Title: Safety system protecting paper cutting machine - has acceleration sensor, compensation drive and tachometer with differentiator for preventing overloading
Inventor: GOPPERT ERICH DIPL ING
IPC: B26D7/22
Filed: 1975-12-05
Abstract: In the safety arrangement for a transverse paper cutter the feed and cutter unit drives are synchronised. Between the cutters and cutter drum is arranged an adjustable compensation drive which generates a speed limiting signal for feed drive when cutter speed changes and allowable mechanical loading is reached. An acceleration sensor (12,13) is fitted on the cutter drum. The signal is generated by the connected analysing circuit (14). This system consists of a tachometer for generating signals. A monitoring circuit (17) senses the presence of tacho system signals and also those from an associated circuit (15).

Title: Pressure jet massage unit with fluid operating medium - has flexible base which contacts body section being massaged and medium heating and circulatory system
Inventor: GRASSKAMP KLAUS-DIETER
IPC: A61H23/04
Filed: 1976-01-16
Abstract: A pressure jet massage device is constructed such that a fluid or gaseous material (air) is pumped into a container under pressure. The fluid or gaseous material acts as a flexible or elastic base surface within the container which rests on the surface of the flesh section to be treated. A pump system is provided to remove the material from the container and the material is then fed through a heater before being re-passed to the massage device. A constant circulation of warm medium of regulable temperature is thus fed to the massager.

Title: Current supply equipment for distance supplied line repeaters - uses phantom circuit of two balanced lines with wire connected to resistors centre tapping
Inventor: PICHLMAYER ERWIN DIPL ING
IPC: H04B3/44
Filed: 1976-02-04
Abstract: Repeaters consist of a preequaliser and an active amplifier section in a balanced line. Supply d.c. current is fed in equal parts through a phantom circuit of two balanced lines to the respective repeater. A wire is connected to a centre tapping of two matching resistors connected in parallel to the repeater input. It is split in two by the resistors and carried by transmission line two wires to the output of the next repeater so that a supply d.c. circuit is produced. Two resistors in series with each other are connected in parallel with the output of each repeater and with the input of the active section (2). Their centre tappings are directly connected with each other, so that a second supply d.c. circuit is provided. Voltage drop between a repeater output and the input of the active amplifier section (2) is smaller than voltage drop in the first supply d.c. circuit.

Title: Flame effect yarn spinning process - uses separate feed unit to deliver effect fibres at irregular intervals to open:end spinning unit
Inventor: BARRE HAIDER ABUCAR
IPC: D01H4/32
Filed: 1976-04-22
Abstract: The additional fibre material to give the flame effect is fed at irregular intervals into the spinning chamber without crossing the sliver feed. The effect fibres are then combined with the sliver fibres to be twisted together into the yarn. System allows a variable effect to be achieved in the yarn, giving a wide variety of yarns at least equal to the range of other spinning processes. No additional controls are required to determine the speed of sliver and effect fibre feeds.

Title: Flat cable with parallel conductors - which are embedded in insulation and having another dielectric for reduction of cross coupling in communications signals
Inventor: GUERKAYNAK ERDAL DR ING
IPC: H01R13/658
Filed: 1976-05-20
Abstract: The flat cable has a number of parallel conductors embedded in insulation and another dielectric for reduction of cross-coupling in communications. The dielectric constant of the insulation is low and that of the dielectric is high. The dielectric material is placed at intervals along the flat cable (1) in the shape of rings or on one side in the shape of strips or beams. The distance of the rings (4) from one another and their dimensions depend on the dielectric constant of the material used. These rings (4) obtain the same compensation of the low dielectric constant of air outside the insulation (3) as the known continuous layer.
Patent DE-2625990-A1 (DE)
Title: Small spring loaded brake - has electro-magnetic release with armature with spherical end to control air gap
Inventor: BRINKMANN KARL-ERNST
IPC: F16D59/02
Filed: 1976-06-10
Abstract: The shaft (5) of an electric motor is provided with a disc brake actuated by the spring (9) and released by the armature (8) controlled by the electro-magnetic spool (1). The end of the armature is of spherical form (11) and matches the recess (12) on the spool housing (2). When the brake lining (6) wears during use, there is a corresponding increase in the air gap with conventional electro-magnetic brakes which reduces the magnetic force. With this design of armature and spool housing, the increase in the air gap (14) is less than the reduction in thickness of the brake lining (6) and so the necessary magnetic force is maintained despite lining wear.
Patent DE-2627238-A1 (DE)
Title: Transport mechanism for automatic multiple liq. analyser - has holders for analysis vessels stacked in vertical shafts, movable from first to second shaft
Inventor: KELLER WALTER

Title: Oil or gas burner circuit with emergency trip - generates long and short safety delays for restart and flame failure
Inventor: SCHWARZ SIEGFRIED
IPC: F23N5/20
Filed: 1976-11-24
Abstract: The oil or gas burner circuit ensures disconnection when disturbances occur in the burner system.

Title: Nonwoven felt mfr. - uses needles to force card web through a funnel feed
Inventor: SIEVERS KLAUS
IPC: D04H1/46
Filed: 1976-11-25
Abstract: In the mfr. of a non-woven felting material, a machine is used with a feed funnel and needles move in and out to force the card web through the funnel in the plane of the passage through the compression zone.

Title: 2,5-Bis-tri:bromo:methyl-1,3,4-thiadiazole prepn. - by brominating 2,5-di:methyl-1,3,4-thiazole in organic acid, useful as e.g. flame retardant for polystyrene(s)
Inventor: FLEIG HELMUT DIPL CHEM DR
IPC: C07D285/12
Filed: 1977-02-02
Abstract: (I) is made by brominating 2,5-dimethyl-1,3,4-thiadiazole in the presence of an organic acid. (I) is useful as a flame retardant additive in styrene polymers; as an adhesion promoter; as an intermediate in the prodn. of dyes; and as a phosphorescent marking agent for plastics. The process gives high yields of (I), largely free from dark coloured highly brominated by-prods. which have a deleterious effect on the flame retardant properties of the compsn.

Patent DE-2716251-A1 (DE)
Title: Lifting rod for inserting curtain runners in tracks - has insert head allowing automatic positioning of runners without manual pressure
IPC: A47H13/00
Filed: 1977-04-13
Abstract: The lifting rod used to insert curtain runners (3) into an opening on the underneath of the curtain track has an insert head with a lower contact face (10) which contacts the underneath of the rail. Seen from the insert direction (4) of the runners this face is on the front of the head. An upper contact face (11) which is pressed against the upper side of the lower flange of the rail is on the back of the head. When the lifting rod and head is inserted in the entry gate (14) of the rail it is automatically held there since the centre of gravity of the rod is behind the upper contact face (11) seen from the lower face (10). The upper contact face thus forms a kind of point of rotation so that the centre point of the mass presses the entire rod and insert head against the underneath of the curtain rail so that the pressure no longer has to be applied by hand. The entry gate to the curtain rail can be both swivelled and displaced along the track to allow easier insertion.
