Patent BE-894571-A (BE)
Title: Pedal driven vehicle or skate-board - incorporates spring suspension allowing shock forces to be transmitted to drive to assist forward movement
IPC: B62M1/00
Filed: 1982-10-01
Abstract: The drive for a self propelled device which can be based on the design of a skate board or scooter includes a spring which transfers shock forces to the drive so as to assist it. Between a base and a foot support is a helical spring at the pivot end and a belt drive at the front end. The base has wheels attached at front and rear. Pressure on the foot support drives the belt, and this is assisted by movements due to uneven ground. Other pedal driven vehicles include conventional shock absorbers between frame members which similarly allow shock forces to assist the chain drive.

Abstract: ABSTRACT OF THE DISCLOSURE      A  digital, abridged spectrophotometer with a detecting head having a housing with a viewing port and a light source. At least five photo-responsive devices, which in one embodiment may be filtered photo-diodes, are mounted in the head for each receiving light from a sample or standard in the viewing port. A standard sheet of Vitrolite* is mounted on the housing for movement with a plunger, which trips a switch, to cover the viewing port, while a standard black sheet can be pivoted to cover the viewing port for the calibration which precedes each reading. A digital computer calculates the values from the signals produced by the photo-diodes and provides signals for a display of the color values.  The computer has a memory in which signals corresponding to standardized reflectance values of at least one standard sample in different wavelength ranges  are stored, a first processing circuit which compare the signals corresponding to the standardized reflectance values to signals corresponding to the reflectance values of the standard sample provided in the port, and which stores correction signals corres-ponding to the result of the comparison, and a second processing circuit which after the exchange of the standard sample by the sample to be measured converts the non-corrected signals corres-ponding to the reflectance values of the sample to be measured by means of the correction signals to corrected signals corres-ponding to the reflectance values of the sample to be measured.

Abstract: INTRAUTERINE CONTRACEPTIVE DEVICE OF C OR OMEGA FORM   WITH TUBULAR INSERTER AND METHOD OF PLACEMENT                 ABSTRACT OF THE DISCLOSURE    An intrauterine contraceptive device made from plastic having a C-shape or Omega-shape to enable it to lie in the uterine cavity.  Lines of predetermined length are attached at one of their ends respectively to enlargement  portions of the terminal ends of the device and with their other ends fastened by a plastic bead and aid in insertion, removal and as a telltale marker.  The device can include a metallic contraceptive material such as copper.  One embodiment uses copper wire, which can be of selected different diameter, wound on the body of the device and retained against slippage by serrations on the body.  A tubular inserter with appropriate grips and a cervical abutment flange is used to receive the IUD in elongated deformation.  The device is slipped through the tubular inserter by a plunger and as the IUD emerges from the upper end of the tube, strain on one of the lines caused by abutment of the bead on the lower end of the tube positively bows and pulls the emerging IUD into a sub-stantially circular configuration within the plane of the fundal cavity, the inserter having been appropriately oriented during the preliminary insertion steps.

In the first cell, a two-compartment cell in which the compartments are separated by a permselective membrane of a hydrolyzed copolymer of a per-fluorinated hydrocarbon and a fluorosulfonated perfluorovinyl ether or of a sulfostyrenated perfluorinated ethylene propylene polymer, the sodium chloride solution is electrolyzed at a pH of about 4 to 7 to produce aqueous sodium hydroxide solution in the cathode compartment and chlorine and cell liquor containing chlorate in the anode compartment.  Then, the cell liquor, already containing some chlorate, is further electrolyzed in a conventional chlorate cell or equivalent apparatus to convert chloride therein to chlorate.  After separation of the chlorate from chloride present with it the chloride is returned to the first cell.

Abstract: ABSTRACT OF THE DISCLOSURE      A rotary drum assembly includes separate agglomerating and hardening drums that are rotated independently of each other. The agglomerating drum has a generally cylindrical configuration with an inner cylindrical wall.  A scraper is rotatably position-ed within the agglomerating drum in spaced relation to the inner cylindrical wall with its axis spaced from the axis of the drum. The scraper has a tubular body portion with a plurality of para-llel rows of blades extending radially therefrom.  Each of the rows extends lengthwise along substantially the entire length of the scraper body portion and follows a helical path having a single turn about the axis of the tubular body portion.  The rows of blades thus make a single convolution about the scraper body portion.  Drive means are provided to synchronously rotate the agglomerating drum and scrapper with the scraper arranged to rotate at a preselected and different speed relative to the speed of the drum.  Agglomerative material is introduced into the rotating agglomerating drum and forms a layer of agglomerative material on the drum inner cylindrical wall.  The scrapper is ro-tated in the same direction as the direction of rotation of the agglomerating drum and at a preselected synchronous speed with the agglomerating drum and at a reselected synchronous speed with the agglomerating drum.  The rows of parallel blades on the scraper form a plurality of spaced, elongated, generally longitu-dinal ridges and valleys in the layer of agglomerative material on the drum cylindrical wall.  The ridges have a slight arcuate configuration and form less than a single convolution throughout the entire length of the agglomerating drum.  The spaced, elon-gated ridges in the layer of agglomerative material extend length-wise in the drum substantially parallel to the axis of the drum and serve as longitudinally extending lifters to mix and agitate other particulate agglomerative materials introduced into the drum by lifting portions of the other particulate agglomerative material from the underside of the bed and depositing the material on the upper surface of the bed.  This type of mixing promotes the formation of agglomerates having a preselected, relatively narrow size range.  The synchronous rotation of the scraper removes agglomerative material deposited on the surface of the elongated ridges and valleys formed in the layer of agglomerative material so that the desired ridge and valley con-figuration is maintained in the layer of agglomerative material.

Abstract: AIR CLASSIFIER                        Abstract An air classifier for the separation of refuse by density into homogeneous fractions.  A waste bin discharges non-homogeneous waste which is dispersed within a mixing chamber whereat a pressurized airflow, moving upwardly therethrough, carries lighter particles upwardly into a main duct structure.  Subjacent the mixing chamber, is a crossflow zone through which a secondary airflow moves transversely to waste gravitating from the mixing chamber.      The classifier main air duct is of irregular shape having enlarged portions, spaced therealong, each constituting a waste separating station whereat waste particles of like density gravitate into a discharge chute.  Air inlet means at each separating station directs a crossflow of air past the gravitating waste matter to remove lighter density particles and return same back to the main duct airflow.      The crossflow of air additionally serves to pick up particles from an inclined surface of the main duct and return the particles to the main duct airflow while preventing un-desired vortex formation.  An auger housing, below each waste separation station, further classifies waste separated at that station by physical size of the waste particles.
