Title: Wide-necked cask of plastic and a process for the production thereof
Inventor: SCHUETZ UDO
IPC: B29C49/04
Filed: 1991-10-28
Granted: 1995-11-07
Abstract: The wide-necked cask (1) that is of thermo-plastic and which was developed with the aim of achieving minimal space requirement when transported empty has, as an important feature, a conical body section (2) which makes it possible to stack a number of such casks one inside the other; this also incorporates a reinforcing and storage safety ring (11) that is arranged just beneath the cask rim (3) and a foot ring (14).  In the extrusion blow moulding process that is used to produce the wide-necked cask, a closed double-cask body with two conical body sections (2), two cask rims (10) and a middle ring is blown.  After the removal of the double-cask body from the mould, this is divided into two casks (1) by cutting out the middle ring, and then this middle ring is shrunk onto a cooled cask (1) as a storage safety ring (11).

Abstract: A system (10) and method for treating a fluid carrying a contaminant to which a photoactive material has been bound include a treatment device (12) that defines a flow passage (36) with a dap (28). The system and method operate to establish a flow of fluid from the inlet (38) end of the gap (28) to the outlet end (40) of the, gap (28). The system and method also channel he flow of fluid in the gap (28) in succession through one or more paths. The system and method esta-blished at least two discrete sources of ra-diation (30), in the flow path (36) at spaced, apart locations along the direc-lion of fluid flow. At least one of the ra-diation sources (30) comprises a photodi-ode. The system and method further in-clude a control far operating each dis-crete source of radiation at a selected wavelength within the prescribed range to activate the photoactive material bound to the contaminant. Upon activa-tion, the material eradicates the contami-nant. The system and method provide ex-tracorporeal treatment of fluids like blood to quickly and effectively eradicate infection agents at relatively high flow rates.

Title: Process for the gas-phase polymerization of alpha-olefins
Inventor: GOVONI GABRIELE
IPC: C08F210/06
Filed: 1993-02-01
Granted: 2006-07-18
Abstract: The present invention relates to a process for the production of polymers and copolymers of olefins CH2=CHR, wherein R is a hydrogen atom or an alkyl or aryl radical having a number of carbon atoms of from 1 to 10, comprising at least one (co)polymerization step in the gas phase, in the presence of a highly active catalyst obtained from a titanium compound supported on a magnesium halide in active form and an Al-alkyl compound. The process is characterized by the fact that it is carried out by feeding a small amount compared with the polymer of a compound having at least two groups, same or different, capable of reacting with the alkyl aluminum compound and able to selectively inhibit the reactivity of the polymer particles fine compared to the average granulometric size of the polymer present in the gas phase.
Patent CA-2091210-C (CA)
Inventor: PAJTAS SCOTT ROBERT
IPC: B29C33/76
Filed: 1993-03-08
Granted: 1998-10-13
Abstract: The relatively harsh "ride" of a non-pneumatic tire ("NPT") is greatly improved by a ring of elastomeric material referred to as a "ride-enhancing insert" ("RI"). The RI is pre-positioned on the outer surface of a wheel rim on which the NPT is to be molded of elastomeric material, most preferably a polyurethane, which is peculiarly well-suited to survive normal use on various vehicles, particularly as a replacement for a conventional spare tire, or "minispare" in an automobile. The RI is surprisingly tolerant of stress and heat loads generated by operation of the NPT/RI. The RI has a large effect on the spring rate of the NPT when deflected over a cleat, and a reduction in spring rate when deflected over a smooth laminar surface. This is of particular importance since the deflection over a cleat is where the improvement in ride is most noticeable. The degree of ride-enhancement can be tailored by choosing the size and shape of the RI, along with the physical properties of the elastomer from which it is formed.

Patent CA-2097152-C (CA)
Inventor: LIU QINGLI
IPC: H04B7/08
Filed: 1993-05-27
Granted: 2001-10-30
Abstract: A diversity receiver employing maximum-likelihood-sequence estimation employs a separate channel estimator (44-1, ... , 44-L) for each of a plurality of diversity channels. Each channel estimator (44-1, ..., 44-L) produces channel-model parameters ([f ~], ..., [f~~]) that characterize their respective channels. A weighting-and-accumulation circuit (56) computes the responses of the thus-represented models to candidate symbol sequences, and metrics indicating the likelihoods that respective candidate sequences were the sequences actually sent are determined by comparing the model output with the received signal in a comparison circuit (58) and squaring the magnitudes of the results in a squaring circuit (60). The receiver then employs a Viterbi algorithm (62) to determine which sequence is the one most likely to have been sent. In one version, it does this on the basis of the metrics calculated for the channel whose signal is strongest, while it determines the metrics by combining partial metrics from all of the channels in another version.

Abstract: 28   Pour augmenter le débit de transfert d'information d'une base (1) audio-visuelle à des demandeurs (9-11) multiples on propose, lorsqu'une requête a été effectuée par un demandeur, de ne pas satisfaire ce demandeur immédiatement mais de le faire attendre pendant une période donnée (17). Pendant cette période on détecte quels sont les autres demandeurs qui demandent la même séquence. Au bout d'une période d'attente on diffuse (22) à l'ensemble (19) de ces demandeurs la même séquence. On montre qu'en retardant un peu la diffusion on augmente dans des proportions très importantes le débit réel de diffusion de la base de données et sans par ailleurs avoir à modifier la technologie d'extraction des données de cette base.

Abstract: A mechanism and method for the continuous winding of a web of paper (w) into rol ls including a shear type load cell (32, 32a) for measuring the horizontal component of the reactive force on the winding drum with the output of the load cell being used to control the nip pressure (N) between the winding drum (15, 15a) and the roll being wound. Another load cell (39) measures the tension of the incoming paper web, and this measurement is subtracted to give th e net nip pressure. An initial reading is taken when the core on which the web is to be wound is lowered onto the load cell (41) and an initial reading is taken to provide the index point of the weight of the core (18, 18a) and reel, and when the core is b eing pivoted downwardly over the drum (15, 15a), the vertical and horizontal components with the total nip load (N) are calculate d to control the nip load. Thus, the nip load is carefully controlled at all positions to provide an improved drum winder obtaini ng controlled nip load and controlled density of the roll being wound.
