IPC: D02H3/00
Filed: 1964-09-16
Abstract: A method of setting Axminster spools comprises selecting a yarn 10 from a creel 13 by means of a jacquard operated mechanism 11, winding the yarn on to a storage member 14, repeating the selection and winding for each individual yarn in a weft-wise row of the pattern and then transferring the yarns collectively from the storage member 14 to as many spools 15 as are necessary for each repeat of the row in a pattern or patterns.

A spring 7 may be provided to assist brake engagement, and in other embodiments the pole pieces are L-shaped or comprise a complete ring surrounding the end ring 22. Housed in a shield 14 is a fan 19. Plate 11 or 12 may be peripherally grooved to effect eddy current braking.

Title: Prevention of corrosion of wet metal articles
IPC: C23F11/08
Filed: 1965-03-17
Abstract: In a method for the wet preservation and corrosion protection of a metal article (e.g. of ferrous or cuprous metal) in contact with an aqueous phase, the aqueous phase contains 0.1 to 3000 mg. NH2NH2 per litre of water and 0.1 to 50 mg. methylene blue per litre of water. It may also contain 0.01 to 10 mg. of a complex heavy metal cyanide (calculated as the heavy metal) per litre of water, e.g. an ammonium or alkali metal complex heavy metal cyanide. By heavy metal is meant Cu, Co, Ni, Ag and Fe. The method can be used for preserving steam producing plants, hot water plants, circulating coolers and heat exchangers from water containing oxygen and/or inorganic salts such as the chlorides, sulphates and/or nitrates of the alkali metals and alkaline earth metals. In use, the colour of the solution serves to indicate whether or not excess NH2NH2 is present. The activating effect of methylene blue on the reaction between NH2NH2 and O2 is enhanced by light energy, heating and the catalytic effect of metal surfaces.

Title: Carding machines
IPC: D01G15/32
Filed: 1967-01-26
Abstract: To prevent variation of stress and strain in the frame of carding engine altering the separation of carding rollers or cylinders, at least two of the rollers are mounted in bearings 15 oppositely disposed on beams 10, 11, the beams being supported at their ends so as to permit pivotal movement relative to their support means at each of their ends about horizontal transverse axes. As shown beams 10, 11 are pivoted on pins mounted on U-shaped supports 13, 14. In a further form support 14 is removed, the free end of the beams joined by a web and the web supported centrally by a fulcrum joint. In another form the beams are mounted in bearings for limited rotation about their own longitudinal axes. Some of the carding rollers may be mounted on a subframe pivoted to the main supporting frame or to its supports. Rigid wheel members are mounted on the beams concentric with the main cylinder to provide locating means for the elements associated with the periphery of the cylinder.

Patent ES-346843-A1 (ES)
Title: Hydrodynamic braking devices with hydrostatic safety feature for tractor vehicles with or without trailers
IPC: B60T11/10
Filed: 1967-11-07
Abstract: In a tractor braking system the main source of fluid pressure to friction brake cylinders is a pump P (Fig. 1) driven by the tractor engine, and brake fluid pressure is provided by a pedal operated master cylinder if the pump fails or the engine is stopped. Unilateral braking selector valve.-Two pedals are provided on the tractor operable simultaneously or individually as for unilateral braking. Movement of a pedal, e.g. pedal 7 (Fig. 2) (section through II-II, Fig. 1), moves push rods 11, 13 to the left as shown, rotating against a torsion spring 20 a member 15 on a pin 17 (there being a similar member 16 operable by push rods 12, 14) so that a face 55 thereof is moved away from a rod 22 and a spring 56 closes a selector valve 4 while a rod 21 keeps selector valve 3 open. Thus the right hand brake is isolated and the left hand brake operated as described below. Power pump supplied braking.-On movement of the pedal (or pedals) an abutment 23 thereof engages a push member 25 (Fig. 1) which moves a slide valve 26 to the left. This valve 26 cuts off communication between a groove 48 and a cylinder 51 thus isolating the brakes from the reservoir R and opening up a passage between grooves 48 and 40 of both slide valve 26 and a coaxial slide valve 28 i.e. between the brake cylinders and the pump P. Moreover this movement of valve 26 throttles the passage between groove 40 and groove 41 i.e. between the feed line f 1 from the pump and a fluid outlet line f 2 to hydraulically operated appliances AG, thus causing an increase in pressure in groove 40 and in a pipe line leading to the brake cylinders via a port 49 linked to groove 40. The pressure in groove 40 also propagates via a duct 58 into an annular chamber 59 in which it actuates a differential piston 60 sliding on push member 25 and which contacts slide valve 28 pushing it to the left against a spring 61. The movement of valve 28 adjusts the amount of throttling between grooves 40 and 41 so that a fluid pressure necessary for the desired brake application is obtained. The longer the stroke of valve 26 to the left, the higher the pressure must be in chamber 59 (and therefore in the brake cylinders) for moving the slide valve 28 to its proper throttling position. Master cylinder-safety braking.-In the case of engine stoppage or pump failure, when the pedal (or pedals) is depressed the slide valve 26 acts as an intermediate push member engaging piston 31 of the master cylinder 2 moving the piston against a spring 64. This movement transmitted via a spring 32 and valve 35 will close a port 35 thus isolating the braking circuit of a trailer. Simultaneously pressure will rise in chamber 38 of the master cylinder being transmitted to the brake cylinders via a duct 37, open valves 3, 4 (Fig. 2) and ports 5, 6. Springs 63 are coupled to the brake pedals to enable a driver to "feel" the braking action.

Patent ES-361727-A1 (ES)
Title: A programmed apparatus for the serial handling of numerical information
IPC: G06F7/50
Filed: 1968-12-20
Abstract: Digital electric calculator has a delay line memory 2 connected in a closed loop with a calculator unit 1 containing an adder-subtractor 6 and a shift register 5, the delay line containing numerical words interlaced with corresponding digits of each word adjacent each other, the digits being composed of a predetermined fixed number of bits and the register having an equal number of stages. The delay line shown contains eight registers each holding a twelve-digit binary coded decimal number. The digits pass via an amplifier 3 to a series of switches in the calculator unit. To perform an addition or subtraction on adjacent digits the first digit to be operated on is fed to the shift register. When the first bit of the following digit leaves amplifier 3 it is fed to the adder-subtractor 6. At the same time the first bit of the earlier digit leaves the shift register to enter amplifier 4 and is also fed to the adder-subtractor. The addersubtractor output is at the same time connected to the shift register input so that the sum of the input bits is stored in the shift register. At the end of the arithmetic operation the switches are arranged to feed the data through the shift register. Any corrections required to produce appropriate carries are carried out on the next circulation when a 6 is added to or subtracted from the b.c.d. number via input d where necessary, any carries to the next digit being held in flip-flop 8. If two spaced digits are to be operated on, for instance the digits in the first and fifth registers, then the digit of the first word is passed by the shift register to enter the delay line but when the digit of the second word is in the delay line the remaining words are connected to pass via the unit 6 until the digit of the last word has passed, the second word digit meanwhile recirculating in the shift register and then the second word digit is added to the end of the group containing the corresponding digits. Thus the register digits are in the order 2.6.5.4.3.1. This is repeated until the required digits are adjacent.
