Patent DE-2645219-A1 (DE)
Title: Batch mixing of gases - with at least one component being introduced to isentropic opening at supercritical pressure
Inventor: GUTIERREZ JAVIER DIPL ING
IPC: B01F23/10
Filed: 1976-10-07
Abstract: At least one component being mixed into a gaseous system is measured on a time basis by isentropic expansion from super-critical pressure. The process is used to prepare a gas mixt. of known compsn. where one component is available at a high pressure. It is a simple measuring system based on time only, and can be adaptable to automatic control. Pref. a low pressure gaseous component is fed into a mixing vessel at known pressure and volume. A second component, at above critical pressure, is fed into the mixing vessel through an expansion nozzle giving frictionless isentropic expansion from the high to the lower pressure. By this means, the amt. of high pressure gas flowing into the mixing vessel is dependent only on the time of flow. By duplicating the mixing vessel and providing automatic control valves, the system may be made continuous.

Title: Lifting mechanism for door - has spring positioned between hinge sections and catch coupled to handle to push door down on closing
Inventor: HESSE KLAUS
IPC: E05F7/02
Filed: 1976-10-22
Abstract: The door fitting and locking mechanism ensures that carpets can be laid flush and close with door underside edge. A spring is placed between door hinge halves so that the helical spring encloses the hinge pin and pushes it out of its socket. The door catch can be connected to the door handle for pushing the door down on closing. The catch spring can be sufficiently strong for pushing door down by its wedge action. A rubber seal can be fitted to the door underside for pushing against the floor when the door is closed. The resistance between the catch and frame can be reduced by a roller.

Title: Infinitely variable chain gearing - has small radially movable sprockets mounted on discs secured to parallel shafts
Inventor: ZVETKOV ATANAS ZVETANOV DIPL I
IPC: F16H9/24
Filed: 1976-11-15
Abstract: The infinitely variable chain gearing has two parallel shafts to each of which is secured a disc supporting an annular array of chain sprockets. The sprockets are supported by respective radial slides movable by respective radial screws from a common gear rotatable on the shaft. At least one of the sprockets is geared to a fixed radial rack so that the sprocket rotates only when its radial position is changed. A chain trained around the two arrays of sprockets transmits torque between the shafts and the transmission ratio is changed by synchronized operation of the two common gears.

Title: Correct address and word assignment recognition in data memory - involves single error correcting and double error detecting facility
Inventor: HAEUSELE HANS DIPL ING
IPC: G06F11/10
Filed: 1976-12-08
Abstract: The apparatus includes a device to form a binary coded error identifying character by comparing the test bits made by the first and second test-bit generators (6, 7). An error location decoder produces error signals and correction signals which are supplied to a correcting device (13) to correct erroneous bits of the word read from the memory. A data block is formed by linking up the address and the memory word. It is connected to each input of the two test-bit generators. An error is detected in the region of the address, the error location decoder transmits an error signal.

Title: External coating of glass bottles with plastic - where large scale coating plant is fed with hot bottles leaving glass moulding machine
Inventor: SCHULZE ERNST
IPC: C03C17/32
Filed: 1977-10-12
Abstract: On leaving their mfg. machines, the glass bottles are hot, and they travel through a cooling and stress-relieving station (a) to a plastic coating station (b), held at 60-180 degrees C and in which the bottles are kept apart from each other on a conveyor. The bottles then travel through a heating station (c) so the plastic particles are melted at 120-280 degrees C to form a continuous coating; and the coated bottles are fed to one or more packing stations. In the pref. plant, a printing station is located between stations (a,b) and is followed by a heated buffer store for holding bottles prior to coating (b). On leaving their mfg. machines, the bottles may be treated with organic or inorganic metal cpds., and/or chemically- or thermally-hardened, prior to coating with plastic. A relatively low amt. of thermal energy is used in this simple coating process.

IPC: C02F11/121
Filed: 1978-01-09
Abstract: Force feed dewatering plant for excess and/or raw sludge, with forced mixing of the sludge or their mixtures, brings about a slow flow through having a rectangular, circular or triangular cross-section around the wall of which a commercially obtainable filter felt is stretched, and extends over an appropriate length of the trough. The plant reduces considerably the costs of installation and increases the ratio of solid matter in the delivered sludge, the vol. of which may be reduced from 100% to 25%, with solid matter raised from 2 to 8%. The trough is formed by a rustless net with a mesh of about 6/6 cm. The filter fleece lining it is fastened so as to be easily replaceable. The mixing and the slow flow are effected by a motor driven worm. The dewatered but still pumpable sludge is delivered for the next operation at the outlet and the clear filtrate is either recycled or put to waste.

Title: Capacitor connecting wire shielding - during fluidised plastic bed coating technique by paper or plastic strip
Inventor: KNAB HEINRICH
IPC: H01G2/12
Filed: 1978-08-25
Abstract: The Parent Patent described a fluidised bed technique for applying a plastic coating to flat capacitors, esp. those with polyethylene terephthalate or polycarbonate as the dielectric. In this patent of addn., the connecting wires of the capacitors are shielded during the passage through the bed close to the base surfaces of the capacitors by a covering of paper, plastic foil or wax. This prevents the undesirable deposition of resin on the wires without obstructing the coating of the base surfaces.

Title: Height adjustable stand for X=ray lamp - has telescopic column movement to leave settings in other directions unaffected
Inventor: WEINER RUDOLF
IPC: F21V21/22
Filed: 1978-11-15
Abstract: A stand has a tubular U-shaped base (1), to the centre of which is fixed a vertical tube (6). Inside the tube slides an inner tube (7), to form a telescopic vertical member. The inner tube has a horizontal extension (8), to the end of which a device such as an X-ray lamp (9) can be mounted, pivotable about both a horizontal axis and the vertical axis (11).

Title: Vehicle wheel play measurement - using sliding wheel supports and evaluation of their axial force and displacement functions
Inventor: GLOECKNER HERMANN
IPC: G01M17/06
Filed: 1978-11-30
Abstract: A measuring device determining static vehicle wheel suspension play has horizontally sliding wheel support plates and enables rapid, economical and accurate play measurement resulting in a numerical measurement output obviating subjective factors. Two support plates (1, 2 or 3, 4) per whel (6, 7) are placed one behind and inclined w.r.t. the other to form prism shapes on which the wheels rest. One or both are able to be slid parallel to the wheel axle. The axial movement distance of the support plate is measured by a sensor (17). A further sensor (14) measures the force producing the axial plate movement. an indicator (16) connected to both sensors displays the distance of displacement as a function of the axial force. Evaluation of the distance -force curve yields a quantified play measurement.
