Abstract: Polymerisable dental adhesive cerment with a photoinitiator system containing camphorquinone and phenanthrenequinone have a deep yellow colour which disappears on irradiation with visible light. The yellow colour which is clearly distinguishable from that of tooth substance makes it possible when using a cement of this type to check visually the application or introduction, the removal of excess and the hardening of the cement.

  (a) a light source (14), 
  (b) a multiplicity of light detectors (31-38), which are assigned to one of the panels (21-28) in each case, 
  (c) a light guide (15), which generates from a light bundle (16) generated by the light source (14) a multiplicity of light beams (41-48) which are directed in each case against one of the panels (21-28) and reach the light detectors assigned to them through the transparent panles.

Abstract: In a circuit for operating a discharge pump consisting of a switched-mode power supply with a control circuit, optionally of an inverter and of a starting device, a voltage sensor in the form of an RC network (R1, R3) is connected between the control circuit (ST) and the point (A1) connecting the active semiconductor switch (T1) and the inductance (DR) of the switched-mode power supply. The voltage sensor ensures that the active semiconductor switch (T1) is turned on precisely at the instant when the energy stored in the inductance (DR) has leaked away and the reverse recovery time of the passive semiconductor switch (D1) has expired so that the switched-mode power supply is operated in a "discontinuous mode". <IMAGE>

Abstract: A non-blocking broadband broadcast time-division switching system (10) comprises a time-slot replication stage (12) followed by a conventional TMS stage (11). The replication stage replaces the TSI stage of conventional switching systems. Time division multiplexed links (16) are connected to inputs of the system. Each input link is connected to the input of a different replicator (14). Each replicator has as many outputs as there are time slots (202) in a frame (201) on an input link. Replicators' outputs are connected each to a different input of the TMS stage. In one embodiment, a replicator generates each time slot of a received frame at a different output and replicates the individual time slot at the individual output during each time-slot interval of a frame interval. In another embodiment, a replicator generates each time slot of a received frame at a different time at each output, thus generating a delayed replica of the received frame at the outputs. In either embodiment, during each time-slot interval, each replicator transmits a frame of different received time slots to the TMS stage.

Abstract: A hedge trimming tool having a fixed elongated blade (12) mounted to the power head of the tool and a cutting blade (14) mounted over the fixed blade and reciprocating relative to the fixed blade in the direction of the lengthwise axis. A leading side of the fixed blade has projecting fingers or teeth (30) and the overlying portion of the cutting blade has projecting teeth (32) that reciprocate across the openings between the fingers. The reciprocating teeth have sides configured in a complex curve forming an hour glass planar profile and an inverted U-shaped cross section. The U-shaped cross section is provided by curving the sides of the teeth downwardly whereby the teeth sides are angularly projected through the plane defined by the bottom surface of the blade. The cutting edges along the sides are formed by grinding faces through the portions of the teeth projected below the bottom surface of the blade. The faces (42) are formed in a single pass of the grinding implement (64) with the faces parallel to the bottom surface (38) of the blade.

Abstract: The process tests the quality of the electromagnetic screening of a conducting lead which consists of a shielded cable (1) with at least one conductor (10, 11) in this cable and a shielded connector (2, 3) at each end of this cable. The process involves injecting into the shielding (14, 25, 35) of the lead a transient perturbing signal Ip(t) of predetermined value and shape, and measuring the resultant signal (Vr(t), real) appearing on one of the cable conductors in response to the passage of the perturbing signal. The resultant signal is compared with a reference signal (Vr(t), ref) appearing on the conductor of a lead identical to the one under test and supplied with the same perturbing signal. The aim is to find out from the result of the comparison whether the screening is correct, doubtful or poor. Application to the evaluation of the quality of the screening of leads packaged in coils. <IMAGE>

Abstract: In a ball-game racket, specifically especially in a tennis racket, having a frame, an open and closed throat piece and a shaft (2) adjoining the throat piece, the frame, the throat piece and the shaft being of integral construction or being connected to one another non-detachably, a handle part (1), constructed as an integral sleeve, can be pushed over the shaft (2). The inside profile of the cross-section of the handle part (1) and the outside profile of the cross-section of the shaft (2) have support surfaces which extend longitudinally and interact positively with one another. The spacing between the support surfaces of the shaft (2) and the support surfaces of the handle part (1) is tapered conically in the direction towards the free end (11) of the shaft (2). Connected detachably to the shaft end (11) is a removable spacer (3) which prevents the axial pushing-on movement of the handle part (1) into the position of use. When the spacer (3) is placed on the shaft, the racket can be tried out with different handle parts (1). When the spacer (3) has been removed, the handle part (1) is pushed completely onto the shaft (2) and is connected virtually non-detachably to the latter (Figure 4).
