Title: Digital counter frequency monitor
IPC: G01R23/10
Filed: 1960-04-12
Abstract: 892,570. Electric selective-signalling systems. ERIE RESISTOR CORPORATION. April 12, 1960 [April 24, 1959], No. 12984/60. Class 40 (1). [Also in Group XIX] In a digital frequency counter (Fig. 2) a gate 3 is controlled through gate control circuit 2 by a sensing device 1 responsive to events occurring at a nominal frequency f or period T, to be held open during successive counting intervals for N events of duration NT so as to pass NTV cycles of a clock source of frequency V = 10<SP>n</SP>f where n is the number of decimal places for which the frequency is to be counted, to a driver stage 7 operating a glow discharge decade counter having as many counter tubes 8 as there are significant digits to be counted during the interval. The ten cathodes of each tube are grounded through corresponding resistors 12 and on each cycle of clock frequency a glow is transferred from cathode to cathode until at the tenth cathode a pulse is transmitted to operate the succeeding counter tube for the next significant digit, where a similar count takes place to impulse the next succeeding counter tube after 10 digits, et seq. Each decade tube is associated with an indicator tube 13 with ten cathodes 15, each of which is connected through a cold cathode gas-discharge trigger tube 16 to a common cathode line 18 whose voltage is controlled by a gating tube 19 with anode connected to the line, cathode returned to a negative source, and grid connected to the gate control circuit 2, while the grids of the trigger tubes 16 are returned to corresponding cathodes of the counter tubes 8. After each counting interval of N events gate 3 closes and in each counter tube 8 a glow rests on the cathode corresponding to the count, while a negative pulse 20 from control circuit 2 cuts-off tube 19, and effectively grounds the cathode line 18 to cut-off any conducting trigger tube 16. A succeeding positive pulse 21 from control circuit 2 opens tube 19 to negatively energize line 18, so that the trigger tube whose grid is connected to the energized cathode of counter tube 8 immediately fires; illuminating the associated cathode in the indicator tube 13 to display the corresponding count and raising the voltage on line 18 to inhibit firing of the remaining trigger tube while maintaining the fired tube operative until quenched by the next pulse 20 at the end of the succeeding counting interval. A delay circuit 25, triggered by the pulse 21 which displays the preceding count on indicator tube 13, initiates the count over the next succeeding interval by opening gate 3, and operates reset generator 26 to zeroize the counter tubes 8. The latter are preset to register a number P = NTV+10<SP>n</SP>f and count down therefrom during opening of the gate to pass the clock frequency, so that for the nominal value of the frequency to be measured and for small deviations therefrom the frequency is displayed to the required number of decimal places.

Abstract: 752,690. Ratchet gearing. NORTHROP AIRCRAFT, Inc. May 6, 1954 [June 8, 1953], No. 13215/54. Class 80(3) [Also in Group XXXV] In an electrically-actuated ratchet device for obtaining a' step-by-step rotation in one or other direction of a shaft 4 on the receipt, by one or other of two solenoids 16, of a series of electrical pulses, the shaft 4 carries a wheel 5 on each face of which is a set of ten ratchet teeth 9 engageable by facial ratchet teeth 14, 15 on the armatures 19 of the solenoids, and ball-and-inclined-plane means 21 are provided so that when a current pulse is received by one of the solenoids its armature 19 undergoes an angular movement simultaneous with its axial movement whereby the teeth 15 engage and turn the wheel 5. The periphery of the wheel 5 has ten lobes defining detents engaged by a spring-loaded roller 10 so that the wheel 5 is located in 36-degree steps. The ball means 21 is arranged so that the axial movement of the armature 19 is accompanied by an angular movement of 45 degrees. Ten degrees of this movement are employed in bringing the teeth 15, 9 axially into engagement, a 35-degree turning movement being therefore imparted to the wheel 5. The last one degree of each step is controlled by the roller 10 while' a spiral spring returns the armature 19. The return movement is assisted by the cam action of the ratchet teeth. The spring-loaded roller 10 is carried by a collar 12 with which the two solenoids are located by pin and slot connections 26.

Abstract: 1380379 Thermisters WESTINGHOUSE ELECTRIC CORP 20 March 1973 [31 March 1972] 13311/73 Heading H1K A thermister comprises a silicon carbide wafer (Fig. 1, not shown), in which a PN junction interconnects N-type and P-type layers parallel to the major surfaces, and the wafer is grown by sublimation from a silicon carbide charge in a graphite cylinder heated in an electric furnace through a pervious wall into a graphite cavity, in which the vapour condenses into hexagonal crystals which are ultrasonically or diamond wheel divided into wafers. These may be N or P doped during growth by N, P, Sb, or Ag and Al, B respectively, and the opposed doped region is subsequently formed by diffusion or by adding dopant serially to the growth atmosphere. Major surfaces of the wafer 10 (Fig. 2) are provided with W contacts 17, 18 to make ohmic connections by high heating to form a diffusion body of carbide and silicide between the body and the contacts. The latter may alternatively be of highly doped silicon carbide. A W lead wire is Au-Ta brazed to contact 18 and a Ni steel cap 21 is similarly brazed to contact 17. A Ni steel housing 23 is slipped over connection cable 24 and attached to a similar flexible sheath containing a W wire 26 brazed to wire 19, insulated by Al 2 O 3  or MgO from sheath 25. Housing 23 is brazed to cap 21 and cable 24 and evacuated or argon filled. A bias is applied between the cable core and the case, and the variation of resistance measured by an ohmeter with temperature is logarithmic (Fig. 3, not shown). Brazing may be alternatively by Ag solder or Au-Ni alloy. The thermister may also be intrinsically heated by current therein to control its temperature, and utilized for temperature switching (Fig. 4, not shown).

Title: Apparatus for registering spiral counts
IPC: H04L1/00

Abstract: 1,039,523. Spiral-parity check-word generators. TELETYPE CORPORATION. April 4, 1963 [April 25, 1962], No. 13336/63. Heading G4A. A circuit using electromagnetic relays is described for computing a spiral-parity checkword. A spiral-parity check-word is an nbinary-bit check-word relating to a sequence of n-binary-bit words and is formed by a cyclic diagonal summation process ignoring binary carries. For a sequence of seven five-bit words the process is illustrated by the following table:- where " A " is the parity of all those bits in positions marked " a and similarly for B, C, D and E. For other sequences the process is similar. For example, for the following four words the spiral-parity check word is 10101. The circuit described computes the spiral-parity check-word of a group of 5-bit words. The 5-bit words are applied sequentially to contacts #1 to #5 in synchronism with the closures of timing contacts U, and the 5-bit check-word appropriate to the words already applied to the circuit is registered in bi-stable stages 13, 14 ... 17, and is available on leads 30. The operation of the circuit is summarised by the following table:- With the register stages 13, 14. . 17 initially cleared the 1st word is applied to contacts#1... #5, and contacts U are closed and opened. This causes the register stages to change to the conditions shown, the actual logical operation that is performed being the addition-without carries-of the input word to the existing contents of the register shifted one place to the right. Next the second word is applied contacts U are operated a second time and the register assumes the condition shown, the condition arising as follows:- 2nd word .. .. 1 1 0 0 0 existing contents of register shifted to right .... 1 1 0 1 0 sum .. .. 0 0 0 1 0 This process is repeated for the other input words.
