Abstract: ABSTRACT OF THE DISCLOSURE         An automotive vehicle wheel cover has a hub cover and a wire basket with decorative, interconnected wire spokes.  The hub cover is constructed with a central opening to receive a removable plate.  The plate is equipped with a threaded nipple which will receive a threaded stud on a hubcap so that the hubcap can be used to secure a retention ring against the wire basket to secure the hub-cap, the retention ring and the wire basket relative to the hub cover and to a vehicle wheel having a bolt on flange and a tire rim.  The wheel cover system may also be converted to accommodate a locking hubcap arrangement.          When the wheel cover is utilized in this manner the plate and hubcap are removed and a hub spacer is secured to the vehicle wheel against the bolt-on flange with lug bolts or nuts.  A replacement hubcap with a central axial recess is substituted for the original non-locking hubcap and a specially configured locking bolt is seated in the central recess of the hubcap and threadably engaged with the hub spacer by means of a special key. A decorative masking cap is mounted upon the hubcap over the locking bolt to conceal the recess and locking bolt from view.  The length of the hub spacer and the position of a fastener on the hub spacer are adjustable.

Abstract: INVENTOR:  KLAUS MUNZEL            INVENTION: IMPACT FUZE WITH FLIGHT TIME-DEPENDENT DETONATION            DELAY                    ABSTRACT OF THE DISCLOSURE                An impact fuze with a time-delay between the impact of a flying object, such as a rocket or projectile at the target and the detonation thereof renders possible the penetration of the rocket or projectile into the target before the detonation.  The flight velocity or speed of a projectile decreases with increasing flying time.  In order to ensure for a penetration depth which nevertheless is sufficient, the impact time-delay must increase with decreasing flight velocity of the rocket or projectile.  For this purpose, a time-delay counter is set by means of a self-destruction counter as a function of the flight velocity.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of attaching bottom stops of a generally H-shaped cross section to a slide fastener chain.  One of successive spaced pairs of opposed blank tape portions of the fastener chain is spread apart.  A bottom stop, which has two pairs of gripping legs, is placed between the spread pair of opposed blank tape portions.  The spread pair of opposed blank tape portions is then released and thereby allowed to come toward each other until a pair of opposed blank beaded tape edges are threaded one through a space between each pair of the gripping legs of the bottom stop.  Then, the blank beaded tape edges are compressed against the bottom stop on opposite sides.  Finally, the gripping legs of each pair are clinched about the compressed beaded edge of a respective one of the stringer tapes.  An apparatus for carrying this method is also disclosed.

Abstract: CONTROL CIRCUIT FOR RESETTING DRAWOUT                CIRCUIT BREAKER UVR SOLENOID                 ABSTRACT OF THE DISCLOSURE         A control circuit utilizes a system voltage monitoring control relay for applying a DC control voltage across a UVR solenoid and a voltage dropping resistor to maintain the UVR in its reset condition in the absence of an under-voltage condition.  An RC network maintains the UVR reset condition for momentary dips in the system voltage.  If the UVR does drop out to trip its circuit breaker, a second relay temporarily switches out the dropping resistor to render the control voltage capable of electromagnetically resetting the UVR.  To accommodate drawout breaker applications, means is provided to sense when the UVR is reconnected to the control circuit pursuant to automatically initiating a UVR reset function via the second relay.

Abstract: A B S T R A C T       PROCESS FOR REDUCING THE TOTAL SULPHUR CONTENT     In the process for reducing the total sulphur content of a high CO2-content feed gas stream, the feed gas is first passed to a column for the selective absorption of H2S. The unabsorbed, high CO2-content gas is then routed to a reduction step where it is combined with Claus off-gases and the sulphur compounds are reduced to H2S. The treated gas is then passed to a second column for the selective absorption of H2S and the unabsorbed gas is vented to the atmosphere. The fat solvent from both absorption columns is stripped in a common stripper and the stripped gas is passed to a Claus unit for conversion to elemental sulphur.

Abstract: ABSTRACT A beam deflection system is provided with electrical circuitry for adaptively correcting the deflection of a beam of radiant energy in a scanning system incorporating a rotating scanning mirror to compensate for misalignment in facets of the mirror.  With the use of an acousto-optic modulator providing a deflected beam at an angle dependent on the frequency of an acoustic drive signal, the orientation of the beam can be altered to compensate for the mis-aligned facets by varying the acoustic frequency.  A sensor and bridge circuit signal the position of a beam scan.  A memory stores the value of the frequency for scans by each facet, the value being altered with each scan to optimize the frequency.  A drift compensation circuit provides for an averaging of the parameter values, and provides a voltage to adjust the balance of the bridge to drive the average value towards a reference value.

Abstract: DATASET APPARATUS     ABSTRACT OF THE DISCLOSURE    A dataset apparatus is powered by voltages extracted from electrical signals passing between the data terminal apparatus and the dataset by circuits com-prising a capacitor and diode combination.  The trans-mitter of the dataset includes capacitance isolation of the signal from the transmission lines by applying an oscillated voltage and an inverted oscillated voltage dependent upon the signal to capacitors in a first cir-cuit to charge the capacitors through a diode whereby the oscillating voltage causes the capacitors to discharge through a second path formed by further diodes to charge a pair of capacitors coupled across the transmission lines.  A second circuit of similar impedance to the first charges the capacitors to the opposite polarity.  The arrangement can handle high common mode voltages on the transmission lines.  The receiver of the dataset inclu-des a doubly balanced resistance bridge network connec-ting the transmission lines to a differential amplifier, the circuit being balanced such that signals from the transmitter are not applied to the amplifier and also common mode signals are not applied to the amplifier.
