Title: Pneumatic lift for fire extinguisher during mfr - has fan-inflated rubber body between parallel plates coupled by scissors linkages
IPC: B66F7/08
Filed: 1978-11-25
Abstract: The pneumatic machine lifts and lowers fire extinguishers of different sizes to be filled with powder. It comprises a pair of lifting plates (2, 4) one above the other and parallel coupled together by scissors linkages (3) on opposite sides. Between them is a hollow airtight rubber body (5) enclosed by reinforcing textile material and inflated by a fan. This varies the distance between the plates dependent on the air quantity delivered, while keeping them parallel.

Title: Oxalic acid prepn. - by reductive oxalation of carbon di:oxide in electrolysis cell with an electronegative metal anode
Inventor: FISCHER J DR
IPC: C25B3/25
Filed: 1978-12-16
Abstract: In an electrochemical process for the prodn. of oxalic acid, CO2 is led up to an electrically (semi)conductive cathode in an electrolysis cell, and is reduced by oxalation. The cell contains a single, non-partitioned, aprotic electrolyte and the anode is composed of an electronegative metal or alloy giving metal ions which form insoluble oxalates with oxalate ions. The resulting insoluble oxalate is sepd and treated with a strong acid to form oxalic acid. Pref the anode is of Zn and H2SO4 is used to liberate the oxalic acid. The metal salt or sulphate formed as by-prod. is pref. subjected to electrolytic treatment to recover the metal. The operations may be carried out continuously in a recirculation process which need virtually no input of chemicals. The process overcomes the drawbacks of prior art electrolytic oxalic acid prodn processes, and does not require the use of compartmentalised electrolysis cells. The process can be operated continuously on a prodn scale.

Title: Photosensitive detector for paper document format - has light sensor and comparator with network applying variable reference voltage
Inventor: FAEDI LEONARDO DIPL ING
IPC: C12Q1/42
Filed: 1979-01-19
Abstract: The paper document format detector has a light sensor (2) connected to a voltage source (1), whose internal resistance changes with the received light.

Title: Wall mounted flap closing mechanism - has support edge and elastic strip forming hinge stretched on opening
Inventor: KREYENBRINK ALFONS
IPC: E05F1/12
Filed: 1979-09-28
Abstract: An energy-storing unit permits a flap or trap-door in a wall to close itself, butting against a stop. This unit is an elastic strip (6), combinging with a mounting edge (4) parallel to it, to form a hinge joint, so that the strip is stretched when the flap (3) is opened.

Title: Connection between plastics component and baseplate - uses cylindrical projections dipped into solvent before insertion into holes, causing deformation and locking
Inventor: BURGER GEORG
IPC: B29C65/60
Filed: 1979-09-28
Abstract: The method of forming a connection between a plastics member or component (i) and a baseplate, uses one or more hollow cylindrical projections (2) integral with the component, which are fitted through holes (3) in the base plate. These projections are chemically treated to form a permanent connection. The lower part of each cylinder is immersed to a depth (T) corresponding to the amount by which it will project below the baseplate after assembly, in a solvent. After assembly , the projecting part is deformed to give a permanent joint. The amount of solvent application depends on the shape and material of the treated part. Useful for attaching cladding to technical derivs or cupboards etc.

Title: Dispenser for pastes and viscous liquids - having piston on screw actuated by pusher with ratchet on top to deliver fixed amount of paste
Inventor: LORSCHEIDT WILLY
IPC: B65D83/00
Filed: 1979-10-12
Abstract: Dispenser is for pastes and viscous liqs. and consists of a cylindrical container with a piston inside it. It is used for cosmetics, pharmaceuticals etc. The container has a threaded shaft down the centre on which the piston moves. At the top is a spring loaded pusher also with a screw thread. When the pusher is depressed with a finger, the shaft is rotated and the piston moves up. As the piston moves by a fixed amount., a fixed quantity of material is discharged from the outlet at the top. There is a ratchet mechanism at the base of the pusher at the top end of the shaft which only allows the pusher to rotate in the direction. Thus, the shaft is always rotated when the pusher is depressed.

Title: Automatic temp. recording appts. for living tissue - uses stored value as reference for following measurements allowing side-by-side registering
Inventor: REEH JOHANN JOST DIPL ING DR
IPC: A61B5/01
Filed: 1979-10-23
Abstract: The automatic recording appts. for registering temp. values includes a digital control, a memory and a stepping motor. It is programmed so that several measuring result sequences can be recorded offset to each other. This enables the first measurement or sequence to appear next to the second and third etc. A measurement value derived within a measuring sequence is retained by storage. All subsequent measuring points are then recorded as difference values. The impulses for the stepping motor when winding back the registering paper are kept greater than the summed impulses used for the forward-running measuring mode. The stored first value can be removed during a measuring sequence and replaced by a selected, stored intermediate value to serve as the reference value for the following measurements.

Title: Moulding shaped plastics panels - in two=part mould having parting line extending from edge of panel
Inventor: NIELSEN HEINE BITSCH
IPC: B29C45/26
Filed: 1980-05-06
Abstract: One piece shaped plastics panels are produced in a two part mould one part of which defines the outside of the panel and the other part the inside, and the parting line of the two parts extends away from the edges of the mould cavity initially as flat surfaces substantially at right angles to an angles to an edge of the panel, and finally as surface sloping towards the exterior of the tool. Particularly moulding plastics guard panels for machine parts. Closing and assembling construction is completely tight and able to absorb the outward forces occurring during moulding, and the tool can be smaller and used in smaller injection machines, therefore the moulding appts. inexpensive and the price of the panels low.

Title: Emergency fire escape lift for building - uses hydraulic pump and pressure accumulator to store energy during lowering for returning cabin
Inventor: KRUPKAT OTTO DIPL ING
IPC: A62B1/00
Filed: 1980-09-10
Abstract: A cabin of light fire resistant structure is stored in readiness e.g. at a balcony. For use the cabin is shifted outwards. During the lowering motion with a person or goods in the cabin, the uncoiling of a cable (10) operates, via a cable drum (2), a hydraulic pump (4) taking fluid from a reservoir (5) and pumping it into a hydraulic storage vessel (7) fitted with a gas cushion, so that pressure is built up as the pump continues to deliver fluid. When the cabin reaches the low level destination and the load is removed, the stored pressure energy from the vessel (7) is used to operate the pump as a turbine. This rotates the drum to wind-on the cable and return the cabin to its former high level position.

Title: Sound editing for cine film and video tape - addressing each picture frame and correlating to start address of each sound track
Inventor: VYDRA ALAN
IPC: G11B27/028
Filed: 1980-10-13
Abstract: The sound track sections are stored in a memory with the start and end of each track linked to a frame address on the video track or on the film. When the film is edited the new addresses are entered and the sound track updated. The vision track can be played back, in conjunction with the edited sound track to provide a uniform performance. The system allows simple sound editing without danger of loosing track sections through cutting. After editing the sound control equipment re-aligns the sound tracks so that correct synchronisation is obtained, e.g. between atmospheric sounds, background music, speech, noises off.
