Title: Four high mill for rolling soft metals - where linear relation is obtd. between rolling force and spring in roll frame
Inventor: BALD WILFRIED
IPC: B21B13/14
Filed: 1975-04-07
Abstract: Four-night rolling mill with stands contg. windows for work rolls mounted in chocks and hydraulically-operated back-up rolls for varying the roll-cap; and where work-cylinders mounted in the chocks and/or other window inserts press the work rolls aprt also after the rolled materials has left the mill.

Title: Apparatus forrr domestic preparation and or preservation of food - modified heating system utilises hot air distribution
Inventor: ANSCHUETZ THEO
IPC: A47J39/00
Filed: 1975-05-14
Abstract: The main patent concerns a deep sink-like trough set in a kitchen fitment, it has a cover, a fume extractor and a water supply, and can be heated.

Title: Foodstuff sterilising apparatus using two RF fields - uses low and high freqs. and food immersed in low loss dielectric liquid
Inventor: BACH JEAN DR
IPC: H05B6/60
Filed: 1975-06-12
Abstract: Sterilising apparatus, for foodstuffs such as milk, avoids known problems that occur when using electromagnetic fields to heat foodstuffs.

Title: Prodn. of polylaurinlactam in a homophase system - reaction time is greatly reduced in this way
Inventor: ENENSTEIN GENNADIJ ABOVITSCH
IPC: C08G69/16
Filed: 1976-01-13
Abstract: Polylaurinlactam is prepd. by hydrolytically polymerising laurin lactam in the presence of H2O, H3PO4 and a discarboxylic acid at 280-310 degrees C and 70-120 atmos. Water is removed by throttling the mixt. down to a press. of 0.1-0.005 atmos. under isothermal conditions at a flow rate of 20-90m/sec. The prepolymerisate is then polymerised at 280-300 degrees C in a 0.5-2mm. thick layer. Polylaurinlactam is widely used as insulation material for cables in the automobile and machine-building industries, for seals and gaskets and as containers for agricultural chemicals and oils. It is also used in the mfr. of filter fabrics, tooth brushes, special types of clothes, etc. Polymerisation time is greatly reduced compared with previous processes, because a homophase reaction system is used. In an example, polylaurinlactam was prepd. from a laurin lactam melt contg. 10 wt.% H2O, 0.2 wt.% H3PO4 and 0.2 wt.% adipic acid. The process is >=4-6 times faster than previous continuous processes.

Title: Household coffee maker with quick brewing action - has surface water level heated up to steam pressure before remaining water
Inventor: BOEHM HANS-GEORG DR
IPC: A47J31/54
Filed: 1976-05-20
Abstract: The household coffee maker with an air-tight fresh water supply container has a heating system. At least one part of instantly heated water or steam is produced at, or passed to, the surface of the water in the supply vessel so that this part of the vessel is heated quicker than the larger remaining volume. This means that the steam pressure required to start the flow of brewing water builds up faster on the surface allowing percolation or the like to begin much earlier than with conventional coffee makers.

Title: Appts. controlling vibrational chatter in machine tool - first transducer generates electrical signal representative of applied cutting forces
Inventor: NACHTIGAL CHESTER LEE
IPC: B23Q11/00
Filed: 1976-06-11
Abstract: A first transducer is spatially disposed from the tool-workpiece interface and generates an electrical signal representative of the applied cutting forces on the workpiece. This force signal is applied to a workpiece movement synthesis circuit for continuous calculation of the workpiece displacement in response to cutting forces and in accordance with continuously updated static and dynamic characteristics of the machine structure and workpiece. Simultaneously, another transducer on the machine structure continuously provides a tool acceleration signal for use in deriving an electrical signal representing the actual displacement of the tool. The synthesis circuit output signal representing the calculated workpiece displacement is electronically compared with the signal representing the actual tool displacement.

The paints adhere well to smooth, non-absorbent surfaces, under damp conditions, e.g. in kitchens or bathrooms. They are very resistant to saponification. (D) Allyl acetylacetate (II) is claimed. In an example, a paint prepd. from a copolymer of methacrylic acid, acrylic acid, butyl acrylate, styrene and (II) had an abrasion resistance in a wet brush test of >5000, a similar paint, in which the copolymer did nto contain (II), gave a value of 110.

Title: Automatic pot plant watering system - has drip valve for each pot operated by switch powered by mains transformer
Inventor: MALLACH MARTIN
IPC: A01G27/00
Filed: 1976-07-20
Abstract: Automatic pot plant watering unit comprises a water storage tank above the level of the flower pot with thin, flexible plastics pipes leading to drip valves (8). Electric wiring passes from a mains-operated transformer (7) to an interrupter switch (9) in the saucer of the flower pot. When the water level in the saucer falls sufficiently low for the light-weight portion (12) of the interrupter to settle on the heavier lower portion (11), a contact is closed and the drip valve is actuated. In this way pot plants are watered according to individual requirements.

Title: Hydraulically operated cylinder arrangement - auxiliary piston is fitted to open ended piston tube in initial feed path
Inventor: HELLER RUDOLF
IPC: F15B15/14
Filed: 1976-07-23
Abstract: The pneumatic cylinder arrangement is for moving a piston rod connected with a servo component. In the initial feed path of the main piston in one direction of motion, an increased load opposes the piston rod. An auxiliary piston, coaxial with the main piston, reinforces the movement of the main piston within this initial feed path. The auxiliary piston (2) is fitted to one end of a both sides open piston tube (5) in the length of the initial feed path. The other end of the auxiliary piston (2) is passed through a solid cylinder wall (4) so that it can move in a pressure-tight fashion. This cylinder wall divides the main piston (1) from the auxiliary piston (2).

Title: Warp knitter partial weft insertion - uses separate weft guides on guide bar to increase effects without reducing machine speed
Inventor: KOHL KARL
IPC: D04B27/26
Filed: 1977-02-18
Abstract: On a warp knitter which uses a number of partial wefts to build up the fabric, a weft guide is mounted to a reciprocating guide bar, so that the guide can be given an equal or different stroke length during the reciprocating movement. The design allows greater flexibility in the character of fabrics produced, and the weft insertion process does not affect the machine speed as only the individual weft guides are manipulated to give the special effects.

Title: Gate valve with rapid closure action - has pneumatic pressure biased piston actuator held back by releasable latch
Inventor: KAMMERER HANS
IPC: F16K31/124
Filed: 1977-02-28

Title: Automatic camera focusing system - measures light received from object illuminated at two distances from illumination source
Inventor: BIRGMEIR KLAUS DIPL PHYS
IPC: G01S17/02
Filed: 1977-04-29
Abstract: Automatic camera focusing system measures the illumination by a source of an object at different distances and analyses the resulting signals using the equation E = I/r2 where E is the illumination with the object at a distance r and I is the light intensity provided by the system. For a given distance between camera and object the latter is illuminated from two different distances. The two illumination values are measured and the signals are analysed using E = I/r2. The quotient of the signals is used to product a focus control signal corresponding to the range detected. This compensates for variations in light source strength and reflective qualities of the object.
