Patent DE-2634911-A1 (DE)
Title: Control system for transfer line with presses - has electronic inspection system for detecting defects and transferring workpieces
Inventor: TRAEDER KURT DIPL ING
IPC: B21D43/02
Filed: 1976-08-03
Abstract: The control system for material and workpiece transport between machining stations is used for presses, especially for gang presses and linked machine tools. A press is switched off in case of a defect and the defect is indicated. The machine is restarted automatically after acknowledgement by the operator. The defective component runs through all further stations without switching off any stations. For each workpiece inspection station an output of an associated NOR element is coupled in parallel to inputs of input signal storage. An input of this NOR element is coupled to inverse output of cam actuated switch and other inputs are coupled to direct output of signal storage.
Patent DE-2637757-A1 (DE)
Title: Form tool for cutting screw thread - has two sets of teeth arranged symmetrically for easy interchange
Inventor: SCHUDZICH HELMUT
IPC: B23B27/06
Filed: 1976-08-21
Abstract: The tool holder (1) is provided with a recess (3) to receive the form tool (2). The form tool is symmetrical about the axis (12) which passes through the centre of the clamping hole (7). Two teeth (14') project beyond the edge of the tool holder so that they cut a thread with its axis parallel to the tool holder. The other pair of teeth (14) lie within the recess (3) and are thus protected from damage. When the pair of teeth (14') become worn, the form tool (2) can be inverted and because of its symmetry the second pair of teeth are correctly positioned to continue cutting the thread with the same degree of precision.
Patent DE-2638296-A1 (DE)
Title: Slide with stiff transparent cover stuck to it - has pressure applied through rounded block of elastic material
Inventor: BETHMANN GUNTRAM
IPC: G03D15/10
Filed: 1976-08-25
Abstract: The slide (8) is placed face upwards on the base (1b) of the press, a drop of adhesive (10) is put in the middle of its surface, a stiffer, transparent cover (9) is placed over, and pressure applied through a rounded block (7) of elastic material. The method is inexpensive and easy to merchandise. The rounded block (7) is typically of foamed plastic and attached to a press rod (5) supported by an angular bracket (6), and has its upper tip pivoted to a lever arm (3), the upper end of which terminates in a hand lever (3a). The lower end is held down to the base by a spring (4) to the base (1).
Patent DE-2639284-A1 (DE)
Title: Shop or store security system - uses two magnetic fields applied to security zone to detect passage of magnetic element on goods and sound alarm
Inventor: MEIR FRANZ DIPL ING
IPC: G08B13/24
Filed: 1976-09-01
Abstract: The method is designed in particular for the delection of goods (3) stolen from counters in a store. The method uses two alternating magnetic fields which are used to sweep the surveillance zone (2). These fields act on marking elements (4) attached to the stolen goods which produce and radiate at least a frequency different to that of the alternating field frequencies. In order to counteract mutual influence and to suppress formation of harmonic frequencies or modulation attributable to simple coupling, the supply to the magnetic field generators is effected by an applied current. Whilst because of the non linearity of the marking element, an harmonic signal is produced which represents at least twice or a multiple of the base or excitation frequency.
Patent DE-2643776-A1 (DE)
Title: Separating roller set for boards leaving cutting unit - comprises pair of roller wheels placed at angle to one another
Inventor: MUELLER HERMANN
IPC: B65G47/71
Filed: 1976-09-29
Abstract: Boards or planks produced by cutting-up larger trunks etc need to be separated from one another on emerging from the cutting unit. This is achieved using a pair of roller wheels (1) whose rotational, horizontal, axes lie at an obtuse angle to one another. The edges (12) of the wheels facing the oncoming stack of boards are closer to one another than those on the outlet side. The tops parts of the wheel circumferences project through a hole in the surface (4) along which the stacked boards travel. The sliding surface (4) is swivable about a horizontal rotational axis on the inlet side while on the outlet side vertically acting compressed air cylinder presses on the bottom end of the surface.

Title: Defective nuclear reactor fuel rod localiser - has deflecting springs with strain gauges on fingers with ultrasonic test heads
Inventor: ZINSSMEISTER ROLF C ING GRAD
IPC: G21C17/07
Filed: 1976-12-30
Abstract: Defective fuel rods within fuel elements of water-cooled nuclear reactors are localised by introducing a frame with comb-like fingers which have ultrasonic test heads at the free ends. Deflecting springs with srain gauges are attached to the sizes of the free finger ends. Their distance is at least equal to the normal gap between the fuel rods. A processor compares the deflection with the normal value. This device can be used to localised in the one operation both rods with an influx of water and rods which reveal any deformation.

Title: Cis-polyisoprene prodn. - by soln. polymerisation of isoprene! with a reaction prod. of titanium tetra:chloride and organo aluminium cpd. as stereoregular catalyst
Inventor: LIAKUMOVITSCH ALEKSANDR GRIGOR
IPC: C08F136/08
Filed: 1977-01-18
Abstract: Cis-polyisoprene is made by polymerising isoprene in an polar hydrocarbon solvent medium at 0-60 degrees C in the presence of 0.2 - 0.7 pts. wt. (per 100 pts. wt. isoprene) of a catalyst consisting of a 1:1.5 to 1:1.1 (mol) reaction prod. of TiCl4 and an inter cyclic organoaluminium cpd. of formula in which R (same or different) are H or CH3. The catalyst gives high yields of polymer with a high cis-polyisoprene content, a high mol.wt. and low gel content. The (I) and (II) do not ignite in air, and are thus safe to use than trialkylaluminium cpds. The cis-polyisoprene prods. are useful as raw materials in the tyre industry and for the prodn. of technical rubber prods..
Patent DE-2709640-A1 (DE)
Title: Forklift height preselection equipment - has punched tape passing round star wheel driving proportional signal emitter
Inventor: PFEIL MARTIN
IPC: B66F9/075
Filed: 1977-03-05
Abstract: The equipment preselects a number of lifting heights for a slide travelling up and down a mast, being particularly for a forklift truck or shelf-loading machine. A measuring tape is anchored at one end to the slide, while the other end is wound in by a spring-loaded roller, and initiates the operation for picking up or setting down the load on reaching the selected height. The tape (9) is punched (9a) or toothed, and passes from the roller (12) round a spider wheel (5) driving an emitter (22) generating an electrical signal proportional to the distance travelled. A pushbutton selects a similar signal of predetermined value in a preselector unit and when a comparator unit detects two identical signals it initiates the picking-up or setting-down operation.

Title: Clarifying tank for waste water treatment - with central air lift pump in settling cone as sludge stirring mechanism
Inventor: THUENER FRIEDRICH
IPC: B01D21/00

Abstract: A clarifying device for a water treatment plant has a clarifying section and a settling cone arranged in the same tank. The stirring mechanism in the settling cone consists of an air lift pump. Its pump tube includes two separate pipes in the centre line of the tank which end in the plane dividing the clarifying from the settling section. The waste air is carried away in a central pipe through the clarifying section which overlaps with its bottom end the top pump tube. The stirring mechanism does not disturb the clarifying process, yet it keeps a homogeneous sludge in circulation even during its discharge operation.

Title: Anti-rust treatment of metal surfaces - by cleaning, coating with impact glue and fusing-on plastics waste particles
Inventor: WEISS ERICH
IPC: B05D7/14
Filed: 1978-03-29
Abstract: Plastics scrap is re-used for coating metal components e.g. motor vehicle body parts, to protect them permanently from the degradative action of water, atmospheric oxygen, etc. thus preventing and/or stopping deterioration by rust. The metal surfaces are thoroughly cleaned and coated with contact adhesive. Plastics scrap is then distributed over the thus-prepared surface(s) and firmly fused-on with aid of heatable electric appliances e.g. soldering iron or flat iron. The resulting protective coating is said to adhere so firmly that it cannot be removed even by hammer-blows.
