Title: Mounting of capacitors in electrical control box
Inventor: OLIVEIRA DE BARROS DANIEL ALES
IPC: H02K17/30
Filed: 1998-09-16
Abstract: Apparatus for alternatively mounting either a large cylindrical capacitor having a given length and a given diameter or a small cylindrical capacitor having a given length and a given diameter. The apparatus includes a substantially planar support wall having two or more substantially U-shaped support walls extending substantially perpendicularly therefrom. The U-shaped support walls are parallel to one another and are spaced from one another by a distance such that at least two of the U-shaped walls will span the given length of either of the capacitors. Each of the two or more U-shaped walls defines an upwardly facing capacitor support surface. Each of the support surfaces has a lower arcuate section extending between left and right end points. The lower arcuate sections have an effective diameter, which is substantially equal to the given diameter of the small capacitor. Each of the support surfaces has two upper arcuate support sections, one of each of the upper sections extends from each of the left and right end points of the lower arcuate support section. Each of the upper arcuate sections has an effective diameter substantially equal to the diameter of the large capacitor.

Title: Concrete panel construction system
Inventor: DILORENZO NICK
IPC: E02D29/02
Filed: 2000-06-09
Abstract: A concrete building panel has a slab and a plurality of ribs and beams. A series of horizontal holes in the end ribs are spaced at a selected constant spacing such that adjacent panels may be fastened together through them. In one type of panel, the slab is separated from the ribs to provide an air gap. Connections between holes in two adjacent concrete wall panels are made by a hollow conduit having an abutment at either end to engage the concrete wall panels. Other connections between adjacent panels involve a stitch with legs which extend through holes in the beams. Other connections involve a space made by vertical channels of horizontally adjacent panels. A plate fitted into the space aligns the adjacent panels and may extend upwards to align upper panels. Load bearing horizontal holes through the ribs are reinforced with reinforcing bar in the concrete arranged in generally triangular shapes. The concrete panels are formed in a form with sub-forms aligned by rods which create horizontal holes of the desired size and placement when removed.

Title: Vibrator drive
Inventor: BRAUNGARDT RUDOLF
IPC: B28B1/087
Filed: 2000-08-18
Abstract: The vibrating drive is especially suited for a mold for producing concrete moldings and consists of at least one piezoelectric vibration exciter which is located stationary on the mold. The vibration exciter is formed by a housing in which an unbalance mass is movably supported and is drive-connected to a piezoelement which is likewise located with a vibration capacity in the housing. By applying an AC voltage to the vibration exciter, a deformation motion is formed which is converted into an oscillating motion of the unbalance mass and which thus produces vibrations of the mold. By using a different number of vibration exciters which can be made relative small and compact in dimensions, and by their attachment to different points on the mold with a horizontal and/or vertical direction of vibration, the vibrating drive and thus the vibration behavior of the mold can be adapted to different operating conditions.

IPC: E03D13/00
Filed: 1998-12-30
Abstract: According to the invention, a pan (17) in which urine (35) accumulates is used in the water-less urinal (1). A float (33) floats on the urine (35), and is pressed upwards by the buoyancy thereof against an opening (31) in the cover (29) of the pan (17).

Title: Manufacture of 3-hydroxypropionitrile
Inventor: RUETTIMANN AUGUST
IPC: C07C253/30
Filed: 2001-01-24
Abstract: A process for the production of 3-hydroxypropionitrile comprises (a) reacting acrylonitrile with water in a molar ratio of about 1:0.5 to about 1:20 in the presence of a weak base under specific temperature and pressure conditions until a conversion in the range of about 40% to about 80% has been achieved in order to obtain a two-phase organic-aqueous mixture, the organic phase of which consists mainly of bis(cyanoethyl) ether and 3-hydroxypropionitrile as well as a relatively small amount of unreacted acrylonitrile, and the aqueous phase of which consists mainly of an aqueous solution of the weak base; (b) after cooling the mixture obtained in (a) separating off its aqueous phase; (c) distilling off the acrylonitrile from the organic phase remaining after (b) in order to obtain a mixture consisting mainly of bis(cyanoethyl) ether and 3-hydroxypropionitrile; (d) subjecting the mixture obtained in (c) to a pyrolysis carried out under specific temperature and pressure conditions in the presence of a basic catalyst selected from the group consisting of calcium, magnesium, strontium, titanium, iron and zinc oxides, alkali metal acetates, alkali metal formates, alkali metal and barium carbonates, alkali metal bicarbonates, calcium and copper hydroxides, di- and trisodium phosphates, sodium fluoride, sodium silicate and high boiling trialkylamines in order to obtain a mixture consisting mainly of 3-hydroxypropionitrile and acrylonitrile; and (e) isolating the desired 3-hydroxypropionitrile by fractional distillation from the mixture obtained in (d). Such a process which has recyclization of the basic aqueous phase as well as of the acrylonitrile which is distilled off represents a preferred embodiment. A further aspect of the present invention consists in that, after the about 40% to 80% conversion has been achieved in process step (a), the weak base is neutralized by the addition of a weak acid in order to obtain also in this case a two-phase organic-aqueous mixture, which instead of the original weak base contains base formed, inter alia, by the neutralization; this base represents the basic catalyst already used in the later process step (d), so that a special addition of a basic catalyst for process step (d) is avoided. The thus-produced 3-hydroxypropionitrile is an important intermediate in a process for the manufacture of panthenol, which, in turn, especially in the form of its d(+) isomer, is a valuable agent for the treatment of dermatoses, burns and infectious ulcers as well as a valuable additive in shampoos and other cosmetics.

Patent CA-2339902-A1 (CA)
Inventor: DON-CAROLIS CEDRIC
IPC: H04Q11/00
Filed: 2001-03-07
Abstract: A data format and control protocol for a communication system is presented which allows purely photonic connections between network edge components. The format uses time slot based TDM channels to allow all optical switching of the channels between different signal paths in the switch nodes, and time slot by time slot WDM to reduce the probability of blocked connections. The connection protocol uses conventional 'least cost' path calculation algorithms to identify target connection routing through the network, a path integrity process to ensure capacity, and link removal and recalculation in cases of blocked connections. The time slot and wavelength map can be represented as a two dimensional matrix. Availability calculations can be done using simple matrix logic operations.  System operation with bands of optical wavelengths is discussed.
