Title: Steel chisel used in hammers for breaking concrete etc. - made by through hardening and tempering low alloy steel contg. chromium, molybdenum and vanadium
Inventor: FORSTMANN KARL-HEINZ PROF
IPC: B25D17/02
Filed: 1978-07-07
Abstract: Chisel is inserted in the driving bush of the hammer, and is made of a hardened and tempered alloy steel with compsn. 0.25-0.7% C, 0.15-2.0% Si, 0.3-2.0% Mn, 0.5-2.0% CR, 0.15-0.5% Mo, and 0.05-0.25% V. The chisel is hardened and tempered throughout its entire cross-section to obtain a tensil strength (UTS) of 1200-1600 N/mm2. Chisel is pref. made of the steel 42 Cr Mo 4; or 50 Cr Mo 4; or 50 Cr V 4; and is used e.g. for breaking up stone or concrete; or for breaking up hot slags etc. in steelmaking- or smelting- works. As compared with chisels made of conventional materials, the invention uses a lower alloy content reducing material cost, but the working life of the chisels is increased up to twice the previous life, and fatigue fractures are virtually nil as compared to 15-20% for conventional chisels.

Title: Boat carrying trailer with launching aid - has several wheeled struts releasably secured boat to stern
Inventor: JOISTEN ADOLFO
IPC: B60P3/10
Filed: 1978-10-27
Abstract: The boat launching aid consists of several struts (17), releasably clipped to the boat stern and carrying a pair of wheels (18) to enable the boat to roll off the trailer and into the water. The rollers prevent the stern from being damaged by the slipway, while the trailer does not have to be rolled into the water. The system protects the trailer as well as the boat, during launching. When the boat has been launched, the strut is unclipped and stored on board. The design provides a simple, low cost fitting for any trailer launched boat.
Patent DE-2848618-A1 (DE)
Title: Closing winding slots in electrical armature - is by cold deformation of core tooth tips to make required shape
Inventor: KOFINK WOLFGANG DIPL ING
IPC: H02K3/487
Filed: 1978-11-09
Abstract: To assist with easy automatic coil insertion the winding slots are made the full width throughout, but to limit magnetic noise, ripple and cogging effects it is desirable to employ closed or semi-closed slots. Both requirements are achieved by dimensioning the tooth tips such that, after coil insertion, the tips can be deformed to the required shape. The tip deformation may be carried out by a variety of cold forming methods, for example rolling or pressing. As well as giving the required magnetic effects, the deformed tooth tips can also be made to retain the coils in the slots. The technique can be employed on both stators and rotors. The application is mainly to small size machines, for example alternators for vehicles.

Title: LV switch auxiliary unit - has adjustable delay mechanism with intermediate lever connected to bellows
Inventor: AMMANN ECKHARD ING GRAD
IPC: H01H7/03
Filed: 1979-04-14

Title: Staircase automatic illumination controller - has brightness setter with variable resistance link of bridge rectifier
Inventor: POLLACK WOLFGANG DR ING
IPC: G04F1/00
Filed: 1979-05-16
Abstract: The intensity of staircase illumination is gradually dimmed by phase control of the rectifier to avoid sudden darkness which may disorientate people walking in it. The brightness controller of the illumination circuit is activated by a press button switch initiating the discharge of a timing capacitor and the dimming is set by a variable resistance of the coupling unit. The capacitor forms the load of a rectifier bridge with a controller in its setting circuit.

Title: Maintenance of surfaces exposed to soiling - by application of film-forming substance in an organic liquid
IPC: C09D5/00
Filed: 1979-05-17
Abstract: Internal or external surfaces exposed to soiling are coated with a film-forming compsn. in an organic liq. medium, which after drying leaves a protective layer contg. or absorbing moisture. After soiling, the surface is cleaned with an aq. medium, opt. with mechanical action, or by further application of the film-forming compsn., in each case leaving at least part of the original protective layer on the surface. Used for protection of house facades, metal window frames, advertising surfaces, animal cages, etc. and also internal surfaces, e.g. windows, staircases, railway coaches, medical and sanitary areas, swimming baths, animal stalls, etc. Also for carpets, curtains, furnishings, etc. Use of an organic medium, instead of the aq. medium claimed in the parent patent, allows application of water-insol. protective coatings which are resistant to weathering.

Title: Decorative panel for motor vehicle interiors is mfd. - by subjecting surface of resin impregnated substrate to deformation before crosslinking
Inventor: LANDLER JOSEF
IPC: B05D3/12
Filed: 1979-07-24
Abstract: Laminated article is produced by subjecting the surface of a substrate carrying a crosslinkable resin layer to at least partial deformation before the crosslinking is allowed to take place. Pref. the partial deformation is carried out by subjecting the surface to treatment with a roller fitted with tabs or strips producing the decorative effect. Alternatively, the deformation may be effected using an embossing tool and the embossing may be associated with thermal treatment leading to hardening. Decorative, motor vehicle interior fittings which are resistant to ultra-violet radiation may be formed.

Title: Laundry article folding appts. - includes electronic control to initiate operation of folding device to give desired amount of edge overlap
Inventor: SCHUSTER WOLFGANG
IPC: B65H45/18
Filed: 1979-11-14
Abstract: Appts. includes conveyors driven by a regulatable motor for conveying the articles before and during the folding procedure. A tacho-generator (33) associated with the conveyor motor (21) supplies a voltage to a voltage converter (34) in which it is converted into a counting frequency and introduced into a length measuring electronic counter (35). When a photo-electric detector (38) detects the rearward edge of the article (W1) the counting frequency is doubled and a control impulse initiates operation of the folding device taking into account the overlap of the folded edges and compensating for the operational delay of the folding, driving and control devices. The overlapping of the laundry items remains constant under varying operating conditions.
