Abstract: In the position shown in Figure 1, all the switching strips (4) protrude beyond the supporting rollers (2), which are mounted between side walls and are driven at the accumulation zones A, B and C by the drive belt (3). This is guided along the supporting rollers (2) by the belt rollers (5) in the raised position. The accumulation zone A is the front accumulation zone of the conveyor and its switching arm (10A) has been brought into a preparation position by an external switching element (not shown) in the form of a valve or limit switch, that is to say the condition required for the accumulation operation which is to be carried out has been provided by the external switching element in a pneumatic or electric logic circuit. This condition can also be implemented by a switching strip (4) being swivelled by an article being conveyed at an accumulation zone which is disposed in front of the accumulation zone (A). The switching strip is designed as a two-armed lever and actuates a switching element 8 with its lower lever end. This element is also connected to the logic circuit via control lines.

Abstract: In a thermal-radiation detection system, the thermal radiation (3) incident on a group of pyroelectric and/or ferroelectric infrared detector elements (20) is modulated at a frequency (f). The detector elements (20) are mounted on flexible platform areas of an insulating substrate (10) which may be of an elastic material such as a silicone rubber in, for example, an apertured or recessed mount (18,19). The grooves (15,16) forming the platform areas have a sufficient depth d and width w that the distance (2d + w) is at least as large as the thermal diffusion distance at the modulation frequency (f) so as to reduce thermal cross-talk between the detector elements (20). The elasticity and vibration absorption properties of an elastic substrate (10) and the flexibility and path length increased by the presence of the grooves (15,16) can provide a low microphony mounting arrangement with acoustic decoupling between detector elements (20). Preferably the groove depth d is at least as large as the thermal diffusion distance so as to reduce thermal losses from each detector element (20) and increase the acoustic path length and flexibility of the mounting. The substrate (10) may be moulded with the grooves in its face (11), or the grooves may be cut with a saw.

Abstract: 1. Hierarchical synchronisation method for the nodes of a telecommunication network. 2.1. Hierarchical synchronisation methods for the nodes of telecommunication networks are known with synchronisation identification allocated differently from node to node, where, with the aid of the synchronisation identification, the node with the highest clock priority (= clock master) can be determined and in which a synchronisation identification can be transmitted from each node and each node stores the synchronisation identification with the highest clock priority. 2.2. For a hierarchical synchronisation method in which a fast and error-free network synchronisation can be guaranteed at all times under all operating conditions of the telecommunication network, it is proposed that, in order to transmit the synchronisation identification, a synchronisation message be formed from the stored synchronisation identification and from any stored codes through addition of a code which identifies the transmitting node, and that all the codes added to this synchronisation identification are stored along with the synchronisation identification. 2.3. The preferred field of application for the invention is in node networks with constantly changing network topology and clock hierarchy.

Abstract: In a semiconductor chip (100) a memory cell unit (102, 105) and a diagnostic unit (111) are coupled to an output buffer unit (114) through a single data path (113). An auxiliary gate control unit (115) is provided for causing an output data pin (Pout) to be switched between a high level, a low level and a high impedance state in testing functions. diagnostic unit (111) checks a plurality of data bits from the memory cell unit (102, 105) to see whether or not the data bits are consistent with one another, and in response produces a first diagnostic signal of either high or low level in a basic testing function. For three state testing the diagnostic unit (111) can produce second and third diagnostic signals for shifting the output data pin (Pout) between the high and low levels and a high impedance state. The auxiliary gate control unit (115) steers the output buffer unit (110) in response to the complement (CTFAIL1) of the first diagnosis signal, to the third diagnosis signal supplied thereto on the single data path (113) and to the second diagnosis signal applied thereto indirectly through a controlling unit (112). The second diagnostic signal indicating inconsistency causes the auxiliary gate control unit (115) to set the output buffer unit output pin (Pout) in the high impedance state.

Abstract: Adjustment and maintenance of a phase relationship between a video signal (on 11) and a scan synchronizing signal (on 67) to assure proper horizontal centering is provided in a horizontal deflection system (40). A first phase locked loop generates a first timing signal (on 17) at a first frequency, synchronously with a horizontal synchronizing component in a video signal. A presettable counting circuit (in 56) operates synchronously with the first timing signal for dividing a clock signal to generate a second timing signal (on 61) at a second frequency. A second phase locked loop (62) generates a scan synchronizing signal (on 67) from the second timing signal. A microprocessor (74) may supply different numbers to a register (in 56), the output of the register being coupled to the presettable counting circuit. Different numbers (from 74) change the relative phase between the first and second timing signals by incremental steps. The microprocessor (74) monitors a video source selection switch to gate one of alternative video sources as a video and synchronizing signal output and adjusts the relative phase between the horizontal synchronizing component of the selected video source and a synchronous timing signal by a factor appropriate for the selected video source. A manually operable circuit (72) may be coupled in a feedback path of the second phase locked loop (62) for adjusting the relative phase between the second timing signal (on 61) and the scan synchronizing signal (on 67), over a range corresponding to an incremental step.

Abstract: The present invention relates to an equivelocity universal joint suitable for coupling shafts, and for an axial piston pump. 
     One ends of the driving pins (5) of the equivelocity universal joint rotate along a predetermined locus on a concentric circle while rotating and sliding by themselves in the cylinder bores (6, 8) of the driving (1) or driven (2) shaft. Spherical head portions (7) of the other ends perform rotating motion in cylinder bores or ball receiving bores of the driving or driven shaft. Accordingly, the respective driving pins continue linear sliding motion in response to the rotation of the driving or driven shaft and thereby the spherical head portions of the other ends are held at the concentric circle on the driving or driven shaft so as to keep the driving center in floating state. 
     As a result, the respective pistons are driven on a concentric circle, thereby an equivelocity universal joint is realized and the mechanical vibration thereof is substantially eliminated.

Abstract: In the injection molding of closure caps, the problem of demolding the safety-seal strip, which is suspended at an intended break line and is necessarily provided with undercuts, is encountered. Here a clearance must first be created at the lower outer surface of the safety-seal strip, and the safety-seal strip must then be stripped from the mold core together with the closure cap. As a practical method step, the invention proposes to bring about the release of the lower portion of the outer surface of the safety-seal strip by lowering a mold ring which is displaceable relative to the stripper plate.
