Abstract: A yarn tension detector having a cage-like form pivotably moveable between predetermined limits about the pivot point and under the control of the tension of a moving yarn. The detector includes a pair of spaced abutment members in an electrical circuit with a lamp. The cage-like member makes a circuit whenever it engages one or the other of the abutments to thereby cause the bulb to light. The member also includes oppositely directed guide formations about which a yarn is trained and as the yarn is fed from a creel to, for example, a tufting machine the tension in the yarn as it moves through the guide formations pivots the member. One of the guide formations progressively opens when the yarn tension is in excess of a predetermined high tension to release the yarn from the detector after it has indicated the yarn tension fault.

Abstract: A signalling device mounts on a fishing rod to signal a hooked fish. Two relatively movable contacts are axially aligned in the direction of the rod's length. An axial bore through the forward-most contact allows a string to pass therethrough and connect to the rear-most contact. The string clamps to the fishline, whereby the force of a hooked fish will close the contacts to actuate an alarm.

Abstract: A brake cable switch is disclosed for indicating when a cable is tensioned at or beyond a predetermined value, comprising a hollow rectangular housing containing an hermetically sealed chamber, said housing including a flexible top wall having a convex outer surface the axis of which extends longitudinally along the housing, said top wall being biased away from the housing bottom wall, a pair of switch contacts mounted in the chamber for operation between a normal first electrical condition and a second electrical condition, and a pair of fastener devices arranged at opposite ends of the housing for mounting the housing on an untensioned brake cable.

Abstract: A safety device for lifting magnet has sensor means responsive to flux produced by the device in the magnetic circuit including the body to be lifted, a transducer responsive to the lifting tension produced by the device together with a signal translation circuit effective to compare signals from the sensor and from the transducer and to provide an output indicative of a safety margin between lifting tension and the field available for lifting.

Abstract: An alarm activating device is provided for closing a normally open circuit upon release of body pressure upon the rearward wall of the device, comprising a first, second, and third plate supported respectively in substantially parallel alignment behind a mounting plate, which mounting plate is adapted to be secured behind a belt in close proximity to a body, the first and third plates being spaced-apart and movable together from a position wherein one contacts the second plate, to a position where the other contacts the second plate, including means for applying constant positive pressure to the first plate opposite the second plate, and further including a first and a second contact in series circuit relationship, supported adjacent one another in alignment on the first and second plates.

Abstract: An alarm device to be attached to an enterostomy incontinence drainage pouch which will provide warning when said pouch becomes filled. A miniaturized alarm is attached to the drainage pouch by clamp means. A cable is secured to the actuating mechanism of the miniaturized alarm and is attached across the drainage pouch in such a way that the outward expansion of the pouch when it becomes filled will exert a force against the cable, causing the alarm to be actuated.

Abstract: A line-actuated fishing rod light includes an electrically conductive bracket, a battery therein, a threaded-base, bulb, and a spring wire trigger arm coiled to provide a socket for the bulb and extending beyond the socket to form a trigger finger. A fishing line is wrapped around the finger and, upon a fish strike, pulls the arm and socket toward a battery terminal. The bulb lights on contact of its terminal with the battery, through the circuit provided by the battery's rear terminal, a rear wall of the bracket, the bracket, the spring wire arm, the coil socket, and the bulb base. The line disengages from the trigger arm upon playing the fish, so that the light does not interfere with the line during such time. Also, the bulb can be rotated into and out of the coil socket to adjust the light's sensitivity to differing forces exerted on the line.
