Title: Durable flame retardant treatment of fabrics - by grafting with unsatd. phosphorus or halogen cpds. using electron beam irradiation
Inventor: NABLO SAMUEL VICTOR
IPC: D06M14/34
Filed: 1980-01-07
Abstract: In a process for the durable flame-retardant treatment of nylon, polyester and cellulosic fabrics, the fabric is first treated with a soln. of a phosphorus- or halogen-rich fire retardant agent (I) and a copolymerisation grafting agent (II) to give a pick-up of nearly = 15-50 wt.%. The fabric is at least partially dried, then irradiated with an electron curtain beam perpendicular to the fabric. The applied energy level is 50-250 ke V, and  the level required to penetrate the average thickness of the fabric. The electrons in the beam are scattered between the fabric fibres to extend the effective range of electron penetration. The fabric is moved past the beam at 7-50 metres/min. and the dose is adjusted to a level of 2-5 megarads, to graft the (I) onto the fibres. The treated fabrics have excellent durable flame retardancy with good wash resistance. The prods. are useful e.g. in children's clothing and nightwear, mattress and bedspared fillers, etc.

Title: Hot air dryer for open width textile material - has several pairs of superimposed suction drums arranged in series
IPC: F26B13/16
Filed: 1980-02-22
Abstract: A hot-air dryer for open-width textiles or fibrous webs comprises at least two pairs of suction drums in a common housing, one drum of each pair being above the other, and the two pairs being on the same level, sepd. by a short distance which is bridged by a belt conveyor. The feed air to the dryer is delivered in the space between the pairs of drums as well as to either end of the machine, and penetrates uniformly to each of the drums through a mesh covering which concentrically surrounds all of them. This arrangement improves the drying efficiency with upwards of a single pair of drums by increasing the wrap angle of the material around all of the drums compared to the angle of wrap which is possible in a single multi-drum stack, and improving the distribution of ingoing air to all the drums to maintain a uniform temp. throughout.

Title: Rotary field excited synchronous motor and converter - is controlled by circuit with synthetic inverter thyristor firing pulse regulation
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H02P25/02
Filed: 1980-08-13
Abstract: The simplified gating control system for the inverter for a rotary field excited synchronous motor and converter as in the main patent, has the firing pulses for the thyristors of the machine side of the converter released by the rotary voltage system, following the commutating impedance, in a synthetic arrangement. This uses the armature rotation voltage with compensation for interruptions. Each armature current is received by a current converter and a simulating network, a part voltage being proportional to the output current to give a coefficient, and a second voltage corresponding to the speed change giving a second coefficient. These two are added to give a voltage proportional to the star connection voltage from the armature. These are used to compensate for the compensation for commutation interruptions. The synthetic output voltages have needle shaped peaks. A multi-phase passive or active low pass filter is used for the synthetic system.

Patent DE-3045065-A1 (DE)
Inventor: BERNHARDT STEFAN DIPL ING
IPC: B26D5/12
Filed: 1980-11-29
Abstract: Method and device of this type are used predominantly for comminuting frozen material, in particular for comminuting frozen blocks of fish in fish-processing plants. The objective of the invention is to continue the process of comminuting frozen material automatically even when relatively high cutting forces occur and, in this process, to avoid overloadings of the device over a relatively long period. The objective of the invention is to provide a method and a device with which these relatively high forces can be overcome by the blade drive. According to the invention, the objective was achieved in that the system is set to a specific working pressure and, in the system, there is an additional pressure range which is additional to the working pressure. This additional pressure range has the purpose that, when the working pressure is exceeded during the cutting process, multiple repetition of the cut with additional dynamic forces until the complete cutting through of the block of frozen material takes place.
