Abstract: ABSTRACT OF THE DISCLOSURE         A method for preheating steel scrap by exhaust gas from a steelmaking electric furnace, which comprises: directing, when manufacturing steel from steel scrap in an electric furnace, exhaust gas produced in the electric furnace to an exhaust gas combustion chamber provided along a discharge duct for the exhaust gas, to combust carbon monoxide contained in the exhaust gas to form combustion exhaust gas; and selectively directing part of the combustion exhaust gas into at least one scrap preheating chamber provided along a branch duct branching off from the discharge duct to preheat steel scrap charged in the scrap preheating chamber to a predetermined temperature.  The method being characterized by:  feeding back all of the combustion exhaust gas after preheating the steel scrap charged in the scrap preheating chamber to the exhaust gas combustion chamber to combust any incomplete-combustion products which are produced by the incomplete combustion of combustible sub-stances entrapped in the steel scrap and which are contained in the combustion exhaust gas.  The method has the advantage of reducing pollution.  A method of controlling the preheating of the steel scrap at a constant level irrespective of variations in the temperature of the combustion exhaust gas is also taught.

Abstract: TITLE:  TOY HAVING PLURALITY OF PARTS CAPABLE OF         DISENGAGING UPON ROTATION                  ABSTRACT       A toy has a first member which includes a rotating mechanism at least a portion of which is capable of rotating with respect to the first member about an axis of rotation.  A second member is capable of being associated with the first member and being rotated with respect to the first member between a first position wherein the second member is stable with respect to the first member and is supported by the first member and a second position wherein the second member is desta-bilized with respect to the first member and is capable of becoming dissassociated from the first member.  A coupling mechanism detachably couples the second member to the rotating portion of the rotating mechanism so as to transfer rotary movement of the rotating portion of the rotation mechanism to the second member to rotate the second member with respect to the first member between the first and second positions.  The second mem-ber and preferredly a plurality of other members are stacked on the first member and when the second member is caused to rotate with respect to the first member it and the plurality of other members become dislodged from the first member.

Abstract: NOZZLE FOR HAND-HELD VACUUM            ABSTRACT OF THE DISCLOSURE         A portable vacuum cleaner having a nozzle extending from the housing and a dust bag supported within the nozzle.  The nozzle consists of two longitudinal sections one of which is an extension of the housing and the other of which is removable, to permit insertion, removal and replacement of the dust bag, and may also be locked in position.  To lock the removable portion of the nozzle, there is a retainer for the housing end of the removable section and a tubular member which has a modified breech block type of locking flange at its front.  The inner portion of the tubular member supports the dust bag in the nozzle.  The locking flange is placed on a tab extending from the section of the nozzle which is an extension of the housing and receives a tab from the removable section of the nozzle.  The locking flange is then rotated to effect the lock at the front end of the nozzle thereby locking the tubular member into the front end of the nozzle and locking the removable section of the nozzle in place.  An end nozzle is provided having an opening communicating with its own tubular extension which is a removable fit into the tubular member which carries the locking flange.  The end nozzle has an apron which covers the front end of the nozzle to cover the locking flange and present a smooth appearance.

Abstract: Abstract of the Disclosure A Mechanism for reversing the direction of rotation in a drilling apparatus comprising a feeding beam (1) and a drilling machine (3) supported by the beam for longitudinal movement back and forth along the beam in a drilling direction (A) and an opposite re-turn direction (B) by means of a feeding mechanism (4). The drilling machine is provided with a pressure medium driven rotating device (9) for rotating a drilling rod and with a reversing valve (13) con-nected to the pressure medium system of the rotating device. The reversing valve is provided with a spindle rotatable between two positions in which the rotating device rotates the drilling rod in opposite directions. The reversing mechanism comprises two actuating elements (24,27) rotatable with respect to each other. One element (24) is in rotational engagement with the spindle and is moved axial-ly together with the spindle at least at the end of the return direction of the drilling machine. The other element (27) is arranged to maintain non-rotating and stationary by means of a fixed stop (31) in the feeding beam at the end of the return direction but to rotate and move axially with respect to said one element at the beginning of the drilling direction. The actuating elements are coupled to each other by means (28,29) which force said one element to rotate with respect to said other element when the elements move axially with respect to each other and thereby to rotate also the spindle to a position causing a reversal of the direction of rotation of the rotating device.
