Abstract: ENGINE INDUCTION AIR FLOW CONTROL            Abstract of the Disclosure.         In an internal combustion engine air cleaner snorkel having an end open to ambient temperature air and an auxiliary inlet open to heated air, the induction air flow temperature is regulated by a pivoted damper assembly having a guide member positioned by a coiled bimetal and a damper member biased by a torsion spring for concomitant operation with the guide member.          The damper member has a main blade portion responsive to the induction air flow rate and controlling ambient air flow and a pair of lateral blade portions controlling heated air flow but unresponsive to the induction air flow rate.  Under conditions of high induction air flow the damper member moves away from the guide member against the bias of the torsion spring to permit ambient air flow through the open end and to block heated air flow through the auxiliary inlet.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for providing a controlled movable environment in accordance with the present invention, for protection of a work area in the environment from adverse external conditions, may take the form of a collapsible and movable building structure that may be moved about in its fully erected condition.  The building may include at least one and preferably a plurality of platform devices which may take the form of trailers, self-powered vehicles, sleds or any other suitable motive device having means for engage-ment with the site on which the building structure is to rest. A lightweight building structure, which may take the form of a flexible inflatable or air supported building structure may be secured to the platform means and may cooperate with the platform means to provide a chamber for protection of the work area and any occupants or equipment for which protection might be desired.  Means may be provided for varying the effective weight of the platform means and lightweight build-ing structure to stabilize or prepare the same for movement. The effective weight is increased for the purpose of stabiliz-ing the building structure to protect it against the damaging effect of winds, while the effective weight is reduced to a desired minimum in preparation for movement of the building structure.  Motive means, such as external toeing mechanisms, powered support wheels or the like may be utilized for move-ment of the platform means and building structure when such movement is desired.

Abstract: XEROGRAPHIC DEVELOPMENT APPARATUS HAVING A LARGE RESERVOIR    FOR CONTROLLED FLOW THROUGH A NARROW DEVELOPMENT ZONE          ABSTRACT OF THE DISCLOSURE      The disclosure illustrates a novel development system for controlling the flow rate of developer through a narrow development zone, using a reservoir which has a feed chamber for maintaining a constant pressure head at the entrance to the narrow development zone.  Developer flow is initiated upon demand by means of actuation of a valve positioned between the feed chamber and the entrance to the development zone; since considerable developer mixing occurs in the developer reservoir, mixing devices for mixing added toner with carrier beads may be simplified.

Abstract: ABSTRACT         A method and composition are provided for preparing a novel acidified milk gel product, characterized by smooth body with no graininess and good flavor.  The composition comprises a novel thickener system which is a blend of carboxymethyl cellulose, xanthan gum, and locust bean gum.           The thickener is used as a level of from about 0.6-1.6 by weight based on the weight of the final total weight of the milk - acid system.  The three components of the thickener composition are present at levels of from about 30% to about 50% for carboxymethyl cellulose, from about 20% to about 50% for xanthan gum, and from about 10% to about 45% for locust bean gum, all percentages as a per-cent of total weight of the thickener composition.  The thickener system can be used for both hot and cold pre-parations.

Abstract: HIGH ENERGY ADAPTIVE IGNITION SYSTEM                         ABSTRACT       An improved ignition system uses feedback techniques to maintain a constant high energy ignition spark level over the normal range of engine RPM.  The feedback automatically compensates for environmental and aging effects such as increased ignition coil resistance and decreased battery voltage.     A voltage controlled monostable multivibrator produces pulses determining the "on" time of an electronic switch which is in series with the coil.  Current through the coil is sensed by a generator which feeds back an appropriate signal to control the monostable whereby a constant dwell time is maintained.  At very high engine RPM a second feed-back source servo-controls the system to a constant dwell angle condition.  A constant dwell angle is also established at cranking speeds by a second pulse generator in parallel with the first.

Abstract: AUTOMATIC FLAT WIDTH CONTROL                 Abstract of the Disclosure The width of a continuously moving flat material, such as a web, or a film sheet, or a flattened tubular plastic film, in manufacture or in process, is continuously monitored by non contacting sensor means which scan the material by oscillating transversely across its moving edges. Departures from a preselected desired width are detected and signals are developed corresponding to the magnitude of a departure, and to whether it constitutes an increase or a decrease from the preselected width. The signals thus developed may be translated into visual or other sensible indicia and may also be applied to make appropriate changes in process control to reattain the set point width of the material being monitored.

Abstract: AN IMPROVED CYLINDRICAL PLUG VALVE      Abstract of the Disclosure An improved cylindrical plug valve is of the type which includes a body having a cylindrical bore and a pair of axially aligned passages intersecting the bore and normal thereto.  A cylindrical valve plug is rotatably disposed within the bore for movement between an opened and closed position for respectively aligning and misaligning a diametral port therethrough with the passages.  Sealing rings around the plug above and below the port and passages prevent fluid from escaping from the interior of the plug valve.  The improvement includes a pair of cup shaped recesses at opposite sides of the plug which are aligned with the passages when the valve is closed.  Each recess is larger than the passage and has a substantially flat bottom and a peripheral side wall. A resiliently deformable sealing member inserted in the recess has a lip portion thereof extending around the peripheral side wall for surface contact therewith and is compressed between the bottom adjacent the peripheral side wall and an interior surface of the bore around the passage for sealed contact therebetween when the valve is closed.  A support structure of the sealing member prevents any region of the lip portion from being displaced from the peripheral side wall.  A plurality of openings through the sealing member communicate to the space between the bottom and the sealing member to prevent entrapment of fluid therein during closure.

Abstract: TELESCOPING ENERGY ABSORBER WITH PRESSURE RELIEF VALVE CAPSULE An energy absorber unit having inner and outer telescoping cylinders with a pressure relief valve capsule retained in a centralized opening in or forming an integral part of the cylinder cap to control the flow of fluid between contractible and expandable fluid chambers in the unit.  The valve capsule being load-sensitive maintains a substantially constant pressure in the unit so that unit stroke is proportional to impact velocity.  With this construction, the corners of vehicle bumpers experience a reduced swing arc as compared to velocity sensitive units so that clearance between bumper corners and vehicle body work can be reduced.  On rebound return spring means forces the fluid through the valve capsule which, controlling the return fluid flow, reduces the rate of unit recovery.
