Abstract: The method of joining and sealing a wrought aluminum hot water generator with the cover and the die casting forming walls of a hot water channel wherein a weld bead is laid on top of and between the cover and the die casting. The weld bead is then compressed by a flat steel plate to squeeze out any small pockets of gas that could destroy the water tight integrity of the weld.

Abstract: An electric drip coffeemaker hot water generator wherein a unique self-cleaning water channel construction is provided in an aluminum casting. A plurality of transverse lands and grooves are formed in the walls of the water channel so that mineral deposits that build up on the lands and grooves and other surfaces of the water channel will crack off or flake away in relatively small chips from differential thermal expansion and contraction. The small chips will be flushed through the channel and into the coffee grounds.

Abstract: A vertically adjustable locking mounting arrangement is provided for a box-like structure to secure the structure, such as a drip coffeemaker, to an overhead support as the bottom of kitchen cabinetry to support the coffeemaker off the counter space.

Abstract: An electric oven toaster construction wherein a unique cam follower and rotatable cam accurately sets the threshold temperature of a thermostat switch. The rotatable cam includes relatively steep rise surfaces and the cam follower includes a generally flat mounting portion, a short blade portion and a slide portion in contact with the rotatable cam. An adjusting screw is threaded through the short blade portion close to the mounting portion. With this construction, the rotary position of the cam may be manually adjusted to accurately move the short blade portion and the adjusting screw to accurately move a thermostat switch contact only approximately one-third of the distance that the steep cam surfaces move the cam follower to accurately set the position of the thermostat switch contact to set the threshold temperature of the oven toaster.

Abstract: In a system for displaying the net distance travelled by a magnetic recording tape, the tape includes a recorded track having a periodic flux pattern. During each period, the flux pattern includes an asymmetrical pulse characterized by a flux increase during a first length of tape and a flux decrease of the same magnitude during a second and different length of tape. A single flux responsive head detects the pulses when the tape is moved and a differentiating circuit provides a pulse signal whose sense is related to the directions of travel of the tape. The pulse signal is coupled to an up-down counter which drives a display. The display indicates the net distance travelled by the tape.

Abstract: A weighing scale is provided with a multi-string system stressed in tension and vibrated at its natural frequency for determining the magnitude of a weight applied to the scale. The string system comprises two or more laterally spaced-apart parallel strings that are constrained to vibrate as a unit.

Abstract: A selection circuit for series connection between the output of the detector stage and the input of the audio amplifier. The selection circuit requires a minimum number of components and is useful to drive a tuning indicator or similar type circuit.

Abstract: The invention relates to an adjustable hair curler of general spool or roller shape with a pair of telescoping elongated tubes axially and rotatably movable relative to one another. A pair of nested larger diameter end caps is secured at each end of each tube with the roller generally resembling a spool. Each pair of caps includes a first cap with plural spiralled cam slots radiating from its center and a second cap nested in the first with a plurality of corresponding or equal number of straight cam slots radiating from its center. The nesting caps are rotatable relative to each other and the caps at each end are connected together by a plurality of toothed elongated curler segments. Each segment has structure at each end cooperating with the cap slots such that by rotating the end caps in opposite directions the segments are radially cammed to change the curler roller diameter. Additional structure locks the cap rotation at any desired roller diameter.

Abstract: A weighing scale of the household type includes a base, a platform vertically positioned above the base, and a force transmitting means therebetween. The force transmitting means includes relative large surface area planar bearing surfaces on the base and platform for mating contact with bearing surfaces on levers for transmitting force to a weight sensing means. The bearing arrangement permits substantial misalignments of scale components since the planar bearing surfaces do not establish the moment arms of the force transmitting means.

Abstract: An electric oven toaster construction wherein a unique rotatable cam controls the bake, toasting and broiling modes of the oven toaster and simultaneously sets the threshold temperature of a thermostat switch during toasting, baking and broiling. The rotary cam includes a rearwardly extending rod portion having a radially outwardly extending lobe for cooperating with a cam follower portion of a bake switch for opening the bake switch when a bake operation is set and closing the bake switch when a toast operation is set. The rotatable cam also includes a circular disc portion positioned in front of the rod portion and integrally formed therewith. The circular disc portion has a cam surface that extends rearwardly and is in sliding engagement with a thermostat cam follower blade to set the thermostat cam follower for a particular toast color.

Suitable strain gages are secured to the beam any place between the closer pair of fulcrums. The entire sandwich is held together by a deformable plastic housing that secures the plates and fulcrums together and is barb-connected to the platform. The strain gages are connected to conventional converting structure measuring the change in resistance under load and calibrated to read weight. The deformable plastic housing holding the sandwich is an integral molding with structural details reducing friction between the parts.
