Title: Position control system using magnetic force
IPC: H02K41/02
Filed: 1973-03-27
Abstract: 1424413 Automatic control of position HANDOTAI KENKYO SHINKOKAI 27 March 1973 [27 March 1972] 14540/73 Heading G3N [Also in Division H1] An object 1, e.g. a mark of a photo-etching or evaporative deposition apparatus, is positioned by an electromagnet 27 acting on magnetic material attached to the object, the force between them being opposed by springs 4a, 4b. As shown, an interferometer 32 in combination with a prism on the object produces a position signal which is converted into pulses and fed to a reversible counter 34 taking into account the polarity of the signal. The count is then stored in a register 35 for comparison with the count in a register 21 representing the desired position. The output signal from a comparator 22 representing the difference between actual and desired positions produces pulse signals to drive a stepping motor 29 (as auxiliary electromagnet) giving coarse control until the difference signal is reduced to a predetermined valve which is converted to an analogue signal. This signal is use to precisely control the electromagnet 7 by means of a PID control circuit 25 which also receives a speed signal from a detector 30 via a logic circuit 31 to accelerate positioning of the object. This system can be applied to two or three axis control, arrangements of electromagnets being disclosed [see Division HI ].

Title: Improvements in or connected with wadding
IPC: A61L15/28
Filed: 1926-06-10
Abstract: 265,125. Papeteries de la Robertsau. Jan. 29, 1926, [Convention date]. Bandages. - Non hydrophile or hydrofuge (water repellent or non absorbent) cellulose wadding is made by wet sizing a cellulose paste and converting the sized paste into wadding. The cellulose paste may be made according to the methods used for preparing ordinary hydrophilecellulose wadding and be treated similarly to the manner in which paste is treated in making ordinary sized paper. Thus the cellulose paste is sized in the hollanders with milk of glue (resinate of soda, or soap of soda resin). The refined paste is then passed into the feed water tub of the wadding machine, aluminium sulphate being first added in some cases. Dextrin or starch made soluble by an alkali may be added in the hollanders. The resin soap or starch may be replaced by gelatine precipitated by formaldehyde. The hydrophobe wadding may be combined with hydrophile wadding by superposing layers of the respective waddings, and the product may be used in making cloths, napkins and towels for children &c. A layer of hydrophobe wadding may be inserted between two layers of hydrophile wadding. According to the Specification as open to inspection under Sect. 91 (3 ) (a), the wadding may be made by impregnating ordinary cellulose wadding with water-repellent substances such as a solution of paraffin wax in a light hydrocarbon, or by covering or transforming the surface of the wadding so as to be impermeable or hydrofuge. This subject-matter does not occur in the Specification as accepted.

Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: GENESTIN PAUL
IPC: F02M19/12
Filed: 1917-10-16
Abstract: 118,831. Genestin, P. Aug. 31, 1917, [Convention date]. Addition to 109,784. Spray carburettors.- The parent Specification describes a carburettor in which the area of the passage around the nozzle is varied by hinged flaps actuated by a spring- loaded piston subjected to the suction in the induction pipe between the throttle valve and the engine, the throttle valve being provided with cam-surfaces which, in certain positions of the valve, prevent movement of the piston and flaps. The invention consists in replacing the flaps by a cone and in modifying the cam-surfaces on the throttle valve. The nozzle 13 is fixed and forms a guide for a piston 8 which carries a cone 11, is loaded by a spring 9, is subject to suction through a passage 10, and carries a rod 19 provided with a head 20, Figs. 2 and 3. The throttle-actuating lever 3 has a slot 21 in which is adapted to slide a block 22 loaded by an adjustable spring 23 and carrying a cam 25. The throttle is shown in the closed position in Fig. 3, and the cam 25 is then clear of the head 20. As the throttle is opened, the cam comes under the head 20, and the piston 8 is subjected to the action of the spring 23 as well as that of the spring 9. A cam 26 on the throttle limits the upward movement of the piston 8 and therefore the minimum area of the air passage 18 around the cone 11. Stops 31, 32, Fig. 3, limit the movement of the throttle. Air is admitted to the cone 11 and space 18 through apertures in the casing and apertures 17 respectively. When the throttle is nearly closed, the plate 27 cuts off the passage 10 from the suction; when completely closed, a port 29 again opens up the passage 10; a longer port in the plate 27 keeps the passage 10 open for the remaining positions of the throttle valve.

Abstract: 558,374. Testing indicating-instruments. FIELD AIRCRAFT INSTRUMENTS & EQUIPMENT, Ltd., and THOMAS, A. H. J. Oct. 30, 1942, No. 15319. [Class 106 (iv)] [Also in Group XX] An apparatus for use in testing gyroscopic instruments comprising an instrument-carrying frame and separate means for rocking the frame about each of three axes at right angles to one another so that the instruments may be subjected to rolling, pitching and yawing motions independently or to any combination thereof. The instruments are secured to a twelve-sided frame 1 attached to a support 4 carried on a Hooke's joint at the top of a vertical spindle 6 which may be rotated continuously by a belt 74 or may alternatively be oscillated by engaging two dogs 60, 61 to impart yawing motion to the frame. The amplitude of the yawing movements may be varied. Rolling and pitching movements are imparted to the frame by the sliding movements of a tubular member 13 provided with a partspherical head 12. The tubular member is movable horizontally in any direction and is actuated by two separate adjustable-throw cranks operating in two directions at right angles. The adjustable throws permitting the amplitude of the rolling and pitching motions may be separately varied or either of them, or both, suppressed. The vertical spindle 6 is hollow to provide an air duct connecting the instruments with a pump 92 which places the instruments under a partial vacuum during testing. In testing the instruments, an initial reading thereof is taken whilst the frame 1 is horizontal and a second reading is taken after the testing movements. If the frame 1 stops out of the horizontal it may be quickly brought to the horizontal by pulling out and then turning a hand-lever. A reverse movement of the hand-lever restores the parts in readiness to start a further testing operation.
