Abstract: Thermoplastic elastomers with good mechanical properties are prepared by mixing a rubbery ethylen polymer and a crystalline polyolefin. The rubbery ethylene copolymer is converted to this end with an unsaturated carboxylic acid so that the gel content in benzene is in excess of 50% by weight. At these gel contents good mechanical properties and a good processability are obtained, provided that a limited, preferably deficient, amount of crystalline polyolefin is present. 
     The mixtures are particularly suitable for applications in which high demands are made on mechanical properties at both high and low temperatures, for instance in the automotive industry.

Abstract: In this monitoring device, a light transmitter (4) and a light receiver (5) are arranged on one side of the transport channel (1) and a reflector is arranged on the opposite side. Reflective light barriers of this type are used in printers for determining operating states of the printer as a function of the recording medium, for example for the arrival time of the recording medium, its passage or local positions inside the transport channel (1). In order to avoid difficulties during the adjustment of the sensor (3), which consists of the light transmitter (4) and the light receiver (5), that is to say to avoid reflections and thus false signals in the light receiver (5) in the case of reflective or largely white recording media (2), it is envisaged to provide two reflectors (7b, 7c) arranged with the same spacing from the light transmitter (4) and the light receiver (5) and lying opposite the reflector side (7a), and to connect a screen (9a or 9b) in the beam path (8) upstream or downstream of the light receiver (5) and/or the light transmitter (4). <IMAGE>

Patent EP-0063810-A1 (EP)
Inventor: GORDON JULIAN DR
IPC: G01N33/543
Filed: 1982-04-26
Abstract: The invention relates to new devices and kits for immuno-assays, especially solid-phase immuno-assays, comprising a solid porous support, preferably in the form of a sheet, where antigens or immunoglobulins, or both of them, are bound by direct application, with no other chemical or electrochemical treatment. The use of such supports makes possible to effect an unlimited number of antibody-antigen reactions simultaneously and in one operation. The assays with these new kits are technically extremely simple in practice. The antigens or immunoglobulins on the solid support can be applied in any suitable pre-selected geometry, e.g. as an array of dots, preferably micro-dots, or lines. A preferred material for the solid support is nitrocellulose or nitrocellulose mixed with other cellulose esters. 
     Before carrying out the immuno-assays residual adsorbing sites on the support must be saturated with whole serum of heterologous species to prevent non- specific binding. The invention is also directed in particular to devices and kits treated in this manner, and. if desired, washed and dried. They can be stored for an indefinite time without loss of activity. 
     In the immuno-assays to be carried out according to the present-invention the preferred detection system is the use of anti-primary species antibody coupled to peroxidase with a chromogenic substrate. The color intensity can be quantitated and calibrated with standards of known amounts of immunoglobulins bound to the same support. Densitometry permits the evaluation of the color reaction over a 1000-fold range of concentrations. 
     The new kits can also be used with specific anti- bodies in a pre-determined array on the solid support for the detection of specific antigens and with complement proteins to detect antigen-antibody complexes.

Abstract: The free fluoride content of the aqueous acidic solution is recorded e.g. by an electrode 2 and a signal is generated, in response to the deviation of the actual value from a predetermined value, and this signal is utilised for controlling a pump 14 for supplying replenishment. Acidity is measured by an acidic conductivity device 17 which generates a signal for controlling a pump 19 by which acid replenishment may be added through 21 or in another embodiment the operation of the pump 19 is in a predetermined fixed relationship to the operation of the pump 14. A timer 23 is provided for starting each replenishment cycle. The temperature of the solution may be recorded by a sensor 13 and the said predetermined desired value of free fluoride may be varied automatically in response to and to compensate for the deviation of the actual temperature from a predetermined temperature. Measurement of acidity by pH is said to give unsatisfactory results.
