Title: Means for restraining blankets from slipping off a  bed
Inventor: LEE HELENA M
IPC: A47C21/02
Filed: 1982-01-07
Granted: 1983-08-16
Abstract: ABSTRACT     Because most beds are now sold without a footboard many people find that their blankets tend to slip off the foot of the bed during the night.  Awaking feeling chilled, they have to get out of bed to retrieve the blankets, a chore particularly difficult for arthritic and elderly people.          The invention consists of a method and apparatus for preventing blankets from slipping off a bed during the night.  The method comprises fastening a length of elastic material across the foot of the bed such that the elastic material maintains pressure on the blankets.  The apparatus comprises a length of elastic material and adjustable means for holding it taut across the foot of the bed.  By preventing the blankets from falling, the invention helps the person to stay warmer, which may allow reduction of the heat in the house at night.   1.

Abstract: Abstract of the Disclosure:     For use in combination with a loudspeaker and at least one microphone, for example, by attendants in an auditorium, an echo cancelling circuit comprises a self-adaptive echo canceller responsive to a lower frequency component, such as below 1.7 kHz, of a receive-in signal for self-adaptively cancelling a corresponding component of a reverberation signal included in a send-in signal during each interval during which an audio signal reaches the circuit from a remote party.  For a higher frequency reverberation signal component, an echo suppressor or a voice switch may reduce a weaker one of two signals which are either the higher frequency send-in and receive-in signal components or a combination of a reverberation component cancelled signal with the higher frequency send-in signal component and the whole receive-in signal.  Alternatively, a less expensive echo canceller non-adaptively cancels a part of the reverberation signal in response to the receive-in signal.          The lower frequency component of the partially reverberation cancelled signal is used by the self-adaptive echo canceller as the lower frequency send-in signal component.  An acoustic output may once be reproduced by the loudspeaker in response to the receive-in signal and then converted to an electric signal for supply to the echo cancelling circuit.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure relates to promotion of data from a backing store (disk storage apparatus termed DASD) to a random access cache in a storage system such as used for swap and paging data transfers. When a sequential access bit is sent to the storage system, all data specified in a read "paging mode" command is fetched to the cache from DASD.  If such prefetched data is replaced from cache and the sequential bit is on,  a subsequent host access request for such data causes all related data not yet read to be  promoted  to  cache.   For  a  certain implementation,  a maximal amount of related data is promoted; such maximal amount is determined by cache addressing  characteristics  and  DASD  access delay boundaries.  Without the sequential bit on, only the addressed data block is promoted to cache.

Abstract: Abstract of the Disclosure A head depression type dispenser comprises a cylinder formed of an elastic material such as rubber.          The cylinder is arranged between a head and a cap, and is constructed to operate as a piston for sucking and pressurizing liquid by means of axial deformation of the cylinder upon movement of the head,  When the depressing force applied to its head is removed after the cylinder is deformed, the cylinder will return to the original shape by its own elasticity.  In addition, a sealing piece extends from the cylinder into the passage of the head, thereby closely contacting the inner wall of the passage to form a secondary valve.  The sealing piece becomes isolated from the inner wall of the passage when the hydraulic pressure in the cylinder exceeds the elasticity of the sealing piece, allowing the flow of the compressed liquid through the passage, and closely contacts the inner wall of the passage by the elasticity of the sealing piece when the hydraulic pressure becomes lower than the elasticity of the sealing piece. Since the cylinder can deform in its axial direction, it can be sufficiently deformed, thereby sufficiently pressurizing the liquid to high pressure.

Abstract: ABSTRACT          "METHOD OF MANUFACTURING CALCIUM CARBIDE FROM POWDERED                  LIME/LIMESTONE"     Calcium carbide is prepared from a powdered lime material and carbon powder.  The powdered lime material, possibly together with a reducing agent, is injected with the aid of a carrier gas into a plasma gas generated by a plasma generator.  The heated lime material, together with any reducing agent used and the energy-rich plasma gas, is then introduced into a reaction chamber substantially surrounded on all sides by a solid reducing agent in piece form.  When the lime material consists of quicklime, this is melted and reduced to liquid carbide and when the lime material consists of powdered limestone, it is burnt directly in the reaction zone to form liquid carbide.

Abstract: APPLICATION OF           KENNETH E. BEYER AND WILHELM H. HORLACHER                  TWO-STAGE SOLENOID VALVE      ABSTRACT   A two-stage solenoid valve uses a pair of stacked coaxial armatures separated by a predetermined gap which is maintained by a first spring therebetween.  A coaxial connecting rod extends between a first armature and the second armature and is attached to the first armature.  A head on the unattached end of the rod bears against a bottom surface of a recess in the second armature to limit the expansion of the first spring.  A second spring is arranged to contact the head of the rod and to extend therefrom to a plug in the end of a cylindrical housing surrounding the first and second armatures.  The first armature is provided with a fluid sealing surface on a first end for sealing an adjacent fluid port in the valve in response to the spring force exerted by the second spring.  A first and a second solenoid coil assembly are coaxially stacked to surround the cylindrical sleeve housing adjacent to respective ones of the first and second armatures.  The coils are connected in series with a center tap connection therebetween to allow either parallel or single coil energization.  A first and a second source of energizing power is used to selectively energize the first and second electromagnetic solenoid coil assemblies to control the positioning of the first and second armatures to provide a first and a second spacing of the sealing surface from the orifice during an open state of the valve to provide a first and a second flow rate, respectively, through the valve.  During a deenergized state of the valve, the second spring acts through the connecting rod and the first armature to urge the sealing surface against the orifice.
