Patent CA-2058697-A1 (CA)
Inventor: GUHLE ARNOLD
IPC: A61D9/02
Filed: 1992-01-02
Abstract: A method of and apparatus for treating uterine prolapses in livestock.   Firstly, clean and manually reposition the uterine prolapse. Secondly, insert an internal uterine support through a cervix and deep into a uterus of an animal thereby supporting the positioning of the uterus.  Thirdly, block the removal of the internal uterine support for sufficient time to permit the cervix of the animal to contract.   Fourthly, withdraw the internal uterine support once the cervix of the animal has  contracted.   The  apparatus  has  an inflatable supporting member serving as the internal uterine support. The supporting member is positioned on an elongate member which is insertable through a cervix and into a uterus of the animal. When expanded the supporting member is of a size sufficient to provide  internal uterine  support and when contracted the supporting member can be withdrawn through the contracted cervix without causing discomfort to the animal.

Title: Detergent containing article
Inventor: VAN DEN BROM GUIDO C
IPC: C11D17/04
Filed: 1992-04-01
Abstract: A fairly constant concentration of detergent product in the wash liquor in a dishwashing machine can be obtained by using a sachet containing 20-350 grams of both detergent powder and one or more solid detergent briquettes, the weight of each briquette being in the range 1-100 grams and the total weight of the briquettes being 10-200 grams. When applying this sachet the need for extra detergent dosing in between consecutive washes to compensate for the dilution effect of rinse water is eliminated. The sachet is especially useful in industrial ware washing machines.

Patent CA-2066545-A1 (CA)
Inventor: FERNANDEZ JORGE D
IPC: H04W88/18
Filed: 1992-04-21
Abstract: A paging device sends text messages to pagers via paging services observing different communication protocols. Communication data is stored in random access memory and includes a service file identifying telephone numbers and protocols associated with each paging services and a pager file containing pager identification codes. Operator message creation and automatic transmission occur contemporaneously, coordinated with status fields in message records. Each newly-created message is stored in a queue together with control data identifying a paging service and pager and status data indicating a "pending" status, namely, a requirement for transmission of the message. The automatic transmission involves repeated scanning of the queue for pending messages, programming a modem according to the message's control data, and arranging transmission to the relevant service. The status of messages subject to transmission errors is automatically set to "rejected". The operator can retrieve any message from queue, setting its status from rejected to pending to reinitiate transmission or from pending to cancelled to suppress transmission. Communication data can also be transmitted to and received from an identical device in a remote service center, to allow correction of faulty communication data or reconfiguration to meet user requirements.

Title: Inflatable bolster for head strike protection in bulkhead seating
Inventor: BARK LINDLEY W
IPC: B64D25/00
Filed: 1993-01-07
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an inflatable bolster apparatus attached to an aircraft bulkhead which inflates if a crash sensor detects a crash.  The inflated bolster provides head strike protection for occupants seated in rows directly aft of bulkhead structures.  The uninflated bolster is folded and stowed within a frame that is attached to the bulkhead structure.  When a crash is detected, the crash sensor transmits an electrical signal which ignites the gas generator(s) and inflates the bolster.  In a preferred embodiment, the bolster comprises one of more cells that can be customized for the number of occupants it protects.  Each bolster cell contains an internal web structure with a series of holes that regulates gas circulation within the bolster, thus stabilizing the bolster apparatus.

Title: Ball delivery device
Inventor: JOURDAN LARRY
IPC: A63B69/40
Filed: 1993-01-08
Abstract: ABSTRACT OF THE DISCLOSURE The ball delivery device includes an enclosed non-transparent delivery conduit extending outwardly from a substantially vertical support structure.  The enclosed non-transparent delivery conduit includes a ball receiving portion at one end and a ball discharging portion terminating at a discharge opening at an opposite end.  The entire length of the ball delivery conduit including the ball discharge portion is enclosed and made from a non-transparent material to prevent the player from viewing the ball until it is discharged from the opening.  The delivery conduit may be pivotably connected to the support structure so that an adjustable positioning rod positioned between the support structure and the conduit can be adjusted to vary the angular position of the conduit.   The discharge portion may be formed from non-transparent rigid tubing rotatably connected to the delivery conduit to provide a simple and effective means for allowing the player to vary the speed and trajectory of each pitch or series of pitches.  Alternatively, the discharge portion may be formed of a deformable material, such as corrugated metal or plastic, which can be adjusted to an infinite number of positions corresponding to various ball trajectories.

Abstract: A suction inlet for a central vacuum system of a building includes a housing capable of being mounted on the floor of a building in a fixed position and defining a slot along the  floor.   Slot can be opened and closed and simultaneously a vacuum duct connected to the housing is opened and closed by a plug member.  When the plug and the slot are opened, an electrical switch actuates the central vacuum system to draw air into the housing through the slot across the floor so that dust, dirt and debris on the floor can simply be swept into the slot and drawn away.  The plug member can be moved to the open position by a foot operated lever that pivots about a pivot point on the housing.  The plug member is biased towards a closed position where it prevents  dust  and dirt  from being drawn through said housing and into said vacuum duct.

Title: Cardiac vulnerability tracking by t-wave alternans analysis
Inventor: VERRIER RICHARD L
IPC: A61B5/361
Filed: 1992-02-12
Abstract: A method for dynamic tracking of cardiac vulnerability to ventricular fibrillation is disclosed. A heart is monitored to sense an ECG signal (202) which is amplified (206) and low-pass filtered (208) before it is digitally sampled (210) and stored (212). The location of the T-wave in each R-R interval of the ECG is estimated and each T-wave is partitioned into a plurality of time divisions. The sampled ECG signal in each of the time divisions is summed together and a time series is formed for each of the time divisions such that each time series includes corresponding sums from corresponding time divisions from successive T-waves. Each time series is detrended in order to eliminate the effects of drift and DC bias, and then a method of dynamic estimation is performed on each time series to estimate the amplitude of alternation for each time division (214).
