Abstract: Abstract An apparatus for detecting a temperature by means of at least one temmerature-responsive sensing resistor (F1,F2) comprise  an evaluating circuit which processes a voltage drop depending on the temperature of the sensing resistor.  The sensing resistor (F1,F2) lies at a common current source (1) in series with two fixed calibration resistors (G, D).  The basic resistor (G) has a lower calibration value (Rel) which is assumed by the sensing resistor at a predetermined lower temperature.  The differential resistor (D) has a differential calibration value (Rd) of such a size that the series circuit of the calibration resistors has an upper calibration value (Re2) which the sensing resistor assume at a predetermined higher temperature.  The evaluating circuit determines the actual temperature from at least one measurement voltage drop (Vfl, Vf2) with regard to a characteristic calibration curve resulting from at least one calibration value (Rel, Re2, Rd) and the associated calibration voltage drop (Vel, Ve2, Vd).  This leads to a very simply constructed apparatus which is easily adjustable.            Fig. 1.

Abstract: ABSTRACT "Device for correcting and concealing errors in a data stream, and video and/or audio reproduction apparatus comprising such a device."     A device is described for correcting and concealing errors in a data stream which is block-wise provided with redundancy. The redundancy has an error-correction capability per block. The blocks are received from a medium in a systematically distributed manner. After regrouping, error-signalling is formed per block by way of the error-correction code. For a number of successive blocks the total number of expected errors is compared with a threshold which lies within the error-correction capability of the code. When this threshold is exceeded, concealing takes place, even when the total maximum correction capability of the code has not yet been fully utilized.

Abstract: APPARATUS FOR STAKING       Abstract An apparatus for staking a formable projection, for example, a tab or boss, to retain plural articles in a unitary assembly.  A projection on a first article is brought into registering position with an aperture in a second article to form the assembly.  The assembly is clamped by a spring-loaded clamp pad which bears against the second article and surrounds the projection.  The projection is then staked by action of a tool which travels reciprocally within the clamp pad and has a tip which cooperates with the clamp pad to form a cavity of desired shape.  The forming stroke of the tool is against the resistive force of the spring, which increases the clamping force of the clamp pad.  The formed projection is therefore contained within the inner boundary of the clamp pad and tool tip to thereby promote uniform head formation.

Abstract: ABSTRACT         A mobile communications apparatus is disclosed.  It includes a load circuit to which a DC voltage is supplied from a DC power source.  A reset voltage detector generates a reset signal for turning off the load circuit when the DC voltage falls below a predetermined level and a reset release signal turns on the load circuit when the DC voltage returns to or above the pre-determined level.  Also included is circuitry for detecting whether or not a change in the DC voltage is an instantaneous drop, circuitry for measuring the lapse of time from the actuation of the load circuit till the generation of the reset signal and cir-cuitry for comparing, when the instantaneous drop detector means has determined the change to be an instantaneous drop, the measured lapse of time with a predetermined length of time.  If the measured time is longer than the predetermined time, the actuated state of the load circuit is retained, but if the reverse is true the load circuit is turned off.  The apparatus can operate even when the DC power source, usually a battery, has deteriorated.

Once burning has been initiated at the burner nozzle,  air is sucked into the venturi passage mixed with gas and flows through the burner tube to the burner nozzle for ignition by burning gas from the retention line.

In prior art processes significant amounts of the diisopropyl compound were produced; this was economically undersirable. This process gives increased yields the required product and is therefore more economically viable. About 10-30 mole % (based on pseuodocumene) of (I) are used. In the first stage of the reaction excess propene and pseudocumene are reacted to produce 1,2-4-trimethyl-5-isopropylbenzene and trimethyldiisopropylbenzenes, the two are separated and the diisopropylbenzenes introduced into a further alkylation.
