Title: Dyeing of textiles, fabrics, fibres, etc. under part vacuum - ensures quick, uniform dyeing using low energy (PT 10.5.77)
Inventor: D ALCANTARA ANTONIO VICENTE MO
IPC: D06B3/20
Filed: 1977-04-02
Abstract: The dyeing of textiles of natural and/or synthetic fibres or, in the form of wovens, knitteds, spools, ropes, rovings, or raw fibres, is carried out under conditions of partial vacuum. The working temp. is maintained constant, having regard to the b.pt. at the degree of vacuum prevailing. The temp. is first of all held in the zone of the boiling point, and when the partial vacuum is removed, the temp. is raised very quickly. The goods are very quickly soaked and then dyed. The dye liquor penetrates uniformly and quickly. The fixing of the dyestuffs takes place rapidly and there is no down-grading of delicate materials. Energy consumption is also reduced.

Title: Telephone exchange with central control - has monitoring devices in which tolerances for kinds and number of failures can be set
Inventor: ABEL REINHOLD DIPL ING
IPC: H04Q3/545
Filed: 1977-04-07
Abstract: The exchange has at least two central control units regulating switching and connecting circuits with two connecting systems between control units and controlled devices, over which the necessary data are exchanged between the control and controlled devices. Functions of one central control unit can be replaced by those of the other. A monitoring device is allocated to each central control device. The two monitoring devices are interconnected by a central monitoring line through which failure or return to operation of one central control unit is signalled to the other monitoring device. Different tolerance limits for kind and/or number of error signals can be set in the monitoring devices. When a central control unit fails, it can be called back to operation by its allocated monitoring device with changed tolerance limits.

Title: Multistage evaporator for desalination of seawater - in which throughput can be halved without alteration of press. and temp.
Inventor: HOFSTEDE MARINUS JOHANNES
IPC: C02F1/06
Filed: 1977-04-12
Abstract: In a multistage flash evaporator, a channel in the form of a crevice connects the feed point of a stage to the vapour offtake point. The stage has two sections. One has a cross-section rsembling that of a snail shell and evaporation occurs here. The other is sack-shaped and is primarily a transport zone for concentrated liquor. The evaporator is esp. used for deslination of sea water. The throughput of the unit can be reduced by 50% of the design rate without variation of stage pressures and temps. No mechanical regulation of flow in the unit is necessary. Vapour is produced differentially so that no disentrainment equipment is needed and the press. drop in the vapour offtake line is minimal. The residence time in the unit is short.

Title: Paper feed mechanism for typewriter - has platen with paper guide which is removable for access by travelling printing head
Inventor: JOHANNSEN FRED ING GRAD
IPC: B41J13/16
Filed: 1977-07-09
Abstract: The paper feed mechanism for a typewriter has a cylindrical platen (3) provided with two guides (11, 14) so that paper can be fed downwards under the rear and bottom of the platen and upwards over the front and top of the platen. Between the two guides there is a gap for access by a printing head (9). To make it possible to close the gap so that a new sheet can be fed into the machine without failing to enter between the platen and the second guide, the gap can be closed by a further guide element (1). This is moved into position when the head is at the end of its travel.

Title: Piston pump for low m.pt. liq. metals - has toroidal ring to provide piston-cylinder seal despite differential thermal expansion
Inventor: OTTO HEINRICH
IPC: F04B53/14
Filed: 1977-08-04
Abstract: The pump has a piston (10) carried on a rod (8) reciprocating in a cylinder (1). The piston is made from upper and lower discs (12, 13) held together by axial studs (15). The disc hold a toroidal ring (20) of flexible material between them.

The seal between the piston and the cylinder is made by a toroidal ring. The piston rod (8) is hollow and its bore communicates with the space (21) inside the toroidal ring. Air under pressure is pumped into this space to maintain the seal at different degrees of thermal expansion.

Title: High temp. bleaching of cotton with alkaline hydrogen peroxide baths - contg. emulsified fatty alcohol deriv. as stabiliser, and surfactant(s)
IPC: D06L4/12
Filed: 1977-09-28
Abstract: The H2O2 is stabilised by the addn. of an emulsion contg. (a) fatty cpd. capable of forming organic hydroperoxides, such as fatty alcohols with straight or branched chains and derivs. of these contg. ether and/or keto gps., and (b) anionic and/or non-ionic surfactants which have a high wetting and emulsifying power, and which hold the cpds. (a) in emulsion. The emulsions have good stabilisation of peroxide bleaching compsns. of the type which are applied to cotton and heated to temps. of >=100 degrees C to bleach it. The emulsions are used to replace the alkali(ne earth) silicate stabilisers used prevously, which can lead to the formation of a ppte. of silicic acid cpds. on the pleached goods and on the treatment appts. This gives prods. with a hard handle, while the incrustations on the appts. are hard to remove and may cause damage to the fabric. The emulsions also promote rapid penetration of the bath into the fabric and retard the splitting of the H2O2 molecule at high temps.
Patent DE-2744447-A1 (DE)
Title: Loading and unloading kiln cars with ceramic ware - using one overhead crane requiring only limited floor space
Inventor: KELLER WERNER
IPC: F27D3/00
Filed: 1977-10-03
Abstract: The cars carrying baked ceramic ware travel along a railtrack (1), until they reach a bridge hoist located above track (1) and a parallel track (2), along which a row of pallets travel. The hoist picks up the baked ware from one car, and carries it transversely so the ware can be lowered onto an empty pallet, which is then moved along track (2). A palleT, on which dried but unbaked ware is mounted, is then moved under the bridge so the ware can be transferred to the empty kiln car; and the cycle described is then repeated. Loading and unloading of the kiln cars can be rapidly carried out at the same working zone, where only a very small amt. of floor space is needed.

Salt solution or other fluids for the heat pump are directed directly through this concrete heat exchanger. The structural steel and heat exchanger pipes are installed as a unit which is embedded in concrete.

Title: Electric motor driven roof ventilator - has system of cooling air guides and auxiliary blades between motor and rotor
Inventor: PETERS WILFRIED
IPC: F24F7/02
Filed: 1977-12-03
Abstract: The roof ventilator has a frame (3) supporting an electric motor (9) with its bladed rotor (4) below. The fan shaft (10) in this zone is enclosed by a heat insulating disc (11) with a central air gap (12). This forms a path for cooling air sucked from outside to reach the rotor for discharge sideways. This flow is assisted by an auxiliary rotor with radial blades (14) located above the disc (11). Above this disc is a parallel sheet (19) forming a space (20) housing the auxiliary rotor, with a central opening through which air is drawn downwards. Air is also drawn in through upper guides (16) to pass baffles (17) which directs the cooling air over the motor casing 18).

Title: Seat belt slack control mechanism - has belt guided along concave surface working together with rotary blocking vane
Inventor: FIALA ERNST PROF DR TECHN
IPC: B60R22/19
Filed: 1977-12-23
Abstract: Tge mechanism adjusts the belt on the user's body with a preselected slack. The active part of the mechanism consists of a concave guide surface (3) along which the belt (21) is guided when it is coiled off the spool (1). The guide surface (3) and the belt work together with a two-vaned blocking device (5) which is seated rotatingly on a shaft (4). The blocking device works in such a way that when one of the tip edges of the blocking vane rests against the upper region of the concave surface, offcoiling of the belt is possible, but a retracting movement is blocked by the edge of the vane clamping the belt against the concave surface. The position of the vane and/or length of the offcoiled belt is controlled by an actuator motor, receiving commands when to block the belt from a circuit controlled by a system of switches by which the length of slack can be selected by the user.
