Title: Tumbling finishing machine grinding medium return system - has screw conveyor lifting sieved material to discharge chute over machine
Inventor: REDAELLI GUISEPPE
IPC: B24B31/06
Filed: 1976-09-30
Abstract: A tumbling machine for polishing and finishing workpieces, has a handling and separating system for the grinding medium with a base (1) which is positioned alongside the machine (5) with a sieve (3) between them resting on it. This sieve connects the discharge opening (3a) of the machine with an unloading point (3b) for the finished workpieces.

Title: Liquids metered uniformly and with thorough mixing - by several piston pumps driven from annular piston in main stream
Inventor: TUELLMANN WALTER
IPC: G05D11/00
Filed: 1976-11-05
Abstract: A method and device for metering small quantities of liq. into an intermittently or continuously flowing main stream operates as follows. The main stream of aq. liq. enters the main housing, passes opt. through a filter, and then flows into an annular piston. It drives the piston and flows out from the discharge of the housing. The annular piston drives a shaft carrying an eccentric; this eccentric drives three or more metering pistons which each inject in succession a small flow of the metered liq. into the space where the main flow passes between the bottom of the housing and the cover of the annular piston housing. This results in small quantities of the metered liq. being continuously injected into the main stream through metering valves, thus producing intensive mixing of the two liquids. Pref. the small liq. is metered in a quantity of 100 cm3 in three sets of 1500 pulses of the metering pistons to 1 m2 of the main liq. stream. Pref. metered substances are phosphates or silicates; polyphosphates contg. ions of Ca, Mn or heavy metals; and water soluble nutrients for plants and soils.

Title: Semiconductor memory element of matrix form - has orthogonal parallel rows of conductors separated from substrate by insulator and having small interspaces giving capacitor effect
Inventor: KOCH RUDOLF DIPL ING
IPC: H01L27/146
Filed: 1976-11-30
Abstract: The semiconductor memory element consists of a substrate (1) of doped semi-conductor material on which is an electrically insulating film, for example of silicon dioxide.

Title: Heat-insulated camouflage material - screens military targets from radar, ultra-violet, infra-red and visible light using reflective layers
Inventor: PUSCH GUENTER DIPL ING DR
IPC: F41H3/00
Filed: 1977-11-15
Abstract: This military camouflage sheet acts as a screen to radar, infra red and ultra violet as well as visible light. It also contains pockets of air which act as heat insulation.

Title: High rated ratio current instrument transformer - divides current to be measured into two branches, one being current comparator primary used for transformer ratio setting
Inventor: FRIEDL RICHARD DR ING
IPC: H01F38/28
Filed: 1978-01-19
Abstract: The instrument transformer is intended for matching current signals to the measuring region of a measuring or protective system, thus generating a signal in a fixed ration to the measuring signal. The current to be measured is branched onto at least two conductors. One conductor forms the primary coil of an active current comparator. The current transformation ratio of the instrument transformer is determined by the product of the current dividing ration in the parallel branch system on one hand, and the coil ratio of the secondary to the primary of the current comparator. For temperature equalising of the two branches are thermally connected, possibly over additional heat bridges.
