Patent ES-360568-A1 (ES)
Title: Thread takeup lever arrangement for a sewing machine
IPC: D05B51/00
Filed: 1968-11-22
Abstract: A thread take-up arrangement comprises an oscillatory lever having one end adapted to draw the thread upwards after the formation of a stitch, and an elongated cover covering said one end over its entire movement and having a substantially U-shaped cross-section with two slits being oppositely located in lateral walls, characterised in that the slits join in the upper end of the cover to permit the thread to be placed in the slits and to freely contact an upper surface of said lever end. As shown, the crank 10, carrying a crank pin actuating the pitman 5 driving the needle bar 7, has a second crank pin 11 to which is pivoted a sleeve 37 slidably receiving a rod 38 rigid with the thread take-up lever 12. One end of the latter is pivoted at 39 to the machine frame, and the other end is hook-shaped to receive the thread, and oscillates within a cover 30 formed at its opposed sides with thread-passing slits 31 which merge into an upper slit (32) partly closed by a tongue 36. The lever end is perforated to receive either a plastics pin or a felt plug, the ends of which engage the opposed surfaces of cover 30 to guide the lever therein and to prevent passage of the thread 18 beneath said end. The latter may, alternatively, be provided with a thread-guiding eyelet. In a modification, the inner end of lever 12 is pivoted on pin 11, and lever 12 is pivoted intermediately to a swinging link.

Title: Improvements in and relating to semiconductor devices
IPC: H01L29/87
Filed: 1969-06-26
Abstract: To cut down edge leakage current, the central zone of a symmetrical multilayer switching element is made thicker at the outside of the element than in the centre. The diode shown is one of many cut from a single wafer produced by the following process. An N-type silicon wafer 6, 7 doped at 7.1017 atoms cm.-3 is coated with borosilicate glass which is then selectively removed except at the areas corresponding to the thick central parts of regions 5, 8. The wafer is then heated in the presence of powdered silicon doped with boron and of powdered silicon doped with arsenic. Boron from the glass diffuses into the wafer with a surface concentration of 5.1020 atoms cm.-3 boron from the doped powder diffuses (mainly) into the exposed surface of the wafer with a surface concentration of about 7.1018 atoms cm.-3 and arsenic from the other doped powder diffuses into the exposed surface of the wafer (only) with a surface concentration of 2.1019 atoms cm.-3. The slow moving arsenic forms the N-type regions 11, 12. Nickel electrodes are applied across each major face by electroless deposition to short out the PN junction at those faces. The electrodes thus formed are provided with a gold coating, leads are connected, and the diode is provided with an envelope.

Title: Method and apparatus for controlling heat flow from a drawn sheet of glass
IPC: C03B15/04
Filed: 1969-12-20
Abstract: In the production of sheet glass 17 by drawing upwardly from a bath 16 of molten glass through a forming zone 22 and deflecting the sheet about a bending member 25 into a substantially horizontal plane while separated from the member 25 by a fluid film through a slot 29, the sheet 17 is maintained at a substantially uniform temperature for deflection over member 25 by transferring heat from the newly drawn sheet to coolers 21 with a heat-absorbing surface 33, heat being conducted away from the surface 33 at a rate sufficient to maintain the surface at a temperature below that of the glass sheet and within the range 300 to 1000 F. In addition to the coolers 21, which are divided into compartments 39 through which cooling water is flowed, the sheet 17 may be protected by one or more insulating panels 34, 47, which may be positioned along a rod, as 35, as required and may be partially or completely rolled up on to rod 35. A pan of triangular shape, as shown in Fig. 2, or a single panel with triangular ends (Fig. 3, not shown) may be used, so as to blend their heat conserving effect inwardly from the edges of the sheet. They are preferably of quartz cloth or like flexible material but stainless steel or light-weight ceramic may be used. The coolers 21 preferably have the surface 33 formed by a layer of asbestos cloth painted with a black, high-temperature, paint. A conventional cooler 46 may be positioned below the roll member 25 to absorb heat therefrom. Heaters may be provided in chamber 22 if required and may be directed against the panels 34, 47 which are then of heat-reflecting material or the panels may incorporate electrical resistance heaters.
