Patent DE-2612359-A1 (DE)
Title: Electrophotographic material based on photoconductive polymer - contains photoconductive plasticiser, giving higher sensitivity
Inventor: HARTMANN HEINZ
IPC: C08K5/00
Filed: 1976-03-24
Abstract: Electrophotographic recording material with an organic polymer (I) as photoconductor contains 5-35 wt.% plasticiser (II) with photoconducting properties, w.r.t. (I). Pref. (I) is polyvinylcarbazole (Ia) and (II) is a cpd. with a system of 2-4 condensed aromatic or heterocyclic rings and cyclic ether gp(s)., pref. linked to the condensed ring system by an ester by an ester or ether gp. Properties and esp. the sensitivity are much better than with conventional plasticisers. (II) has the formula R-CH2-R1, R-CH2-O-R-1, R-CH2-O-CO-R1 or R-CO-OR1(in which R is the condensed ring system and R1 the cyclic ether gp.). E.g. the use of 2-dibenzofuran-2-yl-methoxymethyl-tetrahydrofuran instead of a non-photoconductive plasticiser in a material based on (Ia) increased the dark decay time and reduced the exposure time needed over a wide range of wavelengths, with little effect on the physical properties.
Patent DE-2613129-A1 (DE)
Title: High speed ventilator head for ship - has flap angled at acute angle of incidence for min. airflow deflection
Inventor: WITT HENRIK TORSTEN
IPC: B63J2/10
Filed: 1976-03-27
Abstract: The venting ducts for the ship are capped with high speed heads which have angled covers so that the vertically moving airstream is deflected by only a shallow angle of less than 45 deg. as opposed to 90 deg. in conventional ventilators. The flap can be hinged or can be a vertically moving cone (16), both operated by servo motors or rams. Splash guards inside the ventilator duct prevent ingress of water. The high speed ventilator reduces the number of ventilator outlets on the deck. The outgoing airflow is fast enough to blow out any spray, and with the flap hinged at the bows end of the duct, the duct is protected from waves. The system is suitable for venting large volume vessel such as roll-on, roll-off ships in which the lorries can generate large amounts of fumes.
Patent DE-2625962-A1 (DE)
Title: Antiskid protection valve for railway vehicle brakes - ensures rapid brake cylinder pressurisation and release on skid signal
Inventor: STROHMER ALFRED DIPL ING
IPC: B60T8/48
Filed: 1976-06-10
Abstract: The antiskid protection valve is used in railway vehicles for pressurising the brakes when a sensor indicates a skiding signal. When thi signal vanishes then the brakes are released. The valve acts rapidly for pressurising the brake cylinder of the skiding wheel. The brake cylinder pressure is monitored and the pressure is rapidly released after the skidding signal vanishes. The valve chamber (13) connected to brake cylinder is connected by releasing valve (18) to the atmosphere. A pressure reducer valve (19) is connected to compressed air source. The releasing valve (18) is actuated against a spring force towards closing position. The pressure reducer valve is held closed by a spring force and brake cylinder pressure against the compressed air pressure. The sensor actuates control valve (15) for blocking the compressed air source to the releasing valve and pressure reducer valve.

On the markings are pref. mounted electrical contacts with a current supply wire (13), and an in candescent bulb (5, 6) so that the latter lights up in certain positions of the joint. The appts. thus always adjusts the picture to the perfectly correct position.

Title: Liq. flow monitor handling irregular flow - employs sensor which responds to head of liq. and generates alarm signal
Inventor: THEDIECK REINER DIPL PHYS
IPC: A61B5/20
Filed: 1976-08-20

Title: Acoustic velocity measurement of slow moving media - using periodically interchanged piezo transducers operating at HF
Inventor: KROEBEL WERNER PROF DR
IPC: G01P5/24
Filed: 1977-01-03
Abstract: The measurement of the velocity of movement of a medium is based on measurement of sound waves transmitted between two identical single-crystal quartz transducers immersed in the medium. The electrical connections to the transducers have similar phase characteristics up to gigahertz frequencies and are periodically reversed at a rapid rate. A transducer head has a quartz piezo-electric transducer which acts as a piston generator mounted on a shoulder in a ball-shaped metal head. A hollow chamber inhibits back radiation. Electrodes are provided for the electrical connections to the piezo transducer which is fed through a tubulr hole. A thick, piezo-inactive window permits acoustic coupling to the medium. O-rings seal the transducer against ingress of sea water and permit operation at great depths.

Title: Note-book for duplicate recording of data - has type-written lines alternating with lines in code for reading by computer
Inventor: HILBERG WOLFGANG DR ING
IPC: G06K19/10
Filed: 1977-03-05
Abstract: A loose-leaf notebook is used to record information in two ways simultaneously. The information is typed in widely spaced lines so that it can be read directly. A special typewriter repeats the information in lines of symbols between the lines in normal script. The symbols are in the form of groups of vertical lines of different thicknesses embossed into the paper. These symbols can be "read" by a machine which slides a stylus over the symbols. In order to ensure that the stylus passes over the symbols a template with transverse slots corresponding to the lines of the symbols is placed over the page as it is being "read" by the machine.

Title: Prefabricated heat exchanger cluster for cracking plant - has tubes in plates fitted into chamber with flow medium deflector
Inventor: ECKBAUER ROBERT ING GRAD
IPC: F28F9/22
Filed: 1977-03-25
Abstract: The prefabricated heat exchanger pipe cluster is used for guiding a first flowing heat exchange medium. The pipes are held in vertical holding plates and horizontal pipes form vertical rows. The pipes in adjacent rows are staggered.

Title: Acceleration of moisture-curing rate of silane-grafted polyolefin(s) - used as cable and wire insulation
Inventor: EILHARDT BERND
IPC: C08L43/04
Filed: 1978-02-24
Abstract: Moisture absorption and cross-6inking rate of thermoplastics e.g. olefin (co)polymers, grafted with a silane or silane cpd., are increased by exposure to a mixt. of water and a liq. carrier with better solubility in the thermoplastic. Used in cable and wire insulation, esp. for thicker layers as required for high-voltage high-current cables, and for jacketing of pipes, etc. Time required for cross-6inking is substantially reduced and mechanical strength increased.

Title: Cement compatible mineral fibre mfr. - with low alkaline earth content using power station slag
Inventor: IHLEFELD KARL-HELMUT
IPC: C03C13/06
Filed: 1978-03-06
Abstract: Cement compatible mineral fibres are made from raw materials based on alumina like substances, in which the raw materials contain =15% alkaline earth, esp. =10% CaO. The material forms a pozzolan on wetting and fibre formation, which can be transformed into calcium aluminate hydrate when combined with Portland cement and/or lime. A fibre thickener may be produced which is at least double the reaction depth of pozzolanic material, in the surface of the fibre, following the formation of the calcium aluminate hydrate. The glass fibres have a higher softening pt. than those used in prior art (950 degrees C cf. 800 degrees C) since the glass contains a small amt. of alkaline earth oxides. Reduced alkali reaction occurs with Portland cement.
