Title: Improvements in or relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1927-09-30
Abstract: 278,381. Siemens & Halske Akt.-Ges. Oct. 1, 1926, [Convention date]. Automatic exchange systems. - In a finder-switch having access to lines arranged in groups, a special group test terminal 4d is provided in each group, and the first operation of the lifting magnet H serves to unlatch the test wipers c of the groups in succession and bring them into engagement with the corresponding terminal 4d. When the marked group is reached, the coupling magnet K is released, and further operation of the magnet H effects hunting over the group. The switch may be used alternatively as a call-finder or as a connector. Call-finder. The closing of the calling subscriber's loop energizes relays DK, R, the former being common to the group to which the line belongs. Relay DK marks the group test terminal 4d by applying earth over a resistance W, and connects up the starting relay E1 of an idle switch, while relav R marks the calling line in the group. Coupling magnet K energizes, and lifting magnet H operates over an interrupter U to cause successive testing of the terminals 4d by the test wipers c. When the marked terminal is found, test relay PH energizes (test relay P being inoperative on account of the resistance W), and releases coupling magnet K. Lifting magnet H now moves the wipers over the marked group, and on the calling line being reached, test relay P energizes in series with switching relay T, which extends the calling line to feed relays A, B. Relay P connects in the talking condensers. Connector. When the switch is seized bv a group selector, relay C energizes over the incoming test wire and disconnects starting relay E1. Relay A responds to impulses repeated at the preceding switch and connects up sluggish relays V1, V2 at the first impulse, and. the latter closes a circuit for coupling magnet K. The impulses are repeated to lifting magnet H and the group containing the wanted line is selected. Relays V1. V2 fall back after the first train of impulses, but only relay VI re-energizes, since the energizing circuit for relay V2 includes an off-normal contact. Magnet K is therefore de-energized, and the second set of impulses causes magnet H to step the wipers over the selected group. Relay V1 falls back at the end of the train and connects test relay P to the test wiper c. If the line is disengaged, relay P energizes first in series with relay R, and then in series with relay T, switches through and connects in the talking condensers. Ringing takes place in any known manner, and relays A, B serve as feed relays. Arrangement of switches. A relay DK is provided for every 10 subscribers' lines, and a group of 100 lines is served for example by 20 switches. When relay DK is energized, the starting circuit normally extends over back contacts of relays P, C to a particular relay E1. If however this switch is in use, one of the relays P, C is energized, and the circuit is transferred to the starting relay of the next and so on.

Title: Improvements relating to chocolate and like enrobing machines
IPC: A23G9/24
Filed: 1952-10-20
Abstract: 736,810. Electric heating. MEAGHER, W. D., and MEAGHER, G. Sept. 29, 1953 [Oct. 20, 1952], No. 26222/52. Class 39 (3). [Also in Group VI] An enrobing machine comprises a container with one or more water jackets each having an electric heating means which is regulated by a pre-set temperature controller associated with some part of the coating material delivery system and provision is made for thermostatically controlled circulation of cold water through the jacket or jackets to check further heating of the coating material after it has reached the predetermined temperature. The chocolate container, comprising " seeding " and " working " compartments 2, 3 connected by an orifice 4, has separate water jackets 5, 6 heated respectively by electric heater 17 and twin heaters 18 connected in parallel. Each of the jackets 5, 6 is supplied with mains water through a pipe 8 with a valve 9, Fig. 2, activated by a rod 10 attached to a bellows 13 connected by a tube 14 to a thermostat head 15 in the corresponding water jacket. Thus when the jackets have reached the predetermined temperatures, cold water is fed in to prevent the temperature rising further. Thermostatic cutouts 19, 20 connected in parallel and in series with heater 17 are connected respectively to contacts 21, 22 of switch 23 which are similarly connected respectively to thermostatic cut-outs 24, 25 associated, as shown in Fig. 1, with heaters 18. Molten chocolate from compartment 3 is pumped through a partly jacketed pipe 29 to a fish-tail nozzle 26 above the conveyer 27 for articles to be coated. The bulb 33 of a dial thermometer 34, forming part of an adjustable temperature controller 35, is placed in nozzle 26 or pipe 29. A contact 36 on the needle 37 of thermometer 34 is connected through the hot-wire winding 44 of a switch 42 to a further contact 38 of switch 23. A contact 39 on an adjustable pointer 40 on thermometer 34 is also connected to contact 38. When contact 43 of switch 23 connects contact 38 to the mains, current flows in wire 44 until it is heated sufficiently to close switch 42 and hence energize the heaters. Heating will continue until the temperature of the enrobing material reaches that for which pointer 40 is set whereupon contacts 36, 39 engage to short-out wire 44 and hence open switch 42 and break the heating circuit. When this temperature has been reached, thermostats 15 operate valves 9 so that mains water is fed into jackets 5, 6 to prevent further rise in temperature. When the chocolate is to be kept hot, contact 43 engages contact 22 so that current is fed to heaters 17, 18 through thermostatic cut-outs 20, 25 which are each set at the appropriate temperatures. When tempering the . chocolate, contact 43 engages contact 21 and the current supplied to heaters 17, 18 is controlled by thermostatic cut-outs 19, 24. When the chocolate is being kept hot or tempered, the mains supply of water is cut off.

Title: Improvements in and relating to electric circuits for measuring resistances, voltages or currents
IPC: G01R27/02
Filed: 1950-10-31
Abstract: 697,025. Impedance measurements; bridge circuits. BARTH, G. Oct. 31, 1950 [Nov. 2, 1949; April 3, 1950], No. 26582/50. Class 37. In a circuit for measuring resistances, impedances, voltages, or currents, the resistance to be measured, or the element of which the current or voltage is to be measured, forms part of a D.C. or A.C. network in which voltage or current dependent resistances are introduced so that their values depend on the current and voltage of the resistance to be measured. In the circuit shown in Fig. 1, a triode 1 is connected in series with a resistance 2 and current meter 3 to the negative pole of a D.C. source 4. The anode is connected to the slider 5 of a potentiometer 6 connected across the source 4. The resistance 7 to be measured is connected between the grid of the valve 1 and a tapping 10 on the potentiometer 6. The resistance 7 is thus in series with the grid-cathode gap and the resistance 2, so that the current i through the resistance 7 is the grid current of the valve. The electron gap forms a voltage or current dependent resistance, and a logarithmic change of the current i corresponds to a linear change in the grid potential. The anode voltage is adjusted by the slider 5 so that the cathode current is brought to a constant value for all values of the resistance 7. The anode voltage is then a linear function of the grid potential and the potentiometer 6 may be calibrated in anode voltage values or in values of log x, where x is the value of the resistance 7. The D.C. source 4 may be replaced by an A.C. source, a condenser being connected across the meter 3. The anode voltage may be kept constant, the current meter 3 then being direct reading. Capacitances, inductances, voltages, or currents may be measured similarly. In a modification, Fig. 3, a bridge circuit is employed, fed from a D.C. source 12. Resistances 13, 14 control the heating voltage and control grid auxiliary voltage of a valve 11. A differential galvanometer 15 has one pair of terminals connected across the bridge diagonal and the other pair has applied to it an auxiliary voltage which has a characteristic corresponding to the diagonal voltage, so that the indication is independent of voltage fluctuations. The element 16 the voltage x of which is to be measured, has its positive pole connected through a constant resistance 17 to a grid of the valve 11. With an increasing voltage the grid current increases exponentially, the resistance of the electron gap decreases, and the indication of the bridge indicator 15 increases more slowly than the voltage to be measured. As voltage or current dependent resistances electron gaps, ion gaps, dry rectifiers, saturated or premagnetized choking coils, or hot conductors may be employed.
