Patent GB-126609-A (GB)
Title: Improvements in or relating to Power Transmission Mechanism.
IPC: B24B47/04
Filed: 1919-02-27
Abstract: 126,609. Norton Grinding Co., (Assignees of Norton, C. H.). May 4, 1918, [Convention date]. Reversing-gearing.-To avoid shocks in the starting and stopping of reversible worm-andwheel gearing for driving the reciprocating table of a grinding-machine &c., the worm 15 and its shaft 16 are both capable of independent axial movement permitting the load to come gradually to rest under its own momentum. The shaft 16 is driven from a shaft 17 through a reversing- clutch 27. and the worm is driven by conical friction clutches 32, 33, one at each end of the worm 15. Rollers 42 carried by the shaft engage cam surfaces 40 on the clutch parts 32 to move the worm axially at the commencement of its motion in either direction. During this period, the worm does not rotate but acts as a rack driving the worm-wheel 14 at an increasing speed until the surfaces 32, 33 come into contact, when the worm rotates at full speed. At the end of each reciprocation, the shaft 16 is moved axially by inertia to an extent limited by shoulders 51, 52 at .the ends of a ball thrust bearing 47, and the parts are brought slowly to rest by friction, after which the drive in the opposite direction commences. Lost motion may be provided in the reversing- clutch 27, as indicated in Fig. 3, rendering the clutch ineffective while the parts are coming to rest.
Patent GB-1015262-A (GB)
Title: Virus culture
Inventor: MACPHERSON IAN ALEXANDER
IPC: C12N7/08
Filed: 1962-02-09
Abstract: A virus cultivation process compriser maintaining a viable culture of cells derived from the baby golden hamster kidney fibroblast cell line designated BHK 21 in a nutrient culture medium, inoculating the culture with a virus to which the cells are susceptible and cultivating the virus in the culture. Suitable viruses are foot and mouth disease virus, Newcastle disease virus, fowl plague virus, arthropod-borne encephalitis viruses, herpes simplex trachoma and influenza virus.  BHK 21 is developed from a known baby hamster kidney culture by trypainising the monolayers of cells before they are completely confluent, subculturing every 4th or 5th day with 1/10 to 1/20 of the cell suspension using a medium consisting of 10% unheated calf serum and 10% autoclaved tryptose phosphate broth in Eagle's basal medium modified to contain twice the normal concentration of amino acids and vitamins.  After several transfers (30 days), all cells except cell line BHK 21 ceased to grow.  These cells were trypsinised, resuspended in a medium containing 20% calf serum and 5% glycerol and cooled to -70 DEG C. After 6 days, the cells were thawed at 37 DEG C. and cultured for a further 35 days to produce fast-growing, stable cells.  For the production of vaccines, the viruses, cultured as above, are processed by methods known per, se.

Abstract: 822,651. Oxygen tents. OXYGENAIRE (LONDON) Ltd. Feb. 20, 1958 [Feb. 20, 1957], No. 5786/57. Class 81 (2). An oxygen tent comprises a canopy 10 to be supported over a bed and in which air is circulated and a cooling device comprising a box 19 which is closed at the bottom, receives air from the tent through an opening at its top and contains or is surrounded by cooling means, a tube 27 extending from the box 19 to the canopy 10 and receiving air from the box 19 through a Venturi 28 into which a jet of oxygen is directed. The box 19 is mounted within a pedestal 14 which also houses a refrigerating unit, the cooling coils 31 of which are disposed in the box 19. The tube 27 passes through openings in the box 19 and pedestal 14, respectively, and is of smaller cross-sectional area than either of the openings. The canopy 10 is supported on a frame 34 and has an opening 26 which is fitted around a rim 24 of the pedestal opening 23. Oxygen passing to a nozzle 29 from a cylinder outside the pedestal 14 is directed through the Venturi 28 into the tube 27 and passes, with cooled air it entrains from the box 19, into the canopy 10. Air displaced from the canopy passes to the box 19 through the pedestal and box openings. The pedestal has apertures (not shown) communicating with the outside atmosphere. The canopy-supporting frame 34 is supported by a pillar 35 which is raised or lowered by mechanism 37 within the pedestal 14.

Patent GB-306495-A (GB)
Title: Improvements in transfer mechanism for use in glassware making machines
IPC: C03B35/12
Filed: 1929-02-21
Abstract: 306,495. Capstan Glass Co., (Assignees of McNamara, W. L.). Feb. 21, 1928, [Convention date]. Removing formed articles. - A device for taking-off glassware from the machine by which it has been formed, comprises a pneumatic device for holding an article by suction and transferring it from a mould to a conveyer, the article preferably being inverted while it is being transferred. The device is shown applied to a machine for pressing tumblers which are to be used for packing foodstuffs. Each of the press moulds comprises a body 5, Fig. 2, and a bottom which is fitted to a plunger 6 that slides vertically through the mould table 2. At the take-off station, the plunger 6 is raised by the piston-rod 10 of a pneumatic cylinder 9, thus lilting the glass article 7 out of the mould to the position shown in dotted lines. The transferring- devioo comprises a sleeve 17 rotatable on a vertical shaft 18 and provided at its upper end with a tubular arm on which another tube, 19, is rotatably mounted. The tube 19 carries at its outer end a hollow jaw 23, Figs. 2 and 5, having its inner face shaped to conform to the article 7. The inner face, which may be lined with asbestos, is perforated, and the interior of the jaw communicates, through the arm 19, with a pipe 38 connected to a vacuum tank. A gear wheel 24, secured to the inner end of the tube 19, engages pegs 25 screwed into a stationary collar 26 on the shaft 18. In use, the sleeve 17 is oscillated about the shaft 18 in synchronism with the movement of the mould table 2, either by means of a pneumatic cylinder or by means of a link 29 connected to the mechanism for moving the table. When an article 7 is lifted out of a mould, it is engaged by the jaw 23 and held by suction. The jaw carries the article to a receiving device, shown in Fig. 3, and is inverted during the movement by the engagement of the wheel 24 with the pegs 25. The suction is then released, the article is deposited on a support 44, and the jaw is swung back to its original position. The support 44 is carried by the piston rod 45 of a pneumatic cylinder 46. When it has received an article, the support is lowered by the cylinder 46 and the article is then moved on to a conveyer 52 by a pusher 54 operated by a pneumatic cylinder 57. If an article is not removed, or if a charge of glass is not pressed properly, it is necessary that the mould should be cleared before receiving a new charge. For this purpose, a pneumatic cylinder 64, Fig. 2, is arranged to move a pusher 66 over the mould in the position after the take-off station. In this position the plunger 6 is lifted by a pneumatic cylinder 9<1>, and the pusher 66 removes any glass which may have remained in the mould.
