Abstract: A B S T R A C T          MATERIAL HANDLING AND SORTING SYSTEM      Mechanised mail sorting offices require packets to be sorted according to destination into one of many bags.  A typical mechanised system includes a loading mechanism for transferring packets from stationary input pockets onto a continuously moving sequence of containers which pass all destinations in turn and unload as required.  The system according to the invention consists of a number of separate self powered single trolleys (TL) which run on a tracking network.  Each trolley (TL) is adapted to be programmed with the route to be taken to the destination of the packet(s) loaded into it.  The trolley (TL) co-operates with en-route track-side signposts (TSB) enabling steering means (SM) in the form of a guide arm at the front of the trolley (TL) to guide the trolley around the tracking network to and from its required destination for unloading its package into a bag.  Programming is done by operators at induction stations (ISA, ISB, ISC and ISD) at sidings in the tracking network while the trolleys are stationary.

Abstract: Abstract of the disclosure:     The semi-continuous process according to the invention for digesting cellulose-containing material (substrate) with gaseous hydrogen fluoride comprises sorption and subsequent desorption of HF in a total of n steps.  The substrate is divided into n batches in n reactors (1a, 1b, 1c, ...);  each batch passes through the n process steps in one reactor (1a, ...).  Initially, sorption is carried out in the first to the  ?th step by the action of HF-inert gas mixtures, having an HF concen-tration which increases from sorption step to sorption step, at a temperature above the boiling point of HF. subsequently, desorption is brought about in the ( ?+1)th to nth step by treating with heated HF-inert gas mixtures having an HF concentration which decreases from desorp-tion step to desorption step; n is an even number from 4 to 12 and the n steps each take place in the same time segments (periods).  The sequence of steps is displaced by one period from each batch to the next batch.  During each period, the batch in the first step is connected to the batch in the last step and the batch in the second step with the batch in the penultimate step and the batch in the  ?th step with the batch in the (? + 1)th step, by HF-inert gas circulations.

Abstract: BRILLOUIN RING LASER      Abstract A Brillouin ring laser comprises a length of   optical fiber having first and second end portions and forming  a loop portion between  the  end portions.   A fiber  optic coupler is used to optically close the loop portion.  The length of the loop portion and the coupling constant   of the coupler are selected to form a resonant cavity.     A light  source  introduces  pump  light into the first end portion  to  provide  a pump  light wave which propagates through the loop portion.  The pump light wave circulates through the resonant cavity and increases in intensity to a level which is greater than the intensity of the pump light in the first end portion.   The intensity level in the  resonant  cavity  is  sufficient  to  cause  stimulated Brillouin scattering in the fiber loop portion to provide a Brillouin wave which circulates through the fiber loop portion in a direction opposite to that of the pump light wave,  and is shifted in frequency relative to the pump light wave.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to an overvoltage protector in an apparatus having two moving parts.  The parts are in mutual com-munication via a bearing, one part being stationary in relation to a substructure at ground       potential.  The moving part can be subject to a voltage and the stationary part is electrically connected to the earthed subsubstructure.   For preventing a cur-rent passing through the bearing between the parts,  an electri-cal insulator is provided in the current path through the bearing.          The moving part has a projection at a distance from an electrode connected to ground such that a spark discharge gap is formed be-tween mutually moving parts.  The bearings are protected against current by the electrical insulator up to a given voltage thres-hold.  In order that this voltage threshold will not be exceeded, the spark discharge gap comes into operation at a lower value than this voltage threshold and keeps the voltage difference between the parts at this lower value.

Abstract: Abstract of the Disclosure In track pin-type tracks or connector-type tracks the bearing systems for the track plates (1-3; 13-15) that can pivot about track pins (6) have a relatively short service life compared to the remaining components of the track.  It has been found that in addition to the loads caused by temperature, the type of loading caused by flexing of the track pins is of decisive importance.  By fabricating the track pins (30,35,37,40,44,43,52,55,60) of carbon fibre reinforced plastic with a modulus of elasticity of approximately 460,000 N/nm2 flexing can be considerably reduced in comparison to track pins of steel.  If the track pins are supported, for example, in rubber (5,63) or in metallic sleeves of bearing metal, this brings about an increased service life for the bearings because of an almost even distribution of the tensions and a significantly reduced level of tension.  In addition, track pins of carbon fibre reinforced plastic result in a weight saving of approximately a factor of 5 in comparison to steel.
