Title: Rotary iron drive control - with triac and comparator in motor supply for better reaction torque during pressing operation
Inventor: HEYER GUENTER
IPC: B30B3/00
Filed: 1973-08-16
Abstract: The electric drive of a rotary iron uses a single-phase induction motor with a main winding, an auxiliary winding and a capacitor acting through a friction brake; the moment of reaction of this brake is used to press the ironing mould against the stationary ironing roller when switched over from the ironing to the pressing posn. A triac in the feed to the motor adjusts the motor supply voltage under the control of a controller (2) with an input of the desired value of the voltage which corresponds to the max. motor torque, and with an input of the actually measured motor voltage. Device ensures, under all working conditions, a unifrom and larger press force of the ironing mould. the stalling torque of the motor can be shifted to coincode with the starting torque. The motor operates with a max. torque just below the braking torque of the friction brake even when the mains voltage drops.

Title: Shower bath head for intermittent spray - has perforated control disc driven by wheel with series of curved vanes to cover or release stream openings
Inventor: KOCH ULF
IPC: B05B1/18
Filed: 1973-08-23
Abstract: Shower bath head for hand showers and stationary showers produces intermittent spray streams, and the interruption or change of the streams is effected mechanically by a vane wheel which is rotated by the stream of water. Pref. the wheel drives a cover disc rotatably mounted on a bottom plate of the spray head and covering, or releasing via perforations, stream openings in the floor. The disc is connected to the wheel via a shaft which is guided, with conical ends, for easy rotation in the floor, a distributor pot or a hand shower housing. The design is simple and practical. The bearings of the wheel do not require special lubrication and the wheel is not prone to jamming. The turning moment on the wheel is produced by the flow of water past curved vanes.

Title: Specimen casing for electron microscope adjustable table - has surrounding conductive cage for electron back-scatter measuring
Inventor: NIEDRIG HEINZ PROF DR-ING
IPC: H01J37/244
Filed: 1973-08-30
Abstract: The specimen casing is insertable in the specimen table and is surrounded by an insulatingly mounted, electrically conductive cage for measuring the electron back-scatter at the specimen. Through the cage wall protrudes a component, conductively connected with the same, which is driven by an external drive so that in one end position it bounds the cage part facing the electron source against the specimen, thus preventing the electron passage to the specimen. In its other end position it permits the electron flow. The component part may be formed by a slider displaceable transversely to the casing axis. The slider may be guided in the specimen casing to enable a common movement of the cage and the slider in the direction of the casing axis.
