Patent DE-2432208-A1 (DE)
Title: Automated guidance for rail trolleys - with magnetic sensors to move lateral guidance rollers into guide rails
Inventor: HARTUNG HEINZ
IPC: B61F9/00
Filed: 1974-07-05
Abstract: The tramcar of railway trolley is powered automatically on electric pick-up tracks and is guided by lateral guides which are engaged by lateral rollers. The rollers are coupled to linkage attached to the floor directed magnets under the trolley so that when the trolley has to change tracks the magnet moves the linkage. This moves the rollers into the appropriate guide rail so that a fully automatic guidance can be achieved over a grid. The magnets are electromagnets which are remotely operated via electric motors from a central control.

Inventor: HOSTA PUJOL
IPC: C07C59/70
Filed: 1974-08-14
Abstract: New esters are cpds. of formula (I): (where R is t.-butyl, p-chlorophenoxymethyl, 3,4-dimethoxybenzyl, 3,4,5-trimethoxyphenyl, benzhydryl or alpha-(p-chlorophenoxy)-alpha, alpha-dimethylmethyl), which may be prepd. by reacting DL-alpha-tocopherol with an anhydride of R-COOH in an inert solvent and a high-boiling anhydride in the presence of zinc and in a nitrogen atmos. In various experimental animals (e.g., flies and rats) the esters (I) markedly increase the mean lifetime, and are therefore suitable for use in geriatrics.

Title: Refractory material for drains or troughs for steel pouring - contg. fused silica with addition of carbon and silicon
Inventor: PAUL OSKAR DR ING
IPC: C04B35/14
Filed: 1974-08-29
Abstract: Refractory ceramic material produced by fusing fine granular silica (1 mm), for use as submerged drains, troughs or other devices for pouring molten steel, is improved in that it contains 5-30 wt. % of carbon (graphite, carbon black, pitch), and up to 20 wt. % of silicon in the form of fine grains. Graphite content should be relatively high if increased heat conductivity is desirable. The compsn. may contain 1-10% of an organic pressing aid, such as tar, tar-distillate, bitumen, dextrin, polyhydric alcohols, sulphite lye or stearates. This compsn. has better pressing properties than the known compsns; isostatic pressing can be applied; the firing temp. is lowered; the process conditions are not critical; the erosion of the product by molten steel is reduced; the materials are cheap; the porosity and permeability of the material can be reduced by impregnation with a silica sol.
Patent DE-2441654-A1 (DE)
Title: Audio tape-recorder partic for film projectors - has second erase head following record and playback head
Inventor: PFAFFINGER SIGFRIED
IPC: G11B5/024
Filed: 1974-08-30
Abstract: The magnetic sound recording and playback arrangement is for use particularly in sound film projectors and has a second erase head (9) in addition to that (6) which precedes the record and playback head (3) as is conventional.

The second erase head can be connected by means of a switch (10) to a high frequency generator (8) which is linked also to the first erase head (6) through a switch (7).
Patent DE-2445845-A1 (DE)
Title: Automatic programmed tariff changer for telephone exchanges - allows changes of tariff throughout day at half hourly intervals
IPC: H04M15/10
Filed: 1974-09-25
Abstract: A time encoding system with an associated dial-shaped setting mechanism is presented, which allows automatic changes in tariff rates to occur at half hourly intervals if required at a telephone exchange. The rates charged are dependent on a clock rate which is fixed by the distance being called and by the device described, one of which is associated at the exchange with each distance dependent clock generator. A control timing unit produces a pulse accurately every half hour, and an electronic encoder accumulates this information in 48 bits in a very redundant but reliable code, so that each half hour module is identifiable at a coded output. This in turn drives a dial shaped device which allows various set points to be chosen at which changes can be made.
Patent DE-2446642-A1 (DE)
Title: Steam cooled reactor esp. of ship propulsion - in which variable proportion of superheated steam is injected into water
Inventor: NAKANISHI TETSUICHIRO
IPC: G21C1/08
Filed: 1974-09-30
Abstract: A steam-cooled nuclear reactor comprises a core contained in a pressure vessel and supplying its heat for superheating steam to drive turbines, esp. for ship propulsion. The ascending, heated steam leaves the core through a number of ducts and is collected in a header above the core; from here, the steam flows through a header and sub-divided into two flows; the principal flow leaves through vessel outlet ducts and passes to the steam turbines, while a secondary flow passes downwards through a series of ducts, each terminating in a nozzle submerged in a tank of water surrounding the core but separated from it by shields, this steam injection evaporates part of the water, producing saturated steam which ascends in the vessel, passes through a screen dryer into the top dome of the vessel and is drawn from there by intakes leading to circulating pumps from which the steam is returned through coaxial inner ducts to a saturated steam header above the core; from this header, each downward saturated steam duct is coaxial and outside the ascending superheated steam duct, so that the descending saturated steam is dried before it enters the core. The high thermal efficiency of a steam cooled reactor circuit is obtained. No damp steam enters the core. Wide variations in turbine load, requiring widely varying supply rates of steam to the turbine, can be accommodated by modifying the amount of steam passed to the turbines and compensating it by the amount injected into the water tank. During shut-down it is possible to maintain the required temp. in the various parts of the sector.

Title: Conveyor plant with driven trucks - switch elements form active and passive parts of contact-free signal transmitter
Inventor: KARDINAL HANS-JOACHIM
IPC: B61B13/00
Filed: 1975-04-15
Abstract: The conveyor plant has driven trucks running on defined lines, with an electric motor and switch element at both front faces. When two trucks approach each other, the switch elements interrupt the drive circuit of the motor on the rear truck. The switch elements form the active (M11, 12) and the passive (M11, 12) parts of a contact-free signal transmitter. This is formed and dimensioned, so that the minimum distance (w) to the active part of a neighboring truck (W1, W2), necessary for the passive part to react, is the same size as the over-run of the trucks, after its drive circuit has been interrupted. The passive part has pronounced hysteresis-characteristics. The active part of the signal transmitter is formed as a magnetic assembly. The passive part is formed as a directly magnetizeable contact arrangement.
