Abstract: A b s t r a c t:              The invention relates to a relay starter for a discharge lamp wherein that lamp is stabilized by a series arrangement of at least an induction and a capaci-tance. Also included in series with these stabilization elements and the lamp is an energizing winding of a relay a normally-closed contact of which is disposed in a cir-cuit which shunts the lamp.              In accordance with the invention a diode is also disposed in the circuit which shunts the lamp.          This achieves that if the lamp does not ignite, current flows for a short period of time through the diode which charges the capacitor. When this capacitor has received a sufficient charge no current flows either in the lamp circuit or in the shunting circuit so that the entire circuit is put out of operation.

Abstract: ARRANGEMENT FOR TRANSPORTING A MAGAZINE                  THROUGH A SETTING DEVICE     ABSTRACT OF THE DISCLOSURE     In a setting device, a magazine is advanced through a guide channel to present fastening elements in the path of a driving member.  The magazine is moved in a step-wise manner by a transport pawl, and the pawl, in turn, is reciprocated relative to the drive channel by an operating member.  A linkage inter-connecting the operating member and the transport pawl, includes a pin secured to the operating member extending into a triangularly shaped recess in the transport pawl. The pin pivots the transport pawl out of engagement with the magazine in the guide channel and moves the pawl rearwardly so that it can again engage the magazine and move it so that another fastening element is aligned with the driving member.

Abstract: CLOCK PULSE GENERATOR WITH SELECTIVE PULSE DELAY AND PULSE WIDTH CONTROL Clock generating apparatus for a computer system has selective pulse delay and pulse width control.  Selection of pulse delay and pulse width is accomplished by loading registers with predetermined data patterns.  The registers can be loaded under program control or by data entry units, such as a keyboard, switches, etc.  The registers are located in coarse land fine pulse delay and pulse width adjustment units.  These units have the same physical structure, but are functionally definable by a settable control element.  A dither delay element is included in these coarse and fine adjustment units, and it is selectable to provide a small increment of delay. The coarse pulse delay and pulse width adjustment units also include pulse mode control circuitry to control operation in either normal oscillator mode or in single cycle mode.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an electronic detection and transmission system known in the art as a money clip.  Presently available such money clips are pressure sensitive and transmit initiating signals on detection of a decrease in pressure.  Such systems have disadvantages, and the present system overcomes certain of the disadvantages by providing a system wherein det-ection is accomplished by a light sensitive means such as a photo-transistor.  In accordance with the invention, the electronic circuitry is contained in a housing having a top surface.  The phototransistor is disposed below an opening in the top surface, which is preferably centered on the top surface.  When the opening is uncovered, light will enter the opening and fall on the photo-transistor to activate the phototransistor.  The phototransistor is connected in circuit with a transmitter which will similarly be activated to transmit an initiating signal.

Abstract: ABSTRACT       The invention provides a circuit with a field-effect transistor device which can be used in controlling power transfers between an alterna-ting polarity power supply and a load, with the supply and load, in opera-tion, connected on either side of the device channel.  In one form, there is effectively provided a bypass connected on either side of the device channel and to the substrate of the device.  In another form, such bypass can be connected between the substrate or either end of the device channel and the gate region.  Both of these forms can be combined for use with one such field-effect transistor device.  Either or both of these forms, used with such a field-effect transistor device, can also be used in circuits in which the only power supply present is the alternating polarity power supply for providing power both to the load and to other circuit components which operate with constant polarity electrical power.
