Title: Non-cylindrical container for card sliver for spinning machine - allowing easy replacement and continuous inspection of sliver level
Inventor: LANGHEINRICH DIETER
IPC: B65H75/16
Filed: 1975-04-19
Abstract: Container for card sliver for spinning machine is of non-circular cross-section, pref. oval cross-section. Pref. the side walls of the container are flat surfaces, and the relationship between the width of the individual container and the position of the spinning point can be adjusted to allow each container or two adjacent containers to be associated with one spinning point. This arrangement allows the empty space between containers to be reduced. As the sliver when placed in the container runs off a reel with a circular motion, the container is reciprocated in its longitudinal direction during filling, whereas conventional cylindrical containers are rotated during filling. Only small changes are required to fill the containers in existing filling stations.

Title: Automatic weighing out device - intermediate conveyor provides gentler handling for goods liable to damage or deforming
Inventor: EISTETTER RUDOLF
IPC: G01G13/08
Filed: 1975-06-16
Abstract: An automatic weigher is for the continuous checking of goods fed by a conveyor. A pair of weighers operate in push-pull fashion to control fillers in advance of them with coarse and fine dosing provisions. Each coarse filler (19,20) is preceded by a pivoted intermediate conveyor (9) with discharge end (17) extending over the inlet end (18) of the fine filling device, which is arranged to swing between the input ends of the two coarse conveyors (19,20). The system prevents rough handling of the goods, and is suitable for weighing out prepackaged bakery products or other goods liable to damage.

Title: Filament section of volume measuring system - is used on textile machines with continuously accurate measurement of asymmetrical portions
Inventor: THELEN PAUL
IPC: G01B11/10
Filed: 1975-07-18
Abstract: A measuring system for the cross-section or volume of a moving filament in a textile machine can cope with asymmetrical cross-sections or volumes with continuously adequate accuracy. The measurement is effected photo-electrically alternately in different directions by means of at least two measuring channels (K1, K2). A switching system ensures that only one channel generates a signal at any given time and that only the light source assigned to the signal-generating channel is energized. The filament may be measured by analysing shadow images.

Title: Proportioning and shut off valve for battery water mixing - has axially movable rotary spindle with eccentric extension and port sealing sleeve
Inventor: HUMPERT JUERGEN
IPC: F16K11/02
Filed: 1975-07-19
Abstract: The battery housing (1) has inlets (2) for warm and cold water on opposite sides of the cylindrical casing. There is a controlling shut-off valve which moves in the cylinder, and consists of a guide sleeve pressed against the sealing sleeve (6). A piston with an eccentric extension (13) can rotate inside the guide and sealing sleeves. The sealing sleeve is retained by a projection (9) which fits in an axial groove (10) in a connecting rod (11) spanning the sealing sleeve. The lower end of the eccentric piston extension (13) curves outwards towards the spindle end. Both openings (2) may be closed by pulling the spindle so that the wider end pressed the seal against the openings, or either may be selectively opened by rotating the eccentric section (13).

Title: Fluidised bed unit with adjustable solids offtake - in the form of telescopic sliding tube
Inventor: STEINBERG WERNER ING GRAD
IPC: B01J8/00
Filed: 1975-08-02
Abstract: The wall of the fluidised bed unit carries an off-take nozzle within which is a sliding tube which can move axially and so determine the bed height. This sliding tube also moves within the fixed solids offtake duct which is external to the fluidised bed. Used in systems for handling, reacting or drying solids, in which it is advantageous to vary the bed height according to the characteristics of the material being processed. Ability to vary the bed height enables optimum operation to be obtd. with a variety of solids, and the use of an adjustable solids offtake which has no internal restriction in it avoids any possibility of blockage.

Patent DE-2540418-A1 (DE)
Inventor: HILBER JOHANN
IPC: B60K11/06
Filed: 1975-09-11
Abstract: Elongated, comb-like damping elements (5) are inserted between the cylinder cooling fins (4) of a slipstream-cooled internal combustion engine. Together these produce a closed wall surface, which reduces the radiated noise of the engine. At the same time they form, together with the external cylinder surface (11) closed cooling air ducts (12), which lie in the direction of travel and consequently ensure optimum cooling of the engine. <IMAGE>

Title: Large size flange forming method - forms rectangular cross section primary ring and forms final shape in several operations
IPC: B21H1/06
Filed: 1975-09-12
Abstract: A flange is made from a blank cut from cylindrical bar from a furnace. The blank is then forged to a height which corresponds to the overall height of the finished flange. The blank is then punched to produce a through hole. A subsequent rolling produces a ring shape with the inner diameter of the ring corresponding with the inner diameter of the finished flange. The annular cross section is about half of the width of the finished flange. A final forging operation produces the required flange shape followed by a machining operation.

Title: Air cooled IC engine with additional cooling facilities - taking air from oil cooler to charge cooler or heater
Inventor: THOLEN PAUL DIPL ING
IPC: F01P11/08
Filed: 1976-02-03
Abstract: The air-cooled IC engine with additional cooling facilities is basically a conventional in-line engine with a ducted fan at one end and an oil cooler cooled by air from the fan along-side the cylinder block at the other end. The engine has an exchaust-driven turbo-charger. An additional heat exchanger for the air from the turbo charger is fitted above the flywheel supplied with air that has passed through the oil cooler so that the combustion air can be cooled or heated as ambient conditions require. Air flow quantity can also be regulated. A flat cooler on top of the cooling air duct makes further use of the fan capacity. This cooler can serve the hydraulic transmission or a driven machine, or can supplement the main oil cooler.

Title: Coin checking unit for coin-operated machine - has sensors in gravity feed inlet section coupled into comparison circuits checking validity of coins
Inventor: KOCH KARL-JUERGEN ING GRAD
IPC: G01N27/72
Filed: 1976-08-17
Abstract: The inlet channel of a coin operated unit has a number of sensors to check the relevent characteristics, e.g. weight, material, size etc. The system is designed to allow an accurate check to be made while the coins are in motion. In a gravity feed section are located three separate sensors of different sizes that are triggered by coin passage.

Title: Shuttle thread tension measuring system - regulates friction of leaf spring on shuttle against thread
Inventor: GLAETTLI MAX
IPC: B65H59/00
Filed: 1976-08-27
Abstract: The system measures and regulates the thread tension at the shuttle of an embroidering, stitching or sewing machine. The thread is extracted by friction from the shuttle and is loaded by an adjustable leaf spring on it, and the tension is measured by a force acting on the thread at right angles to its travel direction. The return force exerted by the thread represents the actual tension, which is compared with a desired value. During rectification the thread tension is continuously measured and the discrepancy between actual and desired values is used to regulate the frictional force exerted by the leaf spring on the thread.

Title: Concrete anchoring for tubular hand rail or step - has tube driven on to flat wedge and resilient plug previously positioned in hole drilled in concrete
Inventor: FISCHER ARTUR DR
IPC: F16B13/08
Filed: 1976-10-23
Abstract: The anchoring method serves for fixing hand rails and steps or similar elements into concrete. To install the step (1) into a hole drilled into concrete wall (4) the pipe end (2) is slid into the hole and then driven against flat wedge (5) placed in advanced into the hole together with elastic plug (7). The smallest width of the wedge corresponds with the inside diameter of the pipe and when the pipe end is driven against the wedge it deforms into an elliptical shape providing with its great axis a secure anchoring on the internal wall surfaces of the hole. The plug (7) serves as a guide for the wedge to prevent it turning as well as providing a vibration-resistance fixing due to the slight deformation of the plug itself.
