Title: Orthopaedic cervical collar
Inventor: BLAESIUS KLAUS DR
IPC: A61F5/055
Filed: 1989-02-20
Abstract: The invention relates to an orthopaedic cervical collar (1), especially for the extension treatment of the cervical spine, with an upper (2) and a lower (3) collar part (2, 3) which approximately have a U shape and surround parts of the patient's neck. These collar parts (2, 3) can be adjusted in height relative to one another in the direction of the arrow (Pf1) and fixed with the aid of an expansion device. In order to facilitate putting-on or taking-off and comparatively comfortable wearing of the cervical collar (1) by the patient the upper and lower collar parts (2, 3) are open at the front in the chin region in the position of use. At the same time, there is a chin support (4) that can be attached on to the front terminal regions (9) of the upper collar part (2). Thus, the cervical collar (1) supports the head of a patient in the position of use, mainly in the region of the occiput and of the chin, whereas the larynx is kept as free as possible. This is to avoid a feeling of tightness and suffocation of the patient during wearing of the cervical collar (1). (cf. Fig. 1). <IMAGE>

Patent DE-3908610-A1 (DE)
Title: Arrangement for generating compressed air
Inventor: HEGER WERNER ING GRAD
IPC: F04B49/22
Filed: 1989-03-16
Abstract: When a predetermined output pressure is exceeded in known arrangements, the idling phase, in which no compressed air is to be delivered, is brought in by the compression chamber (3) being connected to the suction chamber (4) via a valve arrangement (17) which can be activated by the output pressure. A disadvantage in this respect is that in the idling phase which is thus brought in, and in which compressor work is performed via the admission valve, a considerable amount of energy is consumed. The novel arrangement is intended to ensure that the energy requirement of the compressor in the idling phase is reduced, but without adversely affecting the suction power in the delivery phase. A nonreturn valve (18) is provided with which the suction chamber (4) can be shut off, at least during the idling phase, with respect to the suction line (21) of the compressor. The nonreturn valve (18) can be used in compressed air generators in which, in the idling phase, the compression chamber (3) is connected to the suction chamber (4) and the delivery side is shut off with respect to the consumer. <IMAGE>
Patent DE-3910062-A1 (DE)
Inventor: ILENDA CASMIR STANISLAUS
IPC: C08L51/00
Filed: 1989-03-28
Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.

Patent DE-3913497-A1 (DE)
Title: Annular groove guide band
Inventor: BONGERS DANIEL
IPC: F42B14/02
Filed: 1989-04-25
Abstract: Grooves which run round in the guide band are fitted so that, when firing the projectile,   - the necessary force for forcing the guide band from the projectile into the rifling of the firing barrel is reduced, - the sealing between the projectile and the firing barrel is improved   - the barrel life is increased and   - the friction of the projectile on the barrel wall is reduced.   The diameter of the base of the groove is designed to be slightly smaller than the internal diameter of the firing barrel. These grooves are filled with a lubricant. The grooves can also be alternately filled with a lubricant additive, for example titanium dioxide. When the guide band is forced in, the lubricant and the additive expand outwards, that is to say between the guide band and the barrel wall, and thus produce the abovementioned boundary conditions.

Patent DE-3917448-A1 (DE)
Title: Centrifugally spraying fertiliser from conical container wall aperture - with off-centre stirrer oscillating to break up agglomerations
Inventor: DREYER HEINZ DIPL ING DR
IPC: A01C15/00
Filed: 1989-05-30
Abstract: Fertiliser reaching the conically narrowing end of a container is centrifugally scattered through discharge apertures (28) in the cone wall and the associated vertical outlet. The drive shaft (10) for the centrifugal movement does not coincide with the drive for a rotating bladed stirrer (18), which therefore moves with oscillations. These oscillations, from a stirrer mounted at the level of the discharge apertures, therefore at least periodically direct fertiliser through the apertures (28) for spreading. The stirrer drive shaft may enter the storage container horizontally, and the stirrer may oscilate both vertically and horizontally, with a tumbling motion. ADVANTAGE - Spreader operates continuously, breaking up agglomerations to prevent clogging.
Patent DE-3933938-A1 (DE)
Title: Procedure and appts. for recovery of liposome(s) from lipid soln. - in which positive displacement pump is used to pass soln. through filter elements of increasing size
Inventor: KIEFER HANS
IPC: C12M3/08
Filed: 1989-10-11
Abstract: Liposomes are recovered from a soln. of lipids by drawing the soln. (32) from a vessel (20) with or without the addn. of activating agents and passing it through a coarse filter (11), a finer filter (12) and further filters (13,14) of increasing fineness until the required liposome size has been reached. The appts. used consists of a pump unit (30) and a filter unit (10) with a collecting vessel (20). The filter unit (10) has at least two parallel sections (11-14) of different filter fineness which are selected by a distributor valve (23) and whose outlets are all connected to the common collecting vessel (20). This collecting vessel (20) is connected to the pump unit (30) by a valve (28) and a pipe (31) so that the soln. (32) can be recirculated. USE/ADVANTAGE - Currently used systems for the recovery of liposomes use pressurised air or nitrogen to force the lipid solution through a fine filter of a fixed filter pore size. This process leads to results which are not repeatable and to the prodn. of vesicles of differing sizes which are unsuitable for use as active agent carriers in medical applications. This invention overcomes these difficulties and produces liposomes of uniform and unvarying size.
Patent DE-3935574-A1 (DE)
Inventor: MARTINEZ EDUARDO
IPC: G09G5/28
Filed: 1989-10-25
Abstract: The need for the manual input of skilled technicians is eliminated and the important visual components of each character and the relationship of the visual components of each character with the other characters of the typeface are preserved. The characters are analyzed to determine the visual importance of components in the horizontal and vertical direction which comprise each character and thence the priority of adjustment. Using the visual components determined, starting with the highest priority component, the coordinates describing each character are adjusted according to rules which are dependent upon whether the strokes formed are oriented in the horizontal or vertical direction. The adjustment of the lower priority visual components is dependent on the previously aligned components. The important visual components in the diagonal direction are subsequently adjusted in accordance with similar sized visual components in the horizontal and vertical direction wherein the dimensions of the adjusted horizontal and vertical components are maintained. Methods for adjusting in the X and Y directions are disclosed, along with methods for determining the visual importance of components.

Patent DE-3938311-A1 (DE)
Title: Source audio data generator
Inventor: KUTARAGI KEN
IPC: G10H5/00
Filed: 1989-11-17
Abstract: For the generation of source audio data, the signal data for a preset number of actual scanning values are interpolated for generating several interpolated scanning values. From the actual and interpolated scanning values, those repeated w.r.t. their signal pattern during mutual incorporation are used, whose amplitude are most densely together.  A filter assembly, used for the interpolation, consists of a given number of filter sets of a specified order for  finding digital data for the preset number of interpolating points, lying within a scanning period at a given scanning frequency of the digital input data. Thus interpolation data with a frequency-dependent resolution are generated with the filter sets each having the same amplitude characteristics.

IPC: H04M1/65
Filed: 1989-12-06
Abstract: Modern subscriber equipment usually comprises combinations of different units. In order to simplify the operation of the different units or unit functions for the user, a program-controlled control device is normally disposed in the subscriber equipment. Modern subscriber equipment may on the one hand simplify the work of the user, but on the other hand it also requires specialist knowledge and a great deal of experience, particularly in the light of the ever-increasing range of communications tasks. The new subscriber equipment requires no specialist knowledge on the part of the user for the communication process, since the user can set up a connection to a called subscriber in the normal manner. Only the transmission of the information temporarily stored in the subscriber equipment is performed automatically, where the control devices, in dialogue with one another, control the read-out, transmission and storage of the information. The new subscriber equipment enables the automatic transmission of any temporarily stored information in differently designed communication networks for established connections. <IMAGE>
