Title: Device with a ski for suitcases
Inventor: GOY ANDREAS
IPC: A45C5/14
Filed: 1987-04-13
Abstract: In suitcases of different sizes, rollers are mounted below the bottom. These rollers are conceived to facilitate handling when transporting the suitcases. Under winter conditions on the roads, the wheels tilt and the suitcase can only be pulled at great effort. The new device with a ski facilitates transporting suitcases when there is snow on the roads. When manufactured with a ski (2), said skis are attached below the suitcase (1). In order to permit sliding, even on uneven surfaces, some springs (3) are mounted between the suitcase (1) and the ski (2). Due to the mounting of a ski (2), satisfactory sliding is guaranteed in winter without the wheels (4) tilting. The suitcase (1) is pulled by means of a telescopic arm (5). The latter can be adjusted individually (6):     - engaged (6a) for rolling on dry roads   - flexible (5a) when the ski slides on snow.   The suitcase on a ski is suitable in winter conditions on roads and paths. <IMAGE>

Title: Joint moulding
Inventor: REHER GEB GRZEGOWSKI
IPC: E04B1/68
Filed: 1987-04-21
Abstract: A prefabricated plastic joint moulding is composed of a part which is to be inserted into the joint and builds up stress, and of sealing lips resting against the surfaces which are to be sealed. In many buildings, joints arise which are of different width and usually vary over their length. Such problem joints cannot be sufficiently sealed by said joint mouldings. The object of the invention is further to develop the joint moulding so that, along with manageable setting, even those joints which exhibit extreme fluctuations in terms of the joint width can be sealed. The object is achieved by a joint moulding having a base part (4), having a bridge part comprising at least one bead part (2, 2'), and having a sealing part (3). If a plurality of bead parts (2') are present, these are added onto the base part (4) in a storey-like manner, and the bead parts (2, 2') are individually connected to one another and to the base part (4) and/or the sealing part (3) via predetermined breaking locations (6). Joint sealing for "problem joints". <IMAGE>

Abstract: A shoe sole including an outsole (5) and an insole (1). The latter includes a plurality of ribs (2) which run along the entire width of the sole, are directed transversely relative to the longitudinal direction of the sole, and are covered at the side facing the foot (10) with a perforated base layer and possibly a covering (6) of leather or fabric. The ribs (2) include a base part which has approximately the shape of a trapezoid, whose shorter base is at the bottom, so that grooves (3) occur between the ribs (2). The insole (1) is located on the upper side of an outsole (5), which upper side faces the foot. The special shape of the ribs (2) results in a reinforced reciprocal rolling effect and consequently in an improved massaging and foot aeration.

Title: Electrically isolated current transformer for measuring DC and AC currents
Inventor: BAUER HARALD
IPC: G01R15/18
Filed: 1987-05-12
Abstract: An electrically isolated current transformer is proposed, which is used for measuring DC and AC currents. For this purpose, the live conductor (12) is surrounded by a thin, ferromagnetic, highly permeable annular core (11) which carries a toroidal coil (13). The toroidal coil (13) is used both for producing an auxiliary voltage field and for producing a measurement voltage. It is connected via a voltage-controlled current source (16) to a triangular waveform generator (15) and, in addition, at one end (13a) to an input of a subtracting amplifier (17) whose other input is connected to the triangular waveform generator (15). The output from the subtracting amplifier (17) is connected to a Schmitt trigger (18) in order to produce a rectangular waveform AC voltage whose duty ratio varies in proportion to the magnitude and direction of the current (i) to be measured, as the measured variable (Figure 1). <IMAGE>

Title: High-performance multiple-chamber fixed bed fermenter for the degradation of biomass and process for operating the same
Inventor: SCHRAUFSTETTER WILFRIED
IPC: C12M1/107
Filed: 1987-05-13
Abstract: A fixed-bed fermenter for the anaerobic degradation of biomass having a vessel, into which biomass to be degraded is fed via a pipe and from which the degraded biomass is conducted away through a pipe and biogas generated is conducted away through a further pipe, and a process for operating the same are described. The vessel (1) of the novel fixed-bed fermenter for the degradation of biomass, viewed in the flow direction, is divided into a first space and a second space situated above this, from which the degraded biomass and the generated gas are conducted away. In this case, the first space is divided into a number of chambers (6), into each of which the biomass to be degraded is introduced discontinuously and in pulses in parallel connection. The pulsed addition of the fresh biomass to be degraded loosens the fixed beds (11, 12) and clumping of the fixed beds by the biomass flowing through is avoided. <IMAGE>

Abstract: A slip-proof element (1) comprises a base material (2) having an array of slip-proof teeth (3) on the upper surface thereof. These teeth are formed by an etching process whereby an upper face (4) of the teeth defines an acute angle with the side face (5) of the teeth. Consequently, the contact surface pressure of an object is relatively small. In the etching process an array of protective material is formed on the etchable substrate and etchant is applied to the substrate whilst the etchant and the substrate are in physical motion relative to one another remaining portions of protective material from the substrate being removed. <IMAGE>

IPC: A63B6/02
Filed: 1988-04-28
Abstract: A dismounting mat has a plurality of layers of different thicknesses, each consisting of a plastic foam material. The thickest layer is designed as the base layer. The base layer is chamfered inwards from top to bottom over the entire height of the base layer. This chamfer is filled in with a circumferential wedge-shaped strip, so that the outer edge ends flush with the top edge of the base layer and extends vertically downwards. Arranged on the base layer is at least one further layer, the further layer having a lesser thickness than the base layer. The further layer has a lesser compressibility than the base layer. Arranged on the further layer is at least one covering layer. The covering layer has a small thickness and a greater compressibility than the further layer. All layers have the same surface dimensions. Arranged on the covering layer is a top coating of, in particular, a nonwoven or a carpeting cover or the like. The foam laminate thus formed is jacketed all round, the jacketing being designed, together with the covering layer and the base layer, to be reinforced.

Abstract: In said reception process and antenna system for mobile reception according to the antenna-selection diversity method, sample signals are taken from individual antenna signals, sequentially subjected to a modulation and added to an antenna signal initially selected at random in order to obtain a cumulative signal which is sent into a reception circuit. The cumulative signal, amplified and selected in the reception circuit, is demodulated and the corresponding most powerful sample signal is thus determined and then used as a criterion for selecting the corresponding most powerful antenna or linear-combination signal. Alternatively or additionally, the interference signal proportion is determined and used as an individual or additional criterion for signal selection.

Abstract: The invention relates to an apparatus for treating cotton contaminated or imbued with honeydew. For this purpose, cotton flocks are fed into a microwave oven, in which the cotton flocks are heated by microwave energy, thus reducing the stickiness or tackiness of the honeydew such that there are no processing disadvantages on subsequent machinery. The microwave oven basically comprises a conveyor belt on which the cotton flocks are conveyed through a passage or channel provided with microwave generators. At the exit or outlet of the microwave oven the cotton flocks are transferred to an opening unit which transfers the cotton flocks into a feed chute or shaft.
