Abstract: An electric typewriter of the type having individual type elements for each character has attached thereto a system for controlling the actuation of the type elements and the control functions of the typewriter by digital signals. The digital signals may emanate from a remote central processing unit or other device. The control system is an attachment to the typewriter which does not interfere with the normal manual operation of the typewriter. The control system is mounted in a housing which is placed under the typewriter in predetermined alignment with the key lever actuation means and employs an electromagnetic actuator to set a condition for a mechanical actuator for each key lever. A mechanical actuator initiates a key stroke if the electromagnetic actuator is positioned in an ON position and does not initiate a key stroke if the electromagnetic actuator is in the OFF condition.

Abstract: A linear electromyographic biofeedback system operates over a dynamic range of at least one thousand to one. That is, the system remains linear from input levels of approximately one microvolt to input levels in excess of one millivolt. The linear electromyographic biofeedback system includes a sensitive transducer which is followed by a protection circuit and connected to a differential amplifier for eliminating common mode noise. The output of the differential amplifier is filtered and amplified to further eliminate unwanted signals. This filtered signal is rectified and averaged in a third order averaging filter to obtain a close approximation of a time averaging without the necessity of discrete timing periods.

Abstract: A two or more wheeled vehicle is driven by a DC electric motor having its output shaft connected to a frictional drive member which bears on the circumference of a driven wheel. The drive motor is face or flange mounted on mounting bracket which is constructed of a metal stamping or an integral combination of two stampings. The mounting bracket may take any one of several forms, depending upon whether or not it is desired to hold the power source in addition to the drive motor. In one form, the mounting bracket is adapted to hold a source of power for the motor such as a storage battery. The drive mechanism is adapted to permit the vehicle to be either motor driven or human driven or both in combination. The mounting of the drive mechanism requires no modifications to the vehicle frame and uses the caliper brake bolt as a precise locator to insure universal adaptability of the drive mechanism to any vehicle having such a caliper brake bolt.

Abstract: A baking pan has a removable end portion which allows easy access to the baked goods after baking. The removable end portion may be used as a spatula to lift the baked goods from the baking pan with minimum damage of the baked goods due to sticking.

Abstract: A self-retracting sight is mounted on the shaft of an arrow to facilitate sighting and aiming of the arrow and thus improve accuracy either in target shooting or in bow hunting. The arrow mounted sight is attached at a point forward of the feathers and has a notch or a peepsite hole cut in a top portion to facilitate sighting. The sight is curved to match the curvature of the shaft of the arrow and is lightweight so that it falls back against the shaft when the bowstring is released by the archer.

Abstract: A garment bag sealing machine includes a loading pole for loading a bagged garment onto said machine, the loading pole being movable to transfer the bagged garment to a pick-off unit and lifting cylinder which lifts the bagged garment until a detector, such as a photo electric cell, detects the bottom of the garment at which point a sealing unit, such as a heat sealing unit, is brought to bear upon the bottom portion of the garment bag causing the garment bag to be sealed. The lifting mechanism then carries the bagged garment to a slide rail system which then carries the garment to a packing or removal station.

Abstract: A utility trailer has a frame which may be lowered to ground level at both the front and rear portions of the trailer to permit easy access and to facilitate loading and unloading of heavy vehicles or other items. The trailer frame is attached to a U-shaped axle which in turn is connected to a wheel suspension support. The wheel suspension may be raised or lowered by rotation of the wheel suspension about the axle allowing the rear of the trailer frame to be raised or lowered. The front of the trailer frame is connected to a cable controlled by a winch which will permit the lowering or raising of the front part of the trailer frame. Locking pins are employed to lock the suspension and the front portion of the trailer frame in place during travel.
