Title: Heavy metal impact penetrator ammunition round - has heavy metal wires double coated with polymer resins, glued into casing for lower cost, high performance round
Inventor: DAUBEN PETER DR
IPC: F42B12/74
Filed: 1989-12-19
Abstract: A penetrator (1) for an impact round, built as a bundle of heavy metal wire (4) has a matrix (5) filled with a polymer resin e.g, epoxy resin, methacrylate or polyurethane. The wires are of a relatively high strength tungsten or tantalum or their alloys with coating material. The casing (3) of an impact penetrator round (1) is filled with a bundle of double coated heavy metal wires (4). A first coating (10) has good bonding properties and good tear resistance and completely encompasses the wires (4). The second coating (11) forms the previously coated heavy metal wires (4) to a high strength fibre bundle (2). Material for the first coating is a modified silicon or epoxy resin, the second coating is of modified epoxy resin. This second coating may be made to form a hexagonal cross section around the coated wires (4). The whole matrix is mounted in the casing (3) with adhesive. USE/ADVANTAGE - Ammunition mfr. Lower cost and greater strength. The damping properties of the first coating give improved performance when striking a target, esp. when the target is struck at an angle. Avoids metal forming and subsequent heat treatment operations in mfr.

Title: Prevention of smoke from gas from incineration process
Inventor: MARCKS ROLAND DIPL ING
IPC: B01D53/26
Filed: 1990-02-13
Abstract: When gas is cleansed by wet wash and subsequent re-heat this produces a billowy smoke cloud. The novelty is that a gas cooling stage is added between the wet wash and re-heat stages. Hot effluent gases are washed and cooled in a scrubber (3) before being fed to a cooler (4) and then re-heated in a heat exchanger (2). The cooling following the scrubber (3) is effected by ambient air. Pref. gas is cooled in a heat exchanger before entry into the scrubber and the heat re-used downstream to heat the effluent gas before release into the atmosphere. Prior to the scrubber, gases are cooled and condensation is removed such that subsequently re-heated gases do not generate cloud upon mixing with ambient air. Gases leaving the scrubber are cooled indirectly by ambient air.

Patent DE-4027887-A1 (DE)
Inventor: KOEPFF PETER DR
IPC: A23P10/20
Filed: 1990-09-03
Abstract: Described is a granular agglomerate consisting of dispersed particles of at least one solid and a binder holding the particles together in the agglomerate, pores remaining open between the particles. The agglomerate has the following characteristics: the binder is hydrous gelatine; the gelatine content, expressed as a percentage by volume, is lower than the pore content so that the gelatine does not completely fill the pores; and the amount of water contained, originating from the water content of the gelatine, is less than 2 % by wt. of the total weight of the agglomerate. The agglomerate is produced in an extruder, in particular a screw-feed extruder, to which the required amounts of gelatine and solids are supplied. A highly viscous composition is extruded as a continuous extrusion, dried to the required low water content and the extrusion granulated to give a granular agglomerate.

Title: Coating to keep engine block clean - has epoxy¨ type primer for adhesion to block and gloss or colour top coat of e.g. polyurethane and acrylic¨ resin or metallic paint
Inventor: LUKOSCHEK ARMIN
IPC: F02B77/04
Filed: 1991-08-07
Abstract: An internal combustion engine block has a heat-resistant surface coating for protection; this consists of a base layer of epoxy resin and a covering layer of acrylic, other resin, or metallic coating. The base is pref. based on epoxy and amide, whilst the top coat is pref. based on polyurethane plus acrylic. A dark coloured top coat increases effectiveness; thus a (e.g.) black top coat increases the emission and heat is lost more efficiently. As an alternative to epoxy/acrylic the coating can be a one or two coat metallic paint. Thus for example the top coat can be a metallic paint on a primer of an epoxy resin. ADVANTAGE - The prod. is useful for keeping the block clean. Its undercoat provides the bond to the engine block whilst the top coat provides the useful properties, so that the combination provides a long service life. The top coat can be coloured and have a high gloss, the latter aids cooling. (0/1)

Title: Simulating sequence of key strokes in program-controlled processor running applications - interrupting application processing to start keyboard servicing routine storing key codes words and time value
Inventor: BORDEWISCH UWE
IPC: G06F3/023
Filed: 1991-09-24
Abstract: The method for simulating a sequence of key strokes involves interrupting the processing of an application program module (APPL) when a keyboard interrupt signal occurs and starting a keyboard servicing routine for receiving and storing key code words and storing a time value associated with the code word. When a clock interrupt signal occurs the application program module is interrupted and processing of a clock interrupt routine started.

USE/ADVANTAGE - For use during setting of key code words into program-controlled processor which runs application programs. Sequences of key strokes can be defined by user and simulated as often as required.
