Title: Multilayer facing cloth for offset printing - has axial capillaries contg. incompressible fluid to compensate irregularities
Inventor: BOSSE ROLF DR ING
IPC: B41N10/04
Filed: 1976-06-29
Abstract: A multi-layer printing cloth comprises a covering layer, pref. of rubber, a volumetrically compressible intermediate layer and a basic fabric. The volumetrically compressible intermediate layer contains capillary ducts parallel to the axis of the printing roll, these ducts being entirely or partially filled with an incompressible medium. The ducts may be subdivided into chambers by membranes. Pref. the intermediate layer has, on one or both sides, layers having low strain in the circumferential direction of the roll. In addition there may be a porous layer. The incompressible fluid in the ducts results in a limited amt. of compensation of irregularities along the axis of the roll, e.g. irregularities in the paper. This is achieved with a uniform pressure distribution, unlike the results obtd. when the ducts are filled with a compressible gas.

Title: High voltage circuit breaker hydraulic actuator - has auxiliary accumulator between pump and main accumulator to reduce pump capacity
Inventor: GRIEGER GERHARD ING GRAD
IPC: H01H33/34
Filed: 1976-06-30
Abstract: Reduced power requirements for the hydraulic actuator supply for the starting period in the control of high-voltage circuit breakers is achieved by installing an auxiliary accumulator between the pump and the main accumulator. The pump charges the auxiliary accumulator and compensation of leaks during the initial starting period allows for setting of the control valves. The unit operates the moving contact (1) of the circuit breaker whose insulator rod (2) is connected to the piston (3) of the cylinder (4). The piston is of the differential type with the small area (6) subject to pressure of the accumulator (8). The flow is controlled by a valve (9) with a step spool. The auxiliary accumulator (18) has a floating piston (19) loaded by a spring (20) with its pressurization is controlled by the setting of springs (25/30) of its control unit.

Title: Cyclohexyl methacrylate (co)polymers for optical use - e.g. lenses, have good refractive index and low water absorption
Inventor: WINGLER FRANK DR
IPC: G02B1/04
Filed: 1976-08-07
Abstract: (Co)polymers of cyclohexylmethacrylate (I) are used as light diffracting materials for making optical systems, esp. lenses for camaras, projectors and other optical equipment. Esp. good results are obtd. using copolymers of (I) with 1-80 wt. %, esp. 10-70 wt. % of a comonomer contg. aromatic gps., such as styrene or phenylmethcrylate. Pref. copolymers have an intrinsic viscosity (THF at 25 degrees C) of 0.3 - 2.5 dl/g, esp. 0.4-1.0 dl/g, a refractive index nD = 1.50 - 1.58 and an Abbe' index vD = 61-32. The (co)polymers are clear, colourless transparent materials with the optical properties required for lens mfr., esp. refractive index, and have a low shrinkage, low coefft. of expansion, low water absorption and good thermal stability up to 80 degrees C. They can be processed as thermoplastics, which allows rationalised production techniques to be used for making the lenses etc. Due to the low water absorption, the resulting lenses retain their geometry in use better than lenses made of polymethymethacrylate.
Patent DE-2635819-A1 (DE)
Inventor: STRELLI ALBERT
IPC: B60C27/16
Filed: 1976-08-09
Abstract: The anti-skid device comprises a chain which is composed of links (1', 1'') pivotably connected to one another, and which can be secured to the tread of the vehicle tyre. Anti-skid devices of this type are used to prevent the vehicle tyre from sliding in difficult ground conditions, for example in the case of a layer of snow on travel routes, in the case of slush etc. and to increase driving safety. Problems arise particularly when fitting anti-skid devices of this type. In order to be able to fit the anti-skid device on a vehicle tyre easily and without the use of force, the chain is designed such that it can be elastically extended in the direction of its longitudinal extent thanks to elastic elements, such as, for example, rubber buffers (3). The elastic elements are here inserted between at least two of the chain links connected to one another. <IMAGE>

Title: Motor-driven air compressor control - has sensor to switch compressor the max. when demand drops below given limit
Inventor: ZOLLDANN WOLF ING GRAD
IPC: F04B49/22
Filed: 1977-04-19
Abstract: The control system is for a compressed air installation comprising an electrically driven compressor and a pressure vessel to control the compressor output as a direct function of the demand. When the demand falls below a given level, the pressure in the vessel increases to a given maximum at which the compressor is switched-off or is switched to idling until the pressure drops to a given minimum. When the demand falls below its given value, the compressor is switched to maximum output to rapidly build up the pressure in the vessel to the level where it switches the compressor off or to idling. The demand may be determined from the pressure between the compressor and an upstream throttle. The lower demand level may be at 70 to 30% of maximum air flow.

Title: Desulphurisation of flue gases, esp. from coal-fired power stations - by scrubbing with dilute sulphuric acid contg. ferrous sulphate oxidn. catalyst
Inventor: SEYFRIED WOLFGANG
IPC: B01D53/50
Filed: 1977-08-12
Abstract: Desulphurisation involves scrubbing and catalytic oxidn. of the SO2-enriched wash liquor to H2SO4. The Fe(II) sulphate catalyst is added to the liquor in the scrubber and is removed electrolytically as Fe from a side stream of the acid, the Fe being returned to the wash liquor via dissoln. equipment. The process allows recycling of the catalyst and removal of all harmful materials present in the flue gas. Environmental pollution is avoided, since no waste liquor with a high chloride content is produced. The process can be combined with other processes to give marketable or disposable end-prods., e.g. 76% H2SO4 useful in pickling, fertiliser mfr. etc. Subsequent processes include conversion of the Cl2 formed in electrolysis to hypochlorite and use of this and the water used for washing the solids filtered from the side stream for prepn. and decarbonation of the cooling tower water; and concn. of the excess acid from electrolysis, with recovery of HCl acid contg. small amts. of HF and conversion of the NO formed to N2.

Title: Automatically closing fire screening rolling door - has auxiliary low current brake delaying complete closure to permit passage
Inventor: EFFERTZ-LEX HERBERT
IPC: E06B9/70
Filed: 1977-10-15
Abstract: The large roller door has a sheet which rolls up on a spindle, under power drive. It automatically slides into the closed position in the event of a fire alarm, under its own weight, by venting action on an electromagnetic brake.
