Patent CA-2074691-A1 (CA)
Inventor: FUJI HIROSHI
IPC: G11B20/10
Filed: 1992-07-27
Abstract: An information reproducing circuit has a generating means, having virtually the same frequency transfer characteristic as a recording means. The generating means generates a slice signal having a level larger than the negative peak and smaller than the positive peak of a signal read out from a recording medium. A comparator compares the level of the readout signal with the slice signal and converts the readout signal into a binary signal. The information reproducing circuit is designed to minimize jitter contained in the readout signal, which appears due to the frequency transfer characteristic of the recording means. This is achieved by using the level variation of the slice signal, due to the selected frequency transfer characteristic of the generating means. Therefore, the signal read out from the recording medium can be accurately converted into a binary signal even if it contains jitter. Thus, the reliability of the reproduced data can be enhanced.

Title: Snowmaking gun
Inventor: HANDFIELD LOUIS
IPC: B05B7/06
Filed: 1992-11-04
Abstract: ABSTRACT OF THE DISCLOSURE An air/water snowmaking gun includes a pair of concentric shells defining an annular compressed air chamber and an annular discharge slot, and a central water nozzle for spraying an annular stream of water droplets into the center of the stream of air for mixing therewith downstream of the gun.  The water nozzle is controlled by a valve which effects volume control, and a turbine is used to effect self-atomizing of the water into droplets.  The pattern of the water, i.e. cylindrical or flaring is controlled at the discharge end of the nozzle by a pattern control sleeve. The water and air are discharged separately from the gun with their own momentum energy, and only after leaving the gun is there a gradual combination of the two in the plume and entrained ambient air, whereby, temperature permitting, sufficient heat is removed to form snow.

Title: Slide-resistant container
Inventor: HAWKES SPENCER J
IPC: B65D25/20
Filed: 1993-03-10
Abstract: ABSTRACT OF THE DISCLOSURE     A container such as a trunk organizer for a plurality of articles.  The container has a floor and an inner wall which extends upwardly to an upper edge.  An outer flexible wall extends downwardly from the upper edge and below the lowermost undersurface of the floor to support the container, providing slide resistance.  The distance which the outer wall extends below the lowermost floor undersurface is between about 3/16 and 3/8 inch to allow flexing of the outer wall so that the floor contacts a surface on which the container rests to aid in supporting heavier loads whereby the outer wall thickness may be reduced for cost savings as well as to provide the required flexibility.  The container may be "clicked" onto a mat having bosses uniformly spaced and sized, with the bosses engaging the inner surface of the lower outer wall portion, the mat having a slide-resistant lower surface.

IPC: G05D9/12
Filed: 1993-03-11
Abstract: A control system for synchronous condensing operation of a hydro-electric turbine-generator wherein the draft tube water level for the turbine is controlled through the use of that generator's power or current consumption. Either parameter may be used in the process. Water impacting the turbine will increase both of these parameters above an optimum minimum value. Either a generator power or current device provides a signal to a control circuit. When the signal from either device exceeds a preset value, the control circuit injects compressed air into the turbine cavity until the signal returns to its optimum value.
