Title: Carburettor for IC engine - has pump returning part of mixture from downstream to upstream of venturi
Inventor: FIALA ERNST PROF DR
IPC: F02M33/02
Filed: 1980-06-30
Abstract: The carburettor has a venturi (2) in the air intake with a throttle (3) downstream of it. Fuel is delivered through an orifice (6) from a float chamber (5) to a nozzle (4) in the venturi. Part of the resulting mixture is drawn off (9) downstream of the venturi and raised to a higher pressure by a pump (7) driven by a small electric motor. The pump delivery is returned into the carburetter suction. Part of the pump delivery is returned to the suction downstream (11) of the venturi and part upstream (10) of the venturi. This increases the flow through the venturi and results in better vapourisation at low engine loads.

Title: Frangible casing for filter in high tension appts. - bursts under vacuum applied before filling with insulating gas
Inventor: KERSTEN KLAUS-DIETER DIPL ING
IPC: H01F27/20
Filed: 1980-09-22
Abstract: High tension appts. which in use is filled with insulating gas contains a filter for adsorbing moisture present in the gas. The filter when first installed has an air-tight casing which bursts open when the appts. is evacuated prior to filling with the inert gas. The casing may be a metal or plastic foil, and this may constitute a frangible closure for a portion of the high tension appts. The closure may include a gas-permeable ceramic disc The absorptive capacity of the filter is not reduced by premature exposure to the moisture-contg. air present before the preliminary evacuation takes place, and the filter may therefore remain effective for many years.

Title: Process for collecting and safe disposal of gaseous sodium or potassium
Inventor: DOMAZER HANS-GUENTER DIPL ING
IPC: B01D53/42
Filed: 1981-01-08
Abstract: The invention relates to a process for collecting and safe disposal of gaseous sodium or potassium which have been liberated during metallothermal reactions, and is characterised in that the gaseous sodium or potassium is injected into a silicic acid xerogel bed which is sufficient for complete absorption. Preferably, the gaseous sodium or potassium is injected into approximately twice the amount, based on the weight of the sodium or potassium, of silicic acid xerogel which, in particular, has a particle size of approximately from 1 to 5 mm. The silicic acid xerogel obtained contains the sodium or potassium partly in free and partly in bound form, from approximately 25 to 75% of the alkali metal, depending on the moisture content and reactivity of the silicic acid xerogel, being present in the free form. For the purpose of safe disposal of the alkali metal, the silicic acid xerogel loaded with alkali metal can be stirred into an excess amount of water, the alkali metal slowly being converted in the process into the corresponding hydroxide.

Title: Driving, teaching and practising device
Inventor: SCHAELLING WERNER
IPC: G09B9/02
Filed: 1981-03-06
Abstract: The invention relates to a driving, teaching and practising device for teaching and learning how to hold the reins for one-horse and two-horse driving. It permits the simulation of all situations which occur in practise. It can furthermore be collapsed for improved transport in such a way that it can be transported in car boots. I consider this fact to be very important, as it allows the driving instructor to transport the device from one training location to another in a more pleasant fashion. The attached drawing (Figure 4) shows a side view of the device in the collapsed condition. The items (1/3) with accessories represent lines with auxiliary weights, and items (9/10) and (11/12) represent the telescopic tubes with locking device (item 6). Items (7/8) are to be seen as telescopic pipes in a transverse direction and a lateral view of them is shown in the attached drawing. The device can be extended to encompass "driving with more than one horse". <IMAGE>

Title: Measuring arrangement for the feed rate, the fed length and the weight of a fed length of a driven, elongated body, as well as for controlling its feed rate
Inventor: STRUNK HELMUT
IPC: G01P3/489
Filed: 1981-03-19
Abstract: A measuring arrangement for the feed rate, the fed length and/or the weight of a fed length and/or controlling the feed rates of an elongated, wire-, fibre- or band-like body which is fed or drawn forward between driven transport rollers bearing against it, in particular the welding wire for inert-gas-shielded welding devices, is to be constructed such that reliable, accurate measurements are rendered possible in conjunction with ease of reading-off, and in the case of the use of control devices for setting a constant feed a reliable actual value signal is delivered for these as well. In this case, the wire or fibre is guided in the measuring arrangement between an unloaded gauge roll and a pressure roll pressed against the latter, of which rolls one has at least one lateral shell made from metal and the other such a shell made from rubber, and there is connected to the gauge roll an electric pulse generator whose output signals are fed to an evaluation device which converts the signals into pulses which it counts and conditions, and also via display converters controls display devices representing the measured values visually, or feeds them as actual value to a control device which determines the rotational speed of the transport rollers of a drive device.

Title: Method and circuit arrangement for setting up conference connections between subscriber stations of a telecommunications network
Inventor: SPAETH GUENTHER ING GRAD
IPC: H04M3/56
Filed: 1982-06-19
Abstract: If conference connections are set up via a space-division multiplex switching network with integrated semiconductor switching points, stringent requirements for signal transmission in the space-division multiplex switching network must be met in the practical implementation. A loss-free conference connection between any number of subscriber stations with a return loss of more than 40 dB imposes a stringent requirement on conference circuits. For the purposes of meeting these requirements, signal transmission takes place in the space-division multiplex switching network by means of impressed currents, and each conferee's own signal component is subtracted from the composite signal of all conferees.
