Abstract: A programmer for an appliance having a line power switch and a plurality of program switches sequentially actuated by a cyclic cam mechanism. The program switches are latched to the actuated condition and uplatched independently of the cyclic mechanism by electrically energized release mechanisms, individually controlled by an electronic controller having a microcomputer which employs a user selected programmed sequence.

Abstract: A compression type load cell (50) is provided for measuring a load (L) applied to an object (3). Cell (50) has a first end (7) adapted to receive load (L) thereupon and an opposite end (9) adapted to support cell (50) upon object (3) with end (7) adapted to direct load (L) axially along a central longitudinal axis (x) of cell (50). Cell (50) has a reduced section (8) having a first pair of bores (14,14') therethrough that are preferably oriented substantially transverse to axis (x) and are spaced-apart from each other substantially symmetrically on opposite sides of axis (x). Reduced section (8) has a second pair of bores (16,16') therethrough between bores (14,14') and end (9) that are preferably substantially transverse to axis (x) and respectively axially aligned with bores (14,14').

Abstract: A plurality of load bar assemblies (14) are connected between a supported structure (10) and a supporting structure (12) for determining an amount of load in the supported structure. Each load bar assembly includes a load bar (20) having a middle portion (22) connected with the supported structure and end portions (24, 26) connected by load bar mounting assemblies (34) with the supported structure. Each load bar mounting assembly includes a fulcrum member (50) which supports the load bar end portion on a fulcrumming surface (54). An elongated connecting structure (60) having an enlarged upper portion (64) extends through a load bar end portion aperture (32) and a fulcrum member aperture (56) and is connected with the supporting structure. An annular washer (72) and a tubular sleeve (74) of resilient material are disposed between the elongated connecting structure and the load bar end portion to allow limited movement therebetween.

Abstract: A spark electrode assembly (10) for a gas range igniter system is disclosed which is low in cost, easy to assemble, and reliable in operation. The assembly comprises a resilient, electrically conductive support member 18 having a U-shaped configuration and adapted for connection to the top frame of the gas range. An integrally molded insulator member (46) is connected to the support by means of a peripheral flange portion (50) which extends through rectangular openings (38) formed in parallel leg portions (43, 44) of the support. The inward spring bias exerted by the legs of the support maintain the insulator assembled thereto. A barbed, wire connecting insert (60) is crimped to an electrical lead (58) and inserted into a bore (54) in the insulator. Barbs (64, 66) on the insert abut against the top surface of a wall (56) which extend inward radially from the internal wall of bore (54) and prevent removal of the electrical lead from the insulator.

Abstract: A liquid level monitoring system functions by applying an alternating voltage to a probe. When the liquid level in a reservoir touches the probe, a low impedance to ground is present, thereby permitting current to flow to ground. When the liquid level falls below the probe, a high impedance to ground is created and current flows to a detector. The detector switches on an alarm which flashes an appropriate warning.

Abstract: A transducer is mounted on the boom to produce an electrical signal proportional to the angle the boom has moved in a horizontal plane. A resistance related to the boom length receives the output of the transducer and supplies a current proportional to L Cos .theta. where L is the boom length. A potentiometer supplies a current proportional to the offset distance from the boom hinge point to the rotating axis of the crane and an indicator means receives the current proportional to both the L Cos .theta. and the offset distance for indicating the operational radius of the crane.
