Title: Circular knitter yarn feed - forms yarn loop of measured length for each needle held by suction on perforated support plate
IPC: D04B9/02
Filed: 1976-04-12
Abstract: The mechanism to measure the length of yarn to each needle of a circular knitter, by forming a loop in the yarn before knitting, uses a support of a perforated material for the yarn loop to lie on its upper surface and be held in place by suction. Pref. the yarn loop support is a mesh or a drilled place with a suction channel leading to its reverse side, forming a funnel-shaped unit. The funnel cross section tapers away from the loop support plate. The system ensures that the required length of yarn is prepd. for the needle, before knitting, and held in the ready position without tension on the yarn.

Title: Ultrasonic proximity switch esp. for photocopiers - detects air blast noise by microphone to indicate paper position
Inventor: SCHAFFER DETLEF
IPC: G01B17/00
Filed: 1976-06-14
Abstract: The ultrasonic proximity switch esp. for photo-copying machines, may be used with all sizes and types of paper, including transparencies. The paper input feed rails and output guides have small apertures above and below the surface of the paper. The upper orifice is fed from a high-pressure air line so that a wide-band ultrasonic noise spectrum is established at the nozzle. An ultrasonic microphone in the vicinity of the lower aperture, detects the noise level depending on whether or not a sheet of paper is present. The output waveform of the microphone is integrated and this signal is amplified for further use in the switching functions of the machine. Any number of proximity detectors may be driven from a common air supply.

Title: Balanced unearthed interference free line for analogue signals - has high output resistance and low differential resistance and avoids need for transformers
Inventor: LEUNIG PETER
IPC: G01R17/06
Filed: 1976-10-30
Abstract: An electronic circuit is used for the transmission of analogue signals, esp. in studio and measuring technology on a balanced, non-earthed channel. It gives freedom from interference by inductive or capacitive pick-up and avoids the need for line and input and output transformers. Negative and/or positive feedback coupling is applied to ensure that the direct output resistance is greater by one or more orders of magnitude than the differential output resistance. The circuit is characterised by a low voltage source (UE) with resistance increased by direct coupling or a high resistance source with resistance reduced by differential feedback coupling.

Patent DE-2711545-A1 (DE)
Inventor: ECKER HANS
IPC: F28D7/16
Filed: 1977-03-17
Abstract: The heat exchanger can be used, e.g., as a steam generator or reheater in the primary coolant circuits of high-temperature reactors. In the case of relatively large units of such heat exchangers, the perforated plates at the ends of the straight tube bundles require a comparatively large amount of space, and earlier proposals for a more compact design could not provide satisfaction because of the difficulties bound up therewith. The solution now consists essentially in that each straight tube bundle (3) has on both sides intermediate distributors (14) or intermediate headers (15) which in each case combine a plurality of individual tubes and are arranged in different planes lying perpendicular to the axis of the heat exchanger so that adjacent intermediate distributors or intermediate headers are offset with respect to one another and can cover one another in plan view. As a result the perforated plates (12, 17) can be kept substantially smaller, avoiding the disadvantages of earlier proposals. <IMAGE>

Title: Combustion chamber for IC engine - has storage chamber separated from ignition chamber by poppet valve
Inventor: MOIROUX AUGUSTE
IPC: F02B21/00
Filed: 1977-03-30
Abstract: The cylinder head contains in addition to the conventional inlet and exhaust valves and combustion chamber, an ignition chamber (8) and a storage chamber (9). The two chambers are separated by a hydraulically operated poppett valve (12). The ignition chamber contains the fuel injector nozzle (14) and joins up with the combustion chamber by a restricted passage (27). The poppett valve opens as a result of compression from the main combustion chamber during compression stroke and is pushed onto its seat by hydraulic force (16) 20 degrees before piston top dead centre and released 30 degrees after top dead centre. The stored air is then able to mix with the combustion gases and reduce the toxic exhaust content.

Title: Roll prevention control for aircraft - has individually driven spoilers on outboard wings to compensate for failure of one engine
Inventor: ANTONOV OLEG KONSTANTINOVITSCH
IPC: B64C17/00
Filed: 1977-10-07
Abstract: The control operates to prevent the rolling of an aircraft having an even number of propulsion units, when one of the propulsion units stops operating due to a breakdown. Spoilers are mounted on the outboard wings. Each spoiler has an individual drive connected to a power circuit via a control valve which, in turn, is functionally associated with a failure detector of the propulsion unit disposed on the outboard wing opposite to that on which the respective spoiler is mounted. The apparatus is brought into action automatically, to counteract the rolling tendency of an aircraft when one of its propulsion units fails. A manual control can correct the glide path during landing, dissipating the lift and applying the aerodynamic braking during the landing roll.

Title: Pressure head type flowmeter with eddy current damping - has torsion arm carrying detector arm and paramagnetic plate moving between poles of magnet
Inventor: PAUL BERNT DIPL PHYS DR
IPC: G01F1/28
Filed: 1977-11-16
Abstract: The pressure head flowmeter comprises an inlet tube (4) through which the fluid medium flows (2) and a flange-mounted transducer head (6). This latter consists of a permanent magnet (11) with two field plates (14, 15). In the vicinity of the plates is a moving detector element (18) suspended in the bore of the tube by means of torsion spring arms (19, 20). Diametrically opposite the detector element is a vertical disc counterweight (25) of paramagnetic material which can move between the pole-pieces of a permanent magnet forming part of a damping mechanism. Each movement of the detector element produces an opposite movement in the damping disc which is affected by the braking force induced by eddy currents.

Title: Automatic control gear for burners of refractory-lined furnaces - uses thermostatic system to override photoelectric control
Inventor: GEHRMANN HEINZ
IPC: F23N5/08
Filed: 1977-11-29
Abstract: The automatic control equipment for burners heating a refractory-lined furnace, partic, a refuse incinerator after-burning chamber, uses a signal (6) from a temp. sensor (5) in the chamber (2). This operates an actual valve indicator (7) working in conjuction with a manually adjustable (9) desired valve unit (8). If the actual valve rises above the other, the circuit of a photoelectric flame monitor (10) is broken, causing closure of the oil supply valve (11) to the burner (3) and stopping of the pump (12). Reversal of this temp. relationship results in re-activation of the burner.
