Abstract: 1,053,096. Magnesium hydroxide. ALUMINIUM LABORATORIES Ltd. Oct. 1, 1963 [Oct. 3, 1962], No. 38566/63. Heading C1A. A magnesium hydroxide product consisting of particles finer than 325 mesh is prepared by calcining a naturally occurring starting material, which contains a magnesium compound capable of being converted to magnesia by calcination, at a temperature of at least 925‹ C. and for a time sufficient to produce at least partial periclase development, hydrating the calcined material to provide material containing magnesium hydroxide in dry finely divided form, and separating the fine particle product from the hydrated material. The starting material, which may be a brucite mineral or a magnesite material, is preferably calcined for a time sufficient to ensure that any calcium carbonate and calcium hydroxide present is completely converted to calcium oxide; the resultant lime impurities may be reduced in the finer than 325-mesh fraction by leaching this fraction with water. When the starting material is brucite embedded in granule form in a matrix of calcium carbonate, leaching of lime impurities may be performed between the calcining and hydration steps, the calcined material being leached under selected conditions, for example at a temperature below 100‹ C. and in the presence of a quantity of water to provide lime in dry form, to preferentially hydrate calcium oxide to finely divided calcium hydroxide which may be separated from the dense calcined brucite granules. Such a starting material is calcined preferably at a temperature between 1100‹ and 1200‹ C., the calcined and limeleached material being hydrated preferably with steam under pressure, for example of at least 50 pounds per square inch. U.S.A. Specification 2,208,185 is referred to.

[Also in Division G4] Clutches.-A half-revolution clutch is described for use in a mechanical numerical aggregator. A continuously rotating shaft 41 has keyed to it a ratchet 46 to which is secured a bearing ring 52. A clutch body 43 is rotatable on the ring 52 and has an inwardly extending tooth 53 (Fig. 4, not shown). This is held against a tooth 50 extending axially from a freely rotatable gear 49 by a cast-steel spring 42. A pawl 44 is pivoted to the body 43 and has a tooth 55 (Fig. 5, not shown) urged towards the ratchet 46 by a spring 61. The pawl 44 also has an outwardly extending dog 64 adapted to be engaged by diametrically opposed spring pawls 56 (Fig. 6, not shown) on the armatures 57 of electromagnets 58. Normally the pawl is arrested as shown in Fig. 5 and the gear 49 is not driven. If the electromagnet is excited, however, the armature is withdrawn and the pawl 44 is engaged with the ratchet 46 thus rotating the gear 49 through half a revolution. Shocks are absorbed by the spring 42 and the spring pawls 56. Linkwork.-Linkwork for the mechanical aggregator is described with reference to Fig. 1 (not shown) and diagrammatically with reference to Fig. 2. A number of eccentrics 35 may rotate once through 180 degrees to represent the corresponding ringed numbers, and are interconnected by links having the dimensions shown. They are freely movable except that those shown horizontally in the drawing are constrained to move substantially horizontally by further links (not shown) each pivoted at a fixed point and also pivotally connected to one of the horizontally movable links. The cranks are caused to rotate by the electro-magnetically operated clutches which act through 180 degrees only. The output of the aggregator is taken from the movement of the free end 34 of a link 33. A practical embodiment of a modification is described with reference to Fig. 1 (not shown). It is stated that the vertical links may be cantilevers and that the cranks could be replaced by devices capable of moving links to more than two positions. The horizontal links (or some of them) may be dispensed with.

Abstract: 1,251,095. Heat generating pipes. CHISSO CORP. 29 Oct., 1969 [29 Oct., 1968], No. 53083/69. Heading H5M. In order to satisfy the differing demands for heat along the length of a heat generating pipe of the type comprising a ferromagnetic pipe supplied with alternating heating current confined to the inside of the wall of the pipe by an inner insulated conductor supplied with A.C., one or more of the following factors is varied in accordance with the heat demand of a particular section of the heat generating pipe, during installation; the cross-sectional area of the insulated conductor; the resistivity of the insulated conductor; the magnetic permeability of the ferromagnetic pipe; the resistivity of the ferromagnetic pipe; and the inside diameter of the ferromagnetic pipe. The amplitude and frequency of the currents flowing in inner conductor and ferromagnetic pipes must be kept constant throughout their lengths. As shown, the heating pipe is installed in a fluid pipeline which has a section above ground and a section below ground which requires less heat because of the thermal insulation provided by the soil 10. It is possible to obviate temperature changes of the fluid in the two sections by using a better thermal insulator for the lagging 11 in exposed section than the buried section. However, according to the invention it is preferred to generate more heat in section 1 of the ferromagnetic pipe than section 1<SP>1</SP> by making section 1 of a material of high resistivity and/or permeability by making the inside diameter of section 1 less than section 1<SP>1</SP>, or by making the inner conductor 2 in section 1 of greater resistivity than the inner conductor 2<SP>1</SP> in section 1<SP>1</SP>. It is most convenient to use steel pipes from stock and to use different inside diameter pipes for the sections 1, 1<SP>1</SP>. The inner conductor 2, 2<SP>1</SP> may be electrically in series with the ferromagnetic pipe 1, 1<SP>1</SP> or it may be connected to an A.C. supply and pass through two ferromagnetic pipes lying side by side and connected electrically at their ends so that heating current is induced in the inside skin of the walls of the pipes as in Specification 1,218,216. The ferromagnetic pipe is preferably filled with a good thermal conductor e.g. water, oil or other liquid to transfer the heat of the inner conductor to the ferromagnetic pipe. Applications specified are preventing freezing, heating roads, walls, floors, roofs, runways, railways, bridges transmission lines and tanks.

Abstract: 1,257,064. Automatic weight control. INTERNATIONAL BUSINESS MACHINES CORP. Jan.6, 1969 [Jan.4, 1968], No.734/69. Heading G3R. In a system for producing from a solid a predetermined number of slices having a desired batch weight the difference between the desired batch weight and a batch weight computed from the weight of a number of slices less than the predetermined number is utilized to modify the thickness of the remainder of the batch in a corrective sense. In Fig. 3, a loaf 10, e.g. of bacon, is fed forward by a hydraulic ram 32 and cut by a knife 13 into slices 18 which are grouped into batches containing a predetermined number. Each batch is assembled on a weighing conveyor 16 before being transferred to a conveyor 19. As each slice is deposited on conveyor 16, a transducer Ws and a counter 20 apply electric signals, corresponding to the weight and number of slices present, to a computer 25 which is programmed by signals 33, 34 corresponding to total number and weight of slices desired in the batch. The computer 25 calculates what the total batch weight is likely to be and compares it with the desired weight so that any difference is effective to adjust a valve 27 which alters the velocity at which the loaf is fed. The thickness of the remaining slices of the batch is thus adjusted in a sense tending to give the desired batch weight. Modification of the control by rate and exponential components is referred to.
