Title: Liq. level sensing device - has conductive surface on float to complete electrical circuit to sound buzzer at preset level
Inventor: JENDRO PETER
IPC: G01F23/70
Filed: 1976-12-21
Abstract: The alarm is for use with baths, and swimming pools the give an audible warning when the water reaches a predetermined level. A two-part enclosures has a battery and a buzzer in its upper section. Two electrical contacts from the upper section project into the lower section, one contact being coupled to the buzer and the other to one electrode of the battery. The other electrode of the battery is connected directly to the buzzer. A captive float retained within the lower section of the enclosure has an aluminium layer on its upper surface.

Title: IC engine valve shaft sealing assembly - has rigid PTFE quadrilateral ring abutting shaft along circular line pressed against wall of housing by soft rubber ring
Inventor: MUELLER HEINZ KONRAD PROF DR I
IPC: F16J15/32
Filed: 1977-02-08
Abstract: Sealing arrangement for mushroom valve shafts of I.C. engines includes a rigid PTFE sealing ring of quadrilateral axial cross-section and a resilient rubber tensioning ring which is located between peripheral and end walls of valve housing to press the sealing ring against hte opposite end wall of the housing.

Title: Flash evaporation for treatment bath recovery - using vapour recompression and recycle to balance evaporator load
Inventor: CHUTE RICHARD
IPC: B01D1/28
Filed: 1977-03-25
Abstract: A vapour recompression evaporator system has a housing surrounding a vapour chamber and means of introducing the feed. An extended surface inside the chamber, a compressor in teh vapour outlet is used to recompress the vapour and recover its energy and hold the chamber at reduced pressure. A compressor is in two parts, one rotating, the other on the stationary flights to effect the recompression. A jacket surrounds the chamber in which the vapour is recondensed to heat the liquid and provide the heat of evapn. Means of returning reconcentrated liquor back to the process and means of recycling condensed vapour as wash liquir are provided. Used esp. for use in reconcentrating plating solns. It permits recycle of the valuable metal ions etc. in the soln. and also provides a closed system for the wash liquor which reduces material usage, and effluent. Main problem with existing systems is control of recycle quality and the problem of keeping the system in balance when the process load varies. The system fulfills these functions, gives reduces mechanical maintenance and permits a more compact compressor construction.

Inventor: WIMBOECK GUENTER
IPC: F24C15/20
Filed: 1977-05-05
Abstract: The fat collector grid, through which the outgoing air charged with fat particles is drawn with the aid of a suction stream, comprises a number of lamellas (2a, 2b) which are arcuately curved in cross-section. These lamellas are arranged parallel alongside one another offset at distances in such a way that the longitudinal edges (3) adjacent to one another are of two adjacent lamellas (2a) of one series project in each case into the interior area of an opposite lamella (2b) of the second series. The longitudinal edges (3) of each lamella (2a, 2b) are drawn in such that the distance between their longitudinal sides is smaller than the maximum width of the inner area of the lamella. The longitudinal edges (3) project into the interior of the opposite lamella by an amount which corresponds to at least one quarter of the height of the lamella. The clear cross-section between two adjacent lamellas (2b) of the outflow-side series is equal to or greater than the smallest cross-section between the lamellas (2a, 2b) which is available downstream for the airflow passing through. The fat collector grid is intended in particular for large-scale kitchens. <IMAGE>

Title: Two component etchant for sawn semiconductor slices - esp. for removing damaged zones on gallium phosphide LEDs
Inventor: AENGENHEISTER JOERG DIPL PHYS
IPC: H01L21/306
Filed: 1977-07-08
Abstract: Etching of sawn semiconductor slices esp. for LED's to remove light-absorbing surface damage caused by the sawing operation is effecting using an etchant which consists of two media neither of which attacks the slice unless it is mixed with the other medium; and mixing only occurs on those zones where etching is required. The etchant may be a mixt. of (a) H2SO4 and (b) H2O2; but (a) KOH soln. and (b) K3(Fe(CN)6) soln. (PFIC) are pref. for etching GaP slices. The pref. method is to saw a GaP slice, then pour KOH soln. over it and allow the excess to drain. The slice is then immersed in PFIC soln. so the latter mixes with the KOH in the saw grooves; and this method may be repeated.

Title: Radial piston type hydraulic motor - has wide pistons in thick holder ring to take up gap between rotor and stator
Inventor: BERTRAMS JOSEF
IPC: F03C1/04
Filed: 1977-09-19
Abstract: The motor has a cylindrical casing with which a cylindrical rotor revolves on an eccentric shaft. Radial pistons are held in an outer ring round the rotor and caused to reciprocate by the movement of the rotor. The pistons run on rollers on the rotor and are sealed to it by sliding vanes. Their sides are supported in the outer ring by further rollers and they are sealed to the ring by circumferentially sliding vanes. The size of the pistons is such that they take up much of the gap between the rotor and stator and thus reduce consumption of liq.

Title: Utility vehicle braking system - has rear brake lines fitted with manual servo cylinders allowing selective operation for steering
Inventor: SIX RICHARD
IPC: B62D11/08
Filed: 1977-11-14
Abstract: The utility vehicle has a single brake pedal operating on the front and rear wheel brakes, as well as the trailer brakes, via a control valve. The rear wheels can be selectively braked for steering control. This is achieved by separate handbrake levers each of which operates on a servo cylinder in the brake lines to the rear wheels. The system uses the existing brake lines, and does not require any separate brake system for the steering brakes. In the servos special valves ensure that the normal braking effect can be passed to the wheels.

Title: Light-permeable building element for partitions, greenhouse roofs etc. - comprises polycarbonate, acrylic! or PVC flat flanged shallow tray with flat cover plate
Inventor: HERZBERG FRIEDEL
IPC: E06B3/66
Filed: 1978-01-19
Abstract: Glazing element comprises a relatively flat box composed of two opposite, spaced-apart, polycarbonate, acrylic or PVC panels connected and held apart by sidewalls. The panels are shaped so that >=1 forms a shallow tray with a flange, whilst the other panel is flat. Alternatively, both panels may be tray-shaped, but in either case form the flat box when superposed along the flange(s). Used where max. transparency is not critical but adequate light transmission e.g. good translucency, is sufficient, e.g. for fanlights in roofs, roofs of greenhouses, light-permeable partitions in offices or homes, cladding for balconies. The claimed article can be easily installed, using simply shaped profiled mounts which do not protrude objectionably above the surface of the box.

Title: Lift beam for hoisting container - has variable setting rotary hooks for picking up containers operated by shaft in beam
Inventor: PLUECKHAHN KARL-HEINRICH
IPC: B66C1/66
Filed: 1978-01-30
Abstract: The cross beam is for container transport and features rotary hooks, whose setting is variable for picking up and releasing a container. This arrangement is fully automatic and does not rely on the operator to vary the load requirements. An operating linkage for the hooks is fitted to a shaft which has an angle arm operated by drives. The operating shaft stands under a top dead centre device with a spring and this converts a movement pulse from the angle arm arrangement always into a 90 deg. rotation of the operating shaft.
