Patent EP-0027480-A1 (EP)
Inventor: KELLY WILLIAM GEORGE FRANCIS
IPC: B29C48/08
Filed: 1979-10-22
Abstract: A process for producing thermoplastic rubber products whereby thermoplastic rubber containing minor amounts of amorphous polypropylene is extruded into films, which can be formed into other products such as reticulated film. The films and products formed therefrom retain characteristic elastomeric properties of pure rubber, but are significanly more processable owing to the presence of the amorphous polypropylene.

Abstract: The invention relates to an agricultural pesticide including as its chief material lime saccharate obtained by bonding lime and saccnarose, and further relates to a method of preparing such pesticide. A bordeaux solution obtained by mixing and reacting the agricultural pesticide of the invention with an aqueous solution of copper sulphate gives a clear, blue soiution wnich, upon being spread over agricultural crops, dces not remain as residue and undergoes a reduction in toxicity. It is also possible to simplify the adjustment and preparation of the bordeaux solution. In addition, a mixture of the lime saccnarate (strongly alkaline) with an aqueous solution of an acidic agent for spreading over crops can be used as an agent for adjusting pH in agriculture. Moreover, an aqueous solution of the water-soluble iime saccharate is effective for use as a calcium replenisher to be applied to the leaves of crops.

Abstract: Transducer head to data track alignment is corrected in a helical scan rotating head magnetic tape unit by displacing the head in a direction perpendicular to the direction of rotation of the head underthe control of an error signal indicative of misalignment between the head and a desired data track. The error signal is generated in responsetothe sensing bythe head of a longitudinal servo track record defining the locations of oblique data tracks. Displacement of the head is effected by mounting the head on a piezoelectric actuator controlled by the error signal. 
     By successively sensing a series of longitudinal servo track records on the tape, alignment of the head with an oblique data track is repeatedly corrected as the head scans the data track In this manner the head is caused to follow a skewed c deformed data track.

Abstract: A transmitter (11) is coupled via a transmission or storage medium (5) to a receiver (19). The transmitter encodes a sequence of source symbols k in accordance with an arithmetic coding technique, whereby roughly, digital numbers representing the successive source symbols are successively added at the low order end of the previously developed sum to develop a data string. The possibility of rippling of carries to the higher orders of the data string, which would prevent any part of the data string from being transferred until all the source symbols had been received, is prevented by the insertion of a control character in the data string, where n consecutive characters of the same kind occur. The data string can thus be transferred in high to low order sequence, in sections before the data string has been completely formed. The receiver decodes the data string by correcting appropriately for the control characters.

Abstract: A combustion analyzer, for example for the analysis of the carbon and sulphur content in steel, includes a gas flow system whereby a carrier gas flows through a combustion chamber (36) and gaseous products of combustion flow through one or more infrared cells (54, 60) for analysis. A method is described for the correction of the inherent non- linearity of the measurement of concentration by the infrared cell or cells, and apparatus for performing the method is also described. Discrete levels of concentration of known gases are dosed into the system through flow resistors (83, 85) at varying pressures set by a pressure regulator (70) and the detected concentration measured by the infrared cells. Scaling factors are determined by an iterative process employing a microprocessor which scaling factors are then employed to correct for the nonlinearity in sample measurements. The flow resistors and operating valves are mounted on a manifold having short passages to maximise sensitivity.

Abstract: Waste material is sucked away from different suction points (1-8) and is transported in branch conduits (12) to the common collecting point comprising a container (9). The dimensions of the branch conduits (12) and the collecting container (9) are thus chosen that the air velocity in the conduits (12) is sufficient, but in the container (9) insufficient to carry the waste material in the air stream. This will cause the waste material to be extracted in the container (9) and collected in the bottom thereof. The air stream is then passed through a filter (10) before it is returned to the interior space of the building. In the upper portion of the collecting container there are separate openings (11) for the branch conduits (12) connected to the container (9). The lower portion of the container is formed with a funnel-shaped bottom for convenient collection of the waste material. The air flow through the openings (11) in the container (9) or in the branch conduits (12) are controllable by means of individually operated valves (20).

Abstract: A vehicle detector installation comprises a loop oscillator (10) the loop (12) of which is laid in the roadway and which is locked in operation to a voltage controlled oscillator (VCO) (112). Vehicle detection is effected by a phase detector (16) monitoring the phase difference between the oscillators. The VCO is incorporated in a phase-lock loop (PLL) (110) that is capable of locking to a multiple of a reference frequency (f r ) oscillator over a range of multiples. To achieve the locking of the loop oscillator to the VCO means (130) are provided for disabling the normal operation of the PLL and sweeping the VCO over its range of frequency until the phase detector indicates that the loop oscillator and VCO frequencies are equal. This indication activates the PLL to its normal operation to pull the VCO and therewith the loop oscillator to an adjacent multiple of the reference frequency. The PLL is maintained by a repeated charge/discharge cycle of the VCO capacitor (C1) that is dependent on the phase of the reference oscillator and the VCO.
