Patent DE-4118661-A1 (DE)
Title: Insulation for producing castings on or around workpieces - with a stationary closing element for closing a chamber filling tube ending in the casting tool
Inventor: JAUSS SIEGFRIED
IPC: B22D17/10
Filed: 1991-06-07
Abstract: The installation for producing castings on or around workpieces incorporates a casting tool and a closing element for closing a chamber filling tube ending in the casting tool. The closing element (11) is rigidly fixed to the casting tool (6), while the chamber filling tube (13) can slide axially. Pref., the closing element is detachable from the casting tool, while the chamber filling tube is held against the closing element by means of a thrust device (31). Such a thrust device incorporates at least one, and pref. several springs (31) located in holes (32) and pressing against a flange (30) of the chamber filling tube. Alternatively, the thrust device is based on the use of pneumatic or hydraulic cylinders. The closing element (11) forms a seal against an inner shoulder (28) of the chamber filling tube (13). Such a closing element can be a plate, or it can have a conical shape. The temporary gap between the closing element and the chamber filling tube is connected by means of ducts (7,8,9) with the space (45) accommodating a workpiece. The chamber filling tube is provided with an inlet opening (38). The end (40) of the tube is closed by a piston (41) of a thrust mechanism (44) based on a hydraulic or pneumatic cylinder. USE/ADVANTAGE - Can be used in the casting industry producing cpd. castings. Its main advantage over conventional installations with a sliding closing element is its highly compact construction. This eliminates a number of cooling/heating problems connected with the conventional installations.

Title: Cooling system for utility vehicle - has engine powered cooling unit with electric back=up motor
Inventor: HAGIN FAUST DIPL ING
IPC: B60H1/32
Filed: 1991-07-18
Abstract: The cooling unit (1) is normally driven by a hydrostatic transmission linking the cooling unit to the main engine (6). The back-up electric motor drive (8) is powered from the battery and/or an external coupling (11) to an external electric supply. This provides cooling when parked in a depot. The hydrostatic transmission operates in both directions enabling the vehicle to be moved by battery drive, while the electric motor can operate as a generator to charge the batteries while the vehicle is driven with the engine. An on-board transformer enables charging from the external power supply. ADVANTAGE - Versatile cooling system; simple, compact.
Patent DE-4124490-A1 (DE)
Inventor: JENA HANS DIPL ING
IPC: B25C1/16
Filed: 1991-07-24
Abstract: The cartridge (23) is composed of a plastic sleeve body (16) and a plastic cover (20). A first retaining space (46) for retaining a firing charge (52) and a second retaining space (48) for retaining a propulsion charge (60) are accommodated in the sleeve body (16). A plastic firing pin (30), which is flexibly connected to the cover (20), is immersed in the first retaining space (46). If pressure is applied by means of an impact bolt (66) onto the rear end (40) of the firing pin (30), the latter is moved forwards into the first retaining space (46), its sharp front impact end (32) acting on the firing charge (52) in order to detonate said firing charge. The firing charge (52) is accommodated in the shape of a funnel in a conical depression (53) in the first retaining space (46). The impact end (32) of the firing pin, which is immersed in the firing charge (52), produces friction in the firing charge material, and hence friction heat therein. As a result of this 'broaching detonating principle', it is possible to achieve reliable detonation of the firing charge (52) despite the use of plastic, which is considerably softer than metal, as the material for the sleeve body (16) and for the firing pin (30).

Patent DE-4127705-A1 (DE)
Inventor: GARTZEN JOHANNES PROF DR
IPC: B29B17/04
Filed: 1991-08-23
Abstract: The invention relates to a process for treating at least two materials which are secured together by an adhesive agent. Once such materials have served their purpose they are dumped or burned. The proposal is for a process by means of which one reduces the need for dumping and avoids the problems of incineration. This is achieved in that the adhesive is dissolved by a solvent which does not dissolve the materials themselves so that the adhesively secured materials can be separated and recycled on their own.

(meth)acrylate gps., and/or with photoinitiators and/or photosensitisers, esp. 2-methyl-1-(4-methylthio-phenyl)-2-(4- morpholino)-propan-1-one (IV) pref. in combination with a thioxanthone. (II) is an isocyanate contg. methacrylate gps. or an adduct of hydroxyethyl (meth)acrylate with 2,4-diisocyanatotoluene. (IIIA) contains aromatic structures and pref. has mol. wt. 500-50000 whilst (IIIB) is a phenoxy resin esp. with mol. wt. 10000-30000. The baking time is pref. up to 10 s. USE/ADVANTAGE - The structurised films are used as resist with intermediate protective function in structure transfer by electroplating,  wet and dry etching and ion implantation and as protective and insulating film in electrical, esp. semiconductor technology. Baking greatly reduces the exposure time, by a factor of 20-30 and swelling during development. Very fine, dimensionally accurate structures e.g. of 2-10 microns, can be produced even with short exposure times (under 10 s.). The structurised films or reliefs have shape edges, high resolution, a flawless homogeneous surface and good heat distortion resist
