Abstract: A vehicle turn signal indicator control system for left and right turn signals in which the turn signal lever has three positions, on, off and intermediate. The system has circuitry that controls the number of pulses flashed by the left or right indicator lights when the signal lever is in intermediate position and automatically returns the lever to its off position after the predetermined number of pulses have flashed.The system includes a turn signal lever, a dip switch with at least two dual position toggle switches and control circuitry for energizing the signal indicators based on the position of the turn signal lever and the toggle switches.

Abstract: A marker for gravesites is provided with an identification holder which has two oppositely located parallel channels of different depth, the transparent shield having opposite edges received in each of the channels and a spring located in one of the channels for engaging the shield to urge the shield fully into the opposite channel.

Abstract: There is disclosed an antifriction assembly of relative moving machine elements such as shaft and thrust bearing or screw and nut assemblies having engagement surfaces formed of materials characterized by a coefficient of friction which is inversely dependent upon compressive loading. Typical of such materials are plastics such as fluorocarbons, polyamides and/or acetal resins. The antifriction assembly utilizes the aforementioned characteristics of these materials to achieve minimal force and wear and maximum life. The shaft and thrust bearing assembly comprises a shaft having a grooved land to receive a bearing plate which has a slotted aperture to capture the shaft. The shaft and bearing are formed of the aforementioned plastics. The screw and nut assembly comprises members that are also formed of the aforementioned plastics.
