Title: Vehicular compressed air oscillating piston compressors - have intermediary electrical drive, common cylinder containing piston work chamber
Inventor: KLAUE HERMANN DR ING
IPC: F04B45/047
Filed: 1974-11-15
Abstract: Oscillating piston compressor which has an electro-magnetic coil arrangement and an armature connected to the piston which oscillates longitudinally. The unit has two compressors (24-27) with an intermediary electrical drive (20, 22; 21, 23). These compressors comprise two piston units which are arranged one behind the other in such a manner that in the middle of the cylinder (19) a work chamber for two compressor pistons (25, 26) is available. The electrical drive can be of the alternating current type so that a changeover switch in the current circuit is not necessary. Also, the compressors can be used to produce electrical energy, and be activated by pressure gas.

Title: Stabilisers for multi-hulled sailing boats - have centreboard re-arranged to improve manoeuvrability
Inventor: PAULMANN GERRET
IPC: B63B1/12
Filed: 1975-02-26
Abstract: The devices to increase resistance to sideways movement through the water are located near the bows or on the leading hull (1) in a fixed form (1a) and at the stern or midway between the trailing hulls (2) on a vertical shaft (5) in rotatable form, combining the function of centreboard and rudder. For multi-hulls, this shaft (5) is fixed to one of the tubular struts (3) connecting the hulls, held in their turn in sleeves integral with the foam-filled plastic hulls. With trailing hulls of low underwater profile, this arrangement brings the pivotal point for turning very far forward and lowers the overall turning resistance, improving manoeuvrability.

Title: Sowing machine dropping fertilizer with seed into drills - has distributor bar of three separate sections hinged together
Inventor: DREYER HEINZ DIPL ING DR
IPC: A01C7/08
Filed: 1975-05-02
Abstract: Grain and fertilizer are held in separate hoppers. Each hopper has three separately-throttled outlets, from which an air draught carries the material through separate pipes to three distributor heads. From each distributor head seed and fertilizer are fed together through a single set of tubes to the three sections of the distributor bar, to fall together into the drills. The separate control of the hopper outlets allows the machine's working width to be reduced by one-third or two-thirds as required at the edge of the field; also the overall width of the machine can be reduced when it is to be taken on the road, by folding the hinged outer sections of the distributor bar inwards.

Title: Power supply with two rotary converters - includes DC motors and AC generators and includes electromagnetic coupler linking shaft
Inventor: WESTERMAYER WILLO DIPL ING
IPC: H02J9/06
Filed: 1975-05-15
Abstract: The power supply consists of two generators forming part of two rotary converters, one converter is the main converter, and the other the reserve converter. The main converter consists of a dc motor (2) driven from a dc rail driving the first ac generator (3) which supplies the ac load. The reserve converter consists of a dc motor/generator set (5) driven from the second ac generator (6) and charging a battery. The two generators have their shafts linked by an electromagnetic coupling. The electromagnetic coupling is controlled by the frequency and/or amplitude of the output voltage of one of the two rotary converters. The advantage lies in detecting faults in both the supply and within the converters.

IPC: E04B2/26
Filed: 1976-01-14
Abstract: The masonry building block, ready for interlocking assembly, has flat bearing surfaces, and vertical channels pref. conically shaped, for mortar filling, passing across the whole height of the block. These mortar-filling channels (2) are evenly spaced (3) and there is always half this spacing distance from the nearest outside edge of the block (1).

Title: Metallurgical furnace waste gas purification - by thermal updraught passing gases to electrostatic filters in roof structure
Inventor: THIELKER KARL-HEINZ DIPL ING
IPC: F27D17/00
Filed: 1976-06-02
Abstract: Waste gases from metallurgical furnaces are raised, mixed with the ambient air in the furnace bay, to a screened collector area in the roof apex. They reach electrostatic dust pptns. on both sides nd can pass out clean through louvres to the outside. The dust is collected and slides in ducts to the shop floor containers. This is a simple way for the efficient dust collection in metallurgical furnace installations. The thermal updraught saves mechanical fans and reduces the noise and the maintenance required. Waste gases which cannot be absorbed by a direct exhaust system during the charging and pouring operations are effectively processed.

Abstract: A construction game for use on children's playgrounds consists of vertical posts (1) which are anchored in the ground at regular spacings. The posts (1) are provided with longitudinal grooves (2). The grooves are so located that they are in line with similar grooves on neighbouring posts. Rectangular panels (3) fit between two posts such that their ends are located by the grooves (2). By placing several panels on top of one another, walls and similar partitions can be constructed. The angular layout of the partitions is governed by the number of location slots in the posts.
Patent DE-2630407-A1 (DE)
Inventor: NIMES KARL DIPL ING
IPC: H02H6/00
Filed: 1976-07-06
Abstract: In a device for monitoring the heating of an electric motor (1), the motor current from a current transformer (5) is fed via a squaring stage (6) to an analog-digital converter (7) as a value which is proportional to the square of the current, and converted there into a digital quantity. This digital quantity, and the current-independent adjustable digital quantity of an analog-digital converter (11), are input to a computer (8) according to control commands of a step switching mechanism (10), and the computer is controlled by the step switching mechanism (10) such that the digital quantity which is proportional to the square of the current is multiplied by the current-independent digital quantity, another digital quantity proportional to the square of the current is added to the product, and this cycle is repeated after the step switching mechanism is reset, until an output quantity which appears at the output of the computer (8) makes a limit stage (9) react, and thus interrupts the motor current circuit by a release device (4). In this way, the motor can be monitored for impermissible heating, in continuous operation or load alternation. If a squaring and storing computer is used, the squaring stage and a separate memory can be omitted. <IMAGE>

Title: Verification of signal from IR sensor - using data marking read by three channel IR sensor operating on different wavelengths
Inventor: HOPT RUDOLF
IPC: G07D7/00
Filed: 1976-07-13
Abstract: The identification of markings on data recordings is enhanced by using three separate infrared detector circuits operating at different wavelengths within the range. A modulated infrared sender produces signals for three transmitter fibre optic bundles. Filter stages ensure that the wave lengths cover different regions of the infrared spectrum. After passing across the markings each signals is received, filtered, demodulated and amplified. The amplified output is compared with a reference amplitude. Only when all signal comparactos produce outputs is clearance given to the identification.
