Abstract: RADIOTELEPHONE SYSTEM EMPLOYING DIGITIZED    SPEECH/DATA AND EMBEDDED SIGNALLING     Abstract A radiotelephone system is disclosed in which the signalling protocol for the system is embedded in the frame synchronization of the digital messages transmitted on the system.  Multiple system state control functions are accomplished via a high autocorrelation, low cross correlation bit sequence synchronization signal.  System state communication is achieved by utilizing a sequence of normal synchronization words and their ones complement inverses.  Reliabilty of the coding is achieved by detecting normal or inverse words as binary levels when fewer than a predetermined number of bit errors exist in the bit sequence.  If the predetermined number of bit errors is exceeded, a selected binary one or zero is substituted.  This selected sequence of binary levels is decoded and the Hamming distance between a masked decoded sequence and a masked selected sequence is calculated. If the Hamming distance calculation yields a number greater than the error correction capability of the coding function, a new set of substituted binary levels is tried, otherwise the decoded sequence is accepted as correct.

Abstract: DOOR OPERATING ASSEMBLY Abstract of the Disclosure A door operating assembly  (10)  for opening and closing vehicle  doors  at  a  constant  door  edge  force includes a frame (12).  A teeter lever assembly (24) is pivotally mounted on the frame and is connected to a connecting  rod  assembly  connecting  the  teeter  lever assembly  and  the  vehicle doors.   A cylinder  (20)  is mounted on the frame and includes a reciprocally mounted rod (22).  The rod is reciprocated by pressurized air introduced into the cylinder.  The rod is connected to the teeter  lever assembly to rotate the teeter lever assembly.  The teeter lever assembly includes a variable diameter cam (70).  A spring (62) for closing the doors is secured at a first end (64) to the frame and at  a second end  (68)  to a flexible connection member  (66). The flexible connection member connects the spring to the cam and wraps around the outer periphery of the cam upon door opening.  The energy stored in the spring at full extension is used to close the doors.  To maintain the force on the doors constant during opening and closing, the cam provides a larger moment arm in the door closed position than the door open position.  To provide closing force for the door an accumulator (76) may be provided. The   accumulator   includes   a   container   in fluid communication (78) with a vent in the cylinder.  As the doors open, air in the cylinder is forced out the vent and  into  the  container.   During  door closing, air accumulated in the container reenters the cylinder to extend the rod and close the door.  An adjustable relief valve (84) may be included with the container to maintain pressure in the container below the source pressure for the cylinder.

Abstract: A B S T R A C T       This invention relates to an improved process for preparing pulp suitable for paper making.  Although processes using explosive decompression have been known in the past, it has been believed that these must be conducted at relatively low temperatures.  Although such known processes of explosive decompression resulted in a saving of power, the physical strength was low, the color was relatively dark and there was a considerable yield loss.  This invention is to provide a process to achieve the saving of power resulting from the use of explosive decompression but in which there is good brightness, high yield and good fiber strength.  The process of this invention defines conditions for achieving these objectives.  These conditions include impregnation of the chips of other wood fragments under specified conditions and cooking with saturated steam at a high temperature and pressure followed by explosive decompression and refining.

Abstract: ABSTRACT         This invention relates to an animal litter comprising a porous, inert solid substrate and a dry, particulate water absorbent polymer.  When animal urine contacts the animal litter, there are produced gelled agglomerates containing the animal urine, polymer and solid substrate.  The gelled agglomerates have sufficient mechanical integrity to be conveyed as discrete entities thereby permitting the animal owner to remove the animal urine physically from the litter box containing the animal litter of the present invention.  Heretofore, it was not possible to physically remove urine from a litter box because urine tended to spread throughout the litter in the litter box as it was absorbed.   33,747-F

Abstract: ABSTRACT          Disclosed is a sync burst transmit phase control system for establishing and maintaining a TDMA frame between a plurality of earth stations which communicate with each other via a satellite based on an SS/TDMA (Satellite-Switched Time Division Multiple Access) system.  The system is characterized in that a metric pattern included in a sync brust is replaceable with another to select a metric pattern for realizing the ultimate synchronization accuracy at any moment with no regard to the adjustment condition of a demodulator and other external conditions.  Specifically, the system includes circuitry for, when a synchronization control operation is performed by using one of two different patterns (e.g. pattern I) for the metric pattern, averaging transmit phase correction values, which are necessary for maintaining synchronization, over a predetermined period of time so as to determine synchronization accuracy particular to the pattern I, then comparing that synchronization accuracy with synchronization accuracy particular to the other pattern (e.g. pattern II) which is determined by applying the same processing to the pattern II, and then selecting one of the patterns I and II which is higher in synchronization accuracy than the other as an optimum metric pattern, and circuitry for deciding at a predetermined period whether or not an instantaneous synchronization accuracy is lower than synchronization accuracy which is defined as a predetermined threshold value.  Synchroniz-ation accuracy immediately before the last switching and the current synchronization accuracy are constantly compared.  When it is decided that higher synchronization accuracy is obtainable with the pattern other than the one currently used, the pattern is switched.  When the current synchronization accuracy is lower than the threshold accuracy, the degrees of synchroniz-ation accuracy particular to the metric patterns I and II are compared to select one of them which is higher in synchronization accuracy than the other.

Abstract: ABSTRACT OF THE DISCLOSURE          A surgical case cart having a closed container supported on a chassis.  The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the con-tainer can be completely opened with the front and portions of the sides being exposed by the door panels wrapping around the side and back.  The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction.          The lower edges of the door panels provide a baffle effect to reduce the movement of contaminated air into the cart.          The top of the cart contains an overhang lip to prevent liquids from spilling into the container.  Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect.  The intersection between the back, sides and chassis is constructed to avoid the possibility of collecting contamination and bacteria.  A door latch is provided which indicates whether the contents of the cart are sterile or contaminated.  Opening of the cart door panels nevertheless can be accomplished without the use of the operator's hands.  The cart construction therefore provides improved sterility, greater accessibility, and brings about easier maintenance.
