Title: Marking template for drilling holes in printed circuit boards - has combination of perforated plate with adaptor plate with coordinate raster of holes in perforated plate
Inventor: BAUERNSCHMID GEORG
IPC: B25H7/00
Filed: 1978-12-29
Abstract: The application is to the machining and drilling of additional holes in printed circuit boards, having standardised conductor spacing. Such drilling may become necessary during assembly, and it is uneconomic to return the boards to the machine shop for the required work. A template, or jig, is provided with a hole spacing typically twice that of the conductor spacing on the circuit board. The jig comprises a rectangular board which fits over, and can be definitely registered with, the circuit board. The hole pattern on the jig is offset with respect to the circuit board. The location on the circuit board allows the jig to be fitted in any one of four different positions, thereby covering all possible hole positions on the board. Although the number of hole positions on the jig is much less than that possible on the board the accurate drilling at each possible position is faciliated. The lower number of holes in the jig makes it mechanically stronger, and also assists in preventing drilling through a wrong hole.

Title: Adaptor for electric lamp with screw fitting - allows use of lamp with miniature screw base in standard screw holder
Inventor: LAUSBERG KURT
IPC: H01R33/94
Filed: 1979-01-11
Abstract: The adaptor permits the use of an incandescent lamp (1) with a miniature Edison screw base (E14) in a standard screw (E27) lamp holder (3). The adaptor (2) comprises a standard screw base formed on a hollow bakelite insert. The bore of the insert carries a ring with the small screw thread form, and one electrical contact. The other contact passes through the bakelite base to an external terminal on the standard screw base. To insert a small screw lamp into a standard holder the adaptor is simply screwed onto the lamp, and the assembly then screwed into the holder. On removing the lamp the adaptor remains. It is therefore provided with slots so that it can be unscrewed with an insulated key.

Title: Exhaust pipe for motor vehicle - has pipe bend on end to direct exhaust downward while retaining appearance of circular end
Inventor: BAYER GEORG
IPC: F01N13/08
Filed: 1979-03-03
Abstract: A preformed pipe bend (4) is pushed over the end of the exhaust pipe (1). The bend has a free outlet (5) which is directed downwards onto the road and the closed end (2) of the bend in line with the exhaust pipe is circular or oval.

Title: Cable TV network fault locator - checks the presence of modulated coding frequency signal in the partial band of coding frequencies
Inventor: BAACKMANN DIRK ING GRAD
IPC: H04B17/40

Title: Detector circuit for railway track signals - has tuned circuit with current monitor for detecting presence of track-side information
Inventor: STOECKMANN DIETRICH ING GRAD
IPC: B61L25/04
Filed: 1979-11-07
Abstract: The detector circuit is for use on railway vehicles and provides data relating to the vehicle position along the particular track section. A signal generator or oscillator (G) on the vehicle feeds a resonant circuit (S1) whose standing input current is monitored (D) by a current measuring circuit. Output terminals from the resonant circuit are connected to electrodes (E1,E2), each forming one plate of a capacitor. On the line side, or, more typically between the rails, is the stationary part of the equipment. It comprises electrodes (G1,G2) connected to a circuit (S2) with the same resonant frequency as its counterpart on the train. When the train passes over the track-mounted parts, electrodes (E1,E2,G1,G2) form coupling capacitors (K1,K2) connecting the resonant circuits together. The resultant increase in current from the generator (G) is detected (D) and used to convey the appropriate information to the driver or control apparatus. The moving and stationary electrodes can be angled instead of parallel to assist with coupling. Other metallic objects on the track do not cause the detection of spurious signals.

Title: Pulsed arc welding system - for DC or AC with fully and semi-thyristor rectifier bridges
Inventor: TSCHAKAROV STAMEN JANEV DIPL I
IPC: B23K9/09
Filed: 1980-01-04
Abstract: A pulsed arc welding system is fitted with a thyristorised rectifier bridge for the main welding current and a semi-thyristorised rectifier bridge for the pulsed current. A smoothing choke is connected to the d.c. diagonal of the former. A capacitor is connected to the a.c. diagonal of the latter downstream of the diodes and parallel to the secondary winding of the welding transformer. The secondary winding of the welding transformer (1) is connected by a bus (2) to the a.c. diagonal of the thyristorised rectifier (3,4,5,6) for the main welding current which has a smoothing choke (7) across its d.c. diagonal. The load (8), i.e. the electrode holder and the arc, can be coupled at points C,D to the d.c. diagonal or instead of the bus (2) to the points A,B of the a.c. diagonal. This allows a simple change for welding by a.c. or by d.c. The circuitry has been simplified and the transformer weight has been reduced.

Title: Mechanical speed measurement circuit - uses speed to frequency conveyor and dual interval measurement cycle avoiding pulse interval inversion
Inventor: BADAL JIRI DIPL ING
IPC: G01P3/489
Filed: 1980-03-07
Abstract: A circuit for determining mechanical speed involves a pulse transducer giving an output measurement pulse train with frequency proportional to speed and enables dynamic corrections, including at low speeds, despite l.f. noise. The difficulty of forming a reciprocal time value is overcome. As soon as a measurement train pulse begins a time pulse train count interval is started. After the number of clock pulses counted has reached a defined level the clock pulse-count is then continued until a further defined number of measurement pulses is received. The mechanical speed is then proportional to the ratio of the total number of clock pulses counted and the further number of measurement pulses counted in the second interval.

Title: Simple safety circuit for gas or oil-fired burner - has two relays shutting off fuel supply when flame goes out
Inventor: SCHIMMER HELMUT DR
IPC: F23N5/24
Filed: 1980-04-30
Abstract: The safety circuit has the capacitor (C) of a timing circuit connected to the supply voltage in the quiescent state and disconnected from this voltage when the safety circuit is operated and then connected to a safety relay (R1). The relay has a time constant determined by the capacitor and by the resistance of its coil.

Title: Centrifugal pump for fire fighting - has controller which reduces speed before priming pump is engaged to avoid water hammer
Inventor: GUETTLER ERNST DIPL ING
IPC: F04D15/02
Filed: 1980-05-23
Abstract: The fire fighting pump (1) and its priming pump (2) are driven by a common variable speed motor (4) through a gear box (3). A controller (5) disengages the priming pump by opening a clutch (6) and closing a valve (7) when the main pump discharge pressure (10) reaches a preset value. The speed control lever (11) of the motor is moved by a positioning motor (12) which is activated by the controller. When the discharge pressure falls below the preset value the motor speed is reduced before the priming pump is engaged. This ensures that the priming pump starts gradually without causing water hammer in the main pump.
