Title: Ground compacting machine for granular strata - has combined compacting hammer and ground vibrating equipment
Inventor: FRANK ANTON DIPL-ING
IPC: E02D3/054
Filed: 1973-11-02
Abstract: The ground is compacted by the combined effect of conventional tamping and by vibrating the ground under the tamped layer of granular material. The combined compacting arrangement ensures that the ground is settled to a great depth so that the direct compacting and tamping weight need not be excessively great. This system reduces time used on compacting and the ground is stabilised to a great depth. The layer of granular material is compacted by a vertical dropped weight. This weight is actuated by a jib type excavator. The ground below the granular matter is vibrated by a conventional vibrator unit which is placed into a hole bored into the stratum under the layer of granular matter. This vibrator is also actuated by conventional building site equipment. The dropping weight and the vibrator can be supported by a common machine. The vibrator and the dropping weight can be held on ropes passed over pulleys a distance apart on the jib or the weight and the vibrator can be arranged to be coaxial in which case the dropping weight has a central hole for allowing the vibrator to pass through.

Title: Electroslag melting with consumable electrodes - auxiliary electrode forms part of the casting produced
Inventor: RABINOWITSCH WOLF I
IPC: C22B9/18
Filed: 1974-04-10
Abstract: This process uses a principal consumable electrode entering the mould from the top, and an auxiliary consumable electrode entering the mould through a hole in the mould-base, after which the mould is partly filled with slag. The current flows between the mould and the auxiliary electrode at the start of melting and is continued until a molten pool of metal is formed; when this stage has been reached (but not earlier) the principal electrode is lowered into the slag and melted.

Title: Non-contact switching control of electrical equipment - involves ultrasonic oscillator and reflecting surface and circuit has built in memory and delay
Inventor: PAPP GEORG
IPC: G08B13/16
Filed: 1975-01-08
Abstract: An ultrasonic oscillator (4, 5) generates 40 kHz signals that are bounced off a reflecting surface (8) and received by a microphone (6). If either the reflecting surface or an object between the reflector and the microphone is moved, a low frequency signal is superimposed. The amplified signal (9) is demodulated (10), the low frequency amplified (11) and demodulated (12). The generated d.c. voltae is amplified and operates a memory (15) with associated time delay (15). When used in a room, hand movement triggers the switching circuit and the memory stage and delay ensure that the light remains on for a predetermined delay. A photocell (19) blocks the switching circuit unless natural daylight falls below a specific level.
