The invention relates to apparatus for measuring the area and thickness of irregular articles such as animal pelts or skins. The apparatus broadly comprises a non-reflective conveyor support for articles to be measured, a series of photo-electric cells extending across said conveyor support, light means for illuminating an article on the support from above and by reflection from the article energizing such cells as register with the article, electronic means for correlating the corresponding inc...

A building system for seismic-active areas includes a base structure and an upper structure connected to the base structure by a system of connector means which collectively provide a relatively rigid interconnection under normal conditions and a relatively flexible connection when subjected to seismic disturbances. When the building system is subjected to seismic disturbances, rigid connector members fail by buckling and other connector members flex without failing to provide the relatively fle...

In a device for setting trimming areas of an original in an original image reproduction apparatus of a flat bed scanning type wherein the original is pressed on a transparent plate by a surface of a frame pivotably supported by a bearing mechanism on a side of the transparent plate when the frame is closed relative to the transparent plate and image signals for recording reproduced images of the trimming areas of the original are obtained by photoelectrically scanning the original through the tr...

A screen for use as a movable partition for dividing an open floor area comprises a frame to which screening material attached, the frame having upright side members interconnected by transverse members. Connected with one or both of the upright members and extending therealong is a stripform extrusion which receives a number of hinge tube sections which cooperate with similar hinge tube sections provided on a like stripform extrusion on a similar screen to afford substantially coaxial hinge tub...

Described is a pack comprising a carrier material such as for example cardboard, which is coated with a thermoplastic material, for liquids, comprising a tube with a bottom and a cover which has a pouring spout, in the sealing region of which are disposed, beside sealing areas with a high adhesive force, sealing areas with a low adhesive force for the purpose of peeling the sealing areas apart. In order not to be dependent on agents which impair the sealing effect and on the disposition thereof ...

A watering system for areas for the growth of plants with the water being supplied from below with respect to the plants to be grown comprises an area for the growth of the plants which comprises a watertight backing upon which a watering mat has been placed. The watertight backing comprises a waterproof channel element sheet (3) having hollow parallel channels separated from one another by partition walls. At its face in contact with the watering mat (5) the channel element sheet is provided wi...

A data recorder, preferably of the magnetooptic type, employs a rotating record storage disk. The record storage disk has a track starting primary data storing sector circumferentially adjacent to the track starting sector or a small plurality of alternate data storing sectors which are not addressable directly by mechanisms outside of the recorder as are the primary recording sectors. Whenever a one of the primary sectors in a given track is found to be defective, then one of the alternate sect...

A game includes a game board having variously shaped target areas thereon and light-weight, variously shaped, game pieces which are placed on the game board and upon which puffs of air are directed by participants. Participants' skills are directed according to rules of the game toward causing the game pieces to jump through the air and come to rest within the target areas.

An automatic sprinkler having apparatus by which it can be programmed to uniformly distribute water over a number of different irregular patterns. A programmer has a sensor device connected thereto for manipulating both a speed control means and a nozzle in a manner whereby the speed of rotation of the nozzle means about a support base, as well as the angle of elevation of the water leaving the nozzle, is controlled in a manner to uniformly distribute water over an irregular pattern.

An electro-acoustic transducer comprising a flexible film of piezoelectric material, at least one electrode provided on one side of said film amd a plurality of electrodes provided on the other side of said film to form a piezoelectric diaphragm and said piezoelectric diaphragm is imparted with a locally differing resiliency and/or tension, is provided. By using this piezoelectric electro-acoustic transducer in a loudspeaker, it is possible to improve acoustic characteristics thereof particularl...
