Title: Wheelchair for disabled people
Inventor: HILDEBRAND RUDOLF
IPC: B62B5/04
Filed: 1996-07-18
Abstract: The wheelchair has arm rests (2), fixed on both sides of its seat by a joint (3) to the frame (4). At the front end of the arm rests a braking assembly is arranged, comprising a push rod (5) which is connected to a brake block (6). If force is applied in a certain direction (7) on the arm rest, the push rod is moved downwards causing the brake block to act on the edge of the wheel (1).

Title: Pressure-operated ram for automotive diaphragm clutch
Inventor: TOBIASZ ANDRE
IPC: F16D25/08
Filed: 1996-09-07
Abstract: The ram is particularly for actuating the clutch withdrawal bearing (12) of a spring membrane coupling, having a fixed annular chamber (16) supplied with a medium, under pressure, and enclosed in the radial direction between axial inner and outer cylindrical partitions (18,20). One chamber end is closed by a piston (26) containing an annular mounting (28) between inner and outer cylindrical walls (30,32) and open towards the chamber. The piston slides axially, the inner chamber partition (18) being accommodated in the mounting in the retracted position. The outer mounting wall (32) is accommodated in the chamber. The piston moves right out of the fixed chamber in the extended position. Inner and outer axial cylindrical bushes (42,44) are accommodated between the chamber and mounting walls, and are level with the chamber when the piston is retracted. They slide axially in relation to the piston and chamber, and in the extended position of the piston enclose an annular intermediate chamber (64), which forms an axial extension of the fixed chamber, and which is closed by the piston in the axial direction.
Patent DE-19638705-A1 (DE)
Title: Method of automatically adjusting weight of flow of medium in closed tube system
IPC: G05D7/06
Filed: 1996-09-21
Abstract: The method automatically adjusts the weight of a blockage free flow of a medium which varies over time and has variable consistency. An elastic, round seal seals the feed point of the tube system and also serves to provide volume equalisation, damping and to convey the medium. The medium is conveyed via one or more sloping conduits integrated in the seal. The seal curves outwards when the internal pressure increases. When a predetermined curve is exceeded the seal actuates a switch. The switch blocks further supply via a valve or a pump until the internal pressure falls back to the start pressure selected by adjusting the switch.
Patent DE-19644493-A1 (DE)
Title: Widely-adjustable lens unit
Inventor: ITO TAKAYUKI
IPC: G02B15/163
Filed: 1996-10-25
Abstract: The unit comprises three or more groups of lenses. The first of these, nearest the objective, has positive refraction, as does the second, whereas the third has negative refraction. The groups are movable in the direction of the objective between positions for minimum and maximum focal length. The first group comprises a first negative lens nearest the objective, followed by second and third positive ones. The group characteristics are determined by formulae taking account of the lateral enlargement of the third group at maximum focal length, the focal length of the first group, the Abbe numbers of the first and second lenses in the first group, and the maximum focal length of the complete system. The minimum focal length of the complete system, and the resultant focal length of the first and second lenses in the first group, can also be taken into account.

Title: Link control method between terminals of radio communication network
Inventor: WEINHAPPL JOSEF
IPC: H04W88/14
Filed: 1996-12-20
Abstract: The method establishes a link between two mobile terminals (MS-A,MS-B) via a satellite (UE) in a system with a switching and control ground station (VK) that is linked to network access nodes (VZA,VZB). A useful-channel link message transmitted from such a node to the ground station contains at least one switching point address and a channel address. The control station evaluates this message and decides whether a useful-channel link is to be established in the identified channel between the terminals via the radio transmission unit, whereby the channels are managed.

IPC: F04D29/28
Filed: 1997-01-30
Abstract: The impeller has a width ratio, b2/D of between (0.2,0.6) and a predominant radial throughflow. The radial extent, (D-d1) /D of the radial impeller blade grid (1) reduces from a region of the support wheel (2) to the cover wheel (3). The exit edges (4) of the blades rise outwardly, whereby the grid outlet diameter D increases. The support wheel is inclined against the direction of flow and towards the rotational axis of the impeller. The radial blade lattice begins at the support wheel when the radial ratio, d1/D is greater than or equal to (0.5), and stops when it is greater than or equal to 75.

Title: Optical memory system with interchangeable medium
Inventor: TANI HIROSHI
IPC: G11B21/21
Filed: 1997-03-04
Abstract: The optical memory system includes a control system which moves an objective lens to focus a light beam onto the tracks of a disc. The lens is mounted onto the carriage that moves the beam across tracks and a search control unit moves the light to a target position.  The effect of mechanical offsets in positioning, e.g. due to friction, are minimised by measurements made as bias voltages dependent upon position that are entered into memory and used in the search process. The operation voltage is corrected using the bias voltage.

Patent DE-19720199-A1 (DE)
Inventor: OLDS KEITH ANDREW
IPC: H04W16/12
Filed: 1997-05-14
Abstract: In a cellular communication system which reuses channels in adjacent cells 110, 120, each cell 110 has a base station which allocates a first set of channels to users in a non-overlapping region 111 and a second set of channels to users in an overlapping region 112, 122. Non-overlapping regions of adjacent cells use the same channels whereas in the overlapping region, adjacent cells use non-interfering orthogonal channels. The overlapping region may be partitioned into two areas 112, 122 each having a set of non-interfering orthogonal channels. A subscriber unit may select a non interfering orthogonal channel if interference from adjacent cells occurs or if its position is determined to be in an overlapping region (using GPS for example). The size of the overlapping region may be varied depending on system parameters such as subscriber unit selectivity in the presence of interfering signals.
