Patent DE-2422406-A1 (DE)
Title: Tyre retreading or vulcanising mould - with tread sectors swinging radially outwards from one half-mould during opening
Inventor: ANTRAIGUE PIERRE
IPC: B29D30/06
Filed: 1974-05-09
Abstract: A mould, esp. for treading or retreading pneumatic tyres, comprises a pair of mould plates each supporting a lateral mould for a tyre wall and capable of moving along the axis of the tyre to open or close; the tread moulding sectors move radially outwards to release the tyre as the mould opens and, as the mould closes, return to their closed position by the interaction of oblique surfaces on the mould plates on the one hand and on the sectors themselves on the other hand. The sectors are pref. suspended from the upper half-mould of a vertical-axis mould, so that as the plates move apart the sectors swing outwards by their own weight; their outward travel is limited by stops or abutments, esp. bearing against a mould wall having limited movement relative to its supporting plate. The sectors may also be supported from the bottom half of the mould and during opening are forced apart by a spring which separates their supporting side mould from its supporting plate. Accurate opening and closure motions are thus obtd., causing no deformation of the tyre, which is esp. important in the case of radials.

Patent DE-2542998-A1 (DE)
Title: Evaluating circuit for SSB suppressed carrier signals - uses tape recorder for frequency adjustment when transmitter subcarrier not known
Inventor: HOERING HANS-CHRISTOPH DIPL IN
IPC: H04B1/30
Filed: 1975-09-26
Abstract: The evaluating circuit for single sideband HF signals with reduced or suppressed carrier, allows LF signals of sufficient quality to be produced from e.g. radio signals whose modulation sub-carrier frequency is not known and allows this to happen even with transmissions of short duration. The received SSB signal is stored using a tape recorder in its IF state before demodulation. The stored signals are demodulated by adjusting the frequency of the subcarrier until the required quality is obtained. The tape recorder (3) is connected between the output of a frequency converter (2) coupled to the IF stage output and the input of the demodulator (4). A second demodulator (7) supplied with the same subcarrier (5) as the first is connected directly to the converter output.

Abstract: The sytem for continuous drawing of tubes, is constructed such that there is an intermediate space present within the interior of the tube (1) in front of the drawing mandrel (3) at the same height as the drawing die (2). The space is formed by the cuffs (7, 8), the internal wall of the tube (1) and the curved surface (C) of the drawing mandrel (3). The space is filled with as large an amount of lubricant (9) as is practicable and this lubricant is used to lubricate the action of the drawing mandrel (3).

Title: Electron beam evaporation equipment for metals and other materials - with grid for protection of cathode
Inventor: MUELLER PAUL DIPL PHYS DR
IPC: C23C14/30
Filed: 1975-11-18
Abstract: Electron beam heating equipment has a grid surrounding the evapn. source to which a negative voltage greater than that to the cathode is applied so that the positive ions formed by evapn. flow to the grid and the cathode only receives a small stream so that its life is lengthened. The ions drawn to the grid can be used to measure the rate of evapn. and to control it to a given rate. The grid prevents damage to the cathode and thus lengthens its life.
Patent DE-2556713-A1 (DE)
Title: Flat roof edge and wall sealed joint - has parallel angled unit filled with elastic sealing mass and layered coating
Inventor: ROJAHN HEINRICH DIPL ING
IPC: E04D13/14
Filed: 1975-12-17
Abstract: The joint is for a flat roof with an outer coating comprising one or more layers meeting a rising wall face, esp. as in a fascia and where a thorough sealing and heat-insulating effect is necessary. There is an angled shaped unit, running parallel to the edge between wall and flat roof, with one arm surface standing out from the former and lying on the latter. Its second arm surface, facing the wall, runs out leaving a gap from this, to be filled with an elastic, deformable clinging sealing mass. With the first arm surface included, the flat roof is provided with its layered coating up to the level of the second arm's top edge. A moisture resistant layer may be applied to the rest of the rood surface, while the top layer of the coating is covered with a stone layer.

Title: Heater for screen wash water - with vehicle heater coupled to pipe through wash reservoir
Inventor: MAXIMOVIC PETER
IPC: B60S1/50
Filed: 1976-02-25
Abstract: The screen wash reservoir is fitted with a pipe through its centre, connected to the vehicle heater system. When the heater is switched on the heat tapped off through the pipe warms the washer water without any additional control from the driver. No defrosting additives are required to ensure efficient ice clearance. The system can be fitted to existing washers simply by boring two holes through the reservoir and sealing in the pipe with screw fittings and sealing gaskets. The pipe is connected either into the warm water supply to the car heater or uses some of the warm air supply from the heater fan.

Title: Ribbon tying arrangement for parcel wrapping machine - has ribbon clamps and hot blade to produce welded joint (NL090976)
Inventor: VAN DE BILT PIET ARNOLDUS
IPC: B65B13/22
Filed: 1976-03-05
Abstract: A packing machine has a tie ribbon dispenser which places a ribbon (7) around a parcel on table (2). The leading ribbon end is then held by clamp (14) so that, be tensioning the ribbon, a tight loop around the parcel is produced. The ribbon is then clamped at a second position so that the tension is maintained when a knife (17) cuts off the ribbon from the supply coil. A hot blade is now placed between the overlapping ribbon ends so that, after its removal, the ribbon is in a plastic state. The ends are then clamped together to produce a durable joint.

Title: Herbicidal (1,2,4)-triazinone derivs. - prepd. by reacting (4)-amino-(3)-mercapto-(1,2,4)-triazinones with phenoxy-acetyl isocyanates
Inventor: SIRRENBERG WILHELM DR
IPC: A01N47/36
Filed: 1976-03-30
Abstract: New 1,2,4-triazin-5(4H)-one derivs. are cpds. of formula (I), in which R is phenyl opt. mono- or polysubstd. by halogen and/or 1-4C alkyl, and R1 is 1-4C alkyl. (I) influence plant growth, and can be used as defoliants, desiccants, germination inhibitors and, esp. herbicides. The herbicidal effect is total or selective, depending on the rate of application. (I) can be used e.g. as selective herbicides in crops such as soya beans or maize, unlike known triazine herbicides, (I) have activity against grassy weeds. Application may be post- or (pref.) pre-emergence. (I) also have a development-inhibiting effect on various stages of insects. Specific cpds. (I) include that in which R is 2,4-dichlorophenyl and R1 is methyl. In an example, this is prepd. by reacting 4-amino-6-tert-butyl-3-methylthio-1,2,4-triazin-5(4H)-one in dry toluene with 2,4-dichlorophenoxyacetyl isocyanate in the presence of a catalytic amount of Sn(II) octoate.
