Title: Improvements in containers for cosmetics and the like such as rouge
IPC: A45D40/06
Filed: 1931-02-17
Abstract: 357,921. Cosmetic &c. holders. GANGNEREAU, R., 71, Boulevard Beaumarchais, Paris. Feb. 17, 1931, No. 4999. [Class 18.] In a container for cosmetics &c., e.g. rouge, a cup 6, Fig.. 2, for holding the cosmetic is projected or retracted by means of a pin 8 on the cup engaging a straight slot 12 in a rotatable tube 1 and a spiral slot 10 in a fixed tube 9. The tubes are mounted in an oval protective shell 24. The tube 1 is rotated for retraction by rotating a knob 5 which also tensions a spring.23 which operates the return movement. The mouth of the tube 1 is closed by a cover made of two segments 18<1>, 18<2>, Figs. 6 and 8, in order to economize space, of which 18<1> is rigid with and 18<2> loose on a rotatable rod 14, Fig. 4, carrying a partially toothed wheel 62 engaging with a toothed wheel 17 rotated with the knob 5, the arrangement being such that the rod 14 is rotated during part only of the movement of the knob, and so that a pin 31 on the segment 18<1> moves along a slot 30 in segment 18<2> until this segment is rotated also. The cover may be formed in three or more parts. The parts are locked in position with spring 23 tensioned by a rod 35, Fig. 4, operated by a button 37 and having a nib which engages a notch in wheel 62. When this rod is pushed down against the pressure of a compression spring, the spring 23 comes into operation, the cover is opened and the cosmetic projected. The cosmetic is withdrawn and the cover closed by rotating knob 5 by hand. The amplitude of the movement of the cosmetic tube 6 is made variable by making the amplitude of the rotation of tube 1 variable. For this purpose a projection 38, Fig. 5, on knob 5 is stopped either by the pointed end of a plate 39, or, when the plate is rotated, by some other part of its periphery. The plate engages frictionally within and serves as a lid for a tube 40 which may contain toothpicks, smoker sweets, &c. The tube 40 may be omitted and the plate 39 pivoted in any other suitable way. In a modified form shown in Fig. 14, adapted to be operated with one hand, the tube 40 and spiral spring 23 are omitted and the device operated by a thumb-wheel 26, a segmental cover being employed as before.

IPC: F42B22/10
Filed: 1917-04-10
Abstract: 127,306. Joessel, A. J. V. R. Jan. 11, 1917, [Convention date]. Laying mines; mines, marine; torpedoes, locomotive.-Consists in making a torpedo with a front part detachable from the rear part after a given time, the front part acting as a mine, and the rear part carrying the propelling-gear and serving subsequently as an anchor for the front part. In the form shown, the front part A of the torpedo comprises a buoyancy chamber H and an explosive charge J, and is secured against a water-tight joint a on the rear part of the torpedo by a hook U pivoted at Y to a bracket Z on a rod W, which is pressed rearwards by a spring W<3>. When the pressure in the usual compressed-air reservoir C has fallen to a. given value after a given run, a pressure gauge T opens a spring-controlled valve g admitting air to a spring-controlled piston i, which then draws a cam j from the end o of the hook L and opens a valve m by means of a link l; the mine A is thus unhooked and at the same time expelled by the air supplied by the valve m to the chamber B behind the mine. The spring of the valve g can be regulated from outside by a button f to adjust the moment of release. The release of the mine may be determined by clock-work instead of by the reduction of pressure in the reservoir C, and when this release takes place, the rear part of the torpedo sinks to act as an anchor, a mooring-cable M<1> being paid out from a drum M, the spindle of which screws into a nut P. The paying-out is stopped when the drum touches the nut, and the effective length of the mooring-cable is therefore determined by the adjustment given to the nut through bevelgearing R, S from outside the torpedo.

Title: Improvements in or relating to the purification of alkyl phenols and to their conversion into phosphoric esters
IPC: C07F9/12
Filed: 1945-03-02
Abstract: Alkyl phenols obtained from petroleum and free from water are purified by heating them with aluminium chloride under subatmospheric pressure to distil off water and other volatile products, and thereafter they may be converted into phosphoric acid esters of improved stability by treating them with a phosphorus-halogen compound such as phosphorus oxychloride. Advantageously, the weight of anhydrous aluminium chloride used is from 1 to 3 per cent of the weight of the alkyl phenols. Preferred alkyl phenol starting fraction have boiling ranges from 200 DEG  to 250 DEG  C.  In examples: (1) an alkyl phenol fraction derived from petroleum and having a boiling range of from 200 DEG  to 225 DEG  C. is heated in a still to remove water.  After the addition of anhydrous aluminium chloride it is gradually heated to 140 DEG  C. under a pressure of 250 mm. mercury gradually increased to 380 mm. in a period of 2 to 3 hrs.  After the distillation of volatile products, the pressure is reduced to 50 mm. and the alkyl phenols are distilled at a temperature not exceeding 160 DEG  C.  The product p  may be heated with phosphorus oxychloride.  (2) A petroleum alkyl phenol fraction having a boiling range of from 220 DEG  to 245 DEG  C. is heated in a still to remove water and, after the addition of anhydrous aluminium chloride, is gradually heated to 150 DEG  C. under a pressure of 300 mm. gradually increased to 400 mm. in a period of 3 to 4 hrs.  After the distillation of volatile products, the pressure is reduced to 50 mm. and the alkyl phenols are distilled as in (1) to obtain a product which may be converted into the ester as in (1).

Abstract: 699,890. Magnetron amplifiers. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 5, 1952 [March 15, 1951], No. 5805/52. Class 39(i) [Also in Group-XL(b)] A travelling wave tube, preferably with crossed electric and magnetic fields, comprises a delay line of linear or incomplete cylinder form which is made up of two interdigitated comb members each having two ends; the structure is made asymmetrical by different dimensions and/or positions of the combs, and the line has a width of less than 4/#, so that the fundamental wave, i.e. the wave of largest amplitude, which is also the most rapid wave, is a modified dissymmetrical wave of positive phase velocity the field of which is not zero in the middle plane of the line. In one form, Fig. 3a, the comb-like members are displaced with respect to one another parallel to the beam direction to give varying spacing and in another form, Figs. 4a, 4b (not shown) the relative displacement is perpendicular to the plane of the paper. In Figs. 5a, 5b (not shown) the interdigitated fingers have different lengths and in Fig. 6 the fingers of different lengths are carried by members c, d at right angles to one another, the. structure forming a single block. In further forms the fingers are of different cross section such as rectangular strips of different widths or thicknesses, Figs. 7, 8 (not shown) circular rods with intermediate rods of triangular, L or T section, Figs. 9-12 (not shown). One set of fingers may be of tapering form or may be provided with enlargements or slots at their free ends, Figs. 14, 15, 16 (not shown). Various combinations of asymmetries can be used to eliminate undesired modes more efficiently as described with reference to Figs. 9-13 and 17 (not shown). Some of the circular rods of Figs. 9-12 (not shown) may be of loss material having magnetic properties, such as a suitable alloy, for example to introduce attenuation over a small fraction of the length of the line. A metal member carrying the finger supports may form part of the tube envelope, to facilitate heat dissipation. The design features of the line are discussed mathematically. Specification 663,728 is referred to.
