Title: Double support-rail for suspension railways - is box-shaped and consists of iron cover plate, two iron L-shaped side girders and two current rails
IPC: E01B25/24
Filed: 1974-03-28
Abstract: The cover plate is horizontal and has holes at regular intervals for screws. Two vertical L-shaped side girders face each other with their L-shaped openings, to form an almost square-shaped box unit. The two bottom ends of the L-shaped side-girders are bent to form the two bearing surfaces which have a hard rubber sleeve. Reinforcement plates are welded or screwed at regular intervals to the inside and outside of the two side-girders which are additionally strengthened by two iron strips of square cross-section welded to the sider-girders in the lengthwise direction of the double rail. The inner surfaces of the side girders each carry a current conductor rail, with porcelain insulators connecting the conductor rail to the side girder inner surface. The cover plate has, at regular intervals, iron attachments for the wire cable hawser.

Title: Peptide synthesis - using arginine N-carboxyanhydride hydrobromide and polyethyleneimine as support
Inventor: PRATZEL HELMUT
IPC: C07K1/02
Filed: 1974-04-08
Abstract: In a process for the synthesis of peptides using the N-carboxyanhydride method with a water soluble support comprising arginylpolyethyleneimine, the support is prepd from arginine N-carboxyanhydride hydrobromide and polyethyleneimine.

Title: Water driven, turbine type power generator - is contained in floating rectangular hull anchored to bottom of stream
Inventor: SCHUSTER JOHANN
IPC: F03B17/06
Filed: 1974-06-21
Abstract: A rectangular casing with a solid bottom, two long sides and two short open ends is anchored to the bottom of a river bed. The upper half carries two drums over which stretches an endless chain which carried blades projecting outwards. The casing floats in the river so that the water level in it is just below the bottom of the chain and the blades projecting from this section of the chain are carried forward by the water flowing through the casing. This turns the chain and the drums which are connected by further chains to electric generators. The inlet of the casing is tapered so that a larger quantity of water enters and is accelerated before reaching the driving mechanism.

Title: Indirect fuel injection system - pump delivery volume is inlet manifold depression dependent
Inventor: NOGUCHI MASAAKI
IPC: F02D1/02
Filed: 1974-09-10
Abstract: The injector pump consists of a plunger actuated by an engine driven cam, whose effective lift is limited by a plate moved between cam push rod and plunger base. The fuel is fed to a chamber above the plunger and delivered to the corresponding injector via a spring loaded delivery valve on the plungers upward stroke. One end of the plunger lift limiting plate is coupled to an eccentre and the opposite end to an inlet manifold depression dependent regulator unit which alters the lift limited plates position relative to the cam push rod and plunger base according to inlet manifold depression strength. The inlet manifold is connected to a diaphragm causing a rod to move which adjusts a potentiometer whose output signal goes to an electronic regulator to adjust a hydraulic pressure in a servo unit. A second potentiometer gives a signal corresponding to the position of the lift limiter plate which is fed to the electronic regulator for comparison with the first potentiometer whose difference regulates the hydraulic servo pressure.
Patent DE-2444308-A1 (DE)
Title: Liquids of different viscosities mixed esp for castable plastics - using baffle wall to spread one liquid as film
Inventor: FRIES BERND
IPC: B29B7/74
Filed: 1974-09-17
Abstract: A method of mixing >=2 liquids, esp. liquid plastics materials having different viscosities, consists of projecting the liquids out of openings; one of the liquids is projected as a jet against a baffle wall, so that it spreads out as a liquid film, while the other liquid is injected perpendicularly or slightly opposed to the flow direction of this liquid film into the film, so that it becomes thoroughly mixed. In one method, the second liquid is injected coaxially as an annular stream surrounding the jet of the first liquid, so that both of them impinge upon the opposite baffle wall. In a second method the second liquid is injected through openings themselves located in the baffle wall. The appts. is used for mixing liquid components for castable plastics. The method enables the components, possessing highly different viscosities, to be thoroughly and accurately mixed without the use of high mixing pressures, thereby considerably simplifying the apparatus and leading to economy.

Title: Bending machine for steel tubes - heats tubes with induction coil prior to bending operation around support rollers
Inventor: SOMOW BORIS STEPANOWITSCH
IPC: B21D7/025
Filed: 1974-10-05
Abstract: A bending machine for large steel tubes has an induction coil assembly (32) which is used to heat the tube section that is being bent. The horizontal tube remains stationary on top of support rollers whilst the induction head (32) moves axially along the tube until a stable temperature required for bending is obtained. When the induction coil stops, hydraulic cylinders start moving the heated tube axially through the bending head against set stops which ensure that the required tube bend is obtained at the correct position. The arrangement is partic. for large dia. hollow tubes which are normally prone to deformation.

Title: Eternal candle - with floating wick carrier and slotted wick shroud to follow molten wax level variations
Inventor: LEHNER HANS
IPC: C11C5/00
Filed: 1974-10-30
Abstract: An eternal candle, filled with a soft wax, has a wick which consists of absorbent and incombustible material, shrouded by a cylinder which extends partly over the wax level and determines the height of the flame. The wick is supported by a spider which follows the alterations of the soft was level. The latter can be raised by replenishing the lost soft wax. This eliminates fluctuations of the flame height over long lighting periods. The wick follows all level changes of the wax and gives the candle the appearance of an ordinary wax candle. The flame height can be adjusted by the relative posn. of wich shroud and wick, independent of the wick height above the wax level.

Title: Oxidn-resistant chromium-aluminium alloy film resistor prodn - by vacuum vapour phase deposition
Inventor: LORENZ HANS PETER DIPL PHYS DR
IPC: H01C17/08
Filed: 1975-03-10
Abstract: In the prodn. of oxidn-resistant resistance material for discrete or integrated electric film resistors by vacuum vapour phase deposition with an electron beam 2-component evaporator onto an insulating substrate, the substrate is heated to max. 530 degrees C and Cr and max. 55 atom % Al are deposited on this. A relatively small amt. of Fe or Zn can also be deposited. The films have the good properties of familiar Cr-Ni alloy films but are more resistant to oxidn. and hence can be loaded more heavily. The third alloy constituent (Fe or Zn) favours the formation of a very dense protective Al2O3 film on the surface, so that any slight internal oxidn. in pure Cr-Al films can be suppressed.

Title: Sealing strip inserted in groove of holder - by expanding groove opening at point of insertion
Inventor: DIXON BERNARD
IPC: E04F21/00
Filed: 1975-11-18
Abstract: Prior to insertion of the strip in a groove of the holder, the opening of the groove at the point of insertion is expanded so as to provide it with a width greater than that of the base of the sealing strip. After insertion, the opening is narrowed at this point to grio the sealing strip. The base of the strip at this point is in an uncompressed state before it is introduced into the groove opening. Pref. the holder is made of deformable material by extrusion, and the strip is inserted while the holder is still in the deformed state after extrusion. After inserting the strip, and after narrowing the groove opening, the holder is stiffened by cooling. The above arrangement avoids the disadvantage of shrinkage of a rubber strip.
