Abstract: A strapping tool having a resiliently biased feed wheel and a gripper plug in the base thereof. The feed wheel is movable relative to the gripper plug to permit loading and releasing of overlapping loop strap ends therebetween. The gripper plug has a concave gripping surface and is pivotally mounted in the base of the tensioning tool with the pivotal axis parallel to the axis of the feed wheel, thus permitting rotation of the gripper plug about its pivotal axis under the influence of the force on the overlapped strap ends during the tensioning action by the feed wheel. The interaction between the feed wheel surface and the concave gripping surface of the gripper plug distributes the impressed force therebetween uniformly over the segment of the overlapping strap ends lying between the two surfaces to preclude pinching of the strap.

Abstract: An oil burner unit comprises an oil pump and a fan which are both driven by the same motor. The pump (3) is of the kind which begins to operate only above a predetermined critical speed. When starting the unit, the motor is first energised by a first current supply circuit having an impedence (6) and thus operated at a reduced number of revolutions at which the pump (3) is out of operation but the fan (2) is working to ventilate the combustion chamber. After the lapse of a predetermined period of time the number of revolutions is increased to cause the pump to operate, whereby the combustion can begin. The changeover is achieved by means of a time delay device which closes a second circuit to increase the motor speed and thereby cause the pump to deliver oil.

Abstract: The invention is applicable in the sphere of the preparation of printing blocks or forms by means of electronic color scanners. The recording of line elements (lettering, signals, edge spike, etc.) by such scanners is concomitantly performed by selective energization of separate recording beams with greater line resolution than half-tone recording. Without losing time during recording, a stair-shaped distortion of smooth line contours is reduced in such degree that it no longer makes itself felt in troublesome manner in practice.

Abstract: An inverter system including a controlled direct current (d.c.) power source for providing a variable d.c. voltage to a variable output frequency inverter circuit by way of a suitable d.c. link, includes suitable circuitry for detecting a commutation fault or shoot-through condition within the inverter circuit and for taking appropriate remedial action to correct such condition. The shoot-through condition is determined as a function of the d.c. input current to the inverter circuit, the output alternating current (a.c.) of the inverter circuit and the extant condition of the load. In the particular embodiment of the invention illustrated, the load is an a.c. motor and the load condition sensed is whether the motor is in the running or idle mode of operation.

Abstract: The invention relates to a breathing apparatus with a semi-closed circulation for divers. This breathing apparatus has devices for reducing the quantity of breathable gas fed to the breathing cycle, which devices respond to the external pressure to which the diver is exposed. In the case of increasing diving depth and the thus increasing pressure, the quantity of breathable gas flowing into the breathing cycle of the apparatus can be reduced by these devices, the partial pressure of the oxygen in the breathing cycle being maintainable between given pressure limits in the case of maximum or minimum consumption of oxygen. The breathing apparatus has gas passage apertures which are dimensioned such that they cannot be blocked by particles of dust or ice. The gas passage to the breathing apparatus can also be reduced in the case of continuing operating pressure, the gas exerting this operating pressure constantly flowing out into the breathing cycle and the devices for reducing the quantity of breathable gas opening when the operating pressure drops. As a result, the breathing apparatus remains operationally safe.

The multiplex signal comprises: an audio-frequency first information signal and, in the case of a stereo transmission, a second information signal modulated on a suppressed stereo subcarrier, a stereo pilot signal whose frequency (fp) is situated between the frequency spectra of the two information signals, a first binary-code signal (fp-fc) which is phase-modulated on a first code subcarrier situated outside the frequency spectra, which code subcarrier is a harmonic of a subharmonic of the stereo pilot (fp) which harmonic does not coincide with a harmonic of said pilot (fp), the multiplex signal, in order to extend the transmission capacity, comprising a second binary-code signal which is phase-modulated on a second code subcarrier (fp+fc). The carrier wave information of the two code subcarrier waves can be identified in a simple way by selecting their frequencies to be symmetrical about the stereo pilot signal or its harmonic (3fp) and by selecting the phase angle between the sum of the two code subcarriers and the stereo pilot or the relevant harmonic thereof to be situated at preferably an integral multiple of  pi /4.

Abstract: The unauthorized reading of program words stored in a memory of a dating processing system is counteracted by supplying the unauthorized reader with nuisance data from a data source instead of program words from the memory. In order to determine whether the memory is being read by an unauthorized reader or by a data processor unit of the system for the execution of the program, use is made of the sequence in which the data processor unit reads the program words from the memory. This sequence deviates from the sequence in which the program words are stored in the memory. Additional information is added to each program word stored in the memory, said additional information containing an indication of a subsequent program word to be read by the data processor unit. On the basis of this additional information it is tested whether the memory is being read in the sequence determined by the data processor, for the execution of the program, or in some other sequence by an unauthorized reader who does not know the sequence determined by the data processor unit.

Abstract: The invention relates to an arrangement in an infrared analyzer for determining the proportion of a given substance or substances in a powderous material, such as flour. When making an analysis, the infrared analyzer irradiates the material with infrared light and detects light reflected from the material through a window in the wall of a conduit, in which the material is passed in a direction substantially parallel with the window. During the analysis, the material is held stationary, and compacted in the conduit. The conduit has arranged therein a feed screw having a controllable drive-means in a material-infeed end, and extends horizontally or slopes upwardly from the aforementioned infeed end. A control means steers the drive means and the analyzer cyclically in a manner such that during a first time interval the drive means is activated and the analyzer inactivated, and that during a second time period the analyzer is activated and the drive means inactivated.
