Title: Photographic print camera with lateral image inversion - employs L=shaped mirrors to correct left to right inversion of image on viewing screen prior to exposure
Inventor: TOKUDA KANJI
IPC: G03B27/70
Filed: 1990-02-06
Abstract: The device employs a pair of plane mirrors (50,51) mutually inclined at 90 degrees and set with their common edge at 45 degrees to the principal axis of the light path.

Patent DE-4040812-A1 (DE)
Inventor: GAST RALF
IPC: G08B13/193
Filed: 1990-12-14
Abstract: Miniaturised passive infra-red movement detector. Passive infra-red movement detectors are primarily used in intruder alarm installations. In order to obtain a wide range of coverage, these devices make use of Fresnel lens arrangements or mirror optics which substantially determine their size and hamper miniaturisation. The novel device is designed to be substantially smaller than prior-art passive infra-red movement detectors despite having a wide range of coverage. A detector (1) constructed as a multi-element sensor in the form of one or more lines is arranged behind a convergent lens (2). Thus the coverage (4) in front of the convergent lens can be divided into several small fields of view (4.1 to 4.8) of high sensitivity in a substantially smaller format.

Title: Sorting plastics scrap, ground to approximately uniform size - by computer comparison with reference values, of e.g. HF heating or laser transmission measurement, to control airjet or mechanical separator
Inventor: BARICH GERHARD PROF
IPC: B07C5/34
Filed: 1991-02-22
Abstract: Process and arrangement for sorting plastics scrap, which is first communited to approximately uniform size. The pieces are individually measured properties which are compared with reference values by computer, whichthen controls sorting equipment to divert individual pieces into collecting bins according to type of plastic. Identification measurements may be by response to or transmission of low, medium or high frequency vibtayion, of ultrasound or of laser illumination. It may also be by chemical measurement (not further specified). If high frequency heating is used, weight and starting temp. may be measured, together with the final temperatures, by non-contact thermometer, after a fixed time under constant heating conditions, which utilised the differing polarities of separate types of plastic. The sorting mechanism may be an array of air-jets or mechanical means, e.g. arms grips, slides, or a series or flap valves over the collecting bins. ADVANTAGE - Compared with the hydrocyclone, this process does not require uniform particle size and shape for precise functioning. Compared with the flotation processes, this is speedier and is not limited to sepg. polyolefins from the rest.

Title: Prodn. of iron ore pellets, useful in metallurgical industry - comprises recirculating cover elements protecting the grate structure from heat
Inventor: PAPACEK HERBERT DR
IPC: C22B1/20
Filed: 1991-03-22
Abstract: Prodn. of iron ore pellets consists of loading green pellets onto a recirculating cover which is made up of bodies of identical geometrical form and size within close tolerances of a travelling grate, where they are dried, roasted and cooled. At the exit from the grate the pellets are sepd. from the cover bodies whose size is at least 1.5 times the mean pellet size and then fed to the smelting process. The cover is pref. formed of spherical bodies with the diameter about 1.5 to 2.5 times the mean pellet dia. Worn out balls from ball mills can be used for such a cover. Alternatively, ceramic balls with the diameter 2 times the mean pellet diameter can be used. Aluminium oxide could be the material of such balls. The roasted pellets and ceramic balls are separated from one another by means of screens. USE/ADVANTAGE - Used in the metallurgical industry. Its use enables higher temp. to be used for pellet preparation, resulting in higher pellet quality and (as a consequence) in a more efficient smelting process, with reduced coke consumption.
Patent DE-4111738-A1 (DE)
Title: Appts. for extinguishing oil well fires in sandy terrain - used to smother flame and uses integral cooling units to quickly reduce temp. of the immediate area
Inventor: ERABI TAHER
IPC: E21B35/00
Filed: 1991-04-06
Abstract: Appts. is claimed for extinguishing burning oil wells, partic. suitable in sandy terrain and where a clear area of 3-5 m radius is available around the fire. The novelty of the appts. is that oxygen is denied the flame, and the controlled cooling of the flame. Sudden removal of oxygen from the flame is achieved by positioning the dome shaped steel construction with a cylindrical under section, over the flame by means of a helicopter or other lifting means. The 1200 kg weight of the construction, forces a sealing ring into the ground. A conical, punctured tube, with a venturi extends down into the centre of the dome structure, and is positioned over the flame. Controlled release of coolant removes energy suddenly in the immediate vicinity of the flame, causing the fire to be extinguished. Eight coolant cylinders each contg. 6 kg of coolant, are positioned around the lower cylinder, and a further 12 positioned around the steel sheet dome structure. Once the flame is extinguished and the temp. within the dome has reduced sufficiently, a door gives access to the oil well head which can then be secured and shut off. The dome can then be lifted and used at another location. ADVANTAGE - Extinguishes fires very quickly and economically. Can be used several times.
