Abstract: A liquid detergent composition having a pH of 4-7 suitable for the treatment of natural fibres contains 0.1-80% by weight of a detergent, a water miscible organic solvent, and an electrolyte, the relative proportions of the electrolyte and the organic solvent being such that the composition comprises two aqueous layers at 0 C. The liquid composition may contain up to 90% by weight of the organic solvent, preferably 2-40% by weight. The amount of electrolyte is preferably 3-25% by weight of the composition and the amount of the detergent is preferably 5-30% by weight of the composition. The relative proportions of the constituents of the liquid composition are ideally chosen such that the weight of the lower aqueous layer is between 2 and 75% by weight of the composition. The electrolyte preferably forms part of a buffering system. The watermiscible organic solvent may be a straight or branched chain monohydric aliphatic alcohol (C 1-7 ), e.g. ethyl alcohol a dihydric aliphatic alcohol (C 2-7 ), e.g. hexylene glycol a monoalkyl ether of an aliphatic dihydric alcohol (C 3-6 ), e.g. the monomethyl ether of ethylene glycol a dialkyl ketone (C 3-5 ), e.g. acetone or benzyl alcohol or phenyl ethyl alcohol. Among the anionic constituents of the electrolytes may be used lactic acid, citric acid, tartaric acid, ascorbic acid, salicylic acid, phosphoric acid, ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriamine penta-acetic acid, 2- hydroxyethyliminodiacetic acid, sorbic acid, glycollic acid, and mixtures of these acids. The cationic constituents may be sodium, potassium, lithium, ammonium, and alkanolamines. Mixtures of salts may be used but it is preferable to use electrolytes other than those with solely mineral cations, e.g. sodium citrate, since these may lead to crystallisation. The detergent may be a conventional anionic, ampholytic, cationic or non-ionic detergent. The liquid composition may also comprise a layer of a liquid, water, immiscible, oily material, e.g. a silicone oil, vegetable, animal or mineral oil, the weight percentage of the oily material being up to 50% of the composition. In addition the composition may comprise foam improvers and stabilisers such as tertiary amine oxides, betaines and higher fatty acid alkanolamides perfumes colouring agents preservatives protein hydrolysates antioxidants germicides and pigments. When colouring agents are used, the liquid composition has two or more layers of different colour.
Patent ES-362938-A1 (ES)
Title: Coin tester with slotted coin guide duct
IPC: G07D/
Filed: 1969-01-25
Abstract: A coin tester comprises a longitudinallyslotted coin shoot 1 surrounded by an induction coil 3 of an oscillator circuit 5 whose signal is temporarily changed by the passage of a coin, such that the acceptance of the coin depends on the change of signal. The tester identifies two different coin denominations, using two coils 3 and 4, connected to oscillators 5 and 6, and monostable multivibrators 9 and 10, respectively. Passage of a correct coin causes the corresponding oscillator to stop oscillating, whereupon its multivibrator supplies an extended pulse. The pulse from multivibrator 9 continues until the coin has passed coil 4, and the pulse from multivibrator 10 has at least twice that length. The former pulse blocks an inhibit gate 12, and is also differentiated at 14 and inverted at 15 so that the peak occurring at the end of the pulse reaches an inhibit gate 17 after the coin has passed coil 4. If gate 17 has not been blocked by the coin having stopped the oscillator 6 oscillating as well as the oscillator 5 the peak passes the gate to signal coin acceptance. When oscillator 6 is stopped oscillating it sends an accept signal through gate 12, unless it has been blocked by the coin stopping the oscillations of oscillator 5. The longitudinal slot (not shown) of the shoot extends from above coil 3 to below coil 4, and may be filled with insulating material.

Title: Transistor amplifier stage with device in its temperature compensated bias network used as preliminary amplifier
IPC: H03K12/00
Filed: 1973-09-08
Abstract: A collector-loaded grounded-emitter transistor amplifier output stage employs a temperature-compensated bias network with an auxiliary transistor having its base electrode supplied quiescent current exclusively through a resistive element connecting the base and collector electrodes. A source of input signal is coupled to the base electrode of the auxiliary transistor by capacitative means and decoupled by resistive means from the collector electrode thereof. The temperature stabilizing auxiliary transistor accordingly provides a preliminary amplification of input signals for application to the base electrode of the output stage amplifier transistor, without use of additional active devices.

The air duct means are so located relative to outlet and inlet ports of the reservoir that fluid flowing from the inlet to the outlet port will be deflected or baffled by the duct means.
Patent ES-435874-A1 (ES)
Title: Band conveyors
IPC: B65G15/54
Filed: 1975-03-21
Abstract: In a conveyor band which has load-bearing components of expandible plastics material hinged to transverse rods with two or more of the components extending end-to-end across the width of the band between each adjacent pair of rods, interengaging projections and flexible portions are provided at the adjacent ends of the components. Normally the flexible portions are unflexed and the projections space the adjacent ends of the components apart, but in the event of expansion of the plastics material, for example as a result of water absorption, which causes lateral expansion of the components, the flexible portions flex under the effect of the increased pressure exerted on them by the projections and permit the components to move closer together. Thus expansion of the components is accommodated internally of the band, leaving its width unaltered.

Title: Brake slack adjusters
IPC: F16D65/56
Filed: 1975-07-03
Abstract: An automatic slack adjuster for a vehicle brake is disposed between a piston and another component, such as a counter piston, of a hydraulic actuator. The adjuster mechanism is housed in an encapsulating container which is positively attached to the piston. A strut, on which an auxiliary mechanical actuator fitted to said other component acts, is in screw-threaded connection with a nut of the adjuster mechanism. The adjuster mechanism is of the incremental type and is adapted to turn the nut responsively to excess axial travel between the container and the strut upon hydraulic brake application, the strut being sealed to said other actuator component. Grossly excessive travel between the piston and the other actuator component beyond the maximum possible travel between the strut and the container is permitted by displacement of the strut relative to said other component.

The face of the mandrel is tapered to laterally deflect the previously bent end so that the other end may be bent without interference from a previously bent portion.
