Title: Improvements in or relating to stiffeners for boots and shoes
IPC: A43B23/08
Filed: 1927-10-24
Abstract: 279,513. Pittroff, A. Oct. 25, 1926, [Convention date]. Stiffeners; stiffeners, machines for. -Layers of fabric, leather, cardboard, or felt stiffened with glue are fastened together prior to insertion in a shoe by a seam e or otherwise in such a manner that they retain their relative position and on immersion in a softening liquid, penetration can be effected uniformly between the layers. The softened stiffener n, Fig. 3, is held between fingers f of a holder shaped to a counter and the forward end m of a pressure lever k. The stiffener can be inserted in position in the shoe by this tool without the operative having to touch it with his fingers.

Title: Improvements in or relating to indicating instruments
IPC: B64D43/00
Filed: 1956-09-17
Abstract: 821,557. Final indicators for measuring systems. DEUTA-WERKE (VORM. DEUTSCHE TACHOMETER-WERKE) G.m.b.H. Sept. 17, 1956 [Nov. 23, 1955], No. 28297/56. Class 40 (1). [Also in Groups XXXIII and XL (c)] A cathode-ray tube indicator comprises a cathode-ray tube with a substantially flat rectangular screen and a planar electron beam producing a line image on the screen which is deflected transversely to itself or orientated in accordance with the magnitude of a quantity to be measured. Fig. 1 illustrates an aircraft instrument panel comprising a plurality of such indicators, scalar quantities such as engine speed and altitude being displayed as vertical displacements of the line images on the vertical screens 2 .. 6 and angular quantities such as heading and artificial horizon being displayed by orientation of the line images on the horizontal screens 7, 8, 9. The controls for each vertical indicator are arranged so that the central position of the image corresponds to the desired value of the input quantity, these datum positions being in horizontal alignment. The images may be blanked out when in their datum positions to prevent screen burn and the image focus may be varied in accordance with the deviation of the image from its datum position. The calibration scales may be adjacent the screens as shown or they may be in the form of self-luminous lines on the screen. Each indicator tube 33, Fig. 4, may be mounted in a rectangular metal screening case 34 which can be plugged into the instrument panel, the front edge 39 of the case 34 having an inwardlysloping flange against which the flat screen of the tube abuts; the scale 41 may be applied to the side flanges; cut-outs or projections 40 in the top and bottom flanges facilitate removal of the case. If the image is displaced to either end of the screen, the electron beam impinges on an electrode 38 to actuate an indicating or safety relay device.

Title: Forming sheathed jointed cables
IPC: H02G1/14
Filed: 1977-07-08
Abstract: In this method a cable, which comprises a conductor (1), an inner semiconducting layer (3), an insulating layer (4) and an outer semiconducting layer (5), is bevelled by means of a corresponding bevelling device in such a way that a piece of the conductor (1) is exposed, in order to be welded to a second cable end treated in the same way. Furthermore, during bevelling, the insulating layer (4) is tapered, the said layer being cut off just before it tapers away to the underlying semiconducting layer (3). In this, only the cut surface of the layer (3) is exposed. Following this, an expanding device in the form of a tapering sleeve (6) is pushed between the layer (3) and the conductor (1), whereupon these two are lifted apart and the layer (3) is opened out. Remaining in this position, the intermediate space between conductor and layer (3) is filled with a semiconducting polymeric material. After that, the damaged outer layers are restored by applying the corresponding materials and the necessary after-treatment operations, such as hardening, grinding etc. This avoids cutting partially into the semiconducting layer and its after-treatment. <IMAGE>

Abstract: 340,036. Cooling brakes. BOUGHTON, E. B., 3, Berners Street, London. Sept. 24, 1929, No. 28939. [Class 103 (i).] A method of dissipating or absorbing the heat generated by friction between braking surfaces consists in utilizing such heat to convert water or other fluid into steam or vapour under pressure. In the form shown in Fig. 2, the brake drum 1 is provided with an external fluid jacket 5 into which extend cooling fans 2 on the periphery of the drum, and in addition, or alternatively as in Fig. 4, the brake shoes 10 are of hollow formation comprising fluid chambers 10a, and are mounted on pivots 11 through which fluid is introduced into the chambers. The outlet for the vapour from each chamber 5, 10a is controlled by a spring-loaded non-return valve 8, 14 which can be set to open at a predetermined pressure while the valve 8 may serve as a filler cap to close an orifice through which fluid is introduced into the chambers 10a. Preferably the chambers are connected to a fluid reservoir by way of non-return valves so that on a partial vacuum occurring in any chamber, liquid is drawn in. As shown in Fig. 4, the vapour generated escapes through the valves 14 and is led through pipes 15, 19 by means of channels 20, 21 to ejector nozzles 17 and discharged so as to induce a flow of air across a series of cooling vanes 18, the flow of vapour over the rim of the drum being confined by an external sleeve 24.

Oct. 20, 1931, No. 29061. [Class 37.] The direction of energy flow in an alternating- current conductor is found by feeding the current to a measuring instrument in series with a resistance and noting the deflection, a current proportional t o the voltage being then supplied between two predetermined points on the resistance, the increase or decrease of the deflection indicating the direction of flow assuming the connections unchanged. The instrument transformer connections of Specifications 327,837, [Class 37, Electricity, Measuring &c.], or 376,478, [Group XXXV], may be employed. As shown, the transformer embraces a conductor link 6 in a junction box, its secondary winding 13 being connected to the measuring instrument 3 and series resistance 11 provided with scale range tappings 15, 17. The potential circuit is connected across the points 21, 23 on the resistance 11, contact being made to the neutral 7 and to the transformer core which contacts with the link 6. A condenser 29, or inductance, together with a resistance, may be employed in the potential circuit to bring the two currents into, or 180‹ out of, phase with each other. The transformer may have an arrow indicating, for example, the direction of flow when the current deflection is increased by that due to the voltage.
