Title: Pressure cooker
Inventor: VON DER BECKE REINHARD
IPC: A47J27/08
Filed: 1983-10-11
Granted: 1987-08-13
Abstract: The invention relates to a steam pressure cooker, which essentially consists of a lower pot and a cover unit sealing the lower pot. The lower pot has a smooth circular pot rim. The cover unit consists of a lower lid and an upper lid. The latter is designed as a sealing element, which engages the lower part of the pot rim by the flanges. As an improvement of this type of pressure cooker, it is proposed that the upper lid contain two half-lids, and that each half-lid be able to rotate about its own axis of rotation essentially parallel to the central axis of the pot (geometrically vertical) relative to the lower lid and lower pot, and further, that the axes of rotation lie eccentric to the pot's central axis and diametrically opposite each other with respect to this axis swivel mechanism rotatably supported concentrically on the lower lid.

Title: Method and apparatus for curtain coating
Inventor: DEGRAUWE DIRK MICHEL
IPC: G03C1/91
Filed: 1984-10-05
Granted: 1988-02-11
Abstract: Flexible web is conveyed over a web supporting roller while a free falling curtain of coating compsn. is formed of a width greater than the web width and the width being maintained by side edge guides in wetting contact with the curtain. The curtain is maintained so it falls on the web at a zone where the web is supported on the roller and edge portions of the curtain are intercepted and redirected to leave the marginal edges of the web uncoated. The web supporting roller is of less length than the width of the web and the interception occurs in the immediate vicinity of the upper face of the web by devices which are located so the marginal portions of the web are slightly downwardly displaced against elastic recovery forces induced in the web.

Title: Method and apparatus for monitoring automated testing of electronic circuits

IPC: G11C7/22

Granted: 1988-05-05
Abstract: A timing subsystem 10 including several test period generators for supplying a variety of timing signals to a device under test. Major, minor, and free-run period generators each supply various timing signals to a multiplexer 18, which selectively connects the timing signals to timing generators 20. A central processing unit 28 supplies data to the period generators and timing generators to define their respective timing signals. Timing signals generated by the major period generator 12 define the overall testing rate. The minor period generator 14 generates multiple timing signals within the periods of the major clock signals to permit higher clock rates. Timing signals that are independent of the major clock periods are generated by the free-run period generator 16. An external synchronizer circuit 26 provides a feedback loop from the device under test 22 to the major period generator. A reference driver trigger delay circuit 27 provides means for calibrating the timing generators. Each of the three period generators includes two interconnected timing interval generators 30 and 40 that alternately generate overlapping timing signals. Each timing interval generator includes a stop-restart oscillator 32, a counter 34, and a delay-line vernier 36. Upon the receipt of a start signal, the oscillator stops and restarts to align its clock pulses to the start signal. The oscillator output clocks the counter, which supplies a signal to the vernier when a preselected number is reached. The vernier delays the counter signal by a preselected delay and issus a signal that designates the end of the period.

Abstract: 0 The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at (52). The arms (39, 41) are biased downwardly by wire springs (67) to expose the typing line. Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing point. The terminal members (59) slide on guides (62) at the ends of the side arms (33, 34), constraining the external ribbon run to lie always within and translate within a single plane. The edges of the guides (62) are curged so that the tilt of the terminal members (59) varies as they move up and down, in such a way as to maintain the ribbon tension uniform across the width of the ribbon (17). The arms (39, 41) are flexible and have pivotal play to permit these constraints on the terminal members (59).

Abstract: A process is disclosed for the continuous removal of ammonia from wastewater which converts the otherwise undesirable ammonia to a commercially useful end product such as ammonium phosphate. The process is carried out in an Advanced Separation Device which comprises a plurality of chambers moving about a circular path in periodic fluid communication with a plurality of fixed feed and discharge ports. The chambers are filled with a zeolite adsorbent which effectively adsorbs the ammonium ions contained in the wastewater at low pH levels but which, when contacted with an alkaline regeneration solution, releases the previously adsorbed ammonium in the form of ammonia gas, for which the zeolite has no affinity. By virtue of the ASD design, it is possible to add acidic materials to the wastewater in an intra-stage fashion i.e. during the adsorption step so as to optimize process efficiency. Similarly, intra-stage addition of alkaline materials during the regeneration step results in increased process efficiency. The process may be practiced with both industrial and municipal wastewaters.

Abstract: An improved method and apparatus for the continuous vacuum grinding of meat or other products is provided which permits continuous deaeration and grinding so as to materi. ally enhance the organoleptic properties of final meat products such as sausages and the like. Broadly speaking, the apparatus of the invention includes a pumping apparatus(12) together with a grinder (14) and a closed conduit (16) coupling the pump and grinder; deaeration apparatus is also provided which serves to deaerate the meat products prior to grinding, and the latter are maintained in that condition throughout the grinding operation. In preferred forms, use is made of a reciprocating piston-type pump together with remote, separately powered grinding apparatus. In this form of the invention, deaeration is accomplished by means of apertured pistons (34) within the pumping unit which are operatively coupled to a vacuum pump (38) or other suitable evacuating device.

Abstract: Chemical reactions are carried out in apparatus which subjects the material to substantially even shear. The apparatus (30) passes the material repeatedly at an angle through a shear zone formed within the bulk of the reactants by relative movement of parts (1, 2) defining surfaces betweeen which the material passes. The shear zone is formed within the material by temporarily entraining material in close-ended cavities (3,4) in the surfaces so that a velocity component of the material is altered by relative movement of the surfaces during entrainment. The process is of particular value for the manufacture of detergents.

Abstract: In a magnetic resonance imaging system, the same reference signal is used for both radio frequency transmission and phase sensitive detection. The use of the same reference signal for both transmission and reception prevents phase unlock between the two events. However, this technique results in variation in the demodulated, frequency encoded information, which is corrected by digitally filtering the received signal information as a function of the demodulation frequency used.

Abstract: A method and apparatus for modifying corneal refractive properties includes a laser source, computer control, and a plurality of deflectors including at least one rotating and translating deflector. A beam emitted from the laser source is deflected by the rotating and translating deflector in a controlled manner such that the beam strikes the cornea tangentially, ablating or lathing the contacted surface. The apparatus is computer controlled to intra-operatively determine the visual axis, monitor fixation, monitor changing refractive error, adjust the rotating and translating deflector and activate and deactivate the laser. The invention allows the radius of curvature of the cornea to be modified in vivo or in vitro. The cornea is lathed tangentially in either a natural or frozen state in an area centered about its optical axis, encompassing its optical zone. In one embodiment, a rotating arm, rotating in a plane perpendicular to the optical axis of the cornea, transmits the laser beam to the variable deflector.
