Title: Preparation of fuel gas
IPC: C10G9/00
Filed: 1961-10-09
Abstract: Fuel gas of high calorific value is made continuously in an apparatus in which a hydrocarbon fluid and a carrier gas are introduced into a reaction zone externally heated by a heating gas, and the products are passed to a fixing zone similarly externally heated.  The hydrocarbon fluid may be gaseous, e.g. propane or butane, or liquid, e.g. low grade hydrocarbon oils or high grade gas oils, and the carrier gas may be steam or combustion products from the process.  As shown the apparatus comprises a reactor shell 10 of height 150-920 cms. and equivalent diameter 150-460 cms. surrounding a reactor chamber 17 extending substantially the full height of the shell and of equivalent diameter at least half thereof; a fixer shell 51 of height and cross-section in the same range as the shell 10 encloses a fixer chamber 45 of the same range of height and equivalent diameter as the chamber 17 and contains refractory material 61.  The chambers and shells need not be of circular cross-section; "equivalent diameter" is the diameter of a component of circular cross-section and the same cross-sectional area.  A nozzle 39 supplies hydrocarbon gas or liquid to the chamber 17 and <PICT:0988583/C4-C5/1> means at 34 and 28 respectively supply carrier gases and combustion gases thereto.  The chamber 17 is connected to chamber 45 by a conduit 11. Product gas from chamber 45 passes out through a conduit 13 and a washer 15.  Hydrocarbon gas or oil is supplied to chamber 17 through the pipe 39, and steam through a line 34 and nozzle 35.  When heavy oils are treated a constriction 41-44 of refractory material is provided in the chamber 17. Fuel, e.g. oil, and air for external heating, are supplied through pipes 28 and 29 respectively and the mixture is burnt in a chamber 27 which contains baffles 31, 32, and leads tangentially into the heating jacket 22.  Combustion gases pass from jacket 22 to jacket 51 via a pipe 36 opening tangentially into both jackets. Additional fuel is burnt in a chamber 52 having baffles 55, 56 and opening tangentially into jacket 51.  The products from the heating jackets pass to a stack or waste heat boiler via port 57 and pipe 58.  The gravity of the make gas is controlled by an instrument 70 through which a portion of the gas passes and which is so connected as to pass make gas back to reactor zone 17 via a line 63 and flow control apparatus 64, or to divert combustion gas from pipe 36 to the inlet line 34 via a flow control device 37 and a line 38, according to circumstances. The calorific content of the make gas is controlled by a calorimeter 71 which, according to the construction of the make gas passing through, opens or closes a valve 71a in the gas or oil inlet 39.  The refractory material 61 includes a pyrometer 72 which maintains the desired temperature gradient in the apparatus by adjusting the fuel supply to the chamber 27. The walls of the reaction chamber 17 and the fixing chamber 45 may be of carborundum or stainless steel or other alloy.

Title: Printed circuit board tester
IPC: G01R31/28
Filed: 1976-09-02
Abstract: 1523060 Testing printed circuit boards HONEYWELL INFORMATION SYSTEMS Inc 2 Sept 1976 [5 Sept 1975] 36370/76 Heading G1U A tester for printed circuit boards comprises first means for making a sequence of tests to detect faults on a board under test, and second means which operate when a fault is detected is carry out a sequence of tests to locate the fault, said second means including a movable probe, a control for moving the probe to a sequence of points on the board, and means for conducting a test at each point and indicating failure of the test. Insertion of a printed board into a test head 504 automatically signals the control system minicomputer 501 to switch from an 'idle' mode to a 'clear' mode, in which all registers are set to zero. After this clearing, a 'request data' mode follows during which under the control of front panel 508, 509 settings, a date source e.g. tape reader 507, computer 503 is signalled to provide information on the board under test. This data is loaded into the appropriate register, and the system then moves into an 'execute test' mode. Here, stimuli which might be A.C. or D.C. signals, digital levels or words or clockpulses are applied to the board and the resulting outputs examined for a GO/NO GO result. If a NO GO result occurs, i.e. a fault is indicated, stored results are dumped, and the system minicomputer signalled to initiate a fault location sequence appropriate to the fault found. If a GO result obtains, more data is requested if further tests are required, or the test results are stored if this is the last test. In the fault location mode, a movable probe (2708) Fig. 27 (not shown), is moved under the control of the minicomputer by motors (2709-2711) to sequentially contact test points backwards into the circuit under test from the fault point. At all test points, the possible paths to adjacent test points are tested to establish a fault "path" which terminates at or near the fault. The nature of the fault output a fault path is then analysed to identify the actual faulty component. Full details of control analysis and timing circuits are given in the Specification.

Title: Process of manufacturing thermosetting molding powder
IPC: C08L61/20
Filed: 1962-09-25
Abstract: In a dry process for making thermosetting moulding compositions wherein a reaction product of formaldehyde and urea, thiourea or melamine or any mixture thereof is combined in the presence of water with a cellulosic filler to provide a moist, plastic mixture and the mixture is dried, densified and granulated to form a moulding powder, the improvement comprises rapidly removing most of the water from the moist mixture while it is in a finely divided state and highly agitated in many times its volume of a suitable gas, e.g. air, nitrogen, helium or chloromethane.  The initial resinforming reaction is effected, as described in Specification 785,976, by introducing the aminoreactant, alkaline catalyst, e.g. ammonia or hexamine, and paraformaldehyde or concentrated formalin, together with the filler, into a closed mixing zone and heating the mixture, e.g. at 170 DEG to 180 DEG  F., until the desired state of condensation is reached; the reacted material is then rapidly cooled and the resulting flowable moist powder is subjected to the above drying treatment.  A suitable drying apparatus is that described in U.S.A.  Specification 2,752,097 or a modification thereof in which a hollow shaft in the rotor is used as a feed instead of the screw feed (see Division B1). The cellular filler, e.g. alpha-cellulose or wood flour, may be replaced in part by walnut-shell flour, sulphite, pulp, glass-fibre, keratin or regenerated cellulose, and biuret may in part replace urea, melamine or thiourea.  The preferred curing catalyst is epichlorohydrin, and can be added at any stage in the preparation of the moulding powder.ALSO:In a dry process for making thermosetting moulding compositions wherein a reaction product of formaldehyde and urea, thiourea or p  melamine or any mixture thereof is combined in the presence of water with a cellulosic filler to provide a moist, plastic mixture and the mixture is dried, densified and granulated to form a moulding powder, the improvement comprises rapidly removing most of the water from the moist mixture while it is in a finely divided state and highly agitated in many times its volume of a suitable gas, e.g. air, nitrogen, helium or chloromethane.  A suitable apparatus is described, which is a modification of that described in U.S.A.
