Patent number: 4125812Abstract: Apparatus for baseline restoration in an AC-coupled signal is comprised of a differentiation circuit followed by an integration circuit to receive the signal and continually restore its DC reference. Both circuits are initially set to the DC reference, and reset after a lapse of some predetermined period based upon the worst case signal-to-noise ratio anticipated for the system. Transmission is terminated, or interrupted, before resetting. A header may be used to signal resumption of transmission to the apparatus in an asynchronous receiving mode. In a synchronous receiving mode, the transmission is simply interrupted at each time the apparatus is reset.Type: GrantFiled: June 17, 1977Date of Patent: November 14, 1978Assignee: Bunker Ramo CorporationInventor: John D.

Patent number: 4121201Abstract: A simply installable, economical, room of a motel or hotel unit is provided in each room and an electrical device to be protected is connected to the room unit without the need for any modification of the device. The room unit is of sufficient sensitivity to sense various conditions indicative of an attempted theft, including the difficult to sense condition of cutting the power cord of the electrical device when the device is off. Each room unit is responsive to the detection of a condition indicating an attempted theft to produce a unique alarm signal which is coupled back to the AC power lines. The power supply lines of a plural phase AC power system customarily provided in the hotel or motel are used to transmit the alarm signals from the room units to receiving means for detection, and spare telephone lines which are customarily also available are used to transmit the detected alarm signals from the receivers to a central monitoring location.Type: GrantFiled: March 22, 1974Date of Patent: October 17, 1978Assignee: Bunker Ramo CorporationInventor: Paul Weathers

Patent number: 4102023Abstract: A contour shear rest is disclosed for use in a plane shearing machine to simulate, in a three dimensional deep-pile fabric, the effect obtained by sewing together small animal pelts such as mink. The shear rest has a contour surface made up of elements forming a mirror image of a desired contour. The contour surface is formed so that the length of the travel path of fabric drawn across its face is uniform. Tension applied to fabric drawn across the various surfaces is therefore uniform and fabric distortion is substantially eliminated. Subsequently, as the fabric is sheared, it is provided with desired natural-looking contours.Type: GrantFiled: August 30, 1976Date of Patent: July 25, 1978Assignee: Bunker Ramo CorporationInventor: Norman Christian Abler

Patent number: 4099022Abstract: A system for data pulse transmission through a single-wire, water-return cable payed out from a coil in an open pack to any selected length over a predetermined wide range (e.g., 4K to 16K feet) employing a toroidal core around the cable near the pack and a multiturn primary winding on the core. The single-wire cable constitutes a single turn secondary winding terminated at the receiver end by a resistor and coupled to the water (circuit ground) at the transmitting end by stray capacitance between the cable remaining in the pack and the surrounding water. The receiver employs an equalizing network to compensate for the amplitude-frequency characteristic of the cable of nominal length within the predetermined range resulting in only slight over-compensation for a shorter cable length and slight under-compensation for a longer cable length.Type: GrantFiled: January 5, 1977Date of Patent: July 4, 1978Assignee: Bunker Ramo CorporationInventors: Robert A. Fullerton, George V. Podraza

Patent number: 4098389Abstract: A platen control mechanism includes a cam member which urges a cam following platen into three positions during a printing cycle. Two separate solenoids are connected to the cam member for moving the member to three distinct positions. In a first position both solenoids are de-energized thereby causing the platen to assume a wide gap position with respect to a printer head. This permits the insertion of a document. In a second condition, both solenoids are energized thereby forcing the platen into pressing relationship with a printer head. A third condition exists when one solenoid is energized and the other is de-energized thereby causing the platen to assume a narrow gap position with respect to the printer head which allows indexing motion of the document. At the end of a printing operation, both solenoids are de-energized so that the platen may return to a wide gap position permitting removal of the document.Type: GrantFiled: August 20, 1976Date of Patent: July 4, 1978Assignee: Bunker Ramo CorporationInventor: Okun Kwan
