Abstract: A filter element made of non-woven fabric formed as a folded package is self-supporting and is composed of thermally sealable non-woven fabric (1). Each of the two outer edges (3) of the folded package (2) is lined by the non-woven fabric material (1) forming the folds (4), which material, at each folded edge (3), is folded over in the same direction and is fixed to the corresponding bent edge of the adjacent end of fold in a tight fitting manner. The non-woven fabric material overlaps each bent edge of the adjacent end of fold by 1.5 to 2.5 times the fold separation. 
<??>To produce the filter element, the flat filter medium (1) is first folded and then a defined fold separation (7) is produced by a limited stretching perpendicular to the folding. The two outer edges (8) of the folded package are then positively clamped into comb-like sections (9) corresponding to the geometry and dimensions of the folds, and penetrating pincer-like into the folds on the upper and lower sides, the filter material projecting over the shaped sections (9) on each side by 1.5 to 2.5 times the fold separation (7). The overlapping material (10) is folded down on both sides in each case by means of a first pressing element (11) having a sideways action thereon, until the overlapping material (10) fits on the adjacent end of fold, so that the edges overlap. Energy allowing thermal sealing is supplied via these pressing elements (11). Further subsequent pressing elements (12) fix the sealed sites during cooling. The comb-like sections (9) are then removed and the folded package is contracted.

Abstract: A fabric intended to serve as an insert in working trousers or trouser legs for power-saw operators. The fabric consists of two layers, viz. a carrier layer or passive layer, wherein the threads interconnect the threads of the active layer, i.e. the layer wherein on account of the contraction of the passive layer threads caused by suitable treatment of them, the threads of the active layer are forced to take on a sinuous configuration whereby at their contact with the saw chain the sinuous sections will be caught by the chain, and the threads of the active layer by pulled out and thus so heavily oppose the movement of the saw chain that the latter is immobilized.

Date Feb. 20, 1997Amplitude and phase errors between branches I and Q of a transceiver utilizing phase quadrature modulation are corrected by preventing propagation of a nominal-frequency signal from a digital part through a loop part and a reception branch to an RSSI indicator by changing the frequency response of a component on the path of the signal. The same indicator that normally measures the payload signal, here measures only undesired signal components. After this, such amplitude and/or phase correction signals are determined with which the measuring result obtained from the indicator reaches the minimum. The resultant correction signals are stored in the memory, and the frequency response of the system is then restored to normal.

Date Apr. 6, 1989.In a process for transfer pattern printing of a moist textile web consisting wholly or predominantly of natural fibers, in particular cotton, and/or artificial fibers on the basis of cellulose, the pattern carrier web is a web of paper or a paper-like material which carries a pre-printed pattern of a water soluble or dispersable dye. After wetting of the textile web to a carefully controlled moisture, the textile web is joined with the pattern carrier web and the joined webs are compressed at a suitable pressure so that the pattern can be transferred without using heat. The advantage is that it will be possible to avoid both heating and use of organic solvents. It is also possible to transfer a pattern to a colored textile web since the textile web may be wetted before hand with an aqueous dye solution or dispersion instead of undyed liquid.

Abstract: A process for controlling the brightness (dimming) of a gas-discharge lamp (GE) which is located in a series resonant circuit (L1, C1) connected to a rectifier-inverter combination (10, 20), by varying the frequency (f) and the duty ratio (D, d) of the output alternating variable (uw) generated by the inverter and supplied to the gas-discharge lamp and to the series-resonant circuit (X; L1, C1, GE). The lamp (GE) is operated in a frequency range in which the dependency of the lamp power (Pab) on the frequency (f) of the output alternating variable (uw) can be represented by the duty ratio (D, d) as a parameter as a family of characteristic curves (K1, K2, K3, ...), each of which runs in the manner of a bell-shaped curve starting from a maximum value and reducing to form a point of inversion. The maximum value of the individual characteristic curves (K1, K2, K3, ...) of the family becomes smaller as the duty ratio (d1, d2, d3, ...) associated with these characteristic curves (K1, K2, K3, ...) as a parameter becomes smaller. The process is intended to be designed such that the brightness of a gas-discharge lamp can be varied in a stable manner without flicker. This is achieved in that the frequency (f) and the duty ratio (D, d) are in each case selected such that the operating point (B1, B2, B3, ...), with at least two characteristic curves selected or available for a specific lamp power (Pab), in each case coming to rest on that characteristic curve which has the lower gradient at this lamp power (brightness). <IMAGE>

Inventor: LAGONI WILLIAM ADAMSON
IPC: H04N5/20
Filed: 1990-08-23
Granted: 1996-01-30
Abstract: The present invention concerns a non-linear transfer function generator, e.g., for implementating "white stretch" of a luminance signal. Specifically, first and second emitter-follower amplifiers have their inputs coupled in parallel and their outputs coupled in series via first resistor of a voltage divider. A second resistor of the voltage divider is coupled to a point of reference potential. A bias source is coupled to the second amplifier, e.g., via the second resistor of the voltage divider, so that the dynamic response of the second amplifier to an input signal is limited with respect to the first amplifier. The output signal of the first amplifier is linear and an output signal developed at the output of the first amplifier is non-linear. The linear and non-linear output signals are combined by a current steering network in response to a control signal representative of a characteristic of a processed version of the luminance signal.
