Inventor: NAKAJIMA NOBUYUKI
IPC: F04C18/344
Filed: 1991-05-23
Abstract: The compressor has a cylinder with a curve ring with open face sides closed by two side parts, a rotor rotatably located in the cylinder with an outer peripheral surface and having several radial vane slots in which the vanes are located.

Title: Rubbish disposal which recovers and recycles useful materials - by forming briquettes, sorting and grading according their usefulness, then grinding and mixing with bonding agent
Inventor: DIJK HENDRICUS JOHANNES MARIA
IPC: B65F5/00
Filed: 1991-09-21
Abstract: To dispose of rubbish, it is collected where the rubbish accumulates to be ground and formed into briquettes. The briquettes are sorted and graded according to their usefulness. The useful briquettes are ground, and mixed at least partially with a bonding agent, to be converted into a new prod. The other briquettes, with no useful application, are disposed of. When the briquettes are ground, paper, wood and/or plastics are sorted out, to be mixed with a bonding agent for board mfg. ADVANTAGE - The technique gives recovery and recycling of useful materials, reducing damage to the environment, and it gives a supply of material for mfg. board and the like. The accumulation or rubbish at building sites is reduced. The briquette form allows other industries to take in materials suitable for their use.

Patent DE-4139218-A1 (DE)
Inventor: KAADEN JUERGEN DIPL ING
IPC: G05B19/401
Filed: 1991-11-29
Abstract: The position of tape loading and unloading mechanisms is determined using position switches whose output signals are coupled via a resistance network. The differences in voltage between different positions is small, thus making interpretation unreliable. The aim of the invention is to provide increased reliability, without the need for tightly toleranced network resistances or a high-stability network voltage. In a calibration procedure, the voltage associated with each individual position is measured at the network output, input into a memory and used as a target value for normal operation. The invention is applicable in particular to analogue or digital video or audio cassette recorders.

Abstract: In a component system for constructing clamping devices there is a basic unit (1) extending in the X-Y plane and a clamping component (2) which can be secured thereto in various selectable positions. The basic unit (1) has projections (6) regularly arranged in a grid in the X-Y plane with reference surfaces (6a and 6b) acting in the Z direction. Connecting components may extend between the projections (6) and the clamping component (2). Either the distance between reference surfaces of neighbouring projections and that. From the reference surface from one projection is the same or the distance between reference surfaces from one projection is the same or the distance between reference surfaces of neighbouring projections is an even multiple of the distances between the reference surfaces to the same projection. This makes the component system highly flexible and provides simple and easy clamping facilities.

Patent DE-4207573-A1 (DE)
Inventor: OPPAT JOERN
IPC: G06F13/38
Filed: 1992-03-10
Abstract: A parallel interface is disclosed for connecting data processing machines to each other or to peripherals, in particular for connecting a personal computer to a printer. The parallel interface has two status information lines, disconnectable line drives and control lines (SLCT, SLCTIN). For a predetermined direction of data transmission, the beginning of data transmission at the emitting machined is signalled on a first control line (STBN) in a predetermined direction of data transmission and the end of data transmission at the receiving machine is signalled on a second control line (ACKN). In order to achieve a high transmission speed bidirectional interface, both status information lines (SLCT, SLCTIN) are able to disconnect the line driver of the machine which is at the receiving side at any given moment, switching over the data transmission direction. Once the data transmission direction has been switched over, the second control line (ACKN) at the now emitting machine is used in the same way as the first control line before the data transmission direction was switched over, and the first control line (STBN) of the now receiving machine is used in the same way as the second control line before the data transmission direction was switched over.

Title: Theophylline recovery from tabletting dust - by extraction with aq. ammonia, used as diuretic
Inventor: KRAHNEFELD HELMUT DR
IPC: C07D473/08
Filed: 1992-04-21
Abstract: Isolation of theophylline (I) from tabletting dust is effected by partially dissolving the dust in aq. NH4OH; filtering off insolubles; removing NH3 under vacuum at a temp. below 50 deg.C; and separating crystallised (I) from the mother liquor. Pref. the molar (sic) ratio of NH3 to dust is 1.5-3:1. The NH3 is driven off at 40-50 deg.C and absorbed in water to obtain aq. NH4OH for the next batch. USE/ADVANTAGE - (I) is used as a diuretic. The process is simple, environmentally safe, and gives high recovery yields (e.g. 96%) of high-purity (I). In an example, dust comprising 240 kg (I), 30 kg corn starch, 10 kg lactose and 20 kg other insolubles (including CaCO3 and Mg stearate) was added to a mixt. of 2000 litres H2O and 250 litres of 29% NH4OH. The mixt. was stirred for 30 min., filtered, and stripped under vacuum at 40-50 deg.C while stirring. The mother liquor was flushed with air for 3 hr. Crystals were sepd., washed with H2O and dried to give 231 kg (96%) of (I).

Filed: 1992-05-15
Abstract: A mechanism for adjusting the diopter setting of a finder assembly having an objective optical system 10 and an eyepiece optical system 11 includes an object side image forming position adjusting device 13 which adjusts the position 12 where an image is to be formed by the objective optical system 10. The mechanism effectively compensates for any change that occurs in the position where an image is formed by the objective optical system 10 due to temperature or humidity variations. Thus, the problem of plastic lenses having their focal lengths extended in a hot and humid environment is solved by the invention. Alternatively, the adjusting device may be a movable retroreflector (15, Figs 3, 3A), or a movable objective lens (17, Fig. 4, 18, Fig. 5). <IMAGE>
