Abstract: Abstract of the Disclosure A duplicated switching system including a number of communication units wherein each digital word transmitted by an originating communication unit is conveyed via both of the duplicate time-multiplexed switches in the system and a destination communication unit autonomously selects the digital words to be used for further communication based upon whether the word error check portions can be derived from the word information portions.  Advantageously, the system continues to operate in the presence of system faults not simultaneously affecting digital words from both time-multiplexed switches without any erroneous words being used for further communication and without involving a system central control.

Abstract: ABSTRACT OF THE DISCLOSURE     IMPROVED OVERCOAT FOR OPTICAL RECORDING MEDIA        This disclosure concerns protective overcoatings for an information storage record which  includes  an information-layer adapted for optical data recording.  The protective overcoatings  are  transparent  to  recording radiation and especially adapted to enhance service life and recording characteristics.       A typical  coating comprises the polymerization product of a formulation including at least one "bulk resin"  (e.g.,  an acrylamide or an acrylate monomer or pre-polymer),   plus   an   associated  non-yellowing photo-initiator, and a non-yellowing adhesion-promoter.       Once applied, this coating is cured by exposure to UV radiation  so  as  to  cure  it without heating it significantly so that said radiation functions as the sole or principal polymerizing agent, acting quickly, and with little or no supplemental heat,  and without extended "tackiness".   This formulation will readily "level" to enable  the desired  coating  to  serve  as  a mechanical/chemical barrier.

Abstract: SEED COATING COMPOSITION AND METHOD            Abstract of the Disclosure A novel coating for crop seeds is dis-closed which serves to delay germination of the seeds after planting thereof for significant periods of time (such as over the winter months), and there-after allows germination and plant development in the normal manner.  The preferred seed coatings include a relatively rigid, dried residue of a synthetic resin (e.g., an epoxide) which is filled with a material such as a hydrate former which slowly reacts with moisture from the earth and expands, so that the resin coating will rupture and allow seed germination when soil and climatic conditions are conducive to plant growth.  It has also been discovered that a preferred precoating comprising methyl cellulose serves to enhance plant growth and hardiness, particularly in the period shortly after emergence.

Abstract: POSITIONED CHIP SURFACE COVERING                         Abstract The present invention relates to a process for preparing chip-containing decorative surfaces wherein the chips are positioned so as to provide a pattern.  A first adhesive material is selectively applied to a support surface and the conditions are adjusted so that the first adhesive material is substantially non-adhesive in nature.  A second adhesive material is selectively applied as a pattern on top of or adjacent to the first adhesive material and chips are applied to the surface so as to be adhered by the second adhesive material. Any non-adhered chips are removed and the conditions are adjusted so that the first adhesive material demon-strates adhesive properties.  A second type or color of chip material is then applied so as to be adhered by the first adhesive material.  Upon removal of the non-adhered chips, a product is obtained having a positioned chip pattern.  The process may also be practiced using additional adhesives and chips so as to provide products having more than two types of positioned chips.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for transmitting paging and absolute time information to, and receiving such information at, a remote portable electronic timepiece and pager unit during a short time slot assigned to the pager unit is disclosed.  In the pager unit, an oscilla-tor is coupled to a timer which produces a time display. These functions are constantly powered.  The timer per-iodically causes power to be supplied to a receiver and message decoding components of the pager unit during a short time slot in which transmitted data is to be re-ceived.  The receiver detects and reconstitutes a trans-mitted signal.  The transmitted signal is processed through a decoder which extracts paging and time update data.  If the paging data includes the pager unit's ID number, the unit indicates that a page has been received. The time update data extracted from the transmitted signal is used to synchronize a timer in the pager unit. The timer provides an accurate time indication for the watch function.  The same timer additionally determines when power is supplied to the pager unit's receiver and message decoder components so that they will be powered during the short time slot.
