Abstract: ABSTRACT OF THE DISCLOSURE    Side members which extend along each side of an engine compartment are designed and arranged so that they will buckle out sideways during a frontal collision to absorb initial impact energy.  This prevents the engine from being pulled upwardly in the vehicle and allows same to be driven rearwardly to stagewisely crush structual panels to absorb further impact energy.          The movement of the engine directly rearwardly also allows for the cross member/side sill chassis construction to receive and dissipate the energy not absorbed through panel deformation.  Accordingly, the forward bulkhead is not directly deformed by the engine which would otherwise occur if the engine were forced upwardly by the impact.

Abstract: Abstract of the Disclosure A power supply for a high intensity discharge lamp is provided wherein the secondary windings of a pair of lamp strike pulse transformers are connected in series with the HID lamp directly across the AC supply, the impedance of these secondary windings acting as the only ballast elements of the power supply.  The HID lamp is chosen to have relative-ly high operating and maximum starting currents so that warm-up time of the lamp is dramatically reduced while employing the lamp strike pulse transformers to perform the dual func-tion of starting the lamp when either hot or cold and acting as the current limiting ballast for the lamp both during warm-up and under normal operating conditions.

Abstract: ABSTRACT Side lasting machine has a last support and two side lasting assemblies each comprising a plurality of lasting fingers, a plurality of clamp pads arranged beneath the fingers, one associated with each pair of fingers, and, depending from each finger and interposed between the pads and the upper, a plurality of lasting bands.  Each band extends over the width of not less than two fingers; preferably in the region of the two most heelwardly disposed pairs, a single band is provided.  Each pad is mounted for independent pivotal movement about a vertical axis, to enable it to conform more readily to the last contour.  The pads hold the bands against the upper under a pressure sufficient to allow slipping therebetween, the band thus applying an updrafting force to the upper as the fingers move inwardly.

Abstract: ABSTRACT OF THE DISCLOSURE            A liquid level sensing apparatus (32) senses the level of liquid surrounding the apparatus. A plurality of axially spaced sensors (36) are enclosed in a separator tube (86). The separator tube (86) tends to collapse the level of a two-phase fluid within the separator tuba into essentially a liquid phase and a gaseous phase where the collapsed level bears a relationship to the coolant inventory outside the separator tube. The level of the liquid phase is sensed by level sensing apparatus (32). The separator tube (86) contains inlet-outlet ports (90,92) near the top and bottom thereof to equalize the liquid level inside and outside the separator tube (86) when the level fluctuates or the water within the separator tube (86) flashes to steam. Each sensor (36) is comprised of a heater (64). a heated thermocouple junction (68) and an unheated thermocouple junction (66) within an elongated heat conductive housing (62).  The heated portion of housing (62) is enclosed in a splash guard (72) with inlet-outlet ports (78,82) near the top and bottom to equalize the liquid level inside and outside the splash guard (72) and to eliminate the spurious indications of liquid level change which may arise it water droplets contact the housing (62) in the region of the heater.  To prevent stear bubbles entrained in a two-phase fluid cross flow from entering the lateral inlet-outlet ports (90,92) of the separator tube (86), the separator tube (86) id enclosed in support tube (100) which may in turn be enclosed in on otherwise unused control element assembly shroud (110). The lateral inlet-outlet ports (90,92) of separator tube (86) are axially offset from interal inlet-outlet ports (102) of support tube 100 at least where support tube 100 is subjected to cross flow.  The shroud (110) is open on the bottom and has lateral inlet-outlet ports (112) to facilities liquid level fluctuations to equalize inside and outside shroud (110).  An alternate embodiment permits the measurement of more than one liquid level.

Abstract: Title SCROLL MEMBER WITH FLEX MEMBER PIVOTED SWING LINK                     Inventor Arthur L. Butterworth Abstract A positive fluid displacement apparatus of the scroll type, having a swing link for translating the ro-tational motion of a drive shaft into the relative orbital motion of two parallel end plates.  The facing surfaces of the parallel plates have involute wrap elements attached in fixed angular, intermeshed relationship with each other. Contacting surfaces of the parallel plates and wrap elements define pockets of fluid which are subjected to changes of pressure and volume as the pockets are caused to move be-tween an inlet and an outlet by the orbital motion of the plates.          A flexible member of resilient material connects a crank post on the drive shaft with the swing link and transfers the driving force of the drive shaft to the swing link.  The flex member is rigid in tension, but flexible in bending.  By its spring force, the flex member biases the wrap elements slightly apart when the drive shaft is not rotating, to reduce the driving torque required at start-up of the scroll apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE          A digital memory comprises a charge coupled device (CCD) that includes a reference signal storage section.  The digital input to the CCD includes an input reference signal and an information signal having a plurality of data levels, for example, a digital "0" and "1".  The input reference signal includes a reference bit at the higher data level.          The reference signal storage section divides the level of the reference bit to provide a reference level signal halfway between the two data levels. Thus, any shift in the data levels due, for example, to temperature changes in the CCD, affects the reference level signal to the same degree and the reference level can be kept exactly halfway between the data levels.
