Title: Method of Operating an Injection-Molding Machine with Mold-Protecting Device
Inventor: HERBST RICHARD
IPC: B29C45/84
Filed: 1993-06-11
Abstract: In an injection-moulding machine with mould protection, a predetermined number N of injection-moulding cycles is carried out with a greatly reduced machine rate on each startup so as to operate the mould protection with increased sensitivity during these cycles. If the N cycles remain free of malfunctions, the machine-rate is increased stepwise or continuously to the operating rate, it being possible either to switch off the mould protection or to continue to operate it with an adapted sensitivity. <IMAGE>

Title: High-definition video encoding system having color-sensitive quantization
Inventor: NAIMPALLY SAIPRASAD V
IPC: G06T9/00
Filed: 1993-07-12
Abstract: ABSTRACT           A video signal encoder uses an encoding system such as that developed by the Moving Picture Experts Group (MPEG).  A key component of this encoding system increases the quantization step size of image data, thus decreasing its quantization resolution, to reduce the number of bite used to encode the data.  Apparatus according to the present invention, monitors the color information being encoded and inhibits or reduces any increase in quantization step size for the luminance component and the color component of the image when signals representing saturated or nearly saturated red image components are being encoded.

Abstract: A telescoping antenna device of the type having a tubular pole for receiving therein a telescoping antenna rod, a spacer ring received in a lower portion of said pole and disposed concentrically between said antenna rod and said pole, and a molded component constituting a feeder unit and disposed above said spacer ring, wherein said spacer ring and said molded component are assembled together, with an upper end surface of said spacer ring confronted with a lower end surface of said molded component, at least said upper end surface of said spacer ring having a portion extending upwardly from an antenna rod side toward an pole side of said spacer ring.  By virtue of formation of the upwardly extending upper end surface portion, water penetrating from the antenna rod is prevented from flowing from the antenna rod side into the pole side through the interface between the spacer ring and the molded component.          Thus, the pole is protected against corrosion with penetrating water.                  :

Patent CA-2112400-A1 (CA)
Inventor: GRUENBACHER DANA P
IPC: B65D81/00
Filed: 1992-07-02
Abstract: A conformable, self-aligning, high extraction efficiency coffee filter pack (1) capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk coffee and a paper filter under identical brewing conditions, but which exhibits substantially consistent pot-to-pot brew strength for any given automatic drip coffee maker. The preferred filter pack (1) is formed from two layers of flexible material (10, 20) which are secured to one another about their outermost periphery with a predetermined quantity of roast and ground coffee (50) housed within a brew chamber (40) formed between the two layers (10, 20). The brew chamber (40) exhibits a maximum volume between about 25 percent and about 300 percent greater than the volume of the dry roast and ground coffee (50) contained therein. The discharge flow rate from the brew chamber (40) is slower than the inlet flow rate into the brew chamber (40) to permit a buildup of water and flooding of the brew chamber (40). The flexible conformable sidewall (25) surrounding the brew chamber (40) extends upwardly a vertical distance which is at least sufficient to capture enough hot water to totally immerse the brew chamber (40) when the brew chamber (40) is in its fully expanded condition. This causes the roast and ground coffee (50) within the chamber to expand and float throughout the remaining portions of the brew cycle, thereby establishing a steady state brewing condition which is highly effective in maximizing coffee/water contact as the hot water passes through the brew chamber (40) on its way to the pot.

Title: Method and apparatus for radar measurement of ball in play
Inventor: NUTTALL JERRY A
IPC: A63B71/06
Filed: 1992-08-19
Abstract: A system for continuously and precisely measuring the positions of a generally symmetrical object, e.g., a tennis ball, in motion in a predefined three-dimensional region, e.g., a tennis court (300), which transmits multiple radar signals from first, second, and third, spaced antenna devices (200, 202, 204 etc.), respectively, into the three-dimensional region. Multiple return signals are sensed and are compared with the transmitted signals to determine the phases of the return signals, to thereby obtain ambiguous ranges of the object. Ambiguities are removed by using the Chinese Remainder Theorem to obtain less-ambiguous ranges. A  mathematical model defining boundaries of the three-dimensional region is completed by placing signal reflector devices (320-325) on various boundary points of the three-dimensional region, and transmitting the radar signals when the object is not in the three-dimensional region. Further, the return signals are processed to obtain an initial survey of the region and then to periodically resurvey the region, for calibration of the system.
