Patent DE-2425856-A1 (DE)
Title: Tape recorder automatic position finder - seeks required position on tape in response to keyed in number
Inventor: SCHOLZ WERNER DIPL ING
IPC: G11B27/13
Filed: 1974-05-28
Abstract: A magnetic tape driving equipment with an automatic position search facility, where a position on the tape is found in response to a keyed in number, deduces the position from the number of turns effected by both spools. A photocell unit is associated with each spool drive and the outputs fed to an adder and thence to a frequency divider. A count is accumulated in a storage unit, and when this corresponds to the count in another similar storage unit the tape is stopped. The second storage unit is filled from a hand key panel allowing the insertion of three decimal digits. A decimal to binary converter transfers the information to the storage unit from the handkeys. Another transducer holds the demanded number during fast feed forward over the tape leader and also zeroes the tape feed count. In addition, logic facilities are provided for backwards and forwards tape drive, and for displaying the position reached.

Title: Adjustable brake lever for pedal cycles - has adjuster screw to determine distance between lever and handle bar grip
IPC: B62L3/02
Filed: 1974-07-17
Abstract: In order to comply with certain country regulations stating that the hand brake level must be maintained at such a distance from the handle bar grip to suit users hands, the lever is provided with an adjuster screw (20) whose free end (21) rests against the hand lever pivot block (12). Tightening the screw brings the hand lever closer to the handle bar grip (16). The screw head is accessible via a bore (22) in the hand lever. The stop screw can instead bear against a bolt at its far end, made of harder metal to preserve the softer lever casting.

Title: Motorcycle component tubular sections - contain non-metallic damper material to reduce vibration in frame or handlebars
Inventor: RAFL JAN DIPL ING
IPC: B62K11/00
Filed: 1974-11-08
Abstract: The tubular sections are for handle bars and foot rests of motorcycles or similar vehicles. The interior of the tubes is filled partly or completely with a non-metallic dampener material e.g. soft synthetic foam. The material reduces vibration, and provides a rust-proofing. The arrangement is used particularly in the tubes comprising the frame in the engine region, and is injected after the frame has been constructed via suitable apertures. Where weight is not critical a glass fibre laminate may be used, and is partic. useful for metals such as aluminium which are prone to fatigue failure.
Patent DE-2460312-A1 (DE)
Title: Flue gases purificn. - by adsorption of so2 and other contaminants on clouds of airborne carbon dust
Inventor: NOACK ROLF DR ING
IPC: B01D53/04
Filed: 1974-12-20
Abstract: In a process for removing SO2 and other contaminants from flue gases, in which the gas is brought into contact with an adsorbent which is later thermally treated to regenerate it by desorption, the adsorbent is blown into the flue gas in the form of dust with high energy after the flue gas passes through a primary dust removal plant. After a sufficient residence period the gas is passed through an electrofilter which seps. the adsorbent with the other residual dust particles in the gas and desorption is carried out in a fluidised bed. Whereas the systems employing beds of carbon particles, a high quality (and therefore expensive) grade of carbon is required for resistance to attention, high crushing strength, ignition temp. etc., only low grade carbon is required. The carbon is more easily handled, introduced into and removed from the gas. Adsorption takes place in a duct and no adsorber vessel is needed. Small particle sizes give fast reaction times leading to lower residence times and higher loading rates. Regeneration is considerably easier.

Title: Parallel inverter having centre tap - with auxiliary thyristor connected via commutating inductor between tap and diode-diode junction
Inventor: RAO HATTANGADY VASANTH
IPC: H02M7/515
Filed: 1975-03-20
Abstract: In a parallel inverter having a transformer with centre-tapped primary winding, an auxiliary thyristor is connected via the commutating inductor between the centre-tap and the junction of two series connected diodes bridged across the primary winding. A second winding on the commutating inductor inductively coupled to the first is inserted in series with a D.C. source. The inverter can operate with any desired width of the output voltage pulse, and this pulse width can be chosen to be in the region of minimum harmonic distortion or to provide elimination of any undesired harmonic. Clamping of flux in the transformer core permits full utilization of the core over a wide range of starting and operating conditions.

Title: Optical density measurements of diesel exhaust gas - utilise heated rotating discs in front of measuring chamber orifices (SW120176)
Inventor: ADOLPH DIETRICH DIPL PHYS DR
IPC: F02B3/06
Filed: 1975-03-21
Abstract: The exhaust gas from Diesel engines is measured by the obscuration of luminous rays. Particles of soot or dirt on the detectors cause erroneous readings. A burner is used to burn the particles which settle on a rotating disc in front of the detectors. The engine exhaust gas passes through a measuring chamber (10) from inlet (13) to outlet (14) while pure air is pumped (12) into a reference chamber (11) to maintain a slight pressure. Rays from a light source (25) are directed by mirros (26, 27) through filters (28, 30) and lenses (29) towards the chambers which have inlets (15, 19) and outlets (16, 20) through which the rays pass to an optical system with a photo sensitive detector. Transparent rotating discs (21, 22) in front of the ray inlet and outlet orifices are heated by two hydrogen or propane burners (40, 41) to burn the soot.

Title: Tube bundle for direct contact heat and mass transfer processes - comprises central tube surrounded by hexagon pattern of active tubes
Inventor: BRAUER HEINZ PROF DR ING
IPC: F28F25/08
Filed: 1975-04-12
Abstract: The invention relates to a compact tube bundle system made up from elements comprising a central tube surrounded by 'active' tubes, each in contact with the other, and each element having a common liquid inlet and liquid outlet. The basis of the design is an element consisting of a central tube closely surrounded by one or two layers of 'active tubes' arranged in hexagonal formation, all disposed vertically. The central tube is closed at both ends and above it is the liquid inlet for that element. Used for heat transfer and matter transfer processes, including chemical reactions, involving direct contact between gas and liquid phases. As compared with packed columns, or columns having tube bundles with tubes attached to tube sheets, the new design offers a compact and inexpensive construction, low pressure drop on the gas side and good contact between the two phases.

Title: Ski brake compont for extra snow friction - is plastics sheath spring wire cylindrical or square section coil with axial rod
IPC: A63C7/10
Filed: 1975-06-09
Abstract: The braking component of a ski brake consists of a coiled spring (3) of either round or rectangular cross section. The spring coils are either cylindrical, tapered or looped to form a ring. The brake component encounters a maximum amount of surface area when it is contact with snow or ice, hence friction is greater then. An axial rod (1) is anchored inside the spring coil (3), and is attached to the ski brake mechanism which is part of the ski binding. To provide added protection for the brake spring, the coil wire can be clad in a plastic sheath, or the whole coil can be covered with a plastic sleeve.

Title: Mobile spray head for cleaning or lubricating compression moulds - having mutually perpendicular introduction and retraction paths
Inventor: KEIM KARL-HEINRICH
IPC: B29C33/72
Filed: 1975-06-16
Abstract: A mould spraying device for a compression moulding machine is fixed on one mould part of the machine or a connected part. It comprises a support unit for a spray head supplied with outlet orifices for delivering air, and/or water, and/or lubricant to the mould parts, and can move linearly along a path parallel to the plane of separation of and between the mould parts when the mould is opened. The construction is modified so that the spray head can also be displaced along a retraction path perpendicular to the path of introduction in such a way that it can be removed before closure of the mould parts from the zone of relative motion of that mould part not supporting the spraying device as well as the components fixed thereto. In compression moulding machines in which the movable mould carries attachments, the space necessary, particularly the height, for the retraction of the mould spray unit before mould closure can be very considerably reduced.
