Abstract: REVERSE TAB CONTROL SYSTEM FOR TYPEWRITER          Abstract:  A typewriter has a Keyboard (12), including a Tab Set Key (22), a Tab Clear Key (24), and a Tab Actuating Key (26).  Oper-ation of the tab set key stores stop positions of the Carrier (18) with respect to the typewriter's Platen (14). Shallow de-pression of the tab actuating key causes the carrier to move for-ward (right) to the next tab stop position.  A first deep de-pression of the tab actuating key establishes a Reverse Tab Mode causing the carrier to move backward (left) to the nearest pre-ceding tab stop position and causing the platen to rotate (in-dex) so as to position the Printing Element (16) one line down on the paper, thereby to facilitate typing the next line of sin-gle column material without effecting a carrier return and for-ward movement of the carrier to the beginning of the column. Each subsequent shallow depression of the tab actuating key causes the carrier to move backward to the next preceding tab stop posi-tion without indexing, thereby to facilitate typing the next line of multiple column material without effecting a carrier return and forward movements of the carrier,.  The Reverse Tab Mode can be ended by activating almost any other key, whereupon subsequent shallow depression of the tab key causes the carrier to move for-ward in normal fashion.

Abstract: RCA 77,211 Abstract of the Disclosure A digital filter is provided which produces two output signals exhibiting different output characteristics in response to an input signal.  The digital filter includes delaying means comprising a shift register having a plurality of signal taps and a given time delay between its input and output.  The delaying means also produces the input signal delayed by at least half the time delay of the shift register.  The filter also includes signal coupling means, coupled to the taps of the shift register, for weighting signals passing through it. Circuitry is provided for producing a sum of tap-weighted signals, and is coupled to the signal coupling means and cooperates with the shift register.  Two combining means are also included.  The first produces a combination in one sense of the tap-weighted signal sum and the delayed input signal at one output.  The other produces a combination in the other sense of the tap-weighted signal sum and the delayed input signal at the other output.

Abstract: Abstract A controller driven revolving door system has facing spaced apart curved panels partially enclosing three equiangularly spaced center shaft coupled wings and defining entry and exit openings.  The controller automatically selectively directs traffic flow through the entry and exit openings and is responsive to a microwave motion detector at the entry and a mat switch in a quarter-point position accessable to the exit.  A DC motor is coupled by a gearing assembly to the center shaft.  The controller monitors current passing through the motor windings sensing shaft rotation.  Responsive to the mat switch, the controller applies a resistive load to the DC motor windings to regeneratively brake the rotation of the door.  The controller thereafter reverses the polarity of the motor windings causing the door to rotate in a reverse direction and back any individual out of the exit area.  Drum edge switches on the curved panels sense interference with foreign objects  to cause the controller to regeneratively brake, halting rotation of the center shaft.  A handicapped person switch is provided to reduce motor current and reduce shaft rotation speed.

Abstract: ABSTRACT: Method of and device for determining the NMR-distribution of spin nuclei in a region of a body.           The invention proposes a method and a device in which free induction signals (generated for NMR imaging) are sampled in the presence of a (quasi-)static and time modulated gradient magnetic field, the gradient direction of the fields applied being mutually perpen-dicular. The free induction signal is conditioned prior to the start of sampling and then provides sampling signals which are associated with image frequencies (in an image frequency space (kx, ky) which is the (2-D) Fourier transform of the actual (x, y) image space) which are a function of the applied gradient fields. The (quasi-) static gradient field always produces a (stepwise) increase (for example, in kx), whilst the time modulated gradient field always produces an image frequency which varies between two limits (ky and ky + .DELTA.ky). Consequently, the invention enables data to be determined within an entire band in kx, ky space at a time; this is in contrast with the present state of the art (DE 26.11.497) where data can be collected only along a single straight line at a time (kx or ky is constant).

Abstract: ABSTRACT       A radio direction finder uses  a pair of antennas  (41,42)  in which each antenna is skewed from a preferred null alignment (46) by a predetermined  angle  (0).    The  skewed  antennas   (41,42)   receive signals at a level which is greater than the level that either antenna (41,42) would have if individually aligned in its null position (43).          Received signals detected by the  antennas  (41,42)  are  amplified  in appropriate  circuitry  (51-54)  and  compared  to  one  another  at  a comparator (55).  When the antennas (41-42) are aligned so that their nulls  are  at  an  equal  angle  (0)  from  the  direction  (57)  of  a received signal, the comparator (55)  indicates a minimum differential signal corresponding to the preferred null alignment (46) parallel to the received signal direction (57).     By  detecting  a  signal  strength  with  each  antenna  (41,42) aligned  at an  angle  (0)  from  its  null  (43),  the  signal  strength received by the antennas (41,42) is relatively high compared to signal strength at each antennas's (41,42) null alignment (43).  The ability of the present invention to overcome noise further permits inexpensive direction finding techniques to be used with  lower frequency radio signals.

Abstract: BOX SPRING AND METHOD OF STORING SAME     ABSTRACT OF DISCLOSURE     A box spring is condensed along its depth dimension and then packaged in this depressed state for storage and/or transportation.  At its point of use, the box spring is unpackaged and expanded along its depth dimension for use.          Within the box spring are a plurality of support springs movable from retracted, unstressed positions enabling the aforementioned compaction of the box spring,to extended positions which provide the resilient support of the box spring when placed into use.  In the preferred form of the invention, the springs are made from spring wire or similar material formed into a sinusoidal shape including generally coplanar wavy or sine portions.  The springs are mounted such that movement of the upper support surface of the box spring relative to the base will cause the springs to move into their extended or erect positions to provide resilient support for use of the box spring or to enable the box spring to be depressed into a compact mass for storage or shipment.  Releasable means are provided to hold the box spring in its expanded, use position.  In the preferred embodiment disclosed, this is achieved through the use of diagonal dies interconnected to and between diagonally opposite locations within the box spring.  In one embodi-ment, the ties are manually secured in a tensioned state to hold the box spring in its use position, and manual release of the ties allows the box spring to be depressed into its storage position.  In another embodiment, the box spring is foldable into two overlying sections which releases tension in the ties and causes the springs to move into their retracted positions to decrease the depth of the folded box string.  Unfolding of the box spring sections conversely erects the springs and tensions the ties to hold the box spring in the use position.
