Abstract: ABSTRACT                    VEHICLE SUSPENSION     A vehicle suspension comprises an axle supported at each end by a respective axle box and respective spring means acting between each axle box and an associated rigid vehicle mounting.  The spring means has an effective spring centre which acts at a point between the axle centre and the associ-ated axle box so as to reduce the radius of operation of the suspension in a yaw condition as compared with conventional suspensions in which the effective spring centre acts at the axle box.  The yaw stiffness of the suspension is thereby re-duced enabling the axle to self-align radially as the vehicle traverses tight curves and avoid wheel slip.  The spring means comprises a pair of spring units arranged one on each side of the axle and each spring unit comprises layers of elastomeric material sandwiched between reinforcement elements.

Abstract: ABSTRACT OF THE DISCLOSURE     An injection mold for nonrigid plastics has separate mold cavities disposed on opposite sides of an inter-mediate mold part and fed from a common feed passage in one of a pair of outer mold parts defining the mold cavi-ties jointly with the intermediate mold part. The inter-mediate mold part is divided along a plane transverse to the opening direction of the mold and its two halves are connected in accordion fashion with one another and respective ones of the outer mold parts. An extractor is disposed in the dividing plane and extends through a feed cavity which communicates with the feed channel and from which runner channels extend  to the mold cavities. The feed cavity ensures a simultaneous distribution of the plastics compound to the mold cavities at both sides of the intermediate mold part upon injection, and when the mold is opened, the extractor pulls the moldings out of the mold cavities.

Abstract: TITLE     SONIC PULSE-ECHO METHOD AND APPARATUS FOR   DETERMINING ATTENUATION COEFFICIENTS            ABSTRACT OF THE DISCLOSURE      A method and apparatus is provided for determining the attenuation coefficients within a body of material by transmitting sonic pressure pulses into the material, analyzing the spectrum amplitude of the echoes returning from the boundaries within the material, calculating the attenuation coefficients of the material between the boundaries and comparing the measured coefficients to those of normal and abnormal tissue.  The wave shape of the transmitted pulses is adjusted so that the pulses generate echoes with uniform spectrum amplitude (white echoes) from each boundary within the material.  Given the characteristics of the pulses which generate white echoes from the boundary of each tissue segment and given the thickness of the material between each pair of boundaries, the attenuation coefficients of the material are calculated.  The attenuation coefficients are displayed in any manner desired, including traditional B- and M- mode displays.

Abstract: Abstract A system for reheating a product having low thermal conductivity, for example a refrigerated previously cooked meal, is disclosed.  A chamber receives the product and an air flow loop is connected through a heater, blower, input side of the chamber and output side of the chamber.  A feedback loop which cuts off the chamber is also present and a damper is positioned in the feedback loop and arranged to operate cyclically causing air flow to block off cyclically from the chamber.  The result is that pulses of air hotter than the desired reheat temperature are passed through the chamber, the pulses being spaced by intervals during which the temperature is below the desired re-heat level.  The result is rapid reheating without overheating or recooking.
