A method of treating polyethylene to improve its optical properties involves forming a mixture of molten polyethylene and an aluminium alcoholate of the formula where R and R<SP>1</SP>, which may be the same or different, are aliphatic radicals containing from 1 to 6 carbon atoms and n is 1 or 2, allowing the resulting mixture to solidify and contacting the solidified mixture with an aqueous reagent (water or water containing 2-ethoxyethanol) at a temperature of from 60‹ C. up to, but not including, the melting point of the polyethylene in the mixture. Aluminium trimethylate, triethylate, triisopropylate and tributylate, and diethyl aluminium ethylate are particularly mentioned. The mixture typically contains between 0-05 and 1% of the aluminium alcoholate, calculated as the metal and based on the weight of the polyethylene. Examples disclose mixing and grinding the aluminium alcoholate with polyethylene of specific gravity less than 0À95, drawing of the treated polymer into film and compression into sheets.

Title: Improvements in or relating to devices for regulating the elevational level of vehicle bodies
IPC: B60G17/052
Filed: 1959-12-29
Abstract: 921,371. Maintaining vehicles' heights constant. GANZ VAGON-ES GEPGYAR. Dec. 29, 1959 [Dec. 29, 1958], No. 44144/59. Classes 103(6) and 108(2). A device for regulating the elevational level of a vehicle body with an air cushion suspension provided with inlet and outlet means for pressure air is characterized by the provision of a system of communicating vessels 1, 2 to feel displacements of the body with respect to its running gear, the vessels containing a fluid medium and comprising a diaphragm 4 operatively connected to the inlet and outlet means. Two vessels 2, Fig. 1, are mounted on the bogie and connected by a flexible pipe 3 to a vessel 1 mounted on the frame and provided with the diaphragm 4 attached to a rod 5. When the vehicle frame sinks the pressure of liquid beneath the diaphragm raises the rod 3 to close a switch 8 and open a valve 10 to permit air to flow from the brake tank into the suspension of the vehicle to restore the frame to its original height. If the frame rises a switch 9 opens a valve 11 between the suspension and atmosphere. An adjustable clamp 12 and vents in the vessels 2 prevent the system from responding to vibrations and changes in barometric pressure. In Fig. 2, a liquid of high specific gravity, such as mercury, is used in containers 14, 20 and one of low specific gravity, such as brake oil in the upper part of the container 20, and in an adjustably-constricted pipe 21 and a container 13 having a diaphragm 16 attached to a rod 17. When the frame sinks, the rod 17 rocks a lever 22 to first close a valve 23 and then open a valve 24 to admit pressurised air to a piston 31. The latter closes a valve 25 and then opens a valve 26 to allow air to flow into the suspension until the frame is restored to its original height, the valve 23 allowing the air above the piston 31 to escape after the valve 24 has been reclosed by downward movement of the rod 17. If the frame rises a similar valve arrangement 27 . . . 30 causes the suspension to be vented to the atmosphere. In a third embodiment, two vessels connected by an adjustably-constricted pipe are mounted on the vehicle frame and the pressure of the liquid in one of the vessels is varied in dependence on vehicle height by a link connected to the bogie and acting upon the liquid through a lever, a spring and a diaphragm. A spring-loaded diaphragm in the second vessel operates one of a pair of valves for inflating and deflating the suspension.

Abstract: 1,045,407. Photo-electric direction finders. ALBISWERK ZURICH A.G. Nov. 18, 1963 [Nov. 19, 1962], No. 45371/63. Heading H4D. [Also in Division G4] Relates to apparatus comprising a lens system 1, 6, Fig. 1 (not shown), and photoelectric (p.e.) detector 7, there being a rotating disc 3 of alternate opaque and transparent sectors with its centre 5 off the optical axis 4, the infra-red radiation from a source 2 giving rise to a pulse-width modulation in the detector output, the phase of which is a measure of the relative angular position of the source image and the frequency of which is a measure of the radial distance of the source image from the centre of the disc. In a prior art disc the arcuate widths (in radians) of opaque and transparent sectors vary sinusoidally in the circumferential direction # and are proportional to distance r from the disc centre in the radial direction, Fig. 2 (not shown). In the processing of the p.e. detector signal there is afforded an A.C. voltage of amplitude proportional to r and phase proportional to #, Fig. 3 (not shown). According to the present invention the arcuate width of the transparent or opaque sectors in the radial direction is inversely proportional to r, Fig. 5 (not shown). It is stated that improved signal-to-noise ratio arises for sources near the optical axis. The amplitude of the A.C. voltage from the processing circuit is then proportional to 1/r and in order to provide a voltage proportional to r the arrangement of Fig. 4 (not shown) is employed: the input signal is rectified in unit 30, the output thereof is differentiated in unit 34, and the output of the latter controls the negative feedback factor of an amplifier 29; the output of amplifier 31 is thus proportional to r. The invention may be used in selfguided missiles. Phase reference may be afforded by a separate optical-electrical channel.
