The small clearance retention apparatus comprises a cylindrical rotating member, a recording or otherwise cooperating member disposed in close proximity with the cylindrical rotating member so as to maintain a small clearance, in the direction parallel to a generating line of the cylindrical rotating member, between the outer peripheral surface of the cylindrical rotating member and the recording member, and a spacer for maintaining the small clearance constant. The spacer is formed by rollers s...

An improved small-sized rocker switch with indicator is provided. The switch is constituted by a housing having at least one open end; a main contact disposed in the housing; a cover member attached to the open end of the housing; a movable lever disposed in the housing such that its one end is located in the housing while the other end is projected outwardly from the cover member; a converter provided at one end of the movable lever and adapted for opening and closing the main contact; a switch...

A one-piece folding carton having a well for receiving a plurality of plastic bottles and a pair of inner side wall panels with flaps having notches for receiving necks of the bottles.

A small electric motor having a plurality of commutator segments disposed at equal intervals in the angular positional direction on an insulating cylinder fixedly fitted to the rotating shaft of a motor rotor, and brushes for making electrical contact with the commutator segments, wherein reservoirs for holding an electrically conductive mixture are provided by boring the insulating cylinder in such a manner that the reservoirs extend to the adjoining commutator segments, the electrically conduc...

An elongated bending beam and an elongated flexure strap are supported in substantially parallel, spaced-apart relationship by end cantilever blocks one of which is secured to a scale base and the other of which mounts a food receiving platform for movement vertically with respect to the scale base. First and second pairs of matched strain sensing resistors are bonded to the opposite faces of the bending beam adjacent the opposite ends thereof and are connected electrically to form a balanced Wh...

A tuning fork-type quartz vibrator having leg members of a length of below six millimeters and a thickness/width ratio below one reveals the zero temperature coefficient at temperatures appearing within a wrist watch carried by a human body. The vibrator also has a favorable low series resonant impedance.

A D.C. motor is disclosed having a magnetic plate disposed on the upper surface of the rotor for normally urging a rotor of the motor downwards. The spacing between the magnetic plate and a cover plate of the motor is made larger than the spacing of the rotor from the cover plate to ensure that the magnetic plate will not be unduly attracted to the cover plate.

A feed channel is positioned adjacent a battery of cages particularly adapted for small animals. A metering sled is longitudinally positioned in the channel and moves with reciprocating motion therein. A feed nozzle protrudes into the channel and moves with the sled. Plow members are mounted on opposite ends of the sled for distributing new feed evenly in the channel while older feed is displaced to a section in the channel nearest the cages where it will be consumed first.

The improved small switch of this invention comprises: a housing having at least one open end; main contact contained in the housing and having at least one first movable contact element and at least one first fixed contact element; a cover member mounted on the open end of the housing; a movable operating handle whose one end is disposed within the housing and the other end extends through and projects from the cover member; an illuminator disposed at one end of the movable operating handle; a ...

A passive restraining apparatus for use in the administration to small animals of anaesthetics, intravenous fluids, and the like consisting of a housing for loosely confining the animal's body. The housing is provided with a front wall which has (1) an upper opening therein for releasably holding the animal's neck in substantially immobilized position while its head projects forwardly from the wall, and (2) at least one lower opening through which the animal's forelegs are adapted to project for...
