Described are techniques to stabilize storage devices receiving signals from plural asynchronous docks, especially to avoid "metastability", in particular, a multi-dock pulse synchronizer circuit with an IN-section for receiving and storing prescribed impulses and input cock signals, and for responsively outputting intermediate signals: and an OUT-section for receiving and storing the intermediate pulses, synchronous with certain output clock signals and processing them to generate certain outpu...

It is well known that the autocorrelation function of a psuedo-random sequence, multiplied by itself delayed, theoretically consists of one peak at zero delay and approximately zero amplitude at all other delays. It is also known that, in practice, there are second order effects which give rise to secondary peaks at delays other than zero. In a system such a pseudo-randomly phase modulated radar altimeter, which utilizes the autocorrelation peak to lock on and track, the appearance of secondary ...

A pressure driven altimeter is provided with an A.C. torquer to impart low amplitude torsional oscillations to a drive shaft of the gear train between the aneroid mechanism and the output pointer. These shaft oscillations are coaxial with the direction in which this shaft is pivoted by a pressure-altitude sensing aneroid mechanism. These torsional vibrations serve to prevent buildup of static friction forces and overcome other friction forces that will interfere with altimeter accuracy and resol...

A wall-avoiding recliner chair wherein the seat and backrest move as a unit forwardly to a TV reclined position during which time the footrest is projected to extended position, and subsequently the seat and backrest may be moved relative to each other into advanced reclining positions with the footrest remaining extended. The chair is driven into TV position by the occupant moving the armrest forwardly while exerting pressure on the backrest. Subsequently, the chair is placed into advanced recl...

A method for enabling a balding person to avoid the appearance of baldness comprising the steps of locating sutures at strategic locations on the person's scalp, securing a scalp net to said sutures with said scalp net having synthetic fibres which simulate hair secured to the portions of the net which cover balding areas on the scalp. The scalp net has openings where it covers a person's natural hair which extends through said openings.

The invention provides a method of treatment of the human or animal body comprising the application of an aqueous solution containing a compound of formula I ##STR1## [wherein R.sup.1 represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms and R.sup.2 represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms or a group of formula II ##STR2## in which R.sup.1 is as defined above] to human or animal tissue subjected to surgical treatment whereby the incidence ...

A method and apparatus for preventing the vaporization of a cooling liquid used in a boiler which is heated by waste gases from a converter. A circulating pump pumps a constant amount of cooling liquid through a system which includes in addition to the boiler and the pump a heat exchanger in which the liquid is cooled after leaving the boiler and a reservoir which receives the cooled liquid from the heat exchanger and which supplies the liquid to the circulating pump. A compensating or equalizin...

A device for a mobility cane which assists in the cushioning of impact and the avoidance of obstacles. The impact cushioning component can be adapted at either end of the cane or built into any portion along the length of the cane.

A recliner chair with wall-avoiding action which permits the chair to be placed adjacent a wall without striking the wall when the chair is moved to reclining positions. The wall-avoiding action is achieved through a linkage which suspends the seat and its rigidly incorporated armrests, relative to a fixed base for swinging movement between a normal or generally upright position, and a number of reclining positions where the backrest extends rearwardly at an incline and the seat also extends at ...

A connection device for connecting two spaces, comprising two connector parts (1,11) (4,14) each having a flexible tubular member (2,12) (5,15) which members have sealing surfaces (3,13) (6,15) which on connection are brought to bear on a surface belonging to the other connector part by the first tubular member being introduced into the second connector part and inverted inside out.
