Title: Method of and apparatus for the automatic control of domestic water systems
IPC: F04D15/02
Filed: 1949-11-10
Abstract: 666,461. Water supplies. GARVENSWERKE MASCHINEN-PUMPEN- & WAAGENFABRIK. W GARVENS. Nov. 10, 1949. [Dec. 6, 1948] No. 28857/49. Class 68 (i). In a domestic water installation the driving motor of the delivery pump is switched on when a predetermined minimum pressure is reached at a given point in the system and is switched off when the output of the pump reaches a predetermined minimum as the pressure at the given point increases. The pressure drop at the given point from when the motor is switched off until it is switched on is approximately one metre of water head. The apparatus has a stand pipe 7 which projects above the highest supply point of the system and when the motor 1 is switched off this stand pipe has been filled. When a tap is opened the level in the stand pipe drops and when the pipe is empty the variation in pressure on the pressure switch 9 due to the loss of head in the stand pipe is sufficient to switch on the motor. To reduce the frequency of the switching operations the capacity of the stand pipe is increased by widening the cross-section of the pipe over the whole or part of its length or by forming at the upper end a vessel from which the admission or discharge of air is controlled by a ball float valve. A pressure container 8 with a ball float valve may replace the stand pipe the container being filled with water except for that space occupied by an air cushion.

Patent GB-152349-A (GB)
Title: An improved process for producing spun material resembling wool or cotton from viscose solutions
IPC: D01F2/08
Filed: 1919-11-13
Abstract: The incompletely-hydrated alkali cellulose to be converted into viscose, and subsequently into a spun material resembling wool or cotton, according to the parent Specification, is, in the case of well-opened cellulose, prepared simply by immersing the cellulose for a short time in caustic alkali lye, without any subsequent maturing, that is, the alkali cellulose immediately after pressing to remove excess lye, is treated with carbon disulphide; by this modification a more woolly and stronger spun material is obtained.  The cellulose is opened by thorough boiling, and the time of immersion in the soda lye is, in the case of a material in the form of flock, about ten minutes, and in the case of a matted material, two hours may be necessary.  The quality of the spun material is further improved by reducing the proportion of carbon disulphide, and by increasing the cellulose contents of the spinning solution.  The preparation of the alkali cellulose may be carried out at normal temperature; but during the subsequent stages a somewhat lower temperature should be maintained.  The viscose solution is spun in an unripened condition. Specification 1378/12 is referred to.

Title: Means for controlling the excitation of d.c. electric motors
IPC: H02P7/34
Filed: 1937-10-25
Abstract: 504,619. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., and CARNEGIE, H. S. Oct. 25, 1937, No. 29131. [Class 38 (iii)] [Also in Group XXXV] Field control.-A motor 1 is excited from two exciters 3, 4, the exciter 4 being independently driven and having a field winding 4a supplied through a regulator 5 from a source independent of motor load or speed, and the exciter 3 being driven by the motor and exciting it as a continuous function of both its speed and its armature current, the compounding or decompounding being greater at high speeds than at low speeds. The motor 1 which may drive a reversible rolling mill is fed from a Ward-Leonard generator 2 and has its field 1a supplied from the exciters 3, 4, which may be connected in series and also in series with a separate source T1, T2. The field 3a of the exciter 3 may be connected across an inductive shunt 11 which may be adjustable, and the exciter may compound the motor during motoring and decompound it during regenerative braking, acting in the correct sense irrespective of the direction of rotation. In a modification, Fig. 2, the field 3a is directly in series with the motor armature, and the exciter 4 has an additional field 4b fed from the exciter 3 through a resistance 7 shunted by a rectifier 8. The field 4b gives a decompounding effect during motoring and a compounding effect during braking, and its inductance causes its effect through the exciter 4 to lag behind the change in armature current. In this way the field 4b tends to compensate for the inductance of the field 1a. An inductance 6 may be provided to increase the compensation. The rectifier 8 is effective to give different degrees of compounding for motoring and braking. A similar result may be obtained by connecting an additional motor field in series with a rectifier across the exciter 3. A polarized relay may be substituted for the rectifier. In a further modification, a third field on the exciter 4 opposing the winding 4b and fed from the exciter 3 is effective to cancel the field 4b, but at a predetermined current varying with speed a regulator increases its effect to increase or introduce the compounding action. The third field may alternatively be connected across 'a Wheatstone bridge connected to the exciter 3, resistance in the bridge circuit being adjusted by a regulator to bring the third field into action at a predetermined current. The regulator coil may be connected in the motor armature circuit or across the exciter 3. A vibratory regulator may be employed and the exciter 3 may supply part of the field 1a or an independent winding. A series winding may be provided on the excite r 4.
