Patent DE-4007883-A1 (DE)
Inventor: NANN EBERHARD DR PHIL
IPC: H01M10/48
Filed: 1990-03-13
Abstract: The invention relates to a method for determining the starting capability of a lead battery. According to the invention, a stable state of the battery is brought about in a discharge cycle and a discharge with a high discharge current is subsequently carried out. The loss in the starting capability, or the starting capability itself, is indicated on the basis of the measured values determined on the stabilised battery and after the high discharge current has flowed, taking into account the temperature, using comparison curves which are stored for the relevant battery type. <IMAGE>

Title: Automatic closure for rainwater downpipe valve - involves float in reception tank connected to release device with closure weight
Inventor: MEHLICH GUENTER
IPC: E04D13/08
Filed: 1990-03-16
Abstract: When the reception tank is full, the rainwater downpipe valve is automatically closed, using a float-operated device (6) which releases the closure process by liberating a closure weight.  This weight is connected to the downpipe valve (4) by a thin rope (2), and when it drops, it pulls the valve into the closure position . The float-operated device has a slide surface which with the aid of a U-profile locates movably on the edge of the reception tank, or is movable by a link and connected to a fixture foot. With the aid of the float, it can be set inclined outwards by the rising water in the tank so that the closure weight slides downwards. USE/ADVANTAGE - To obviate overspill in domestic rainwater tanks.

Title: Hydraulic twin-circuit braking system with wheel-slip control - includes valve unit preventing filling of low-pressure reservoirs at onset of braking on driven wheels
Inventor: MAISCH WOLFGANG DIPL ING DR
IPC: B60T8/175
Filed: 1990-06-02
Abstract: A four-channel hydraulic unit (20) contains control valves (31-34), a return pump (27) with two sections (28, 29) serving the respective circuits, and corresp. low-pressure reservoirs (38, 39).

Title: Coated and ribbed reinforcing rod prodn. - involves rolling ribbing after coating process
Inventor: SCHWAN HERMANN
IPC: C23C2/38
Filed: 1991-02-20
Abstract: A bright steel rod heated to the rolling temp. is coated while passing through a molten metal bath of the same temp.. On leaving the bath the surplus coating is stripped off and the rod is cooled to solidify the coating, while the steel core remains at the rolling temp., so that the metal coating, the alloyed layer and the core are of the same or similar strength. The rod is then rolled to produce the required ribbing, with homogeneous deformation of the above-mentioned three constituent parts of the rod to ensure crack-free coating of uniform thickness. USE/ADVANTAGE - For producing corrosion resistant ribbed reinforcing rods for concrete. Since forming of the ribbing occurs after coating, the intended original geometry of ribbing is preserved, with a resultant better bond to concrete in comparison with reinforcing of this type produced by traditional methods.

Patent DE-4112842-A1 (DE)
Title: Mechanical bonding of blunt ends of two continuous strip materials - comprises rotating store for two rolls, cutting and bonding station and loop store for changing length of strip take=off
Inventor: CLASSEN EGBERT
IPC: B65H19/18
Filed: 1991-04-19
Abstract: Equipment for mechanically bonding the end of a first continuous strip to the start of a second continuous strip has rolls of the strip material mounted on a frame which can be rotated to allow unwinding from either roll. Strip is conveyed through a combined cutting and bonding device and is subsequently taken through a continuously operating loop store which permits continuous haul-off of strip, even when the like is halted briefly for bonding of the two ends. Cutting is performed by a knife moving perp. to the strip movement. The bonding system moves with the knife and comprises an adhesive tape store and application rollers. The continuous strip product is held by pneumatic or hydraulic operated clamps during the cutting and bonding operation. The plant comprises two unwinding stations (1) on a pivoted turning frame (2). Each station holds a roll (6a, 6b) of continuous strip (W). Strip (W) is moved forward to a cutting and bonding station (3) by a conveyor belt (9) to which vacuum is pref. applied. When the end of the first roll (6a) and start of the second roll (6b) are detected by a sensor (22), the conveyor belt (9) and unwinding station (6b) are halted. Pneumatically operated clamps (11, 12, 13, 14) press the overlapping ends of the two strips (W) against supporting surfaces (15, 16). The cutting and bonding station (3) is activated and two circular knives on a baseplate are moved forward to cut off the overlap ends. When the knives move back, suction grips remove the surplus ends. Simultaneously, the bonding arrangement (3) comprising rolls of adhesive tape and application rollers moves forwards controlled by the sensor (22). A strip of adhesive tape is progressively placed over the butt joined ends of the strip (W) on both faces. A perforating knife cuts off the tape after application and moves away from the now joined strip (W). During the cutting and bonding process, the loop store (4) at the end of the line adjusts to the reduced length of strip (W) on the output side of the bonding section (3). Haul-off of the strip material therefore continues without halting the prod. line. USE/ADVANTAGE - The plant is used to cut and bond the butt ends of successive rolls of continuous strip material, without halting the prodn. line.
