Title: Wall rail clamp joint - rigid angular member and resilient tongue with threaded bore for clamping screws
Inventor: ZAHNER ALBERT
IPC: A47G25/06
Filed: 1973-06-27
Abstract: The support rail is fastened to the wall by holders which are fixed by screws engaging in dowels in the wall, with the rail suspended between the resilient tongue and rigid angular member, which are formed by the horizontal arm of the holder, so that the rail is supported by its side face of its upper rib against the opposite contact face of the tongue and by its lower edge of its inner rib on the support face of the angular member. Since the vertical arm of the angular member engages in the groove between the support rail and the inner rib and free end of the tongue engages in the groove formed by the outer rib and web of the rail, the latter is secured against lateral slipping. The clamping screws in the tongue are then tightened so that the tongue is bent to securely about the opposing faces of the outer rib and the angular member is drawn firmly against the inner rib.

Title: Molybdenum coating on extruder feed screws - for increased life of running edge when extruding plastics
Inventor: DETTWILER EUGEN
IPC: C23C4/08
Filed: 1974-01-22
Abstract: The running edges of worm feeder screws are coated with a layer of molbdenum, esp. in machines used for extruding plastics. The result is a substantial increase in feeder screw life. Worn screws can be built-up and costs reduced. The edges of new or worn screws are machined to below finished size and the surface roughened and sand-blasted. The flanks are then coated with a protective lacquer and the screws preheated to 40-60 degrees C. A molybden um coating is then applied using flame spraying with 99% Mo wire. A two-component bakelite sealing cpd. is then repeatedly applied to the Mo layer until the latter is satd. with the sealing cpd. The edges of the screw are then ground to the required dia. The Mo coating greatly extends the service life as compared with other methods of surface treatment, e.g. hard-chrome.

Title: Compost-making unit for waste - consists of sheet-clamp filled by conveyor above clamp
Inventor: KURNEY WERNER
IPC: A01C3/02
Filed: 1974-07-03
Abstract: The clamp is positioned above ventilation ducts and has a roofed-over feed conveyor and a transverse conveyor which is situated on a movable bridge and can also be roofed over. The clamp area is surrounded by a wall which is roughly one and a half times the height of the sheet clamp.

Title: Synthetic resin encapsulation for electric components - uses prehardening at lower temp., pressing onto component, and hardening at higher temp.
Inventor: BAAR HORST
IPC: H01B19/04
Filed: 1974-09-03
Abstract: The mixed synthetic resin coating, for encapsulation of electric components, consists of a mixture of resin and hardener mixed at a relatively low temperature and subjected to slow preliminary hardening process until it is no longer sticky. This mixture is then mechanically processed at normal temperatures over a longer period of time and formed into larger areas or strips which are pressed around the component and then hardened by heat treatment. If for example, the components are capacitors, they can be placed in-line and the prehardened resin strips pressed around them in bulk and the individual capacitors are then severed after hardening.

Title: Low-ripple peak rectifier has two charging circuits - which alternately charge capacitors with half wave input and switching through to output
Inventor: BAUERNFEIND KARL DIPL ING
IPC: G01R19/04
Filed: 1974-09-18
Abstract: The low-ripple peak rectifier has two or more charging circuits connected parallel to one another and each containing a capacitor (C1). The input a.c. signal is passed over a diode to this capacitor so that the capacitor is charged by one halfwave. The capacitor is discharge by a shorting switch (S1) before storing the next halfwave. After charging, the capacitor is switched by a second switch (S2) through to the rectifier's output (2) at the point in time when the a.c. input passes through zero. The capacitor remains switched through until the next time the a.c. passes through zero. The second charging circuit takes over the for next halfwave.

Title: Thickness measurement method - is for thickness of transparent layer on plane and transparent substrate for semiconductors
Inventor: LONGO HANS-EBERHARD
IPC: G01B11/06
Filed: 1974-10-21
Abstract: The method uses interference phenomena.

The angle of incidence of the second ray is varied until interference phenomena are the same in both cases. The required layer thickness is obtained from a specified equation relative refractive index, angles and spacings.
