Title: Threaded stay bolt or screw - has smaller central smooth section and wider threaded section at one or both ends
Inventor: KAUDERER ALFRED
IPC: F16B5/02
Filed: 1976-12-23
Abstract: Threaded stay bolt or screw has a back cut smooth bolt part between its threaded section and its head. The dia. (d) of the smooth bolt part (7) is at least equal to or smaller than the core dia. (x) of the threaded part (6). The length of the threaded part (6) is approx. equal to the outer dia. of its corresponding thread (5). The structure of the bolt is such that it is resistant to vibrations, inhibiting their formation, and lessening their transmission. It can be produced with a head (3) and a long threaded section at the opposite end, or two threaded opposite ends of equal length, with a long central smooth section.

Title: Automatic variable speed washing machine transmission - has planetary gearing with hollow wheel braked by ring magnet
Inventor: LOOK GUENTER DIPL ING
IPC: H02K7/10
Filed: 1977-09-14
Abstract: A drive with a range of speeds for washing and centrifuging in an automatic washing machine consists of a motor which can be coupled through a reduction gear to the washing drum, and a transmission with >=1 centrifugal coupling coaxial with the motor shaft. The transmission includes a planet wheel drive, the hollow wheel of which is freely rotatable. During changeover to a different speed, it is braked by a ring magnet. As acceleration commences and the coupling slips, the magnet is switched off. The magnet is connected during washing to the corresp. winding of the motor, and to facilitate starting the magnet is energised after a slight delay. Efficiency is increased, prodn. costs are reduced and changeover noises are to a large extent eliminated.

Title: Driving and control of electric loads - involves central microprocessor which sends new operational states to loads, and receives messages on new actual states
Inventor: DIESING WOLF
IPC: B60R16/02
Filed: 1977-09-30
Abstract: The loads are connected to a central microprocessor. The connection is achieved through a ring control system consisting of a supply line, a clock line and a signal line. Each load is recalled by the multiplex method during its allocated periods, and it receives during a writing phase the operational state signalled on the signal line (7). The new established state is signalled back to the microprocessor for evaluation during an immediately following reading phase.

Title: Laminated serving tray with slip-proof surface - comprising several superposed melamine-impregnated or -coated sheets of paper plus top ply of PVC-coated fabric
Inventor: WERNLI PIERRE
IPC: A47G23/06
Filed: 1978-01-31
Abstract: Mfr. of a non-slip serving tray comprises stacking several sheets of paper which have been coated or impregnated with heat-setting resin, on top of one another; superposing a textile covered at least on its uppermost surface with a porous thermoplastics; and compressing the resulting semi-prod. in a mould, with application of heat, in such a way that raised portions of the top ply are converted, by polymerisation into a synthetic rubbery material and the whole assembly is moulded into its final, intended, shape. Specifically, both the textile and the thermoplastics layer are perforated. The thermoplastics is suitably PVC. The top ply is free from bubbles and voids. These tend to form, in prior-art processes owing to gases and vapours being entrapped during polymerisation. The process, as claimed, ensures that the prod. has uniform, non-slip, surface of pleasing appearance.

Title: Manipulator for stripping metal mould with refractory lining - for sepn. of cope and drag, and ejection of casting into drag
Inventor: TEPLINSKY ANATOLY DAVIDOVITSCH
IPC: B22D29/04
Filed: 1978-04-24
Abstract: The mould contains air holes, and consists of a cope and drag with horizontal joint line; and the mould is fed along a roller track until it is aligned on a hoist. The hoist lifts the mould so that a clamp on each pillar of a portal can mate with the cope. The cope is held while a set of piercing rods is pushed through the air holes to clean the latter and also to push the casting into the drag; the hoist then lowers the drag onto the roller track for transport to another work station. The piercing rods are amounted on a common plate driven vertically by a work cylinder mounted on top of the portal above the hoist; and one clamp can be rotated by a gearbox to turn the cope upside down, i.e. through 180 degrees on the common axes of the clamps. Savings in labour and space are achieved when removing ferrous metal castings with wt. =300 kg and dimersions >=1 metre.

Title: Sewage treatment - for separate extraction of sinking, floating and suspended particles by aeration and restriction
Inventor: ABEL GUENTHER
IPC: B01D21/00
Filed: 1978-07-22
Abstract: In a basin for the treatment of sewage, a first aeration zone, followed by inclined baffle plates, terminates in a restriction where worm conveyors for the extraction of the sinks are located. The next enlarged section houses a floating steel plate conveyor for the collection and extraction of the floats. A second restriction leads to another aerated zone with a conveyor for the extn. of the particles in suspension. This results in the separate extraction of sinks, floats, and suspended particles which remains highly efficient even when the flow rate is greatly reduced.
