Abstract: A container is arranged to be particlularly suite to food products which are discharged from the container by extrusion through an outlet (14). The outlet shapes the product as it is extruded and is made up of moveable portions (25) whose extent of movement is limited by limiting means (28, 29) so that the portions (25) still lie across the path of product extruding through the opening (14).

Abstract: The invention has application to dispensing dessert products from pre-filled containers. The container (11) has an outlet (12A) and a moveable portion (13) which is engageable to reduce the container internal volume and cause product to be extruded from an outlet. The container is located on a support (15) during dispensing and there are means (48-51, 53) for detecting whether the product is extrudable and/or whether dispensing is complete. In addition, there is a detector (35-37) for detecting a container in a discharge position on the support.

Abstract: The dispensing apparatus of the invention is primarily intended to dispense frozen product from one portion containers (10), usually by extrusion through a circular outlet (13). In order that the product shape (46) after discharge is capable of being ball-shaped the receptacle (40) into which the product is discharged is located to provide resisted discharge of product over at least part of the discharge cycle. By providing resisted discharge the product shape is altered and laterally increased so that a ball-shaped portion of product is received in the receptacle.

Abstract: The invention provides a device for selective molecular recognition, the device comprising a sensing portion, wherein said sensing portion includes a substrate having coated thereon a layer comprising a hyperbranched compound having:

Abstract: An apparatus for collecting particles or vapor from air or surfaces comprising: a housing comprising an inlet open to the air to be sampled and an outlet; and a fan having one or more open areas within the housing capable of being driven at a speed effective to cause collection on the surface of the fan of particles or vapor in the air. A method of collecting a particulate sample from air comprising the step of driving a fan having one or more open areas within a housing comprising an inlet open to the air to be sampled and an outlet, at a speed effective to cause collection on the surface of the fan of particles in the air.

Abstract: The present invention provides a device for selective molecular recognition, the device comprising a sensing portion, wherein said sensing portion includes a substrate having coated thereon a layer comprising a dendrimeric compound having: (1) a core portion; (2) at least one unsaturated arms extending radially from the core portion; and (3) at least one halogen substituted alcohol substituted at the terminus, the interior, or both of each; The device is used to detect the molecules of a hydrogen bond accepting vapor such as organophosphorus or nitroaromatic species.

Abstract: The present invention provides a device for selective molecular recognition, the device comprising a sensing portion, wherein said sensing portion includes a substrate having coated thereon a layer comprising a dendrimeric compound having:

Abstract: Apparatus and method for detecting presence of an analyte in ambient air. The apparatus comprising a valve for admitting ambient air, a line for conveying the air to a sensing element, a housing for isolating the environment around the sensing element, an inlet port for flowing the air tho the sensing element in a turbulent flow in a direction substantially perpendicularly to the sensing element, an outlet port for conveying the air from the sensing element, and a pump in communication with the outlet port for providing suction for drawing the air to the sensing element. The method includes the steps of drawing in ambient air that may contain an analyte, projecting the air at a sensing element in a turbulent flow by flowing the air at the sensing element, the sensing element having on its surface a chemoselective material that selectively interacts with the analyte, and detecting the interaction of the analyte with the sensing element.

Abstract: A frozen confection dispenser includes a collapsible container for the confection such as ice cream and a piston for selectively collapsing the container to extrude the confection from the container through an outlet to a cone or the like.

Abstract: A dispensing apparatus for dispensing a single serving of a viscous or semi-solid product from a container, the container comprising a base, a deformable portion and an outlet, the apparatus comprising deforming means movable to engage and deform the deformable portion to discharge product from the container through the outlet, a seating for supporting the base of the container during dispensing of product from the container, an arm carrying the seating and movable between an operating position and a non-operating position in which the container may be removed from and placed in the seating, and support means for the arm whereby the arm is movable between said positions, the deforming means being engageable with the container only in the operating position.

Abstract: Refrigerated storage apparatus is primarily intended for storing product which can be removed without significant loss of cold air and is suitable for vertical, upright cabinets. The apparatus has a main access door extending vertically and moveable about a vertical axis. Access openings are provided, usually in the door to gain access to products within the storage compartment, the openings being of relatively small size. The compartment houses storage means for product and there may be storage means for each kind of product. Closure means seal off each access opening.

Abstract: A single handpiece that can be used in multiple dental treatments is provided. The handpiece comprises a housing having a coil for producing an electromagnetic or electrostrictive field in the housing, and a number of inserts that react with the electromagnetic or electrostrictive field and can be used with the housing to complete the handpiece. A switching system used with the handpiece, which electrically recognizes the particular insert used with the housing provide for automatically controlling circuitry that determines which of a number of materials and medicaments are to be delivered to the handpiece for use with a particular insert. Circuitry which provides better control of the ultrasonic insert in the handpiece is also provided.
