Title: Hot-runner nozzle
Inventor: WOLFF HANS-MARTIN
IPC: B29C45/27
Filed: 1993-04-14
Abstract: A hot-runner nozzle (1) serves for injecting thermoplastic polymer melt into a mould (2).

Patent DE-4330384-A1 (DE)
Title: Illuminated panel
Inventor: MUELLER HELMUT FRANK OTTOMAR P
IPC: G09F19/14
Filed: 1993-09-08
Abstract: The illuminated panel has at least one transparent screen (10) which has numerous holograms which form area or line patterns (13). Each pattern element is composed of numerous hologram pixels. The holograms in differently coloured fields have been produced using different illumination angles, so that the fields produce different colours for the viewer (15). Incident light (16) makes the patterns (13) appear coloured to the viewer (15), the colour changing as a function of the incidence angle of the light and of the position of the viewer. In the case of reflection holograms, the patterns (13) are visible to the viewer only from the illumination side. The illuminated panel is transparent from the rear. There is, however, also the possibility of making the luminous images visible on both sides of the luminous panel. <IMAGE>

Patent DE-4338978-A1 (DE)
Title: Detecting defective light grid sources and/or receivers
Inventor: BAUMANN ANDREAS
IPC: G01V13/00
Filed: 1993-11-15
Abstract: The light sources and their associated receivers are pref. activated individually in succession and esp. cyclically and the receivers detect whether an optical signal is received from an activated source or not and produce alarm signals when signals are not received. Light from a source reaches not only its receiver but at least one adjacent receiver when there is no obstruction and/or each receiver is illuminated not only by its source but by at least one other. Failure to receive from an activated source is checked by determining whether the receiver adjacent to the associated receiver receives light from the same source or not and/or whether the associated receiver receives light from an adjacent source. An alarm signal is produced if no signal is received. A defined number of reception results is checked to determine whether the presence of an obstruction is probable, in which case the alarm signal is maintained, or if it is not probable, a defect in a source and/or receiver is probable, in which case the alarm signal is turned off and a warning signal generated.

Title: Compact attachment for pre=cooled drinking glasses
Inventor: BECKER WALTER
IPC: A47F7/00
Filed: 1994-01-14
Abstract: The attachment suspends pre-cooled drinking glasses (4) and is positioned on a horizontal bar (1). A row of adjacent cantilevered bolts protrude upwards and forwards at a set angle from the bar. The pitch of the cantilevered bolts is kept the same as the pitch of the conical bases of the glasses so that the drinking glasses are suspended almost vertically. In order to stop the drinking glasses falling out when the door of the cooled sideboard is opened too quickly, the top of the cantilevered bolts can have a rubber ring (3) held in a radial groove so that some part protrudes radially and forms a stop for the drinking glasses.
Patent DE-4406042-A1 (DE)
Title: Rotatable electrical connector arrangement
Inventor: CAMEL ALAN DENIS GILLES
IPC: H01R33/94
Filed: 1994-02-24
Abstract: A rotatable electrical connector arrangement (14) comprises a first electrical connector (16) and a second electrical connector (18) which can be connected to one another and are mounted coaxially with respect to one another in respective housings (24, 112) of the connectors (16, 18). The housing (24) of the first connector (16) contains tubular electrical connections (26, 28) of circular cross-section, which are arranged concentrically. The housing (112) of the second connector (18) contains tubular electrical connections (114, 116) of circular cross-section for connection to the connections (26, 28) of the first connector (16). The two connectors (16, 18) can be connected to one another such that contact springs (40, 56), which project from the connections of the first connector (16), engage in a sliding manner on the inner circumferential surfaces of the connections (114, 116) of the second connector (18), as a result of which the connectors can be twisted relatively about the axes of the connections, the connections of the first connector (16) making permanent electrical contact with the connections of the second connector (18). In an exemplary application, the connector arrangement (14) is arranged between a rotatable spotlight (2) and an adaptor (10) which can be displaced in a sliding manner along rails (12), in order to connect electrical power supply leads to the spotlight while at the same time making it possible for the spotlight to rotate about the axis of the connector arrangement (14). <IMAGE>

Title: Method for generating three-dimensional images
Inventor: TAKEDA SHIRO
IPC: G01N23/04
Filed: 1994-03-16
Abstract: The invention relates to the generation of three-dimensional radiation images, and relates in particular to a method for generating three-dimensional radiation images which permits complete alignment of recorded three-dimensional positions of the images. At least one two-dimensional radiation image of an object is obtained by irradiation with the aid of a beam from a multiplicity of positions which differ from one another. The beam is guided through the object. Two-dimensional pixel data, which designate pixel values in the case of corresponding points on the two-dimensional radiation image are obtained by repeated rasterising of an image in a main rasterisation direction, which intersects a subordinate rasterisation direction, during a sequential movement of the specific subordinate rasterisation direction on the two-dimensional radiation image. Furthermore, three-dimensional pixel data which designate pixel values in accordance with the three-dimensional points within the object are obtained on the basis of the two-dimensional pixel data. <IMAGE>

Title: Radio-controlled alarm clock with digital and symbolic displays
Inventor: GANTER WOLFGANG
IPC: G04G13/02
Filed: 1994-04-26
Abstract: The clock has conventional hands (11) rotating in front of a dial (12), and also a digital display (19) linked to a register (24) in which the set time is stored for comparison (25) with the content of a time-of-day register (26) corrected by signals from a radio receiver (21). A portion (15) of the display carries an alarm-bell symbol (17) which appears continuously in the alarm mode, flashes while th alarm circuit is in a SET mode, and is extinguished when the alarm is inoperative. The SET mode is established by simultaneous operation of two key switches (18,20) whose outputs are AND-gated (23) to a holding circuit (30).
Patent DE-4424754-A1 (DE)
Title: Nuclear mechanical process for determining atomic structures and its application to materials science
Inventor: SCHULTE GERD
IPC: G21G1/04
Filed: 1994-07-02
Abstract: As a result of the novel geometric model on which it is based, the present process of nuclear mechanics supplies for the first time more accurate statements about nuclear and atomic structures, as a result of which inter alia improved "chemical engineering" can be achieved. Likewise, on the basis of this model, an exact calculation of the dipole moments is now possible. Fig. (2) shows the beryllium-9 nuclide consisting of an He-5 and a (spin-compensated) He-4 nuclear ring. The magnetic dipole moments of the non-spin-compensated neutrons (white) are symbolised by arrows - the protons are hatched - the resulting nuclear moment resulting directly from the sum of the individual moments which are to be multiplied by the cosine of the given angles. On the basis of the nuclear ring chain node structures, which are now identified, of lead and uranium, including the correct fission fragment distribution, there is now also the capability of synthesising of as yet unknown elements or isotopes. Furthermore, pointers are given to the finding of non-degenerate isotopes, that is to say chemical elements which deviate from one another in terms of their properties in spite of equal nuclear charge. <IMAGE>
