Title: Internally sited movable window heat insulation - comprises rail guided panel sunk into recess, movable manually or automatically for closure
Inventor: URBANEK AXEL
IPC: E06B9/04
Filed: 1979-12-21
Abstract: Provision is made for guiding a heat-insulation unit in a running-rail, joined to the window case, so that it disappears when the window is opened, and can be closed when necessary or in emergency with a handle or by automatic control. A panel of insulating material, 5-8 cm-thick, is sunk into the wall, from the window recess, upwards and downwards, and possibly sideways. When required this can be thrust in front of the window, with a handle, or automatically. A metal or plastic rail can be mounted partly outside the wall, to save space. The insulation is completely protected from weather and damage from outside, and is easily handled indoors.

Title: Carburettor with automatic choke - superimposes pressure between choke and throttle on pressure-dependent setting device
Inventor: SIEBLER JOHANN ING GRAD
IPC: F02M1/10
Filed: 1980-02-08
Abstract: The carburettor with automatic choke is particularly for automotive IC engines. It has an intake passage controlled by a main throttle, upstream of which is Venturi with a fuel-supply system, together with a choke butterfly. When the engine is cold, the choke butterfly is pre-loaded shut by a temp.-sensitive setting device, and on starting it is opened for a predetermined amount by a second time-lagged setting device dependent on the pressure downstream of the main throttle. The pressure or vacuum in the intake passage between the choke butterfly and the main throttle is superimposed on the pressure-dependent setting device.

Title: Insulating panel for inner face of external wall - is esp. of polystyrene with full ventilation in channels on rear face
Inventor: HIRSCH ULRICH
IPC: E04F13/00
Filed: 1980-05-07
Abstract: An insulating panel for fitting to the inner face of external walls of buildings provides full ventilation behind it; the rear face of the panel possesses, at specific intervals, projections in the form of studs or ribs and corner reinforcement. These bear against the wall, thus leaving ventilating panels between them. The projections may be round, square, rectangular, undulating or zig zag shaped. In particular the projections are 20-30 mm in height. Preferred material for the panel is polystyrene. The conventional brickwork or concrete of the wall has full ventilation on the inner face and problems over long periods as a result of the hermetically sealing effect of the panel are eliminated.
Patent DE-3022812-A1 (DE)
Title: Air leakage into insulating gas in sealed container - observed as colour change in chemically reduced redox indicator
Inventor: HOLLMANN FRITZ
IPC: H02B13/065
Filed: 1980-06-19
Abstract: Leakage of air into a sealed container for electrical equipment such as switch-gear and which is filled with an insulating gas is visually observed through the transparent wall of a display element and appears as a colour change. This change occurs in material such as blotting paper treated with a redox indicator, initially reduced to the colourless state but becoming coloured if oxidised by air leaking into the container. The display unit after prepn. e.g. in a gloove-box is attached to the electrical unit, e.g. by a screwed connector sealed with a pluq which is then removed to bring the element into contact with the container atmos. For containers filled e.g. with sulphur hexafluoride at ambient pressure. The element is cheaper, easier to transport and occupies less space than known gas balances used for the same purpose.
Patent DE-3025665-A1 (DE)
Title: Workpiece feeder slide for friction welding machine - where slide includes rotary turret carrying two workpiece clamping chucks to increase productivity
Inventor: DORNHEIM GUENTER
IPC: B23K20/12
Filed: 1980-07-07
Abstract: The slide housing includes a journal on which a turret can rotate; and tow or more chucks in which a workpiece is clamped are located in a circular row on the turret. The turret is fitted with a slotted disk and a gearwheel meshing with gears used to rotate the turret stepwise. When each chuck reaches the welding axis, a centering bolt on the slide enters a hole in the turret to ensure that the chuck axis coincides exactly with the welding axis. In automatic welding using two chucks, the next workpiece can be placed in one chuck while the previous workpiece is being welded, so the effective cycle time is reduced.

Patent DE-3046853-A1 (DE)
Title: Maintaining constant torque on rotary rabble in tank - for settling solids from suspension
Inventor: SCHUECKER FRANZ-JOSEF
IPC: B01D21/06
Filed: 1980-12-12
Abstract: The deposited sediment layer in a settling tank for suspensions is kept moving by a rotatably driven rabble. When the resistance to the stirring effect increases, the rabble is at least partly raised from the tank base and returned when resistance becomes normal. The raising is effected by a transmission member between the rabble and its drive unit which resolves the drive torque into a horizontal component (for rotation) and a vertical component (for lift). The transmission member may have a threaded spindle engaged inside a central threaded boss, or a pair of hydraulic piston units whose pressurised chambers are interconnected. The system does not require the hydraulic drive unit with its controls as used in similar known devices. The resistance of the solids layer to the stirrer and hence the drive torque needed are kept constant.

Title: Device for measuring the mass flow of a flowing medium, in particular for measuring the mass flow of fuel fed to combustion engines
Inventor: SAUTTER WILFRIED
IPC: G01F1/684
Filed: 1981-04-18
Abstract: A device for measuring the mass flow of a flowing medium is proposed, which has a measurement zone (26) which is located in a flow channel (23) and has at least two gaps (27, 28) running in the flow direction of the medium. The delimiting wall of at least one gap (27) is formed by a carrier (31) on which a hot-layer resistance layer (3) is applied, whose temperature and/or resistance are controlled in dependence on the mass flow of the medium and the control variable is a measure of the mass flow of the flowing medium. On that surface of the carrier (31) facing away from the hot-layer resistance layer (3), a further resistance layer (4) of the bridge circuit may be provided. Further layer resistors of the bridge circuit may be arranged on further carriers (32, 33). A calming zone (36) upstream of the measurement zone (26) serves for calming the medium flow. The device according to the invention ensures stable conditions for exact measurements over a very wide measurement range. <IMAGE>

Patent DE-3118775-A1 (DE)
Title: Labelling station of a labelling machine for articles, such as bottles
IPC: B65C9/46
Filed: 1981-05-13
Abstract: The invention relates to a labelling station which makes it possible to mark the labels. To transfer labels from a fixed label stack onto a gripper cylinder, at least one extraction element is mounted on a rotating carrier so as to be rotatable or pivotable between its cylindrically curved receiving surface and its centre of curvature. As a result of this geometry and of the cam-controlled rotational or pivoting movement of the extraction element, it is possible for the extraction element to roll both on the essentially plane front side of the label stack and on the rotating gripper cylinder and a rotating glue roller. A marking element arranged on the carrier serves for marking and is likewise driven non-uniformly about its own axis. The marking-type field rolls on the label held by the extraction element. For inking the marking-type field, there is an inking roller which is arranged on the outer periphery of the carrier between the label stack and the gripper cylinder and of which the outer casing is concavely profiled and the axis of rotation is perpendicular to the axis of rotation of the marking element. The marking-type field rolls in a virtually slip-free manner on this inking roller which is stationary during the inking.

Title: Microwave amplifier
Inventor: KLEIN GERALD
IPC: H03F3/21
Filed: 1981-05-12
Abstract: In a microwave amplifier, an inbuilt test point circuit is located at the location of each individual amplifier stage for measuring the performance capacity of the individual amplifier stages with respect to one another. The individual amplifier stages (A1, A2 ... An) operate in parallel, responding to a common RF input signal in order to combine their power gain and to output a composite RF power output signal. The individual amplifier stages are supplied with DC bias power from a common bias supply circuit via in each case corresponding bias supply lines, each bias supply line (L1, L2 ... Ln) exhibiting an RF bias filter circuit. In a preferred embodiment, a piece of wire (46) which is connected to a corresponding section of the respective supply line is provided for each bias supply line. Each piece of wire (46) can be connected with one end to earth whilst its other end (50) can be connected to a measuring instrument. Around a section of the corresponding bias supply line and a section of the piece of wire, an annular ferrite pearl is arranged in order to couple a voltage signal, which represents a function of the changing current in the bias supply line, magnetically into the piece of wire. The voltage signals magnetically coupled in form a measurement variable of the relative performance capacity of the individual amplifier stages with respect to one another. <IMAGE>

Title: Mounting system for facing-masonrywork elements
Inventor: WOEBKE KLAUS
IPC: E04F13/08
Filed: 1981-07-17
Abstract: The facing-masonrywork elements or frost-resistant-masonrywork elements are prefabricated in dimensional-grid templates, i.e. are assembled from individual blocks to form elements, and, reinforced with a carrier/suspension mounting rail, are simultaneously provided with mortar and jointed. The finished elements are suspended, along with the carrier/suspension mounting rail, in a grid rail fitted perpendicularly on the building wall and are pushed into the assembly. Only the joints of the elements still have to be provided with mortar and jointed on the building site. It is thus possible to produce the elements at the factory. Mounting of the elements thus saves a lot of time and is also suitable for existing houses and facades for the purpose of subsequent heat insulation and sound insulation and also for renovation, the fitting of ventilated facing-masonrywork facades on the front of new buildings and existing buildings being possible in a time-saving and cost-saving manner.
Patent DE-3128569-A1 (DE)
Title: Batching and mixing plant for road-building material
Inventor: NIEMANN DIETRICH WARNKE
IPC: B28C9/04
Filed: 1981-07-18
Abstract: In areas in which there are no natural rock deposits for producing the substructure of roads, the road substructure is produced from a stabilising layer of sand and cement. This production of the stabilisation at the building site has various disadvantages. The invention proposes a plant in which all the units are arranged on, preferably two, transport vehicles, the arrangement being such that, with the transport vehicles placed behind or next to one another, the conveying devices for the raw material run from the one transport vehicle to the other transport vehicle. This mobile plant is set up in the region of a gravel pit closest to the road building site, the advantage being that the cement/sand/gravel mixture is produced at the gravel pit, so that the transport of the stabilising material to the building site is less expensive and the application of the stabilising layer at the building site is made easier.
