Patent EP-0369777-A3 (EP)
Title: Method and apparatus for closing cartons
IPC: B65G47/244
Filed: 1989-11-15
Abstract: An apparatus for closing lidded cartons (9) has a turning station (36) including a flightless horizontal conveyor, and a chain conveyor (80) which extends along one side of the flightless conveyor (44) and has light restraint members (86) pivotally mounted on its links (84). The chain conveyor (80) is moved in the same direction as the horizontal conveyor, but at a slower speed. Part way along the chain conveyor an upwardly directed air jet (100) moves the restraint members (86) individually but in succession to temporary raised positions in which they are available for engagement by a carton (9A) which is moving along the flightless conveyor in overlapping relation to the chain conveyor. A restraint member engaged by a carton in this way thereafter serves as a fulcrum about which the carton pivots through a substantial angle. Plough bars later complete the rotation of the carton through 90 DEG  in total.
Patent EP-0370776-A3 (EP)
IPC: H01L21/304
Filed: 1989-11-21
Abstract: An ink jet printhead fabrication process produces a plurality of printheads 
from two mated substrates (31,36) by two dicing operations. One dicing operation 
produces the nozzle face (29) for each of a plurality of printheads and optionally produces 
the nozzles (27). This dicing blade, together with specific operating parameters, prevent the 
nozzles from chipping and the nozzle faces from scratches and abrasions. A second dicing 
operation with a dicing blade severs the mated substrates into separate printheads. The 
dicing operation which produces the nozzle face is preferably conducted in two steps. A 
first cut makes the nozzle face, but does not sever the two mated substrates. A second 
dicing cut severs the two substrates, but does so in a manner that prevents contact by the 
dicing blade with the nozzle face.

Patent EP-0432673-A3 (EP)
Title: Mobile apparatus for producing active water-based solutions
IPC: A01M7/00
Filed: 1990-12-08
Abstract: In this mobile apparatus (Figure 1), the agent is forced at constant regulable pressure through a pipeline 7 by means of compressed air 1 via a pressurised container 4 serving as active ingredient container.   The flow rate control valve 11 is a needle valve with electrical servomotor and regulates the required quantity of agent which is indicated in the flow rate counter 12 having indicating device 12a. This quantity control is velocity-dependent and can be controlled by means of computer electronics in order to discharge a uniform amount of agent onto the surface. The active ingredient is sprayed into the mixing container 9 via the angled nozzle 8 at a higher pressure than the pressure of the water 9a coming from the water reservoir pump. The cylindrical baffle 10 with inclined slots in the outside wall brings about a homogeneous mixing of the desired solution. Depending on the number (Figure 2) of the angled nozzles 8 used, various active ingredients can be simultaneously fed into the container 9. To prevent contamination of the operating staff, the agent is emptied out of the canister 5 via the filling hose 5a into the agent container 4 through a filling lock. The residual amount of the agent is drained back into the canister via the stopcock 6 and the emptying connection pipe 5a. <IMAGE>

Patent EP-0398528-A3 (EP)
Title: Closure having improved sealant channel for receiving sealant by spin lining
IPC: B65D53/06
Filed: 1990-04-26
Abstract: This relates to a closure combination which 
includes the closure being formed with a sealant 
channel (20) to which there is applied by spin lining a 
plastisol type compound sealant (10), or the like. It is 
preferred, from an economy standpoint, to utilize a 
minimal amount of the sealant while providing the 
necessary sealing surface between a container neck 
finish and the sealant. Since the sealant is 
applied by a spin lining process during which the 
closure (12) is (30) rapidly rotated, the sealant is thrown 
radially outwardly by centrifugal force. However, 
the viscosity of the sealant normally is such as to 
prevent it from being returned to a level-flat 
condition. It has been found that by modifying the 
sealant channel (36) configuration, particularly the slope 
of the base wall (34) thereof, depending upon the viscosity 
of the sealant, one can selectively obtain a uniform 
thickness sealant application or a flat top sealant 
application. Further, by sloping (72) the end seal (70) 
surface of the container to which the closure 
combination is to be applied, one can obtain extra 
beneficial results. It is also desirable to provide 
a dam (40) arrangement for the sealant which permits return 
overflow of the sealant with the dam accommodating the 
overflowing sealant (42).

washing and permeation. This activity endures for a 
couple of days. An excess of isolated hydroxil ion 
(H₃O₂)- occuring in the water likely causes the activity.

Title: Prerecorded cassette for a system for magnetically recording/reproducing signals
IPC: G11B15/06
Filed: 1992-05-04
Abstract: A prerecorded cassette (1) belongs to a system for magnetically recording/reproducing signals on/from magnetic tape in accordance with a standard, which system comprises apparatuses and cassettes compatible therewith, which cassettes comprise two parallel main walls and interconnecting transverse walls and occur with prerecorded tape (prerecorded cassettes 1) and with blank tape (blank cassettes 3), which standard specifies a tape length marking which can be detected by an apparatus and which marks the length of the magnetic tape in a cassette by a pattern of openings (33-37) in a marking zone (39) of a main wall (19) of a cassette (3), which tape length marking comprises a plurality of submarkings (33-37) in a binary multi-bit code, the value of each bit being defined by the presence/absence of an opening. With the prerecorded cassettes (1) a tape length marking is dispensed with completely and information about the playing time and information about the position on the tape are recorded on the tape as time code. Preferably, the system specification for the erase protection is such that, to indicate the impossibility of home recording, the prerecorded cassette does not have an erase protection opening at all. As a consequence, the prerecorded cassette (1) is not suitable, and can hardly be made suitable, for home recording. If the cassette is provided with a permanent label (55) the relationship between the recording and the information on the label will be maintained for the entire life of the cassette.
