Granted: 1989-08-17
Abstract: The present invention relates to a process for the preparation of alkoxylation products of organic carboxylic acids containing alcoholic hydroxyl groups by the reaction of any organic compounds containing at least one carboxyl group with alkylene oxides in an alkoxylation reaction in the presence of catalysts, characterized in that the catalysts used are phase transfer catalysts selected from the group consisting of (a) tetraalkylammonium or tetraalkylphosphonium halides in which the sum of carbon atoms of the alkyl groups is at least 8, (b) basic alkali metal compounds converted into complexes with crown ethers and (c) complexes of (i) basic alkali metal compounds and (ii) acyclic organic compounds containing at least 5 alkylene oxide units of the formula -R-O- (R=C1-C4-alkylene) in the form of one or more polyether chains having at least 3 alkylene oxide units, said compounds having a molecular weight of at least 238 and containing a total of at least 40% by weight of alkylene oxide units of the type indicated in polyether chains having at least 3 alkylene oxide units. The present invention also relates to the use of these alkoxylation products for the production of polyurethanes by reaction with organic polyisocyanates.

Granted: 1989-09-28
Abstract: A first plastic strip (21) has longitudinally spaced studs (22) each of which can be bent over at a 90° angle. A second strip (26) has holes (27) through which the studs fit and grooves (29) which receive and secure the bent over studs. Several stud shpes and bent stud retaining grooves are described. Paper (33) punched to receive the studs is clamped between the two strips. The studs are then bent over into grooves in the second stnps and held in bent position. The paper is thus securely bound. A channel (42) may be slipped over the outside of the second strip to conceal the bent studs and further secure them in place.

Abstract: The apparatus ensures that locking-in to the track (25) of a record carrier (1), for example a compact disc, is effected at the most eccentric point (28) of a circle (27) described by the light spot P, which is projected on the record carrier by a light beam via an objective system (8), when the record carrier rotates and the objective system is stationary. In this point the relative radial speed of the light spot P with respect to the track is minimal, so that locking-in can be effected in the simplest way at this instant. 
<??>The radial positioning means (77) are switched on at this instant under the influence of a first control signal (S1), which is applied to a lock-in system (78). 
<??>Moreover, locking-in to the track at this most eccentric point (28) has the advantage that even if the objective system is in its initial position, which means substantially against the stop it remains possible to follow the track even atter the first complete revolution of the record carrier after locking-in so that no loss of track occurs. This would be possible in the case of locking-in to the track of an eccentric record carrier at a point other than the above-mentioned point.

Abstract: A cotyloidal component for a non-cemented hip prosthesis comprises a hemispherical titanium dome member and a cup of polymer material which is engaged therein to form a friction lining and to receive the spherical head of a femoral component. The titanium dome member comprises a first zone in the form of a portion of a sphere which is angularly displaced with respect to the dome member to be tangential to the equatorial edge and to bear against the roof part of the acetabulum. Disposed in projecting relationship in the zone are two stud portions for the passage therethrough of screws provided to engage into the roof part of the acetabulum and form a primary anchoring means. The zone is covered with a covering of porous titanium capable of being invaded by growing spongy bone to form a secondary anchoring. The second zone is smooth and comprises slots along meridians of the dome member to afford a capacity for elastic deformation comparable to that of the acetabulum in the region of the horns thereof.

Abstract: There is disclosed a tachycardia control pacer in which there is generated a sequence of pacing pulses at intervals which are a function of the effective refractory period intrinsically associated with the rate of the patient heartbeats. If the tachycardia episode is nottherminated, another sequence of pulses is generated; however, the rate of the new sequence is decreased if at least one unevoked heartbeat was sensed during the preceding pacing pulse sequence and the rate is increased in the absence of any unevoked heartbeat having been sensed during the preceding pacing pulses sequence. Also, in order to smooth the transition between the fast pulses used to terminate the tachycardia episode and subsequent beating in sinus rhythm, pacing pulses continue to be generated at increasing pacing intervals until they merge into standby pacing.

Abstract: A phase regulating circuit which converts a slot clock signal at an input into a slot-free clock signal with a low jitter at an output, comprises a phase discriminator, two identical frequency dividers and a regulating and oscillator circuit. The regulating and oscillator circuit comprises a quartz crystal oscillator which supplies an auxiliary frequency, and an adding counter which generates a further signal with a further frequency. One control input of the adding counter is connected for this purpose to the output of the phase discriminator, while a second input of the adding counter is connected to the output of the quartz crystal oscillator. The auxiliary frequency and the further frequency are each connected to an input of an EXCLUSIVE OR gate by which they are added by regular polarity reversal. From this added frequency, a frequency divider obtains the frequency of the clock signal. A plurality of phase regulating circuits can operate using a common quartz crystal oscillator which is of particular interest for digital signal multiplex devices.

Abstract: A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.

Abstract: A method of producing a thixotropic material is provided which consists of deforming a fully solidified metal or metal alloy below its temperature of recrystallization by cold or warm working such as extrusion or rolling. The deformed material is then caused to recrystallize by heating and the temperature is either further raised or subsequently raised above the solidus of the material so that the recrystallized structure partially melts to provide discrete particles which spheroidize in the liquid matrix to provide a material which behaves thixotropically. The flow characteristics of the material are such that lower forming loads are required and weaker non-metallic die materials may be used.
