Patent DE-2419784-A1 (DE)
Title: Shuttle drive mechanism for loom - comprising rotating shaft having helical blades which drive shuttle
Inventor: WELZEL GUENTER DIPL ING
IPC: D03D47/26
Filed: 1974-04-24
Abstract: A shuttle is picked by contacting with helical blades on a rotating shaft extending across the loom, the shaft being supported on a pair of pref. axially spaced support rollers at an inter. posn. along the shaft. The support rollers have helical ribs which engage the shaft at a posn. between the helical vanes and the support rollers, which are arranged on opposite sides of the axis of the shaft and rotate in opposite directions. Pref. the support rollers are driven via gearing from the shaft itself. The necessity of providing inter. bearings for the shaft is eliminated thereby reducing the cost of the loom. The shaft is prevented from flexing thereby providing more uniform movement of the shuttle.
Patent DE-2421456-A1 (DE)
Title: Articulated crane jib - has main section in two parts at obtuse angle unlocked and straightened for stowage
IPC: B66C23/42
Filed: 1974-05-03
Abstract: The jib is particularly for loading cranes mounted on lorries, having a main section derricking in a vertical plane with two parts joining at an obtuse angle and preferably of different lengths. The free end of the shorter part pivots on a vertical column on the lorry. The parts pivot on each other in a vertical plane where they join and are lockable together. By releasing them from the locked working position and derricking the main section out the angle between the parts is increased. The pivot point between the parts can be at the top, and the locking mechanism at the bottom, the latter incorporating a ram-operated hook. The design allows the overall height of the crane to be reduced in the rest position.

Title: Cam actuated screw cutting mechanism for lathes - has worm and wheel drive actuated by shaft with freewheel clutch
Inventor: THUMM HELMUT ING GRAD
IPC: B23G3/08
Filed: 1974-05-16
Abstract: The screw cutting accessory for a lathe has a cam driven by a dog clutch and a nonjamming drive. This cam is used for feeding a slide against a spring force. The dog clutch connects coaxial coupling shafts. This coupling has free-wheel coupling features and it couples the shafts when the follower spring attempts to rotate the shaft which is connected to the drive in the driving direction of the other shaft. The cam plate actuates a spring loaded follower which actuates a longutidinal slide of the lathe. The screw cutting tool is moved along the workpiece by the cam. At the end of the cutting cycle the tool is withdrawn and returned to the initial position. The cam is generated by a worm and wheel, the worm being actuated by the shaft with coupling.

Title: HV isolator to protect HF signalling lines in railways from HV failure - has HF-continuity foils embedded in dielectric separating line halves
Inventor: GROLL HORST PROF DR ING
IPC: H01P1/04
Filed: 1974-06-21
Abstract: The HV isolator, which is used in waveguide signalling lines in railway systems, protects signalling equipment connected to these HF lines from high voltages that may arise from a shorting failure in the HV system. The waveguide is broken into two portions (1, 2) and a dielectric material is inserted in the break. The dielectric material (3, 4, 5) acts as an HV block and there are metal foils (6, 7, 8, 9) embedded in it to ensure HF continuity. The ends of the metal foils are 3 lambda/4 away from the waveguides -- where lambda is the mean operating wavelength of the signalling system. The isolator is characterised by a high HV isolation and good HF transmission properties.

Title: Hay loader with automatically closing and opening jaws - guided electrical supply cables for jaw actuating motor
Inventor: BANKHAMER JUN VINZENZ
IPC: B66C13/14
Filed: 1974-07-09
Abstract: The hay lift jaw mechanism is lowered and lifted by pulleys and ropes.

Title: O-Methyl-isourea sulphate prodn. - from cyanamide methanol and sulphuric acid with controlled temps and molar ratios
Inventor: WEISS STEFAN DR
IPC: C07C273/00
Filed: 1974-08-10
Abstract: 31-41 pts. wt. of solid cyanamide is added at -10 to +20 degrees C to a stirred, cooled soln. of 50-150 pts. wt. methanol and 100 pts. wt. of conc. sulphuric acid. The product O-methyl isourea bisulphate (I), opt. isolated as the crude prod. impregnated with methanol is reacted with an almost stoichiometric quantity of cyanamide in 50-160 pts. wt. of methanol at +5 to +40 degrees C for 4-72 hrs. to give O-methyl isourea sulphate (II). (I) and (II) are important intermediates which react with amines to form guanidines (e.g. 1,17-biguanidino-9-azaheptadecane sesquisulphate is a fungicide used for disinfection of seeds) or may be used as methylation agents. (II) may be used as guanylation agent for 1,8-diguanidinooctane and 1,10-diguanidinodecane fungicides used against rice smut. The known process for preparation of (II) from cyanamide, methanol and sulphuric acid is a single stage process which takes 4 days and gives yields of about 44% and is unsuitable for industrial scale production. The present process gives almost double the yield in shorter reaction time.

Title: Light alloy composite radiator with extruded profiles - has manifold held by central bolts in channel ribs
Inventor: JACOBS HELMUT
IPC: F28F21/08
Filed: 1974-09-02
Abstract: The radiator made from a light alloy is built-up by joining the faces of extruded heater profiles with longitudinal heating fluid flow channel. The heating fluid manifolds are held on the composite unit by bolts.

Title: Foundry sand separating and recovery machine - including ball mill inside conical double sieve partitioned by baffle disc
Inventor: HEINRICH KLAUS-JUERGEN ING GRA
IPC: B22C5/10
Filed: 1974-09-24
Abstract: A foundry sand recovery machine has a pipe through which the mixt. of sand, pieces of metal etc. is discharged horizontally into a chamber inside a cage in front of a drum rotated at the far end by a drive motor, with spheres inside the drum, forming a ball mill. Around the drum is a truncated cone shaped sieve with a fine outer grid spaced from an intermediate grid, and immediately underneath is a discharge funnel for sand, whilst metal pieces travel forwards due to the slope of the sieve, to fall into a smaller chute at the far end. The cone shaped sieve may be polygonal. About half way along the outside of the ball mill drum is a ring shaped vertical partition which also partitions the sieve so that the charge does not travel along a direct path, to assist the sepg. and grinding action.

Title: DC power supply has two batteries switched in parallel with load - using two transistor switches and base-circuit turn-on switch
Inventor: TANAKA HIROAKI
IPC: H02J1/10
Filed: 1975-12-17
Abstract: The direct current power supply consists of two batteries (1, 2) connected by one terminal to one end of the load (5) and each by its second terminal to the emitter of one of two series switching transistor (3, 4). The collectors of the switching transistors are connected to the load second terminal, and their bases are coupled over separate resistors (6, 7) to a switch (8). The switch connects the batteries first terminals to the base resistors, and thereby turns on the two switching transistor. The connection of two batteries in parallel to a load prevents their charging when two batteries of different charge state are used.

Title: Surface film monitor for oil and fuel - insulating coating on floating electrode is dissolved and circuit established
Inventor: HEIDENREICH ROBERT
IPC: G01N27/12
Filed: 1976-01-15
Abstract: The surface film detector for conducting fluids is particularly useful for monitoring the presence of oil or other fuels in water. The monitor head consists of a float having an upper and lower component (1,5) separated by spacers (6); the weight and buoyancy of the float is such that any floating film of oil can pass between the two halves of the float. Vertical electrodes pass from the upper to the lower float sections, passing through the central zone exposed to surface film (8). One electrode is formed from a bare metal element (4), the second electrode being covered with a material soluble in oil or other fuel. The presence of the fuel film dissolves the insulating coating and an electrical circuit is established through the water between the two electrodes.
