Title: Method of manufacturing cold-emission cathodes
IPC: C25F7/00
Filed: 1963-06-19
Abstract: <PICT:1023037/C6-C7/1> Multi-point cold emission cathodes having a number of parallel point-ended metal rods of the same length are produced by assembling the rods into the desired array and securing them to a support and thereafter forming the rods with pointed ends in the same plane by simultaneously treating each rod in individual electrolytic cells formed about each rod by a grid through the apertures of which the rods pass freely.  As shown, the rods are formed by tungsten wires 11 which are fed through the apertures of grids 1, 2, 3 and locked in the desired array by sintering a nickel powder mass 13, the grid 2 being disposed so as to avoid contact with the wires.  The free ends of the wires are then cut off adjacent the grid 3, e.g. mechanically or electrolytically, by immersing the assembly as one electrode into an electrolytic bath adjacent a counter electrode.  The grid 3 is then removed and using a NaOH solution with the grid 2 connected as cathode and grid 1 and rods as anode the rods are electrolytically cut to the same length and simultaneously tapered.  In an alternative arrangement, Fig. 6 (not shown), a length of tungsten wire is threaded repeatedly in sinuous fashion, the lower ends of the loop being brazed to a solid support for shaping treatment as above described.

Title: Method and apparatus for synchronising the local carrier oscillator in carrier frequency telecommunication systems
Inventor: SCHULZ HANSRICHARD
IPC: H04J1/06
Filed: 1968-05-22
Abstract: 1,218,467. Homodyne receivers; oscillator synchronization. SABA SCHWARZW€LDER APPARATE-BAU-ANSTALT AUGUST SCHWER SÍHNE G.m.b.H. 22 May, 1968, No. 24520/68. Headings H3A and H3Q. In a homodyne receiver, particularly for single-sideband suppressed-carrier signals, the local oscillator is synchronized by mixing it with the received sidebands and comparing the output with the difference between the fundamental modulating frequency and a harmonic thereof, or between two such harmonics. Such harmonics are present either by the characteristics of speech or due to distortion at the transmitter. In Fig. 1 the I.F. is amplified at V (which preferably contains a bandpass filter to reduce higher-order harmonics) and heterodyned at M with the output of the local oscillator 0. The I.F. is also demodulated at Q and passed through a phase-inversion stage U to a phase demodulator P where it is compared with the output of the mixer M. If the local oscillator O is not synchronized with the (required) carrier of the incoming signal the series of harmonics produced by the mixer M will be offset from the series produced by the demodulator Q by an amount representing the mistuning of the oscillator O. The phase discriminator P senses this offset of frequencies and controls the oscillator O through a reactance valve R to pull the oscillator in to the correct frequency. This is then applied to the main demodulator D of the receiver. Pulling in is facil tated by preliminary fine tuning of the oscillator, either manually or by a motor operated by the control voltage. The demodulator Q is preferably a square-law detector as this increases the harmonic content of its output and thus accentuates the required lower harmonics which are then also obtained by heterodyning among the higher harmonies. The demodulator Q may however be a linear detector or a frequency demodulator acting on the inherent phase modulation in a single sideband signal. To improve the synchronization of the oscillator O a low-pass filter is preferably included in the phase discriminator P to eliminate sum and difference frequencies above 20 Hz. The invention may be used in the reception of single or double sideband signals whether or not they are accompanied by a carrier.

Filed: 1929-08-13
Abstract: 335,684. Avery, Ltd., W. & T., and Barraclough, A. Aug. 13. 1929. Counting -apparatus; stop - mechanism. -, A counting mechanism for use with automatic weighting - machines comprises means whereby the mechanism, after being unlocked, is automatically reset at the starting point upon the completion of a predetermined series of weighings. An horizontal shaft 1]. has at its rear end a slotted arm which is oscillated by the weighing machine once for each weighing operation. Loosely mounted on the shaft but fixed relatively to one another are a ratched wheel 15 engaged by pawls 16, 17a a disc 13 with a notch 13a, and a pulley 20 which tends to rotate in a clockwise direction under the influence of a suspended counterweight 22. The pulley 20 is provided with a pair of dogs loosely engaging a pair of dogs on a boss 25a Fig. 4, carrying an arm 25 movable over a number of holes 6a pierced in the front of the casing. A setting bolt 9 may be inserted in any one of the holes. If it is desired to stop the machine after a predetermined number of weighing operations, the operator first inserts the setting bolt 9 in the hole 6a corresponding to the desired numbered of operations and then pulls down a cable 24 thus rocking a lever 14 and withdrawing a locking projection 14a from the notch 13a, at the same time temporarily liberating the pawls 16, 17a. The pounterweight 22 then rotates the ratchet wheel, notched disc and arm 25 until these are arrested by contact of the arm with the setting bolt 9. Upon release of the cable 24, the pawls are allowed to engage the ratchet wheel, and a bent lever 18 holds the lever in a raised position. The weighing operations are allowed to proceed and at the completion of each operation an arm 17 on the spindle 11 moves the pawl 17a so as to feed the ratchet wheel forward one tooth until at the completion of the series of operations the notch 13a registers with the projection 14a, and the pin 18b disengages the bent lever 18 from the lever 14 whereupon the projection 14a snaps into the notch 13a and locks the counting mechanism and thereby effects the stoppage of the weighing-machine.

Title: Improvements in or relating to automatic & semi-automatic telephone systems
IPC: H04M3/08
Filed: 1923-10-04
Abstract: 222,671. Coventry Automatic Telephones, Ltd., and Cornell, W. Oct. 4, 1923. Automatic exchange systems.-If the release of a connection is delayed either by a fault or by the calling subscriber failing to hang up, the faulty line is located by associating a distinctive condition with the connection at some extended point, for example, at the final selector, and then causing a special fault switch to hunt for the firstselector trunk employed in the connection so marked. Alternatively the switch may hunt directly for the calling line. In the system shown in Fig. 1, in which a connection has been established over a preliminary selector A, group selectors B, C, and a final selector D, one fault switch E which may be a spare preliminary selector is allotted to each group of first-selector trunks. If, at the end of the connection, the calling subscriber's feed relay 1 remains energized for a predetermined time after the release of the backbridge relay 2, an alarm is given in known manner and the particular final selector involved is indicated by a lamp. This final selector D is then marked by the operation of springs F which ground the third conductor to hold up the connection and open circuit both of the talking wires, and all the fault switches E are started up by the operation of keys 31, Fig. 2. A high-resistance relay 7 in each switch is energized to complete the circuit of the driving magnet which rotates the switch as long as either of the wipers 29, 30 finds battery on the terminal over which it passes. When, however, the appropriate switch reaches terminals 27, 28, neither wiper finds battery, so that relay 7 de-energizes to stop the switch and completes a circuit for lamp 37 over lead 35 and grounded contacts 36 at other fault switches which are still hunting. The particular first-selector trunk upon which the wipers 29, 30 have stopped is found by observation and the calling line S<1> may then be found by applying special tone to this trunk and listening for this tone on each of the lines in the group in turn. In systems in which the battery and ground connections to the line are not reversed when the called subscriber replies, the ground connection to the centre of relay 7 may be omitted. In modified circuit arrangements, one common relay 7 may be connected to each switch in turn, or one switch may commence hunting as soon as the preceding switch has hunted unsuccessfully over all the trunks to which it has access.

Abstract: 760,448. X-ray analysis. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 25, 1954 [Aug. 28, 1953], No. 24731/54. Class 40 (3). [Also in Group XX] In apparatus for X-ray analysis in which X- rays incident on an object produce secondary radiation which is reflected by a rotatable monocrystal to a rotatable radiation measuring chamber the axis of crystal and chamber being coincident, to eliminate second and higher order reflections the electrical pulses produced by the chamber have an amplitude dependent upon the incident radiant energy and the circuit comprises an amplitude filter through which the output pulses are fed. As shown, X-rays from a source 2 impinge on the specimen 1 and secondary X-rays having a wavelength spectrum characteristic of the material are emitted. Part of these rays are selected by a collimator 4 comprising a number of parallel-narrow tubes and directed to a monocrystal 6 which directs a particular wavelength of the secondary rays to a proportional counter 8 according to the angular position of the crystal. The proportional counter and monocrystal are rotatable about the axis 7 of the crystal, the angular velocity of the counter being twice that of the crystal. A further collimator 10 between the crystal and the counter moves with the counter. The output of the counter consists of pulses which vary in amplitude with the intensity of incident radiation. To select the first order reflection the counter output is fed through an amplitude filter 12 which passes pulses of amplitude between particular limits adjustable by potentiometers 13, 14. To allow for the reduction of energy in the first order reflections with the angle of rotation of the crystal, potentiometer 14 is arranged to be adjusted with the angular adjustment of the crystal. Gearing 23 may be such as to adjust the potentiometer according to a cosecant law on the potentiometer may be non-linear. By adjustment of the limits of the amplitude filter second or higher order images may be selected.
