Patent CA-2156639-A1 (CA)
Inventor: KOTZIN MICHAEL DALE
IPC: H03M7/30
Filed: 1994-12-22
Abstract: Audio degradation is minimized in scenarios where tandem coding occurs. One such scenario is in the environment of voice mail service. Characteristics of an audio information signal are determined, and the signal is classified (303) as to whether further coding (306) should be performed and, if so, which rate/type of coding should be performed. Characteristics of the audio signal which are determined are, inter alia, quality characteristics, rate of previous coding, type of previous coding and the source of previous coding of the audio information signal. The source of previous coding determined may further include, inter alia, an analog network, a digital network, a PSTN or a wireless communication system. Based on this information, the voice mail service will either choose not to further code the audio information signal or code the audio information signal with the best coding algorithm available.

Title: Method and apparatus for recovering refrigerant
Inventor: HANNA WILLIAM T
IPC: F25B45/00
Filed: 1995-11-27
Abstract: Apparatus for recovering refrigerant from a refrigeration system having a high pressure liquid side and a low pressure vapor side comprises a storage receptacle for receiving recovered refrigerant, a liquid flow circuit for recovering liquid from the high pressure side of the system, a vapor flow circuit for recovering vapor from the low pressure side of the system, and a vapor feedback flow circuit from the receptacle to the inlet side of a vapor reducing section of the vapor flow circuit. The apparatus is operable in a liquid recovery mode and in a vapor recovery mode, and an arrangement for automatically purging non-compressible gases from liquid refrigerant is provided in the vapor flow circuit on the downstream side of the vapor reducing section thereof. During a liquid recovery operation, vapor is fed back from the storage receptacle to the inlet side of the vapor reducing section and non-condensable gas in the liquid refrigerant flowing therefrom is separated from the liquid prior to return of the liquid refrigerant to the storage receptacle. During a vapor recovery operation, the apparatus is operable to shift back to the liquid recovery mode in response to a high pressure in the storage receptacle, whereby vapor in the receptacle is fed back and reduced to a liquid from which non-condensable gas is removed prior to return of the liquid to the receptacle. Gas removed from the liquid refrigerant is accumulated and periodically exhausted to atmosphere.

Patent CA-2166347-A1 (CA)
Title: Anti-barking and anti-biting muzzle for dogs
Inventor: PAGLERICCIO FERNANDO PAULO
IPC: A01K25/00
Filed: 1995-12-29
Abstract: An anti-barking and anti-biting muzzle for dogs includes a muzzle portion formed from a pair of generally trapezoidal flaps of elastic material sewn together along the converging edges thereof, with the flaps being further divided by a seam along the longitudinal centerline thereof  to create  four panel members  of  the elastic material.   An elongated strap is connected at its ends to opposed seams of the muzzle portion.  The muzzle can be slid onto the snout of a dog and the strap fitted over the dog's head behind its ears.  The muzzle portion has a snug fit on the snout but the elasticity of the material allows the dog to open its jaws slightly for panting.  If the dog tries to open its jaws wider to bark or bite the four elastic panel members apply a force to the jaws to prevent them from opening wide.  The muzzle is not uncomfortable and it acts as a training aid since the animal associates the wearing of the muzzle as a form of punishment for barking or biting.  It soon learns to stop barking or biting when it event sees the muzzle.   The muzzle can be quickly removed by applying an upward or lifting force on the strap behind the ears, important if the dog is relied upon to provide security for a human attendant.

Abstract: Dans un système d'adressage à trois fentes pour un modulateur optique à cristaux liquides dans lequel les formes d'ondes (1, 2) de données comprennent une section de données (34), une section d'équilibrage de charge (36) ainsi que'une troisième section (38), la forme de cette dernière dépend de la séquence de formes d'ondes de données. La troisième section, ou la paire de sections supplémentaires adjacentes comprend une paire d'impulsions de polarités opposées qui s'équilibrent réciproquement en charge. L'ordre selon lequel ces impulsions apparaissent dans la paire renforce l'effet de la section de données adjacente afin de faciliter ou d'inhiber la commutation comme il convient. Ceci permet d'obtenir un intervalle d'adressage de ligne plus court.

IPC: H05B41/295
Filed: 1996-03-15
Abstract: To largely, or entirely inhibit glow discharges during the start-up or run-on phase (Ta) of a high-pressure discharge lamp, the lamp is operated in a second time period (T2) immediately after ignition (T1) with continuous direct current during which the electrode of the lamp which then functions as an anode has reached emission temperature; in a third time period (T3), the polarity of the direct current is reversed and the other electrode, which now will function as an anode, is heated to emission temperature; thereafter, alternating current energy is supplied to both electrodes, typically in frequencies between 90 and 150 Hz. A suitable second time period (T2) can be about 2 to 2-1/2 second, the third time period (T3) being shorter. The total warm-up time may extend to a minute or more; current being supplied during the second, third and subsequent periods is usually higher, for example by a factor of 1.5 of the normal or rated operating current.

Title: Method and apparatus for an anticipatory thickness control in foil rolling
Inventor: HARTUNG HANS-GEORG
IPC: B21B37/16
Filed: 1996-03-29
Abstract: A method arid an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer, Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap. For example, the tensioning unit elongates the travel path.

Abstract: A method and apparatus for indexing data entry records groups in a plurality of raw data entry records, each data entry records group having at least one of the data entry records with at least one key field containing an item, includes a master list of items in the raw data to be indexed.  A data entry records group is read and a tally of a key number representing a total number of the key fields in the data entry records group is generated. In some cases, the key fields are sorted in a predetermined sequence, duplicate key fields are removed and the key number is adjusted for the key fields removed. An index record having a predetermined number of key fields equal to the key number and a first pointer related to instructions for processing any other data entry records group having the same combination of key fields is generated. Each item in the key fields of the data entry records group is mapped to generate a corresponding item indicator in the key fields of the index record. If the index record matches an existing index record, the instructions related to the first pointer are executed. If the index record is new, a second pointer is added related to a location of the data entry records group in the plurality of data entry records.
