Abstract: An automatic, hydraulically-operated steering assembly for a towed vehicle is disclosed. Each set of steerable ground-engaging wheels of this towed vehicle is steered by a double action piston fed by a pair of hydraulic hoses connected to a control valve actuated by a pivotal device and a control rod. A bypass is provided between the two hydraulic hoses to allow the hydraulic pressure to slowly equilibrate in the two hoses and thus allow the wheels to return in their straight line position when the source of pressurized fluid is normally disengaged or in the case of a failure of the hydraulic system. Advantageously, the valve is controlled by a push-pull cable having one end attached to one wheel and another end to the valve. The towed vehicle may comprise one or more sets of steerable wheels. In the latter case, the front and rear sets of wheels are adapted to pivot in either direction, the middle set being non-pivotal.

Patent CA-2122164-A1 (CA)
Inventor: SINGMIN ANDREW
IPC: G10K11/16
Filed: 1994-06-15
Abstract: Reduction in well being with subsequent erosion in productivity of information workers located in open plan offices is an increasing concern to office managers responsible for the effectiveness of their staff.  To this end therefore, this invention has shifted the focus away from the traditional approach of concentrating on the technological specifications of white noise systems and instead focused on the more important issue of psychologically improving the well being of the user of this particular system.          The invention places the greatest emphasis on being aesthetically pleasing to the user, easy to use and deliberately tailored to be integrated into study programs  for the evalaution of people's responses to the use of white noise as an effective sound masking agent  against  peripheral  irritating  noise,  from  co-workers conversations and general office-derived 'noise'.          The invention lays claim also to be able to electronically monitor the  ambient  background  noise  and  to  use  this  signal  to automatically adjust the volume of the white noise stimulator thereby eliminating the need for the user to continually make manual adjustments as the background noise dynamically changes.            The aesthetic design of the total system is adaptable to suit the application in question and there are no drawings therefore as would normally accompany such an application.   Similarly,  the electronic design is infinitely variable to meet the application and therefore  is also not  submitted.   The claim lies  in the improvement to existing process by the deployment of an application specific customized system.
