Title: Process and device for injection moulding plastic pots
Inventor: DOEBLER WALTER
IPC: B29C45/14
Filed: 1992-03-18
Abstract: A process and device for injection moulding plastic pots (5) are disclosed. An envelope foil (18) in the form of a label is integrated into the pots by the in-mould labelling process. According to the process disclosed, a male (1) and a female mould (2) are moved coaxially into which molten plastic is injected through an aperture in the mould. During the opening and closing movement of the mould, a suction holding pin (3) can be moved in a position coaxial with the male (1) and female mould (2), whereafter the entire mould (2) is divided into a base section (9) retaining its momentary position and a movable section (22) which is pushed on a partial region of the suction holding pin (3) to take the envelope foil (18) and held there by suction via a suction slot (20) and then moved back to the base section (9) and reunited with it to form the entire mould (2). The suction holding pin (3) is then pivoted out of the intermediate space again by moving the female (2) and male mould (1) together and the suction slot (20) is closed by pressure between the female (2) and male mould (1). The advantage of the invention lies in the simplification of the injection moulding device while at the same time simplifying the cycle of movements in the injection moulding process.

Patent CA-2127035-A1 (CA)
Title: Process for separating fibres from composite materials
Inventor: SIMS BRYAN
IPC: B29B17/02
Filed: 1994-06-29
Abstract: Abstract A resin reinforced fibre product such as glass fibre impregnated with a thermosetting resin is treated to recover fibre by initially shredding the waste, pulverizing the shredded waste and sieving the pulverized waste to separate the free fibres.  The remaining waste is milled to produce a fine powder suitable as a filler. The pulverizing is completed without classification and a portion of the pulverized product above a nominal cut size recampaigned.  Free fibres are separated by an airlift during the sieving process.  Further separation of shorter fibres is obtained from the throughs by processing by a sifter to separate dust and subsequent screening at a larger mesh size to separate particulate material.
Patent CA-2129161-A1 (CA)
Inventor: OZAWA KAZUNORI
IPC: G10L19/08
Filed: 1994-07-29
Abstract: In a code excited speech encoder, an input speech signal is segmented into speech samples at first intervals and a spectral parameter is derived from the speech samples that occur at second intervals longer than the first intervals, the spectral parameter representing the characteristic spectral feature. Each speech sample is weighted with the spectral parameter for producing weighted speech samples. The pitch period of the speech signal is determined from the weighted speech samples. A predetermined number of excitation code vectors having smaller amounts of distortion are selected from excitation codebooks as candidate code vectors. The candidate vectors are comb-filtered with a delay time set equal to the pitch period. One of the filtered code vectors having a minimum distortion is selected. The selected filtered code vector is calculated for minimum distortion and, in response thereto, a gain code vector is selected from a gain codebook. Index signals representing the spectral parameter, the pitch period, the selected excitation and gain code vectors are multiplexed for transmission or storage.

Title: Intermediate frequency combiner for radio communications system
Inventor: GARNER CHARLES L
IPC: H04B7/08
Filed: 1994-08-02
Abstract: ABSTRACT   A signal combiner for use in a space diversity radio receiving system, that accepts two signals which have been received at physically diverse locations and which have been converted from radio frequency to intermediate frequency. Each signal is checked for signal strength and for amplitude versus frequency dispersion, and is run through a separate amplitude slope equalizer which removes amplitude slope. Each signal is then run through a separate squelch circuit which either attenuates the signal, or passes it on undiminished. The squelch circuits are controlled by control circuit which selectively activates one or neither of the squelch circuits based on the difference in signal strength between the two received signals and the signal dispersion of each of the signals. The outputs of the squelching circuits are then combined to create a composite signal which is comprised of one or both of the equalized signals.

Filed: 1995-02-22
Abstract: A seal construction is provided for sealing a rotating pump shaft against passage of a fluid along its central axis.  The seal construction includes front and rear sealing flanges mounted coaxially to and rotatable with the pump shaft.  Stationary engaging members are provided adjacent the rear surface of the front sealing flange and the front surface of the rear sealing flange for sealing engagement therewith.  Diaphragms are provided across fluid passageways associated with each engaging member thereby allowing the pressure of fluids adjacent each engaging member to dictate the force to be placed by the diaphragm on the sealing engagement between the corresponding engaging member and surface of the associated sealing flange.  A temperature stabilized chamber is provided adjacent each sealing flange including means for recirculating and cooling fluid disposed therein so as to maintain the fluid between adjacent engaging members at a substantially constant temperature thereby maintaining a flatness of the sealing engagement between the sealing flange surfaces and the engaging members.  The recirculating/cooling system includes a plurality of vanes mounted on and integrally formed with the sealing flange, the vanes causing the fluid within the chambers to flow circumferentially around the pump shaft and exit the chamber by way of an exit orifice, then reenter the chamber through an entry orifice with the fluid being cooled at a location in the circulation line remote from the chamber disposed between adjacent engaging members.

Abstract: Procédé d'amplification d'une séquence d'acide nucléique cible consistant essentiellement à obtenir un polynucléotide tel que VII comprenant la séquence à amplifier et comprenant en outre la séquence d'un promoteur d'ARN polymérase, et à mettre en contact ce polynucléotide, en présence d'un système ayant une activité d'ARN polymérase, une activité d'ADN polymérase ARN-dépendante et une activité d'ADN polymérase ADN-dépendante, et ayant une capacité de déplacement de brins, avec un ensemble d'amorces comprenant une amorce telle que A capable de s'hybrider avec un segment complémentaire d'une partie de la séquence à amplifier, A comprenant en amont une séquence de promoteur d'ARN polymérase puis une séquence arbitraire, une amorce telle que D contenant ladite séquence de promoteur d'ARN polymérase, et une amorce telle que C comprenant ladite séquence arbitraire. Le produit d'élongation de D est déplacé par le produit d'élongation de C, et on obtient donc le produit d'élongation de D sous forme de monobrin VIII. L'hybridation de A sur VIII, suivie d'élongation, conduit au produit double brin X dont la transcription conduit, avec amplification, notamment à l'ARN simple brin VII bis. Un système analogue de 3 amorces B, E et F conduit de façon similaire, à partir de VII bis, à l'ARN simple brin VII, d'où le caractère cyclique de ce procédé d'amplification capable de fonctionner de façon isotherme.
