Title: Cable lead-in
Inventor: JOHANNSEN OLAF
IPC: H02G3/06
Filed: 1994-01-20
Abstract: A cable lead-in (1) comprises an upper part (2) and a lower part (3). The upper part and the lower part (2, 3) are clamped together by means of a threaded joint in an opening (7) in a wall (6) on a casing around current conductors (non shown), which are connected via an electric cable (11) to other current conductors (not shown) outside the casing. The upper part (2) is formed with a through duct (10), which has an outer funnel-shaped duct section (12) and an inner threaded section (13). A seat (14) for a sealing ring (15) is formed between these two sections. A nipple (16) having a strain relief strap (20) is screwed into the threaded section (13), whereby the sealing ring (15) is pressed sealingly against both the seat (14) and the cable (11). The funnel-shaped duct section (12) serves to protect the cable (11) against damage by bending in operation. The nipple (16) has hexagonal head (18), and at least one of a plurality of blind holes (21) in the upper part (2) accommodates a self-tapping screw (23) whose head is spaced closely from one of the faces of the hexagonal nipple head (18). This protects the nipple (16) against rotation, which might cause the passage of the cable (11) through the sealing ring (15) to become non-tight. All the components of the cable lead-in (1) are well protected behind the wall (6) of the casing, while only a relatively low flange (8) on the upper part (2) is present on the outer side of said wall. In practice, this flange cannot be broken off or offer a foothold to a person who might try to stand on the flange.

Title: Track-type vehicle undercarriage
Inventor: OERTLEY THOMAS E
IPC: B62D55/14
Filed: 1994-03-07
Abstract: An undercarriage structure (12) for a track-type vehicle (10) has first and second spaced apart roller frame assemblies (14, 16) which are interconnected by a pivot shaft (18) and an equalizer bar (20). The first and second roller frame assemblies (14, 16) are so arranged with respect to the pivot shaft (18) and the equalizer bar (20) that the roller frame assemblies (14, 16 an substantially non-parallel to each other. This non-parallelism produces either "too-out" or "toe-in" of the roller frame assemblies (14, 16, which results in the endless track contacting the track rollers in different areas as the vehicle (10) travels in forward and then reverse directions. The wear life of the endless crack is thereby prolonged.

Patent CA-2163298-A1 (CA)
Title: Mode-locked fiber laser
Inventor: PFEIFFER THOMAS
IPC: H01S3/06
Filed: 1995-11-20
Abstract: The pulse repetition frequency of an optical pulse generator built with a fiber laser (LAS) is synchronized to a fixed clock frequency (fc). The synchronization is accomplished via means (M) for changing the optical path length of the resonator (RES), which is controlled by a signal from a control device (RE). The criterion for the synchronization is the effective value of an interference signal superimposed on the signal light, which increases with increasing deviation of the pulse repetition frequency from the clock frequency. A portion of the output signal (A) of fiber laser (LAS) is optically/electrically converted by the control device (RE), and the effective value of the interference signal is determined by filtering and rectifying the electrical signal obtained in this manner. After subsequent amplification and regulation, the control signal for the means (M) to change the optical wavelength is obtained. The control signal is additionally modulated with a wobble signal, so that the pulse repetition frequency always varies around the optimum value and is synchronized in this way.
