Title: Ribbon securing device
IPC: A41F11/02
Filed: 1954-07-08
Abstract: 766,373. Strap fastenings. PUGNIET, J. F. P. July 8, 1954 [July 8, 1953], No. 20026/54. Class 44. A fastening device for securing a ribbon, if desired an adjustable ribbon, to an object such as a corset, another ribbon, or the other end of the same ribbon comprises a base 3 to which is hinged a stiff loop member, the base being a piece cut from a profiled stock of elastically deformable material such as rubber, of a length slightly smaller than that of the loop member. As shown in Fig. 2, a stocking suspender clip 5 of the type described in French Specification 1,002,093 is secured to a corset 7 by the fastener. Two loop members 1, 2 are used and these are connected in holes 30, 31 in the base 3. The stocking clip 5 is connected to the loop member 1 by a ribbon 4 which passes over one limb of the loop member and the width of this loop member is such that the ribbon is compressed between the limb of the loop member and the base 3 which has an extension to position the loop member in the position in which it engages the ribbon 4. The loop member 2 is of greater width than the portion of the base 3 to which it is connected so that it can pivot freely and a ribbon 6 to which the corset 7 is connected passes round the loop member and is sewn to the corset. In another construction, Fig. 7, the loop members 1, 2 are mounted in grooves in the base 3 instead of in holes so that they are detachable. The loop member 1 engages the base 3 in a similar manner to that of the construction described above so that the ribbon 4 is trapped between the base 3 and the loop member 1. The loop member 2 engages over a hook-like projection 33 and in the engaged position of the loop member the relative dimensions of the projection and loop member are such that the ribbon can move freely on the loop member. In a further construction, Fig. 4, two hook-like projections 33, 34 are used on the base 3. The projection 33 is identical with the projection described above but the projection 34 is made so that it firmly engages the loop member 1 so that the ribbon 4 to which the stocking clip 5 is connected is trapped between the loop member and the base 3.

Title: Improvements in lip stick cases and the like
IPC: A45D40/02
Filed: 1932-07-15
Abstract: 390,038. Cases for lipstick &c. ROLOT. G. and LEMASSON, H., Route de Dijon, Beaune, Cote d'Or, France. July 15, 1932, No. 20064. [Class 18.] A case for lipstick and the like of the type in which the opening of the cover 3 and the presentation of the contents occur at the same time by sliding a button 8 in a longitudinal slot 6 has a central fixed tube 10 carried by the base 9 of the case and a jacket tube 16 which slides and turns on the fixed tube, and actuates the cover and closes the longitudinal slot 6 when the case is closed. A pin 7 fixed to the button 8 and lipstick socket 12 passes through longitudinal slots 6, 11 in the outer casing 1 and fixed tube 10 respectively and a slot in the jacket tube 16 composed of two parts, a longitudinal part 17a and a lower part 17b which is either helicoidal or partly inclined with a straight transverse portion at the end. The jacket tube also has two other slots, one in which the pin 15 on the fixed tube engages so as to guide the movement of the jacket tube, and the other in which a pin 5 on the cover engages so that the cover is locked or actuated. The guiding slot has a helicoidal part 18a and a straight transverse part 18b. The actuating slot has a straight longitudinal part 19a, a helicoidal part 19b shaped correspondingly to the slot 18a, and an inclined part 19c. The cover 3 pivots about the pins 2, and the casing has an arc-shaped slot for the passage of the pin. A developed view of the fixed and jacket tubes and cover in the closed position, is shown in Fig. 6. To open the case, the pin 7 is moved in the direction of the arrow f<1>. This lifts the jacket tube 16. At the same time, the latter is caused to rotate by the engagement of the pin 15 with the slot 18a. This lifting and rotation continues until the pin 15 reaches the slot 18b, when lifting ceases but rotation is continued until the pin 7 leaves the slot 17b and moves in the slot 17a. When the case is in the closed position the pin 5 lies in the slot 19b and rotation about the pivot pins 2 cannot occur. Movement of the jacket during opening causes the pin to be brought into engagement with the slot 19c, which causes rotation of the pin 5, and the cover 3, about the pivots 2.

Filed: 1946-07-09
Abstract: 616,840. Pulverulent-fuel furnaces. INTERNATIONAL COMBUSTION, Ltd. July 9, 1946, No. 20475. Convention date, Aug. 21, 1945. [Class 51 (i)] In a pulverulent-fuel furnace comprising a primary combustion chamber A communicating through a restricted outlet B with a secondary combustion chamber C leading to a flue D, the fuel-air mixture is admitted downwardly at high velocity, e.g. 6,000 - 24,000 ft. per minute, through a nozzle 10, and secondary air is admitted at high velocity through an annular inlet 12 containing a ring of pivoted vanes 131 so as to impart a swirling motion to the mixture, which ignites on entry. Further air is admitted at high velocity, e.g. 12,000-60,000 ft. per minute, through four circumferentially spaced inlets 16 to drive unburnt fuel inwardly, these inlets being inclined at an angle to the radius (see Fig. 3, not shown) so as to maintain the swirling motion. Similar inlets 161, 1611 are provided at lower levels so that unburnt fuel is repeatedly driven inwardly. The restriction of the outlet B enables a super-atmospheric pressure, e.g. 2 - 110 inches of water, to be maintained in the chamber A. The furnace temperature is maintained above the fusion point of the ash so that molten slag is flung outwardly on to the chamber wall and adheres thereto. This slag drips off the wall into the base of the chamber C from which it is removed through a door 17. Any solid combustible particles adhering to the slag are burnt at the chamber wall. The walls of the chamber A are lined with water tubes 7 separated by refractory material, the chamber C is lined with water tubes 9, and steamgenerating coils and superheater tubes (not shown) are located in the flue D. The Specification as open to inspection under Sect. 91 also describes a construction, Fig. 4 (cancelled, not shown) in which the fuel-air mixture is admitted tangentially. This subject-matter does not appear in the Specification as accepted.

In an aerial array comprising a plurality of dielectric rods coupled to a rectangular waveguide at intervals along its length by means of apertures spaced along the length of one face of the guide, the spacing of the apertures is less than a wavelength in the wave-guide, but is so related thereto that a given number of rods forming a group occupy an integral number of wavelengths of the guide, while the dielectric rods are all coupled to their respective apertures through delay means which introduce such different delays for the different members of a group that all the rods radiate cophasally. As shown in Fig. 1, a group of three rods occupies two guide wavelengths. The dielectric rods are mounted within cylindrical segments 2, 12, 22 ... which also incorporate the delay means. For the first rod of each group 1, 31 ... the delay is introduced solely by the material of the dielectric rod within the segments 2, 32 ... ; for the other rods, additional portions of dielectric material 8, 9 are inserted in the segments to effect the necessary delays. The portions 8 inserted in the coupling for the second rod of each group is also arranged to behave as a halfwave transformer, while the portions 9 inserted in the coupling for the third rod of each group is arranged as a three half-wave transformer. Matching screws 5, 15 ... are arranged opposite their respective apertures 4, 14 .... Fig. 4 shows an array wherein a group comprises two dielectric rods, the spacing between the rods being equal to one-half the guide wavelength. In order to effect cophasal energization, alternate circular segments 29 and 39 are constructed with different diameters so that the phase velocities of waves in alternate segments differ so as to effect the necessary phase correction. The energy supplied to the array may be uniformly distributed to all the radiating elements; alternatively, the energization may be " tapered."
