Title: Record carrier with sector address  sections
Inventor: KLEUTERS WILHELM J
IPC: G11B20/18
Filed: 1979-03-12
Granted: 1983-05-24
Abstract: PHN.9062 12.5.78 ABSTRACT:               It is described how a user can optically record information in a round disc-shaped record carrier body, and can read the recorded information with one comparatively simple apparatus. The record carrier body which is used is provided with a servo track, which preferably exhibits a phase structure and which contains a multitude of sector addresses per revolution.          The apparatus employs only one radiation beam.          Before the information is recorded the desired address is Located first. Simultaneously, the radial position and the tangential speed of the radiation spot and the focussing of the radiation beam are checked. While the information is being recorded between the sector addresses it is possible to check whether this information is recorded correctly. During reading of the recorded information the servo track may be used for positioning the radiation spot on the information track.

Abstract: 15.2.79                    1                  PHO 78508 ABSTRACT: Reproducing  apparatus for a colour television signal recorded on a record carrier.          In a reproducing apparatus for a colour tele-vision signal recorded on a record carrier, of which at least the chrominance signal which contains the colour synchronizing signals is recorded with periodically changed polarity in the individual line period sectors in at least one of two adjacent tracks, the polarity of the reproduced signal in the individual line period sectors is  switched so by means of a polarity switching device that the polarity change effected during recording is cancelled, which enables cross-talk signals from an adjacent track to be suppressed. In order to ensure that the change in polarity during reproduction is always in synchronism with the change in polarity during recording, there is provided an identification circuit for the phase relationship between two such colour synchronizing sig-nals, which should be in phase in conformity with the television standard when the polarity change during re-production exactly cancels the polarity change effected during recording. Thus, in the case of an incorrect polarity during reproduction this identification circuit supplies a signal by means of which the switching state of the polarity switching device is each time changed by one switching steps until the polarity change during reproduction is again in synchronism with the polarity change during recording.

Abstract: A COMMUNICATING TYPEWRITER AND DICTATION SYSTEM UTILIZING ANALOG RECORDING AND TRANSMISSION TECHNIQUES                              Abstract A combined communicating typewriter/dictation system which utilizes a common modem as an interface between an elec-tronic typewriter, a mass media recorder and a communi-cations line.  The modem replaces digital logic and audio tones are recorded on the mass media recorder instead of digital tones.  When the system is in a local mode the digital keystroke signals from the typewriter are modulated by the modem and recorded by the mass media recorder.  In a communications mode the recorded keystroke signals are demodulated and then remodulated before trans-mission over the communications line to eliminate noise and other extraneous signals that tend to increase the error rate of the transmitted signals.  When data is received by the system for storage on the mass media re-corder,  the transmitted data is demodulated and then re-modulated by the modem to eliminate noise from the trans-mitted signal.  In both communication paths  the analog signal input to the modem is processed twice before it is either forwarded to the mass media recorder or to the communications line.  In addition to the foregoing re-cording functions, the mass media recorder can also be utilized to record and/or playback audio information. The dual utilization of the modem and the mass media recorder results in a low cost system without sacrificing much in the way of recording error rate.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention is directed to a two-component industrial maintenance coating system. The first component comprises a polyamine terminated epoxy resin which is end capped with specifically defined monoepoxides.  A co-solvent is optionally employed in the first component where the end capped adduct is a solid at room temperature.  The second component comprises a low molecular weight polyepoxide resin crosslinker and optionally a diluent when the epoxy crosslinker is very viscous or solid at room temperature.  Before the two components are mixed together the end capped adduct must be converted to its water soluble or water dispersable salt form by reaction with a volatile acid to achieve a certain degree of salting.          When the two components are mixed together the epoxide resin crosslinker is microemulsified.  The composition which results upon mixing the components is curable at room temperature and exhibits an excellent balance of chemical and physical properties.

Abstract: ABSTRACT        A prepared specialty frozen food product and method.  The product is a frozen pizza with a filling-receiving crust portion made from a bread dough and a filling portion received within the crust.  The method comprises preparing a bread dough product, subdividing the bread dough into individual dough elements, permit-ting the dough elements to rise, placing the dough elements within a forming pan having a flat, lower surface por-tion and an upwardly and outwardly tapering sidewall sur-face and pressing the dough elements within the pan so as to form the dough elements into flat sheets substantially co-extensive with the lower pan surface portion.  Next, the dough sheets are allowed to rise, and are re-pressed so as to further exclude the dough radially.  This causes the dough sheet to assume the contours of the pan bottom and sidewall and causes the crust to assume substantially uniform thickness in the bottom and sidewall areas of the pan.  Then, the crust is at least partially baked, is removed from the pan and placed in a container other than the forming pan.  Finally, the crust is filled and frozen.

Abstract: DUAL THERMOSTAT CONTROL APPARATUS                  WITH DEAD BAND RESPONSE              Abstract OF The Invention A dual thermostat apparatus includes two thermostats which generate fluid control signals pro-portional to room air temperature.  The thermostats are matched leakport pressure sensors having a signal orifice and a bimetal lid element to generate back pressure signals linearly related to temperature.  The bimetal elements have adjustment cams to set the reference position with respect to the orifice.  The cams are connected to a common shaft and dial to provide simultaneous and opposite readjustment with respect to the reference pressures.  The signals are applied to separate signal chambers of the duplex relay, with a pressure regulator connected to the heat signal chamber to limit the operative pressure level of the heating signal to a selected maximum switchover pressure,  The duplex relay controls a pressure supply valve for supplying a proportional pressure signal to a common output line to pneumatic operators of a heating valve and a cooling valve.  The regulator and duplex relay create a control in which the heat pressure signal operates to one side of said reference pressure and the cooling signal controls to the opposite side of such reference pressure.  The position of the cams sets the required temperature related movement before the operative back-pressure signal is established and thus defines a dead band region in which neither heating or cooling is provided. The signal switchover becomes operative only in accordance with the dead band setting and thus a range in which neither the heating valve or cooling is actuated to conserve energy.                          -?-
