IPC: H04B10/50
Filed: 1987-05-26
Abstract: An optical transmission system comprises a plurality of 
optical transmitters (10,12,14,16) coupled by a common channel or bus 
to an optical receiver. The optical transmitters (10,12,14,16) are 
operated using TDM (time division multiplexing), each TDM period being 
word or message length. The optical transmitters each comprise at 
least one current source (12,14) to drive the light source (10), for 
example a laser, in response to the data signal, to vary its output 
power about a steady level which is an average of the maximum and 
minimum values. The or each current source (12,14) may be so 
controlled as to increase its output gradually (preferably 
sinusoidally) to reach the aforesaid mean level at the beginning of a 
TDM period and to decrease it in the converse way after the period 
ends. Such an arrangement avoids the need for guard time before and 
after the TDM time period, thereby increasing channel efficiency, and 
improves receiver (40-48) sensitivity by reducing quantum or shot 
noise due to steady light from inactive transmitters.

Title: Refuse vehicle
IPC: B65F3/20
Filed: 1989-02-16
Abstract: In refuse vehicles having a refuse-filling system arranged behind the driver's cab, an adjacent refuse-compressing device and a refuse-collecting container arranged behind the latter, it was hitherto not possible to achieve adequate compression of the filled refuse inside the refuse-collecting container, resulting in insufficient utilisation of said container. 
<??>In the case of the invention, there is arranged in the range of action of the refuse-compressing device a counterpressure plate which can be subjected to a pressing force and is mounted in a radially swivellable manner on the ceiling of the refuse-collecting container, said plate forming a counterpressure element for the filled refuse. In this way it is possible to compress, in a uniform manner, the refuse filled into the refuse-collecting container from the start of refuse feeding until said container is completely full and thus an increased utilisation or useful load of the refuse vehicle can be achieved.

Patent EP-0344760-A3 (EP)
Title: Recovery and concentration of aqueous acids and bases
IPC: C02F1/46
Filed: 1989-06-01
Abstract: A process for removing and recovering a dissolved substance, either acid or a base, from an aqueous feedstream. The feedstream is contacted with an aqueous dispersed phase containing liquid membrane emulsion which removes the dissolved substance to the degree desired from the feedstream and absorbs it into the liquid membrane emulsion. The aqueous dispersed phase of the emulsion comprises a reagent which reacts with the dissolved substance by neutralization, allowing the dissolved substance to accumulate to a significant concentration in the emulsion before the spent emulsion is separated from the treated feed and coalesced into a membrane and a spent aqueous internal reagent phases. The spent aqueous internal reagent phase is subjected to electrolysis in a bipolar membrane cell which regenerates the dispersed reagent loaded internal aqueous phase in a composition suitable for recycle to emulsification and further feedstream treatment. The bipolar cell also generates an aqueous stream rich in dissolved substance from which the extracted dissolved substance can easily be recovered in pure form by conventional separation means.

IPC: C01F7/473
Filed: 1989-06-02
Abstract: Die Erfindung betrifft ein Verfahren zur Entfernung des Natrium­
oxalats aus einer alkalischen Aluminatlauge des Bayer-Prozesses.  
     Zuerst erfolgt die Wäsche des gesamten Aluminiumhydroxid-Produk­
tes aus der Ausrührung, um alles kristalline Natriumoxalat zu 
entfernen, wodurch eine weitere Ausfällung von Natriumoxalat in 
den Aluminiumhydroxid-Ausrührern verhindert wird. Dadurch steigt 
die Konzentration des gelösten Natriumoxalats auf eine Höhe, 
welche zur ökonomischen Entfernung von Natriumoxalat durch Kri­
stallisation aus einem Nebenstrom führt. Ein teurer Eindampfungs­
schritt ist deshalb nicht mehr erforderlich. Das Natriumoxalat 
wird in einer Menge entfernt, die dem während des Bauxitauf­
schlusses neu gebildeten Natriumoxalat entspricht. Auf diese 
Weise wird eine konstante Konzentration des gelösten Natrium­
oxalats in der Aluminiumhydroxid-Ausrührung aufrechterhalten. 
Zusätzlich kann die Aluminiumhydroxid-Ausrührung (im Zustand 
ohne kristallines Natriumoxalat) durch Zugabe kleiner Mengen 
eines organischen Polymeren stabilisiert werden.

Title: Polyorganosiloxane
IPC: C08G77/20
Filed: 1989-06-30
Abstract: A novel polyorganosiloxane is here disclosed which has 
a fluorine atom-containing substituent at one terminal of 
its molecular chain and an unsaturated double bond-­
containing substituent at the other terminal thereof. The 
polyorganosiloxane of the present invention is represented 
by the general formula (I) 
  
wherein j is an integer of 1 to 2000, and R¹ is an 
unsaturated double bond-containing group, each of 
R² and R³ is an alkyl group having 1 to 4 carbon 
atoms, phenyl group, vinyl group, straight-chain 
or branched alkenyl group having 2 to 18 carbon 
atoms, or a siloxane chain which is similar to 
 
 
  
and R⁴ is a fluorine atom-containing substituent, 
  
wherein R¹° is similar to R⁴ and is the fruorine 
atom-containing substituent, R¹¹ is an alkyl group 
having 1 to 4 carbon atoms or phenyl group, and 
the oxygn atoms sited on the right side of the 
above formulae are combined with a siloxane chain 
having the unsaturated double bond-containing 
substituent at the terminal thereof which is 
similar to 
 
 
   
     The polyorganosiloxane of the present invention can be 
used for the modification of synthetic resins and silicone 
rubbers, and in the polyorganosiloxane, a fluoroalkyl group 
or the like is present at the terminal of the molecular 
chain which is most distant from a reactive group capable to 
chemically combining with the rubbers and the like. In 
consequence, a degree of freedom is great, and the employ­
ment of the fluoroalkyl group in a small amount permits 
improving surface properties of the synthetic resins and 
silicone rubbers, and providing them with oil resistance and 
solvent resistance.
