Title: Improvements in water softening apparatus of the base-exchange type and in filters
IPC: C02F1/42
Filed: 1935-01-18
Abstract: 437,857. Softening water; filters; electricmotor control systems. UNITED WATER SOFTENERS, Ltd., Aldwych House, Aldwych, London. Jan. 18, 1935, No. 1760. Convention date, Jan. 27, 1934. [Class 46] [See also Group XXXVII] A battery of base-exchange water-softeners or filters has a common timing mechanism to start the reconditioning cycles of the several units in succession at predetermined intervals and each unit has associated therewith a device for automatically cutting off the discharge of water therefrom if the treating-material is spent before the timing mechanism initiates its reconditioning cycle. The invention may be applied to apparatus with units having reconditioning means comprising a multi-passage valve rotated discontinuously by an electric motor 50 as described in Specification 437,856, but the circuits are modified so that the contact closed by the cam 28 turned by the meter 26 does not complete a circuit to energize the magnet 53 of the motor switch 52 to initiate reconditioning but closes a circuit through a magnet 31 operating a valve controlling the supply of pressure liquid to a diaphragm 35, which closes a valve 36 in the pipe through which water is discharged from the meter 26. The central timing device comprises a motor 4 which by means of an adjustable crank 7, pawl arms 8, 9 and a ratchet wheel 10 turns a shaft carrying cams 18, 22- one for each unit of the battery. Reconditioning in any unit commences when the corresponding cam closes a contact 19 in a circuit comprising a contact strip 44 and the magnet 53, as described in the above-mentioned Specification. The circuit of the motor 4 may be controlled by a hand switch 16 or by a float in a common storage tank 3 for the treated water. The operating magnet of a switch 92 controlling a motor 93 which drives a pump 94 supplying the water to be treated to the apparatus may be arranged in parallel with the motor 4. The meter 26 may be replaced by a device which causes electrical apparatus to function when the discharge from a unit becomes slightly hard and therefore a slightly better conductor of electricity than soft water.

Abstract: 638,063. Thrust spoilers for jet-propelled aircraft. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. Jan. 22, 1946, Nos. 2164 and 2165. Convention dates, May 12, 1945 and Nov. 21, 1945. [Class 4] [Also in Group XXVI] A thrust spoiler for a jet-propelled aircraft comprises a pair of deflector flaps which, in the retracted position, form part of the rear portion of the jet pipe or of the aircraft structure enclosing the jet pipe, and are so arranged that when extended their front and rear edges are disposed to the rear of the positions occupied when retracted. In the construction shown in Figs. 3 and 4, two flaps 2 are provided, and are movable about a common pivot 10 by a linkage 25, 28 actuated by a control rod 30. When fully extended the rear edges of the flaps meet at 5 and two forwardly-directed jet outlets 8 are formed. The discharge through the outlets 8 may be made asymmetrical by rotating the flaps 2 about the pivot 10, Fig. 4. In addition, the control member 30 may be interconnected with the aileron controls. Auxiliary guide vanes 34 may be provided in the discharge outlets. The flaps 2 may be deflected automatically when the aircraft approaches or makes contact with the ground. Fig. 12 shows an arrangement in which movement of the shock-absorbing members 66, 67 of the undercarriage closes contacts 64, 65 to start an electric motor 61 by which the flaps are opened when the landing wheels contact the ground. In an alternative arrangement, Fig. 13 (not shown), the motor contacts are closed by a feeler suspended from the undercarriage and which comes into contact with the ground before the landing wheel. The Specification as open to inspection under Sect. 91, comprises also an arrangement, Fig. 1 (Cancelled), in which the jet tube is provided with a conically-shaped throttle member i, which may be mechanically connected to the flaps 2 in such a way that the degree of throttling is reduced when the flaps are extended to their operative position. This subject-matter does not appear in the Specification as accepted.

Wheel 190 engages teeth 162 on the drum 62 which is thus indexed once every ten minutes. Between indexing of the drum 62, the inner surface of drum 61 engages a tooth on the gear wheel 188, preventing it from rotation. A flexible arm 196, which is fixed at one end and which engages gaps between teeth 162 at its other end, assists in preventing rotation of the drums between indexing. The hour-indicating drum 63 is driven by the drum 62 by a similar mechanism. Drum 61 is driven once a minute via intermediate gearing by an electric motor (30), Fig. 1 (not shown). The time is displayed by numerals on the peripheries of the drums, which are transparent. Light from a lamp (14) illuminates the numerals which are formed by raised portions surrounded by a coating of opaque material.
