Patent DE-2531851-A1 (DE)
Title: Plastic suspension rail attachment to pockets or folders - with stacked flat material moved by knife element on to suspension rail for folding over
Inventor: BRUEGMANN DIRK ALEXANDER
IPC: B42C7/00
Filed: 1975-07-16
Abstract: The suspension rail has a 'U' shaped profile. One leg forms, with a stay, a sliding wedge opening outwards. The leg (12) has the stay (16) part of the suspension rail (10) parallel to the legs (12, 14) so that the end section extends beyond the stay (16) of the suspension rail (10). The stacked material (24) is moved by the knife element (55) on to the supported suspension rail (10) in such a way that the end section of the material is bent over by about 90 degrees whilst making a folding strip. The folding strip is then turned over by a further angle during the insertion of the knife element (55) with its folding edge forward in the wedge opening (22) between the legs (12, 14) of the suspension rail. The folding strip is held in the angle space between stay (16) and leg (12) during withdrawal of the knife element.

Title: Gas mass flow measurement in pipe - has acoustic waves propagated upstream and downstream for measurement of velocity
Inventor: REIBER HANS ING GRAD
IPC: G01F1/66
Filed: 1975-09-01
Abstract: The device has a first means (1) measuring the phase difference between a frequency propagating in and against the flow direction. There are second independent means (2) which measure the pressure in the pipe. and there are third means (3) which multiply the phase difference as the measure for V/T (flow velocity/absolute temperature) by pressure and by an instrument constant obtained by the device calibration. The apparatus uses only two transducers, (St1, St2) which are connected directly to the phase comparator (11). The device has linear characteristics.

Title: Dynamic MOS memory regeneration circuit - with regeneration effected in first part of each working cycle
Inventor: DANGEL JUERGEN DIPL PHYS
IPC: G11C11/406
Filed: 1975-09-30
Abstract: The method is for the regeneration of the content of a MOS memory, in which working cycle of the memory is is divided into a first period in which only regenerative processes occur and a second period in which only reading or writing processes occur. A MOS memory to operate on this principle consists of a set of memory cells with a decoder connected to the word lines and with reading and writing amplifiers connected to the bit lines and a clock unit under the control of a central unit. After the clock unit (37) a divider (35) is connected. A cyclic counter (34) determines the cells to be regenerated, an address register (33) stores the working addresses, and between the address register and the decoder (31) a multiplexer is inserted (32). The cyclic counter may be a shirt register. The system is particularly suitable for small memories with relatively simple dynamic cells having a low retention time.

Title: Synchronous machine for peak load supply - is coupled to flywheel and is joined to power system by static converter
Inventor: HENSEL WILFRIED DR ING
IPC: H02J3/30
Filed: 1975-10-18
Abstract: A synchronous machine to cover short duration peak loads is coupled to a fly wheel which feeds power into the distribution system through a static frequency converter. The unit is driven up to a high speed during off peak periods thus helping towards a constant load on the supply system main generators. For example, a tranformer couples the unit to the power system, and a rectifier and inverter unit match machine and system frequency when output is required. The rotating masses are driven up to a high speed by a d.c. motor supplied from the rectifier part of the frequency converter. Alternatively the synchronous machine may also be used as the motor by suitable aterations to the static converter controls. Units of 1MWh capacity are projected.

Title: Grafting thermoplastics or elastomers with silanes - in presence of crosslinking agents and lubricants esp. aromatic oils
Inventor: KEUPER DIETER
IPC: C08F255/02
Filed: 1975-12-06
Abstract: Parent patent discloses a process for preparing moisture-crosslinkable thermoplastics, e.g. olefine (co)polymers and elastomers, by grafting a silane cpd. The individual flowable thermoplastic particles, e.g. as powders or granulates, are subjected to energy-rich movement. The silane or silane cpd. together with auxiliaries for grafting and crosslinking, are added in liquid form, during or before movement. Liquids diffuse, at least partly into surface of the thermoplastic particles below crystallite melting range. The uniformly distributed silane or silane cpds are then grafted on thermoplastic. According to present modification, lubricants are added to mixt. before or during mixing. Prods. are used for sheathing elongated material, e.g. electric cables, conduits and pipes. Lubricant addn. prevents abrasion of g granulate particles. Extrusion of thermoplastic can take place without impairing properties of injected material. In an example, a coating compsn. contains 100 wt. % polyethylene, grafting and crosslinking additives, and, as lubricant, 0.5-2.5 wt. % alkyl-substd. naphthalene.
