摘要:
Disclosed herein is two-stage mat for dispensing volatile materials. The mat is comprised of two materials varying either in thickness, thermal conductivity and/or porosity (and coated with like volatile material), or coated with volatile materials having different vaporization pressures. In either configuration, the mat provides for both an instant burst of volatile and then a sustained vaporization of volatile. Methods of using such mats are also disclosed.

A two-piece, modular valve manifold adapted to be positioned between a main flowline and a pressure sensor to control fluid flow from the main flowline to the sensor, the manifold comprising a first module that adapts to a pressure sensor, such as a differential pressure transmitter, and a second module that is connected to a source of process fluid, the second module containing a block valve system, the first module containing an equalizer valve system and a vent valve system, the modules being connected together whereby process fluid can be transferred through the first module to the second module and ultimately, to the pressure sensor.

A flexible pressure-sensitive food grade wrap film, and a process for manufacturing the film. The film includes a substrate overcoated with a pressure-sensitive adhesive, a release overprinted on the adhesive that prevents the adhesive from clinging to the surface of an article or to itself without applying pressure, and, optionally, a release coating on the opposite side of the substrate. Once pressure is applied to the film, the film flexibility allows the adhesive to contact the surface of the article or itself and subsequently adhere to hold the film in place or to form a sealed pouch around an article. The pressure-activated contact and adhesion to an article or to itself are designed to form a tight, spill-resistant physical bond that seals liquid or solid contents in a container, or forms a sealed pouch around a solid article.

A manifold assembly (10) for operating a safety relief valve (12) includes a manifold block (60) having a block inlet port (230), a block dome pressure port (232), and a pair of control cavities (220 and 222) each adapted for receiving a pilot valve (70) or auxiliary control member (80). Inlet control valves (74, 84) dome pressure control valves (76, 86) and test control valves (78, 88) are each mounted on the manifold block. One of the pilot valves may be maintained on-line for controlling operation of the safety relief valve, while the other pilot valve may be isolated for service. A cartridge pilot valve assembly (70) includes a bushing (126) for facilitating installation and removal of the cartridge valve assembly from the valve block. An improved metal washer (122) is provided having inner and outer knife edges (330, 334) for sealing engagement between the valve body (110) and the block (60).
摘要:
A mitt (1) worn on a hand for cleaning. The mitt (1) includes a section (20) for the palm of the hand, a section (30) for the fingers, and a compartment (40) on either side of a central axis of the mitt for a thumb. The mitt (1) is capable of being used on either the right or the left hand, and both sides of the mitt (1) may be used without moving the mitt (1) from one hand to the other. The mitt (1) is formed using an electrostatically-charged material, a material capable of acquiring a triboelectric charge, or a material that is treated with a tackifying agent in order to optimize cleaning efficiency. Also disclosed is a method of forming a mitt for cleaning.
摘要:
A medication infusion device such as a programmable infusion pump includes data input regarding a selected patient parameter such as a current blood glucose reading. The infusion device includes a controller responsive to this data input to develop a medication delivery protocol which can be implemented automatically, recommended via a display for subsequent approval or rejection upon manipulation of control switches, or otherwise overridden in favor of a different medication delivery protocol.
摘要:
The invention relates to a method of servicing lodging rooms (A) and the like, in which a trolley (1) is used containing materials for servicing. The trolley is driven to the room and parked there. The servicing person removes from the trolley (1) a smaller sub-trolley (8) containing the required servicing materials and is entering the room (A) with this sub-trolley. The trolley (1) comprises a frame (2), a chassis (3, 4) under the frame for moving the trolley, and supports (5, 6, 7) for supporting materials for servicing. A smaller sub-trolley (8) is removably connected to the trolley (1) and comprises supports (17, 18, 19) for at least the servicing materials required for one room.
摘要:
A method is described for supplying management services from a service centre for a plurality of industrial cleaning processes or machines at remote sites and/or operated by different organisations. A local unit is provided at each process or machine, which is programmed to forward process/machine information with a process/machine identification to the service centre. The information received from the local units is processed in a service centre computer to obtain management reports on the process or operation of the machines. In a system for monitoring a plurality of industrial cleaning processes or machines operated by at least one organisation, each process or machine uses a local unit with a plurality of sensors for sensing operating parameters of the process or machine. A service centre computer operated by a service organisation at a location remote from the location(s) of the local units is programmed to make a connection to a local unit and to obtain operating parameter data from the local unit periodically.
摘要:
A decorated luminary product includes either a candle (or other light source) or a holder for containing the candle (or other light source), having a mirror film adhered thereto to provide a pleasing visual effect. A decorative web of a polymeric mirror film web is preferably heat shrunk to conform to the shape of the candle or the holder. The mirror film is located to cooperate with light emitted by a candle or other light source to augment the visual effect created when the candle is lit, by providing birefringent effects, changes in coloration in accordance with changes in viewing angle, and variations in both reflectivity of ambient light and transmission of light from the candle or other light source.
摘要:
An insecticidal bait dispenser (20) is provided having a stack of insecticidal bait pellets (28) disposed therein that are mechanically connected to one another. The outermost pellet is exposed through an opening at the outer end of the dispenser and includes a mechanical fastener (36) that allows the pellet to be attached to, for example, a wall (54). After the outmost pellet has been punched against the wall to stick it to the wall, it may be cracked apart from the stack of pellets with a simple jerk of the dispenser.
