Title: Sport shoe
IPC: A43C15/16
Filed: 1962-11-20
Abstract: 987,073. Studs for athletic footwear. A. DASSLER. Nov. 20, 1962 [Oct. 24, 1962], No. 43906/62. Heading A3B. The sole of a sports shoe has thickened portions forming downwardly extending bulges 5, a supporting element 1 with a lateral anchoring projection 3 is embedded in each bulge and the sole portion above, and a detachable spike or stud 9 is received in each element, each spike having laterally extending flange 12 to increase the braking surface of the spike and the undersurface of each bulge extending laterally beyond the flange of the corresponding spike. The supporting elements are positioned during the operation of vulcanising or spraying the sole so that the material of the sole penetrates through perforations 8 and prevents rotation of the elements. Each element extends from the top surface of the sole to the bottom surface of the bulge, and is internally threaded to receive the threaded spigot 10 of the spike. Flange 12 has a flat upper surface to engage element 1 and an embedded lower surface, and has recesses 13 to receive a tool for tightening or loosening the spike.

Title: Constructional materials derived from developable chevroned structures and a method of making such materials
IPC: E04C2/30
Filed: 1963-11-07
Abstract: Constructional materials are made from developable chevroned structures by subjecting a sheet of material to be folded to an initial preforming operation by embossing its surface which embossing initiates the formation of the chevroned troughs of the structure to be made.  Preferably, the bases of the troughs are rounded.  The term "chevroned structure" is defined as in Specification 991,035.  The sheets may be paper, metal or synthetic plastic.  If the chevroned structures have broken ridge lines then the preforming operation is performed so as to create small troughs all along the broken ridge lines of these structures and also along the fold lines which connect the ridge lines, Figs. 4-6 (not shown).  During the preforming operation, each face of the sheet to be chevroned may be initially provided with a series of embossed troughs which occupy the exact location of the future flanks of the structure to be formed so as to reinforce the flanks.  Preferably, the troughs are embossed alternately in opposite directions so that each convex ridge of one flank lodges inside the concave trough of the flank facing it, Figs. 7-9 (not shown).  The sheet to be folded may be corrugated or pleated. Figs. 10-12, 17 and 18 (all not shown), or may be a laminate comprising a corrugated or pleated sheet covered on one or both faces with a sheet having a smooth surface, Figs. 13-16, 19 and 20 (not shown).  When the chevroned structure has been fully contracted it may be subjected to a post-forming operation by an embossing tooling which acts on the bottom of the troughs of the structure along the lines bounding the flanks of the troughs, Figs. 21 and 22 (not shown).

Abstract: 1495470 Cathode-ray tube circuits LOEWE OPTA GmbH 27 Oct 1975 [21 Dec 1974] 44126/75 Heading H4T In a TV receiver, to prevent screen burn from a bright spot on switch-off, and to act as a line flyback blanking circuit, a capacitor 3 connected to the grid of the tube is fed via a resistor 2 from positive supply UB2, but is brought down to near ground potential, applying a negative potential to the grid, when the switching circuit conducts on loss of forward line scanning pulse at 8 on switch off or during flyback. The switching circuit comprises transistor I driven by transistor 6, the base of 6 being positive during forward pulses, causing it to conduct to hold transistor 1 non conducting. The pulses must exceed the drop on base current across diode 9, Zener 10, resistor 11 and base-emitter junction of transistor 6. The grid of the tube is held near ground by rectifier 5 until caused to swing negative, the swing being near the level of the normal positive voltage on capacitor 3. Alternative embodiments eliminate the Zener by taking the two emitters to a positive reference voltage (Fig. 2, not shown), and eliminate the driver transistor 6 by accepting reversed scanning pulses (Fig. 3, not shown).

Abstract: The autoclave (10) has a pressurised working chamber within which an endless conveyor passes the objects to be treated through a hot water bath. A wall (14) divides the working chamber into a treatment zone (15) and a heat exchange zone (16). Arranged in the latter zone above the water level (11) there are an inlet port (12) and an outlet port (13) which interact with locks (23 and 59, respectively). The objects to be treated are accommodated in perforated conveying containers (18). The conveying containers (18) are supplied and removed by an external conveyor (17). Heat transfer takes place, in the heat exchange zone (16), between the conveying containers passed back through the working chamber from the circulation and those which have just been introduced. As a result, the heat losses are reduced. <IMAGE>
