Abstract: A journal for coupling a wheel to an axle has a main tubular body portion with a reception space for the axle and a separate locking element. The locking element is mounted in a cradle for pivotal movement about a pivot axis from a release position in which the axle is removable from the reception space to a position in which the axle is secured in position is the reception space. A biasing member such as a magnet, a spring or a tube of resilient material biases the locking element into the secured position.

Abstract: A system for monitoring mechanical waves from a machine which in operation has moving particulate matter therein, the system including at least one sensor located on the machine at a location away from the central axis of the machine, the sensors being for sensing acoustic waves and including a transmitter for transmitting signals representing the sensed mechanical waves to a receiver at a location remote from the sensor(s), a data processor connected to the receiver for receiving signals from the receiver which signals represent the mechanical waves and processing the signals to produce output signals for display on a display means, wherein the output signals for display represent one or more parameters indicative of mechanical waves emitted from the machine over a predetermined period of time.

Abstract: For designing a balanced stair comprising steps with treads (1-15) showing front edges (26), a line of travel (22) is determined on the stair and a reference line is determined onto each step in a predetermined position with respect to the front edge (26) thereof. In contrast to the prior art methods wherein the reference lines, more particularly the front edges (26) or the risers (25) of the steps, are divided along the line of travel (22) on constant mutual distances measured on the line of travel itself, the substantially constant mutual distances (d) between the reference lines is determined according to the invention near the line of travel (22) along a measuring line (27) which is determined for each pair of adjoining reference lines so as to form a substantially constant angle (?) with at least one of the adjoining reference lines thereof. In this way, a stair which is easier to walk on and which automatically shows a more regular nosing line at the outer string (21) is obtained FIG. 8.

Abstract: An actuator position control system for brush-type DC motors. The system includes a sensor, amplifier or differentiator, central control unit (microprocessor), and motor driver. The system utilizes the differential signal di/dt to indicate the falling edges of commutation spikes in the motor current profile. In a first embodiment, an inductor is selected as the signal sensor, because voltage drops across the inductor are directly proportional to di/dt. The voltage drop, L(di/dt), across the inductive sensor is input to the amplifier, amplified, and then sent to the microprocessor. In a second embodiment, a sensing resistor and a differentiator are substituted for the inductive sensor and amplifier, respectively. The microprocessor reads the output pulses from the amplifier or differentiator and compares the pulse count to an input command signal. The microprocessor then sends shaft position control information to the motor driver.

Abstract: An image apparatus has a light-receiving section and a light-blocking section. The light-receiving section receives light from an object to generate an analog video signal. The light-blocking section blocks the light to generate reference signals. The analog video signal is converted into a digital video signal. The reference signals are accumulated a predetermined number of times from a predetermined accumulation starting point on scanning lines forming an image of the object for a specific period. The accumulated signal is averaged to generate an average signal. A reference level of the digital video signal is adjusted based on the average signal so that the difference between the digital video signal and the average signal becomes zero. The number of times for accumulation is decided as 2n that is smaller than a specific number “m”, of the scanning lines for forming the image of the object. The accumulation starting point is decided as (m?2n)/2, “n” and “m” being positive integers.

Abstract: A free standing net system incorporates a full sized floor for easy ball collection and a built in training target secured to a rear wall of a netted enclosure which is functional for multi-sport use. The netting of the enclosure is 1000 denier polyester, treated for long wear and UV resistance. The floor is constructed of high density nylon with a water-resistant polyurethane coating. The sleeves located at the peripheral edges of the netting are engaged by two shock-corded poles to provide a cantilevered frame portion projecting above and towards the sports enthusiast. The cantilevered frame portion is specifically designed to trap wedge shots during golf practice. Angled side wings of the netted enclosure allow free swinging motion with any golf club to provide a wide angle of capture during golf practice swings.
