Abstract: 628,961. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. March 22, 1946, No. 8930. Convention date, April 23, 1945. Drawings to Specification. [Class 40 (vii)] In order to compensate for the increase in sensitivity of a receiver to deviations from the course-line defined by a radio beacon of the double tone overlapping beam type as the beacon is approached, an additional signal is radiated on a slightly different frequency within the receiver pass-band and is directed. so as to be received only in the vicinity of the beacon where the reduction in sensitivity is desired. In the region where the auxiliary signal is received the total carrier level is increased so that the automatic volume control circuits of the receiver are operated to reduce its overall sensitivity. The invention is especially applicable to beacons providing a glide path for aircraft, such as, for example, a beacon of the type described in Specification 546,668, wherein the aircraft is maintained on a course off-set from the beacon so that the auxiliary signal may be radiated from the beacon and directed across the course-line.

Title: Process for the production of polymeric materials
Inventor: AMOS JAMES LAWRENCE
IPC: C08F6/10
Filed: 1960-03-15
Abstract: In the production of polymeric material by partial polymerization of monomers or monomer mixtures which contain at least one heat-sensitive monomer such as acrylonitrile, with subsequent removal of the unpolymerized monomer or monomers by devolatilization, the devolatilization is carried out in two steps, the first step at a relatively low temperature such as 120 DEG -190 DEG C. in a devolatilizer, the temperature of whose surfaces is kept below the decomposition temperature of the monomer vapours, and the second step at a substantially higher temperature, such as 210 DEG -260 DEG C. under a pressure which is substantially lower than atmospheric pressure, such as a pressure below 150 mm. Hg.  The process is particularly applicable to the copolymerization of styrene or alphamethyl styrene and acrylonitrile in the presence of an aromatic solvent such as diethylbenzene, the polymerization being stopped at 40%-70% conversion.
