Title: Improvements in and relating to Electric Motor Control and Apparatus therefor.
IPC: H02P25/26
Filed: 1917-02-03
Abstract: 108,430. British Thomson-Houston Co., and Hastings, H. C. Feb. 3, 1917. Master control systems.-In an electric motor control system with contactors operating in succession and with electro-magnetic auxiliary switches the magnetic force in which varies with the speed or back electromotive force of the motor, each auxiliary switch is mechanically interlocked with one contactor and controls the closing of the next contactor. The stator S of an induction motor is connected to the mains L<1>, L<2>, L' by a contactor 1 and resistances are cut out of the circuit of the rotor R by contactors 2, 3, 4, 5. The contactors have operating-coils C<1> - - C<5> and the first four contactors are interlocked with auxiliary. switches S<1> - - S<4>, the switches being held open when the contactors are open. The switches have windings A<1> - - A<4> connected across the slip rings K<1>, K<2> of the rotor which are set to drop their cores at different voltages. When the controller M is moved to its first position, the contactor 1 is closed and the motor starts. The auxiliary switch S<1> is released by the contactor but is held up until the current in the coil A<1> drops to a suitable value. The switch S<1> then drops and, on the controller being moved to the second position, the contactor 2 is closed. Contactors 3, 4, 5 are closed similarly. The controller may be moved to the full ' on ' position and the contactors will then close automatically. An ohmic resistance is connected in series with each auxiliary switch winding so that its current is practically independent of the frequency of the rotor currents. In an arrangement for use with direct-current motors, the windings of the auxiliary switches are connected across the motor armature and the switches are closed by the lifting of the cores as the back electromotive force rises.

Title: Improvements in or relating to diaphragm pumps
IPC: F02M1/00
Filed: 1970-01-14
Abstract: 1,273,845. Diaphragm pumps. SOC: ANON POUR L'EQUIPMENT ELECTRIQUE DES VEHICULES SEV MARCHAL. Jan. 14, 1970 [Jan. 15, 1969], No.1786/70. Heading F1A. In a diaphragm pump comprising a pumping diaphragm 12 and suction and delivery chambers 14 and 19, the delivery volume and pressure is regulated by an orifice 18 between the chambers which is controlled by a diaphragm 25. Liquid is passed from the suction chamber 14 to the delivery chamber 19, through valves 15 and 20, on reciprocation of the diaphragm 12 by lever 4 and spring 9, and thence to the outlet pipe 33 via valve 23. Diaphragm 25 is pressed by a spring 27 against the orifice 18, such that at an excess delivery pressure the diaphragm is displaced and allows fuel to be spilled back into the chamber 14; vapourization of liquid in the delivery chamber or spout has a similar effect. Increase in pressure in the suction chamber due to vapourization therein is overcome by using a diaphragm spring 9 which will be unaffected by the pressure increase. In another embodiment Fig. 2 (not shown) valve 23 is replaced by a ball valve and the orifice is controlled by a peg carried by a spring-loaded control diaphragm; one arm of a two armed pivotally mounted lever, whose other arm is connected to the control diaphragm, acts to close the ball-valve when the recycle orifice is opened.

Title: Improvements in and relating to the manufacture of quartz resonators
IPC: H03H3/04
Filed: 1945-01-26
Abstract: 585,114. Etching. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 26, 1945, No. 2070. Convention date, Jan. 28, 1944. [Class 100 (ii)] [Also in Group XL] Shaped articles such as resonators of crystalline quartz have their dimensions reduced by being subjected to the dissolving action of an aqueous solution of hydrofluoric acid to which is added ammonium bifluoride to produce uniformity of dissolving action. Resonator elements of quartz are fabricated by first cutting and rough grinding to approximately the desired frequency and then chemical reduction of thickness permits further approximation to the desired frequency by unskilled labour with greater speed. The final accurate adjustment is then carried out by hand. Abrasive material from the grinding operation, embedded in the surface of the quartz blanks is removed before the timed acid treatment by an etching reagent, and grease is removed by acetone. The clean crystals are subjected for a predetermined period, at room temperature, to the etching bath comprising an aqueous solution of hydrofluoric acid and ammonium bifluoride and have a smooth polished surface after treatment. The etching rate of a reagent may be .determined by observing the change in frequency of a chosen oscillator crystal after a known period of immersion and the time required to effect a given change of frequency can be estimated. The duration of the treating time depends on the grade of crystal, temperature of the reagent, amount of material to be removed and the concentration of the reagent. The latter is restored as the reaction proceeds by the addition of anhydrous hydrofluoric acid. Crystal blanks are held in chemically inert supports and relative motion between the reagent and the crystal is produced in order to preserve contact between the crystal surface and the solution by the removal of gas bubbles. When the etching is complete all traces of the reagent are removed from the crystal to maintain its liveliness of oscillation by first rinsing with distilled water, then with a dilute solution of ammonium hydroxide, then again with water and finally with acetone.
