Inventor: THORWIRTH GUENTER DR
IPC: H04N5/30
Filed: 1989-08-04
Abstract: The camera includes an optical filter arrangement 2 comprising a colour fitter unit 21 and/or a rotatable linear polariser 22 inserted into the imaging optical train in front of a rapid image converter 3, which is also part of the evaluating optical train. A driving unit 11 co-ordinates the combined interconnection of the switching states of both the filter arrangement and an adjustable diaphragm arrangements (in the form of a liquid crystal), and as a result, measured values which involve multiple characteristics can be evaluated with an evaluation unit 12 similar to that applied during exclusive zone-sampling analysis. The arrangement has applications in the field of microscopy, and in industrial robot technology may be embodied as an optical sensor. In the building and construction industry it has uses in differentiating and classifying a variety of elements such as electronic components and optically detectable conditions. <IMAGE>

Title: Syringe with spring-loaded cannula - which is fully retracted after first use of syringe to prevent reuse
IPC: A61M5/32
Filed: 1989-08-04
Abstract: The syringe, for once only use, has a cannula (3) attached to a cylindrical body (1) in which a piston (8) operates. The piston (8) has a piston rod (6) which forms the actuating handle of the syringe. The length of the cannula (3) is such that it can be fully retracted within the cylindrical body (1). A spring (15) inside the body (1) exerts a force on the cannula (3) tending to retract it. A stop (18) holds the cannula (3) in the extended position. When the syringe is used, the piston (8) is pressed to its lowest position and a rod (20) inside the piston rod (6) is pressed against the stop (18) and breaks it up so that the spring (15) is released and the cannula (3) is retracted. The stop (18) is made of a brittle material which is easily broken. USE/ADVANTAGE - The retraction of the cannula prevents re-use of the syringe.

Title: Piston type IC engine - has cylinder axis offset from crankshaft axis
Inventor: HAEBERLE UWE
IPC: F02B41/04
Filed: 1989-12-21
Abstract: A piston type internal combustion engine with at least one cylinder and one piston has the cylinder equipped with inlet and outlet valves and has a fuel supply or fuel injection system. The cylinder is positioned w.r.t. the crankshaft axis so that the line of action of the piston is offset from the crankshaft axis. This asymmetric arrangement of the piston and cylinder results in a slower suction stroke with a better filling of the cylinder.  A faster compression stroke reduces the loss of the heat of compression to the cylinder walls. A slower working stroke results in a longer working time for the hot gases to act on the piston and a faster exhaust stroke reduces the heat transfer to the cylinder walls. USE - Internal combustion engines.

Title: Cross wound bobbin winding - uses selected opening and final valves for yarn crossing angle and winding ratio from initial wound layer to last layer
Inventor: BROCKMANNS KARL-JOSEF DR ING
IPC: B65H54/28
Filed: 1990-07-31
Abstract: While winding a cross wound bobbin, where the bobbin is rotated while the yarn is laid by a reciprocating yarn guide, the laid yarn crossing angle is steadily changed according to the bobbin dia., at least near to a steady change, from an opening value for the initial wound layer to a final value at the end of the last wound layer, with value selection. At the same time, the winding ratio is varied from a selected opening value for the first wound layer at a selected final value for the last wound layer, at least near to a steady rate of change.

Title: Sewing machine fabric stacker - has stack plate with vertical movement to hold layers independent of fabric size
Inventor: IIZUKA TETSUO
IPC: D05B41/00
Filed: 1990-09-08
Abstract: Appts. to stack fabric workpieces at a sewing machine has a mechanism with a support arm on a rotary mounting at the sewing machine. A rack is fixed to the support arm and a lever, near the sewing machine, engages the rack with a pawl. This brings the fabric stack plate progressively downwards, in steps, when the clamp section bears on the workpiece on the plate. A spring pulls the support arm upwards. A grip rod releases the pawl from the rack to allow the plate to return to its start position. Pref. a blower fan below the fabric draper has its air stream directed at the fabric workpiece to blow it upwards. A second air blower, below the workpiece table, generates an air stream to direct the fabric down to the stacking plate. ADVANTAGE - Gives a fabric stack plate with a vertical movement to allow fabric layers to be stacked, regardless of workpiece size, for pockets or pocket flaps to be applied.

Inventor: KUECKENWAITZ HUGO ING GRAD
IPC: F02B19/04
Filed: 1990-11-22
Abstract: 1. Method for the approximate idealisation of a fuel-independent cyclic process for heat engines. 2.1 Examples of energy conversions in heat engines in practice show that there are still some aspects which require improvement (as regards efficiency  - crude oil supplies - pollutant-rich exhaust gases and noise - pollution of the environment). 2.2 The principal features of an improvement are:     - increase in the compression ratio (without knocking) - realisation of known ideal processes (in this case isochoric combustion in separate chambers)   - free selection of fuel (genuine multi-fuel engine) - combustion at a high temperature level (glow space, good ignition, operational reliability, association of H2O) - increase in power due to an increase in engine speed, principally in diesel engines (ignition delay without any effect) - economy under full load, part load and when idling (air cell insert - good starting conditions as well).   2.3 The arrangement shown provides an increase in efficiency particularly in fuel-injected engines without throttling and maximum compression. The reintroduction of simple two-stroke engines in certain sectors must surely make the above points possible.  (No air/fuel mixture scavenging) <IMAGE>

Title: Environment-friendly spray painting - where spray compsn. contains ultrafiltration throughput setting component and recirculated water conductivity is monitored
Inventor: WEPF HANSPETER
IPC: B05B14/462
Filed: 1991-11-19
Abstract: Environment-friendly spray painting using a water-thinnable two-component lacquer takes place in a spraying operation using a compartment with a water-spraying rear wall for collection and washing out of overspray in the waste water, which is sepd. into permeate and lacquer-contg. residue by ultrafiltration. The permeate is recirculated to the paint spraying stage, the lacquer-contg. residue is conc. in lacquer by water extn. such that the lacquer content is the same as for the paint spraying stage and it is returned to the fresh spray compsn. which contains a component for deceleration of polymerisation of the two-component lacquer and one for hindering coalescence of the lacquer. To the waste water a component is added for setting throughout on ultrafiltration, and the conductivity of the water recirculated to the spraying stage is monitored and held below a boundary value. ADVANTAGE - The process is environment-friendly with recirculation of the water and lacquer.
