Title: Child resistant closure with protective flange and canted upper wall
Inventor: LA VANGE DONALD H
IPC: B65D55/02
Filed: 1992-12-29
Abstract: A child resistant dispensing closure (10) having a cap (12) and a spout (14) mounted thereon for rotation about a substan-tially horizontal axis. The upper surface of the spout is provided with a plurality of ribs (48, 50), each of which has a distinct ener-gy plane. Only one rib, usually, the rearmost (50), allows sufficient purchase to produce the force vector necessary to initiate rota-tion of the spout when a manual force is applied thereto. The cap includes a cylindrical skirt (18) with a frusto-conical section (16) extending upwardly therefrom.  A protective flange (66) extends upwardly about the perimeter of the upper end of the frusto-conical section to deter unauthorized access to the spout. The upper wall of said cap is canted at an acuate angle to a horizontal plane passing through the cylindrical skirt of the cap, so that the spout is further recessed within the protective flange.

Title: Modulated-structure of pzt/pt ferroelectric thin films for non-volatile random access memories
Inventor: VARSHNEY USHA
IPC: H01L21/02
Filed: 1993-03-15
Abstract: Modulated-structure polycrystalline or heteroepitaxial multilayers of PZT/PT ferroelectric thin films are deposited on a substrate, preferably by laser ablation. The laser ablation of the PZT/PT  layers onto a prepared substrate occurs while maintaining the substrate at a temperature between 380 ·C to about 650 ·C.

Patent CA-2132607-A1 (CA)
Inventor: DAVIES JOHN H
IPC: G01N33/00
Filed: 1994-09-21
Abstract: ABSTRACT OF THE DISCLOSURE               An ion mobility spectrometer for detecting substances such as narcotics and explosives, has inlets for a sample gas and a drift gas. The gas can be ambient air, bottled air, or another gas source. To ensure accuracy and prevent drifting of analyte peaks, the air is dried. A two stage dryer is provided comprising a first dryer, preferably a dryer which chills the air and removes water by condensation. This removes the bulk of the water. The second dryer includes a suitable absorbent, and reduces the water content to around 1-10 µg/L, i.e. a level which will not substantially affect the performance of the IMS apparatus. The first dryer substantially reduces the load on the second dryer, and enables an extended period of use before the absorbent material in the second dryer either needs to be replaced or regenerated. The increased stability of calibrant and analyte peak positions allows detection windows to be narrowed, resulting in significantly lower false alarm rates.
Patent CA-2133745-A1 (CA)
Inventor: COLLINS HARVEY C
IPC: E04F21/20
Filed: 1993-04-07
Abstract: A floor covering installation tool (10) for raising and lowering furniture, partitions or the like has a frame (12), a raising and lowering mechanism (14) and a lifting assembly (16). The frame (12) or the lifting assembly (16) has a portion which is positioned underneath the object to be lifted. The raising and lowering mechanism (14) is actuated to raise or lower the object to be lifted. Upon raising the lifted object to a desired height, flooring or the like is positioned underneath the lifted object. After the flooring is positioned underneath the lifted object, the raising and lowering mechanism (14) is activated to release the lifting mechanism and return it to its original position. Thus, the tool (10) is ready to be reused to lift another desired object.

Title: Shaft Furnace
Inventor: SCHELLINGERHOUT GIJSBERTUS
IPC: F27D9/00
Filed: 1994-11-10
Abstract: A shaft furnace, e.g. a blast furnace, has a bosh, a shaft and a mantle ring at the transition from the bosh to the shaft.  At both the bosh and the shaft, there is a steel jacket and a refractory lining on the inside of the steel jacket.  Cooling elements extend into the refractory lining from the steel jacket and are arranged for through-flow of cooling liquid.  To provide additional cooling at the critical transition from the bosh to the shaft adjacent the mantle ring, there is at least one transition cooling element located near the mantle ring so as to cool a region of the refractory lining of the bosh adjacent the steel jacket at the transition.  The transition cooling element has, as seen in plan view, a T-shape, with the cross-bar of the T-shape extending in the circumferential direction of the furnace.

Title: Pipelined data ordering system
Inventor: KABENJIAN GREGORY V
IPC: G06F13/16
Filed: 1993-11-24
Abstract: A data ordering system for use with personal computers having data pipelining capability is disclosed. The personal computer comprises a central processing unit (CPU) which issues data requests to one or more data exchange units, such as memory units or data Input/output units. The data ordering system comprises a finite state machine (FSM) which receives inputs indicative of data requests transmitted by a central processing unit (CPU). The inputs cause the FSM to assume different output states which are indicative of the proper order of data requests. The state outputs of the FSM are used to enable or disable the transmission of data between the data exchange units and the CPU in order to insure the proper order of data responses to the issued data requests.

Patent CA-2164038-A1 (CA)
Inventor: SCHLESSINGER MARC A
IPC: H01R25/00
Filed: 1995-11-29
Abstract: An electrical receptacle includes a nonconductive con-tact carrier that mounts a set of female electrical contacts that are configured to receive and conductively engage plural conduc-tive prongs of a male plug.  The carrier has a generally cylin-drical outer wall that is received within a generally cylindrical chamber that is defined by a nonconductive housing.  The housing mounts the carrier for rotation about a center axis that extends centrally through the chamber.  When the carrier is rotated about the center axis relative to the housing to an "on" position (that resides within a relatively wide angular range of  "on" posi-tions), housing-carried electrical contacts that extend through housing-defined passages engage carrier-carried electrical con-tacts that extend through carrier-defined passages.   When the carrier is rotated about the center axis relative to the housing to an "off" position, electrical connection is interrupted be-tween selected pairs of the housing-carried and carrier-carried contacts.  A detent preferably is interposed between the carrier and the housing for releasably retaining the rotatable carrier in its "off" position.  The rotatability of the carrier while remai-ning within its range of "on" positions permits a male electrical plug (and an appliance cord or other form of electrical wire that is attached to the plug) to be oriented as desired relative to the receptacle for such purposes as minimizing wear and tear, and/or to accommodate the positioning of furniture at locations near where the receptacle is installed.

Abstract: The supersonic distributor for the inlet stage of a turbomachine comprises an outer case (102), a hub (101), and a set of peripheral blades (103) disposed in a ring and attached to the hub (101) to provide supersonic speed fluid passages (104) between the blades (103) to transform a flow at high pressure and low speed into a supersonic flow at low pressure.  The blades (103) are disposed radially in regular manner within a fluid feed torus.  In a section developed on a line corresponding to a given radius, i.e. in a blade-to-blade plane, the blades (103) define a profile in the form of a two-dimensional half-nozzle. This profile has a rectilinear upstream portion (134), a bulge (133) defining a throat (142) for accelerating the flow to a Mach number equal to 1, the throat (142) being of section that varies with radius, and a downstream portion (135) which terminates in a region of uniform flow at a trailing edge (131) which may be truncated perpendicularly to the axis of rotation.
