Title: Hybrid communications system
Inventor: BEATTIE TIMOTHY A
IPC: H04K/
Filed: 1987-10-02
Granted: 1992-04-14
Abstract: ABSTRACT          "Hybrid Communications System"     A system for communicating instructions and commands to a plurality of remote integers capable of independent automatic action and of storing instructions for future action comprises a general method of communication (which issues the instructions and commands) and a specific method of communication (which impinges upon each individual integer when instructions peculiar to it are transmitted, enabling them to be stored).  The general method of communication is, preferably, radio transmission and the specific method of communication is, preferably, a steerable laser beam.  The system is especially useful in blasting, wherein a large array of electronically-programmable detonators can be programmmed and fired.

Title: Device for applying water-borne paint by means of high-speed rotary atomizers via direct charging or contact charging
Inventor: KLEMM HORST
IPC: B05B5/025
Filed: 1987-12-24
Granted: 1992-04-14
Abstract: Abstract In the application of water-borne paints, when direct charging or contact charging of the high-speed rotary atomizers is desired, difficult electrical insulation problems must be mastered, which make the existing units expensive.  In order to overcome these problems, a paint storage vessel is proposed, which is subdivided by a flexible insulation into two interior spaces which are each connected to their own distribu-tion line and to their own paint supply line, the connection of the ring main to the two distribution lines being effected with the interposition of an electrically insulating change-over mechanism.

Title: Microwave heatable materials
Inventor: HARRISON PETER
IPC: B05D5/12
Filed: 1988-01-12
Granted: 1991-09-24
Abstract: ABSTRACT            IMPROVEMENTS RELATING TO MICROWAVE HEATABLE MATERIALS            The invention provides that receptor films for use in microwave ovens for the browning and crisping of foodstuff are created by forming a composition which is liquid in nature and contains interactive particles. The composition is laid down in order to form a film which is then dried in order to fix the interactive particles in distributed form so that they will behave as an interactive layer when subjected to microwave radiation. It is suggested that the interactive particle layer should be covered by a protective layer such as heat curable varnish in order to isolate the particles from the foodstuff which will be adjacent thereto to be crisped and browned thereby. The composition comprises a cross linking and heat resistant resin acting as a binder so that when the composition is applied on a receiving surface, it is cured for example by subjecting it to heat to fix the particles in distributed condition.

Title: Method in the production of crystalline explosives
Inventor: SVENSSON LEIF
IPC: C07D257/02
Filed: 1988-04-21
Granted: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE     A method of initiating a crystal growth, prior to filtering off, from the mother liquor in which they were produced, of crystalline explosives, such as hexogen and octogen, produced by so-called Bachmann process or variations of this process. According to the invention, the mother liquor is, after the end of the chemical reaction proper, subjected to a pressure-heat treatment which initiates the partial dissolution of the crystalline explosives obtained in the process, giving rise, after cooling of the mother liquor, to larger crystals which may more readily be filtered off.  According to a further improvement of the invention a relatively pure octogen may be extracted from the mother liquor by way of a thermo-filtering of said liquor at a temperature of 60-110° C.

Title: Automatic gain control system
Inventor: LEIS MICHAEL
IPC: H03G3/20
Filed: 1988-09-02
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE An AGC system for controlling the gain of an amplifier includes an AGC multiplexer and an AGC circuit.  The AGC circuit receives an input signal from the AGC multiplexer and generates, in response thereto a gain control signal.  The AGC multiplexer operates in three modes.  In a first mode, in which the erased portion of a sector is being detected, the AGC multiplexer couples an input preset signal of a predetermined voltage level to the AGC circuit, enabling it, in turn, to generate a gain control signal to control the gain to a predetermined level.  In a second mode, the AGC multiplexer couples a signal related to the output signal from the amplifier to the AGC circuit, enabling the AGC circuit to generate a gain signal related to the output level of the amplifier.  In the third mode, the AGC multiplexer maintains its output signal constant, thus enabling the AGC circuit to maintain its gain control constant.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention generally relates to the mounting of win-dows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The inven-tion provides a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of an U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plasti-cally deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.

Title: Laterally releasable binding unit
Inventor: BOGNER MARTIN
IPC: A63C9/085
Filed: 1989-06-30
Granted: 1993-03-30
Abstract: Abstract Laterally releasable binding unit for holding the front end of a ski boot (12) comprises a base part (30) fixed relative to the ski, a release spring (13) arranged sub-stantially in the longitudinal direction of the ski and a sole clamp (29) having two limbs (14) and a hold down clamp (15). The one piece sole clamp is rotatably arranged on an upright carrier spigot (30) mounted on the ski (22), with the carrier spigot (30) representing the base part, and is vertically tiltably mounted about a transverse axis (36). A draw rod (38) passes through a slide bore (37') in a ball guide (37) within the carrier spigot (30) and contacts, by means of a support disc (39) secured to it at the rear, against a sub-stantially flat rear support surface (40) of the carrier spigot (30). The rear end of the release spring (13) is braced against an abutment (42) fixed relative to the sole clamp and thus presses this abutment against the front support surface (31) of the carrier spigot (30). The rear support surface (40') of the carrier spigot (30) and/or the preferably flat counter surface (39') of the support disc (39) above the draw bar (38), and/or the front support surface (31') of the carrier spigot (30) and/or the preferably flat counter surface (42') of the abutment (42) beneath the draw bar (38) are tilted relative to the perpendicular to the surface of the ski (22) in such a way that within a predetermined vertical tilting region (a) of the hold down clamp (15) the hold down force is significantly reduced relative to the normal release hold down force.

Abstract: A screening machine has a rotating screening drum for screening dirt or other material to a desired size through the screen openings, and is made so that it reduces clogging of the screen, even when rocks, dirt clods, and moist dirt is being screened. The rotating drum has interior brushes and a beater bar for keeping the material moving on the interior of the drum.   A holding bin and feeding conveyor is used at the input end of the machine and is positioned to empty into an input pulverizer or shredder, that has a powered drum that will break the dirt clods up.  The holding bin has a cover grate to remove excessively large rocks and the like. The  output  from  the  pulverizing  roller  also  drops material onto a grate through which the material passes before reaching the screening drum.   These grates are called "grizzly bars" and help in the classification process.  The screening drum can be converted to a mixer drum by lining the screen wall with sheet metal and removing the normally used interior brushes.
