Abstract: 1,090,714. Feed water heating. FOSTER WHEELER Ltd. Dec. 13, 1965 [Dec. 14, 1964], No. 50794/64. Heading F4A. Feed water is pre-heated by passing through a coil 20 in the steam and water or water drum 12 of a boiler 10, before being heated in economiser 22 in a flue 24 through which pass exhaust gases from flue 18 of boiler 10, and/or exhaust gases from a Diesel engine. The heated water is then fed into drum 12. A steam generating coil 26 fed by pump 27 from water drum 11 may also be incorporated in duet 24. Valve controlled by-passes may be provided for the coil 20 and the economiser 22 (see Fig. 4, not shown). The invention may be applied to a compound boiler (see Fig. 3, not shown) wherein low pressure steam is generated in a drum (32) by high-pressure steam itself generated in boiler (10a), passing through tube nest (30). The feed water for drum (32) is pre-heated in coil (34) before passing to economiser (22a), in duct (36).

Title: Process for working up mixtures of c aromatic hydrocarbons and simultaneously obtaining toluene, ethyl benzene and cumene
Inventor: SMEYKAL KARL
IPC: C07C6/12
Filed: 1963-12-31
Abstract: Mixtures of C9 aromatic hydrocarbons are "worked up," producing toluene together with ethyl benzene and/or cumene (isopropylbenzene) by a process consisting in treating the mixtures with benzene in the presence of a Friedel-Crafts catalyst and subjecting the reaction product to fractional distillation after removal of the catalyst.

Abstract: 1,135,778. Granular magnesium ammonium phosphate. SCOTTISH AGRICULTURAL INDUSTRIES Ltd. 21 Nov., 1966 [3 Dec., 1965], No. 51433/65. Heading C1A Granular fertilizer compositions comprising magnesium ammonium phosphate are prepared by reacting and simultaneously granulating by a wet granulation technique a mixture comprising NH 4 H 2 PO 4  and at least one of the compounds MgO, Mg(OH) 2  and MgCO 3 . The term "granular" denotes a particle size range of <SP>5</SP>/ 16  inch-100 mesh B.S. sieve. By "wet granulation technique" is meant agitation of the mixture in a granulating device (e.g. a rotating drum, a pan granulator or a pin mixer) in the presence of sufficient water to effect granulation. Calcined magnesite (MgO) is the preferred magnesium component. When two or three of the aforementioned magnesium compounds are employed, they may be in chemical combination, as in 3MgCO 3 .Mg(OH) 2 .4H 2 O. The reactants are preferably finely subdivided, although the monoammonium phosphate may alternatively be in the form of an aqueous slurry. Additional fertilizer ingredients such as nitrogenous compounds and/or potassium salts may be added to the reactant mixture. The granules obtained are preferably dried to remove excess moisture, and by heating at about 90‹ C. the magnesium ammonium phosphate is converted to the monohydrate state.

Abstract: 1,118,820. Transferring liquid cargoes to and from rail tankers. WHESSOE Ltd. 28 Feb., 1967 [7 Dec., 1965], No. 51942/65. Heading B8E. A stationary installation has a coupling 11 on a loading arm 10 for connection to a corresponding coupling on a rail tanker for the transfer of liquid cargo. The arm 10 is mounted on a trolley 13 for movement towards and away from the tanker by a ram 16 while the trolley 13 is mounted on a further trolley 17 movable parallel to the direction of movement of the tanker by a ram 20. A light source and lens 21 and a receiving lens 22 are mounted on the trolley 17.

Abstract: 1,272,696. Padlocks. CHU MAN KUI [trading as WINCENT METAL FACTORY]. 4 Nov., 1970, No. 52519/70. Heading E2A. A combination padlock comprises a casing 10, a shackle 22 movable relative to said casing and having one limb 21 extending through an aperture 12 into said casing, a further aperture 11 in said casing through which the other limb 20 of the shackle can pass, a pawl carrier 25 pivotally mounted in said casing and provided with an arm 32, a spring loaded pawl 27 mounted in said carrier and capable of engaging in a recess or notch 23 provided in the limb 20 of said shackle, a plurality of co-axial rotatable discs 34, 35 and 49 mounted in said casing, said discs being provided on one or both faces with a projection and with a peripheral recess 43, resilient means, i.e. a spring 38, for urging the discs towards one another, means for manually rotating one disc, the other discs being capable of being rotated through engagement of the or a projection with a projection of an adjacent disc, rotation of said manually rotated disc in alternate directions of rotation through predetermined angular amounts causing the discs to rotate to positions in which the peripheral recesses are aligned one with another and with the arm of said pawl carrier to allow said carrier to pivot in order to disengage the pawl 27 from the recess or notch 23 of said shackle, means being provided to effect random rotation of at least one of said discs during inward movement of the shackle relative to said casing in order to destroy the alignment of the recesses of the discs. As shown, the disc 49 is secured to a knob 47 carrying a graduated dial 52 any of the divisions of which may coincide with an indicator mark. The code required for releasing the padlock is dependent upon the circumferential positioning of the projections 39, 41 42 and 50 relative to the recesses 43 of the discs. In operation, the knob 47 is rotated clockwise and anticlockwise as is necessary bringing the appropriate graduation of the dial into alignment with the indicator mark until the recesses of the discs are in alignment when the arm 32 enters the recesses to cause disengagement of the pawl 27 from the notch 23 when the shackle may move outwardly relative to the casing; the limb 21 of the shackle is guided by a projection sliding along a slot in the casing and a recess on the member 24 sliding along a track 59. In pushing back the shackle to fasten the padlock, the arm 58 strikes an arm of the lever 33 the rotation of which causes the discs to be rotated in a random manner, the pawl 27 re-engaging the notch 23.

Title: Detecting flow rates of conductive liquids and milking cows by machine
IPC: A01J5/017
Filed: 1973-11-15
Abstract: 1488251 Milking machinery R CRANE & CO Ltd 3 Feb 1975 [15 Nov 1973] 53094/73 Heading AIM Apparatus for automatically removing the teat cups from a cow on the cessation of milking includes a milk flow indicator comprising a receptacle 12 with an inlet pipe 13 and an outlet pipe 16 having a slit 16A presenting an effective cross-sectional area proportional to the height of the milk in the receptacle. Two electrodes are provided, one 15A extending to the base of the receptacle, the other 15B being adjustable in height. A baffle 14 positioned between the inlet and outlet prevents splashing. When the milk flow is reduced below an amount determined by the level of milk in the receptacle falling below electrode 15B, a signal is transmitted to an electronic circuit, and after a 20 second delay, an electric motor is energised to wind-in a cord which operates a switch to release the vacuum in the teat cup cluster and hence release the cluster from the cow. The cord also acts on a pivotal arm from which the cluster is suspended and moves the cluster to a rest position which allows the cow to back out of the stall. If there is a resumption of flow during the 20 second delay, the control circuit is immediately returned to its inactive condition. Manual depression of a starter button energises the electric motor to unwind the cord to permit the teat cups to be put on a cow, and a suitable delay period ensures that the control circuit cannot initiate teat cup removal before milk flow has begun. In a modification the outlet slit 16A is formed in the wall of the receptacle 12.

Abstract: 1,211,098. Steam traps. K. FUJIWARA. 23 Nov., 1967 [29 Nov., 1966; 10 June, 1967], No. 53462/67. Heading F4U. In a free-float steam trap having a float made of two interconnected parts, the orientation of the float within the valve chamber is restricted so that the junction between the two parts cannot contact the seat of the condensate discharge valve. As shown, the float 6 comprises two hemispherical parts 7, 8 welded together at 20 and is arranged to contact a valve seat 12 at a predetermined low level of condensate. Part 8 is thicker than part 7 so that the centre of gravity is displaced to the lower side of the float along its vertical axis and weld 20 consequently remains parallel to the condensate surface as the float rises and falls. The same result is achieved by providing a weight within the lower part 8 (Fig. 3, not shown). The trap has an inlet 3, a filter 16 and an outlet 5.
