Patent EP-0311253-A2 (EP)
Inventor: CHILTON DAVID CHARLES
IPC: G01N3/42
Filed: 1988-09-05
Abstract: To ascertain when individual foundry moulds and cores, bonded by a chemical method, have reached the requisition hardness, or still have the requisite hardness, a probe 6 is pushed into the mould or core with a predetermined force, then withdrawn, and after a time interval it is pushed into a fresh point on the mould or core. This is repeated a number of times, each time in a different place, until the penetration is less than a predetermined value, indicating that the requisite hardness has been reached. 
     Apparatus for doing this automatically can be portable and may signal by lamp and/or sound when the hardness has reached the required value. It may be modified to check whether the hardness of a core or mould made some time earlier has fallen below a given minimum value.

Abstract: The all plastic can includes an upwardly extending open mouth portion (20) with an inwardly tapering exterior surface (21) and a molded plastic end closure member (30) having an integrally formed rim portion (40) extending downwardly therefrom. An outwardly tapering interior surface (42) is provided on the rim (40) and is inclined to mate with the inwardly tapering exterior surface (21) of the open mouth portion (20) of the can body. Relative rotation is imparted between the end closure member (30) and the product filled can body so that spin-bond sealing connects the inwardly tapering exterior surface (21) of the open mouth portion (20) and the interior surface (42) of the rim portion (40) of the end closure member (30). An integrally formed outwardly extending rib (22) is provided on the inwardly tapering exterior surface (21) of the open mouth portion (20) to enhance the spin-bond between the end closure member (30) and the can body. A bead of hot melt material (50) is applied around the upper portion of the inwardly tapering exterior surface (21) of the open mouth portion (20) and serves to prevent entry into the interior of the product filled can body of any plastic dust particles generated by the spin-bonding of the end closure member (30) to the can body. The spin-bonding of the end closure member (30) provides a tamper evident closure for the can.

Abstract: A method is disclosed for restricting the delivery and receipt of electronic messages which are delivered to selected recipients via a computer network. Each individual message or individual component of a multiple component electronic message is transmitted in association with an electronic message profile which may include restrictions designated by the transmitter with respect to the recipient's security classification, management level, or address. Preferably the electronic message profile will also include identifying information with regard to the source and type of message associated therewith. Each electronic message profile is then used to automatically control the delivery and receipt of its associated electronic message by comparison with a recipient profile which was previously established. In this manner a transmitter may specify that delivery of a selected electronic message or selected component of an electronic message should be automatically cancelled unless the recipient meets a specified security clearance, management level, or other criteria. Similarly, a recipient may select a profile which precludes receipt of any electronic message from a particular source or of a particular type.

Abstract: A process and apparatus for the continuous separation of electrically charged macromolecular compounds, such as proteins, by forced-flow membrane electrophoresis is provided. 
     Said process is conducted in an electrophoretic cell comprising a membrane compartment, divided by a micro- or ultrafiltration membrane (1) into a feed (2) and permeate cell (3), and electrode compartments (6, 7) being partitioned from the membrane compartment with ion-exchange membranes (8, 9), which are impermeable to the macromolecular compounds, and have virtually no permeability to salts. 
     The electrophoretic process comprises the steps of recycling a mixed solution of the charged compounds which are dissolved in a separation buffer through the feed cell, subjecting of the solution to a pressure-­driven membrane separation, applying an electric field across the membranes and the solution to cause electrophoretic migration of the charged compound and to separate them, and withdrawing the charged compounds thus separated. 
     The process achieves separation of charged compounds having differences of their isoelectric points in a range of as low as 0.1 to 0.2. The process is very useful to remove charged contaminants from the desired compounds.
