Patent CA-2205933-C (CA)
Inventor: HALDIMANN HANS-RUDOLF
IPC: B65G1/06
Filed: 1996-10-07
Granted: 2002-01-01
Abstract: In a push back storage assembly, each shelf channel is pro- vided with a conveyor that comprises a continuous moving conveying member. The goods to be stored are non-positively received on the top of the conveying member. In the region of the unloading end of the shelf channel, a stationary slide member is provided, whose active length corresponds to 0.8- to 1.2-times of the mean brake- less running-out distance of the conveying member set in motion by the removal of goods. The frictional contact between conveyor mem- ber and pallet is released in front of the active length of the slide member. Thus, the non-positive connection between conveyor member and pallet is released during unloading of the frontmost pallet before the latter one is completely removed. Thereby, a safe and gentle slowing down of the moving conveyor member is en- sured, without the danger that any goods received in the shelf channel overrun the end thereof.

Abstract: For voice and musical signal, a signal coding system which can obtain good sound quality even at a low bit rate is disclosed.      The signal coding system predicts an input signal in a predicting circuit and performs orthogonal transformation in a first orthogonal transformation circuit of a predicted residual error signal. In a coefficient calculating circuit, a coefficient of a smaller degree is calculated for expressing an envelope of the orthogonal transformation coefficient in the orthogonal transformation circuit. In a quantization circuit, quantization is performed by expressing the orthogonal transformation coefficient with a plurality of pulse trains with determining positions for generating a pulse using the output of the coefficient calculating circuit. The envelope of the orthogonal transformation coefficient is expressed by the coefficient with smaller degree. On the basis of the coefficient, the orthogonal transformation coefficient is expressed by a plurality of pulse trains to perform more efficient coding than that of the prior art.

Abstract: A facemask for a helmet which is of at least two parts and is split in the middle and resiliently mounted on the sides of the helmet. In accordance with the invention, the facemask will tend to open outwardly thereby increasing the likelihood that an opponent's grip on the facemask will be released. The facemask can be releasably mounted on the helmet so that, if the grip is not released, the portion of the facemask being grasped will then "break away" from the helmet. The force required to open up the two-part facemask is less than the force required to cause one or both parts of the facemask to be detached from the helmet. The present invention can be used with helmets for sports such as football, ice hockey, lacrosse, or other contact/collision sports.

Granted: 2002-03-26
Abstract: A refrigerator cabinet has a food storage compartment bounded by front facing vertical and horizontal walls. A pair of French doors are pivotally mounted to the refrigerator cabinet to close the open front of the refrigerator. In the closed position the doors have vertically extending confronting walls which include an intermediate sealing gasket extending along a major vertical portion of the confronting walls which are adapted to sealingly engage against each other to form a vertically extending seal.      Upper and lower corner sealing gasket members are respectively positioned above and below the intermediate sealing gasket members and adjacent a corresponding horizontal wall of the cabinet. Each of the corner sealing gasket members has a first sealing surface adjacent the intermediate sealing gasket member to complete the vertical seal between the confronting walls of the doors when the doors are in a closed position.      The corner sealing gaskets further include a second sealing surface generally orthogonal to the first sealing surface. The second sealing surface in an open position has one vertically extending outwardly protruding ridge contracting the second sealing surface to withdraw the first sealing surface back from its vertical sealing position. The ridge engages one of the horizontal walls as the door closes so as to flatten the second sealing surface into sealing engagement with this horizontal wall and to advance the first sealing surface towards the location of the vertical seal position. Magnetic strips are also located in the corner sealing gasket members to facilitate the sealing of the first sealing surfaces to each other and to the front facing horizontal wall.
