A cylindrical glass prism with one planar entry face which refracts incident beams and with multiple exit faces perpendicular to the refracted beams which are emitted without refraction and without reduction in width. The prism can be revolved on a concave cylindrical base.

The invention relates to a multiple signal cable system having a plurality of individual plug heads formed at the free ends of the cables for connection to a corresponding number of counter-piece contacts on a unitary adapter. The present invention permits a simplified manipulation of the multiple plug heads for connection with the adapter, while also affording rearrangement of the sequence of individual plug heads in accordance with the particular adapter. The individual plug heads are connecte...

An OR logic function is provided in at least two separate circuit branches by diodes in parallel summing current at a first logic node and a first circuit branch and diodes in parallel summing current at a second logic node in a second current branch. An AND logic function is performed at a third logic node by using additional diodes connected in parallel at the third logic node so as to share current passing through the third logic node, with the logic conditions at the first and second logic n...

A multiple sorter includes several sorter units disposed in series at a paper discharge outlet of an image forming apparatus. Each of the sorter units includes a paper distributing mechanism for distributing paper to several sort bins, and a first path change-over mechanism for changing over the connection of a paper lead-in path to either a paper feeding path to the paper distributing mechanism or a paper discharging path to a non-sort bin. The sorter also includes several bypass carrying paths...

A multiple switch, particularly for switching-on, switching-off and/or switching-over of motor vehicles and the like has at least one roller-shaped contact roller with a generated contact surface liftable from and bringable in contact with at least two rectilinear contact faces located near one another. The contact roller is arranged in a springy deflectable manner in a guiding part displaceable rectilinearly transversely to an axis of the contact roller and parallel to the contact surfaces. The...

A multiple loudspeaker includes a housing and a first speaker (a woofer) supported by the housing. The first speaker includes a first diaphragm. A support for supporting a second speaker (a tweeter) is provided, and the tweeter support is supported by the housing. A portion of the support for the tweeter is spaced from the first diaphragm (the woofer diaphragm), and the tweeter is spaced from the woofer diaphragm. The tweeter support can be in the form of a protective grill or in the form of an ...

A multiple boiler has at least two separate heating systems incorporated therein. Whereas boilers with two heating supplies have been known, they have been complicated systems that require heating to occur outside a water tank. The multiple boiler has an insulated water tank with a heater to heat the water in the tank without circulating water outside the tank. At least one circulating coil is located in the tank in heat exchange relationship with water in the tank.

A multiple bag comprising a plurality of bags including a chemical containing bag charged with liquid chemical and at least one vacant bag, wherein the inner surface of the chemical containing bag is less rough than that of the vacant bag.

A multiple coil, multiple armature solenoid is disclosed. The solenoid has; multiple armatures slidably disposed on a common slip shaft, with separate coils disposed about the corresponding armatures. The conductor coils, through magnetic induction, displace the armatures through respective linear strokes along the slip shaft. By varying the stroke length of the various armatures, it is possible to use an armature that travels through a short stroke length to generate kinetic energy that is tran...

A multiple connector comprises a stack of slidably interconnected modular housing sections of insulating material each containing several electrical connectors. Each housing section has a first stop cooperating with a second stop of an adjacent section to allow relative sliding of the sections between a piled position for connection of all the connectors with complementary connectors of a washing machine programmer for example, and a stepped position defined by coaction of said first and second ...
