Title: Integrated ceramic high-temperature fuel cell
Inventor: WERSING WOLFRAM
IPC: H01M8/2435
Filed: 1993-03-12
Abstract: It is proposed for an integrated high-temperature fuel cell (SOFC [solid oxide fuel cell]) initially to produce at least one planar base body, comprising three mutually adjacent functional layers of the fuel cell, from green sheets, to pile up the latter, if desired with further functional layers, to form a stack and, finally, to press and sinter the latter to form the fuel cell stack. The composite (laminated) bodies, which are presintered if desired, have a higher stability than the corresponding individual layers, with the result that the latter can be made thinner. A special sealing process makes it possible for the fuel cell produced in this way to operate reliably with a high efficiency. <IMAGE>

Title: Glass blowing hollow objects - with mouth of object having mechanically punched constriction prior to double blowing to increase fracture resistance
Inventor: BARBIER RENE
IPC: C03B9/14
Filed: 1993-05-26
Abstract: In the double blowing glass forming process for producing hollow glass bodies with screw necks, the preforming stage is carried out by mechanically punching the glass gob with a tapered shaped punch (26) and a pointed punch (25) which can move inside the tapered punch. This produces a neck with tapered upper section (H1). The internal punch is then lowered to its blowing position and the gob is further shaped by blowing through internal punch (25) to form the lower part (H7) of neck and the internal part of the body (41). The preform is then transported to the final blowing station. Pref. during the final blowing, a device is used which can blow the air into the internal body of the glass object without changing the shape of the mechanically punched upper section (H1). The ID of the constriction (D1) is approx. half the diameter (D) of the bottle mouth. USE/ADVANTAGE - Esp. for blowing cosmetic glass containers. The constricted neck shape makes it less sensitive to fracture.

Patent DE-4418193-A1 (DE)
Title: Clamp for rehabilitation aids etc.
Inventor: MARKWALD MICHAEL
IPC: F16B7/04
Filed: 1994-05-25
Abstract: The clamp is composed of bar shaped elements (4). An I-shaped frame (1) has flanges (2) for the bars plus clamping jaws (9) on the frame crosspiece (3) adapted to the bar endfaces. An interposed clamp piece pressurised via a crosspiece centre opening (6) works at its correspondingly bevelled endfaces (13) with the bevel faces (12) of the jaws. The jaws' ends (14) are faced in non-slip rubber or plastics etc. where they face the bars or are suitably roughened. One frame flange is a slotted rail, pressurised via a wing screw (7) held in a tapped hole (6) in the crosspiece, and the clamp piece adjusts in the plane of the I-frame. The dimensions of the jaws, crosspiece and frame leave only small clearance when off load so the clamp piece responds instantly and actively and the jaws work easily within the crosspiece of the frame for their adjustment, using the bevelled clamp and jaw ends for increasing jaw movement and greater clamping force. The element bars can be fixed to the now-adjustable frame, in all cases providing for repeatability, e.g. armchair or leg rest adjustments for the elderly and disabled.

Patent DE-4422241-A1 (DE)
Inventor: SCHULZE KLAUS DR ING
IPC: F16K17/38
Filed: 1994-06-24
Abstract: The invention concerns a thermal safety fitting in which the closure motion of the obturator is longitudinal with respect to the obturator seat. The aim is to avoid lateral excursions of the obturator, while keeping manufacturing costs and structural size as low as possible. The obturator (12) is held in the open position in the housing (1) on the longitudinal axis of the obturator seat (28) by means of an approximatively U-shaped element (30). The two arms (9) of the U-shaped element (30) are located in the vicinity of a reduced-diameter section (17) of the obturator (12). The part (13) of the U-shaped element (30) joining the two arms (9) rests against a thermosolder (14). If the thermosolder (14) melts, the arms (9) no longer remain in the reduced-diameter section (17) owing to the change in the position of the U-shaped element (30),  and the obturator (12) thus moves into the closed position under the action of a closing spring (24).

Title: Method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials,apparatus for the implementation of the method and material produced thereby
Inventor: WESSLING B
IPC: B01F23/57
Filed: 1981-05-07
Abstract: In a method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials, the materials are vacuum mixed and compressed. According to the invention, the mixtures of synthetic materials and charge materials are already homogeneous in a powder state. They are also resistant without granulation to disaggregation, they are stable and can be shaped as products. Moreover, the rigidity must be obviously high but without fragility. The values of the resistance must approach those of the pure synthetic material. Finally, commercial advantages must be attained. To these purposes, the charge materials must be electrically or electrostatically charged before and/or during the mixing with the synthetic materials. As an alternative, this can also be achieved with the synthetic material and even, for instance, through a continuous stirring within an electric field. The charge remains stable during a long period allowing a previous treatment and a storage of the charge material separated from the mixing operation. A combined loading and mixing reactor, together with an installation (57) for producing a strong grinding of the content, is also part of the invention.
Patent WO-8501158-A1 (WO)
Inventor: BASSLER RALF
IPC: G01P3/46
Filed: 1984-07-24
Abstract: Dans la machine électrique, en particulier un moteur à courant continu ou une génératrice tachymétrique à commutation électrique sans balais, de préférence à excitation magnétique et à entrefer bobiné, les bobines de l'entrefer sont divisées en au moins deux bobines partielles (14a, b à 21a, b) et sont agencées de façon que, dans la zone de croisement des têtes de bobines, les bobines partielles suivantes dans le sens de la périphérie (14 à 21) entourent les bobines partielles précédentes. Lors du couplage en série des bobines partielles, on obtient en moyenne des tensions induites égales, ce qui se traduit, en marche comme moteur, par un fonctionnement silencieux, et en marche comme génératrice, par une petite ondulation de la tension produite. L'ondulation de la tension de mesure induite par la génératrice tachymétrique est presque totalement supprimée si le rotor (11) de la machine est pourvu d'une encoche (31). Ainsi, les crêtes des tensions sinusoïdales induites sont aplaties, ce qui donne une courbe presque trapézoïdale.
