Abstract: 909,422. Drying film in long lengths. LIPSNER-SMITH CORPORATION. Sept. 8, 1959 [Sept. 8, 1958], No. 13635/61. Divided out of 909,421. Class 34 (1). [Also in Group XX] Apparatus for the non-evaporative drying of film comprises a chamber with a film inlet at one end and a film outlet at the other, means adjacent the outlet end for directing a highvelocity air stream against the film surface, and means within the chamber for shielding the wet portions of the film from the resulting wet air stream. As shown, the drier comprises a chamber 102, the film being led in through a slot 106, and out through a similar slot at the other end. Adjacent the exit slot are air nozzles through which a high-velocity, high-volume jet of warm air impinges on the film strip in a direction opposite to its motion, preferably at about 45 degrees, as indicated generally by lines a. Suitable values for the speed and volume of the air jet, and the film speed, are given. This jet strips the liquid layer from the film, and thus avoids any evaporative drying. Baffles 110 and 112 are arranged so as to prevent the redeposition of the liquid on rearward parts of the film strip. Rapid removal of the spray-laden air from the drying chamber is assisted by connecting an exhaust pump to ports 114. Specification 909,423 also is referred to.

Title: Improvements in braking systems for motor vehicles, and the like
IPC: B60T7/02
Filed: 1927-05-21
Abstract: 289,650. McBride, W. H. May 21, 1927. Controlling different functions by the same lever; brakes, arrangement of, and braking.-A four wheel brake system for motor vehicles is capable of being actuated by a hand lever for ordinarv use and by the clutch pedal at full thrust for emergencies. Each brake comprises two bands c each connected at one end by an eyebolt f to a bracket on the axle and connected at the other end to a, lever i on a shaft g journaled in the bracket. The two shafts g have levers d, e connected together by a rod k having an adjustable abutment m for a spring which bears against an abutment r on the bracket secured to the axle. The springs n of the rear brackets tend to apply the bands to the drums but the cornesponding springs on the front brakes tend to hold the bands off. The upper ends of the forward levers d of the near brakes are connected by rods s<2>, Fig. 7, to levers p<2> on a transverse shaft y which has two other levers w connected to cables v passed around pulleys u on the steering pins of the stub axles and connected to the rear levers d<1> of the front brakes. One of the levers p<2> is formed with a quadrant having a notch which is engaged by a spring-pressed pawl r<2>, Fig. 6, when the rear brakes are off and the springs n of the rear brakes are compressed. The forward end of the pawl is connected to a lever i<2> which can be moved to release the pawl by a link j<2>, lever k<2>, and link l<2>, connected to a trip lever on a hand lever m<2>. When the pawl r<2> is disengaged from the notch the springs n apply the brakes to the rear wheels, and these springs being stronger than those on the front brakes, the front brakes also are applied through the pull on the rods s<2> and cables v. Further pressure can be applied by the hand lever m<z> which is connected by a link n<2> to a lever o<2> on the transverse shaft y. Forward movement of this lever disengages the brakes and allows the pawl r<2> to re-engage its notch. The clutch pedal e<2> is connected by a link f<2> to a lever g<2> having a slotted quadrant h<2> engaging a pin on the lever i<2>. The slot is long enough to allow the clutch normally to be actuated without affecting the lever i<2>, but further pressure on the pedal e<2> moves the lever i<2> and the pawl r<2> is tripped to allow the brakes to be applied by the springs m. A brake pedal may be provided in addition to the brake lever m<2> in which case the, pedal is connected by a link to a, lever loose on the transverse shaft y and having a lost motion connection with a collar on the shaft. The brake bands are lined with the material known under the Registered Trade Mark " Ferodo."

Making pressure vessels.-A method of manufacture-of pressure vessels, e.g. cast alloy valve bodies, for containing high pressure and high temperature fluids, comprises preheating a semifinished vessel to a temperature sufficient to increase its ductility, e.g. 1000‹ to 1200‹ F., which is at least equal to the operating temperature of the fluid to be used therein, subjecting the heated vessel to high internal pressure to effect a permanent deformation of portions of said vessel to redistribute the stresses therein, discontinuing the application of heat and pressure in a manner to prevent reverse elastic flow and thereafter machining the vessel to its finished dimensions. In an embodiment the bores 22 and 28 of a valve body 20 are plugged by cover plates 34, 35 and 36 securely held on seals 37 by split-ring clamps 42. The valve body is mounted on a support 46 in a furnace 44 and a thermocouple 62 is connected to the wall of the valve body. In operation, the valve body is heated to 1200‹ F., which is preferably 200‹ to 300‹ F. over the expected operating temperature, and a valve 52 is opened to admit water into the valve body. The water immediately turns to steam which exerts a high pressure within the valve body. The pressure, which slightly exceeds the operating pressure of the valve body, is controlled by a relief valve 60 and is maintained for a period of one to ten hours to effect a rapid creep of the metal. After prestressing, the valve body is allowed to cool and the internal pressure is not relieved until the temperature has fallen 200‹ F. to 300‹ F. to prevent reverse flow which would destroy the desired stress pattern effected by the heating and pressurizing. Finally, the valve body is machined. U.S.A. Specification 2,117,351 is referred to.
