Abstract: A positive pressure filter respirator includes a full face mask comprising an outer mask 1 and an inner orinasal mask 2. A filter canister 5 is screw mounted to an air inlet 4, and a centrifugal fan 6, which is driven by a battery operated motor 7, is so arranged as to draw air through the filter canister 5 into the outer mask 1. The filter life and the battery life are extended by the use of a pressure responsive means which responds to the difference in pressure between the pressure in the interior of the orinasal mask 2 and the pressure in the space 20 within the outer mask 1 and outside the orinasal mask 2. The pressure responsive means reacts immediately to the commencement of either exhalation or inhalation to disable the fan 6 on commencement of exhalation and to accelerate the fan 6 on commencement of inhalation. The pressure responsive means comprises a diaphragm 9 and an infrared proximity detector 10 mounted close to the diaphragm 9, and, as described, the pressure responsive means acts to switch off the fan 6 at the commencement of exhalation and to switch the fan 6 on at commencement of inhalation.

Abstract: An improved apparatus and method for the sequential handling of a series of flexible products includes means for delivering a series of individual flexible products to a transfer point and means positioned at the transfer point for transferring the flexible products to a delivery point. The means at the transfer point include a vacuum transfer drum having a plurality of annular grooves about the periphery thereof and means for rotating the drum. Adjacent the transfer drum is an orbital packing mechanism including a shaft positioned for orbital movement, drive means for orbiting the shaft, and a plurality of packer fingers secured to the shaft and extending into the annular grooves on the transfer drum for removing the flexible products sequentially from the transfer drum and delivering them to the delivery point. The orbital packing fingers themselves are constructed to extend across substantially the entire width of the bags as they are stripped from a transfer drum and to decelerate the bags as they are stacked against a backstop. Operation of the orbital packing fingers takes place at lower speeds to reduce inertial loading and yet maintain a high output rate. In a preferred embodiment of the invention, the packing fingers are operated at a rate of 1/X times the rate that flexible products are provided, where X is the number of delivery points per lane of flexible products provided.

Abstract: A monolithic microwave integrated circuit switch includes a series field effect transistor (16) having a source drain path in series with an inductive transmission line including plural taps. Source drain paths of plural shunt field effect transistors (18,19,20) are connected to the taps. The source drain paths of the series and shunt transistors are biased so that the series and shunt source drain paths have complementary low and high impedance states. The high impedance state is capacitive, having a value on the order of magnitude of the inductive transmission line. During a first time interval, the capacitive and inductive impedances form a matched low pass filter to supply current from a microwave source to a load (13). During a second time interval, current from the microwave source flows through the shunt field effect transistors to be decoupled from the load. The circuit is in stripline form, with source electrodes of field effect transistors including first and second arms respectively having first and second elongated parallel sides. First and second elongated edges of drain electrodes of the transistors extend parallel to the elongated sides. A gate electrode of each transistor includes first and second elongated fingers respectively extending parallel the elongated sides and edges. The first finger is between the first side and first edge; the second finger is between the second side and second edge.

Abstract: The apparatus comprises, one below the other, a metering device (3), a cleaning and screening device (4,5) in the water bath, a flushing basin (8) having a loosening device (8c), and a pressure vessel (10) which is supplied with pure sand via a passage (9). A reversible pump delivers water of low pressure through feed line (12) into the apparatus up to the level N, i.e. to the cleaning device and the flushing basin. During the blasting operation, the pump automatically delivers water at twice the quantity and adjustable pressure, the passage (9) closes and pressure is built up in the pressure vessel (10), which pressure delivers the water-sand mixture through outlet (14) to the sand-blasting unit. In this arrangement, uniform water pressure in the rest of the apparatus is ensured by the pressure-reducing valve (16). <IMAGE>

Abstract: For the purpose of forming individual layers, a free-flowing mixture of an inorganic filler powder and a polyester resin is fed to a rotating die. By selecting the speed during the formation of the layers, a greater or lesser degree of separation to match the intended purpose of the conduit part is created in the layer. Thereafter, the layer of chopped glass fibres is fed in, which can penetrate at least into the inner layer portion which has become richer in resin. Thanks to this speed-controlled filler/resin distribution in the layers, less glass is required to achieve high strengths in the layers. Use of carbon-containing fillers avoids strain corrosion.

Abstract: Apparatus and methods for encoding information characters received by a station from a transmission medium to generate internal code points for retrieval or retransmission by the station. The encoding provides an internal symbol set that is able to pass complete line state information via its internal code points, thereby eliminating the need for extra signals to indicate the current line state. The code points can also report error situations, such as elasticity buffer errors, and can be accepted by the station's transmitter to be encoded and, after appropriate filtering, repeated onto the transmission medium. The internal code points are optimized so that the code point set minimizes the decoding logic at the receiving end, be it the station's Media Access Control function or its transmitter. Furthermore, internally, the station may make use of the internal code points to synchronize the receiver elasticity buffer.
