Title: Process for the modification of solutions of oil modified resins
IPC: C09D167/08
Filed: 1951-10-22
Abstract: Solutions of oil-modified resins (e.g. in mineral spirit, or a mixture thereof with butanol) adapted for use in lacquers or paints or lacquers or paints containing such solutions are modified by addition of a metal-containing synthetic resin prepared according to Specifications 718,283, 718,284 or 718,359 in quantity less than that of the oil-modified resin.  The synthetic resins may be added as a solution in an organic solvent. Oil-modified resins to which the metal-containing resins may be added are glyceryl-phthalates, and phenol-aldehyde resins which have been modified with oils such as lineseed oil, soya bean oil, castor oil or wood oil.  The mixtures may be warmed to aid solution.  In examples: (1) a resin from aluminium butylate and acetoacetic ester is added to a solution in a mixture of mineral spirit and butanol of a linseed oil-modified glyceryl-phthalyl resin; (2) a resin from ferric butylate and acetoacetic ester is added to a solution of a castor oil-modified glyceryl phthalyl resin in a mixture of mineral spirits and butanol; (3) a resin from aluminium butylate and diethyl malonate is added to a mineral spirit solution of a soya bean oil-modified glyceryl phthalyl resin; (4) a resin from aluminium butylate and formyl acetophenone is added to a xylene solution of a castor oil modified phenol-formaldehyde resin; (5) a resin from aluminium chloride and acetoacetic ester is added to a solution in mineral spirit-butanol mixture of castor oil modified glyceryl phthalyl resins.  Example (6) is similar but the added resin is modified by blowing air through it as described in Specification 718,284, and in example (7) the added resin was modified by reaction with phthalic anhydride as described in Specification 718,359.  Specifications 698,838, [Group III], and 734,677 and U.S.A. Specification 2,169,577 also are referred to.

Title: Direction finder
IPC: G01S3/14
Filed: 1974-06-05
Abstract: 1475414 Radio direction-finders LICENTIA PATENT-VERWALTUNGS GmbH 5 June 1974 [6 June 1973] 24895/74 Heading H4D In an arrangement for automatically finding the directions of incidence of a plurality of waves having different carrier frequencies within a predetermined band an antennae system provides directionally dependent output voltages, a sampling device provides instantaneous values of the voltages at predetermined successive intervals, and a computer which is arranged to receive the instantaneous values is programmed to determine therefrom the directions of incidence of the waves. The invention is described in terms of two waves received by an Adcock direction-finding antennae system but is treated as being of general application where voltages are produced which are phase and amplitude dependent on the wave directions. An appropriate number of samples is required for more than two waves. As described, an Adcock aerial system 1 is connected to a three-channel Watson-Watt type amplifier 5 which provides output voltages respectively proportional to the amplitude of an incident wave, to the amplitude multiplied by the sine of the azimuthal angle of incidence, and to the amplitude multiplied by the cosine of said angle. With two waves incident upon the aerial system, the voltage relationships are: where z, y, x are the voltages at time t in the channels 2, 3, 4, A 1 , A 2  are proportional to the amplitudes of the two waves, # 1 , # 2  are their angular frequencies, # 1 , # 2 , their phases, and α 1 , α 2  their angles of incidence. It is demonstrated mathematically in the Specification that if the instantaneous values of z, y, x are determined at times t=0 and t=t 0 , then the values of α 1 , α 2  may be calculated. The time scanning is effected by a device 6, which is controlled over a line 9 by a computer 8. A sequence of pulses is obtained, which are digitized in an analogue/ digital converter 7 and fed to the computer. A conventional display device may be paralleled across the outputs of the amplifier 5.

Class 85 [Also in Groups XXII, XXIII and XXXVI] In a well drilling assembly, a plurality of strings of drill tools are each supported from one of a number of arms on a pillar derrick and each tool string has incorporated therein a motor which, with the means for raising and lowering the string, is automatically controlled by electrical contacts incorporated i n said structure. The upper unit of the drill string comprises a centring and clamping unit the base of which is recessed to receive a pin formed on the casing of an electric motor for driving the bit. On the bit encountering the bottom, electrical switches 28 are operated as the assembly slides down around the pin 23 towards the drill, so starting the drill motor and stopping the winch. The drill motor is stopped and the winch restarted when contact 27 is operated as the pin descends in the assembly. The drill string is raised until a switch is tripped to stop the winch and another string is moved into position for the next operation. The borehole casing is held by jaws in a sleeve externally threaded and engaging in complementary internal threads formed in a sleeve externally threaded to engage the base. Centrifugally operated internal pipe cutters, cam operated side sampling tools, and percussive drills are provided on the drill shaft. The Specification as open to inspection under Sect. 91, describes also how each string is supported from one of a number of arms formed on a rotatable sleeve on a pillar that is mounted on a portable base and carries a pulley over which passes the main portion of the supporting cable. The connection between the main portion of the cable and that portion supporting the drill string is formed as an electrical socket the two halves being connected together on a sealing ring. This subject-matter does not appear in the Specification as accepted.
