Title: Improvements in or relating to photographic cameras with control of camera members in dependence on film speeds
IPC: G03B7/00
Filed: 1965-04-09
Abstract: A photographic camera, in which insertion of a film cartridge 11 having a control shoulder 11a positioned according to the speed of the film in the cartridge displaces a camera member by means of a transfer linkage comprising a rotatable lever 14 abutting at one end a movable control pin 16, has the other end of the lever 14 bearing a sensing lug 14e which engages a hole in a disc (15) Fig. 2 (not shown), which disc carries pins (17), (18) engaging in slots in diaphragm blades (20), (21). Insertion of a cartridge displaces the pin 16 in the direction A and rotates the lever 14 which in turn rotates the disc (15) a fixed amount. Rotation of the disc causes the diaphragm blades to move to set the diaphragm to a size dependent on the speed of the film. Removal of the cartridge causes the blades to take up their original position in which the diaphragm aperture is at its largest.

Patent ES-346348-A1 (ES)
Title: Hydraulic Pressure Casting Machine.
IPC: B22D17/32
Filed: 1967-10-23
Abstract: The plunger 11 of a pressure casting machine is initially moved by hydraulic pressure fed, via inlet 12, to a pressure chamber 9 of a cylinder 10 and then, in a second stage, the plunger 11 is rapidly accelerated by opening a check valve 5 and allowing the stored pressure energy of an oil-filled, gas pressurized accumulator 1 to act through large cross-section, low flow resistant passages 6, 7 on the said plunger 11. The accumulator 1 is arranged vertically with the valve 5 on its top pressure oil side 2. The valve 5 comprises a movable element 15 spring biased on to a seat 18. An electromagnetic reversible valve 22 is operated to allow the pressure in a chamber 28 of the valve 5 to drop to atmospheric so that the element 15 can be moved against the spring 17 by the pressure in the chamber 9 fed via the inlet 12. The opening of the valve 5 is adjustable by the positioning of a spindle 19.

Patent ES-358841-A1 (ES)
Title: Bistable permanent magnet coupling system
IPC: H02K49/06
Filed: 1968-10-04
Abstract: A switchable permanent magnet system comprises at least one permanet magnet in a magnet circuit having two interruptions, one of which forms a working air-gap, and an armature which can be moved from a first position bridging one of the interruptions to a second position bridging the other interruption by means of a current pulse applied to a winding surrounding the armature. As shown, Fig. 1, a plurality of annularly disposed, alternately poled permanent magnets 2, 3 are provided with upper pole shoes 5, 4 and lower pole members 7, 6 respectively defining upper and lower air-gaps. Coils 10 are located in the spaces 26 between the magnets and surround armatures 9 which are shown bridging the lower air-gaps 8 in which position the magnet is in the "full on" condition. When a current pulse of correct polarity is applied to a coil, poles are generated in the associated armature in such a sense that it is repelled from the lower pole members and attracted to the upper pole pieces to which it moves and bridges thus shunting the magnetic flux from the working air-gap 11 defined between the upper pole pieces and an eddy current brake disc 12. The braking force may therefore be reduced by switching selected armatures to their upper positions and when all the armatures are so disposed the magnet is effectively switched off. If the magnet system is to be rotated in use the armatures are restrained from radial movement due to centrifugal force by connecting their inner ends to link structures by means of hinges, the links extending radially towards the centre of rotation near which they are hinged to the base-plate. The inner and outer ends of each armature may have recesses which partially surround the opposite sides of the coil, Fig. 3 and 4 (not shown). Spring loaded plungers may be located in the upper and lower polepieces to cushion the movement of the armature and to reduce the current required to move the armature, Fig. 5 (not shown). The structure may be used in stationary and rotary magnetic chucks, locking devices, and value controls as well as eddy current and hysteresis brakes and clutches. Additional permanent magnets may be provided bridging the working air-gaps.

Title: Improvements in or relating to digging buckets for a grab, scraper or excavator.
IPC: E02F3/40
Filed: 1969-02-12
Abstract: A digger bucket is formed by a digger teethcarrying, steel base plate 2 that at its rear end is bent back on itself, preferably inwards of itself, to form a box-like, stiffening structure 3. The edge of the bent over part of the plate is welded to the rest of the plate. Each of the side-forming, members of the bucket is a suitably configured plate that is provided with a flange extending at right angles to the plane of the plate. When each side-forming member is assembled with the plate 2 the flanges overlaps the associated side edge of the plate 2 to allow of the welding of the one to the other along spaced welding lines at the edges of the zone of contact therebetween.

Patent ES-367664-A1 (ES)
Title: Plastics materials having electrodeposited metal coatings
IPC: B05D1/34
Filed: 1969-05-26
Abstract: It is known to coat plastics materials, especially thermoplastics such as ABS, with metal by electrodeposition, typically with chromium on top of nickel. Conventional methods are often unsatisfactory when applied to thermosetting resin-based articles, the metal coating peeling or flaking off when the articles are subjected to repeated changes in temperature. It has now been found that copper or nickel coatings adhere well to surfaces, prepared in a conventional manner, of thermosetting plastics as well as of thermoplasts, provided that the coatings are electrodeposited in a manner such that they have an average stress in tension of at least 2,000 kg./sq. cm.

A small amount of partially hydrolysed polyvinyl alcohol may be included as a thickening agent in the polymerization system. The ester monomer (a) may be an alkyl acrylate, methacrylate or chloroacrylate or a vinyl ester of C 2 -C 6 aliphatic monocarboxylic acid. Monomer (b) may be an alkyl acrylate, methacrylate or chloroacrylate or a vinyl ester of an aliphatic monocarboxylic acid. Suitable as acid monomer (c) are acrylic, methacrylic, [alpha]- or #-chloroacrylic, crotonic, isocrotonic, chlorocrotonic and chloroisocrotonic acids. Polyhydric alcohol components specified are C 2 -C 6 aliphatic glycols, N,N,N1,N1 - tetrakis - (2 - hydroxypropyl) ethylenediamine, dipropylene glycol and bis- (4 - hydroxypropoxyphenyl) - dimethylmethane.

Patent ES-377862-A1 (ES)
Title: Filtration apparatus and method
IPC: B01D21/00
Filed: 1970-03-24
Abstract: A pressure filter and a method of filtering of the type employing a particulate filter aid may be operated substantially continuously through an operating cycle composed of a cleaning stage of short duration, say on the order of 4 or 5 seconds, in which the filter aid layer and accumulated filter cake are purged from an open-work, supporting filter element, a coating stage in which a new layer of filter aid is formed on the filter element and involving a time of about 10 seconds, and a filtering stage. A rapid coating of the element with a layer of filter aid is facilitated by using a filter aid having a mean particle size approximately equal to the size of the openings in the support. The filter aid purged from the filter chamber during each cleaning cycle is recovered by conducting the mixture of filter aid, impurities, and raw liquid from the filter, upon cleaning, to a holding tank and then recycling, over a period of time or continuously, the mixture from the holding tank through a separator. The filter aid fraction is separated and conducted into a filter aid storage tank for use during the next cycle, make-up filter aid and filtrate being added to the filter aid storage tank as required. The level in the holding tank is reduced just before each cleaning to the extent required to provide a capacity sufficient to receive the mixture purged from the filter during cleaning. Continuous filtrate output may be achieved by accumulating filtrate in a storage reservoir during the filtering stage (for delivery) during the cleaning and filter aid coating stages.
