Patent CA-2064390-A1 (CA)
Inventor: BROWN MARVIN A
IPC: B01D24/24
Filed: 1992-03-30
Abstract: A cap for filter underdrain blocks is provided, wherein the cap has a porous body with a top surface, a bottom surface and downwardly extending flanges.  The cap is  installed on a filter block having a plurality of orifices  in  a  top  wall  of  the  filter  block  for channelling fluids to and from an overlying filter media. The bottom surface of the cap along with the flanges define a distribution chamber above the orifices, and the cap has a porosity such that a fine grain filter media may be placed directly on the top surface of the cap without media penetrating therethrough and clogging the underdrain blocks.   The distribution chamber enhances distribution of backwash  fluids throughout the  filter media,  and the cap eliminates the need for a separate gravel support layer to be installed between the fine grain filter media and the underdrain blocks.

IPC: B65H75/02
Filed: 1992-04-16
Abstract: The described storage device comprises at least one storage appliance with a gripper and a number of roll cores and is used for the storage of material as rolls, especially for storage of printed products in rolls. The gripper has a central element (10) which is attached to a transport appliance and which supports a gripper spider (20). Clamping arrangements (30) for clamping rolls (W) at their periphery and core carrier arrangements (40) for taking hold of individual empty roll cores (WK), or ones which have been loosely placed on top of one another, are arranged on the gripper spider (20). Roll carrier arrangements (50) which support the cores of clamped rolls can be arranged on the central element (10). The core carrier arrangements (40) are movable or pivotable in such a way that they can be moved away from the region of rolls to permit handling of the latter. The movements of the gripper parts are driven by linear drives and monitored by sensors, so that the gripper can operate fully automatically. The roll cores (WK) are essentially hollow cylinders, containing holding means (60) inside them, by which they are taken hold of by the core carrier arrangements (40) and the roll carrier arrangements (50). <IMAGE>

Patent CA-2072625-A1 (CA)
Title: Composite gas filtering unit
Inventor: LANDY KEITH
IPC: F01N3/08
Filed: 1991-10-03
Abstract: A comprehensive gas filtering unit in which the preferred embodiment includes sheet(s) of flexible, coilable, permeable, carbon impregnated fabric that are spirally wound around a center structure is disclosed. Active gas filtering spacers are optionally employed between the adjacent layers of wound fabric to physically separate same, thus creating air flow channel(s). Further, the active filtering spacers promote pneumatic agitation and pressure differentials. The air path typically is shaped to varying patterns including an outward flow perpendicular to or traversing the layers of the filtering fabric; flow through the actively filtering spacers; and parallel flow along the surfaces of the filtering fabric and the actively filtering spacers, with varying combinations of these patterns repeatedly occuring throughout the gas filtering chamber. Each spacer contains one or more of a variety of types of filtering agents with said spacers being employed in combination in the filtering unit, in order to effectively handle a diverse group of contaminant gases. In one embodiment a central manifold structure utilizes airflow infuser wings that facilitate attachment of the fabric. The airflow infuser wings form inlets to the filtering channels and provide structural support for said channels. The infuser wings are strategically positioned around a central air handling impeller wheel that forces air outward through the infuser wings and subsequently into the filtering channels.  This direct entry of the air results in minimal resistance to the airflow.

Abstract: 0125G                                           Dkt. No. 91A264 ABSTRACT OF THE DISCLOSURE      A volatile component  is  recovered  from  a  an  inert  gas blanketed  gas  source  containing  the  volatile  component,  an inert carrier gas, water vapor and oxygen as an impurity by a continuous process including the steps of adsorbing the water vapor  from the  stream,  condensing  substantially  all  of  the volatile  component   from  the  stream,   heating  the  water vapor-free and volatile component-free gas stream, purging the adsorbers with the heated gas stream and venting the purge gas and desorbed moisture.  Inert gas depleted from the source is replenished with oxygen-free inert gas, thereby minimizing the concentration of oxygen in the source.
Patent CA-2073700-A1 (CA)
Title: Source voltage control switching circuit
Inventor: KONISHI HIROFUMI
IPC: H04N5/76
Filed: 1992-07-13
Abstract: In a BS (direct broadcast by satellite) timer recording mode, a constant voltage diode for controlling 18 V is directly inserted in a power circuit.  Alternatively, a delay circuit is inserted at the input of a switching circuit for switching the constant voltage diode, thus absorbing the switching time difference between 140-V control and 18-V control.  Therefore, the secondary side output voltages can be prevented from being increased, and the output voltages can be stabilized both in the BS timer recording mode (light load powering) and in the television mode (maximum load powering).

Abstract: The interface is formed by an astable multivibrator ring type oscillator comprising an odd number of inverting components. The power supply inputs of the inverting components constitute the functional inputs of the interface. The oscillator output signal is a continuous signal as soon as one of the inputs is no longer supplied correctly and the interface has the property of being strongly fail safe with respect to all the failures which may occur within it. The interface can be used as the base component of a voting module.

Title: Process and arrangement for automatic manufacturing of articles made from plastic, particularly form recyclable plastic
Inventor: RYDMANN THEO
IPC: B29C45/77
Filed: 1992-09-09
Abstract: ABSTRACT:    This invention relates to the automating of the process for manufacturing larger articles from plastic, particularly recyclable plastic waste.  From a lengthened separator head 2 flanged to a plasticizer 1, by way of one shut-off mechanism 4 respectively, several molds 3 connected to it are supplied with melting 5.  A preprogrammed control device 10 monitors the filling of the respective mold 3 by way of a sensor 9.  When the desired filling has been reached, the shut-off mechanism 4 is closed by means of the control device 10, and another mold 3 that is ready to be filled is filled with melting 5 by the opening of the corresponding shut-off mechanism 4.  In addition, the control device 10 controls the subsequent pressing of additional melting 5 into the already filled mold 3, starts the operation of the heating and cooling device 12, causes the opening of the mold 3 and the ejection of the molding 8 as well as the subsequent closing of the mold 3, and signals its readiness to be filled to the control device 10.

Abstract: Apparatus for the physical vapour deposition of an alloy whose constituent elements have widely differing vapour pres-sures comprises an inner evaporation crucible (1) surrounded by a second evaporation crucible (2) having an array of nozzles (9) angled towards collector (5). In use of the apparatus, a charge (3) of relatively low volatility is evaporated from inner crucible (1) using an electron beam (7) focussed by magnet (8). Charge (4) in second crucible (2) is of much higher volatility and is evaporated by radiant heating. The nozzles (9) direct the vapour from charge (4) along pathways which intersect the vapour rising from charge (3) such that the combined vapour stream reaching collector (5) is an intimate mixture of constituents. The nozzles (9) may also serve to control the flow rate of vapour from the second crucible (2).
