Patent number: 4403112Abstract: An audio speaker system is disclosed providing improved fidelity of performance from overdamped woofer drivers in small sealed enclosures. At least two woofer drivers are employed, and are driven electrically in such a manner that the phase difference in the electrical signals to the two drivers, or sets of drivers if more than two are employed, will be near zero at the lowest bass frequency and will increase to a value up to 180 degrees at the highest bass frequency which is generally taken as the woofer-midrange crossover frequency. This aforementioned phase difference in the electrical signal inputs to two sets of woofers common to one sealed enclosure improves over prior art by providing increased low-bass acoustic output, less acoustic wave interference between the woofers and the midrange drivers, and a smoother input impedance characteristic in the bass frequency region.Type: GrantFiled: May 18, 1981Date of Patent: September 6, 1983Assignee: Modafferi Acoustical Systems, Ltd.Inventor: Richard Modafferi

Patent number: 4396315Abstract: A precision high velocity cutting tool having indexable inserts or cutting bits includes a replaceable cutting section or insert holding nest that is made of a material that is harder and stronger than that from which it is economical to make the major cutter body. The nest is easily replaced without removing the cutter body from the drive shaft or spindle. Two holding screws retain the nest on the cutter body, one of them also securing an indexable cutter insert in cooperation with a reversible clamp. The nest facilitates the replacement of that portion of the cutter body that tends to deteriorate most rapidly and enables the replacement to be confined to the damaged area of the tool. A shaver blade is included that effects, in cooperation with the main cutting inserts of the cutting tool, smoother cutting, providing a finish approximately a planed surface.Type: GrantFiled: May 7, 1981Date of Patent: August 2, 1983Inventor: Burton E.

Patent number: 4310107Abstract: A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has an internal chamber and a flexible, elastomeric diaphragm-like cover on at least one side of the chamber in a component retaining body. Associated inlet and outlet valves, which valves may be discrete or integral with the diaphragm and body, and conduits are included whereby liquid from a supply thereof in the container is drawn up into the chamber when the diaphragm is flexed under stress. The diaphragm is operatively associated with a trigger device, the actuation of which flexes and stresses the diaphragm in a direction to decrease the chamber volume. Liquid which is present in the chamber is displaced and pressurized in a pumping action, forcing the outlet or discharge valve to open and the inlet valve to close allowing the liquid to flow into the outlet or discharge conduit and be dispensed from the device.Type: GrantFiled: February 28, 1980Date of Patent: January 12, 1982Assignee: The AFA CorporationInventor: Walter H.
