Patent DE-2532733-A1 (DE)
Title: Sprung ski safety binding - has grip automatic release of heel as soon as unlocking point is passed
Inventor: RIEDEL TILO
IPC: A63C9/084
Filed: 1975-07-22
Abstract: The ski safety binding allows length adjustment or swivelling of at least one part of the heel gripping mechanism. A tipping movement of the heel grip mechanism in relation to the jaw releases the sole anchoring device upwards as soon as a predetermined point termed the unlocking point has been passed. The heel gripping mechanism has a spring release bringing it into an open position as soon as the unlocking point (P) has been passed. In addition there are locking hooks or pins to hold the heel grip mechanism closed during transportation of the skis. The locking device is automatically released by the release lever of the heel grip mechanism.
Patent DE-2533648-A1 (DE)
Title: Afterburner for engine exhaust gases - with ring injector for preheated air and exhaust gases and efficient heat exchange
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1975-07-28
Abstract: The elongated after-burner chamber is bounded at both ends by oscillation reflection walls. The downstream wall acts in heat exchange with the exhaust gas inlet chamber. An exhaust gas inflow tube passes centrally from the downstream to the upstream wall where it terminates in an annular nozzle with concentric annuli for the exhaust gases and for the preheated secondary air. This ensures a steady heat flow from the hottest point at the downstream end to the upstream end of the combustion chamber.

Title: Hydrofluoric acid baths for (de)polishing glass - contg. a dissolved, acid stable wetting agent
Inventor: NIEDERPRUEM HANS DR
IPC: C03C15/00
Filed: 1975-08-07
Abstract: Glass is subjected to chemical attack or polished by treating with an aq. soln. of HF contg. a dissolved wetting agent (I) which is resistant to acids. The mixt. can also contain H2SO4 or an inorganic acid fluoride and (I) is pref. a fluorinated anionic, cationic or nonionic surfactant used at 5-1000, esp. 50-300mg/l.

Title: Carboxylic thickeners for basic dye dispersions - for use on polyacrylonitrile or acid-modified polyester fibres
Inventor: REINHARDT FRIEDRICH DIPL CHEM
IPC: D06P3/52
Filed: 1976-02-20
Abstract: Dyeing or printing of opt. modified polyacrylonitrile or acid-modified polyester fibres is carried out with finely-divided cationic dye bases dispersed by means of surfactants, in which a polymer contg. carboxylic gps. is used as thickener. Compatibility problems when using conventional thickeners e.g. locust bean flour or starch products, which cause uneven or speckled dyeing, are eliminated and better colour yield obtained after high-temp. steam fixing, esp. when using dyes of triphenylmethane series. The thickeners are pref. aq. solns. of low-molecular polymerisation products of unsatd. mono- or di-carboxylic acids, e.g. (meth)acrylic, crotonic, fumaric, maleic acid, etc., or copolymers of olefins or lower alkyl acrylate esters with the monomers.
Patent DE-2609078-A1 (DE)
Inventor: HOECKELE MAX
IPC: H02G15/013
Filed: 1976-03-05
Abstract: A connecting device (19), which is to be arranged in a housing (4), is used for connecting the two cables (1 and 3). The trough-shaped housing (4), which is to be closed by a cover (5), is provided for filling with an insulating fluid. The bushings (13) for the metal-sheathed cable (1) rest in a moisture-tight manner on the metal sheath and on the trough (4), and the bushings (18, 20, 21) for the plastic cable (3) have a bush (20) which projects into the interior of the trough (4), impedes the passage of the insulating fluid to the cable insulation, and consists of insulating material. The trough (4) has two end walls (8, 9) which carry the bushings which are required for the insertion of the wires. One of the two end surfaces (8, 9) is provided with bushings which are arranged in a triangular manner. All the wires of multi-wire cables can thus be connected to one another in a single housing and the space in the housing can be filled with insulating fluid so that the amount of space required can be reduced. A screening grid (6) in the plastic trough (4) can effectively carry out the screening. In order to reduce the assembly time, the cover (5) is removable so that the wires can be connected in the open trough. <IMAGE>

Title: Colour CRT beam path adjusting magnetic module - has two opposite toroidal magnets with preset different flux density
Inventor: UENO TERUAKI
IPC: H01J29/70
Filed: 1976-03-05
Abstract: The beam path of a colour television cathode-ray tube is adjusted by a magnetic module with two opposite toroidal magnets mounted on the circumference of the tube neck. The flux density of the magnet on the input side of the electron beam is greater than that of the magnet on the output side. Preferably the density difference is 10 to 30%. Each magnet is typically of barium ferrite, and the two magnets are mounted opposite each other with intermediate non-magnetic spacers in between. The colour cathode-ray tube is of inline type. If permanent magnets are used, they are so magnetised that poles of alternating polarity appear along their circumference. In such case each magnet has a radially extending lug.

Title: Colouring foamed polyurethane or polyurea compsns. in black - with organic chromium complex Neozaponschwarz RE (RTM)
Inventor: SCHAPER HERBERT DIPL CHEM DR
IPC: C08J9/00
Filed: 1976-03-26
Abstract: Articles made from foamed or microporous polyurethane- or polyurea-base compsns. are black-colored using Neozaponschwarz RE (RTM) opt. in combination with carbon black (Neozaponschwarz RE is an organic chromium complex with OH gps. - contg. azo cpds. forming salts with ethoxypropylamine). Neozaponschwarz RE is introduced (in the form of a soln.) into the compsn. before the reaction in an amt. of 0.3-2.0 wt.% or 0.05-0.3wt.% when used in combination with carbon black. Neozaponschwarz RE reacts with diisocyanate gps. so that it becomes firmly anchored in the polymer and cannot be washed out or extracted with oils or fuels. Thus the prod. are esp. suitable for use in motor cars. The colouration is uniform.

Title: Compact automatic transmission for motor cycle - has reduction gear on motor to eliminate rear wheel reduction hub
Inventor: PLEYZIER GEURT
IPC: B62M9/04
Filed: 1976-03-31
Abstract: The light motorcycle or mpoed has a reduction gearing on its engine output shaft, driving a pair of variable spacing conves. The gear wheel is driven by a belt looped over the cones and a fixed ratio wheel on the rear hub. The reduction gearing eliminates the need for a variable reduction on the rear wheel and provides a simpler control. The cone spacing is controlled by pneumatic pressure from an engine driven impeller. The transmission ratio is then controlled w.r.t. torque.

Title: Rocket projectile with pivoted extending guide fins - has gas pressure actuated guide fins extended after launching
Inventor: BETHMANN KARL WILHELM DIPL ING
IPC: F42B15/00
Filed: 1976-05-26
Abstract: The projectile, esp. a rocket, has pivoted guide fins in the combustion chamber region. These fins are extended about the axis at right angles to the projectile longitudinal axis and held on the projectile casing. Each fin has axial actuator operated by the propellant gas pressure.

Title: IC engine fuel injection system - has device to determine fuel injection pulses or time related fuel supply, with exhaust gas composition probe
Inventor: SCHNUERLE HANS
IPC: F02D41/14
Filed: 1976-08-25
Abstract: In the fuel injection system, operating in dependence on the exhaust gas composition probe output, works either in synchronism with the crankshaft revolutions, or independence on speed and intake air volume. In the first instance fuel is supplied via electromagnetic injection valves, while in the second instance the fuel injection is determined by a control pressure. The probe output signal is compared with a threshold voltage, and an in tegrator circuit in series-connected to the comparator, which generates a signal affecting the injected fuel volume. In front of the threshold voltage comparator is connected a circuit for shifting the time point of parator is connected a circuit for shifting the time point of the comparator signal zero passage in at least one direction, in order to shift the probe output signal.
