Title: Ceramic varistor prodn. from zinc oxide mixt. - contg. praseodymium, cobalt and calcium, for protecting low voltage electronic equipment
Inventor: NAGASAWA IKUO DIPL ING
IPC: C04B35/453
Filed: 1976-06-16

Title: Three phase pole-changing motor - changes from delta to double star configuration with soft run=up by delaying connection of star point
Inventor: REICHERT GERHARD
IPC: H02P25/20
Filed: 1976-11-05
Abstract: In pole changing motors using a change from delta to double star connection between low speed and high speed the starting current in the high speed condition can be very high. This current is reduced by introducing a time delay between the closing of the paralleled windings ends (1-6) onto the supply (8, R, S, T) and closing the star point forming contactor (9). With the star point open the motor starts with reduced torque in a quasidelta connection but with the correct pole number. At the selected time interval the solid star point is made and the motor is available for full output.

Title: Retention arrangement for domestic washing machine housing - has two part hook strip between rear wall and housing frame part
Inventor: HUBER HEINRICH
IPC: D06F39/14
Filed: 1977-02-03
Abstract: The retention arrangement is for the housing (1) of a domestic appliance eg a washing machine, with a removable rear wall (2) and cleaning flap door (3). Between the rear wall and the frame part of the housing is a two part hook strip, one part being on the rear wall inner side, and the other on the facing outer side of the frame part. By pressing the strips together retention is achieved, and to release, the rear wall is removed, separating its strip from the other. A smooth walled connection can be achieved by having a recess in the frame part to hold the hook strip. A similar retention can be used between the flap door and the housing.

Title: Lock=in and coupling arrangement for kneading machine - having system to rigidly hold mixing bowl when mixer element is lowered
IPC: B01F7/16
Filed: 1977-03-30
Abstract: Lock-in and coupling system for a kneading and mixing machine has movable bowl with rigid housing to which it is fixed. Also it has a mixing element. Whe the bowl is pushed against the machine this is detected by a limit switch. The bowl is then coupled onto the machine by the lock device in a first loose engagement. The signal so generated serves to move the mixing element into a first inward movement stage, controlled by a timer relay. By means of a subsequent manually initiated stage the element takes up a second working position. This initiates a tilting motion in a friction coupling wheel on the bowl mounting, clasping it tightly to the housing. This then acts as a lock in without play between the bowl and the housing. For use with dough kneading plant in the baking industry. The lock-in device requires no special drive connection andis integrated within the drive mechanism of the machine.

Title: Automatically operated flap for flue gas channel - has pivoting shaft ensuring unstable equilibrium in any flap open position
Inventor: STEIMER ALOIS
IPC: F23L11/00
Filed: 1977-05-07
Abstract: The automatically operated closing arrangement is used for flue gas channels, especially in heating plants. A swivel flap is opened before firing starts and it is closed after furnace is shut down. This prevents the danger of thermal overloading of boiler parts by radiant heat after shutting down the burner. The flap (2) is made of lightweight material such as sheet metal. The axis of rotation of the flat shaft (3) is in the plane (d) parallel to the channel mid plane (x) so that the flap (2) is in unstable equilibrium in any opening position. The axis of rotation of the shaft is a distance from the flap (2) so that the flap is approximately in the mid plane (x) of the flue gas channel when the flap is fully opened.

Title: Pure methyl-di:chloro-phosphine prepn. - by two stage distillation to remove phosphorus tri:chloride, carbon tetra:chloride and chloroform
Inventor: GEHRMANN KLAUS DIPL CHEM DR
IPC: C07F9/52
Filed: 1977-05-28
Abstract: Pure methyldichlorophosphine (MDCP) is sepd. from a mixt. of MDCP, PCl3, CCl4 and CHCl3 by (a) removing PCl3 and other low b.pt. fractions in a first-stage distn. (temp. at bottom of column is not >115 degrees C, not >105 degrees C) and (b) sepg. the MDCP from high b.pt. fractions in a second-stage distn. (temp. is not >120 degrees C, 102-110 degrees C). Before the first stage, 0.01-1% of an org. Ba cpd. (esp. mixt. of Ba sulphonate and Ba phenolate) or 0.1-10% (0.5-5%) of a non-ionic surfactant (esp. an ethoxylated 6-30C unbranched fatty alcohol, e.g. ethyleneoxide polymer) is dissolved in the mixt. Before the second stage, 1-10% (3-6%) of POCl3 is added to the fraction from the base of the first distn. column. MDCP is used as a starting material for the flame-resisting of fibres and plastics. It must be very pure if it is not to adversely affect the materials, e.g. by discoloring them. Usual method of prepn. of MDCP gives high % of impurities of similar b.pt. (viz. CCl4, PCl3). It is very difficult to separate them by distn. The present method overcomes these problems.
