Title: Safety switch for tumble dryer service covers - prevents removal of lint filter or condensate container from running machine
Inventor: OTT HELMUT
IPC: D06F58/24
Filed: 1979-07-07
Abstract: Tumble dryer has a condenser, a container to catch the condensate, and a lint filter arranged alongside each other beneath the drum, with a covered access separate from the main loading door. Behind the condensate container is a safety switch which closes, permitting the machine to operate, only when the condensate container is pushed fully home. The cover flap of the lint filter, which is alongside the container, has a catch which engages the front of the container when the flap is locked, and can only be released by partial withdrawal of the container thereby opening the safety switch and stopping the machine. Dual protection is thus obtained from a single safety switch.

Title: Metering and transfer mechanism for liq. metal - with powder cylinder on two-armed lever carrying scoop
Inventor: BOLLAND OTTO DIPL ING
IPC: B22D39/02

A compressed air cylinder is attached to the other (shorter) arm of the lever to counterbalance the wt. of lever, rod, scoop and scoop contents. The lever can be swivelled around the top of an upright to bring the scoop above the point of its desired discharge. This is a simple device which requires little power or compressed air.
Patent DE-3000945-A1 (DE)
Title: Plastics stencil for machine readable filling in of lotto forms - has corresp. number fields with weakened edges so that selected ones can be pushed out to leave punched holes in right places
Inventor: SAUER ECKHARD
IPC: A63F3/06
Filed: 1980-01-10
Abstract: The plastics card is printed with the same numbers as the original Lotto sheet and is of the same size so that it covers it exactly. The boundaries of the number fields are pre-stamped such that they remain in position despite torsion and bending yet are readily removed by, e.g. the tip of a ball-point pen. The resulting holes allow a pen to cross the selected numbers accurately without transgressing into neighbouring number fields. The stencil thus enables the favoured numbers to be filled in quickly each week and serves as a storage device and aide- memoire for the same. The colouring chosen can have a greater contrast than the yellow dictated by the demands of machine readability. At last, blind people can join in.

Title: Self supporting flexible cable duct - has interlocked wall windings with integral profiled spacer band
Inventor: KLEIN ERNST
IPC: F16L3/015
Filed: 1980-02-15
Abstract: The cable duct with flexibility for moving machinery has a spiral wound wall with interlocking profiles. A reinforcing insert band (32) acts as a spacer to hole one side of the duct without any axial extension while the other side has axial freedom to enable the duct to bend only in one direction. The rigid side is located on the bottom of the horizontal duct, and ensures that it lies horizontal over an unsupported reach. The duct can flex sideways and even upwards without affecting the support. The spacer band has a periodically varying width with the period representing the circumference of the duct.

Title: Heat-resistant nickel-molybdenum alloy prodn. - by heat-treating alloy contg. nickel, molybdenum, iron, cobalt, chromium and manganese
Inventor: TANK EGGERT
IPC: C22F1/10
Filed: 1980-04-05
Abstract: Heat resistant Ni-Mo alloy is produced by heat treating a conventional alloy, of compsn. (by wt.) 74-65% Ni, 26-30% Mo, max. 2% Fe, max. 1% Co, max. 1% Cr and max. 1% Mn, at 650-750 (pref. 690-710) deg.C for 1-96 (pref. 48-72) hrs. The alloy is esp. useful as a self-lubricating material for mfr. or coating of drive components, operating at 400-600 deg.C and a sliding friction pressure of 5-20N/sq.mm., as well as rotating shafts, bearings and seals, in contact with the same alloy, not work sheets (e.g. x38CrMoV51 or x40CrMoV51), high speed steels (e.g. DIN 1.3207, 1.3243 or 1.3342) and martensitic chromium steels (e.g. DIN 1.4112 or 1.4122). Heat treatment of the alloy (NiMo28) gives a hardness of up to 41HRC which is maintained at up to 600 deg.C. At above about 400 deg.C and under friction conditions, the alloy surface forms a soft oxide contg. Ni oxide and Mo oxide, which is self-regenerating, adherent and resistant to hot oxidising gases. The alloy can be shaped by casting, machining or working since it is relatively soft before heat treatment and heat treatment can be carried out in air followed by cooling in air.

Title: Purified air feed esp. into automobile - heats air before filter to improve sorption and catalytic effects
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/00
Filed: 1980-05-16
Abstract: A method of purifying air to be fed into a protected working zone or automobile cabin utilizes a filter consisting of a permeable support on/in which chemical absorption materials and/or catalysts are laid. The incoming air is entirely or partly heated before it reaches the filters. When the appts. is in use, the normal fresh air inlet ducts of an automobile are closed and the ventilator fan is converted for use as a pure circulating fan recycling the entire air content of the vehicle. In addn., a separate ventilator fan draws in air and expels it at above-atmospheric pressure into the circuit via the chemical absorption filter. A corresponding quantity of air escapes from the circuit to atmosphere. In particular for automobiles in traffic jams or smog conditions as a substitute for conventional ventilation. By heating the air before it reaches the chemical absorption filter, moisture in the air is prevented from precipitating. Precipitation of moisture has a very adverse effect upon the effect of chemical absorption agents and catalysts. Thus the efficiency of the plant is greatly improved.
