Abstract: A protective system to prevent a dry metallized film capacitor from rupturing its case or catching fire in the event that an internal short or fault occurs within the capacitor section utilizes a fuse and a thermal protector connected in series with the capacitor section and within its case. The fuse serves to protect the unit from a fault-induced low resistance high current in-rush, while the thermal protector is triggered by a fault-induced high resistance low current. A heat reflective circumferential sheet and the postioning of thermal protector maximize its value in the protective system.

Abstract: An electrical connector adapted to be mounted on a circuit board has at least two legs (2, 3). Each leg (2, 3) press-fits into a corresponding hole in the circuit board, and is shaped to possess a cross-section perpendicular to its longitudinal axis which is a closed geometric shape having a major axis substantially perpendicular to a minor axis. A diamond shape is a preferred design. The length of the major axis of each leg cross-section is greater than the diameter of the corresponding mounting hole in the circuit board and the length of the minor axis is somewhat less than the diameter of the corresponding mounting hole in the circuit board. A contact wire can be secured into the plastic body of the connector by melting a portion of the plastic in contact with the wire along a portion of its length with ultrasonic energy and then allowing the plastic to solidify.

Abstract: An angle modulator operated intermittently for the reduction of the power consumption of radio equipment, and so on, receives a frequency control voltage and an input modulating signal at different terminals of a variable capacitance diode (D) so that the frequency control voltage is applied directly to the variable capacitance diode without being affected by the coupling capacitor for the modulating signal. This allows a quick response to the frequency control signal and a rapid tuning after the start-up of the modulator.

Abstract: Sheet-feeding apparatus with a sheet support tray (10), a rear vacuum plenum chamber (19) adapted to acquire the rear portion of a sheet, a front vacuum plenum chamber (18) positioned over the front of the tray and adapted to acquire the front portion of a sheet, a sheet transport (27) associated with the front vacuum plenum to transport a sheet acquired in a forward direction, and an air knife (29) positioned at the rear of the stack of sheets to inject air between the trail edge of the top sheet in a stack and the remainder of the stack. The trail edge of a sheet in a stack is separated by the air knife, acquired by the rear vacuum plenum then acquired by the front vacuum plenum and transported in a forward direction. As the trailing edge clears the rear plenum, the rear plenum, which together with the air knife is continuously actuated, acquires the next sheet in the stack. In this way, the speed of the sheet feeder can be very high, since sheets are separated and acquired by the feeder simultaneously with transporting them off the stack. Preferably, the air knife includes preacquisition fluffer jets to loosen the top few sheets in the stack initially and lateral converging air streams to facilitate separation of the topmost sheet in the stack. The front vacuum plenum includes sheet acquisition tunnels over virtually its entire sheet contact surface in order to accommodate a wide variety of sheet sizes.

Abstract: The invention teaches a method of spacing the elements (20, 16) of a flame arrestor and securing that spacing in a simple and economical manner. A shim (12) is used to space the elements (20, 16), the elements (20, 16) are welded together and the shim (12) is removed. This leaves a controlled flow path between the elements (20, 16) but the spacing is such to prevent the propagation of a flame through the arrestor.

Abstract: The power supply circuit has a bridge rectifier (1) at its input connected to a primary winding (2) of a transformer (Tr). Connected to the other end of this winding is a switching transistor (T1) which is alternately blocked and rendered conductive by an oscillator (o). Voltage pulses from the transformer are passed to a rectifier (12) to obtain a control voltage (Ur) applied to an input connection (f) of the oscillator so that its operating frequency is lowered as the control voltage is reduced. This control voltage also controls the switching on time of the switching transistor, stabilising its operating voltage.
