Title: Alarm system
IPC: G08B13/22
Filed: 1975-10-15
Abstract: 1465995 Alarm systems NEWMAN-TONKS Ltd 15 Oct 1975 [5 Nov 1974] 47731/74 Heading G4N An alarm system comprises a visual and audible warning circuit 25 and a sensor 15 operable between first and second states and having a first lead 13 for connection to a power supply and a second lead 24 connected to the circuit 25, the sensor allowing current flow through the circuit 25 in one direction when in the first state and in the opposite direction when in the second state, the circuit 25 being such that warnings are given when the sensor changes state or when the leads 24, 13 are short-circuited or when the circuit 25 is open-circuited. The system described relates to a burglar alarm in which the sensor 15 includes a switch 18, 22, 23 which changes state upon opening of a window, door or door lock, and a pair of oppositely poled diodes 17, 21 which allow the current to flow through the circuit 25 in one or other direction depending upon the state of the switch 18, 22, 23. The circuit 25 comprises two pairs of diodes 26, 27 and 29, 31 connected between a supply line 14 and the lead 24, the diodes in each pair being oppositely poled and the oppositely poled diodes 26, 31 being LED's. A further pair of oppositely poled diodes 37, 38, diode 37 being a LED, are connected between the lines 24, 14 via a relay coil 36 and a reset button 35, a capacitor 33 bridging the coil and the diodes. In operation, the button 35 is momentarily pressed to energize coil 36 and latch contacts 39, 41, and with the switch 18, 22, 23 in the position shown current flows through the diodes 26, 29 and 37 only so that 26 and 37 emit light indicating that the system is activated. With the contacts 39, 41 closed, a pair of contacts 42, 43 associated with an audible warning device (not shown) are held open. Now, if the switch 18, 22, 23 changes state, due to an intrusion, current can now flow only through diodes 27, 31 and 38 so that LED's 26, 37 are extinguished and LED 31 is lit. Also, a resistor 19 is now introduced in the circuit which causes coil 36 to become de-energized thereby opening contacts 39, 41 and closing contacts 42, 43 to energize the audible alarm. To cut off the alarm it is necessary to return the sensor to its first state and operate the button 35. If the burglar tries to cheat the system by bridging leads 13, 24, the direction of current flow would no longer be governed and LED's 26 and 31 would be lit. Also the D.C. voltage across capacitor 33 will be zero and coil 36 will be de-energized resulting in the sounding of the alarm. If either or both leads 13, 24 are cut no current will flow in circuit 25 so that LED'S 26, 31, 37 will not be lit and coil 36 will be de-energized. Failure of the mains will also result in an audible alarm, and a switch 47 is provided for de-energizing the audible alarm. A plurality of sensors 15 may be provided, each having its own circuit 25, but the audible alarm being common to all the circuits.

Filed: 1971-10-19
Abstract: 1324920 Selective signalling FAIRCHILD CAMERA & INSTRUMENT CORP 19 Oct 1971 [9 Nov 1970] 48531/71 Heading G4H An electrical code-signal generator system, for operation from a keyboard, has a plurality of input lines, containing gates 13, feeding a code generator 14, two registers 16, 18 and a cyclically-operating utilization device 22 in series, the device 22 being effective to develop a cyclical signal (at 34) representative of and isochronous with its operating cycle, there being means responsive to clock pulses for transferring data from the code generator 14 to the output of the first register 16, and means 23 responsive to the clock pulses and the cyclical signal for inhibiting all the gates 13 for a predetermined minimum interval after actuation of a given key and until any data in the second register 18 has been utilized by the utilization device 22. The utilization device 22 is a tape punch, or may be a magnetic tape recorder, phototypesetting machine or computer. The keyboard key-switches 10 communicate via the gates 13 (which are flip-flops) with the code generator 14 (a diode matrix) which, besides feeding the first register 16, produces a clock pulse (at 45) from each character (and also if a switch on the keyboard indicating tape advance without data entry is actuated) to enter the code generator output into the first register 16 and supply the sync logic 23. Sync logic 23 responds to this, and a "feed punch" signal at 34 from tape punch 22, to enter the output of register 16 into register 18 and gate 20 the contents of the latter to the punch solenoids at 22. Sync logic 23 also supplies signals at 32, 33 to drive on the tape and punch a sprocket hole. The use of two registers 16, 18 permits two keys to be actuated essentially simultaneously without loss of data but then the gates 13 are inhibited until the data in 16, 18 has been passed to 18, 22 respectively.

Filed: 1967-11-01
Abstract: 1,200,099. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. Nov.1, 1967 [Nov.16, 1966], No.49579/67. Heading G3P. [Also in Division F2] A fluid-pressure differential responsive unit comprises an axially extending main body 12, Fig.2, 2, preformed in one piece with axially spaced diaphragms 14A, 14B and 14C. An inlet P1 supplies fluid-pressure to an outlet P2 or P3 according to whether PA or PB is the greater. The central diaphragm may be reinforced by embedded metal washer and the unit may be moulded in natural or synthetic rubber, vinyl or other plastics material. In Fig.3B, the unit is biased by a spring 62 and has a solid central body to close either of two inlets P1A, P1A<SP>1</SP> supplying outlets P2A, P3A. Ports 54 are provided in the upper diaphragm and the actuating pressures and supplied at PAA and PBA. A pilot valve 64 in Fig. 4 may connect an outlet port PC with an exhaust port PE or with an inlet port P1B in dependence on the relationship between actuating pressures PAB and PBB. The axial position of the port PE and hence of the exhaust valve seat may be adjusted to vary the position in which the relay is quiescent. The pressure PBB may be determined by a leak off valve 130, Fig.9 with a temperature-responsive leading element while the pressure PAB is determined by a regulator 76 having a spring load which may be varied by a mannualy rotatable helical cam. The axial adjustment of port PE allows the ratio of output to input pressure swings to be altered while revesal of the connections for PAB and PBB allows cooling as well as heating systems to be controlled. The system shown in Fig.10 provides a higher loading or reference pressure on the relay 28B during night operation. When the pressure of the main supply is raised, a relay 28A closes a conduit 164 from the regulator 76D providing loading pressure during the delay and opens a conduit 166 from the regulator 76N providing loading pressure during the night. A temperature responsive valve 120 modulates the output from the regulator 28B as in Fig.9. A relay similar to that shown at 28A may be connected to the latter by the conduit 162 and have each of its actuating pressure chambers connectible to atmosphere by a manual valve to permit the system to be set at will for day or night operation. A switch controlling a blower associated with a heat exhanger may be closed by the change of pressure when the system is set to "day". A pair of such relays may be used in a further system to reverse the reference and modulated pressure connections to the relay 28B when the supply pressure changes so that the relay 28B may control a cooling instead of a heating medium.

Title: Catalyst and process for effecting condensation of hydroearbons
IPC: B01J37/00
Filed: 1963-12-23
Abstract: Aromatic hydrocarbons may be alkylated or transalkylated, isoparaffins may be alkylated, and olefins polymerized using a catalyst prepared by treating a fluorine-containing refractory inorganic oxide composite having a Hammett acidity function value of less than -8.2 with a substantially anhydrous oxygen-free inert gas at a temperature between 450 DEG  and 700 DEG  C.  The preferred oxide is alumina, and the fluorine content of the catalyst may be 2-12% by weight of the oxide.  Suitable conditions are indicated for each type of reaction. Compounds which may be alkylated include benzene, lower and higher alkyl-benzenes, diphenyl, diphenyl methane, naphthalene, alkylnaphthalenes, anthracene, phenanthrene, naphthacene and rubrene; and the alkylating reactants include olefins, polyolefins, acetylenes, alcohols, ethers, esters, alkyl halides, alkyl sulphates, and alkyl phosphates.  A combined alkylation/transalkylation/separation process may be carried out using the above catalyst, in which effluent from an alkylation reaction and comprising unreacted aromatic, monoalkylated aromatic and polyalkylated aromatic, is fractionally distilled to recover the required monoalkylated aromatic, and the remaining unreacted and polyalkylated aromatics are then passed to a transalkylation zone where more monoalkylated aromatic is produced, the effluent from this zone being combined with the alkylation effluent and fractionally distilled together therewith.  Polymerization reactions may be carried out on mono-, di- and cyclo-olefins, particularly to form gasoline from propylene and butylenes, and propylene trimer, tetramer and pentamer. Examples relate to: (6)-(10) transalkylation of benzene and diisopropyl benzene to cumene, including a combined process as described above; (11) alkylation of benzene with ethylene; (12) alkylation of benzene with refinery off-gas containing 10% ethylene; (13), (16) and (18) polymerization of a propane-propylene mixture to propylene trimer and tetramer; and (17) polymerization of a butane-butylene mixture to octenes.ALSO:A hydrocarbon condensation catalyst comprises a fluorine-containing refractory inorganic oxide composite which has been treated with a substantially anhydrous oxygen-free gas at a temperature of between 450 DEG C. and 700 DEG C., and which before the treatment had a Hammett acidity function value less than -8.2. The catalyst may contain from 2% to 12% by weight of fluorine. Silica and silica-alumina catalysts are exemplified; also mentioned are silica-alumina-magnesia; silica-magnesia; silica-zirconia; alumina - zirconia; alumina - boria; zirconia; titanium oxide.  The composite may be calcined in air at a temperature above 400 DEG C. before treatment.  The oxygen-free gas is preferably nitrogen or hydrogen; also mentioned are helium, neon, argon, krypton and xenon.

Filed: 1976-12-06
Abstract: The internal-gear pump suitable for pressures up to approximately 150 bar is driven via a pinion shaft (14). Between a pinion (15) and a ring gear (16) there is a semicrescent-shaped filler piece (20) capable of limited free movement. The filler piece (20), together with the gear wheels (15, 16), delimits a discharge chamber (19) and, counter to the direction of revolution, with one bearing face (23) bears on a filler-piece pin (21) fixed within the casing. The ring gear (16) is supported, in the region of the discharge chamber (19), directly in the casing (10) by its outer shell surface (17). The distance (x) between the bearing face (23) of the filler piece (20) and the axis (24) of the filler-piece pin (21) is adjustable, in order to ensure that the filler piece (20) rests snugly against the tooth tips of the gear wheels (15, 16), so as to be able to compensate in a simple manner for dimensional deviations and/or production tolerances as well as for play resulting from wear. This means reduced operational and production costs. <IMAGE>
