Title: Surface heater pipe fixing - for civil engineering using synthetic resin fixatives
IPC: E01C11/26
Filed: 1971-04-08
Abstract: Polyester or epoxy resin systems or mortars including such systems are used as embedment for piping fixed to e.g. concrete bearer surfaces for use in heating (deicing) roads, bridges, airfield runways etc. or in heating/cooling of walls, floors or ceilings of buildings.

Title: Removal of carbonate - from alkaline fuel cell
Inventor: JACQUELIN JEAN
IPC: H01M8/06
Filed: 1971-06-24
Abstract: Removal or carbonate - from alkaline fuel cell. In fuel cell working at low temp. with air as combustion gas, the air is cleaned of CO2, before penetrating in the core of the cell by passing through a decarbonater, while a small part of the electrolyte circulating in the cell is decarbonated continuously. The two processes remove substantially all the CO2 in the air prior to use. The operation prevents poisoning of the electrolyte.

Patent DE-2330509-A1 (DE)
Title: Application of natural forces producing a power unit - uses water wheel with flexible immersion tubes
Inventor: EBERLEIN MARTIN
IPC: F03B17/02
Filed: 1973-06-15
Abstract: Energy is obtained from static water by forcefully plunging flexible elliptically shaped hollow tubes into water. The tubes are forced into a round shape after immersion by water pressure, whereby the hollow chamber increases in volume and surfaces with greater force than was required to immerse it. This added force is transmitted to the wheel supporting the tubes. The water depth is inmaterial. The flexible tubes are fitted with internal springs which bring the tubes back to an elipse after surfacing. The tube's outer surface area is always constant. An equal number of flexible tubes are evenly spaced on the wheels rim and connected to the hub by air pipes which also act as spokes. The hub is above the water surface and has a check valve to prevent water entering the tubes. Energy can also be gained by the same principle by the use of a small piston and cylinder and a large piston and cylinder with membranes connected by a push rod.

Title: Machine for fitting outer covers to books - synchronised drive maintains continuous flow of work
Inventor: ANDERS HELMUT
IPC: B42C7/00
Filed: 1973-07-09
Abstract: The cover is carried on bars with their ends supported on an endless chain. The cover passes under a second chain which carries similar bars carrying also rollers on their inner surfaces. As these rollers pass a camplate they are depressed downwards to cause the outer covering material to be folded downwards between two successive bars carried by the lower chain. The drive of the lower chain is synchronised with the upper chain by adjusting a lever in relation to the cam by means of a bolt, thus enabling the process to run continuously.

Patent DE-2353931-A1 (DE)
Title: Combined fire and regulating damper for ventilation systems - has fusible link in main air stream
IPC: A62C2/24
Filed: 1973-10-27
Abstract: The damper has a cylindrical casing with a semi-circular solid wall leaving a semi-circular air passage. Behind the wall are two quadrants pivoting on a central spindle. Their own weight tends to rotate them to shut the air passage and they are kept up behind the wall by wires running over a pulley to a fusible element which is upstream of the damper and in the part of the air stream which is the last to be closed by the falling quadrants. A turnbuckle in the cable linkage enables the open position of the quadrants to be adjusted so that they obscure part of the opening and so regulate the air flow in the open position.

Title: Non-contact measurement of camber and track of vehicle wheels - with auxiliary point reflected on wheel and detected by T.V. recorder
Inventor: SCHIEF ALFRED DR ING
IPC: G01B11/275
Filed: 1973-10-27
Abstract: From the video signal picked up by the television recorder a brief pulse is generated which is used to derive from sawtooth sweep voltages some measuring signals for the x and y directions, which are proportional to the coordinates of the mirror image of the auxiliary point on the photosensitive electrode of the television recorder and which represent a criterion for the direction to be measured. The coordinates can be measured and digitised simultaneously by counting circuits which count a periodic train of pulses in the period between the pulse derived from the video signal and the previous or subsequent rebound of the sawtooth voltages.

Title: De-caffeinating coffee - by liq/liq. extraction of an aqs. coffee extract with liq carbon dioxide
Inventor: VITZHUM OTTO DR RER NAT
IPC: B01D11/02
Filed: 1973-11-19
Abstract: Coffee is decaffeinated by extracting the caffeine from an aqs. coffee extract, produced in known manner, using liq./liq. extraction with liq. CO2, separating the caffeine and recycling the caffeine-free aqs. extract to the extraction zone, wherein the process is repeated with a fresh batch of coffee. Previous processes have included a solvent extraction stage traces of which solvent remain in the aqs. extract which must therefore be stripped before recycling. This is avoided here. The processes are known per se and the (counter-current) extraction with CO2, pref. carried out at just under its critical temp. i.e. 28-30 degrees C. After extraction the CO2 may be removed by sorption on moist sorbents, after which the liq. CO2 is able to be recycled isobarically and isothermally.

Title: Plastics sheet with transverse perforations continuously reeled - and cut along perforation line for starting new reel
Inventor: ROCHLA KURT
IPC: B65H35/10
Filed: 1974-03-26
Abstract: An appts. for transversely cutting continuously supplied sheets of material which posses transverse perforations at regular intervals, esp. for use where the material, e.g., a plastics sheet, is to be reeled onto a spindle and the cutting operation is required at the completion of each reel, when the sheet is to be transferred to the next spindle, is as follows. A cutting rake has prongs which penetrate through the perforations of the sheet at the instant when the row of perforations passes and is to be cut. The cutting interval is pref. determined by a counter which provides the actuating signal when a predetermined number of perforation lines has been counted. The cutting rake pref. has its prongs corresponding to grooves in a roller, around which the sheet is passed as it winds onto the reel. The prongs are flat. An instantaneous cut is produced without stretching of the plastics sheet due to excessive tension. A clean cut is made exactly at a line of perforations, and no wastage results. The rake and grooves operate at a point at which the material offers a high resistance to cutting, e.g. just as the sheet leaves the roller or where it passes around a secondary roller acting as a tensioning roll.
