Patent GB-1455713-A (GB)
Title: Optically-coupled sensing system
IPC: B66B13/26
Filed: 1973-11-20
Abstract: 1455713 Door control mechanisms INNOVATION INDUSTRIES Inc 20 Nov 1973 [20 Nov 1972] 53857/73 Heading E2M [Also in Division G1] An area, for example the doorway of a lift, is photo electrically monitored by two spaced light beams; these beams are formed by a periscope-like pair of mirrors 26, Fig. 1, which receive an incoming light beam 34 from an LED 14 via lens 22 and directs it to a detector 58 via lens 42 and filters 46, 50. The LED emits infra-red radiation which is partially collimated by lens 22; the detector 58 is positioned to lie between lens 42 and its focal point, this arrangement of lenses 22 and 42 ensuring that alignment is not critical. Visible radiation is prevented from reaching the detector by the crossed polarising filters 46, 50. The detector output drives a door operating relay and also another LED 76 the illumination of which varies with alignment of the apparatus and which can thus be used in setting up. Circuitry: the LED 14 is pulsed by generator 6, which also drives a gate 74 via a delay device 78; the detector signal passes via high pass filter 62 and amplifier 66 to gate 74, the delay at 78 being such that the gate 74 is opened only when a light pulse should be received by the detector. The signal passes via the gate to a set/reset device 82 where the pulses are converted to a substantially DC signal to drive door relay 88. If an object blocks the light path the DC level changes and the relay will change over. The amplifier 66 has a threshold which is determined by the DC level, Fig. 2 (not shown), to provide a degree of hysteresis. A timer 92 overrides the system and closes the door if the light path remains blocked too long; this is so that in the event of a fire the lift is not made unworkable by smoke in the light path.

Title: Process for Producing Adiponitrile
IPC: C25B3/29
Filed: 1966-12-01
Abstract: 1,170,436. Preparation of adiponitrile. ASAHI KASEI KOGYO K.K. 1 Dec., 1966 [3 Dec., 1965; 13 Dec., 1965], No. 53870/66. Heading C2C. [Also in Division C7] Adiponitrile is obtained by electrolysing an aqueous solution containing acrylonitrile and a quaternary ammonium compound wherein the quaternary ammonium cation is a tetra-alkyl ammonium cation in which the alkyl groups contain 1 or 2 carbon atoms and the anion is a halogen ion or a monoalkylsulphate ion in which the alkyl group has less than three carbon atoms, at a pH below 7, said acrylonitrile being present in a concentration of from 3 to 10% by wt. and said quaternary ammonium compound being present in a concentration of less than 30% by wt. The electrolysis is suitably carried out in a cell divided by a cation exchange membrane to provide separate anode and cathode compartments in which the anolyte employed is an acid. The solution containing the acrylonitrile, which may also include a polymerization inhibitor, is preferably circulated over the cathode.

Title: Method of heating metal parts particularly steel ingots or the like in soaking furnaces particularly pit type furnaces and a burner arrangement for carrying out the method
IPC: C21D9/70
Filed: 1970-11-13
Abstract: 1329578 Burner arrangement and control for soaking furnace SOC ITALIANA IMPIANTI SpA 13 Nov 1970 [15 Nov 1969] 54210/70 Headings F4B and F4T A burner control system for controlling the heating of steel ingots in a pit type soaking furnace 1 heated by a burner arrangement comprising two coaxial burners defined by air chamber 5 and outer fuel tube 7, and inner fuel tube 8 and intermediate air tube 7 respectively, each burner being provided with respective fuel supply pipes 11, 15 and air supply pipes 9, 14, includes means controlled automatically upon the furnace wall reaching a temperature higher than the surface melting temperature of the ingots to throttle the air and fuel supply pipes to the outer burner causing a consequent increase in pressure in the supply pipes of the inner burner and an increased admission speed of combustion gases into the furnace during the initial stages of the soaking period, thus maintaining or increasing turbulence, initiated by inclined air supply nozzle 10, and uniformity of temperature distribution in the furnace, the ratio of fuel to combusion air remaining constant for both burners. During the soaking period heat is conveyed to the ingots by radiation from the superheated furnace walls, by convection induced by intensive turbulence, and by the direct output from the remaining operational burner which is fuelled by any gaseous fuel or fuel convertable into gaseous form, e.g. liquid or pulverized fuel. Air supply pipes 9, 14 are connected to a common manifold 16 supplied by blower 17 and similarly fuel supply pipes 11, 15 are supplied by blower 19, the supply pipes 9, 11 to the outer burner having electrically operable throttle elements 20, 21 controlled in response to temperature sensor 24. Flow measuring devices 27, 29 and controller 28 ensures a constant fuel/air ratio for combustion. During an initial heating period throttle elements 20, 21 are open and both burners operate at full power. When the walls of the furnace reach the required temperature sensor 24 acts to gradually close throttle element 20, controller 28 consequently and simultaneously closing throttle element 21 to shut down the outer burner, thus creating a pressure rise in the supplies to the inner burner. As the ingot heats and the furnace walls cool a uniform final temperature is established at which control device 26 and sensor 24 act to close throttle element 22 and, via controller 28, throttle element 23 to shut down the inner burner completely and terminate the soaking period.

As shown, there are four punches (5-8), Fig. 4 (not shown), and four dies (1-4), Fig. 1 (not shown), the punches being attached by piston-rods 14-17, Fig. 3, to annular pistons 10-13, the inner pair 11, 12 of which have rearwardly-extending valve-sleeves 20, 21, Fig. 2. An edge 27 on a housing 18 co-operates with ports 22, 23 in the sleeve 20, and an edge 25 on the sleeve 20 co-operates with a port 24 in the sleeve 21. Operation.-Pressure fluid supplied to one side of piston 10, through a side-port 19 in the casing 18, advances the four pistons together through the first die (1) and up to the second die (2) when port 22 is uncovered by the edge 27. A passage in the sleeve 20 leads from the port 22 to the second piston 11 and to the other side of piston 10 so as to continue advance of the pistons 11, 12 and 13 and reduce the force assimilable at the outer punch (5) for pressure on the second die. Similarly, when port 23 is uncovered, the pistons 12 and 13 continue to advance and the force available for holding by the punch 11 is reduced. Piston 13 advances alone when port 24 is uncovered by edge 25. The pistons 10, 11 and 12 are returned by piston 13 when pressure fluid is supplied through a port 40 in a central guide tube 39.
