Title: Butane-1,4-diol and 2-methyl-propane-1,3-diol prepn. - from butan-1-al-4-yl acetate and 2-methyl-propan-1-al-3-yl acetate
Inventor: KUMMER RUDOLF DR
IPC: C07C31/20
Filed: 1975-02-19
Abstract: Process for prepn. of butane-1,4-diol, and 2-methylpropane-1,3-diol, and of their mono- and diacetates, takes place by (1) hydrogenating butan-1-al-4-yl acetate and 2-methyl-propan-1-al-3-yl acetate in the presence of (a) 2-8 (3-5) mol. MeOH (w.r.t. starting materials) and (b) catalytic concns. of an acid, (A), at 80-150 degrees C under 20-200 bar, using a hydrogenation catalyst, and (2) opt. converting the butan-1-ol-4-yl acetate and 2-methylpropan-1-ol-3-yl acetate, obtd. as hydrogenation prods., to the free diols, by hydrolysis, or to the diacetates, by esterification. Prods. are useful components for varnishes and polyurethanes and crosslinking agents for textile finishes. Presence of MeOH and acid (A) causes acetalisation of formyl gp. in starting materials. Acetalisation suppresses AcOH dissociation, as side-reaction, as observed in hydrogenation of the free aldehydes. Prod. yield in methyl acetal hydrogenation is increased to 89-98%, compared to diol yields of 30-40% in free aldehyde hydrogenation.

Title: VHF and UHF poly-directional transmit aerial - uses on sides of the support tower symmetrical central arranged and mirror-image positioned radiators
Inventor: VITO GIUSEPPE DE
IPC: H01Q21/26
Filed: 1975-03-06
Abstract: The transmit aerial for VHF/UHF frequencies consists of several radiator groups held in a mainly vertical position by a tower structure which has these radiator groups arranged symmetrical and central with regard to the structure sides. The radiator elements or groups in equal horizontal planes are fed in phase while the amplitude distribution in the vertical planes is varying. The radiator elements or groups which in the horizontal plane from a mirror image to each other are fed with a phase shift of 90 deg. between each other. The aerial thus seems divided into two parts each of which radiates the same fraction of the total energy. The radiator groups may be arranged in the form of a pine tree array or for polydirectional use.

Title: Water tube type hot water boiler - has flat U shaped waterways projecting in convective heating flue passage
Inventor: PACZKOWSKI KLAUS VON ING GRAD
IPC: F24H1/40
Filed: 1975-09-25
Abstract: Boiler has a combustion chamber with water tube sides receiving radiant heat and a second pass section with water tube sides heated by convection from the flue gases. Water enters through headers at the top of the secondary section, flows down the sides of this into base headers and from these through the sides of the radiant heating section. Flat rectangular channels bent through two right angles to form a U are connected at intervals to the tubes of the sides of the secondary section. The legs of the U are connected to the tubes above each other and the flat surfaces project into the flue passage. This provides a good heating surface whilst reducing the water side resistance.

Title: Spectro-photometric appts to detect synthetic gems - e.g. differentiation between natural, hydrothermal and "selsfondus" beryl
Inventor: LANDAIS EDMOND LOUIS ROBERT
IPC: G01N21/87
Filed: 1975-10-02
Abstract: In a spectrophotometric appts. for differentiating between natural and synthetic precious stones using a continuous-spectrum radiation source, a monochromator and a sample carrier, the monochromator has a first carrier plate to which interference filters can be fitted and moved perpendicularly to the beam of light so that they can be centered on the beam. A second carrier parallel to the first and further than the first from the light source carries a polariser which can be centerd on the beam axis and rotated. The sample carrier consists of a parallel-sides conventional cuvette of a material transparent w.r.t. the light source and contains a liq. with a high sensitivity refractive index approx. equal to that of the sample stone. At least one filter is transparent for light of characteristic wavelength for the sample stone, whose wavelength corresp. to a sharp narrow absorption band of the absorption spectrum for a molecule of different composition to that of the stone. A second filter is transparent for wavelength in the same spectrum showing no absorption, whilst the liq. in the cuvette is transparent w.r.t. a range of wavelengths of the spectrum wider than the range of wavelengths for the filters. An optical indicator is provided behind the sample carrier giving a signal proportional to the absorption value in the stone. The appts. is comparatively cheap and simple. Subjective optical assessments are replaced by graphical outputs from the analyser. The apts. is portable and can be used by unskilled personnel.

Title: Self actuating rotary spray for cleaning - has rotating nozzle directing jet of fluid onto work surface with fluid producing turning force for nozzle
Inventor: HART BERNARD EATON
IPC: B08B5/02
Filed: 1975-10-29
Abstract: The spray device has at least one nozzle which is connected to a pressure fluid producer and rotates around an axis of rotation offset in relation to its own axis and vertical to the surface to be cleaned. The axis of the rotating nozzle is hereby at such an angle to the axis of rotation that the fluid emitted produces a turning force which drives the nozzle. A mechanism driven by the rotating nozzle produces a flow of fluid from the medium surrounding the spray gun which exerts a force on the spray gun acting in the direction of the axis of rotation.

Patent DE-2615691-A1 (DE)
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/525
Filed: 1976-04-09
Abstract: The inverter arrangement comprises an inverter (2) controlled by a control device and an inverter transformer (4) with iron core. In such an inverter arrangement, there is a risk of saturation of the iron core of the inverter transformer (4) if the output voltage of the inverter (2) is not completely free of DC components. Saturation of the iron core of the inverter transformer (4) is to be prevented without requiring a special design of the transformer. For this purpose, a measuring device (5, 20, 18, 17a, 17b) for detecting and differentiating the amount of the magnetising current of the iron core of the inverter transformer (4) is provided. The control device (8, 9) of the inverter (2) is influenced in dependence on the differential quotient of the magnetising current, in such a manner that the voltage/time area present at the inverter transformer (4) in each case is instantaneously prematurely reduced in size. <IMAGE>
