Abstract: A folder apparatus is disclosed which has a removable mounting plate supporting both of the corresponding exit rollers of a single lead-in tape assembly. The modular cartridge formed by the mounting plate and exit rollers allows for easy replacement of these parts in the folder.

Abstract: A folder apparatus is disclosed which has at least one lead-in tape mechanism having a left lead-in tape and left exit roller and a corresponding right lead-in tape and right exit roller, the fight and left lead-in tapes forming a signature passage for delivery of a stream of signatures. One of the exit rollers is spring-loaded in the direction of a fixed exit roller. The spring loading takes place with two springs acting opposite one another, the springs having different spring rates or modula. This dual spring action reduces pounding caused by the signatures as they pass through the lead-in tapes.

Abstract: A folder apparatus is disclosed which has at least two side-by-side lead-in tape mechanisms having a left lead-in tape and left exit roller and a corresponding right lead-in tape and right exit roller, the right and left lead-in tapes forming a signature passage for delivery of a signature, and the left exit rollers being at a different height than the right exit rollers. The rollers of the side-by-side tape mechanisms have alternating heights. The exit rollers may be fixed or spring-loaded in the direction of the corresponding roller.

Abstract: Several unique features for an improved espresso/cappuccino maker are disclosed. A method and apparatus for replenishing the steam tank for a cappuccino steam dispenser in which the cold replenishing water can only be added in stepped sequences, and only after the water in the tank has reached its desired operating temperature. The dispensing unit for holding the coffee filter is maintained in a constantly heated condition by direct thermal conductivity from the metal surface of the hot water tank which is nested and in direct contact with the metal of the dispensing assembly. The temperature probe for the steam wand is housed internally of the steam wand with only a tip protruding for ease of cleaning. Also, the entire steam wand assembly and solenoid control valve are pivotally mounted as a unit to eliminate the need for internal slip joints in the steam lines. A portafilter has an integral screen for holding a single, a double, or a double-double portion of ground coffee.

Abstract: A method for deoiling oil residues from surfaces of inorganic particles each having pigment in an outer layer thereon, comprising contacting the surfaces with a deoiling solution comprising a mixture of monocyclic terpene and aliphatic petroleum distillates in an amount and manner effective to wet substantially all the surfaces of the inorganic particles, whereby the deoiling solution removes substantially all the oil residues from the surfaces of the inorganic particles.

Abstract: A method for the continuous formation of a stack of folded products standing on edge includes feeding folded products to a stack of folded products standing on edge. The stack is moved forward with a conveyor belt at a speed being matched to the feeding of the folded products to the stack. An interruption in the continuous feeding of the folded products to the stack is detected. A separating device is activated. The conveyor belt is stopped for the duration of the interruption. A device for the continuous formation of the stack of folded products includes a device for feeding the folded products in a stream to a stack of folded products standing on edge. The stack is moved forward on a conveyor belt at a speed being synchronized with the feeding of the folded products to the stack. At least one separating device contacts the folded products. A sensor monitors the stream of folded products and supplies output signals.

Abstract: Continuous combustion heat engine including a compressor (12), combustor (14) and expander (16) which operates on a Brayton cycle with positive displacement pistons (90) in the compressor and variable expansion ratio pistons (190) in the expander. Compressor (12) delivers compressed air to the combustor (14) where it is mixed with fuel and combusted to produce expansion gases for the expander (16). Power input to the compressor and power output from the expander are achieved through the radially disposed pistons (90,190), connecting rods (94), cranks (98), crank shafts (100), planetary gears (104), sun gears (106) and sun gear connectors (114) which rotatably secure the sun gears (106) and manifolds (110,166) together. The pistons (190) for the expander have positive displacement sections (192) and free floating sections (200) for the variable volume ratio capability.

Abstract: Rotary engine having a hollow, stationary block with manifolds for air inlet and exhaust valving and means for supplying fuel. The block supports one or more in-line cylinders which are provided with opposed pistons equipped with rigid and constrained piston rods. The rods carry bearings that run along a cam track surface interior to a disc, the outer surface of which is a right circular cylinder. The surrounding right circular cylinder rotates as a result of the linear movement of the opposed pistons thereby providing mechanical power. The cam surface is a continuous track which determines the out-put motion of the piston movement between top and bottom dead center. Arcuate areas at top and/or bottom dead center permit constant volume combustion and/or exhaust as desired during a particular cycle, whether that cycle be Otto or Diesel and whether it be two or four stroke.

Abstract: A snow-removal device includes a frame having a handle at one end and a blade at the other. The frame rests on the ground at the blade end, and a flexible sheet extends from the blade end back toward the handle end. The sheet is attached at either end but is free to bend lengthwise so that the length of the sheet resting on the ground varies as the handle is lifted. This arrangement permits the device to be emptied with a minimum of strain on the user.

Abstract: Diesel fuel injection system in which a standing high-pressure wave is maintained in the common rail and which utilizes injectors which function as gates or valves. Electronic controls sensitive to engine demands based on speed and load electronically control the injectors to vary both moment and duration of fuel injection time. Input signals, as determined by engine speed by way of the distributor, vary the injection timing according to an advance curve at the distributor correlated to piston position. Duration of the injection cycle (quantity of fuel injected) is controlled electronically and variably in relation to throttle position.

Abstract: A phonograph cartridge replaceable stylus assembly is provided. The assembly comprises a housing having a nonmagnetic tube affixed thereto. The tube has a forward end and a rear end extending outwardly away from the housing. A nonmagnetic stylus arm extends through the tube forward end. A jeweled stylus is mounted to the front of the arm. The rear end of the arm passes through an elastomeric damper positioned within the tube. The damper serves as a universal pivot joint for the arm. The damper comprises a cylindrical member having a forward edge and a rear edge. The tube is crimped along a circular crimp line engaging the damper intermediate the forward and rear edges with the portions of the damper that do not engage the crimp also being free of the tube. A magnetic member is positioned within the tube secured to the arm and adapted to move therewith in response to motion of the jeweled stylus and following the grooves of a record.

Abstract: Alarm system in which the latch plate of the door jamb is movable to contact a striker plate spaced and insulated therefrom to close an alarm circuit. The system is so designed that if an attempt is made to force the lock, the latch plate which is resiliently mounted will move and thus make contact with the striker plate. A contact relay and thermal relay are incorporated in the alarm system in such a way that the alarm can be timed to signal for a predetermined length of time after which it will automatically shut off. As soon as the alarm signal has stopped the system is ready to signal again.
