Title: Injection molding methods, injection molding apparatus and injection nozzle devices for use in molding multiple-layer articles, and multiple-layer injection molded articles
IPC: B65D1/28
Filed: 1984-04-11
Abstract: For co-molding a plurality of articles from a plurality of 
polymeric materials, a preferred molding apparatus has a 
plurality of valve-controlled co-injection nozzles (296) and 
injection cavities (102). The polymeric materials (A to E) 
are melted and fed from their sources (202, 204, 206) by 
screw extruders (214, 216, 218) to a set of rams (232, 234, 
252, 260, 262) which appropriately pressurize and move 
streams of the polymeric materials to feed blocks (296) each 
associated with or forming part of a respective nozzle (296) 
for injection into the related cavity (102). The streams 
leaving the rams (232, 234, 252, 260, 262) are conveyed along 
respective runner ducts (220, 222, 250, 257, 258) to a runner 
extension member (276) in a runner block (288), and in the 
runner extension each material stream is divided into a 
plurality of branch streams. Each branch stream is ducted to 
flow splitters in the runner block (288) for further division 
into plural feed streams equal in number to the number of 
nozzles (296), and the separate feed streams are then fed one 
to each nozzle (296). The apparatus is configured such that 
for each material, the plural feed streams reach their 
respective nozzles (296) after passage along ductings of the 
same length and geometry to ensure that the streams enter 
their nozzles as nearly as possible in the same condition, 
ready for injection. Each nozzle (296) receives the 
polymeric materials (A to E) as separate feed streams and 
combines them appropriately into a plural-layer, 
plural-material stream for injection. The nozzles all have 
pin and sleeve valves (800, 834) to control admission and 
flow of the different materials to their central channels 
(240) wherein the combined stream is formed. Valve operation 
is under microprocessor control (2040) and the valves - which 
are effectively substantially identical - are coupled to 
common valve actuating cams (850, 856) for operation in 
 
 
unison, so that at any instant in the molding cycle the 
combined streams formed in the nozzles (296) for injection 
are as near as possible identical to one another. By 
appropriately controlling the pressures of the polymeric 
material streams and by appropriately controlling the timing 
of valve operating movements, precise control is obtainable 
whereby e.g. internal layers of the injected articles are 
positioned where best suited depending on the service 
required of the articles.  
     The method and apparatus are applicable to the 
production of injection or injection blow molded articles 
such as container for commestibles and beverages.

Title: Method for charging rechargeable batteries
IPC: H02J7/10
Filed: 1989-02-22
Abstract: In a method for charging rechargeable batteries, especially lead-acid accumulators, preferably in a maintenance-free, sealed design, it is intended that the permissible gassing pressure inside the battery cells should not be exceeded, irrespective of the characteristic used. After reaching an upper limit voltage (UoG) of the battery, below the gassing voltage, the charging current (I) is therefore reduced to a lower value until the falling battery voltage has reached a lower limit value (UuG). In consequence, the charging current (I) is raised again to the upper value which falls slightly with increasing charge. This pulsating charging method is continued until the charging current with the lower value reaches a specific switch-on time (tu,max). Thereafter, subsequent charging takes place with the lower value of the charging current (I) for a predetermined subsequent charging time (tN). <IMAGE>

Patent EP-0468098-A3 (EP)
Title: Pressure transducers and method of manufacturing same
IPC: G01L9/00
Filed: 1990-12-22
Abstract: The invention improves upon the diaphragm/beam-type transducers and method of manufacturing same described in U.S. Patent No. 4,368,575. The new transducers and method of manufacture utilize strips or slivers of silicon or germanium which are larger than the individual strips used in the apparatus and method described in U.S. Patent No. 4,368,575 by an amount sufficient to permit (a) the formation of two gages on each strip and (b) the forming of bonding pads on each gage. The bonding pads are formed on the gage strip before the strip is bonded to the beam, so that formation of the bonding pads and bonding of the strip to the beam can be handled automatically. The strips are mounted to one side of the midpoint of the beams, so that when a diaphragm/beam is deflected by application of a fluid pressure, one of the two gages will undergo a tension strain while the other gage will undergo a compression strain. Because both gages form part of the same silicon or germanium strip, they tend to be virtually identical in physical and electrical properties, thereby simplifying calibration of the resulting transducers. <IMAGE>
