Title: Improvements in and relating to airscrew blades
IPC: B64C11/24
Filed: 1941-04-17
Abstract: 549,417. Airscrew blades. CHARLES, H. N., and FAIRHURST, L. G. April 17, 1941. N. 5010. [Class 114] In a hollow metal airscrew blade of the kind in which the front and rear faces 10, 11 are constituted by sheet metal plates welded together at the leading and trailing edges 14, 15 and reinforced by an internal stiffening web 19, each plate is formed with a longitudinal slot 17 or 18 of the same length as the web, so that the web may be engaged in the slots from outside the plates 10, 11 and welded thereto subsequently to the welding together of the plates. Preferably a more secure welding of the web is obtained by forming the slots 17, 18 with chamfered edges as shown in Fig. 3. The web 19 may either be solid or have perforations 20 stamped therefrom for reducing its weight. The thickness of plates and web preferably decreases from the root to the tip of the blade, which may be fitted with a separately formed and welded tip as described in Specification 541,759.

Title: Multiplex signal transmission system
IPC: H04J3/12
Filed: 1977-02-08
Abstract: 1522912 Multiplexing INTERNATIONAL STANDARD ELECTRIC CORP 8 Feb 1977 [13 Feb 1976] 5100/77 Heading H4M In a multiplex signal transmission arrangement main and auxiliary input signals are sampled and multiplexed by the multiplexer directly to form a resultant bit stream so that no additional equipment, such as a buffer register and associated logic circuitry, is required for the insertion of the auxiliary signals into the bit stream. As shown, multiplex signal transmission equipment comprises a plurality of main signal input channels mch1-mch32; a signal output channel T19; a clock CL, DIV1-4, generating a plurality of sampling pulse trains; a multiplexer MC controlled by said clock to sample a main input signal on each of said input channels using one of said pulse trains having a frequency related to the frequency of the input signal, the thus sampled signals being supplied in a multiplex fashion to the output channel together with auxiliary signals ach1-ach32 which are sampled by the multiplexer. This latter sampling operation is performed by pulses which are so distributed among the pulses belonging to a set of at least two sampling pulse trains by which the main input signals of a set of at least two main input signals are sampled at a same frequency that the pulses of said sampling pulse trains of said set are mutually interleaved and mutually equidistant. The way in which this is effected is described in detail with reference to Figs. 3 to 8 (not shown), and a suitable receiver for the multiplexed signal is described with reference to Figs. 9 to 12 (not shown).

Filed: 1918-03-23
Abstract: 136,855. Marks, E. C. R., (Blake, C. C.). March 23, 1918. Connecting uppers to insoles and soles; lasting, methods of.-In the manufacture of welted footwear, the upper is updrawn only and d t h e n permanently secured to the edge face of the insole, after which the welt, upper, and insole are secured together with the lower faces of the welt and insole in the same plane. The edge face of the insole, or the adjacent face of the upper, or both, are treated with cement, and the upper, after updraw, is firmly pressed against the edge of the insole by a binder 3, Fig. 3, which is held in position by a clamp comprising a bar 4 slidably supporting two posts 5, 6, each of which is provided with a horn 8, Figs. 2 and 3, adapted to pass through a hole 9 in the upper and engage beneath the insole, and a curved spring metal jaw 10 and a foot 12 arranged to engage, respectively, the side and top edge of a hump 11 on the binder. The post 5 is slid along the bar, preferably by means of a pair of toggle pincers 13, 14, Fig. 3, until the clamp is tightened, and then further pressure causes the post 5 to tilt and lock on the bar 4. The heel seat of the shoe mav then be lasted, after which the shank of the shoe is lasted in the machine shown in Figs. 4 and 5. The shoe is positioned on a last-pin 18 at the head of a post 19, and cement is applied to the edge of the insole between the clamped upper and the heel seat; the cement is contained in an electricallyheated pot 23. The free ends of the binder 3 are then engaged by clamping-jaws 24 carried by posts 25 slidable on a bar 26, after which spring-pressed arms 29, normally occupying a raised, inoperative position, are engaged beneath the bar. These arms are then moved inwards by crossed bellcrank levers 36 operated from a treadle, causing the jaws 24 to clamp upon the binder 3, and then to yield upwards, so that the binder wipes the upper along the edge of the last and finally presses it against the edge of the insole; the posts 25 then tilt and become locked on the bar 26. The operative parts of the machine are then restored to their original positions, and the shoe carrying the clamps is taken from the machine. After the cement is set, the clamps are removed and the welt is sewed in, as shown in Fig. 11, so that its bottom surface is flush with the bottom face of the insole. Instead of cement, thread or metallic fastenings may be used. Specification 19094/10 is referred to.

In a selenium rectifier of the kind in which a cadmium compound (e.g. selenide, sulphide or telluride) is applied to the selenium layer or to the counter electrode by vaporization a small quantity of thallium (or indium or gallium) is incorporated at the same time, e.g. by vaporizing a cadmium compound which already contains thallium or by vaporizing cadmium compound and thallium from the same or different vessels. The thallium and cadmium selenide, for example, are evaporated on to the selenium either simultaneously or alternately, or during overlapping periods thereby thoroughly incorporating the thallium and allowing control of its amount so that no unattached thallium atoms remain to migrate to the selenium. A cadmium or cadmium coated counter-electrode is used to increase the cadmium content of the intermediate layer near the electrode.
