IPC: A43B13/14
Filed: 1943-03-16
Abstract: 578,879. Boots &c. GHEZ, H., and GHEZ, O. March 16, 1943, No. 4292. Convention date, Feb. 21, 1942. [Class 17 (ii)] A sole member 1 of relatively stiff, hard or inflexible material is rendered flexible by a series of slots 2 with parallel or converging side walls extending completely through the thickness substantially transversely of the sole from or near opposite edges across a major part of the width. The slots may be straight, curved, as shown, or as a continuous double hair-pin bend, or zig-zag, and, as shown, extend alternately from the opposite edges. Cavities may be formed in the sole or in its upper face. In the latter case, these may be filled with a lightweight filling material such as sponge rubber or cork. Lugs may be formed integrally with the sole for the passage of straps for securing the sole to the foot.

Title: Improvements in roof and similar supports for use in mines and other places
IPC: E21D15/26
Filed: 1953-02-18
Abstract: 746,762. Mine roof supports. HILL PORTER (NEWCASTLE), Ltd., and TALBOTT, A. C. May 17, 1954 [Feb. 18, 1953], No. 4551/53. Class 20(2). A support e.g. for the roofs of mines comprises two screwed relatively rotatable parts the pitch of the screw being such that the endwise thrust on the support causes a tendency for relative rotation to take place which is resisted solely or principally by friction so that only a small twisting moment is required to commence, produce or prevent relative rotation. In the.form shown the support comprises a platform a, a screwed rod b engaging the platform through a spherical seating c and a nut d mounted on a tubular member e which stands on a platform f. The steepness of pitch of the screw of shaft band nut c may be such that the endwise thrust just overcomes the friction and the shaft b turns automatically. In this case a brake or stop is provided on platform a engaging arms g on the rod b to prevent such rotation until required. Alternatively the pitch may be such that the friction normally prevents rotation of rod b. In this case the rod is rotated e.g. by a pipe engaged over arms g. Instead of a single rod, a pair of oppositely threaded rods may be engaged in nuts at opposite ends of a sleeve. In this case the sleeve is rotated to adjust the length of the support and the pitch of the threads used may only be half that in the form shown in order for the same conditions to apply. Where a friction brake is used it may be adjusted so as to yield when the load reaches a predetermined value so that relative rotation takes place and the support yields.

These impedances may include temperature variable elements to compensate for temperature changes. A low-pass filter 39 may also be included to produce a sine-wave output. For highfrequency working, the capacitances of the diodes are neutralized by a further feedback path including a capacitor 42 and a winding 41, Fig. 11.

Fig. 1 illustrates an embodiment of the invention comprising a body assembly having two sections 10 and 11 mounted on a common shaft 12 and movable in relation to each other about the axis of the shaft 12.  The internal passages through body member 10 are connected as illustrated in Fig. 1 with a hollow tube 20 which functions as a sample chamber which by welding or other appropriate means can be arranged to be an operative part of the body assembly. The member 11 is provided with a number of arcuate openings 25 (see Fig. 2) and may extend through an angle sufficiently large to include adjacent internal passages.  The rotational disposition of member 11 determines which of the adjacent internal passages of member 10 of the body assembly are connected through the openings 25.  If the passages are connected as shown in Fig. 3 and are then switched to the connections as in Fig. 2 it can be seen that the amount of fluid from the first stream which was passing through the sample chamber 20 at the instant of such rotation of the assembly is thus introduced into the second fluid stream and becomes the sample.  Fig. 4 and 5 illustrate another embodiment of the invention wherein the two sections 40 and 41 of the body assembly are also positioned in contact with each other.  Figs. 6 and 7 illustrate yet another embodiment in which the stationary member 51 of the body assembly is composed of two sections 52 and 53 which are made structurally unitary by a plurality of interconnecting pins 54 and a number of sample chambers 60, 61, 62, 63, 64 and 65 are contained in the rotatable member 55.

Abstract: 566,201. Coupling aircraft. HLADIL, F. March 27, 1943, No. 4984. [Class 44] [Also in Groups XIV and XXXIII] Means for coupling an auxiliary aircraft to the underside of a main aircraft comprise a cable which can be lowered from the main aircraft for attachment to a spigot member on the auxiliary aircraft, the spigot being then drawn into a socket on the main aircraft to permit the interengagement of seating surfaces provided on the two aircraft. When the aircraft are coupled, connections are established for the transference of passengers, goods and fuel, and for telephone or like communication. An auxiliary aeroplane 2 has pivoted thereto at 7, near its centre of gravity, a spigot 6 adapted to he raised from a housing 8 to a vertical operative position. The spigot has a ball-end 9 adapted to be engaged by spring- urged jaws 12, 13 in a casing 17 attached to a cable 3 and urged by a spring 20 against conical surfaces 15 on the casing so-that the engagement is increased by the pull of the cable. The cable is connected to lifting and lowering gear on the main aeroplane 1 and to effect the coupling operation it is lowered with the casing 17 through a tubular socket 4 on the main aeroplane. It is then caught by V-shaped collecting wires on the auxiliary aeroplane and the end 9 of the spigot 6 having been engaged with the jaws 12, 13, the cable is raised, drawing the spigot into the socket 4 in which it is then locked by catches 23 operated by members 27 pivoted at 26 to the socket. As the spigot is drawn into the socket seating surfaces 30, 31 on the two aircraft are engaged, hatches 32, 33 for the transference of passengers and goods are brought into register, pipes 34, 35 for fuel, oil, &c. are connected and a plug and socket 37, 38 for electrical connections are engaged. An additional spigot and socket 4, 6 may be provided at 49 near the rear of the aircraft. Struts 39 hinged at 40 to each wing of the main aircraft are adapted to be turned downwards laterally by linkage 41, 42 with their lower ends engage stops 48 on the wings of the auxiliary aircraft. In order that the ends of the struts may travel readily on the surface of the wings, they carry wheels 43 with pivots 47, the periphery of each wheel comprising a series of rollers 46, the pivots 45 of which lie in the central plane of the wheel. To permit the separation of the two aircraft, the catches 23 are disengaged and the casing 17 of the coupling device is then moved downwardly by the pilot to disengage the jaws 12, 13 from the part 9, by engaging the jaws with projections 28 on the members 27. The main aircraft may carry an auxiliary aircraft under each wing and a third under the fuselage. The auxiliary aircraft may be a transport or a fighter aircraft, or a glider.
