  The mixture of fatty acids and sperm oil, at a temperature slightly above the reacting point, and the molten alkali are passed at the same time into the saponifier, where they react at a temperature of about 300 DEG C. The reaction is instantaneous, hydrogen being liberated, and the soap is removed continuously.  A water seal maintains a slight pressure in the whole system so as to prevent the entrance of air.  An even temperature is maintained with a small fuel oil burner.  The process results in a simultaneous saponification and deodorization in one continuous process.  Specifications 145,502, 172,250, [both in Class 91], and 696,050 are referred to.

[Also in Groups XVII and XXX] Multiple-length filter tip or other mouthpiece stubs are fed one after another transversely of their lengths, as from a hopper 2, Fig. 1, and by a fluted drum 1, to means such as knives 3 which subdivide them into double-length stubs used in making up cigarettes, the resultant rows of divided pieces being first separated as by transference to a further fluted drum 4 having a shroud 5 with diverging stub guide channels 7, Fig. 5, and then fed by means such as screw conveyers 9 into containers 10. The tip 6 of the shroud 5 transfers the stubs from the drum 1 to the drum 4. Each conveyer 9 co-acts with a vertical feed channel 8 to which the respective guide channel 7 delivers stubs, the bottom portion of the channel 8 being formed as a spring pawl 16, Fig. 6, so as to swing back under excess pressure due to two stubs entering one conveyer tooth recess, and allow one of the stubs to be carried on by the drum 4 for subsequent ejection therefrom. The stubs pass upwards into each container 10, which is in the form of a box having a width just sufficient to accommodate the stubs lengthwise and provided with a removable lid 14, through a passage 11, springs or brushes 12 acting as a non-return valve. Each container 10 is provided with a paper web 13, passing round retractible pins 15 and out of the sides of the container, by means of which the stubs can be later extracted from the filled container when this has been removed and placed upright.
