Abstract: 642,526. Exchange systems. STANDARD TELEPHONES & CABLES, Ltd. March 9, 1946, No. 7404. [Class 40 (iv)] By dialling an appropriate code before the wanted number, a calling party can determine that the charges incurred in making a longdistance telephone or teleprinter call shall be communicated to him automatically. The communication may take the form of a reproduction of speech or of a teleprinter message. By dialling the code 010, the caller gains access to trunk selectors over line-finder IF, selectors 1S, 2S, 3S and a non-numerical switch LDS. The switch LDS is associated with ticketing equipment TE and a ticketing machine TM arranged as described in Specification 510,012. By dialling the code 019 instead of 010, the connection to LDS is made through announcing equipment AE. When both parties have released, AE is found by the line-finder IF and a connection is set up under control of the calling party's number recorded in TE as described in Specification 642,527 and the charges are announced. Operation. When AE is seized from 3S, A operates and is followed by B and H. Relay B is held by ground on TL so long as the caller is on the line and H is held independently by TE. The caller is connected to LDS over h1, h2. When the call is finished, B falls back and at b4 extends a loop to the line-finder IF. Relay I is operated by impulses from TE corresponding to the caller's number which are repeated at il to set up the connection to the caller again. When the caller replies, M operates and at ml, m2 switches the talking wires to announcing equipment. One sound record R1 (Fig. 3) is common to all calls and when reproduced, leaves suitable gaps to be filled by reproductions from records R1, R2, &c. of details appropriate to the call. The records R1, R2, &c. are selected by TE. Specifications 498,374, 511,695, 513,285 and 513,286 also are referred to.

Title: Heating and or cooling apparatus
IPC: F24F11/00
Filed: 1973-02-19
Abstract: 1418828 Ventilating and heating or cooling buildings; air heating stoves MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Feb 1973 8105/73 Headings F4V and F4S [Also in Divisions G1 and G3] In a central heating or cooling apparatus for supplying warmed or cooled air to a plurality of rooms A, B, C, D (Fig. 1), via respective ducts 4a to 4d using a heat exchanger (11), Fig. 10 (not shown), and blower fan (18), the temperature and volume flow rate or pressure of air in a main duct 2 are sensed and maintained constant by control of the fan speed and fuel supply to a burner, for example, when heating. Thus if a louvre 5a is closed to stop warm air supply to room A the resulting tendency for the temperature of the other rooms to rise is prevented by reducing the total flow rate and temperature of air in duct 2. Control circuit, Fig. 11.-The air flow rate in duct 2 is sensed by a pressure transducer (Figs. 6, 7, 8) comprising a diaphragm acting upon a pair of resistance strain gauges 57, 58, one of which is in tension while the other is in compression. When the load is zero both gauges have the same resistance. The gauges 57, 58 are connected in a bridge together with R70, diode 69, R71, R72. A transistor 73 senses the bridge unbalance, charging a capacitor 74 accordingly, the charging time of C74 varying inversely with the deviation in detected pressure from required pressure pre-set on R70. When C74 is sufficiently charged a UJ transistor 76 fires and triggers an SCR 66 connected in the diagonal of a diode switching bridge. The fan motor 18 is energized accordingly. The smaller the deviation, the greater the charging time of C74 and the greater the firing angle of the SCR and hence the lower the fan motor speed. The duct temperature is sensed by a P.T.O. thermistor 27 and desired temperature is pre-set on R87 both connected in a bridge with resistors 84, 85, 86. The bridge unbalance controls a transistor 88 which in turn controls a transistor 82 in series with a coil 83 of an electromagnetic valve of the burner fuel supply. Alternatively, the heat source may be an electric heater (Fig. 12, not shown).

[Class 40 (iii)] The amplitudes of the deflections of a reproducing beam in a cathode ray tube are so adjustable that the whole of the picture or a magnified part can be reproduced. (i) To centre the desired portion, a variable bias current is set up in deflecting coils L1, L2 by applying a controlling voltage between a pair of opposite points A, B in a resistance loop, which are adjustable relatively to another pair of opposite points C, D in the circuit of the deflecting coil. Each set of deflecting coils is in series with the secondary winding of a time-base output transformer T1, T2 and a pair of low-resistance potentiometers PI, P4 in parallel, Fig. 2 (not shown). The movable contacts on the two potentiometers are so ganged that when one is moved towards one common terminal, the other contact moves towards the other common terminal. The potentiometers may comprise wire wound on a common arcuate support and angularly related contact arms on a common spindle, Fig. 3 (not shown). (ii) The amplitudes of the deflections are made adjustable in steps by means of switches for inserting gain-controlling resistances in the timebase circuits. (iii) When the deflecting amplitudes are adjusted to a minimum, the centring device is automatically disabled or set to centre the whole picture on the screen by switches, which remove the adjustable biases from the deflecting systems and are coupled with the magnifying controls. (iv) The magnifying and centring controls are at a viewing point away from the cathode-ray tube. Specification 520,234 is referred to.
