The invention relates to a device for the relative adjustment of an envelope and a cap of a filament lamp by means of an optical system with which a reproduction of the filament of the lamp is projected on photoelectric cells. According to the invention the optical system comprises a number of bundles of light conductors which with their one end communicate with the photoelectric cells and with their other end debouch into a screen on which the filament is reproduced.

An adjusting unit for producing stored, selectively adjustable working voltages for control and tuning elements, more particularly varactors, comprising variable strip resistances for operation in a voltage divider circuit, said variable resistances being combined into a component, mutually releasable operating elements being mounted on the adjusting unit, said voltage dividers having wiper contacts selectively connectable to a contact rail and being adjustably movable along a track for varying ...

A mechanism is provided for varying the distance between a detector and a measuring crystal in an X-ray spectrometer. The crystal is arranged on a rotatable shaft and the detector is arranged on an arm which can perform a circular movement about the crystal shaft. The crystal shaft and the detector arm are coupled so that a rotation of the crystal shaft through an angle .theta. is accompanied by a rotation of the detector arm through an angle 2.theta.. A first pulley having a radius r is mounted...

To adjust the relative positions of two elements mounted for guided sliding relative motion in a first direction and in a contact plane thereof, a cylindrical adjusting tool is fitted into a reference bore in one element and rotationally and non-slippably engaging an edge of the other element. A manually operable button on the tool may be depressed to remove a cam permitting adjustment rotation of the tool, or released to secure the tool in the bore while clamping means are operated integral wit...

A mechanism for adjusting a member in three degrees with respect to a reference plane comprising three screws with spherical underheads extending through the member and threadably received in a base plate, springs about the shanks of the screws bias the member upwardly while the spherical underheads make at least full fine circular contact in recesses from the upper surface of the member.

Adjusting device for a hoisting crane including a work spindle, which is given an axial travel within a cylinder by a relative movement between a screw and a cooperating groove following a driving device. The work spindle has a free end, which is connected to a lifting arm of the hoisting crane through a connector or the like. In order to make it possible to move the work spindle axially without help of the driving device in the case of an emergency, the connector includes a connection which is ...

An adjusting mechanism for a jaw of a ski binding. The adjusting mechanism includes a holding plate which is fixedly secured to the upper surface of a ski. A base plate for the ski binding component is slidably disposed on the holding plate with locking means being provided to lock the base plate to the holding plate. That is, structure is provided for preventing the base plate from lifting off from the holding plate and locking structure is provided to prevent relative longitudinal movement the...

An adjustable resistance comprising a box-shaped body including an upper wall having an elongated slit and a bottom plate provided with a resistance element and a conducting element on the inside surface of the bottom plate, a fixed insulating plate being located beneath the upper wall of the body and having an elongated slit substantially aligned with said elongated slit in that upper wall, a movable insulating plate and a spring member both having registering apertures, a sliding contact suppo...

A tool for automatically adjusting the required slack in umbilical cables for their separation from a missile in a launching shell using spring actuated cable retractors and consists of a flat bar having notched, oppositely turned end portions. The tool is inserted over the explosive nut assembly at one end, the other end engaging the wire cable separation rope which is attached to the cables and to the retractor. By taking up the slack of the cables until the wire rope engaging end of the tool ...

A packframe for hikers is constructed using side and cross-members rigidly held together by tension created in straps wrapped around the frame. The packframe has shoulder straps anchored at both ends to substantially a common point near the bottom and out from the general load bearing area of the packframe. A belt is coupled near the bottom of the packframe to absorb a portion of the load and to stabilize the packframe.
