Title: Process and apparatus for the production of ammonia
Inventor: FUDERER ANDRIJA
IPC: C01C1/04
Filed: 1982-08-06
Abstract: In a pressure swing adsorption system for the purification of hydrogen to be used in an ammonia synthesis gas, nitrogen is employed as a purge gas at an elevated purge pressure. The hydrogen recovered at adsorption pressure contains about 20-25% nitrogen and is advantageous for use as said ammonia synthesis gas. The purge gas is expanded to generate power that can be used to compress air being passed to an air separation system. The nitrogen recovered therein can be employed as said purge gas, while the oxygen recovered can conveniently be employed in a hydrogen generation system used to form said hydrogen passed to the pressure swing adsorption system.

Patent GB-2147172-A (GB)
Title: Imaging or like apparatus
Inventor: THORNTON JOHN
IPC: H04N5/225
Filed: 1984-09-20
Abstract: Where detectors, for example in thermal imaging apparatus, have been necessarily periodically irradiated at a predetermined level to provide a grey level reference this has hitherto been effected by periodically moving an opaque member in the form of a blade onto the optical path to intercept the radiation normally incident upon the detector. Since it is a mechanical arrangement, the blade is difficult to operate in the precise time intervals; thus the present invention comprises the replacement of the blade and its drive mechanism with a liquid crystal assembly 1, 2, 3. The liquid crystal assembly becomes diffusive when a voltage is applied giving a relatively uniform level of radiation at the detector 5 which may be used to provide a grey level reference. <IMAGE>

Patent GB-857942-A (GB)
Abstract: 857,942. Sewage treatment. FYLDE WATER BOARD. March 13, 1959 [March 13, 1958], No. 8086/58. Class 111. A sewage tank is provided with a first series of vertical rods mounted on a set of rotary arms which project radially from a central spindle rotatably mounted in the tank, a second series of vertical rods being rigidly mounted within said tank and spaced apart radially so as to enable the moving rods to pass between the said fixed rods, whereby said first series of rods constantly move through the mass of the sludge to cut a large number of vertical channels therethrough which permits the water to escape and separate to the upper part of the mass from which it can be drawn off, said sludge being prevented from rotating as a whole by said second series of rods. If desired the sludge may be thickened (dewatered) in a first tank and further thickened in another series of tanks. For the production of thick sludge a batch process as specified later is desirable. Moreover, there must not be any upward flow of thinner sludge being admitted to the tank(s) to counter the settlement of the thickened sludge. The second treatment of the sludge may be effected in any one of three tanks A, B, and C as shown in Fig. 3 the tanks being used in rotation for filling, thickening and emptying and the tanks are preferably cylindrical with tapered lower ends and arranged side by side. If desired the rails may be hydraulically or electrically operated with time sequence operation for the necessary interlocks. The capacity may be doubled by adding one further tank and making the cycle of operations one tank filling, two tanks thickening, and one tank emptying. The lower ends of the fixed and moving rods are provided with chains of sufficient length to hang down and touch the corresponding coaxial rod whereby the moving rods and chains cut a continuous passage through the sludge thereby cutting the latter over substantially its entire depth into annular laminae.
Patent GB-2188392-A (GB)
Title: Rotary drive
Inventor: FRITZ DALE
IPC: F16H19/00
Filed: 1986-03-25
Abstract: A mechanism for converting reciprocating motion to rotary motion comprises a flexible cord (54) held between a reciprocating drive element (52) and a stretchable tensioning member (64), the cord being wrapped about a driven spindle (22) which it frictionally engages when the cord is in tension on both sides of the spindle, but which it slips around when the cord is loose on one side of the spindle. The reciprocating drive element thus alternately rotates the spindle by pulling on the tensioned cord, and slackens the cord allowing it to be drawn back over the spindle by the tensioning member. A flywheel (24) on the spindle maintains continuous high speed undirectional rotation. The reciprocating drive element can be a bow carrying the tensioned cord between its ends. Two cords (54, 56) in a single bow wound oppositely around the spindle permit power strokes in both directions of the bow. Alternatively a treadle drive may be used. The mechanism may power a bobbin winder (10), a spinning machine, a string making machine or a threshing machine. <IMAGE>
