Title: Air outlet unit for ventilation systems - ejects air upwards and sidewards and has rotary slide sealing unit to adjust outlet
Inventor: MINDERMANN HERMANN
IPC: F24F13/06
Filed: 1976-11-03
Abstract: The air outlet is for ventilation- and/or air conditioning systems, and has an upwardly directed air guidance. The outlet has a housing (12) with an air inlet socket and air outlet sockets. The housing outlets eject a vertical air jet upwards (4), and a horizontal jet sidewards (13). The upper air outlets have a rotary slide sealing unit (24), to adjust the outlet for the vertical jet. The inlet socket opens into an inner chamber in the housing, which is connected via an adjustable air outlet (32) to an external chamber. This is formed between the inner chamber and the housing wall (12c), which has the air outlets (13, 14).

Title: Electrical machine rotor to shaft coupling - uses elastomer bushes to avoid disturbance torque problems
Inventor: UTECHT MANFRED DIPL ING
IPC: H02K1/30
Filed: 1976-11-18
Abstract: Elastomer bushes are used in the coupling of the rotors of electrical machines with pick-off shaft. The rotor of a machine (1) has a boss (4) with a hole that locates on a drive shaft.

Title: Testing of structures on surfaces of electrical modules - has structures scanned and tested for observance of salient factors, e.g. spacing, angles, straightness
Inventor: RICKER THOMAS DR RER NAT
IPC: G06V10/36
Filed: 1977-01-05
Abstract: The structure testing method is applicable to structures on surfaces of electrical modules or to auxiliary means for production of the subassemblies. The existing actual structure is scanned and intermediately stored. The structure so obtained is tested for observance of specified constructional rules relating to the structure building, such as syntactic connection between adjacent picture elements. Deviations from the rules indicating structure faults are detected. A practical example is afforded by a mask structure consisting of black regions, in front of a white background. The factors to be tested are accuracy of corner angles, straightness of edges and min. separation of the black regions which can be isolated from each other or interdependent.

Title: Distance indicator for sports competitions - incorporates electric conductor tracks positioned within permissible landing area for jumper or thrown object
Inventor: KLOTZKI ULRICH
IPC: A63B71/06
Filed: 1977-01-08
Abstract: Distance indicator appts. is used for sports competitions such as long jump, discus, hammer or shot putting contests etc. A number of electric conductor tracks are positioned within the permissible landing area for the jumper or for the object thrown.

Title: Anti-implosion ring for television tubes - comprises steel ring coated with aluminium and then baked enamel for protection against corrosion
Inventor: LEHMANN HANS-JOACHIM
IPC: H01J29/87
Filed: 1977-05-17
Abstract: A coating which provides protection against corrosion is applied to an anti-implosion frame employed on television tubes. Frame is a ring of steel strip, which is coated with a layer of Al by a conventional immersion process, followed by a layer of baked enamel.

Title: Noise reducing construction for vehicle - uses hollow panels through which air is drawn to intake system
Inventor: ABE EIICHI
IPC: F02M35/14
Filed: 1977-10-24
Abstract: One or more of the panels surrounding the motor space of vehicle is built as an enclosed chamber with thin double walls (1), and an air inlet (2) and outlet (3) ports.

Title: Time buffer device for incoming series bit trains - has writing and reading store controlling number of signal stores
Inventor: HUMMEL JAN ING
IPC: G06F5/06
Filed: 1978-01-19
Abstract: The bit trains are stored in one or several signal stores, and collected from the store(s) in the same order as they were stored. One single writing-reading store (32) is provided for several independent and asynchronously operating signal stores. It has storage locations for information storage (IS) and further storage locations for determination of position of a newly arrived signal, and the position of a signal to be read out. When a signal is to be written, its position differs by one from that of a signal to be read out. When a signal is read out the position of the next signal to be read out is nearer by at least one to the position of a signal to be written in. When operating any of the available stores, the writing-reading store (32) applies the address of the respective store and connects its last state to its outputs connected to the inputs of an intermediate store (33). This state is stored in it on reception of a pulse at its transfer input (E), and switched to its outputs.

Title: Superalloy substrate plasma sprayed with protective coating - followed by hot isostatic pressing which consolidates the coating
Inventor: WALLACE FRANCIS JOHN
IPC: C23C4/18
Filed: 1978-07-19
Abstract: A coating of MCrAlY, where M is Ni,Co or Fe, is applied by plasma spraying onto a superalloy substrate. The coating contains pores, voids, and other defects, some reaching surface of the coating, which is then sealed. Hot isostatic pressing is then used to close the defects in coating thereby considerably improving the protective quality of coating, and the seal prevents the atmos. used in pressing from entering the pores etc. Seal is pref. a metal envelope esp. a metal which improves the protective quality of coating, the hot isostatic pressing pref. also causes diffusion of metal into coating. Metal is pref. Cr or Al and/or is an electroplated metal, sealing may alternatively be achieved by cold working the surface of the coating. The sealing envelope may also be a metal foil, esp. of Al. The final protective coating, is free from surface and internal defects, and has a resistance to oxidn. and corrosion at least equal to that of a similar compsn. obtd. by vacuum metallisation.

Patent DE-2839812-A1 (DE)
Title: Millikan test medium - consisting of argon instead of air for better discerning of oil droplet strings
Inventor: OHLMEYER MANFRED ING GRAD
IPC: B01D46/42
Filed: 1978-09-13
Abstract: A visual oil droplet string method (Millikan test) is commonly used to check filters for gases with toxic components e.g. radioactive dust particles. This test fails, however, when the filter outlet is at the bottom because the oil mist is lighter than air and it becomes impossible to discern the strings of oil droplets. This problem has been solved by using as the carrier medium a gas which has a greater specific gravity than air, pref. argon. This makesit possible to produce stable strings of oil droplets under all circumstances for tracing back any leakage.

Title: Closure for container with neck portion - has inner resilient seal compressed by outer cap to form seal around neck
Inventor: LOOKER EDWIN CREIGHTON
IPC: C12G1/08
Filed: 1978-09-13
Abstract: A closure (10) for a necked container, such as a bottle, comprises an outer cap (11) and an inner resilient sealing member (12) provided with a slit (22). The inner member is displaceable within the outer cap from a position in which it can be fitted around the neck of the container to a position in which it is compressed by the outer cap and is thus caused to form a seal around the neck. The slit acts as a vent valve when the closure is in sealing engagement with the container.
