Title: Reducing organic cpds - with alkali amalgam using two immiscible solvents using eductors contg phase separators
Inventor: WURBS ALFRED DR
IPC: C07C241/02
Filed: 1970-08-08
Abstract: Reducing organic cpds. with alkali amalgam using water or electrolyte and emulsified water-immiscible solvent takes place continuously in contact with an amalgam cell in 2-5, esp. 3 hrs. in consecutively connected eductors. Optimum emulsion mixing ratios are set up by connecting each reductor with a phase-separator through an enclosed closed cycle. The two liquid phases are dissociated in the phase-separator in a way such as to remove desired amounts of the two liquids and supplying them, after emulsifying, to the eductors passed through by amalgam. Pref. with several amalgam cells for each reducing step, only one phase-separator is provided and linked with several eductors of the same reduction step in each gp.

Title: Dockyard mobile crane supply system - has light-duty cable allowing crane free movement and heavy-duty cable for full load current
IPC: B66C13/12
Filed: 1973-07-27
Abstract: The cable supply system for mobile cranes in dockyards etc. has a heavy duty cable to carry the crane full current load and a light duty cable to carry only that amount of power required to drive the crane from one heavy-duty supply point to the next one. This system allows the heavy duty supply points to be spaced farther apart along the water front, since the light-duty cable is very much lighter in weight than a heavy duty cable of comparable length and therefore that much more manageable. When the crane reaches the next heavy duty supply point the heavy duty cable is unwound from its drum ont he crane and connected up.

Title: Safety vehicle with wedge-shaped front and back - features shock indicators and a spherical, self-contained passenger compartment
Inventor: HUCHLER KARL
IPC: B62D39/00
Filed: 1973-09-06
Abstract: Safety vehicle of novel construction where both front and back of the vehicle are wedge-shaped which can be displaced by means of signals from shock indicators which identify shock location, direction and size.

Title: Two stage self regulating ram - ram moves under hydraulic pressure to operating position for pneumatic power stroke
Inventor: GEISEL KARL
IPC: F16H43/00
Filed: 1973-11-21
Abstract: A closed hydraulic circuit is separated from a pneumatic circuit via a membrane. Pneumatic pressure displaces hydraulic fluid into a space above a working ram which moves until it encounters a solid object wherein the pressure in the hydraulic fluid rises and unseats a ball valve which connects the gas pressure directly to a piston which commences the power stroke. A rod is coaxial with the ram and attached to the piston bears on the ram and effects the power stroke. Operation of a regulation valve in the pneumatic pressure supply then retracts the piston and the ram by applying air pressure to their undersides. The system is economical in its consumption of pressurised air.

Title: Optical transmitter for physical spectroscopic studies - with modulated output frequency for information transmission
Inventor: KOPAINSKY JUERGEN DR
IPC: H01S3/107
Filed: 1974-03-15
Abstract: The transmitter employs an organic pigment emitting wide-band coherent radiation, and an electro-optic control unit in an optical resonator which selects a frequency falling to a transmission maximum as a function of the strength of an electrical field which varies the double refraction of a crystal located between polarisers. The pigment is excited to emit continuous radiation and the electrical field is varied as a function of a voltage which modulates the selected frequency for the purpose of information transmission. The effective length of the crystal is such that the free spectral range of the control unit covers the variation of the modulated selected frequency.
