Abstract: ABSTRACT OF THE DISCLOSURE       The process for rendering wool sliver shrinkproof involves complete wetting of at least one laterally unguided wool sliver with a chlorinating liquor at ambient temperature wherein the liquor is applied to the sliver with a four- to sevenfold excess.          The sliver is conducted immediately thereafter through a guide slot, together with the applied excess quantity of liquid; the complete wetting of the fibers of the sliver with the chlorinating liquor is effected in this guide slot by separating the wool sliver from possible air occlusions. Subsequently thereto, the sliver is accompanied by the liquor through a small-volume guide channel, to be squeezed out following the chlorine treatment. The apparatus has a pair of squeeze rolls, the cylinders of which are arranged to be spaced apart to form a guide slot and are rotatably mounted, these squeeze rolls being associated immediately thereabove with spray means to supply the chlorinating liquor necessary for complete wetting.

Abstract: ABSTRACT     A miniature hearing aid is disclosed with input transducer (18), amplifier (19) and control elements (8, 10) as well as a current source and output transducer (20), where at least a part of the amplifier (19) is applied on mounting surfaces hinged together and lying on mounting plates (46 to 49) and the articulated connections (60 to 63) have a flexible support provided with electrically conducting tracks (50 to 52, 57).  The desideratum is, in view of the small space in miniature hearing aids, to obtain a large area for the application of the structural part or elements.  This is achieved according to the invention in that the amplifier (19) is designed as a multi-layered system which comprises at least three layers (40 to 42), of which the two outer ones (42, 43) carry the physical or structural elements (53, 54, 54.2), lie at a so-called neutral intermediate layer (40) provided with conductor paths (57), and are subdivided at several mutually opposite points into structural sections, and that the mechanical strength of the intermediate layer (40) permits deformation of the arrangement.  The invention is applicable for hearing aids to be worn in the vicinity of the ear, in particular hearing aids to be worn behind the ear.

Abstract: Abstract of the Disclosure A method and apparatus for producing a container made from a tubular blank of polyethylene terephthalate or similar material, according to which the polyethylene terephthalate blank is stretched at least approximately 3-fold to produce a preform.  In an axial section through the preform, the contour length substantially corresponds to the contour length in an axial section through the final container.  The preform is heated to a temperature above the glass transition temperature (TG) and is converted to the container in a blowmould.  In doing so, the contour length of the material is maintained through successive reduction of the axial length of the body which the preform constitutes during the conver-sion to the container.  In order to achieve this, the base portion of the blowmould is moved towards the orifice of the final container.  The container acquires a neck portion and a container body which are axially oriented, in the case of polyethylene terephthalate to an extent corresponding to an about 3-fold monoaxial stretching, whilst the container body is also trans-versely oriented, in the case of polyethylene tereph-thalate to an extent corresponding to an about 3-fold stretching as a maximum.  The wall thickness of the container is inversely proportional to the radius of the container.  The container is dimensionally very stable and has excellent strength characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE     A PLL frequency detector or comparator is provided having an up-down counter, responsive to beat signals produced by the input periodic waveforms of the VCO reference signals and the input data signals, to produce top and bottom output signals which enable multivibrators connected to each of the input signal lines to transmit overflow and underflow output pulses, whose sum is proportional to the difference in frequency of the input signals up to a predetermined maximum level, as control signals for the PLL loop filter.  The up-down counter may include three or more states with buffer states which prevent generation of overflow or underflow output signals when the PLL is within a predetermined region of phase-lock and the sign of the beat signal oscillates.  The up-down counter may also be employed simultaneously as a phase detector or comparator, wherein the top and bottom output signals are combined so as to produce control signals for the PLL loop filter when the overflow and underflow output signals are not generated.

Abstract: Abstract of the Disclosure A process for bonding a silicon die to a package.  This process comprises the following steps:  (a) providing to the back surface of the die a barrier layer which is impervious to silicon; (b) providing to the barrier layer a layer of gold; and (c) bonding the die to the package by activating a binder composition disposed at the interface of the package and the layer of gold.  The barrier layer prevents the migration of silicon to the gold layer, both at the time of application of the gold layer to the die and at the time of bonding the die to the package.  Titanium and tungsten are preferred barrier layer materials, while the preferred binder composition is a gold-tin alloy solder.  The prevention of silicon migration into the gold produces highly reliable bonds.
