Title: Window-cleaning mop re-moistening device - has electrically heated steam ejector operated by pump lever on mop handle
Inventor: NAUTA WILHELM ING GRAD
IPC: A47L1/08
Filed: 1975-03-26
Abstract: The mop head has a ribbed (13) sole plate (2) over which a band of cloth or absorbent paper (3) is stretched between two spools (5, 6). A hand pump forces water-in limited quantities, as needed - through a nozzle (16) into an evaporation chamber (9) where the electric sole-plate heater (11, 12) turns it to steam for ejection through holes (10) in the sole plate on to the cleaning cloth. The sole plate ribs (13) consist of a raster of C-, V-, I-, or S-shapes and serve to spread the steam. The cold water supply may be contained in the mop handle or it may be in a separate container feeding into the handle.

Title: Bottle filling capping and labelling machine - has support surface interrupted to allow broken bottle bases to drop into bin below
Inventor: DULLINGER KARL
IPC: B67C3/00
Filed: 1975-06-19
Abstract: The bottle filling, capping and labelling machine has star wheel (5) feeding the bottles (4) past the rotary filling head (6) onto an intermediate star wheel (7) to the capping wheel (8). Then the bottles as fed onto a transfer wheel (18) feeding another supply wheel (12) for passing to the labelling device (16) and take-off conveyor.

Title: Froth beating appliance for confectionery industry - has perforated rotor discs alternating with perforated stator discs in vertical cylinder (NL170377)
Inventor: GOTSCH GUENTER
IPC: A23G3/14
Filed: 1975-09-15
Abstract: A whipping appliance to beat masses and solutions in the sweets and pastry trade consists of a vertical cylinder through which the mass flows in a downward direction. A motor driven axial shaft is equipped with perforated rotor discs which alternate with similar stator discs fixed to the cylinder. The greater number of shear points raises the frothing ratio and at the same time makes the load for the drive more uniform. The perforated discs can be readily exchanged for other hole sizes to achieve a different effect.

Patent DE-2549144-A1 (DE)
Title: Modified star wheel linking bottling plant component machines - adapts spacing between bottles to suit machine it feeds
IPC: B67C7/00
Filed: 1975-11-03
Abstract: The component machines of this bottling plant operate with the bottle differently spaced. In particular, the labelling machine requires them at a wider spacing than it would be economic to provide on the bottle-closing machine that precedes it. Instead of using a feed spiral, the machine may be connected by a star wheel with extra deep pockets. As the bottles move round this wheel, guides take them from deep in the pockets out to the pocket edge. Their angular separation remains unchanged, but they are moved farther from the axis of rotation, and so farther apart, as the labelling machine requires.

Title: Control circuit for windscreen wipers - has contact gap in control disc and single power supply lead
Inventor: ANDREI-ALEXANDRU MARCEL DIPL I
IPC: B60S1/08
Filed: 1976-01-24
Abstract: The circuit has only one power supply lead and is particularly intended for rear window wipers. The control disc (2) has a contact gap to indicate the parking position. The advantage claimed for the design is ease of fitting with no additional expensive components. In the main supply lead (6) there is a contact gap (4) between the on-off switch (8) and the sliding contacts (3,5) of the motor. The switching element (7) has a delay characteristic and the gap is just sufficient to ensure full circuit breaking. The switching element (7) has a contact (12) with its armature that allows hand operation and can therefore also act as on/off switch. The relay can be a thyristor. A further switch can be fitted to a bypass lead. This can be a bimetallic switch; a relay or a further thyristor.
Patent DE-2604433-A1 (DE)
Title: Knitted fabric mfr. - using sliding holders to form stitch and pass looped yarn through old stitch to reduce number of operating movements
Inventor: HOFMANN ULRICH
IPC: D04B39/00
Filed: 1976-02-05
Abstract: Stitches of teh new row are linked to the preceding row. The stitches are laid on a guide bed and hign in the requried length. The yarn is passed vertically through the stitch to form a losse loop. The hung stitch is released by sliding the holder in teh guide bed. The loose newly-formed stitch is caught and hung according to the required stitch length. Process reduces the five stages of conventional knitting to two including passing the new stitch through the old and releasing the old stitch while securing the new stitch. Replacement of the needles by a cylindrical holder allows a wide variety of stitch sizes to be executed without the complexity of controlling needle movements.

Title: Radiation absorption measurement in object plane - uses wedge shaped focussed beam passing through object
Inventor: KOWALSKI GUENTER DR
IPC: A61B6/03
Filed: 1976-02-13
Abstract: A beam of radiation passes through an object. it is measured by a number of detectors which - possibly after the radiation conversion to a longer wavelength radiation - generate a first signal depending on the radiation intensity. A scattering element is provided between the object (2) and detectors (3) which scatters the radiation (4) to directly adjacent detectors. The radiation is spatially modulated by the absorbing object.

Title: Tapered candles prodn. from cylindrical blanks - by successive dipping to increasingly greater depths
Inventor: INDERBIETHEN HERBERT
IPC: C11C5/00
Filed: 1976-03-18
Abstract: Tapered candles are produced from cylindrical blanks by several successive dipping operations into a bath with fluid candle material. Each operation is at a successively greater depth so that the finished candle is given a succession of partly overlapping layers of solidified candle material. Process saves time and material compared with the machining down from oversize cylindrical candles. The prodn. rate is faster than in casting operations.

Title: Punching stamping and rivetting appts. - has link which moves blank holder, holding blank against die during working stroke
Inventor: GARGAILLO DANIEL PIERRE
IPC: B21J15/10
Filed: 1976-05-06
Abstract: The appts. for punching, stamping and rivetting a blank work piece includes a tool holder for holding the tool, that is displaceable between an inoperative and an operative position; a blank holder for holding the blank that is also displaceable between an inoperative and an operative position; a die; and a link means linking the tool holder and the blank holder together. The link means is such that displacement of the tool holder from its inoperative position to its operative position during its working stroke causes the blank holder to be displaced from its inoperative position of its operative position thereby holding the blank against the die. The blank holder is kept in its operative position until the tool holder has been displaced at least sufficiently towards its inoperative position to disengage the tool from the blank and being such that thereafter the blank holder is also caused to return to its inoperative position.

Title: Systematic real coupling compensation - is for communications cables, cores of which have identification colour on insulation
Inventor: BIRKENSCHENKEL HARRI DIPL ING
IPC: H04B3/34
Filed: 1976-05-19
Abstract: The coupling compensation system is for communication cables, the cores of which have an identification colour on the insulation. The individual cores of each quad cable are identified by different colours. Specific intersection sequences in the connecting joints of the mfd. lengths of a section are provided for the compensation of the systematic couplings occurring on the cores of a quad cable owing to the various amounts of colouring. In a quad cable, two intersection positions (2, 3) alternate for compensating the systematic seal couplings. Alternatively, an intersection position remains the same. The interaction of colourings causes dielectric asymmetrics in the quad cable.

Title: Centrifugal pump with shaft seal - has auxiliary blades on back of impeller disc to improve sealing
Inventor: KRAEMER HERMANN
IPC: F16J15/34
Filed: 1976-07-20
Abstract: A centrifugal pump has an impeller (2) with curved blades on a shaft (3). There is a stuffing box or mechanical seal between the shaft and the pump casing. The back plate of the impeller disc has a set of auxiliary centrifugal blaes (8) on its back facing the back of the casing. The inlet of these blades is coaxial with and near the seal (5) and the outlet (10) discharges into the pump discharge volute. Working fluid flows radially inwards in the gap (9) between the auxiliary blades and the casing and is sucked from the seal area into the auxiliary blades to be added to the pump discharge. This circulation creates a liquid seal to ease the load on the stuffing box.
