Abstract: Abstract A radio transceiver is disclosed having manual controls on a microphone and the remainder of the circuitry located in a main chassis.  The microphone and chassis are connected by means of a multiconductor cable, and time sharing multi-plexing techniques are utilized and serially transmit infor-mation, bidirectionally, along a common data line while a clock line is utilized to synchronize the operation of main chassis and microphone circuitry. Multiple bit binary coded digital words are sent to the microphone to activate micro-phone displays while analog signals are sent from the micro-phone to the main chassis to provide analog control signals for the transceiver.     A digital synchronizing pulse detector is disclosed for use in the above transceiver multiplexing system.  The detector identifies synchronizing pulses which occur in the clock signal wherein the identification insures the syn-chronization of microphone and main chassis circuitry.     The transceiver provides for designating a subset of all of the available communication channels as desired channels, and in a memory mode the transceiver is tuned only to those desired channels.  Distinctive visual displays are produced indicating if any channels have been designated as desired channels, and if all possible storage space for storing desired channel identification has been utilized.  In addition, the dual use of a few pushbuttons is disclosed such that the sequence in which these pushbuttons are actu-ated determines the transceiver mode of operation selected.

Abstract: BUFFER CIRCUITRY            Abstract:         A buffer circuit comprising pull-up and pull-down switching devices gives a digital output signal in response to a digital input.  Signal waveforms are applied to the circuit to pre-bias the output terminal to the "1" potential level.  This permits the pull-up device to be of relatively high resistance, while the pull-down device is of low resistance.  The disclosed cycle of operation conserves power, and the use of a high-resistance pull-up device permits savings in semiconductor chip area.

Abstract: ABSTRACT           A beam-type transfer mechanism for moving work-pieces step by step along a row of stations through the dies of a press to progressively form a blank into a finished part.  A pair of laterally spaced beams extend parallel to the row of stations, having opposed work holding fixtures cooperable to grip the workpiece.  The beams are movable in operation laterally toward and away from each other, vertically up and down, and longitudinally,to simultaneously advance the workpieces one step at a time from station to station.  The dies would ordinarily be removable and replaceable through the front of the press except for one of the beams which occupies and obstructing position throughout its entire operative movement.  Means are provided to lift the beams sufficiently to enable the removal and replacement of the dies through the front of the press without obstruction.

Abstract: ABSTRACT OF THE DISCLOSURE A creepless, snap action thermostat is formed employing two movable contacts. One of the contacts is mounted to a bimetallic arm which moves as the temperature of the environment in which the thermostat is located in-creases. The second movable contact is mounted on a spring arm, the spring arm following the motion of the bimetallic arm upon increased heating, so as to maintain firm mating of the two contacts until the snap over point of the bimetal is reached. After snap over, the contact on the spring arm is prevented from following the contact on the bimetallic arm because of a physical stop formed in the thermostat casing.

Abstract: ABSTRACT           Adhesive is applied to a substrate for a printed circuit board in a pattern corresponding to that of the printed circuit.  If the adhesive is of the type which contains a solvent, the substrate and adhesive are heated after application of the latter in order to drive off the solvent.  Subsequently, a thin foil of a material which is capable of bonding to a chemically deposited metal is pressed onto the adhesive.  The adhesive is then permitted to set which causes those portions of the foil in contact with the adhesive to adhere tightly to the latter.  Once the adhesive has set, the foil is peeled from the adhesive.  The portions of the foil which contact the adhesive remain bound to the adhesive thereby forming a base which is capable of receiving a chemically deposited metal.  The thus-coated substrate is immersed in a bath where an electrically conductive metal for forming the printed circuit is chemically deposited in a pattern corresponding to that of the adhesive and, consequently, of the printed circuit.

Abstract: Abstract of the disclosure Certain reactive dyestuffs of commercial constitu-  . tion are available in a form which does not react with cellulose fibers and have therefore to be converted into their reactive form before being able to undergo a covalent bond with the fiber materials. The methods hitherto applied in the practice for this purpose are unsatisfactory because they either do not produce a suffi-cient amount of reactive dyestuff under the prevailing conditions, or due to susceptibility of the converted form to hydrolysis, portions of the dyestuff are in activated, thus resulting in dyestuff losses in both cases.        In accordance with the invention these drawbacks are overcome by converting first the dyestuffs   to their fiber-reactive form, before dyeing or printing, by treating them under correspondingly typical conditions, for example in an alkaline medium, and chemically stabilizing then this converted form by alteration of the pH, for example to the acidic range. The dyestuff formulations so obtained are then used for the dyeing or printing of cellulose fibers in a neutral to acidic pH range. This is the decisive condition for acceptable yields as compared to the hitherto known operation modes.

Abstract: ABSTRACT    An MOS semiconductor device comprises a semiconductor substrate and a gate electrode formed on a principal face of the substrate with an insulating oxide film therebetween.  A source region is formed in the substrate to one side of the gate electrode and a drain region is formed in the substrate at a location on the opposite side of the gate electrode to the source region.  A pair of pinch-off resistor regions in which pinch-off occurs, extend inwardly from the source region and the drain region, respectively, towards the gate electrode, and a channel extends between the source and drain regions.  The length of the channel between the drain region and the source region is greater than the width of the channel measured in a direction perpendicular to the channel length.  The source region and drain region are located in isolation from a channel stopper region surrounding the device.  The device is useful in an output buffer circuit for direct driving of a high breakdown load, such as a fluorescent indicator lamp, and the formation of the pinch-off regions in the above manner provides a large resistance for a small area.  Thus, the device is particularly suited to IC fabrication.

The end edges and side walls of the filling hopper halves are in sealing contact with each other when the filling hopper halves are in their swung-in-position.          As a result the cross-section of the opening defined by the spread-apart filling hopper matches the cross-section of the spread opening of the bag.  Because the filling hopper halves are in snug contact with the inside surface of the bag, no passages are left through which dust can escape.
