Title: Circuit breaker
Inventor: LEONARD JAMES H
IPC: H01H71/52
Filed: 1982-08-25
Granted: 1985-07-09
Abstract: IMPROVED CIRCUIT BREAKER          ABSTRACT OF THE DISCLOSURE       A circuit breaker has contacts which are engageable as a result of manual operation of a toggle mechanism causing the circuit breaker to close and open when the toggle is in an erect and collapsed condition, respectively.  Subsequent opening of the circuit breaker is accomplished by either manual operation or automatic due to a current responsive latch within the toggle mechanism.  As a result of a unique movable contact biasing arrangement, more uniform pressure is obtained between the contacts and a wiping action of the contacts is obtained during closing.  The movable contact is mounted on a contact member pivoted at its center on a solid pin mounted in the breaker case through an elongated aperture in the contact member.  The elongated aperture allows for a limited degree of movement of the contact member transverse to the pivot pin.          It is this limited transverse movement which increases the tolerance range by providing overtravel of the movable contact and wiping action of the contacts.

Abstract: BALE LENGTH CONTROLLING SPROCKET FOR BALING MACHINES     ABSTRACT OF THE INVENTION         The length of a bale is normally gauged by a fixed toothed wheel engaging the top of the bale.  There-fore the height of the bale can effect the cut-off point so that bales can be of uneven length.  This device utilizes a floating gauge wheel or star wheel which therefore rota-tes at a constant speed so that its actuation point is constant.  It is connected to the knotting device which in turn controls the cut-off point of the bale being formed.

Abstract: ABSTRACT OF THE DISCLOSURE           An expansion anchor is disclosed for mounting in a receiving socket in base material to enable an object to be clamped thereto.  The anchor comprises a longitudinally split tubular sleeve to which an internally threaded expansion body is retained by means of  lugs thereof engaging slots in the body of the sleeve.  The slots are provided to permit  the tubular sleeve to expand into gripping contact with the receiving socket as the expansion body is drawn axially within the sleeve by a threaded anchor rod.  The sleeve is provided with support means for the anchor rod when in engagement with the expansion body.   The support means constitute telescopic spacer elements between the head of the anchor rod and the tubular sleeve which allow free relative movement between the expansion body and the head of the anchor rod until the  anchor  is  set  in the receiving socket.   The arrangement is such that in the set condition the spacer element and expansion body assume positions around the rod which together with the sleeve provide for solidity of structure of the expansion anchor within the receiving socket.   The expansion anchor is thus suitable for applications where high shear loads and vibrational forces are to be encountered.

Abstract: ABSTRACT OF THE DISCLOSURE           An improvement in the manufacture of cube-on-edge oriented silicon steel; the improvement comprises serrating said steel either before or after final texture annealing, whereby reduced watt loss is achieved.           Cube-on-edge oriented silicon steel in the form of sheets is known for use in various electrical applications including transformer cores.  With cube-on-edge silicon steel the alloy is characterized by secondary recrystallization in the (110) [001] position which is termed the cube-on-edge position.          This material in sheet form has the direction of easy magnetization in the direction of rolling.  In applications for this maternal, and specifically when used in the manufacture of transformer cores, the material is required to nave reduced watt loss, because the consumption of electrical energy decreases as iron loss decreases.         It is accordingly an object of the present invention to provide a method whereby in the manufacture of cube-on-edge silicon steel reduced watt loss may be achieved.         This and other objects of the invention, as well as a more complete understanding thereof, may be obtained from the following description and specific examples.         In the practice of the invention cube-on-edge silicon steel to which the invention is directed is conventionally processed by hot rolling and cold rolling with intermediate annealing.  Thereafter, the steel is subject to texture annealing to produce the desired secondary recrystallization in the (110) [001] position.  It has been found, in accordance with the present

Rectilinear movement of the dispensing head (56) along the first axis A and coordinated extending and retracting rectilinear movement of the label carrier (58) along axis B transfers a label (50) from the magazine (48) to the mold (28) in preparation for the blow molding operation.  The label dispenser (22) has particular utility when provided with a pair of the label carriers (58) to simultaneously transfer a pair of labels (50) to the open mold (28) within the con-fined space limitations involved.
