Patent DE-2820190-A1 (DE)
Title: Double skinned fire-proof door - has fire resistant filling and fusible water containing vessels acting at elevated temp.
IPC: E06B5/16
Filed: 1978-05-09
Abstract: The fireproof door is fitted with a device which in case of fire produces a cooling effect and herby achieves the required hours of fire resistance. The door leaf (4) is fitted in frame (1) and has skins (5, 6) at a distance from each other with gap closed by circumferential strip (7). The gap is filled with a fire-resistant material (9) which usually consists of a fluid-absorbent fluid. On the upper and lower part of the gap fluid filled containers (10) are fitted. They are designed in such a way that at a certain temp. they open up and discharge their fluid content into the gap where it is absorbed by the porous fillint (9) and subsequently evaporates producing a cooling effect which extends the time of fire resistance of the door.

Title: Variometer for radio-controlled model aircraft - has pressure chamber coupled to opto-electronic transducer providing signalling or servo output
Inventor: WIEBALCK RAINAR
IPC: G01P3/62
Filed: 1978-05-30
Abstract: The variometer comprises a small drum-like pressure chamber (3) across the top of which is stretched a membrane (5). The skin has a light barrier (8) which interrupts the light output of a LED (10) aligned with which is a photo-transistor (11). The transistor is coupled to a comparator (61) whose output drives a second comparator (70) whose output is connected to a flash unit (73). This triggers a gas discharge tube or alternatively an aircraft control surface servo-mechanism. The flash tube signals the ground operator. The control valve (V1) in the air inlet to the pressure chamber is actuated by a mechanical coupling ganged to an on-off switch (S1) in the 4-volt supply line.

Title: Shower head with non-drip action - has resilient closing member only released by pressure of water flow
Inventor: GROHE KLAUS
IPC: B05B1/30
Filed: 1979-03-27
Abstract: The distributor pipe of the shower heads has a closed end base and several radial openings set in front of the base in the flow direction and each closed by an expanding resilient tubular sleeve or other closing element which can be radially lifted off by the flow pressure. When the water supply is cut off no more water can flow from the pipe into the shower head so that there is no dripping and water does not remain in the head which could cause chalk to form. The sleeve can be surrounded by a tubular wall which with the sleeve forms an annular gap at least twice as thick as the sleeve and connected to the outside air.

Title: Latch for pushbutton movable between two end positions - uses heart shaped cam with additional step surface, and resetting spring for tracing pin
Inventor: SCHINKE HANS-JOACHIM
IPC: H01H13/56
Filed: 1979-07-03
Abstract: The push-button is linearly movable in a guide plate, in which it is prestressed by an energy storing spring. The latch has a heart-shaped control cam with a channeled guide path with shouldered bottom surface. In the cam is guided a mechanically prestressed tracing pin with a mechanical link, enabling short lifting from the cam bottom surface against the prestress. Adjacent to the latching point and the start of the retracting section of the guide path is provided an additional stepped surface on the upper edges of both wings of the cam. The level of the surface is in agreement with the height of the pin (2) lifting via the link (3). This level is higher as all adjacent sections of the bottom surface of the guide path. The energy storing spring (29) exercises a resetting force on the tracing pin. This force is orthogonal to symmetry plane of the cam.

This frame has four upper and lower sides held together by screws and holds the plates (1) firmly in position along the four edges. Frame shaped cover plates (8,9) also hold the sheets in a tensioned position, and when the whole arrangement has been adjusted, the cover plate, screws (11) enable the retaining pins (3) to be dispensed with. The perforations in the sheets align exactly with one another.
Patent DE-2930431-A1 (DE)
Inventor: HAAR HANS-PETER DR RER NAT
IPC: G01N21/25
Filed: 1979-07-26
Abstract: In a polychromatic photometer a sample wheel containing angularly spaced sample compartments and a filter wheel containing angularly spaced filters are rotated by a common drive arrangement so that the sample compartments and filters are in turn rotated through and aligned with the optical path of a photometric measuring device. The number of sample compartments is different from the number of filters. The number of sample compartments and the number of filters are not evenly divisible by a common integer. The ratio of the angular velocity of the sample wheel to the angular velocity of the filter wheel is substantially equal to the ratio of the number of filters to the number of sample compartments.

Patent DE-2942891-A1 (DE)
Title: Automatic revolution rate limit monitor for prime movers - has fail-safe circuit for checking pulse integral counter resetting
Inventor: SCHALLOPP BERNHARD DIPL PHYS
IPC: G01P3/488
Filed: 1979-10-24
Abstract: The method of automatically monitoring a revolution rate limit for many types of machine, esp. prime movers, involves a digital pulse transducer and a device measuring the time between successive rotation pulses. The circuit involved, is proof against component failure giving very accurate and reliable monitoring. All conceivable component failures tending to block the limit value signal are automatically detected and signalled or cause the unit to assume a safe condition. This is achieved by converting short circuits into open circuits using breakers and open circuits into disconnect signals using quiescent current signals. The absence of count pulses or the incorrect condition of a counter also cause disconnect signals. An alarm signal is generated if the counter is not reset to zero by the time measurement. The alarm is suppressed if the fault condition occurs simultaneously in redundant channels under critical conditions.

Title: Carcass cutting station - with angular and height adjustment for ergonomically right position
Inventor: SCHWEISFURTH KARL LUDWIG
IPC: A22B7/00
Filed: 1980-03-21
Abstract: Carcasses of animals, esp. quarters of beef carcasses, are taken to stations for the detachment of cuts from the bones by an overhead monorail system. Adjustable support structures (as regards inclination) and adjustable monorail sections (as regards height) bring the carcass to the ergonometrically right position for the execution of the cuts, which are kept stretched by gravity. The cut strips drop on a conveyor and the bones are thrown in a box. This speeds up the dissection and reduces manual labour to a minimum.

Title: Aq. polymer dispersion automatically controlled - by metering constituents as function of weight of droplets obtd. by regular sampling
Inventor: SCHMIDT ADOLF DR
IPC: C08F2/24
Filed: 1980-03-27
Abstract: A method of producing an aq. polymer dispersion in the presence of monomers, emulsifiers and radical formers uses re-adjustment of the dose of emulsifier soln, possibly also monomer and aq. initiator soln. During polymerisation the reaction mixt. (latex) is periodically sampled and fed, at constant temp. in a water vapour-satd. protective gas atmos., over a droplet-forming surface; after a predetermined number (N) of droplets has dripped from this surface, the material is collected and automatically weighed and from this reading the quantity of emulsifier and/or monomer or initiator soln. is readjusted. Pref. the weight (G) is compared with a set-point value and the quantity of soln. which is added is sufficient to keep the difference between actual and set-point values as small as possible. The pref. set-point is the value of (G) for the final dispersion. The pref. protective gas is nitrogen or a noble gas, opt. contg. vapours of those components which are present in liq. form in the polymer dispersion. The relationships between latex particle dia., emulsifier content, surface tension and degree of saturation are used for controlling the prod. Particle sizes in the range 30-1000 nm (pref. 80-600) are made.
