Patent EP-0293250-A3 (EP)
IPC: B29C39/26
Filed: 1988-05-27
Abstract: An elongate packing 7 is sandwiched between two sheet-like 
mold members 1, 2 in an encircling manner to define a mold cavity 
therebetween, then a thermosetting plastic material 9 is poured 
into the mold cavity, and the thermosetting plastic material is 
heated and set in the mold cavity. The upper and lower mold 
members are held against deformation transverse thereof so as not 
to be deformed by the shrinkage of the thermosetting plastic 
material when the latter is set, and the packing is allowed to 
move transversely thereof for following the shrinkage of the 
thermosetting plastic material when the latter is set. In some 
embodiments, the packing comprises a packing body 11 adapted to be 
sandwiched between the mold members for preventing the plastic 
material from flowing out of the mold cavity, with a flange 12 joined 
to the packing body and adapted to be held against peripheral 
edges of the mold members.

IPC: D04H3/04
Filed: 1989-02-22
Abstract: A stand-alone machine and a process for forming crosswise filaments (1) for non-woven fabric comprises two sets of non-traversing edge spacing pins (2), each set with a gripper (14, 16), and a traversing set of slider pins (3). The sets of pins (2, 3) are placed close together. Crosswise filament (1) yarns are engaged by these sets of pins (2, 3). The slider pins (3) then traverse and pull the filaments (1) to their full length. The crosswise filaments (1) are cut and fixed to edge elements (4, 5, 11), which preferably may include adhering the crosswise filaments (1) to selvage filaments (11). The edge elements (4, 5, 11) are then separated to draw the crosswise filaments (1) to their full width. The invention provides increased speed, precision, and flexibility in making crosswise filaments (1) for non-woven fabrics.

Abstract: This invention relates to an injection molding system having two heated nozzles mounted in tandem. The rearward nozzle (12) is considerably longer than the forward nozzle (10) and has a melt bore (90) which is considerably larger in diameter than the melt bore (44) of the forward nozzle. The smaller forward nozzle (10) has a backplate (74) secured to its rear end (48) with a thin flanged portion (76) which extends outwardly and rearwardly into bearing contact against a rearward mold core (16) to secure the forward nozzle (10) in position in a well (22) in a forward mold core (14). The rear face (84) of the backplate (74) has a seat (82) extending around the melt bore (80) to receive a cylindrical forward portion (106) of a gate insert (100) mounted on the forward end (96) of the rearward nozzle (12). Thus thermal expansion of the larger rearward nozzle (12) is taken up by the forward portion (106) of the gate insert (100) sliding in the seat (82). The smaller forward nozzle (10) has a portion (56) of the electrical heating element (52) extending into a forwardly extending nose portion (24) which provides sensitive temperature control in the gate (34) area.

Title: Protective circuit for magnetoresistive element
IPC: G11B5/39
Filed: 1989-09-20
Abstract: The invention relates to a protection circuit for a magnetoresistive 
(MR) element (Rh) having a first terminal and a second terminal in which 
a first current source is coupled to the first terminal of the MR element 
to produce a bias current (J1) through the MR element and a second 
current source is coupled to the second terminal of the MR element to 
produce a reference current (Iref).  
     According to the invention, circuit means (R,R,B) coupled across the 
MR element (Rh) senses the centre potential of the MR element 
substantially midway between the first and second terminals, and a 
feedback circuit (B) responsive to the sensed centre potential adjusts 
the current output of the first current source (J1) to maintain the 
centre potential to a selected reference voltage (Vcentre) to protect the 
MR element (Rh) from short circuits to a conductive area 
of the magnetisable recording medium being read by the MR element.

Title: Reference cell for evaluating the turbidity of liquids
IPC: B01L99/00
Filed: 1990-01-14
Abstract: A reference cell for evaluating the turbidity of liquids, in particular of emulsions. In evaluating whether the oil content of an oil-containing liquid to be purified is still below a permissible value, a comparison is made with a reference liquid in a cell. Said reference liquid, which is generally also an oil-water mixture, demulsifies with time, resulting in uncertainties in the assessment. In the new reference cell, at least one transparent hollow cylinder has a predetermined light scattering power corresponding to a predetermined turbidity value. Errors due to a decomposing liquid can no longer occur. Evaluation of clarified oil-water mixtures. <IMAGE>

the cipher-key generated by said first cipher-key generating 
means, on the basis of the key distributing code and 
identifying information from said receiving means, the 
constant from said constant holding means and the secret 
information from said secret information holding means. This 
system avoids excessive overheads on both the sending and 
the receiving parties if a cryptogram is to be sent by an 
existing mail system, and improves the security for the 
authorized use.

Patent EP-0573291-A3 (EP)
IPC: G11B23/00
Filed: 1993-06-03
Abstract: A cartridge provided with a case for housing an 
optical disk so that it can be driven and rotated. A 
recessed section is formed around the peripheral edge of 
the center hole of the optical disk. A hub, which is used 
for clamping the optical disk by the use of a magnetic 
force, is formed into a hat-shape, and it is placed at the 
recessed section. The height of the hub is set to be 
greater than the gap between the optical disk and the 
cartridge case. Without the necessity of fixing the hub 
to the disk, this arrangement makes it possible to prevent 
the hub from coming off from the recessed section. Thus, 
the arrangement eliminates the fixing process between the 
hub and the optical disk as well as maintaining the 
clamping function of the hub, thereby making it possible 
to reduce the manufacturing cost.
