Patent GB-840380-A (GB)
Title: Tension adjusting means especially for textile machinery
IPC: D02H13/00
Filed: 1956-09-03
Abstract: 840,380. Beaming machines. SUCKER G. m. b. H. GEB. Sept. 3, 1956 [Dec. 31, 1955], No. 26827/56. Class 142(1). [Also in Group XVI] In a beaming machine in which a warp 1 or other web is fed at constant speed by a roller 3, a roller 4, operating in a loop 1a of the warp and displaceable along horizontal guides 4b, reduces the speed of the beam 5 to keep the tension constant. The roller 4 is loaded by fluid pressure acting on a piston 6 coupled by a cable to a drum on a shaft 9a, other drums on the shaft being coupled by cables 9c to the bearings of the roller 4; the load, and hence the tension of the warp, can be adjusted by a relief valve in the circuit of a pump 7. The shaft 9a acts through a chain 10 on a variable-stroke pump 11, normally set at zero delivery, whereby movement of the roller 4 to the right due to increase in the tension of the warp causes the pump to supply a motor 15 controlling a variablespeed gear 30 driving the beam 5. Limit switches 34 stop the machine if displacement of the roller 4 is excessive.

Title: Improvements in and relating to fuel cells
IPC: H01M4/86
Filed: 1965-06-25
Abstract: Sintered fuel cell nickel cathodes are made from a powder layer (1) of a mixture of 60-40% carbonyl nickel and 40-60% nickel carbonate and a powder layer (2) thinner than (1) and formed on top of (1) and consisting of 20-30% carbonyl nickel, 20-30% nickel carbonate and 60-40% of a pore former such as ammonium carbonate and sodium chloride, the powder layers being compacted together and sintered in hydrogen at 650 DEG -750 DEG C.  The carbonyl nickel has a grain size of 2-5 microns and the ammonium carbonate a maximum size of 60 microns.  The sintered cathode is boiled in an ammoniacal solution of silver carbonate and ammonium carbonate and then reduced to form silver at 150 DEG C. in hydrogen.  Alternatively the silver carbonate may be cathodically reduced.

Title: Improved process of manufacturing active carbon
IPC: C01B31/12
Filed: 1933-09-30
Abstract: Active carbon is prepared by carbonizing raw material, such as peat, and bringing it while still hot into contact with a solution of a dehydrating agent such as zinc chloride.  Carbonization is effected at 200 to 300 DEG  C. in an externally heated container, zinc chloride solution being then added and the temperature raised to and maintained at 350 DEG  C.  Extraction with water and hydrochloric acid, is then effected after which the carbon is washed with water, dried and ground.

The spool valve is driven by the drive sleeve through lost motion means. The spool valve element is not moved until the drive sleeve has moved so that the spring means is well past the bottom of the indentation in which it was most recently engaged and when the valve is at the null point the spring means is on a level with the inwardly inclined wall of the approaching indentation.
