Title: Firmly secured shock absorber (Buffer) e.g. for walking sticks - is composed of relatively hard rubber gripping portion and a soft, sponge like plug shaped end portion
Inventor: KUHN GOETZ-GERD PROF DR MED
IPC: A61H3/02
Filed: 1975-06-09
Abstract: A firmly secured shock absorber (buffer) that may be fitted to the lower end of walking sticks, crutches, and the like, has a gripping portion surrounding the lower end of the stick or crutch, and a ground-contacting portion of elastic material. The gripping portion consists of relatively hard material (e.g. rubber) whilst the ground-contacting portion is made of relatively soft, spongy material in the shape of a plug bonded to the gripping portion and whose lower surface constitutes the ground-contacting surface. Good shock absorption when the crutch is put vigorously on the ground, combined with outstanding nonslip characteristics. Risk of slipping is considerably reduced when crutch contacts the ground at any angle to be expected in normal use. Noiseless in use. Easy replacement of worn-out buffer.

Title: Cable operated hand throttle - using short cable totally inside car to move pressure lever against accelerator pedal
Inventor: THIEL ULRICH
IPC: G05G1/00
Filed: 1975-07-21
Abstract: The accelerator pedal (1) is fitted with a pressure lever (6) pivoted on the side of the car, to swing a pressure roller (9) against a profile cam surface (10) attached to the pedal. The lever forms part of a double scissors type of linkage operated by a short Bowden cable (12). The order end of the cable is linked to a throttle control on the steering wheel of the car. The short Bowden cable is totally inside the car, and thus requires no complex linkage through the engine compartment. It has less wearing points for possible failure. If it does break then a temporary throttle control is easily fitted using a string to pull on the pressure lever (6).

Patent DE-2548417-A1 (DE)
Inventor: RAIMER JUERGEN
IPC: B61L23/14
Filed: 1975-10-29
Abstract: In the track safety system with standardised sections through which the same kind of vehicle configurations always travel, the speed of a vehicle configuration (2) occupying a section is detected in each section (20) by means of in each case one fixed measuring device (24) and the respective braking path of the configuration to a stop is detected therefrom. Subsequently, the sections (30 to 70) lying within this braking path ahead of the section (20) occupied by the vehicle configuration are examined for any occupied reports. If an occupied report is stored in associated memories (42 to 72), the automatic stopping of the train is brought about my means of an OR circuit (29); otherwise the train moves on into the next section (30) at undiminished speed. Starting from there, the braking path which lies ahead in the direction of travel is in turn examined for stored occupied reports; this process is repeated until an occupied section is interrogated. By interrogating such a section, a braking of the vehicle configuration which is moving forward can be initiated in good time before an obstacle. <IMAGE>

Title: Steering control for airship - with vertical and horizontal thruster duct at bows contg. airscrews for stationary manoeuvring
Inventor: SCHMIDT-KLIEBER ALEXANDER
IPC: B64B1/36
Filed: 1975-11-03
Abstract: The bows of the airship have vertical, and transverse air ducts (5, 6, 7, 8) by which the airship can be manoeuvred without any airspeed over the control flaps. Similar ducts at the tail increase the control. The bows ducts can be connected to a forward facing duct (4) by which air is drawn into the system, either by an airscrew or by a ram effect when under way. The tail ducts can be operated with opposite force to turn the ship about its centre of gravity, or both sets or ducts can act together to move the ship laterally. Docking control is improved so that the ship can dock without being affected by wind.

Title: Coal breaking and crushing appts. - has lifter shelves positioned at set angle of incline on drum
Inventor: HAHN WILLIAM F
IPC: B02C17/00
Filed: 1975-12-05
Abstract: The appts. for reducing coal and other materials, includes a hollow rotatable drum having an opening to receive feed material and wall means including screening openings to discharge material of desired size. Lifter shelves are positioned on the inner surface of the wall means for lifting and dropping material within the drum as the drum is rotated. Rotor includes a rotor shaft and shaft-mounted material impacting means positioned within at least a portion of the length of the drum for impacting material dropped from the shelves. The drum drive means is connected to the drum driving it at a speed in the range of about 70% to about 95% of critical speed. The lifter shelves are positioned on the drum at predetermined angle of inclination, ranging from 0 deg. up to 70" in a direction opposite to the direction of drum rotation. This angle causes the material to drop from the selves into contact with the impacting means at or near the crest of the orbit of the impacting means when the drum is rotated at the speed which directs the material from above one side of the rotor shaft to the other side of the rotor shaft in the direction of the down running side of the rotor shaft.

Title: Collecting and cleaning emissions from coke oven batteries - via suction ducts acting at doors and transporter cowls
Inventor: STOG WILHELM ING GRAD
IPC: C10B27/04
Filed: 1976-01-02
Abstract: An arrangement for removing and cleaning the noxious emissions from a coke oven battery, escaping during charging, coking and pushing, esp. around the doors, includes a vent pipe on the cowl of the charging transporter. Suction conduits extend lengthways above the doors or both faces of the battery and collectors for the dust laden gases arising in the region of the doors are attached. A coke quenching wagon can be moved parallel to the face of the battery and this also has a cowl with a vent. Parallel to and some distance from the face of the battery an additional suction line is arranged to which the vent of the quencher wagon cowl is connected. One suction line above the doors has a number of branches to any one of which the vent of the charging wagon can be attached and all the suction lines are connected to a cleaning arrangement with an exhaust fan. The method is cheap and efficient, Only one exhaust fan is necessary for all the functions. Overloading of equipment due to explosions is prevented without auxiliary equipment.

Title: Crude pellets for reduction in rotary furnace - produced from dust contg. iron mixed with carbon source and bentonite
Inventor: YAMADA YASUTERU
IPC: C22B1/24
Filed: 1976-02-25
Abstract: dust (I) is mixed with a C-source (II) consisting of coke and/or coal comminuted to fine particles and contg. a large quantity of C having low volatility. Ratio of C no. in (I) + (II) mixt. to no. of 0-atoms bonded to Fe in (I) + (II) mixt. is 0.75-1.25. Mixt. (I) + (II) is mixed with 0.5-7 (0.8-3) wt. % (w.r.t. mixt.) of bentonite. Resulting mixt. is pelletised to form pellets having porosity 27-40%. Pellets are dried at a temp. such that C in pellets is not burned, pref. at 300 degrees C. Crude pellets can easily be reduced to metallised pellets having a high Fe content. Bentonite content and porosity >27% prevent the breaking of pellets on quick heating to 400 degrees C. Bentonite improves compressive strength of pellets.

Title: Sealing a pressurised medicament dispenser - by providing a liquid seal between the plunger and the bellows or membrane
Inventor: WAGNER WOLFGANG DR MED
IPC: A61J1/00
Filed: 1976-04-05
Abstract: The method comprises providing a liquid (esp. of higher viscosity than the medicament) between the container wall and plunger on the one hand and a pressurised membrane or bellows on the other. When a pressure equilibrium is present, traces of medicament may be expressed but none of the liquid (which may contain an indicator dye) can seep into the medicament. This arrangement allows plastics containers of this sort to be stored for longer periods (currently ca. 1/2 year).

In the second stage the metal hydroxide is converted into the corresp. metal oxide by volatilising water at 300-500 degrees C using the thermal energy produced in the nuclear-reactor. In the third stage, the metal oxide is subjected to melt electrolysis at 300-500 degrees C using mainly the electric energy produced in the first stage with addition of a minor proportion of the electric energy from the generator utilising the thermal energy of the nuclear reactor. The melt electrolysis is facilitated is a metal halide is added in a ratio oxide/halide = 1:10.
