Title: External monitoring of diesel engine injection function - using piezoelectric transducer on injection line triggering stroboscope or oscilloscope
Inventor: BRUECKL SIEGFRIED
IPC: G01M15/04
Filed: 1976-08-31
Abstract: The determination of Diesel engine injection function is carried out dynamically by sensing the pressure wave and/or its resulting noise from outside without having to break into the injection line system. This is effected by applying a transducer sensitive to the external elastic deformation in length or cross-section of the injection line and using the resulting electrical signals to trigger a stroboscope or an oscilloscope. The transducer is pref. a piezo-electric element, particularly a piezo-ceramic element. This gives more positive resolution than acoustic methods and its simplicity lends itself to routine workshop application instead of conventional static injection adjustment.
Patent DE-2647820-A1 (DE)
Title: Electric supply cable for outdoor appliances - is supported from helium filled balloon to avoid entanglement
Inventor: ZINCK EUGEN
IPC: H02G11/00
Filed: 1976-10-22
Abstract: The application is principally to outdoor electrical appliances in a domestic setting, for example lawn mowers or rotary cultivators (4). For appliances connected to mains supply the trailing cable can cause difficulties and accidents. It is therefore proposed to support the cable (2) clear of the ground by hanging it from a ballroom (5). The main connection is typically taken from a suitably placed outdoor socket outlet (1) and supported by the balloon (5) in a sliding clip or ring. As the appliance s moved so the pull on the cable varies the balloon height. A typical maximum altitude is 8 meters.

Title: Polyolefin foam insoles for shoes - by vacuum-shaping a piece of foam and simultaneously punching the shaped sole out
Inventor: POSCH GEORG
IPC: B29C69/00
Filed: 1976-10-25
Abstract: Mfr. comprises charging a piece of heated foam material to a mould and forcing it against the surface of the mould by applying a pressure gradient between upper and lower half-moulds. At the same time, the so-shaped moulding is given the desired contours by punching it out, using the outer edge of one of the half-moulds as punch. By arranging moulds of different sizes, the moulding material is used to fullest advantage, with waste being minimised.
Patent DE-2704660-A1 (DE)
Inventor: GEHMANN WALTER
IPC: F41G1/04
Filed: 1977-02-04
Abstract: The adjustable aperture front sight (4) whose internal diameter can be adjusted by displacing a screw sleeve (15) on a laminate cage (7) has a first transparent disc (11) which is firmly connected to the barrel of the sporting rifle. A second transparent disc (13) is connected to the screw sleeve (15) and is accordingly displaceable with respect to the first disc (11) and the laminate cage (7). Displacing the screw sleeve (15) on a thickening (17) of the laminates of the laminate cage (7) presses together both said laminate cage and the hollow cylinder (5) connected thereto, which reduces both the internal diameter (d) and the external diameter (D) of the aperture front sight (4). This prevents large-area coverage of the target area, irrespective of the setting of the aperture front sight (4), and there is no need for lateral webs in said aperture front sight. <IMAGE>

Title: Electrolyte recovery from rinsing baths in electroplating plant - by feeding rinsing water into plating tank fitted with evaporator
Inventor: STOLLE HANS ING GRAD
IPC: C25D21/18
Filed: 1977-06-29
Abstract: The recovery is achieved by continuously feeding the electrolyte through a vacuum-evaporative cooling plant and then back to the electroplating tank. The water removed from the electrolyte in the evaporative cooling plant is pref. fed into the water rinsing bath(s); and the water in the first rinsing is pref. pumped into the electroplating tank. A closed system can be used in which no contaminated rinsing water is fed into the drains where it could cause environmental pollution. The rinsing water is fed into the electroplating tank, where the dilution effect is counter-balanced by evapn. The result is that a continuous supply of fresh water is not required; and expensive plant for the purificn. of effluent is eliminated.

Title: Machine tool for turning valve spindles - uses three equally spaced radial tools to avoid deflecting spindle under cutting load
Inventor: GERISCH RUDOLF
IPC: B23B29/26
Filed: 1977-07-12
Abstract: When turning long thin workpieces such as valve spindles there is a risk of deflecting the shaft under the load imposed by the cutting tool. This deflection can be avoided by using three cutting tools (4-6) equally spaced around the spindle. The tools are mounted in supports (13-15) fixed to a face plate (8) with a central hole to admit the workpiece. The face plate is bolted to a bracket (9) fixed to the lathe bed (7). This method of machining not only eliminates the deflection of the workpiece but also makes possible a considerable increase in depth of cut, rate of feed and cutting speed.

Title: Multichannel DF appts. with differentiating circuit - squares and adds bearing component signals to derive. ambiguity-reducing voltage
Inventor: SAUR HERMANN
IPC: G01S3/14
Filed: 1977-09-08
Abstract: Two-direction dependent bearing voltages are fed to timing circuits and also to amplifiers. The amplification of the amplifiers is controlled in steps between 0 and 10 dB by a two-point controller. The amplifier output is fed to a squaring stage which may be a four quadrant multiplier. A pilot signal is derived in an adder stage from the squared output voltages of the two squaring stages. This pilot signal is then fed to a differentiating circuit to derive a signal which is used to remove ambiguities in the directional bearing components.
