Title: Film handling system and takeup and supply mechanism therefor
IPC: G03B21/43
Filed: 1968-12-31
Abstract: 1,207,040. Film handling system. STROMBERG DATAGRAPHICS Inc. Dec.31, 1968 [Jan. 2, 1968], No. 61881/68. Heading G2E. [Also in Divisions G4-G6] A film or tape handling system for use with resilient film or tape having a widened portion near one end comprises supply and take-up mechanisms having spools with flanges spaced wider than the film but narrower than the widened portion of the film. As shown in a microfilm reader, the supply mechanism includes a cartridge 37 having a supply spool 27 and a tangential exit slot 41 adjacent a capstan 16 and pinch roller 17. Flanges 23 of supply reel 27 are spaced wider than the film 11 but narrower than a widened portion of the film 12, located a distance from the film end 13, so that the widened portion 12 may be gripped frictionally between the flanges 23. Before unwinding, the portion of film 11 beyond the widened portion 12 extends tangentially to the reel, the end 13 resting against curved surface 39 of the cartridge and on rotation of reel 27 the end 13 emerges from exit slot 41 and is gripped by the capstan 16 and pinch roller 17. The tangential velocity at the periphery of capstan 16 is greater than the speed imparted to the film by rotation of the supply reel 27 and the speed of the capstan 16 once the film is gripped determines the speed of the film by means of a slip clutch in a known manner. A lump or projection 50 is located between flanges 23 to force the film end between the flanges when the film is rewound.  The take-up mechanism 18 comprises a film guide 47 defining an octagonal inner guide surface 48, and a take-up reel 19 having flanges 23 the upper one of which is circular and positioned above as seen in Fig. 3 and overlapping the guide 47 while the lower one is octagonal and slightly smaller than the inner edge of guide 47 to enable removal of the reel, Fig.7 (not shown). When reel 19 is rotated with respect to the film guide 47 the guide is overlapped by the point of the octagonal flange. The film 11 is urged into passage 24 by the capstan 16 and guided by surface 48 between the flanges 23 near the peripheries. When the widened portion 12 passes between flanges 23 it is gripped frictionally and, as the reel is rotated at a speed such that its tangential velocity is greater than the speed imparted to the film by capstan 16, the film end is forced towards the hub 52 Figs. 4, 5 and 6 (not shown) and finally looped around it. The film then tightens and by means of a slip clutch the reel rotates at a slower speed to match the speed of the incoming film. Provision may be made to allow the widened portion of film to lie flat against the hub of the take-up reel by spring mounting the upper flange 23 Fig. 7 (not shown) so that it may be displaced axially relative to the hub.

Title: Glucuronidase activity and/or phdependent pharmaceuticals and their methods of production and use for selective treatment of diseases
IPC: G01N23/00
Filed: 1979-10-02
Abstract: Hyperacidified tumors having high ss-glucuronidase activity can be treated with glucuronides with aglycones toxic to the tumor cells with great safety toward the rest of the body by first administering an alkalinizing agent in an amount sufficient to maintain the pH level of non-tumor tissues at approximately 7.4 during the glucuronide treatment. This will cause inactivation of ss-glucuronidase activity in the rest of the body. When nitrile-containing aglycones are used sodium thiosulfate is also administered to avoid cyanide poisoning. Novel glucuronides are disclosed the aglycones of which exert a higher toxic effect in an acid environment or are water-soluble only in an alkaline environment. Such compounds have particular utility with the above process. By substituting radioisotopes into the aglycone, diagnosis and in situ radiation therapy may be accomplished. Bacterial cells having ss-glucuronidase activity may also be diagnosed and treated in accordance with the present invention. A urine test is disclosed to determine the amount of free glucuronic acid in the urine which is an indication of the presence of a tumor in the body having high ss-glucuronidase activity. Novel methods of synthesizing the glucuronide used in the present invention are also disclosed.

Title: Echo location apparatus
IPC: G01S13/538
Filed: 1980-06-10
Abstract: An echo location apparatus includes an image store (13) (preferably digital) and a display tube (38). During each echo location period the received signals are stored in positions determined by their location coordinates and with their correct intensities. The build-up of stored signals is such that moving located objects are represented in the display by a plurality of traces, positions occupied by such objects during previous echo location periods being possibly shown with diminished brightness. The read-out of the store is at a fast flicker-free TV scan rate. True motion shifts may be given to the scan signals, and the 'now' position of the own object may be maintained in the centre of the display. <IMAGE>
Patent GB-2053048-A (GB)
Title: Regulated pouring of molten metal into a mould
IPC: B22D39/02
Filed: 1980-06-27
Abstract: The ladle (19) is rotated from a horizontal rest position to an inclined pouring position under the control of a speed regulator. The movement of the ladle occurs in three different steps, each involving a different rotation speed. In a first step tilting of the ladle at a first speed allows the molten metal to move close to a delivery spout of the ladle, in a second step tilting at a second, lower, speed causes the slow pouring of most of the molten metal, and in a third step tilting entailing a progressive acceleration to a third rotation speed, higher than the first, causes the pouring of the residual amount of the molten metal. The ladle is thus rotated substantially in the same way as it would have to be rotated manually for a correct pouring of the molten metal. <IMAGE>

Title: Method and apparatus for purifying a gas mixture
IPC: F25J5/00
Filed: 1980-08-13
Abstract: In order to remove a relatively high boiling point impurity from a gas mixture containing the impurity, the gas mixture is heat exchanged with cryogenic medium (typically liquid nitrogen) so as to freeze-out the impurity. Some of the gas mixture (typically exothermic gas) is precooled in a preliminary heat exchanger 34, and the remainder is precooled in the one of a pair of freeze-out heat exchangers 30 and 32 undergoing regeneration. The two parts of the gas mixture are combined and passed through the other (active) one of the freeze-out heat exchangers 30 and 32 so as to freeze-out impurity by heat exchange with liquid nitrogen. Nitrogen vapour, thus formed, is used to provide cooling for the preliminary heat exchanger. After a while, the efficiency of the active heat exchanger in freezing out the impurity becomes impaired. Valves are provided so as with the fluid stream such that the previously regenerating heat exchanger becomes the active one, and vice versa. Compressed air may be used to regenerate the passage in which impurity has been frozen out. <IMAGE>

Title: Self-sealing socket
IPC: H01R13/52
Filed: 1980-10-07
Abstract: A socket (12), which is self- sealing, includes a bore (20) housing a spring (26) and a plunger (28), which are connected together. A flexible gasket (30) on the outer lip opening of the socket (12) includes a hole which receives a portion of the spring loaded plunger (28), thus sealing the socket against moisture penetration. When a pin (54, figure 2 not shown) is inserted into the socket (12), it forces the plunger (28) back into the bore (14), compressing the spring, and the pin (54) then acts with the gasket (30) to provide a seal, while it also makes electrical contact with the bore (14) of the socket. The plunger (28) may be made from insulating material to provide a safe front end and prevent potential shock hazard from the unmated connector. <IMAGE>
