A method for adjusting the resistance of cylindrical layer resistors comprising utilization of a laser beam. The resistor is rotated about its longitudinal axis at a predetermined rotational speed. Simultaneously therewith, a pulsating laser beam is moved at a predetermined linear speed along a line parallel to the longitudinal axis of the resistor element. The resistor rotational speed is preferably an integral multiple of the linear speed of the laser beam. The impulse time (t) of the laser be...

Lateral stabilizing supports for a ladder which are secured to the ladder by a pair of horizontal braces which extend through hollow rungs for added strength and means for modifying the length of one of the legs of the ladder as well as the supports to compensate for irregularities in the surface upon which the ladder is standing. A simple, quick acting locking arrangement is provided for locking the adjustable legs in their operative positions.

The present tool holder, for use in adjustably supporting a cutting tool, makes use of the same element and slide-face both for adjusting the holder in a first direction and for adjusting the holder in a direction perpendicularly oriented thereto. One support surface abuts against a cylindrical surface whilst another support surface abuts against a movable adjusting-supporting member in the tool body.

An adjustable bushing with provision to control the degree of fit between the rotating shaft and the bushing, including provisions to take up slackness caused by wear. The bushing member is in the form of a helical spring mounted in a tapered housing, said bushing member being keyed to prevent rotation in the external hole in which it lies. An adjustable tapered compression member applies radial pressure to the bushing in the tapered housing, with an increase in such pressure acting to both prop...

A self adjusting elevator, especially for use in a storage cabinet, or the like, which has a recess in which the elevator is horizontally disposed and within which the elevator is vertically moveable in conformity with the weight carried thereby. The elevator according to the present invention has a spring device incorporated therein which maintains tension on cables which support the elevator. As the elevator is unloaded, by removing articles therefrom, the elevator rises in the recess of the s...

An automatic adjusting device for a bicycle brake exerted by stretching a control cable comprising an outer cable and an inner wire, which is adapted to be provided at the retaining side of the outer cable thereof with an adjusting member, at the retaining side of the inner wire with an actuating member, and between both members with a clutch spring so that the length of the outer cable relative to that of the inner wire may automatically be corrected.

In a thermostat which comprises a first housing portion accommodating a circuit breaker and a second housing portion accommodating a snap action temperature sensor coupled to the circuit breaker by an actuating member, the two housing portions have mutually contacting camming faces shaped and arranged in such a manner that a coaxial rotation of the two housing portions with respect to one another varies the axial distance between the two housing portions and thus the distance between the snap ac...

An adjusting device for setting knives on wood heads. A housing with arcuate shaped legs rests on the planer drum and a movable electrical contact member mounted on the housing is set to a preselected distance from the surface of the planer drum corresponding to the desired height of the knives. A battery powered light is mounted on the housing and is electrically connected to the contact member and is energized when the blade is moved into contact with the contact member thereby visually indica...

An adjusting device for brakes, especially for rail vehicles, in which at least one support with a brake lining is arranged on a brake lever which is pivotable about a turnable shaft on a brake bridge or brake saddle or the like, while a return spring is connected on one hand with the above mentioned shaft and on the other hand with a part, that is stationary relative to the brake lever. The device also includes a slip clutch connecting the shaft to the brake lever, and furthermore includes firs...

The relay contact adjusting arrangement of this invention involves the positioning of the header assembly and motor assembly of the relay in a fixed spaced relationship prior to final assembly, with the fixed and movable contacts in opposed pairs, and associated with an optical comparator so that enlarged images of the opposed contacts can be seen, after which adjusting tools are used to bend the supports of the fixed contacts for adjusting the spacing successively for each opposed pair of conta...
