The present Specification is similar to the parent Specification, but the claims deal with an interference rejecting device for use when deriving an equivalent narrow beam signal from two signals corresponding to broad beam reception patterns. As described, a signal corresponding to a figure eight directional pattern is applied to one end of a midpoint grounded potentiometer 72, and to the input of an inverter 50. Output from the said inverter is applied to the other end of the potentiometer. A second signal corresponding to a cardioid directional pattern is applied to one input of a summer 71, the other input of which is connected to the slider of the potentiometer 72. This enables inphase or anti-phase amounts of the firstmentioned signal to be combined with the second-mentioned signal and it is stated that the output signal from the summer 71 corresponds to a rotated cardioid directional pattern. The first-mentioned signal may be applied to the input of a paraphase amplifier, whose outputs are applied through cathode-follower amplifiers to the ends of the potentiometer (Fig. 12, not shown).

Title: Process and apparatus for recovery of solid thermoplastic polymers from solution
IPC: C08F6/12
Filed: 1965-10-01
Abstract: Normally solid thermoplastic polymers are recovered from solutions thereof by a process which comprises flashing a major proportion of the solvent at a temperature below the melting point of the polymer while simultaneously comminuting precipitated polymer, and thereafter agitating comminuted polymer at a temperature above its melting point to volatilize additional solvent, and recovering substantially solvent-free polymer.  The polymer may be initially comminuted in a primary comminution zone within the flash zone, and the thus comminuted polymer furthercomminuted in a secondary comminution zone to reduce the particles to a predetermined size.  Specified polymers are polymers of butadiene, ethylene, propylene, isobutylene and styrene.  Specified solvents are aliphatic and aromatic hydrocarbons, halogenated hydrocarbons and carbon disulphide. Apparatus suitable for carrying out the process of the invention is described and illustrated. Preferred solutions are those obtained by polymerizing ethylene in a hydrocarbon solvent such as cyclohexane or 2,2,4-trimethylpentane in the presence of a catalyst comprising chromium oxide associated with one or more of silica, alumina, zirconia and thoria.  The polymers may be made into pipes, electrical insulation and wrapping materials. Examples describe the application of the process of the invention to solutions prepared by polymerizing ethylene in cyclohexane in the presence of a chromium oxide/silica/alumina catalyst.

Abstract: 1,081,470. Acoustic measurement of physical properties. F. E. G. BOURQUARD. Oct. 5, 1965 [Oct. 7, 1964], No. 42214/65. Heading H4D. In apparatus for determining a physical property of a gaseous, liquid or solid sample from the velocity of sound waves in the sample, the sample acts as an acoustic resonator and is acoustically coupled to acoustic wave transmitting and receiving devices, at least one of which includes a further resonator. In the Fig. 2 embodiment for determining the temperature, moisture content, purity or composition of a fluid sample, a "measurement resonator" M is formed by tube 1 with end plates 2, 3, a " transmitter resonator " E is formed by tube 8 with end plate 10 and slidable piston 11, and a "receiver resonator " R is formed by tube 17 with end plate 19 and slidable piston 20. Resonators R and M are coupled by a rigid tube 27 and flexible tube 28, while resonators E and M are coupled by three rigid tubes 25 and flexible tubes 26. The fluid sample is introduced into the resonators E, R and M through apertures 49, 50 and tubes 25, 26, 27, 28. A loud-speaker 14 or piezoelectric transducer is energized by a variable-frequency oscillator 38 to set up standing waves in resonator M, the three resonators E, M, R being tuned by screw adjustment of the axial positions of piston 11, end plate 3, and piston 20 in tubes 8, 1 and 17 respectively. The positions of the nodes and antinodes of the standing waves, and hence the velocity of sound, are determined by screw adjustment of the axial position of a piston 31 within a tube 5 such that the standing wave pressure pattern in resonator M is scanned by tube 27, variations in the amplified output of a microphone 7 or piezoelectric transducer being observed on a meter 41, and the frequency of the acoustic signal being determined using an oscilloscope 45 or from the setting of oscillator 38. The acoustic coupling between resonators E, R and M may be adjusted by varying the length of tubes 25 and 27 which project into the resonators, and the end portions of tubes 25 and 27 may be flared or apertured (Figs. 3 and 3a, not shown), The resonators E, R and M may be arranged in a controlled-temperature enclosure. In an alternative embodiment (Figs. 5 and 6, not shown) for examining a solid material, each of the resonators E, R and M comprises a cylindrical block of the material. The resonators E and M are acoustically coupled by three metal needles (55) seated in bores (56, 57) in the ends of resonators E and M and centred within the bores by resilient sleeves (58). Resonators R and M are acoustically coupled by a single metal needle (59), one end of which is seated in a bore in resonator R and the other end of which engages, and may be traversed along, the circumference of resonator M.
