Patent DE-4103977-A1 (DE)
Inventor: MEESSEN STEFAN DR
IPC: A61M25/06
Filed: 1991-02-09
Abstract: 2.1 The suprapubic percutaneous puncture and drainage of the urinary bladder requires particular dexterity and experience even though it is impossible sufficiently to avoid undesirable application of force, unpleasantness for the patient, the risk of infection and injury or technical faults. 2.2.1 The novel, three-part trocar tip permits force-saving initial puncturing without bruising of tissues as a result of the lancet (1) of particular angular design, an incision restricted to a semi-circle as a result of the groove, sharp knives (2) in order to avoid the infection-promoting punching effect and haemostatic, gentle and therefore conservative expansion of the punctured tissue without the incision wound going beyond a semi-circle as a result of the blunt dilator (3). 2.2.2 The hose (4) which reaches through the trocar shaft into the dilator contributes to the dilation, achieves a tight fit of the tissue even after removal of the trocar and prevents the emergence of blood or liquid beside the hose. A defined slot (5) in the groove-shaped cross-sectionally stable trocar shaft prevents the hose from jumping out due to compressive force without any impairment of the tilting thereof for removal of the trocar after the puncture. 2.3 The device is suitable as a set for single or repeated puncture and drainage and for the introduction of diagnostic, treatment or other equipment into all cavities (including containers for medical liquids) in human and veterinary medicine. <IMAGE>

Title: Domestic oven switch assembly - has components fitted to inner side of the cover with thermal insulation against the appliance
Inventor: KRUEGER WERNER
IPC: F24C7/08
Filed: 1991-07-26
Abstract: The switch assembly for a domestic oven carries the conductors (2) and electrical switch units (3) on the inner side (1') of the switch cover (1). A thermal insulation (5) is between the domestic appliance (4) and the interior of the switch unit. The space (5') between the cover and the thermal insulation (5) is ventilated. The electrical conductors (2) are heat embossed to the rear side (1') of the cover (1). The oven of the domestic appliance (4) generates a vapour outflow to form a suction with heated coolant air (6), to draw fresh air (7) through the unit to cool the switches (3) on the inner side (1') of the cover (1). The fresh air (7) flows in through an upper opening (9) at the cover (1), to move past the switches (3) and out through a lower opening (11). Electronic switches (3) are connected at the inner side (1') of the cover (1) to the electrical conductors (2) by automatied fine soldering. The insulation (5) prevents or reduces heat penetration from the appliance (4) to the interior of the switch assembly and the switches (3). The lower edge surface (12) of the cover (1) has a step (13) to allow vapour and heated coolant air (6) to flow out of the appliance. ADVANTAGE - The assembly requires less space to contain the switch system indicator and wiring, to allow additional equipment at the rear of the switch unit. The thermal insulation also allows the use of electronic components and heat-sensitive plastics units.

Patent DE-4212288-A1 (DE)
Inventor: KLAWUHN MANFRED
IPC: A47J31/06
Filed: 1992-04-11
Abstract: The pressure-filter device (1) consists of a housing section (19) with a piston (25) which can be moved vertically thereinto. On the housing section (19) there is a filter carrier (2) which can rotate horizontally about the pivot axis (4) and is fitted with a filter (29) fillable with ground coffee (39). With the piston (25) lowered into the filter (29) (operative position), the latter forms therewith a pressure chamber (40) enclosing the ground coffee (39) into which the pressurised hot water is forced on the piston side via a line (20) and the prepared espresso beverage flows on the filter side through at least one outlet aperture (38). With the piston (25) raised, the filter carrier (2) with the filter (29) can be pivoted out of the operating region of the piston (25) about a vertical axis (4). Thus the pivoting range of the filter carrier (2) extends from its operative position to its filling position in which the filter (29) is accessible from outside. It is only in the operative position of the filter carrier (2) that the latter is secured in relation to the housing section (19) against vertical movement by supports (43, 42) formed on both the filter carrier (2) and the housing section (19). The system of the invention provides substantially easier handling of the filter (29) in that it is more easily filled with ground coffee (39) and emptied without the need for an operator to hold the filter carrier (2). At the same time, the filter carrier is held firmly in the housing section (19) axially in its operative position without any significant distorsions being caused to these components.
