Abstract: 1,090,118. Control of D.C. motors. INSTITUTE ELECTROSVARKI IM. E. O. PATONA. Oct. 20, 1965 [July 24, 1964], No. 29789/64. Heading H2J. [Also in Division B3] In arc welding apparatus in which a D.C. motor 1 for feeding the electrode is connected to the welding circuit for energization thereby and the welding current is controlled by a contactor 12 closed by a start switch 5, welding is stopped by electrodynamic braking of the motor 1 and opening of the contactor 12 is delayed until after extinction of the arc. The welding circuit is prepared by closure of a switch 11. Operation of the start switch 5 energizes the winding of contactor 12. The motor 1 starts, the arc strikes and a shielding gas valve 9 is actuated. When the start button 5 is released the armature alone or the armature and shunt winding of the motor 1 is short-circuited to stop the motor 1 and the arc burns back until it extinguishes. The winding 2 is energized by discharge of a condenser 3 so that the contactor 12 does not release until after the arc extinguishes. This maintains the flow of shielding gas.

Title: Process for moulding non-plastic metallic oxides
IPC: C04B33/13
Filed: 1932-10-26
Abstract: A process for moulding non-plastic metallic oxides, e.g magnesium oxide, beryllium oxide, zirconium oxide, aluminium oxide, or mixtures thereof, consists in calcining the oxide to incipient crystallization, grinding to a size of grain of about 2-15 m , deflocculating by adding dilute acid, e.g. hydrochloric, as well as by stirring and heating, and then extracting moisture so that the mass is in a crumbly state.  The crumbly mass can be moulded by pressing, stamping or jigging.  In an example 6-8 parts of dilute hydrochloric acid are added to 100 parts of aluminium oxide which has been heated to about 1200-1300 DEG  C. and ground. The mass is heated to about 60 DEG  C. and stirred for a long time, preferably for several days.  A portion of the water is removed in filter presses and the crumbly mass is moulded and, after removal from the mould, sintered at a temperature above 1600 DEG  C., preferably at 1750 DEG C.  Moulds resistant to acids, such as moulds of tempered beryllium alloys, especially of copper-beryllium are used, and highly viscous oil may be added to the mass to facilitate removal of the formed articles from the moulds.

Title: Improvements in or relating to colour television systems
IPC: H04N9/72
Filed: 1956-10-04
Abstract: 842,146. Television. RADIO CORPORATION OF AMERICA. Oct. 4, 1956 [Oct. 19, 1955(2)], No. 30331/56. Class 40(3). In a colour television receiver the D.C. operating point of the component-colour channels is stabilized by means of a circuit, shown generally in Fig. I, in which pulses 15, recurrent during line retrace intervals, are applied to the grid cathode circuit of an electron discharge device, such as valve 15, to establish an operating bias point across condenser 9 determined by the amplitude of the pulses. The electron discharge device may be the amplifier which supplies colour-difference signals to one of the "guns" of a tri-colour picture tube (Fig. 4, not shown) or the valve which performs the function of synchronous detection in one of the colour channels (Fig. 6, not shown) a similar circuit being included in each of the other two colour channels. The electron discharge device may also comprise the grid-cathode circuit of the picture tube itself, the connections to the transformer 7 in this case being modified so that negatively going pulses 15 are available for application to the (parallel connected) cathodes of the tube gun (Fig. 8, not shown). In the case of the first two arrangements referred to above the bias operating point of each colour channel may be varied by varying the pulse amplitude by means of potentiometer 17 which thus affords differential background control and hence control of the colour balance of the reproduced picture. A further control potentiometer for varying the amplitude of the pulses before they are supplied to the individual potentiometers 17 or before application to the circuit employed in the embodiment of Fig. 8 (not shown) allows control of the overall background brightness. In each embodiment the operation of the circuit is enhanced and rendered independent of voltage drop in the interface resistance of the cathode of the electron discharge device by supplying to a further electrode therein (e.g. the anode) pulses of suitable amplitude and of opposite polarity to the pulses supplied to the control grid.

Title: Improvements in or relating to instruments for indicating the rate of ascent and descent of aircraft
IPC: G01C9/00
Filed: 1929-10-07
Abstract: 341,076. Indicating rate of ascent and descent of aircraft. WENK, F. R., Villa Caecilie, Lindenberg, Kreis Beeskow, Germany. Oct. 7, 1929, No. 30377. [Classes 106 (ii) and 106 (iii).] An instrument for indicating the rate of ascent and descent of aircraft comprises a pressure gauge of the statoscope type arranged to indicate variations in a fluid-pressure compounded of static pressure due to height and dynamic pressure due to the air speed. An aperture in an airtight casing 1 is closed by a diaphragm 2 covered with a smaller casing 3 the interior of which communicates with the casing 1 by several capillary tubes 4. A rod 5 -transmits movements of the diaphragm to a pointer. 6 moving over a scale 7. The casing 3 is connected by a pipe 9 with a Pilot-tube device formed by a stream-lined body 10 with an inner metal lining 11. The body is open at its forward end and extending through the wall at right angles is a tube 12 cut off obliquely at the inner end as shown. A drain orifice 13 for rain is provided and the lining is surrounded by a heating spiral 14 to melt off ice. When the aircraft is flying steadily in the horizontal direction, the pressure in the pipe 9 is uniform and the pointer 6 reads zero. When the aircraft deviates from the horizontal, the pressure rises or falls and the pointer moves according to the difference of pressure between that of the pipe 9 and chamber 1 thus indicating rate of rise and fall. The capillaries 4 enable the balance to be restored. The inertia of the mass 8 clamped to the rod 5 tends to accentuate the indication. The indications given are in fact not by the pointer shown but by a tiltable mirror reflecting a spot of light on to a screen. The instrument is combined on the same 'board with two air-speed gauges connected to Venturi or Pilot-tube static heads to the left and right. These indicate with pointer 15, 16, Fig. 2, on scales 17, 18, the statoscope instrument indicating between them by a pointer 61 moving over a scale 7<1>. If--the pointer 6<1> nears the other pointers, a position of unsafe stability is indicated. In another arrangement the indicating mechanism is similarly arranged between the pointers of a gyroscopic instrument for indicating the lateral inclination of the aircraft. In a third form the illuminated pointer from the instrument of the invention is also acted upon by a gyroscopic device to indicate lateral inclination.
