Title: Transparent end cap for optical cable - has strain relief elements and permits optical testing through organic glass
Inventor: GOLDMANN HORST ING GRAD
IPC: G02B6/44
Filed: 1976-08-20
Abstract: A capping for an optical cable consists of an optical transmission core with strain relief elements clad in plastic. The cap is comprised of one or more glass-clear plastics. It may take the form of a cup shaped (2) with depressions (21) in its inner wall, made of a glass-clear plastic, the space between the cable and the cap being filled with a glass-clear cast-in plastic filling. The cap gives protection from the ingress of moisture, and allows traction to be exerted on the cable, and permits optical testing of the cable through the transparent plastic.

Title: Attachment for removing snow from ski boots - is formed with serrated edge and is screwed to ski behind boot
Inventor: HASSE DIETRICH
IPC: A63C5/06
Filed: 1977-01-20
Abstract: To fix skis to the ski-boots it is necessary to remove any snow which may have adhered to the soles. The ski-stock is often used for this purpose but its single point is not very effective. The invention proposes to use an angle section (3) with a serrated edge (2) screwed to the ski (1) behind the heel fixing bracket (4). Other applications of the same basic idea include fixing the angle section (3) to the ski in front of the toe fixing bracket. Or the serrated edge may be attached to the shank of the ski stock or the end of the stock can be made into a flat blade with a serrated edge.

Title: Piercer layout for holes in undulating drainage pipes - has cam rails ensuring positive retraction of punching tools
Inventor: OLTMANNS HEINRICH
IPC: B26F1/00
Filed: 1977-03-01
Abstract: An installation for producing holes in the troughs of the waves of undulating pipes, esp. for drainage purposes, is described in the parent patent. Installation has tool holders for the punching tools transported by endless chains. These move synchronously with the forward feed of the pipe, and the complementary profile of the tool holder locks on to the wave-form surface of the pipe. The punches move in the tool holdes under the action of cams and compression springs. In the Addn. the punches have a small plate projecting from the tool holder which acts as a cam follower for a stationary re-set cam. The punches work with stationary, freely rotating rollers, so that as they pass the piercing station, their free ends contact the rollers which depress them. The re-set cams are formed by rails with falling and rising flanks in front of and behind teh punch operating rollers. The machine works reliably and constant supervision is unnecessary.

Title: Poly:hydroxylated cpds. prepn. from formaldehyde - by condensing in presence of specified metallic cpd. and an alcohol
Inventor: WAGNER KUNO DR
IPC: C08G18/32
Filed: 1977-05-11
Abstract: Polyhydroxylated cpds. of low mol. wt. possibly with hydroxyaldehydes and hydroxyketones, are prepd. by the condensation of formaldehyde hydrate in the presence of (I) 0.01-10 wt.% metallic cpd. catalysts and (II) 0-10 wt.% co-catalysts based on cpds. transformable into enediol. This condensation is carried out at 10-150 degrees C in the presence of (II). (I) is a sol. or insol. cpd. of the 1st to 8th sub-groups or 2nd to 4th principal groups of the periodic classification, possibly fixed to high molecular wt. supports. (II) is, at a level of >10 wt.% wrt HCHO, of >=1 mono- or polyalcohols of low mol. wt. and/or polyhydroxylated cpds. of high mol. wt. The reaction is terminated at a residual HCHO level of 0-10 wt.% by deactivation of the catalyst, the catalyst is eliminated and, if desired, the aldehyde and ketonic groups in the prod. are reduced to hydroxy gps. The polyhydroxylated cpds. can be used e.g. as cross-linkers in the prepn. of polyurethane resins, chain elongators, swelling agents, catalysts, to prepare nonionic surfactants, as humectants, anti-freezes, microorganism nutritive media, etc. The method gives 30-75 wt.% polyalcohols in the mixt., without decomposition products. Hydrogenation or redn. of the mixt. is simple and economical, because of the relatively low carbonyl gp. concn. High reproducibility of distribution can be obtd., e.g. mixts. contg. more than 80 wt.% >4C cpds. can be prepd. Colourless prods. are obtd. which can be hydrogenated directly.

Title: Laminated plastics corrugated tube - used e.g. for conveying warm air to bubble baths, has heat-insulating ply of wound PVC foam strip
Inventor: EICHELBERGER LEO ING GRAD
IPC: F16L11/115
Filed: 1977-05-17
Abstract: Multi-ply, spiral-reinforced, plastics corrugated hose has a mantle of overlapping strips extending codirectional with the reinforcement and forming corrugations, and an outer hose. The plies lie spaced between the turns of the reinforcement and the outer hose is formed by a strip lying overlappingly upon the crests of the corrugations where it contacts the strip under it. The plies are parallel between turns of the reinforcement. The improvement is that the strip forming the outer hose is a foam material. This markedly improved heat-insulating characteristics of the article, thereby widening its range of uses. Thus it is possible to use it for supplying warm air to so-called aerated or bubble baths without appreciable cooling of the air.

Title: Ethanol prodn. from methanol, carbon mon:oxide and hydrogen - using nickel catalyst with iodine as promoter, giving higher yield than cobalt catalyst
Inventor: FREMERY MAX DIPL CHEM DR
IPC: C07C29/32
Filed: 1977-06-15
Abstract: The reaction is carried out at 200-1000 bar and 150-250 degrees C, followed by catalytic hydrogenation at 100-300 bar and 150-250 degrees C. Reaction is pref. carried out for 10-60 min in the presence of a supported catalyst contg. >30% Ni. The I2 is removed from the reaction prod. before hydrogenation (to prevent impairment of the hydrogenation activity of the catalyst). Ni salts (e.g. Ni acetate), activated Ni (e.g. Raney Ni) and esp. supported catalyst (e.g. Ni on Al2O3 or Al2O3-SiO2) can be used.

Title: Archery bow with curved cross section - has variable bending resistance which is reduced during final stretching stage to aid aiming
Inventor: NENTWIG CHRISTIAN ING GRAD
IPC: F41B5/00
Filed: 1977-08-27
Abstract: The archery bow cross section varies to ensure that its resistance moment is varied on stretching the string. The bow cross section has circular arc shape, and this shape may be used over the whole length of the bow. Alternatively the cross section mid part may be straight and its ends may be turned inwards to form approximately curved cross section. Most of the energy is stored on stretching over the first third of the whole stretching distance. In the last stretching stage the additional force needed is very small.

Title: Remote heat transfer leak monitoring system - uses temp. dependent resistance network as measuring cells, connected to comparison circuit
Inventor: CHABORSKI HOIKO DIPL ING
IPC: H04Q9/00
Filed: 1978-01-03
Abstract: The leak monitoring system for a remote heat transfer system uses a large number of measuring cells acting as sensors and fed with a constant current. From these cells is obtained a series of signals corresponding to the temperature levels which are tested and stored by a control circuit. This circuit compares the actual values obtained with a set of nominal values so that a fault signal can be obtained and used. The measuring cells can be temperature dependent resistances in a series/parallel arrangement connected by analogue switching system with a series of monostable vibrators. The fall in voltage is measured by a differential amplifier and the signals fed to the central control unit.

Title: Mechanical gravity and acceleration measuring device - uses eccentrically weighted planet wheels with motor-driven pinion
Inventor: HEEKE FRANZ-JOSEF
IPC: G01V7/00
Filed: 1978-05-19
Abstract: The gravity meter/accelerometer consists of two main wheels (4.01) inside which rotate planet gears (4.02). Each planet wheel has an eccentrically positioned weight whose centre of gravity is placed so that the overall centre of gravity (4.04) is outside the axis of rotation of the main wheels. The planet gears are driven via a central pinion (4.05) so that the overall centre of gravity remains in a predetermined position even when the main wheels rotate and accelerate. The pinion is driven by an electric motor connected by a flange to a shaft. The motor housing rotates with the main wheels, current being supplied via slip-rings. The position of total centre of gravity is sensed (4.10) and controlled by varying the motor current. The pinion is driven accordingly so that the overall centre of gravity remains in the predetermined position.
