Title: Tool for pulling out the serrated connection plate from the wood and the method of pulling
Inventor: MYKOLAITIS DARIUS
IPC: B25C11/00
Filed: 2018-12-11
Abstract: This description provides a tool for pulling out the serrated connection plate from the wood and the method of pulling using that tool. The tool comprises the following components: a wedge, which is inserted between the wood and the connection plate to lift, to pull out the plate; a support on which the tool leans on during the use, which, together with the wedge, fixes the pulled out plate in the tool, where the wedge and the support are reinforced with each other in a specific, movable between each other manner; a handle, by which the tool is held and operated. During the use, the wedge is placed next to the connection plate for pull-out, the tool is pushed, hit with the handle, in order to intercept the wedge between the plate and the wood, then by lifting the handle the wedge and the support compress the connection plate, thereby entrenching the connection plate in the tool. Continuously lifting the handle, the part of the plate entrenched into the tool is raised upwards by pulling out the entire plate. The present tool allows to pull out the connection plate from the wood quickly, using minimal movements and forces. The plate is folded, deformed just slightly by pulling out, could be reused.

Patent NL-177053-B (NL)
IPC: G04C21/16
Filed: 1977-04-28
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.

Patent PT-88473-B (PT)
Inventor: BAUKLOH ACHIM
IPC: B24C3/32
Filed: 1988-09-09
Abstract: The corrosion damage, particularly that due to local pitting, which occurs on hard-drawn copper tubes used in the sanitary sector is generally caused by carbon-containing films but also by oxide films. A carbon film on the inside of the tube is formed, for example, if the drawing compound added when drawing the tube is subjected to excessive heat. To avoid these damaging films and to improve the pitting resistance of hard tubes made of copper or copper-based alloys, the tubes are first of all degreased. In a further process step, the inner surface of the tubes is then treated with a blasting abrasive in order to establish a minimum roughness. A mean roughness of 0.8 to 1.0  mu m has proven particularly advantageous. The hard-drawn tubes treated by the method according to the invention have none of the films which promote pitting, even after brazing and/or hot bending.
