Abstract: ABSTRACT OF THE DISCLOSURE         A gas pedal movement dampening arrangement has a spring assembly disposed on a base plate located directly beneath the gas pedal for a motor vehicle.  In one embodiment, the damping unit comprises a spherical hollow elastic body having an air outlet nozzle which affords a linearly progressively increasing resistance force to further downward movement of a gas pedal until beyond a certain point whereupon the resistance force decreases.  This enables free movement to full-throttle positions of the gas pedal if such is desired.  In another embodiment, the damper unit comprises a spring assembly with a U-shaped spring biasing against downward movement of the gas pedal.  Switch means operating upon movement of the gas pedal are also provided for controlling an indicator system informing the vehicle operator of his driving condition as a function of gas pedal movement. In a further embodiment, the damper unit and switch means are con-tained within a hemispherically shaped hollow body which is engageable by the gas pedal.

Abstract: ABSTRACT A probe adapted to be positioned against a body to detect a blood gas diffusing through the skin of said body.  The probe comprises a housing; a cap having an axis common to the axis of the housing and an opening in the base thereof, and also having locking means engaging the housing upon movement of the cap along the common axis for securing the cap to said housing; a membrane secured to the cap and spanning the opening in the base of the cap; detector means responsive to the blood gas diffusing through the skin for developing an electrical signal representative of the blood gas; and means emanating from the housing for conducting the electrical signal developed by the detector means to a remote location.  The detector means includes an electrode unit held within the housing and forming a domed surface which projects from the housing through the opening in the base of the cap and an electrolyte between the domed surface and the membrane.  The probe of the invention permits removal of old electrolyte and membrane and introduction of fresh electrolyte and membrane without replacement of the entire probe.  When the electrolyte and membrane need to be replaced, the cap and housing are separated and the domed surface formed by the electrode unit is cleaned.  New electrolyte is deposited either on the domed surface or on a new membrane and the new membrane carried by a new cap is brought into position by engagement of the locking means on the cap with the housing as the cap is moved axially into contact with the housing.  Such an arrangement is simpler than previous devices which have attempted to provide probes with facilities for changing electrolyte and membrane.

Abstract: ABSTRACT Improved oxygen recovery in the operation of a pressure swing adsorption system for air fractionation is obtained by passing the air, freed of water and CO2, through an adsorbent bed maintained at elevated temper-ature throughout the cycle and which is selective for retention of nitrogen, and consequent withdrawal of any oxygen-rich primary effluent product. Each adsorbent bed of a group of parallel main beds, in turn, undergoes the steps of adsorption at highest pressure followed by at least two stages of counter-current desorption by pressure let down and, at the achieved lower pressure level, purging of the bed with part of the primary oxygen-rich effluent. The purged bed is then repressured in several stages, first with desorbed gas rich in nitrogen introduced into the bed at the initial air inlet, and then brought to the high adsorption pressure level by introduction in opposite direction of oxygen-rich primary effluent product. In a preferred embodiment ambient air is passed through a pretreater section providing an adsorbent bed for removal of water and carbon dioxide. The thus purified air is compressed with consequent rise in temperature and then only partly cooled down by exchange with cooler desorbed and purged nitrogen-rich gas products withdrawn from the main adsorbent beds. These nitrogen-rich products thus heated by the exchange are employed in regenerating a water and carbon dioxide laden bed of the pretreater section. While the adsorption-desorption is operated in a pressure swing cycle, the pretreater section is operated in an independent thermal swing cycle. Alter-natively, the feed air may be compressed prior to its introduction into the pretreater and the thus generated heat utilized by heat exchange for heating the purified air effluent to be fractionated.

Abstract: UK ABSTRACT      A firearm especially for firing large calibre rounds such as rubber bullets and having a rotary  magazine which is rechargeable at any stage of depletion.  A loading arm served to guide rounds through an inlet opening in the magazine, in such a way that they are received into corresponding locations in a rotating carrier, and the carrier rotates forward on position with each additional round.   Until the penultimate round, the guide means is locked to the magazine body.  In this position, it obstructs further movement of the first-inserted round and thus prevents insertion of the final round.  Mechanism is described by which, on insertion of the final round the guide means automatically unlocks from the magazine body and locks to the rotating carrier.  In this condition it serves to keep the first inserted round locked in the magazine as it completes a full rotation to come opposite the inlet opening once more.  Mechanism for firing automatic indexing the carrier, and automatic extraction and ejection  of spent cartridges is described.

The feed tube merges with the guide tube at a shallow angle enlarging the interface between the two tubes.          Two triangular panel members extend along the interface with a first side of each lying generally on the inner cylindrical surface of the guide tube, a second side lying generally on the inner cylindrical surface of the feed tube and the third side extending angularly between the two tubes forming an inclined camming surface. The panels are spaced apart a distance capable of receiving the fastener shank but less than that of the fastener head. The leading end of the fastener is transferred gradually from the feed tube to the guide tube while the head is cammed laterally over a short length. This same or additional structure can prevent a misoriented fastener from reaching the guide tube and creating a jam.

Title: Image projection screen with decreased color shift as   a function of viewing angle, and method of  manufacture

Granted: 1984-02-14
Abstract: Abstract of the Disclosure In order to reduce changes in color balance which occur as a function of viewing angle, a 3-color projection TV system having one axial and two off-axis image projectors employs a lenticular image screen having a plurality of vertical lenticules  for horizontal light distribution, all of which have the same unique optical profile.  This profile is derived by starting with a location-dependent shape appropriate for a location directly in line with an off-axis image projector, in order to obtain an asymmetric profile.  The minor portion of the asymmetric profile is then discarded, and replaced by a mirror image of the major portion, thus producing a lenticule profile which is symmetrical but of too coarse a pitch.  That oversized profile is then scaled down to the proper pitch, and duplicated all across the breadth of the screen.  The resulting screen rotates the peak exit angle of the off-axis colors into a normal angle with the screen, producing a marked reduction in color imbalance as seen from off-axis viewing locations.
