Patent EP-0325734-B1 (EP)
IPC: A61C13/225
Filed: 1988-11-30
Granted: 1992-12-30
Abstract: Metallic precision attachments/telescopic crowns are usually used as a releasable connection for a combined fixed/removable denture. Metal-based precision attachments must generally be soldered, welded or cast on. The incorporation of the precision attachments necessitates a considerable expenditure in terms of material and time. In the case of a loss of friction, metallic precision attachments/telescopic crowns can only be repaired (if at all) at considerable financial expense. 
<??>In order to provide a denture attachment which is cost-effective and can be used in many ways, spark erosion is used to introduce a groove profile between the telescopic crown and the attached crown of the denture part, into which groove a profile rod made of polyamide is inserted as an elastic friction element. The friction element thus formes a frictionally engaged attachment between the telescopic crown and the crown arranged on this.

Abstract: The invention relates to a method of controlling the dwell pressure of an injection moulding machine. A process computer controlling a hydraulic pressure drive of the injection moulding machine stores a predetermined reference dwell pressure time characteristic. If there is a change in the moulding material temperature Tm and/or the mould temperature Tf, a new dwell pressure time characteristic is calculated. To do so, time check points, corresponding to the reference temperature values and reference dwell pressure values, are determined.

Abstract: An out-of-balance control for a laundry machine in which the input to the control is a current signal which is proportionate to the current drawn by a motor (18) which rotates a perforated drum (10) into which fabric goods are loaded. When the drum is accelerated from a relatively low speed, employed in a washing cycle, to a somewhat higher, distribution speed, the input to the control is a "real time" signal which reflects variations in torque required to rotate the drum. The magnitude of these variations is proportional to load unbalance which can cause radial displacement of the drum, machine vibration and damage to its components. The real time signal is averaged. A differential amplifier (24) then subtracts the "average" signal from the "real time" signal, providing an "unbalance torque" signal of alternating polarity. When the "unbalance torque" signal exceeds a given magnitude, reflecting the maximum permissible centrifugal force to be generated by load unbalance, an "unbalance control" signal is generated. The main control (12) of the machine is responsive to this last signal to reduce the rotational speed of the drum.

Title: Biologically absorbable implant material, and method for its preparation
IPC: A61L27/00
Filed: 1988-12-12
Granted: 1993-05-05
Abstract: A biologically absorbable implant material and a method for its preparation are described, which material is intended for filling and/or closing soft tissue cavities and for replacing soft tissue parts. The implant material consists of bone tissue of human or animal origin and is decalcified, and the original protein content of the hard substance of the bone is left; by crosslinking these native proteins with a protein-crosslinking agent, a high degree of elasticity, a good resistance and a pronounced "memory effect" are obtained. The method for its preparation comprises removing the fat from, decalcifying and crosslinking the original proteins, whereupon the material is dried and sterilised.

Title: Improvements in or relating to fabric production
IPC: D04H3/045
Filed: 1988-10-05
Granted: 1993-09-15
Abstract: The invention relates to the production of non-woven fabrics in which an array of weft threads is created and then combined with a substrate, which may in itself comprise a set of warp threads. In the method according to the invention, the array of weft threads is formed by traversing a weft carrier which has a plurality of weft guides, across the weftspace between two sets of weft retainers (300), (302). At the end of each traverse, the weft carrier is jogged, (that is to say moved in the warpwise direction) so that at the next traverse, it lays a further set of weft yarns across the weftspace, and the weft yarns are hooked around the weft retainers. The jogging motion (B) is such, that at each traverse of the weft carrier after the first traverse, some (1b), (2b), (3b), but not all of the laid weft yarns are interdigitated with weft yarns (1a), (2a), (3a) previously laid by the weft carrier or another weft carrier, the remaining weft yarns laid at that traverse being spaced from each other to permit a further set of weft yarns to be interdigitated with them on a subsequent traverse of the or another weft carrier.

Microcomputer (220) accesses registers (212-217) by means of a data bus (222) including address, control and data lines. Microcomputer (220) utilizes digital samples from A/D converter (225) to dynamically detect acoustic feedback and to continuously generate and store in its memory an envelope signal and a valley signal for the transmit and receive voice paths for controlling voice path gain switching. In order to determine when to switch gain between the voice paths, microcomputer (220) compares the envelope signal to the valley signal to detect the presence of voice signals and, if the voice signals are detected for a pre-selected time, the gain of the path in which voice signals have been detected is increased and the gain of the other path is decreased.

Abstract: A method of multipoint communications utilises a protocol in which data messages (10) sent by a primary source are multicast to a plurality of secondary receiving stations (S1..Sn). Each message packet contains a control field comprising a station identifier code (14) and an instruction for the specified station to acknowledge a predetermined number of messages. Each successive message packet comprises a station identifier code which differs in an alterable set cyclical sequence. Thus, acknowledgements of correct receipt of data are taken in a cycle of length L such that in a space of L messages each receiver must acknowledge at least once. In this way the primary source need only keep the L latest messages because all the stations have acknowledged correct receipt of at least up to the current message minus L. The multipoint communications method uses a protocol which can be applied to existing communications networks.
