Abstract: Abstract of the Disclosure An elongated building structure comprises a plura-lity of building elements, some of which constitute end elements. Said elements,which may be considered as being comprised in a building set, have a uniform thickness and generally a uniform, constant length and a uniform, con-stant height. To make possible construction of building structures which are elongated, i.e. have a greater exten-sion than the elements proper, these are devised with specially designed connection ends provided with notches. The connection ends of two building elements are inter-connected by means of special connection elements which extend in the transverse direction of the building ele-ments and are also provided with notches into which portions of the connection ends of the building elements engage. These ends are in their turn engaged from the outside by those portions of the connection element which are located on opposite sides of the notches of the connection elements.       The building structure according to the invention can be erected without the utilization of screws, nails, bolts, nuts and the like and be made full size or may con-stitute a toy model.

Abstract: ABSTRACT A borehole probe for use in analysing or carrying ground using non-disposure x-ray fluorescence is described.  A Co-57 radiation source is housed within a shield which defines with another shield a conical collimator which directs primary radiation to the surrounding earth.  A detector is shielded by the other shield from direct radiation from the source.  The other shield is formed in two parts, a top conical part and a bottom cylindrical part which has a window for permitting secondary radiation arising in the ore-bearing surround earth to pass to the detector.  The source and detector can be moved axially towards and away from each other to achieve a desirable angle of backscatter. The source and detector can he located very close to each other so that this angle approaches 180° which is the optimum angle.

Abstract: ABSTRACT OF THE DISCLOSURE A method and device for the prevention of and the treatment for epicondylalgia externa, popularly known as Tennis Elbow, is disclosed.  The method involves the absorption and dissipation of the vibrational shocks caused by the off-centre hitting of a tennis ball during pronation and supination of the wrist   The device employs a vibration absorbing pad covering either the extensor or flexor muscles of the forearm.  The pad is tightly located against the said muscles by means of an elastic tube from the wrist area to the elbow.  An elastic strap, located outside the aforemen-tioned tube around the largest diameter of the forearm and fastened by Velcro or like fasteners, is an additional means for maintaining the pad in close contact with the arm surface. The aforementioned pad, shaped to conform with the extensor or flexor muscle in the forearm, is filled with a viscous fluid or semi-fluid which will flow enough to maintain a close contact with the muscle from wrist to elbow.  The viscous fluid absorbs the surface vibrations caused by the off-centre striking of a ball with a racquet.  These vibrations are normally conducted along the extensor or flexor muscles of the forearm and are a direct cause of the inflammation of the elbow itself.

Abstract: ABSTRACT OF THE DISCLOSURE     Opposed parallel supporting rollers of a log receiving and turning assembly are rotated in order to rotate the log received thereon.  The rollers are carried by a same which is lifted or lowered, as desired, and a bar between the rollers is titable so as to lift selectively one end of the log or the other.  By such an arrangement the log is oriented so that a pair of dogs engage the log from opposite ends.  These dogs are carried by an overhead carriage assemblies which ride on tracks and are movable with respect to each other by means of hydraulic cylinder.  One dog is rotatable by a motor through 90° so as to orient the log.  The carriage assemblies are movable in a longitudinal direction so that a pair of saws, driven by motors, will simultaneously cut the logs on opposite sides so as to deposit the boards, when cut from the log, on respective conveyors which carry the boards longitudinally away from the saws.  The saws are adjustable laterally for different widths of log.  The conveyors pivot for selective feeding to one or the other of parallel discharge conveyors.  The cant is discharged by a central conveyor.

For centering said lens the peripheric zone comprises two stabilizing bosses which are disposed on the horizontal stabilization axis of the lens.  For large palpebral openings it may be preferable to use two pairs of bosses, whereby each pair comprises two bosses, disposed symmetrically to said axis of stabilization.  For multifocal corrections it is possible to use a third boss, disposed on the vertical axis of the lens.  These stabilizors allow the use of very thin lenses and a perfect centering of the lens, hinder-ing its rotation.

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus is disclosed for drilling a pilot hole and subsequently enlarging the pilot hole in earth formation.          A dual concentric pipe string is used for circulating air downwardly through the outer pipe, through a pilot bit and upwardly through the bore hole outside the pipe string to bail cuttings, during drilling of the pilot hole.  The air pressure expands the cutters of an expansible bit while a limited portion of the air supplied cools the cutters.          After the cutters are fully expanded, additional air is utilized to clean and cool the cutters.  Air is returned through the inner pipe of the dual concentric pipe string.          A venturi device is utilized to induce return flow through the inner pipe during enlargement of the hole to vacuum residue when enlargment is completed.  The dual concentric pipe string is made up of lengths of pipe providing threaded, sealed joints.

Abstract: ABSTRACT OF THE DISCLOSURE Articles which nest, such as baking pans, are assembled into a stack by a two-stage lift mechanism in which the assembly of a second stack is commenced while a previously assembled first stack is being discharged from the stack form-ing apparatus, so that the flow of pans into the apparatus need not be interrupted. Articles such as pans are fed in succession into a stacking station at which the articles are aligned with a vertical path and then dropped.  A first stage lift receives the articles and is lowered one step upon the receipt of each article until the first stage lift is lowered to a transfer station.  At the transfer station, support of the stack of articles is transferred to a second stage lift which is similarly lowered one step upon the addition of each subsequent article to the stack until a preselected number of articles have been accumulated in the stack.  Upon transferring the support of the stack to the second stage lift, the first stage lift is retracted clear of the stack and returned to its upper limit of movement.  When the final article has been stacked on the second stage lift, the first stage lift is re-inserted into the vertical path to receive the next following article to commence assembly of a second stack.  Simultaneously, the second stage lift is lowered to a discharge station where the stack is discharged from the second stage lift which in then elevated back to the transfer station.  The stacker is capable of stacking both bread and bun pans, which are of different height and capable of delivering pans to a discharge conveyor without stacking them.
