Title: Double entry air conditioning centrifugal fan - has housing scroll with central partition to form two fans with separate outlets
Inventor: BINIEK HORST
IPC: F04D25/16
Filed: 1977-04-20
Abstract: The centrifugal fan is particularly intended for combined air supply and extract and comprises a stationary motor stator with external rotor ring (4). This carries impeller blades (6) to form a double-entry centrifugal impeller and a spiral housing scroll (10). Approximately mid-way of the blade width, a partition (9) is provided which divides the housing into two separate sections (10, 10a). The two sections may be symmetrical relative to the partitions. The two housing scrolls may have their outlets diametrically opposed to give flow in opposite directions. The partitions may be a common wall of the two housing scrolls. The blades may be split (5, 5a) half-way their width.

Title: Stepper motor control with chopper type regulator - operates with pulse width and frequency defined by programme stored in microprocessor
Inventor: HERMANN MICHAEL DIPL PHYS
IPC: H02P8/34
Filed: 1977-05-13
Abstract: In order to drive the motor in a particular manner, for example with a specific torque/time relationship, the chopper control frequency and pulse width are under the control of a preset programme. This programme ensures that the mean value of the winding current follows the prescribed stable function. The mean value can be made to follow a sine function.

Title: Monitoring device for wired TV systems - has each monitoring unit controlled by clock signals transmitted on second frequency
Inventor: SCHUMANN ALFRED
IPC: H04B17/40
Filed: 1977-06-03
Abstract: A monitoring unit is allocated to each system which requires monitoring. It is able to produce signals giving a measure of the state of the monitored unit, as in 2522441. Each monitoring unit is controlled during a test period of an interrogation signal by a number of clock signals transmitted on the second frequency. The system may be used in TV networks where the signals are transmitted along wires. The second frequency is modulated by the clock signals and may be demodulated to obtain the picture synchronisation signals.

Title: Coloured, embossed, imitation suede esp. chamois leather - made from nap cloth e.g. cotton velveteen impregnated with a tinted polyurethane soln. which is then pptd. and hot embossed
Inventor: KERRES BRUNO DIPL CHEM DR
IPC: D06N3/00
Filed: 1977-08-30
Abstract: In parent patent, mfr. of imitation suede, esp. imitation chamois leather, comprises impregnating a nap fabric with the nap on 1 or both sides, with a soln. of a synthetic elastomer in an organic solvent e.g. a polyester or polyether urethane in DMF; precipitating the resin by wet-coagulation to bond it to the nap fabric; and subjecting the surface, after drying, to a finishing treatment. In this addn., before the soln. is applied to the fabric it is coloured to a pale or medium hue. The dried fabric is hot-embossed. The combination of suitably coloured soln. with the final embossing step where appropriate embossing patterns are applied gives a prod. which has an appearance almost indistinguishable from natural suede or chamois leather.

Title: Piezoelectric lighter with sheet metal housing - having opening accommodating element and sliding cylindrical hammer with blind hole at one end for spring
Inventor: HAYASHI TOSHIO
IPC: F23Q3/00
Filed: 1978-12-09
Abstract: The piezo-electric lighter has an actuating rod slid by hand in the lengthwise direction in opposition to a first spring. This causes a hammer to compress a second spring, and further movement trips the hammer free from a lever, so that it strikes the piezo-electric element to generate the spark. The housing consists of a sheet-metal stamping forming a support plate with a rectangular central portion and walls bent over at its narrow sides. An oblong opening is stamped out of the central portion, together with one or more lugs bent upwards. The trip lever rocks in a plane parallel to the central portion, and in the rest position is thrust by a spring against the rod.

Title: Twin range pneumatic timer - has metering disc with two air channels connected to inlet chamber by bores of fixed and adjustable ring
Inventor: AMMANN ECKHARD ING GRAD
IPC: H01H7/02
Filed: 1979-04-19
Abstract: Two times ranges selected by a lever improve the function of the pneumatic timer featuring a metering disc with two concentric air channels. The first channel of the metering disc opens into its bore while the other channel terminates in an air inlet chamber. The short time range is achieved by connecting the first channel through aligned holes of the setting ring and switching ring. The longer time interval is secured by shifting the switching ring w.r.t. The setting ring and thus closing the connecting bores.
