Title: Heel tightener for ski bindings
IPC: A63C9/083
Filed: 1966-03-09
Abstract: 1,136,170. Heel tighteners for ski bindings. H. MARKER. 9 March, 1966 [10 March, 1965; 2 July, 1965], No. 10343/66. Heading A6D. A heel tightener for ski bindings comprises (a) a tensile element or elements extending along opposite sides of the heel and attached directly or indirectly to the ski, (b) a forwardly open frame extending behind the heel, (c) a thrust member mounted in the frame and (d) at least one spring between the forward end of the thrust member and the means for securing the tensile elements to the ski. The thrust member is mounted for pivotal movement about an axis which is transverse to the ski and parallel with the surface of the ski, the forward end of the thrust member being engageable in the heel groove and adapted to be locked in its clamping position. As shown, cable sections 2, 3 are secured to a turntable 1 of known construction, each cable section carrying a nipple 4, 5 bearing on a compression spring surrounding the nipple at the end of the cable. Each spring 8, 9 engages with a hook portion of a frame 10, and when a fall of the skier causes a strong rearward and upward pressure to be applied to the frame 10, the springs 8, 9 are compressed by the spring washers 6, 7. A locking bolt 11 is secured to the nipple 4, and when the spring 8 has been compressed sufficiently to pull the locking bolt out of an opening formed in keeper 12 for guiding the locking bolt, the pull of the cable effects a pivotal movement of the spring 8 and, as a result, the spring 8 is disengaged from the retaining hook so that the cable 2 becomes detached from the frame 10. Means for restoring the spring 8 to its locking position are described. The frame 10, close to the cross-bar 17, is provided with a shaft 18 on which is pivotally mounted a thrust member 19 which fits the opening in the frame 10 and can be moved upwardly out of the frame. The forward end of the thrust member 19 has a roller 21 which conforms to the curvature of the heel groove. Four modifications of the engaging and disengaging means are also described, and in one of these a gas spring, known per se, is used as a spring element.

Title: Improvements in the manufacture and production of light bricks
IPC: C04B38/10
Filed: 1928-04-05
Abstract: 315,205. Johnson, J., Y., (I. G. Farbenindustrie Akt.-Ges.). April 5,1928. Porous bricks.-In the manufacture of porous bricks by stirring or beating a binding clay and water with a foaming agent, moulding and baking, there is incorporated with the foam a cement or one of the difficulty soluble salts of the alkaline earth metals such as gypsum, to give stability to the foam to facilitate moulding, and optionally also a weakly acid or alkaline substance such as soda, bisulphates, and milk of lime which increases the strength of the bricks on baking. Fillers such as Kieselguhr, fire clay and sand may be employed. As foaming agents, soaps or saponins may be employed but it is preferred to use sulphonic acids, especially those of alkylated aromatic polynuclear compounds, or their salts, sulphuric esters such as Turkey red oil, or the products obtained by sulphonating tars or tar oils or fractions or extraction products of such tar or oils. In the examples isopropyl naphthalene sulphonate and butylated naphthalene sulphonic acid are used.

Title: Improvements in or relating to circuit arrangements for rapidly switching-on inductive loads
IPC: H01F7/18
Filed: 1965-03-11
Abstract: 1,077,924. Switching inductive loads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 11, 1965 [March 14, 1964], No. 10360/65. Heading H3T. An inductor L is energized through an SCR from a high-voltage supply Sp via an RC circuit and a small auxiliary inductor LH. When the capacitor voltage has risen sufficiently, a gating circuit J 8  (details in Fig. 2, not shown) allows a firing pulse Z to reach the gate of the SCR, and the capacitor C rings with the inductor L to execute one quarter-cycle of oscillation, the second quarter-cycle being damped out by the diode D. The capacitor can still ring with the auxiliary inductor LH, however, at a higher frequency, to provide a reverse voltage on the SCR to cut it off. The gating circuit is switched off by the fall in capacitor voltage to prevent firing of the SCR at the wrong time. For short periods of operation sufficient energy is stored in the inductor L to maintain the SCR conducting. For longer periods a holding current is supplied from H via diode Ge and a manually operated switch Sch. A resistor can be connected in series with the diode D to speed the switching off.

Abstract: 501,102. Discharge lamps; illuminant enclosures. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 9, 1938, No. 10941. Convention date, April 12, 1937. Drawings to Specification. [Class 39 (i)] [Also in Group XI] The rays from a gas- or vapour-filled discharge tube excite two successively arranged luminescent layers, of which one at least is a glass layer, the layer nearer to the discharge responding to radiation of shorter wave-length than that to which the more distant layer responds. Greater efficiency is obtained than in a mixture of the materials, as absorption of short-wave radiation by the layer excited by the longer wave-length is avoided. The envelope of a low-pressure mercury-vapour lamp may be of uranium glass coated internally with green-fluorescent zinc silicate. The lamp may be surrounded by a fluorescent glass envelope with the other layer on it or on the lamp envelope. Both layers may be luminescent glass ; copper and uranium glasses may form the internal and external layers respectively of a duplex glass envelope. Specification 473,587 is referred to. The Specification as open to inspection under Sect. 91 includes cases in which neither layer is of glass. In one form the envelope of a lowpressure mercury - vapour lamp is coated internally with blue-fluoreseent zinc sulphide responsive to 3600A radiation, on which is superimposed a layer of red-fluorescent zinccadmium silicate responsive to 2537 A radiation, phosphoric acid being used as a binder. Alternatively the layers may be applied to the exterior of the envelope or on either side of it. This subject-matter does not appear in the Specification as accepted.
