Title: Loading equipment for letters - has control operating circulating drive according to signal from sensor in stacking mechanism region
Inventor: BURKHARDT GISBERT DR
IPC: B65H33/18
Filed: 1977-05-28
Abstract: The loading equipment is for tough-shaped containers holding letter or similar flat missives. The latter are fed in sequentially to form stacks. The container is loaded from each stack sequentially. The letters are conveyed shortl side on onto a receiving surface of a stacking arrangement. Supports are fitted to a circulating drive and spaced to correspond to the length of the proposed stacks. A control generates the drive in dependence upon a signal deriving from a sensor installed in the region of the stacking mechanism. The supports are thereby moved along the receiving surface according to the growth of the stack.

Title: Exploration system for cross-steering and stacking seismic data - using sawtooth traverse of shot points centrally spaced between pair of linear detector spreads
Inventor: LAWYER LEON C
IPC: G01V1/00
Filed: 1977-05-27
Abstract: In a real seismic exploration, seismic impulses are generated successively at locations spaced along a centrally located, asymmetric sawtooth shot-point line which regularly crosses a median line coincident with the line of survey. Seismic waves resulting from each impulse are detected at at least a pair of detector spreads each parallel to the median line. Preferably the detected signals are summed on a cross-steered basis, such that the resulting traces associated with crossed sets of centrepoints normal to the survey line provide directional ("dip") information to better indicate a real subsurface structure. Additionally, the detected signal can be stacked on a common depth point bases (CDPS).

Title: Safety cut=out for mechanically operated door - has spring loaded roller detecting cable tension change, operating microswitch
Inventor: JAEGER FELIX
IPC: E05F15/00
Filed: 1977-06-08
Abstract: The safety cut-out for a mechanically operated door lifted up for the open position, incorporates a spring loaded roller bearing against the door operating cable. Deflection of the roller due to excessive or insufficient cable tension operates a micro-switch which opens the drive motor circuit. The cut-out responds to any form of malfunction. The cable (4) runs over a pair of rollers (8a) mounted on a fixed base (12). A third roller (8b) is spring loaded against the cable, and is deflected perpendicular to the cable by tension variation. A cam (17) mounted on the base (11) of the third roller (8b) operates a micro-switch (16) when the cable tension deviates from its normal working value.

Title: IR halogen lamp for grills and roasting appts. esp. for food - has a quartz lamp tube contg. oxides which absorb visible light and increase infrared emission
Inventor: MARQUARD KLAUS DIPL PHYS
IPC: H01K1/32
Filed: 1978-04-28
Abstract: The incandescent lamp uses a quartz tube which contains metal oxides and/or non-metal oxides. The oxides may be distributed uniformly through the entire cross-section of the tube, i.e. by adding the oxides to molten quartz used to make the tube. Alternatively, the oxides may be conc. in the outer zone of the tube by diffusion, none of these oxides being present at the bore surface of the tube. The oxides are pref. restricted to specific axial zones of the quartz tube, so that some radiation from the filament passes through plain quartz. In comparison with conventional infrared cooking lamps, the invention provides a simple method for reducing the amt. of visible light and converting the latter to infrared radiation, and also increases the yield of far infrareding the browning of food being cooked.
