Title: Process for the dyeing of synthetic polyamides in bulk
IPC: C09B45/16
Filed: 1970-04-28
Abstract: Polyamides P are bulk-dyed with C a 1 : 1-Cr complex of D a monazo dyestuff containing at least one -SO 3 H gp. or salt thereof. D may be an o-carboxy-o1-oxy- or an o,o1-dioxymonazo dyestuff, or a pyrazolene or naphthol dyestuff. Dyestuff D may carry substituents not inducing solubility in water, e.g. alkyl, halogen, CH 3 -SO 2 -, -NO 2 , or acylamino. Other exemplified substituents are CH 3 -NH-SO 2 - and CH 3 -O-. D may be where R is a naphthyl residue containing -OH vicinal to the azo bridge, or an o-carboxy or o-hydroxybenzene residue which may contain a Cl atom or a further -SO 3 H gp. m and n are each 1 or 2 or D may be o-hydroxybenzeneazo-#-naphthol. Complex C may be incorporated with the monomers or prepolymers during polymerization to P or by pressing into the melt during spinning. C may be applied to chips of polyamide P which are then melted and spun into filaments or converted to solid articles. The P chips may be tumbled, e.g. with a solution of C in a volatile solvent, e.g. water or alcohol or with a dispersion formed by grinding C with water and a finely-dispersed polyamide. The P chips may be dyed in a bath containing an aqueous solution or dispersion of C, e.g. under superatmospheric pressure and at 130 C., the dispersion may be stabilized with a dispersant. Acetic or formic acid, or ammonium or sodium acetate or primary sodium phosphate may be added to the bath to increase rate of absorption of complex C. Dye bath treatment may be performed on chips of polyamide P in which a pigment has been incorporated during polymerization. 1-2 C in 4-250 parts water may be used per 100 parts P. P may be nylon 6 or 6,6. Articles include injection moulded zipp fasteners and telephone receivers.

Title: Fuel pumping apparatus
IPC: F02D1/18
Filed: 1976-12-06
Abstract: A fuel pump includes a member movable angularly to determine three fuel settings when the pump is used to supply fuel to a supercharged internal combustion engine. The member is moved by a fluid pressure operable means which includes a piston connected to the further member by a pin and a sleeve in which the piston is mounted and which itself is slidable within a cylinder. Fluid under pressure can be admitted to the cylinder by way of a valve, the pressure of fluid depending upon the speed at which the apparatus is driven. A spring is provided to bias the piston and sleeve so that the further member assumes a first position. When fluid pressure is applied the sleeve and piston move the further member to a second position after which further movement of the sleeve is halted so that the pressure in the cylinder must rise appreciably before the piston alone can move the further member to its third position.

Patent ES-476356-A1 (ES)
Title: A process for recovering acid chlorides.
IPC: C07D333/24
Filed: 1978-12-27
Abstract: Chlorination of an acid with a chlorinating agent produces a reation mixture from which the desired acid chloride may be recovered by distillation. In the chlorination and distillation, by-products, polymers and degradation products may be produced which can cause a decrease in the yield of the desired acid chloride. A particular problem arises from the tendency of acid chlorides to degrade and/or polymerize when subjected to excessive temperatures for long periods. An improved process for recovering an acid chloride from a mixture containing the acid consists in distilling the acid chloride from the mixture in the presence of an effective quantity of a distillation improvement additive, Such as an organo polysiloxane or a mineral oil, which remains substantially liquid under the conditions of distillation. In this way the problems referred to are reduced or overcome and increased yields of acid chloride are obtained.

Patent ES-8206899-A1 (ES)
Title: Drive device for an alternately reeling and unreeling recording tape.
IPC: G11B15/44
Filed: 1981-08-28
Abstract: An automatic reverse system for magnetic tape cassette equipment having two capstans with associated pressure rollers and two drivable winding mandrels for the cassette reels. The direction of operation of the apparatus is reversed simply in that the drive motor is electrically switched from one direction of rotation to the opposite direction of rotation. Owing to this change of the direction of rotation a swing arm is changed over, which switches the drive mechanism from one winding mandrel to the other winding mandrel. The winding mandrel now driven in turn linearly moves a control plate, the plate pivots a lever transmission which in turn moves a head support, (via) having stops which lift the pressure roller off the one capstan and permit the other pressure roller to be applied to the other capstan.
Patent ES-8302300-A1 (ES)
Title: Dial and pointer electrical instrument.
IPC: G01D11/26
Filed: 1981-08-28
Abstract: In order to allow a wide range of instruments to be assembled from standard modules, there is provided a range of different diameter housings with their glasses spun in and sealed by an O-ring. A housing can be trimmed to length as required. Different types of panel mountings can be fixed over the front rim of the housing. One of a range of standard movements is mounted between plates and matched to the housing diameter and retained therein by releasable catches. The catches may be turnbuttons cooperating with pegs projecting inside the housing. Alternatively, leaf spring catches slidable radially outwardly on the plate can engage in an annular groove inside the housing and be locked in position by clamp screws. The rear end of the housing is plugged by an O-ring sealed base which carries either a terminal part/connector structure only or also a range scaling circuit enabling the same movement to handle different input signal ranges. The pointer on an offset arm sweeps over a scale which can be hub lit. For small instruments where cylindrical space available radially inside the arm is small, bulbs are mounted in a radially offset position (where the needle does not sweep) of a transparent body to direct light radially inwardly to a 45 DEG surface where internal reflection directs the light axially along a cylindrical lens part from which the light diffuses radially over the scale. Alternatively, the 45 DEG surface can be omitted by locating the bulbs close to the axis in a recess through which the bulbs can be withdrawn in the radial direction.
