Title: The manufacture of alkyloxyacridines
IPC: C07D219/06
Filed: 1923-05-02
Abstract: Alkyloxyacridines are prepared by alkylating the corresponding oxyacridines in the presence of acid-binding substances, the acridine nitrogen not being alkylated in the process.  From dioxyacridines may be obtained both mono- and dialkyl derivatives.  The products are of therapeutic value, arresting the growth, for instance, of diphtheria bacilli and streptococci. According to examples 3 : 6-dioxyacridine is methylated or ethylated with dimethyl or diethyl sulphate, 2 : 7-dimethyl-3 : 6-dioxyacridine is methylated with p-toluenesulphonic methylester, and 3 : 6-dioxy acridine is oxyethylated with ethylenechlorhydrin with or without pressure; in each case the alkylation is performed in presence of caustic soda.  The properties of the mono- and di-methyl- or ethyl-ethers and of the bis-oxyethylether are given.

Title: Improvements in and relating to control means in alternating current servo motor systems
Inventor: BELSEY FREDERICK HAROLD
IPC: G05D3/14
Filed: 1950-05-15
Abstract: 696,895. Control of A.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 9, 1951 [May 15, 1950], No. 12077/50. Class 38 (iii) Relates to a servo system in which the windings of an induction motor are connected to provide reference and control phase circuits, the reference phase circuit being energized with current of the normal operating value only during such times as the motor is required to produce maximum torque. As shown, the control phase winding 2 of an induction motor 1, is connected to the output stage of a magnetic amplifier of the type described in Specification 685,320, [Group XXXIX], the input to the amplifier including means according to Specification 678,385, [Group XXXVIII], for example. A reference phase winding 3 of the motor 1 is energized from an auto-transformer T1 in quadrature with the winding 2, the current in the winding 3 being controlled by a transductor comprising a pair of cores A, B, or the equivalent. The output windings 4, 5, of the transductor are provided with a positive feed-back effect by means of rectifiers 6, 7. The cores A, B, have biasing windings 8, 9, and a control winding 11 connected to a rectifier 12 in series with the control phase winding 2 of the motor. In the absence of current in the control winding 11 the output current of the transductor will be zero or some value less than the normal operating value required in the winding 3. When current flows in the winding 11, however, the current in the winding 3 will be increased to the normal operating value. The mean heating of the servo motor is thus reduced in applications involving rest periods. The transductor arrangement controlling the reference phase current may comprise a plurality of stages, the amplifying stages prior to the final stage being preferably of the push-bell type. Additional biasing windings 15, 16, are adapted to be energized when either of the limit switches 13, 14, are closed so as to reduce the current in the winding 3 during stalled conditions of the motor. Alternatively, the limit switches may be arranged to modify the current in the windings 8, 9. Reference has been directed by the Comptroller to Specification 617,704.
