Title: Synthetic warp thread fault detection process - uses a dye bath for rapid immersion of initial thread length to mark fault to correct warping stage
Inventor: RELLENSMANN WOLFGANG DR
IPC: D06H3/10
Filed: 1976-02-04
Abstract: The threads are composed of continuous filament synthetic high polymer materials, particularly polyamides. Teh first 3-30 m of the warped threads are drawn into a warp knitter and knitted into a fabric. As the fabric continuously leaves the warp knitter, immediately it emerges it is given a rapid dyeing for fabric faults to be detected and marked. The process gives a rapid indication of faults which can be used for correcting the warping action to avoid striped effects and other unwanted characteristics.

The inserts fully protect the tundish from molten metal contact and preheating of the tundish is not required. After pouring, the tundish can be relined and put into service within 2-4 hrs., thus reducing the number of tundishes required. The inserts may be made of e.g. in one case a mixt. of 15 wt.% sawdust, 54 wt.% dolomite and 31 wt.% sodium silicate.
Patent DE-2618384-A1 (DE)
Inventor: KRAEMER ALOIS
IPC: B28B7/00
Filed: 1976-04-27
Abstract: In order to erect self-supporting floors, it is known to introduce concrete floor beams with a trapezoidal cross-section. They have at least one channel-type cavity (6, 7) extending in the direction of the longitudinal axis of the floor beam. If required, they may also have, on the trapezoidal sidewalls converging upwards, gutters (8, 9) running in the direction of the longitudinal axis. A shuttering is proposed for the production of floor beams (1) of this type. The shuttering has a transporting pallet, serving as shuttering base slab (10), and two side shutterings (12, 13) arranged thereon. Said side shutterings run upwards towards one another in the manner of a cone, corresponding to the trapezium angle, and can be raised and lowered. Furthermore, there is arranged at least one tubular shuttering core which forms the channel-like cavity (6, 7) and can be horizontally displaced, by more than the length of the floor beam, transversely to the movement direction of the side shuttering and parallel to the longitudinal extent thereof. Vibrating means (21, 22, 23) for compacting the concrete are arranged in the side shutterings (12, 13) and in shuttering boxes (16) which may be introduced if required. <IMAGE>

Inventor: HOEPNER THEODOR DR
IPC: D21C5/00
Filed: 1976-05-11
Abstract: Recovery of cellulose for newsprint mfr. from bagasse involves (a) preliminary moist removal of pith; (b) moist storage, opt. with the addn. of preservative and/or microbe cultures; (c) wet removal of pitch, opt. with addn. of chemicals, which (partly) remove the colouring matter present; (d) pulping to cellulose by the neutral sulphite process or another fibre-preserving and fibre-selective process, e.g. thermomechanical pulping; (e) completion of pulping by a mechanical hot pulping process; (f) washing, sorting and thickening and (g) opt. subjecting to a peroxide bleach.

Title: Electric connection between sliding door and wall - has cable with spring loaded support rolling during door movement
Inventor: HAGIN FAUST
IPC: H02G11/00
Filed: 1976-06-18
Abstract: The design for the support of cable during the sliding of the door reduces maintenance by fitting the support between the wall and the door. The spring-loading of the support roller prevents relative shifts due to wear. The flat cable (3) is secured to the vertical wall of the slide door (2) as well as to a holder bracket (5) of the wall (1). The cable forms an U-loop and remains in contact with both the door and the wall during all movements of the door. When the door is in the closed position, the main part of the cable bears against the wall bracket (5), while in the open position the cable rests on the door. Enhanced flexural stiffness of the cable (3) w.r.t. the horizontal axis is achieved with the spherical segment cross section of the support band (6) whose convex side faces the cable. The support band is connected to the cable by clips (7).

Title: Regenerative heat exchanger for very cold air - with frost formation prevented by hydrophilic film in storage mass
Inventor: SCHAAL GERD DIPL ING
IPC: F24F3/14
Filed: 1976-06-29
Abstract: A regenerative heat exchanger, partic. for air conditioning in buildings etc. has a rotor with a storage mass having a number of channels running from one side to another through which alternately various air currents flow when the rotor rotates. The storage mass effects the exchange between them of sensible and humidity heat, the mass has at least one metal corrugated tape and at least one film between its layers. This film is hydrophilic and non-metallic and largely determines the exchange of humidity heat. The corrugated tape however largely effects the exchange of sensible heat. The cross-channels in the tape, carrying the air currents, are bridged by at least one intermediate tape or are open to an adjacent tape layer and its internal channels. At least in the latter case the longitudinal axes of channels of alternate tapes are pref. at an angle to the longitudinal axes of the intermediate channels. The exposed inside surfaces of at lest half the number of channels and over more than half of their respective areas are made of hydrophilic film. System is energy saving and air flow is not seriously impeded by frost formation with air down to -10 degrees C.

Title: Safety noise protection equipment - has radiated signal outside hearing range converted to audible inside equipment
Inventor: NIKISCH HORST DIPL ING
IPC: A61F11/14
Filed: 1977-01-19
Abstract: The safety noise protection equipment allows acoustic communication between those working in very noisy surroundings, without harm to their hearing. An emitter radiates a signal outside the range of hearing, and this generates in ear protection equipment an audible frequency. This signal conversion is independent of the protection provided by the equipment. The latter can be arranged to provide even and maximum protection over the whole audible range, while the radiated signal can be ultrasonic.

Title: IC engine ignition timing adjuster - has vacuum actuated timing device which can be disconnected when engine reaches preset speed
Inventor: LOECK HARALD DIPL ING
IPC: F02P5/10
Filed: 1977-02-01
Abstract: The ignition timing adjuster is intended for a combustion engine with a thermoreactor in the exhaust manifold and with an ignition distributor. The ignition timing point is adjusted in the advance direction by a centrifugal force dependent regulator in response to the optimum adjusting curve of the engine. In the retard direction the adjustment is carried out in opposite direction by a device (2) responding to the engine vacuum. This device can be disconnected when the engine has attained a preset speed. The vacuum line (5, 6) to the retard adjuster pref. contains a speed controlled three-way valve (8) which provides connection to the intake manifold (7) at conditions below the preset speed. After the preset speed has been reached, the valve connects to atmosphere.

Title: Rectangular or square floor or wall plates - are extruded edgeways and impressed with cut pattern for ready separation
Inventor: EISENBACH KURT
IPC: B28B11/08
Filed: 1977-02-10
Abstract: The plant for making rectangular or square ceramic wall or floor plates is used especially for making split plates with ornamental shapes. These plates can be produced without waste and continuously, by a relatively simple system. A double flat strand of clay is extruded so that the strand is supported on its lower edge. The extruded strand is cut on one side to plate lengths. The required parting pattern is pressed on the sides of the plate to a depth which ensures that the plate can be used as a whole. The ornamental pattern can be pressed so that some cuts go right through the plate. Continuous production is ensured by guide system which delivers extruded plates to transporter. This guide system returns to the extruder for collecting the next plate.
