Abstract: ABSTRACT:          For a d.c.-a.c. converter a control circuit is proposed which improves the efficiency of the con-verter and enables it to operate at a higher frequency using the same semiconductor switches. For this pur-pose the residual voltage across the currently conduc-tive switch is compared with a reference voltage via an analog OR-gate and the control signal for the conduc-tive switch is controlled in such a way that the residual voltage is set to a desired value.  The conver-ter with the control circuit is extremely suitable for use as a high-efficiency power-supply for fluorescent lamps and occupies the smallest possible volume.

Abstract: CHARGE REDISTRIBUTION MU-LAW PCM DECODER          Abstract of Disclosure A mu-law PCM decoder requiring a total capacitance of only 32 times the normalized capacitance Co of the smallest capacitor thereof.  The decoder comprises a source of positive and negative reference voltages, a differential input operational amplifier having its non-inverting input connected to ground, a storage capacitor CO=16Co connected as a feedback capacitor between the inverting input and the output terminals of the amplifier so that they operate as a voltage source, binary weighted capacitors Cl=Co, C2-2Co, C3=4Co and C4=8Co, and a second unit weighted capacitor C5=Co.  Switch means alternately connect one and other sides of C1-C5 (1) between ground and either a + reference voltage or ground, in accordance with the characterizations in a PCM coded digital input word, and (2? across the storage capacitor CO for redistributing charge on the capacitors for each segment of the designated polarity.  The resultant analog signal established on CO in the eighth segment is sampled prior to resetting the charge voltage on CO to substantially zero volts and receipt of the next PCM input word.  Connections of plates of integrated capacitors and electrodes of switching transistors to ground and terminals of voltage sources renders the decoder substantially insensitive to stray and parasitic capacitance effects associated with the integrated capacitors and switches.

Abstract: Abstract A vehicle for the temporary storage of refuse has a collecting sec-tion (12) which includes a basically vertical plate (20) which is moved in the longitudinal axis of the vehicle by a drive unit (21).          The plate regulates the size of the storage space of the collecting section, so that during the feeding in of refuse, the feeding unit, located at the extreme rear of the vehicle, achieves the necessary compression of the refuse.            According to the invention, the frame of the vehicle is formed by the bottom part of the collecting section.  Guiding and sliding units (35 a,b) for the plate and a number of strengthening elements are also arranged in the collecting section.  The strengthening sections assure the necessary mechanical stability in the bottom part and in planes through the guiding and sliding units. The guiding and sliding units preferably also serve as strengthening elements.  In a pre-ferred design, the bottom part is built up of a lower base plate (31) and two upper base plates (32 a,b) joined by basically vertical wall sections (33 a,b), so that the cross-section through the bottom part is like that of a channel.

Abstract: ABSTRACT OF THE DISCLOSURE An electro-mechanical direct drive valve servo system for an aircraft including a drive mechanism that couples the rotary output motion of a rotary force motor to linear motion at a sliding-type valve. The drive mechanism includes a pair of axially spaced rotary members connected to the force motor and a wobble member journaled between and canted by the rotary members with axial thrust bearings interposed between axially aligned opposed planar faces of the rotary and wobble members, A radial output arm on the wobble member is connected to the valve and is constrained for arcuate mutating movement whereby controlled rotation of the rotary member effects mutating movement of the wobble member and output arm which movement effects controlled linear movement of the valve. Additional control inputs such as bracing and recentering function inputs are accommodated by the drive mechanism at its input end to take advantage of the mechanism's inherent gearing force ratio.

In one embodiment of the present invention, each latching mechanism (of which there are two in the preferred embodiment) comprises but two separate components.  Each latching mechanism comprises one camming member and one buckling column spring.  The springs bias the camming members in a first position such that a portion of the camming member protrudes into the path the cartridge will travel as it is inserted into the tape machine.   When the cartridge is inserted, the leading edge of the cartridge engages that portion of the camming member.  The camming member is pivoted and moves to a second position;  the camming member comes to rest in its second position, in engagement with the notch provided as a standard feature on the bottom edge of the cartridge. Removal of the cartridge is accomplished by manually pulling the cartridge out of the tape machine.

Abstract: METHOD AND APPARATUS FOR AUTHENTICATING               MEMORY DISK                      ABSTRACT A technique for enabling authentication of a magnetic memory disk.  Predetermined portions of preselected tracks on the disk recording surface are deliberately removed and the locations of the modified portions are recorded, along with an initial program routine.  The portions are alternatively removed by mechanically abrading the recording surface using a stylus, by embossing the preselected portions and applying an abrasive member to the embossed raised surfaces, by burning off the portions with a laser, or by chemical etching.  When the disk is inserted into a drive, an initial program routine recorded on the disk causes the drive transducer to seek the pretreated portions and attempt a write and subsequent read operation.  A successful write/read operation indicates a counterfeit copy.  This indication may be used to signal the operator or erase the entire program from the disk.
