Abstract: A pulse modulating heating system provides connection to a step heating system having a main heating controller configured for connection to a heat sensor and step heating relays connected to respective step heating element and for activating, during a heating cycle, a required quantity of mechanical relays and step heating elements to generate a required amount of heat. The pulse modulating heating system has inputs, one for each step heating relay, connectable to the main heating controller for detecting the relays activated during the cycle, i.e. the required quantity of relays. The pulse modulating system, based on the required quantity of step relays detected, activates a pulse heating element for a quantity of pulses relative to a maximum quantity of pulses for the cycle that is proportional to the required quantity of step relays relative the total number of step heating relays to generate the required amount of heat.

Abstract: A hairbrush for styling hair has a brush head releasably connected to a rod rotatably mounted on a handle portion of the hairbrush and having a handle. The brush head has a plurality of spaced apart bristles for insertion between strands of the hair and gripping the strands therebetween. As the rod, and therefore the brush head are rotatable relative the handle, the brush head, with strands of hair gripped thereon, can be rotated as the handle is moved towards the head of a person whose hair is being styled, thus causing the strands of hair to be rolled around brush head, without requiring cumbersome twisting of the handle. A spring facilitates rotation in an opposite second direction and unrolling of the strands of hair off the brush head. A locking pin enables locking and unlocking of the rod and brush head to prevent and enable rotation thereof.

Abstract: A dispenser for length material comprises a first resiliently biased locking roller and a second locking roller defining a nip therebetween for the passage of length material to be dispensed, the second roller being carried on a frame which upon appropriate movement causes the second roller to move into a locking position in relation to the first locking roller to clamp the length material to prevent unreeling or return of the free end thereto once appropriate cutting of a portion of the length material has been effected.

Abstract: A musical game for facilitating learning of musical concepts has a game board with, for each player, a player set of musical symbols inscribed thereupon. Players draw cards which define tasks which must be completed in order to progress in the game by marking musical symbols, with a marker, in their respective player sets on the game board. The first player to mark each symbol in the players respective set is the winner. Additional cards are also provided to direct movement of tokens, one for each player, on spaces on the game board, inscribed thereupon as a partial piano keyboard. A player may become a conductor by marking instruments inscribed on the board with the markers. A conductor has increased opportunities to mark symbols in the respective player set and thus of winning the game.

Abstract: A fastening mechanism for fastening eyewear, such as spectacles or clip-on lenses, to clothing has a first and second clips pivotally connected by a pivot. The first clip has jaws is for gripping the eyewear on extremities of pivotally connected respective first and second jaws thereof. The second clip has jaws is for gripping the clothing on extremities of pivotally connected respective first and second jaws thereof. The pivot connects the first lever of the first clip to one of the levers of the second clip, and is situated generally longitudinally opposite the extremities of the first clip, thereby permitting the clips to be freely pivoted relative one another by gravity to suspend the jaws of the first clip, and thereby the eyewear, below the pivot. The jaws of the first clip have cushions which abuttingly contact the eyewear when gripped by the jaws of the first clip.

Abstract: An electromagnetic bandgap device is mountable on a RF disturbing structure of an antenna to minimize signal field disturbance imparted thereby. The RF disturbing structure is oriented in a direction substantially parallel to a path of travel of an antenna signal and located within a field covered by the signal transmitted by a feed. The bandgap device comprises a plurality of RF perturbing elements connected to the RF disturbing structure and spaced apart from one another in the direction substantially parallel to the signal path. The perturbing elements are positioned, configured and sized to direct a disturbed portion of the signal away therefrom to reduce field disturbance generated by the disturbed signal portion interacting with an undisturbed portion of the antenna signal.
