Title: Cotton plants growth regulation - within N,N-di:methyl-piperidinium salt applied from the air and/or at blossom time
Inventor: JUNG JOHANN
IPC: A01N43/40
Filed: 1978-04-10
Abstract: In a process for regulating the growth of cotton plants, the plants are treated with an N,N-dimethylpiperidinium salt applied at a rate of 5-490 g./ha. with the aid of an aircraft or of a ground-effect machine (i.e. hovercraft). Regulation of growth of cotton plants by application of 5-490 g./ha. of an N,N-dimethylpiperidinium salt as soon as 2-20 white or yellow blossoms are present per 10 metre run of cotton plants is new irrespective of the method of application. Application at a precise but easily recognisable stage of development enables the active ingredient to be used at a relatively low rate of application. Application at the specified stage of development inhibits vegetative growth and promotes generative development, resulting in an increased crop. The strength of the cotton capsule epidermis is increased, thus increasing resistance to capsule rot. Surprisingly, application from above by means of aircraft or ground effect machines (which could be expected to be inefficient because active ingredient does not fall directly onto lower leaves) is effective even with low application rates of 5-490 g./ha.

Patent DE-2904960-A1 (DE)
Title: Gas turbine engine lubrication system - includes by=pass duct controlled by valve programmed to dump excessive oil flow at engine idle
Inventor: MILO GEORGE T
IPC: F01D25/18
Filed: 1979-02-03
Abstract: A bypass duct (11) provides a return passage to the sump (12) for oil flow pump (3). The duct (11) is controlled by a valve (13) which is constructed to be open at oil pressures representing idle speed or lower. The orifice of the valve is designed to allow the return of enough oil flow to compensate the poor scavenging capability of the oil distribution system at idle engine speeds and to supply full oil flow at higher speeds. In order to prevent an accumulation of oil during the gradually declining speeds which occur at engine shutdown, a check valve (14) is placed in the main supply line (15) from oil pump (3) at a position downstream of the bypass valve (13). The check valve (14) is designed to close at a pressure which indicates that the engine is at low compressor rotor speed. Oil from the pump (3), which flows during the later stages of engine deceleration, is returned through bypass duct (11) and a build-up within bearing housing (5) is avoided.

Title: Opto-electronic surface monitor for cold-rolled flat material - uses self-scanning image sensing diode row and has continuous analyser
Inventor: KECK ROLAND DIPL PHYS DR RER N
IPC: G01N21/89
Filed: 1979-03-22
Abstract: The method of testing surfaces of cold moving flat material, esp. in a cold-roll process, involves applying the image of the surface to a diode row whose diode current is continuously analysed. The expense of the optical and electronic systems as well as the required space are considerably reduced compared to conventional systems without reducing the achievable efficiency. The diode row is self-scanning at a frequency at least equal to the qotient of the material speed and image length in the direction of motion. the scanned periodically repeated signals are evaluated in a circuit consisting of a clocked memory, esp. a parallel shift register connected to an analysis circuit. A minimum resolvable digital increment is added to the register output as a result of the signal analysis.

Title: Leakage positioning in concrete encased pipework - is determined by detecting freon gas permeating concrete from pipe leak
Inventor: LARSSON BERTIL
IPC: F17D5/02
Filed: 1979-05-17
Abstract: Certain parts of building water supply and heating system piping are often encased in concrete whose thickness varies considerably. The position of a leak is determined by the detection of Freon gas introduced into the system and which rapidly permeates through the concrete. A water pipe system encased in concrete is emptied and refilled with air or water into which difluorodichloromethane or sulphurhexafluoride has been introduced to dissolve in the water. The mixt. passes into suspected faulty pipework and any leakage is detected by gas detector since the gas generated passes rapidly through the concrete.

Title: Microswitch under guitar string connected to electronic organ - enables player to play either instrument or both together
Inventor: NEUMAYER KARLHEINZ
IPC: G10H3/18
Filed: 1979-06-16
Abstract: In addition to pick-ups under the strings (24), an electric guitar has microswitches (27) inside the neck (18), with buttons (26) which protrude through openings (25) in the finger board (20) between the frets (19). The guitar is mounted on a stand. The pick-ups and microswitches are connected, via a control panel attached to the stand, to a nearby electronic organ. The pick-up outputs are amplified by the organ circuits and reproduced over its loudspeaker. The microswitches control corresp. notes on the organ and the control panel selects stops and registers. Thus a player can play the guitar by itself; the organ by itself, by fingering the guitar without striking the strings; or both together.

Title: Optical signal communication along transmission line - converts constant and alternating components into electrical parameters
Inventor: DELOACH JUN BERNARD COLLINS
IPC: H04B10/54
Filed: 1979-06-19
Abstract: In the communication system, the information is transmitted in the form of an optical signal along an optical transmission line. There is a detector which converts the optical signal into an electrial signal. The electrical signal is then fed through a processing circuit. The optical transmission line transmists an optical signal with a constant component and an alternationg component. The constant component, when converted, will be sufficient to supply the electrical equipment. The two converted components are passed through a filter, where they are sepd. and processed.

Title: PMMA roof fixture - by spring loaded tensioning strips allowing for thermal expansion and contraction
Inventor: SUKOW KLAUS
IPC: E04D13/03
Filed: 1979-08-08
Abstract: Arched roofs for use as shelters on bus stops, house doors, bicycle stands and pavements, specially those made of curved plexiglass panels, support the panels on curved hoops which are held in U-shaped strips, attached to the gutters along both sides. These strips allow for adequate expansion of the plexiglass panels which are held down on them by tensioning straps over the roof. The straps are hooked at one gutter to a barb on the shaped strip and at the other gutter to a tension spring. This prevents the deformation and damage to plexiglass by thermal stresses, esp. in case of strong solar radiation.
