Title: Control arrangement for a heating installation
IPC: G05D23/24
Filed: 1972-05-12
Abstract: 1394070 Measuring temperature electrically W HEIERLI 12 May 1972 [14 May 1971] 22469/72 Heading G1N [Also in Division G3] In a control arrangement for a space heating installation paralleled N.T.C. (or alternatively P.T.C.) resistors 16, 17, 18 Fig. 2 are responsive to outside temperature, room temperature and input water temperature respectively and form with an adjustable resistor 15, a voltage divider. R15 is pre-set so that the volt thereacross equals the voltdrop across the paralleled sensors when the room temperature is at a required value, the respective volt-drops change capacitors 21, 22 via resistors 23, 24 respectively. When a capacitor changes to a predetermined voltage it causes a pulse to be produced by a respective pulse generator 25, 26, the pulses being of constant duration and amplitude and having a repetition rate which increases as the resistance of and hence voltage drop across the respective voltage divider portion increases. If the repetition rate of pulses from generator 25 exceeds that of generator 26, a servomotor (10) Fig. I (not shown) is caused to rotate a mixing valve (9) in one direction such that less hot water and more cold water is delivered to a heating circuit conduit. The opposite effect results when the pulse repetition rate of generator 26 is the greater, such as when the outside temperature and room temperature drop. In another embodiment Fig.3 (not shown) there are two voltage divider arrangements such as in Fig.2 each controlling a respective cold cathode tube pulse generator circuit incorporating a relay, and each including three temperature sensors and one adjustable resistor. The outdoor temperature sensor of one divider is at the same location as that of the other divider and so on, such that both dividers are subjected to the same conditions. Since the outdoor temperature sensor is subjected to greater fluctuations in temperature then the others, a resistor may be connected in series to limit its influence.

Title: Device for controlling the payment of coins in an automatic machine
IPC: G07F1/00
Filed: 1964-06-02
Abstract: 1,072,576. Coin freed apparatus. SODECO, SOC. DES COMPTEURS DE GENEVE. June 2, 1964 [June 4, 1963], No. 22720/64. Heading G4V. A device for controlling the payment of coins I, II, III, IV through a single slot in, for example, a telephone call box comprises detectors 3, 4, 5, 6 which are disposed in the path followed by the coins in such a way that each can detect the presence of a coin of certain diameter as well as that of any coin of greater diameter, and an electronic circuit for transforming the indication of the detectors into a signal, there being as many detectors as there are different sizes of coins and the signal produced having a characteristic of the number of detectors which are simultaneously affected by a coin and, as a consequence a characteristic of the monetary value of this coin. In Figs. 2 and 3 (not shown), each detector is magnetic and has concentric primary and secondary inductive windings l 1 , l 2  connected to an amplifier 12 in a resonant circuit; the leak flux from the detector is formed parallel to the axis of the windings and produces eddy currents in a coin if one is present. When no coin is present, an alternating signal is produced and this is transformed into a continuous signal of -ve polarity at a terminal E. The terminals E of each circuit are connected to respective terminals A, B, C, D of a computing circuit, Fig. 6 (not shown). When a coin of size I is present in front of the detectors, the circuit of detector 3 will cease to oscillate causing a terminal a to become +ve ; similarly a coin of size II would effect detectors 3 and 4 causing only its associated terminal b to become + ve and the rest of the terminals n, a, c, d -ve. These signals of +ve polarity can be used for crediting the value of all coins inserted. Such detectors may also be used to check the material, weight and thickness of coins to permit the rejection of faulty coins. In another embodiment, the detectors are constituted by photo-electric cells.
