Patent CA-2022121-A1 (CA)
Title: Apparatus and method for heating water
Inventor: AKKALA MARC W
IPC: F24H9/00
Filed: 1990-07-27
Abstract: Disclosed is an improved water heater and method of heating water retained in a storage tank having a flue passing through it.  The apparatus and method directs hot gases flowing upwardly along the flue toward the flue's wall when heat transfer between those gases and the water is desired.  The apparatus and method also directs the air or gases flowing upwardly within the flue away from the flue's  wall  when  heat  transfer  is  undesirable.    The apparatus includes a plurality of moveable flow control fins secured at various locations along the length of a baffle supported within the flue.  Each fin is secured to the baffle by a piece of bi-metallic material whose shape changes in response to its temperature.   When hot gases flow through the flue during a water heating mode, the bi-metallic pieces position the fins near the middle of the flue along the baffle's length and direct the flow of hot gases outward toward the flue's wall.  When relatively hot gases are not passing through the flue and the only gas or air flow in the flue is that associated with a pilot burner,  for  example,  the bi-metallic pieces  sense the relatively cooler gas/air flow and position the fins near the flue's wall where they obstruct flow along the wall and direct it along the central axis portion of the baffle.

Abstract: A bed with a built-in commode of this type is used for a user such paralyzed,bedridden person or the like and comprises; a mattress having a through-hole substan-tially at its central portion,a commode disposed in the through- hole of the mattress,a discharge pipe communi-cated with the commode for discharging the excrement received in the commode,and this built-in commode is further equipped with a plurality of inflatable pads which open the commode opening of the commode when they are deflated and support the user's hips when they are inflated,in addition,the discharge pipe is provided with a valve which can open or close the discharge passage of the discharge pipe.    By virtue of the aforesaid construction,the commode opening can be opend by deflating some of the inflatable pads when the user lies on the bed reclyning on a matt-ress having been erected,while these pads can be alter-nately inflated or deflated when the user lying on the bed at his rest position,so that the user can be preven-ted from having bedsores,moreover,since the discharge passage is tightly closed by the valve,any foul odor arisen from the commode will never leak and float into the room.    Moreover,the commode is rendered possible to close the valve before excretion and preventing the commode from becoming dirty by foaming bubbles in the commode, and at the same time,to seal the odor to prevent it from leaking out by forming such bubbles in the commode, and by virtue of the valve, it is also possible that the user can enjoy hip bathing by closing the valve after the excretion.

Abstract: In an automated machine tool assembly where a plurality of work stations are interconnected by slide rails on which pallets can slide, the pallets having workpieces affixed to them, with at least one transfer bar for engaging a pallet and sliding the pallet longitudinally along the slide rails, a hydraulic lift and monitoring system includes a plurality of hydraulic cylinders in the transfer bar, a plunger in each cylinder, and a first source of pressurized fluid which urges each plunger upwardly against a pallet.  The first source of pressurized fluid is adjustable so as to pre-set the pressure with which the plungers are urged upwardly.  A second source of fluid under pressure is linked through the cylindrical chambers in series to a pressure-sensitive switch such that, if a plunger fails to rise to its uppermost position when not loaded with a pallet, the operator is given a signal from the switch that a malfunction exists.

Title: Video display apparatus with kinescope spot burn protection circuit
Inventor: GURLEY THOMAS D
IPC: H04N9/64
Filed: 1991-04-04
Abstract: A television receiver includes a kinescope spot burn protection circuit comprising a capacitor coupled between a source of blanking signal and a control grid of the kinescope for applying negative grid cut-off bias to the kinescope in response to the blanking signal. The amplifier is of the cascode type having a minimum output voltage for peak white levels of a video signal applied to the cathode. The protection circuit includes a potential divider for biasing the kinescope at a positive voltage level related to the minimum output voltage of the amplifier during normal operation of the receiver to maximize the brightness of displayed images.      The protection circuit also includes a breakdown device in the potential divider for limiting the maximum grid bias voltage to a level less than the minimum output level of the amplifier but greater than the positive voltage level provided by the potential divider to thereby avoid forward biasing the grid of the kinescope upon termination of the blanking signal which otherwise could occur during recharging of the capacitor.
