Title: Removal of chloride from flue gas before sulphur di:oxide wash - by scrubbing with acid liquid contg. calcium cpd. and carboxylic acid
Inventor: HOELTER HEINZ
IPC: B01D53/68
Filed: 1978-02-27
Abstract: Removal of chloride from flue gas before the SO2 wash is effected by inserting a scrubber operating with a liquor of pH 0.5-2.5, contg. (Ca(OH)2 or a Ca salt and (polybasic) carboxylic acid. The was liquor can be taken from the SO2, scrubber. Pref. clear liquor in taken from the clean water zone of the gravity sepn. zone and/or the overflow from the SO2 scrubber with low pH. The liquor circulation is controlled to maintain a pH of 0.5-2.5. The process is useful in the purificn. of waste gases from power stations burning coal with a high chloride content. Little or no SO2 is removed in the chloride scrubber, so that the liquor can be conc. to yield salt for strewing, binding dust in mines or thawing ice and snow. Alternatively, the salt can be briquetted with the dust from the electrofilter and a binder (cement) and dumped without causing environmental pollution.
Patent DE-2820044-A1 (DE)
Inventor: RIHM ERICH
IPC: A63D5/04
Filed: 1978-05-08
Abstract: On a control panel (62), a push-button is allocated to each player, so that the results of his shots, sensed by the sensing switches (64), and the number of shots are stored in a memory unit of a data memory (76). The data to be stored and the data already stored are displayed on a display panel (10). By means of such an arrangement, the results of the shots of each individual player are stored separately and can be displayed retroactively, especially at the end of the game, on the display panel (10). Each of the players can thus obtain a guide as to his achievements. <IMAGE>

Title: Drying roller with interchangeable scraper blade assembly - with pneumatic or hydraulic quick release mechanism for replacing blades
IPC: B01D33/00
Filed: 1978-09-19
Abstract: Roller dryer incorporates a blade running the length of the roller mounted on a knife board which is hydraulically tilted to bring the knife edge into contact with the roller. The blade of the knife assembly is mounted between a backing plate and a retaining plate, these being clamped together by means of bolts. The assembly is placed into position against the knife board and is held by means of hydraulic or pneumatic cylinders. To remove the assembly the pistons are retracted whereupon the knife assembly can be lifted out and replaced with another. To prevent the assembly from falling out when the pistons are retracted, the cylinder mounting blocks are preferably equipped with screwed pins the ends of which locate in recesses in the knife assembly backing plate. These pins can be screwed back by hand. The knife assembly can be rapidly exchanged manually saving the normal down time when a blunt blade has to be removed.

Title: Electronic alarm wrist watch - has change over switch between timing circuit and receiver driven by aerial
Inventor: HOLZER WALTER
IPC: G08B1/08
Filed: 1979-05-08
Abstract: The tripping circuit of the alarm in the electronic wrist watch is used for supervisory or signalling duties. The trip circuit is connected to a receiver featuring an aerial (5) as well as to the timing circuit of the watch. The switching between the receiver and timer is controlled by a change-over unit. The transmitter provides a modulated or coded signal processed by the decoder or demodulator of the receiver for driving the discriminator. This ensures the detection of present or absent modulated or coded data for driving the signalling circuit. Elimination of faulty operation of the tripping circuit is due to a counter, series-connected to the discriminator.

Title: Trigger circuit for gate-off thyristor - derives trigger power from controlled load circuit
Inventor: NESTLER JOHANNES DR ING
IPC: H02M1/08
Filed: 1979-07-28
Abstract: Galvanic isolation is provided between control signals and the load circuit without the need to supply trigger power from a separate source. The circuit comprises a series combination of diode and Zener diode (D1,D2) between the gate of the gate turn off thyristor (T1) and its cathode. In parallel with these diodes are the turn-off circuit (T2,R1,C1) and the turn-on circuit (T3,L,C1). A commutating thyristor (T4) is in parallel with the main thyristor (T1), and in series with the capacitor (C1). The triggering energy is provided by the capacitor (C1), whose polarity reverses after each switching oeration. It also acts, in conjunction with the fast acting commutating thyristor, to suppress voltages across the main thyristor when the latter is turning off. The gate signal for the auxiliary thyristors (T2,T3,T4) is typically provided through an optical transmission to give the required isolation.

Title: Insulated handles for pliers, screwdrivers etc. - are formed from thick moulded covering of foam plastics filling holes in metal core
Inventor: WIRTZ PETER
IPC: B25G1/12
Filed: 1979-09-05
Abstract: Hand tools such as pliers, screwdrivers etc. have handles (3) covered with a thick layer of polyurethane foam (4). The foam is moulded onto each handle which has several transverse holes which are filled with foam. The foam is sufficiently elastic to deform under the pressure of the user's grip and so provides a much firmer hold. The thickness of the foam renders it less susceptible to damage than is the case with tool handles covered with relatively thin layers of plastics and thus provides a more reliable electrical insulation.
