Patent DE-2735118-A1 (DE)
Title: Propellant container for rockets - with oblique holes in bottom to impart spin to achieve greater altitude
Inventor: HALL RONALD GIBSON
IPC: F02K9/80
Filed: 1977-08-04
Abstract: A rocket for fireworks, signaling or life-savin purposes has a cylindrical container for the propellant, consisting of side walls and a base wall. One of the walls, for example the base, has through holes which are symmetrical to the centre line but describe an angle of 5-30 degrees (15-25 degrees) with it. The escaping propellant imparts a spin to the rocket so that it revolves around its axis. It thus reaches a greater height than a conventional rocket without spin.

Title: Hot gas or suspended solid particle flow monitor - uses differentiated temp. reading threshold values for safety control
Inventor: BUERMANN JOCHEM ING GRAD
IPC: F23N5/18
Filed: 1977-08-09
Abstract: Hot gas or suspended solid particle flow in pipes is monitored using temp. measurement by thermocouple. A differentiating unit produces a rate of chane of temp. signal. This signal is fed to amplifier units with positive and negative thresholds settings. If it drops below the negative threshold value a switch with a set delay is activated. Unless that activation is cancelled within the delay time by the signal rising, above the positive threshold value the switch operates.

Title: Ammonium hepta:molybdate prodn. - by extracting molybdenum tri:oxide concentrate with water and ammonia
Inventor: RONZIO RICHARD ANGELO
IPC: C01G39/00
Filed: 1978-01-11
Abstract: Prodn. of (NH4)6Mo7O24.4H2O (I) comprises first leaching a MoO3 concentrate in H2O at 70-95 degrees C (solids content 5-50%) for a time sufficient to extract at least part of the contaminating metal ions into the aq. phase. The leached concentrate is then sepd. from the aq. extract, and soluble molybdates are recovered from the latter. The leached concentrate is then leached with NH4OH soln. to extract NH4 molybdates, and the extract is sepd. from the insoluble residue and concd. in an evaporator to form a satd. soln. of NH4 molybdates. The satd. soln. is (partly) withdrawn and adjusted to a NH3:MoO3 molar ratio of 0.86-1.25:1, and is then cooled to ppte. crystals of (I). These are sepd. from the mother liquor, which is recycled for mixing with a fresh batch of ammoniacal extract entering the evaporator. (I) is used as an analytical reagent, for the prodn. of pigments and catalysts (e.g. for petroleum refining and coal treatment) and for the prodn. of metallic Mo. The process does not require a purified MoO3 starting material, air-roasted molybdenite concentrates are suitable.

Title: Automatic lathe with vibration free bar feed - uses small metal balls packed around bar-stock by hydraulic piston to eliminate unbalance
Inventor: DORMEHL ERICH
IPC: B23B13/08
Filed: 1978-05-03
Abstract: An automatic lathe has a headstock (2) with a central tube (5) through which the bar (8) is fed. Out-of-roundness in the bar creates out-of-balance forces at high rotational speeds and causes vibrations leading to inaccurate work. These out-of-balance forces are eliminated by filling the central tube with small metal balls (12) of the same specific gravity as the metal of the bar. The balls are packed around the bar by hydraulically actuated piston (10) which moves forward as athe bar is pulled through the chuck (4) after the parting off of each completed workpiece.

Title: Milk degassing cylinder - with two floats controlling two pick=ups for maintaining parabolic surface when supply fluctuates (NL 24.6.80)
Inventor: STAHLKOPF FRIEDRICH
IPC: B01D19/00
Filed: 1978-12-22
Abstract: A cylinder for degassing of a liquid prior to its volumetric flow measurement, esp. for raw milk, includes a first float of triangular section above a conical outlet cowl. It receives the milk through a tangential inlet on top so that the fluid revolves along the walls in a parabolic shape. Its vertical float rod controls a lower displacement pickup for control of a milk outflow throttle valve and the air vent valve. A second toroidal float above the first controls with its tube, which slides on the float rod, in addn. a second (upper) displacement pickup for control of the same valves. This ensures a faster response of the air vent and milk outlet rate to changes in the flow rate of the milk input. This prevents the paraboloid from collapsing so that the milk cannot entrap air.
Patent DE-2901149-A1 (DE)
Title: Exposure timing circuit for automatic photoflash camera - has potentiometer adjustment to set, or alter exposure time, with manual override
Inventor: NUMATA SABURO
IPC: G03B7/16
Filed: 1979-01-12
Abstract: The automatic photo flash control for a camera has the reflected light from the object monitored and the signal compared with a reference signal calculated from the exposure details and e.g. film speed. This generates a timing signal for the exposure speed. The control also provides a signal to indicate that the photoflash is ready. A manual override is provided to set a determined exposure speed, whose signal is fed into the comparator and operates the exposure irrespective of the lighting conditions. No additional circuitry is required, other than a potentiometer operated by the manual control. This provides a manual exposure speed, or modulates the automatic exposure speed.
Patent DE-2901205-A1 (DE)
Title: High efficiency blending extruder for plastics - screw feeds from hopper to revolving masticator producing high shear heat
Inventor: WITTROCK LUDWIG
IPC: B29C48/38
Filed: 1979-01-13
Abstract: Plastic powders/granulates are softened, blended and extruded, using heat produced by strongly turbulent flow in shear. The material is subjected to such high pressure as to compact it when soft and to enable it to be extruded at any desired speed. There is a double counter-rotating screw compression feeder in the hopper, this feeder raises the material temp. slightly before it enters the pressure chamber where the tool with its masticating lugs revolves at such speed as to produce both frictional and shock heat. Gases escape through the still porous mass to the hopper. The material emerges from the nozzle. The central tool can be moved axially if the material is to be injection moulded. The curve shows the pressure distribution along that part of the barrel. Highly efficient fusion and blending, hence large section and short barrel and therefore high output capacity.

Title: Control system for small vibratory agitators - having soft iron element inside coil fed by varying signal from wobble generator to ensure that part of time optimum agitation is achieved
Inventor: KLEIBRINK HORST
IPC: H02K33/02
Filed: 1979-05-17
Abstract: Rapidly moving agitator has a reciprocating electro-magnetic drive. This consists of a non-magnetic sealed housing surrounded by a coil. Inside the housing is a soft iron core mounted on a shaft with springs either side to enhance the reciprocating action. The coil receives an impulse from a wobble generator. This generator is adjusted periodically between a maximum and minimum value. The frequency of oscillation can be set on a potentiometer outside the unit. The spring are balanced so that the oscillation is uniform in both directions. Used in small sealed pressure vessels. Complicated control systems are uneconomic for small units while simple manual control can cause the agitator to be operated at a speed where the soft iron core has too much inertia to follow the oscillation in the coil.

Title: Purificn. of gases from pyrolysis of wastes - with reduced pollution from disposal of used absorbents
IPC: C10K1/32
Filed: 1979-11-07
Abstract: Process is claimed for the removal of harmful ducts and gases from the gases produced in the pyrolysis of waste matls., e.g. household refuse. After removal of pyrolysis coke, the gases are passed in intimate contact through a layer of physical or chemical absorbent, at a density of at least 1 kg/cubic m, and a temp. pref. above 250 deg.C. The absorbent may be in a fixed bed, or in a rotating ball mill, or in a fluidized bed. A filter aid such as powdered pumice may be used to lighten the absorbent layer. Suitable absorbents for acid substances are lime (added e.g. as milk of lime) and haematite. Pref. absorbents for basic substances are montmorillonite and bentonite. Relative to the usual process, in which absorbents are added to the pyrolysis reactor itself, the process requires less absorbent; and the separate streams of contaminated adsorbent and uncontaminated coke can be disposed of with less pollution of ground water than the usual mixed stream (coke being in larger amt.).
