Abstract: 861,936. Sewage disposal; gravity-separation apparatus. ADAMS-HYDRAULICS Ltd. June 23, 1959 [July 4, 1958], No. 21498/58. Classes 46 and 111. In a system that permits liquid waste alone or both liquid and solid waste to be discharged from a vessel depending on port regulations, a collecting tank 1 is divided by partition 6 into a primary settling chamber 2 for soil waste, which is passed into it from line 4, and a secondary settling chamber 3, into which waste water is passed by line 5. Scum baffles 11 and 12 are provided to prevent substantial amounts of scum being transferred from one chamber to the other. An outlet pipe 13 is provided in the secondary settling chamber 3 and this is connected by line 14 to an ejector pump 15, which empties the effluent through pipe 16, for example, over the side of the ship. The outlet 13 is kept open permanently, and an emergency gravity leak is provided through line 17. In the bottom of the two settling chambers are provided valves 18 and 19. These valves are kept closed when the ship is in harbour or in other restricted waters where discharge of solid waste has to be limited. The waste in both primary and secondary settling chambers may be agitated by passing in compressed air or steam or water under pressure, through lines 24 and 25. Line 21 leads to an ejector pump (not shown) but line 21 and valve 22 may be dispsened with so that the discharge from both primary and secondary settling chambers goes to ejector 15, while chemicals for treatment of the waste may be added, either to lines 4 and 5 or at different levels in the settling tank. Furthermore, partition 6 may have a number of closable apertures so that its effective height may be varied. If the sanitary system has a common outlet for soil and waste water, line 5 may be dispensed with and all waste passed into the primary chamber 2 by line 4.

Title: Improvements in or relating to control systems or apparatus
IPC: G05B1/08
Filed: 1931-08-04
Abstract: 383,310. Regulating switches. ELECTROFLO METERS CO., Ltd., Abbey Road, Park Royal, London.-(Republic Flow Meters Co., Inc. ; 2240, Diversey Parkway, Chicago, U.S.A.) Aug. 4, 1931, No. 22053. [Class 38 (v).] A relay device for use in a step-by-step control system has an index or pointer deflectable in response to a change or variable factor to be controlled, a tactor or member of stepped formation movable into and out of the path of the index or pointer so that the extent of its movement is dependent upon the degree of deflection of the index or pointer, means for imparting to the tactor or stepped member a continuous oscillating or reciprocating movement and a pivotally mounted control lever arranged for movement into any one of a series of different positions according to the step engaged by the index, the control lever being formed with a series of steps which are selectively engaged by an actuator in accordance with the extent of movement of the index. The control lever may be arranged to operate the contact arm of a regulating. switch or to rock a plate carrying a series of mercury switches or alternatively may control the amount of opening of a valve. As shown in Fig. 1, a deflectable index 10 is moved over a scale 11. A pivoted member 12 is oscillated by a motor 16 through a cam 19 so that a stepped member or tactor 13, Fig. 2, is periodically dropped on the movable index, the distance through which the member drops depending on the position of the pointer 10 within a given range, one or other of the steps B .. E arresting the downward movement of the member 12 by engaging the pointer 10. The variable movement of the member 10 varies the position of an actuating crank 37 on a shaft.36 which bears a control lever 42 formed with steps corresponding to those on the plate 13, this lever being positioned by a rod 33 carried by an actuator 31 driven from an eccentric pin 32 on the cam 19. The actuator 31 reciprocates in a slot 30 in a pivoted lever 27 which is positioned laterally by bearing on a roller on the shaft 25, carried by the bell crank 24 actuating the member 12. Thus the plate 42 is positioned in accordance with the deflection of the pointer 10. The shaft 33 passes through a hole in a pivoted guide member 34, the hole being formed at its upper side with a stepped surface similar to that formed on the control lever 35. The guide member is thus reciprocated to remove the locking pawl 41 from the toothed surface of the plate 35 during the automatic adjustment of the latter. The control lever 37 may operate the contact arm 48 of a regulating. switch, Fig. 3, in a motor circuit, a series of mercury switches, Fig. 4 (not shown), in the heated circuits of an electric furnace or may control the opening or closing of a mechanical valve 56, Fig..5.

Abstract: 1,006,935. Circuits employing multi-stable magnetic elements; transistor blocking oscillator circuits. STANDARD TELEPHONES & CABLES Ltd. June 8, 1962 [June 13, 1961], No. 22306/62. Addition to 902,382. Headings H3B and H3T. A storage core having incremental operating states is switched by a current pulse of controlled duration from one stable state to the next, the duration being measured from the time that magnetization reaches the knee of the hysteresis loop by utilizing the abrupt increase in inductance of the core setting winding to stop conduction of a blocking oscillator. The effective switching current of measured duration is obtained in the interval between increase of inductance and cessation of oscillator current, the operation therefore being independent of the different coercive current values required in different regions of the hysteresis loop. As shown in Fig. 1, the core setting winding E is connected in the emitter circuit of a transistor blocking oscillator Trs having transformer primary and secondary windings L1, L2 in the collector and base circuits respectively. The oscillator is switched on by a pulse applied across resistor R and capacitor C, and ceases to conduct when the emitter circuit inductance abruptly increases. In a modification, Fig. 2, the primary winding L1 of the transformer U is directly connected in series with the setting winding.
