Title: Sawing chain for chain saws
Inventor: ROSSMANN CHRISTOPH
IPC: B27B33/14
Filed: 1993-11-09
Abstract: ABSTRACT [(truncated, as published)]    The subject of the invention is a saving chain for chain saws, having a plurality of chain links which are linked together so as to be mutually pivotable in a common plane of extent and advance (which plane is the operating plane of the chain) and which links bear cutting elements.      According to the invention, to facilitate replacement of damaged individual links, and to simplify the driving and guiding of the chain, the chain links are linked together in succession in a direct intermeshing fashion [i.e. not relying on fasteners to mediate the said linkage] of the successive chain links, along edge surfaces which extend transversely to the common plane of extent and advance (which plane is the operating plane of the chain), resulting in a chain structure which is resistant to flexure in the direction perpendicular to the said plane. In a preferred embodiment, each chain link (A, B) has a structure comprising at least three layers, with an inner core piece (K) and two side pieces (S, S') wherewith each core piece (K) has an outwardly and eventually downwardly directed curved-beak-like projection (1) at its "forward" edge (edge in the direction of forward [sic] movement of the chain), and has a hook-like projection (2) at its corresponding "rearward" edge which latter projection is outwardly and eventually downwardly directed and which [eventually (along its extent)] bends back in the "forward" direction; and further each core piece has an upper "rear"     recess (3) shaped complementarily to the said beak-like projection (1), to accommodate the beak-like projection (1) of the next "following" core piece (K) in the direction of the chain path, and a lower "forward" recess (4) which terminates in an articulation shaft (5) for pivotably engaging the hook-like projection (2) of the next "leading" core piece (K) in the direction of the chain path.      In addition, at least two types of teeth may be provided on the chain links (A, B), as cutting elements. [Translator's note: Abstract truncated here.]

Title: Heat set neck finish with segmented threads
Inventor: LABOMBARBE CHRISTOPHER C JR
IPC: B65D1/02
Filed: 1995-01-23
Abstract: A blow molded, PET container having a unitarily formed body defining a hollow cavity for receiving a product. The body includes a base, a side wall, a neck finish and a mouth. The neck finish, located at the upper end of the container, is formed from substantially amorphous PET that has been thermally stabilized by a heat treating process. A thread is formed on the neck finish to receive a closure cap. The thread is generally in the form of a raised ridge that spirals at least partially around the neck finish. Spaced interruptions divide the thread into thread segments which reduce the PET needed to form the neck finish. The interruptions reduce the residual stresses in the neck finish and thereby reduce the distortion which occurs in the neck finish during hot filling or hot washing of the container.

The telephone communication system characterized by at least one telephone line adapted for carrying incoming telephone calls, and a plurality of station sets including an attendant station set for forwarding incoming telephone calls and a plurality of adjunct station sets eachadapted for receiving incoming telephone calls. The attendant station set is coupled to the plurality of adjunct station sets. The information processing system includes a caller identification signal receiver, a timed switching device, and a call forwarding device. The timed switching device is coupled between the incoming telephone line and the call forwarding device. The call forwarding device is coupled between the timed switching device and the plurality of station sets. The caller identification signal receiver is coupled to the incoming telephone line and the call forwarding device. When no incoming call is being received, the timed switching device is in a first, open state, such that a circuit between the telephone line and the call forwarding device is interrupted. Upon receipt of an incoming call on the telephone line, the timed switching device and the caller identification signal receiver are activated. The timed switching device enters a second, closed state after a finite amount of time has elapsed such as, for example, several seconds, thereby allowing sufficient time for the caller identification signal to arrive on the incoming telephone line. The caller identification signal receiverresponds to the receipt of incoming caller identification information by immediately activating the timed switching device, placing the timed switching device into the second state. The call forwarding device, responsive to the caller identification signal receiver, connects the incoming telephone call to a selected one of the plurality of said station sets.
