Granted: 1997-10-14
Abstract: A specially constructed block for use in forming a mortarless retaining wall is disclosed, as is a retaining wall constructed therefrom and a method of constructing a retaining wall.  Each block has a front face of a predetermined width and a rear wall having a substantially equal width.  The block side walls provide a maximum block width at the front face and a minimum block width adjacent the rear wall.  When such blocks are placed in a side-by-side relationship, a substantially closed cavity is formed between the blocks for receiving backfill material and thereby reinforcing the wall.  A wall constructed from a plurality of such blocks utilizes an engagement clip disposed between blocks in upper and lower courses for preventing relative forward movement between the blocks.  The clip is engageable with the upper surface of the rear web of the block for easy installation after the block is laid in a course.  The clip engages the inner surface of the rear web of a block in an upper course, and is preferably disposed within the core of the upper block.  Each block is provided with outwardly projecting ears which can be knocked off to form a wall having a radius of outside curvature, and the ears and clips cooperate to allow construction of a wall of inside curvature.

Title: Method of controlling the frequency of a coherent radio receiver and apparatus for carrying out the method
Inventor: RAITH ALEX KRISTER
IPC: H04L27/14
Filed: 1990-01-17
Granted: 1996-11-05
Abstract: A method and an arrangement are described for controlling the frequency of a radio receiver which receives signal sequences subject to interference and which include a synchronizing sequence and a data sequence.  A signal sequence is A/D converted to signal points (I,Q) intended for analysis, and a Viterbi algorithm is adapted to the prevailing interference with the aid of the synchronizing sequence.  The data sequence is Viterbi analyzed through a large number of calculating stages, for the purpose of determining the bit sequence of the data sequence.  According to the invention, a bit sequence is extracted during the Viterbi analysis, with a time delay (TE), subsequent to effecting a few calculating stages, and a corresponding extracted signal point is calculated.  The analysis intended signal point corresponding to the extracted signal point is divided and time delayed, and phase compared  with the extracted signal point. Corresponding phase comparisons are made with respect to consecutive signal points in the data sequence and the angular magnitudes obtained in the phase comparison are low-pass filtered and integrated to form an angle shift signal. The analysis intended signal points are displaced angularly by the angle shift signal prior to the Viterbi analysis.

Granted: 1997-01-28
Abstract: A process for producing binder-containing fibrous mats from lignocellulose fibres or the like is described, in which the fibres are processed by hot pressing to shaped or moulded articles, such as for the internal lining of the passenger compartments of motor vehicles together with stabilizing additives.  The dry fibrous material thoroughly mixed with the binder is applied to a conveyor in such a way that there is an alternate application of several wood fibre layers and synthetic fibre layers.  The heap densities of the synthetic fibres and the wood fibres, considered over the mat cross-section, are in accordance with a statistical distribution, which roughly corresponds to an edge-blurred, periodic comb profile.  The base width for the synthetic fibres is much smaller than that for the wood fibres.  The individual fibre heaps are interconnected by means of suitable adhesives.

Title: Method and apparatus for sterilizing a medical unit
Inventor: HEILMANN KLAUS
IPC: A61L2/18
Filed: 1990-11-02
Granted: 1997-06-17
Abstract: This invention relates to a method for sterilizing a medical unit comprising at least two connections for insertion into a fluid flow of a medical unit where a sterilizing medium flows through the unit.            Medical units of this type are e.g. medical filters, in particular dialyzers. A high degree of sterility is here required. This is accomplished through the following steps:   a.   inserting the unit into a system under pressure-tight coupling of the two connections to a feed conduit and discharge conduit of the system under atmospheric conditions;   b.   passing the sterilizing medium from the system through the unit for a given period;   c.   germproof closing of the two connections in the coupled state, without the same being opened, on completion of the sterilization operation.   d.   removing said unit from said system as a sterile unit with closed connections.            All steps, including the removal of the unit, are therefore carried out in a system where the sterility obtained is constantly maintained. This "inline sterilization" guarantees a high degree of sterility of the medical units treated. This invention also relates to a technical apparatus for carrying out the method (FIG.1).

Inventor: BERGMAN NORMAN J
IPC: B43M5/04
Filed: 1991-02-11
Granted: 1995-12-12
Abstract: The invention disclosed herein provides for automatically controlling positioning of a moistening nozzle relative to an en-velope flap being moved therepast at high speed.  The invention has particular application as an envelope flap moistener in a high speed mailing machine.  Envelopes are moved to and past the nozzle at a speed of at least about 65 inches per second along a given path with the flap extending from the envelope in an opened configuration thereof.  A sensor attached to the nozzle senses the location of the edge of the flap within about 0.2 inch of the nozzle upstream thereof a plurality times as the flap moves to and past the nozzle.  The nozzle is then positioned to track the flap edge in accordance with sensing of the envelope flap.  The nozzle may be pre-positioned by a lower bandwidth servo system having an envelope sensor located further upstream of the track-ing sensor.  A higher bandwidth servo loop controls tracking of the nozzle in response to the tracking sensor.  It is not neces-sary to use stored or computed envelope flap profiles, envelope speed, etc., for the nozzle to track the envelope flap.

Title: Selecting the most suitable receiver antenna from two or more receiver antennas
Inventor: EKELUND BJOERN OLOF PETER
IPC: H04L1/06
Filed: 1991-04-09
Granted: 1999-09-21
Abstract: The invention relates to the selection of an antenna in a receiver of a mobile radio station which forms part of a time-multiplexed radio communication system. The signal strength of each antenna is measured in each time slot which immediately precedes the time slot intended for the station concerned, and the antenna selection is effected in dependence on the measured signal strengths. In order to eliminate the risk of unsuitable antenna selection as a result of momentary falls in signal strength, the signal strength for each antenna is measured on several occasions during the time slot in which the measurements take place. The signal-strength values for each antenna are thereafter combined linearly, so as to form a suitability measurement. The antenna having the highest suitability measurement is selected for the next arriving time slot.
