Title: Hinging door-handle - is on axis parallel to leaf and coupled by levers to transverse lock spindle
IPC: E05B65/10
Filed: 1991-10-30
Abstract: The hinging door-handle has a baseplate fixed to the door at the lock, and retracting the lock bolt to open the door. The lock spindle hinges on a transverse axis in the door against spring action.

The baseplate can have a U-section bearing bracket(12) with base(14) against the door, and in which a first lever(16) turns at right angles to the door. This has a non-round opening accommodating a mating cross-section of the spindle, also a radial shoulder(34), against which a lever(36) on an axis parallel to the door acts, the other arm of this lever forming the handle, the latter opening the door when pressed towards it. ADVANTAGE - Simplicity, and easy opening in panic situation.

Title: Filter element for dialysis machine - consists of activated carbon@ particles subjected to periodic changes of pressure to change position of particles relative to each other
Inventor: WITT FALK
IPC: A61M1/26
Filed: 1992-02-13
Abstract: Gases and liquids from a patient's body are passed through a machine such as a dialyser in order to remove any unwanted or harmful substances. The machine has a filter which is enclosed in a flexible envelope (2). The filter material consists of activated carbon in granular form and is subjected to periodic increases in pressure or to a reduction of pressure below that of the atmosphere.

Title: Inlet guide through walls for household gas - has protective plastics pipe sleeve outside building and protective metal pipe sleeve where it passes through the wall.
IPC: F16L5/14
Filed: 1992-02-15
Abstract: Between the plastics sleeve (21) and metal sleeve (22) there is a screw-tight connection (24) which withstands tensile stresses.  The pipe coupling (14) between the inner plastics pipe (11) outside the building and the metal connecting pipe (12) inside the building (31) is set in the longitudinal area of the protective pipe connection (24). The pipe coupling fills out the radial distance (30) until contacting the inner face (25) of the protective plastics pipe (21) and with its metal circumferential face (26) produces a support face (26) which reinforces the plastics wall (58) of the protective sleeve (21) in this connection. USE/ADVANTAGE - Inlet guide through building wall for household gas. The path of the protective pipe outside the building can be variable adapting to requirements.

Inventor: BREME JOACHIM PROF DR
IPC: C08F2/00
Filed: 1992-10-23
Abstract: A system for the continuous polymerisation of olefinically unsatd. cpds. (I) consists of a tubular reactor which discharges into an apparatus in which unreacted monomers and any oligomers produced are removed immediately after polymerisation, by evaporation under reduced pressure. On the inlet side, at least one reactor section is designed as a heat exchanger with baffles, to give a specific heat exchange surface of at least 80 m2 per m3 free reactor vol., so that the temp. difference between heat exchange medium and reaction mixt. at any point in this section can be limited to not more than 30 K. On the outlet side there is a section which is capable of largely adiabatic operation, ending in a perforated plate which is connected to a vacuum chamber. Also claimed is a process for the continuous radical polymerisation of (I) using a tubular reactor as described above, which can be operated with virtually no back-mixing. USE/ADVANTAGE - Provides a pure (unstirred) tubular reactor system which enables the continuous bulk or soln.

Title: Method for increasing the dielectric strength of a multilayer semiconductor component
Inventor: SCHULZE HANS-JOACHIM DR
IPC: H01L29/74
Filed: 1993-03-01
Abstract: In order to increase the dielectric strength of a semiconductor component which has a sequence of semiconductor layers (1-4) of alternating conductance types and to which a voltage is applied which biasses at least one of the pn-junctions (7) (which separate the layers from one another) in the reverse direction, the carrier (substrate) life is reduced directly by radiation with electrons (14) by means of a radiation mask (15), only in the lateral region (LBr) of the edge termination (12) of this pn-junction, and, at the same time, the braking radiation (18) produced in the radiation mask by the electron radiation is used for objective setting of static and dynamic electrical parameters which depend on the carrier (substrate) life in the central region underneath the radiation mask. The dose of the braking radiation can be adjusted by the material and/or thickness (19) of the radiation mask. <IMAGE>
Patent DE-4306498-A1 (DE)
Inventor: HORST ROEDELBRONN
IPC: E06B9/68
Filed: 1993-03-03
Abstract: The subject matter of the invention is a covering which can be unrolled, as is, in particular, frequently expedient for shading purposes for glass roofs. The covering (5), usually consisting of canvas, is subjected to very high tensile forces during operation, with the result that the yield point of the warp threads is easily exceeded, this having the effect that it can no longer extend in a planar surface. The invention eliminates this disadvantage in that the diameter of the fully wound-up covering roll (1) and of the base of the winding-up reel (3) on which the tension means are seated are of essentially the same size. In this arrangement, in the rolled-in state of the covering, the tensile stressing is virtually 0, whereas the highest tensile-stressing value exists into the stretched-out state. <IMAGE>

Title: Overhead conveyor e.g. for holding CRT type monitor in car repair station - has anti-swing carriage braking devices and telescopic brake rods actuated by force-multiplying levers coupled to relatively low-powered motor
Inventor: MEYER WOLFGANG DIPL ING
IPC: B65G9/00
Filed: 1993-03-17
Abstract: The carriage (4) is movable along a rail (5) and has at each end a brake (8,9) with a friction lining (10,11) brought to bear upon the upper part (6) of the rail by a telescopic rod (12,13) extended by stacks of spring washers (14,15). A motor (16) moves an actuating rod (17) along its guide  causing levers (19-22) to move the brake rods from braking to travelling positions. The telescopic arrangements limit braking force and preclude plastic deformation of any components. ADVANTAGE - System reduces tendency to swing on upper region of rail, and secures stopping of carriage at each position attained in travel.

Title: Method and apparatus for delayed assembly determination
Inventor: PEASE MARK D
IPC: G06F17/50
Filed: 1993-07-27
Abstract: A computer-supported (computer-aided) design auxiliary enables a user to create a draft for realising an electronic circuit. In this sytem, the user creates a draft schematic which specifies a functional description of a draft for an electronic circuit without the necessity of specifying information concerning the assemblies. The system has an assembly arrangement auxiliary for creating a physical assembly for the circuit of the draft schematic. The use of the assembly arrangement auxiliary may be delayed until the draft schematic has been completed and checked. Furthermore, a user of the system has the option of specifying certain information concerning the assembly arrangement as soon as he creates the draft schematic, or of postponing this specification until shortly before the assembly arrangement of the draft (Fig. 1). <IMAGE>

Title: Sewing machine - has horizontal spool case without ejector mechanism
Inventor: MURAMATSU NAOKI
IPC: D05B57/04
Filed: 1993-08-05
