Title: Fastener assembly for clamped wheels
Inventor: HLINSKY EMIL J
IPC: F16B31/04
Filed: 1983-09-19
Abstract: A fastener assembly for clamped vehicle wheel installation includes a nut (36) engageable with a wheel hub supported stud and a resiliently deformable clamp washer (30). A washer clamp surface (44) engageable with the wheel is frusto-conical and inclined to the radial direction at an initial clamp surface cone angle B. Interfacing frusto- conical bearing surfaces (48 and 46) are defined on the nut (36) and clamp washer (30) and define an initial bearing surface separation angle A at least as large as the initial clamp surface cone angle B. The nut bearing surface (48) is inclined at an angle C having a tangent not greater than the coefficient of friction at the bearing surfaces to avoid subjecting the clamp washer to undesirable hoop stresses. Substantial spring forces are achieved with a compact assembly because the axial offset of the clamp washer is substantial in relation to the radial offset. Radial clamp washer offset provides a differential in friction radii to prevent rotation of the clamp washer relative to the wheel. <IMAGE>

Patent GB-2182826-A (GB)
Title: Data transmission system
Inventor: FISHER DAVID ANTHONY
IPC: H04L7/08
Filed: 1985-11-20
Abstract: In a data transmission system data is sent, after suitable conversion, as a ternary analogue type signal. Using two-wire twisted pairs and hybrids, echo cancellation and feedback equalization are needed. Synchronization between the two ends, e.g. of a 144 Kb/sec. subscriber's loop, is maintained by a low amplitude pilot tone sent with the data, which is detected at the same time as the data is detected. Detection and elimination of this pilot tone use coefficient generation circuitry similar to those used in the equalizer and echo canceller. To reduce the effect of time phase steps on the system performance, in addition to the transmission of a specific zero valued frame synchronization word which immediately precedes the phase step, the incoming synchronization word is also aligned to this time so that the value of a symbol as received can be predicted, as for a synchronization word, the predicted value is given preference if there is a difference between that symbol's value as received and its predicted value. In addition, the location of the high-pass filters used in the system are specified, alternative methods of bit timing control are specified and advantageous realizations of the canceller and equalizer using tap interpolation are disclosed.
