Title: Cartridge for fast loading automatic weapons - has firmly held priming charge to prevent dislodging during loading
Inventor: KOENICKE HELMUT
IPC: F42B5/26
Filed: 1974-04-29
Abstract: A cartridge for automatic weapons, esp. where high acceleration and deceleration forces occur during loading, has a cavity for an ignition capsule on the firing pin side, sepd. by the base of the cartridge itself from the priming charge on the other side, which is contained in a space adjacent to the main charge. The communication between the two cavities is by an ignition duct. Pref. the priming charge cavity has a grooved inner surface; this is used esp. where the priming charge is a solid (cemented) block. The block may be contained in a sleeve package. Used esp. for short cartridges with a dia./length ratio >1/3. The priming charge does not come loose, avoiding mixing with the main charge, and/or non-uniform detonation.

Title: Inertia forces compensator for crank press - uses coupled weights for compensating vertical and horizontal force components
Inventor: BILZ HERBERT
IPC: B30B15/00
Filed: 1974-07-17
Abstract: The weight compensating device is used especially in presses with variable stroke length. Such a press has a crank driven reciprocating ram and the balancing masses compensate the inertia forces generated by the re ciprocating movement of the ram and of the connecting rod. The balancing masses compensate horizontal and vertical components of these inertia forces. This balancing arrangement has no driven elements connected to the machine power system. It is highly compact and it generates little noise. The balancing masses (30, 30') are arranged on rotating levers (24, 26) which rotate about a fixed common axis (22) which is at right angles to the travelling direction of the ram (10). The balancing weights are connected to the connecting rod (18) and the ram by a connecting linkage which enables these masses to carry out relative movements to the connecting rod and the ram.
Patent DE-2447974-A1 (DE)
Title: Discharge X-ray apparatus with decoder - has a device showing its incorrect adjustment in accordance with the KV and MAS control
Inventor: NIEDERMAYER HANS DIPL ING
IPC: H05G1/26
Filed: 1974-10-08
Abstract: Signal values are collected from the controls and applied to a decoder which operates close enough to a specified relation between various parameters. A maximum discharge value is set on this decoder, which can deliver a signal for blackening admissibility of the set adjustment. Control for kV and mAs are logarithmically calibrated, while pickups for these controls deliver linear signal values, e.g., voltages, so that their value difference gives a direct measure for the expected discharge, thus being directly comparable with the maximum permissible discharge value. It delivers a signal when this value is reached or exceeded.

Title: Unalloyed or low alloy steels with low carbon content - with greatly improved strength obtd. by quenching after hot-rolling
Inventor: SCHMITT WOLFGANG DIPL ING
IPC: C21D8/08
Filed: 1975-05-31
Abstract: The steels contain max. 0.35% C, and have an end temp. on leaving the hot rolling mill >= the Ar3 temp.; they are directly cooled in >=1 stage at a min. rate of 200 degrees C/second to below the Mfr point which is normally below 200 degrees C. and in the range 600-500 degrees C. they are cooled at a rate above 500 degrees C/s. After completing this hardening operation the steel is tempered to obtain a martensitic matrix consisting of martensite with a high dislocation density. The tempering operation may be carried out by the user of the steel at a date subsequent to that when the steel was hardened and, in the case of steel for pre-stressed concrete, a short-time tempering cycle can be combined with the thermal pre-stressing of the steel. In addn. to use in pre-stressed concrete, this steel is suitable for springs, high-tensile structural purposes, and agricultural machinery including sieves used in potato harvesters.

Title: Ballast for forklifts or counterweights of other machines - produced from particulate waste material and resinous binder
Inventor: KREITNER LUDWIG
IPC: B66C23/74
Filed: 1975-09-30
Abstract: The ballast or counterweights for vertically moving mechanisms is formed from a heavy waste material (pref. iron or steel shot or turnings) and a resinous binder (cold-hardening resins). The waste material is comminuted and densified, if necessary, and the particles are coated with the resinous binder. The material is then introduced into a mould pref. made of iron sheet or cast iron, which will subsequently serve as a permanent housing for the ballast. After the binder has set, the pores between the particles are filled (under vacuum or with applications of hydraulic press.) with a spontaneously solidifying liquid, such as water glass or a soln. of an epoxy resin or polyester or polyacrylate. This liquid may contain a weighting additive, such as cement or The ballast has high density so that space is saved and, in the case of a forklift, the centre of gravity is situated as low as possible. The ballast has sufficient mechanical strength, esp. impact resistance. The price is relatively low.

Title: Switching circuit allows LV AC vacuum switch to switch DC load - using relay to control thyristor in series with capacitor across vacuum switch
Inventor: GEBAUER ECKEHARD DIPL ING
IPC: H01H33/59
Filed: 1976-02-28
Abstract: The switching circuit allows LV AC vacuum switches to be used for switching DC loads. The vacuum switch (2) is connected in series with the load (1) across the d.c. supply and is shunted by the series combination of a capacitor (3) and thyristor (5).
