Abstract: A Delta-Sigma modulator for one-bit analog to digital conversion of a signal (U(t)), such as a telephone voice channel signal to digital form is disclosed. The voice signal is sampled (1, 3, C<sub>1</sub>) at a rate high compared to the highest voice channel frequency component. Sampled instantaneous signal values are integrated (4, C<sub>3</sub>), re-sampled (10, 12, C<sub>4</sub>) and again integrated (17, C<sub>6</sub>) to reduce encoding noise. Finally, a bi-level sense identifying circuit (19) links the second integrator output to a D type flip-flop (20) providing the one-bit encoder output (b(n)).The sampling and integrator control is effected by switching in a capacitor charge shifting arrangement under clock control and feedback is applied as a capacitor switching program modification (301, 302).

Abstract: A process for manufacturing articles of filter paper in which the wet strength of the regions of weak points resulting from mechanical working is increased by the application of a wet strengthener of cross-linked cationic polyalkylenimines. For this purpose, the wet strengthener is applied only to the regions of the weak points after the filter paper has been manufactured. Seams or edge reinforcements are formed by relief printing before the application of the wet strengthener and a heat treatment takes place after application of the thermoplastic wet strengthener to cause the wet strengthener to harden. The application of the wet strengthener is effected in measured doses so that the legally prescribed maximum amounts to be added are not exceeded.

Title: Hands free telecommunications apparatus and method
Inventor: TOWNSEND BRUCE L
IPC: H04M9/08
Filed: 1989-10-24
Granted: 1994-07-12
Abstract: In a hands free communications terminal apparatus, a loudspeaker and a microphone are permitted to be simultaneously active.  A controller monitors signals in transmit and receive paths to direct operations of transversal filters to provide two echo canceler functions, one for the microphone and one for a telephone line so that most unwanted echo and feedback is removed, to prevent the howling and squealing sounds that commonly occur when the loudspeaker and the microphone are both active.  Remaining echoes are removed by voice switching of loss between transmit and receive paths, wherein the amount of loss is determined in response characteristics of the telephone line and the operating environment of the terminal apparatus.

Abstract: A pusher blade and its housing are described, in which the blade has a stiff front end for engaging slide-type test elements, and a flexible body portion and back end.  The housing forces the blade to curve through an angle, preferably about 90°C, to minimize the extension in one direction the blade would have if it were entirely rigid.          The housing can provide for separate stacks of elements in separate environments to be engaged by the blade, since sealing means are provided for preventing substantial intermixing of the environments when the blade is activated.

Title: Sonet h4 byte generator
Inventor: WILLIAMS TIMOTHY J
IPC: H04Q11/04
Filed: 1990-05-11
Granted: 1994-07-05
Abstract: An H4 byte generating algorithm is implemented by circuitry which includes counters for generating the H4 byte.  The circuit is provisioned to indicate whether it is operating in a terminal multiplexer mode or an add-drop multiplexer mode.  In the terminal multiplexer mode the counters are allowed to free run and continually produce successive H4 byte outputs.  In the add-drop multiplexer mode selected counter outputs are compared with the received H4 byte and the number of mismatches is accumulated by a mismatch counter.  When the mismatch counter reaches a predetermined number the value of the received H4 byte is loaded into the H4 byte counters and the mismatch counter is reset.  Each time a proper match between H4 counter outputs and the received H4 byte is sensed, the mismatch counter is reset to 0.  The presence of a red alarm will also result in the resetting of the mismatch counter and free running of the H4 byte counters.

Abstract: A method and apparatus for expulsion or control of humidity in a concrete and/or masonry structure wherein one or more electrodes are provided in the structure. The electrodes are made of a non-corrosive material, and connected in series or parallel with the current source. An earth electrode is provided adjacent to or on the structure. The electrode(s) represents the anode and the earth electrode represents the cathode in an electrode circuit when they are connected with the respective outputs in the current source. The anode and cathode are provided with a pulse voltage supplied by the current source. The pulse voltage is delivered sequentially as pulse sequences of a given pattern.  The anode is fed with a pulse sequence generated with a first negative pulse, followed by a neutral interval of zero voltage of a duration between 0 - 2 times the duration of the negative pulse, followed by a positive pulse, the duration of which is about 6 times the duration of the negative pulse and by simultaneously feeding the cathode with a corresponding pulse sequence, but with inverted polarity. The method includes a first phase for quick reduction of the relative humidity in the structure (typically two weeks) with a pulse sequence frequency of about 1 - 0.5 Hz followed by a second phase for maintenance of a permanently low humidity content (with a pulse sequence frequency of about 0.2 - 0.1 times the pulse sequence frequency of the first phase).

Title: Constant tension winch having an anti-theft mechanism
Inventor: STEPHENSON EVERETT H
IPC: B60P7/08
Filed: 1992-01-23
Granted: 1995-08-08
Abstract: Methods and apparatus for maintaining a restraining means placed over a load in constant tension as the load shifts during transit are disclosed.  The present invention provides a winch having two ratchets,  the first of which provides the initial tension in the restraining means.  The second ratchet is connected to a spring, which is connected to the shaft upon which the restraining means is wound.  By operating the second ratchet, the spring is displaced and an urging force is created.   Upon a reduction of the initial tension in the restraining means, the urging force acts upon the shaft, advancing the shaft and the first ratchet, thereby maintaining the tension in the restraining means. Since the first ratchet is advanced, any slack in the restraining means is  accumulated and the  strap  is  locked  into  a  tighter position.  Methods and apparatus providing a locking bar to prevent unauthorized use of the winch and theft of the restraining means are also disclosed.
