Granted: 1964-08-14
Abstract: A dichromium trioxide catalyst is made by precipitating hydrous chromic oxide from a solution of a trivalent chromium salt, e.g. by adding sodium or potassium hydroxide, or, preferably, ammonia gas or aqueous ammonium hydroxide, and subsequently heating it to 300-400 DEG  C. for not less than one hour.  For example, aqueous ammonia is added to a heated aqueous solution of Cr(NO3)3.9H2O to pH7, the solution is boiled and filtered hot, the precipitate hot water-washed and, dried by heating under vacuum or in an inert gas stream or in equipment with facilities for steam escape, at 100-200 DEG C.  The partially dehydrated oxide is granulated to 4-20 mesh or pressed to pellets 3 mm. x 10 mm. and subjected to heat treatment at 300-400 DEG C. for a substantial period. The heat treatment may take place in an atmosphere consisting of water vapour and optionally an inert gas for at least two hours. The catalysts are substantially amorphous and have a surface area at least 5m2/g and usually above 50m2/g. Specification 794,075 is referred to.ALSO:Hexafluoroacetone, perfluorochloroacetone or a mixture thereof is made by contacting in the vapour phase at least one perhalogenated acetone containing two to five fluorine atoms and no halogen other than chlorine and fluorine at an elevated temperature up to 500 DEG  C. with a dichromium trioxide catalyst obtained by precipitating hydrous chromic oxide from a solution of a trivalent chromium salt and subsequently heating it to 300 DEG -400 DEG  C. for not less than one hour.  The catalyst may be used in unsupported granular or pelleted form or supported on inert refractory material.  The preferred starting materials are perhalogenated acetones containing two to four fluorine atoms. The process may be operated continuously and the products separated by fractional distillation. In examples using sym-tetrafluorodichloroacetone, 1,1,2 - trifluoro - 1,2,2 - tricloroacetone or pentafluorochloroacetone, the main products were CF3COCF3, CF3COCF2Cl, CF3 COCFCL2 and CF3COCL3 with CF2ClCoCCL3 in addition in the first two examples.

Abstract: 101,899. Thomason, J. Jan. 21, 1916. Pile, cutting; stop-motions.-In velvet, cord, and like pile-cutting devices in which the blade a, Figs. 1 and 2, and its guide bare pivoted at k to a spring-controlled carrier c, thecarrier is held in its operative position by means of a clip e pivoted to the stationary frame d and having a projection g between the fabric and the guide and an extension h adapted to bear against a projection i on the carrier. When the blade pierces the fabric, the fabric moves against the part g to rotate the clip and release the carrier, which assumes tho position shown in dotted lines in Fig. 1. The blade holder b<1>, Fig. 3, is provided with a cam-shaped part b<2>, which is eccentrically disposed with regard to the pivot k and normally rides on the fabric and tends to keep the blade clear thereof. The guide and its blade pass through a slot in the holder and are secured by means of a slotted bolt b<3> and nut b<4>, so that the blade or guide can be readily detached or replaced by another. Abnormal motion of the blade may cause an electric circuit to be broken or completed to stop the motion of the fabric, and in this case the pivot k carries an arm m adapted to make contact with an adjustable stationary contact-piece n. The handle portion g of the device is pivoted to a part r having sockets s, t, which, when the cutter is in the operative position, can be placed on terminals of the controlling-circuit, the sockets being connected by insulated wires to the stationary frame d and to the contact-piece n respectively.

Title: Railway car coupler
Inventor: LIVELSBERGER KENNETH VINCENT
IPC: B61G3/16
Filed: 1964-01-14
Abstract: 1,030,481. Railway vehicle automatic couplings. AMSTED INDUSTRIES Inc. Jan. 14, 1964, No. 1590/64. Heading B7T. A coupler shank 3 provided with a pivot pin hole 6, Fig. 1, a bearing block 8 and a spherical end surface 7 for universal movement mounts a head provided with upper and lower sections 5, 10, Fig. 2, angled at 45 degrees to the horizontal and having walls 9, 11 spaced apart by walls 12, 13, 14 and 24 defining a throat 16 and a chamber 26, Fig. 4, containing a gravityoperated sliding lock 27 shaped to engage with a similar lock of a mating coupler. The lock, Figs. 6, 7, has a slot therein accommodating a cranked latch 33 pivoted to the lock at 36 and has a further slot containing a lever 34 pivoted to the lock at 37 and having a bevelled edge to engage the latch. When in the operative position, Fig. 4, a lug 28 on the lock extends through a slot in the wall 24 to engage a stop shoulder 31. The head is provided with hollow guide wings 39 pivoted at 41, the wings being retractable against springs 42 to abut the front walls 14, Fig. 4, when abutted by aligning walls 19, 21 projecting from a mating head and defining wing pockets 22, 23, Fig. 2. In the retracted or coupled position, Fig. 7, a shoulder 43 on a wing 39 is positioned close to the latch 33 to prevent accidental displacement of the lock 27. When coupling up, the lock 27 which is free of the shoulder 43 on the extended wing 39 is first moved up by the mating coupler lock to pass the mating lock and allow it to enter the throat 16. The lock then moves downwardly to trap the mating lock. The final coupling movement causes the wings to press back and move a shoulder 43 to a holding position behind the latch 33. When uncoupling, the lock is retracted into its housing by manual operation of a lever and rod mechanism, Figs. 11-13 (not shown) which rotates a rotor 40 and an arm 38, Fig. 6, and the lever 34. By means of its bevelled edge, Fig. 7, the lever 34 first retracts the latch 33 away from the shoulder 43 on the wing 39 and then moves the latch and lock into a lock-set position within the chamber 26. After uncoupling, the lock is free to move downwardly again and the springs 42 pivot the wings 39 forwardly. To permit shunting without coupling the rod mechanism may be further moved and latched to hold the lock entirely withdrawn from the throat.
