Title: Improvements relating to the control of the charging of electric batteries
Inventor: CHILTON ALFRED HENRY
IPC: H02J7/16
Filed: 1953-01-15
Abstract: 737,008. Systems of changing batteries. STONE & CO. (DEPTFORD), Ltd., J. Jan. 6, 1954 [Jan. 15, 1953], No. 1262/53. Drawings to Specification. Class 38 (4). The charging of a battery by a regulated generator is controlled by a pressure-responsive device sensitive to the rate of gas evolution in the battery which, through a pilot device governing the operation of an electromagnetic regulator, or the like, influences the regulation of the generator in such a manner that charging current is reduced in response to attainment of a predetermined rate of gassing. The pilot device may be a carbon pile resistance acted upon by the pressure-responsive device and shunting a portion of the usual swamp resistor in series with the operating coil of a carbon pile regulator controlling the shunt field excitation of the generator. Alternatively, the pilot device may be a switch operated by the pressureresponsive device and acting directly, or through an intermediate relay, to cut out resistance in series with the operating coil of a voltage regulator. Holding means may be provided for maintaining the pilot device in its operated condition when the rate of gassing subsequently falls.

[Class 40 (v)] A radio beacon providing an equisignal path Vg, Wh of desired angular spread in a vertical plane and extending symmetrically all round a vertical axis comprises two independently excited and modulated dipoles AOB, CSD mounted in the axis one above the other and each surrounded by a respective system of annular reflectors ac, ab and df, d'e formed as surfaces of revolution about the axis, the reflectors projecting the radiations through respective conjugate focal rings passing through points P, T respectively, and having their centres on the axis. The two beams overlap after passing through their respective foci, and in the system shown are reflected by an inverted conical diverger reflector Kl so that the overlapping portions between the lines Vg and Wh provide an equisignal approach path of the desired inclination around the vertical axis of the system. The reflectors ab and df, respectively below and above the equatorial planes of the dipoles AOB and CSD, are of elliptical section in order to bring the radiation reflected by them to the corresponding focal rings, and the reflectors ac and d<1>e are of partcircular section to reflect radiation falling on them back through the centre-points of the dipoles on to the elliptical reflectors. A system employing a third dipole and a similar reflector system beneath the others is described, the beam from which is reflected from a concavelycurved lower portion of the diverger reflector Kl to provide a narrow-angle landing beam of small inclination having a characteristic modulation. The whole system, including the diverger reflector Kl may be below the ground level E and covered by a transparent coverplate so as to give a clear runway over the system. Systems providing more than one equi-signal path and systems employing four dipoles, are also referred to.

Title: Improvements relating to the manufacture of condensation products of aldehydes and ketones
IPC: C08G6/02
Filed: 1932-01-19
Abstract: Condensation products of aldehydes and water-soluble ketones are manufactured by preparing a homogeneous mixture of the ketone with alkali and water by well stirring the ketone and water while gradually adding alkali, cooling the mixture while adding the aldehyde, immediately neutralizing the reaction mixture to prevent formation of resins, and finally isolating the condensation product. Preferably an excess of ketone is used and the addition of the aldehyde takes place below the surface of the well-stirred aqueous ketone-alkali mixture.  An example describes the preparation of hydracetylacetone by adding acetaldehyde to a mixture of acetone, water and caustic soda below 20 DEG  C., neutralizing, distilling off excess acetone and aldehyde and then distilling the hydracetylacetone under reduced pressure.

Title: Control circuits for polyphase motors
IPC: H02P23/24
Filed: 1978-01-17
Abstract: To have better control of the short circuit problem occurring in connection with the reversal of direction of rotation of controllable three-phase asynchronous motors, and thus to be able to change the direction of rotation without prior decrease in the speed of rotation, the reversal circuit (30) is associated with a blocking device (43) which allows reversal only after the inverter switching elements arranged in series have been extinguished. In addition, the frequency of the frequency generator (9) is kept proportional to the regulated direct voltage (U1). There is no destruction of the switching elements since the reversal process in each case virtually coincides with an extinction process. <IMAGE>
