Title: Spot-welding using spring-loaded electrodes - which rotate under pressure so surface impurities on workpieces are removed
Inventor: REINEL EGON
IPC: B23K11/30
Filed: 1974-04-22
Abstract: Device for the welding together of metal parts, the surfaces of which are coated with oxides and/or other impurities, e.g. rust, scale and/or oil, directly reduces the electrical vol. resistance between the welding electrodes and the metal parts being welded together. The welding electrodes rotate when subjected to the welding pressure. Pref. the electrodes are mounted in threaded bushes so they rotate under pressure and remove the unwanted surface layer(s), pref. using a thread with a coarse pitch, location stops, and a pressure which is a function of the angle of rotation using either a constant or increasing pressure. Used for single- and/or multi- spot welding. The simple device cleans the surfaces of the metal parts and also the electrodes, so the required welding voltage is reduced and electrode life increased.

Title: Mounting for reciprocating church bells - roller carriage to accommodate horizontal forces by further roller mass
Inventor: SCHADE WALTER DR
IPC: F16F15/02
Filed: 1974-06-22
Abstract: The mass (7) is supported for its reciprocating motion on a support (4) secured to a roller carriage (5) mounted on rails (3) which are in turn supported on rollers (2) mounted on a fixed base (1).

Title: Pulse wave length measure - using electrocardiogram signals and photoelectric detection of ear lobe pulse
Inventor: SCHULZE BERND-GUIDO DIPL ING
IPC: G01R25/00
Filed: 1974-12-21
Abstract: The pulse rate measuring system for a traveller responding to traffic conditions by determining the electrocardiogram, measures electrical signals from the R peaks. An initial electrical impulse of constant duration from the peaks and a second electrical impulse of constant duration from the start of the pulse waves at a part of the body other than the ECG tap location, e.g. an ear lobe, are coupled at the output points to the inputs of a subtraction unit which produces differential pulses whose pulse width periodically overlaps the first and second impulses. They are also coupled to a dividing unit over an integrator with one input whose other input is connected to a device producing an analog signal corresponding to the present pulse frequency. The second electrical impulse is from a transmission device with a photoelectric receiver.

Title: Drive for take-up spool of tape information carrier - with tape carried through punching station from supply spool
Inventor: SIEBDRATH DIETMAR
IPC: G06K13/26
Filed: 1975-02-03
Abstract: The arrangement for winding a tape onto a take-up spool is such that linkages to connect the drive motor with the spool are unnecessary and the take-up spool is not constrained to a horizontal position. The tape is carried from a working station (1) via a roller (3) which carries a tape contact lever (4) and then via a guide roller (5) to the take-up spool (6). Its position is such on the tape contact lever that the lever and the spool itself can be swiveled around a common bearing pivot (8). Where the tension of the tape reduces, the lever follows the pull of a spring (9) attached to it. A flange (10) on the spool then meets a friction roller (11) which drives the spool momentarily.
