Title: Improvements in the manufacture of artificial threads by the wet spinning process
IPC: D01F2/28
Filed: 1931-09-03
Abstract: Artificial cellulose acetate threads are made by the wet stretch-spinning process from a solution of the acetate in a medium consisting of a mixture of non-solvents one of which, at least, is soluble in the precipitating bath.  This soluble component is preferably used in quantity not substantially exceeding that required to produce dissolution of the acetate, so that precipitation readily occurs.  Pure water may be used as the precipitating liquid without producing white threads.  In an example, 8-10 parts of alcohol are added to a mixture of 10 parts of cellulose acetate and 40 parts of dichlorethylene, and the solution spun, with stretching, in water at 40-50 DEG  C.; at 100 metres per minute and with the employment of nozzles of 0.1 mm. diameter, threads of less than 0.3 denier may be spun.  Softening agents, resins, other cellulose derivatives, and the like, may be added to the spinning solution.

Abstract: 1,255,459. Isomerizing alkylaromatics. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 26 May, 1970, No. 25091/70. Heading C5E. Alkyl aromatic hydrocarbons in which the alkyl groups are C 1-4  are isomerized at a temperature below 440‹ C. with a catalyst comprising an acidic refractory oxide and a hydrogenating/dehydrogenating metal component, and in the additional presence of both hydrogen and steam, the amount of steam being in the range 100-1500 p.p.m. (vol.) based on hydrogen plus hydrocarbons. Many suitable oxides and oxide mixtures are referred to, including zeolites; preferred are (a) silica/alumina containing 10- 70 wt. per cent alumina, and (b) alumina containing 1-3 wt. per cent fluorine. Preferred metal components are Ni, Co, Pd or Pt. Both alkyl benzenes and alkyl naphthalenes may be isomerized, but the process is particularly applied to C 8  aromatics, i.e. xylenes and ethyl benzene. In the latter case conditions may be such that some hydrogenation takes place so as to provide 1-50 wt. per cent C 8  naphthenes in the reaction product.

Patent GB-599135-A (GB)
Title: Improvements in or relating to directional radio systems
IPC: G01S1/02
Filed: 1944-12-16
Abstract: 599,135. Radio direction-finding ; directive radio systems. SHAW, W. L., and SYKES, J. Dec. 16, 1944,'No. 25280. [Class 40 (v)] A directional radio system with two or more receivers or transmitters has a common directional aerial system comprising elements having mutually perpendicular axes of maximum response connected to the field coils of a spinning goniometer system which has two synchronously driven search coils with 90 degree electrical separation. The search coils may either be two mutually perpendicular coils on the same shaft in the same goniometer or they may be in separate goniometers but with the required electrical separation. The inductances and numbers of turns of the search coils need not be equal but electrostatic screening is required. A direction finder in which the aerial system supplies four receivers, Fig. 1, comprises a goniometer with its field coils connected to aerial elements at NS and EW. Two mutually perpendicular search coils S1 and S2 are rotated inside the field coils and connected through slip rings SB1 and SB2 to synchronously driven distributors RS1 and RS2 which supply two receivers alternately, each for half a revolution. The four receivers R1, R2, R3 and R4, have sense aerials connected through terminals A and B and are provided with switches for selecting circular, figure of eight, or cardioid polar diagrams. Each receiver has a cathode ray indicator for displaying bearing and passes thereto a series of pulses for triggering the horizontal sweep twice for each revolution of the search coil system. These pulses are supplied from one of synchronous pulse generators P1, P2, P3 and P4 selected at the receiver. The audio output of the receiver is applied to the vertical deflection means of the cathode-ray tube and provides a pattern with a minimum at a position along the trace corresponding to bearing. The horizontal axis of the tube screen may carry a scale marked in degrees, 0‹ to 180‹. above the trace and 180‹ to 360‹ below. A sense switch choosing oppositely phased triggering pulses and whose two positions correspond to the upper and lower scales may be fitted to the receiver to resolve sense ambiguity when reception is over the cardioid diagram. Fig. 2, (not shown), illustrates the patterns obtained for incoming signals from a number of directions. A modification involving two goniometers each having two mutually perperidicular search coils and which provides standby channels available in the event of a breakdown of one goniometer is also described.

Title: Improvements in or relating to wheeled trailers for transporting and launching boats

Filed: 1960-07-21
Abstract: 912,889. Boat transporting and launching devices. TOYE, D. H. July 21, 1960, No. 25378/60. Class 113. [Also in Group XXXII]. A boat trailer which may be tipped about its wheels for launching and loading is provided with fore and aft cradles 10, 30, rollers such as 15, 22 spaced longitudinally of the trailer, means for raising and lowering the after roller 22, and a winch 40. An inverted channel 7 is rigidly connected between members 3 and 5 of the frame 1, and a drawbar 9 is pivoted at 8 to the channel 7 and releasably connected via lugs 11, 13 and a spring biased locking pin 12 to the member 3. The roller 15 is mounted on an upright 16 which is vertically adjustable with respect to the bar 9, and the roller 22 is mounted in a bracket 23 fixed on a bar 21, which bar may be rotated to lift or lower the roller 22 by movement of a link 25 actuated by pivoting an arm 26 about a pin 28. In operation a boat is supported for transport by the cradles, but when the boat is to be launched it must be supported by the rollers alone, so the handle 26 is operated to raise the roller 22 and lift the boat from its cradle 30. The pin 12 is then withdrawn so that the weight of the boat causes the frame 1 to tilt rearwardly about its wheels. This tilting causes the relative positions of the cradle 10 and roller 15 to change, see Fig. 4, so that the roller 15 lifts the boat from the cradle 10.
