摘要:
In the processing of a biological reaction system, there is a need for consistently placing an amount of fluid on a slide. In order to accomplish this, the dispense chamber (412) is substantially in line with the reservoir chamber (408), the reservoir chamber piston is removed, and the flow of fluid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices. Also, to reliably catalog data which is used by the automated biological reaction system, data is loaded to a memory device, which in turn is used by the operator to update the operator's databases. The generation of the sequence of steps for the automated biological reaction device based on data loaded by the operator, including checks to determine the ability to complete the run, is provided.
摘要:
A suspended concrete bucket for dispensing concrete in building sites. A shutter is disposed at the at the cement releasing aperture of the bucket. The shutter is horizontally slidable, controlled by a handle. Opening of the aperture is controlled by an operator sliding the shutter on wheels. The released cement flows through the opened aperture into a hose, for pouring into forms.

The invention relates to a sealing and safety device which is made from a flexible elastomer material and which is used for filling a hollow body with a liquid by means of a gun dispenser. The inventive device comprises (i) a ring seal (13) which is intended to surround the dispensing gun and to obstruct the release of gases from the hollow body and (ii) a valve (15) which, in the event of excessive overpressure in the hollow body, can only open towards the outer atmosphere, such as to create a passage for the release of the liquid and/or gas.
摘要:
A beverage dispenser (20) with a faucet assembly (42) manually removably attached to an integral, stainless steel, U-shaped outlet pipe (52) having a generally horizontal section (74) that extends outwardly from the enveloping side (76) has a faucet with a faucet shank ( 48) for mating overlapping connection with the horizontal section (74) and a faucet latch member (78) carried by the faucet shank (48) and a mating outlet pipe latch assembly (90,92) for releasable latching engagement with the faucet latch member (78) to releaseably lock the faucet shank ( 48) to the outlet pipe (52). A faucet guard assembly (60,60') with a generally horizontal section (144) secured to the bottom (26) of the dispenser (20) has a lowermost guard surface (142) located at or beneath a lowermost portion of the faucet nozzle (50) to prevent snagging of the faucet nozzle (50) with the inside of a cup held up to the nozzle for receipt of beverage from beneath the nozzle, and an upturned section (124) in front of the faucet (46) that is at least partly transparent to enable viewing of the nozzle from in front of the guard and may carry a removable U-shaped beverage name or product label (130).
摘要:
Eine Spritzpistole (1), welche insbesondere für das Verspritzen abrasiver Medien geeignet ist und ein mittels einer Düsennadel (10) betätigbares Ventil (8) aufweist, das im Pistolenkopf (2) nahe der Düsenöffnung (11) angeordnet ist und mit einer Betätigungs- und Rückstellvorrichtung (17, 23) für die Düsennadel (10) versehen ist, ist, damit diese selbstreinigend ist und auch mehrere Komponenten mit abrasivem Material verarbeiten kann, mit einem Düsenkanal (9) versehen, der in die Düsenöffnung (11) mündet. In diesem Düsenkanal (9) ist die Düsennadel (10) verschiebbar gelagert. Des Weiteren weist der Düsenkanal (9) zumindest eine seitlich in diesen eintretende und zur Zuführung der Medien dienende Bohrung (12, 13) auf, die über die dem Düsenkanal (9) im Durchmesser angepasste Düsennadel (10) verschließbar ist. Die Länge der Düsennadel (10) ist dabei so gewählt, dass diese im Ruhezustand zumindest mit der Düsenöffnung (11) der Spritzpistole (1) abschließt.
摘要:
A bulk-solid metering system (10) has a support structure (11). A feed hopper (31) is mounted with respect to the structure (11) and has an upper edge (34). In the improvement, the structure (11) includes an upper member (27) and the upper edge (34) is below such upper member (27). The structure (11) defines a lateral opening (69) sized and shaped to permit the feed hopper (31) to be withdrawn laterally through the opening (69). The feed hopper (31) includes a spout (43) extending therefrom. In a highly preferred embodiment, the lateral opening (69) is positioned to permit withdrawal of the feed hopper (31) in a direction away from the spout (43). The feed hopper (31) is configured to promote very good mass flow as well as to permit agitation in that, in one embodiment, it has a body (37) made of flexible material. There is a hopper upper flange (35) and the spout (43) is spaced below such flange. The body (37) has a first cross-sectional shape, e.g., circular, adjacent to the upper flange (35) and has a second cross-sectional shape, e.g., ellipse-like, intermediate the upper flange (35) and the spout (43).
摘要:
Discharge means comprising a liquid conduit (24) for discharging liquid from a container (10), at least one mouth (38) through which liquid to be discharged can pass into the conduit (24), and level follower means (26) to ensure that the mouth is moved to follow the level of the liquid in the container (10) as that level changes. Relative mouth-level adjustment means (40) are provided to adjust the level of the mouth (38) between a position in which it is below the surface of liquid in a container (10) to a position in which it is above that surface. The relative mouth-level adjustment means (40) comprise at least one float (40) having a selectively variable displacement.
