Title: Apparatus for shuttering concrete end surfaces, and production processes for joints and cavities by means of this apparatus
IPC: E04G11/04
Filed: 1987-02-06
Abstract: The subject matter of the invention is constituted by apparatuses for shuttering end surfaces of panel-like and wall-like reinforced-concrete structural parts, as well as processes to produce construction and expansion joints, in particular watertight joints using sealing strips, and cavities by means of these apparatuses. According to the invention, the apparatuses are composed of a mechanically or pneumatically or hydraulically expanding core part, arranged between the reinforcement layers, of the border parts, securing the concrete covering, between reinforcement and shuttering, and of sealing elements which are arranged between border and core part in the region of the reinforcement. For the pneumatically and hydraulically expanding core parts, the invention proposes inflatable bodies comprising a flexible sheath which simultaneously adopts the function of the sealing element. For the sheath, use is made of two-ply fabrics which can only be inflated to a limited extent under the inflation pressure because the two webs of the two-ply fabric guarantee the fixed web spacing by means of pile threads woven into the two-ply fabric. Inflatable bodies comprising two-ply fabrics contribute to shuttering for joints, shuttering installations and cavities being producible in a very simple and cost-effective manner, this improving the commercial viability.

Title: Illumination device containing a liquid-filled optical waveguide
Inventor: NATH GUENTHER DR
IPC: F21V9/16
Filed: 1987-02-16
Abstract: The invention relates to an illumination device which comprises a liquid-filled plastic tube. The refractive index of the filling liquid is greater than that of the tube material. The filling liquid contains a fluorescent dye. Primary light reaching the liquid through the tube excites the dye to fluoresce. The majority of fluorescence radiation propagates along the tube through total reflection, so that concentrated fluorescence radiation of relatively high intensity is available at one end of the tube, which is provided with a transparent plug or a photodiode. The fluorescent dye contains a perylene compound; the plastic tube preferably comprises TFB and the filling liquid preferably comprises triethylene glycol.

Title: Oil-cooled piston for internal combustion engines
Inventor: FUCHS REINHOLD
IPC: F01M1/08
Filed: 1987-03-14
Abstract: In a piston with a screwed-on upper part (1), in which a cooling oil chamber exists between upper part (1) and lower part (2), from which space blind cooling oil bores (8) radiate outwards, it is proposed to improve the cooling oil supply to the bores (8). Improvement of the oil supply of the cooling oil bores (8) is achieved in that in the direction of the piston head, above the cooling oil bores (8) radiating obliquely upwards, a cooling oil collecting grille is formed by means of an annular rib. The annular rib (12) ensures that cooling oil is collected over the entire circumference of the cooling oil chamber (9) and uniformly distributed to the cooling oil bores (8). <IMAGE>

Title: Blower-type sprayer for discharging liquid plant protectives in hop fields
Inventor: BEHRINGER PAUL DR
IPC: A01M7/00
Filed: 1987-04-13
Abstract: A blower-type sprayer for discharging liquid plant protectives in hop fields has an axial blower for generating a carrier-air stream. Two vertical walls narrowing upwards are attached to the circular air-guide plates of the axial blower. The nozzle linkage having the uniformly distributed nozzles is fastened to the outer edge of the rear wall. The position of the nozzle-outlet orifices is in the direction of the air stream. A rectangular plate having a narrow transverse plate is located on both sides on the outer edges of the front wall and on the free-standing legs of angles. This rectangular plate is adjustable and is pressed against the outer edge of the front wall and against the free-standing legs of the angles by a continuous strip. By advancing this rectangular plate, the excess air in the lower region is reduced and this air is additionally guided upwards. Three adjustable flaps located between the two vertical walls serve for allocating or regulating the air.

Patent DE-3740054-A1 (DE)
Inventor: ELSER DIETER
IPC: B62D5/22
Filed: 1987-11-26
Abstract: Known hydraulic rack-type assisted steering systems, comprising a hydraulic jack located parallel to the rack, have two casings separate from one another and therefore require considerable space. In the new system, the elements which are in a drive relationship are located in a one-piece casing and are placed at precise distances from one another, and are housed in the most compact manner possible. The drive pinion (5) is mounted, with a limited possibility of rotation, on the steering column (4) in order to provide play in the control. The overall dimension in the axial direction of the said steering column is thereby reduced. The drive piston (2) engages by means of a toothed pusher directly with the drive pinion (5), in such a way that the engagement planes of the rack (1) and drive piston (2) are mutually facing. In this way the design height can be reduced.

Title: Top for chimneys
Inventor: PARIL HUGO
IPC: F23L17/02
Filed: 1987-12-01
Abstract: The invention relates to a top for chimneys, the chimneys being lined against sooting. A chimney top of this type is to be improved in such a manner that the waste gases are made to condense, in other words a so-called sooting takes place. Toxic substances are not to pass into the atmosphere either. This is achieved by a baffle wall, e.g. a baffle cone (6), being provided across the chimney cross-section and this cone lying within fresh-air guides (pipe pieces 8) which have a spacing (cf. 9) from one another in the circumferential direction and have a cooling effect on the smoke gases flowing by. <IMAGE>

Title: Material structure in web form and its use as a gap seal
Inventor: KOCH ROBERT
IPC: B32B3/12
Filed: 1988-01-09
Abstract: The subject-matter of the invention is a web of material which is to be elastically flexible in one direction and to seal off the gap between two surfaces capable of movement relative to one another. In particular, the gap is to be between a fixed surface and a surface which is forcibly adjustable relative to the first surface. The web of material is to be attached to the fixed surface along one edge and to rest with the opposite edge on the adjustable surface. According to the invention, the web of material is to comprise two webs (C, D) of a fabric (1, 2) provided with a gastight coating, the spacing between which is variable, the permissible maximum spacing being determined by fibres which are resistant to tension but soft in compression and in terms of bending, these fibres being arranged between the coated webs of the fabric (spaced fabric). Attached to the outside of at least one of the coated webs of fabric is at least one flat spiral spring at points which are at least approximately uniformly distributed along the length of the said spring, and, more particularly, in a direction running between the edge of the web of material to be fixed and the opposite edge of the web of material, this being the direction of flexibility. The space between the coated webs of fabric is closed in a gastight manner all the way round and control means effect controlled intake and release of a gas to or from the cavity formed in this way (Fig. 1). <IMAGE>

Title: Method for producing a matching layer for ultrasonic transducers
Inventor: BURGER HANS-JOACHIM
IPC: G10K11/02
Filed: 1988-03-21
Abstract: For the purpose of producing an ultrasonic transducer, the piezoceramic is to be provided in a simple and cost effective way with a matching layer of specific thickness. The aim in this case is to dispense with a previously customary application of bonding agent or cement, since unavoidable differences in thickness of the adhesive layer have proofed to be disadvantageous. This is achieved by inserting piezoceramic into a mould and pouring a non-cured (hardened) formulation onto it. Before and during the encapsulation (potting), the mould is evacuated, and the formulation is intended to act as matching layer. A plate which is placed on the formulation with its side which is provided with a parting compound (mould release agent) is used to squeeze out the excess mass of the formulation down to the desired thickness of the matching layer. After curing, the matching layer is removed from the mould together with the piezoceramic.
