Abstract: A machine tool has a rotatable table with a plurality of lock plates located on the underside thereof at circumferentially spaced locations, and a geneva drive mechanism arranged to coact with the lock plates in rotatably indexing the table. The lock plates are shiftable with respect to the table by means of cooperating pairs of rotatably adjustable eccentric pins. Machine screws releasably fix the lock plates at selected positions of adjustment. The lock plates are shifted and releasably fixed from above the table.

Abstract: A garment marking machine includes a lower marker-supporting track supported by a base plate, and a garment-supporting plate positioned and supported above the lower track. An upper marker-supporting track is positioned above the garment-supporting plate by means of posts that extend upwardly from the base plate and through the lower track and the garment-supporting plate. Marker assemblies positioned along the upper and lower marker tracks are used to mark garments processed by the garment marking machine. A marker assembly utilized in the garment marking machine includes a marker cap having a bore, a marker having a marking end disposed through the bore of the marker cap such that only a portion of the marker extends beyond the marker cap, and an adjusting rod operative to move the marking end of the marker through the bore of the marker cap. The bore of the marker cap is sized to tightly hold the marking end of the marker.

Abstract: A laser beam levelling instrument has a pipe length which is vertically and centrally mounted in the cover of a casing. The ends of this pipe length are pivotable, so that it can always be held in the vertical position. For this purpose two spirit levels are arranged at right angles to one another on a plate fixed to the lower end of the pipe length. The fluid in these levels is electrically conducting and the levels have electric contact points for operating a respective electric motor. The electric motors are provided with eccentric shafts which come into contact with the circumferential surface of the pipe length. If the pipe length diverges from the vertical, then the current from batteries ensures that it is brought back into the vertical position by means of the eccentric shafts. A laser light source is located in the lower part of the pipe length and a further pipe length is inserted in the upper end of the pipe length and can be rotated by a third electric motor.

Abstract: A three-axis control for precisely and conveniently adjusting items such as irrors and lenses is disclosed. The adjuster apparatus includes a vertical stack of three rotatable adjusters. Rotation of the first effects vertical translation, whereas the second and third are eccentric assemblies which interact to effect movement along two angled axes perpendicular to the vertical axis.

Abstract: Surgical knife with controllably extendable blade, the blade retained by a blade holder extending through an axial opening in the knife body and connected with a member threadedly retained within the knife body for axial adjustment and also connected to an adjustment knob at the rear end of the knife. Another feature of the knife is a foot configuration which facilitates precise use and control of the knife. Preferably the invention also comprises the knife, as disclosed, in combination with a gauge for visually inspecting blade projection, the gauge indicator consisting of a pair of eccentric circles or portions thereof, the blade projection being measured by comparison with the radial distance between the two circles.

Abstract: The measuring device comprises a body (1) whose end (1a) is secured to a rod (2) connected to a measuring instrument. A probe assembly (3,4,5) is provided with a feeler head (4a) and is secured to a lever (6) which rotates around a pin (8) in the body (1). The angular path of the lever (6) is limited by a stop (12) built into the body (1) and by a stop adjustable by means of an eccentric part (11a) in such a manner that the body (1) always takes the same position in each measuring direction on alternate measuring of two opposite surfaces lying in the same plane. A spring (9) urges the lever (6) towards its upper position. By this means, the measurement of the distance between opposite surfaces requires no calculation, i.e. addition or subtraction of measuring constants, thus making measurement easier and precluding errors in calculations.

Abstract: Method and apparatus for measuring the nip clearance between two rolls rotating close to each other. First and second members are non-rotatably mounted on opposite sides of the nip. Each member has a pair of wheels mounted so that one wheel rotates in contact with only one roll and the other wheel rotates in contact with only the other roll. The nip clearance is a function of the distance between the two members.

Abstract: An arrangement for the electromechanical measurement of the axial clearance of rotating elements, particularly for the measurement of the axial clearance of shafts in high-speed turbomachinery, in which the extended shaft of a drive motor extends substantially perpendicular to the rotational axis of a rotating element and is thereby arranged in parallel with the measured object. The shaft is provided with an eccentric feeler at an end located proximate the measured object so that, at a movement of the eccentric feeler towards the measured object, a contact signal is generated by a contact resistance responsive to falling below of a resistance threshold value between the electrically insulated eccentric feeler and the measured object as measured by an indicator. Concurrently, the instantaneous indicated value of an absolute angle-measuring encoder is stored, and the drive motor controlled so as to reverse the direction of rotation of the shaft into its zero position.
