Title: Pressure filtering of difficult media - with successive relaxations during press rise to delay time when max press is reached
Inventor: HAECKER KARL
IPC: B01D25/00
Filed: 1972-09-13
Abstract: A method of feeding material into a filter unit, esp. a filter press, operates with a gradual increase of the feed press. to a final press. which is then maintained right to the end of the filtering operation, while the rate of feed of material/unit time gradually and progressively decreases. The rate of increase (dP/dt) of feed press. (P)/unit time (t) is flattened-off at least once before the final press. (P max.) is reached, and then, after this flattening-off, is again increased. This is pref. achieved by reducing the power input, i.e. the product (P x Q) at least once during the increase of press., then again increasing this power input. Enables a given residual moisture content to be achieved in a shorter time, with a given max. permissable terminal press.

Title: VCO with phase control loop - has controllable capacitance diode for synchronised stabilisation to comparison frequency, using phase discriminator
Inventor: BAIER PETER
IPC: H03L7/12
Filed: 1973-09-03
Abstract: The reference voltage (stabilised frequency) is transposed to a lower frequency by a frequency conversion. The oscillator comprises a phase discriminator in the control loop, operating within +- 90 deg., and has a d.c. voltage output. A second phase discriminator is in parallel with the first one, and the oscillations are applied to it through a 90 deg. phase shifter. The output voltage of one discriminator operating symmetrically about a working point, e.g. voltage zero, is applied to the oscillator frequency controlling component, while the output of the other one, which passes through a voltage maximum in the same working range, is used as a criterion for the oscillator correct adjustment.

Title: Automatic temperature regulating device - for use during heat treatment of synthetic yarns
Inventor: KODAIRA NOBUHISA
IPC: H01H37/36
Filed: 1973-09-03
Abstract: Temp. regulating appts., whereby the temps. of the appts. is maintained at a constant by regulating a heat transfer medium vapour, includes a number of pressure sensing bellows which communicate via thin tubes with heating vessels. Each pressure sensing bellows has a lever for actuating a micro switch. Counter bellows are coupled to the pressure sensing bellows in an opposed relationship and each counter bellows communicates with one common constant pressure chamber. The pressure in the counter bellows is regualted as a whole by varying the pressure in the common constant pressure chamber. As the pressure in the counter bellows varies the temperature of the heating vessels as a whole is regulated.

Title: Adjustable louvres for motor vehicle radiator - are actuated by thermostat and solenoid actuated lever system for rapid warm-up
Inventor: GASPERS WILLI
IPC: B60K11/08
Filed: 1973-11-28
Abstract: The adjustable louvre in front of the motor vehicle radiator has horizontal strips which are actuated by a lever system. This lever system is connected to an actuating circuit which has a thermostat, a solenoid and a toggle lever. The toggle lever ensures that the louvre blades are not blown open by air stream or by fan sunction. The thermostat actuates a switch which in turn closes the energisation circuit to the solenoid. This solenoid actuates the toggle lever and the actuating linkage of the louvre blades. The thermostat opens the louvre only when the cooling water has reached a certain temperature. This system ensures that the engine warms up quickly.

Title: Relay spring contact set - has double-shank wound spring coupled to contact bracket and terminal stirrup for wiring connection
Inventor: DOST WILLIBALD
IPC: H01H1/24
Filed: 1974-01-24

Title: Flat-iron press requiring less physical effort - comprises balancing-spring tightened into position on moving carrier-arm
Inventor: HAMMER URS
IPC: D06F71/02
Filed: 1974-04-13
Abstract: The press comprises a pressing-arm, carrying the plate, and an operative arm, joined into a carrier-arm, which is rotatably mounted in the frame, which is connected, by way of a spring, to a rotary bow, mounted in the operative arm, so as to hold the carrier-arm in the upper rest-position, but exerts part of the ironing-pressure in the lower position. A balancing spring is provided, which, when the carrier-arm is moved, is tightened from the rest-position into the operational position by means of the bow. This arrangement reduces the effort required for moving the carrier-arm from the lower into the upper position.

Title: Medicaments in form of foils - prepd. by incorporating a drug in a soluble foil-forming material
Inventor: FUCHS PETER DR
IPC: A61K9/70
Filed: 1974-07-05
Abstract: Medicaments in the form of foils are prepd. by incorporating a pharmaceutical agent in a foil-forming material which is soluble in H2O and/or organic solvents. The prods. can be used internally or externally but are esp. useful for oral administration, e.g. of gestagens, oestrogens, tranquillisers, antidiabetics, sulphonamides, antibiotics, antitrichomonals and anti-inflammatories. Foils can be prepd. with uniform thickness and a uniform distribution of active ingredient, and losses of active ingredient during handling are minimised (cf. coated foils). Foils contg. more than one active ingredient (e.g. contraceptive gestogen/oestrogen prepns.) can be prepd. without these ingredients coming into contact with one another.

Title: Control valve for train pneumatic brakes - with three separate operating ranges to prevent brakes dragging when operating against leaks
Inventor: FALKE ERICH
IPC: B60T15/16
Filed: 1974-11-15

Title: Chemical metering pump - for water main driven by water motor with plunger stroke adjusted by pressure drop across by pass
Inventor: LANG HELMUT
IPC: B01F15/04
Filed: 1974-11-29
Abstract: A device to meter the addition of chemicals to a water main by means of a plunger pump, driven by a water motor with a cam mechanism, is fitted with a spring-loaded valve in a bypass to the water motor. A higher flow rate open this bypass valve and displaces thereby a fluid to move a piston with a rack-and-pinion which lengthens the plunger rod and increases the active stroke of the plunger in proportion to the higher flow rate. This allows a very sensitive adjustment of the depth of immersion of the additive pump plunger so that the proportionality is always maintained.

Title: Droplet separator - esp. for wet scrubbers for dust removal in underground mining machinery
Inventor: HOFFMANN DIETER
IPC: B01D50/00
Filed: 1975-01-16
Abstract: A droplet separator esp. for use in wet dust removal plants for treating air around in mining. The scrubbers are of the type in which the dust is deposited on droplets of liq. sprayed into a contact zone and the mixt. of dust and water is sepd. from the air flow by centrifugal force. The novelty lies in the provision of a swirl generator downstream of the contact-zone and a pipe downstream of the swirl generator, in which pipe a cylinder of fine mesh is co-axially located. An outflow connection is attached to the outer pipe to drain the annular space between the pipe and the mesh. The separator has a very high efficiency of sepn. Construction is very simple and enables compact easily transportable scrubbery to be made and min. maintenance is required.
