Title: Improvements in or relating to intensifying metal nuclear images
IPC: G03C1/62
Filed: 1963-09-12
Abstract: An acid-reacting physical developer for latent metal nuclear images comprises an ionic surface active compound, more than 0À006 mols/litre of a silver compound, more than 0À05 mols/litre of a ferrous compound and a ferric compound in such concentration that the activity and/or life of the developer is increased compared with a reference developer of the composition: - 0À05 mols/litre of ferrous sulphate, 0À005 mols/litre of ferric nitrate, 0À14 mols/litre of citric acid, 0À006 mols/litre of silver nitrate and the same surface active compound in the same amount the activity and life of the developer being at least equal to the reference developer. The ferrous compound may be ferrous sulphate or ferrous ammonium sulphate and the ferric compound may be ferric nitrate. The developers may comprise citric, oxalic, malonic, tartaric or lactic acid or ethylene diamine tetracetic acid. When certain acids are present (such as citric or oxalic acids) which reduce ferric compounds to ferrous compounds in ultraviolet light, the developer may be compounded with excess ferric compound but no ferrous compound, and then exposed to ultraviolet radiation before use to give a developer according to the invention. The developer may contain a thickening agent such as gum tragacanth and be applied as a paste to the image to be developed. When the metal nuclear image is obtained in a secondary reaction, e. g. by treating an exposed sheet, sensitized with an aqueous solution of o-methoxy-benzene diazosulphonate and cadmium lactate, with an aqueous solution of mercurous nitrate and silver nitrate, the mercurous nitrate may be incorporated into the developer according to the invention and both the secondary treatment and physical development effected in a single step.

Title: Improvements in or relating to a coffin consisting of substantially imperishable reinforced stiff synthetic resin material
IPC: A61G17/00
Filed: 1963-10-24
Abstract: A coffin is made of a stiff synthetic resin which resists natural decomposition (e.g. polythene or polyvinyl chloride) and which is reinforced there being in the coffin walls through-holes (8) plugged by members 7 which are less resistant to decay than the synthetic resin. The synthetic resin is reinforced by a reticulated structure of wires or metal rods and the holes (8) are threaded with rope 7 or plugged by wooden dowels (not shown). The coffin cover 2 has a peripheral flange 2a which abuts a peripheral flange 1a around the top of the coffin body 1, the flanges being secured together by complementary groove and tongue parts (1b 2b), a jointing compound and screws (5).
Patent ES-293419-A1 (ES)
Title: Improvements relating to master cylinders of hydraulic braking systems
IPC: B60T11/232
Filed: 1963-11-02
Abstract: A master cylinder comprises a main piston 1, a control piston 2 behind the main piston normally defining a space 15, and a duct 7, 10 formed partly in the control piston and partly in the main piston establishing communication under certain conditions between a replenishment reservoir (not shown) and a pressure chamber formed ahead of the main piston, said control piston carrying a check valve having a free ball valve member 5 which is seated by the dynamic action of the fluid when braking pressure is produced in the pressure chamber. On initial depression of the brake pedal, the control piston moves rightwards until the resilient ring 4 thereon engages the main piston to out off the space 15 from the duct 10. On further control piston movement, the pistons abut and move together, the resultant pressurization of the pressure chamber washing the valve member on to its seat to prevent communication between said chamber and the reservoir via connection 13, axial passages 9 in the piston peripheries and duct portions 7 and 10. On pedal release the pistons are moved back in unison by spring 14. Should suction develope downstream of the valve, ball 5 unseats to re-establish communication with the reservoir. Finally, the main piston flange 12 engages a stop formed by the connection nipple 13 and the pistons separate. The valve seat 6 comprises a resilient ring which deforms when compression exceeds a given value to allow the ball to engage the bevelled end of the duct 7.

The support 14 is thus angularly adjustable about the bolts 20, and adjustable as to height by inserting the bolts 8, 20 in different holes 14 4 , 6 2 . The oblique arms 6 are angularly adjustable about the axis 7 by being secured to the pillar 1 by a bolt 24 extending either through a hole B or through arcuate slots (not shown) centred on the axis 7 and extending between A and B. The arms 4, 6 are of thin iron sheet of L-section, the pillar 1 is of iron sheet of U- section, concave to the rear, and the support 14 may be of thick metal plate or may be moulded. A luggage carrier 22 is supported by two arms 23 and by the bolt 24 or 8, and supports a mudguard 25 also supported by spacing sleeves (26), Fig. 2 (not shown) on the bolt 8, and between the flanges 14 1 and the pillar 1.
Patent ES-311908-A1 (ES)
Title: Improvements in or relating to machines for labelling objects and especially bottles
IPC: B65C3/14
Filed: 1965-04-15
Abstract: A machine for applying body and neck labels to bottles comprises a continuously rotating label distributer which moves at the same speed as the bottles are conveyed and applies the labels while they are held against rotation. The label distributer 15 has label suction units 23 and holding members 34, 341 with an interposed pressing member 35 mounted on constantly rotating chains so that the units 23 extract a label from a magazine 9 pass it over a gumming roller 8 to the application position. Bottles B fed by a conveyer 4 are spaced by a screw 5 and then held between the members 34, 341 and members 38, 381 of a second carriage 37 all of which are travelling at the same speed as the conveyer 4 so that the labels are accurately applied by the pressers 35. Application is completed by brushes 40, 401 the bottles being rotated as they enter and leave due to the conveyer belts 39 being longer than the belts 391 thus pressing the bottles against wads 41, 411. A neck label applicator, also having a suction nozzle, is pivoted forward, to contact the gumming roll 8 and to effect application, by cams. To prevent gumming the nozzle when a label is absent the pivoting cam co-operates with a stud controlled by the reduction of pressure due to a label being held on the nozzle. The magazine 9 is pivoted about a shaft 14 towards the units 23 for label extraction by a cam 10 while the box is moved in the directions f 1, f 2 by a cam 11. A weight in a damping fluid holds a plate 57 against the labels but the pressure is released as the magazine reaches the extraction position.

Title: Process for the separation of solids from a suspension thereof in water by means of agglomeration
IPC: C09C1/58
Filed: 1969-06-16
Abstract: Water containing suspended soot is fed via inlet 4 into the space between a cylindrical casing 1 and a rotating cylinder 2 to which is fixed an agitator 3. An agglomerating agent, e.g. a heavy oil, is added through a inlet 5. Water and agglomerated impurities flow past a baffle 6, which ensures that some of the agglomerated impurities are always present in the space between casing 1 and cylinder 2, through an outlet 7 and onto a filter 8 from which separated impurities flow through a discharge 10, e.g. a tube or gutter, and water flows through a discharge 9. The concentration of suspended impurities in the discharged water is measured by a photometric device 12 and compared with an arbitrary valve by a device 13 the output of which actuates a device 14 incorporating a timing mechanism to regulate the flow of agglomerating agent through a valve 15. If the concentration of suspended impurities exceeds the set value, discharged water may be recirculated. The rotatable cylinder may have a hollow portion (25), Fig. 3 (not shown), having vanes (26) and slits (27) through which the water and agglomerated impurities pass into an apertured tube (28) and into a compartment (30) of the casing (23) formed by a partition (29). Agglomerated impurities may be discharged from the space between the rotatable cylinder and the casing (23) through an outlet (32).
