Title: Electromagnetic thermometer
IPC: G01L1/12
Filed: 1957-10-11
Abstract: 848,238. Electric measuring systems. VYZKUMNY A ZKUSEBNI LETECKIJ USTAV. Oct. 11, 1957 [Oct. 11, 1956], No. 31821/57. Class 40 (1). In temperature-measuring apparatus, a ferromagnetic body is magnetized by A.C. and is subjected to torsional stress owing to the expansion of a member or a fluid exposed to the temperature to be measured, the consequent distortion of the magnetic field inducing a signal representative of the temperature in a pick-up coil wound on the body. As shown, Fig. 1, a cylindrical jacket 1, provided with helical slots 2, is disposed around a ferromagnetic body 3, being fixed thereto at both ends and in the middle. The jacket 1 and the body 3 have different co-efficients of thermal expansion, so that a temperature change causes the body to be twisted, distorting the field produced by a toroidal excitation winding 5 and generating an E.M.F. in pick-up coils 4. Fig. 2 depicts a device for measuring surface temperature in which a change of dimension of a base 6 transmits a torsional stress to a body 11 secured centrally to one end of the base 6 and at its ends to a casing 9, which is itself attached to the other end of the base. Parts of the device remote from the base are protected by thermal insulation 16. In the device shown in Fig. 4, the expansion or contraction of a rod 17 relative to its casing 18 is transmitted to a ferromagnetic body 22 via a rod 19 and a lever 21. To measure temperature at a relatively inaccessible point, the change in volume of a fluid 28, Fig. 5, in a vessel 27 subjected to the temperature operates, via a capillary tube 29 to modify the shape of a corrugated vessel 30, thus twisting a currentcarrying ferro-magnetic body 32 centrally fixed on the vessel 30 and wound in the form of a twostart helix and carrying a pick-up coil 33. In all embodiments, the exciting and pick-up circuits may be interchanged.

Abstract: 726,966. Bindings for loos e leaves. TRUSSELL, C. D. Dec. 18, 1952, No. 32139/52. Classes 16 and 146(1). A method of manufacturing mechanical bindings for loose leaves comprises : providing web material with ribs along opposite edges, forming slots in the sides of the ribs, severing the sheet material connecting the ribs into ring- forming fingers alternately connected with the respective ribs and of a width at the free ends to enter the slots in the ribs, the web material either being formed into an open tube or the fingers being given appropriate curvature. As shown in Figs. 1, 4 and 6 tubular stock with tubular ribs 20 is preformed as by extrusion or other methods from plastic material. The stock is then held flat or partially so and slots 23 formed close to the stock in the ribs 20 by circular saws. Dies 24 are then positioned opposite the slots 23 and punches 25 driven through slots 23 to form the slots 26 which may be shaped with an arched portion 27 and lug 28 as shown in Fig. 15. Punch and die members then operate on the flat stock to cut out the blanks shown in Fig. 6 to form fingers 21 having locking slots 29 for co-operation with the lugs 28. As shown in Figs. 12 and 15, flat stock 32 is first punched along the edges with slots 26 and the edges then rolled to form tubular ribs 200. The stock is then punched as in Fig. 6 to form the fingers 21 with slots 29 and the fingers 21 then curled to give the set shown in Fig. 15, the curling being either to bias them past the fully closed position for a self closing type of binder or as shown, when the rings have to be closed by force.

Title: Improvements in and relating to variable pitch propellers
IPC: B64C11/42
Filed: 1938-11-07
Abstract: 522,249. Variable-pitch propellers. ALGARSSON, G. Nov. 7, 1938, Nos. 32243 and 32244. Convention dates, Nov. 15, 1937, and Aug. 12, 1938. [Class 114] The aerodynamic and other forces acting on the blades are approximately balanced by counterweights, the blades being connected for pitch changing movement to a statically mounted fluid pressure device associated with the driving member, wherein the torque produced by the device is controlled both in magnitude and direction to effect change of pitch. Weights 137 attached to the crown wheels 134 balance the natural turning moments of the blades. A torque is applied to the crown wheels by a gear train to which a reactive torque in either direction can be applied by the air pumps 158, 168. The effect of these pumps is controlled by the governor operated valve 173, 175 to maintain a constant speed. In modifications the pump can act as an air motor, or one pump only is used for control. In another modification, the fluid pumped is liquid. The centrifugal forces from the blades are transmitted between them by links 130 and bearings 126 and thus do not fall on the hub casing. The ball bearings 131 can be preloaded by the ring 132.
