Abstract: The invention relates to a power supply set for a tube of the type requiring both a cathode supply and a collector supply, especially for a travelling wave tube, and comprising: - collector polarising means (4), operating substantially as a voltage source, delivering between collector (2) and cathode (1) a voltage (Vc) which is filtered and regulated to a slight extent or to no extent whatsoever, these means having one of their terminals connected to the cathode and the other to the collector, - cathode polarising means 8, delivering at the cathode a voltage (Vk) which is highly regulated and highly filtered so as to maintain the potential of the cathode constant at its selected operating point, and - a charge storage capacitor (10), one plate of which is connected to the cathode and the other to ground. …<??>According to the invention: - the cathode polarising means (8) have one of their terminals connected to the collector (2) and the other to ground, and - the collector polarising means (4) are connected in series with the cathode polarising means (8) and intercalated between the latter and the cathode (1), so that the cathode voltage (Vk) is equal to the sum (Vc + Vg) of the voltages delivered respectively by the collector polarising means and the cathode polarising means. …<??>In this manner, the cathode polarising means (8), while essentially undertaking on their own the regulation of the cathode voltage, deliver a voltage (Vg) which is significantly less than the cathode voltage (Vk) and a power which is significantly less than the cathode power.

Patent EP-0381952-A1 (EP)
Inventor: BUNZ GEORG
IPC: A44C11/02
Filed: 1990-01-16
Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp. With the exception of the spring and sleeve, no other movable parts are required.

Abstract: A baling machine for forming large cylindrical bales of crop, e.g. straw, has a baling chamber (56) in which the straw is rolled into a bale by oppositely moving runs (52, 54) of belts (48). The baling chamber (56) is fed by a unit (60), picking the crop up from a windrow (160), via a feeder fork mechanism (62). 
     In order to reduce blocking at the feeder fork mechanism (62) of brittle straw, tines (106) of the mechanism (62) which advance the crop in a cycle are mounted on crank pins (117, 119, 121, 123) of a crankshaft (124). Thus, for example, if the crankshaft (124) has four such crank pins disposed at equal angular intervals around it, a part of the crop will be advanced four times for each rotation of the crankshaft.

Abstract: High octane gasoline and high quality distillate are co-produced by a hydrocracking light cycle oil from a catalytic cracking process under conditions of low to moderate hydrogen pressure and severity to produce a high octane, hydrocracked gasoline. The distillate fraction from the hydrocracker is separated to form a first fraction which boils immediately above the gasoline fraction and a second, higher boiling fraction which is withdrawn as product. The first distillate fraction is recycled, preferably to extinction, to the cracker to increase the paraffinic content of the higher boiling distillate product by removal of the hydroaromatic components in the recycled fraction. The recycled fraction may be mixed with fresh feed to the cracker or may be injected at a higher level in the cracking riser as a secondary feed injection. The paraffinic distillate product has a low sulfur content and a high cetane index and is useful as a road diesel fuel.
