Filed: 1990-10-22
Granted: 1994-04-05
Abstract: A substantially one-piece ladder attachment is disclosed. The attachment provides a secure, laterally well-supported platform on which a worker would stand. The invention is particularly useful for an extension ladder, especially one with circular rungs. The attachment of the invention comprises a platform having a single, preferably hollow, vertical support member projecting adjacent one edge thereof. The vertical support is centrally disposed on the edge on which it is located. The vertical support angularly projects from the platform and is connected to an arcuate, horizontally disposed, transversely mounted upper bracket. The upper bracket is intended to engage the rung of a ladder to impart lateral stability to the platform. The attachment further includes a lower, horizontally-disposed, arcuate bracket which is located on the same edge of the platform as the vertical support. The lower bracket is intended to cooperate with a second rung of a ladder to provide lateral, as well as, vertical stability to said platform. In a preferred practice of this invention, grip means are adhered to the top of the platform. In a further preferred practice of the invention, a rung security means, such as a key, is mounted in said upper bracket and through the support member to secure the attachment to the ladder.

Title: Process and apparatus suitable for effecting steel band guidance
Inventor: BIELFELDT FRIEDRICH BERND
IPC: B27N3/24
Filed: 1991-03-21
Granted: 1998-06-02
Abstract: The invention relates to a process for adjusting the alignment of circulating press bands in a continuously operating press and a press adapted to permit such alignment. The press comprises a press bed and a press top, a pair of flexible steel bands defining a press gap therebetween and circulating about said press bed and press top around drive and deflection rollers associated with said press bed and said press top, said press gap including a high pressure zone. The flexible steel bands are aligned by horizontally pivoting the press top and the associated drive and deflection rollers through an angle .alpha. about a central vertical axis while temporarily reducing the pressure in the high pressure zone. The press permits this pivoting by supporting the press top on pivoted support rods capable of parallelogram style movement.

Title: Synchronized horizontal scanning at horizontal frequency multiples
Inventor: FERNSLER RONALD EUGENE
IPC: H04N3/16
Filed: 1991-03-21
Granted: 1995-10-24
Abstract: A first phase locked loop generates a first timing signal at a first horizontal synchronizing frequency corresponding to a horizontal synchronizing component in a video signal. A converter circuit derives from the first timing signal a second timing signal, having a second frequency at a multiple of the first frequency and subject to a variation in frequency at a rate corresponding to the first frequency. A second phase locked loop receives the second timing signal, which can be asymmetric within the period of the first timing signal, and a feedback signal in accordance with the second frequency, and includes a controllable oscillator for generating a smooth horizontal synchronizing signal at the second frequency. The second phase locked loop has a characteristic loop response, determined by a low pass filter, preventing the voltage controlled oscillator from changing frequency as fast as the rate of variation of the second timing signal. This drives the error signal for the controllable oscillator toward an average value, resulting in a corrected, symmetric synchronizing signal at the second frequency. A horizontal output deflection stage may be coupled to the second phase locked loop for synchronized horizontal scanning in accordance with the second frequency. No additional signal processing circuitry is needed to correct the symmetry of the first timing signal generated by the first phase locked loop or the symmetry of the second timing signal derived by the converter.

Title: Locking system for shelving
Inventor: SAUVE PIERRE
IPC: A47B96/06
Filed: 1991-04-08
Granted: 1995-09-12
Abstract: A locking system is disclosed for removably connecting and locking together a transverse member of a shelf and a support bracket. The transverse member has a  locking pin and a resilient biasing locking  knob  both  projecting  outwardly  from  the  member at  a predetermined distance from one another and offset by 90° from one another. The support bracket defines an elongated bed sized to receive the transverse member lengthwise. It has a bottom wall, formed with a first locking aperture, and a side wall at right angle to the bottom wall. The side wall has a top edge and is formed with a locking slot having a slot opening along the top edge and a slot segment extending from the slot opening in the direction of the locking aperture, the latter being spaced from the slot opening a second distance greater than the predetermined distance. The height of the sidewall and the disposition  of  the  slot  segment  are  selected so  that  when  the transverse member is placed into the bed, with the locking pin entered into the slot opening, and move along the slot segment, the locking knob is eventually forced  into the  locking aperture to lock the transverse member and the support bracket together.
