Title: Coin blanks inspection system - uses glass fibre optic to transmit light signal from blank surface
Inventor: MORASCHETTI FERDINANDO
IPC: G01N21/88
Filed: 1976-05-10
Abstract: The automatic system for checking the blanks used to make coins utilises glass fibre optics to check the blank for any surface defects. The glass fibres are assembled in two bundles (3) and (4) and bound side by side to form a common head (5). The blank to be inspected is placed under the head (5). A beam of light is directed onto the end of the fibres (3) and is reflected along the fibres (4) on to an electronic device. The electronic device compares the intensity of the reflected light with that from a perfect blank and emits an appropriate signal to accept or reject the blank.

Title: Overload protection tube for telephone equipment - has automatically closing discharge gap when inside temp. exceeds threshold
Inventor: LE CAIN YVES DOMINIQUE
IPC: H01T1/14
Filed: 1976-05-12
Abstract: An overload protection tube for use in telephone equipment is to protect the circuits from damage or breakdwon. The tube is made with a discharge tap between two discharge electrodes encased in a sealed housing. The discharge gap (11-12) can be automatically closed to produce a short-circuit when the temp. inside the tube exceeds a particular threshold value. One of the electrodes (1) is fed through an entry (7) in the casing. The fusing temp. of the entry gland material is close to the threshold. This means that the physical condition of the material will change rendering it incapable of supporting the electrode. The suction effect will cause a short circuit between the two electrode surfaces.

Title: Hop extract contg. little or no water - and consisting of resins, oils, waxes and opt. tannins
IPC: C12C3/08
Filed: 1976-06-19
Abstract: Hop extract, consisting of hop resins, -oils and -waxes and opt. tanning principleS, contains 0-10 (0-6) Prod. has improved storage-stability, is measured out more easily, can be used up better and has appearance of natural prod. Increased surface allows better determination of properties, e.g., aroma and colour. Prod. dissolves within a few mins., without leaving a residue, resists chemical changes and retains aroma components. Increased solubility leads to increased isomerisation of contents, esp. of alpha-acids to iso-alpha-acids, e.g., by 11%. Extract having a lower range water content is present as a porous cake or as a pelletisable coarse- or fine-grained or even powdery prod. High range water-contg. extract can be a kneadable material.

Title: Press moulding of thermoplastic solids, esp. coal - with peripheral heating during moulding
Inventor: KAIMANN WALTER DR ING
IPC: C10J3/30
Filed: 1977-04-01
Abstract: Prodn. of formed products from at least partially granular or powdered feed material contg. a component with temp.-dependent softening behavior is carried out by press moulding the feed material to produce a continuous strand of formed product, which is then subdivided. The improvement lies in the fact that the whole circumference of the material is heated along at least part of its path of travel during press moulding. The feed material pref. comprises a mixt. of coal and lignite contg. a minor amt. (esp. 15-25%) of lignite. If the feed material does not have the required softening properties, a thermoplastic material can be added. The process is esp. useful for producing coal briquettes contg. lignite as binder. Heating increases the surface strength and impermeability of the briquettes.
