Title: Process for polymerizing 4-methylpentene-(1)
IPC: C08F210/00
Filed: 1960-07-04
Abstract: Poly-4-methylpentene-(1) is made by polymerizing a mixture of 4-methypentene-(1) and at least one other hexene in the presence of a catalyst comprising (1) a compound obtained from the reaction of a compound of a transition metal of Group IV, V, or VI, of the Mendel<\>aeeff Periodic Table with an organometal compound of a metal of Group II, or III of the Mendel<\>aeeff Periodic Table and (2) a halogencontaining organo-aluminium compound.  The polymerization may be effected in the presence of an inert hydrocarbon dispersing medium. Alternatively the isomeric hexenes may act as the dispersing medium.  Mixtures of the hexenes may be obtained by the dehydration of methylisobutylcarbinol with gamma-aluminium oxide at a temperature of from 220 DEG  to 300 DEG C., or by the dimerization of propylene, or the trimerization of ethylene.  Component (1) of the catalyst is preferably made by reacting TiCl4 with monoethyl-aluminium dichloride or diethyl-aluminium monochloride.  Component (2) of the catalyst is generally diethyl-aluminium monochloride.  The poly-4-methylpentene-(1) is mainly isotactic in structure and has a density within the range of from 0,82 to 0,86, an X-ray crystallinity of from 10 to 90% and a melting temperature of from 210 DEG  to 260 DEG C.

Title: Improvements in and relating to acoustic devices of the horn type
IPC: H04R1/30
Filed: 1932-08-22
Abstract: 404,072. Acoustic horns. BEALE, E. S. L., Green Doors, Stanwell Moor, near Staines, Middlesex. Aug. 22, 1932, No. 23515. [Class 13.] An acoustic horn for a sound reproducing instrument is filled with a gas or vapour in which the velocity of sound is less than in air, e.g. Difluor-dichloro-methane, Methyl Bromide, Isobutane or Butane and is associated with a diaphragm mounted so that the reactance of the stiffness impeding its motion has at the cut-off frequency of the horn with air filling, a value which is less than the resistive impedance of the horn with air filling in the range of frequencies over which the latter is substantially constant. The mouth of the horn is covered with a thin flexible diaphragm made of a material such as metal foil, cellulose or doped fabric or of a combination of metal foil coated with organic matter to close any perforations therein. In order to maintain the pressure within the horn substantially atmospheric, the diaphragm may be loosely arranged or a breather valve provided. Alternatively the horn may communicate with a flexible bag or a cylinder containing a movable piston. A steady stream of the gas or vapour may be fed to the horn, the small end of the horn preferably being arranged lower than the mouth so that any air which may enter collects at the latter. The horn mouth should preferably be rather larger than usual for a given rate of taper for the efficient radiation of the lower frequencies. The diaphragm of the sound reproducing instrument used with the horn is so supported that its natural frequency is below or does not greatly exceed the bass cut-off frequency of the horn.

Title: Improvements in or relating to means for regulating the terminal voltage of a generator
IPC: H02P9/26
Filed: 1925-09-23
Abstract: 264,891. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Sept. 23, 1925. Regulation, automatic.- The terminal voltage of a generator G is regulated according to the load current flowing through a resistance R1 by a hot cathode discharge device D connected in shunt to the exciting winding B2, a resistance R2 being in series with the circuit of the winding B2 and device D. The filament g of the device D is in circuit with a battery B1 and part of the resistance R1. If the current from the battery B1 opposes the current derived from the resistance R1, then as the load on the generator increases, the heating current of the filament decreases, whereupon the plate current decreases and the current in the winding B2 increases, thus the generator is either regulated for constant voltage or is overcompounded. If the battery current has the same direction as that derived from the resistance R, then the generator is undercompounded. A second device D<2> may similarly be used, and be heated according to the terminal voltage of the generator and thus regulates the terminal voltage as the speed of the machine varies. If the generator G is an alternator the current derived from the resistance R1 is rectified by a synchronous commutator. In a modified arrangement, the filament of the device D is heated by a constant current and the potential of a grid is varied according to the current in the resistance R1. The device D may also be connected in series with the exciting winding or be associated with an auxiliary winding.
