Title: Hot air oven for fibre and plastic stretching - having double air passage to balance out temp. differences
Inventor: SCHEWIOR GOTTHARD
IPC: F27B9/10
Filed: 1976-04-02
Abstract: Hot air oven consists of upper and lower sections with a passageway between them through which a continuous length of material for treatment is passed. This passage has inlets and outlets for the introduction and removal of hot air. This consists of a double circuit system with a single air heater and fan mounted below the oven. The treatment channel is surrounded by an air passage down which the hot air is first passed before it issues into the main channel. Both sides of the oven are fed from the one fan via ducts containing dampers so that the flows can be balanced. The suction ducts combine to recycle to the fan inlet. Of use in the continuous stretching of synthetic fibres, ropes and plastic sheets to increase the strength. The problem with existing ovens is poor temp. distribution. The oven gives much improved distribution recycling the air through a common fan and heater.

Title: Chrome pigments for paints and enamels - coated with zinc metaphosphate to increase resistance to sulphur dioxide
Inventor: DOBSON DERRICK CLIFFORD
IPC: C09C1/34
Filed: 1977-02-16
Abstract: Improved chrome pigments are made by the simultaneous treatment of an aq. suspension of a chrome pigment with (a) metaphosphoric acid or one of its water-soluble salts; and (b) a water-soluble zinc salt. Aq solns. of (a,b) are pref. mixed with the suspension, esp. by their gradual addn. at the same rate of flow using a mixing temp. of 65-90 degrees C, and pH 5-10. The molar ratio, methaphosphate ions:zinc ions is pref. 2:1, and the addns. of the two solns. (a,b) pref. provides 0.5-15 wt.% zinc metaphosphate wrt of wt. of the untreated pigment, esp. 2-10 wt.%. The pref. cpd. (a) is sodium metaphosphate. After brief agitation, and possible pH adjustment to 7, the pigment is isolated. Prior to the addn. of solns. (a,b) the pigment may be treated with other, conventional agents used to improve its properties. The pigments may be used on various chrome pigments used in paint, e.g. industrial stoving enamels; alkyd resin paints; melamine-formaldehyde and acrylic paints; melamine-formaldehyde and acrylic paints; and in many plastics, and in many plastics, e.g. epoxy resins, PVC, polythene, polystyrene. The coating of zinc metaphosphate greatly increases the pigments resistance to SO2.

Title: Automatically released railway vehicle holding brake - has friction coupling between wheel shaft and ratchet wheel
Inventor: SCHELLE AXEL DIPL ING DR
IPC: B60T15/60
Filed: 1977-03-18
Abstract: The railway rolling stock holding brake, serving as an additional brake for holding the vehicle in position, has a ratchet wheel seated on a wheel-set shaft, with a locking lever for laying into the ratchet wheel. Between wheel-set shaft (2) and ratchet wheel (3) there is a friction coupling which releases itself after a prescribed degree of turning between them both. This friction coupling is in the form of a ring (5) and can be formed so as to be self-releasing when a prescribed max. temperature is exceeded, and for this purpose it may incorporate a thermostatic switch. An assembly can be fitted to provide for activation of the friction coupling by the relative movement between shaft and ratchet wheel.

Title: Pickling meat prods. with brine in rotary vacuum drum mixer - without prior injection of brine or surface scarifying during mixing
Inventor: THIRODE PIERRE
IPC: A23B4/02
Filed: 1977-03-21
Abstract: The prod. is first perforated deeply with a number of holes made by the insertion of narrow cutting blades. Mixing is then carried out in the presence of brine without using any axially displacable agitator independent of the mixing vessel and without using any surface scarifiers during the mixing operation. The mixing vessel is pref. a rotary cylindrical vessel on a horizontal but inclinable axis. One end of the vessel has an aperture with a removable lid which is secured to and sealed to the rim of the aperture by atmos. pressure while a vacuum is maintained in the vessel throughout the mixing stage. Ther is no need for prior injection with brine. A greater quantity of brine can be diffused into the tissues than previously. The quantity of brine can be closely controlled. Vacuum can be 'broken' several times during processing to induce diffusion of brine into the tissues.

Title: Inlet valve passage for IC engine - has insert with guide blades to impart turbulence to entering mixture
Inventor: BOLZMANN JOERG DIPL ING
IPC: F01L3/06
Filed: 1977-04-13
Abstract: The engine has a cylinder head (1) with a passage (2) for air inlet to each cylinder. The end of the passage has a valve seat (3) on which a mushroom headed poppet valve (4) closes.

Title: Transmission jerk measurement system in vehicles - uses torsion transducer in drive shaft connected to shock control device
Inventor: GROB FERDINAND DIPL ING
IPC: G01P15/00
Filed: 1977-06-18
Abstract: An IC engine (1) is coupled by way of a gear box (2) to the first part of a drive shaft (3). An intermediate torsion transducer (4) couples the second part of this shaft to the first part. The second part (5) of the drive shaft is coupled in the usual way to the road wheels (6, 7). A torsion measuring unit (8) is connected to the torsion transducer and also to a shock control device (9). The output of the shock control device is coupled in one embodiment to the gears and in another embodiment directly to the motor. On transmission of power from the engine, the wheels move, but the application of a shock by the shock control unit disturbs the motion and affects the travelling comfort. The shock is evaluated by the torsion transducer.

Title: Error correction system for transmission of graphic information - compares faulty line with adjacent lines and non-coincident part of line is shifted (NL 14.2.78)
Inventor: SCHAYES RAYMOND GEORGES
IPC: H03M5/00
Filed: 1977-08-02
Abstract: Signals represent the brightness of consecutive points during copy scanning in lines in the transmitter. Each line signals are converted into code words those number per line and length are variable. These code words are transmitted to the receiver together with line end signals and reconverted there into a series of signals corresponding to the series of picture points as transmitted. They are stored, and the number of picture points in a line is compared with a specified number. In case of a discrepancy a correction process is started. Signals of this line are compared with signals of the preceding and/or following line, and when a threshold for coincidence is not reached, and the rest of the faulty line is shifted, so that the line has the specified number of picture points.
