Filed: 1949-10-25
Abstract: 669,151. Screens for vehicle radiators. COENEN, W. F. Oct. 25, 1949, No. 27411/49. Class 64(iii) A roller blind 4 operated by a cable 6 for screening a car radiator 2 is mounted in a frame 1 provided with rubber cushions 13 extending forwardly of the frame when, as in one method of use, (Figs. 1, 2, not shown), it is secured in position at the bottom of the radiator. Furthermore, if the frame is detached from the aforementioned mounting position, turned through 180 degrees in a horizontal plane or about the horizontal axis of the roller 3, i.e. to the disposition shown, and the free end of the blind attached to the bottom of the radiator, the rubber cushions 13 act as buffers between the frame and radiator when the blind 4 is exposed by raising the frame 1 and roller. The operating cable 6, whether attached to the blind 4 or frame 1 for the particular mode of use of the screen, passes through a tube 7 soldered to the radiator top and is attached to a chain 11 manipulated by the driver.

Abstract: 809,193. Electron microscopes. VEB VAKUTRONIK. Sept. 27, 1955 [May 10, 1955], No. 27429/55. Class 39(1). In an electron microscope of high resolving power, (a) the tips of the pole-pieces of a magnetic objective lens are operated at magnetic saturation ; (b) pole-pieces are used which have been produced by a process in which cavity-free iron is freed from internal mechanical stresses by means of thermal after-treatment while the axis of symmetry of each pole-piece has been maintained throughout aligned with the magnetizing magnetic field, and (c) the lens includes an apertured diaphragm heated temporarily or continuously, e.g. to 600-1000‹C., to destroy or convert insulating films into conducting layers of carbon, and so avoid polarization charges. The thermal after-treatment consists in heating the iron to a certain temperature, above 906‹C. for pure iron and above 720‹C. for iron with a carbon content of 0À9 per cent., and then cooling it as slowly as possible. Well forged or beaten iron is used. The lens diaphragm is preferably of platinum.

Abstract: 1,151,081. Investigating by measuring thermal emission. AUTOMATION INDUSTRIES Inc. June 21, 1966 [July 28, 1965], No.27717/66. Heading G1A. [Also in Division H4] A workpiece is inspected for flaws by heating an extended area and scanning it point-by-point with an infrared detector to locate hot or cold spots caused by voids, inclusions, delaminations &c. The workpiece 12, Fig.1 is flooded by radiation from a heater 14 and successive points on the surface are focused on a radio-meter 20 by a lens 30 and a mirror 28 mounted for rotation in two co-ordinates. The output of a radio-meter 20 controls the brightness of a cathode ray tube spot 46 scanned in syncronism with the mirror 28 to produce a thermal map of the workpiece. A switch 52 is provided whereby the heater may irradiate the workpiece at the same time as scanning takes place or alternatively the heater may be switched off before scanning commences so that the temperature distribution may be determined while the workpiece is cooling. In an embodiment for examining a rolled steel strip Fig. 2 (not shown) the field of view of the radiometer is scanned transverse to the movement of the strip. The heater radiates microwave, near-infrared or visible radiation and the radiometer detects for infrared (2-15Á).

Title: Improvements in or relating to a device for applying glue coatings of varying thickness to surfaces
Inventor: OFFENEY SIEGFRIED
IPC: B05C1/08
Filed: 1964-07-07
Abstract: 1,001,037. Coating apparatus. LEIPZlGER BUCHBINDEREIMASCHINENWERKE VEB. July 7, 1964, No. 27982/64. Heading B2B. A device for applying glue coatings of varying thickness to surfaces fed into the device, comprises a plurality of rollers one of which is a pick-up roller 2 partially immersed in a glue tank 1 and transferring the glue directly or by further roller or rollers to a coating applying roller 4, feeler means 6 arranged in front of the applying roller in the direction of surface feed, at a distance depending on the circumference of the coating roller and adapted to be actuated by the surface to be coated before the commencement of the glue application, and adjustable control means arranged between the pick-up roller and the applying roller, or co-operating with the pickup roller or the applying roller and actuated directly or indirectly by the feeler means so as to cause variation in the thickness of the layer of glue on the applying roller between two predetermined limits. The embodiment shown is used for gluing a book filler 14 and consists of two gluing devices one on either side of the path of the filler 14. The feeler means consists of a roller 6 adjustable in support means 7 which also carries the applying roller 4. The support 7 is slidably mounted and is urged towards the path of filler 14 by spring 11 within the limit of an adjustable stop 8, 9. Movement of support 7 is also limited in the opposite direction by an adjustable screen 13. In the first position of the support a relative thick layer of glue is formed on the roller 4 and in the second position a much thinner layer of glue is formed on the roller 4. The arrangement is such that as the book filler 14 approaches the feeler roller 6 there is a relative thick layer of coating on roller 4, when the filler 14 contacts the roller 6 the support 7 and roller 4 are moved towards roller 2 so causing the layer of glue on roller 4 to be thinned so that when the filler 14 contacts roller 4 first a relatively thick layer of glue is deposited thereon followed by a thinner layer. By adjusting the position of roller 6 in relation to the circumference of roller 4 the width of the thick layer can be varied. The feeler means may alternatively be in the form of electrical contacts, mechanical feelers &c. for operating ancillary power sources for varying the quantity of glue applied.

Title: Improvements relating to coded track circuits for railways

Abstract: 689,457. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., STEVENS. S. A., and WALKER, A. H. B. Aug. 4, 1950. [Nov. 3, 1949] No. 28181/49. Class 105. The alternating current of a track circuit is coded by being modulated by a static coder in the form of a low frequency oscillator the frequency of which is determined by the traffic conditions. Magnetic oscillators and amplifiers as described in Specifications 521,719, [Group XL], 521,798, [Group XXXIX] and 535,861, [Group XXXV], are preferably used, the magnetic oscillator being of the magnetic amplifier type. Alternating current the voltage of which is kept constant by a stabilizer 5 is fed to the exit end of a track circuit AT through the usual limiting impedance 4 which is however saturable by a winding 7 fed from a magnetic oscillator 8 which is supplied with the stabilized alternating current and which gives a current of frequency f<SP>1</SP> or f<SP>2</SP> as determined by the traffic conditions opening or closing a contact 10 to exclude or include a condenser 9 thereby tuning the oscillator to one or other frequency f<SP>1</SP> or f<SP>2</SP>. The track circuit current is thus an alternating current modulated at frequency f<SP>1</SP> or f<SP>2</SP> . At the entrance end of the section AT this current operates a transformer 11 tuned to the alternating current (carrier frequency). The transformer secondary feeds through a full-wave rectifier 12 the control winding of a magnetic amplifier 13 supplied with stabilized alternating current. The output of the amplifier thus modulated at frequency f<SP>1</SP> or f<SP>2</SP> is applied to a demodulator or rectifier 16 to give a current of frequency f <SP>1</SP> or f<SP>2</SP> which actuates a tuned circuit 17 or 18 including transformer, rectifier, and control winding of a magnetic amplifier 23 or 24 to light an appropriate clear or caution lamp 26 or 27 of the entrance signal 29 for section AT. The danger signal 28 is controlled by its magnetic amplifier 25 being biased in such manner that so long as current of frequency f<SP>1</SP> or f<SP>2</SP> is present and is applied through a blocking condenser 19 to the transformer 30 to feed the control winding of the amplifier 25 the bias is counteracted and the lamp 28 is not lit. When however, an entering train shunts the track section AT no track circuit current reaches the transformer 11 and so the amplifier 13 is unoperated and no demodulated current of frequency f<SP>1</SP> or f<SP>2</SP> arises ; accordingly the lamps 26, 27 are dark but the danger lamp 28 of the entrance signal 29 now becomes lit due to the bias on the control winding of the magnetic amplifier 25 no longer being counteracted. The modulated track circuit current may actuate train-carried apparatus to give signals thereon.
