Abstract: This disclosure concerns a new and distinct variety of Acer saccharum, commonly known as sugar maple tree, characterized by a symmetrically shaped head at a very early age, not seen in the usual sugar maple tree, with a straight leader, an abundance of branches and a vigorous and hearty growth habit.

Abstract: The system comprises a frequency number memory device for storing information regarding the frequencies of respective tones, a keyboard switch for reading out frequency number information corresponding thereto from the memory device, an address generator including an adder for adding a predetermined number of the frequency number information thereby producing an address signal consisting of plural bits, address composers for processing the bits of the address signal and thereby composing digital tone signals constituting a saw-tooth, square and triangular waveshape, and digital-analog converters for converting the digital tone signals into analog tone signals, which are thereafter used to synthesize waveshapes of any tone.

Abstract: A telephone card index, having a switch connected to the card finder for initially locking on to a memory section of a miniprocessor.[., a.]..Iadd.. .Iadd.A .Iaddend.key aligned with each name line of the card locates the exact memory address of the number to be called with pre-recorded dial signals at the memory address for an individual name line, .[.permits.]. .Iadd.permitting .Iaddend.automatic telephone dialing of the selected number. A keyboard in the circuit, with a display.Iadd., .Iaddend.permits adding, changing or recalling the recorded number at each address.

Abstract: The disposable lid for a coffee cup or the like has penetrable score lines around the sides of a 90.degree. sectorial portion thereof for easily breaking off this portion to form a drinking access opening therethrough while the remaining portion of the lid serves to reduce the danger of spilling the contents of the cup when held in an unsteady cup support environment. Another penetrable score line extending near the periphery of the lid, between the sides of this sector, and a fold score line between the ends of this peripheral score line provide for a segmental flap to be broken open and bent on the fold score line to form an access opening to the contents of the cup while providing a substantial shield against spilling the contents of the cup through the opening.

Abstract: Multibit digital signals, being telephone call signal samples from different simultaneous call connections and coded in an ordered coding system, are stored in different locations of a first buffer store. The respective signals are coupled through a stored program controlled switching processor to randomly selectable locations of a second buffer store for transmission to corresponding respective different call destinations. A register is provided in the switching processor for temporarily storing each signal as it is coupled through the processor. Also included in the processor is the capability for additional selectable processing of those coupled signals en route.
