Title: Motorcycle windscreen with impact movable pivot mounting - has screen either held between bendable U=shaped clips or released by flexible screen portion
Inventor: VETTER CRAIG WILLIAM
IPC: B62J17/04
Filed: 1978-02-16
Abstract: The windshield is either pivotally mounted or breakaway mounted along its bottom edge to a motorcycle fairing. It is releasably held in an upright position by sides of the windshield which allow the windshield to separate and either pivot forward or fly away from the rider upon the rider striking the windshield. The windshield can be held held by bendable U-shaped clips, and the release of the wind shield is achieved partly through flexing of the wind shiled and partly through the bending of the clips. A resilient windshield can be held between a pair of rigid U-shaped brackets in a flexed state, and release of the windshield upon impact is achieved solely through the ing of the windshield.

Title: Low speed transmission for utility vehicle - has inching drive via hydraulic transmission from power take=off
Inventor: ALBERTINI WILHELM
IPC: B60K17/10
Filed: 1978-02-27
Abstract: The transmission of the utility vehicle has the ancillary equipment driven by a set of hydraulic drives from a main PTO. Inching control is provided by a separate hydraulic pump linked to the PTO to drive a reduction gearing and a hydraulic motor on the road wheel transmission. The vehicle is able to travel at normal speeds on roads and with a careful inching control using the hydraulics.

Title: Pulmonary diagnostic system - comparing carbon di:oxide concn. difference and breath vol. by microcomputer
Inventor: SMIDT UDO DR MED
IPC: A61B5/087
Filed: 1978-03-21
Abstract: A system of pulmonary diagnostics, esp. of pulmonary emphysema, combines the continuous measurement of the concn. of a respiratory gas component and of the respiratory vol. Differences in concn. are determined from start to end of the expiration. An expiration vol. curve section is determined and recorded as a function of the preceding inspiration vol. which corresponds to a defined section of the concn. difference. This merely requires a number of breathing cycles of different depth to provide significant indications about the presence of emphysema.

Title: Phthalide prodn. by hydrogenolysis of 3-chloro:phthalide - with recycle of excess hydrogen after mixing with oxygen and passing over catalyst
Inventor: ENGLAENDER FRITZ DIPL CHEM DR
IPC: C07D307/88
Filed: 1978-11-04
Abstract: The parent patents describe prodn. of phthalide (I) by hydrogenolysis of 3-chlorophthalide (II). In this addition the unreacted H2 is mixed with 0.05-4 vol.% O2, passed over a catalyst (esp. finely-divided Cu) at 30-200 degrees C then recycled to the reactor. The recycle gas is pref. dried with KOH before return to the reactor and opt. is additionally passed over another catalyst bed at 80-200 degrees C. In the parent patent, direct recycle of excess H2 causes a redn. in hydrogenolysis rate. This is avoided by the present method and the rate remains at its initial value.
Patent DE-2855753-A1 (DE)
Title: Feed roller assemblies for fibrous material - having air jets directed against the surfaces to prevent roller lap formation
IPC: B65H51/10
Filed: 1978-12-22
Abstract: Feed-roller assemblies comprising >=2 rollers around which a tow or sliver is partially wrapped have a series of air jets directed onto the roller surfaces to prevent lapping of loose fibres or filament ends. Jets directed against the section of a roller covered by the tow or sliver are oriented in the direction of motion, whilst jets directed against uncovered sections are oriented in opposition to the direction of motion. further jets may be directed against the line of contact between two rollers to promote the complete transfer of material from one to the other. The jets prevent the formation of roller laps, whilst actively assisting the transport of the fibrous material and are partic. useful in the breaking zone of a stretch-break tow converter.

Title: High speed matrix printer - has array of electrodes with not more than three points printed at any given time and includes sequencing routine
Inventor: KOERNER WOLFGANG DIPL ING
IPC: B41J2/385
Filed: 1979-03-14
Abstract: A high speed matrix printer has an array of electrodes to write alphanumeric characters onto prepared paper with a metal coating. For higher writing speed only up to three spots are printed at a time and the writing speed is set higher over the lines as well as the line indexing. The three point print process only uses a simple logic with little-cross-talk and simple interconnections. The writing speed can be increased without danger of losing definition. The writing head is indexed at a speed less than the space between writing each group of three points. The number of points written is passed to a sequencer and an event function is derived which enables more time space to be allocated to enable the remainder of the character to be written of incomplete.

Patent DE-3017488-A1 (DE)
Inventor: WATANABE OSAMU
IPC: F24F1/00
Filed: 1980-05-07
Abstract: The air cooler comprises an upper water-cooling chamber (3) and, arranged below it, an air-cooling chamber (4). Situated in the water-cooling chamber is a filling body (5) and in the air-cooling chamber likewise a filling body (11). The air passing through the water-cooling chamber serves to cool the water, with the aid of which the air passing through the air-cooling chamber is cooled. The water is sprayed onto the filling body (5) by a spraying device (6), the air being warmed and blown out through the opening (8). The water thus cooled passes onto the filling body (11) and cools the air which can be used for cooling purposes. It is a precondition that the air to be cooled is dry. The cooled air is used for example for cooling electrical appliances. The water passing through the cooler (11) is collected and returned to the spraying device (6) by means of a pump (18). The evaporated water is replaced. <IMAGE>
