Title: Proximity monitoring
Inventor: HILLS BARRY
IPC: F16P3/14
Filed: 2009-12-11
Abstract: Presented is a proximity monitoring apparatus and method. The apparatus comprises: a transmitter adapted to transmit a electromagnetic signal in a periodic time slot defined with reference to a master clock signal; and a detector adapted to receive the electromagnetic signal transmitted by the transmitter, to determine the period of the received electromagnetic signal, and to determine that the received electromagnetic signal was transmitted by the transmitter of the proximity monitoring apparatus if the determined period is within a predetermined range of values. The separation of the receiver and transmitter is according to a measure of the near-field of the received signal. The apparatus is suitable for use within the construction industry to so that a warning can be given to people about the presence of an oncoming vehicle. The warning could be triggered by the rate of change of separation between the vehicle and the person. The warning means could be a vibrator within the workman's helmet or hat.

Abstract: 331,816. Strong, H. W., and Imperial Chemical Industries, Ltd. April 2, 1929. Hydrogenation, destructive.-The vapour of higher boiling-point oils, such as middle oils, is passed together with hydrogen over a contact mass consisting of iron coated with zinc and then over a porous contact mass of ferric oxide or a chemical equivalent thereof i.e., a substance similar to that to which the ferric oxide would be converted under the working conditions; such a catalyst would be produced by heating ferric oxide in hydrogen at 500‹ C. The iron coated with zinc is preferably used in the form of gauze or wire, and the ferric oxide may contain small amounts of other substances .such as alumina. Separate vessels may be used for the two contact masses or they may be employed in the same vessel, the masses being arranged in juxta position or in alternate layers. The same temperatures and pressures may be employed, the preferred conditions being 20 atmospheres pressure or over and 400‹ C. or over. Where two vessels are used, different temperatures may be employed, e.g. the iron-zinc catalyst is maintained at 460‹ C. and the ferric oxide at 500‹ C. A middle oil obtained by the destructive hydrogenation of bituminous coal is passed in the vapour phase with hydrogen at 25 atmospheres over two contact mass arranged in series in the same high pressure vessel at 500‹ C., the zinciron catalyst being in the form of superposed layers of gauze and the ferric oxide being prepared as described in Specification 220,649, [Class 1 (i), Chemical processes &c.].

Abstract: 968,699. Producing slubbed polyolefine filaments. PHILLIPS PETROLEUM CO. March 21, 1961 [July 1, 1960], No. 10240/61. Drawings to Specification. Heading B5B. Knopped (slubbed) monofilaments are produced by melt-spinning polymeric 1-olefines under conditions of temperature and pressure which are respectively lower and higher than the minimum and maximum which can be used for the production of smooth cylindrical monofilaments and in such a manner that a relatively thick filament having a serrated configuration along its surface is formed, and thereafter drawing the filament, whereby knops are formed along the length thereof at sections of increased thickness. The temperature of the extrusion head may be maintained approximately 25‹ to 75‹ F. below that in the zone of the extruder remote from the extrusion head. The serrated monofilament may be drawn at a draw ratio of from 3: 1 to 10: 1. The spinneret orifice may be from 0.005 to 0.10 inch in diameter. The serrated monofilament may be cooled prior to being drawn. The polymeric material used may be a 1-olefine having from 2 to 8 carbon atoms in the molecule, a blend of a polyethylene and a polypropylene, or a blend of a polyethylene having a density of 0.94 to 0.98 and a polyethylene of lower density. The polymeric material may be a mixture of a copolymer of 95 to 99% of ethylene and 1 to 5% of 1-butene and polypropylene, the copolymer constituting 25 to 90% by weight of the mixture. The ratio of the length to the diameter of the extrusion orifice may be from 0.3: 1 to 3:1. In an example, a 60/40 polyethylene-polypropylene blend is extruded at an extrusion head temperature of 480‹ F. and a pressure of 2350 p.s.i.g. through a spinneret having orifices 0.017 inch in diameter to form " sawtooth " monofilaments which after cooling are drawn at a 4: 1 draw ratio to form knopped monofilaments, the filaments being thereby oriented without loss of knop.
