Title: Apparatus for hard facing saw blade teeth
IPC: B22D19/06
Filed: 1974-04-25
Abstract: Saw blades such as endless band saws have the cutting tips of the saw teeth faced with a hard alloy such as Stellite and shaped by half molds straddling the sides of the saw and an end stop member successively aligning the saw teeth with the molds and then also shaping the end face of the tip. The mold sections cooperate to form an open front and open top mold cavity around the tip end of the saw tooth. Molten alloy from a rod is projected into this cavity by a torch flame to form a bead on the saw tooth tip and the stop member then descends to close the front of the mold cavity and cooperate therewith to shape the alloy around the tip in welded relation therewith. Alternately, the alloy can be deposited in the mold cavity in powder form and melted by the torch to be welded and shaped on the saw tooth. The mold components are swingable between open and closed positions and the stop component is raised and lowered from the space between the teeth permitting the saw blade to be advanced after each molding step and serving as an indexing means to stop the advancing saw blade at the next tooth to be tipped. The side mold members can be in the form of blocks with the mold defining cavities in their corners and arranged to be shifted to present fresh mold cavity defining walls to the saw blade in the event of wear or damage of the previously used cavity walls and the stop face of the stop member can be a multi-face block that is rotated to present fresh shaping surfaces.

Patent ES-8102687-A1 (ES)
Title: Autoreverse Tape Cassette Deck
IPC: G11B15/44
Filed: 1980-03-20
Abstract: The deck includes an arrangement for playing the preferential track when a cassette is inserted. In normal operation, a motion detector 5,1 switches to a high output when the take-up spool 5 stops and multivibrator 2 then produces an output to actuate relay R via transistor 6 and cause the tape to reverse. Switches S2 and S3 are controlled by a bistable member such that S2 is closed and S3 open when the tape is moving in the preferential direction and S3 is closed and S2 open in the other direction. When start switch S1 is closed the output of bistable 3 is reset to 0 via capacitor C. If S3 is then closed (non-preferential direction), OR gate 4 gives a 0 output to reverse the tape. S2 then closes to set bistable 3 and hold the OR gate output high. Thereafter capacitor 8 charges and bistable 3 cannot be reset until the cassette is ejected.
