Patent DE-2519112-A1 (DE)
Title: Jolt-absorbing mount for snow plough or road-sweeper ploughshare - has elastically deformable support connected to scraper bar
Inventor: REISSINGER GOTTFRIED DR
IPC: E01H5/06
Filed: 1975-04-29
Abstract: The snow-plough, or road-sweeping machine, has a carrier device (21) which can be coupled to a vehicle, pref. via a height-adjusting device. This carries a ploughshare (26), and one or more support members extending forwards at an interval below the ploughshare, able to swivel upwards about an axis across or at an angle to the line of travel. At the front end it is connected to a scraper bar, the interval from the bottom edge of the ploughshare being bridged by an intermediate member moving with the support member, so as to be tilted over any obstacle encountered. The support member (31) is elastically deformable, while the intermediate member (32) is more resilient, at least in the area of its connection to the scraper bar (27). Structure is simple, and resistant to jolt stresses.

Title: Bulk material unloading mechanism from vehicles - has guide plate with switch in leading edge controlling movement
Inventor: BUETFERING FRANZ
IPC: B65G67/42
Filed: 1975-05-12
Abstract: The mechanism unloads vehicles carrying material in bulk, having a tipping platform on a fixed base alongside a hopper. A guide plate runs along the platform for its entire length on the side nearest the hopper, covering the intervening space between the latter and the vehicle, and slides to and from the hopper. The edges of the plate (6) coming into contact witht the vehicle side (7a) is a pressure-sensitive switch strip (13), halting the sliding movement of the plate on touching the vehicle. The leading edges of the strip which does so can be of elastic material, typically a liquid-filled hose connected to a control switch.

Title: Water jet drive for fast boat - with effectively constant area duct and central impeller leading water upward
Inventor: ECKES HEINZ
IPC: B63H11/04
Filed: 1975-06-05
Abstract: The waterjet boat ahs an intake grille under the hull, with horizontal and vertical grilles to prevent ingress of debris. A ducted guide leads the waterstream upwards to an impeller mounted in the centre of the guide so that the water flows between it and the walls. The output side of the impeller is tapered so that the effective cross sectional area remains constant, thus reducing the risk of cavitation and instability. For a balanced thrust two waterjet systems are mounted side by side in the boat.

Title: Reactor guiding of fuel elements and cruciform control rods - with plates fixed to fuel elements sliding on vertical bars
Inventor: BORRMAN BO
IPC: G21C5/06
Filed: 1975-06-14
Abstract: The parent Patent describes a core grid mounted above the core, in which each division of the lattice contains four independently removable fuel boxes each containing a cluster of rods and each resiliently mounted relative to the arms of the grid and each other; the gaps between the four fuel boxes contain a control rod of cruciform section, and the fuel boxes are guided at grid level by guide plates rigidly attached to them and sliding on guide bars rigidly attached to the grid. In the Parent of Addition, each guide plate has a blocking surface oriented perpendicularly to the fuel box face and co-operating with the guide bar. The position of this guide bar relative to the grid can pref. be adjusted by screws, so that the distance from face of guide bar to centre-line of lattice division is adjustable. Improved safety against faulty angular positioning of a control rod, e.g. resulting from an earthquake or from fuel element changing. Faulty control rod positioning could lead to jamming.

Title: Mortice lock for tubular framed door - has lock catch with actuating mechanism with jamming tumbler pin
Inventor: KOTTERHEID GUENTER
IPC: E05B63/00
Filed: 1975-06-19
Abstract: Mortice lock for tubular door frames has a locking catch which projects beyond the lock edge plate. Lock is actuated by a key or a locking cylinder and has small dimensions with relatively large lock catch travel. The locking element fitting opening is arranged on an actuating lever whose section between the pivot point and locking element fitting opening is coupled with a transmission lever.

The actuating lever carries a tumbler pin which limits the number of rotations of the lock actuators. This pin is held in a slot with edge shape for wedging this pin when the lock catch is extended for locking.

Title: Coke oven door seal - with angle iron deflected by thrust bolts and supported by metal blocks and flat strip
Inventor: HERRMANN ERNST
IPC: C10B25/16
Filed: 1975-08-01
Abstract: The coke oven door carries around its periphery a flange which serves as the seat for the flat flange of a sealing strip angle. Sets of screws locate the flange and a second set of screws is applied to the web of the angle which is pressed with its sharp edge against the door frame. Metal blocks and a flat steel strip structure fill out half the depth of the angle iron frame. This is a simple design, yet it compensates any possible irregularities in the sealing faces of door and door frame. The depth of all grooves is such that conventional cleaning machinery can readily deal with them.

Title: Room air curtain control - using position, direction and section of discharge or intake apertures which adjusts to ambient conditions and certain length
Inventor: MUELLER WOLFGANG
IPC: F24F9/00
Filed: 1976-01-08
Abstract: Air curtain control with discharge apertures governs the air flow by adjusting the air entering by position, direction attitude and size of the discharge apertures, and/or the direction, intensity and/or guidance of the issuing air at the aperture. It is also possible to control the curtain by adjusting the intake air flow by position, alignment attitude and shape or section of the intake aperture and/or the direction, intensity and/or guidance of the intake air flow. The control should adapt automatically to ambient conditions and it should be possible to vary the depth of the air curtain in the room or enclosure on the entry side, or on the intake grid, by throttle or baffle to suit the distance to be covered by the curtain and the ambient conditions.

Abstract: In the production of pure-4-dimethylamino-phenol (I), 4-amino-anisole (II) is treated in weakly alkaline aqueous solution with dimethyl sulphate to give N-(4-methoxyphenyl)-N,N,N-trimethylammonium methylsulphate (III) in quantitative yield; (III) is isolated by crystallization from aqueous solution and subsequently converted into 4-di-methlamino-anisole (IV) in practically quantitative yield by heating with concentrated alkali hydroxide at normal pressure. The (IV) pptd. in solid form is converted into (I) hydrohalide by boiling in aq. hydrobromic acid or by heating in highly concentrated hydrochloric acid under pressure. (I) is useful as an antidote for hydrogen cyanide poisoning. It is simple process giving pure (I) in very high yield (overally yield ca. 80%) from inexpensive raw materials and reagents. In an example, (II) is reacted with dimethyl sulphate in aq. NaHCO3 to give (III) in 97-100% yield, and this is boiled 2-2.5 hrs. with aq. NaOH to give (IV), which is subsequently refluxed 8-9 hrs. with aq. 62% HBr to give (I). Overall yield for the first two steps of the process is 88-91%, while yield for the final step is 92.8-93.5%.

Title: Film etching process for use in integrated circuit mfr. etc. - uses ion beam monitored by electrical property measurement of reference specimen in same vacuum chamber
Inventor: KUHLMANN-SCHAEFER WILHELM
IPC: H01L21/66
Filed: 1976-11-10
Abstract: A method for the etching of layers of a body, e.g. film or parts of films in the mfr. of integrated circuits, is based on bombardment with ion beams and supervision of the eroded thickness. The change of one or several electric properties of the body during the etching is monitored and is used to determine the depth of erosion. This supervises the depth of etching with an accuracy of 50 angstroms. It requires less appts. and is more economical than using a mass spectrograph. The result is a structure of better smoothness and fineness.
