This invention relates to a movement monitor (16) that is suitable for detecting movement, and also provides an alarm (18) should movement that is being monitored cease. The movement monitor is particularly suitable for use with humans or other living organisms where breathing movement is being monitored. In considering the use of the movement monitor on human infants, it is particularly useful fo...

Adducts of tetrasubstituted pyrophosphato titanates and/or amines, having the formula XcTi[OP(O)(OR1)OP(O)(OR2)OR3)]4-c (NR4R5R6)d[P(OR7)(OR8)(OR9)]e, are useful in improving the physical and chemical properties of many filled resins.

The title compds. (I)[R1, R2=-X-COOR3 or -Y-CN; X=C1-6 alkylene; R3=C1-8 alkyl, C3-6 cycloalkyl; Y=C1-6 alkylene are prepd. as insecticide. Thus, 1.6 g pyridine was added to 2.1 g sulfur dichloride dissolved in 35 ml CCl4 at 0-5↿C. The resulting mixt. is mixed with 3.8 g ethyl imino-diacetate at 10-20↿C to give 5.0 g bis (ethoxy-carbonylmethyl) aminosulfenyl chloride.

The combination has a sharp-edged tool (14) having a handle portion and a cutting edge for cutting or marking a workpiece (15a). The handle is provided with mechanical means for securing the tool to the outer end of a metal band (11) belonging to said measuring tool (10).

A plate-shaped sign (1) for identification purposes, said sign being adapted to be placed around an edged object by bending the sign around the edges of the object. To prevent possible theft, the plate (1) has at least one bend which is resistant to backward bending about an associated bending line (4, 5), and the plate is moreover capable of being bent via weakening along other bending lines (2, ...

In a high-power transmitter with automatic controlling and monitoring, the data and instructions are exchanged between the contact points (34, 35, 36) and measurement points (101 ... 10n) and the transmitter controller (19) via a common serial data and address bus (21), the exchange of data and instructions being controlled by a central processing unit (22). The bus structure leads to simplified c...

Synthetic rubber is thermooxidatively stabilized with guayule resin. The guayule resin imparts favorable stabilization as evidenced by minimum bulk viscosity changes and minimum gel formation, especially with styrene-butadiene synthetic elastomers prepared by emulsion or hydrocarbon solvent techniques.

When charging accumulators (1) with a constant charging current intensity, the problem arises that, if it is only slightly discharged, the accumulator (1) can be overcharged such that its life is reduced, or, after a previously heavy discharge, is fully charged again much too late, since the charging current is too small. The charging current is therefore regulated as a function of the charge or d...

The combined production of ammonia and urea by the reaction of gases containing hydrocarbons with steam is conducted by using a steam reformer, downstream secondary reformer, and shift converter. The ammonia synthesis gas (hydrogen, nitrogen and carbon dioxide) is subjected to a high pressure scrubbing step with a physical solvent, to remove the acid impurities, especially CO2. The pressure on the...
