Title: Airflow control flap for car heater - with rotating half cylindrical shutter and half cylindrical warm and cold air ducts
Inventor: KOEHLER REINHARD ING GRAD
IPC: F24F11/02
Filed: 1974-11-22
Abstract: Thefresh air system for the car has seprate warm and cold air ducts which meet at a blower which blows the air through selected outlet ducts. To ensure an even airflow resistance over a range of relative settings of the two flows, they are arranged side by side as half cylindrical ducts. A rotating half cylindrical shutter (20) is pivoted in front of the ducts and as it turns it progressively alters the ratio of the two duct cross sections. The air mixing is completed by the blower to provide an even temperature output. The sytem operates smoothly from fully cold to fully warm, with only a simple control linkage (23, 24) required.

Title: Hoist loading skip with flat bottom - turns during lifting for bottom discharging via angled gate
Inventor: KRUPPA GUENTER K DIPL ING
IPC: B66B17/08
Filed: 1975-02-01
Abstract: The skip is flat bottomed with side rollers and an angled discharge gate at one end. A rope drive moves the skip on tracks. At the lower station the skip lies horizontal for filling. After take-off it turns by guidance of the track travelling to the upper station in the discharging position. Roller opens the gate at the chute. Across the skip's open top, bar grilling deflects the contents during filling, to spread the loading, and retains the contents after turning. The advantage of flat bottom filling and funnel bottom discharge are combined.

Title: Easily attached fastener securing buttons to textiles - comprises support plate with plastics shaft thread and transverse needle
Inventor: SPIESS OTTO GERALD
IPC: A44B1/18
Filed: 1975-03-03
Abstract: The button fastener for textiles comprises a plate with a hole which is notched at two or more points round its edge, wherein a plastics thread stems from the plate and is fastened at its free end to the middle of a plastics needle. The needle is passed through the back of the textile and through a hole in the button and then back through another hole in the button, through the cloth and then through the hole in the plate. In the case of a normal button the fastening is now secure since the needle serves as a transverse holding pin.

Title: Structural plates capable of absorbing neutrons - made from boron minerals and calcium sulphate binder
Inventor: NEUHAUSER GERHARD DR
IPC: G21F1/04
Filed: 1975-03-24
Abstract: Prodn. of structural plates capable of absorbing neutrons by mixing a calcium sulphate binder, a boron cpd. and water, moulding the mixt. and hardening, is improved by using (in an amt. of 10-60 wt.% w.r.t. the dry mixt), a scantily soluble boron mineral, pref. colemanite, pandermite, priceite, ascharite, boracite, hydroboracite or datolite, ground to the same particle size as the calcium sulphate binder. Large quantities of boron-contg. minerals can be combined with calcium sulphate binders without significantly affecting the mechanical strength and other valuable properties of calcium sulphate-base plates. The plates can be easily dried. The boron minerals act as binding accelerators. The plates are not brittle.

Title: Roller door unrolling prevention locking mechanism - with flywheel scanner linked locking latch assuming stable position when locked
Inventor: SCHULIN KLAUS
IPC: E06B9/84
Filed: 1975-05-02
Abstract: The device limits the rate of revolution of a rotatable component, esp. for preventing a roller door from unrolling. It comprises a ratchet wheel (6) coupled to this component, and working in conjunction with a locking-latch, set in the unlocking position with the rotatable component revolution rate below a critical speed.

Title: Station air mover for air driven high speed underground railway - uses heat and cooling elements forming boundary layer as turbulent air curtain circuit
Inventor: HELM AXEL-GUENTHER DR RER NAT
IPC: E21F1/00
Filed: 1975-05-06
Abstract: The air movers for use in tunnels e.g. for high speed inter-city rail stations receive their fresh air and remove the spent air through intake and outlet shafts in normal way and are fitted with thermal and cooling elements which direct the air flow and maintain this direction of flow throughout the operation. The air movers produce a self-contained circuit of boundary air without the use of locks etc to close off still-air zones and in this way form a turbulent air curtain (16) between the air layers requiring to be held apart, using conventional mechanical and aerodynamic (17, 18) systems to maintain this. The air flow in the tunnel should be held at optimum level with the aid of measuring and regulating instruments.

Title: Cooled compact operating theatre light - is cooled internally by evaporation of solid carbon dioxide in cartridge form
Inventor: ILZIG KARL F DIPL ING
IPC: F21V29/00
Filed: 1975-07-23
Abstract: The lighting fitting for operating theatres has a number of lights equally spaced on a triangular pattern. The beams meet at the axis of symmetry, with the reflectors enclosed by the lighting body. The lighting fitting produces a great deal of light with efficient cooling without using sterilised air. The fitting (12) inner region is cooled by evaporation of a solid or liquid into gas. This material evaporates within the lighting fitting at a temperature below freezing point of water. The Gaseous phase is removed through a pipeline (36) which ensures that it cannot enter the room. Soldi CO2 stored in a cartridge with thermally insulated wall can be used for cooling. The conductivity of this wall is such that the heat absorbed for evaporation corresponds to the heat loss of the lamps.

Title: Distillation column for potato, fruit, corn mash - works with additional preheater permitting reduction of overall height
IPC: B01D3/00
Filed: 1975-08-29
Abstract: A column for distilling a mash of potatoes, fruit, grain, is arranged with a preheater in the line along which the mash is fed in. The mash feed line has further, a second preheater by means of which the mash is raised to a temp. at least equal to that at which it boils in the distillation column. The second preheater may be formed by a widened out section of the mash duct which is connected to a source of hot steam and may be used to inject live steam into a zone of the column. Process ensures that as soon as the mash enters the uppermost stage of the column, alcohol is driven out of it. The column height can thus be reduced by 30 to 40%.

Title: Reverse scavenging combustion chamber - has exhaust and air currents meeting prior to reaching impact wall
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1976-02-23
Abstract: Reverse scavenging combustion chamber, in which at least two combustion tubes are directed towards a reflective wall at such an angle of inclination, that the exhaust gas and air currents emerging from them meet prior to reaching the reflective wall. The combustion tubes (2, 3) arranged in the combustion chamber (1) are at approximately 90 deg. to each other, but this angular arrangement does not disturb their projection towards the chamber wall (7).
