Inventor: HAZEN JOHN C J M
IPC: C09J201/00
Filed: 1992-06-11
Abstract: A process for the production of a stabilized rosin and a stabilized rosin obtainable by the process. According to the process rosin is heated in the presence of a phosphoric acid or a strong acid in combination with a phosphate containing substance and disproportionated by addition of iodine. Preferably the rosin is first heated in the presence of the phosphoric acid or the strong acid in combination with the phosphate containing substance and thereafter disproportionated by the addition of iodine. Iodine is preferably added in at least two steps and the disproportionation is allowed to proceed between each step. The stabilized rosin can be used as a tackifier resin in adhesives and as a sizing agent for paper, paper boards and similar products.

Abstract: An analog-to-digital converter comparator circuit includes a pair of differential amplifiers (10, 18) having their outputs normally intercoupled in a subtractive sense. At a sampling strobe time, the output of one differential amplifier is reversed such that outputs of the two differential amplifiers are additive. The period of time during which the output signals add can be made as short as desired, for example by successively operating differential coupling circuits (26, 28, 38, 44) at the amplifier outputs through an intervening delay line (50). A very small aperture time is secured which is substantially shorter than the time constant of subsequent circuitry. A latch circuit (60) receives the output of the comparator for assuming one of two different states in accordance with the comparator sampled output.

Abstract: There is disclosed an inbound/outbound call handling system and method in which outbound calls are automatically paced so that as attendants become available a valid call is completed to be handled by the available attendant. As an inbound call is received, the system responds by halting attempts to place an outbound call and queueing the inbound call for handling by the next available attendant. The system takes advantage of an algorithm which statistically monitors average call completion time, average attendant in-use time, average time to answer and probability of a valid answer. Call placing and receiving overlap is controllable in conjunction with the monitored statistical parameters to achieve operation around any desired system operating parameter. The system is controlled by a plurality of precisely defined operational tasks operating in a hierarchical manner.

Abstract: A bar code printer capable of printing bar codes simultaneously with character strings made of, for example, alphanumeric characters. Operating a bar code key causes a bar code input display to appear on a display and the bar code start code to be stored in a bar code buffer. Then operating a number key causes a number code representing the number to be stored in the bar code buffer and a dot pattern representing the number code to be output to a video RAM. Operating an execution key while a 13 digit number code is stored in the bar code buffer will additionally cause an end code to be stored in the bar code buffer and the resultant code string to be stored in a text memory.

Abstract: Horizontal or vertical parabolic waveforms corresponding to arbitrary aspect ratios are generated with a relatively small number of memory devices for storing data values which are used for generating parabolic waveforms to compensate horizontal or vertical deflection distortion in television receivers. 
     A first and second memory device which each store data values for generating parabolic waveforms necessary for the images of a specific aspect ratio (for example, (4:3) and (16:9) are provided. When a desired aspect ratio is given to a logic circuit, two coefficients are calculated in a coefficient arithmetic logic unit and the outputs of the first and the second ROM memory device are allocated proportionally in a logic circuit. The output data values of the logic circuit are then converted to a desired parabolic waveform.
