Patent DE-2544696-A1 (DE)
Title: Computer controlled knitting loom input-output device - with keyboards for operator to machine dialogue and program card
Inventor: DILL PETER DIPL ING
IPC: D04B15/66
Filed: 1975-10-06
Abstract: The input-output equipment for an electronic data processing system of a knitting loom includes a control panel for the dialogue of the operator with the computer when one of the peripheral appliances is connected. This panel contains all input keys and display unitss for all knitting patterns. This requires only one input/output equipment to feed the necessary colour and ancillary data into the computer memory. A program card on the control panel which can be written in any language eases the work of the operator more than an image on a screen.

Title: Identification of code sign in pulse stream - is for single or multifrequency pulse code modulated systems
Inventor: HAJNIK PAVEL
IPC: H04Q11/04
Filed: 1976-05-12
Abstract: The circuit provides identification of single or multifrequency code signs arriving as a pulse code modulated signal stream. The incoming pulse code modulated words are individually stored in a memory system for each time division in each of 'K' frames or pulses. Read in and read out is initiated by the first word in the (K+1)th frame of pulses. The values of the first and last and second and last but one frames and so on are added and/or subtracted to form partial resultants, each such being multiplied for each of 'N' frequencies. Even and odd pairs are summed separately, the output appearing as the root of the square of the sums for each particular frequency.

Title: Sweeper for settling ponds - having pressure sensor which adjusts the height of sweeper above the base to prevent jamming
Inventor: WEBER WILHELM
IPC: B01D21/18
Filed: 1977-04-21
Abstract: Sweeper system for settling ponds has a sweeper device which is mounted on a carriage above the pond with pusher or suction device. Its height can be adjusted by a positioner. It has a detector to measure the liquid pressure which is connected to the positioner. If the pressure exceeds a specified value, the sweeper is raised to the next position. This continues until the pressure is at the desired value. Between two positioner impulses of the sensor an adjustable time is established during which contact between the sensor and the positioner is broken. The pressure range on the sensors can be adjusted. System is for clearing out settling ponds such as sand settlers, thickeners etc. Avoids the problem of many sweepers that follow a wavy path over the sludge bed due to pressure variations. The sweeper is less prone to upsets and has general application to all types of pond and settler.
Patent DE-2718112-A1 (DE)
Title: String post for musical instrument - has constant taper from head to curved increasing dia. shoulder at post base
Inventor: FENDER CLARENCE LEO
IPC: G10D3/12
Filed: 1977-04-22
Abstract: The spring post has a constantly decreasing diameter from the outer end to a first plane closely adjacent the instrument head and has an increasing diameter from the first plane to a second plane at the instrument head. This forms a curved shoulder at the base of the post between the first and second planes. This construction urges a string wrapped around such a string post toward the instrument head until the last wrap seats against the shoulder at the base of the post, virtually in contact with the instrument head. The string post also reduces the ability of the string to vibrate relative to the nut, substantially increasing the tone sustaining capabilities of each string.

Title: Uranium di:oxide prodn. with regulated properties and fluoride content - by varying hydrogen throughput in redn. and time of pyro:hydrolysis
Inventor: JENCZIO ULRICH
IPC: C01G43/025
Filed: 1977-06-06
Abstract: In the prodn. of UO2 with pyrohydrolysis, as in the parent patent, in which the H2, from the redn. treatment is removed as far as possible before pyrohydrolysis for is not 45 min. at >650 degrees C, the H2 throughput per unit time in redn. and the pyrolysis time are used to regulate the residual F content and the properties of the nuclear fuel pellets produced from the UO2 powder. UO2 powders with the required specific surface area, bulk density, F content and sintered density can be produced. E.G., redn. of the amt. of H2 or other reducing gas causes a redn. in the F content, specific surface are and sintered density and an increase in the bulk density.

Title: Heat pump driven by diesel engine - uses waste heat of exhaust to preheat source and condenses pollutants out of exhaust
Inventor: CREDE HELFRIED
IPC: F02D41/30
Filed: 1977-10-04
Abstract: A heat pump for domestic heating has an evaporator in a pool of outdoor water and a condenser in a warm air duct which provides heating to the building. The compressor of the heat pump is driven by a diesel engine. The exhaust of the diesel engine passes through a heat exchanger in the outdoor pool. This raises the temp. of the source and cools the exhaust. The exhaust can then flow through a further heat exchanger in which it preheats the refrigerant condensate. The performance of the heat pump is improved and polluting constituents of the exhaust are condensed out of it.
