Inventor: ANDERSSON LENNART
IPC: D21C9/10
Filed: 1992-04-29
Abstract: The present invention relates to a process for delignification and bleaching of chemically digested lignocellulose-containing pulp, wherein the pulp is acid treated at a pH of between about 1 and about 6, whereupon a water-soluble mixture of a magnesium compound and a calcium compound is added at a pH of between about 1 and about 7 before the pulp is treated with a chlorine-free bleaching agent.

IPC: C07C59/56
Filed: 1988-06-10
Abstract: A novel three-step process for preparing 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid is disclosed, which involves (1) reducing 4-(3,4-dichlorophenyl)-4-ketobutanoic acid to 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid; (2) then converting the intermediate hydroxy acid formed in the first step to 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone, and (3) thereafter reacting the resulting gamma-butyrolactone compound with benzene in a Friedel-Crafts type reaction to form the desired final product. The latter compound is known to be useful as an intermediate leading to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone and ultimately, to cis-(1S)(4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrah ydro-1-naphthaleneamine (sertraline), which is known to be a preferred anti-depressant agent in the field of medicinal chemistry. The aforementioned 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone and 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid are both novel compounds. There is also disclosed a novel process for converting 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone directly to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone, as well as an alternate novel process for converting 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid directly to this same key intermediate.

Title: Sharps collector.
Inventor: PACKER GILBERT
IPC: B65F1/16
Filed: 1992-11-03
Abstract: A sharps collector (10) comprising a container for holding, storing, and disposing syringes. The sharps collector includes a disposable receptacle (12) and a decorative cover (14). The receptacle preferably has two elongate apertures (40) and chutes (54) associated wit each aperture (40) and chutes (54) associated with each aperture (40). The chutes (54) are designed to guide syringes into the receptacle (12) once the syringes pass through an aperture (40). The chutes (54) also obstruct syringes which are already contained in the receptacle (12) from protruding or re-emerging out of the receptacle (12). The decorative cover (14) is reusable and fits over and attaches to the receptacle (12). When the cover (14) is attached to the receptacle (12), it conceals the apertures (40) and chutes (54) of the receptacle (12). The cover (14) includes an elongate aperture through which a shuttle is accessed. The shuttle (16) directs syringes to the concealed apertures (40) and chutes (54) of the receptacle (12). The syringes to be disposed are placed in the shuttle (16) and the shuttle (12) is manually shifted such that a syringe is pushed towards an aperture (40) and chute (54). The syringe then falls through the aperture (40), is guided by the chute (54), and ultimately falls into the receptacle (12) and is contained within the collector (10). The cover (14) can be detached from a receptacle (12) when that receptacle (12) is ready to be discarded. <IMAGE>

Abstract: A push fit coupling for non-metallic gas pipes comprises a hollow metal body 1, an end of which is arranged to receive a non-metallic gas pipe 50. The body comprises a crushable ring 24 within the body having a frustro-conical outer surface (30, fig 4), and a non-metallic sleeve 32 having a frustro-conical inner surface 40, and means to prevent withdrawal of the sleeve from the body. The sleeve and ring act together so that any force acting to separate the pipe from the coupling causes the inner surface of the sleeve to act on the outer surface of the ring, so as to force the ring to engage the outer surface of the gas pipe more tightly. A protective collar or sheath 60 may surround the gas pipe.

Title: Correlating a digitised UWB signal with a reference UWB signal
Inventor: BAKER DAVID
IPC: H04B1/69
Filed: 2003-07-18
Granted: 2005-12-21
Abstract: A receiver of ultra wideband (UWB) pulse samples incoming signals via an analogue-to-digital (A/D) converter (518) and correlates it (514) with a received reference signal (518) in order to compensate for distortion and multipath reflections (fig. 4b). Digitising the received UWB signal allows the use of digital techniques which decrease the cost, size and power consumption of the receiver. A pattern generator further controls the stored signal in order to provide reference signals for two or more successive pulses with interleaved multipath components, allowing communication over eg. power lines. The received signal can be adjusted in response to the reference signal. The data can be encoded according to both the position and the phase of the pulse.
