Abstract: In a gas spring having a cylinder and a piston rod movable within the cylinder, braking elements are provided which brake or block the movement of the piston rod with respect to the cylinder when the interior pressure within the cylinder is reduced below a predetermined pressure. So the risk is eliminated that the piston rod when under load is unintentionally moved into the cylinder with a high velocity when the gas pressure within the cylinder is lowered below the predetermined pressure. The braking elements are spring loaded and are held in an inoperative position by adequate pressure within the cylinder.

Abstract: A system for the cyclical time-compression of a signal waveform, particularly applicable to the display of physiological waveform data from patients.  The system receives a continuous data sequence, as from an initial waveform, and continuously and temporarily stores waveform data during the trace and retrace phases (phases B \A A) of a processing or display operation or cycle and which subsequently reads out substantially all of the stored data in a time-compressed form during the trace phase(phase B) of the cycle.  The average rate at which data is read out of storage is faster than the average rate at which it is entered into storage, the ratio of the average readout rate to the average entry rate being the compression ration of the system and corresponding herein with the ratio of a full display sweep cycle to the trace portion of that cycle.  The resulting data which is read out from the time-compression system may be applied to the input of display means and comprises the initial signal waveform now in time-compressed form, such that the initial waveform is displayed in its entirety. In a preferred embodiment, periodic samples of the initial, or source, waveform are sequentially entered in a fixed access, recirculating memory (shift register) at a rate which results in apparent precession of the samples in the memory.  When the memory is "full", the

Abstract: A self-drilling anchor dowel has a drill head at one end of the axially elongated dowel and a truncated cone-shaped projection at the other end. The projection fits into an adapter or holder on a drilling device. Immediately following the drill head is a frusto-conical clamping part which tapers inwardly in the direction away from the head. A collar extends laterally outwardly from the smaller diameter end of the clamping part. The outside diameter of the collar is the same as the outside diameter of the drill head. When the dowel is drilled into a receiving material, such as concrete or rock, and the collar enters the borehole formed by the dowel, the collar prevents the borings formed in the drilling operation from being discharged out of the borehole. As the collar continues into the borehole, it compacts the borings which anchor the dowel in the borehole.

Abstract: A heat exchanger for heat transfer between two mediums comprises a tubular shell (10) and a finned tube (11) provided in the shell. One medium flows in the shell, and the other medium flows in the finned tube. The shell is divided into two chambers (13, 14), provided on either side of the finned tube, so that the medium flowing through the shell enters into the first chamber (13) which is positioned above the second chamber (14) and then flows downwards between the fins (12) into the second chamber (14). The shell has an elongate cross section, the fins of the tube abutting two opposite walls of the shell. The position of the tube within the shell can change along the length of the shell. The heat exchanger is intended for condensation of vapour, e.g. in connection with heat pumps. Vapour is then fed into the shell, and a cooling medium is fed into the tube. The flowing vapour promotes the discharge of the condensate from the fins. In one embodiment, the shell is wound to an upright coil in which the condensate is collected at the lower end of the coil.

Abstract: A molded polymer cage for a tapered roller bearing has end rings that are located beyond and extend across the large and small ends of the tapered rollers for the bearing and bridges that extend between and are formed integral with the two rings so as to form pockets in which the tapered rollers are confined. The cage not only spaces the rollers at even intervals between the cup and cone, but it further holds the rollers around the cone when the cone is separated from the cup. To this end, the bridges of the cage are located entirely beyond the pitch circle for the rollers so as to leave adequate space for the introduction and circulation of a lubricant, and each bridge along each of its side faces has two beveled surfaces, namely, an inner surface and an outer surface, both of which are planar. The outer surface is located further from the cone and pitch circle than the inner surface and is further disposed at a lesser angle with respect to the pitch circle. As a consequence, the outer surfaces of the bridges lap sufficiently over the rollers to provide the cage with excellent retention characteristics.
