Patent CH-680868-A5 (CH)
Inventor: HERWEGH NORBERT
IPC: E06B3/62
Filed: 1990-08-13
Abstract: The profiled sealing strip is formed essentially of a sealing lip (4), a root region (9) and a foot (10) and has two limbs (13, 14). These limbs are at right angles to one another and are connected to the sealing lip (4) and a foot (10) via constrictions (15, 17), so that they can be twisted when subjected to force. Their common joint forms a sealing point (22) which is situated at the same level as a sealing point (12c) which is formed by a rib (12) disposed in the root region (9). The sides (20, 21) of the two limbs (13, 14) together with the root region (9) bound a hollow space (18). The side (19) formed by the root region (9) is shaped in such a way that when a force acts on the sealing point (22) of the two limbs, said side is displaced approximately horizontally towards the root region (9). It therefore remains within a narrow region (23) containing the two sealing points (12c, 22). By making cuts above and below this region, the profiled sealing strip can thus bend through 90 DEG  at the corners of the window, there nevertheless being no interruption in the two sealing points (12c, 22) so that they ensure continuous sealing even around such a bending. <IMAGE>

Inventor: ACKERMANN HORST WILHELM
IPC: B65D77/06
Filed: 1984-07-05
Abstract: The invention relates to a resealable pack consisting of an outer, relatively rigid envelope and a flexible, gusseted inner bag attached to the envelope, in which the outer envelope comprises at least one flap which, when turned down to seal the pack, folds and squeezes the two faces of the open end of the bag. The two lateral walls of the outer envelope have no moveable parts.

Title: Arrangement for balancing the different attenuation characteristics of telecommunications lines
Inventor: BRUECKNER EGON
IPC: H04M7/04
Filed: 1982-06-01
Abstract: In a telecommunications line, in particular a two-wire trunk line, a compressor-amplifier (KVI, KVII) in each case containing non-linear components is provided for both traffic directions. Both compressor-amplifiers (KVI, KVII) are disposed in a hybrid amplifier circuit (G) and are controlled by a control device (ST) in such a way that the log of the sum of the two amplifications does not exceed double the minimum value of the transhybrid loss (aü). A speech recognition circuit (SPI, SPII) which is connected to the control device (ST) is disposed upstream of each amplifier input in order to adapt the transmission characteristics of the amplifier (e.g. KVI) of the respective active direction to its input level and to set the level of the other amplifier (KVII) according to the aforementioned relationship. Two-way traffic is thus enabled without the risk of self-excited oscillations. <IMAGE>

Patent CH-684574-A5 (CH)
Title: Device for the evaporation of a liquid agent to influence the ambient air
Inventor: WEICK HEINZ HERMANN
IPC: A61L9/12
Filed: 1992-12-16
Abstract: The device is intended for the evaporation of an agent to influence the ambient air. Essentially it comprises a base plate (1), two enveloping bodies (3, 4) and the agent reservoir (5) which is designed as a small bottle and contains the vaporisation rod (6). By their ends (3a, 4a) the enveloping bodies (3, 4) are mounted concentrically and so as to be rotatable relative to one another on the base plate (1). At the top, the enveloping bodies (3, 4) are tapered like leaf-shaped lamellae (3a, 4a). The small bottle (5) with the agent (11) together with the vaporisation rod (6) forms an exchangeable unit. The vaporisation region (6a) of the vaporisation rod (6) that projects beyond the neck (5b) of the small bottle is fabricated so that it is surrounded by a screwed-on sleeve (9) to be removed by the user. The enveloping bodies (3, 4) can be adjusted through a vaporisation angle of 180 DEG  relative to one another. Thus, the selectable vaporisation spectrum is much larger than that of conventional, cylindrical enveloping bodies provided with vaporisation slots. Moreover, the particular vaporisation position adjusted can be recognised from a distance because the spatial shape changes from setting to setting. The design is compact, and the cuff (12) which is inverted over the neck (5b) of the small bottle and is designed as a leaf rim forms an attractive transition between the small bottle (5) and the vaporisation rod (6). <IMAGE>

Patent CH-613809-A5 (CH)
Title: Current limiter/circuit breaker
Inventor: KHALID JOSEPH MOHAMED
IPC: H01H71/43
Filed: 1975-04-29
Abstract: The current limiter/circuit breaker is provided with means for cutting the current in the event of a surge. In addition to a first pair of contacts (53, 70) actuated thermally or magnetically, a second pair of contacts (153, 155) is provided on current-conducting blades (152, 154). Electromagnetic means of actuation (148a, 156, 182) with movable armature, bring about separation of the contacts of this second pair in response to a current surge in the said blades (152, 154) which exceeds the value of the surges required to actuate the contacts of the first pair. To provide for this performance, an auxiliary electromagnetic arc-diversion arrangement (188d, 181) is provided in order, at the requisite moment, to supply a magnetic field directed perpendicularly to the electric arc forming during separation of the contacts of the second pair. <IMAGE>

Title: Wall element prefabrication palette formwork - has various side form finishes fitted between head and base forms
IPC: B28B7/00
Filed: 1975-06-12
Abstract: The paletted formwork is for industrialised production of concrete wall elements on a grid system, permitting varying formats with differently arranged openings and corner and edge configurations, and applicable to both negative and positive prefabrication processes. The base form finish (2) is attached to a bench panel (11) of the palette (2), so that it can be swivelled and firmly clamped. There is a head form finish (3), parallel to the base, which can be displaced and fixed on the bench panel. Demountable side form finishes (5, 18) are fixed at right angles to these, between them or on them, with auxiliary profile units (6, 7, 8). The whole is assembled so that in one arrangement the formwork can be used for positive fabrication and in another for negative fabrication.

Title: Reading machine for blind persons - converts signals denoting alpha-numeric characters into audio signals
IPC: G09B21/00
Filed: 1973-03-05
Granted: 1974-10-04
Abstract: The machine detects each character of a written text using photo-electric cells, and the signals obtained are used to control a recording disc carrying parallel tracks each representing one letter of the alphabet. The characters are enlarged before detection. This is performed by focussing them onto a grid defined by the cells. Each cell produces a note of a characteristic pitch when it falls on part of a letter, so that each letter or normal typescript produces a characteristic chord. The text is recorded using the reading head and the record may be played back when required.

Patent DD-157795-A5 (DD)
Inventor: ROMANO UGO
IPC: C07C68/06
Filed: 1981-03-04
Abstract: The application relates to a process for synthesising carbonic allyl esters from polyhydric alcohols, which are reacted with diallyl carbonate in the presence of a basic catalyst, which can be chosen from sodium hydroxide, sodium carbonate, sodium alcoholate, organic bases or basic ion exchange resins.The final products obtained differ according to the ratio of the components of the starting mixture. Thus, in the case of diols with a diallyl carbonate/diol ratio greater than or equal to 10, the resultant product is constituted by the bis allyl carbonate of the diol together with a quantity of less than or equal to 10% of oligomers represented mainly by dimers. If the ratio is less than 10, the percentage of oligomers rises until, in the case of an approximately stoichiometric ratro, it reaches a value close to 70% of the reaction product.
