Title: Lighting installation for connection to small generator, e.g. bicycle dynamo - includes light-emitting diode switched by field effect transistor to storage capacitor when rectifier bridge output falls
IPC: B62J6/00
Filed: 1992-07-13
Abstract: A pref. filament lamp (2) is supplied with current from a bridge rectifier (6) of the AC output from the generator (1) while a capacitor (4) of about 1 F is charged. An LED (3) with an 18 mA current-limiting resistor (8) in series is switched on by the FET (9) when the generator is unable to provide sufficient current. The cut-off of the FET on restarting of the generator is accelerated by a 470 nF capacitor (11) and 1 megohm resistor (12) in parallel between its source (S) and gate electrode (G).

Title: Accurate sausage skin handling - using two guide surfaces to centre skin between them and draw it over filling tube
Inventor: MUELLER GERHARD
IPC: A22C11/02
Filed: 1992-07-14
Abstract: To separate sausage skins (1) and fit them over a filling tube (2) to be filled with sausage meat, the skins (1) are taken from a supply container (3) to be drawn over the filling tube (2), while held still between by at least two guide surfaces (5). The guide surfaces (5) are driven at the same speed, while gripping the sausage skin (1) at its circumference. Before feeding the first sausage skin (1), the centering unit (6) is adjusted by setting at least one guide surface (5) to the skin dia., so that the skin (1) is centered to be drawn over the filling tube (2). The sausage skins (1) are washed in the supply container (3). ADVANTAGE - The system centres the sausage skin accurately in front of the filling tube, and passes it cleanly over the tube without distortion.
Patent DE-4224939-A1 (DE)
Inventor: LOEFFLER WALTER
IPC: D01G15/82
Filed: 1992-07-28
Abstract: A carding machine for producing a nonwoven tissue/card sliver is characterized by guiding the fibres along the lower side of the drum (5) and by a waste collecting chamber (2) arranged below the drum and provided with a suction device (4). The drum is equipped with carding elements (22b) and discarding blades (23) substantially located at its lower circumference. The opening drum (7) and taker-in drum (6) are associated to the upper circumference of the drum (5) and are also provided with carding elements (22c, 22b). The supply device (14) at the taker-in drum and the dispensing device (19) at the doffing drum (8) are located at approximately the same level. By guiding the fibres around the lower side of the drum, discarding and in particular evacuating particles of dirt become very simple. The bulky waste collecting chamber (2) allows an uniform suction flow for all dirt discarding elements without affecting the quality of the nonwoven tissue. In addition, the opening drum (7) and the taker-in drum (7) may be arranged at the upper circumference of the drum. A narrow and consequently very compact embodiment is thus obtained.

Title: Gear machine
Inventor: GRIESE KLAUS DIPL ING
IPC: F04C2/18
Filed: 1993-03-26
Abstract: The gear machine according to the invention has two gear wheels meshing with one another, of which the driving gear wheel (14) is driven at a constant angular speed. The driven gear wheel (13) is driven by the former with a harmonically variable gear ratio. In order to prevent, when the angular speed of the driven gear wheel changes during operation, any lift-off, due to inertia, of the driven tooth flank from the driving tooth flank, the mass moment of inertia of the driven gear wheel (13) has been reduced. To this end, the latter, in contrast to conventional gear machines, is mounted rotatably on a shaft (15). <IMAGE>

Title: Arrangement on combined lifting vehicles
Inventor: RIEDER GEORG
IPC: B60P7/13
Filed: 1993-05-08
Abstract: The invention relates to an arrangement on combined lifting vehicles in which the load is taken up and secured against dynamic effects of transportation using a plurality of distributed receiving pins in a defined external position, which, in the event of an interchangeable container being fitted, engage into base parts provided therefor.

Title: Expansion anchor
Inventor: ANISI ABOULHASSAN
IPC: F16B13/06
Filed: 1993-10-01
Abstract: Expansion anchor for anchorage in a bore of a structural part (component). The expansion anchor comprises a shank, which exhibits, at its rear end, means for fastening an article and, at its front end, at least one cross-sectionally reduced section with an adjoining expansion cone, and an expansion sleeve which is pushed over the reduced section. In order to achieve secure fastening in the tension zone (drawing zone), the expansion sleeve is provided with a plurality of through-passages, which are distributed over the circumference. Consequently, the surface area of the sleeve is considerably reduced and lower friction between the expansion cone and the expansion sleeve is achieved during the expansion operation. The through-passages are produced by punching out a sheet-metal strip. The punchings produce a plurality of sharp edges which result in the friction between the bore wall and the expansion sleeve being increased.
