Title: Shaft speed reduction gearing - uses bevelled cup gears and roller cam fixed to drive shaft
Inventor: MUELLERSCHOEN JUERGEN ING GRAD
IPC: F16H1/32
Filed: 1975-05-07
Abstract: The step-down bevel gear is connected to a normal crown gearwheel (7) and cup spring (3) with a roller cam plate (1). The roller cam is attached to a fast-rotating drive shaft (2) and slides or rolls against a fixed cup spring (3). The cup spring is attached to bolt (5), and has a toothed face (4). The number of teeth differs from that of the opposite toothed face (6) of the driven shaft (7). The speed reduction depends on the ratio between the numbers of teeth on the driving and driven shaft. Usually the difference in number if very small, may be only one tooth. The ratio may equally well be stepped up, as down.

Title: Electric vehicle lead battery - has gas filled balls of electrolyte resisting material in gas compartment to reduce explosion hazard
IPC: H01M10/52
Filed: 1976-02-27
Abstract: The cells of the lead battery for electric vehicles are partially filled with electrolyte (6), the remaining space (7) collecting the reaction gas from water decomposition. The risk of explosion is reduced by filling the available volume over the electrolyte with plastics balls(8) with a preferable range of diameters between 10 and 15 mm. In addition, the plastics balls(8) restrain the movement of the electrolyte, and thus offers a protection against splashes. The balls also restrict the evaporation of the electrolyte leading to longer periods between topping up with water.

Title: Car warning generator using radio - with broadband generator responsive to other cars horn to overcome sound insulation of car body
Inventor: SADLER WILLIAM S
IPC: H04H20/62
Filed: 1976-03-29
Abstract: The warning generator produces a whistle or other sound on a car radio in response to the sound of the horn of another car. A broadband signal generator (11) is coupled via a BP shaping filter (13) to a modulator (15). The modulator modulates the roadband signal with the output of an oscillator (17) whose frequency lies in the radio band and which is controlled by the receipt of an audio signal. The modulator output is used to modulate a carrier-wave (21) which is then BP filtered and amplified to produce the interference signal. This signal is transmitted to produce the warning tone on other car radios.

Title: Welded shutter for hot blast valves - where outer ring is shrunk onto discs to form lap joints prior to welding
Inventor: UERLICHS JOHANNES
IPC: B23K9/00
Filed: 1976-06-23
Abstract: A ring weld is made between two workpieces, esp. two ring weld made between the two legs of a U-shaped ring and two circular discs in the mfr. of a sliding shutter used in a valve on a hot wind duct, e.g. in a blast furnace plant. Radial overlapping is provided for both joints, and the ring is heated before assembly so its radial expansion slightly exceeds the radial overlap. The ring is then pushed over the two discs and cooled to form the lap joints at the seams which will be welded. Instead of heating the ring, the two discs may be cooled before assembly. The ring is then pushed over the discs and the correct lap joint are obtd. when the discs return to room temp. Used for welding metal parts together to make a sliding shutter. The parts are correctly aligned and centered prior to welding, and a base is provided at the root of the welds by the lap joints, so strong welds are obtd.

Title: Control device for NC machine tool - has a computer controlling speed, acceleration and braking of drives for machine tool feed axes
Inventor: GOSE HORST DIPL ING
IPC: G05B19/416
Filed: 1976-09-24
Abstract: A computer derives from input signals at specified control intervals nominal values for position control circuits. These control circuits in turn produce nominal values for speed control circuits of drives allocated to the machine tool feed axes. The computer (2) comprises a computing unit (9) and a process rate control logic unit (10). The computing unit (9) calculates for each control interval discrete acceleration values, discrete speed values and travelled distance increments from input signals for acceleration, nominal speed and total distance travelled. The process rate control logic unit (10) generates a brake command for a whole control interval, depending on the acceleration, speed and remaining travel. This time interval is the one into which the exact starting point for braking falls. The braking process is so controlled until a switching off threshold speed is reached, that in at least one control interval the braking command is switched off and the operation carried out at constant speed, provided the ideal braking parabola is not exceeded.

Title: Measuring device for properties of suspended particles - has medium flow path to measurement orifice which narrows differently in two orthogonal planes
Inventor: KORDWIG ERNST
IPC: G01N15/14
Filed: 1976-12-11
Abstract: The device for measuring certain properties of particles suspended in a medium has a narrowing flow path ending in a hole which the medium flows owing to a pressure difference. The particles are fed through a capillary tube ending in an exit hole, and carried by the medium flow to a measurement point. The flow path up to the hole (103), which can be of any cross section, narrows at different rates, in two planes (x/z plane, y/z plane). The ratio (A/a, B/b) of the liquid flow width (A, B) at the particle suspension entry point to the hole width (a, b) is different in the two planes.
