Abstract: 1522322 Air-heater-blower for ventilating an underground installation T A PELSUE CO 28 Oct 1975 [31 Oct 1974] 44280/75 Heading F4S and F4V A portable heater-blower assembly 10 (e.g. for blowing air through a manhole 16 into an underground installation) has (a) a blower subassembly 12 comprising an electric-motor driven fan (52, Fig. 2, not shown) and (b) a heater sub-assembly 14 comprising two gas burners 66, Fig. 8, (one only being shown in this figure) which are actuated electrically by means of circuitry illustrated in Fig. 13 (not shown). The circuitry includes switches (90, 94) which actuate valves (86, 84, Fig. 12, not shown) whereby gas can be supplied to just one or to both burners, an igniter 92, Fig. 8, a flame sensor 96 and a thermal switch 98, Fig. 5, which stops operation of the burners in the event of overheating. The two sub-assemblies 10 and 12 can be transported separately and then be coupled together for use. An outlet 22 from the blower subassembly telescopes into an inlet 38 to the heater sub-assembly, and is held in position by a spring latch 40. Electric power is supplied to the blower sub-assembly by a cord 24. The electric power required by the heater subassembly is taken from the blower sub-assembly via a socket 32, Fig. 5, plug 30 and cord 28. The arrangement is such that, when the air inlet 38 of the heater sub-assembly is connected to the air outlet 22 of the blower sub-assembly, the plug 30 cannot be disconnected from its operative position, disconnection being prevented by a step 34 in a base 36. Hot combustion gases from the burners 66 pass through heat exchangers 100, Fig. 8 (and Figs. 11 and 12, not shown), while the air to be heated flows over the heat exchanger's external surfaces. The spent combustion gases are exhausted through a chimney 70.

[Also in Divisions G1 and H2] The rate of flow of molten metal from a container 1 is automatically maintained constant by varying the energization of an electromagnetic device 2 in accordance with the depth of metal in the container. The depth may be measured or computed on a time basis from a known initial depth. The temperature of the metal and the rate of wear on the outlet nozzle may also be taken into account. In one embodiment, a reversible motor 4 automatically maintains an electrode 3 in intermittent contact with the surface of the metal and simultaneously adjusts the slider of a potential divider 8, the output voltage of which (subject to an undisclosed form of compensation for electrode wear) controls a current source 9 which energizes the device 2. The motor 4 is controlled by reversing relays (13), (14), Fig. 2 (not shown), according to the presence or absence of a voltage between the electrode 3 and the earthed mass of metal. Delay devices (16), (17) are included in series with each relay. In a second embodiment, Fig. 3 (not shown), it is assumed that the initial depth of the molten metal will always be the same, a formula is given relating the pressure to be exerted in the flow to the density of the metal, to initial depth, the initial diameter of the outlet nozzle, the rate of wear on the nozzle and the time for tapping the metal, and it is stated that an analogue computer will supply such a signal to the flow controlling device.

A matrix data store comprises bi-stable devices each having first and second inputs connected to row and column conductors, respectively, energization of said first input without simultaneous energization of said second input setting the device to its first stable state and simultaneous energization of both inputs setting the device in its second stable state. In the particular embodiment, each bi-stable device is a mercury wetted reed relay with biasing magnet and two coils P and T. The relay contacts are biased closed. Energization of coil T alone will open them, when they will remain open. Energization of both coils P and T will close them, when they will remain closed. A word is read into the store by energizing a row winding (connected to the T coils) and those column windings (connected to the P coils) corresponding to ONE bits. Contacts will thus be opened to store each ONE bit and contacts corresponding to other bits in the word will be closed. Separate resetting of the row prior to read-in is thus not necessary.

Filed: 1975-10-31
Abstract: 1529874 Automatic level control for photosensors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Oct 1975 [7 Nov 1974]  45308/75 Heading G1A Apparatus which monitors the transmission of infra-red pulses between a source 3, Fig. 1, and a detector 9 has an automatic level control for setting the detector output; the level control signal is the integral of the error between the detector output and a reference derived from the source. The error signal is also integrated and thresholded to allow large or sudden changes of transmission to be distinguished from changes in ambient illumination etc., an alarm being activated accordingly. The source is driven by a multi-vibrator 1 and pulse shaper 2, and transmits a beam towards an object 5 to be monitored. Reflected pulses are detected at 9 and pass via gain control 6 and amplifier 8 to a comparator 7 where they are synchromously compared with pulses direct from source 3. The comparator is activated only during source pulses, under control of signals on line T, and produces error control pulses at A 1  and A 2  if its two inputs A and B differ; the control pulses at A2 are rectified and integrated at 11, and drive the gain control 6 to balance these inputs. The control pulses are also integrated at 12, and if a threshold is exceeded an alarm 14 is activated. The activation is performed by two hold circuits, Fig. 2 (not shown), an inverter and an AND gate, which together determine how long the activation lasts. The first hold circuit also lights a lamp 13 during the time between initial switch on of the apparatus and the moment when it is balanced and ready for use. To allow balancing when the monitored object is non-reflective, e.g. a hole in a wall, the source and detector have a direct electric connection in Fig. 1 so that the detector circuit always produces pulses. A detailed circuit diagram of all the components of Fig. 1 is given, Fig. 3 (not shown).
