Abstract: 720,590. Glass fibres. RIEDEL, J. C. Sept. 1, 1953 [Sept. 5, 1952], No. 24134/53. Class 56. The ends of glass rods 11 from which filaments are spun are heated by means located in recesses 2 away from the spinning operation, the heat being, at least partially, intercepted by screening. A screening member 6 of ceramic material is inserted into a refractory block 1 and rests on asbestos or like plates 9.

Title: Electric waveform generators
IPC: H03K4/06
Filed: 1975-06-04
Abstract: 1509385 Transistor triangular or trapezoidal waveform generators MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 June 1975 [4 June 1974] 24175/75 Heading H3T A waveform generator comprises a differential amplifier consisting of a pair of transistors 39, 41 having their collector currents made equal or proportional by means of a current mirror 43, transistors 39, 41 being arranged to be conductive alternately under control of transistors 48, 49 so that on alternate half cycles, capacitor 53 charges via the current mirror 43 and discharges with the same constant current through transistor 41. As described, during positive half cycles of square wave at 47 transistors 48 and 52 are conductive so that 49 is off, allowing the base of transistor 41 to be controlled by the voltage at the emitter of transistor 36. This enables capacitor 53 to discharge via transistor 41. During negative half cycles at 47, the reverse conditions apply so that capacitor 53 charges via the current mirror 43. If the periods of the square wave at 47 are made sufficiently long, a trapezoidal wave is provided across capacitor 53 whiich is coupled via emitter follower 54 to output terminal 56. The slope of either ramp may be controlled by a signal at 59 which turns on transistor 56 and thus shunts capacitor 53 by further capacitor 57. A mathematical treatment is included.

Title: Methods and apparatus for recording well logging measurements
IPC: E21B47/12
Filed: 1971-04-19
Abstract: 1357151 Displaying and recording well logging data SCHLUMBERGER INLAND SERVICES Inc 19 April 1971 [2 March 1970] 24203/71 Heading G4H Apparatus for recording or displaying well logging signals as a function of depth comprises a digital sweep circuit for sweeping energy in a line across a medium, energy level control responsive to the well logging and other signals and means for generating relative movement between the medium and energy sweep in a direction perpendicular to the sweep. The energy is preferably a cathode-ray tube beam with a film moving across a fibre optic screen, and may also be an electrostatic device. The data may be stored in a digital tape recorder 21 in n channels of series data or may be received direct from the logging device. Depth information is either recorded or received direct from a displacement encoder engaging the logging device suspension cable. The data signals from 21 are low-pass filtered at 22 and pass to modulators 23. The modulated signals are passed to coding circuits 45 and also to area coding card reader 47. The line and area coding signals are combined in circuit 42 and used, along with other signals to modulate the brightness control of CRT 25. A film 36 moved by constant speed motor 37 records the CRT display. Sweep and scale line circuit.-The beam scanning and general synchronization is controlled from sweep circuit 24. The sweep voltage is generated by a digital to analogue converter connected to the output of a clock fed counter. The counter is reset on reaching a predetermined reading. Scale lines are generated by the response of a comparator to predetermined counts. Depth circuits.-The depth is signalled every 10 feet and a pulse occurs every ¢ft. The initial depth of recording is set on switches 61 (measurements are made upwards so depth decreases) and the determination circuits 60 generate a signal every 100 feet which is displayed on CRT 67 for recording on the film 36. Depth interval generator supplies signals at 2 feet intervals to circuit 42 for producing depth lines on the recording, the lines at 10 and 50 feet being thicker. Pulse position and width modulators.-These allow for rate of change of signal, a signal during a high rate of change being generated as lines on the CRT screen so that the trace does not appear discontinuous. The input signal and a delayed signal are compared with the sweep waveform and the time difference between equality is used to determine the length of the output signal. Line coding circuits.-These operate under instructions from card reader 46 to produce the information trace on the recording medium as a dotted, dashed, long dashed or solid line. Area coding.-The area coding card reader selects signal channels and patterns which indicate particular strata. The patterns are generated in the area between the channel traces when the traces have predetermined relationships. To maintain a constant recording level, the tube brightness is controlled by monitoring a portion of the trace which should have constant intensity.

Filed: 1975-06-05
Abstract: 1515351 Processing physiological signals SIEMENS AG 5 June 1975 [21 June 1974] 24333/75 Heading G1N(E) In an input circuit arrangement for an E.C.G. or an E.E.G. circuit, disturbance signals due to outside electro-magnetic influences or a disconnected electrode(s), are eliminated by supplying the signal from each electrode R, L or F to an input operational amplifier 1, 2 or 3 which also receives a signal from a common potential point 5 derived from one of the electrodes R and representative of the disturbance (hum) signal. The arrangement of resistors R 1 , R 2  on the amplifiers 1, 2, 3 and a line follower 13 is such that in phase signals (disturbance signals) at the inputs of the operation amplifiers 1-3 appear unchanged whereas the difference signals are amplified. The output of each amplifier is connected via a programme selector 9 to the inputs of two differential amplifiers 6, 7, 8. The connections to the differential amplifiers are arranged so that the in phase disturbance signals cancel. The outputs of the differential amplifiers are used to control the signal reproducing devices 10, 11, 12 in the E.C.G. machine.

Abstract: 172,094. Parsons, Sir C. A., and Carnegie, A. Q. Aug. 26, 1920. Motor power plant; driving and transmission mechanism; casings.-A compact steam-turbine plant is obtained by carrying the greater number of the rows of the blades on the high speed shaft, the final rows of blades, in which a further small expansion of the steam takes place, being carried by a low-speed secondary shaft, electricallv or mechanically coupled to work in parallel with the main shaft. Thus, the main turbine portion 1, Fig. 2 having an horizontal shaft drives directly an alternator at the highest possible speed, and exhausts through a pipe 2 into a turbine section 3 which is of relatively small power and has its shaft 4 vertical or approximately so, the shaft 4 driving an alternator 7 coupled in parallel with the main alternator. The steam from the final stage passes directly to the condenser 5. The bearing 10 for the shaft 4 may be arranged as shown, or the shaft 4 may pass through the bottom of the condenser 5. The secondary shaft 4 may be horizontal and placed under the main shaft, the pipe 2 being kept as short as possible. Fig. 4 illustrates a construction wherein bevel-gearing 14, 15 is used to transmit power from the shaft 4 to the main shaft 13, and a steam admission chest 16 of volute form is employed for the secondary portion of the turbine. In cases in which the shaft 4 is vertical or inclined, the stator of the secondary portion may be divided circumferentially into several parts, each of which can be readily withdrawn, being supported during withdrawal on shelves or slide-rails.
