Abstract: Abstract A projection lens is mounted between a movable stage and a stationary holder to project an image of a reticle held by the holder onto a semiconductive wafer held by a chuck mounted on the stage.  The stage is movable along orthogonal X and Y axes in a horizontal plane to align different regions of the semicon-ductive wafer with the projected image of the reticle.  First and second movable plane mirrors fixedly mounted on the stage for movement therewith are symmetrically disposed relative to the Y axis in first and second vertical planes intersecting one another at the Y axis.  Similarly, first and second stationary plane mirrors fixedly mounted on a housing of the projection lens are disposed parallel to the first and second movable mir-rors, respectively.  As the stage is moved along the X and Y axes, first and second interferometer systems provide first and second measurement signals indicative of the velocities of the first and second movable mirrors (relative to the first and second stationary mirrors) while they are being moved along first and second measurement paths normal to the first and second movable mirrors, respectively.  In response to the sum and the difference of these measurement signals, first and second position control circuits move the  stage along precisely orthogonal X and Y axes with the Y axis bisecting the angle between the first and second movable mirrors.  Each of these position control circuits may be provided with a variable phase shifter responsive to a reference signal and a control signal for producing an output signal of the same frequency as the reference signal but shifted in phase as determined by the control signal, and with a phase detector respon-sive to the output signal from the variable phase shifter and to the first or second measurement signal for producing a position control signal proportional to the difference in phase between those signals. The sum and the difference of the position con-trol signals of selected phase produced by the position control circuits are employed to extend the resolution of the position control circuits.

Abstract: TWO-STAGE DEADMAN CONTROL FOR WALK-BEHIND MOWERS               Abstract of the Disclosure A self-propelled walk-behind mower includes blade and trac-tion drive clutch control levers associated with a deadman control lever which operates a pair of lever latches such that it is necessary for the deadman control lever to be held depressed against the guide handle of the mower to allow the blade and traction drive control lever to be held in respective clutch-engage positions, the control levers being biased to automatically return to respective clutch-disengage positions once the deadman control lever is released.  A pair of latch release levers are respectively operative to selectively actuate one or the other of the lever latches so as to permit one or the other of the blades and traction drive control clutches to automatically return to its clutch-disengage position when the deadman control lever is held depressed against the operator's handle.

Abstract: ABSTRACT     Packing containers of the non-returnable type for the packaging of milk, etc, frequently have a fold-out pour-ing spout which is intended to facilitate the pouring out of the milk in a concentrated jet.        However, the air which must enter the package via the pouring spout at the same time as the pouring out takes place causes the flow to stop periodically so that the pour-ing out occurs jerkily.        This disadvantage is overcome in accordance with the invention in that the spout is designed to have an emptying duct as well as an air duct. The air duct extends into the packing container over such a length that air can pass un-hindered into the packing container without disturbing the flow of the contents through the pouring spout.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is provided for continuously laying concrete.  This apparatus includes a movable frame with an attachment mounted on the frame for receiving concrete in a plastic condition.  A slip-form paving machine is attached to the frame behind the receiving attachment for shaping the concrete into an elongated concrete slab.  Apparatus is attached to the frame for forming a continuous groove on at least one edge of the concrete slab.  Another attachment is provided on the frame for lining the groove with a lining.  A punch mechanism is provided for punching a plurality of holes in the lining.  An automatic bar mechanism is also attached to the frame for automatically placing bars into these holes.  Because it is difficult to assure that such bars are properly placed in the holes and since an improperly positioned bar can cause serious damage to the keyway and pavement already laid, a mechanism is attached to the frame for shutting off the paving maching if the bar placing mechanism malfunctions so that the bars are not properly placed. Thus, not only is an improved bar inserting mechanism provided for a key-way forming machine, but also an improved mechanism is provided which shuts down the slip-forming machine if the bar becomes jammed.

Abstract: 24                  48,377 ABSTRACT OF THE DISCLOSURE A grounding arrangement for a shutter for a high voltage metal clad switchgear arrangement is taught.  The shutter  is  a  composite  of  an  electrically  insulating material  such  as  polyester and islands of electrically conductive material,  such as non-magnetic aluminum.   The polyester  material  reduces  the  chance  for  flash-over between the high voltage conductors and the grounded metal islands  or other  conductors,  while  the  grounded metal. islands provide a region of zero ground potential in an area  associated  with  the  openings  of  the high voltage terminal  assemblies  to  thus  assure  that  personnel  who approach this region will always be exposed to ground po-tential and not high voltage potential.  When the shutter is raised, a dual switching arrangement is automatically actuated to disconnect the islands of the shutter from the ground potential of the metal clad switchgear.

Abstract: Automated Blood Pressure Measurement During Physical Exercise Abstract An inflatable blood pressure cuff is volumetrically contiguous with a reservoir, and has a microphone mounted on the inside cuff surface.  Electrocardiograph signals are obtained, and the cuff is first inflated, then incre-mentally deflated.  At each pressure increment, and for a number of heart beats dependent on the subject's heart rate, data acquisition is gated based on cardiac R-waves. In particular, a first plurality of microphone signal samples are taken, approximately about the R-wave occur-rence, and a second, larger and subsequent plurality is also taken.  Sample combination techniques yield indices respectively representing noise and signal plus noise, and at least at the first instance when signal exceeds noise by a specified amount, a Korotkoff sound is deemed to have occurred, and systolic pressure is identified. Subsequent deflation and similar processing is utilized to detect diastolic pressure, which occurs when the Korotkoff sounds decrease rapidly or substantially cease.

In one locking position of a toggle element swingably carried by the intermediate member it engages an upwardly facing surface of a ledge on the load member, constraining the intermediate member to move with the load member in a lower part of the range of vertical motion of the load member; in the upper part of that range the toggle element, in an opposite locking position, engages an upwardly facing surface on a ledge on the inner member so that the latter supports the intermediate member.  The position of the toggle element is controlled by a pair of latching elements carried by the intermediate member at opposite sides of the toggle element, each movable up and down relative to the intermediate member and biased up to a latching position holding the toggle element in one locking position; but each latching element can move to its latching position only when the other is out of that position.  The latching elements are displaced out of their respective latching positions by a dog on each, each dog engageable with a downwardly facing surface on one of  the ledges.
