Patent DE-2807247-A1 (DE)
Title: Probe for monitoring oxygen activity of molten materials - is made of sintered conducting refractory oxide core covered by solid electrolyte
Inventor: FISCHER WILHELM ANTON PROF DR
IPC: G01N27/411
Filed: 1978-02-21
Abstract: The probe consists of a comparison substance (a) of known oxygen activity, which is sintered to form a solid, metallically-conducting core(a) covered by a solid electrolyte (b) at least in the zone of the probe (a,b) which is immersed in the melt. Layer (b) is pref. 40-250, (50-150) mu m thick, with total porosity 20-45 esp (30)%. The probe is pref. made by mixing a refractory oxide powder (a1) with carbon or graphite powder and a binder (a2), followed by moulding or extruding to make a core which is sintered so the carbon reduces some oxide (a1) to form over 30 wt% metal. Oxide (a1) is pref. Cr2O3 or MoO2; and binder (a2) is pref. synthetic resin resol or novolak with hexamethylene. Layer (b) is pref. ZrO2 with CaO, MgO and/or Y2O3; ThO2 with Y2O3; 3Al2O3, ZSiO2(mullite); or Mg-Al-spinel. The probe is simple to mfr. but has a long working life, as it does not crack due to thermal shock.

Title: Pneumatic dialysis blood pump control system - includes comparators to monitor air pressure for changeover between diastolic and systolic pressures
Inventor: WALLNER FRANZ DIPL ING DR ING
IPC: A61M60/538
Filed: 1978-02-27
Abstract: The pneumatically driven blood pump has an automatic control circuit, which synchronises the diastolic to systolic and systolic to diastolic changeover points. It also controls the drive pressure of the pneumatic system at the input of the pump tube, using a constant temperature anemometer at this point. The changeover between diastolic and systolic takes place when a comparator establishes that the air flow falls below a determined very low value. This operates a mono flop in the control system, and the air flow is monitored by two further comparators, connected to an AND gate. A further mono flop determines a time delay. A sample - and - hold unit forms part of the control system.

Title: Sorting device for concrete reinforcement rods - has bins of different lengths to receive bars of corresponding size
Inventor: RUHL HEINZ
IPC: B65G47/78
Filed: 1978-05-26
Abstract: The off-cuts from steel rods for reinforcing concrete are of widely different lengths and much time is spent in sorting them by hand. To facilitate this sorting the rods (20) are rolled over a series of bins (11) of different lengths arranged side by side. One end of the bin assembly has a rail (14) extending over all the bins. The other end of the assembly has short pieces of rail (15-18) each piece at an increasing distance from the rail at the other end. The bars (20) roll over the rails until they reach a bin of sufficient length allow them to fall into it.
Patent DE-2823074-A1 (DE)
Title: Clearer for ice-breaker hull - has angled water jets in bows to keep floes from under hull
Inventor: WALTER WOLFGANG DIPL ING
IPC: B63B35/08
Filed: 1978-05-26
Abstract: The bows of the icebreaker are fitted with angled water jets (2) which force the broken floes outwards and away from under the hull where they could foul the screws and the rudders. The jets are angled to force the floes under the ice sheet to ensure a clear channel. The dispersal of the floes greatly reduces the drag of the hull through the ice so that the channel can be cleared at a faster rate.

Title: Continuous tube weld and stretch reducing mill - with specified arcs for reducing mill roll passes
Inventor: SAMARJANOV JURIJ V
IPC: B21B17/14
Filed: 1978-08-11
Abstract: A continuous weld and stretch reducing mill is assembled from alternating pairs of vertical and horizontal grooved rolls. The working surface of all rolls is formed by conjugate arcs of >=2 radii. >=1 Of the arcs has the same radius as that of the welding roll pass; the crowns of the arcs of the same radius lie in the same plane which passes through the longitudinal axis of the rolling mill. This results in a higher strength of the welded seam and in a higher precision of the tubes.

Title: Spreading device for running fabric - having deflection beam mounted diagonally across the path of the fabric
Inventor: MAYER ROLF DIPL ING
IPC: B65H23/32
Filed: 1978-08-18
Abstract: Appts. for straightening and spreading a sheet of running material, esp. woven fabric, to its fullest lateral extent over a region whose boundaries make a acute angle with the warp direction, operates by pulling it under tension over two deflection edges or rollers which are parallel to each other but set at different heights, and which make the desired angle with the direction of movement of the fabric, which is pref. 45-90 degrees. Appts. prepares the fabric for scanning by a photoelectric fault detector, which scans the fabric at an acute angle to the running direction to obviate responses due merely to the structure of the material.

Title: Telephone exchange call handling procedure - using storage to hold queue of incoming call information for routing in order by common control
Inventor: BARTHOLOMAE HENRIK ING GRAD
IPC: H04Q3/54
Filed: 1978-12-22
Abstract: The incoming calls are held in a FIFO (First in First Out) store until the control equipment is free to process them individually. The holding store works in synchronism with a control store which counts the incoming calls and initiates the routing procedures for each. Information from the subscribers (T, VP) is directed by the subscriber's uniselector (TS, PS) into the control equipment where it is queued in the queuing store (WF) and its presence is logged in the working store (SP). A cyclic store counter in the working store (SP) scans the lines to ascertain their state and co-ordinates the operation of the queue (WF) and working (SP) stores. The control also scans and can mark the cross points in the switch block, and the incoming and outgoing junction relay sets (Ue1, Ue2, Uem) of junction route (AL).

Title: Lure for line fishing - has internal battery and bulb for illuminating reflective feathers to simulate fish scales
Inventor: KNAUS BRUNO
IPC: A01K85/01
Filed: 1979-10-26
Abstract: The lure has a heavy underpart made of brass with an eye for fixing the hooks to which are also fixed feathery or additional luring parts made of a light reflecting material. The underpart is also provided with openings through which light can pass to illuminate the feathers, and for a light source, a filament bulb or flow lamp is fixed inside the body of the lure. The light source is supplied by a battery, which is fixed in the upper part (12) of the lure (1) and is so connected to the lamp that by the relative positioning of the two halves (12,2) of the lure, the current can be switched on. When the lure is below the water, any movement on the line will cause the light reflecting feathers (5) to alter the direction and strength of their reflections, thus simulating fish scales and luring cod, mackerel etc.
