Abstract: A metal vapour discharge lamp, a starter connected in parallel a discharge tube (11), combines a coiled non-fusible metal wire (12) which is wound on or laid along the outer wall of the discharge tube (11) and a non-linear capacitor (15) which is series connected to the non-fusible metal wire (12). 
     As a result the discharge lamp can be assuredly and stably lit wth a small size ballast. Furthermore, passage of large current through the starter can be prevented even if the incandescent tube leaks. Furthermore, if the evacuated outer envelope (16) leaks or is broken, the circuit of the starter can be opened in that the non-fusible metal wire (12), which is heated by the discharge tube (11) oxidises and thereby becomes incandescent and breaks.

Abstract: The invention relates to a device for joining metal sheets together, comprising a punch and a die with elastically deflectable cutting parts. The dimensions of the punch, on the one hand, and of a closed contour of the die, on the other hand, define a joining region, such that none of the sheets is cut through and the joint has essentially isotropic tensile strength in all directions parallel to the sheets. The joint is also aesthetically pleasing on both sides.

Abstract: In the case of known overload safety arrangements for centrifugal pumps, temperature sensors, which are immersed directly into the liquid medium conveyed by the pump, are used to measure the temperature. Should the temperature measured by the temperature sensors deviate from a predetermined temperature reference value, an outlet valve is opened via an adjusting device and/or an acoustic or visual signal is triggered or the pump drive is switched off. In so doing the danger exists, particularly when conveying liquids containing chemically aggressive substances and/or abrasive solids, that the temperature sensors will be very quickly destroyed and therefore fail as measuring instruments to detect the operating temperature. These overload safety arrangements are also relatively complex in their design. According to the invention, on the other hand, an overload safety arrangement for centrifugal pumps, which is of particularly simple design and always functions, is achieved in that the outlet valve (11) and the temperature sensors (2, 3) are arranged in the wall (1) of the spiral housing, the temperature sensors (2, 3) being arranged in the body of the wall (1) of the spiral housing at a distance (d) from the inner wall surface (18). <IMAGE>

Abstract: A transient voltage difference circuit is coupled into a TTL current sinking output circuit for transient performance enhancement during transition from high to low level potential at the output. The TTl output circuit includes a pulldown transistor element (Q₅) for sinking current from an output node to low potential, a base drive transistor (Q₄) for driving the base of a current sinking pulldown transistor element (Q₅), an input base node (A) of the base drive transistor (Q₄) coupled to receive input signals of high and low level potential, and a voltage clamp network (Q₁,Q₂,Q₃) coupled between the input base node and low potential for maintaining a potential level at the input base node sufficient to turn on the base drive transistor. An RC network (R₄,Q₆) is coupled between the input base node (A) and low potential. The resistance (R₄) of the RC network is coupled in series with the voltage clamping network (Q₁,Q₂,Q₃) adding a transient overdrive voltage in series with the clamping voltage at the input base node when the capacitance (R₅) of the RC network  (R₄,Q₆) is charging through the resistance (R₄) during transition from low to high level potential at the input. The RC network (R₄,Q₆) and the voltage clamp network (Q₁,Q₂,Q₃) effectively form a Y network with the common branch coupled to the input base node through the resistance (R₄).

Abstract: The invention relates to a stirring and/or kneading machine (1) with at least one stirring and/or kneading tool (6) which rotates about its own axis and has an undivided tool shaft (18) passing through, the product zone (3) being sealed from the drive zone (2) of the stirring and/or kneading machine (1) in the region of the tool shaft (18) by a seal (19) applying to the tool shaft (18). The invention here provides that the tool shaft (18) is held secure against rotation and releasable in a rotatably mounted hollow shaft (20), that all the drive wheels and/or driven wheels (13, 16, 17) provided for the shaft (18) and all bearings (21) bear against the hollow shaft (20), and that the hollow shaft (20) ends on its side pointing to the product zone (3) in front of the shaft seal (19) which separates the drive zone (2) from the product zone (3). Inspite of the undivided tool shaft (18) going through, the gear (7) provided for the shaft drive does not have to be completely removed and dismantled when, for example, the shaft seal (19) or any blades (4) which may be solidly welded to the tool (6) must be replaced. Rather, in the kneading machine (1) according to the invention, the tool shaft (18) can be removed from its hollow shaft (20) and re-installed quickly, conveniently and by simple means. This allows shorter stoppage times. <IMAGE>

Abstract: Combination of photosensitive elements for use in radiography consisting of a pair of radiographic fluores­cent screens and a double-side coated silver halide ra­diographic element. Each screen is arranged adjacent to each silver halide layer and each screen is capable of imagewise emitting radiation to which the adjacent silver halide layer is sensitive when imagewise exposed to X radiation. The combination is characterized in that one fluorescent screen emits a first radiation in a first wavelength region of the electromagnetic spectrum and the other fluorescent screen emits a second radiation in a second wavelength region of the electromagnetic spectrum, and each silver halide layer is substantially insensitive to the radiation emitted by the opposite screen.

Abstract: A semiconductor memory unit suitable to be employed in a microcomputer system includes an address counter for fetching address information from an microcomputer in response to an address latch signal from the microcomputer. 
     The address counter further receives an updating control signal from the microcomputer and updates the fetched address information by one in response to each updating control signal. The memory device further includes a program memory for storing a string of instructions and an address decoder circuit for accessing the program memory in response to the address information from the address counter. Since the address information is updated by the updating control signal, the microcomputer fetches and executes the successive instructions without supplying the respective address information to the memory device.

Abstract: A continuously transmitting and receiving radar comprises a transmitter (10), a receiver (16), an antenna (12) and a circulator (14) for effecting communication between the transmitter and the antenna and between the antenna and the receiver. A reflected power canceller is provided for suppressing the effects of leakage between the transmitter and receiver. The reflected power canceller comprises a directional coupler (20) for supplying a part of the transmitted signal to a modulator (22) which forms a cancelling signal by adjusting the phase and amplitude of the sampled signal. The cancelling signal is applied to another directional coupler (24) which subtracts the cancelling signal from the leakage and wanted signals. A narrowband control path is connected between the output of the receiver (16) and the modulator (22). The reduction in carrier leakage and AM noise sidebands is made more effective by providing a time delay device (21) in the signal path from the coupler (20) to the modulator (22). The time delay introduced by the device (21) is set so that the propagation times between the transmitter (10) and the directional coupler (24) via the circulator (14) and via the modulator (22) are the same. Optionally FM noise can be reduced by ensuring the propagation time of the local oscillator signal applied to a mixer in the receiver (16) is the same as that of the leakage path between the transmitter and receiver. 
     In a non-illustrated radar the circulator (14) may be omitted and separate transmitting and receiving antennas are provided.
