Title: Butterfly valve for pipe system - handles corrosive liquids and gases
Inventor: VOLKMANN WOLF-DIETER
IPC: F16K1/22
Filed: 1973-06-18
Abstract: The valve is of robust construction made in thermosetting plastic such as phenol or cresol-formaldehyde resin or furan resin to withstand temperatures up to 170 deg.C, and abrasion due to flow of medium. A central shaft of metal is threaded at each end and carries the heavy moulded plastic plate which is circular in form with edges chamfered to seal against the valve seating. The latter is formed inside the main body which butts against the two pipe ends. To strengthen the shaft in resisting torque when turning to open or close, the plate has an insert jacket with cam and adjusting spring. The shaft projects through a circular housing integral with body which carries a central bush and guide plates for manually operated handle.

Title: Optical sensitization of siliver halide emulsion - with betaine cyanines in aq (organic) colour coupler soln, for simplicity and stable sensitizer solns
Inventor: ECKERT JOHANNA
IPC: G03C1/12
Filed: 1973-08-20
Abstract: The sensitizer pref. is a thiacarbocyanine, esp. 9-methyl- or ethyl-substd. Joint addn. of the this and the colour coupler does not reduce the colour sensitivity and the pouring uniformity is better than usual. The solns. can be prepd. cheaply, allow the use of a wide range of final pH values and give a considerable redn. in the amt. of water-miscible solvent and/or dispersant needed. Wide ranging variations are possible in the process, since it is independent of the type, concn. and charge size of the Ag halide-gelatin emulsion and the usual additives.

Title: Folded filter paper produced by grooving rolls - fed with paper under slight thrust to compensate variations
Inventor: SAUER HEINZ
IPC: B31D5/00
Filed: 1973-10-18
Abstract: In making folded filter sheets, esp. folded paper strip, the strip is clamped between the grooving (creasing) rolls then a portion of strip on the feed side of these rolls is subjected to a pushing stress, which is released after the strip has been grooved. The variations in action caused by irregularities and unevenness of the paper are removed and uniform folding results. By varying the feed speed on the feed side of the grooving rolls, folds of different heights can be produced.

Title: Ratchet-type socket spanner - has locking member forced between housing and inner component ramp face
Inventor: BEER JOSEF ADAM JOHANNES DE
IPC: B25B13/46
Filed: 1973-12-11
Abstract: The ratchet effect tis provided by a housing at one end of the spanner, with a circular inner face, and contg. a component rotating in relation to it and coupled to the socket. The component has a locking face diverging from the housing inner face, and a round locking member fits between these two faces, being forced by a spring in the direction in which the two faces converge towards each other. Thus in one direction the housing rotates freely in relation to the component, while in the other the two are locked together. The component can have an axial boss for accommodating the socket or an aperture to accommodate the boss, which can be arranged to slide between two end positions, to allow use of the spanner both for tightening and unscrewing.

Title: Correcting attachment for gear grinding machine - uses controlled pressure of grinding wheel on tooth flank of workpiece
Inventor: LOOS HERBERT
IPC: B23F5/06
Filed: 1974-12-13
Abstract: The gear grinding machine has a roller drive which actuates the rotary component of the roller bands, supported on at least on roller segments. Between the workpiece carrying spindle and the roller segments support element is mounted a workpiece device, operating from tooth to tooth. The carriage for both the workpiece and the roller segment(s) reciprocates across the workpiece carrying spindle in the rhythm of the roller movement, without any longitudinal motion parallel to the workpiece spindle axis. A special device provides an additional transverse movement of the gear tooth relative to the grinding wheel (19). The pressure of the grinding wheel on the tooth flank of the workpiece (5) is appropriately controlled, with the roller bands tension remaining constant.

Title: Discharging liquid from spraying containers - flexible cartridge filled with compressed aiir and inserted in container
Inventor: ODE BERND
IPC: B65D83/14
Filed: 1975-01-11
Abstract: Device for discharging liquid from spraying containers consists of a flexible cartridge enclosing compressed air. The cartridge, which is inserted in the container exerts a pressure against the sprayed liquid and replaces the normally used expensive gases which in some cases could polute the surrounding space. The compressed air enclosed in the cartridge does not mix with the discharged liquid. Depending upon the shape of the bottle and the fluid to be sprayed there is nothing further to prevent the cartridge from being manufactured from a plastics tube of regular wall strength having an outer diameter about 1mm les than the inner diameter of the bottle.
Patent DE-2505391-A1 (DE)
Title: Milling machine precision tool control - has light or laser beam transmiTER ON TOOL RAM HAVING HYDROSTATIC BEARING
Inventor: DRECHSLER GUIDO
IPC: B23Q15/22
Filed: 1975-02-08
Abstract: The method for precision control of mobile milling heads, slides or rams with the aid of normal light or laser beams, reduces the drift caused by pressure forces to a value of 20 - 50. In a large milling machine with a portal (1), there is a cross carrier (2) which in turn carries the ram (3) for location of a milling tool. The cross carrier (2) moves upwards and downwards in relation to the portal (1) whilst the ram (3) can be displaced to the left and right. The ram (3) has a hydrostatic bearing (6), and a plumb (7) in which a laser beam transmitter (8) is located. The laser beam comes in contact with a convex mirror (9) located in a dust-proof receiver housing (10).
Patent DE-2517635-A1 (DE)
Title: Change-over valve for back-flushing water filters - with actuation by change in water flow rate
Inventor: SCHNEIDER ERNST
IPC: B01D35/14
Filed: 1975-04-22
Abstract: An automatic regulating and change-over valve is described in which a movable piston rod carrying three piston discs can cover or uncover ports in the valve housing and so change the direction of flow of the incoming water flowing into a filter system. Change in the resistance of the latter causes a control valve to open, admitting pressure into a chamber in the valve and thereby causing the pistons to be moved, the ports covered or uncovered, and so the route of the water flow to the filter changed, and contaminated water diverted to drain. Valve is used for water filters with back-flushing facilities, as employed for clarifying drinking water or swimming pool water. Being responsive to change in water flow (caused by an increased in back pressure of the filter as it becomes dirty) rather than to changes in pressure, the valve more truly reflects the condition of the filter. Its operation is independent of external power supplies and requires no timing devices and is essentially self-actuated.
Patent DE-2517907-A1 (DE)
Title: Electro pneumatic signal converter - with path displacement for control member coupled to servo drive
