Title: Well casing butt welding clamp - with jaws on hollow rod cones for insertion inside casing bore
Inventor: SACHARNOW WASILIJ ALEXEEWITSCH
IPC: B23K11/093

Title: Combined film transport and shutter tensioning camera lever - has a differential slip coupling to the film spool gear
Inventor: HOEPFNER CLEMENS
IPC: G03B17/42
Filed: 1973-08-10
Abstract: The design is intended to match the constant extent of the lever or slider movement to the varying amount of spool rotation required. The lever or slide is fitted with a pull bar which is pressed into close contact with a toothed rack. The rack drives a set of gears which rotate the film take-up spool. The pull bar carries a guide pin in contact with an angled guide face in the rack. When a perforation probe locks the film the guide pin separates the friction hold between pull bar andrack against spring tension so that the lever or slide can complete the remainder of its movement without affecting the film movement any furhter. The design is claimed to be simple, effective and reliable.
Patent DE-2340949-A1 (DE)
Title: Continuous sugar silo discharge system - using tubular drag-link conveyor along wedge-like discharge slot of elongated silo
Inventor: BUEHLER EUGEN
IPC: B65G65/42
Filed: 1973-08-13
Abstract: A hygroscopic free-running material, such as sugar mixed with milk powder in chocolate mfr. is discharged from a silo with a wedge-like discharge opening and transported directly to the next processing station (a sugar mill in a chocolate factory) by an endless tubular drag-link conveyor. The intake tube extends over the full length of the silo and is joined to it by a lateral funnel which terminates low enough to partly fill the tubular section. This allows the plant to be restarted, even after a prolonged stoppage, without having to run it empty. Starting at full load require little power.

Title: Seven-day alarm clock - has cam operated contacts and visual indication of days without alarm by levers
Inventor: STEMME WALTER
IPC: G04C21/20
Filed: 1973-08-24
Abstract: An alarm clock can be set to sound the alarm a full week ahead on a certain time each day, or not at all on certain days, and the programme can be altered at any time if desired. The clockwork drives a drum with seven cams, one for each day and offset axially. Each activates for one day the contacts which close the circuit for a conventional alarm timing unit. The days on which no alarm is desired are selected by depressing the appropriate lever which breaks a contact. The lever ends give a visual indication of the alarm days.

Title: Reservoir with level monitor for dual circuit brakes
Inventor: KAUFMANN HEINZ
IPC: G01F23/56
Filed: 1973-09-12
Abstract: The reservoir housing is made from upper and lower plastic mouldings welded together on a joining middle flange. The upper moulding has level monitors moulded to it with each monitor having an integral float which operates a warning contact when the fluid level drops to a min. value. The plastic mouldings require no further seals between the two circuits and are filled by a common port. One monitor may serve for both systems with a balancing duct so that both levels drop to the min. value before the warning is operated, with further level dropping inhibited in the good circuit.

Title: Contactless textile spindle speed measurement - by oscillator circuit coil facing recess producing oscillations at two amplitude levels
Inventor: SALM DIETER
IPC: G01P3/48
Filed: 1973-11-02
Abstract: The speed of spindles of textile machinery can be measured without any mechanical contact if the spindles have a nonhomogeneity such as a keyway or a recess on the periphery. A coil which faces it is part of an oscillator circuit supplied via a rectifier. The oscillator output is amplified and converted by a Schmitt trigger into square pulses. These are measured by a frequency meter and indicate the spindle speed. This method is less affected by interferences than permanent magnet systems. It can be used to indicate any speed, including zero.

Title: Two or three dimensional copying arrgmt. for machine tools - esp milling machines to machine curved workpieces
Inventor: LEEB FELIX
IPC: B23Q35/04
Filed: 1974-06-20
Abstract: The copying arrangement is especially used for the machining of deep drawing dies for sheet metal parts, and consists of a probe (4) and of a mill (7) with dimensions which are proportional to those of the probe and corresponding transmission between the movement of probe relative to pattern and milling cutter relative to workpiece along one axis. The cut of the milling tool at each point deviates over a known distance from the corresponding point where the probe touches the model. The probe is smaller than the milling tool by this known amount in length as well as in radius. The radius between the flat end face (8) of the mill and its circumference is also equal to this known distance.
