A memory comprises a plurality of memory cell groups of different memory cell structure, dummy cell groups of different cell structure arranged one for each or several of said memory cell groups, a means for selecting a desired memory cell and a dummy cell corresponding to the group of that memory cell, and a means for differentially sensing outputs of said selected dummy cell and said selected memory cell.

An assembly includes two members, such as gyroscope gimbals, capable of limited relative rotation, and a flat, flexible conductor strip secured to the members, the axis of the strip extending between its securing positions wholly extending towards the common axis of rotation of the members the strip axis lying in a plane with the members at their mean relative orientation, and twisting as the members rotate therefrom.

1. A rocket comprising a rear section including a motor, a forward war head section, an intermediate trajectory control section, and a rotatable connection between said control and motor sections, a gyroscope and a gas generator mounted within said control section, the generator ahead of the gyroscope, said gas generator including ignition means, a first nozzle operable to deliver a wheel-driving gas stream to the wheel of said gyroscope, and a second nozzle operable to deliver an upward thrust ...

A filter for tobacco smoke comprises a porous substrate (other than tobacco) having a deposit thereon of particles of a water-insoluble hydrophobic moisture-laden substance, the major ingredient of the substance being water, which is activated by the smoke of burning tobacco to release the moisture. The filter may be in the form of a cartridge for insertion in a cigarette or cigar holder or as a filter tip made integral with a body of divided tobacco.

A device for indicating the force applied by a tool comprises a bar arranged so as to be deflected in accordance with the force applied, a pair of spaced stops carried by the bar, a frame enclosing both stops with one end of the frame engaging one side of one stop and the opposite end of the frame extending past the other stop to define a space therebetween, and a load sensing member disposed in the latter space, whereby the deflection of the bar is converted by the two stops and the frame to a ...

An exhaust silencer provided with a catalyst. It includes an expansion chamber with a reflecting wall, and a silencer chamber. A passage joins the two chambers, and a catalyst lies in the passage, preferably on the wall of a tube which forms the passage, where it covers perforations in the tube through which the exhaust gases must pass when they flow from one chamber to the other. An auxiliary catalyst can also be provided in the expansion chamber.

The present invention relates to a regulator system including a model of the regulated process. This model is blocked when saturation occurs of a regulator controlled actuator in the regulated process, and the output signal of the model is then slaved to the feed-back measurement signal so as to allow the model to function again properly as soon as the saturation ends. The system applies to the regulating of industrial processes, in particular thermal processes.

In the illustrative embodiments of the invention described, a main gas spring unit used to raise and lower a movable leg rest member of a bed construction includes a further gas spring device axially connected end-to-end to the main gas spring unit. The addition of the gas spring device allows the leg rest member to be raised, with only a small manual effort, to a higher level than is possible with the main gas spring unit alone. Preferably the internal force exerted on the piston rod of the mai...

The invention comprises an arrangement which permits placing a timepiece o a state of minimum energy consumption for storage purposes. It includes a manual control arranged to act on an electronic circuit. When the manual control is briefly actuated the minutes hand may be set to the minute, with a longer actuation causing the hands to advance through one time zone. Should the control be actuated while the hands are in motion during time zone adjustment the hands are stopped and the timepiece is...

A beverage cooling arrangement having an inner receptacle defined by a closed end, an open end and a wall disposed between the open and closed ends. An outer encasement partially encases the inner receptacle, and the encasement is joined at the upper end to the inner receptacle along the open end thereof forming a cavity between the inner receptacle and the encasement. A layer of cellular compressible heat-insulating material is disposed within the cavity adjacent the encasement. A solid gel ref...
