Abstract: 1,183,088. Stacking form-folded webs. MOHAWK DATA SCIENCES CORP. 24 Oct., 1967 [17 Nov., 1966], No. 48334/67. Heading B8R. A fan-folded web of stationery is stacked using a web-engaging and driving means which carries out a cyclic rocking motion governed by the speed of advance of the web and the length of web between folds. Fig. 2 is a diagrammatic view of apparatus in which a web 2, with fold lines therein, is fed first through a buffer chamber 4 then over an air bearing 16 to webadvancing means 6 which also rocks to reform the folds before stacking in hopper 10. Buffer chamber 4.-The bottom surface 20 of the chamber is perforated, and suction is applied by means of a fan 18, the output end of which feeds the air bearing 16; thus, a loop of the web is drawn into the chamber. An optical device 28 transmits light via two slanted mirrors 30 to further mirrors 32 which reflect back into photodetectors connected to the feed mechanism 6 through a control device 26. The feed is activated at a high speed when both light paths are blocked by the loop of the web, at a lower speed when only the upper path is blocked and is halted when neither are blocked. Web-engaging and driving.-The web is engaged and driven by sprockets 22 on an endless chain (34), (Fig. 3, not shown) which pivots between extreme positions 24. The endless chain (34) is driven by a motor at the desired speeds, and the rocking cycle is timed by manually selected gearing, the selection being dependent on the distance between fold lines in the web.

Abstract: 1521120 Reducing contaminant levels in algae STAUFFER CHEMICAL CO 27 Nov 1975 [6 Jan 1975] 48771/75 Heading A1X To reduce the level of trace heavy metal contaminants (arsenic, copper, zinc, mercury, cadmium and lead) in algae containing carrageenan (more than 50% being of lambda non- gel forming type), the algae are treated with an aqueous solution containing an amount of a soluble potassium salt sufficient to reduce the level of the contaminants without extracting the carrageenan from the algae. The algae are Gigartina acicularis or pistillata, or Iridaea; the potassium salt is potassium chloride, tripotassium orthophosphate, monohydrogen dipotassium orthophosphate, or tetrapotassium pyrophosphate. The potassium ion concentration is between 0.1 and 4 moles/litre, and the temperature of the solution should be between freezing point and 7‹C when the concentration is below 1.0 mole/litre and between freezing point and 25‹C when it is above 1.0 mole/litre. The pH of the solution should be between 6 and 10. The time of soaking should be between 10 min and 2 hours in single or multiple soak steps. The weight ratio of solution to algae should be greater than 7:1. Examples are described, in which the level of arsenic in the seaweed or in the carrageenan are measured. Extraction of carrageenan is detected by reacting the solution with isopropyl alcohol.

Filed: 1963-12-20
Abstract: 1,033,747. Amplifier protection. PYE Ltd. Dec. 10, 1964 [Dec. 20, 1963], No. 50295/63. Heading H3T. An amplifier supplying a load through a transformer is protected by sensing when the primary current exceeds a certain value. In the Figure a Class B push-pull amplifier with common-collector transistors VT1 feeds the primary of T1 through resistors R1, a highresistance circuit R2, R3 being joined in parallel. Normally, a is more negative than b and transistors VT2 are cut off. If the load RL is shortcircuited, or if the transformer core becomes saturated due to the passage of a very low frequency signal, a becomes more positive and VT2 conducts, generating a control signal at A. Resistors R2 or R3 may be variable to adjust the protection level. Diodes Dl prevent VT2 from conducting in the half-cycle when the corresponding VT1 is cut off. R1 also acts as a thermal stabilizer for VT1. The control signal at A may bias back VT1 or cut off the drive signal (by biasing back the driving transistors) or remove the power supply; this protection can be applied by a mono-stable flip-flop which restores normal operation after a few seconds, and then cuts off again if the fault persists. The invention may also be applied to NPN transistors, to valve amplifiers, to single-ended amplifiers and to Class A operation.
