Title: Curved rubber belt conveyor with decentralized drive
Inventor: KETTERER JAN
IPC: B65G15/60
Filed: 1992-02-06
Granted: 1995-10-23
Abstract: A conveyor belt for endless conveyor belt systems is laid in tight curve radii because the belt and the guide bar, which is attached to the underside of the belt, consist of highly elastic rubber. The belt is reinforced by preferably diagonally placed fabric inserts and can be pre-stretched in the longitudinal direction by means of a traction beam attached only at individual points so that it can do an optimum job in performing its transport function. The reversing rollers and the roller blocks are divided or are made up of individual units in order not to influence the guide bar, which runs in the middle, during the overrun. In this way, the necessary drive forces can attack at many corresponding places depending on the curve radius, without the conveyor as a whole, with a length of 100 meters and more, being subject to the so-called flip-arc effect. Instead, the curvilinear, decentrally powered conveyor belt is driven uniformly and is fed simultaneously, while one can achieve a high conveyor output also in the transfer area by means of corresponding troughing.

Abstract: يتعلق الاختراع بعملية إنتاج كيتون (MIBK) والحصول عليه بضغط منخفض بخطوة أحادية في الطور الغازي. وتستخدم عملية الضغط المنخفض بخطوة أحادية في الطور الغازي لتصنيع كيتون MIBK من الهيدروجين والأسيتون باستخدام كروميت الزنك النانوي البلوري/ البلاديوم النانوي Pd/nano-ZnCr2O4 تحت الضغط الجوي كمثال على ذلك. وتم تصميم هذه العملية لاسترداد الحرارة الإضافية المصاحبة لمخلفات المفاعل عن طريق تسخين لقيم الأسيتون وإعادة تدوير (الأسيتون المختلط) قبل دخوله للمفاعل. يليه إضافة ضاغط لعملية الطور الغازي لزيادة ضغط مخلفات المفاعل بنسبة طفيفة قبل تبريدها وتغذيتها للأسطوانة الضوئية. وتستخدم مخلفات المفاعل المضغوطة لإعادة تسخين لقيم الهيدروجين وإعادة تدويره (الهيدروجين المختلط) قبل دخوله للمفاعل. ويشتمل مخطط الفصل لعملية الضغط المنخفض بخطوة أحادية في الطور الغازي على عدة أعمدة تقطير تستخدم لفصل وتنقية كيتون MIBK. الشكل رقم (1).

Title: Defoaming compositions comprising organic acid ester polymers
Inventor: AMIR H MAHMOUDKHANI
Filed: 2012-09-29
Abstract: Cement compositions and processes for reducing air entrainment in a cement composition generally include mixing a hydraulic cement with a defoamer compositions including one or more organic acid ester polymers selected from an organic acid ester of polyethylene oxide polymer, an organic acid ester of polypropylene oxide polymer, and a mixture thereof. The compositions may further comprise an organic acid ester of an ethylene oxide-propylene oxide block copolymer.
