Title: Hand scoop with one elastic arm - squeezing of the two arms together moves a stripper
Inventor: COOPER WILLIAM TREVOR
IPC: A47J43/28
Filed: 1973-12-28
Abstract: A hand scoop for ladling out food stuffs has a second arm made of a springy, elastically yielding material which acts together with the first arm in such a way, that it can be moved against it by force of hand to cause a stripper to move. The stripper returns to its original position by itself due to the inherent elasticity of the material when the force of hand is removed. The cup pref. goes over into the first arm by way of a short shaft which forms a single unit with the cup. The first and second arms are pref. made of plastic. The scoop is of simple construction and does not have to be stripped for cleaning.

Title: Tariff adjustment device - has generator delivering pulses to indicate consumption of certain quantity
Inventor: VRIES JACOB DE
IPC: G01R21/133
Filed: 1974-01-15
Abstract: The generator delivers pulses signalling the consumption of a certain fixed quantity to a counter connected to it via a gate. The gate is a digital pulse frequency separator with several outputs, each connected to a summating counter. The pulse frequency separator directs a fixed quantity signalling pulse to one of the counters, depending on its distance from the preceding fixed quantity pulse.

IPC: C25D7/06
Filed: 1974-06-12
Abstract: A device for making a wire from scrap metal and waste metal electrolytically comprises a ceramic tank contg. a copper sulphate soln., through which a core wire is conducted intermittently; the wire is advanced by means of a gripping block propelled by a threaded spindle, driven by a gear train from a motor; during electrolysis, while the current is switched on, the block is outside the bath, so that it does not become coated; afte a given length of wire has been deposited on the core wire, the current is switched off, the drive is reversed to bring the block back to the bottom end, and the drive is then advanced to pull out the finished length of wire; the drive is then stopped and the current switched on again. The bath may contain a conducting contact tank in which copper or other waste is placed. The block may have an insulating elastic sleeve adjacent to it, which is pushed back by the block so that a uniform cross-section of the total length of wire is always obtd. The pulling device is pref. tensioned to keep the core wire taught but not to stretch the fully coated wire. A slip clutch may be provided for this purpose.

Abstract: 1479005 Electronic musical instruments; teaching devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 24 June 1974 [23 June 1973] 28001/74 Headings G5J and G5X A musical signal system comprises a tone generator 26 actuated by a signal Sm from a memory device 24 such that any electrical audio frequency input signal S100 sensed by a sensor 22 as falling within predetermined frequency bands, each containing a note of a musical scale, is output as a more accurate representation of that note. The signal S100 may be derived from a human voice or musical instrument. The input bands may be abutting, separated or overlapping (e.g. Figs. 2, 12 and 13, respectively, not shown) and the outputs may be scale notes in the same input frequency bands or shifted therefrom by a predetermined multiple (Figs. 2 and 14 respectively, not shown) or may be a frequency lying in an output band which is narrower than the input band (Figs. 17, 19, not shown). When the input frequency bands overlap, two output frequencies may result and when the input bands are separated by a gap, no tone may be output if an input frequency is in the gap. The output may be controlled to provide vibrato or portamento as sensed at the input (Figs. 21, 22 respectively, not shown) or may be changed from one musical scale to another based on a different standard concept pitch (Fig. 20, not shown). The tone generator 26 may be suitably controlled separate oscillators (e.g. Figs. 3 and 5, not shown) or may be a controlled frequency divider coupled to a single oscillator (Figs. 9 and 10, not shown). The system may be used for teaching pitch accuracy.

Title: Moving bed ion exchange plant - in which resin is moved to another position on exhaustion for regeneration
Inventor: ARION NICOLAE MIHAIL DIPL ING
IPC: B01J47/10
Filed: 1974-07-29
Abstract: Plant is intended for softening and demineralising strongly saline water, in the concn. of dil. solns. of certain precious salts, in the purificn. of (in)org. solns., in the treatment of waste water and in other techniques using the ion exchange principle. The appts. consists of two vertical cylindrical columns connected at the base by a 180 degrees elbow. The effluent enters at the bottom of the fixation section and leaves at the top. When a continuous analyser shows that the resin is exhausted, it is replaced by regenerated resin, stored in a conditioning section, by means of a piston effect produced by hydraulic impulses. The exhausted resin is transferred by similar means to a regenerating section and then to a rinsing section and finally to the conditioning section where it is stored until required. Effluents can be treated at different flow rates and high concns. of regenerating agents can be employed, such as 45-60% HNO3 or 30-50% H2SO4.

Abstract: Stable water-in-oil type emulsions, are made by: dissolving or dispersing an acid or neutral eye in water contg. (A) a surfactant mixt. of 0.5-3 vol.% coconut fatty acid/diethanolamine condensate, 1-10 vol.% ethoxylated nonyl phenol, and 87-98.5 vol.% phosphate mono-and di-esters of nonyl phenol condensed with 4-9 mols ethylene oxide, and (B) a solvent e.g. perchlorethylene and /or trichlorethylene, in amount of 0.8-1.2 vols. per part of (A). The soln. is further diluted with solvent to give 0.1-6 wt.% dye and at least 0.5 wt.% (A) based on wt. of fabric being dyed. The emulsions are used for immersion dyeing of wool, cellulose and/or polyamide fabrics or yarns. Stable emulsions are obtained by simple stirring which do not require constant circulation and milling during dyeing. This is carried out at lower temps. than usual causing less shrinkage of the fibres, less corrosion and erosion of the equipment and reduced pollution.

Title: Prewelding surface treatment of metals - by directing powder or gas jets against surface
IPC: B23K9/23
Filed: 1974-10-01
Abstract: The surfaces of parts are treated prior to a welding or other joining operation by directing a jet of gas mixed with particles (powder) against them. The jet emerges centrally from an electrode or from several electrodes and can be deflected by a pure gas stream. This combines a simple, fast and thorough cleaning of the surface with the prodn. of a desired surface structure. The result is a satisfactory and reproducible high-quality joint. This method can be applied prior to arc welding, ultrasonic welding, soldering or cold pressing.
