Abstract: The bogie for a rail vehicle comprises a minimum of two wheelsets and at least one passive steering device (30). Each of these connects two wheelsets (3, 3') together so that they can swivel. It has a third control lever (32) with a coupling point (31) for forming a swivel connection with a coach body. The pivot points (38, 39) for swivelling the wheelsets (3, 3') are located on one side of the longitudinal centre plane (4) of the bogie (2, 2') and the coupling point (31) for the coach body on the other side of the longitudinal centre plane (4) or actually in this. This bogie is of particular advantage on vehicles negotiating small radii of curvature such as trams and municipal railways since the flexible rubber elements used on the swivel and pivot points of the steering device have optimum conditions with regard to their angle of torsion. <IMAGE>

Abstract: A voltage controlled oscillator is formed of a plurality of cascaded inverter stages in a ring configuration. Each inverter stage is a grounded emitter circuit having an active pull-stage in order to achieve a short stage delay. The frequency of the ring oscillator is determined by the number of inverter stages, and the gain is selectable by coupling an external control voltage to only certain of the inverters. The VCO may be fabricated on a single integrated circuit along with the other circuits necessary to form a phase locked loop or other frequency generation system.

Abstract: The present invention relates to a fast packet assignment technique, and a TDMA or FDMA multi-port switching arrangement for implementing such technique. In the present technique, the total traffic in a two-­dimensional traffic matrix ( T ) from and to each of N remote service areas, regardless of destination or origination, is totaled to form separate input (R) and output (S) traffic vectors, respectively. Non-­conflicting assignments are then made from these vectors for each packet or channel available during a predetermined time period while also providing the capability of substantially reducing multi-path or antenna sidelobe interference. An M×M switch (l6) is designed to implement such technique which directs C input packets from M inputs (20 1-M ) into separate memory locations (Z ij ). During the time period of the next C input packets, the M×M switch directs the presently stored packets to the proper ones of M outputs (27 1-M ) at the appropriate time for transmission in the proper packet or channel to the destined remote service areas. In accordance with the present technique and switch, the M packets concurrently directed from memory to the M output ports can comprise more than one packet from a particular service area to other separate service areas.

Abstract: In a known extensible table, the mechanism arranged below the table tops cannot be covered by an edge panel since this leads to the insertion boards jamming with the edge panels arranged on the table tops. The extensible table according to the invention has an edge panel which is arranged on the outer edges of the table tops or insertion boards. Due to the edge panels, the mechanism arranged below the table tops is not visible. When the insertion boards are moved into the position of rest, cross-struts which can be coupled on or uncoupled allow a more rapid transverse displacement of the insertion boards which is initially brought about via a cam part when the cross struts are uncoupled and subsequently - as is known - takes place via the rotary movement of the coupled-on cross-struts. A special design of a control rail for displacing the table tops simplifies the production of the mechanism. Extensible table as furnishing article. <IMAGE>

Abstract: The composite structural panel has bottom (24), top (26) and edge layers (28) which enclose a primary core (30). The core provides additional structural strength to the panel. The edge layer (28) forms a desired panel edge angle of approximately 20° to 45°. The primary core (36) is trimmed at an angle (46) of approximately one-half the desired edge angle to form a first pressure reaction surface (48). A peripheral core (56) is positioned on the tapered portion of the primary core (36) so that the axis of the peripheral core (56) is perpendicular to the first pressure reaction surface (48). The peripheral core is trimmed to form a second pressure reaction surface (62) beneath the edge of the panel. The structure is lightweight and resists deformation of the panel edge when the panel is cured under elevated pressure in an autoclave.

IPC: G01P3/36
Filed: 1988-12-23
Abstract: A velocimeter and a method for measuring the velocity of a printing press web are provided. The velocity is measured without contacting the web by measuring a speckle pattern which is reflected off the moving web by a laser. The reflected light is filtered and detected by a linear photodetector array which is differentially connected. The photodetector array output is fed into a differential amplifier to obtain a differenced output which has a frequency that is related to the velocity of the web. The difference output is filtered through a variable filter set at a predetermined bandpass center frequency and bandwidth, and its frequency is counted to obtain the approximate velocity of the web. Using the approximate velocity, a bandpass center frequency and bandwidth is selected which provides a substantially linear response of velocity at the counted frequency. The variable filter is reset to the selected bandpass center frequency and bandpass, and the frequency of its output is obtained. The web velocity is then determined using a predetermined relationship between web velocity and frequency for the selected filter setting.

Abstract: A thermoplastic pipe liner (L) is initially formed in a cylindrical shape with a diameter slightly larger than the internal diameter of the pipe (80). The liner (L) is temporarily deformed at an elevated temperature to a different, U-shaped cross-section, to reduce its overall cross-sectional dimension to facili­tate insertion into the pipe (80) to be lined. Once inserted, the pipe liner (L) is reheated to the crystallization temperature of the thermoplastic material to cause the liner (L) to return to its original cylin­drical shape. Pressure within the liner (L) is also increased in two stages to cause the liner (L) to conform to the interior surface of the pipe (80). After expansion, ends of the liner (L) which extend beyond the pipe (80) are flared into engagement with the pipe flanges (82). For lining pipe normally containing in service fluid under pressure, the liner (L), after insertion into the pipe (80), can be mechanically reformed to engage the interior wall of the pipe (80). The normal service pressure is then used to maintain the liner (L) in its generally cylindrical shape over the time necessary to completely relieve the stresses in the liner (L) tending to cause the liner (L) to return to its deformed shape.

Abstract: The terminal comprises in-line insulation dispolacement contacts (16, 18) (Fig. 1) each comprising a pair of spaced apart generally parallel cantilevered contact arms (20, 22) defining a slot (26) (Fig. 3) therebetween. The slot (26) includes insulation piercing barbs (40, 42) and a conductor engaging portion (50, 52) having a length and width sufficient to receive the bundle of conductor strands (see Fig. 7) in the wire. The conductor engaging portion (50, 52) terminates at a pair of inwardly directed convex non-cutting bulges (54, 56) which in the unstressed condition of the terminal are in very close proximity to one another. The bulges (54, 56) define a lower limit of movement of the conductive strands into the slot allowing the insertion force to increase. The camming surfaces defined by the bulges (54, 56) act as ramps to convert the increased insertion forces of the wire into lateral forces on the cantilevered contact arms (20, 22). These outward forces provide the deflection needed to develop and maintain reliable resilient contact forces in the terminal arms (20, 22) which will be urged laterally into the wire strands and substantially reduce strand rearrangement. The insulation piercing barbs (40, 42) may be bent over the conductive strands as seen in Fig. 8 to more positively retain the wire in the terminal.
