Filed: 1974-02-12
Abstract: 1456083 Spectrometer display apparatus BECKMAN INSTRUMENTS Inc 12 Feb 1974  [26 March 1973] 06211/74 Heading G1A [Also in Division H4] Cathode ray tube display apparatus is adapted to display a selected portion of the range of radiant energy from a radio-active source under investigation. A radio-active sample is positioned in a NaI (Tl) crystal of a scintillation counter, Fig. 3 (not shown), the output of which is amplified and applied both direct, to the deflection control circuit, Fig. 4 and via a three channel pulse height analyzer, the effective channel of which can be selected. The direct amplified detector signal is applied via an input amplifier 92, a vertical cathode 90 follower  stage, and vertical output stage to control the vertical deflection. The sweep gate signal is fed to the horizontal deflection circuit 94 and also to the tube anode 86, for unblanking the tube for the time duration of the sweep gate signal. The circuit is designed to provide a display as shown on the right of Fig. 2. Bands 20-26 represent peak intensity signals of different pulse heights or energies, the brightness of each curve is proportional to the number of counts, and the height of the curve to the energy of the event. (The left of Fig. 2 merely represents a conventional pulse count (horizontal) versus radiation energy, rotated through 90 degrees). To provide the required display, potentiometer 108 is adjusted so that the beam of the tube starts a sweep from the left bottom side of the screen. Each event or pulse produces a curve of the form shown. The return sweep occurs below the face of the CRT. When only one channel is selected, the sweep gate 136 only receives signals representing pulses in that energy range so that other pulses are not allowed to register. In this way only one curve such as 26 may be displayed. A one-shot multi-vibrator 172 is coupled to the sweep gate and flashes a light emitting diode 178 each time an event occurs, so as to provide a qualitative activity indication.

Abstract: 271,190. Colman, T. B. March 8, 1926. Stays; double and multiple hinges.-A revolving door is provided with spacing rods or Struts that are hinged to and located between the collapsable radial wings and which act upon or carry spring catches, bolts, or abutments, that yield and permit the wings to fold together when more than a predetermined pressure is exerted upon the door. Each wing is mounted by hinges connected together by a rod c, Fig. 11, and the hinges are supported by a central column e carried by an overhead trolley, the hinge plates p about the spindles c being movable about pips q secured to the column e and the wings being pivotally mounted. The rods or struts are each pivoted at one end 4, Fig. 9, to a wing, and the other end is adapted to slide in a guideway 5 in an adjacent wing when it is released by a spring catch, shown in Fig. 13. The slipper 6 on the -strut end bears against a catch device 7, the members 6, 7 having inclined abutting surfaces, as shown, so that the slipper rides over the catch and moves along the guide 5 when an excessive pressure is exerted against the wing. Each strut is in two parts 1, 2, secured together as shown in Fig. 17, so that when a wing yields under pressure one strut slides and the parts 1, 2 of the other strut separate, as shown in the brokenline position of Fig. 9. Instead of the abutments 6, 7, the ends of the struts that slide in guideways are held by spring catches carried by the slidable fitting. To centre the wings on the hinge plates, spring catches S, Fig. 11, are provided. The hinge supports for the wings shown in Figs. 1 amd 2 comprise plates f - - i. one for each wing, enclosed in cover plates j above and below which are plates k with corners for positioning the radial wings in their normal radial position.

Abstract: 1424995 Automatic frequency control SONY CORP 13 Feb 1974 [20 Feb 1973] 6575/74 Heading H3A An automatic frequency control system for a television receiver horizontal oscillator 11 comprises a variable time constant circuit 10 connected between phase comparator 9 and the control input of oscillator 11, the time constant circuit 10 being controlled so as to have a shorter time constant during vertical blanking. periods than during other periods. The received video signal is fed to sync. separator 8 which feeds the horizontal sync. pulses to phase comparator and the vertical sync. pulses to a control input of vertical oscillator 15. The vertical blanking pulses produced by this oscillator turn off diode 10f so that capacitor 10c is not in parallel with capacitor 10d, resulting in the required shorter time constant. Alternatively a resistive element of the circuit 10 may be switched. The change in time constant reduces skew distortion when the video signal is derived from a recorder 5 instead of receiver 1 . . . 4.
