Title: Dispensing pipette has calibrated bore and piston - with stroke adjustment device to vary dispensed volume
Inventor: EBERLE GUENTER
IPC: B01L3/02
Filed: 1980-07-08
Abstract: Dispensing pipette for accurate, predetermined quantities of liquid comprises a casing, with piston sliding in it; at the forward end of the casing the piston slides in a calibrated bore, the axial stroke of the piston being adjustable in order to obtain the desired dispensed quantity by means of an adjusting device. A preferred adjusting device consists of an arm rotatably mounted on the piston so that by rotation in one direction it is locked to the piston, whereas rotation in the opposite direction releases it from the piston. The bottom face of an externally actuated button bears against this arm. The adjustment travel of the piston is then limited by various stops for different strokes of the actuating button. These stops are distributed radially around the periphery of a revolving disc mounted on the housing and the stops are of different axial lengths; they are mounted beneath the arm to limit its pivotal movement. Instead of osing the tip of the casing for accurate dispensing, the forward end of the cylinder and piston itself serve this purpose. Thus the tip can be a cheap, throwaway tip.

Title: Dressing seams at welded window frame corners - in which spring-mounted cutters with lead in faces cleanly dress inaccurate frame surfaces
Inventor: GLOECKNER EBERHARD
IPC: B29C37/04
Filed: 1980-09-29
Abstract: Weld seams, at corner joints in window and door frames made of mitred thermoplastic profiled sections, are dressed off using at least one pressurised cutting tool moving along the weld, gripping the frame under pressure and applying cutters above and below the frame. Each cutter is applied to the frame under spring pressure at the outer corner, its leading face has a lead-in surface; during cutting action this lead-in moves along the side of the frame; each cutting edge is offset from the starting angle of the lead-in so that the cutters only act on the weld seam when they are aligned at the correct position. Low cost method, produce clean weld surfaces even if the outside faces of the frame are not accurately vertical or parallel.

Title: Dobby shaft drive - which has spherical gearing eccentrically on loom drive shaft
Inventor: OZGA HORST
IPC: D03C13/00
Filed: 1980-10-07
Abstract: A cog-free spherical gearing is coupled eccentrically to the drive shaft to convert the shaft rotation into a reciprocating rotation in an intermediate shaft, which is physically displaced, rocking through 90 deg. The forwards and backwards rotation amplitude ranges from zero, where the eccentricity of the coupling is zero, increasing proportionally with increased eccentricity. The angular speed function of the intermediate shaft is adjustable according to the eccentricity of the coupling, to reach zero twice in a defined zone on a 360 deg. rotation of the main shaft. A parallel rocking lever assembly carries the reciprocating rotation of the intermediate shaft to a drive shaft carrying the draw blade or beam drive lever in a ratio giving a constant value amplitude. The layout gives a drive transmission without free play, giving major force for the positive and negative accelerations required for the moving mass, in a low noise operation, with little wear for stoppage-free working.

Title: Boiler combustion gas heat-recovery method - uses granulate filling in combined heat exchanger and water-vapour absorber
Inventor: KRAEMER WILHELM
IPC: F24H1/50
Filed: 1980-11-03
Abstract: The method recovers heat from the still hot combustion gases, particularly of an oil or gas-fired central-heating boiler, using a regenerative absorbent heat-exchanger (3,4,5). The heat content of the gases above the return temp. from the heating circuit is extracted, together with the latent heat of the bulk of the steam content of the gases. The heat-exchanger (3,4) and a water-vapour absorber are combined into a unit connected after the boiler. The large surface area of the granulate filling (5) receives the heat contained in the gases and stores it. When the burner is off it is returned to the return from the heating circuit, thus drying the gases and lowering their dew point to appreciably below the circuit return temp.

Patent DE-3048322-A1 (DE)
Inventor: PFISTER JOSEF DIPL ING
IPC: B41B21/32
Filed: 1980-12-17
Abstract: The conveying path, which is determined by a supporting surface (2), of the tape-like photographic recording medium (1) is bounded on one side by a guide (3) for one lateral edge (1b) of the recording medium (1). A friction wheel (4), which has the shape of a truncated cone, is arranged in the region of this guide (3) and the guide-side edge region of the recording medium (1) runs over the said friction wheel (4). A pressing roller (7), which also has the shape of a truncated cone, is arranged opposite the friction wheel (4) with respect to the recording medium (1). The said pressing roller (7) presses the edge of the recording medium (1) against the friction wheel (4). Independently of the direction of transport, the moving recording medium (1) follows the larger diameter of the friction wheel (4) and therefore moves towards the guide (3). This ensures that one lateral edge (1b) of the recording medium (1) is constantly contiguous to the guide (3) and that the recording medium (1) therefore remains in position during transport. The lateral edge (1b) guided through the guide (3) therefore always adopts the same position, independently of the width of the recording medium (1). Recording media (1) of very different widths can be transported in this fashion in opposite directions, with precise lateral guiding and no conversion being necessary. <IMAGE>

Title: Device for determining the mechanical deformation behaviour of paints and varnishes
Inventor: JAECKEL KLAUS-PETER DIPL CHEM
IPC: G01N3/20
Filed: 1981-05-15
Abstract: In this device, two holding devices (3, 4) are mounted on a base plate (1) and the holding device (4), which essentially comprises clamping elements (8 and 9), is attached to a profiled rod (2) mounted vertically on the base plate. The profiled rod passes through the base plate and supports on its free end a drive wheel (5) which is mechanically linked to the holding device (3) which can be moved over a circular path. To determine the mechanical deformation behaviour of paints and varnishes, in particular of paint and varnish coatings on mouldings, a panel-type specimen (10) is clamped between the holding devices (3 and 4) and bent around the profiled rod (2) with the spacing of the holding devices kept essentially constant until crack formation can be detected in the paint or varnish layer at the point of bending. The angle traversed by the specimen (10) or by the holding device (3) on the base plate (1) during this process is a measure of the elasticity of the paint or varnish coating. <IMAGE>

Patent DE-3120900-A1 (DE)
Title: Microwave operating space
Inventor: FRITZ KARL DR
IPC: H05B6/72
Filed: 1981-05-26
Abstract: Until now, efforts have been directed at achieving a uniform energy distribution in the microwave operating space, averaged with respect to time, in order to achieve homogeneous heating of an object. This is adequate for relatively small objects but not, for example, for deep-frozen chickens or gateaux. In this case, an energy concentration at the centre of the object is essential so that, together with the necessary adsorption, there is a uniform (or even increased at the centre) energy level per cm<3>. This is achieved, however, only according to the invention, by means of interference of coherent or incoherent radiation from at least two radiation sources, the coherent radiations producing higher maxima and minima and providing greater capabilities for the distribution of the energy. This all takes place exclusively in the primary beam, that is to say the interference must be completed before the radiation can be reflected on the wall parts and hence lead to undefined phases and polarisation directions. If necessary, as normal, rotary or linear movements of the object are carried out. Typical examples are shown of these advances.

Title: Coffee grinder
Inventor: EISEL KARL
IPC: A47J42/06
Filed: 1981-10-26
Abstract: The invention relates to a coffee grinder with a grinding gear and arranged above this a storage container, from which coffee beans are conveyed into the grinding gear. In this connection, there is the problem that, for processing different bean sorts, e.g. normal and decaffeinated coffee beans, the storage container of the coffee grinder must in each case be refilled. In order to be able to grind two or more bean sorts alternatively or in an adjustable mixture ratio without refilling the bean stock, it is proposed to design at least two separate storage chambers (262, 264) in the storage container (234), which are in each case connected to the grinding gear (212; 302) by a connection duct (280, 282; 312, 314), and to provide them with a closure device (270, 272, 274; 306, 308, 316, 322, 324) which blocks to a greater or lesser extent the passage openings (318, 320) of the connection ducts. <IMAGE>
