Abstract: An aerosol spray actuator for a pressurized aerosol canister and in particular trigger or button actuated spray actuators having three main parts to simplify the mechanical moving parts of a spray actuator. An actuator button, an actuator base and finally a nozzle piece being inserted at the very end of a product dispensing passage embodied either in the body or the trigger part. A mechanism for permitting and blocking the actuation of the spray actuator is also provided so that inadvertent operation of the actuator can be prevented.

Abstract: Methods of forming mold cavities suitable for hook and loop fastening are disclosed, along with effective hook construction and hook and loop fastener products that have an ultrathin cross-section. Photochemical techniques are employed to form plates that define hook-form mold cavities, and, alternatively, chemical etching is employed following preforming of the cavities and machining. Hooks having three-dimensional tapers with enhanced loop engaging characteristics are disclosed. By utilization of special surface finishes and tolerances, hook fasteners, having ultrathin cross-sections are realized, that pave the way for practical use of touch fasteners in a wide range of new areas.

Abstract: Methods of forming mold cavities (1) suitable for hook and loop fastening (100), along with effective hook construction and hook and loop fastener products that have an ultrathin cross section (118). Photochemical techniques are employed to form plates (250) that define hook-form mold cavities (1), and, alternatively, chemical etching is employed following preforming of the cavities and machining. Included are hooks having three-dimensional tapers with enhanced loop engaging characteristics. By utilization of special surface finishes and tolerances, hook fasteners, having ultrathin cross sections (118) are realized, that pave the way for practical use of touch fasteners in a wide range of new areas.

Abstract: A method of manufacturing plates assembleable in a stack to provide a mold to form fastener elements includes applying a photoresist material to at least one side of the plate. The photoresist material is exposed to light. Portions of the photoresist material are removed based on the light exposure. Acid is applied to the plate, dissolving portions of the plate exposed to the acid and creating cavities.

Abstract: A hook-type fastener product for engaging loop elements is disclosed, having parallel rows of hooks having differently constructed first and second sides. The hooks are arranged such that, when engaged with loops, they resist disengagement from the loops more strongly when pulled in one sideways direction than when pulled in the opposite sideways direction. The product has a common base from which the hooks, which are not limited to J-type hooks, extend. The first sides of the hooks may be flat and the second sides convex. Methods and an apparatus for producing the product are also disclosed.

Abstract: An apparatus for mounting solar cells and the like on a supporting structure, the apparatus having a panel composed of an open textured, electrically non-conductive, non-woven web adapted to receive a solar cell, a plurality of mounting assemblies, each composed of a first element adapted to be affixed on the supporting structure and a second element releasably engageable therewith adapted to be attached to the panel, the mounting assemblies attached to and arranged on the supporting structure in spaced relation to each other and retaining the panel and the solar cell borne thereby in spaced relation to the supporting structure to define an air passage therebetween, and a frame secured on the marginal edges of the panel and incorporating channels for housing the electrical cables of the solar cell.
