Abstract: A speed reducer having an orbitally driven rotor, mounted for free rotation on a rotor drive wheel driven along a rotary path by a drive shaft, has a perimeter defined by an epitrochoidal curve that simultaneously engages each of a series of rollers arranged in a circle around the rotor, the number of lobes on the rotor being one less than the number of surrounding rollers. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes.The rotor drive wheel is driven by a compensation coupler that prevents radial forces of the rotor and the rotor drive wheel, such as may be generated as a result of inaccuracies in machining, temperature changes, etc., from being transmitted to the drive shaft where they could be translated into large forces. With the present arrangement, the drive shaft provides only a rotary thrust on the rotor drive wheel and is shielded from reaction movements of the rotor and rotor drive wheel.The rotor drive wheel is driven along an orbital path by a variable-length crank arm that extends into a radial opening in the rotor drive wheel and makes sliding engagement with opposite faces of the radial opening. The driving surfaces that engage the faces of the radial opening form, in a plane perpendicular to the axis of the drive shaft, arcs of a circle equal in diameter to the width of the radial opening. The radial opening is long enough to permit the rotor drive wheel and the rotor to follow the requisite orbital path. The crank arm includes an expansion slot that divides it into two fingers that embrace opposite sides of the radial opening. For smaller units, the spring quality of the fingers is relied upon to maintain firm engagement between the fingers and the faces of the slot. In larger units, an adjustment screw permits changing the spacing between the fingers to precisely fit the width of the crank arm to the width of the radial opening. In either case, the only radial forces on the drive shaft are those generated by the torque of the drive shaft.

Abstract: 1.

Abstract: A simple and efficient sealing means for a door lacking a threshold and which does not require any major recessing in the door leaf comprises a lath (11) of resilient material, which with a substantually plane main portion (15) is attached to the lower edge of door leaf (10). A head (16), enlarged with respect to the main portion, is provided with sealing ridges (19) and may be bent in relation to the attachment of the lath, so the ridges will be forced towards the floor. 
<??>An actuating member (29) comprising a longitudinally compressible leaf spring is fitted between the lower edge of the door leaf and the head (18) of the lath, so it extends outside the vertical hinge edge of the door leaf. Just before the door reaches its closed position the leaf spring contacts the door frame, and will then force the portion of the head adjacent to the hinge edge downwards. During the terminal portion of the closing movement the friction between the floor and the downwardly turned portions of the ridges will <<roll>> the head to full contact with the floor.

Abstract: The polarized, electromagnetic relay includes a magnet frame, relative to conduit rabbets, with angles-off yoke arrangement, which includes two separated, parallel-arranged yokes, as well as a permanent magnet that lies therebetween and between anchor plates. The two yokes are L-shaped and formed exactly identical, whereby their core shanks stretch over the entire length of the exciter coil, and lie next to each other in the region of the exciter coil. Thereby a mechanically and electrically absolutely symmetrical magnet frame results, whose asymmetry is compensated by losses arising from the air gap. Through the use of individual yokes there ensues a simple assembly in the spring jack, which functions as holding element for all of the parts.

Abstract: The feed gas is partially burnt with oxygen-containing gas in a thermal Claus process plant, in which temperatures in the range of 850 DEG  to 1350 DEG  C. is maintained. Product gas which has been produced is passed through a catalytic Claus process plant (Claus catalysis plant), from which sulfur is withdrawn. The exhaust gas from the Claus catalysis plant is supplied to a desulfurizing plant. The sulfur compounds in the exhaust gas of the desulfurizing plant are converted to SO2 in a thermal aftertreating unit. When the rate of the H2S-containing feed gas is below a limit, which is between 20 to 35% of the total rate of feed gas permissible for the thermal Claus process plant, then recycled exhaust gas from the desulfurizing plant (recycle gas) is admixed to the feed gas at such a rate that the rate of the mixed feed and recycle gases exceeds that limit. The recycle gas is suitably heated to 200 DEG  to 400 DEG  C. before it is mixed with the feed gas.

Abstract: A combinatorial circuit component for television sets with an overload protection circuit on the primary side and a secondary-side regulating circuit and starting circuit with final disconnection of the mains section. The protective circuit, which comes into play in the event of anomalies on the primary side, causes a jump in the negative voltage on the secondary side. This is compared with a secondary (standby) voltage, created independently of the combinatorial circuit, in a comparator, which supplies a control voltage to which the secondary protection circuit responds thus interrupting the excitation of the switch in the mains section.

Abstract: A drive line (26) for an implement (14) attachable to a tractor (10) includes two double cross bearing universal joints (32 and 34). During turns between passes over crop the power delivered by the line must turn through a working angle as large as 90 DEG . but for such a tight turn each joint turns the power through two angles of only 22 1/2 DEG  thus enabing full power to be used between passes without undue wear. The implement (14) is attached to lower links (18) of the tractor (10) by way of a yoke (16) which in turn is connected to a drawbar (12) of the implement (14) via a pair of channel-shaped supports (20, 22) rigid with, and at right angles to, one another. One support (20) receives the forward end of the drawbar (12) in its channel and is connected thereto by a vertical pivot pin (21). The other support (22) similarly receives the yoke (16) to which it is connected by a horizontal pivot pin (23). There is thus provided a drive and an arrangement for attaching the implement (14) to the tractor (10) which permits tight turns to be made efficiently.

Abstract: This apparatus uses as transmission medium the lines of electricity supply systems and allows simultaneous communication between a multiplicity of transmitters 1, 2, 3 and receivers 4, 5, 6, 7 without mutual interference. This multiple access apparatus is resistant against interference inherent in the mains, particularly against interference or attenuation which only relates to a part of the transmission frequency band. To achieve this, a multiplicity of discrete frequencies is used from a set of frequencies preferably above the audio frequency range. From this set, the instantaneous transmitting frequency of each transmitter is selected in accordance with a predetermined plan and in accordance with a timing pattern, common to all transmitters 1, 2, 3 and receivers 4, 5, 6, 7, which is preferably derived from the mains voltage frequency, and is varied in hops. Each transmitter 1, 2, 3 has its own pattern of variation, with the aid of which it can be selectively received by the receiver(s) 4, 5, 6, 7. <IMAGE>
