Inventor: KROEGER WERNER
IPC: E02F9/22
Filed: 1990-08-15
Abstract: The dredger has a grab with two buckets (1,2) which are hinged to a support (3). The buckets (1,2) are opened and closed by hydraulic cylinders (5) which are pivoted to the support (3).

Title: Controlling optimal solar generator working point during battery charging - generating additional voltage when generator maximum efficiency point and battery operating point diverge
Inventor: SEIDLER KLAUS DIPL ING
IPC: G05F1/67
Filed: 1991-01-17
Abstract: Controlling the optimum working point of a solar generator invovles using tansformer power transfer in battery charge mode under different operating conditions. The solar generator is directly connected to the battery vai a decoupling diode. The geneartor is operated with its maximum temp.-dependent no-load voltage in the region of the battery charge and voltage. In the low temp. region and for a not fully charged battery, the generator voltage at the maximum efficiency operating point is approximately equal to the battery votlage. An additional voltage is generated in series with the generator voltage to operate the generator at its maximum efficiency when the battery operating point and maximum efficiency point diverge. ADVANTAGE - Ratio of generated to useful power at maximum efficiency point is increased and hence efficiency in battery charge mode is increased.

Title: Speed regulation circuit for CD player accepting two sizes of disc - distinguishes between standard and mini discs by optical detector to select one of two operating conditions
Inventor: BAAS DIETER
IPC: G11B19/22
Filed: 1991-02-09

Patent DE-4109739-A1 (DE)
Inventor: KROGGEL MATTHIAS DR
IPC: C08F8/28
Filed: 1991-03-25
Abstract: The invention relates to acetals of polyvinyl alcohol (PVAL) which contain vinyloxoacetal units of the formula I which are derived from keto-containing aldehydes (oxoalkanals) and can be crosslinked via their keto groups by means of hydrazine or polyfunctional hydrazine derivatives or polyfunctional carboxylic acid hydrazides to give high-molecular-weight products having a variable property profile. It is also possible for mixed acetals with keto-free aldehydes to be prepared and crosslinked via the keto groups of the vinyloxoacetal units. The preparation of vinyloxoacetal unit-containing products from PVALs and oxoalkanals or low-molecular-weight acetals of oxoalkanals is preferably carried out in aqueous or organic media with acid catalysis. For the preferred use of polyvinyloxoacetals according to the invention as polymeric binders and coating compositions, they can preferably be employed, for a number of areas of application, in dissolved or dispersed form with addition of the abovementioned crosslinking agents, it being possible for the crosslinking to be carried out during or after drying of the solutions or dispersions with formation of sparingly soluble and swellable or insoluble and non-swellable polymeric modifications having surprisingly advantageous properties.

Inventor: BERGEN ERNST-PETER VON DIPL IN
IPC: B63H23/32
Filed: 1991-05-25
Abstract: The ship's propeller is driven by a shaft (4) which passes through an opening (3) in the stern of the ship.
