Title: Bobsled

Granted: 1982-12-07
Abstract: Abstract of the Disclosure A bobsled (10) provides steering control for all four of its runner assemblies (22 and 23).  The left runner assemblies (22 and 23) are coupled through tie rods (55 and 56) to the right runner assemblies (22 and 23), and these assemblies (22 and 23) are coupled through a steering linkage (31, 36-42, 45, 46, and 49-54) and cables (62 and 66) to a push-pull pair of control levers (57 and 58).  Operation of the levers (57 and 58) moves the linkage axially to pivot front and rear bell cranks (45 and 46) counter to one another, resulting in the rear runner assemblies (23) being pivoted counter to the front runner assemblies (22) to follow an arcuate track through a turn.  The steering system extends through the front and rear axles (68 and 69) which are coupled to the frame (12) through a suspension system and which are allowed to pivot in plates transverse to longitudinal axis of the bobsled (10).

Abstract: CONTROLLED THERMOFORMING It is known to injection mould or blow mould materials such as polyesters. However, such procedures are cumbersome, time consuming, and are relatively expensive. There is a need to increase the rate of moulding from such material by thermoforming while at the same time controlling the degree of crystallinity in the plastic. The present invention overcomes this drawback by providing a method for the production from thermoplastic material of mouldings whose partially crystalline condition can be controlled by physical effects, temperature effects, or both, comprising: forming a continuous extrusion; stabilizing the extrusion by cooling at least one surface; thermal conditioning the stabilized extrusion to produce thermal deformability; and thermal deformation to produce form stable mouldings from the extrusion characterised in that in the production of mouldings from such plastics material, whose crystalline state can be controlled from amorphous to a specific degree of crystallinity, the desired crystallinity condition is produced in the moulding wall by a first thermal conditioning operation performed on the semifinished extrusion and by a second thermal conditioning process performed on the moulding; the physical effects to be performed in the course of the first thermal conditioning operation between stabilization and thermal forming are adapated and modified in predetermined manner to give a desired preparatory crystallinity and thermal deformabiltiy of the extrusion and a temperature gradient which is controlled through the cross-section of the extrusion, and leads to the desired final crystalline state in the plastic material of the moulding wall and is adapted to the ensuing thermal deformation process, and the second thermal conditioning process is carried out at least during the thermal deformation process with temperature control to produce or maintain the desired final crystallinity state in the plastics material of the moulding wall in conjunction with obtaining form stability.

Abstract: Massey, J. R. 1 SPLICE CASE WITH GAS TIGHT SEALING GROMMET        Abstract A sealing grommet, used in cable splice cases for connecting multiconductor telecommunication cables, comprises a unitary elastomeric body with cable receiving passageways.  Each passageway is defined by an interior sidewall from which a plurality of longitudinally spaced circumferential ridges extend.  For a substantial portion of its circumference, each ridge has an axis of projection which forms an oblique angle with respect to the axis of the passageway and is sufficiently elongated in longitudinal cross section so as to be capable of flexing with respect to the axis of projection during cable insertion and enlarging its opening diameter to accommodate and form a radial seal about a cable being inserted.

Abstract: ABSTRACT OF THE INVENTION           An on-line filtration system for the removal of macromolecules greater than 70,000 mol. wt. from a physio-logical solution, such as blood, in the therapeutic treat-ment of various disease states.  For blood, the plasma (which contains the macromolecules) is separated continu-ously from the blood using a first membrane filter with a membrane porosity of nominally 0.2 to 1.0 micron.  The separated plasma is then continuously filtered in a physi-ological temperature state or a cooled state through a second membrane filter with a membrane porosity of nomi-nally 0.01 to 0.2 micron, which retains the macromolecules. In the cooled state, separation of the macromolecules is effected more efficiently than could be done in the non-cooled state.  The treated plasma (macromolecules removed) is then reunited with the blood flow coming from the first plasma filter and returned to the patient.  The blood flow and filtration processes are generally continuous.  Suit-able agent(s) may be added to the separated plasma to promote formation of macromolecules.

Title: Filter arrangement for an air circulatory system

Granted: 1983-07-19
Abstract: Filter Arrangement for an Air Circulatory System Abstract In an air circulatory system of the cab of an earthmoving vehicle it is desirable to have a source of ambient fresh air combined with existing cab air flowing through the air conditioning unit.  It is common practice to pass both sources of air through one filter which adversely affects the effectiveness of the air conditioning unit.  When separate filters are provided for each source of air, however, serviceability has often been sacrificed by having the filters placed in a location that is not easily accessible.  The air circulatory system of this invention overcomes these problems by providing two filters which are cooperatively mounted within an assembly that directs the first ambient source of air through both filters while providing a chamber which mixes the cabin air with the ambient and directs the combined air only through the second filter.  The chamber provides a passageway that is sufficient in size to provide an adequate air flow through the air conditioning unit at all times.  The filter assembly is provided with mounting guides which allow the filters to be easily serviced from a common service point without concern for the destruction of seals that are bonded to each filter to prevent the ingress of air which has not been filtered.

The sleeve valve is latched in its port-closing position but is readily displaced to its open position when a gas lift valve or other flow control device is installed in the receptacle.  When the flow control device is withdrawn from the receptacle, the sleeve valve is returned to its closed position, there being provision for automatically coupling the sleeve valve and flow control device together in end-to-end relation in response to the flow control device being installed in the receptacle and for automatically uncoupling them in response to removal of the flow control device from the receptacle. The seals carried by the flow control device seal in the same bore in which the seals of the sleeve valve engage and are, therefore, equal in diameter.

Abstract: ABSTRACT A paging receiver having a built-in antenna is described.  In conventional receivers of this type the effective loop aperture area of the antenna is reduced by proximity to the antenna of a metal member forming part of the receiver, which metal member is maintained at a potential equal to the ground potential of the antenna.  This means a reduction in gain.  To overcome this problem the receiver of the invention has a higher frequency operative cir-cuit section associated with the antenna circuit and a lower frequency operative circuit section.  The receiver also has a high impedance circuit for connecting the two operative sections.  The high impedance circuit exhibits a high impedance to the higher frequency so that the ground line of the lower frequency operative circuit section has a high impedance to the loop antenna.  This increases the effective loop aperture area of the antenna thus improving the gain.
