Inventor: BRENNAN M E
IPC: C08G73/00
Filed: 1976-06-01
Abstract: An improved process for selectively preparing a predominantly noncyclic polyalkylene polyamine compound is disclosed wherein an alkyleneamine compound is contacted with an alkanolamine compound in the presence of a catalytically effective amount of a phosphorus-containing substance at a temperature of from about 250 DEG  to about 350 DEG  C under a pressure sufficient to maintain the mixture essentially in liquid phase and the polyalkylene polyamine is then recovered from the resultant reaction mixture. In a preferred embodiment ethylenediamine is contacted with monoethanolamine to produce a predominantly linear polyethylene polyamine product with very low yields of heterocyclic amine materials. The desired polyethylene polyamines produced can be directly recovered from the reaction products by known purification procedures.

Abstract: The switching system has a chip which is integrated in semiconductor technology and which has an operation register (SR, ZR) which is usable for the mode of operation in the chip and into which register information comprising a plurality of bits is entered which helps to define this mode of operation. The chip which interworks with further chips of the control device is set to the operational characteristics of other chips before the respective commissioning of the system through the input of register information into the operation register (SR, ZR). With the respective commissioning of the control device (ALS) through the application of the operating voltage, register information can be set in the operation register (SR, ZR) which effects a mode of operation in which interworking with chips with different modes of operation is possible. The longest provided work cycle or the most favourable signal level for the transmission of information can thereby be taken into consideration. <IMAGE>

Abstract: Objects are packed in respective receptacles in a unitary body of sheet material having orifices open in a common direction. An annular edge portion of the body envelops the orifices and one or more rib portions of the body separate each orifice from each other orifice. A cover of sheet material is superimposed in a vacuum chamber on the edge portion and the orifices and sealed gastight to the edge portion. When the body with the sealed cover is exposed to atmospheric pressure, the cover is pressed by the air against the rib portions and may be sealed thereto. The sealing die employed in this process need only clamp the edge portion of the sheet material body against a suitable backing die.

Abstract: In the auxiliary response circuit for a relay which is controlled via supply leads (L1/R1, L2/R2) which carry a DC voltage, for example in calling or emergency calling systems, the supply leads, which lead to the ends of the relay winding (W), can be switched over from a polarity which corresponds to the quiescent state into a reverse polarity which corresponds to the operating state of the auxiliary response circuit. A diode (D2, D3) which is reversed in the said quiescent state is in each case connected upstream and downstream of the relay winding. Connected in parallel with one (D2) of these diodes is a capacitor (C) whose electrode which is connected to one of the terminals of the relay winding is connected via a further diode (D1), which is in the forward direction in the quiescent state, to that supply lead which leads to the other terminal of the relay winding. <IMAGE>

Abstract: In a circuit for selectively limiting the rate of change of an interference signal superimposed on a wanted signal, the composite signal Es is fed to a shaping circuit comprising a feedback path which includes an integrator J1 having a variable integration time determined by adder A2, sample and hold circuits S1 and multiplier M1. The resulting signal ???Es is the interference signal and, after having any d.c. component removed by sample and hold circuit S2 and adder A5, has its slope compared with a reference slope in adder A6 to generate a "0" or "1" signal at II depending on whether the rate of change on ???Es is less or greater than the reference slope. The signal controls a changeover circuit M2, M3, A4 so that ???Es is passed to output AS directly if the rate of change low and via a delaying and slope limiting circuit ZV if it is high. <IMAGE>

Abstract: In this system in which the information signals to be transmitted are converted into the digital form, transmission is done via a frequency-division multiplexer which so transmit the bits of the information signals in parallel that the duration of the bits transmitted through the channels of the multiplexer is longer than double the difference in propagation time between two carriers obtained from the two transmitters which are nearest in the receiving zone, where the said carriers have levels which are near to one another. This solves the problem of overlap between the information signals. To control the problem of fading, three types of transmitters which have three carriers whose deviation is very small compared with the bandwith of a channel are used in the transmitter network.

Abstract: A gas detector for detecting a target gas such as hydrogen methane or butane, detects the presence of that gas alone or when in the presence of other gases. The electrical resistance of a main gas sensing element (Sm) responds to both target and non-target gases, and the electrical resistance of an auxiliary gas sensing element (Ss) responds more to non-target gases than target gases. An alarm circuit (AL) is triggered by an alarm signal (Om2) from the main sensing element (Sm) when the gas concentration exceeds a specified level (Vm1), and a second alarm signal (Om3) generated by the auxiliary sensing element (Ss) at a lower level (Vm2) is blocked by detection of a concentration of non-target gas exceeding a specified level (Vs). The sensing elements may be mixtures of metallic oxides, e.g. (1) a mixture of indium oxide, tin oxide or ferric oxide, and palladium oxide which may further contain platinum oxide or rhodium oxide, or (2) a mixture of ZrO2, MgO and Cr2O3. <IMAGE>

Abstract: The invention serves to provide a sensor for measuring the volumetric flow, which can preferably be employed for monitoring automatic, controlled respiration but which is also suitable for recording other, small volumetric flows of gaseous media. In the case of low flow rates the known sensors which operate on the principle of the Karman vortex street are characterised by periodic fluctuations, an inadequate signal-to-noise ratio and an equally unsatisfactory linear relationship between vortex frequency and volumetric flow. It is the aim and object of the invention to eliminate these unfavourable properties, so that there is provided a sensor having a high measuring accuracy for a wide range of flow rates, including the weak movements of gas. This is achieved with a sensor whose measuring section is provided on the inlet side with a parabolic or hyperbolic narrowing which brings about improved formation of vortices of one of its downstream flow bodies having a prismatic cross-section.
