Patent number: 8104499Abstract: A septic field dosing system is described which utilizes a self starting true siphon to deliver a dose of septic tank effluent into a conventional septic field. The precision siphon unit not only eliminates the need for electrical services to the septic tank, thereby eliminating the need for pumps and solenoid operated valves and switches at the septic tank, but also contains the effluent handling equipment in a small unit. For example, the drawdown of the septic tank is used to entirely control the operation of the dosing siphon. Further, the dimensional configuration of the precision siphon operates within the boundaries of the draw down to deliver a proper size dose to the septic field. While a typical septic tank can hold of the order of a thousand or more gallons, the precision siphon can easily fit into a five gallon bucket.Type: GrantFiled: March 28, 2008Date of Patent: January 31, 2012Inventor: Abdul Rashid

Patent number: 5770224Abstract: A controlled release capsule comprises a male plug (2) formed of a water swellable hydrogel which is engaged within a neck portion (4) of a female body (6). The capsule contains a pharmaceutically active material. In contact with an aqueous medium, such as in the gastrointestinal tract, the hydrogel plug swells and becomes disengaged from the body, thereby releasing the active material. In order to facilitate insertion of the male plug into the neck of the body, the body has a flared mouth portion (14) which is wider than the neck. The neck itself may be wider or narrower than the remainder of the body. A water-soluble cap (8) has detentes (18) which clip over the flared mouth portion so as to lock the cap thereto.Type: GrantFiled: June 26, 1995Date of Patent: June 23, 1998Assignee: R. P.

Patent number: 5763725Abstract: An improved process for the production of ethylene by non-catalytic oxidative cracking of ethane or ethane rich C.sub.2 -C.sub.4 paraffins with high conversion, selectivity and productivity, operating in a most energy efficient and safe manner requiring little or no external energy, in an empty tubular reactor, wherein the exothermic oxidative conversion of ethane or ethane rich C.sub.2 -C.sub.4 paraffins is coupled with the endothermic hydrocarbon cracking reactions by carrying out both the exothermic and endothermic reactions simultaneously in the reactor so that the heat produced in the exothermic reactions is used instantly in the endothermic reactions and thereby making the overall process mildly exothermic, near thermo-neutral or mildly endothermic, which comprises passing a preheated gaseous feed comprising of ethane or ethane rich C.sub.2 -C.sub.4 paraffins, oxygen and steam through an empty tubular reactor operated at the effective temperature, pressure, space velocity and hydrocarbon/O.sub.Type: GrantFiled: September 18, 1997Date of Patent: June 9, 1998Assignee: Council of Scientific & Industrial ResearchInventors: Vasant Ramchandra Choudhary, Amarjeet Munshiram Rajput, Shafeek Abdul Rashid Mulla

Patent number: 5750143Abstract: A controlled release capsule comprises a male plug (2) formed of a water-swellable hydrogel which is engaged with a neck portion (4) of a female body (6). The capsule is intended to deliver two dosages of pharmaceutically active material at different times. A water soluble cap (8) is fitted over mouth (14) of the body, and defines a first volume (9) containing a first unit dosage (10). A second unit dosage (12) is contained within a second volume (11) defined by the plug and the female body. When the capsule is swallowed by a patient, the cap dissolves quickly in the aqueous medium within the gastro-intestinal tract and releases the first dosage. The aqueous medium then comes into contact with the hydrogel plug which swells and becomes disengaged from the body, usually in the intestine, thereby releasing the second dosage a predetermined time after the first dosage.Type: GrantFiled: June 27, 1995Date of Patent: May 12, 1998Assignee: R.P.
