Abstract: 21.6.1978 ABSTRACT:          A magnetic tape transport system with a magnetic tape cassette is provided with a tape transport measuring device which comprises a rotary pulse device which cooperates with a light source and a light-sensitive cell, the pulse device being rotated during transport of the magnetic tape and the number of pulses detected by the photo-cell being counted and displayed with the aid of a read-out device, such as a digital display device. In order to obtain a correct linear relationship between the length of tape which has been transported and the number of counted pulses, a tape guide roller in the cassette is used as pulse device, the cassette housing locally being provided wiht a light-transmitting portion, such as openings or transparent por-tions.

Abstract: ABSTRACT OF THE DISCLOSURE         A detachable sunroof panel is adapted to be secured within an opening formed in the roof of an automobile.  The securement is carried out by a system of latches, all of which act on the panel to compress a resilient seal member extending about the periphery of the opening between the roof panel and a lip portion formed on a frame secured within the opening. The latch system includes a latch-handle mechanism located at the rear edge of the panel comprised of an overcenter linkage which may also be detached for removal of the sunroof panel. The latch-handle may be moved to a latched position, or to a second vent position allowing movement of the rear portion of the sunroof panel upwardly to create a vent opening.  The latch system further includes a pair of latch-hinges located along the front edge of the panel, each of which also comprise a releasable overcenter linkage adapted to compress the peri-pheral seal in the secured or locked position and upon release allow detachment and removal of the sunroof panel.  The hing-ing action required in the vent position of the panel is created while the latch-hinges are in the locked position by deflection of the frame lip and latch-hinges such that a biasing closing force is imposed on the sunroof panel in the vent position to tightly position the panel preventing rattle or loosening of the components.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus is disclosed for storing heat.  Liquid heat storage medium is disposed within a reservoir and a crystallization drum is partially immersed in the medium.  A secondary heat carrier liquid flows in controlled fashion through the drum to a heat containing device.  Thus, the secondary heat carrier withdraws heat from the storage medium in the vicinity of the exterior of the drum.  As a consequence, the cooled portion of the storage medium solidifies on the walls of the drum and, as the drum is rotated, the solidified medium is brought back into heat exchange relationship with a primary carrier liquid.  The invention thus accomplishes the heat storage by way of crystallization or fusion heat.

Abstract: C-3071                                          D-2,847 Abstract of the Disclosure A common gate field effect transistor amplifier has a source bias resistor effective to establish source bias voltage near pinch-off.  A current source is connected through a diode having a dynamic RF impedance which varies inversely with direct current therethrough to the source of the field effect transistor.  An increase in current from the current source in response to a change in an automatic gain control voltage causes increased current flow through the diode and conse-quently through the bias resistor to increase source voltage and thus reduce amplifier gain.  The same increase of current through the diode reduces its dynamic RF signal impedance and allows shunt of RF signal therethrough and through a shunting capacitor to ground to further decrease gain of the amplifier and improve its overload characteristics.

Abstract: ABSTRACT "Arrangement for testing a device provided with an echo canceller"         The test arrangement is intended to test, for example, a modem whose transmitter and receiver are coupled to the transmission line by means of a hybrid junction and comprises an echo canceller. The test consists of comparing a test signal applied to the transmitter with the signal restituted by the receiver when the modem is fedback from the line side. The test arrangement comprises an adder one input of which receives the error signal coming from the echo canceller, the other input receiving, during the test the feedback signal, its output being connected to the re-ceiver. Means have been provided to make the signal resti-tuted by the receiver different from the test sequence, when the error signal of the echo canceller passes a threshold.

Abstract: Abstract of the Disclosure Method and apparatus for controlling the food cooking time in a microprocessor controlled microwave oven in response to the remotely sensed condition of the food being heated.  The average food temperature is constantly derived during cooking, utilizing user entered data on the food category, the food's initial mass, and the measured input power to the magnetron.  The average current and average peak voltage input to the magnetron are sensed and the ab-sorbed power in the food is derived using the magnetron efficiency.  A self-calibrating analog to digital converter provides the magnetron input power in digital form for a microprocessor controller.  In one embodiment the  micropro-cessor sequentially derives the average food temperature as a function of cooking time using the entered food data, stored cooking coefficients previously determined by regres-sion analysis, and the measured magnetron input power. In the preferred embodiment the microprocessor derives the cooking time as a function of the average food temperature using the entered food data, a stored constant previously determined by regression analysis, and the measured magnetron input power.  In either embodiment means are provided so that the user may select the final food temperature within the range from "rare" to "well done" and cooking continues until the desired final temperature is reached.
