Title: Plastics pallet mfr. for high strength - by forming recesses in upper plate to hold inserted reinforcement rods and cover to prevent rod corrosion
Inventor: AEPFELBACH KLAUS
IPC: B65D19/00
Filed: 1991-12-19
Abstract: The pallet is made with recesses (6) in the support plate (4), towards the support surface. each to hold reinforcement rod(s) (8), with a clear width/length/depth sufficient to accommodate the rod (8) dimensions. After the pallet is injection moulded, the rods (8) are laid in the recesses (6), and the recesses are covered. The reinforcement rods (8) are pref. inserted into the holding recesses when the support plate (4) has cooled fully. The covers for the rod recesses are of plastic, bonded into place by welding or adhesive. The recess covers may be produced by injection moulding, at the same time as the pallet (1) is shaped, in a single operation. The reinforcement rods (8) may be mechanically bonded to the lower section of the pallet, by screwing into place, before the recess covers are fitted. The upper deck (2) is pref. bonded to the lower deck (3), at all the joints (16), in a gas tight seal by welding or adhesives. The recesses (6) for the rods (8) are U-shaped channels, with downwards extensions at the point(s) where the rods (8) are screwed through to the lower section (3), to give a sealed shrouding, with a gas-tight seal where the rods (8) project through the extensions. The lower (3) and upper (2) sections are welded or adhesive bonded at the butt joints (16) between them. ADVANTAGE - The pallets are simply and cheaply produced, have the required strength to support the carried goods - esp. in containers - with protection for the reinforcement rods against the environment to prevent rusting and corrosion.

Title: Bolt with self-locking thread effected by thread change - has enlarged flank angle between core dia. and thread dia. which is smaller than flank dia.
Inventor: ISENBERG RAINER
IPC: B23G5/00
Filed: 1992-03-05

Title: Car headlamp with protective device - rendering gas discharge bulb inoperative if headlamp lens is broken in accident
Inventor: STEIN JUERGEN DIPL ING
IPC: F21V9/06
Filed: 1992-05-02
Abstract: A car headlamp uses a gas discharge bulb as a light source with a reflector behind it and a protective arrangement in-front of it to prevent the bulb's illumination should the headlamp lens be damaged in an accident. This protective device is arranged so that, if the intermittent stress on it exceeds a certain value, it overbalances and strikes the bulb so as to render it inoperative. The shape of the device is that of a C surrounding the bulb with the upper end free and the lower end pivoted on a mounting below the bulb. Alternatively, the pivoted end is attached to the reflector. ADVANTAGE - Protects people from possible UV radiation and high voltage when discharge bulb is exposed with broken headlamp lens.

Patent DE-4230116-A1 (DE)
Title: Adhesive contg. aliphatic poly:ol and aromatic di:anhydride - is soluble in aq. alkali and used to assist machining e.g. of small lanthanide alloy permanent magnets from stacked plates
Inventor: ZAPF LOTHAR DR
IPC: H01F41/02
Filed: 1992-09-09
Abstract: Adhesive (I), which is soluble in aq. alkali, contains a mixt. of an aliphatic polyol (II) and an aromatic dianhydride (III). The (II):(III) molar ratio is 1:2 to 2:1 (I) may also contain a liquid epoxide resin of low viscosity, pref. bisphenol-A diglycidyl ether, bisphenol-F diglycidyl ether and/or cycloaliphatic epoxide resin; a silane-type adhesion promoter; water-soluble resin; and/or alkali-soluble resin. (I) is applied to the pts. to be bonded, then these are joined and (I) is hardened thermally. The bonded pts. are machined, then the adhesive is dissolved in soda soln. or aq. caustic alkali soln.. USE/ADVANTAGE - (I) is used to assist material machining and for bonding metals, esp. lanthanide alloy permanent magnet components (claimed). It is also useful for bonding other metals, glass or marble and esp. in machining precious stones. (I) gives the high intrinsic bond strength needed for machining very small magnets, e.g. dice with an edge length less than 5 mm, from a stack of wafers. Unlike other adhesives used for this purposes, it can be dissolved without using hazardous, flammable or toxic solvents. In an example, adhesive (IA) was prepd. by stirring 2.18 g pyromellitic dianhydride into a mixt. of 1.5 g triethylene glycol and 1.35 g epoxide resin ('Epikote 215'; RTM), giving a viscous compsn. which was ready for use and has a pot life or ca. 6 h. This was brushed onto 3 mm thick Sm-Co permanent magnetic alloy plates. 15 plates were made into a stack, ca. 5 cm high, bonded to a marble plate and fixed with a screw clamp. The adhesive was cured ca. 3 h in an air circulating oven at 160 deg.C. After cooling, the adhesive had reached its final strength and the stack could be machined. Squares with an edge length of 3 mm were made from the stack with a fret saw, giving a stack of 15 dice with 3 mm edges. These were sepd. by breaking the marble plate and placing them in 3% aq. NaOH soln. The adhesive dissolved completely after ca. 10-12 h or more quickly if the NaOH soln. was dissolved was warmed. The magnets, were washed with water, cleaned in an ultrasonic bath at 60-70 deg.C, etched, polished chemically and dried. The surface quality was completely satisfactory and comparable to that of magnets made using a commercially available 2-component methacrylate adhesive.
Patent DE-4231879-A1 (DE)
Title: Recovering sodium aluminate solution from an aluminium etchant bath - to use as phosphate precipitating agent in clarifying plant
Inventor: BRODALLA DIETER DR
IPC: C25D21/16
Filed: 1992-09-23
Abstract: An EO etchant bath is directly connected to an E6 etchant bath for decorative surface etching of aluminium surfaces, the EO bath being used to remove oxide layers from ancillary electrodes and frames. Either continuously or at intervals the EO bath soln. with comparatively high sodium hydroxide and low aluminium concentration is fed into the E6 bath. Additionally rinsing water from the rinser following the EO etchant bath is fed back into the EO bath and E6 solution is removed to ensure that the concentration of dissolved aluminium does not exceed a critical value. ADVANTAGE - The etching process is controlled whilst the removed solution of sodium aluminate is used to precipitate phosphate out of water in a purifying plant.

Patent DE-4234323-A1 (DE)
Title: Electronically controlled lock operating system - has active key transmitting EEPROM programmed code via fibre-optic conductors for motorised latch release and manual unlocking
Inventor: SCHREIBER HANS DR MED DR MED
IPC: G07C9/00
Filed: 1992-10-12
Abstract: The system uses an active key (208) whose EEPROM is pre-programmed by a separate module (200) in known fashion via an inbuilt opto-coupler (214,215), microprocessor (210) and battery (211). A signal button (212) on the key (208) transmits the code to the lock during a limited time (239) via the lock's internal fibre-optics. On recognition of the code a piezo or otherwise pulsed micromotor (220) operates an eccentric cam (227) to release a sliding latch (223) which at all other times prevents rotation of the bolt in the lock cylinder. The lock is then operated manually by the key (208) which can only be inserted/withdrawn when in a neutral orientation to ensure resetting of the latch (223). USE/ADVANTAGE - Minimises battery load by limiting transmission time and using watch-type stepping motor for latch release. Enables matched series of individual codes to be stored in external programmer with convenient master key facility.

The drawer can only be removed from the carrier when the pin is removed from the socket. ADVANTAGE - Guarantees PCB cannot be removed if leads are connected in the socket, preventing danger of forgetting about leads and pulling PCB out and causing damage.
