Abstract: IMPROVED APPARATUS FOR AUTOMATICALLY FORMING  HYPHENATED WORDS          ABSTRACT:    Improved hyphenation apparatus is combined with word verification apparatus to automatically provide hyphenation points for input words from a keyboard or other input de-vice.  The spelling of each word input to the system is verified by the digital reference matrix section of the apparatus by calculating a vector magnitude and angle for the word which is compared to the contents of a storage dictionary of words.  Each cell of storage in the storage dictionary, in addition to containing a unique angle repre-sentation of the input word, contains a byte of data re-presenting the valid hyphenation points for the input word.          When an input word is verified to be correctly spelled, the hyphenation byte is read out of dictionary and used by the hyphenation section to reassemble the word in hyphenated form.  The hyphenated word is then displayed to the operator for appropriate action.

Abstract: Abstract of the Disclosure It is known to provide a valve assembly in which a resilient housing has a passageway therethrough which is normally blocked by a plug located in the passageway.    This form of valve assembly can be opened by inserting a rod or tube within the passageway to engage projections formed on the inside of the housing and thereby distort the housing away from the plug to form a fluid passageway between the plug and housing.    In the present invention a valve assembly has a unitary plastics body located within a resilient housing of plastics material. The body is closed at one end by a dish-shape portion having a circumferential lip which forms a seal with the housing.    The body has a tongue formed in its wall, one end of the tongue being provided with an inwardly directed tooth.    By inserting a tube or rod within the valve element to engage the tooth, the tongue can be displaced outwardly and the overlying part of the housing can thereby be distorted away from the lip to permit fluid flow through the housing.    The valve assembly may be used to seal one end of the inflation line of a cuffed medico-surgical tube.

Abstract: ABSTRACT      Problems arise when erecting a sheet pile on rock substratum and subsequently anchoring the piles. If a channel is blasted, this has the draw-back that the over burden has to be initially cleared prior to blasting and then replaced subsequently. In addition, the piles when secured in the blasted channel when refilled with concrete and the anchors in the rock substratum are not as securely supported as piles driven into normal substratum.  A method of erecting sheet pile and a method of anchoring the sheet pile is disclosed where the substratum is shattered by blasting sufficiently to allow the piles and the anchors, which are also piles, to be driven into the rock substratum. Each method involves drilling bore holes and inserting a water tight charged container into these and determining the volume of charge relative to container volume such that the rock substratum surrounding a bore hole after detonation is not significantly damaged in its external form but has a shattered internal structure allowing pile driving.

Abstract: EXPANSION AND COMPRESSION OF TELEVISION             SIGNALS BY USE OF DIFFERENTIAL CODING     Abstract of Disclosure The encoding of television signals, to be either processed or transmitted in numerical form, uses a modulation of differential code impulses (PDCM).  There is a quantizing characteristic which makes it possible to reduce the numerical flow of signals to be either processed or transmitted.  At least partially, the quantizing characteristic is non-symmetrical relative to zero, as far as the number and the values of the thresholds and of the reconstruction difference levels are concerned.  Numerical examples are given  in the specification.  According to a variation of the invention, the quantizing characteristic varies as a function of a prediction value Pn.  The prediction zones are not symmetrical relative to the half-dynamic of the prediction Pn.  The quantizing characteristics are segments of a wide characteristic which preferably is non-symmetrical.

Abstract: ABSTRACT: "Shaving apparatus".     The invention relates to a shaving apparatus having a cutting unit with at least one cutter which is equipped with a lead cutter which is movable relative to the cutter.   The lead cutter pulls at a hair, so that the cutter cuts the hair when it is slightly pulled out of the skin.            The lead cutter should be positioned accurately relative to the cutter. The lead cutter should be movable relative to the cutter under the influence of the forces exerted on it by a hair, but when these forces cease the lead cutter should return to the initial position. This is achieved by means of a very simple construction, the lead cutter being connected to the cutter by means of a connecting element of a material with rubber-elastic properties.
