Title: Improvements in or relating to the production of silicon monocrystals
IPC: C01B33/02
Filed: 1962-11-28
Abstract: <PICT:0970765/C1/1> Silicon is deposited as a monocrystalline layer on a surface of monocrystalline silicon heated to a temperature of at least 800 DEG  C. from vapour formed by an intermittent electric discharge between silicon electrodes at a pressure of not more than 10-5 mm. of Hg. A spark or arc discharge may be employed. The spark gap may be 5 mm.  The electrodes may have a diameter of at least 1-2 cm. and may be rotated.  They may be moved alternately towards and away from the deposition surface.  They may be preheated.  The vessel walls and electrode mountings may be cooled. The deposition surface may have been etched with chlorine. Deposition may be effected on a plurality of small silicon crystals attached to an electrically heated base of molydenum, silicon or siliconized graphite, resistance, induction or capacitive heating being employed.  The deposition surface may be 7 cm. from the electrodes. A doped layer may be produced from doped electrodes.  As shown in Fig. 4, silicon from electrodes 1 and 2 passes through an opening in a wall A of molybdenum and is deposited on silicon crystals K on an electrically heated base U in an evacuated vessel B of quartz.  As shown in Fig. 3, each silicon electrode is attached to a carbon mounting a embedded in a water-cooled copper sleeve b.

Patent GB-988440-A (GB)
Title: Method and apparatus for detecting a mark on a translucent sheet
IPC: G01N21/55
Filed: 1963-11-18
Abstract: <PICT:0988440/C1/1> Score lines along which sheet glass is to be subsequently cut are detected by passing through the material a thin-beam of light and detecting variations in the amount of light passed when the beam encounters a line.  Light from a lamp 4 illuminates a slit 19 to form a thin beam of light parallel to the lines on a glass sheet moving across the window 21.  The light passing is reflected by a mirror 41 to pass back through the glass sheet to a photo-electric cell 30.  Slits 50 and 40 are located in front of the mirror 41 and the photo-electric cell 30 respectively. Each score line gives rise to photo-electric cell pulses when it crosses the axes X-X1 and Y-Y1, and the first only of these may be selected by using it to trigger a monostable blanking circuit having a time constant greater than the interval between the pulses.  The light source and photo-electric cell may be displaced through 90 degrees to a plane at right angles to the direction of sheet feed, in which case only one pulse is produced.

A lock-chamber 1 through which fuel element magazines are transferred between a storage chamber 2 situated above a chamber containing the reactor core (not shown) and an elevator leading to the atmosphere outside the reactor as disclosed in the parent Specification, is formed within the thickness of the concrete pressure vessel wall 3, the door 4 of the lock-chamber being movable within the chamber 2 to give communication between the chamber 2 and chamber 1. The door 4 is elliptical and pivotal through 90 degrees about a vertical shaft 7 between the open and closed positions. When the door is in its closed position a flap 5 is moved rectilinearly relatively to the remainder of the door by a jack 15 so that seals 18 on the door periphery abut an elliptic seating 17 at the end of the lock-chamber 1. In a modification (Figs. 4, 5, not shown), the door, instead of being pivotal, is moved along a rectilinear path between its open and closed positions.

Title: Improvements in or relating to the regulation of reheat steam temperatures in boilers
IPC: F22G5/20
Filed: 1965-10-29
Abstract: 1,049,280. Regulating steam temperatures. SULZER BROS Ltd. Oct. 29, 1965 [Oct. 29, 1964], No. 45931/65. Heading F4A. The temperature of reheated steam entering a low pressure turbine 19 is controlled by varying the heat exchange between the reheat steam and live steam on its way to a high pressure turbine 12, in a coaxial tube heat exchanger 11 situated in the flue of the boiler. Water from pump 1 is fed through the economizer 3 and evaporator 5 of once-through force flow, force flow or natural circulation boiler 2. The high pressure steam produced is separated from any water in trap 7, and then passed through superheater surface 9 to tube 10, from whence the flow splits into two parts, part flowing through inner tube 20 of coaxial tube heat exchanger 11 to give up heat to reheat steam passing in co-current flow through outer tube 21, and then flowing to tube 14, via superheater surface 13, while the remainder flows directly to tube 14 .through by-pass line 22. From tube 14 the recombined high pressure flow passes through superheater surface 15 to high pressure turbine; 12. The partly expanded steam from high pressure turbine 12 flows for reheating through outer tube 21 of the heat exchanger 11 and through reheat superheater surface 17 on its way to low pressure turbine 19. The temperature of the reheat steam at the inlet to turbine 19 is maintained constant by varying the high pressure steam flow through the by-pass 22 by valve means 23, and by injecting cooling water into the pipe 10, under the action of controller 25 actuated by temperature detector 24. The high pressure steam temperature at the inlet to turbine 12 is maintained constant by injecting water into pipe 14 under the action of controller 31, actuated by temperature detector 30. In modifications the by-passed superheater surface 13 may be situated before the coaxial tube heat exchanger 11, and the water injection into tube 10 may occur after the branching off of by-pass line 22 (Fig. 2, not shown).

The steel may consist of 3% Ni, 3% Mo, 0.2% C, remainder Fe.

A power-driven hand-applied tool, such as a fret-saw, has the rotary movement of a driving shaft 20 converted into reciprocatory movement of a push rod 23 attached to the tool by an eccentrically-driven pin 32 engaging a groove 26 in a block 25 attached to the rod, a second groove 27 at 90 degrees to the groove 26 being provided in the block to enable the tool to be driven with its cutting plane adjusted through 90 degrees. The grooves extend between surfaces 28 . . . 31 on two faces of the block so that rotation of the block through 90 degrees permits either groove to be engaged by the pin 32. The surfaces 28, 29 or 30, 31, according to the position of the block, bear against the face of a member 21, which is screwed on to the shaft 20 of a drill and carries the pin 32, to prevent rotation of the push rod during its reciprocation. Annular grooves on the surface of the member reduce friction between the member and block.
