Abstract: 984,157. Photographic development. EASTMAN KODAK CO. Oct. 12,1962 [Oct. 16, 1961], No. 38669/62. Heading G2C. An exposed photographic silver halide layer is developed by contacting it with a metal in the presence of a developing agent and a sequestering agent so that the hydroxyl ions generated by the action of the sequestering agent on the metal will raise the pH to a sufficiently high level for development to take place. Metals specified are magnesium, zinc, cadmium, aluminium, indium and gallium and their alloys. The sequestering agent may be citric, tartaric, ascorbic, aspartic, ethylene diamine tetra-acetic, 1,3-diamino-2-propanol tetra-acetic or 1, 2-diamino-cyclohexyl-N, N-tetraacetic acid or an alkali metal salt thereof. The exposed emulsion may be bathed in a solution of the developing agent and the sequestering agent at a pH too low to effect development, and then contacted with a metal plate or roller. Alternatively, the developer may be incorporated in the emulsion. In another embodiment, a hollow cylinder of cellular magnesium containing a solution of the developing agent on the sequestering agent is drawn across the exposed emulsion layer which contains the other reagent. In a further embodiment, the powdered metal such as zinc is mixed with a binder such as gelatin and coated on a paper support. This is soaked in a solution of the developing and sequestering agents and placed in contact with an exposed silver halide layer. Silver halide solvents may be added to the solutions applied to the silver halide layers to effect simultaneous developing and fixing.

Abstract: 1526526 Fluid shattering of rock; blasting ATLAS COPCO AB 20 Sept 1976 [19 Sept 1975] 38915/76 Heading E1F [Also in Divisions B5 and F3] A method of breaking a hard compact material, e.g. in situ rock, in which at least one hole is pre-drilled comprises maintaining a column of relatively uncompressible fluid 12, e.g. water, having a length which exceeds the hole depth, filling the free cross section area of the hole with fluid at the one end of the column which directly contacts a surface of the hole, maintaining the other end of the column free, generating a shock wave in the column outside the hole, and transmitting a shock wave through the column into the hole to act directly on a surface of the hole, the shock wave having a sufficient amplitude to cause cracks to form in the material. Preferably the column has no sudden substantial changes of cross sectional area or direction which could cause substantial shock wave energy losses. The shock wave is generated by accelerating an impact body, e.g. a solid piston 11 or a fluid piston, towards the fluid column to impinge on the free or outer end of the column, which is contained in a tube preferably a flexible hose, which is entered into the hole and which serves as a wave guide to the shock wave generated in the fluid column.

Abstract: 1411868 Automatic control of weight or flow WERNER & PFLEIDERER 21 Aug 1973 [8 Sept 1972] 39469/73 Heading G3R In apparatus, in which continuous strip 5 e.g. rubber is intermittently fed into the apparatus, cut into sections 4 and conveyed on conveying means 1 to a processing station 11, weight of the cut sections conveyed by the conveying means per unit time is controlled to a desired value. As shown, a counter 13 counts up at the frequency of a signal generator 20 whilst a section passes an electronic sensor 12, after which the count is reversed, a cutting command sent to cutter 3 and a pneumatically controlled barrier 8 lowered. The reverse count is at a frequency determined by a voltage to frequency converter 14 fed from comparator 15 that compares a required throughput set at 16 with the conveyer loading measured at 1. The duration of the reverse count determines the time that barrier 8 is lowered i.e. the spacing between adjacent cut sections. This spacing is varied to maintain the loading on the conveyer constant, and, since the conveyer speed is also constant, this maintains the throughput to the processing machine at the desired value. In an alternative, Fig. 2 (not shown) the throughput is regulated by varying the conveyer speed according to the comparison of the required throughput and the actual throughput calculated from the measured belt loading and speed, the barrier being operated so as to maintain equal spacing between sections.

The compounds wherein X is a halogen in each case may be prepared in four ways: a Á, (Á<SP>1</SP> - dihalotetranitrosyldiiron may be reacted with a compound of the formula in an inert solvent for at least one hour under an inert atmosphere and is then filtered to give a solution from which the product may be crystallized; the Á,Á<SP>1</SP> - dihalotetranitrosyl. diiron may be reacted under similar conditions with the allyl or substituted allyl halide and either metallic tin, lead or germanium or the metal dihalide and a reducing agent; or the Roussin's black salt KFe 4 S 3 (NO) 7 , or Roussin's red salt, Fe(NO) 2 SEt may be reacted under an inert atmosphere with cadmium halide, a tetraallyl tin, lead or germanium compound and a reducing agent. The compounds wherein one X is a hydrocarbon radical may be prepared by treating the dihalogen compounds prepared as above with a hydrocarbyl magnesium halide or alkali metal, alkali earth metal or aluminium compound. Both the compounds themselves and their solutions are somewhat unstable although the solid compounds show greater stability. The compounds of the invention, either as the solutions formed as above or as crystallized solid may be used to catalyse homo- and codimerization of acyclic conjugated dienes by stirring the reagents and catalyst together at a suitable temperature. Thus buta-1,3-diene may be homodimerized to 4 - vinylcyclohexene by heating at 40 C. for 2 hours with a benzenetetrahydrofuran solution of bis(# - allydinitrosyldiiron) tin dichloride.
