Title: Surfactant-contg. mineral foliar feeds - causes less leaf scorch than foliar feeds with unaltered surface tension
IPC: C05G3/00
Filed: 1972-11-16
Abstract: Liq. mineral fertilizer (pref. N-mineral fertilizer, e.g. NH4NO3 - urea soln.) suitable as foliar feed, contains a substance which lowers surface tension (pref. alkylbenzene sulphonate) in amt. such that no phytopathogenic scorching occurs. The addn. of small amts. (e.g. 0.001%) of surface active agents in this way prevents leaf scorch, so large amts. of foliar fertilizer can be applied without plant damage.

Title: Pick-up of signals from tape tracks - involves using sensor arranged to inhibit pick-up from adjacent tracks during cross-running
Inventor: BERNECKER OTTO DIPL-PHYS
IPC: G11B5/49
Filed: 1973-07-24
Abstract: The tape tracks scanner has sensors which are arranged in a row across the tape in such a way that there is a sensor on either side of the track which does not pick up any signal. An OR logic circuit for each track is connected through a selection circuit with each of the sensors which blocks ro releases the output of the track sensor, depending on the position of the track, so as to prevent signal errors arising from the cross-running of the tape. Each selection circuit is in two stages linked together by a linking circuit, the first stage incorporating a monostable switch whose function is to determine the position of the tracks.

Title: Bicycle pedal drive system - with reciprocating pedals linked to chain wheel by spring loaded variable drive levers
Inventor: TRAMMELL JUN EARL MONROE
IPC: B62M1/24
Filed: 1973-09-10
Abstract: A simple, effective pedal drive for a bicycle is produced by a set of two reciprocating pedals which are only pressed downwards, and which are linked to the chain wheel by a set of spring loaded, pivotted levers. The levers are linked so that there is no dead point at either end of the pedal travel. The reaction between the pedals and the linking levers is such as to alter with pedal pressure so that the pedals describe a large travel path when lightly pressed, and a smaller path when pressed harder. This means that fast travel is easier on the legs of the cyclist.

Title: Plastics carrier bag mfr. - has stamped tongues folded through two right angles onto future bag wall
Inventor: KRATZERT FRIEDRICH DIPL KFM DR
IPC: B31B160/10

Abstract: The mfr. of a plastics carrier bag with a closure flap laterally welded to the bag walls and with an upward-bevelled front wall as a tongue to be pushed under the flap, and with two handles at the two inner sides of the bag, is from a half-tube length with one long edge projecting beyond the other depending on the flap width, in an intermittent, cyclic process with intermittent transport of the length. Stamped parts or notches are first conventionally stamped out and openings are formed in the projecting part of the wider sheet. Conventionally, two handles are welded on to the inner faces or the upper and lower lengths at the height of the long edge of the narrower length. The handles are then pressed down through the opening into a plane below the rest of the plane of the length and held there during further transport by a rail with andeasily-sliding surface.

Patent DE-2363182-A1 (DE)
Title: Container carrying handle swung clear of filling hole on conveyor - permanent magnet and wire track ensure handle does not obstruct filling process
Inventor: HOJAK RICHARD
IPC: B65B63/00
Filed: 1973-12-19
Abstract: Liquid or powder containers are fed along a roller track conveyor to a filling station. The size of the containers may be such that a carrying handle, which is hinged to the top surface, may overlap the filling hole in the container when folded level with the top surface. Such a situation prevents the insertion of a filling nozzle. To avoid this situation a permanent magnet is hung from a fixed bracket rigidly attached to the side of the conveyor. As a container passes under the magnet the carrying handle is raised to an intermediate position. At this point the handle slides onto a preformed wire track that swings the handle well clear of the filling hole. The wire track is rigidly attached to the magnet carrying arm.
Patent DE-2364196-A1 (DE)

A calculator is connected to the case, which squares or elevates to the third power the displayed distance.
Patent DE-2364900-A1 (DE)
Title: Inverter overcurrent protection with magnetic voltage limiter - has choke to increase overcurrent spike duration to trip thermal fuse
Inventor: BECK ALFONS DIPL ING
IPC: H02M7/48
Filed: 1973-12-28
Abstract: The overcurrent protection for an inverter with magnetic voltage limiter, has a parallel resonant circuit in series with a choke across the output of the magnetic voltage limiter. Several thermal fuses are coupled in series with the loads to form parallel combinations across the voltage limiter output. When a load is short circuited, high but brief current surges can occur, which are often too short duration to trip the fuse. The choke effectively increases the length of these surges typically from 1 m seq. to 3 m sec. for choke values of 30 to 50 microHenry, so that they last long enough to operate the fuse.
Patent DE-2401643-A1 (DE)
Title: Metering pump for sludge pumps on filtering presses - has separate combined diaphragm pumps for additives and waste water
Inventor: STAHLKOPF FRIEDRICH
IPC: F04B13/02
Filed: 1974-01-15
Abstract: The sludge is passed through filter presses where the solids are retained by the filter and the liquids flow away. Since the flow rate through the filter varies depending on the amount of solids retained by the filter the treatment chemicals added to the sludge containing liquid are therefore varied depending on the flow rate. The metering system for adding treatment chemicals to the unfiltered sludge containing liquid in the diagram has two combined piston diaphragm pumps which operate in parallel. One of these pumps delivers the unfiltered sludge containing water and the second pump delivers the unfiltered sludge containing water and the second pump delivers treatment chemicals. Both pumps connect to a common sludge containing water pressure chamber and are driven by a common piston rod. As the filter is blocked by the solids the pressure of the sludge containing water pressure chamber is increased and the throttling diaphragm with a spring is loaded correspondingly and reduces the flow rate to the valve so that less actuating fluid is provided to the control sysem. The chemicals are supplied into the chemicals chamber and transferred through a vave into the pressurised sludge.

Title: Expansion joint for electric conductor rail - with interlocking pivoted plates on support groove to give smooth upper surface
Inventor: GERICHTEN FRANZ JOSEF ING GRAD
IPC: B60M1/30

Title: Forming of inner grooves in thin tubes - involves mandrel and pressing rollers to control flow forming
Inventor: HABAY PIERRE RAYMOND
IPC: B21C37/20
Filed: 1974-04-25
Abstract: Blanks of high-strength steels, such as maraging steel, are used and one end of the blank has a threaded section inserted into a ring. The mandrel which is contoured in correspondence with the grooves in the tube is pushed into the bore of the blank which is coaxial with its outside surface. A steadying ring fits round the outside surface while press rollers engage the chamfered end of the blank. The mandrel is held in the machine arbour and helical grooves may be formed and the wall thickness of the blank may be subject to a reduction of over 50%. The process eliminates costly machining and also improves the fibre structure.
