Abstract: The invention relates to a power transmission and steering arrangement for crawler-type vehicles or vehicles provided with non-turning wheels, when the problem is that a fully exact arrangement, operating within a wide range of speed, is lacking. The present invention remedies the deficiency by offering an arrangement in which the rotation motion of a hydraulic motor 20, which is driven by a continuously adjustable hydraulic pump, is coupled by means of the epicyclic part of the arrangement with a forward- /backward-leading primary rotation motion so that the one drive axle 35 rotates at the speed: primary speed + control speed, and the second drive shaft 35 at the speed: primary speed - control speed. <IMAGE>

Abstract: For the preparation of titanium dioxide by the sulphate process, titanium slag and ilmenite are used as starting materials and are digested simultaneously but separately, i.e. different amounts of 98.5% strength and 85% strength sulphuric acid are added to them, the temperatures being slightly below the starting temperatures and the digestion reactions being initiated by adding a small amount of superheated steam. After the digestion, the two mother liquors are mixed and are processed together to give TiO2, the 23% strength dilute sulphuric acid obtained in the process being concentrated to about 85% with isolation of metal salts and being recycled. Highly concentrated sulphuric acid, preferably obtained by roasting the metal sulphates obtained in the process, is predominantly used for the titanium slag digestion, while the excess concentrated 85% strength sulphuric acid is used predominantly for the ilmenite digestion, so that the dilute sulphuric acid obtained can be virtually completely reused in an economical manner.

Abstract: 1291692 Modulating light MULLARD Ltd 9 Jan 1970 1173/70 Heading H4F An electro-optic crystal of the m3m class, e.g. barium titanrate above its Curie point, KTN, or other perovskites, is provided with a pair of transport electrodes e.g. of tin oxide, for setting up an electric field in the crystal which is not parallel to any of the crystallographic axes. Light e.g. of wavelength 0.3-6 Ám for KTN, may be directed through the crystal in a direction which is not parallel to the crystallographic axes and which is not normal to the field direction. The light and field may be applied in substantially parallel directions and a maximum effect is then obtained when that direction is at 45 degrees to the crystal axes. Thus in Fig. 1 (not shown) such a crystal is disposed between crossed polarizers and has electroded (0, 11) faces perpendicular to the optic axis. In one embodiment, monochromatic light is intensity modulated by applying voltage pulses to the crystal and detected by an indium antimonide detector. The amplitude of such pulses may be reduced if a D.C. bias is also applied due to the square law dependence of the retardation. If the light source is broad band, the crystal and polarizers may form a variable filter. In a light deflector, Fig. 3, plane polarized light is passed through a series of such crystals interleaved with a series of uniaxial crystals e.g. of calcite, which are orientated so that their privileged directions are at 45 degrees to those of the preceding and following active crystals. Each uniaxial crystal has half the thickness of the preceding uniaxial crystal, so that application of a half wave voltage to one of the active crystals results in the appropriate binary deflection. Such an arrangement may be used for a display on a screen, of for addressing an optical storage bank such as an array of photo-diodes. Reference has been directed by the Comptroller to Specification- 1,258,633.

Abstract: Streptin, a thermostable basic antibiotic soluble in water, acid alcohol and dilute acids, insoluble in ether, chloroform and acetone, and active against gram-positive and gram-negative organisms (especially Micrococcus lysodeikticus, M. conglomeratus, Staphylococcus albus and S. aureus), is produced in the form of a crude aqueous solution by cultivating Streptomyces reticulus-ruber for about 1-2 days at about 30 DEG  C. with agitation and aecration in a medium containing about 0.5-2 per cent of a nutrient substance consisting of protein material or mixtures thereof with carbohydrate and having a pH of about 7.0-8.2 (which may be maintained by means of a phosphate buffer), or for about 12 days under similar conditions in a synthetic nutrient medium, and filtering off the vegetative matter. The streptin may be isolated in the form of a salt by treating the filtered culture broth with about 1 per cent of activated charcoal, eluting with low normality aqueous alcoholic acid solution (e.g. aqueous ethanolic hydrochloric acid or aqueous methanolic formic acid), treating the eluate with an organic solvent which is a non-solvent for streptin salts (e.g. four volumes of ether or acetone) to cause separation of an aqueous layer containing the streptin salt, and freeze-drying this aqueous solution.  Examples describe the use of culture media containing yeast extract, tryptone, enzymatic digest of milk casein, glycine, or mixtures of any of these materials with starch, and of Long's synthetic medium.

Headings H3B, H3P and H3T. A bi-stable circuit comprises a pair of crosscoupled logic elements of the type in which the logic function can be changed depending on the presence or absence of a control pulse. The elements each receive the same control pulse and complementary information signals and the input to each from the cross-coupling is weighted differently from the control and information inputs. In one embodiment, each logic element comprises a minority transistor circuit, Fig. 3, in which the output D corresponds to the minority of the inputs A, B, C, if P is a logical D, that is D = AB + AC + BC. If on the other hand P is a logical 1, then D=ABC that is the element becomes a NOR circuit. As shown transistor 34 only conducts when a majority of the inputs A, B, C, P are at a negative potential. A pair of such circuits are crosscoupled. Fig. 4, to form a bi-stable store in which two of the inputs to each element are cross-coupled to the output of the other, the input P is common to both, and information inputs R, S are antiphase. With such an arrangement if P is a logical 1 the output D, D 1  are switched in accordance with the values of R, S and if P = O the outputs are independent of R, S. Tunnel diodes, valves or magnetic cores, Fig. 5 (not shown), may be used in the logic elements in place of transistors.
