Patent CA-1249891-A (CA)
Inventor: NORDSIEK KARL-HEINZ
IPC: C08L27/00

Granted: 1989-02-07
Abstract: ABSTRACT         Heat vulcanizable tread strips are produced from novel vulcanizable compositions.  The tread strips are useful for the pro-duction of treads of pneumatic motor vehicle tires. The vulcanizable compositions are based on a rubber component which includes a special rubber component based on 1.3-butadiene and isoprene.          The special rubber component has specific properties.         The tire treads have an excellent combination of use-ful properties which can be described by the following set of characteristics: a) High flexibility at low temperatures, i.e., the elastic rubber state is retained even at temperatures below -30°C          (i.e., good cold-weather properties); b) High vibration-damping over a wide temperature range, and thus good wet skid resistance (i.e., tread safety); c) High wear-resistance, and thus long service life (i.e., economic advantages).         The tire treads have good all-weather characteristics, and thus the tires may be used year-round.

Abstract: METHOD AND APPARATUS FOR FEEDING A PLASTIC RIBBON             ABSTRACT OF THE DISCLOSURE:          A method of and apparatus for feeding a continuous thin film plastic tape or like, pliable, foldable strip in an oscillatory fashion, which may be random, from a feed surface having a width many times greater than the width of said tape to a receiving surface having a width at least as great as a tape width and many times narrower than the width of the feed surface by spacing and positioning the feed and receiving surfaces with respect to one another to limit the maximum angle between a transverse plane bisecting the receiving surface and extending towards the approaching tape and the centerline of the tape.  The maximum value of this angle, in degrees, is about 6.5 times the inverse of the tape width expressed in inches.  The invention is illustrated with an apparatus which converts the oscillatory motion of a tape fed from a roll many times wider than the tape over an equally large roller surface to a pulley only slightly wider than the tape and many times smaller than the roller surface.

Abstract: ABSTRACT OF THE DISCLOSURE            The viscosity of thickened aqueous solutions of water--soluble polymers is reduced by the addition of alkali metal and alkaline earth metal salts of hypochlorous acid and tertiary amines.  The combination of the salt and the tertiary amine is much more efficient in speed of reduction in viscosity and in the completeness of the degradation of the polymer than the use of the metal salt alone.  The process of this invention is particularly useful in fracturing of oil wells.

Abstract: WATER MATTRESS SUPPORT FOR CONVENTIONAL MATTRESSES               ABSTRACT OF THE DISCLOSURE    Conventional bed structures typically utilize a box spring to support the conventional innerspring mattress. This structure is not ideal for supporting the sleeping human body as it tends to produce pressure points on certain parts of the body, and two bodies together on the bed tend to sag to the middle.  Water beds have been developed to provide a more even support, but have not been well adapted to conventional bedding and bedroom furniture. The present invention retains the conventional innerspring mattress and replaces the box spring with one or more water-filled mattresses or bladders to provide more even support, while allowing conventional bedding to be used.

Abstract: Method and apparatus for measuring the strength of a high frequency signal. The strength of a high frequency signal is read-off two or more times at predetermined intervals and the read-off value which is the largest is selected. The selected signal strength is a reasonably precise measurement of the signal strength, as the actual average value for the strength of a signal which is affected by Rayleigh fading is close to the peak value of the signal strength. The method and apparatus according to the invention are particularly suited for use in a scanning receiver in a base station in a cellular radio communication system. The scanning receiver comprises an antenna selector 102 for selection of one sector antenna from among several, a high frequency receiver 104 which can be tuned to several different signal frequencies, an analogue-digital converter 106 which converts the read-off signal strengths to a binary data signal and a microprocessor 114 with peripheral equipment 108, 110, 112, 116, 118, 120 for controlling the operation of the antenna selector 102, the receiver 104 and the analogue-digital converter. <IMAGE>
