Title: Improvements relating to polyphase windings for dynamo-electric machines
IPC: H02K3/28
Filed: 1948-05-13
Abstract: 644,676. Winding layouts for dynamo electric machines. KREBS, E. W. May 13, 1948, No. 13091. [Class 35] The stator of a polyphase machine is wound so that the number of conductors per slot in each phase zone, where two phases overlap, increases steadily from the edge of the zone, the total number of conductors in each slot being the same. In the illustration shown, in which the centre of a symmetrical zone falls on a tooth, the number of phase conductors in the slots are in proportion to the angular distance of the slot from the zone edge, i.e. in the ratio of 10 : 30 : 50. Examples are also described in which the centre of the zone falls in a slot, the zone is not symmetrically disposed with respect to the slots, the pole pitch is not an integral number of slot pitches, and the windings have a reduced spread factor. Arrangements of the coil overhangs are described in which the coils may each have the same span of one pole pitch or groups of coils comprising parts of zones may be connected in concentric fashion. The winding may be simplified by placing both sides of each coil in the same slot position.

Title: Apparatus for sampling gas expired by a patient
Inventor: NUNN JOHN FRANCIS
IPC: G01N33/497
Filed: 1956-04-30
Abstract: A breathing-tube 1 through which the patient is intended to inspire and expire is connected to analyser 2 through which gas can be drawn from the tube 1, or from the patient's respiratory tract.  The analyser 2 incorporates a semi-permeable or other restrictive device whereby gas can only enter the analyser from the breathing-tube 1, or the patient's respiratory tract when a flow is induced by other means such as a suction pump or fan 4 actuated by a source of electric power 5.  Alternatively a pump or fan could be situated in the tube 3 between the analyser and the breathing-tube 1, or the respiratory tract.  Moreover, between the <PICT:0829409/III/1> analyser and the pump or fan is connected a valve 6 actuatable by a solenoid 7.  Two spaced points in the breathing-tube 1 are connected through a pair of tubes 8 and 9 respectively to opposite sides of a diaphragm 10 of a pressure-sensitive switch 11, and the arrangement is such that the pressure differential acting on opposite sides of the diaphragm as the patient expires through the tube 1 will cause the switch to close.  The switch 11 is in series with an adjustable resistance 12 and the coil of a relay 13 which is connected to a direct-current supply from the power source 5. Energization of the relay 13 closes the switch 14 and moves the contact piece of the switch 15 to the alternative position.  When the switch 11 is closed the condenser 16 is charged at a rate depending on the setting of the resistance 12 to provide a delay before actuation of the relay 13.  When the relay 13 is actuated the switch 15 is changed from the position shown to discharge the condenser quickly through the resistance 17, and at the same time the switch 14 is closed to energize the solenoid 7 and thereby open the valve 6.  Opening of the valve 6 will cause the suction pump or fan to be placed in operative connection with the analyser so that gas is drawn into the analyser from the breathing-tube, or from the patient's respiratory tract.  At the end of expiration the switch 11 opens and the parts return to the positions shown.  In use the resistance 12 is so adjusted that gas is only drawn into the analyser during the latter part of the expiration of the patient, normally corresponding to the expiration of the final part of the "end-tidal gas."

Title: Improvements in or relating to television receivers
IPC: H04N5/57
Filed: 1957-04-25
Abstract: 856,016. Television. TELEFUNKEN G.m.b.H. April 25, 1957 [April 25, 1956], No. 13195/57. Class 40(3). [Also in Group XL(c)] The gain of the video amplifier valve of a television receiver is varied by adjusting the potential of an electrode of a further valve connected in series with an electrode of the amplifier valve and consequent changes in picture brightness are compensated by applying a voltage derived from the anode circuit of the futher valve to an electrode of the cathode-ray tube. In Fig. 2 the gain of the video amplifier 1 of a television receiver is controlled by varying a potentiometer 15 so as to vary the impedance of a valve 12 connected in the screen grid circuit of the video amplifier valve 1. Variation of potentiometer 15 also varies the voltage across a potentiometer 16 so as to maintain the brightness constant as the contrast is adjusted. Synchronizing pulses developed across resistor 5 are applied to the cathode of a valve 6, the anode of which receives keying pulses so that a voltage is developed across a capacitor 8 for automatic gain control. The maximum amplitude of the video signal from valve 1 depends upon the screen potential of the valve so that varying the gain by varying the screen voltage also varies the level at which the valve limits interference.
