Abstract: 403,531. Cases for cosmetic sticks. LAFORGE, P. C. N., 16, Boulevard PÚreire, Paris. Jan. 18, 1933, No. 1722. Convention date, Jan. 18, 1932. [Class 18.] In a case for a stick of cosmetic of the kind wherein the stick b is carried by a slide c which, through the medium of a plate or lever g, controls the movements of a cover f, the latter is pivoted to the lever g and, when opened, it first slides across the end of the case and then swivels until it rests against the side wall thereof. A knob d screwed into the slide c is pushed upwards when it is desired to project the stick for use, and during the first part of its movement, it abuts against a cam surface g<2> in the lever g and swings the latter from left to right about its pivot i and thus causes the cover to be removed. The knob runs in a slot in the case and also in a slot in a plate m also pivoting about the point i, the plate m normally obturating the slot in the case and being swung from left to right to uncover the slot when the knob d engages a cam surface n <1> in the plate. A spiral spring may be mounted on the pivot of the cover to hold the latter against the top edges or the side wall of the case. A spring presses the slide against the front of the case, and the slide is provided with a projection which engages under a ledge in an inner sleeve e and holds the slide in its lowered position. The lever g is held in contact with the knob d by means of a spring, or both the lever and the plate m are provided, as shown, with further cam surfaces engaged by the knob on its return movement to ensure that the cover is closed and the slot in the case is covered. The lever g is positioned between the sleeve e and the wall of the case and a similar lever also pivoted to the cover and to the point i is positioned on the opposite side of the case. The Specification, as open to inspection under Sect. 91, comprises also a modification in which the cover is hinged to the case and a finger on the end of the lever g, Fig. 7 (cancelled), engages in a spiral groove k<1> in the hinge pin, and the cover is swung round its pivot as the lever g moves from left to right in the groove. The lever also serves to obturate the slot in the case. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to sparking plugs
IPC: H01T13/39
Filed: 1945-02-01
Abstract: 588,197. Making compound wire and sparking - plug electrodes. MALLORY METALLURGICAL PRODUCTS, Ltd. Feb. 1, 1945, No. 2527. Convention date, Feb. 1, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVII] Welding; altering molecular structure.-A sparking-plug electrode or the sparking-tip of the electrode is composed of a wire having a core of high thermal conductivity metal and a sheath of material with a high resistance to erosion, the wire being doubled upon itself or folded to form a loop and the ends of the wire being remote from the sparking-area of the electrode. The sparking-tip may be formed from a wire of circular cross-section and be doubled upon itself and swaged so that its doubled section is deformed to form a sparking- tip 15 (Figs. 2 and 3) of circular cross-section, each portion 13, 14 of the wire being substantially of semicircular cross-section. Alternatively, the wire may be formed into a loop (Fig. 4) and the two ends welded to a flange on the end of a central electrode 18 or the end portion of the rod can be bent into a loop and the ends located in a recess 27 in the insulator as shown in Fig. 8. As a further alternative the rod can be flat in cross-section and doubled upon itself to form two portions which lie against one another and the ends can be welded on to a flange on the central electrode. Instead of forming only the tip of the electrode of the doubled wire, the whole electrode may be of this form. The wire may be formed by passing a wire of the core material through an electroplating bath and then hot or cold drawing the sheathed wire formed, the drawing changing its metallurgical structure and increasing its resistance to erosion. Alternatively, a wire of one material can be brazed into a tube of another material followed by drawing to the desired diameter or a tube may be shrunk on to a rim and then heated in a reducing atmosphere to bond the two without fusion or a tube may be filled with a molten metal of a lower melting point than the tube. The following metals are mentioned as suitable for the core : silver, copper, molybdenum. The sheath may be of any of the following : platinum, nickel or a nickel alloy such as nickel-chromium, nickelmanganese, nickel-molybdenum, nickel-ironmolybdenum and nickel-iron-chromium-molybdenum alloys. In addition to the core and coating, the wire may have an intermediate layer of stronger material.

Abstract: 796,554. Thermal switches. THOMPSON & CO. (SUNBURY), Ltd., R. E., and MACANDREW, J. F. Jan. 28, 1957 [Jan. 26, 1956], No. 2614/56. Class 38 (5). A snap-action switch comprises a leaf-spring 1 carrying a contact 3 and a trifurcated leafspring 2 carrying a contact 4, the springs 1 and 2 being anchored to a common support 5 and the central tongue 11 of the spring 2 being held compressed in the direction of its length by engagement of its free end with an abutment 12 carried by a further leaf-spring 13. In the form shown, a button 9 on a bimetallic strip 7 bears on the spring 1 and an insulating pin 18 forming part of an adjusting screw 17 bears on the abutment 12. Upward movement of the bimetallic strip 7 causes corresponding movement of the spring 1 and, through engagement of the contacts 3, 4, of the spring 2 until the compound spring member 2, 11, 13 snaps over-centre and opens the contacts. When the bimetallic strip 7 cools and returns to its original position, the spring 1 follows it and a stop 15 mounted on a bracket 16 attached to the spring pushes the compound spring member 2, 11, 13 over-centre again to reclose the contacts. In an alternative form (not shown), the spring assembly 1, 2, 13 is inverted so that the button 9 on the bimetallic strip bears on the abutment 12 and the insulating pin 18 bears on the spring 1. Upward movement of the bimetallic strip thus directly causes the compound spring member 2, 11, 13 to snap over-centre and the contacts 3, 4 to open. The spring 13 may also be replaced by a bimetallic strip. The stop 15 may be replaced by a contact which co-operates with an additional contact on the spring 2 so that these contacts are closed when the contacts 3, 4 are open and vice versa. The switch is suitable for use in an electric iron.
