Title: Offshore oil drilling platform - having automatically controlled water pumps in feed to extend legs to provide stable footing on uneven sea bed
Inventor: KROPIK ERNST
IPC: E02B17/02
Filed: 1979-09-21
Abstract: Offshore platform rests upon the sea bed in deep water and has feet on the end of extensible legs. The feet have a set of spikes on the underside to ensure anchoring. The platform is raised and lowered by pumping water into the legs using pumps in the feet. The pump action is linked to automatic control sensors in the feet so that if any part of the foot is resting on the surface, pumping continues. There is also a sensor to monitor the angle of inclination of the foot in a 360 deg. span and if the angle exceeds a certain set value, the pumps can be cut out. The system is for use on deep water offshore platforms. The method allows the support feet to follow the contour of the sea bed without the predetermined max. angle being exceeded.

Title: Wind, solar or tidal power generator - has generator output passed to capacitor with controllers establishing level for battery charger
Inventor: BLASER REINHARD DR ING
IPC: H02M7/537
Filed: 1980-09-18
Abstract: The operating system for a circuit for obtaining power from a natural source such as the wind, tides or solar radiation is used for battery charging. The fluctuating voltages from a d.c. generator are applied to a capacitor at the input of a control circuit from which control signals are obtained above and below a determined level to operate a switching unit. This is followed by a further control unit giving a constant output voltage. The first controller includes a hysteresis trigger which establishes the switching levels, and its delay time is regulated by its input voltage. It can include an electronic switch with a FET operated by the presence of a voltage on its control electrode. The second controller includes a dropper circuit supplying signals to a transformer for passing signals of a required amplitude to rectifier for battery charging. A controller establishes the momentary input signals, equalising them with a reference value, and controlling the output and the operation of the chopper.

Title: Multiple die wire drawing machine - has coaxial draw rollers with separate drives to reduce roller wear
Inventor: WOLF JOACHIM
IPC: B21C1/12
Filed: 1980-09-29
Abstract: A multiple die wire drawing bench has draw rollers (3,7) mounted on coaxial shafts (2,6) with each shaft driven by a gear wheel (11,12). The draw roller (3) mounted on the hollow shaft (2) has two different external diameters (4,5) to provide different tangential forces to suit the size of wire being drawn. The draw roller (7) has three such diameters (8-10). By mounting the rollers (3,7) on shafts with separate drives the minimum diameter (8) of the roller (7) is not unduly small. It thus is not subject to a high rate of wear, as is the case with single shaft draw rollers.

Title: Transporter using two endless driven chains - for carrying workpieces continuously through flux soln. prior to hot-dip zinc coating
IPC: C23C2/00

Abstract: A tank filled with a flux soln. is provided with a guide along each longitudinal top edge of the tank; and an endless conveyor chain runs in each guide, at least one of the chains being driven by a motor and chain wheel. A crane is used to lower transverses onto the guides so the traverses travel along a path above the soln. Each traverse has rows of hooks for the suspension of workpieces in the tank. After the workpieces have travelled through the soln., a crane lifts the traverse so the workpieces are removed from the tank. The chains are pref. coupled so they travel together. Each workpiece is immersed in the flux soln. for an adequate time.

Title: Hay-making machine
Inventor: DENI FRANZ
IPC: A01D78/10
Filed: 1981-02-26
Abstract: The rake wheel (5) of the hay-making machine illustrated can be driven in two opposite directions of rotation about an upright axis (2) and is provided with radial tine-carrying arms (1) which, at their free ends, carry double spring tines (10) projecting approximately at right angles and each having two spring turns (7) situated coaxially next to one another and spaced apart and held together by a fixing strap (9). The spring turns (7) of each double spring tine (10) are wound in the same direction. It is thus possible when reversing the direction of rotation of the rake wheel (5) to change the machine over into another working position to dispense with the hitherto necessary refitting or swivelling of the double spring tines (10) on the supporting arms (1). <IMAGE>

Title: Infinitely variable reversible friction-wheel mechanism
Inventor: STELLER DETLEF
IPC: F16H15/10
Filed: 1981-03-19
Abstract: Most mechanisms used for rotational speed variation or gradation and for changing the direction of rotation can be replaced by the mechanism described below. The motor shaft (1) drives the friction wheel (2) and the friction wheel runs on rollers (3) which are mounted close together in the driven wheel (4). The driven wheel is connected to the shaft (5). When the angle of engagement (S) is changed by from 0 DEG  to 90 DEG  to the left or right, the driven wheel begins to rotate. The larger the angle between 0 DEG  and 90 DEG , the closer the speed of the driven wheel comes to the speed of the driving wheel given the corresponding transmission ratio of the wheel diameters. The speed can thus be varied between 1:0 and 1:1. The following relation applies to the speeds: <IMAGE>
