IPC: G05B19/23

Abstract: A drive (32) system includes a single stage gear reducer 
end power screw (32), a brushless variable-speed electric 
motor (12) with position and velocity sensing instrumenta­
tion, a solid state power amplifier, and a programmable 
controller. During operation an absolute positional reference 
is established when the slide actuates a non-contacting limit 
switch to signal that the slide is within less than one motor 
revolution of the correct starting point. A memory accessible 
by a microprocessor has paired values of velocity and 
position stored in a table representing ideal such values for 
deceleration portions of the motion cycle. Alternatively, the 
microprocessor computes each new value of position and 
velocity in real time as required to update the velocity 
commands sent to a comparator. The comparator compares 
the predetermined slide position to the actual slide position 
and signals the microprocessor that a change in output to the 
motor power supply is required. A digital to analog converter 
converts the motor velocity signal that issues from the 
microprocessor to a variable d.c. voltage whose magnitude 
varies over a range that determines the sense of direction 
and speed of the drive motor.

Title: Serial printer provided with cutter
IPC: B41J11/70
Filed: 1982-02-13
Abstract: Serial printer provided with cutter, the printer being of the type in which printing is performed by a printing head mounted on a carriage sliding on guides parallel to the printing line and a continuous printing support moves perpendicularly to the direction of such guides leaning against a substantially vertical platen. A rotating cutter is lever mounted on the carriage over the printing head in a position very close to the printing line and it can be actuated in order to partially overlap a cutting edge of the platen, the edge being parallel to the printing line.Owing to the printing head movement along the printing line the rotating cutter, when actuated operates the transversal cutting of the continuous form.The cut form is disposed in a collecting drawer behind the platen owing to the movement imposed by the rotating cutter and to the reduced thickness of the platen which constitutes a drawer wall. A transparent elastic leaf coupled to the lever on which the rotating cutter is mounted assures the form steadiness during the cutting by pressing it against the platen near the cutting zone.It further provides an elastic reaction which brings the rotating cutter in rest position when it is not actuated to be in cutting position. The leaf does not hamper print visibility nor does it hamper the loading of the form in the printer when carriage is at its end of travel position.

IPC: G06F3/023
Filed: 1982-03-17
Abstract: A device for facilitating non-verbal communications 
between individuals. The device includes a two-sided panel 
containing a plurality of message blocks which are selective­
ly illuminated by the individuals in a variety of modes. In a 
first mode, the message blocks are sequentially scanned in 
one of two patterns, with scan direction and termination 
being controlled by actuating a switch. In a second mode, a 
transparent, direct select keyboard is placed over the mes­
sage blocks and individual message blocks are selected by 
touching the keyboard in front of the block to be selected. 
Finally, the position of the illuminated message block may be 
controlled by a joy stick. The message blocks on the panel 
are printed on removable overlays which are specially 
adapted for various situations. The overlays carry identifying 
markings which are automatically read by the device so that 
the messages on the overlay, which are stored in non-­
volatile memory, can be correlated to their position on the 
panel. The overlays include a number of special function 
blocks which, when selected, cause the device to operate a 
wheelchair, sound an audio alarm, communicate with a 
computer or other device through a serial I/O port, or 
communicate ultrasonically with external devices. Each 
message block may include several different messages, with 
the message selected in that block being designated by a 
corresponding level-selection block. The messages may be 
either letters or words, and the combination of letters and 
words may be accumulated in an alphanumeric display or a 
printer.

IPC: E05B21/06
Filed: 1982-05-10
Abstract: Cylinder locks (1A, 1B) for use in the locking of doors (2) on opposite sides of a vehicle, each have a single barrel (15; 30) which carries tumblers (16; 31) that abut internal shoulders (23) of the lock casing (7) to obstruct turning of the barrel (15; 30) in an unlocking sense (different for the two locks) until the tumblers (16; 31) are withdrawn into the barrel (15; 30) by initial turning of an inserted key (5). The barrel (15; 30) in each case is free to turn in the opposite, locking, sense without any obstruction, turning in both senses being opposed resiliently by a coiled spring (24; 40) that embraces a spindle (10) of the barrel (15; 30) externally of the casing (7). The tumblers (16) of one lock (1A) are spaced by a bush (18) forwardly within their barrel (15) as compared with the tumblers (31) of the other lock (1B) so that different sets (A, B) of the cuts (38) of the common key (5) engage the tumblers (16, 31) of the two locks (1A, 1B).

Abstract: A circuit for generating pulse waveforms having variable 
duty cycles including a counter (11) which counts machine 
cycles (each of which includes a plurality of pulse intervals) 
and clears to zero when the count reaches a first prescribed 
value. A plurality of registers (12A, 12B, 12C) store data 
corresponding to the required duty cycles of a like plurality of 
output pulse waveforms, and a single comparator (13) 
compares the count with the contents of these registers in 
different ones of the pulse intervals of each machine cycle. A 
plurality of output flip-flops (17A, 17B, 17C) are connected to 
be controlled by the counter and the comparator so that each 
is reset in the appropriate pulse interval of a machine cycle in 
which the count reaches the content of the associated 
register and set in the appropriate pulse interval after the 
counter is cleared to zero.

Abstract: The class of weakly basic molecules which are at least 
partially soluble in water, and which are at neutral pH (7 to 
7.5) partially or totally under basic form, electrically neutral, 
gaseous or liposoluble, and which have a pKa greater than 
the lysosomal pH (5 to 5.5) and which are neither virucidal 
nor generally cytotoxic provide an important new class of 
antiviral agents which are capable of inhibiting the pene­
tration of viropexis-penetrating viruses, such as vesicular 
stomatitis virus (VSV), into the cytoplasmic matrix of target 
cells which are contacted with the anti-viral agent, prefer­
ably before the cell is contacted with the virus. These anti-­
viral agents do not have any anti-viral effect on fusion-pene­
trating viruses and, therefore, these anti-viral agents pro­
vide a valuable tool for screening viruses by their cell pen­
etrating mechanisms as well as for their own potential ther­
apeutic value.

tively. Once frame synchronization (Q₂ = 1) is established 
the signals are only gated (13) to the receiver (11, 12, 20) 
during a window interval which is coextensive with that of 
the received bursts.
