Patent DE-4240878-C1 (DE)
Title: Guide roller with double stay integrated in rubber running surface - has five sixth of roller formed of solid rubber and other sixth being plastics double stay which is lowered into grooves of travel path
Inventor: SCHEIBEL EDWIN
IPC: B60B33/00
Filed: 1992-12-04
Granted: 1994-06-09
Abstract: Five-sixths of the running surface is complete rubber and the other sixth consists of a separate plastics double stay (1) with locating surface which locates on the travel path surface. The double stay is lowered into the travel path grooves. In the rubber running surface (2) a separately produced plastics double stay can be vulcanised, moulded or injected during the prodn. process of the rubber running surface. Alternatively, with rollers with a full plastic running surface the injection moulding mould is so formed that one sixth of the running surface is formed as a double stay with locating surface. USE/ADVANTAGE - For use on supermarket trolleys and platform trolleys. The roller can be economically produced without considerable technical expense and in varying sizes. It also produces a low noise level, and is highly loadable.

Patent DE-4312540-C1 (DE)
Inventor: BASLER WOLFGANG DIPL ING
IPC: C02F1/24
Filed: 1993-04-17
Granted: 1994-10-13
Abstract: The method serves for separating off solids from a suspension and is generally carried out as a flotation method. The suspension (S) to be clarified is fed tangentially from the outside at the periphery of an essentially cylindrical clarifying space (1). By means of hydraulic elements (2) which are applied already before this inflow into the clarifying space, interfering flow phenomena, such as turbulences, are eliminated as far as possible, so that an optimal flow pattern is present in the actual clarifying space (1). The flow is conducted towards the centre of the clarifying space in an essentially spiral path (4), the scum (6) absorbing the substances to be separated off forming on the surface. Various devices for carrying out the method are proposed. <IMAGE>

Title: Electronically operated solenoid apparatus for releasing lock
Inventor: EXALTO JAN PETER
IPC: E05B47/02
Filed: 1996-01-24
Granted: 1997-07-25
Abstract: The apparatus includes a control circuit (AS) through which a signal (Uontgr) to release the lock is fed to its gate. Another input to the gate is fed from a free running oscillator (OSC). The gate output operates a Darlington pair transistor (T1) in series with the solenoid (L1). The oscillator output is also fed via buffer inverters to a reactive time acceleration circuit (RTV). Successive pulses from the oscillator are used to switch the reactive current from an inductor (L2) into a capacitor (C1). The capacitor charges up to a voltage, e.g. 42 volts, which is several times higher than the 9 volt d.c. supply. The series transistor (T1) then stops conducting and the capacitor is discharged into the solenoid coil.
