Title: A device for sprinkling pulverulent substances onto a fibrous fleece
Inventor: GEORGI KURT
IPC: B05D1/30
Filed: 1956-12-05
Abstract: 841,762. Agglutinated fibrous sheet materials; laminates. ZENTRALE ENTWICKLUNG UND KONSTRUKTION FUR DEN KRAFTFAHRZEUGBAU VEB. Dec. 5, 1956, No. 37240/56. Class 140. Resin powder 9 to be sprinkled on a moving fibrous fleece, e.g. a carded web being wound up on a rotating drum 18, is formed into a layer of non- uniform or, as shown, uniform depth resting on a conveyer belt 2 having its upper flight supported by a fixed plate 15, and is fed at a slow rate towards a rotating distributing roller or brush 8 by a transverse strip 12 secured to the conveyer belt, fixed walls 5 being provided at each side of the conveyer to retain the powder, which falls as a curtain 10 on to the fleece. A further rotating brush or scraper roller 11 serves to clean the roller 8. The walls 5 may be connected by transverse members 6 and 7 to form a frame resting on top of the conveyer belt and a layer or strip of felt 16 may be fixed to the lower edges of the frame to form a seal and reduce friction. At the reversal point where the powder is thrown off the belt, the belt passes over a small diameter roller or an angle bar 3 having a rounded front edge. The conveyer belt or the drum 18 may be automatically stopped when the resin supply is consumed. If the layer 9 is thicker at its two ends, the fleece wound on roller 18 has a greater resin content at its two surfaces, so that the finished moulding produced by hot-pressing the fleece has a dense, water-repellent surface.

As shown in Fig. 1 a mechanical tuning control is ganged to AM tuning inductors and to a variable inductor 1. When the radio is switched to operate in the FM band the variable A.C. output voltage from the inductive voltage divider 1, 2 is rectified and filtered at 8, 29, 30, Fig. 2, and is used as a tuning voltage for voltage variable capacitors 9 in the FM tuning circuit of the radio. The inductive voltage divider 1, 2 may form part of the tuned circuit of an oscillator 3 such as a Colpitts oscillator 12. The amplitude of the oscillations produced by the oscillator 3, 12 across the inductors 1, 2 is stabilized against supply voltage and temperature variations by a negative feedback circuit 4, 5 including a rectifier 19 and a D.C. amplifier 24, 26 having a reference voltage provided by a Zener diode 25. A transistor 23 provides the temperature compensation. The single variable inductor could be in the form of a bank of pushbutton selected inductors.

IPC: H02P23/00
Filed: 1957-12-06
Abstract: 889,988. Regulating. BLACKSTONE & CO. Ltd. Dec. 2, 1958 [Dec. 6, 1957], No. 38097/57. Class 7(6). A rapid or transient change in the load on a generator 1 driven by an internal combustion engine controlled by a governor 17 causes operation of a device which increases or decreases the fuel supply to anticipate the action of the governor. A transformer 3 associated with the output of an A.C. generator 1 is connected through a rectifier 5 to the primary of a transformer 7 the secondary of which is connected to a relay 8 which when operated energizes either coil 12 or coil 13 to increase or decrease the fuel supply respectively. An increase in load on the generator, detected by the -transformer 3, produces a transient current in the secondary of the transformer 7 to operate the relay 9 for a short period, moving the fuel control linkage 15 to increase the fuel supply in anticipation of the governor, connected to the linkage 15 through a -spring 18, operating to correct an incipient change of speed. The rectifier 5 and relay 9 may be replaced by thermionic valve or transistor devices. In a D.C. generator set the transformer 3 is replaced by a shunt from the generator output and the rectifier 5 is omitted.

Title: Improvements in or relating to Directional Aerial Systems and installations for use in Aircraft Landing Assistance
IPC: H01Q25/02
Filed: 1966-08-31
Abstract: 1,155,434. Aerials; radio navigation. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 31 Aug., 1966 [31 Aug., 1965], No. 38930/66. Headings H4A and H4D. An I.L.S. glide-path aerial system comprises an array made up of radiating elements 11, 12, Fig. 1, mounted on a mast 1 which is inclined away from the vertical by an angle equal to the required angle of descent. The number of elements 11 (as shown, twenty one) is greater than the number of elements 12 (as shown, fourteen) and the two groups are interleaved, with each symmetrically disposed about the centre 0 of the array, the spacing between adjacent elements 11, 11 or 12, 12 being one wavelength at the mean operating frequency. The elements 11 are so fed as to produce a lobe of radiation normal to the array, that is, directed along the glide-path, whilst the elements 12 are so fed as to produce a lobe of radiation directed upwardly from the glide-path, but arranged to have the same intensity along the glide-path as the other lobe. The radiating elements may be horizontal dipoles and a plane or curved reflector 13 may be provided behind them. As described, carrier power is fed from a terminal P, Fig. 2 of a transmitter 20 to a terminal 211 of a bridge 21 having three arms a, b, c, each a quarter-wavelength long and one arm d three quarter-wavelengths long, whilst side-band power is fed from a terminal BL of the transmitter to a terminal 212 of the bridge. The elements 11 are supplied with carrier and sideband power from a terminal 213 of the bridge, via a power control system 215 and power dividers 216, 217, 218, 219. The distribution of amplitude over the elements 11 is symmetrical about the centre 0 of the array, but may not be uniform. The elements 12 are supplied with carrier power in phase with that to the elements 11 and with side-band power in anti-phase with that to the elements 11, from a terminal 214 of the bridge. A power divider 220 feeds a sub-group 121 of the elements 12 which are above the centre 0, through an adjustable phase shifter 221 and a power divider 223, and it feeds a sub-group 122 of the elements 12 which are below the centre 0, through an adjustable phase shifter 222 and a power divider 224. The phase shifters 221, 222 give phase shifts of equal magnitudes but of opposite signs, so enabling the direction of the radiation lobe from the elements 12 to be adjusted in a vertical plane (Fig. 3, not shown). Operation of the power control system 215 enables the magnitude of the radiation lobe from the elements 11 to be adjusted, and hence it may be arranged for the intensities of the side-band energies in the two radiation lobes to cancel out along the glide-path direction (Fig. 4, not shown).
