Title: Process for the production of finely divided oxides
IPC: C01B13/14
Filed: 1972-10-27
Abstract: 1412472 Oxides by vapour phase hydrolysis DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 27 Oct 1972 [28 Oct 1971] 49567/72 Heading C1A Finely divided metal and silicon oxides are produced by vapour phase hydrolysis in a flame supplied with a mixture of halide O 2 , and gases which burn to form H 2 O, the burner being surrounded by an annular nozzle supplied with H 2  to prevent formation of deposits on the burner, and additional steam being introduced or generated around the flame. The steam may be superheated and may be introduced through a silver ring nozzle situated either in the gap between the burner and an open flame tube, or in the flame tube itself. Alternatively additional H 2  may be introduced to burn with secondary air and form steam in situ. This H 2  may be introduced through the nozzle as for steam, or excess H 2  may be supplied through the annular nozzle. An inert gas, e.g. N 2 , may be added to the halide-containing gas mixture. The exemplified reactants fed to the burner are SiCl 4 , H 2  and air.

Abstract: 988,657. Regulating I.C. engines. A. MIZUNO. Dec. 16, 1963 [Dec. 26, 1962], No. 49655/63. Heading FIB. [Also in Divisions B7 and F2] In an r.C. engine throttle control device, the throttle spindle 3, Fig. 1, is connected by linkage 4, 5 to an electromagnet 7, Fig. 2 which, when energized, is attracted to and maintained at a desired position on a ferromagnetic plate 12 displaceable by a motor 14 to regulate the throttle. A switch S1 Fig. 3 controls the electromagnet 7 and switches S1, S2 control the direction of rotation of an electric motor 16 (14 in Fig. 1). In a modification, switches for de-energizing the electromagnet are arranged at a vehicle clutch and/or brake pedal. In a further modification an electric motor drives an hydraulic pump which in turn drives the ferromagnetic plate through an hydraulic motor controlled by a three-way valve which may be electromagnetically operated. The plate 12 may be driven by a separate worm and wheel.

Filed: 1969-10-10
Abstract: 1278465 Transistor pulse circuits GENERAL INSTRUMENT CORP 10 Oct 1969 [10 Oct 1968] 49961/69 Heading H3T A circuit, Fig. 2B, receives time-spaced first and second inputs such as # 1 , # 2  (Fig. 1, not shown) and generates at least one further signal # 2  lasting from the start of # 2  to the start of # 1 , the circuit including first switch means such as F.E.T.s Qla, Q2a, Q3a, Q4a receiving both inputs and responsive to # 2  (at Q4a) to connect the output 11a to a negative source (-12 V), and second switch means such as F.E.T. Q5a actuated by # 1  to connect 11a to the positive source (+12 V), the output being maintained at - 12 V during the interval # 2 -# 1  due for example to the charge on Q3a gate capacitance. The clock pulse # 2  turns on Q4a to connect output 11a to - 12 V, and also turns on Q1a to charge Q3a gate capacitance and turn Q3a on. When the # 2  pulse ends, Q4a goes off, but Q3a is held on by charge on its gate capacitance until the 91 pulse appears, whereupon Q2a turns on to discharge Q3a gate and turn it off, and also Q5a turns on to connect the output 11a to + 12 V. A similar circuit to that so far described is used (Fig. 2A, not shown) to generate the complementary output signal #<SP>1</SP>1 lasting from the start of # 1  to the start of # 2 . If an asynchronous clock pulse source is used, wherein the next # 1  pulse occurs at a time after a # 2  pulse greater than the time by which the # 2  pulse follows the # 1  pulse, then to maintain the output line 11a negative for the elongated #<SP>1</SP>2 period despite eventual discharge of Q3a gate capacitance, a large impedance Q6 is connected across Q4a. To counteract the effect of this impedance during the #<SP>1</SP>1 period a further F.E.T. Q7 is turned on by the #<SP>1</SP>1 signal.

The soft polyurethane foam may be formed of two components-(A) an active-hydrogen containing compound component including (a) a primary hydroxyl-terminated polyol, e.g. a polyether polyol having a hydroxyl value, of 30 to 60, (b) a cross-linking agent such as 1,4 butane-diol, glycerine, triethanolamine, or a polyester polyol with a hydroxyl value of 300 to 600, (c) a blowing agent such as water, trichlorofluoromethane or a mixture thereof, and (d) a catalyst such as a tertiary amine or its mixture with a tin compound, e.g. dibutyl tin dilaurate, and (13) an isocyanate component such as crude diphenylmethane-p,p'- diisocyanate. The rigid foam in an example has a polyether polyol component with a higher hydroxyl number than the polyol of the soft foam, with the same isocyanate component as the soft foam, and a silicone oil in addition to catalysts. The tank may have a rustproofing undercoat applied before the foam layers. In Examples, iron plate is coated.

The parison is formed with a thicker wall at the side which becomes the handle. A layer of air is maintained between the parison and the cavity walls during pre-blowing by introducing air through an inlet 72 (Fig. 3, not shown) and bleeding it out through a valve (76). A telescopic core rod 24 is extended during pre-blowing against the urging of spring 88 by air pressure acting on the piston 84 of the end portion 80. Blowing air is supplied through the end portion 80 via tube 86 and check valve 82.
