| 4118793 | Gradientless propulsion of magnetic bubble domains using modulated in-plane fields Magnetic bubble domains are propagated in a magnetic medium in a desired direction using in-plane magnetic fields which are time varying but which have no spatial gradients. In applications such as information storage, the need for conventional propagatio... | 10/03/1978 |
| 4118794 | Memory array with larger memory capacitors at row ends A memory cell of a dynamic storage device is composed of a MOSFET and a capacitor. On a single semiconductor substrate, a plurality of such memory cells are regularly arranged so as to form a plurality of columns, with the result that they constitute a me... | 10/03/1978 |
| 4118795 | Two-phase CCD regenerator - I/O circuits Insulated gate field effect transistor charge regenerator amplifiers respectively cross-couple the output regions of a pair of two-phase CCD structures with the input regions of those structures. Each amplifier senses the level of binary data charge packe... | 10/03/1978 |
| 4118796 | Device for producing acoustic vibration in flowing liquid or gaseous medium A device for producing acoustic vibration in a flowing liquid or gaseous medium, whereby a liquid or gaseous medium is continuously circulated and periodically subjected to local compression which is converted into mechanical oscillation and the medium pr... | 10/03/1978 |
| 4118797 | Ultrasonic emulsifier and method Liquids which are normally immiscible and which are to be emulsified are simultaneously directed through a chamber containing a source of vibratory energy. One of said liquids may contain suspended solid particles. The particles when present are comminute... | 10/03/1978 |
| 4118798 | Method of mixing fertilizer A mixing method particularly usable for fertilizers, comprising placing layers of material in a sectional storage bin having an auger conveyor for conveying material therefrom, emptying the compartments serially thus causing a primary mixing, moving the f... | 10/03/1978 |
| 4118799 | Apparatus for transferring metered quantities of material from one location to another Apparatus is provided for moving controlled quantities of a material from one location to another and increasing the pressure thereof. The apparatus includes at least two cylinders having rams reciprocable therein. The rams are driven by a rocker arm whic... | 10/03/1978 |
| 4118800 | Device for use in beating or refining machines Sealing device for preventing leakage of pressurized medium from the housing of a defibrator, refiner and the like, in which lignocellulosic pulp material is ground between two grinding discs, one of which is mounted on a drive shaft to rotate relative to... | 10/03/1978 |
| 4118801 | Rack for vessels and means for agitating the vessels in the rack A rack is provided for holding at least one vessel so that the vessel can be agitated by a drive means. The rack comprises means for resiliently clamping the vessel, the clamping means permitting the vessel to move with the clamping means defining the nul... | 10/03/1978 |
