Title: Electronically operating automatic focussing system - uses multielement photosensitive sensor which scans optical field and results of successive scans are compared
Inventor: BAUTEL MARTIN DR
IPC: G02B7/36
Filed: 1976-03-19
Abstract: An automatic focussing device for cameras or projectors based on the use of electronics and light-sensitive elements. A sensor containing a number of light sensitive elements generates signals according to the intensity of light received, and it can be controlled in its distance from a point in the optical system by a control sginal. A circuit derives a mean signal value from all the individual sensor elements, whilst a second circuit determines the difference between each individual signal and this mean value. A third circuit forms the sum of all the positive or negative difference generated in the second circuit over a scanning cycle covering all the individual elements. The output signal from the third circuit over one cycle is compared in a fourth circuit for successive scanning cycles and according as the result is greater or smaller, generates a control signal to shift the focus in one sense or the other.

Title: Underfloor air conditioning grid - has sloping discharge and collection slots for air to be discharged in different directions
IPC: F24F13/16
Filed: 1976-04-03
Abstract: The underfloor air conditioning system has plates (10) incorporated in the floor each with an opening formed by a surround of e.g. aluminium in which is mounted a set of air delivery grids (15) and nearby, a set of collector grids. The partitions (17, 23) of these grids slope in various directions and give a laminar air flow with reduced turbulance. Each grid can be square or polygonal in plain view, and the spaces between the partitions are rectangular, and parallel. The delivery grids can be in a row e.g. floor, to deliver air in four different directions. For extraction, the slots need only be parallel.

Title: Continuous web dryer using recuperated heat - has hot and fresh air mixed near perforated plates forming air cushion
Inventor: VITS HILMAR
IPC: F26B23/02
Filed: 1976-04-14
Abstract: The continuous web from an offset rotary printing machine is passed through a drying chamber from which the hot gases are extracted and conveyed upwards through a heat exchanger located in the flue gas chimney above the burners. Branch lines from the burner chamber convey hot air to a mixer system at the entry and discharge openings for the paper web, so as to preheat the incoming fresh air. The hot air passes through jet openings which angle the flow onto the upper and lower surfaces of the web. Air passes through perforations in the convex faces of guide sheets above and below the web, so that it is suspended on and air cushion.

Title: Raised printing type esp. for typewriter - enables both normal impressions and mosaic printing to be effected on one machine
Inventor: RITTBERG EILT-HEYO DIPL ING
IPC: B41J3/50
Filed: 1976-08-11
Abstract: Type carriers for typewriter or similar office machine are so designed that either complete alphanumeric symbols can be produced for normal correspondence or mosaic printing for long-distance copying without the need to change carriers. The type surfaces (9, 11) have raised points (13) at key positions which serve to form the mosaic image. During normal typing against the elastic backing for the paper the complete symbol is formed. By interposing an inelastic strip (27) along the typing line behind the paper the normal complete symbol is not formed and only the dot-mosaic image is formed. The strip is mounted between arms which are swivably mounted on the axle of the typewriter platen so that it can be moved into a neutral position when not required.

Title: Ortho-phenyl phenols prepn. by condensing cylohexanone - and dehydrogenating cyclohexenyl cyclohexanone with metal catalyst in presence of sulphur
Inventor: KING IAN ROBERT
IPC: C07C37/07
Filed: 1976-10-22
Abstract: O-phenyl phenols are prepd. by (a) condensing a cyclohexanone using a condensation catalyst other than a naphthenate to form a mixt. contg. o-cyclohexenyl cyclohexanone (I), (b) recoverin (I) and (c) dehydrogenating (I) by contacting it with a Ru, Rh, Os, Ir, Pt or Pd met al dehydrogenation catalyst and sulphur, or an organo-sulphide or thiol, the sulphur/dehydrogenation catalyst metal wt. ratio being 1/60 to 1/12. The presence of the sulphur improves the selectivity of the dehydrogenation catalyst in favour of o-phenyl phenol. In an example, 5.52 ppm total sulphur increased the yield of o-phenyl phenol from 58.7% to >98%.

Patent DE-2708971-A1 (DE)
Inventor: BAUMGARTNER EUGEN
IPC: G05D9/12
Filed: 1977-03-02
Abstract: A tank (10) possesses a feed pipe (14, 15, 16) which penetrates into the latter and the end of which is vertically adjustable. A flow-off pipe (6, 8, 13) likewise penetrates into the tank, its end being held fixedly. A float arrangement (17, 18, 19) serves for controlling a feed pump (23). The flow-off pipe, together with the fresh-water supply pipe (6), forms a jet pump for a washing drum (1). By means of the above-defined apparatus, liquid treatment agents can be fed in an exactly and uniformly metered manner to the treatment liquid required for the working process, before the latter is allowed to flow into the treatment appliance, especially an industrial drum-type washing or dyeing machine. A treatment appliance provided with this metering apparatus needs no special inlet for liquid treatment agents. <IMAGE>

Title: Powerful passive electrooptical display cell - has rustless steel frame with sintered glass frit separating glass plates
Inventor: SALLIN MICHEL
IPC: G02F1/167
Filed: 1977-05-13
Abstract: A passive electro-optical display cell consists of two glass plates with conductive symbols between which an active component (electrophoretic) is sealed. A cross strut frame which keeps the plates at the proper spacing is made of hot oxidising steel which is bonded to both plates by a glass frit layer. This makes it possible to design more powerful display cells with greater distances of the glass plates. Glass frit without the new strut frame would expand too much during the heating which is required for their sintering operation. Useful e.g. in watch making.
