Title: Copper exchanged type y zeolites - for olefin-paraffin separations
Inventor: ROSBACK DONALD HERBERT
IPC: C10G25/03
Filed: 1972-04-07
Abstract: Type-Y zeolites may be copper exchange to make them suitable for use in processes for the sepn. of olefins from paraffins, such as in products from dehydrogenation of n-paraffins. Process comprises treating a sodium form Type-Y zeolite with aq. soln. of water-soluble copper salt at 15-250 degrees C to exchange at least part of the Na ions, heating at 100-550 degrees C to at least partially dehydrate zeolite, and contacting with cuprous salt and a hydrocarbon (pref. olefin) such that a soluble complex is formed which may enter the pores of the zeolite at elevated temps. The normal polymerisation and isomerisation activity of copper exchanged zeolites are suppressed by the cuprous salt-hydrocarbon treatment stage.

Title: Centrifugal separator for dust laden exhaust gases - with provision for cold air injection and water cooling
Inventor: SCHLEWITZ ARMIN
IPC: B01D45/16
Filed: 1972-10-10
Abstract: The centrifugal effect is enhanced by injecting air from rotation inducing jets. The separator is in two stages, the first have a spiral central swirler at the base of which are mounted the first air jets. This effects coarse separation. The gas rises through a central duct and then down through second stage separators with a second set of air jets in the centre which gives fine separation. The dust collects at the bottom and the by now cooled gas rises up a central tube. With a typical entry temp. of 800 degrees C, the gas leaves at about 300 degrees C. The whole is surrounded by a water jacket.

Patent DE-2341438-A1 (DE)
Title: Simple layout antiblocking brake control - using wheel speed impulses to hold off brake vent valve powered by brake light current
Inventor: HORNSCHEIDT DIETMAR
IPC: B60T8/42
Filed: 1973-08-16
Abstract: The brakes are vented by an electromagnetic valve which is powered by the brake light current, to which it is connected in parallel. The current holds the valve in the 'off' setting via a capacitor. A wheel speed impulse generator provides a train of impulses to charge the capacitor, and when these impulses disappear, and the wheel locks, the electromagnetic valve operates rapidly and closes off the brake line, and vents the return line. The brakes are then rapidly released. The system is simple in design and is readily fitted to all vehicles.
Patent DE-2358704-A1 (DE)
Title: Rack type steering mechanism for motor vehicles - has a toothed disc under clamping ring for locking tubular column to housing
Inventor: WALTER WOLFGANG DIPL ING

Title: Illuminated fish-enticer for sea-angling - consists of chrome-plated tube with battery-operated bulb inside and red or yellow eyes
Inventor: KNOCHENHAUER RICHARD
IPC: A01K85/01
Filed: 1974-02-27
Abstract: The fish-enticer is stuck in a chrome-plated tube facing red or yellow eyes. The tube also contains a bulb which is operated by a torch battery of, for instance, 1.5 Volts. The red or yellow rays attract the sea-fish when in total darkness at great depth. The fish-enticer can be made in any size and fitted with larger batteries. The device is assembled for operation by undoing a screw at the bottom and taking out the cap with the end-price. The battery-holder then slides out. The rubber and stoppers are removed, and the battery inserted. The sealer-cap and the spacer-sleeve are made of plastic.

Title: Ammunition testing artillery gun recoil mechanism - has propellant charge and number of water filled containers
Inventor: RATHMANN GERHARD
IPC: F42B8/04
Filed: 1974-07-01
Abstract: This ammunition, used for the development, testing and acceptance of new guns and on reconditioning work of guns tests the functioning of the recoiling components and of the restorer. It enables the guns to be readily tested under workshop conditions, hence eliminating the need for transport to suitably equipped proving grounds. The ammunition can be used also for testing of guns of armoured vehicles. The containers for water have filling openings with closing plugs. The end faces of these containers are formed so that they can be connected end to end. The gap between the end faces when in the gun barrel is very small over the whole cross section of the gun barrel bore. The containers each have an external screw thread at their ends by means of which they are screwed together using a round connecting sleeve.

Title: Ejector jet mixing chains - on central heating systems to optimise pressure and temp. for recycle mixing
Inventor: STREMPEL ERICH
IPC: B01F5/04
Filed: 1974-07-04
Abstract: Controllable mixing device using jet ejectors to mix hotter and cooler liquids consists of two or more ejectors connected in series behind each other, each forming a pressure stage, in which in the region of reduced pressure the mixing temp. is reduced so that no evaporation occurs. The cooler liquid enters either through a mixing line into the ejector suction of each or only of those at the lower pressure stages, in which case the outlet from one ejector is connected to the suction of the next but one. In these mixing lines pumps are located which can have individual or common drives. Esp. for use with central heating systems. The system reduces the energy required to obtain the mixing needed for precise temp. control. It also avoids the possibility of cavitation in the mixer. By introducing some cool liquid at lower pressure stages, not all the pumps need to have the full head.

Patent DE-2443797-A1 (DE)
Title: Automatic anhydrite wetting control - by pressure sensor actuating metering valve of liquid activator in anhydrite pipeline
Inventor: SCHROER DIETHELM ING GRAD
IPC: B65G53/66
Filed: 1974-09-13
Abstract: In pneumatic transport systems for anhydrite, used in building road packs along the gates in coal mines a liquid activator has to be added in the pipeline through a wetting nozzle. The pressure immediately upstream of this nozzle is picked up, amplified and used to control a servo drive for the metering valve on the nozzle through a logic transducer. This is more accurate than manual control of the metering valve and eliminates the time lag between control action and emergence of the wetted anhydrite at the discharge end.

Title: Regulating heat circulation of hot water central heating - uses return water mixed with the delivery water in relation to room or outside temp.
Inventor: BENZINGER SIEGFRIED
IPC: F24D10/00
Filed: 1974-11-05
Abstract: Both the return and delivery temperatures are monitored and the mean water temperature of the system, corresponding to the logarithmic mean of the delivery and return temperatures, is regulated, thus preventing overheating of rooms. When the return temperature exceeds a certain value in relation to a given delivery temperature, the amount of return water added to the delivery water through the blending valve is increased. The return and delivery pipes can be connected, to allow all the return water into the delivery pipe when a given return temperature is reached.
