Title: Magnetic detecting and direction finding installation - ascertains max. strength of received signal and direction of associated normal surface of receiver coil
Inventor: SCHROEDER BRUNO DIPL ING
IPC: G01V3/10
Filed: 1979-06-02
Abstract: The magnetic locating and direction finding arrangement has two coils at an orthogonal relationship to each other. This coil arrangement consists of transmitter and receiver coils rigidly fixed w.r.t. each other but rotatable about the axis of the transmitter coil. To determine the direction of the detected object the max. strength of the received signal and the direction of the associated normal surface of the receiver coil are ascertained. This is achieved by using a reflector marker mounted centrally to the axis of rotation to provide a directional reference, reflector markers to indicate the direction and a reflector band of 180 degrees to distinguish the selected surface normals. The markers are scanned opto-electronically and the output signals supplied to a counter in a given sequence.

Title: LV lamp holder for traffic lamps - has mains transformer with circular core at least partially surrounding fastening for lamp socket (NL 6.11.80)
Inventor: PEDERSEN JAN BOIE
IPC: F21V23/02
Filed: 1979-06-25
Abstract: A l.v. lamp holder, esp. for traffic signal lamps, consists mainly of a parabolic reflector with a central opening for a lamp socket and a transformer housing behind the reflector. The housing accommodates a transformer providing a relative l.v. for the lamp from the mains supply. The transformer has a circular core with an axis aligning with that of the reflector. It surrounds a retaining fastening matching the lamp socket. The circular core is bounded both in front and behind, by essentially conical surfaces in parallel with each other and with the part of the reflector in front of them. The transformer housing has a wall facing behind and also extending essentially in parallel with the parabolic reflector.

Title: Small slow AC sync. motor - has compressed sleeves as shorting rings and with internal or external rotor
Inventor: MERKLE PAUL
IPC: H02K19/08
Filed: 1979-08-02
Abstract: The motor has the effective region of its poles located at the sides of the stator coil. The short-circuiting rings of the phase-shifted poles are made of copper or another metal exhibiting high conduction and consist of compressed sleeves that slide on in an axial direction. The casing comprises two pot-shaped parts made from sheet metal and joined together by a flange by means of bolts or rivets. The motor may have an internal rotor (in which case the poles are held radially and axially in position by an outer ring) or an external rotor (in which case the poles are held radially in position by an internal part and an extra ring is provided to secure the compressed sleeves in an axial direction).

Title: Drilling underground coal gasification boreholes - at an angle clearing angle of repose of caved ground
Inventor: WENZEL WERNER PROF DR ING
IPC: E21C41/18
Filed: 1979-08-23
Abstract: Boreholes for use in underground gasification systems for coal in situ are drilled at an inclination to the horizontal. The angle is so designed that the bore remains outside the subsidence cone of the angle of repose of the broken overburden strata. This prevents the deflection or kinking of the casings of vertical boreholes which leads to an interruption of the gas supply.

Title: Shortened trailer coupling for lorry - has lateral restriction for drawbar to simulate articulated trailer
Inventor: THIELE BERND
IPC: B62D13/04

Title: Protection of disc stack data recorders - utilises switch closed by small vacuum generated if correct height stack is used
Inventor: FABRIS WILHELM VON
IPC: G11B23/50
Filed: 1979-08-30
Abstract: A magnetic disc stack recording system includes a facility for protection by detection of the height of the stack. Typically, a full stack of discs (3) consists of ten individual discs mounted on a central support (1). A top cover (7) is located over the stack and has a seal (8) around the edge. A clamping ring (11) ensures that only a small air gap exists connecting the inner region (9) and the disc area. When the discs are rotated, air is expelled from the central region and a small vacuum (1.5 mbar) exists in the inner region. This maintains a switch (10) in the closed condition in order to activate the head. If the stack contains a smaller number of discs, the pressure stays high and the switch opens.
Patent DE-2943561-A1 (DE)
Inventor: DOVE FAUSTO
IPC: A24C5/47
Filed: 1979-10-27
Abstract: In the manufacture of filter cigarettes, use is made of connecting strips (3) connecting the tobacco part (4) to the filter unit (1).

Title: Jack spindle drive with self aligning bearing - has coupling hub including curved teeth with centre at bearing centre
Inventor: HULSHOF FRANS
IPC: B66F3/18
Filed: 1980-02-01
Abstract: The jack spindle drive incorporates a self-aligning spindle bearing and a positive coaxial coupling between hollow driving wheel and spindle nut. The coupling hub has curved teeth, the centre of whose curves coincides with that of the spindle bearing. The internal teeth of the coupling can be integral with the driving wheel and there can be a further curved-tooth coupling, by which the spindle is prevented from turning in relation to the load lifted. The tooth curve centres likewise coincide with that of the spherical supporting bearing.

Title: Coal-refuse mixt. utilisation - by pyrolysis followed by crushing and fluidised bed combustion
Inventor: HOELTER HEINZ ING GRAD
IPC: C10J3/66
Filed: 1980-02-05
Abstract: The Parent Patent No. 2943309 described a two-stage process for the pyrolysis of a mixt. of coal and refuse in the first stage and a conversion to fuel gas in the second stage. The second stage is now not performed in a gasification reactor but in a fluidised bed which is charged with the crushed pyrolysis coke. Additional types of fuel can be added before or after the crushing operation. This results in an efficient thermal utilisation of prods. such as slurries which otherwise are not suitable for gasification.

Title: Control circuit for magnetic tape recorder - uses limited voltage drop across resistor to indicate faulty or stationary tape drive
Inventor: CAP HEINRICH DIPL ING
IPC: G11B15/22
Filed: 1980-02-16
Abstract: Thecontrol circuit uses the voltage drop across a resistor to detect when the tape is stationary or when a fault in its drive has occurred during rewind or replay. This voltage drop is limited by a voltage-dependent component whose limit lies above the current for normal faultless operation. A diode or a circuit contg. diodes and a voltage dependent component can be connected in parallel with one of the tape drive motors to ensure a uniform rewing speed. The diode is reverse biased in normal operation. The advantage lies in greater effectiveness and in a reduced number of components.
