Abstract: When a large diameter disc is inserted into the disc drive, diameter sensing probes detect the large diameter and unlock movable disc guides and subsequently induce the guides to separate to levels wherein passage of the large diameter disc is faciliated. The guides are locked in a manner which prevents the same from returing to the positions suited for guiding small diameter discs until such time as the large diameter disc is unloaded from the device. 
     Lever means mounted in the drive respond to the diameter of the disc loaded and assume configurations relative to the diameter of the loaded disc. The lever means is locked in a configuration suited for small discs until such time as a large disc is introduced. At this time the lever means is unlocked. The means includes means which sense the periperal edge of the disc and hold the arrangement in a configuration suited for the larger diameter.

Abstract: Method and apparatus for controlling the output emissions of a gas turbine engine. In an emissions combustor (5) the gas is burned locally (8) and then thoroughly mixed (6) with cooler unburned portions while the resulting very hot flame front is propagated over the whole gas stream flow. The emissions combustor serves to reduce the carbon monoxide content of the output. NOX can be eliminated by steam injection into the engine main combustor in combination with the emissions combustor. Combustion efficiency, which is reduced through the steam injection in the main combustor is recovered through the use of the emissions combustor. The emissions combustor can be placed at numerous locations, either as part of a main combustor staging, downstream of a high pressure turbine, or in a supplementary burner after a power turbine.

Abstract: A multi-channel stereophonic system in which different audio signals are produced and caused to converge upon a listening site in an enclosure at selectively spaced time intervals so as to enhance the realism of the sound impressed upon the listener. A first pair of auxiliary speakers are arranged in front of and above a pair of conventional main speakers with one of the auxiliary speakers facing the ceiling of the enclosure. Signals are transmitted from an amplifier in selected phase relationship to each of the auxiliary speakers, the sound produced at least by each of the first pair of auxiliary speakers being selectively reflected off of sound-reflective surfaces in order to physically separate the added sound produced by the auxiliary speakers from the conventional stereo speakers. One of the speakers of the first pair of auxiliary speakers is connected out-of-phase to the amplifier while the other speaker is connected in phase. A second pair of auxiliary speakers are arranged behind the ideal listening site facing a rear wall of the enclosure. One of the speakers of the second auxiliary pair is connected out-of-phase to the amplifier while the other speaker of the second auxiliary pair is connected in phase.

Abstract: The invention relates to a method for detecting rapid damping changes in the oscillator input circuit of a proximity switch. A high-frequency oscillation gener­ated by the oscillator and amplitude-modulated by the damping changes is demodulated such that a demodulated signal voltage which fluctuates with the frequency of the damping changes is obtained. This signal voltage is amplified as ac voltage and the amplified signal vol­tage is converted by means of threshold switching de­vices to a pulse sequence with a pulse sequence fre­quency which corresponds to the frequency of the vol­tage changes in the signal voltage.

Abstract: A picture processing device in which picture data of a road or lines marking off a lane taken by a television camera installed on a vehicle is processed for the recognition of the configuration of the road or the lane. Picture data is analog/digital converted (15), then edited and is subjected to the binary processing (17) to be supplied to a DDA computing circuit (18). The DDA circuit comprises circuits serially connected each of which computes a rotary motion recurrence formula every rotation by a rotation angle. The recurrence formula is computed in a pipe-line system. In this computation a Hough transform is performed to give sine curves in a ρ-ϑ coordinate system. The points of intersection of these sine curves (Hough curves) are given, and those of them having more occurrences are selected in the ρ-ϑ coordinate system. As a result, the shape of the shoulder lines and the center line of the road, or the configuration of the lane are given.

Abstract: More efficient encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique prediction arrangement. The prediction arrangement determines whether high resolution pixels to be recomposed from low resolution pixels from a low resolution replica of the high resolution are so-called typically predictable or non-typically predictable by using general prediction rules. The general prediction rules are also employed to determine if any of the typically predictable high resolution pixels would be improperly recomposed. Such high resolution pixels which would be improperly recomposed are identified as exceptions. If is noted that so-called supplemental information is required to properly recompose non-typically predictable pixels and typically predictable pixels which are identified as exceptions. To this end, exceptions accompany the low resolution pixel for which the corresponding high resolution pixels would otherwise be improperly recomposed.

Abstract: A high pressure sodium arc tube assembly includes a light-transmitting arc tube (10) containing a fill material including sodium and mercury, a pair of electrodes (14,16) sealed in opposite ends of the arc tube, and a filament (24) or other resistive member located within the arc tube and extending between opposite ends thereof. The filament (24) is electrically connected to the electrodes (14,16). The filament (24) provides a sufficient electric field and an abundance of electrons dispersed throughout the discharge region to initiate an arc discharge when the electrodes (14,16) are ener­gized. The filament is selected to produce an electric field in the discharge region prior to initiation of arc discharge of at least 20 volts per centimeter. After an arc discharge is initiated, the voltage between the electrodes (14,16) drops, and the filament (24) is part­ially short-circuited by the arc discharge. The filament provides fast initial starting and fast hot restarting, while eliminating the requirement for high voltage start­ing pulses.

Abstract: An agricultural baling machine controls the density of bales of crop material discharged therefrom by monitoring the stress experienced by a reciprocably driven plunger assembly (22) employed to apply a compactive force to crop material introduced into a bale case (20). The bale case (20) is comprised of rails (54, 56) which are positionably adjustable in response to applied tension in a manner whereby the dimensions of the bale case (20) are changeable, thereby facilitating a change in the degree of resistance caused by the bale case (20) to crop material movement therein. Signals produced by stress sensors (124, 126, 128, 130) mounted relative to the plunger assembly (22) are analysed by a programmed signal processor (200) which accordingly generates a control signal for controlling a servo valve (61). In response to the control signal the servo valve (61) governs the degree of tension applied to the bale case rails (54, 56) and thereby adjusts the degree of resistance to crop movement in the bale case (20). The analysis performed by the signal processor (200) results in the generation of a pulse width modulated control signal that enables the servo valve (61) to adjust the degree of resistance to crop movement in the bale case (20) so that the stress experienced by the plunger assembly (22) is maintained near a predetermined level in accordance with desired bale density.

Abstract: In typing and printing mechanisms DC motors are often also used today, their driveshafts being provided with timing discs which via a sensing device provide for every step carried out a pulse for a control device with a counter. In this process, it may occur that the DC motor with the timing disc vibrates backwards and forwards after a step process in such a way that the counter is loaded with a plurality of counting pulses. These incorrect counts are avoided according to the invention by providing a control element which keeps the signal supplied to the counter (11) at an active level longer than the clock signal which triggers this signal and is generated by the timing disc (3). As a result, the mechanical range for vibrations is increased without counting errors occurring. <IMAGE>
