Abstract: The object of the invention is a so-called applicator for microwaves 2.45 GHz, to be used in pre-drilled holes in e.g. masonry in order to heat and subsequently dehumidify it. 
<??>The applicator has several radiating areas in the axial direction, eliminating uneven heating which would otherwise result due to the limited microwave energy penetration depth. Furthermore, radiation may be directed in varying angular directions, so that while several parallel holes are being treated simultaneously , drying proceeds preferably in left-right directions thereby improving efficiency. The asymmetrical radiation pattern is emitted from openings in the outer conductor of a coaxial line. In the openings at least one section plane varies in its axial position in relation to the angular coordinate.

Abstract: The method according to the invention is proposed for the operating of compression-absorption heat pumps or refrigeration machines (of hybrid heat pumps and refrigeration machines), using a working medium consisting of two media of different volatility but which dissolve well one in the other. In the method, when heat is extracted during a first heat exchange operation, on the one hand the vapour of the more volatile component (component with lower boiling point) is dissolved in the liquid of the less volatile component (component with higher boiling point) (absorption), on the other hand the vapour of the less volatile component is condensed (condensation), then, after expansion of the working medium, when heat is supplied during a second heat exchange operation, on the one hand the more volatile component is at least partially driven out of the solution (degassing), on the other hand the less volatile component is at least partially evaporated (evaporation), after which the working medium is compressed. 
<??>The novelty of the method according to the invention is that the working medium is derived from the first heat exchange operation as a mixture of two different phases (liquid and vapour) of different concentration. 
<??>The heat pump or refrigeration machine suitable for realising the method according to the invention includes, in series connection in the direction of flow of the working medium, a condenser-absorber (1), a liquid-cooling inner heat exchanger (5), a pressure reducer (2), an evaporator-degasser (3) and a pressure increaser (compressor) (4), the output of the latter being connected to the input of the condenser-absorber (1). 
<??>The novelty of the device is that a vapour-cooling inner heat exchanger (6) is interposed between the condenser-absorber (1) and the liquid-cooling inner heat exchanger (5).

Abstract: A non-circularly-symmetric intensity distribution is formed on a quadrant photodetector by coherently mixing two optical signals propagating in selected modes of different order. These modes are chosen either such that a change in relative phase of the two signals produces solely a rotation of the orientation of that intensity distribution, or such that a change in relative states of polarisation produces this rotation.

Abstract: In the incubator, which is formed from a housing (21) providing useful space and a door (20) enclosing the latter, all the functional and operating elements are accommodated in the door (20). As a result, the housing (21) providing useful space can, in the ideal case, be produced from a single cohesive plastic or ceramic housing part (11), as a result of which the number of structural groups and hence the production costs can be greatly reduced. The incubator can be closed in a completely gas-tight manner, and has low thermal inertia and excellent heat-insulating properties. The arrangement of the functional elements in the door (20) results in very easy maintenance. <IMAGE>

Abstract: Neutral amino acids can be recovered from an aqueous solution by the steps of:
     1) forming a concentrated solution of said amino acid which solution has a pH above the solution pKa of the acid   2) removing base uniformly from the solution so as to form solid particles of the neutral amino acid at a pH above the solution pKa of the neutral amino acid.   3) recovering said solid particles from the solution.    This method provides a product that is highly pure without the need for organic solvents. In a preferred embodiment, the solution is first concentrated and then filtered at high pH. This high pH filtration avoids the need for conventional ion exchange treatments.

Abstract: Apparatus determining capacitive and resistive values of an electrical component, such as a fuel level determining probe (14), includes a waveform generator (10) for subjecting the probe to a time-varying waveform which includes a linearly varying ramp portion and a fixed, constant portion. A selectively controlled sample and hold circuit (20) senses the voltage potential of the probe in response to a zero crossing detector (32) during the linearly varying ramp portion of the waveform to provide information indicative of the capacitive value and again senses the voltage potential at selected time thereafter during the fixed portion of the waveform to provide resistive value information. The output of the sample and hold circuit (20) is fed to an analog-to-digital converter (22) which provided digital information to a stored-program controlled processor (26) which in turn provides the desired output information. A calibration standard (16) may be periodically switched into the circuit to provide reference values for comparison against the measured values.

Abstract: A regulator for adjusting the amount of power generated by a pneumatic fastener driving tool (1) of the type having a body (2) connected to a source of air under pressure and containing a cylinder (46) with a piston/driver assembly (48, 49) mounted therein and a main valve (58). The main valve is slidably supported above the cylinder on a centerpost (53) affixed to a cap (52) closing the top of that portion of the tool body surrounding the cylinder. The main valve is shiftable on the centerpost between a closed position engaging the upper end of the cylinder and shutting off the cylinder from the supply of air under pressure within the tool body and opening vent passages (92) in the centerpost and cap to vent the cylinder volume above the piston to atmosphere, and an open position closing the vent passages and opening the upper end of the cylinder to air under pressure within the tool body to actuate the tool. The regulator comprises an adjustable stop (54) mounted in the centerpost and extending thereabout. The stop is shiftable toward and away from the cylinder and determines the open position of the main valve and thus the size of the opening between the cylinder and the main valve, which determines the power generated by the tool. An adjustment screw (61) is rotatively mounted in the cap, having a first end above the cap and provided with a knob (62) and a second end (134) threadedly engaged in the stop to shift the stop.

Abstract: A multiplex transmission system, in which a node as a transmission node transmits data frame by frame to a transmission path, and a plurality of other nodes, as reception nodes, returns a reception acknowledgment signal to the transmission path upon proper reception of the frame of data. Each of the reception nodes which properly received the frame returns the reception acknowledgment signal specific thereto to that division of a reception acknowledgment signal area in the frame which corresponds to this node. Each node discriminates the success/failure of signal transmission, by comparing the information registered beforehand in its reception acknowledgment signal table with the information in the reception acknowledgment signal area. When the information of the reception acknowledgment signal table does not coincide with that of the reception acknowledgment signal area, the transmission node re-transmits the frame and the reception acknowledgment signal tables of all the nodes are updated. The system can not only effect the addition and deletion of multiplex nodes easily without requiring the change of scale of the circuit of the system, but also discriminate trouble for each of the multiplex nodes.
