Patent EP-0068792-A2 (EP)
Inventor: BOADWAY JOHN D
IPC: B04C5/181
Filed: 1982-06-22
Abstract: A special form of fiuid cyclone in which the velocity energy in the exit fluid is converted into exit pressure thus permitting the device to discharge to atmospheric pressure or a higher pressure while a vacuum may exists in the central core of the vortex. The result is achieved by use of a curved passage at the exit which starts as a coaxial space and gradually expands and turns outward to become a circular space between two disks. The removal of reject material to atmospheric pressure with a vacuum at the core may be achieved by limiting the restriction In cross-section of the bottom core such that the pressure is atmospheric and allow it to leave through a space between the end of the cone and a blunt shaped surface. The above special form of fluid cyclone operates particularly well, because of reduced energy losses, when employed in a multiple arrangement in which the tangential velocity energy of fluid entering the barrel of the individual cyclone units is created by fluid flowing at larger radius such as to create a pattern of multiple vortex flow. The vortices are in a chamber providing a common inlet to a plurality of cyclone units whith the vortices centering on the individual units. The special arrangement of fluid cyclones is in a geometry similar to that of a vortex trail with an even number of units of opposing vortex direction. The same type of arrangement; i.e. having all of the units discharge into a common chamber, leads to further energy recovery in fluid leaving the fluid cyclones.

Abstract: A circular saw blade (10,100) has a plurality of circumferentially spaced cutter teeth (14,104) projecting radially outwardly therefrom. A portion (46,122) of the periphery of the blade rises as it progresses toward the front face of a tooth to provide a depth gauge to control depth of cut. A chip clearing channel (56,60,72,74) extends radially inwardly along the body of the blade adjacent the front face of the tooth. A pocket (36.64) formed in the blade has edge margins which receive and support front and rear surfaces of a cutter tip.

Title: Apparatus for driving take-up elements for palletizable load units, particularly for storage and transport installations and the like
Inventor: MISSIO BRUNO
IPC: B23Q7/14
Filed: 1982-09-23
Abstract: A method and apparatus (1) for driving take-up elements (7) for palletizable load units (4), which are intended to effect cycles of movement each including at least a first and a second horizontal movement in opposite directions from each other, with a vertical movement in between. These movements are driven so as to follow each other without intermediate stoppages and with a continuous and substantially harmonic variation of the velocity and acceleration of the take-up elements (7). The apparatus (1) includes a linkage (10,12) interposed between the take-up elements (7) and the motor (13) for driving their horizontal movement, and cam means (24, 25) driven by the motor (13) for driving the vertical movement.

Abstract: A method is disclosed which improves, in a uniprocessor or multiprocessor system, the switching of CPU control between different system control programs SCP. An interface area PSA (42(0), 43(0)...42(n), 43(n)) for storing old and new program status words is provided in common main storage separately for each SCP and CPU. Switching from one SCP to another for any CPU is effected by changing the contents of a prefix register (21) in the respective CPU. This switching is not controllable by user instructions executed on the CPU. 
     The method enables a preferred guest SCP (such as MVS/370) to operate in a system having a particular host SCP (such as VM/370) with an efficiency that is almost the same as if the preferred guest were operating as a standalone SCP on its own dedicated system. 
     Also disclosed is apparatus for initiating the switching of CPU control between different SCPs.

Abstract: An axially displaceable rotary part (4) is latched securely in a certain axial position relative to a concentric rotary part (1) by a mechanism (10) which includes latch means (12,13) that are rotated with concentric part (1) and are displaceable radially relative to it by movements of a ring member (20) so as to engage elements (14) of the latch means with and disengage them from a latchable member (5, 6) of the axially displaceable part. At operating speeds of the system the latch means are urged to latching position by centrifugal force. Although applicable to various rotary mechanical systems, the mechanism is particularly useful as a component of heavy duty cyclical centrifugal machine (70) for latching the bottom valve member (80) of the centrifugal basket (72) in closed position during the loading and centrifuging stages of each centrifugal operating cycle.

Abstract: A field effect transistor includes a conduction channel, the charge carrier mobility of which is modulated by applying a signal voltage to gate electrodes (2, 7). Typically the conduction channel includes more than one region (10, 11) each of different charge carrier mobility and the potential applied to the gate electrodes affects the charge carrier distribution between the two regions (10,11). This eliminates the limit in the response speed of the field effect transistor which is dependent upon the channel transit time of the carriers. A mobility modulation field effect transistor thereby increases the response speed of the field effect transistor considerably.

Abstract: Electrofocusing apparatus comprises a cell having spaced electrodes and a polyion mixture for producing a pH gradient between the electrodes, characterised in that the cell has at least one inlet and a plurality of outlets placed on opposite sides of the polyion mixture such that a flowpath for liquid is provided through the cell from the inlet(s), through the polyion mixture, to the outlets, the flowpath being transverse to the electric field and to the pH gradient and the outlets being spaced along said electric field and pH gradient, the polyions being positioned and immobilised to provide and maintain a pK gradient from one electrode to the other, so that when immersed in an aqueous medium, application of an electrical field by the electrodes will cause migration of protons to give the pH gradient between the electrodes corresponding to the pK gradient, whereby when an aqueous liquid mixture of separable components is caused to flow through the apparatus it may be at least partially divided by the electric field and pH gradient into its different components which leave the apparatus by different outlets. 
     The immobilised polyions can be provided by ampholytes immobilised by reacting them with a reactive polymerisable material, applying an electric field to form a pH gradient, and polymerising the material. A cheaper alternative comprises a buffering mixture of acidic and basic ion exchange resins, the proportion of acidic to basic resins varying across the apparatus from one electrode to the other.

Abstract: A sanitary napkin. The sanitary napkin comprises a central absorbent pad and flaps extending from each longitudinal edge of the central absorbent pad. The body of each flap contains a flexible axis about which the flap can fold on itself. The sanitary napkin preferentially bends atthe line of juncture between each flap and the longitudinal edge of the central absorbent pad. When the sanitary napkin is in a panty for use, each flap bends upwardly at the lines of juncture between the flaps and the longitudinal edges of the central absorbent pad to form the base of a wall. This wall extends to the flexible axis in the body of the flap which is folded around the edge of the crotch portion of the panty. The sanitary napkin of the present invention provides effective protection to the user during the menstrual period by preventing body and clothing soiling while being comfortable to wear.
