Abstract: 508,976. Gravity - feed lubricating ; visible feeds. TECALEMIT, Ltd. Jan. 10, 1938, No. 768. Convention date, Jan. 11, 1937. [Class 12 (iii)] An indicator for lubricating or liquid-dispensing apparatus comprises a tube 102, Figs. 3 and 4, both ends of which are at the same gas or air pressure. Liquid is supplied to a receiver 100 at the upper end of the tube 102 at a rate less than the maximum rate at which liquid will flow through the tube under the gravity head represented by the length of the tube, whereby the liquid will entrap bubbles of air and will, under the action of gravity, flow downwardly through the tube in short columns separated by air. As shown in Fig. 3, a gear pump 52 supplies oil in excess to a reservoir 32 from a supply 20: The level in the reservoir 32 is kept constant by an overflow 74. A series of capillary tubes 76 lead oil from the reservoir 32 to capillary grooves 98 down which the oil flows to the receivers 100 and thence through the tubes 102, passages 108, 110 to pipes 112 leading to the bearings. The rate of oil flow can be varied by turning a nut 88 to vary the inclination of a capillary tube 76. In a modification, oil flows from a reservoir 150, Fig. 14, to a manifold 186 through an orifice 192 controlled by a valve 190. From the manifold 186 the oil flows through valvecontrolled passages to the sight feed tubes 214. A reservoir 182 supplies oil to the reservoir 150 on the bird fountain principle. A rod 172 on the filling cap 168 normally holds open a valve 176 connecting the reservoirs 150, 182. In another modification, a pump 240, Fig. 16, supplies oil to a manifold 250. Between each sight-feed tube 262 and the manifold 250 is a. flow control device comprising an adjustable screw-threaded plug 254 accommodated in a smooth cylindrical bore. The oil passes along the helical passages formed by the screwthread on the plugs 254, through ducts 258 to receivers 260 and so to the sight-feeds 262.

Title: Conditioning the surface of formed metal articles
Inventor: AWAD SAMI B
IPC: C10M107/34
Filed: 1995-03-16
Abstract: Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition as described above, and of other similar surface friction reducing treatments for aluminum containers, may be advantageously increased by adding a biocidal agent, preferably hydrogen peroxide, and a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.

IPC: C07C11/02
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To stably produce α-olefin oligomers, mainly 1-hexene starting from ethylene in high yield and selectivity by using a specific catalyst with industrial advantage. SOLUTION: In the production of α-olefin oligomers, a catalyst prepared from at least three components, namely a chromium-containing compound, an alkylaluminum compound and a halogen-containing compound is used. As a chromium-containing compound, is used a chromium-pyrrolyl bond-containing compound prepared by reaction of a pyrrole compound selected from a pyrrole which may has a substituent or its metal salts with a chromium salt in a (halogenated) hydrocarbon solvent. This chromium-containing compound is brought into contact with an alkylaluminum compound in the presence of an α-olefin to prepare the catalyst for this invention.  According to this process, instead of pyrrole which is poor in storage stability, this compound having a stable chromium-pyrrole bond is used to prepare the catalyst and objective α-olefin oligomers are obtained without complicated operations.
