Filed: 1981-03-23
Abstract: This invention discloses a rolling cone drilling bit (10) having a plurality of cutters (16) which have inserted therein hard metal cutting elements (22) preferably formed of tungsten carbide alloy; and in which bit the rolling cone cutters (16) are located in such a manner that their rotational axes (32) are greatly offset from the rotational axis (34) of the drill bit. In addition, a fluid jetting system is provided in the invention that directs a pressurized fluid spray (46) across the main cutting inserts and against the formation face so that when the drill bit (10) is used in its most advantageous areas, such as the soft, medium-soft and plastic formations, the jetting system prevents "balling up» of the cutters (16) and greatly increases the drilling efficiency of the bit.

Abstract: The process is carried out in an installation equipped with separate inputs for solids and liquids, in which the liquid is supplied via a filter to a waste liquid vessel, and the dried solids are supplied to a solids vessel. Installations of this type are to be used, in particular, in hospitals and university clinics. The reduction in volume is of special economic importance in view of the cost of intermediate or final storage of this waste, which depends essentially on the volume. The essential aim of the invention is to specify a process permitting a particularly compact construction of such an installation. It is provided that the solids are led to a crusher, and after passing through the latter the already dry material is separated from the process and fed to the solids vessel, while the damp material is dried in a purging and drying system and then likewise fed to the solids vessel. The dampness discharged with the hot air is condensed, and the condensate is led to the waste liquid vessel. The material fed to the solids vessel is compacted by a pressing device, preferably in conjunction with the addition of a bonding agent. By separating the crushed and already dried solids from the crushed damp solids, it is possible for the installation as such to have substantially smaller dimensions, since it need not account for the entire volume of the solids for the rest of the passage. <IMAGE>

Abstract: This disclosure relates to a tamper indicating ring (28) for a closure assembly (24, 62) for containers, particularly glassware containers, wherein the closures (26, 28) may be readily removed even when the product is vacuum packed by the deformation of the cup-shaped body (32) of the closure and the sealing ring (44) through the application of a diametrically opposite squeezing pressure. Normally the deformation of the closure body is prevented by the removable tamper indicating ring (28) which interlocks with the skirt (36) of the closure body and which must be ruptured to effect the removal thereof. The closure may assume various configurations depending upon whether the container is to be reclosed and whether there is an internal vacuum. The closure construction permits a modified sealing surface finish (66) on the glassware container.

IPC: G10H7/00

Abstract: There is described an electronic transfer organ for precisely duplicating twenty-six known properties of pipe organ sound. The instrument employs identical circuitry throughout, for individualized generation, keying, and decoupling or discriminating of each note. When keyboard keys (01, 02, 03) are depressed, individualized note forming information is selectively transferred from programmed memories (17, 20, 39) for each voice to temporary memories in small numbers of identical tone circuits (15, 18, 21, 23, 27, 30 and 32; 16, 19, 22, 24, 28, 31, and 33). The transferred information causes the tone circuits to individually generate, switch, and decouple each note. Envelope-generating elements in components (15,18, 21, 27, and 30; 16, 19, 22, 28, and 31) preserve smooth individual keying of all notes at their characteristic speeds and distinctive patterns. Dynamic keyers in (12 and 13) duplicate the keying effects of tracker pipe organs. All tone frequencies, derived ultimately from at least one high frequency source are randomly independent in phase, and remain permanently in various degrees of optimal mistune which characterize organ pipes in good tune. A two-dimensional stereophonic system (601, 602, 603, 604) implements the individual effects of tone frequency decoupling, to duplicate the collective sound of organ pipes distributed in various arrays outside and inside organ cases. Overall construction is modular, or divisional, by keyboard and associated elements. Adapted means from the prior art enable the instrument to couple its keyboard, and to duplicate the effects of moderate musical fluctuations in the sounds of individual pipes, vibrato, and the effects of expression controls, and reverberative milieux.

Abstract: A polycrystalline silicon layer is used to allow simultaneous fabrication of both N- and P-type MOSFET's on a common channel layer during integrated circuit fabrication. The polysilicon layer is between 20A and 750A thick, and preferably between 200A and 500A thick. These dimensions afford the polysilicon layer the high effective mobility, low threshold voltage and low leakage current characteristics, especially if the vapor-deposited polysilicon layer is annealed and/or ion implanted with Si +  or Ge +  after deposition. Application of the polysilicon layer over adjoining insulating and P-type semiconducting areas allows the single polysilicon layer to serve as active terminals and channels of both conductivity types of MOS transistors without intervening insulating or semiconducting layers. Deposition of the polysilicon layer in direct contact with a single-crystal substrate enhances the beneficial electrical properties of the polysilicon layer, especially if the polysilicon layer is annealed following deposition.
