Patent GB-849081-A (GB)
Title: A process for the production of polycarbonates
Inventor: DALTON LESLIE KENNETH
IPC: C08G64/08
Filed: 1957-04-10
Abstract: Polycarbonates, useful in the manufacture of moulding compounds, films and surface-coating compositions, are made by condensing a diphenylol sulphone with phosgene in the presence of a hydrogen chloride binder (e.g. a metal hydroxide or carbonate, an organic amine or a quarternary amine).  Preferably condensation is effected under heterogeneous conditions by dissolving the diphenylol sulphone in excess aqueous sodium hydroxide solution and adding the phosgene dissolved in an organic solvent (e.g. methyl chloride, methylene chloride or trichloroethylene) whilst at the same time adding more aqueous sodium hydroxide solution to maintain an alkaline pH value. The polycarbonate may be recovered from the reaction mixture by adding an emulsion breaker (e.g. an aliphatic alcohol) and pouring the non-aqueous phase into ethanol to precipitate the polycarbonate. An example describes the preparation of a polycarbonate of 4,41-dihydroxydiphenyl sulphone.  Specification 772,627 is referred to. p   Reference has been directed by the Comptroller to Specification 808,846.

Patent GB-1320053-A (GB)
Title: Apparatus for moistening a mass of soil
IPC: A01G27/04
Filed: 1971-04-28
Abstract: 1320053 Watering plants N CALTAGIRONE 28 April 1971 [28 April 1970] 12022/71 Heading A1E A device for watering plants comprises capillary means 8 for supplying water from reservoir 6 to soil T, capillary tubes 3 connecting the reservoir with the atmosphere, and an auxiliary reservoir 1 linked to the main reservoir by a central channel 4, the tubes 3 communicating with the central channel and via passages 13, 12, 10, with the atmosphere. The removal of water by capillary action through tubes 8 causes a reduction in pressure in the air space of reservoir 1 until an equilibrium is reached between the capillary suction and the reduced pressure, stopping the flow out. When moisture has evaporated from the soil suction resumes and the reduction in pressure once more increases, until atmospheric pressure is able to overcome the surface tension resistance of the water in capillary tubes 3 and air can enter the reservoir. The reduced pressure can therefore be maintained at a fixed value and the amount of moisture absorbed by the soil be governed by the width of the tubes 3, since the narrower the tubes the greater the surface tension resistance. In a modification, capillary tubes of different widths radiate from the central channel 4, the amount of moisture absorbed by the soil being adjusted by a rotatable valve sleeve connecting them selectively with the atmosphere. In further embodiments (Figs. 6-10, not shown) the auxiliary reservoir is omitted and a capillary orifice (35, 41) is inserted below the level of the water on the end of a hollow sleeve (34, 44) removably located in an upper wall of the reservoir. In Fig. 11 capillary means 65 1 ..65 3  communicating with the reservoir R are buried in separate masses of soil, the regulating capillary passages being provided by porous capillary material 62.

Abstract: 973,873. Fluid operable lifting apparatus. JOSEPH LUCAS (INDUSTRIES) Ltd. March 21, 1963 [March 29, 1962], No. 12045/62. Heading B8J. In a fluid-operable piston and cylinder unit for lifting apparatus, fluid can flow to and from a cylinder 1 by way of a port 3 and a pipe 4. The port is divided into three coaxial portions of different diameters. A flanged and stepped plug 5 has a spigot-like stem 5a which is surrounded by the skirt of a hollow piston 7. The plug also has an axial passage 6 which communicates with radial passages in the stem 5a. An annular seating 5b at the end of the stem is adapted to close a central hole 7a in the piston 7 and a compression spring 8 normally urges the piston 7 away from the stem seating 5b. In use, fluid can flow to or from the cylinder 1 under control of a valve (not shown). However, should the pressure in the cylinder exceed the pressure in the pipe 4 by more than a predetermined amount, due, for example to a pipe failure or to the piston 2 descending at excessive speed under load, the piston 7 will close against the seating 5b and prevent or permit only slow escape of fluid from the lower end of the cylinder.

Filed: 1966-03-18
Abstract: 1,170,244. Fluid-pressure servomotor systems; fluid regulation. DOWTY FUEL SYSTEMS Ltd. April 5, 1967 [March 18, 1966], No. 12113/66. Headings G3H and G3P. A speed governor comprises a fluid switch having a power nozzle 1, outlets 2, 3 and control nozzles 4, 5, there being a feedback from outlet 2 to control nozzle 4 including a delay device in the form of a transmitter nozzle 7 and a receiver nozzle 8 at opposite ends of a space 9 vented at 10. The control nozzle 5 receives pulses at a frequency proportional to the engine speed from receiver nozzle 13 co-operating with a transmitter nozzle 12. The jet from the latter is periodically disturbed when a baffle 18 rotating at engine speed allows a jet to issue from nozzle 16. The control point of the governor is determined by the pressure of the power jet and the distance between nozzles 7, 8, and is varied by varying the power jet pressure. When the engine speed equals the selected speed control pulses occur at equal time intervals and power jet pulses of equal volume flow alternately down outlets 2, 3 to opposite sides of a piston 22 having an extension 24 serving as a throttle valve. The restricted outlet 28, from the left-hand end of cylinder 21 has an effect equal to the combined effects of restricted outlet 27 and nozzle 7. When the speed varies, the frequency of control jet from nozzle 5 varies and the flow rates in outlets 2, 3 differ to cause displacement of piston 22. The jet from nozzle 5 over-rides a jet from nozzle 4.
