Abstract: SELF CENTERING GATE     ABSTRACT OF THE DISCLOSURE         A self-centering stock-proof gate comprises an elongate tubular member and an extension piece slideable within the tube, the extension piece carrying an embedded wire for communicating electric shock along the tubular member and along the extension piece.  The tubular member is pivotally mounted about a vertical access on a hinge structure and is held in a central closed position by a pair of chain couplings which connect to a single spring lying along the tubular member and coupled thereto.  Each of the chain couplings has an end link freely slideable along a pin which extends outwardly to a respective side of the tubular member from the hinge structure.   Thus when the gate gets beyond a predetermined open angle, the chain slides along the pin towards the hinge structure thus reducing the mechanical advantage of the spring.

Patent CA-1339899-C (CA)
Inventor: ELTZ HANS-ULRICH VON DER
IPC: D06B3/28
Filed: 1988-07-20
Granted: 1998-06-09
Abstract: In the course of the isothermal wet treatment of textile material in rope form in jet dyeing units, the introduction of dissolved or dispersed treating agents to the fabric-recirculating gas stream on the pressure side of the blower still falls short of the optimum of efficient processing because this way of introducing the treating agent requires the presence of a specific injection cycle. By omitting the separate injection cycle and metering the treating agent into the driving gas stream at a point upstream (on the aspiration side) of the blower responsible for circulating the fabric, the invention realizes appreciable hardware simplifications which have beneficial effects not only technically but also in terms of energy comsumption, costs and ecological aspects.

Abstract: ABSTRACT           A reverse flow post-mixer attachment for direct-fixed asphaltic concrete mixers includes a modified discharge box for the downstream end of the drum and an enclosure for the down-stream portion of the drum forming a passage along the exterior of the drum.   If the smoke point of the liquid asphalt to be added to the material in the drum meets an established standard it is injected into the material upstream of the downstream end of the drum and discharged from the latter end in the normal manner.   If the smoke point of the asphalt does not meet the standard,  the material exiting the drum is  diverted into the passage along the exterior of the drum and the asphalt added there out of the burner stream in the drum.  The material and asphalt are then mixed and moved through the passage and finally discharged.

Abstract: A method of producing higher alcohols by the hydroformylation in an oxonation reactor of C4-C16 olefins in which the olefins are hydroformylated to produce an oxonation product primarily comprised of aldehydes, alcohols and formate esters.  The product of oxonation is then hydrogenated to provide a product mixture comprising higher alcohols, a high boiling fraction and a low boiling fraction.  The high boiling fraction and the low boiling fraction are subjected to distillation.  The high boiling fraction (heavy oxo fraction) is subjected to cracking (HOF cracking) in which Irreversible products comprising ether-aldehydes and ether-alcohols are cracked to aldehydes and alcohols which are distilled overhead.  The Reversible products comprising unsaturated and hydrogenated ethers which are not converted remain in the cracking reactor as bottoms product (U-HOF).  Such (U-HOF) bottoms product comprises ether and ether-alcohol dimers and acetal trimers.  The improvement in the method consists of the steps of (1) distilling the U-HOF bottoms product to recover the ether-alcohol dimers and (2) recirculating the ether-alcohol dimers to the oxonation reactor thereby converting the ether-alcohols to ether-aldehydes.
