Title: Mobile crop driers
IPC: F26B11/12
Filed: 1970-11-12
Abstract: 1324246 Mobile crop driers C VAN DER LELY NV 12 Nov 1970 [18 Nov 1969] 53982/70 Heading F4G The variation in weight, volume or moisture content of a crop being dried is used to control the hot air supply of the drier. The drier comprises a moving-floor chain conveyer 13, through which hot air is passed from a burner 31, and a chain conveyer 20 carrying tines 30 which are caused to pivot by means (not shown) near the front sprockets 27 to discharge crop. The doors 10 and the flap 9 can be opened to allow the admission of the rear-end of a pick-up wagon for loading the drier, and after drying the flap is pivoted backwards so that the crop falls from the conveyer 20 on to a transverse conveyer 35 feeding a delivery blower 36. Flaps 84 may be raised or detached to uncover gauzecovered apertures in the side walls 2A. In the fist embodiment, Fig. 2, conveyer 13 is secured to an arm 45 pivoted to a weighing arm 43 acted on by a-spring 41 and secured to a rod 46. The rod 46 operates by means of an element 47 a switch 49 when the weight of the crop has been sufficiently reduced (60-80% of moisture removed). The switch 49 and a humidity meter 51 are both connected to controller 33 which controls electrically operated burner valves (not shown). In Fig. 3 (not shown), the weight of the drying chamber 1 is supported during drying by pressure detectors in the form of carbon resistors. The carbon resistors, an electric thermometer and a humidity meter are connected to the controller, which employs transistor circuitry. In Fig. 4 (not shown), the volume of the crop is detected by disposing a perforated aluminium plate on the crop on the conveyer 13 so that portions of the plate project through openings in the side walls 2A of the drying chamber so as to operate on adjustable switch connected to the controller 33 as the crop increases in volume on drying. In Fig. 5 (not shown), the volume of the crop is detected by disposing a grating on the crop on the conveyer 13 so that the grating interrupts the light beam from a light source to a photo-electric cell(s). The cell is connected via a delay relay with the controller 33. In Fig. 6 (not shown), the side walls 2A of the drying chamber 1 are electrically insulating and support metal plates connected to one pole of a current source, and a central metal plate is connected to the other pole. When the current has fallen sufficiently because the crop is dry enough, the burner control valves are operated. In Fig. 7 (not shown), the variation in weight of the crop is measured as variation in the tyre pressures of the drier.

Title: A process for doping semiconductor bodies
IPC: C30B31/06
Filed: 1965-12-22
Abstract: 1,086,660. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. Dec. 22, 1965 [Dec. 22, 1964], No. 54477/65. Heading H1K. In a process for doping a semi-conductor body a supply of a compound of the doping substance in the vapour state is brought into contact with the body at an elevated temperature so that the doping substance is deposited on the body and begins to diffuse thereinto, the supply is then cut off and the body maintained at the elevated temperature to allow the deposited doping substance to diffuse further into the body, and the supply is thereafter resumed to enable deposition to recommence. In the embodiment illustrated in Fig. 1, silicon discs 8 to be doped are supported at one end of a sealed quartz ampoule 3 and a mass 5 of gallium is placed on a silicon support 6 at the other end. At the beginning of the process the discs are heated to about 1250‹ C., and silicon from the discs combines with the quartz of the ampoule to form gaseous silicon monoxide which flows towards the gallium 5 at a temperature of about 1100‹ C. The silicon monoxide reacts with the gallium to form gaseous gallium oxides which in turn flow to the vicinity of the discs 8 and decompose in contact with the discs to deposit metallic gallium thereon. The flow of gases is controlled by a quartz plug 10, containing a magnetic body 11 of cobalt, which can be moved into and out of sealing engagement with a frusto-conical sleeve 9 by means of an electromagnet 14a, 14b. In a modification (Fig. 2, not shown) the plug is moved by inertia relative to the ampoule by means of hammers (15, 16) which are adapted to strike opposite ends of the ampoule to move it sharply in one or other direction. In a further modification the plug is moved under gravity by tilting the ampoule. In an alternative embodiment the deposition of gallium on the silicon discs is arrested by interrupting the flow of silicon monoxide to the gallium mass, and this is achieved by providing a condensation zone (30<SP>11</SP> or 30<SP>111</SP>) either at the end of the ampoule remote from the mass (Fig. 5, not shown) or between the mass and the discs (Fig. 6, not shown). When the temperature of this zone is raised the silicon monoxide evaporates and deposition is resumed.

Title: Improvements in or relating to automatic liquid level control systems
Inventor: ALON YOSEF
IPC: G05D9/12
Filed: 1968-11-19
Abstract: 1,214,070. Automatic liquid level control. YISSUM RESEARCH DEVELOPMENT CO. Nov.19, 1968, No.54804/68. Heading G3R. A valve is opened to supply liquid to a container by the triggering of a semi-conductor controlled rectifier when the liquid in the container falls below a predetermined level, and is closed by the rendering non-conductive of a power transistor in series with the rectifier when the liquid rises above a higher predetermined level. As described, fall in the level of liquid, e.g. liquid nitrogen, in a container below a probe 2 comprising four seriesconnected silicon diodes covered with a length of shrinkable tubing causes a change in resistance, due to rise in temperature, which, through a transistor 4, triggers a semi-conductor controlled rectifier 6 so that a solenoid 5 is energized to open a valve (not shown) allowing more liquid to flow into the container. When the level rises above a probe 1 higher than, but similar to, probe 2, a transistor 3 is influenced to render a power transistor 7 non-conductive thereby de-energizing solenoid 5 and closing the valve until the level falls below probe 2 again. Positive feedback through a resistor 27 ensures positive operation when solenoid 5 is de-energized and a push button 26 can be operated if it is desired to supply liquid to the container when the level is between the two probes. Circuit protection and stability is provided by diodes 11, 17, 21 and a condenser 25.
