Patent DE-2335430-A1 (DE)
Title: Technique for transmission system checking - within telephone network environment involves transmission of known binary word
Inventor: SCHIMRIGK GERT-UWE DIPL-ING
IPC: G08B29/08
Filed: 1973-07-12
Abstract: The technique is employed at the time when a 'subscriber to subscriber' link is made, and prior to a conversation taking place. The communication link may be checked by transmitting a known Binary word, of known Bit rate, from the initiating subscriber to the remote end. The binary word is checked for authenticity, and degradation at the remote end and assuming that the work is not excessively degraded by noise and interference conversation is allowed over the route. If the word is degraded, the channel is rejected and another channel may be tried.
Patent DE-2339428-A1 (DE)
Title: Connection channel between two different water levels - with flexible damming elements allowing easy movement of boats
Inventor: BAUZIL VINCENT
IPC: E02B7/02
Filed: 1973-08-03
Abstract: The flexible damming system is used for forming a permanent connection between two bodies of water at different levels such as canal sections at different levels. The different water levels are connected by a number of vertical flexible members which are anchored in the channel bottom. These elements restrict the flow from higher levels to lower levels in such a manner that the water depth remains constant in all parts of the canal. Shipping and floating bodies can pass through this damming arrangement by pushing the flexible elements aside during the passage. The flexible elements close immediately after the passage of the boat. The flexible elements can be rod shaped and distributed uniformly over the whole canal width and they can also be arranged horizontally across the canal and combined with vertical members nearer the canal bottom. Vertical members can be hollow so that they can be inflated by compressed air or water under pressure for varying the stiffness of the members and hence the flow conditions in the canal slope. This arrangement eliminates the use of locks.

Title: Circulation system for liq cargo on ships - comprises discharge pump feeding rotatable reaction wheel with nozzles
Inventor: MAUFF HANS-JOACHIM ING GRAD
IPC: B63B27/24
Filed: 1974-04-05
Abstract: The liq. contents of ships tanks (oil, phosphoric acid, etc.) are kept in circulation by a feed pump which discharges the liq. through a rotatable reaction wheel in its delivery line. The pump can be the same as is used for discharging the tank or a stripping pump. The wheel is arranged above the tank bottom and has a number of spray nozzles with a downward and with a radial direction. This prevents the deposition of solids in suspension which in the case of sulphurous particles in oil tanks would lead to rapid corrosion. The power consumption is much less than if stationary nozzles were built in the tank, and the stirring efficiency is better. No mechanical drives are required.

Title: Alternating electrical energy generator - has reciprocating piston or membrane compressing gas and increasing Curie temperature of foils
Inventor: MUNK HEINZ
IPC: H02N11/00
Filed: 1975-05-10
Abstract: A machine for producing alternating electrical energy with permanent magnets supplying a magnetic circuit via closed iron paths which are converted periodically into alternating fluxes. A reciprocating piston (P) or a membrane (M) produces compression heat of a gas, which is used to heat ferro or ferri magnetic foils or sheets, in the enclosed iron magnetic circuit, to their curie temperature. The gas which is compressed and heated in one of the two cylinder chambers (7) by the piston or the diaphragm, flows through slits or other openings in the foils into chambers (9). The foils are heated during this process, and are then cooled by another flow of gas which is compressed in the other cylinder chamber (8) and originating from other chambers (10).

Title: Coat valve for controlling liquid level - has choke channel and uses differential valve and diaphragm pressure to cut supply
Inventor: HUDSON GEORGE D
IPC: F16K31/20
Filed: 1975-05-16
Abstract: The valve supply which is under pressure. The valve has a control chamber which is connected via a choke channel (40) to the fluid supply. One side of the control chamber is formed by a flexible diaphragm (22) on which a valve is mounted which closes the supply line. The area under the diaphragm is larger than the area of the valve. The choke channel runs through the valve. The control chamber is closed by a valve (55) which is mounted on top of a float (46). The valve is opened and closed when the float moves up and down. The movement of the float is guided linearly by a set of guide vanes (48). When the valve mounted on the float is opened, the pressure in the control chamber drops and the main supply valve n28) can open, so that the liquid level can be restored.
