Patent DE-4232874-A1 (DE)
Inventor: BAUER VOLKER DR
IPC: C11D17/06
Filed: 1992-09-30
Abstract: Detergent anionic surfactant granules of high anionic surfactant content can be produced by neutralization of anionic surfactants in their acid form using a powdered neutralizer, with simultaneous granulation and, as needed, simultaneous drying. Preferably this involves the neutralization of fatty alcohol sulfonic acids, alkyl benzene-sulfonic acids and/or  alpha -alkylsulfonic acid methyl ester acids with an excess of sodium carbonate, and the simultaneous granulation with other liquid components, in particular with anionic surfactant pastes, aqueous hydrogen peroxide solution and/or a zeolite suspension. This production can be effected in any apparatus in which neutralization can be carried out simultaneously with granulation and drying. Preferably this preparation takes place in a continuous fluidized bed system.
Patent DE-4235638-A1 (DE)
Inventor: GIESEN FRANZ-JOSEF
IPC: C08L83/05
Filed: 1992-10-22
Abstract: In the novel process for the production of a high-quality silicone foam by the free-foaming method, a two-component addition-crosslinking system is used which comprises a component A containing silicone polymer having at least two double bonds per molecule (preferably vinyl groups), an organic platinum catalyst complexed with butinol, pyrogenic silicic acid and water and optionally further additives, and a component B containing silicone polymer having at least two double bonds per molecule (preferably vinyl groups), pyrogenic silicic acid and polydimethylhydrosiloxane as SiH crosslinking agent. The two components A and B are mixed, after which the reaction mixture is charged with compressed gas (preferably compressed air or nitrogen) in a storage (stock) container or the like over the course of several hours, so that the gas is in dissolved form in the mixture. The reaction mixture is subsequently brought to reaction with warming, preferably by application as a film in the desired film thickness, giving a fine-pore, homogeneous silicone foam.

Title: Producing thermoplastics reinforced with LC resin fibres - using mixt. with LC(s) whose transition temp. exceeds processing temp. and extruding under specific conditions
Inventor: TOMITA TAKASHI
IPC: B29C48/05
Filed: 1993-01-20
Abstract: A composite material is produced with a matrix of thermoplastic resin and a liq. crystal resin whose liq crystal transition temp. is higher than the minimum moulding temp. for the thermoplastic and which is formed into a fibrous structure as a reinforcement. In the process the composite material is extruded at an apparent shear speed of 3 x 10 power 2 to 10 power 5 sec-1 (sic) above the liq. crystal transition temp. so as to form fibres of the liq crystals with a length ratio of more than (sic) 3 in the matrix resin. A wide variety of thermoplastic polymers can be used (or their modifications or mixts.). Any type of liquid crystal is suitable if its transition temp. is (preferably 20 deg.C) higher than its lowest moulding temp.; its concentration must be chosen appropriately to form its fibres. Under the correct conditions the liq. crystal resin is formed into a fibrous structure in the extrusion made. ADVANTAGE - The prods. can be reused. The liquid crystal fibres provide reinforcement.

IPC: G11B23/03
Filed: 1993-11-30
Abstract: The occurrence of scratches on the recording disk 150 due to sliding of the shutter 160, 161 is prevented by slidably inserting the first and the second shutters between the tray 130 and the case 101 on the opposite side to the recording disk accommodating portion. The first shutter 160 simultaneously opens and closes the case side driving shaft insert hole 121, the case side head insert hole 122, the tray side driving shaft insert hole 132 and the tray side head insert hole 133. The second shutter 161 opens and closes the terminal hole 142. The second shutter 161 is opened independently of the opening operation of said first shutter 160 and is held in a position where it does not close the case side driving shaft insert hole 121, the case side head insert hole 122, the tray side driving shaft insert hole 132 and the tray side head insert hole 133 in the opened state, and is energized in the closing direction through the first shutter 160 as the spring 162 as energizing means energizes the first shutter in the closing direction.

Abstract: The invention relates to a tractor (12) for aircraft having a U-shaped chassis (10) and in each case one lifting device (18) and supporting structure (22), which are arranged on the chassis (10), for the nose undercarriage (20) which is located in the recess (26) in the chassis (10). The lifting device has a lifting arm (30) which can be pivoted by hydraulic means (56) on a bearing (38, 40) which is fixed to the frame and, at its front end, has a retaining part (28) for a spherical load-supporting point (66) which is arranged on the nose undercarriage (20). In addition, the supporting structure (22) has a platform (76), which can be displaced on the chassis (10), for supporting the nose undercarriage (20) when it is lifted off the taxiway. In order to be able to lift the aircraft off the taxiway (94) using simple means and without any loads which are atypical for a nose wheel, and to be able to anchor the said aricraft in the chassis (10) for the towing process, it is proposed according to the invention that the lifting arm (30) be guided parallel to the chassis and that the retaining part (28) be arranged in a guide (60), which is aligned horizontally throughout the entire lifting movement, such that said retaining part (28) can be displaced in a limited manner along the lifting arm (30). <IMAGE>

Filed: 1993-12-17
Abstract: The clutch housing has several tongues engaging behind a membrane spring (6). The free ends of the tongues (12) which are each orientated in the same circumferential direction, run substantially parallel to the spring (6). After the membrane spring (6) has been turned a restricted amount, limited by at least one stop to fit between the tongues (12) and clutch housing, the free tongue ends engage behind the spring (6) with supporting tongues (16) to press against the support bearings (10) of the clutch housing. The free tongue ends interact with at least one non-return aid such as a centring pin fitted on the clutch housing to prevent the membrane spring from turning back. Each tongue can have its own stop for the membrane spring. The stop can be formed by the first part of the tongue running at right angles to the spring.

Title: Releasable connector for jewellery esp. chain
Inventor: APPEL RICHARD
IPC: A44C5/20
Filed: 1994-03-29
Abstract: A cylindrical receptacle (2), open at one end (21), accepts a plug (1). Within the receptacle a spring (10) at its closed end supports a thrust component (11) located on the cylinder axis. An internal bushing (12) guides axial movement of plug head and thrust component and has two shoulders (25). The plug head has a cylindrical section supporting a transverse, approx. cuboid section (4), of length and breadth greater and smaller respectively than the dia. of the cylindrical section. The leading face of the cuboid is pref. wedge-shaped or convex to fit a similar recess on the thrust component. The plug is engaged by pushing it against the thrust component, compressing the spring, and then rotating to mate with the thrust component and simultaneously lock the projecting ends of the cuboid behind the bushing shoulders. Two stops limit rotational travel.
