Title: Coin-feed vending machines for picture postcards
IPC: G07F11/04
Filed: 1968-11-11
Abstract: A coin-freed postcard vending machine is operated manually by a spring-loaded lever 6 driving levers 15 and 16 through an intermediate coin to rotate shaft 11 carrying a ratchet 20 co-acting with teeth 21 on a friction drum 12 separating postcards from a stack in compartment 24.

Title: Improvements in or relating to a rotary duplicator for printing a predeterminable number of lines from stencils
IPC: B41L11/00
Filed: 1969-02-18
Abstract: In a rotary duplicator for printing one, two or three selected lines on copy sheets by predetermined tripping of the impression cylinder the latter is actuated by three cams rotating with the printing cylinder and having a single follower, which selectively may be common to all three cams and which, acts through lever linkages to move the impression cylinder. At each of the positions of the cams which provide single, double or treble lines on each copy sheet, electrical switch means associated with electromagnets and levers and follower rollers are provided such that through actuation thereof a succession of copy sheets may issue from the duplicator each bearing the same number of lines i.e. one, two or three, but such lines being different on each copy sheet. To effect single line duplicating, each copy sheet bearing a different line image, it is sufficient to switch on the machine and press a push button but for two and three line duplicating bearing lines a control rod is twisted into a first position-for two lines-and a second position-for three lines.

Title: Preheating in yarn texturing
IPC: D02G1/02
Filed: 1969-05-29
Abstract: For producing crimping therein, multi-filament yarn is pulled, with the filaments substantially flat and parallel, through first contact heater means, the filaments are assembled into a twisted yarn, and the latter is pulled through second contact heater means. Untwisted multi-filament thermoplastic yarns 12, 13 pass from respective spools 10, 11 through pre-twister means 14, such as described in Specification 1007813, and are then led by pulleys 15 and a guide 16 to tensioning means 17, the yarns then passing via a pulley 19 downwards in flat, parallel formation to engagement with the surface of an arcuate groove 31 formed longitudinally in an elongated, vertically-disposed hollow body 30 heated by steam via a pipe 33. From groove 31 the yarns pass through opposed crotches of crossed rollers 81, 82 freely journalled in a fixed support 83, whereby the yarns become progressively assembled into a twisted yarn 18 which passes upwardly into engagement with the surface of a longitudinal groove 32 formed in body 30. The twisted yarn is guided by rollers 42, 43, 43 to a descending direction, the twist being set by cooling, either natural or artificial, at this stage. The crimped component yarns 12, 13 are then separated over fixed pins 61, 62 by traction from pairs of conical rollers 65, 66 and are wound on takeup rollers 73, 74. A tensioner 120 may be inserted between groove 31 and the rollers 81, 82 to increase the tension in the twisted yarn. In a modification only one multi-filament yarn is treated, the pre-twister means 14 and the separating pins 61, 62 then being omitted, and twisting means 121 being located immediately in advance of the relevant traction rollers.

Patent ES-437477-A1 (ES)
Title: Grinding method and apparatus
IPC: B24B49/00
Filed: 1975-05-06
Abstract: A method of feed grinding workpieces comprises moving a workpiece into pressure contact with a grinding wheel and rotationally driving the grinding wheel relative to the workpiece at a predetermined speed of rotation different than the resonant frequency of the grinding wheel spindle assembly to effect feed grinding of the workpiece. Completion of the feed grinding or spark-out is detected after which the rotational speed of the grinding wheel is lowered to another predetermined speed different than the resonant frequency of the grinding wheel spindle assembly when operating in the spark-out mode. The high speed rotation during feed grinding assures good grinding quality and the low speed rotation during spark-out assures good surface finishing. By rotating the grinding wheel spindle assembly at speeds other than its resonant frequencies, damage due to large vibrations of the assembly is avoided.

Title: Method and apparatus for the microbiological production of single-cell protein
IPC: C12N1/16
Filed: 1978-10-11
Abstract: Method and apparatus is described for the microbiological production of single-cell protein making use of ethanol as a base material thereby allowing the protein produced to be used for human consumption. The process involves the cultivation of ethanol activated yeasts at temperatures between 20 DEG and 40 DEG C. under aerobic conditions in a fermentation column containing a dilute nutrient medium having a pH value in the range 2.5 to 5 containing nutrient salts, acid phosphate and nitrogen-containing substances in which the nutrient medium is continuously circulated into and through and out of the fermentation column and at each re-entry into the column is introduced tangentially into a zone which is oxygen enriched using oxygen gas molecules in the range 1 to 7 mu to form a bio-mass which can be separated and dried to form a protein product. The formation of a large gas bubble in the fermentation column is prevented by carrying the process out under a positive pressure and a gas extraction stage is provided immediately beyond the column. Pure oxygen or oxygen-enriched air may be used. In apparatus for performing the above method the pump for circulating the medium from the heat exchanger to the column is located in a conduit between the heat exchanger and the column. Dispersion of the oxygen or oxygen-enriched air is achieved by one or more sintered plates.

Title: Biocidal gas sterilization method and apparatus.
IPC: A61L2/20
Filed: 1979-12-28
Abstract: In a method and apparatus for timely determination of potentially harmful biocidal gas leakage from a pressurized chamber during sterilizing operations, biocidal gas make-up values are monitored during the sterilizing phase to provide prompt warning of biocidal gas leakage. The timing of preselected pressure decrement gas make-up charges (along 92) are measured and compared to minimum acceptable gas make-up charge times. In addition, absorption of biocidal gas by the load can be compensated for, if timing along the first pressure decrement (along 84), in sterilizing operations where load absorption is a significant factor. Also, gas absorption by the load can be predicted from steam absorption data obtained during pressure-controlled conditioning cycles, by monitoring steam introduction (along 34).
