Abstract: ABSTRACT OF THE DISCLOSURE:      On the circular periphery of a winding shaft, flat recesses are formed at fixed intervals both in the axial and circumferential directions, with small rollers mounted one each on the flat recesses rollably on and inseparably from the flat recesses.  A spool for winding a strip of sheet material thereon is slid over the circular periphery of the winding shaft sidewise from one end of the winding shaft.  A slight rotation of the spool relative to the winding shaft causes the aforementioned rollers to be moved and wedged into the gap between the spool and the winding shaft, with the result that the spool and the winding shaft are locked to each other.

Abstract: TITLE OF THE INVENTION     Heating Process and Its Apparatus in Reducing Air Pressure Within a Chamber at a Balanced Level ABSTRACT    This invention relates to a heating process and its apparatus in reducing air pressure within a chamber at a balanced level.  The air retained within the chamber or the air suctioned through an outer air suction means is suctioned forcibly by rotation of rotary means disposed in the chamber and discharged outside the chamber through an inner air discharge means until air pressure within the chamber is reduced to a balanced level.  Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the interior of the chamber is heated by air friction heat.  And, a cooled outer air suctioned by the outer air suction means is heat-exchanged with a heated air energy discharged by the inner air discharge means.

Abstract: Title:          A DC-to-AC voltage converter having galvanically separated input and output(s).     Abstract of the disclosure:  A DC-to-AC voltage converter for the supply of power to at least one load, comprising an input circuit and at least one output circuit gal-vanically separated from said input circuit, and a converter transformer. According to the invention a primary winding of the converter transformer is series-connected to a switching transistor, which series circuit arrange-ment is connected between a positive input terminal and a negative input terminal, with one or more resonance capacitors being connected in parallel with the collector-emitter circuit of the switching transistor and/or in parallel with said primary winding. Control devices are provided for said switching transistor, with the resonance capacitor(s) and said primary winding being dimensioned so that, under all anticipated  load conditions of the converter, including short-circuiting of the output circuits, the control devices cause the voltage across the collector-emitter circuit of the switching transistor, after the latter has become non-conductive, to fall back to a very low value before the switching transistor is again driven into the conductive state. The converter transformer has a first auxiliary winding strongly coupled with said primary winding and, at least in part, provides the driving power required for the switching transistor.          A time-delay and turn-off circuit is energized and synchronized by at least one second auxiliary winding of the converter transformer, and 2 smoothing circuit provides the driving rower for turning off the switching transistor, which driving power is withdrawn from a third auxiliary wincing of the converter transformer.

The commands are formatted to identify the command functions and the ports at which the switching and control actions are to be carried out.  These ports may be provided by separate modular switching units, each having processors for carrying out the switching functions at the designated ports and for distributing the commands in accordance with the command format to the designated port regardless of which of the modular switching units has the port.  Responses as to the execution of the switching events are also conveyed to the host computer in a format which designates the response function and the port at which the function occurred.  The switching units may be equipped with asynchronous serial data links for connecting one or more host computers or devices to the modular switching peripheral units.

Abstract: Progressive Safety Abstract A safety device for stopping an elevator car or counterweight has a brake shoe 5 on one side of a guide rail 3, and, on the other side, two leaf springs 11,12 and a roller 8.  The springs 11,12 define a tapered area 22, and the roller 8 is pulled by a governor to engage the rail 3, which trips the roller, causing it to be forced into the tapered area and forcing the brake shoe 5 against the rail 3.  The roller engages a soft metal stop 16 when the device is operated, and this stop is worn away during each operation, which permits the roller to move higher on each operation; this compensates for any wear on the brake shoe.  The governor is attached to the car or counterweight.
