Abstract: 1,064,742. Motor cycles. K. G. ENGINEERING LABORATORIES Ltd. May 8, 1964 [Feb. 8, 1963], No. 5166/63. Heading B7H. [Also in Division F2] An electric motor and a storage battery are mounted below the bottom bracket of a bicycle or tricycle, the motor driving the rear wheel through a chain-and-sprocket drive and a three-speed gear in the wheel hub. A gear change device comprises a hand- or footoperated lever 4 one end of which is constrained to move in a gate 5 having longitudinal slots 5a and 5b and transverse slots 5c, 5d and 5e defining the positions of the lever for each of the three ratios of the gear. A pinion 8 having a uni-directional detent 9 is mounted on the lever and co-operates with racks 6 and 7 adjacent the slots 5a and 5b so that the lever can only be moved in the slot 5a from a higher gear ratio to a lower ratio and in the slot 5b from a lower ratio to a higher ratio (in the direction of the arrows 10). A spring 12 normally urges the lever 4 towards the slot 5b in which is located a switch 11 in the motor circuit which, when closed, energizes the motor. When starting from rest, in a high gear ratio, the end of lever 4 is in slot 5b opposite slot 5c, and to move to the next lower ratio, is moved along slots 5c, 5a and 5b. While the end of lever 4 is out of the slot 5b, the switch 11 opens to de-energize the motor to facilitate the gear change. While changing from a low ratio to a higher one, the end of lever 4 remains in slot 5b so that the motor tends to accelerate during the gear change. An additional foot-operated switch is included for energizing the motor and operating a parking brake. The gear lever and gate mechanism may be provided with a keyoperated lock to maintain the lever in a position in which the switch is open. When applied to a bicycle a pair of retractable stabilizing wheels may be included on the vehicle.

Title: Process and apparatus for the manufacture of compost
IPC: C05F17/02
Filed: 1963-02-08
Abstract: In a process for the manufacture of compost from organic refuse by decomposition in a container, different parts of a mass of organic refuse in a container are successively brought into contact with warm, moist air to effect aeration of said parts, the parts are then embedded in the mass of the refuse for decomposition therein under anaerobic conditions, and the cycle is repeated, so that parts of the refuse are submitted repetitively to decomposition under aerobic and anaerobic conditions, the time during which a part is being decomposed under anaerobic conditions being longer than it is in contact with the warm moist air.  The warm, moist air may be an airstream mixture at 40-60 DEG  C.  The transfer of refuse may be effected in a horizontal rotating drum having at least one closable opening for filling and emptying the drum, inlet means independent of the rotation of the drum for admitting warm, moist air in the drum above the refuse therein, and an air outlet.  In one embodiment (Figs. 1 and 2), organic refuse is carried by conveyer 10 to closable opening 11 on wooden drum 1.  The drum is rotated by the engagement of driven chain 5 with teeth 4 on encircling steel rings 3. Air or air-steam from source 31 is admitted by pipe 15 into the free space above the refuse in the drum.  The surface of the refuse 14 is inclined due to the drum's rotation.  Air is exhausted through openings 16 in the other end of the drum.  The openings are covered by swivelling spring-loaded flaps 17 which are arranged to open as successive openings 16 come opposite the free space in the drum. Longitudinal bars 22 aid movement of material inside the drum.  The continual or intermittent replacement of the surface layer of material ensures that successive portions of the refuse are subjected to aerobic fermentation while the remainder undergoes anaerobic fermentation. The drum is emptied from closable openings 12 no to conveyer 13. In a further embodiment (Figs. 5 and 6) air is supplied by U-shaped pipe 24, the holes 25 in which are protected by shield 26.  The air outlet comprises pipe 28 provided with holes 29.  The material may be treated, before or after decomposition, with hot or superheated steam.  After decomposition, the material is screened and is preferably subjected to further ripening in sacks or silos, either airtight or provided with an air supply. <PICT:1005078/C1/1>

Title: Thermionic valves
IPC: H01J21/18
Filed: 1921-02-16
Abstract: 180,405. Jackson, W. J. Mellersh-, (Soc. des Etablissements Gaumont). Feb. 16, 1921. Vacuum tubes.-A number of anodes arranged around an incandescent cathode are connected singly or in groups with receivers, the electron flow with anodes being controlled by a magnetic field acting transversely to the path of the electrons. As shown, two pairs of flat anodes a<1>, a<3> and a<2>, a<4> are connected through two receivers r<1>, r<2> with a source of current p, the arrangement of the anodes being such that a magnetic field, parallel with the filament cathode f, produces an unequal distribution of electrons between the anodes, so that the electron flow to the anodes a<1>, a<3> is increased, and the electron flow to the anodes a<2>, a<4> diminished, with consequent difference in the currents in the receivers, the total current in the receivers remaining constant. The magnetic field may be constant or variable. An auxiliary controlling electrode may be interposed between the cathode and the anodes. If the strength of the magnetic field is increased to a critical value, the current diminishes suddenly owing to the deflection of electrons from the anodes. With a further increase in the strength of the magnetic field, ionization by collision may be produced, with a resultant increase in the current. The valve may contain gas having a low ionization potential, such as neon or mercury vapour at a pressure of 0.01 to 0.1 mm., or 1 cm. of mercury. The valve may be used in arrangements of amplifiers, relays, detectors, impedances and circuit closers or breakers.

Abstract: 511,542. Lead chromate pigments. DU PONT DE NEMOURS & CO., E. I. Feb. 21, 1938, No. 5480. Convention date, Feb. 20, 1937. [Classes 1 (iii) and 95] Pigments comprising lead chromate which may also contain lead sulphate or iron blue are treated in suspension, preferably immediately after precipitation and in a medium maintained at a pH value of 4.5-6.5, with one or more reducing agents consisting of soluble metal or ammonium sulphides or polysulphides, or soluble stannous salts. So much reducing agent, for instance 4 per cent. with reference to the chromate, is used that no substantial reduction of the chromate takes place. The products have improved light fastness and are of small particle size ; additions such as tannic acid, tartaric acid, or disodium phosphate to control particle size during precipitation, or precipitation upon the pigment of hydroxides of aluminium, zinc, or tetravalent tin to improve light fastness are therefore unnecessary. Numerous examples of operation are given.

Abstract: 1464782 Power-assisted steering mechanism DANFOSS AS 6 Feb 1974 [7 Feb 1973] 05555/74 Heading B7H [Also in Division G3]  In a hydrostatic steering system having a steering motor 1 supplied both from a reversible control circuit including a pump 7 and a control unit 5 with a metering device and from a reversible power circuit including a pump 13, the supply sides of control and power circuits supply the cylinder 1 through respective throttle valves 123, 128 and 133, 138 the opening of which stands in a predetermined relationship to the pressure difference thereacross, and a combined reversing and pressure comparator valve 116 maintains the pressure upstream of the power circuit throttle valve 133, 138 in proportion to the pressure upstream the corresponding control circuit throttle valve 123, 128 so that the quantity of fluid supplied to the motor 1 from the power circuit is a fixed multiple of that supplied from the control circuit. When the control unit 5 is actuated fluid is directed into one of control passages 10, 11, passage 11 as shown, so that the associated throttle valve 128 is opened against spring-loading 129 and the pressure developed in the passage 11 acts through a two-part pin 180, 181 on the spool 150 of the reversing and pressure comparator valve 116. Resultant movement of the spool 150 directs fluid supplied by the pump 13 through a non-return valve 15 into a passage 20 upstream of the power circuit throttle valve 138. The pressure in the passage 20 acts through a passage 175 on a pressure face 158 in the spool 150 to balance the pressure acting through the pin 180, 181 so that the pressure in the passage 20 is equalized with that in the passage 11. Each control circuit and power circult throttle valve 123, 128 and 133, 138 has respectively two and twenty tapering triangularsection throttle slots 168 which are increasingly uncovered as the valve opens, and each throttle valve is subjected to the pressure downstream thereof through passages 169, 170, 171, 172. When the control unit 5 is not actuated the closed throttle valves block movement of fluid to and from the motor 1, the throttle valves in the return side being opened in response to pressure on the supply side by respective pistons 127, 132, 137, 142 subjected to supply side pressure through pilot passages 145, 146 including restrictions 147, 148. 'The control-circuit throttle valves may have additional blocking valves, Fig. 5 (not shown), which open before the throttle slots are uncovered. In another embodiment, Fig. 1 (not shown), a non-return valve is connected in parallel with each throttle valve, and the spool of the reversing and pressure comparator valve has two end faces each of which can be subjected through respective non-return valves to the pressures upstream of the power circuit and control circuit throttle valves.
