Title: Intrusion detector self-test system
IPC: G08B29/14
Filed: 1975-10-24
Abstract: 1466518 Intruder alarm systems UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 24 Oct 1975 [17 Dec 1974] 43701/75 Heading G4N An intrusion alarm system comprises means 12 for providing an output signal E having a first of two states under normal circuit operation, non-intrusion conditions, and the second state in response to activation of a detector 20 under normal circuit operation, clock operated means 22 for periodically providing a first signal for causing simulation of an intrusion, a second signal A for overriding the output E in its second state, and a third signal A<SP>1</SP>, a first gate 60 receiving the output signal E and the signal A<SP>1</SP> for providing an output G having a first state in response to either a normal condition, an intrusion or a simulated intrusion, and a second state in response to a malfunction, and a second gate 15 receiving the signals G, E and A for providing an output having a first state in response to either a normal condition or a simulated instrusion condition with normal circuit operation, and a second state in response to an actual intrusion or a simulated intrusion coupled with a malfunction. As shown and described, the detector 20 is a pyroelectric detector which responds to infrared from an intruder to provide the signal B shown in Fig. 2. The output of detector 20 is processed as shown to provide an output E which is normally high but is low in response to an intrusion. Under normal operation, the NAND gate 15 responds to the low E and high G to provide a high output F for actuating an alarm. The clock operated means 22 periodically provides a high signal A which is applied via a capacitor 51 to a LED 52 which simulates an intruder, and to the input of NAND gate 15 to override the simulated low output E, and to delay and integrating units 57, 58 to provide the short high signal A<SP>1</SP>. With the system functioning correctly, the output G remains high as does the other input to the gate 15 during the signal A and thus the output of gate 15 is low and the alarm is not actuated. However, if the output E remains high due to malfunction during the signal A, the output G switches low for the duration of the signal A<SP>1</SP> and thus the output of gate 15 switches high for this duration to actuate the alarm. A redundancy path including a NOR gate 70 is also provided, the NOR gate providing a high output when both its inputs are low to actuate the alarm. Should the self check signal A remain at its high level due to malfunction, thereby preventing gate 15 from functioning, upon detection of an intrusion the gate 70 responds to actuate the alarm.

Title: Apparatus for the determination of flammability and smoke  density of polymers
IPC: G01N25/50
Filed: 1971-09-20
Abstract: 1326718 Determining flammability and smoke density MICHIGAN CHEMICAL CORP 20 Sept 1971 [21 Sept 1970] 43738/71 Headings G1A and G1X In an apparatus for determining the flammability and smoke density of an organic polymer material, the material is first caused to burn in a controlled oxygen-nitrogen atmosphere in one chamber to determine its flammability and the resulting smoke is measured by optical means in a further chamber. Oxygen and nitrogen are passed, as shown, via shut off valves 14 and 16, fire metering valves 18 and 20 and flowmeters 22 and 24 to a bed of glass beads 30 in a chamber 37, from where they pass via a tube 31 to help maintain the burning of a sample polymer 34. The flammability may be determined by measuring the oxygen index which is defined as the minimum volume fraction of oxygen in an atmosphere of oxygen and nitrogen which is needed to sustain the candlelike burning of a polymeric specimen. The temperature of the sample 34 and the surrounding area may be varied by means of a heating coil 36. The density of the smoke formed by the burning is measured by a light source 40 and a photo-cell 42. A further lens 44 is provided to enable the smoke to be photographed to determine the size and nature of the particles making up the smoke. The exit 46 can provide a holder for a filter paper so that the resulting spot can be classified by its degree of darkness. The light source and the photo-cell may slidably mounted at the wall defining said second chamber.

Title: Additives for combustible organic liquids
IPC: C10L1/26
Filed: 1959-12-28
Abstract: Combustible organic liquids boiling in the range 75-750 DEG F., such as hexane, heptane, toluene, xylene, diethyl ether and bromobenzene are stablized against explosion resulting from the accumulation of electrostatic charge by the incorporation of 0.0001-1%, preferably 0.001-0.05%, by weight of a quaternary ammonium salt of phytic acid in which the quaternary groups contain 1-24 carbon atoms and are alkyl, alkenyl, aromatic or cycloaliphatic groups.  The phytic acid, i.e. the hexa-(phosphoric acid monoester) of inositol, is preferably neutralized so that the final salt contains 1-6 quaternary ammonium substituents in the molecule, especially preferred salts being the mono-, tri- and hexa-(dimethyldioleyl ammonium) phytates.  A mixture of mono-, tri-, hexa-, and dodeca-(dimethyledioleyl ammonium) phytates is obtained (Example 1) by reacting dimethydioleyl ammonium hydroxide with a solution of phytic acid in benzene and then distilling off the water formed; on subsequent evaporation of the benzene a mixture of waxy solids is obtained. ALSO: Combustible organic liquids boiling in the range 75-750 DEG F. such as petroleum naphtha, gasoline, kerosine, diesel fuel, turpentine and carbon disulphide, but especially the turbo-jet fuel known as JP-4, are rendered less likely to explode because of the accumulation of electrostatic charge by the incorporation of 0.0001-1%, preferably 0.001-0.05%, by weight of a quaternary ammonium salt of phytic acid, in which the quaternary groups contain 1-24 carbon atoms and are alkyl, alkenyl, aromatic or cycloaliphatic groups.  The phytic acid, i.e. the hexa-(phosphoric acid monoester) of inositol, is preferably neutralized so that the final salt contains 1-6 quaternary ammonium substituents in the molecule, especially preferred salts being the mono-, tri-, and hexa-(dimethyldioleyl ammonium) phytates.  The liquids may also include rust inhibitors, dyes, dye stabilizers, antioxidants, and alkyl acid phosphates, and the salt and additives may be made up as a concentrate in benzene, xylene, toluene, diethylene glycol, pyridine, or turbo-jet fuel.

Abstract: 924,860. Burners. ESSO RESEARCH & ENGINEERING CO. Dec. 6, 1961 [Dec. 30, 1960], No. 44766/60. Class 75 (1). [Also in Groups XXIX, XXXVIII and XL (c)] A vibrator more particularly for atomizing fuel oil comprises a piezo electric crystal connected in parallel with a semi-conductor PNPN device which is in series with a resistor and a source of supply whereby the crystal vibrates at its resonant frequency. The Figure shows a piezo-electric crystal 1 connected across a PNPN device 4 which is in series with a resistor 6 across an A.C. or D.C. supply 7. Coupled to the crystal is a further crystal 2 connected to the gate electrode of the diode. In operation the capacitance of the crystal 1 charges through resistor 6 until the device breaks down, whereupon it discharges through the device until the voltage across the crystal is insufficient to maintain the device conducting, whereupon it becomes non-conducting and the charging cycle recommences. The crystal 2 provides appropriate voltages for the gate electrode. Feedback to the gate electrode may alternatively be effected by a differentiating circuit connected across the output electrodes (Fig. 2, Prov.), not shown). A PNPN diode without a gate electrode may be used in which case the second crystal 2 is omitted and a resistor is connected in series between the crystal and the diode (Fig. 2, not shown). According to the Provisional Specification the crystal has a tubular capillary aperture which may be lined, one end being dipped in a constant level oil reservoir to an extent which is variable to vary the volume of oil in the spray.

Abstract: 1,125,987. Testing unattended repeaters. FELTEN & GUILLEAUME CARLSWBRK A.G. 7 Oct., 1966 [11 Jan., 1966], No. 44900/66. Heading H4R. In an arrangement for testing unattended repeaters of a 2-wire carrier system using different frequency bands for each direction of transmission, the loop gain of the repeater is tested by extracting, via a filter F 1 , Fig. 1, a signal of frequency fo from the output of the " go " channel of the repeater, doubling the frequency in the doubler VD and applying the signal, via a filter F 2  which passes the frequency 2fo, to the input of the " return " channel of the repeater. In addition, a frequency band not located within the transmitted frequency band of the system is extracted from the output of the repeater amplifier V via a circuit S and signals in this band, representing noise from the amplifier V, are rectified and control non- linear elements in the voltage doubler circuit VD to modify the level of the signal of frequency 2fo returned to the monitoring station. The rectified noise level signal from G may bias the rectifiers of the normal voltage doubler circuit VD or the rectified signal may be applied to a voltage dependent resistor arranged across the voltage doubler output. The noise band signal may be amplified before rectification in a separate amplifier inserted between the selective filter S and the rectifier G or the gain of amplifier V may be increased at the frequency selected for the noise signal by reducing the negative feedback of the amplifier at that frequency.
