Title: Roller shutter, in particular for openings of vehicles such as fire protection vehicles
IPC: E06B9/56
Filed: 1987-07-08
Abstract: In a roller shutter (1) for openings, in particular on vehicles such as fire protection vehicles, there are provided two lateral guide rails (2) in which the individual roller shutter panels are guided at their ends by means of slide blocks. The guide rails (2), which have essentially a U-shaped design in cross-section, possess at the outsides of the U-leg and at the U-base longitudinal recesses (4, 6) for receiving component parts, such as roller shutter switch (5) and/or covering strip (7). A longitudinal recess (8) can also be provided on the inside of the U-leg, so that a sealing strip (3) can be releasably attached. Thus, simple fastening elements for individual component parts of roller shutters are provided, and these have an additional increase in the bending stability of the (light-weight) guide rails (2). <IMAGE>

Title: Dual feed bushing for multi-cavity injection molding
IPC: B29C45/28
Filed: 1987-10-08
Abstract: This invention relates to an improved valve pin bushing (42) for a multi-cavity injection molding system. The valve pin bushing has a central bore through which the valve pin (60) extends. The melt duct (120) extends through the bushing (42) to join an enlarged portion (66) of the central bore around the valve pin (60). In the bushing according to the invention, the melt duct (120) branches into two arms (128, 130) with smoothly curved bends which lead to opposite sides of the valve pin (60). This avoids the problem of streaking and slow melt flow on the opposite side of the valve pin.

Patent EP-0283325-A3 (EP)
Title: Reversible drives, and ventilating fans employing such drives
IPC: H02P23/00
Filed: 1988-03-21
Abstract: A periodically-reversing electric drive consists of a single-phase 
split-phase capacitor starter motor (M1) in combination with a bi-metal 
type charger switch (SW2). The switch initially causes input power 
to be applied to the running winding, and the capacitor provides out-of-­
phase power to the starting winding. When the bi-metal heats up the 
switch changes over, the starting winding now acting as the running 
winding, and vice versa. The bi-metal then cools, the switch changes 
back, and the cycle repeats.  
     A ventilator motor driven by such a device tends to eliminate 
dead spaces and improve ventilation.

Title: A data recording disk file with digital servo control
IPC: G11B21/08
Filed: 1988-08-16
Abstract: A data recording disk file with 
a voice coil motor (VCM) actuator (40) 
and a digital servo control system for 
positioning the read/write heads (30, 32, 34, 36) 
to selected concentric data tracks includes means for calculating the 
factor relating acceleration of the 
heads (30, 32, 34, 36) to VCM input current. This 
permits each disk file to compensate for any variation in the nominal 
VCM physical parameters, thus enabling VCMs to be manufactured to 
less demanding tolerances. The disk file also calculates a unique 
acceleration factor for each head position 
during movement of the heads (30, 32, 34, 36) 
from one track to another, thereby improving the arrival time of the 
heads (30, 32, 34, 36) to the target track. During 
an initialization procedure, the disk 
file performs a track seek, during which VCM current and head velocity 
information are acquired and used by 
the microprocessor (80) in the digital 
servo control system to calculate a value representing an average actual 
acceleration factor unique to that disk file. This value, together with 
predetermined constants representing the characteristic relationship of 
acceleration factor to head position in a disk file with a nominal VCM, 
are used by the microprocessor (80) to calculate the actual acceleration 
factor for each head position during a track seek.

Abstract: The invention relates to a process for repairing railway fastenings on wooden sleepers. After removing the old sleeper screw, which becomes loose in the course of time due to rotting of the wood, a thread is cut into the passage holes (11) of the ribbed sole-plate (2). New sleeper screws (33) with a single or double thread (37, 39) having a greater volume than the thread of the old sleeper screw are screwed into the boreholes (11) of the sleeper (1). One thread (37) of this single or double thread (37, 39) has a larger outside diameter that the passage hole (9) of the ribbed sole-plate (2). This thread (37) is matched to the thread (30) cut into the ribbed sole-plate (2). To permit simple guiding of the new sleeper screw (3) into the borehole (11) of the sleeper (1), the old cut-in thread (12) is used for guiding a thread cutter when cutting the thread (30) into the ribbed sole-plate (2) and for the new sleeper screw (33).

Title: Cache memory simultaneously conducting update for mishit and decision on mishit of next address
IPC: G06F12/08
Filed: 1990-06-20
Abstract: In a cache memory simultaneously conducting 
updating for a mishit and a decision on a mishit for the 
subsequent address, a write flag (15) generated by a 
control unit (18) is written in a valid flag field (9a). 
Based on this method, during an access to an external 
memory at an occurrence of a mishit, a tag field (6a) 
and the valid flag field are simultaneously updated. 
When updating a data field (8), a read operation is 
achieved on the tag and valid flag fields to decide 
occurrence of a mishit. Thus, an external memory access 
for a mishit at a next address can be executed at an 
earlier point of time. Moreover, by the provision of a 
data latch (21) disposed for an output from the data 
field, and by reading data at a next address and keeping 
it in the data latch (21) during a memory read cycle 
(C1, C3), succeeding hit data can be outputted 
immediately after a mishit processing is completed. 
Furthermore, also in a cache memory having a plurality 
of tag fields (6a, 6b) and a plurality of valid flag 
fields (9a, 9b), the updating for a mishit and the 
decision on a mishit for a next address can be attained 
at the same time.
