Patent DE-2832149-A1 (DE)
Title: Safe animal stunning circuit - uses pulsed DC stun voltages and measures resistance between electrodes
Inventor: GEHL WILFRIED
IPC: H05C1/04
Filed: 1978-07-21
Abstract: The stunning circuit has a sensor measuring the electrical resistance between two electrodes and initiating the application of the stun voltage to the electrodes when the resistance measured lies below a given limit. The stun voltage is a pulsed d.c. voltage whose mark/space ratio is less than 1. A monitor (22) detects when a stun voltage is present when it should not be in the circuit formed by the electrode terminals (27, 28), the control unit (20) that applies the stun voltage and the detector (21). The advantage lies in the user's being protected from the stun voltage.

Title: Fibre pen and mfg. process - whereby the extruded plastic tube enclosing the fibre core has spiral air channels
Inventor: MIDORIKAWA YOSHIO
IPC: B43K8/02
Filed: 1978-09-08
Abstract: A fibre pen with integral tip and ink reservoir is mfd. by compressing a bundle of fibres and surrounding them with an extruded plastic tube with longitudinal or spiral air passages in its inner surface. Trapezoidal section and spiral alignment prevent fibres from blocking the air passages. The plastic-encased fibre bundle is cut to pen lengths and immersed in urethan-prepolymer and then stored for formation of a hard tip.

Patent DE-2850031-A1 (DE)
Title: Revolution rate sensor for direct drive motor - uses summing of 90 degree phase-shifted field coil signals
Inventor: BUCKNER IAN WILFRID
IPC: G01P3/46
Filed: 1978-11-17
Abstract: A revolution rate sensor is used for measurement of the speed of an electric motor. It uses two sensing coils placed in the motor field and giving output signals with a 90 deg. phase difference. The output signals are conbimed in a summing unit to give an output signal proportional to revolution rate. No smoothing of the derived signals is necessary, thus enabling use of simpler servo circuits with a wider bandwidth per number of motor poles than alternative systems. The sensor is applicable in record players with direct drive motors.

(I) is a yellow, odourless, crystalline solid with a bitter taste. It is soluble in acid media, partly soluble in polar hydroxylic solvents and insoluble in apolar solvent. Its Uv spectrum in 0.1 N HCl is identical to that of pyroxal-5-phosphate but its IR spectrum lacks free OH vibrations at 3700 cm-1. (I) does not decompose below 250 degrees C and contains 9.4% Mg (by complexometric titration).

Title: Fuel injection pump for IC engine - has throttling orifice in piston to increase duration of injection at idling speeds
Inventor: PRESCHER KARLHEINZ DR ING
IPC: F02M45/06
Filed: 1979-02-21
Abstract: A piston reciprocating in a cylinder is driven by a cam-shaft from the engine. The piston has a profiled groove and is rotated by the fuel regulator so that the endge of groove uncovers a relief port after the required quantify has been delivered. A further passage through the piston connects the discharge and suction sides of the piston. This passage contains a throttling orifice (Db). The free cross section of the orifice is varied as the piston is rotated and also varies with the piston stroke. It varies the relation between duration of injection and quantity between full load and idling.

Title: Safety binding for long distance ski - includes front binding section providing side hold to front of boot sole with separate release devices
Inventor: SCHECK GEORG
IPC: A63C9/20
Filed: 1979-02-24
Abstract: Long distance ski safety binding with a front binding section holding the front end of the boot sole in a tensioned condition and turable around an axis vertical to the ski against a release resistance or alterantively permitting a corresponding turning movement of the tensioned booth. The safety binding is equipped with a release mechanism which operates to overcome the release resistance when an excessive torsion force is applied to the skiboot. The booth holding devices n16, 17) which firmly hold a projection of the front boot sole under tension form a part of the binding section and are held under full holding tension by the release devices (24) producing the release resistance which are separate from the boot holding devices of the binding section. Only after that turning angle has been exceeded is the tension released to open the release devices and to free the skiboot.

Inventor: STETTER KARL-HEINZ DIPL CHEM D
IPC: C11B11/00
Filed: 1979-04-19
Abstract: Bleaching of montan wax (opt. mixed with other waxes) is carried out by (a) rapidly adding the molten wax to a chromic acid soln. contg. 60-140 g/l CrO3, 400-600 g/l total H2SO4 and 300-500 g/l free H2SO4 at elevated temp., and (b) agitating the mixt. and simultaneously distilling off H2O in an amt. such that the free H2SO4 content remains >=200 g/l. Compared with prior art processes, the process can be completed in a shorter time with less wax degradation and thus lower chromic acid consumption, using smaller reactors without equipment for vapour recycle or H2O addn.

Title: Spark erosion machine for mfg. spark erosion electrodes - esp. rod electrodes of very small dia. employed for drilling holes
IPC: B23H1/04
Filed: 1979-05-21
Abstract: Machine consists of a frame carrying two rolls sepd. by a gap and driven in opposite directions and the electrode which is to be spark eroded to its final desired size is fed through the roll gap. A voltage is created between the electrode and the two rolls to cause the required erosion. When the electrode is round, it is pref. rotated while it is driven through the roll gap; but electrodes with a rectangular or square cross-section are pref. fed vertically through the roll gap without being rotated. Used when drilling e.g. numerous holes using electrodes with a cross-section below 0.1 mm, the electrode must possess an accurate size, which is normally achieved via a grinding machine. The invention provides a portable machine which can be placed on the worktable of a spark erosion machine for dressing the electrodes.
Patent DE-2925070-A1 (DE)
Inventor: WUESTNER FRIEDRICH
IPC: C03B37/16
Filed: 1979-06-21
Abstract: A method and a device for cutting or breaking a plurality of light waveguides which are contained in a cable characterized by clamping each of the light waveguides at spaced points to hold a portion of the waveguides between said points parallel to each other, positioning the light waveguides extending between the points over an anvil with each of the light waveguides being parallel to one another, applying a common tension force to each of the waveguides at the other side of the anvil, applying a vertical force to each of the waveguides at a point on one side of the anvil to apply an axial prestress to each of the waveguides extending across the anvil, and notching each of the prestressed light waveguides at a point in contact with the anvil to cause separation of each of the waveguides at its notch.
Patent DE-2930121-A1 (DE)
Inventor: GIESINGER HANS
IPC: B05B7/14
Filed: 1979-07-25
Abstract: When the type of powder is changed, there is the risk that powder residues of the powder previously used will mix with the new powder and that coating faults will thereby occur. This is avoided in that a plurality of feedlines (13, 17, 14, 18) open into a common delivery line (20) and selectively actuable closing devices (15, 16) are located in the feedlines. Scavenging gas for cleaning the lines is introduced downstream of the closing devices (15, 16). Because the gas is introduced in a turbulent manner, a homogenisation of the coating material is achieved during operation, before it is atomised. The spray method and the apparatus necessary for this are simplified and therefore more economical in operation. <IMAGE>

Title: Monitoring of eye movement - has IR LED applied to lower eyelid and TV camera
Inventor: DITTEL GERHARD
IPC: A61B3/113
Filed: 1979-08-31
Abstract: Present methods of recording eye movement tend to stimulate tear secretion which produces undesirable reflections and, in addition, present the problem of the 'ellipticity of pupil'. These problems are surmounted by visualising the pupil solely by a single l.e.d. A small infra-red l.e.d. with a power of less than 15 mW is applied to the lower eyelid. The light is scattered within the eyeball and passes through the pupil to an infra-red video camera. The diode can be placed so that the image of the pupil is either circular or elliptical. Suitable adjustment of contrast and brightness of the TV-monitor enables imaging of the pupil in isolation.
