Title: Anti vibration type tubeless tyre - with high frequency instability included to shift resonance above useful speed
Inventor: HAGL SIEGFRIED DIPL ING
IPC: B60C19/00
Filed: 1978-06-02
Abstract: The tyre design is altered to include special irregularities which cause high frequency vibrations, or resonance, above the useful speed range of the tyre. This effectively dampens the other vibrations in the tyre-suspension combination. The system provides a high speed tyre without complex wheel balancing and special suspension. The irregularities are included in the inserts or can be caused by localised vulcanisation.

Patent DE-2849076-A1 (DE)
Title: Distillation-rectification process with preheat for feedstock - and after-cooling of bottoms, counterflow heat transfer minimising temp. difference between heat source and sink
Inventor: MARKFORT DIETER DR ING
IPC: B01D3/14
Filed: 1978-11-11
Abstract: A rectification process is described in which a multicomponent liq. is partially distilled and divided into a vapour rich in the more volatile component and a liq. phase with a low concentration of the more volatile component. The process is carried out in a continuous distn. column comprising a partial reboiler, a reflux section and a condenser for the volatile component. The liq. flows into the top of the reboiler and descends against the rising flow of vapour. The vapour flows into the reflux column and is stripped of the less volatile components. At the top of this column, the vapour passes into the condensor. The column is so arranged that the reflux heat from the reflux column is removed over a temp. range corresp. to the dew-point line for the vapour phase and the reboiler heat is added over a distributed temp. range corresp. to the boiling line for the liq. The temp. difference between heat source and heat sink is consequently minimised so that the process operates with mix. efficiency with respect to energy consumption. The feed liq. is pref. preheated in a jacket surrounding the reflux column and in counterflow to its and the bottoms are removed through a jacket surrounding the reboiler section, again in counter-flow. The distn. with rectification process minimises the energy consumption.

Title: Cutter and framer for photographic transparencies - attaches upper and lower parts of frame to cut transparency at bottom vertical guide chute
Inventor: WOHLRAB JOHANN KAJETAN
IPC: G03D15/10
Filed: 1978-11-15
Abstract: The film from which the individual slides are to be made is placed in a viewing/cutting zone (20) and cut simultaneously along both transverse sides of the selected frame (35). The cut transparency then passes over an inclined plane (40) and drops freely under gravity to the place where the frame is attached. The cutter consists of two knives (24, 24') spaced by the width of a picture. The inclined transfer plane leads to a vertical guide chute (53) down which the cut transparency falls freely under gravity. A slide beneath the chute presents the lower part of the frame to the falling transparency.

Title: Speed control system for vehicle - has distance measuring radar automatically braking vehicle but capable of being overridden by accelerator pedal
Inventor: ACKERMANN FRITZ DIPL PHYS DR
IPC: B60K31/00
Filed: 1979-01-08
Abstract: The speed control system has distance measuring radar producing signals describing the distance of the vehicle from the vehicle in front. When this distance drops below a given value, the vehicle's throttle value is adjusted and the brake is operated to reduce the speed automatically. The driver can override the automatic speed control (in order to e.g. overtake) by operating the accelerator pedal. When he does this the braking is disabled by the stored given value describing min. distance between vehicles) is retained. The distance measuring equipment is also disabled beyond a given steering angle in order to prevent roadside objects along bends from affecting speed. The speed on bends is controlled by a device responding to transverse acceleration.

Title: Impeller for aerating sewage sludge - has hub with tubular vanes supporting flat ring with tangential ribs
Inventor: KUZNETSOV VYATSCHESLAV DEMYANO
IPC: C02F1/24
Filed: 1979-02-24
Abstract: A hollow hub fitted with radially projecting tubes, along the generating lines of which slot-like outlets are provided for the escape of air sucked in by the impeller, is assembled on a hollow shaft to form a device for aerating sewage sludge. On the tubes, on the side of the hollow shaft, a flat ring is assembled coaxially with the hub, leaving an annual gap. Between each pair of adjacent tubes, on the surface of the flat ring, a rib is provided which runs at a tangent to the inner edge of the ring. The end of the rib at the periphery extends into the zone of the flow from the outer ends of the tubes rotating with the impeller, in front of the ribs. Pref. the distance between the outer ends of the rib and the outlet of the tube it approaches is one fifth of the distance between the axes of the two adjacent tubes along the arc joining their ends. The outer dia. of the flat ring is the same as that of the impeller. The breadth of the ribs measured below the flat surface is three quarters of the outer dia. of the tubes. The impeller may be inclined to the hollow shaft at an angle of 75-85 degrees. This provides an aerating arrangement for dispersed solid matter in sewage in which a more intensive evacuation of the air sucked in, from between the impeller tubes, is ensured.

Title: Coolant circulation in spectacle lens grinders - using filter bag of nonwoven polyamide or polyester fabric on return side
Inventor: ALLEN EDDY
IPC: B24B55/02
Filed: 1979-04-23
Abstract: Optical lens prodn. in generating and edge grinders, is done with the aid of liq. coolant. This is constantly recirculated through the machine. A filter bag is included in the circuit, for removing particles washed away by the coolant. The bag is of non-woven polyamide or polyester fabric. Denier is 3.5-5.0 and density 0.3-2.0 ounces per sq. yard. Redn. in flow rate caused by the material is 1.0%. Used for spectacle lenses, whether of glass or plastic, using either water soluble or oil based coolant. From the start, the filter will remove 75-80% of particles under 5 mu. After a cake has built up on the filter, its efficiency will improve to the extent of removing 97-99% of all particles. Up to 600 lenses can be ground before filter placement is necessary. Time for replacement is greatly reduced.

Title: Office machine printer mechanism with improved text visibility - has forward and rear type carriers with forward window with space for rear characters to pass through
Inventor: BURKHARDT GOTTFRIED
IPC: B41J1/24
Filed: 1979-04-26
Abstract: The printer mechanism for office machines has individually operated type mounted in a circle on a motor driven carrier. Each type letter is moved against the print stop by a hammer. It minimises the disadvantage in similar mechanisms of the large type carrier disc restricting the space available for the paper feed and type and correction tapes. Improved visibility of completed type is achieved without the usual problem and moving the large carrier disc mass. The type letters are distributed on two carries, one behind the other, and optionally coupled together. The front carrier has an annular gap forming a viewing window and a space for the rear carrier type characters to pass through. The forward carrier is placed in a defined position when rear type characters are activated.

Title: Non-invasive destruction of kidney stones - uses device with annular reflector and insulating support in focal line, having HV terminals and electrode segments
Inventor: HAEUSLER EBERHARD PROF DR RER
IPC: G10K15/06
Filed: 1979-05-26
Abstract: In order to destroy kidney stones by a non-invasive method hydraulic shock waves are produced by high voltage discharge across underwater spark gaps. A chamber (1) filled with water has one side in the form of an elliptical reflector (R) with annular or spiral surface. The opposite side is an elastic membrane (4) faced with a water bag which moulds itself to the shape of the body or kidney. In the focal line (F1) of the reflector is a curved insulator (6) with a number of electrodes (7) mounted on it. The two end electrodes are connected to a high voltage source (8) which produces a series of simultaneous sparks resulting in hydraulic shock waves focused on to the kidney stone.
