Abstract: 575,827. Clarifying foul liquids. TRIGGS, W. W. (Dorr Co.) Aug. 23, 1944, No. 16091. [Classes 46 and 111] Apparatus for the clarification of polluted liquids comprises a tank having partitioning means the lower edge of which is spaced from the bottom of the tank, so that the tank is divided into two communicating compartments, each compartment having means for the supply and withdrawal of liquid, means being provided for delivering into the second compartment liquid that has been withdrawn from the first compartment and submitted to an additional treatment, and means being provided for withdrawing sediment from the bottom of the tank. In the construction indicated in Figs. 1 and 2, a tank 10 is divided into two compartments 22, 23 by a partition 19 which terminates above the bottom of the tank to leave a space for passage of an endless conveyer 40 provided with scrapers 47 for delivering sediment to a sump 13. Liquid to be treated enters compartment 22 by a feed pipe 6 and is distributed by a launder 25 and baffle 26. At the other end of the compartment is a launder 32 from which liquid flows through pipe 73 to a biologic trickling filter 70. Liquid also flows to the filter through pipe 75 from the outlet'37 of the compartment 23. The filtered liquid is pumped through pipe 82 and valve-controlled pipes 83,84 to the feed pipe 6 and to a launder 30 of the compartment 23. Scum is removed through a slotted trough 58 provided with an adjusting handle 60. In a modification the filter is above the level of the top of the tank and the pump supplies the liquid to the filter. Fig. 7 shows an arrangement in which two filters are used. Liquid from launder 30 is led by a pipe 106 to a well 107 from which it is pumped through pipes 108, 110 to a filter 100. The filtered liquid flows through pipes 101, 102, 103, pipe 103 communicating through pipe 104 with a well 105 from which liquid is pumped to the filter 120. The filtered liquid flows to launder 32. The quantity of liquid supplied to the launder 32 may be larger than that overflowing past the weir 36 whereby a back flow of liquid occurs along the bottom of the tank from compartment 23 to compartment 22, and this facilitates the work of the scrapers 47 on the endless conveyer 40.

Abstract: 356,149. Starting-handles. HEUNER, C., 28, Adalbertstrasse, Berlin. May 29, 1930, No. 16598. [Class 7 (v).] In a starting-handle which is disengaged when the engine starts either forwards or backwards, the handle b is pivoted at d upon a hub a, which is freely rotatable on the engine or starting shaft h and is coupled thereto by a member e actuated from the handle b. As shown in Figs. 1 and 2, the member e slides in the hub a and has teeth f engaged by teeth g on the handle, so that a face m on the slide is brought into engagement with a face l on the shaft h when the handle is turned. Backward rotation of the hub a is prevented by a pawl q engaging a ratchet p on the hub. When the engine starts either forwards or backwards, the member e is moved into the disengaged position, shown in Fig. 2, by one or other edge of the face l on the shaft h, and the reaction upon the hub a acts in the same direction as the rotary movement imparted by the handle b. In a modification, Fig. 7, the coupling member e<1> is pivoted at w upon the hub, and the coupling surfaces l<1>, ml on the shaft h<1> and the member el are each V-shaped with a rounded angle. The shaft h<1> is a short bolt pinned to a tubular shaft, and a ratchet wheel such as p, Fig. 1, is provided on the hub a or on a sleeved extension of the hub surrounding the tubular shaft.
