Title: Flat top end closure for liquid containers
IPC: B65D5/06
Filed: 1988-06-10
Abstract: There is disclosed herein a flat top end closure (12) for a liquid carrying container, which includes two oppositely disposed, overlapped outer closure panels (40, 42), a folded over panel segment (64) on one of them, and two oppositely disposed, fold-in panels (44, 46), one of which serves as the pour spout when opened. Each of the fold-in panels includes a plurality of score lines, permitting each of the fold-in panels to be folded into two four layer thick portions beneath the outer closure panels such that no raw edge is adjacent the liquid contents. First (50) and second (106) lift tabs are formed on the edges of one (42) of the outer closure panels and the pour spout fold-in panel (44), respectively. Diagonal opening-assist score lines (54, 56) are formed on the outer closure panels adjacent the pour spout.

Filed: 1989-06-20
Abstract: Fragrance releasing pull-apart sheets may be more

Patent EP-0395810-A3 (EP)
IPC: H01H13/50
Filed: 1989-08-24
Abstract: A snap action switch (20) comprises a contact (26) 
having a cut-out tongue (31) mounted on a post (37) with 
the tongue (31) bent to form a spring, the post being one 
terminal (23). The other end (35) of the element remote 
from the tongue end (32) initially contacts an exposed 
second (24) or third (25) terminal above or below the 
other end.  
     When the actuator or nose (44) from a resilient body 
acts against the surround adjacent the tongue end (32), 
force is exerted against the contact. As a result the 
contact snaps from the initial connection between the 
nose (44) and one of the second or third contacts (49 or 
50) to the other. When the resilient body is relaxed to 
permit the nose (44) to resume its original position, the 
switch snaps back to resume connection between the post 
(37) the initial connection with the second or third 
terminal (24 or 25).  
     The disclosure includes an incipient form (69) of 
the snap action switch; and also a method of making the 
incipient form (69) and the switch (20).

Title: Process and device for separating electrically charged macromolecular compounds by forced-flow membrane electrophoresis
IPC: C07K1/26
Filed: 1989-11-09
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.

IPC: G01N33/48
Filed: 1990-04-26
Abstract: A sample of a body fluid, such as 
blood, is collected in a cartridge (12) 
having a sample chamber for storing 
the sample and one or more calibration 
chambers (20, 24), each for storing a respective 
calibration (42, 44) fluid. The fluid sample is 
drawn into the sample chamber by 
placing the sample chamber in fluid 
communication with a needle (16) inserted 
into the fluid sample and applying a 
vacuum (14) to the chamber using either a 
syringe or internal vacuum. A body fluid 
sample may also be drawn into the sample 
chamber from a syringe or capillary 
tube (130) containing the fluid sample. The 
cartridge may be either planar or 
cylindrical. The chambers of a cylindrical 
cartridge may be either elongated 
voids symmetrically positioned about the 
longitudinal axis of the cartridge or 
axially spaced annular voids. One or more 
sensors (50), such as ion-sensitive 
electrodes, are placed in contact with 
the fluid sample and callbrating fluid(s) by 
either placing the sensor(s) in contact 
with externally accessible chambers or by 
allowing the fluid sample and calibrating 
fluid(s) to flow from the chambers past 
the sensor(s). In the event that the sensor(s) 
are placed in direct contact with 
externally accessible chambers, the sensor(s) 
may be scanned from one chamber 
to the next by an automatic drive mechanism.

Title: Electronic ballast
IPC: H05B41/282
Filed: 1991-01-17
Abstract: An electronic ballast for low-pressure discharge lamps supplied from DC or AC voltage networks, having an invertor (1) which supplies at least one lamp (8) via a capacitive reactance (6) connected in parallel with it and an inductive reactance (2) connected in series with it, an electronic harmonic filter (4) with a step-up inductor (L3) and a digital control circuit (2) for the invertor, which control circuit is connected to a DC voltage supply circuit (3). The DC voltage supply circuit is connected to the harmonic filter and has a capacitor (C3) which can be charged to the supply voltage of the control circuit via a first transistor (T4). The first transistor switches on immediately after the supply voltage of the electronic ballast has switched on. A blocking circuit (R6, R7, C4, T5) switches the first transistor off once the capacitor is charged and the latter is continuously recharged via an additional auxiliary winding (N1) of the step-up inductor and a rectifier circuit (D1-D4) connected thereto. In consequence, the voltage required to supply the control circuit is made available immediately after the start, in the case of both DC and AC voltage operation. <IMAGE>
