IPC: H02P23/22
Filed: 1976-09-27
Abstract: Digital controller with proportional and integral action includes a comparator forms a mean value of the control difference by comparing a command variable frequency and sign with a control variable frequency and sign in a clock period. A proportional element stores a numerical value defining the proportional action and is connected to a first limiting stage.

Title: All purpose brush with porous handle - has bristles secured to intermediate underlay and can be used either dry or wet
Inventor: ANTHON BORWIN F
IPC: A46B5/00
Filed: 1976-10-01
Abstract: An all purpose brush has an extremely light handle (1), with an under layer (2) in which sterilised bristles (3) of natural or synthetic material are firmly embedded. The bristles can be made from well proven fibres used for carpets with a relatively long life. The handle is made from a material which is lighter than water and is also absorbent so that it creates a lather when used with soap.

Title: Ventilation system for driver's cabin working in dusty atmosphere - has re-circulating pipe to reduce vol. of air through filters
Inventor: NELKEN EWALD
IPC: B08B17/00
Filed: 1976-10-27
Abstract: The drivers cabin (2) of a road vehicle or a crane operating in a dusty or harmful atmosphere is supplied with air by a fan (5) to maintain the pressure in the cabin slightly above that of the atmosphere. The air is drawn through the inlet pipe (3) and the filter (4) and delivered to the cabin (2) through the pipe (6). In order to reduce the duty of the filter a recirculating pipe (10) connects the cabin (2) with the down-stream side of the filter. The cross-sectional area of the pipe (10) is one-third of that of the delivery pipe (6). When the required over-pressure is reached in the cabin (2) the air in the cabin is re-circulated through the pipe (10). As the filter (4) is thus not operating continuously the time between filter changes is considerably increased.

Title: Monitoring and level control device for HV line carrier system - uses three pilot frequencies for criteria transmission, and if pilot is missing gives alarm
Inventor: MOELICH HORST ING GRAD
IPC: H04B3/46
Filed: 1977-07-06
Abstract: The carrier system is used for signal transmission over h.v. power lines and uses a pilot circuit in the transmission and reception directions. Two pilot frequencies are used for derivation of a level control criterion for the receiver i.f. amplifier, and for transmission of a dialling or engaged criterion. When a pilot is missing, a local alarm is given. Pilot frequencies are generated by coherent frequency shifting. At least one further pilot frequency is used for transmission to the opposite station of further criteria for operational states. When these criteria are received, or a pilot is missing, certain functions are carried out.

Title: Improving breakdown resistance of polyethylene insulated HT cables - through interlinking and cooling by selected media
Inventor: KURZ RAINER
IPC: B29C48/885
Filed: 1977-07-19
Abstract: To improve its resistance to breakdown, the insulation of a HT cable consisting of polyethylene which is extruded on to the conductor, is subjected to further treatment. Immediately after extrusion the insulation is treated with a medium which consists, at least partly, of a substance which effects a diffusion of the medium into the still plastic insulation from the extruder, and thus raises its resistance to breakdown. Pref. the polyethylene is reacted to set up interlinking after extrusion, and then cooled. A medium free from water is selected, which, besides raising the resistance of the insulation to breakdown, also brings about the interlinking when heat is applied, and the insulation is then cooled by it. The temp. range is 180-280 degrees C and pressure 2-26 atmos.

Title: Single phase capacitor motor with speed changing facility - has series resistor for low speed starting in parallel with PTC resistor
Inventor: MEYER SIEGFRIED
IPC: H02P1/44
Filed: 1978-05-02
Abstract: The single phase capacitor motor with a speed change facility can be used for water pump drives in heating installations. The low speed setting is selected by inserting a resistor in series (13) with the supply. To ensure certain starting at low speed a resistor with positive temp. coefficient (14) is connected in parallel with the speed change resistor. The cold value of the PTC resistor is lower than the series resistor (13) whilst the hot value is greater by a similar factor. Thus, at starting a current approx. equal to the high speed starting current flows giving a corresp. starting torque.

Title: Pile fabric napping - uses the same roller to teasel the pile surface twice
Inventor: SISTIG ALFONS
IPC: D06C11/00
Filed: 1978-06-12
Abstract: In raising the pile of a fabric, the material is teaseled twice after it has been beaten and heated. Teaselling the pile twice opens and fixes it at the same time, giving an even pile surface. The double teaselling action is effected by the same roller, by the fabric passing over two rotary angled surfaces with the fabric path being turned between the two phases. The fabric is presented to the teasel roller so that one side moves from the side at a tangent to the roller; it is then led down and upwards to bring it at a tangent to the roller from the other side before being led away. The reverside side of the fabric is beaten between the two teaselling phases.
