Also rigidly mounted on this shaft'is an arm 28 which is pulled downward by a spring 42. Mounted on the free end of the arm 28 is an arm 29 having a notch 31 which is engageable with a pin 33 mounted eccentrically on a plate 32 attached to the shaft 4 of the roller 2. When it is desired to disengage roller 3, arm 29 is moved into the path of pin 33 so that the arm 28 is pulled upward against the spring 42 and forces upward the rods 26 supporting the roller 3. The engagement of arm 29 with pin 33 is effected by a push button 41 which moves arm 29 against a spring 35 through a pivoted lever 38, as the arm 28 is pulled up a spring 36 thereon actuates a micro-switch 37 to stop the motor and a spring catch 52 engages a recess 53 in the disc 32 to lock the rollers. To restore the roller 3 to operative position the button 41 is pressed again to move spring 36 away from micro-switch 37 to restart the motor whereupon pin 33 disengages from arm 29 and spring 42 pulls down arm 28. In a modified arrangement separate micro-switches are provided for stopping and starting the motor. Reference has been directed by the Comptroller to Specification 831,172.

Abstract: 1310728 Polyurethane coating DUNLOP HOLDINGS Ltd 9 Oct 1970 [9 Oct 1969] 48063/70 Heading B2E [Also in Divisions B5 and C3] Textile woven or non-woven fabrics, e.g. of nylon, rayon, polyester or polyacrylonitrile may be coated with polyurethane emulsions in an anionic surfactant-containing aqueous medium having a pH of less than 4.0. It is stated that such emulsions may be provided by dipping or spraying, and that metal, wood, glass or concrete may be so coated. An adhesion-promoting composition may be applied first to the fabric, which composition may be an emulsion similar to the final coating emulsion. The emulsion on the fabric may be treated with an aqueous formaldehyde solution or formaldehyde gas generated at elevated temperatures from one of its unstable precursors. Alternatively formaldehyde or a formaldehyde donor may be added to the emulsion before coating. In a specific Example a nylon 6 woven fabric is coated with various polyurethane emulsions. The fabric is first impregnated with a dilute emulsion to provide an adhesive base and allowed to air dry. This impregnation may be followed by the application of a methoxy-methylolated nylon applied from an alcohol water solution before application of the polyurethane emulsion. The emulsion is then fused at elevated temperature and the coated article may be treated with formaldehyde by exposure to formaldehyde gas in equilibrium with solid para-formaldehyde at 80‹C.

Abstract: 1533736 Seals INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH 22 Nov 1976 [22 Nov 1975] 48678/76 Heading F2B A sealing arrangement for the longitudinally movable control spindle 1 of a valve (not shown) of a vessel (not shown), e.g. a pipe-line containing liquid sodium, which solidifies under ambient conditions, comprises a standby permanent seal packing 10 which is axially spaced along the spindle 1 from a housing 5, 6 having cooling fins 7 and affording a first region which communicates with the interior of the vessel so that liquid sodium in the vessel can enter that region to be cooled and thus solidify to form a main freeze seal in a gap between the housing 5, 6 and spindle 1. The axial spacing "A" between the main freeze seal and the standby permanent seal is the same or greater than the total longitudinal movement of the valve spindle. The main freeze seal may be melted (for valve operation) by supplying liquid sodium via a line 12 to a chamber 8 whereby the solidified sodium of the main freeze seal formed in the gap between the housing 5, 6 and spindle is melted and washed back through the gap into the vessel, a safety gas, e.g. argon, which is unreactive with sodium being conveyed to chamber 8 via a line 13, to prevent the formation of such oxides or other reaction products of sodium in the seal itself. Additionally, a further sealing gas supplied through a connection 11 prevents liquid sodium from reaching the seal packing 10 when the freeze seal melts. The seal packing 10 may be of asbestos and graphite. The arrangement is used in fittings for use in liquid sodium cooled nuclear energy plants.

Patent GB-1554098-A (GB)
Title: Tubular projectile
IPC: F42B8/12
Filed: 1977-11-30
Abstract: The projectile consists of a tubular body (10), of a cap (16) which breaks at the start of the shot, a delivery casing (14) which detaches at the exit of the gun, and a forcing belt (12). At the front end, the internal and external surfaces of the body (10) are conical and delimit a leading edge whose angle is between 5 DEG  and 15 DEG . The passage cross-section inside the body decreases from the front towards a cylindrical constricted region, the ratio between these passage cross-sections in the constricted region and at the entry being at least 0.65, but less than 1, and the ratio between the maximum wall thickness and the half-calibre of the projectile being between 0.18 and 0.45. The conditions of flow in the tubular body are such that the drag is low in a first part of the trajectory, but increases sharply when the Mach number has fallen to a particular value, which makes the projectile particularly useful as a training projectile. <IMAGE>
