Title: Apparatus for detecting the presence of suspended matter, such as smoke, in the air
IPC: G01N21/53
Filed: 1965-07-08
Abstract: 1,090,777. Photo-electric smoke detectors. G.A. ROBERTS. July 8, 1965 [July 13, 1964], No.29043/65. Heading G1A. A smoke detector operates on the principle that light scattered from the smoke particles increases the illumination of a photo-cell, operating an alarm. The apparatus comprises a casing, containing the alarm circuit components, a lamp 44 (Fig. 1), located at one end of a light transmission conduit, containing a lens 64 and various aperture plates 56, 68, 70 and directing light into a light trap 92, and a photo-sensitive resistor detector 96. Various apertures for entry and exit of air are provided in the casing, the components and lamp being mounted so that normally a convection current of air flows through casing. Suitable light baffles are also provided. Normally little light is scattered towards the detector 96, mounted out of the direct light path, but when smoke is present, it is illuminated, causing a reduction in its resistance. The detector is arranged in a bridge circuit, two arms of which comprise the detector itself and a resistor 104, the other two capacitors 124, 126 of equal magnitude or a certain ratio. When the photo-resistor 96 decreases to the value of resistors 104 or a predetermined value proportional to it, the silicon controlled rectifier 122 is switched on, energizing a relay 128. This closes contact 128 and a buzzer 110 is energized. A temperature sensitive switch 112 is provided. An alternative circuit Fig. 5 (not shown) is arranged to switch off automatically when the smoke has dispersed, whereas in the case of the circuit of Fig. 1, this has to be done manually by breaking the supply current. An alternative casing construction is also described Fig.4 (not shown).

Abstract: 1,213,949. Absorption refrigeration systems. CARRIER CORP. 12 June, 1969 [30 July, 1968], No. 29886/69. Heading F4H. An air cooled continuous cycle absorption system utilizing a lithium halide as absorbent and water as refrigerant includes two seriesconnected adiabatic evaporators each communicating with an absorber, liquid refrigerant from the evaporators being passed through a cold output heat exchanger and then returned to one of the evaporators. As illustrated, refrigerant from the generator 10 passes through a condenser 11 to the higher temperature evaporafor 12 in which about 1% of the refrigerant evaporates to be absorbed in the high-pressure absorber 14. Cooled refrigerant passes to the lower temperature evaporator 13 in which a further 1% evaporates to be absorbed in the low-pressure absorber 15. The absorbers consist of a plurality of vertical finned tubes and are separated by a siphon 40 to maintain the required pressure difference. Cold liquid refrigerant from the evaporator 13 is passed by a pump 97 to the output heat exchanger 16 from which it returns to the high-temperature evaporator 12. Weak solution from the highpressure absorber 14 is passed by a pump 62 through a liquid heat exchanger 17 to the generator, from which strong solution is passed by a pump 31 to the low-pressure absorber 15.

Abstract: 1434244 Pulse width discriminator KOMBINAT MEDIZIN - UND - LABORTECHNIK VEB 22 June 1973 [23 June 1972] 29895/73 Heading H3P [Also in Division G1] In apparatus for the pulse method of measurement of dispersion values of particles dispersed in a suspension comprising a transducer having a measuring opening arranged to provide electrical output pulses related to the dispersion values of the particles dispersed in the suspension in response to the passage of the particles through the opening and a circuit arrangement for evaluating the pulses derived from the transducer, the circuit arrangement either reduces the areas of derived pulses relating to particles flowing through the measuring opening adjacent the perimeter of the measuring opening or suppresses the derived pulses to exclude them from the formation of a measuring value, the derived pulses relating to all other particles flowing through the measuring opening passing unvaried through the circuit arrangement. The circuit arrangement comprises a gate 1, Fig. 1 for the derived pulses, a multivibrator 3 controlling the gate 1 and a differentiating element 2 responsive to the derived pulses and arranged to trip the multivibrator 3. In Fig. 1 the differentiating element 2 produces a pulse (Fig. 2, not shown) from the leading edge of an input pulse so as to trigger a monostable multivibrator 3 into its unstable state. The monostable multivibrator 3 opens the gate 1 for the duration of its unstable period so as to completely pass input pulses of width less than or equal to this unstable period. Input pulses of greater width are shortened. In a further embodiment Fig. 3, a differentiating element 2 produces positive and negative going pulses (Fig. 4, not shown) from the leading and trailing edges of the input pulses. The positive pulse triggers a monostable multivibrator 4 into its unstable state, and the negative pulse is passed via a NOT or inverter element to provide a positive input to an AND element 6. Provided the input pulse width is less than or equal to the unstable period of the multivibrator 4 the AND element produces an output to operate a bi-stable multivibrator 7 which opens the gate 1 so as to allow the input pulse delayed in a delay circuit 8 to pass to the output. The bi-stable multivibrator 7 is reset by a negative pulse obtained from a differentiating element 9 corresponding to the trailing edge of the delayed pulse from 8. Input pulses of width greater than the unstable state period of the multivibator 4 do not energize the AND element 6 so that the gate 1 remains closed and no output is obtained.
