Title: Hard material collecting system for a meat grinder
Inventor: LESAR NICK J
IPC: B02C18/30
Filed: 1992-02-12
Granted: 1996-07-23
Abstract: An arrangement for discharging hard material from the grinding head (10) of a meat grinder. The hard material is passed through openings (32) formed in the meat grinder orifice plate (18), and collected in a collection cavity (76) defined by a cup member (74). A hard material discharge auger (84) is located within the collection cavity (76), and is rotatable with the feed screw (14) of the grinder. A restricting arrange-ment is provided for building up back pressure within the collection cavity (76), which minimizes   the amount of usable soft material which passes into the collection cavity (76). In one form, the discharge au-ger (84) extends through the collection cavity (76) and into a discharge passage defined by a discharge tube (82).  The auger (84) has an outside diameter only slightly smaller than the diameter of the passage, so that the auger (84) essentially defines a rotating flow path through which the hard material is discharged.

Title: Erasable printing form
Inventor: HIRT ALFRED
IPC: B41C1/10
Filed: 1993-10-20
Granted: 1998-12-08
Abstract: A method for producing an erasable printing form by making the outer layer of the printing form from a material containing strong micro-dipoles, preferably a ferroelectric material, in particular a ferroelectric ceramic. In wet offset printing, the non-printing areas of the printing form are rendered hydrophilic by a hydrophilizing agent and they are maintained during the entire printing process. Plate cleaners can, for example, be used as the hydrophilizing agents. The printing form can be erased by a non-polar solvent and can be reused again by rendering the non-printing areas hydrophilic again.

Abstract: A barcode printer system is shown having a host processing system in communication with a barcode printer. The host processing system converts multi-level user input printer commands into a data stream in the printer control language of the barcode printer for transmission to the printer. The host processing system stores a number of printer command function routines, each of which is associated with a number of multi-level user input printer commands. Each user input printer command includes format and data information in a single command. A low level user input printer command, however, may include only a user readable word and data, the host processing system automatically utilizing stored default values for the format information when converting the command. A higher level user input printer command may include an abbreviation designating the command and values for one or more format variables as well as data. The multi-level user commands are not fixed in length so as to be user friendly for low level users but flexible for higher level users.

Abstract: The plasma gun head for plasma spraying apparatuses essentially comprises a cathode body member, an anode body member and an insulating member inserted there between and electrically insulating these two members from each other. Inserted into the cathode body member is a cathode assembly, and into the anode body member an anode nozzle, both extending transverse to the longitudinal axis of the plasma gun head. The anode body member and the cathode body member both are provided with cooling channel sections which are connected in series as seen in the direction of flow of the cooling medium. The anode nozzle is rigidly integrated into the anode body member; thus, it is not necessary to provide sealing elements in this thermally highly stressed region. The sealing elements required for sealing the cooling channel sections are located remote from the anode nozzle and the cathode assembly, respectively, in a region, which is thermally not stressed.

Abstract: La présente invention a pour objet un procédé d'amplification et de détection de molécules cibles d'acide nucléiqe à simple et à double brin. L'amplification de la molécule cible d'acide nucléique est réalisée à l'aide d'au moins deux sondes d'oligonucléotides modifiées chimiquement par molécule cible d'acide nucléique, pour former un produit oligonucléotidique assemblé. Chaque sonde d'oligonucléotide se compose d'une séquence longue et d'une courte. La séquence longue de chaque sonde s'hybride avec des régions adjacentes de la molécule cible d'acide nucléique. Les séquences courtes de chaque sonde s'hybrident l'une avec l'autre. Les groupes de fonctionnalité chimique liés aux séquences courtes de chaque sonde d'oligonucléotide se combinent de façon covalente en liant les sondes pour former un produit oligonucléotidique assemblé. Le produit oligonucléotidique assemblé est formé sans utiliser d'enzymes. La réactivité des groupes de fonctionnalité chimique de chaque sonde est dépendante de la cible. Ce n'est que lorsque les séquences courtes de sondes adjacentes sont hybridées les unes avec les autres que les groupes de fonctionnalité chimique des sondes sont amenés à proximité suffisamment étroite pour former une liaison covalente et réunir les sondes pour former un produit oligonucléotidique assemblé.

Abstract: In a slider for a slide fastener, front and rear attachment lugs are arranged on the upper surface of an upper wing of a slider body, each having a horizontal insertion hole and an arcuate guide surface contiguous to the insertion hole.  A pull tab retaining bar has a length so as to bridge over the front and rear attachment lugs and has a pair of taper legs one on each end.  For assembly, with a pintle of a pull tab placed between the two attach-ment lugs, the legs are forced into the insertion holes along the guide surfaces as they deform prastically, securing the pull tab retaining bar to the attachment lugs. Accordingly, the pull tab retaining bar can be attached to the slider body simply by pressing from the upper side, thus facilitating automatic assembling.
