A process for developing a gelatino-silver halide light-sensitive element including an aldehyde pre-hardening step before development, comprises processing the light-sensitive element between pre-hardening and development in an aqueous solution containing an aromatic primary amino compound represented by the general formula I: wherein A represents SO 3 M, COOM, or NHR (wherein M represents a hydrogen atom, an alkali metal or an animonium group, and R represents a hydrogen atom, an alkyl group, or an aryl group), and B and C each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxyl group, a halogen atom, a hydroxyl group, COOM, or SO 3 M (wherein M is as defined above). The aromatic primary amino compound of the formula I may be 2-aminobenzoic acid, 3-aminobenzoic acid, p-aminosalicyclic acid, p-aminodiphenylamine, sulphanilic acid, metanilic acid, 2-animotolutene-4-sulphonic acid, or aniline -2, 4-disulphonic acid. The compound of the formula I is usually used in a concentration of 0À1 to 50g per litre of the aqueous solution to remove the aldehyde remaining from the pre-hardening step, so that fogging due to the presence of an aldehyde in a subsequent processing step is effectively prevented.

Abstract: 1,199,335. Electrolytically aluminiding metals. GENERAL ELECTRIC CO. Oct. 25, 1967 [Nov. 10, 1966], No.48516/67. Heading C7B. A method of forming an aluminide coating on a metal composition, the latter having a melting point of greater than 600‹ C., at least 50 mole percent of said metal composition being at least one of the metals selected from the class consisting of metals whose atomic numbers are 23 to 29, 41 to 47 and 73 to 79 inclusive, which method comprises (1) forming an electric cell containing said metal composition as the cathode, joined through an external electrical circuit to an aluminium anode or an anode of an alloy having aluminium as its most electro-positive component and a fused salt electrolyte consisting of (a) one or more of the alkali metal fluorides or a mixture of one or more of the alkali metal fluorides with one or more of the fluorides of calcium, strontium and barium and, (b) from 0À01-5 mole percent of aluminium fluoride, said electrolyte being maintained at a temperature of at least 600‹ C. but below the melting point of said metal composition in the substantial absence of oxygen and (when said metal composition includes a metal of atomic number 23, 24, 41, 42, 73 or 74) in the absence of carbon contacting the electrolyte and (2) controlling the current flowing in said electric cell so that the current density of the cathode is in the range from 0À05 to 10 amperes/dm<SP>2</SP> during the formation of the aluminiding coating. The term "aluminide" designates any solid solution or alloy or intermetallic compound of Al and the base metal. The cell generates electric current. The deposition rate of the Al may be decreased by inserting some resistance in the circuit or may be increased by impressing a voltage, e.g. to obtain constant current densities during the reaction. Specified fluorides that may be used are those of Li, Na, K, Rb and Cs, e.g. a eutectic mixture of NaF and LiF or of KF and LiF. The process may be carried out under vacuum or an inert atmosphere, e.g. of forming gas (10% H 2 , 90% N 2 ), N 2 , Ar, He, Ne, Kr or Xe. The electrolyte may be purified, e.g. from carbon, by an initial electrolysis. The anode may be an Al-Ni alloy rod, an aluminided Ni strip or be liquid Al in a graphite basket which has been shielded by a woven (Registered Trade Mark) "Monel" screen to prevent carbon from contaminating the fused salt bath. The aluminide has a hard, wearresistant surface. The method is modified for forming an aluminide coating on a metal composition selected from the class consisting of Ti, Zr, Hf (atomic numbers 22, 40, 72) and alloys thereof wherein at least 50 mole per cent of the alloy is Ti, Zr or Hf. The electrolyte is treated to remove carbon and oxygen and a negative potential of 0À1 to 5À0 volts is applied to the cathode prior to and during immersion of the cathode in the electrolyte to complete the electrical circuit.

By altering the radiation used for exposure by a filter the photographic sign of the images formed on the electrodes may be altered. The images may be transferred from the electrodes to a receiving sheet. The invention also relates to an apparatus for carrying out the above process.

A mine-roof support comprises a canopy 16, Fig. 1, which is pressed upwardly by a plurality of pairs of hydraulic props or legs 15 that are capable of restricted pivotal-movement relative to the canopy and a pair of base units 10, 11, backward horizontal-movement of the canopy relative to said units e.g. during advancement of the support, being prevented by a hydraulic pulling-jack, or ram, 19 pivotally attached at one end to a bracket 21 on the canopy and at the other end to a bracket 20 on the unit 10. The jack may be controlled automatically by a valve 25, which is actuated by one of the hindmost legs when the canopy is displaced in a backward direction, opening of said valve causing the jack to exert a tensile force on the bracket 21. Alternatively, or additionally, the jack 19 is controlled by general-control valve-gear 26 for the support. As another alternative, the valve 25 is dispensed with and the jack 19 connected hydraulically to the pulling side of a ram 22 for advancing the support so that the legs 15 are automatically biassed forwardly during advancement. A conveyor C is attached to one end of the ram 22, as shown. In a second embodiment, Fig. 2, the leading end of the canopy is supported by a pair of raked hydraulic-legs 28 and the jack 19 is controlled by valves 32, 33 that are actuated by one of a further pair of hydraulic legs 29, these valves causing the jack to either push or pull so as to oppose forward or backward horizontal movement of the canopy relative to a base unit 27.

To prevent head-switching surges from producing spurious outputs or accidental erasure of stored information, both clamps may be operated with an overlap period corresponding to the duration of head-selection. One read and one write lead are common to their respective sets of windings and transistor switches (Fig. 1, not shown) isolate unselected windings from a ground connection.
