Title: The pentachlorophenyl ester of trichloroacetic acid
IPC: C07C69/63
Filed: 1952-10-22
Abstract: The invention comprises the pentachlorophenyl ester of trichloroacetic acid, and the manufacture thereof by reacting an alkali metal pentachlorophenate with at least an equimolecular proportion of trichloroacetyl chloride.  The reaction is advantageously carried out at a temperature between 20 DEG  C. and the refluxing temperature of the mixture, preferably at 20-60 DEG  C. The product is useful as a soil sterilizer, a plant growth regulator or an intermediate for more complex compounds.  In an example, trichloroacetyl chloride is added gradually to a stirred solution of sodium pentachlorophenate in acetone.

Abstract: 658,772. Wire compensators. NEATE BRAKE CONTROLS, Ltd. Oct. 12, 1948, No. 26565. [Class 105] [Also in Groups XXIV and XXXIV] A device for automatically taking up slack in a system, such as a brake-applying mechanism, in which a cable is used to transmit movement from a control member, comprises an operating lever 7, a drum 9 to which an actuating cable 14 is secured, a ratchet-wheel 10 on the drum 9 co-operating with a pawl 12 on the lever 7 and a further ratchet-wheel 15 having a lost-motion connection 19, 20 with the drum 9 and co-operating with a detent pawl 17. The arrangement is such that on normal movements of the lever 7 the ratchet-wheel 15 is not actuated by reason of the lost-motion connection but on further movement due to slack in the cable 14 this lost-motion is taken up by one end of slot 20 engaging pin 19 and the disc 15 moved forward one or more teeth over the pawl 17. On the return movement of the lever 7 the other end of slot 20 contacts the pin 19 on wheel 15 which is held by pawl 17 so that the pawl 12 of lever 7 rides over the teeth of ratchet-wheel 10 and engages in a fresh relative position thereto in which the slack in the cable is absorbed.

Abstract: 871,473. Hydraulic presses. SCHON & CIE G.m.b.H. Aug. 28, 1957 [Sept. 11, 1956; Feb. 26, 1957], No. 27065/57. Class 69 (2). [Also in Group XXVIII] A two-stage hydraulic pump, comprising a pump N and a pump H particularly for feeding an hydraulic press and of the type in which the pump N supplies pressure liquid directly to the press at low pressure until such time as the pressure in the press builds up, after which the pump N acts as a feed pump for the high-pressure pump H, is controlled by a valve V which has an inlet 3 connected to the outlet of the pump N and an inlet 25 connected to the outlet of the pump H; the inlet 3 is connected through a non-return valve 4 to a control valve S and the inlet 25 is also connected to the control valve S the outlet from the control valve being connected to a return passage 7 in the valve V. A valve 9 in the inlet 3 is arranged to be opened when the high pressure in the passage 25 and acting on the piston 10 reaches a predetermined value. When the valve 9 opens the valve 4 closes and liquid passes into a chamber 12 which is connected to a further chamber 14 having a spring- controlled outlet valve 17 or a throttle passage which therefore controls the pressure in the passage 3. Further increase of pressure in the passage 25 acts on a piston 27 connected to a spring-loaded piston valve 15 to move the piston and thereby open the chamber 14 to the passage 7 whereby the outlet from the pump N is wholly returned to the reservoir. In a modification the valves 9, 17, 15 are arranged on parallel axes.

Abstract: 1,143,137. Bottling etc.; endless conveyers. A. DI SETTEMBRINI. 17 June, 1966 [28 June, 1965], No. 27236/66. Headings B8A and B8T. Bottles 1 travel on an endless conveyer 2 towards a working station, e.g. where they may be filled from a reservoir 3, and accumulate against a stop 8, while being laterally supported by guides 10. When sufficient bottles have accumulated the stop 8 is withdrawn, and a second stop 11 is directed into the path of the released bottles downstream of the working station. When the leading bottle has reached the stop 11 a horizontal support plate 13, which may have a bevelled leading edge, is pushed under the bottles, and individual bottles are located for filling by vertical partitions 14 on the support plate 13. The stop 8 is then directed back over the conveyer 2 to intercept further bottles. The reservoir 3, which may be of the constant-level type filled through supply pipe 3a, is then lowered and nozzles 7 equipped with closing valves enter and fill the bottles. On completion of the filling process the reservoir 3 is raised and the support plate 13 and stop 11 are withdrawn, the filled bottles being deposited back on the conveyer 2 which carries them away. Capsuling or sealing of the bottles may also be performed while they are held by the plate 13. In an alternative form the reservoir 3 is stationary, and the support plate 13 can be raised vertically to lift the bottles into the filling position. Control of the stops 8, 11, plate 13 and reservoir 3 is through pneumatic pistons and cylinders operated by cams (19, 21, 22, 23), Fig. 1 (not shown), on a shaft (16) driven in synchronism with the conveyer (2).

Abstract: 880,413. Oxidizing asphalt. ESSO RESEARCH & ENGINEERING CO. Aug. 27, 1958 [Oct. 24, 1957], No. 27493/58. Class 55 (2). Petroleum asphalt is catalytically oxidized by being air blown in the presence of a liquid readily-dispersible reaction product of an oxide or sulphide of phosphorus and a hydrocarbon boiling above 300‹ F. and having one or more substituents comprising at least one carboxyl group, hydroxyl group or carbonyl group. The hydrocarbon may be an organic acid having from 12 to 22 carbon atoms with or without an additional hydroxy group, or a compound containing double bonds, e.g. linseed oil, oleic acid and tall oil. Alternatively, the substituted hydrocarbon is a component of a mixture of oxygenated organic compounds produced as still bottoms of the oxo reaction in which hydrogen, carbon monoxide and an olefine having 2-15 carbon atoms are contracted at elevated temperatures and pressures in the presence of a carbonylation catalyst to produce an aldehydic compound which is subsequently hydrogenated to the corresponding alcohol and the major proportion of C 3 -C 16  alcoholic component is thereafter distilled off leaving the aforementioned still bottoms. Specified phosphorus compounds are phosphorus trisulphide, pentasulphide and pentoxide. Examples are given.
