Title: Ignition Timing Control System for Internal Combustion Engine
IPC: F02P5/153
Filed: 1980-05-14
Abstract: In such a system, an acceleration sensor 10 senses mechanical noise components and knocking signals originating from an internal combustion engine. A frequency filter 12 attenuates the mechanical noise components and supplies the sensor signal including any knock signals, ignition noise and attenuated mechanical noise to an analog gate 14. The gate 14 is closed for a period after each ignition instant by a gate timing controller 16 to remove ignition noise. The output from the analog gate 14 is applied to a noise level detector 18 and a comparator 20 compares the noise attenuated sensor signal with a D.C. voltage delivered by the detector 18 to eliminate the noise and form knock pulses which are then integrated and used to control the timing of an ignition signal applied from a generator 26 to an ignition coil 32, whereby the ignition timing is retarded so that the knocking is eliminated. <IMAGE>

Patent GB-813311-A (GB)
IPC: B29C44/12
Abstract: 813,311. Foamed polyurethane. AGRICOLA REG. TRUST. June 29, 1956 [July 6, 1955; Aug. 23, 1955], Nos. 19546/55 and 24257/55. Class 2 (5). [Also in Group VIII] An expanded plastic (e.g. foamed polyurethane) incorporates a net or other fabric of net-like structure which is extensible in all directions and which allows an initial freedom of movement and thereafter inhibits further stretch and consequent tearing of the plastic. The net may be embedded in the plastic, or as shown (Fig. 1) may be secured to the surface of the plastic 2 or may be enclosed between two sheets 4 and 5 of plastic. The net may be secured by means of an adhesive, e.g. a polyurethane foam adhesive, or by melting the surface of the plastic by radiant heating and then applying the net, or by incorporation in the plastic during manufacture. Where the net is used on the surface of the plastic, the plastic may be caused to bulge through the apertures in the fabric. If the net has square apertures, as shown in Fig. 1, the threads must have a limited elasticity or must be puckered during insertion by stretching the plastic before applying the net, and releasing it after that application. The net may have apertures of other shapes (e.g. hexagonal) and may be a knotted net, a twisted net or a lace net. A number of spaced layers of net may be embedded in a block of plastic, which may be subsequently split between these layers to produce thinner reinforced sheets. In a modification (Fig. 5) the net or fabric is replaced by co-operating layers of parallel threads positioned at an angle to one another in parallel planes. The layers of threads may be in contact as shown, or may be separated by a layer of expanded plastic. The threads themselves may have limited elasticity or the layers may be stretched to the desired limited extent before the threads are attached and then released so that the threads pucker. The two layers may be attached to one another when relaxed or when stretched.

Title: Growth of structures based on group iv semiconductor materials
Inventor: LEAMY HARRY JOHN
IPC: C30B1/00
Filed: 1982-01-21
Abstract: Single crystal layers of Group IV semiconductor materials, such as silicon, are grown on insulating substrates. The fabrication of this structure is achieved by forming on a single crystal substrate a layer of an insulating material (e.g. 41), such as a silicon oxide. A small via hole is produced in the insulating layer to leave a portion of the underlying substrate uncovered. A precursor material (e.g. 52, 62, 72) is deposited on the insulating layer so that it covers at least a portion of the insulating layer and also contacts the substrate at the via hole. The precursor layer is then formed into a single crystal (e.g. 74) by inducing growth on the substrate at the via hole and propagating this growth through the precursor layer.

Title: Sludge treatment or dewatering process
Inventor: PREJEAN JAMES A
IPC: C02F1/52
Filed: 1982-10-06
Abstract: Solids and liquids contained in an aqueous dispersion, which may also be oil-bearing, are separated by adding a flocculating agent to the dispersion while flowing through a pipe, and then subjecting the flowing aqueous dispersion to a flow restriction to mix the flocculating agent and to flocculate the solids. The thus treated dispersion is discharged onto a surface permitting free liquid run-off and deposition of the floc. The process is particularly applicable to oil-bearing waste water sludges and waste oil sludges and facilitates recovery of the oil and land forming of the solids.
