This is a drain formed of an elastomeric material having a series of channels spaced from each other, the channels defined by walls comprising a pair of rods connected by a web, the rods lying on two different planes.

A flat gasket for sealing off a region, especially for sealing off a region bordered by a cylinder head cap, includes an elastic material that effects the sealing function and at least one pass-through region for passing through a conductor such that the conductor can extend, in the mounted condition of the flat gasket, from outside the region to be sealed off into the interior of such region. The flat gasket also includes a shaped tongue connected to the pass through region and extending into t...

A flat display displays images on both sides is disclosed. The flat display includes a liquid crystal molecule layer disposed between two substrates, and a driving array having a plurality of switch devices disposed on one of the substrates. Images are asynchronously displayed on both sides of the flat display by controlling a rotation state of the liquid crystal molecule layer by the driving array in cooperation with a light source provided by a light source module. The light source module incl...

A flat file having a number of drawers is formed of a shell having a number of shelves therein for locating the various drawers of the flat file. The shelves are located by means of shelf support members formed of corrugated board having portions which are slotted and folded into place so as to locate the shelves.

An improved flat cable in which parallel, spaced conductors are embedded in an expanded, porous polytetrafluoroethylene insulation and then placed between layers of polytetrafluoroethylene having a higher dielectric constant than the porous insulation. The dielectric constant between conductors can be varied.

A flat motor comprises a rotor including a shaft and a plurality of coils arranged concentric with the shaft and each said coil being constituted by a winding having a predetermined diameter, the position of the end of the winding being set at a predetermined distance from the shaft, a magnet having a doughnut-like form with the inner periphery thereof spaced apart from the shaft by a distance smaller than said predetermined distance, and a connector plate provided on the rotor and extending bet...

A flat key and a process for the production thereof in which a blank is cut on a copying machine to form a shank having a head with a width at most slightly exceeding the width of the shank proper, and a separate head is formed with a slot in which the head of the shank is detachably received with wedge action between separate head and the head of the shank.

A thin battery of the Le Clanche type incorporating a multiplicity of electrically conductive layers arranged to cooperate in conjunction with electrochemical material to form a multicell battery. Continuous frametype sheet seals are thermally bonded to the periphery of each of the conductive layers to provide an insulative sealing arrangement. The outer peripheries of these frames also are heat sealed to provide a rigid, secure border seal for the battery assembly. Sheet separators are position...

A planting flat consisting of a unitary plastic body providing a multiplicity of planting cells having open upper ends adapted to receive growing medium, seeds, water, fertilizer, and the like; closed lower ends defining reservoirs for the retention of residual water and fertilizer accessible to the roots of plants grown in the cells; and aerating openings disposed above the reservoirs serving the combined purposes of supplying air to the growing medium and providing drainage of water and fertil...

A flat power transmission belt capable of transmitting power from oppositely facing driving portions, the belt including a tensile section of two oppositely twisted cords spiralled side-by-side and embedded cross-cords or other reinforcement disposed to have a force resolution at an angle opposite that of the lead of the spiralled cords.
