According to the present invention there is provided a hinged structure comprising a first gear segment, a second gear segment meshing with the first gear segment, and a link pivotally connected to each gear segment, the axes of the gear segments co-inciding with the axes of the pivotal connections between the link and the gear segments.

Abstract: This invention is concerned with the pretreatment of hair on the human head, preceding shampooing the hair with anionic type hair shampoos, and with compositions for effecting such pretreatment, to obtain highly improved manageability of the hair after shampooing and with improved fullness, combability and other desired properties of the hair. The pretreatment compositions utilize readily water-soluble quaternary ammonium compounds, particularly in combination with certain agents, notably polyethylenimines and N-ethanolacetamide, and desirably together with various supplemental ingredients.

Abstract: A receptacle device useful for receiving material, comprising a container having an open end, a closure or lid detachably and pivotally mounted on the open end of the container and an operating member connected to the closure so that the closure can be raised to and from a closed position in response to operation of the operating member.

Abstract: A jacking assembly for moving a load, in steps, axially of a pipe comprises two pawl boxes having lateral platens and which are mounted at axially spaced positions on the pipe. The pawls of the boxes slope towards the pipe and exert a grip on it which allows relative movement between the boxes and the pipe to occur in one direction only. Inflatable hoses connected to a low pressure water supply are sandwiched between the platens and exert a thrust, when dilated, which increases nonlinearly with water pressure, to move whichever of the pawl boxes is carrying the load. This movement, which provides the working stroke, is followed by a recovery stroke during which the pawl box not carrying the load is moved up to the other pawl box under the action of springs or a second inflatable hose. The assembly is able to lift a heavy load with a low pressure water supply and has no moving seals. Its operation in parallel with other such assemblies is also described for house building and slip forming purposes.

Abstract: Novel phenolic cyan dye-forming couplers contain in the 2-position a p-cyanophenylureido group. These couplers are useful in photographic emulsions, elements and processes.

Abstract: A chest protector adapted for use with conventional shoulder harness to protect the solar plexus and diaphragm areas of a player in contact sports. The chest protector comprises an outer sheet of rigid, form retaining material and an inner sheet of shock absorbing material secured to said outer sheet. Shoulder harness lacing or micro-hook material can be used to secure the protector to the harness.

Abstract: An adjustable cap kit including a first band member having first and second ends with male connection means and a bottom lateral edge with slit means adjacent thereto, a second band member having first and second ends with female connectors for compatible locking engagement with the first band member, a reinforcing member with first and second ends and a plurality of generally rectangular openings spaced apart throughout the length of the reinforcing member and a brim member having a visor portion and an inner abutment edge, the inner abutment edge including a plurality of spaced apart male connection means for compatible interengagement with the first band member slits and the reinforcing member openings.

Abstract: A protective helmet for persons with severe mental or motor disabilities is disclosed.The helmet includes padded front, side, front chin and under chin pieces. Alternate embodiments include a reinforced face frame and, most importantly, a removable lightweight transparent face cover. The underchin area is also supplied with a reinforced edging or rim to fit securely against the wearer's neck to prevent the user from pulling the helmet from his head.The face covering and the securing of the helmet around the head is preferably by lacing.

Abstract: Sports goggles are formed with anterior and posterior frame sections each having a bow spaced from each other to define a slot to provide increased ventilation of space behind lens and particularly against the rearward surface of the lens for the elimination or reduction of fogging. The anterior frame section carries the lens at a position spaced farther than normal from the wearer's face and posterior frame section carries a nosebridge and temples. These goggles may be economically manufactured by molding lightweight material into a separate posterior frame section and a separate anterior frame section, then joining the two frame sections through tab and slot assembly.

Abstract: A breast prosthesis for use as a replacement in the case of a mastectomy where the chest of the wearer presents problems in providing a satisfactory support surface for a standardized prosthesis. The prosthesis includes an internal filler part which seats in the cavity so that the prosthesis assumes its normal position.

Abstract: The invention concerns a device for the removal of foul air from toilet bowls or the like. The device comprises a conduit having an inlet opening and at least one outlet opening spaced from the inlet opening. The conduit has a hook shape and is capable of hooking over the rim of the toilet bowl and under the seat so that the inlet opening is within the bowl and the outlet opening is outside the bowl. The device also includes an air treatment means within the conduit, capable of improving the quality of foul air passing through it. The device also includes a battery-operable fan capable of drawing foul air out of the bowl via the inlet opening, along the conduit, through the air treatment means and out of the outlet opening. The air treatment means, optionally together with the battery, may be provided as a replaceable pack. A securing means, e.g. in the form of a strap, may pass through the device and be of a length to fit around the bowl. A lock can be provided on the strap.

Abstract: This invention provides a valve by means of which a major portion of the suction flow of a swimming pool filtration system is channeled through an automatic cleaning device which cleans the floor and/or wall of a swimming pool, and a minor portion of the suction flow is drawn from the surface of the pool thereby to skim the surface. The valve has a main inlet opening connectable to the device, an outlet opening connectable to the filtration system and an auxiliary opening which is closed to some extent by a closure member to normally provide a restricted aperture through which the water drawn from the surface flows. The closure member is biassed closed by a spring located in a variable volume chamber which communicates with the interior of the valve between the auxiliary opening and the main inlet opening. When the restricted aperture is blocked by leaves or the like, the pressure in the chamber decreases, compressing the spring and allowing the closure member to open.

Abstract: A mattress cover for an inflatable air mattress which completely encases the air mattress. The mattress cover is constructed of a plurality of layers of material. The layer of material in direct contact with the air mattress takes the form of a soft, smooth, cushiony material so as to substantially eliminate the creation of any noise between the mattress and the cover during usage of the mattress. The top layer of the cover includes a cushiony layer of material and the side wall of the cover includes a stiffing layer of material. The exterior most layer of the cover is constructed of a decorative fabric. The cover includes an enlarged access opening to facilitate entry and removal of the mattress from the internal compartment to the cover.

Abstract: A contoured sheet is providing having slits adjacent to corners thereof to permit the person making up the bed to reach through the slit to elevate the respective corner of the bed subsequent to which he can more easily pull the contoured corner over the corner of the sheet.
