Title: Oscillating plate mach. for cont. mastication of moulding materials - suitable for bulk or powdered rubbers etc.
Inventor: BERTRAM JUERGEN
IPC: B29B7/36
Filed: 1976-03-25
Abstract: A mastication machine for working and homogenising moulding materials, includes rubbers, where the working chamber comprises an open ended passage between a stationary base plate having an undulating surface and a top plate with a complementary undulating surface moving with cyclic oscillation between the crests of the base plate profile, producing the effect of a linear peristaltic pump with multiple lobes. Suitable in principle for masticating any dry blend compsn., including powdered or crum materials. Readily accepts a wider range of particle sizes than screwfed machines. Progressive pumping and discharge of the material occurs continuously, in contract to batch mixing in rotary kneading machines.

Title: Single stage gas press. reducer - has opposing piston receiving varying press. force in connecting bore to pressurized gas cylinder to provide constant working press.
Inventor: JOHN DIETER
IPC: G05D16/10
Filed: 1976-04-14
Abstract: The pressure reducer brings highly pressurised gases to a working press. as used e.g. in welding and anaesthetics. The pressurised gases are usually kept at 150-300 bar in steel cylinders and the working press. is between 0.5-10 bar. The present reducer has an opposing piston to receive the forces arising in the connecting bore. The reducer works in one stage provides a working press. independent of the original high press. The main body is screwed into the valve. A spring lifts the piston to its upper end position. The gas rushes through the bore, meets the other piston and passes the first piston in the intermediate space.
Patent DE-2621179-A1 (DE)
Title: Detection of direction of rotation of e.g. fan - using 3 scanners to detect raster signal and apply it to flip-flops which control 3 stores
Inventor: BAJORAT KLAUS
IPC: G01P13/04
Filed: 1976-05-11
Abstract: The detection method is to ascertain the direction of rotation of a revolving component, esp. a fan of an electric machine. First, a raster is scanned by polyphase scanning by optoelectronic, electrostatic or magneto-electric means. Signals so obtained are processed by an evaluation logic system which delivers a signal showing the director of rotation. Three scanners, spaced at phase angles of 120 degrees detect the same flank of a raster signal and apply it to a monostable flip-flop which delivers it as a pulse to electronic stores. Pulse of a first of the flip-flops sets two stores, and each store is reset by the pulse of one of the other two flip-flops.

Title: Controlling insects of genera IPs and Porthetria - by applying an enantiomer of their natural attractant to destroy chemical communication
Inventor: VITE JEAN P PROF
IPC: A01N61/00
Filed: 1976-10-18
Abstract: Compsns. for controlling insects of the genera Ips and Porthetria contain an enantiomer (I) of a cpd. which is an attractant for the species in question. (I) is distributed into the atmos. over the appropriate area, pref. to a concn. >=10 times that of the natural attractant, so as to interrupt or destroy chemical communication between the insects. For Ips species (R)-cis-verbenol (Ia) is used and for Porthetria species (758R)-(-)-disparlur (Ib). The insects are made to find mates and to congregate at feeding points. Standard insecticides are unnecessary so pollution is avoided.

Title: Multistage catalytic oxidn. of sulphur di:oxide to tri:oxide - with continuous cooling by common liquid heat transfer medium
Inventor: STAUFFER ADOLF DIPL CHEM
IPC: C01B17/80
Filed: 1976-10-23
Abstract: Multistage catalytic oxidn. of SO2 to SO3 is carried out with continuous cooling in each stage along the contact path, using a common liquid heat exchange medium. The sum of the heat transferred in the individual stages is removed in (partial) amts. of heat bearing no relation to the amt. produced in the individual stages and is transferred to the process gas, the waste heat boiler or the steam superheater and any necessary heat requirement of the entire system is supplied from external sources. All stages are always at the correct operating temp., since the heat exchange medium is circulated so strongly that only a slight temp. difference (1-2 degrees, max. 5 degrees) occurs. The process is not confined to the oxidn. of SO2 to SO3 at the usual SO2 concns. but can use SO2 and/or O2 contents as high as 100%. The appts. consists of an upright cylinder, through which a number of tubes pass, (some of) which are (partly) filled with a suitable catalyst, whilst groups of tubes can be charged separately. The tubes are surrounded by the circulating heat transfer medium.

Title: Hollow fibre assembly for osmotic separation - having fibres in transverse planes with flow along axis of module perpendicular to fibres
Inventor: ELGETI KLAUS PROF DR
IPC: B01D63/02
Filed: 1976-11-03
Abstract: A hollow fibre module for osmotic sepn. processes comprises an arrangement of hollow fibres, generally not parallel to one another, in planes perpendicular to the direction of flow of the fluid and to the axis of the module itself. The openings (outlets) of the hollow fibres are arranged around the periphery, typically the cylindrical wall of the module. Pref. the module is composed of a series of discs, stacked one after the other and replaceable as desired. The liq. to be purified passes transversely to the fibres and thus a high degree of turbulent is produced in the flow, which tends to prevent accumulation of concentrates on the outside of the fibres. In addition, the flow rate remains relatively uniform, not decreasing progressively as it does when the flow is radially outwards through a cylindrical module. The fibres are not crumpled (as with a previous arrangement) and therefore are not subjected to stresses which detract from their efficiency.

Two separate dies are used for each of two wires for both the first and last drawing passes. Design saves a substantial amt. of space, which is esp. suitable for converting a single wire drawing machine into a multiple wire drawing machine, esp. using similar components.

It consists of a series of aluminium plates combined into a bundle with ribs in the plates to serve as spacers. These can be formed by punching or pressing so that the ribs on one plate contact those on an adjoining plate. Parallel to the ribs, the edges of the plates are sloped and terminate in a flat rim at the same level as the ribs. These are then used as sealing surfaces and an elastic seal is laid on them. The bundle can then be built up. For indirect contact for heat transfer between flowing media. The method extends the slope of possible sizes from small compact units to those of 3m cube proportions.

Title: Coin checking stage for sorting machine inputs - has photoelectric sensors detecting coin passage coupled to counter to control number of coins
IPC: G07F1/04
Filed: 1977-11-30
Abstract: Photo-electric sensors operating in conjunction with a counter provides a means of checking coin denominations in sorting machine and providing an automatic release mechanism. Coins entered through a slot pass over a photo sensor. The coins drop onto a balance that reacts to the required weight. Correct coins are passed to an output chute that has a second photosensor. Coins that are too small fall into a reject chute. A counter is preset to control the number of coins in the chute and a gate coupled with a timing stage ensure that the release is operated at the correct point.

Title: Focussing optics for camera - has focus detector receiving focussing beam path through imaging lens and delivering corrective electrical signal
Inventor: BLETZ WALTER DIPL ING
IPC: G02B7/04
Filed: 1978-03-02
Abstract: The objective lens of an optical imaging device is focussed by using another lens (2) which is movable along the focussing beam path. The respective position of this lens (2) is characteristic of the deviation of the objective lens (1) from the position of ideal focus. An electrical signal proportional to this deviation is obtained and delivered to a setting device for the objective lens (1) to an indicator for subsequent manual adjustment.
