Patent CA-2201997-A1 (CA)
Inventor: UREN ALBERT
IPC: B23P19/06
Filed: 1997-04-07
Abstract: A nut frozen to a rotatable threaded shaft can be unloosened from the shaft by inserting a split haft-clamping member onto the shaft, and maintaining a squeezing force on the clamping member while a wrench is applied to the nut. The clamping member holds the threaded shaft in a fixed, non-rotary, condition, thereby preventing the shaft from turning with the nut.

Title: Coolant compositions
Inventor: PONGE JEAN-LOUIS
IPC: A23L27/00
Filed: 1996-08-29
Abstract: The invention relates to refreshing compositions, flavouring compositions and ingestible and topical compositions containing at least a refreshing compound selected amongst monomenthyl succinate, alcaline metal salts of monomenthyl succinate, alcaline-earth metal salts of monomenthyl succinate and mixtures thereof. Said compositions provide a durable, bitterness-free, pleasant and refreshing effect, and said refreshing feel is different from that of other known refreshing agents. Consequently, a complementary or synergic effect can be obtained by combination with other refreshing agents. Furthermore, the succinate-based refreshing compounds according to the invention provide for an increase of alcohol feel in alcoholic drinks. Finally, the succinate-based refreshing compounds provide a refreshing taste when they are applied to filters, combustible papers and sheets for wrapping tobacco products for smoking and when they are incorporated into tobacco products for chewing or snuffing.

Title: Method and device with active oscillation damping for winding a web of paper into a roll
Inventor: MADRZAK ZYGMUNT
IPC: F16F9/06
Filed: 1997-07-18
Abstract: An oscillation suppression resonator suppresses oscillations of a large oscillating mass in paper machine winding devices.  A support device is connected with the large oscillating mass and a predetermined oscillation suppression means is movably arranged as the support device.  Cylinders, which can be filled with gas or fluid, are firmly attached to the support device.  The pistons of the cylinders are connected via piston rods with the mass movable on the support device.  In this manner, upon deflection of the mass from an equilibrium position, a substantially harmonic oscillation takes place with a frequency which is determined by the pressure prevailing on the cylinder. The oscillation suppression resonator is employed particularly in a device for winding traveling webs of material, particularly paper webs, so as to form a roll.

Abstract: This invention relates to a motorized washing machine that will quickly clean a person's hands. It is used by switching it on and inserting both hands into the porthole openings. The rapidly moving brushes will quickly scrub the person's hands clean. In drawings that illustrate embodiment of the invention, Figure 1 shows the machine from the front and Figure 2 shows the machine from a side view. The machine consists of a motor (1) which turns a crank assembly (2) which reciprocates the cleaning brushes (3).  A submerged pump motor (4) sprays heated wash water from the spray nozzle (5) onto both hands and the brush area. The wash water is continually recycled until it is too dirty for reuse and is flushed into the sewer by opening the flapper valve (6). When the wash water has been dumped out the float valve (7) opens and sprays clean water into the machine interior and shuts off after the machine has refilled. An electric heater (8) will heat the wash water to increase the cleaning action of the machine. The short bristle brush (9) is designed to clean under the fingernails.

Patent CA-2231239-A1 (CA)
Title: Method and apparatus for transporting auxiliary data in audio signals
Inventor: LEE CHONG U
IPC: H04J13/00
Filed: 1996-08-20
Abstract: Auxiliary data (x(m)) is transported in a conventional audio signal (s(t)) by hiding the data in the form of colored noise (y(t)). The colored noise has a spread spectrum that simulates the spectrum of the primary audio signal. The data to be transported is first converted to a spread spectrum signal (p(n)).  The primary audio signal is analyzed to determine its spectral shape (88). The same spectral shape is imparted to the spread spectrum signal (94), which is then combined with the primary audio signal for transmission (100). The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding (88) or by using subband coding techniques such as fast Fourier transforms. A plurality of different auxiliary information streams can be transported on the audio signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise (98), the auxiliary information stream(s) can be rendered inaudible in the primary audio signal, or at any desired level below or above an audible threshold.
