Patent CA-2015723-A1 (CA)
IPC: A44B19/60
Filed: 1990-04-30
Abstract: ABSTRACT OF THE DISCLOSURE     A method of applying top end stops on to a slide fastener chain comprises holding a top end stop or stops in between an anvil and a horn, moving the anvil and the horn together into alignment with a path of travel of the fastener chain, threading the fastener chain through the top end stop, clamping and attaching the top end stop by fusion to the fastener chain, and moving the anvil and the horn out of the path of the fastener chain.  This method is reduced to practice by an apparatus which essentially comprises an anvil and a horn which are vertically movable together in one instance toward and away from a horizontal path of the fastener chain and means of moving the anvil independently from and against the horn in another instance to clamp and attach the top end stop to the fastener chain.

Title: Surgical tissue bag and method for percutaneously debulking tissue
Inventor: CLAYMAN RALPH V
IPC: A61B17/00
Filed: 1991-06-18
Abstract: A surgical tissue bag for percutaneously debulking large volumes of tissue contained within the bag. The tissue bag comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag material is foldable and flexible for insertion through an access sheath into the surgical site and for forming a gas-tight seal when extended through the access sheath or puncture site. A drawstring is attached to the open end of the bag to close the bag when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin. After the closed open end of the bag is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continually fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag is completely removed from the surgical site area.

IPC: F02M35/12
Filed: 1991-10-17
Abstract: A motor vehicle intake silencer having a variable length resonance chamber, said length being rapidly changeable in response to engine speed by varying the effective length of said resonance chamber. The present invention for reducing noise comprises a signal processing part, a signal comparing part and a valve driving part. In the signal processing part, a RPM sensor modulates a waveform obtained by detecting the revolution number of the engine and a F/V converter changes it thereafter emitting a signal to the signal comparing part. In the signal comparing part, a plurality of comparators emit the opened and closed signal to a valve driver by comparing a output signal emitted from the signal processing part with a basic signal. In the valve driving part, when the corresponding valve driver turns on or off by virtue of the signal emitted from the corresponding comparator, a corresponding actuator opens or closes the corresponding valve dividing the inside of the side branch. Thus, it can rapidly change its capacity according to the change of the revolution number of the engine and also has the simple structure and the small size.

A detector (14) is provided for generating a signal representative of the magnitude of the output of the subtractor (11). A calculation circuit (17) is coupled to the detector for generating a signal that is inversely variable as a function of the output of the detector. A multiplier (18, 20) scales a stepsize with the inversely variable signal and multiplies the output of the subtractor with the scaled stepsize. The tap-weights of the adaptive filter (13) are controlled according to the multiplied signal.
