Patent DE-2920501-A1 (DE)
Inventor: GANSTER OTTO DR
IPC: C08G18/32
Filed: 1979-05-21
Abstract: This invention relates to a process for the production of non-cellular polyurethane ureas elastomers using a chain-extender mixture produced from asymmetrically alkyl-substituted anilines by condensation with formaldehyde. The chain-extending agents used in the instant invention show medium reactivity to compounds containing isocyanate groups. These chain-extending agents may be processed both in high-pressure and in low-pressure metering and mixing units because they are either liquid at room temperature or can be melted at relatively low temperatures (below 55 DEG  C.). The homogeneous, i.e. non-cellular, polyurethane urea elastomers obtained in the instant invention are distinguished by having excellent mechanical properties.

Title: Combination lock with comparator - receiving signal patterns stored in memory and entered via external keyboard
Inventor: MEYERS PIERRE DIPL ING
IPC: G07C9/00
Filed: 1979-05-31
Abstract: The combination lock has a keyboard for entering signal patterns. A memory stores reference patterns and, unlike the keyboard, is not accessible from outside the device. A comparator compares both patterns and unlocks the lock if they are identical. The user can enter a new reference pattern into the memory via the keyboard when he has unlocked the lock and when a switch inside the device has been switched to 'insert new pattern'. A delay switch delays the unlocking of the lock after the two patterns have been found identical. A decoupling circuit decouples the externally-accessible keyboard from the externally-inaccessible circuitry which includes memory, comparator, switch, unlocking devices etc.

Title: Matrix printer with magnetic fluid for fixing printing needles - uses individual energising coils to increase response speeds by eliminating magnetic gap
Inventor: GRIMM ARNOLD
IPC: B41J2/25
Filed: 1980-02-20
Abstract: The magnetic fluid in this type of matrix printer fixes selected needles in the forward position due to its high viscosity when energised for printing, resulting in a very compact printing head. The response speed is increased by attaching each needle to a freely moving coil, thus eliminating the magnetic gap. Each of the 35 printing needles is attached to the coil former (3) on which a coil (7) with connections (8,10) is wound. This coil moves freely within a tube (5), the gap between coil and tube being filled with a magnetic fluid (9). A similar principle is used for fixing the printing head in the forward position during the printing mode.
Patent DE-3019414-A1 (DE)
Title: Spirally wound thermoplastics sheet esp. for capacitors - has edge cut by hot bar then thermo-sealed to coil by radiation
Inventor: NITZKE KARL-HEINZ
IPC: B65H19/26
Filed: 1980-05-21
Abstract: The thermoplastics sheet (1) is cut by applying heat at a line (7) across the sheet at some distance from the wound core (3), and then the remaining portion of sheet (12) is seal- welded to the spirally wound object by contactless application of heat by radiation (across gap 9). As the thermoplastics sheet (1) enters the roll gap (2) between the spirally wound sheet (3) and counter-roll (4), it is finally cut at the desired position by a heated cutting bar (5); this bar can adopt three different positions; in position (I) it is remote from the coil and may be heated by radiation (6); in the cutting position (II) it makes the cut across the sheet, while in a further position (III) close to but out of contact with the roll it radiates heat from its flat face (8) across the gap (9) thus sealing the end of the cut sheet (11) to the spirally wound object. Excessive heat penetration into the assembly is avoided.
Patent DE-3022179-A1 (DE)
Title: Coke oven battery with dry coke quenching tower - served by balanced rope lift for hot coke container car
IPC: C10B39/02
Filed: 1980-06-13
Abstract: A coke oven battery is equipped with smoke tight containers to hold the entire contents of one coke oven chamber when the coke has been pushed out of it, and with a dry coke quenching tower into which the hot coke is dumped. The container is transferred from its track alongside a coke oven battery to the top of the dry quenching tower, situated at the end of the battery, and raised by a rope-operated lift. A counterweight which balances a part of the load weighs at least as much as an empty container. An empty container can, for example, be used as a balance weight and be lowered at the same time as a full container is hoisted up. This reduces the power costs for the rope lift. Instead of a hoist motor of 185kW, required to lift a full container of 50 Mp weight, a motor of 35 kW is adequate if the empty weight of 38 Mp is balanced.

The chamber (48) under the piston is connected by a line (60) with an upstream point of the conduit so that the liquid pressure operates the piston. The system operates so that the upstream conduit (10) is first blocked, then the closure member is pushed downwards so that the lower section (12) is open to atmosphere.
Patent DE-3024705-A1 (DE)
Inventor: SCHMIDT WALTER RICHARD ING
IPC: D04B9/12
Filed: 1980-06-30
Abstract: Patterned pile (terry or plush) fabrics are made on circular knitting machines with cylinder and sinker ring or latch needles and pile elements (pile sinkers, pile hooks, latch needles). The pile elements are not selected, but perform their pile forming motions every knitting cycle. The latch needles of the cylinder are, however, selected both for knitting desired structures in the ground or base fabric and for forming the pile loops in the desired pile regions. The needles selected to form pile loops engage the pile thread fed at a higher level than the ground thread, which is fed at a level such that it is not affected by the pile elements, e.g. below the webs of pile sinkers. The ground thread is held in non-pile forming needles with their hooks at the level of the pile elements while the pile thread is fed to further extended needles which are then retracted to the same level as the needles holding the ground thread before all the needles are retracted to the knock-over position.

Title: Passenger car with mechanical gearbox - has servomotor for gearbox actuation, controllable by switching pulses derived from accelerator pedal
Inventor: FIALA ERNST PROF DR
IPC: B60W10/10
Filed: 1980-11-04
Abstract: The mechanical gear box is connectable to the car drive engine via a clutch and is actuated by at least one servomotor. The latter is controllable by switching pulses generated in response to the car operational state. The servomotor (8), actuating the gear box (3), is controllable in response to the position of the accelerator pedal. Pref. the servomotor receives a pulse for engagement of a lower speed with the accelerator pedal fully depressed. With the pedal released below a min. value, or at its complete release, the servomotor receives a pulse for gear change to a higher gear speed. The servomotor may be controlled in dependence on the engine speed in such a manner that a speed change to lower gear speed takes place below an upper speed limit, while an upwards gear change to a higher speed takes place only above a lower speed limit.
