Title: Gas fire heating unit
Inventor: SLAW WILLIAM S
IPC: F24B7/00
Filed: 1988-01-18
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE     A gas fire space heater which can be an insert for an existing fireplace or a free standing unit is described.  The device consists of a gas burner with radiants disposed within a housing.  The products of combustion are collected in a first plenum, directed through a concertina heat exchanger into a second plenum, and from the second plenum up a flue.  Air to be heated is collected by a blower and circulated countercurrently to the products of combustion through the heat exchanger, around the housing, and into the space to be heated.  Air to be heated is supplied to the blower from an outside vent, and an inside vent.  The outside vent is controlled by a one-way suction damper and the inside vent is controlled by a manual damper.  The two vents form a T at the fan inlet and control of the manual damper then controls the amount outside and inside air supplied to the blower.  A thermostatic control is provided in the flue to ensure that the blower is shut off if the flue temperature drops below a predetermined temperature whereby the flue may no longer draw.          The preferred blower capacity is 200 cubic feet per minute, and the concertina heat exchanger is about three and one half inches by sixteen inches by sixteen inches.

Title: Cardiac valve prosthesis
Inventor: KNOCH MARTIN
IPC: A61F2/24
Filed: 1988-01-20
Granted: 1992-03-10
Abstract: ABSTRACT                 Cardiac Valve Prothesis It is a disadvantage of the known monocuspid valve prostheses  that, in  completely  open  position,  for generating a sufficient opening moment, the flow must be diviated unilaterally with a resultant change of direction  of  the  momentum  flux.  As  a  consequence thereof, pressure losses are high and the deadwater area in the aorta ascendens is extensive. The flow is intensively   vortexed   and   subjected   to   strong fluctuations also in the main flowing phase. In the upper  zone  of  the  aortic  sinus,  a  significant stagnation point is formed.            Said  disadvantages  are  avoided  in  the  instant invention by an S-shaped curve of the closing body (12) in the skeleton line. The inlet area (17) and the outlet area (16) are oriented towards the flow, while the opening  force  is  exclusively effective  in the central  region  behind  the swivel  axis  (13).  The S-shaped geometry favor  the formation of a stable, closed vortex on the suction side of the closing body with a resultant contribution to less deadwater in the aorta ascendens (22) and to a more favorable closing behaviour. The aortic wall is less stressed and the aorta ascendens is better washed out. According to the invention,  the  pressure  loss  in  the  area  of  the opening angle is relatively low. Due to the geometry of the closing body, a very short swivel time and a low reflux volume upon closing are favored.     (Fig. 1)

Granted: 1991-12-17
Abstract: Abstract A gear coupled, counter-rotating vibratory assembly is described for producing a fine tuned accurate linear vibratory motion without any twisting force component. The assembly has two parallel shafts that extend through a gear casing with cantilevered ends extending outward from both sides of casing. Large intermeshing gears are mounted on the shafts to rotate the shafts in counter-rotating synchronized motion. One of the gears has metal teeth and the other gear has plastic teeth.          Identical eccentric weights are mounted on the cantilevered shaft ends outside of the gear casing at the same angular positions to generate the linear vibratory motion. The eccentric weights on the drive shaft are offset inward of the weights on the driven shaft. The radius of each of the eccentric weights is greater than the radius of the gear but less than the diameter of the gears.

Granted: 1993-08-10
Abstract: Abstract of the Disclosure The carton is comprised of a corrugated paperboard tray and a corrugated paperboard cover.  The tray has upstanding side wall panels and upstanding end wall panels, the upstanding end wall panels having hand holes for lifting the tray.  The cover has a top panel provided with a non-slip surface, trapezoidally configured side wall panels and trapezoidally configured end wall panels.  Each of the side wall panels and the end wall panels of the cover are hingedly connected to the top panel by reason of weakened fold lines.  The corrugations of the cover extend at right angles to the fold lines for the cover's end wall panels so as to provide a greater degree of deflective resistance to the cover's end wall panels then that imparted to the cover's side wall panels with the consequence that the end wall panels of the cover exert a greater amount of pressure against the end wall panels of the tray than that exerted by the cover's side wall panels.  However, the end wall panels of the cover are dimensioned so as to fit within the side wall panels of the cover and thus exert a pressural action against the side wall panels of the cover, thereby increasing the amount of frictional retention force of the side wall panels of the cover against the side wall panels of the tray than would otherwise occur.  A paper mat or doily has a non-slip upper surface.  Containers can be dimensioned so as to engage both non-slip surfaces.     PA.1-7
