Title: Speech synthesizing arrangement having at least two distortion circuits
Inventor: RIEMENS KAREL
IPC: G10L19/02
Filed: 1980-10-31
Granted: 1985-01-17
Abstract: Speech synthesizing arrangement for use in both voice-excited channel and formant vocoders. To derive an excitation signal from a base-band, signal distortion networks are used in these vocoders. Simple distortion networks have the drawback that the natural sound of the reproduced speech signals leaves much to be desired for. Networks which give a better guarantee for a more natural speech reproductive have the drawback that they are of a rather complicated design. According to the invention, an improved natural sound of the reproduced speech is obtained, using simple networks, by generating separate excitation signals for different frequency ranges by means of at least two separate distortion networks.

Title: Method and apparatus for assembling wood structures
Inventor: BURGER RAYMOND
IPC: B27F7/15
Filed: 1981-12-21
Granted: 1985-04-25
Abstract: Wooden structures are assembled from a plurality of wooden elements with interposed metallic connectors, by assembling the wooden elements on a work table provided with a rectangular grid. The image of the structure to be assembled, with a superposed grid corresponding to the grid on the table, is projected on the table until the respective grids register with each other. Then the wooden elements are assembled on the picture; and as the corners of the grid on the table are tapped holes, retainers can be used to hold the assembled elements in place. The table with thus-assembled wooden elements is then run through an endless belt press having superposed convergent runs, whereby the metallic connectors are sunk into the wooden elements to complete assembly of the structure, after which the completed structures are removed from the tables onto rollers with interspersed lifting arms that swing vertically about an axis parallel to the direction of movement of the tables. The arms are mounted on a carriage that moves horizontally perpendicular to the direction of movement of the tables to deliver a completed wooden structure to a stack and to return to receive the next structure.

Title: Ointment bases for dermatological and cosmetic use
Inventor: SUESS HANS R DR
IPC: A61K9/06
Filed: 1981-03-18
Granted: 1985-09-12
Abstract: Petrolatum fractions in which to a large extent no white oils are present are combined with a volatile siloxane, hexamethyldisiloxane, octamethylcyclotetrasiloxane and/or decamethylcyclopentasiloxane to provide an ointment base which enables these petrolatum fractions to be spread easily on the skin. Evaporation of the solvent leaves a vaseline film on the skin that is nonirritating and yet highly resistive to washing away. A high melting microcrystalline wax as an additive can reduce the lustre of the film. Lower alcohols can also be added to make spreading still easier.

Title: Improvements in and relating to glass fibres for optical communication
Inventor: BEALES KEITH JOHN
IPC: C03B37/025
Filed: 1981-07-16
Granted: 1989-09-28
Abstract: A glass fibre for optical communication is formed by a vapor deposition process on the inside surface of pure silica substrate tube. The substrate forms the outer cladding whilst the inner and core are formed by the deposited layers. An intermediate layer of the cladding has a refractive-index similar to pure silica but due to compensating dopants. Thus deposition and sintering temperature is reduced. The inner layer of the cladding is however undoped pure silica, thus reducing absorption losses in this important region.A step in a process for making optical fibres comprising collapsing a tubular substrate to provide a preform is carried out in a stream of pure chlorine vapour acting as a drying agent.

Title: Control valve for a high pressure hydraulic system
Inventor: BRUNNER RUDOLF
IPC: F16K11/065
Filed: 1984-03-09
Granted: 1987-01-08
Abstract: Control valve device, in particular for hydraulic systems having high flow rates, comprising a housing provided with a bore within which a piston slide means can be displaced from a neutral position with zero-pressure flow to at least one control position, and further comprising at least one pressure passage leading to and at least one discharge passage leading away from the housing bore, said pressure passage and discharge passage being adapted to be interconnected through flow conduits provided in the piston slide means. In known control valve devices of this type, the flow paths for the zero-pressure flow must be very large in the case of high flow rates; when the piston slide means carries out adjusting movements, undesirable jamming forces are caused at said piston slide means which obstruct the adjusting movements, herein avoided by providing the features that within the housing bore the discharge passage orifice is displaced relative to the pressure passage orifice in the longitudinal direction of the bore, that these orifices are diametrically opposed by recesses of the same size, which are each open towards the housing bore and which each have applied thereto the pressure existing in the opposite passage via connection passages provided within the housing or within the piston slide means, and that the piston slide means has provided therein in front of each passage orifice a longitudinally extending pocket bridging the displacement between the passage orifice and a neighboring recess.
