Patent DE-2729987-A1 (DE)
Title: Vibrating toilet seat for relief of constipation - has motor operated vibrator attached to pan or wall with mechanical link to seat
Inventor: WOLF GUENTER
IPC: A47K17/00
Filed: 1977-07-02
Abstract: The toilet seat is actuated by a vibrator such as an eccentric, which can be attached directly to the toilet pan or to a wall and then connected to the seat by a rod. To ensure sufficient freedom of movement of the seat the latter is mounted on rubber-like wedges or rollers on the edge of the toilet pan where it is guided by guide pins and/or guide grooves. The vibrations can be regulated by means of a potentiometer control which is arranged so that the seat can be raised freely with the lid and sits firmly on the edge of the pan. The vibrations are thus produced either directly by an a.c. motor via a transmission system or by an eccentric which is attached to either the motor direct or to the vibrating seat.

Title: Multiple row roller bearing - has elastic location ring to prevent separation of bearing rings before installation
Inventor: MUELLER BERNHARD
IPC: F16C19/28
Filed: 1977-10-12

Title: Isobutyraldehyde-phenol! resins - made by condensing the components using an acid catalyst and distilling off the unused aldehyde
Inventor: REUTHER WOLFGANG DIPL CHEM DR
IPC: C08L61/06
Filed: 1978-02-10
Abstract: Isobutyraldehyde-phenol polycondensates are made by condensing isobutyraldehyde (I) with a phenol (II) in a ratio (I)/(II) of 0.6-0.9:1, in the presence of an acid catalyst comprising a phosphorus halide, H2SO4, an aromatic acid or HCl. Excess (I) is then distilled off. The reaction is carried out either by adding the (I) gradually to the (II) according to the conversion, until excess (I) has been added, or the (I) and anII) are added simultaneously to the reactor or are previously mixed. Use of the stated catalysts and conditions allows poly-condensates of (I) and (II) to be made without the formation of large amts. of low molecular material, as in previous processes. The prods. are useful tackifiers in unvulcanised (natural)rubber, as components in adhesives, as sand core binders and as binders for wood fibre boards.

Title: Mould and punch for thermoplastics film components - has cutting plate, retaining ring, spring-loaded film positioners and ejector preventing film being cut during moulding step
Inventor: MERKLINGHAUS HORST
IPC: B29C51/32
Filed: 1978-03-04
Abstract: Tool for shapic and subsequent punching-out thermoplastics film parts is claimed, the upper part of which has a first surface for the film and a cutting plate whilst the lower part carries a second clamping surface, a cutting punch, the mould located in it, and a mobile ejector associated with the mould. One of the clamping surfaces is located in an axially displaceable mount for positioning the film, e.g. with the aid of springs, both during the moulding and during the punching steps. An axially displaceable clamping ring with first clamping surface concentrically surrounds a collar of the cutting plate sitting ont he upper part of the tool and is sealingly lined against the collar. It can be adjusted, by means of the springs with its clamping surface in front of the cutting edge of the cutting plate. The (cutting) punch is concentrically arranged at the lower part of the tool within a springingly supported retaining ring carrying the other clamping surface. The cutting plate (for the punching step) can be moved, with clamping ring supported by retaining ring, with its collar in direction of the retaining ring. Cutting edges of cutting plate and cutting punch are kept at safe distance from the film during the moulding step, ensuring that they cannot, at this stage, penetrate into the film.

Title: Label dispenser with printing mechanism - is actuated by roller pressing label into position on item using ratchet and gear drive
Inventor: VOLBACH HANS
IPC: B65C11/02
Filed: 1978-08-07
Abstract: The label dispenser with a printing mechanism has a mounting in the housing for a roll of carrier strip with adhesive labels.
