Title: Automatic machine for carrying out single and double contour pockets with mobile lower platform l-shaped fold-over blade and damper
Inventor: GALLO ANTONIO
IPC: D05B39/00
Filed: 1990-10-16
Abstract: Abstract The present paper describes a machine with a mobile lower platform which automatically produces pockets on articles of clothing. The fabric is held  firmly between the abovelying blades and the lower  mobile platform,  during  sewing operations, in  order  to avoid dragging the fabric across the lower platform which  generally produces sewing defects along  the borders of the pockets. The pressing arm lowered by means  of  a  piston  with  an  adjustable  damper.          Furthermore,  the fold-over blades are L-shaped  in order  to  maintain the fabric stretched  over  the cutting  and  sewing  assembly,  thereby   avoiding wrinkling of the material while it is being sewed.

Abstract: An output buffer circuit which supplies logic signals at an emitter-coupled-logic (ECL) level is realized by a CMOS process. The logic signals are supplied to the gate electrodes of a first P-channel CMOS transistor and a first N-channel CMOS transistor connected in series, and their common drain output is supplied to a second P-channel CMOS amplifying transistor having an open drain configuration. Between the output terminal of the P-channel CMOS transistor and an external power supply terminal is a first resistor. A voltage regulating means, connected between the output terminal and the external power supply terminal, regulates the output voltage at the output terminal. In the voltage regulating means, a voltage setting circuit produces a desired voltage using the voltage on the external power supply terminal. A control voltage generating circuit uses the desired voltage to generate a control voltage which acts through a regulating driver circuit to regulate the voltage at the output terminal.

Abstract: A single circuit for detecting a synchronization pattern in a serial data stream. Subsequent to detecting the synchronization pattern, the single circuit generates the control signals for converting the serial data to a parallel format and loading the parallel data into a first-in-first-out (FIFO) memory.      The single circuit includes a controller arranged to receive the serial data stream. A counter is connected to the controller. When the counter is detecting the synchronization pattern and the synchronization pattern is being received, the counter is incremented. Absent the synchronization pattern being received, the counter is reset to a predetermined starting point. Subsequent to detecting the synchronization pattern, the counter generates a load signal.      The single circuit further includes a pulse generator arranged to receive the load signal from the counter and generate a pulse of duration equal to a bit period of the serial data stream. An indicator is provided which generates an in-synch signal after the counter detects the synchronization pattern.

Title: Apparatus and method for controlling the frequency of vibration of a compacting machine
Inventor: QUIBEL ALAIN J
IPC: E01C19/28
Filed: 1991-04-04
Abstract: Abstract of the Disclosure Apparatus and Method for Controlling the Frequency of Vibration of A Compacting Machine An apparatus and a method are provided for controlling the frequency of vibration of a compacting machine.  The frequency contxol is carried out by the apparatus which determines the actual time at which a ground contacting member of the compacting machine is at its true vertically lowest position.  This is determined by measuring the time at which the vertical acceleration of the ground contaoting member has a maximum value during one rotation of an eccentrically mounted, vibration inducing mass.  The time difference between the tims at which the vibration inducing eccentric mass is at a predetermined position and the time at which the acceleration of the ground contacting member is at the maximum value is used to calculate a phase angle relationship (?) between the ground contacting member and the eccentrically attached member.  This method of determining the phase angle relationship (?) between the two members provides an accurate parameter for controlling the frequency of vibration imparted to a compactible material by the compacting machine.
