Title: Improvements in and relating to apparatus for reception of wireless signals and the like
IPC: H04B1/16
Filed: 1924-04-30
Abstract: 234,965. Hale, G. W., and Radio Engineering Co., Ltd. April 30, 1924. Thermionic amplifiers and detectors.-A dual amplification radio receiving circuit comprises a high-frequency input coil b connected at its high-potential end to the primary coil e of an audio-frequency transformer, the secondary coil of which is connected to the grid of a backcoupled valve d. The other end of the primary coil is connected through a crystal or like detectors g to earth, and the other end of the secondary coil f is connected to the aerial end of the primary coil e. High-frequency oscillations are conveyed to the crystal and to the grid through the capacity of the coils e, f, whilst low-frequency currents arising in the coil e from the rectifying action of the crystal are stepped up to a higher voltage bv the transformer and also applied to the grid. The plate circuit of the valve includes telephones k, battery l, and a reaction coil h for increasing the oscillations of the aerial, which is tuned by a condenser a, the only tuning element in the circuit. Low-frequency electrical disturbances are eliminated, owing to the primary and secondary coils e, f being connected to each other and both in the grid circuit, neither of them being directly connected to earth. Stages of high-frequency or lowfrequency amplification may precede or follow the dual valve.

Title: Means for compensating temperature and voltage dependence in thermistor-delayed relays
IPC: H01H47/26
Filed: 1962-03-21
Abstract: 946,637. Time delay switching circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. March 21, 1962 [March 29, 1961], No. 10785/62. Heading H2H. To reduce the effect of variations in ambient temperature and operating voltage on a thermistor 2 used to produce a time delay in the action of a relay, the thermistor is provided with a heating coil 3 energized by a second thermistor 4 connected in series with a resistor 5 across the supply U for the relay coil 1. The compensating effect may be increased by connecting a movable contact a short distance from the right-hand end of resistor 5, so that when, for example, the ambient temperature increases (at normal voltage), the voltage applied to the coil 1 and thermistor 2 decreases to augment the action of coil 3. To counteract the effect of the voltage drop across the compensating circuit caused when the relay is energized for long periods, the circuit is modified as shown in Fig. 4, in which the thermistor 2 is shunted by a contact 8 closed by energization of the relay coil 1, and the operating voltage is supplied through a contact 6a. This contact may be movable, Fig. 5 (not shown), for adjustment if two-fold compensation is not desired or if the relay is to be connected to a resistor which does not influence the voltage drop in the compensating circuit when the relay is operated. To improve the voltage compensation, the circuit shown in Fig. 1 may be modified by connecting a varistor, of the type whose resistance decreases with increase of voltage, in several ways depending on its voltage dependence and that of the thermistor 4. Thus the varistor may be in parallel with the thermistor 4, or with this thermistor and part of the resistor 5, Fig. 3 (not shown).

Filed: 1916-08-01
Abstract: 104,628. Ferguson, L. R., Wig, R. J., and McIntyre, W. A. Aug 1, 1916. Rotary batch-mixers. -To ensure thorough mixing, apparatus for mixing concrete or the like is arranged so that, after the materials have been charged into the machine, the mixer must make a predetermined number of operations or revolutions before it can be discharged. The invention is described and shown as applied to a rotary mixer A provided with pivoted charging and discharging shoots D, E. When the shoot D is raised to charge the mixer, the discharge shoot E is locked in inoperative position, and remains locked after the shoot D is lowered and until the drum A has performed a predetermined number of revolutions, whereupon it is automatically released. Upward movement of the shoot D causes a cam 2 to move a bar 1 into engagement with a pivoted cam 3 connected by a link 3<c> to an arm 3<f> on the pivot of the shoot E, and means are provided for automatically retracting the bar 1 and releasing the shoot E. One or more studs 6e on the drum A operate a tappet wheel 6<b> on a shaft 6<a> carrying a worm 6, which gears with a wheel 4<c> on a shaft 4 carrying a loose pinion 4a, which is normally clutched to the shaft and engages a rack 1<e> on the bar 1. When the bar is moved sufficient to permit the shoot E to move to the discharging position, the wheel 4<a> enters a slot 1<m> in the bar. The cam 2 is connected by a link 8<c> to a sliding rod 8<b>, which is arranged parallel to the rod 1 and carries a pivoted dog 8<a>. When the hopper D is raised, the dog 8<a> engages the arm 7b of a bellcrank lever and disengages the spring-pressed clutch 6<c> from the wheel 4<a> before the cam 2 engages the bar 1. The clutch is held disengaged until the cam 3 is locked by the bar 1 as the dog 8<a> bears against an extension 7<c> of the arm 7<b>. On lowering the hopper D, the spring-pressed dog 8<a> rides loosely over the extension 7<c> and arm 7<b>, and the spring 5<a> forces the clutch 6<c> into engagement with the wheel 4<a>. Instead of connecting the cam 2 to the hopper D, it may be operatively connected with any member that has to be shifted to admit material into the mixer, and the cam 3 may be connected with any suitable means for controlling the discharge of the mixer.

Title: Improvements in or relating to aircraft supervisory radar installations
Inventor: PEDERZANI THEODOR
IPC: G01S7/18
Filed: 1956-04-10
Abstract: 793,606. Radar. TELEFUNKEN GES. April 10, 1956, No. 10892/56. Class 40 (7). Relates to a radar system for determining the elevation or height of an aircraft and the position of the aircraft along an air route, said sys. tem comprising a plurality of pulse radars spaced along said route, each radar comprising a fan-shaped beam, shown in elevation and plan in Figs. 3 and 4, respectively, which is scanned in the vertical plane containing the route. In such a system accurate values of elevation are obtained only if the horizontal angular deviation of the craft from the centre of the route does not exceed a predetermined value # and if the lateral width of the route is x then this condition obtains for aircraft at the edge of the route only when the distance r of the craft from the radar is greater than x/2tan# ~ x/2#. According to the present invention each radar is made unresponsive to echoes from craft within an initial region 4, Fig. 3, of range r, and the radars are arranged so that the ineffective region 4 of one radar is covered by the effective region 5 of another radar. Fig. 5 shows an arrangement comprising two terminal radars 7, 17 and two pairs of intermediate back-to-back radars 9, 11 and 13, 15, the ineffective and effective regions of each radar being of equal magnitude so that the regions 10, 8, 14, 12, 18 and 16 are covered respectively, by radars 9, 7, 13, 11, 17 and 15. In Fig. 6 the ineffective region of each radar is half the length of the effective region so that the regions 23, 24, 25, 26 are covered by radars 19, 21, 20, 22, respectively. Any two adjacent radars, e.g. 9 and 11, Fig. 5, may utilize a common trigger pulse generator or common transmitter. The echoes are displayed by intensity modulation of a C.R.T. range-elevation sector display, Fig. 8, the virtual origin of the display-being offset so that the horizontal range display corresponds to the effective region. Such a local display may be reproduced at a central station by known methods or the radar data may be transmitted direct to the central station. The azimuthal position of the craft relative to the centre line of the route may be determined by using two overlapping beams, Fig. 7 (not shown), or by beam switching, the signals received in the two beam positions being applied to separate C.R.T. displays of the type shown in Fig. 8.
