Abstract: SHOCK ABSORBER FOR SWIVEL CASTER               ABSTRACT OF THE DISCLOSURE    A device for use with a bearing construction for a swivel caster mountable on a caster mounting plate and including a yoke having a swivel plate pivotal about a pivot axis.  A securing device is provided for securing the yoke to the caster mounting plate.  The bearing con-struction is composed of a ball bearing retaining struc-ture which normally abuts against the underside of the caster mounting plate.  An elastomeric member is mounted between the bearing construction and the caster mount-ing plate.  The elastomeric member has a compressible characteristic sufficient to maintain the caster firmly connected to the mounting plate while simultaneously being capable of yielding to a sufficiently large force applied to the yoke to permit a relative movement be-tween the mounting plate and the yoke to thereby prevent permanent deformation to the yoke when an abnormally high force is applied thereto.  The securing device includes structure for limiting the initial compres-sion of the elastomeric member between the bearing con-struction and the mounting plate.         CROSS REFERENCE TO RELATED SUBJECTS    This application is related to Canadian Patent No. 744 090.

Abstract: WADDINGTON DRIVE HAVING A CAM ACTUATED         BY AN INTEGRAL FLYWEIGHT     Abstract of the Disclosure An improved Waddington drive, employed here as a bicycle wheel hub, provides an automatically shifting transmissio driven by an operator's foot pedal crank.  A number of planet gears journaled for rotation in the hub engage and revolve around a fixed sungear on a mounting shaft thereby carrying and rotating the hub with them,  The planet gears are connected through one-way clutches to cranks whose arms follow a cylindrica cam, the eccentricity of which is variable as a function of speed and torque.  The cam is pivotally mounted from the rotating input shaft and its eccentricity is controlled by the reaction force between the cam and its followers, the centrifugal force on the cam, and a restoring force developed by a cantilever spring urging the cam to return to an initial eccentricity selectable to match the operator's capabilities.  The centrifugal control force is developed by a flyweight integral with the cam and by a counterweight serving to dynamically balance the input shaft.

Granted: 1981-10-27
Abstract: Abstract of the Disclosure An apparatus and method for making reliable and repeatable welds between lead battery lugs disposed on either side of a plastic partition.  An instrument measures the resistance of the welding jaws, electrode tips and contact of the tips with the battery lugs and sends this information to an interface controller where the amount of current required to generate the heat to make a reliable weld is determined from the resistance measurement.  Information is then sent to a transformer controller which energizes a transformer to provide the correct amount of current to the welding jaws.  While the welding is in progress, an instrument measures the current flowing through the electrode tips and lugs and this infor-mation is sent to the interface controller for comparison with the determined value.  After the weld is complete, the resistance is again measured and, if the weld is found to be inadequate, the battery is marked as a reject and a reject mechanism discards the battery from further process-ing in the assembly line.

Abstract: PROCESS OF PRODUCING FUEL GAS AND FLUIDIZED BED REACTOR FOR CARRYING OUT THE PROCESS ABSTRACT          Fine-grained to coarse-grained or fibrous fuels of organic origin are processed with omnidirectional relative move-ments of fuel particles and gasifying agent particles and with subsequent formation of a combustible mixture from the fuel gas product and oxygen, followed by a combustion of the mixture in a prime mover.  The fuel is gasified in a fluidized bed under such conditions that the fuel gas product is entirely or sub-stantially free from contents of heavy hydrocarbons, hydrocarbon compounds, substances which form tarlike condensates when cooled below their dew point temperature, as well as phenols and phenol compounds.  These conditions can be adjusted by any person skilled in the art in that the height of the fluidized bed is maintained below an upper limit at which the fluidized bed is torn open more than locally and that the height of the fluidized bed is maintained above a lower limit at which the fuel gas still contains the above mentioned substances.

Abstract: TITLE: FLUID PRESSURE ACTUATED BY-PASS AND RELIEF VALVE     ABSTRACT OF THE INVENTION    A fluid pressure actuated by-pass and relief valve are positioned between a source of fluid under pressure and the hollow interior of a rotor in a fluid pressure actuated downhole drilling motor.  The valve includes a hollow mandrel with an inlet opening at one end and an outlet opening at the other end connected to the rotor interior and slidably received in a movable sleeve.  Fluid pressure at a first predetermined value moves the mandrel into the sleeve to block the inlet opening such that the fluid by-passes the valve and flows between the stator and the rotor to rotate a bit.  Fluid pressure at a higher second predetermined value moves the sleeve relative to the mandrel to expose the inlet opening and relieve the fluid pres-sure on the rotor and the stator.  The movement of the sleeve exposes a greater surface area thereof to the fluid pressure such that a spring moves the sleeve back to block the inlet opening only at an intermediate third predetermined fluid pressure value. A second spring moves the mandrel relative to the sleeve to expose the inlet opening when the fluid pressure falls below the first predetermined value.  In two alternate embodiments, the mandrel cooperates with a stationary sleeve and the movable sleeve cooperates with a second inlet opening to separate the by-pass and relief functions.

Abstract: SIGNAL CODING FOR TELEPHONE    COMMUNICATION SYSTEM                    ABSTRACT         A telephone communication system reversibly converts input signals into adaptive delta modulated (hereafter ADM) signals and then into pulse code modulated signals.  In one embodiment, an encoder of a telephone communication system receives analog signals, for example voice signals, in a com-parator which also receives an analog signal from an integra-tor for periodically providing ADM signals.  The ADM signals are provided to a pattern detector responsive to predetermined patterns of the ADM signals to supply a step size increase or decrease signal to the integrator which then generates the analog signal compared with the input signal for forming the ADM signals.  Each signal from the pattern detector is a linear pulse code modulated (hereafter LPCM) signal representing a signal increment corresponding to that represented by the ADM signal.  Each LPCM signal increment is then added to the total of each preceding LPCM signal increment to form LPCM signals representing the input analog signal.  The LPCM signals are then periodically sampled and each sampled LPCM signal converted into a corresponding compressed pulse code modulated (hereafter CPCM) signal for switching and further transmission.  In a receiving path of the embodiment, a converter converts input CPCM signals into LPCM signals.  Each LPCM signal together with a locally generated signal repre-senting the preceding LPCM signal is provided to a digital comparator which forms an ADM signal encoded in response to the relative magnitudes of the input and generated LPCM     signals.  The ADM signals are then provided to further means controlled by patterns of the ADM signals for providing a pattern controlled signal to an integrator which integrates the pattern controlled signal into an a nalog signal corre-sponding to the CPCM signal input to the receiving path of the embodiment.
