Title: Synchrotron particle beam position information transmission system - conveys from many probes to one remote control unit
Inventor: KAMMERLANDER KARL
IPC: H05H7/00
Filed: 1974-04-16
Abstract: The particles are accelerated in the synchrotron in a beam of which the position is checked by means of many X and Y pairs of probes. Because of the high particle speeds, a basic signal of 200 MHz is detected at a pair of probes, with the signal larger if the beam travels nearer a probe and smaller if further away. The control system operates to keep the signals from both X probes and both Y probes equal, which indicates that the beam is central. The central control generates a 400 KHz clock, using a crystal oxide oscillator and frequency dividers. This is transmitted on symmetrical lines to each probe control unit, where the monitoring of the X probe pair is switched at 400 KHz.

Title: Feeding fibres to the carding roller of a ringless spinner - using a toothed roller and rods which move the fibres from the teeth
Inventor: LEINEK ALBERT ARTUROVICH
IPC: D01H4/32
Filed: 1974-04-17
Abstract: An appts. for feeding a fibre lap to the carding roller, of a ringless spinning machine comprises a feed in plate and a novel feed roller above the plate which on rotation feeds the lap to the carding roller of the assembly. Alternating with the teeth of the feed roller are rods which extend parallel to the axis of the roller. A pair of supports mounted at each end of the roller carry the rods. As the lap moves under the roller and is penetrated by the teeth, the rods bend over the lap but push it away it away from the teeth as the teeth and rods rotate away from the lap. To increase the number of teeth which penetrate the lap at any one time, for increased speed of production, a vertical, rounded strip is placed in front of the roller so that as the lap slides over the strip it makes contact with the roller at an angle. A weighted roller in front of the strip presses and tensions the lap on the feed plate.

Title: Steroid 17-spirolactones prepn. - by treating corresponding gamma-hydroxy-propionic acid dimethylamide cpds. with acidic cation exchangers
Inventor: KLEIN UWE
IPC: C07J41/00
Filed: 1974-05-22
Abstract: Steroid spirolactones of partial formula (I) e.g. 3'-(3-methoxy-1 7 beta-hydroxy-1, 3, 5-(10)-oestratriene-17-yl)-propionic acid (1' 17)-lactone, are prepd. by treating corresp. gamma-hydroxy-propionic acid dimethylamides of partial formula (II), with acidic cation exchangers. The prods. are either biologically active or are intermediates for known biologically active cpds. Thus, 3'-(17 beta-hydroxy-4-androsten-3-on17a-yl)-propio-(1' 17)-lactone may be converted by 6-dehydrogenation and reaction with thioacetic acid into the known aldosterone antagonist 3'-7 alpha-acetylthio-17 beta-hydroxy-3-oxo-4-androsten-17 alpha-yl)-propio-(1' 17)-lactone. The reaction is simple to carry out at room temp., and pure products can be isolated by simply concentrating the reaction mixt. Ketal groups used to protect keto groups during previous reactions are split off during the lactonisation, thus avoiding the need for a separate deprotection step.
