Patent CA-2119717-A1 (CA)
Title: Paper Saver Device
Inventor: OLIVE RAYMOND G
IPC: A47K10/38
Filed: 1994-03-23
Abstract: The invention provides an inexpensive unit for removable attachment to the spindle of a roll holder for a roll-type paper product such as toilet tissue of paper towelling.  The unit is formed from a flexible plastics material and includes a centre section having an arcuate bight portion and a pair of wall portions that converge from the arcuate portion and are joined together along the free edges thereof.  An arm extends laterally from each end of the joined free ends of the walls.  The unit is slid onto a spindle and when a roll of paper material is in turn slid onto the unit-carrying spindle the joined free ends of the walls will forcefully-engage the inner surface of the roll core. When a user pulls the free end of the paper material wound on the roll the unit of this invention will rotate with the roll until the laterally extending arms engage or abut the edges of the roll holder.   This signals the user that an appropriate length of material has been pulled from the roll and that that length may now be torn from the roll.  If more material is required the user continues to pull on the free end of the paper material, causing the arms to flex inwardly and to be drawn through the roll holder until they emerge, flex outwardly again and are then available to once more abut the edges of the roll holder, signalling that another revolution has been completed and that the pulled length may be torn from the roll.  The invention is particularly useful for people on a  fixed  income and  for people  that may  be physically challenged in their motor functions.

Title: Percutaneous cardiac pump for cardiopulmonary resuscitation
Inventor: ZADINI FILIBERTO P
IPC: A61M60/468
Filed: 1993-07-30
Abstract: 2120778 9403228 PCTABS00030 An apparatus and method for cardiac resuscitation, as shown in fig. 9, comprising an expandable member (105) placeable inside the chest cavity adjacent to heart (69) to effect pumping of the heart. Said expandable member is carried in a contracted state within the blunt tip (104) of a stem (102) which is essentially mechanically advanced through the chest wall in a controlled and largely automated fashion by a device (1) placed on the anterior chest wall (107) of the patient. Said blunt tip (104) advances by blunt dissection through the thickness of the chest wall (107), after a slight incision is made in the superficial layers of the chest wall just to win the resistance of the skin to a blunt tip, in a region of the chest wall correspondent to an area, in the inner aspect of the chest wall, anatomically designated ''sine pleura'', i.e. where the pleura is absent, and is placed into the chest cavity into a region adjacent to the heart. Said blunt tip (104) can be of such a small diameter to cause only a virtual, self-sealing hole in the chest wall upon removal of the stem. The device (1) or means for placing said expandable member (104) into the chest cavity comprises a number of other safety features to prevent that structures of the chest wall as well as intrathoracic organs are injured in any way at the time of the placement of the expandable member (105) into the chest cavity as well as at the time of the actual cardiac pumping or at any time the device is being used. Said means (1) for placement of said expandable member (105) into the chest cavity comprises means for gradual and controlled penetration through the chest wall (107), with features automatically disabling the means for advancing said stem, and automatically locking the advancing stem upon entry into the chest cavity, so to avoid injuries to the heart and to the other intrathoracic organs. Upon placement of the expandable member within the chest cavity, cardiac pumping is either accomplished, after initial expansion of the expandable member (105), by periodically displacing said expandable member (105) by appling and releasing pressure to it via a rigid stem (102) from outside the chest cavity, so to alternatally compress and decompress the heart or by alternatively inflating-deflating said expandable member in front of the heart to alternatively compress-decompress the heart against the thoracic spine. Such an apparatus provides an effective method for cardiopulmonary resuscitation comparable to open cardiac massage without the trauma, invasiveness, complication and most of all without the delay in institution associated with a thoracotomy and can be implemented by paramedics or the like in the field, i.e. in the site where the cardiac arrest has occured, within the critical time frame when effective cardiac massage can still regain life and integrity of functions.

Patent CA-2136207-A1 (CA)
Title: Pyrolytic Deposition in a Fluidized Bed
Inventor: ACCUNTIUS JAMES A
IPC: C23C16/44
Filed: 1992-06-05
Abstract: Precise control of pyrocarbon being coated upon an object in a fluidized particle bed is achieved by monitoring the pressure difference between a region above the bed and a region in the lower portion of or just below the bed. Measurement of such pressure differential has been found to be truly representative of bed size in such a coater, and bed size is recognized to be a most important factor in achieving the desired characteristics of the substance being deposited. By adjusting bed size in response to changes in the pressure difference being monitored, a substantially constant bed size is readily achieved; alternatively, the pressure difference can be caused to gradually change in accord with a predetermined program. In either instance, adjustments are effected by adding additional particles to the bed or by changing the rate at which particles are withdrawn, and precise coating characteristics, e.g. thicknesses within very close tolerances, are achievable.

Title: Battery capacity detector
Inventor: YOSHIDA TOSHIO
IPC: G01R31/367
Filed: 1995-01-30
Abstract: In a communication equipment which uses a battery as the power supply, when a controller increases the transmission power at a transmitter corresponding to a drop in the electric field intensity, the controller lowers, accompanying that operation, a reference voltage from a reference voltage source which is used for comparison with the battery voltage for the purpose of detecting a drop in the battery capacity.  Therefore, even when the battery voltage is dropped due to an increase in the transmission output, the reference voltage is also lowered correspondingly, so that there will not occur an erroneous detection of drop in the battery capacity due to the drop in the battery voltage.
