  • Publication number: 20230333005
    Abstract: Methods, apparatuses, and systems for providing a sealed glass enclosure for a gas detecting apparatus are provided. An example method may include: preparing a controller component that is operatively coupled to a sensing element, wherein the controller component comprises at least one electrical connector; joining a first glass component and a second glass component to form a unitary body such that the at least one electrical connector is disposed therebetween; preparing a glass tube comprising an open surface; disposing the controller component and sensing element within the glass tube; positioning the unitary body comprising the first glass component and the second glass component adjacent the open surface of the glass tube; and encapsulating the unitary body to the glass tube to form the sealed glass enclosure.

  • Patent number: 11597270
    Abstract: An actuating apparatus for opening and closing a cover in or on a vehicle has a blocking device for blocking the cover in a locked position. The blocking device has a transmission mechanism with a rotation part (64.1; 50) mounted rotatably and driveable by an actuator (34), and a blocking bar (62) which is operatively connected to the rotation part. The transmission mechanism converts a rotation movement of the rotation part into an axial movement of the blocking bar. The blocking bar is transferable with the aid of the rotation part from a release position into a blocking position. The transmission mechanism is self-locking so that, at least whenever the blocking bar is in the blocking position, the rotation part is not driveable via an axial movement of the blocking bar, and the rotation part prevents an axial movement of the blocking bar out of the blocking position.

  • Patent number: 11235659
    Abstract: An actuating device for opening and closing a cover in or on a vehicle includes a housing, a rotatable plunger, a spring that preloads the plunger into a discharge position, and an actuating sleeve into which the plunger can be introduced. At least one actuating groove extends helically around the longitudinal axis of the actuating sleeve and is formed on the inside of the sleeve. At least one actuating projection of the plunger engages into the actuating groove when the plunger is introduced into the actuating sleeve causing the plunger to rotate about its longitudinal axis during an axial relative movement between the actuating sleeve and the plunger. A blocking device blocks plunger movement into the discharge position to hold the plunger in a locked position. A spring element preloads the blocking device into a blocking position, and an actuator disengages the blocking device from the blocking position.

  • Patent number: 9561888
    Abstract: A beverage can end for seaming onto a can body may include a peripheral wall, a center panel, a tab attached to the center panel by a rivet (56), a tear panel (41b), a main reference line (RM), a transverse reference line (RT), and a score (31b). The score may include arcuate main score (31b) that defines a main portion of the tear panel (41b) and a score extension (32b) that defines a vent portion. The score may be configured such that actuation of the tab from its horizontal rest position to an intermediate position ruptures the main score portion (31b) to pivot the tear panel main portion (40b) about the hinge and further actuation of the tab by twisting from the intermediate position ruptures the score extension (32b).

  • Publication number: 20030177803
    Abstract: A method and apparatus for reforming the base profile of a can by using the difference in rotational speed of concentric shafts (A, B) to move a roller (5) radially into contact with the can base. A cam (10) is fixed to one (B) of the shafts and a pair of cam followers (12, 14) is mounted on a support block (6) which is connected to the other shaft (A) via linear bearings (7, 8). The support block also carries the reform roller and causes it to rotate around the can base.

  • Patent number: 5874217
    Abstract: Methods of genotyping canines by analysis of polymorphisms in the number of microsatellite DNA repeats are provided. The internal repeat sequence is amplified by the use of specific primers. The number of repeats, and therefore the distance between the primers, is highly variable in a population, thereby providing an allelic marker for the locus. The combined information from multiple loci provides a means of distinguishing individuals, even among inbred dog breeds, for parentage testing, forensic testing and analysis of individuals relatedness.

  • Patent number: 5707809
    Abstract: Avian nucleotide sequences for use as sex specific markers are provided. Probes or primers derived from the sequences find use in defining the sex of a bird, by producing hybridization patterns or amplification products that are sex-specific. For a given avian species the probes may hybridize to both Z and W chromosomes so as to differentiate between the two chromosomes on the basis of restriction fragment length polymorphisms. Alternatively, the probes may hybridize exclusively to one of the two sex chromosomes in some species. The sequences taught are also useful for the isolation of other nucleotide sequences that are sex specific markers.
