Title: Combined anaerobic treatment and clarification unit
Inventor: KIVELL WAYNE ALLEN
IPC: C02F3/28
Filed: 1955-09-15
Abstract: 773,124. Digestion apparatus; gravityseparation apparatus. DORR-OLIVER, Inc. Sept. 15, 1955, No. 26415/55. Class 111. Sewage or industrial waste is introduced e.g. at 15 to an anaerobic digestion compartment 20 and displaces therefrom a quantity of relatively solids-free liquid through a pipe 21 to the feedwell 23 of a superimposed clarifying compartment 24, whence clarified effluent emerges at 27 and sludge is scraped back into the digestion compartment through a boot 45 and past a rotating closure plate 46. Some gas formed in the digestion compartment collects under the partition wall 12, thus forming a thermal seal, the remainder thereafter collecting in a gas chamber 53. Gas is prevented from rising into the clarifying compartment by overlapping of the upturned edge of plate 46 and the lower edge of boot 45, and upward liquid flow at this location is prevented by the downward flow of solids. Scum in the digestion compartment is broken up by inter-engagement of rotating blades 39 with fixed blades 40. Sludge in the bottom of the digestion compartment is circulated mainly towards a well 19 by scrapers 32, whence it is withdrawn at 35. Influent may alternatively be introduced to the well 19 by pipe 17 instead of at 15, in which case sludge is withdrawn at 33. Mixing of the influent with the digestion compartment contents is assisted by the rotation of scraper arms 30, blades 32 and supporting truss 31. The effluent may pass to a sand filter (not shown), which, as a result of the above process, has no tendency to clogging or ponding, even when the influent contains grease, soap and detergent solids.

Title: Improvements in a driving and braking circuit for an electrically driven apparatus
Inventor: WENDLEBURG FRANK WALTER
IPC: B66C13/30
Filed: 1954-09-17
Abstract: 751,082. Control of A.C. motors. HARNISCHFEGER CORPORATION. Sept. 17, 1954, No. 27034/54. Class 38(3) The bridge of a travelling crane is driven by an induction motor 11 which has a wound rotor and is coupled to a holding brake 12 and an alternator 153 as well as an eddy-current brake 17 which is brought into operation during. deceleration of the motor to prevent abrupt changes of speed. Movement of a master controller 35 to a first forward position closes contactor 28 to connect the primary winding of the motor to the supply, the secondary winding being connected to a resistor grid 58. At the same time, brake windings 69, 70, are energized through rectifier 72 from the primary circuit of the motor to release the holding brake. Further movement of the controller in the forward direction causes removal of the secondary resistance of the motor in sequence until the maximum speed is reached on the fifth step of the controller. On the third step, a relay 92 is energized and is maintained closed until the controller is returned to the "off" position. The secondary resistance of the motor is gradually re-inserted by returning the controller towards its neutral position, and, in. moving from the third to the second position of the controller, a relay 111 is energized through contacts of the relay 92. This causes energization of windings 128 of the eddy current brake from transformer 113 and rectifier 149, resistors 120, 121 being connected in series with the brake windings. Movement of the controller from the second to the first position effects the inclusion of the whole of resistor 58 in the motor secondary circuit, and simultaneously short-circuits resistor 120 in the excitation circuit of the eddy-current brake so that the speed of the motor is smoothly reduced to a low stable speed in preparation for the application of the holding brake in the "off" position of the controller. Operation of the motor in the reverse direction is similar to that described. In the event of power failure, a relay 126 drops out and transfers the source of excitation current for the eddy-current brake to alternator 153 and rectifier 154. The alternator also supplies current to the windings 69, 70, of the brake 12. As long as-the bridge is travelling at an appreciable rate, the alternator provides sufficient current to release the holding brake, the eddy-current brake being excited to provide smooth deceleration. The self-inductance of the windings of the holding brake is arranged to prevent premature application of the brake when changing over to the emergency excitation circuit. The alternator 153 may be replaced by other sources of emergency excitation. The eddy-current brake may be brought into action during acceleration by means of a manual switch 139.
