Abstract: 1,168,122. Measuring temperature electrically. TEIJIN Ltd. April 26, 1967, No. 19177/67. Heading G1N. [Also in Division G3] Apparatus for controlling the temperature of a rotatable roller having heater means disposed between the shaft and the inner surface of the roller, comprises a temperature detecting device secured to the roller varying the frequency of a signal dependent on roller temperature, and means for transmitting the signal to a control arrangement without mechanical contact between rotating parts. The roller 1 has induction heating coils 7 and a temperature detector 10 such as a thermistor, a ferrite core, quartz resonator, or barium titanate electrostatic capacitor connected into a variable frequency oscillator circuit 13 the output from which is supplied to a rotating output member 21' which is electrostatically coupled to a collector member 22' connected to a frequency discriminator or amplifier 27 controlling the heating current. The oscillator is powered through a transformer 16, 17 having a rotatable secondary winding 16. Detector 10 may be any element which is changed in frequency, resistance, dielectric constant, magnetic permeability, or other property which changes with temperature. As an alternative to the transformer 16, 17 the oscillator power may be derived from a photo-electric cell arrangement supplied with light, or through a capacitive coupling.

Title: Improvements in and relating to electric drives for paper machines and the like
IPC: H02P5/50
Filed: 1921-07-21
Abstract: 186,470. British Thomson - Houston Co., Ltd., (General Electric Co.). July 21, 1921. Speed-maintaining systems. - A number of electric motors, such as are employed for driving paper-making machinery, are kept running at a standard speed by providing the field winding 15 of each motor 3 with a rheostat 16 operated by a reversible auxiliary motor 45 arranged to be brought into action by a device constructed like a small synchronous machine with a rotating armature 20 and an angularly movable field frame 21. The armature 20 is constantly driven by the motor 3 through adjustable speed gear, and is excited by direct current from an independent source. The field 21 has a polyphase or singlephase winding fed from a constant-speed altertor 33. When the speed of rotation of the armature 20 departs from synchronous relationship to the frequency of the current traversing the field 21, a torque is set up which deflects the field frame to one side or the other against centralizing-springs 35, 36, and thus connects up the motor 45 so as to operate the rheostat 16 in the appropriate direction for altering the field until the standard speed is restored. The working motors may be fed in common from a generator 6, which may be controlled on the Ward Leonard principle. The speed of the whole system may be changed by changing the speed of the alternator 33.

In the Specification said deviations #h and #s are referred to generally as "linear" deviations to distinguish them from the corresponding angular deviations. The azimuth and elevation beacons may comprise conventional ILS localizer and glide slope beacons or the azimuth beacon may comprise a Tacan beacon or a path-difference beatfrequency phase comparison system such as SETAC (see article referred to), the elevation beacon comprising a commutated aerial Doppler system. The function generators 20, 24 may be arranged to give practically all desired trajectories. Fig. 5 illustrates various functions which may be generated in cases a to e. The top figure of each case illustrates the required trajectory in elevation (height h versus distance R e ) The middle figure illustrates the variation of aircraft attitude angle γ F  (see Fig. 4) and aircraft elevation γ L . By switching over from one function to another at particular distances the flight path may be build up from a combination of cases a to e. Fig. 6, not shown, gives circuit details of a suitable function generator. Figs. 7, and 8, not shown, illustrate a function generator coupled to a unit (64) or (72) for smoothing the transition from one function to another. Fig. 11 illustrates a landing path in plan in which it can be seen there are portions which do not lie along radials of the localizer. Fig. 14 illustrates a glide path in elevation for a VTOL aircraft having portions not aligned with radials of the glide path transmitter. Figs. 12, 13 and 15 to 24 (not shown) show further examples of flight paths obtainable with the function generators.

Title: Carrier for semiconductor devices
Inventor: BARNES JAMES W
IPC: H05K7/12
Filed: 1970-04-27
Abstract: 1301121 Semi-conductor devices BARNES CORP 27 April 1970 20137/70 Heading H1K [Also in Division H2] Figs. 1, 4 and 6 show perspective, underside, and side-sectional views respectively of one embodiment of an indexed carrier 12 for carrying any encapsulated semi-conductor device 86 of the external form shown, the base section of the carrier being a type commonly used with flat-pack integrated circuits. Here, the carrier is provided with a stand-off post 42 around which are disposed holes extending through the base of the carrier to receive the leads of the device. The upper ends of the holes are provided with guiding flares defined by walls 38 extending radially from the post 42 to meet an annular wall 40. The form of the flares is varied between embodiments by suitably shaping the faces of both radial and annular walls. In a variant the upper edge of the radial walls 38 rises from the top edge of the annular wall to a higher point on the post 42 to further ease the insertion of the device into the carrier. An outer annular wall (not shown) concentric with the annular wall 40 may be of a height sufficient to encircle the base of the device encapsulation and to thus shield the leads 88 from accidental contact with external objects. The device is retained in the carrier by providing one or more (e.g. alternate ones) of the holes with a portion 34 of a reduced cross-section comparable to or slightly less in diameter than the undistorted lead to provide frictional engagement. The pillar 42 is continued at the underside of the carrier in a portion of constant and larger cross-section and the holes are flared away from the pillar to form guided entries for the flexible conductors 82 of a contactor assembly 54 on which the carrier may be retained by spring biased latches 64, 66. The conductors 82 are retained in the generally circular bore of the contactor body by solid 74 and apertured parts 76 with projecting parts 86 engaging axial grooves 80 of semicircular crosssection in the walls of the bore 78 to lock the contact assembly against rotation. Further bores 90, 92 are provided in the contactor body to enable it to be secured to a suitable mounting.
