IPC: G09B9/05
Filed: 1964-03-24
Abstract: 1,068,525. Training drivers. GENERAL PRECISION Inc. March 24, 1964, No. 55865/66. Divided out of 1,068,524. Heading B7H. In a driver training apparatus which has a plurality of controls simulating those in a car and a film projecting arrangement for providing a visual display to a trainee, the film used has encoded groups of pulses consisting of serial binary pulse trains recorded upon it at particular film sequences, corresponding to the required operations of the controls by the trainee. As the particular film sequence is projected, the pulse groups are decoded to provide a signal on a given line which operates an error indicator or alarm. Provided that the correct controls have been operated, switches in the given lines are opened to prevent the alarm being operated. The system may be adapted so that a number of trainees may use the same visual display simultaneously. The Specification describes again the analogue simulating circuits for simulating the engine and control functions which are explained in Specification 1,068,524.

Title: Resin-coated rice hulls and the production of composite articles therefrom
IPC: C08L97/02
Filed: 1973-12-04
Abstract: 1403154 Coating rice hulls COR TECH RESEARCH LTD 4 Dec 1973 [14 Dec 1972 (2)] 56028 73 Heading B2E [Also in Divisions B5 and C3] Rice hulls are at least partially coated with a caustic (i.e. alkali) free, thermosetting phenolformaldehyde resin which is of a type that, in its uncured state, has a viscosity of more than 100 Krebb units at 120F. The hulls may initially be cleaned by toppling, grinding or abrading in a fluid stream followed by sieving or air flotation to remove the "fines" or dust. The resin may be applied as a powder or as an emulsion by rubbing on with rollers or by spraying inside a rotating blender provided with baffles, usually at a temperature above 150F. A pH-reducing acid catalyst or chemical that will decompose to yield such acid catalyst may also be sprayed onto the hulls, either before, after or together with the resin. A composition comprising the resin-coated rice hulls optionally together with wood chips and flakes may be fabricated into a composite article, particularly a board, by curing. Layers of the composition may be laid up in a press and cured under heat and pressure to form the board. The hulls in the outer layers of the board may be coated with 10-12% resin while those of the core layer may be coated with only 8-10%, thus providing greater surface hardness, The outer layers may also contain more fines relative to the core and may contain very little or no catalyst while the core contains 5-10% catalyst to ensure uniform cure of the board.

IPC: C01B13/22
Filed: 1965-07-28
Abstract: Finely divided metal or silicon oxides are prepared by the vapour phase hydrolytic reaction of volatile metal or silicon halides in a flame into which the halide is introduced in admixture with oxygen and a gas whose combustion is accompanied by the formation of water, in such proportions that the mixture contains enough oxygen for the complete combustion of the flammable gas whilst the amount of water formed is at least sufficient to hydrolyse the volatile halide, said flame <PICT:1121279/C1/1> burning in an enclosed reaction zone and being surrounded by a gas inert to the reactions in the flame.  In the diagram, the mixture of gases is fed to a burner 11 and the flame 12 burns in a flame tube 13 in an atmosphere of nitrogen supplied by a feed pipe 16 via a gauze 15.  The air may be supplied to the burner in two streams, primary air supplied direct and supporting air bearing the metal halide.

Abstract: 1278610 Cathode-ray tube circuits F F LEE and S K BURNS 22 Dec 1969 [10 Jan 1969] 62397/69 Heading H4T The values of time-varying voltages on a number of channels 0-4 are sampled at intervals, digitized and stored as multiplexed data in delay line memory 7 for read-out and conversion to analog voltages for display on units 40A-40D. The display is continuously corrected to represent for each channel the latest 521 data values and each value is displayed on a separate vertical trace by brightening that trace at a position corresponding to the respective analog voltage. Thus the waveform will move slowly to the left as newly sampled values come to be displayed at the right. Each sampled value is coded as an eight-bit number and each four numbers entered as a 32-bit word into memory 7, the total delay of loop 7, 14 being such that successive words are entered into alternate positions of memory for the first " half-frame " and then interlaced for the second " half-frame ". The line-scan time corresponds to four words and by read-out at fourword intervals the appropriate signals for the interlaced display are obtained, these signals being de-multiplexed at 18A-18D. New sample words overwrite the earliest ones in memory, unless a " freeze " command switches in the further four-word delay 9. If a permanent record of the data displayed on one of the channels is required because of alarm conditions or otherwise this is obtained via 21A and a priority unit 21, or by direct manual keying of 21.
