Title: Paper sheet stacking mechanism - has dividers inserted to form batches and auxiliary support for removal of bottom batch
Inventor: THORNTON JOHN NORMAN
IPC: B65H33/02
Filed: 1977-03-18
Abstract: The mechanism assembles and stacks material in sheet form e.g paper, cardboard etc. delivered continuously to a support, the stack being moved downwards as it increases. As the stack increases, dividers are inserted in it, splitting it into batches each with a set number of sheets. The lowermost batch is removed by an extractor mechanism, and while this is being done the remainder of the stack is held by an auxiliary support moved underneath it from a rest position. There can be a table moving up and down, and moved into the lowermost position for batch removal after insertion of the auxiliary support.

Title: Circular knitter lock - has cam arrangement to give casting on and off in each direction while needle cylinder is in the reciprocating mode
Inventor: NACKE OTTOMAR
IPC: D04B9/20
Filed: 1977-10-07
Abstract: In the lock mechanism for a circular knitter, where the stitches are cast on and off while the needle cylinder is in the reciprocating mode, beak type impellers are used to operate in any direction of cylinder rotation. These are operated together with pattern with at least one operating butt each and lock cams forming projecting and retracting surfaces for the operating butts. These are operative for both directions of needle cylinder rotation, so that on every second pass of the cylinder in its reciprocating action, the number of pattern slides is selectively increased or decreased. The design reduces the number of components needed to increase and decrease the stitches while the needle cylinder turns forwards and back, allowing the action in either direction.

Title: Soldering or de-soldering hard metal tips on saw blade teeth - using electric resistance heating of blade and tips
Inventor: BECK ERNST
IPC: B23K31/02
Filed: 1977-11-17
Abstract: The machine includes a contact plate(a) in which the hard metal tip is located, the plate(a) being connected to one pole of an electric power source(b). A clamp contains two jaws which are pressed against opposite sides of the saw blade; and at least one jaw is connected to the other pole of source(b), which is used for the resistance heating of the blade and the hard metal tip.

Title: Window cleaning apparatus - with pump supplying liquid to sponge containing ultra sonic generator
Inventor: COBARG CLAUS DIPL PHYS
IPC: A47L11/12
Filed: 1977-12-01
Abstract: Window cleaning apparatus consists of a container (17) for cleaning fluid with a lid (18) which houses a small pump. The pump delivers the liquid through a pipe (16) to a sponge. The sponge contains an inner dividing wall which shuts off the supply of liquid when the sponge is compressed and at the same time ejects the liquid already absorbed by the sponge over the window pane. In a further version of the apparatus the sponge houses a battery powered ultra-sonic generator which facilitates the removal of dirt from the surfaces being cleaned.

Title: Surface, shape, and flange groove scanner - has shutter moving with pointed probe to vary light from source incident upon two photodetectors
Inventor: SCHULZ WOLFGANG DIPL PHYS DR I
IPC: G01B11/00
Filed: 1978-04-28
Abstract: A scanning device for shapes, and flange grooves has a scanning probe whose movement produces an electrical signal proportional to the distance moved. The probe is connected to an aperture moving between a light source and two detectors. When the probe and aperture move the distribution of light falling on the detectors varies. The difference between the detector output signals is analysed to produce a signal approx. proportional to the distance moved. The scanning tip (1) is coupled to a shutter (2) movable between a light source (3) and two photo-detectors (4a, b) to vary the amount of light falling upon them. The difference between the two detector signals is measured.

Title: Brake disc mounting ring - has cup washers and necked bolts for mounting on wheel hub, with washers transferring loads between flanges
Inventor: SCHOERWERTH MATHIAS
IPC: F16D65/12
Filed: 1978-06-27
Abstract: A brake disc mounting ring (7) is attached to a wheel hub (1) by a series of necked bolts (33), mounted in holes (13, 15) whose pitch circle diameters (17) are slightly larger in the hub (1) than in the mounting ring. The bolts (33) thus lie at a slight angle to the central axis and their shanks are not in contact with the sides of the holes (13, 15). Loads are transferred from one flange to the other by cup washer assemblies (25, 27, 29, 31). This arrangement allows movement due to temperature expansion of the mounting ring (7) to take place, without damage to the bolts (33).

Title: A=D converter with two=way counter - has two opposite polarity reference voltages switched by comparator to voltage-frequency converter
Inventor: BAYATI ABUTORAB DR ING
IPC: H03M1/00
Filed: 1978-12-13
Abstract: The A/D converter has the bit outputs of two-way counter connected to the corresponding inputs of a digital comparator. The counter is connected to the output of a voltage to frequency converter receiving the analog input. The comparator compares the counter contents with the up-counters clock pulses. When the two-way counter contents exceed momentarily the up counter contents, the comparator produces a signal controlling the switch that applies reference voltages to the input of the voltage to frequency converter. Two reference voltages of opposite polarity are then available. The change-over switch connects either the one or the other to the voltage to frequency converter. The two references have the same magnitude.

Title: Insulation stripping method from cable end - uses insulation ring separated from cable insulation, in addition to stripped section, to hold cable cores when pushed to end (NL 15.7.80)
Inventor: WOELFEL KURT
IPC: H02G1/12
Filed: 1979-01-13
Abstract: The cable contains at least one insulated conductor of a number of stranded bare conductive wires. In the stripping process the insulation is cut in a presetable distance from the conductor end, and this insulation section is pulled off. In addition to the removed part a ring (6, 7) of the insulation is also separated and is shifted towards the end of the conductor (4, 5) and left there, while leaving the conductor tip free. Pref. the ring is narrow in relation to the removed part length. The end rins provide compact conductor tips for possible connection to plug pins, or socket contacts etc. They also form a safeguard against short circuits caused by roprotruding cable core wires. The formation of these rings is an easy replacement of core ends soldering, required by safety precautions.

Title: Opto-electronic measurement systems - comprises transmission with beam splitter and modulator connected to detector
Inventor: DAGEFOERDE HANS-GERD DIPL ING
IPC: G01D5/34
Filed: 1979-02-01
Abstract: Elimination of electrical interference on indication of transducers is achieved by sensing non-optical magnitudes with optical means. The conversion is carried out without external power supplies and the modulated beams is demodulated for the final indication of the measurement results. The transmitter (1) provides a beam, transmitted to a converter (6) where splitter (10) divdes the beam into partial beams (3, 4). Detector (9) receives partial beam (4) through coupler (20) for usage as a reference signal while partial beam (3) is subject to modulation by attenuation (7). The latter operates with a screen (11) moved across its path by a mechanical transducer (16), the Vee notch of the screen covering a smaller or greater area of the beam. Transducer (16) is driven by a bimetal strip controlling the discs of polarisation filter (17). Attenuation of the partial beam is detected by a unit (9) which provides indications.

Title: Small and slow AC sync. motor - has two separate magnetic paths for phase-shifted and non-phase-shifted magnetic flux
Inventor: MERKLE PAUL
IPC: H02K19/08
Filed: 1979-01-15
Abstract: The sync. motor has a coaxial stator coil half of whose stator poles are displaced in phase and located in the alternating field cycle. The non-phase-shifted magnetic flux of the stator and the phase-shifted magnetic flux of the stator outside the rotor have no shared iron path. The iron casing of the stator coil is doubled and a short-circuit-current sleeve is located between these two sheathing. Synchronisation is accomplished using stray magnetic flux. To this purpose, an extra pole tooth disc is on the rotor and a fixed pole tooth disc is arranged on the corresponding part of the housing.
