Title: Jewellery ring refitting mechanism - has tool rack and pinion ram with further low ratio gearing to operating handle
Inventor: KELLER JULIUS
IPC: A44C27/00
Filed: 1975-05-07
Abstract: A rod shaft is provided with toothing to act as a rack. The lower part of the rod carries a hollow tool holder with slits. The outside surface of the holder is conical. On the conical part a forming ring is fitted in such a way, that when the rod moves upwards, the conical part of the forming ring reduces the diameter of the slit tool holder. This diameter decrease is transferred to the jewellery ring introduced into the hollow of the tool holder on a guaged sizing stub. The considerable pressure necessary for the re-sizing is provided from a pinion meshing with a toothed segment with a rather large pitch circle, but the opposite part of the segment has a toothing with a smaller pitch circle. This part meshes with the rack toothing on the ram.

Title: Direct dialling radio and land telephone system - uses release signal to acquire line or channel from translator
Inventor: DALLMANN HORST
IPC: H04W84/02
Filed: 1975-05-24
Abstract: The direct-dialling radio and land telephone system has a transfer unit (1) containing a code converter to translate the dialling code of the land system into the dialling code of the radio system and vice versa.

Title: Coffee percolator heater and evaporator - has incrustation rate reduced by water inlet section smaller than steam outlet
Inventor: BRECHNER ERNST
IPC: A47J31/54
Filed: 1975-07-11
Abstract: The coffee percolator tubular heater is in thermal contact with the tube of the evaporator, and both are set in the hot plate. The design eliminates local overheating spots, and thus enhancing the service life of the heater by minimizing the deposition in the water tube. The reduced water inlet leads to an acceleration of the flow of the relatively cold water, and this contributes to a more uniform precipation of lime. The electroplated hot plate (2) of aluminium holds the tubular heater (3) and the evaporator tube (4). The cross section of the cold water inlet (5) is smaller than the steam outlet (6).

Title: Signal reflection surface for automatic car control - has mounting adjacent driving mirror or rear lights to provide warning output
Inventor: DREWITZ HANS-JUERGEN
IPC: B60K31/00
Filed: 1975-12-20

Title: Quantitative determination of flesh and fat in mixt. - using mass pressed to definite dimensions, as electrical resistance
Inventor: REIFENHAEUSER TONI
IPC: G01N27/04
Filed: 1976-03-03
Abstract: The constituents of a mixture, esp. of flesh and fat, are determined quantitatively by bringing the mass of the mixt. into a definite geometric shape, and using the mass as a resistance, loaded by an a. c. current circuit at constant tension, to measure its conductivity. The minced materials are compressed to the desired shape in a container with two opposing walls of material having an outstanding level of conductivity linked into the circuit. Method is much more simple than de-aerating with water in repeated operations, and esp. much more accurate when small amts. of fat are concerned. The water spoils the appearance of the sample and is useless with mixts. contg. frozen constituents. All the batch is measured so thet irregularities do not matter.
