Patent ZA-812429-B (ZA)
Title: Improvements in or relating to lead lights
Inventor: FREDERICK QUADLING DARRELL
IPC: B44F1/06
Filed: 1981-04-13
Abstract: A method of forming a simulated lead light involves the application of opaque cames to the surface of a transparent or translucent sheet of material, in which the opaque cames are built up successive applications of adhesive and opaque particulate material, such as silicon carbide. The adhesive can be screen printed onto the carrier surface and the particulate material can be dusted onto the printed adhesive. The application of adhesive and particulate material can be repeated until a raised came of desired thickness is built up on the carrier surface to simulate a lead came. The method can also be used in conjunction with the screen printing of colors onto the carrier surface to simulate stained glass separated by simulated lead cames.

Title: A method of ventilating cylinder pockets in a cylinder dryer and apparatus for carrying out the method
Inventor: ANDERSSON KARL HUGO
IPC: F26B13/08
Filed: 1981-10-13
Abstract: A cylinder dryer usually includes a plurality of heated cylinders (4) about which a web-like material (1) is taken in a zig-zag mode and pressed against certain of the heated cylinder surfaces by means of an endless high-permeability wire (3), whereby cylinder pockets are formed between the cylinders (4), web (1) and wire (3), when the latter relinquishes contact with the web at a cylinder surface (6) to pass over a return roll (7) arranged between the cylinders, and once again makes contact with the web at the next following cylinder circumference (8). According to the invention these cylinder pockets are ventilated by a flow of drying air from a blowing box (9) being blown over the width of the wire against its surface facing away from the cylinder, in a direction forming an acute angle to and having a directing component substantially counter to the direction of travel of the wire. Blowing is carried out thereby within an area (6) where the wire relinquishes contact with the web. The blowing box (9) is also provided with means (11) arranged for preventing an interface layer of moist air about the circumference of the return roll being introduced into the cylinder pocket upon rotation of the return roll.
Patent ZA-818443-B (ZA)
Title: Switching arrangements in coin testers
Inventor: DUBEY PIERRE
IPC: G01N27/00
Filed: 1981-12-04
Abstract: The coins (37) come within the coil field of an oscillator (2,6,7). Within a reverse feedback path of the oscillator amplifier (2), several resistances (11 to 18) are arranged, switchable parallel to each other individually or in any desired combination, by switching transistors (21 to 28), each controlled by a program (29). This makes the amplification controllable step by step. The program (29) has a constant-value-storage (49) with a stored standard value for the amplification in which oscillations cease whenever the field coil area is free and a calibrating resistance (35) is connected parallel to the condenser (7) of the oscillator (2,6,7). For each coin type, two pre-determined standard limit values of amplification are stored in the constant-value-storage (49), with the oscillations ceasing between them in the presence of an acceptable coin (37). Prior to each testing operation, the program (29), with calibrating resistance (35) being connected parallel to the condenser (7) increases the amplification step by step until oscillations cease. The quotient of the thus obtained amplification value and the standard value is multiplied by the two standard limit values of each type of coin, and the product is stored in the read-write-memory (59) as the nominal limit value. During the coin testing, the amplification is altered step by step from the highest nominal limit value to the next lower, and so on. A coin acceptance signal is issued whenever the oscillator oscillations do not cease with the higher of the two nominal limit values and do stop with the lower of the two nominal limit values.

Title: A method for separating gaseous,elementary mercury from a gas
Inventor: WIKLUND JOHAN ELOF
IPC: B01D53/64
Filed: 1982-04-19
Abstract: The invention relates to a method for separating gaseous elementary mercury from a gas in conjunction with a wet-gas cleaning process comprising a plurality of washing stages. The mercury-containing gas is treated with an aqueous washing liquid conducted in a closed circuit, the liquid containing 0.1-300 mmol/1 mercury (II) ions and at least twice this amount of ions having the ability of forming complexes with mercury (II) ions, the mercury in the gas being oxidized and absorbed in the washing liquid. The invention is characterized in that the treatment process is carried out in conjunction with a gas-cooling process effected after the last washing stage of the wet-gas cleaning process, to form a condensate for absorbing the halogens contained in the gas. The resultant condensate is transferred to the washing liquid and the mercury (II) content of the washing liquid is maintained by contacting the washing liquid with an oxidizing agent for mercury (I) ions. The agent used to oxidize mercury (I) ions is preferably chlorine gas.

Inventor: ISHIDA TAKASHI
IPC: H03L7/18
Filed: 1978-12-12
Abstract: An electronic timepiece has an oscillator for generating a high frequency time standard signal which is frequency-divided by a multi-stage divider circuit. A memory stores time adjustment information for use in adjusting the time in the event the oscillator time standard signal is higher than a predetermined frequency. The memory is connected to a preset circuit for presetting the divider circuit in accordance with the content of the memory. The divider circuit comprises 16 dividing stages and when no time adjustment is needed, the divider output is taken from the 15th stage in the conventional manner whereas when time adjustment is being carried out, the divider output is taken from the 16th stage. A selecting circuit applies either the output form the 15th or 16th stage to a display device depending on whether or not time adjustment information is stored in the memory.

Abstract: A fuel cell having an anode, a cathode and an ion exchange membrane is supplied by hydrogen fuel through an anode fuel delivery conduit. A recirculation loop is provided to recycle gases in the fuel delivery conduit to a mixing point where a controlled flow rate of fuel is supplied and mixed therewith. Any oxidant species remaining in the fuel delivery conduit are thereby combusted in a controlled manner to avoid damage to the fuel cell membrane-electrode assembly. Small quantities of oxidant may be deliberately introduced into the fuel delivery conduit to generate water vapor and heat to pre-condition the fuel delivered to the anode. Such preconditioning assists in hydration control of the membrane, and temperature control of the membrane-electrode assembly for optimum fuel cell performance.
