Abstract: A foot pedal controller (1) comprises a pedal (2) 
to which is attached a lever (3) pivotally mounted both 
in a mounting flange (4) and an anchor plate (10). 
Downward force applied to the pedal (2) causing pivotal 
motion of the lever (3) in an operational sense is 
resisted by a tension spring (14) connected between the 
anchor plate (10) and the lever. A flexible cable (18) 
comprises a core (19) translatable within a casing (20). 
The core (19) is operatively attached to the lever (3) by a 
retaining clip (26) which is snap fitted to the lever (3). 
The casing (20) is secured against translational movement 
to the anchor plate (10) by a plug-in cable hub (38) having 
a flange (40) abutting one side of the anchor plate and a 
pair of spring arms (45) which will deform radially 
inwardly when the cable hub is pushed into a receiving 
aperture (47) in the anchor plate and then spring 
radially outwardly to abut the other side of the anchor 
plate. The core (19) can be operated by the foot pedal (2) 
alone by having a lug (22) with an enlarged head (22) 
engaging in a countersink (32) in the retaining clip (26). 
Alternatively, a hand control can be fitted as well in 
which event the core (19) would be extended through the 
retaining clip (26) and a second casing would encase the 
core to a hand control member and have one end seat in 
that countersunk (32), by which either the foot pedal (2) 
or the hand control member can be selectively used to 
translate the core in a pull mode.

Abstract: Method and apparatus for aligning fabric as it 
is advanced in a prescribed direction toward a 
sewing machine (10) such as a double overlock seamer for 
stitching pants. Photosensitive devices (180) sense 
displacement of edges of upper (14) and lower (16) fabric 
plies relative to a desired alignment line. Error 
signals are produced when either ply edge is 
displaced from the desired alignment line. Friction 
wheels (30) (32) responsive to the respective error signals 
guide each ply toward the desired alignment line as 
it is advanced toward the sewing machine (10). Each 
friction wheel pivots about an axis perpendicular to 
the ply and is controlled by a stepper motor (84). Each 
friction wheel is movable between an operating 
position in which it is biased against the 
respective fabric ply, and a retracted position for 
insertion or removal of fabric. The pressure 
applied to the fabric ply by the friction wheel is 
adjustable. A centering device aligns each friction 
wheel with the direction of fabric movement toward 
the sewing machine when no fabric is present in the 
apparatus.

(21) and replaceable, e.g., by woodworking units equipped with other 
tools. The tool spindle (3, 5) is separable from the bearing housings 
(7) for exchanging the tools (4, 6). For ease in removing and replac­
ing the lower woodworking unit (9), the carrier can be pulled complete­
ly out of the machine at one side. For adjusting optimum cutting, the 
lower woodworking unit can be vertically positioned as regards the 
overhang of the tools relative to the working surface (1) of the feed 
table. Owing to the easy exchangeability of the woodworking units and 
the adjustability of the lower woodworking unit, the machine can be 
used both as a planer and as a combined planing-milling machine.

Title: Display signal generator
IPC: G06F3/147
Filed: 1989-08-03
Abstract: A display signal generator for graphic display has a pallet 
(6) or look-up table for converting digital color code data 
into display data. The display data converted by the pallet 
are processed to RGB signals for producing a CRT display 
and, at the same time, are supplied to a flat-panel inter­
face unit, without using an analog-to-digital converter and 
corresponding control circuits. A clock signal synchronized 
with the display data is produced by circuits formed on the 
same semiconductor substrate as the other components of the 
display signal generator. The delay time involved in the 
conversion of the digital color code data into display data 
is also imparted to display control signals such as hori­
zontal and vertical synchronizing signals in order to main­
tain a stable timing relation between the display data and 
the display control signals. The display signal generator 
can be constructed in a smaller size and at lower cost than 
the existing systems and can process the data at a higher 
speed.
