Patent DE-3811585-A1 (DE)
Inventor: RIKER RUDOLF ING GRAD
IPC: E21D11/10
Filed: 1988-04-07
Abstract: Concrete is pumped through a delivery line (16) into an annular distribution line (30) which has branch lines (34) at circumferential distances apart. The branch lines (34) can be blocked individually by means of shut-off members (36). The other end of the distribution line (30) is attached to a concrete-discharge device (52). When the latter is actuated, the concrete located in the distribution line (30) is emptied over part of the delivery line (16) into a collecting container (82). The emptying operation can be started automatically before the concrete sets in the piping system.

Title: Connecting member for profile bars
Inventor: BAER WALTER
IPC: F16B7/04
Filed: 1988-09-19
Abstract: The intention is to provide a novel connecting method in the case of a modular construction system with profile bars (2, 12) which have essentially a rectangular cross-section and exhibit axial T-grooves (5, 5') for T-head bolts (8) on at least two delimiting sides (7, 7') of the cross-section. The intention is for it to be possible to add on profile bars (12), in particular, even in the case of T-grooves (5') in which plug-in walls (3, 4) are arranged. For this purpose, two claws (11) of a connecting member (10) are made to engage into in each case one T-groove (5') of two abutting delimiting sides (7, 7') of the first profile bar (2). These two claws (11) are clamped in a frictionally locking manner by a bracing device (14, 15). The connecting member (10) is provided with devices for adding on at least one further profile bar (12). <IMAGE>
Patent DE-3833104-A1 (DE)
Title: Beam-guiding element
Inventor: BAIER ERICH
IPC: G02B6/00
Filed: 1988-09-29
Abstract: In a beam-guiding element which is suitable for colour densitometers, the measuring beam (test beam, sample beam) entering via a small diaphragm opening (aperture) is split by a three-part prism into three partial beams which are guided outwardly in the shape of a star and are then again deflected parallel to their entry direction so that they leave the beam-guiding element at a substantially larger mutual distance than when they entered. As a result, the light-sensitive elements used for measuring the three primary colours can be arranged at constructively convenient distances from each other and with their requirements in terms of assembly do not limit the diameter of the measuring beam so that point-shaped light measurements are possible. <IMAGE>

Title: Stunning station for slaughterhouses
Inventor: KRAUCH OTTO
IPC: A22B1/00
Filed: 1988-11-30
Abstract: A stunning station for slaughterhouses, having an enclosed area (6) for receiving a plurality of unstunned animals to be slaughtered, especially pigs, and having a collecting trough (30), which is arranged at the edge of the area (6), for collecting a stunned animal to be slaughtered is characterised in that the enclosed area (6) is essentially bounded, if desired with the exception of the collecting trough (30), by walls which are rounded in horizontal projection, and in that a displacement body (12) is arranged essentially in the centre of the area (6), an essentially annular passage for the animals to be slaughtered being formed between the outer wall of the said body (12) and the wall of the area (6). This means that force does not have to be used to drive the animals to be slaughtered, and so stress-induced impairment of the quality of the meat can be avoided. <IMAGE>

Title: Exposed sample testing corrosive effect of flowing gas - is maintained at specific temp. related to adjacent measured dew point
Inventor: EBEL PETER DIPL PHYS
IPC: G01N17/00
Filed: 1989-05-03
Abstract: A disc of material (5) is exposed in a conduit (1) to a stream of flowing gas, e.g. waste gas from an industiral process whose corrosive effect on the material is to be tested. The disc is at the end of a tubular holder (4), projecting outside the conduit and receiving a continuous circulation of a tapering medium. This medium is held at a temp. slightly above or below, by a specified difference, that of the dew print for the flowing gas, as measured by a standard device (2) closely adjacent the test-disc holder. The disc, whose underside carries a temp. sensor (6), is periodically examined to establish the nature and extent of any corrosion. The required tempering temp. of the circulating liq. or gas is produced by a heat exchanger (7) subject to a controller (9) supplied with data on dew pt. and reqd. difference for test-dsic. ADVANTAGE - Since temp., pressure and compsn. of gas stream may greatly vary, more significant results are obtd. by in-situ testing.

Title: Quick clamping device for wishbone boom of sailboard - has lever to pull clamp tightly around mast via two half shells
Inventor: FELSBERG JUERGEN
IPC: B63B35/79

Title: Automatic quality control in granules - system tests samples and diverts material outside tolerance to separate containers and mixes it with fresh material
Inventor: REIMELT WOLFRAM DIPL ING
IPC: B29B9/06
Filed: 1989-07-14
Abstract: Granules, made up of different proportions of various component materials, are produced to a constant make-up to set tolerances by feeding the individual components through a weighing out holder and centrally controlled metering dispenser to an extruder and from there to a granulating device.  The properties or particular features which are required in the granules are measured continuously and the results are fed to a computer so as to determine the values needed for regulating the quantities of the components used; when the values deviate from the nominal by a set degree the granules are collected separately, measured in quantity, and their deviant values are recorded; the granules concerned are then fed in to the extruder parallel to the primary materials, via the weighing out holder and metering dispenser and under the control of the computer. ADVANTAGE - The procedure completely eliminates the production of second grade output from granules deviating from tolerance limits, such as the granules made when starting up the extruder or during some abnormal phase of production.

IPC: G07F1/04
Filed: 1989-09-07
Abstract: A coin selector has an input opening means including two walls (7, 8), one of which (8) is pivotally mounted (9). The walls converge and rest against each other in a closed position. insertion of a coin (11) between the walls forces the walls apart whereafter they close again after the coin has passed. Two photodiodes (13) are provided facing each other. An arm (15) is fixed to the pivotable wall (8) and extends between the photodiodes. The arm has an aperture (16) in alignment with the photodiodes when the walls are in the closed position. The arm interrupts the beam when the pivotable wall pivots away from the other wall. The selector has electronic means which is activated each time the aperture of the arm is aligned with the photodiodes following interruption of the beam by the arm. If a wire (12) is attached to the coin, this will maintain the arm (15) in a position in which the beam is interrupted and the electronic means will not be activated. <IMAGE>
