Abstract: ABSTRACT OF THE DISCLOSURE Read only memory system employing an array of memory elements each of which stores 256 8-bit word segments. Each program word to be read out of the system contains 20 bits. The first 8 bits of a program word are stored in a word segment of a first memory element and the second 8 bits are stored in the corresponding word segment of a second memory element. The last 4 bits are stored in 4 bit positions of the corresponding word segment of a third memory element. The other 4 bit positions of this word segment contain the last 4 bits of another program word which has its first 16 bits stored in two other memory elements. The desired program word is read out by addressing the appropriate word segment of every memory element of the array, and by applying memory element select signals to the three memory elements containing portions of the desired program word. The memory element select signal to the third memory element is generated by the memory element select signal to the first and second memory elements. Such a signal to the third memory element would also be generated if the other program word were the program word des-ired. The first 16 bits are read out of the two memory elements directly in parallel. The 4-bit portions of the two program words in the same word seg-ment of the third memory element are read out to two separate gating arrange-ments. The memory element select signal which is applied to the first two memory elements is also applied to the gating arrangement receiving the 4-bit portion of the desired program word. Thus, the last 4 bits of the desired program word are read out through the one gating arrangement while the last ? bits of the other program word from the same word segment of the third mem-ory element are blocked by the other gating arrangement.

Abstract: ABSTRACT OF THE INVENTION     A braking system has been designed for controlling the rotational momentum of a cover collecting drum during the extention and retraction sequence of a motorized swim-ming pool cover apparatus.  The braking system provides a compact, substantially even roll on the collecting drum.          The swimming pool cover apparatus includes a rotatable and axially slidable shaft supportably carried by a number of end bearing standards.  A fixed, free wheeling, cover col-lecting drum is carried on the shaft along with a pair of tree wheeling, draw cord collecting reels positioned at each end of the drum.  A clutch-like system is provided whereby the drum and the reels can be selectively engaged and/or disengaged from the shaft by rotating the shaft first in one direction then in the other.  To maintain a desired, preselected tension on the pool cover and thereby produce a compact, even roll on the cover collecting drum the rotational momentum of the reels and the cover collecting drum is controlled during operation by the application of an adjustable braking force to each of the reels.  This braking force is achieved by squeezing or pinching a pair of brake shoe against the side walls of each of the reels.          Since the force applied to the reel's side walls is adjust-able, the braking force applied to the reels may either be identical or dissimilar depending upon the type and degree of compactness or tightness desired.  A unique feature of this braking system is that the desired amount of force can be applied concomitantly to both side walls of each of the reels and thereby insure a uniform roll on the cover col-lecting drum.

Abstract: DUPLICATING MACHINE                 Abstract of the Disclosure A duplicating machine has an impression roll positioned to press copy sheets against a master sheet on a drum which is rotatable by an electric drive motor through a coil spring type clutch.  The clutch consists of a coil spring having an inter-ference fit with cylindrical friction surfaces on driving and driven clutch members which are connected respectively to the motor and drum.  The coil spring is helically wound in a direction to tighten the interference fit when the motor rotates the driving clutch member to turn the drum in a printing direc-tion; conversely, the interference fit loosens when the driving end of the coil spring is held, enabling the driving clutch member to rotate freely.  A tang on the driving end of the spring is positively connected to a cylindrical release collar surrounding the spring.  The driven end of the spring has a positive tang connection to the driven clutch member and drum.          Thus, rotation of the release collar and drum are synchronized within a range determined by the torsional elasticity of the spring.  A stop arm is movable to and from a stop position engaging one or more detent recesses in the release collar.          Engagement of the stop arm within one of the recesses, at the end of a printing run, automatically stops the collar.  This disengages the clutch by releasing the interference fit between the spring and the driving clutch member.  The drum stops at a position determined by the stopped position of the release collar.     A plurality of detent recesses are circumferentially and axially spaced about and along the axis of the release collar.  The stop arm is selectively engageable with one or the other of the recesses to stop the drum at different rotated positions to enable the ends of different length master sheets to clear the impression roll.  A manually operable starter arm assembly releases the stop arm from the detent recess on the release collar and simultaneously closes a switch to actuate the drive motor.  Conversely, when the last copy sheet is fed into the machine, the stop arm automatically drops into the selected recess to stop the release collar to disengage the clutch while simultaneously opening the switch to deactuate the driving motor and allow the drive train to coast to a stop.
