Title: An improved weather forecasting apparatus
Filed: 1938-04-26
Abstract: 501,387. Meteorological instruments. INGENHOF, J. April 26, 1938, No. 12457. Convention date, April 26, 1937. [Class 97 (iii)] An air-filled cylinder 9 sealed at its lower end communicates at its upper end with a belt 10. The cylinder 9 and bell 10 are arranged in a glass tube 1 containing liquid and open at its upper end. An outer cylinder 7 having a slot 8 is interposed between the bell 10 and tube 1 so as to form a pair of capillary spaces. As shown, the cylinder 9 and bell 10 are suspended from a pulley 15 on a spindle 16 carrying a larger pulley 18 which is connected by a cord 24 to a pointer moving over a scale (not shown). The position of the tube 1 may be adjusted by the screw 21. A pointer 29 on an endless band 32 may be adjusted to the levels of the liquid by a handwheel 34. Variations in the volume of the air in the cylinder 9, due in particular to variations in temperature, cause variations in the levels of the liquid and enable the weather to be forecast from the relative movements of the liquid in the capillary space between the tube 1 and cylinder 10 and in the slot 8. In a modification the cylinders 7, 9, and the bell 10 form a unit with a cap against which the tube 1 may be pressed by an outer casing.

Title: Improvements in and relating to electric motors
IPC: H02K23/02
Filed: 1928-03-09
Abstract: 313,429. Fletcher, G. H., Brooks, R., and Associated Electrical Industries, Ltd. March 9, 1928. Exciting; motors, controlling.-A multipolar motor is provided with a fixed winding in sections comprising radially inner or front and outer or back coils, these being so connected in sectional circuits that one circuit includes the front coils on the North poles and the back coils on the South poles while the other circuit includes the back coils on the North poles and the front coils on the South poles, thus giving balanced magnetic conditions when the circuits are connected either in series or parallel or are arranged to give weakened field conditions. Figs. 1 and 2 show a balanced arrangement of tapped coils for a motor having four poles N1, N3, S2, S4 with inter-poles (similarly designated) having separate windings brought out to terminals A +, A1. The two sections of the main coils are brought to terminals + 1, FF1 - and + 2, FF2 - . The taps are brought out at WF1 -,. WF2 - and are not employed in the case of series regenerative working. With parallel connection for motoring, giving full field strength, the circuit from + 1 to FF1 - includes a radially outer or back coil on each of the vertical poles N1, N3 and an inner or front coil on each of the horizontal poles S2, S4. Similarly, the circuit from + 2 to FF2 - includes back and front coils on the horizontal and vertical poles respectively, so that. magnetic balance is obtained. Similarly, when the, taps are used wih a resistance in series. with a part only of each section of the windings, giving minimum field strength, the circuits are from + 1 to WF - and from + 2 to WF2 -, i.e. back coils on all poles are used. With the connections arranged to give full current in the back coils and reduced current in the front coils which are shunted by resistances, thus giving an intermediate field strength, a magnetic balance is still obtained in the groups although there may be differences in the leakage conditions of the front and back coils. The Provisional Specification describes the use of 3-section drum switches in combination with the regenerating drum of a master controller in a regenerative traction equipment or changing the section connections from series to parallel. Specifications 306,726, 312,715; and 313,427, [Class 38 (iii), Electric motor control systems &c.], are referred to.

Filed: 1917-09-11
Abstract: 119,672. Soc. Lorraine des Anciens Etablissements de Dietrich et Cie de Luneville. Sept. 30, 1916, [Convention date]. Magnetos, driving.-In driving two magnetos for the double ignition of the cylinders of internalcombustion engines, the pinions of the magnetos are rotated from the engine by means of a toothed wheel F which is keyed on a sleeve E rotating on independent ball bearings, and is connected to the engine crank-shaft A through an elastic coupling; by this arrangement, deflections of the crank-shaft and shocks are not transmitted to the magnetos. As shown, the shaft A has a forked head B in which a laminated spring C is fixed. The ends of the spring enter two recesses in the sleeve E. In a modification, the wheel is not keyed upon the sleeve, but is driven by another sleeve connected to the first sleeve by helical keys; the time of sparking may be varied by axial displacement of the second sleeve.

IPC: H01J31/26
Filed: 1949-05-17
Abstract: 679,719. Local viewing arrangements. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 17, 1950 [May 17, 1949], No. 13069/49. Addition to 677,983. Class 40 (iii). [Also in Group XL (c). Means for providing a prolonged presentation of information, such as a radar plan position indication, displayed of a cathode-ray tube comprises means for producing a charge image in response to the original signals, means for scanning the charge image a plurality of times to derive signals therefrom, means for employing the signals, derived from each scan to produce or renew a further charge image and means for scanning said further charge image a number of times to derive further signals therefrom. The further signals may be used to give the required indication. The cathoderay tube indicator 1 of a radar system 9 may be arranged so that its display is optically projected on to the lower half of the storage element of a storage tube 3. The charge image produced is scanned by the tube's electron gun 7 and the signals fed through amplifier 11 and switch 12 to cathode-ray tube 2 to produce a corresponding optical image of high intensity which is projected on to the upper half of the mosaic of tube 3. Switch 12 is then operated, altering the bias on tube 3 by means of unit 14 so that the upper part of the mosaic is scanned and directing the output of amplifier 11 to final display tube 13. The scanning of the upper half of the mosaic is repeated to provide a longer and more constant image on tube 13 until the charge pattern begins to decay, then the switch 12 is manually or automatically operated to cause the beam to scan the lower half of the mosaic and renew the charge pattern on the upper half by means of tube 2. Instead of using the upper and lower halves of the mosaic in tube 3 alternately the storage elements of two separate tubes may be used.
