Title: Method and apparatus for cutting coated workpieces of wood or the like
Inventor: KUHN REINER
IPC: B27G19/10
Filed: 1990-12-15
Abstract: In a method and apparatus for severing plate-like workpieces (6) of wood or the like with a covering layer (5) of plastics using a manually-operated circular saw (1) which can be guided along a fence (7), firstly the covering layer (5) is severed by down-cutting in each case in one scoring position, displaced transversely to the sawing direction, of the saw blade (4) and then the entire cross-section of the workpiece (6) is severed by up-cutting between the scoring positions. 
<??>It is thus possible to use the saw blade (4) for scoring as well, an additional scoring saw blade being unnecessary. The manually operated circular saw according to the invention is, accordingly, cheaper and lighter.

Abstract: A programmable controller comprises means for keeping track of the next step to be executed in the program running therein and for storing this data in a discrete location. Head addresses corresponding to the steps are stored in a table (5B) which acts as a pointer to the program corresponding to the active step. Means (8,9) are provided to keep track of transition criteria for moving from one step to the next, and a table (5C) is maintained containing data on the number of the steps which will be subsequently active and the corresponding step identification numbers, which serves as a map of the transits between the steps. The invention is especially useful in debugging programs since the active step is always determinable at any time. Also, it is easy to change the path through the program by manipulating the table data, for example to test different branches or subroutines of the program.

IPC: F02P7/02
Filed: 1990-12-19
Abstract: The invention relates to an ignition signal (Z) distributor in a high voltage static distribution system, in which according to the invention the address signals (address lines A0, A1, A2) which are generated by a microcomputer (2) and determine to which downstream ignition output stage the respective ignition signal (Z) is connected are fed to a flip-flop component (3). The flip-flop component (3) accepts these address signals (address lines A0, A1, A2) during the open time of the ignition signals (Z = 0) and stores them at least during the subsequent closed time of the ignition signals (Z = 1). Said signals are fed to a decoder (4) as stored and constantly present address signals (address lines X0, X1, X2), which decoder transmits the drive signals Y1 to Y8 to the ignition output stages as output signals. In this way, fault-induced address changes as a result of synchronisation errors of the microcomputer (2) during the closed time no longer lead to misfirings.

Title: Light tight cassette
Inventor: LOEWE ERHARD
IPC: G03B27/58
Filed: 1990-12-24
Abstract: A light-tight cassette for a spool of strip-shaped, light-sensitive material of varying thickness is specified, which consists of a light-tight housing formed by two housing sections, and is provided with a film exit slit which extends parallel to the axis of the spool and can be adjusted in width. 
<??>The adjustability of the width of the slit is effected when the two housing sections are arranged relative to one another under pretension in such a way that the slit assumes its largest width and that a clamping device is provided which acts against the pretension and with which the width of the exit slit can be set from outside. The adjustable exit slit enables strip-shaped material of varying thickness to be uniformly unwound without its surface being scratched.

Abstract: Fuel-delivery valving (60) is operatively mounted in an axially-extending centre bore (65) of a rotor (50) of a high-pressure fuel-injection pump (58). A valve element (66) of the valving axially shifts between an open position in which a charge of fuel generated by the pump (58) is transmitted as a pressure wave to a fuel-injector nozzle (18), and a closed position in which a pump charging chamber (56) is sealed from an injection line (90,88,17) and the injection line (90,88,17) is vented to a low-pressure line (104) so that secondary pressure waves reflecting from the injector nozzle (18) will be routed to the low-pressure line (104) for dissipation therein rather than rebounding from the delivery valve element (66). This improves engine operation efficiency and eliminates secondary injection of fuel by the injector nozzle (18) and high hydrocarbon and smoke emissions. One embodiment has a fuel-delivery valve operatively mounted in each discharge fitting of a hydraulic head assembly of the fuel-injection pump.

Abstract: The present invention relates to a tamper indicating tape (10) made from a film (12) capable of splitting internally for use with a package to indicate opening of the package. In grocery stores, packages are subject to entry by various classes of tamperers. One type of tamperer opens the package, consumes the contents thereof, reseals the package, and places the resealed package back on the shelf. Another type of tamperer opens the package, introduces a foreign object therein, reseals the package, and then places the resealed package back on the shelf. This invention provides a tamper indicating tape (10) for use with a closure or container. The tape comprises a film including phase separated polymers. Colored indicia (18, 20, 22) are applied to opposing major surfaces of the film indicative of a condition that someone has tampered with the tape, e.g., tape removal and reattachment, or abrading. The film further bears a layer of adhesive thereon as a means for adhering the tape to a portion of a container or to a closure tape on a can lid. When the film of the tamper indicating tape is internally split, one set of colored indicia is obscured and the other set of colored indicia is rendered perceptible. When the film is abraded to remove the perceptible set of colored indicia, the aforementioned obscured set of colored indicia is rendered perceptible.

The apparatus automatically produces an evaporation cycle, a solvent reconstitution cycle, and a re-evaporation cycle thereby significantly reducing previously required costly manual procedures.

Abstract: A method and apparatus for enabling analysis of a material (16, 42) by applying a cooling medium (20, 54) to cool a thin surface layer portion of the material and to transiently generate a temperature differential between the thin surface layer portion and the lower portion of the material sufficient to alter the thermal infrared emission spectrum of the material from the black-body thermal infrared emission spectrum of the material. The altered thermal infrared emission spectrum of the material is detected by a spectrometer/detector (28, 50) while the altered thermal infrared emission spectrum is sufficiently free of self-absorption by the material of the emitted infrared radiation. The detection is effected prior to the temperature differential propagating into the lower portion of the material to an extent such that the altered thermal infrared emission spectrum is no longer sufficiently free of self-absorption by the material of emitted infrared radiation, so that the detected altered thermal infrared emission spectrum is indicative of the characteristics relating to the molecular composition of the material.

Abstract: In moulds for continuous casting of polygonal strand cross-sections, especially with quadrangular or hexagonal cross-section, the mould cavity (6) can have different geometrical shapes on the pouring-in side (4) and the strand outlet side (5). A better cooling of the crust of the strand is to be achieved by a targeted deformation of the strand cross section within the mould, in order to improve the strand quality and in addition to increase the casting speed. It is proposed for this purpose to provide, in each peripheral section of the mould cavity (6), a cross-sectional enlargement (7) in the form of a bulge (9), the extent (10) of the bulge (9) decreasing in the running direction (11) of the strand, at least along a partial length (12) of the mould cavity (6), such that the cross-sectional shape of the strand is deformed during passage through the partial length (12) of the mould cavity (6). <IMAGE>
