Patent ES-352628-A1 (ES)
Title: Improvements relating to heat exchangers
IPC: F28F1/32
Filed: 1968-04-10
Abstract: A heat exchanger e.g. for a motor vehicle comprises a number of pipes seamed longitudinally and a number of cooling fins or ribs soldered to the pipes by a coating of solder provided on each fin or rib prior to assembly of the exchanger, only at the connection area of each fin or rib. In an embodiment flat pipes seamed at 6 are arranged between corrugated fins 2 provided with solder, by dipping, only on the bends 3, 4 and the assembly is heated in an oven to melt the solder and join the fins to the pipes at 5. The end edges of the fins are sealed during the application of solder to the bends. In a modification flat cooling ribs are provided with tapered solder coated sleeves about apertures therein, and flat longitudinally seamed pipes are passed through the sleeves to be soldered therein when the assembly is heated in an oven. The known methods of, (a) providing tinned pipes with cooling ribs and heating to melt the tinning which solders the seams of the pipes and solders the pipes to the ribs and (b) providing tinned ribs on welded pipes and heating to effect the soldering of the ribs to the pipes by the melted tinning are referred to.

Title: Flexible hulls
IPC: B60V1/00
Filed: 1968-06-21
Abstract: In a plenum chamber air cushion vehicle wherein the cushion is enclosed by a flexible skirt composed of an upper inflatable chamber extended downwardly by contiguous looped finger elements vibrations in the skirt assembly are reduced and good over-wave performance and stability is ensured by inflating the upper chamber to a pressure between 1À15 and 5 times the cushion pressure. Additionally, when the chamber is formed by an inflatable looped skirt the distance between the fixing points of the loop to the body must be greater than 0À9 times the vertical distance between the underside of the rigid structure and the lower tip of the skirt assembly. The vehicle has a rigid structure 2 to which is attached along the bow and sides an inflatable bag skirt 1 with depending finger elements 3 contiguously arranged along its lower surface, the portion 1 being sub-divided along its length into compartments 7 by partitions 6. Whereas the attachment points 4, 5 of portion 1 are at a fixed spacing, the pressure in the bag is made variable by connecting each compartment 7 to a variable volume accumulator 8. Each compartment 7, or combination of compartments, and its associated accumulator 8 is supplied with pressure air from a source of supply separate from that which supplies the cushion 12 so that the ratio between the chamber pressure and cushion pressure is maintained at the specified ratio by control means, not shown, An effect of variation of the pressure in the compartments 7 is to vary the area of the cushion 12. The rear end of the cushion is closed by a bag-skirt 14 or other closure means and when it is desired to operate the vehicle as a displacement vessel the bow skirt and the skirt 14 are retracted and the side compartments are inflated to a relatively high pressure to act as catamaran floats.

Title: Spreading implements
IPC: A01C17/00
Filed: 1968-06-15
Abstract: A spreading implement comprises a frame 1, a hopper 25, a member 45 for spreading the material contained in the hopper and a agitator 49 in the hopper wherein the frame 1 includes a portion afforded by a plate which supports hopper, the plate consisting of an upwardly extending portion 15 secured to the frame 1 and upper 14 and lower 13 portions which are connected to the hopper and a bearing 34 respectively, the bearing carrying a shaft 38 which carries the spreading member. The base of the hopper is afforded by an outlet plate 57 which is attached to a sealing ring 28 attached to the lowermost edge 27 of the outlet portion of the hopper. The outlet plate contains two apertures which co-operate with two apertures in a control member 67, the outlet plate and the control member being rotatable relative to the frame and to each other by means of the strip .61, which may be held in the desired position to control the general direction in which material is spread by means of a spring loaded pin 63 which co-operates with apertures in the plate 64, and the strip 70 respectively. The strip 70 is attached to the strip 61 by means of the tension spring 71 which urges the strip 70 towards the strip 61, the holes in the outlet plate and the control member being aligned when the two strips 61 and 70 abut. A sliding stop 73 may be clamped to the plate 66 by means of the wing nut 74 to limit the movement of the strip 70 and thereby limiting the degree to which the holes in the plate 57 and the member 67 co-operate. The outlets from the hopper may be closed during operation of the spreader by means of the rod 76 which is mounted in a slot in the bracket 78. The slot tapers in a downward direction so that the rod 76 may be held in any desired position by wedging it in the narrow part of the slot. The whole implement may be mounted on a tractor three point hitch by means of the pins 9,10 and the aperture 12 and may when not in use be supported on the ground by the frame member 20. A further bracket 23 is provided for attaching a further vehicle, e.g. a container vehicle, for the material to be spread.
Patent ES-367112-A1 (ES)
Title: Preparation of 1-propynyl phosphoric acid and salts thereof
IPC: C07F9/38
Filed: 1969-05-12
Abstract: A salt of 1-propynyl phosphonic acid is prepared by treating a mono- or diester of the formula or mixture thereof with a base, R being a straight or branched chain alkenyl or alkynyl group having 2 to 7 carbon atoms or a substituted or unsubstituted monocyclic aryl group and R1 is hydrogen or is a group as defined for R. Preferably R and R1 are 2-propynyl groups. The treatment is usually effected by contacting the ester in a solvent with the base for sufficient time to cleave the ester. The base used may be a strong inorganic or organic base, e.g. an alkali or alkaline earth metal oxide or hydroxide, a basic quaternary ammonium type anion exchange resin, triethylamine, trimethylamine, triethanolamine, an N-alkylpiperidine or tetramethyl ammonium hydroxide. The salts may be converted to the free 1-propynyl phosphonic acid by treating with a mineral acid, e.g. HCl or H 2 SO 4 . Suitable solvents for the main reaction include water, alcohols, dimethylsulphoxide, N,N1-dimethyl formamide and sulpholane or an excess of the base (when appropriate) may be used as solvent. The sodium salt of 1-propynyl phosphonic acid may be converted to the sodium salt of cispropenyl phosphonic acid by hydrogenation and the cis-propenylp hosphonicac id may be oxidized with H 2 O 2 to form racemic cis-1,2-epoxypropyl phosphonic acid which may be recovered as the sodium salt and the latter treated with quinine in methanol to yield the quinine salt of (-) (cis- 1,2-epoxypropyl) phosphonic acid which is then converted to the ammonium salt by treating with NH 4 OH in water, details being given for each step of the process. The (-) (cis- 1,2-epoxypropyl) phosphonic acid is an antimicrobial agent and may be administered orally e.g. in the form of its Na, K or Ca salt, or parenterally. Also, salts of (+) (cis-1,2-epoxypropyl) phosphonic acid inhibit undesirable bacterial growth in the white water used in paper mills, or in paints e.g. polyvinyl acetate latex paint.

Title: Carburettor slow running jet control - has solenoid valve to close orifice when engine is braking vehicle
IPC: F02M3/045
Filed: 1977-03-30
Abstract: The carburettor of a vehicle engine has a solenoid operated valve (1') in the fuel passage to the slow running jet. The solenoid can be energised by a contact (6') operated by the accelerator pedal. A parallel circuit energises it through a relay (8') which is normally closed and is opened by a tachometer (9') when the engine speed exceeds a preset minimum. At low speed, the valve is kept open by the tachometer. At high speed it closes if the accelerator is released to slow the vehicle down. The system thus shuts theslow running jet when the engine is braking the vehicle. A manual switch (7') can keep the valve permanently open.

Title: Collector installation for solar energy - has skeletal structure with rows of adjustable reflectors focussed on common absorbers
IPC: F24S23/74
Filed: 1978-08-04
Abstract: The complicated and expensive erection work connected with the assembly of a large number of collectors for the energy of the sun, esp. e.g. the large number of pipe joints necessary, is simplified and reduced considerably. A collector platform formed from light structural details is set up, inclined to the vertical and free to rotate on a vertical axis. In this the reflectors are arranged in rows side by side the focussing line of the reflectors in one row lying in a straight line, in the proximity of which a common absorber for the row is positioned. The row of reflectors thus forms a long parabolic mirror with a length which is the multiple of a single mirror and instead of separate abosrobent tubes, one long tube can be used.
Patent ES-474243-A1 (ES)
Title: Improvements in or relating to valve assemblies and power assisted steering systems.
IPC: F16K11/07
Filed: 1978-10-16
Abstract: A flow divider valve assembly and a power assisted steering system therewith. A spool (1) is axially slidable in a spool cylinder (2) within which it is biased (23, 24) to a neutral condition in which two control ports (13, 16) are open. A first of the control ports (13) is in a first fluid line which extends from an inlet port (8) by way of a first auxilliary chamber (11) to an outlet port (15) and the second control port (16) is in a second fluid line which extends from the inlet port (8) by way of a second auxilliary chamber (12) to a second outlet port (18). The outlet ports (15, 18) can be connected to opposite sides of a power assisting ram in a steering system. Communicating with the first fluid line downstream of the first control port (13) is a first primary chamber (19) formed on one side of the spool (1) and communicating with the second fluid line downstream of the second control port (16) is a second primary chamber (21) formed on the opposite side of the spool (1). The control ports (13, 16) are controlled by the spool (1) so that if fluid flow is resisted at one of the outlet ports (15, 18) fluid pressure develops in the primary (19, 21) and secondary (11, 12) chambers associated with that fluid line to subject the spool (1) to a pressure differential which causes it to be displaced axially from its neutral condition in a sense which progressively closes the control port (16, 13) of the other fluid line.

Patent ES-479295-A1 (ES)
Title: Pedal control for an infinitely variable gearing of a vehicle.
IPC: G05G1/30
Filed: 1979-04-04
Abstract: A control assembly is for use in a vehicle having a transmission with an output shaft whose speed and direction are continuously adjustable by means of a selector rod. A pedal is movable in one direction from a rest position and a switchable mechanism connects the selector rod with the pedal. In a first condition when the pedal is depressed, the switchable mechanism causes the selector rod to move in one direction from a central position in which the output shaft does not rotate. This in turn causes the output shaft to rotate in one direction. When the switchable mechanism is shifted to a second condition, depressing the pedal causes the selector rod to move in the opposite direction from its central position, and this causes the output shaft to rotate in the opposite direction. Shifting of the switchable mechanism from one condition to another is effected by a solenoid which is controlled by a circuit. The circuit includes a selector switch for actuating the solenoid to cause the switchable mechanism to change conditions, and the selector switch may be actuated at any position of the pedal. The circuitry, however, enables the switchable mechanism to be changed from one condition to the other only when the selector rod is in its central position.
Patent ES-8100088-A1 (ES)
Title: Toy with spring-operated speed regulated motor mechanism
IPC: A63H17/12
