Abstract: A phase-controlled voltage regulator of the series type, for supplying A.C. and D.C. electric loads in electronic ignition systems for internal-combustion engines. The A.C. and/or D.C. electric load is connectable in series with a single winding magneto generator via a respective electronic control switch; the voltage existing on the electric load is continuously detected and set to a supply voltage value required by the load by controlling the start time, and the time length of activation of the electronic control switch, during each half-wave of the generator voltage having a same polarity, in relation to the detected voltage on the electric load itself; no-load operating conditions for the magneto generator are maintained during the initial period of time for each half-wave, inhibiting the conduction of the electronic control switch.

Title: Impact compactor
Inventor: MIJBURGH CHRISTOFFEL AVRIL
IPC: E02D3/026
Filed: 1998-05-15
Abstract: The invention concerns an impact compactor (10) which comprises one or more out-of-round compactor masses (14). The masses are moved rotationally over a soil surface, at an angular velocity suitable for normal operation, to apply periodic compaction blows to the soil surface. This is achieved by primary drive means. In the case of a towed impact compactor, the primary drive means is typically a tractor. The impact compactor (10) includes an auxiliary drive which is arranged to operate automatically, in response to a reduction of the angular velocity of the compactor masses below the angular velocity suitable for normal operation, to apply an auxiliary rotary drive that restores their angular velocity.

Inventor: CHEN TAI-ANN
IPC: H04J13/00
Filed: 2000-01-10
Abstract: In a wireless communication system, unique methods are presented to dynamically assign channel codes of different lengths in a manner to maintain orthogonality among assigned channels. In one embodiment of the method of the invention, channel codes that require relatively long-lengths are assigned from a first end of a list of unassigned channel codes and channel codes of a shorter length are assigned from an opposing end of a list of unassigned channel codes. Assignment of a shorter length code sequence is made if the longer-length channel codes that depend from the proposed shorter-length code sequence are available. In another embodiment of the invention, the availability of short length channel codes is derived directly from the availability of the longest length channel codes. In this embodiment of the invention, a group of longest-length channel codes that contain a common shorter-length code of the desired length are checked for availability.  If all the codes of the group are available then the common shorter-length code may be assigned to the transmission.      Further, in accordance with the methods of the invention by assigning transmissions that require longer-length sequences from a first end of a list of channel codes and shorter length sequences from an opposing end of a list of channel codes, the number of channels available for shorter length sequences is maximized.

Abstract: A method for producing a stabilized magnesium hydroxide slurry involving wet milling a starting magnesium hydroxide slurry. Also disclosed is a stabilized magnesium hydroxide slurry produced by the method and magnesia-based products produced from the wet milled magnesium hydroxide slurry. Washed magnesium hydroxide slurry is either (a) fed directly to a wet mill (1) at a controlled rate for particle size reduction, or (b) introduced to a disk filter (2) to increase percent solids to greater than about 60 %. If the disk filter (2) is used, the discharge is directed to a pug mill (3). Flow is recycled within the pug mill (3) through high-shear mixer (4). The pug mill discharge is collected in purge tank (5). A pump (6) is used to withdraw slurry from surge tank (5) and feed wet mill (1) at a controlled rate which rate dictates residence time in wet mill (1). This rate can be altered to control particles size reduction.  The milled slurry is collected in storage tank (7).

Abstract: L'invention concerne un distributeur pouvant distribuer le contenu fluide d'un contenant de telle sorte que des contaminants externes comme la poussière, l'air ou les microbes ne puissent pénétrer dans le contenant, même après plusieurs cycles de distribution. Ce distributeur est muni d'un clapet enfichable et d'un clapet à gaine élastomère (soupape à languette, soupape échancrée ou soupape en bec de canard, par exemple), qui sont tous des dispositifs antiretour. L'obturateur est muni d'un moyen qui le replace en position fermée à la fin de chaque cycle de distribution, ce qui en fait un dispositif également antiretour. Ce dispositif peut être une attache, un moyen de retenue par gravité ou la déformation élastomériques d'une pièce de robinet. L'obturateur peut être équipé de canaux ou autres entités découpées ou de forme telles que des rainures pour faciliter l'écoulement fluide. Le contenant de l'invention doit être réductible en volume et assurer ainsi sa propre pression interne à la fin d'un cycle de distribution. Dans une autre forme de réalisation, le clapet de l'invention peut être fabriqué sans soupape de refoulement (soupape à languette, soupape échancrée ou soupape en bec de canard). Dans ce cas, l'obturateur est le seul mécanisme de soupapes antiretour.

Title: Encoding multiword information by wordwise interleaving
Inventor: VAN DIJK MARTEN E
IPC: G06F9/44
Filed: 1999-07-19
Abstract: Multiword information is based on multibit symbols disposed in relative contiguity with respect to a medium, and is encoded with a wordwise interleaving and wordwise error protection code for providing error locative clues across multiword groups. In particular, the clues originate in high protectivity clue words (BIS) that are interleaved among clue columns, and also in synchronizing columns constituted from synchronizing bit groups. The synchronizing columns are located where the clue columns are relatively scarcer disposed. The clues are directed to low protectivity target words (LDS) that are interleaved in a substantially uniform manner among target columns which form uniform-sized column groups between periodic arrangements of clue columns and synchronizing columns.
