Abstract: A mechanism for setting a thermostat having a housing wall forming a mounting opening. A rotatable setting shaft projects through the mounting opening and defines a circumferential groove concentric with respect to the shaft axis and a cam is fixed to the shaft for rotation therewith relative to the housing wall. The cam has a bore with at least one slot at a predetermined angular location and the shaft is locked to the cam by expanding the shaft into engagement with the bore and slot.The shaft is journaled in a bearing for rotation relative to the housing wall. The bearing comprises at least a collar-like structure fixed with respect to the housing wall and extending axially relative to the shaft and radially inwardly deformed toward engagement with the shaft groove. The collar-like bearing structure and shaft groove cooperate to enable rotation of the shaft relative to the collar-like structure about the axis and to restrain the shaft against axial movement relative to the housing wall.

Abstract: A linkage assembly for linearly moving a valve of a coupler between its open and closed positions has a yoke pivotally connected to a first link which is fixed to a rotary shaft so that the yoke rotates about the axis of the rotary shaft during a predetermined angular rotation of the rotary shaft. The yoke and a second link, which is pivotally connected to the valve, are in bearing engagement during the predetermined angular rotation. During a portion of the predetermined angular rotation, the center of the bearing surface of the second link is maintained in alignment with the axis of rotation of the shaft by a pin on the second link riding in an arcuate channel fixed to the shaft for rotation therewith.

The pressure plate member is formed integrally with the first and second members and spring-biased. The mechanism may be used for example in a doll or the like.

Abstract: A combination VHF and UHF tuner is provided in which a common station selector shaft may be rotated a number of revolutions to cover the seventy stations in the UHF band. The common selector shaft is provided with twenty-four detent positions per revolution and in alternate positions of the shaft the twelve VHF stations in the VHF band are received. As the common selector shaft is rotated through several revolutions the VHF stations are repeatedly received but are interspersed with different individual stations in the UHF band. Accordingly, no matter what UHF station is being received, all of the VHF stations are always within one turn of the common selector shaft. In many mixed UHF-VHF reception areas a single turn of the common selector shaft is sufficient to select all of the UHF stations as well as all of the VHF stations which are broadcasting in that area.

Abstract: In a pivotally mounted member of the memory fine tuning arrangement for a turret type television tuner, a pivotally moved lever plate provided integrally with a pivotal shaft having head portion, neck portion and body portion, is pivotally mounted on a front wall chassis base by setting the neck portion of the pivotal shaft into a notch of the front wall, wherein assembly of the lever plate to the front wall chassis base can be achieved by the two steps of inserting the head and neck portions of the pivotal shaft into a large opening portion of the notch in the front wall and slidingly setting the neck portion in a small opening portion from the large opening portion through continuous opening portion of the notch. To ensure easy and accurate assembly, a vertical support for the pivotal shaft on the front wall is affixed to the pivotally mounted member so that the parallel relation between the front wall and the lever plate is maintained.

Abstract: A device for interconverting linear and rotatory motions, and particularly a pressure fluid operated actuator for rotary plug valves and the like. A piston axially slideable and rotatable in a cylinder is supported by first and second sets of connecting elements which are spaced from and inclined to the axis of the cylinder. Each element of one set is pivotally connected at one end with a fixed member and at the other with the piston. Each element of the other set is pivotally connected at one end with the piston and at the other with a rotary output element, for example, a shaft. Axial movement of the piston is translated into rotatory movement of the output element by pivotal action of the connecting elements. The connecting elements of the first and second sets extend from the fixed member to the piston and from the piston to the output element in opposite circumferential directions.

Abstract: This invention relates to a channel selector suitable for use in a television receiver set. The channel selector comprises a channel selecting shaft which is linked to a variable capacitor shaft through an Oldham coupler. A fine tuning shaft also is linked to the variable capacitor shaft through a coupler incorporating an incremental detent arrangement.Selection of a channel is made by turning the channel selection shaft to move the variable capacitor shaft by a suitable angle (for instance, about 2.degree.). When the channel selection shaft is turned by such an amount, the coupler slips so as to allow the variable capacitor shaft to turn independently of the fine tuning means. Once a channel is selected, fine tuning is made by slightly turning (for instance, within 0.3.degree.) the fine tuning shaft to correspondingly rotate the shaft of the variable capacitor.The channel selector also comprises means for memorizing the results of the fine adjustments for individual channels.

Abstract: Disclosed is an auxiliary mechanism for rapidly imparting rotational energy to electrical switch components. An insulator connects an electrical switch component to an output shaft mounted for rotation in the mechanism housing. A lever arm assembly is mounted on the shaft and a link member is pivotably connected between the lever arm assembly and a first arm extending from a bellcrank member. The bellcrank member is mounted for rotation in the housing and has a second arm that is operably connected to one or more solenoids. Initially the link member and first arm are in an overcenter toggle position so that the insulator cannot be accidentally rotated. Energization of the solenoid causes rapid rotation of the insulator because the mechanical advantage of the system in such that maximum force is applied initially.

Abstract: A UHF television tuner utilizes a mechanical fine tuning mechanism that alters the operation frequency of the oscillator of the tuner independently of the position of the main tuning shaft. The mechanical fine tuning mechanism utilizes a tuning slug disposed inside a tunable coil of the oscillator, and a rotary to linear motion translating mechanism is disposed within the fine tuning shaft for converting a rotational motion of the fine tuning shaft to a linear motion of the slug inside the coil.

Abstract: A detent type tuning mechanism for a UHF tuner having a continuously variable tuning shaft includes a detented selector shaft, a gear train interconnecting the tuner shaft and the selector shaft, and a memory type fine tuning mechanism including a rotatable turret having mounted thereon a plurality of cams each engageable by a fine tuning shaft when the selector shaft is positioned in predetermined ones of the detent positions. Each cam serves as a memory fine tuning system for a predetermined group of adjacent UHF channels. A cam follower interconnects one of the cams and the tuning shaft, and serves to rotate the tuning shaft in response to the rotation of one of the cams by the fine tuning shaft. An indicator dial provides a numerical display of the precise UHF channel selected at each position of the detented selector shaft.
