Title: Click-free harmonic generating circuit - adds harmonics to input frequency using swept delay line for electronic musical instrument
IPC: G10H1/10
Filed: 1984-06-28
Abstract: The single frequency input signal (1) is fed to a delay line circuit (2). The delay line has a number of tappings (4.1. to 4.N.) equispaced in terms of time units (t). A selector circuit (5) selects each tapping in turn, to be fed to one input of a multiplier circuit (7). The selector sweep is s controlled by the output (12) of a control circuit (11), which also supplies the other input to the multiplier (7). If the sweep is (10) from the longest to the shortest delay, the multiplier output (8) is at a higher frequency than the input (1). If the sweep is reversed, the output frequency is lower. Other versions produce different harmonic signals including the so-called chorus effect.

Title: Trilevel sandcastle pulse encoding/decoding system
IPC: H03K5/00
Filed: 1984-12-12
Abstract: A color TV receiver is provided with an encoding/decoding system for a trilevel sandcastle pulse train, exhibiting a middle pulse level during recurring kinescope bias control intervals, and comprising excursions between a base level, a low pulse level, and a high pulse level during periods outside said kinescope bias control intervals. The system's decoder includes a trio of voltage comparators for comparing incoming sandcastle pulses with respective reference voltages derived from three different intermediate points on a common voltage divider connected across the terminals of a DC supply. The system's encoder includes keyed means for determining the middle pulse level of the trilevel sandcastle pulse train in accordance with the output of a second voltage divider connected across the same DC supply as the first voltage divider. An output of a third, selectively enabled, voltage divider, connected across the same DC supply as the first and second voltage dividers, is determinative of said low pulse level. The third divider is subject to modification during base level appearances, with the base level determined by the third divider's modified output during the periods of divider modification. During high pulse level appearances, the third voltage divider is disabled to establish the high pulse level at or near the full output potential of the DC supply.

Title: Process for the manufacture of insecticidal pet collars by means of co-extrusion of multi-components
Inventor: CORRIGAN EUGENE JAMES
IPC: A01K27/00
Filed: 1985-10-14
Abstract: 57 Co-extruded insectidical pet collars contain one or more active insecticidal components in a desired relationship to the skin of the animal. The outside layer (away from the skin) contains carbamate, organo-phosphate chlorinated hydrocarbon or other insecticide that is irritating to the skin, or a cholinesterase inhibitor. The inside layer acts as a barrier to the insecticide. The layers of a multi-layered collar which is prepared by extrusion may also contain different insecticidal systems. A co-extruded collar is prepared by preparing two blends which have varying concentrations of active and/or inert ingredients, depending on the end product which is desired. Each of the blends is fed into an extruder wherein the polyvinyl chloride is fused. The melt blend from extruder B is then transferred to the die of extruder A where it becomes an integral part of the extruded strip from extruder A.
