Title: Liquid filled pipeline conveying system - pre-loaded containers moved by pull units through pipe
Inventor: TSCHUCHANOW SINOWY SINOWIEWITS
IPC: B65G51/01
Filed: 1973-08-23
Abstract: The method of conveying goods in pipe lines filled with a liquid, uses preloaded containers. The liquid level within the pipe lines is maintained at a predetermined level by adding or taking away a volume of liquid at sections arranged at a fixed distance from each other and distributed over the whole length of the pipe line system. The forced movement of the loaded containers is carried out by a pull system directly attached to the containers extending within the pipe lines and covering the whole length of it. The conveyors with the endless pull system are arranged behind each other throughout the length of the pipe line with means fitted at the connecting points to separate the containers from the preceding pull element and to connect it to the succeeding one.

Title: Stereoscopic sound cine film - with horizontally divided half frames having wide separating strip for alignment
Inventor: GREGER GEORG
IPC: G03D15/00
Filed: 1974-02-08
Abstract: The sound/cine film has each frame divided into two half frames with each half frame taking one part of the stereoscopic frame for projection using polarised light. The two images are superimposed on the frame with polarisation axes at right angles, and are viewed using special polarising spectacles. The half frames are displaced by an amount equal to the sound track while the lateral width is further reduced on each side to maintain a 2:1 format. The two half frames on each frame are separated by a blank strip which is wider than the strip separating the frames. This allows some adjustment in the two optic systems to correct superimposition alignment. The system is simple to set up and has no synchronisation problems.
Patent DE-2406207-A1 (DE)
Title: Anchor bolt for blind hole in low density building material - has radially movable blades to form anchorage
Inventor: LIEBIG HEINRICH
IPC: F16B13/08
Filed: 1974-02-09
Abstract: An anchor plug such as used in aerated concrete or similar low density building material has a number of closed anchor blades. When installing the plug in a blind hole, a circular plate which carries the blades is pulled outwards by the action of the central tension bolt. A tapered distance bush forces the free blade ends outwards into the wall of the hole thus forming an anchorage which has a large contact area between plug and material. Similar results are obtained by having a number of eccentric plates carried by a shaft. With the plates in line, the shaft is inserted into the hole. The plates are then turned until they are equally spaced around the shaft and firmly anchored in the wall of the hole.

Title: Fluidised bed coal dust gasification - in reactor with secondary gasifying medium admission nozzles for carbon on slag
Inventor: SCHUEFFLER ARNULF DIPL ING DR
IPC: C10J3/46
Filed: 1974-03-08
Abstract: Coal dust is gasified in a fluidised bed with O2-contg. gasifying agents. The gas produced leaves at the top of the reactor and is passed through a waste heat boiler. The slag, which contains some residual carbon, is brought into contact with an additional stream of fresh gasifying agents for a secondary gasification, before it drops into a water bath for quenching and disposal. A much higher gasifying efficiency is obtd.; the carbon being carried away with the slag reduced to a minimum.
Patent DE-2414153-A1 (DE)
Title: Storage heater charging device - provides heat only for an average outer temperature when fully charged
Inventor: GROSSE-BRAUCKMANN HELMUT DIPL
IPC: G05D23/24
Filed: 1974-03-23
Abstract: When the atmospheric temperature falls below the average, the storage heater requires recharging in the daytime. Control voltage for daytime additional charging is derived from a voltage, a function of the outer temperature, and is further controlled by a motor driven potentiometer. This voltage is limited to a value necessary for full charging. It has a bridge circuit with a temperature sensitive resistor as the outer temperature sensor, which delivers the temperature sensitive voltage. Voltage delivered by the potentiometer wiper is limited by a Zener diode. The time period for the charging phase is restricted to a 16-hour period from (say) 0600 to 2200 hours to facilitate discharge availability during the night.
Patent DE-2425955-A1 (DE)
Title: Transport system using marked photographic copying material - has photo-material containing marked conducting lines and device to read these markings
Inventor: BARTEL SIEGFRIED DIPL ING
IPC: G03B17/14
Filed: 1974-05-30
Abstract: A method to produce markings on the rear of coiled strips of photographic copying material to allow control of strip transport by these markings uses markings separated by pref. at least two different step lengths on the photographic material. The markings are produced on one side of a continuous conducting line for one particular step length and on the other side for another particular step length. The conducting lines with the appropriate markings are embedded into the photographic emulsion carrier before the emulsion coating is given.

Where necessary the small fastening angled plate (6) can be attached to the two short angle members (8) of the angle support (5) wherein a connecting plate (9) can be provided to act as a stabilising means and prevent the pallet from collapsing.
Patent DE-2431965-A1 (DE)
Title: Electropneumatic door opener with safety circuit - has air cushion element with actuating switches
Inventor: FREY RENE
IPC: E05F15/75
Filed: 1974-07-03
Abstract: The air cushion of the system has a number of internal chambers which are separated by diaphragms. A number of the chambers are provided with switches. The air cushion is fixed as a profile into an anchoring profile and it is actuated by pressure exerted on it by the feet. The chambers of the air cushion are connected by openings and pipelines to the switching elements. When one of the air chambers is damaged then a warning circuit for producing optical signals is connected on actuation. The pressure switches DW1, DW2, DW3 are connected by pipes 16, 17, 18 to the pressure chambers of the flexible air cushion profile. An electronic circuit analyses the signal and establishes whether all three switches have responded simultaneously. In the case of a fault the electronic circuit senses this and produces an alarm signal.

Title: Knife device for meat mincing machine - with adjustment for taking-up wear and allow for regrinding
Inventor: BUCK IMMANUEL
IPC: B02C18/20
Filed: 1974-07-25
Abstract: Knife device for meat mincing machine comprises a rotating shaft on which discs are mounted, side by side. Group of knives is placed between each pair of discs, each group consists of two identical cutters with heads in the form of clamping plates. These are guided on a circular disc by two rods and two studs so that they can slide progressively, in order to take up any wear. This arrangement allows the groups of knives, all of the same dimensions and threaded one behind the other of the shaft, to be adjusted to suit the curved surface of the lower part of the mincer. The discs are threaded on an hexagonal shaft which has a shoulder at one end and a threaded portion and a nut at the other. This enables the knives and discs to be tightened against the shoulder. The method of fixing the knives is suitable for withstanding the high speed of the shaft, while the adjustment facilities allow for the taking-up of wear and for regrinding of the knives.
