Patent DE-3912774-A1 (DE)
Title: Suspension for steered wheel - with compensating supports to maintain tracking when displaced
Inventor: KLEINSCHMIT EINHARD DIPL ING
IPC: B62D7/16
Filed: 1989-04-19
Abstract: The track rods (24,24') are linked to the steering rod (18) by joints (20,20') which are displaced vertically in opposite directions when the vehicle is steered. This compensates for tracking changes caused by non compensated steering. The track rods are joined to the wheel supports by outer joints (26,26').  The outer joints move in the same direction as the inner joints on each side of the steering to alter the wheel setting. The tracking is maintained when the wheels are steered and when the wheels are displaced by road movements. ADVANTAGE - Stable steering, improved cornering handling.

Title: Standard cement mfr. - using high pressure roller press, sieve and gypsum dehydration heat supply
Inventor: DREIZLER INGO DR
IPC: B02C23/30
Filed: 1989-05-11
Abstract: (A) In standard cement mfr. by co-grinding cement clinker and a sulphate source (esp. gypsum), the novelty is that the cement clinker and the sulphate source are crushed in a high pressure roller press (10) and the finished cement (19) is sepd. from the pressed and deagglomerated material by a sieve (15), the oversize material (20) being returned to the roller press and heat (23) being supplied to the grinding circuit to dehydrate the gypsum to hemihydrate. (B) Also claimed is standard cement mfr., e.g. as in (A), in which dehydration of the gypsum (e.g. chemical or flue gas gypsum) is carried out by a wet chemical process, e.g.  using acids such as H2SO4, HCl, HNO3 or their mixts. ADVANTAGE - The sulphate source is uniformly distributed in the cement and dehydrated, so that a cement of similar quality to that produced in a ball mill can be obtd. without use of a tube mill or ball mill.

Patent DE-4005393-A1 (DE)
Inventor: PIERICK KLAUS PROF DR ING
IPC: G06F11/00
Filed: 1990-02-21
Abstract: This arrangement enables high-resolution screens (HB) with a single pixel selection to be used and avoids the derivation of a check code from the serial picture data stream which is problematic at very high frame buffer read-out frequencies. To form the check code, the picture data, which are entered into the frame refresh buffer (BW1), are entered in parallel to another similar buffer (BW2) which is not followed by a screen and are immediately subsequently read out of the further buffer to a check code generator (P). A check code generated by the check code generator is compared with a previously stored reference code and checked for correspondence in a control processor (SR) requesting the signalling frame display. An error is indicated if there is no correspondence. <IMAGE>
