Title: Improvements in fluid flow control valves of the screw down type
Inventor: BOWEN HENRY WILCOX
IPC: F16K1/04
Filed: 1955-04-01
Abstract: 803,585. Valves. HIGH -PRESSURE COMPONENTS, Ltd. March 21, 1956 [April 1, 1955], No. 9571/55. Class 135. A manually operable screw down two-way flow control valve comprises a casing 1, Fig. 1, having a conical valve seat 4 which receives a cup-shaped closure member 5. The closure member 5 is loosely connected to the part spherical end 11 of the actuating spindle 6, e.g. by four balls 14 each of which engages on an annular groove 13 in the end 11 of the spindle and is located in a hole 15 in the wall of the closure member by a collar 16. The closure member 5 is thus freely movable to seat correctly on the seat 4. A sealing gland 7 is compressed into sealing engagement with the spindle 6 by a nut 18 which screws on to a separate extension 8 of the valve casing. When the valve is fully open a washer 21 is gripped between a flange 17 of the casing extension 8 and a flange 22 of the spindle 6 to enable ready replacement of the sealing gland 7.

Title: Synthetic resins and their manufacture
IPC: C08G65/40
Filed: 1936-04-01
Abstract: Resinous materials are prepared by reacting together in the presence of an alkali but in the absence of an amine a dihalogeno derivative of the general formula Hal--X--Hal wherein X represents --CH2-- or an aliphatic hydrocarbon chain which may be broken by an ether linkage, and a polynuclear dihydric phenol containing an alkyl-substituted cyclohexane ring and in addition two carbocyclic nuclei, each of which carries a phenolic hydroxyl group.  The reaction may be effected under pressure in the presence or absence of a solvent. Suitable phenols include the following derivatives of 1 : 1-bis-(4-hydroxyphenyl)-cyclohexane the substituent being in the cyclohexane ring 4-methyl, 4-tert-amyl, 4-tert-butyl, 4-tert-heptyl, 3 : 3-dimethyl, 3 : 5-dibutyl, and 3-methyl-4-ethyl and 1 : 1-bis-(4-hydroxy-2-methyl)-3 : 5-dimethyl cyclohexane.  Alkalies include alkali metal and alkaline earth metal hydroxides such as sodium, potassium and lithium hydroxide.  In examples, 1 : 1-bis-(4-hydroxyphenyl)-4-methylcyclohexane or the corresponding 3 : 3-dimethyl and 4-tert-amyl cyclohexane derivatives are condensed with b -b <1>-dichlorodiethyl ether in the presence of water and sodium hydroxide.  The resins may be purified by mixing them with a small amount of toluene, neutralizing the product with hydrochloric acid and washing with hot water.  The products may be used in the manufacture of unsupported films, fibres, liners, glass substitutes such as windscreens, nursing bottles, household dishes, and electrical appliances, dentures, adhesives, pipe stems and kitchen furniture.  Specification 433,452 is referred to.  1 : 1-Bis-(4-hydroxyphenyl)-4-methylcyclohexane and the corresponding 3 : 5-dimethyl and 4-tertamyl cyclohexane derivatives are prepared by condensing phenol with 4-methyl-, 3 : 5-dimethyl- or 4-tert-amylcyclohexane in the presence of hydrochloric acid.

Title: Process for the production of solid titanium-trichloride catalyst
Inventor: SHIGA AKINOBU
IPC: B01J27/08
Filed: 1983-03-31
Abstract: TiCl4 is reduced with an organic Al cpd. of R1nAlY3-n (wherein R1 is a 1-18C hydrocarbon gp, Y is halogen or H and n is 1 to 3) at -50 to +50 deg.C in an inert solvent to provide a suspension of TiCl3 catalyst compsn. The suspension is opt. heat-treated at a temp. of 150 deg.C for 0.5-6 hrs. The solid TiCl3 catalyst compsn. is sepd. from the suspension and washed with an inert hydrocarbon solvent several times. The TiCl3 catalyst compsn. is then reacted with a mixt. comprising a halogen or interhalogen cpd. of XX'a (wherein X and X' are the same or different and Cl, Br or I and a is 1 or 3) (10 power -5 - 5 x 10 power -2 mol. per g of the TiCl3 catalyst compsn) and ether cpd. of R2-O-R3 (wherein R2 and R3 are each independently 1-10C alkyl) 10 power-4-0.03 mol. per g of the TiCl3 catalyst) at 20-150 deg.C opt. in the presence of another electron donor (10 power -4 - 10 power -2 mol per g of the TiCl3 catalyst) in an inert hydrocarbon solvent. The reaction mixt. is sepd. into the liq. and solid phases and the solid phase is washed initially with an aliphatic hydrocarbon solvent and then with the aliphatic hydrocarbon solvent or other inert hydrocarbon solvent. - If the sepd. solid catalyst compsn. is washed with an aromatic hydrocarbon, the liq. solid mixt. cannot be sepd. by filtration resulting by insufficient sepn. The initial washing of sepd. solid catalyst with an aliphatic hydrocarbon facilitates the washing of catalyst compsn. to control contaminants and large particles of catalyst and to inhibit the formation of tough and large polymer particles which plug the catalyst feeding lines and resin discharging lines.(0/0)
