Abstract: ABSTRACT A radio paging receiver has a low voltage battery which permanently powers an oscillator and a higher voltage source, which make a DC-DC converter supplied by the battery, which powers a decoder portion of the receiver only when a power switch is closed.  At that time the higher voltage source is also supplied to the oscillator and the battery supply is effectively cut off.  The novel circuit permits the receiver to be started immediately by turning on the power switch and sounding an alert at its normal frequency while consuming very little power in its oscillator circuit.

Abstract: ABSTRACT     An automatic coin wrapping machine has a coin dis-penser which forms coins into a single file and moves them along a track past a counting star wheel to a downwardly curved discharged chute.  Coins leaving the discharge chute enter a stacking tube where they are formed into a stack.          The bottom of the tube is closed by a movable gate which is vibrated to assist stacking.  The formation of a proper stack is sensed by an optical sensor that checks the height of the stack.  When a proper stack is formed, the gate is removed and the stack of coins is lowered on a rod to a wrapping section in which three wrapping rollers engage a web of paper and wrap the paper about the stack.  Crimping hooks fold over the extending ends of the wrapper and the completed roll is discharged.  The width of the track and discharge chute are adjustable for different denominations of coins.  One side of the adjustable track and chute is formed on a plate which is pivotally mounted at the rear of the frame of the machine.          The other side of the track and chute is formed on a plate which slides over the first plate and moves parallel to it.     Adjustment is accomplished relative to a side frame so that the center of the discharge chute is always at the center of the stacking tube.  If the stack sensor determines that an improper stack has been formed, the stacking tube is moved laterally and is opened to empty its contents into a reject chute.

Title: Source of electrical energy for a resistance-welding machine
Inventor: BELAMARIC ZELIMIR
IPC: B23K11/24
Filed: 1982-05-12
Granted: 1985-03-05
Abstract: ABSTRACT          An electrical power source for resistance welding apparatus is described.  It is conventional in such a power source to use a static inverter and a welding transformer and to incorporate a static frequency converter, usually solid state, which derives an output voltage having a frequency and pulse shape different from the voltage fed to the inverter.  According to the invention, one or more parallel additional frequency converters are provided.  The output voltages of all the frequency converters are added in phase synchronism in the primary circuit of the welding transformer.  The use of at least two frequency converters permits very steep sided pulses to be obtained thus ensuring accurate weld beginnings and ends.  The shape, amplitude and work to space ratio of the pulses can be varied within wide limits.

The frame has a slidably, rotatable tubular member movable towards and away from the forward transverse member and the tubualr member has a pair of opposed planar faces joined by a pair of opposed curved faces, said faces providing a pair of opposed, relatively sharp edges. When the other end of the belt is passed through the frame by looping around the tube, then under the forward transverse  member, and after engagement with the outside of the belt, the motion causes the tube to move towards the forward transverse member and also rotate so that the sharp edges engage the belt, one to press it against the forward transverse member and the other to press it where it loops around the tube, thus providing positive engagement
