Title: Improvements in or relating to wireless signalling systems
IPC: G01S1/02
Filed: 1928-09-26
Abstract: 327,112. Robinson, J. Sept. 26, 1928. Directive signalling.-In a direction-finding svstem in order to minimize the effect of interference in blurring the critical indication, the required bearing is transmitted as a visual effect in the form of a scale of degrees, with or without the name of the transmitting station and an indicating pointer, by still-picture or television apparatus of known type, and a directional effect is superposed either by using. a rotating frame or other directional aerial, at the transmitting or receiving end, whereby the required bearing is visibly indicated by the suppression of a definitely orientated part of the received picture. As shown in Fig. 1, still-picture transmission apparatus 10, 12 is used to send a facsimile of a scale of degrees 11. At the receiving end, owing to the effect of the rotating-loop transmitting aerial 14, the scale 18 is shown with blank portions corresponding to the bearing of the aerial 16 relatively to the transmitter. In Fig. 2 television apparatus 26, 27, 28, of known type, is used to transmit the image of a pointer 25 rotating at a constant speed. An aerial 31 -also transmits a non-directional orientating signal at definite intervals, i.e. when contacts 33 are short-circuited by brushes 34 on the rotating pointer. At the receiving station 36, a moving image of the pointer 25 is shown on the screen 40, which may be graduated as a compass card, but the image vanishes along a definite diameter corresponding to the required bearing. Alternatively non-directional aerials may be used to give a continuous moving picture, the orientation of the pointer at the moment when the signal from the aerial 31 is received then indicating the bearing. Or the picture of the pointer may appear on the screen only along that diameter which corresponds to the true bearing. The effect of interfering signals will mar the general symmetry of the picture and is therefore readily distinguishable from the desired " bearing " indication.

Abstract: 406,784. Polishing razor blades. BASSAT, H., Ohligs, Solingen, Germany. Oct. 5, 1932, No. 27662. [Class 60.] Cutting edges, shaping and treating; guides and rests.-A machine for polishing safety razor blades comprises an endless belt conveyer on which the blades are mounted, and a number of pairs of polishing discs, rollers or the like, disposed alternately below and above the conveyer and having their axes parallel to but offset from the longitudinal axis of the conveyer in such manner that the sides of the edges of the blades are polished alternately. A table 2 is provided with brackets 5 supporting a pair of polishing rollers or like 6 and an upper table 7 similarly carries a second pair of polishing rollers 8. An endless conveyer band '13 passes over pulleys 11, 12, and the blades x to be polished are placed over studs 14 carried by the conveyer. The polishers are adjustably mounted in relation to the conveyer. The first pair 6 of the polishing rollers are positioned beneath the blades carried by the upper run of the conveyer so as to polish the under side of the blades while the second pair of polishing rollers polishes the upper side of the blades. If desired the upper polishing rollers may be arranged in front of the lower rollers. The polishing rollers are driven by belt gearing 19 and are offset from the central plane of the conveyer so that the two rollers of a pair act on opposite cutting edges. Lateral deflection of the blades during polishing is prevented by bars 24, Fig. 11, mounted on guide rails 16. Bars 25 form steadying abutments for the blades during polishing and tilting of the blades is prevented by wires 26. The bars 27 which prevent lateral deflection of the blades may have interfitting teeth which form a bevelled slot 27b, Fig. 8, which is alternately interrupted at the top and bottom. Or the blade guide may consist of spaced members separated by a thin metal plate to form a slot into which the blade projects. In another modification, the blade supporting guides may be replaced by parallel inter-engaging rollers 27, Fig. 13, or by pairs of conical rollers arranged on vertical axes. Two, four or more pairs of polishing rollers may be employed the successive pairs acting alternately on the top and bottom of the blades. After the completion of the polishing operation, the blades are preferably returned on the conveyer by means of a casing 31 extending around the wheel 12 to a point 32 adjacent the operator where the blades fall from the conveyer into a suitable receptacle. The polishing tools may have suitable jackets for the circulation of water or other cooling medium. Specification 406,783 is referred to.

Abstract: 847,392. Electric tests. SQUARE D CO. Sept. 3, 1957 [Sept. 13, 1956], No. 27743/57. Class 37 Metallic objects are detected by a magnetic transducer comprising a first inductance inducing two opposing voltages in a second inductance which differ by asmall phase angle.Presence of the metallic object alters the phase of this output signal substantially and the phase change is used to effect a control. As shown, Fig. 2, the first inductance comprises coils 21,22supplied in series from these condary of transformer 27 and wound on a common laminated core with the output coil 23. Initially the outputs are made equal by means of potentiometers 24, 25 shunting the coils, and a tuning slug 26 at one end of the core. The voltages induced in the secondary are -E x  and E s  (Fig. 10) differing by a small angle #, Presence of metallic material changes the length of E x  to cause substantial volation of the output voltage E r  from the secondary coil. The output voltage is coupled by a harmonic filter capacitor 32 and phase adjusting circuit 33, 34 to a two stage resistance capacity amplifier 36 controlling an A.C. feed thyratron 40 the grid of which is provided with a D.C. bias from battery 44. Adjustable resistor 43 points a sensitivity control by adjusting the phase of the signal voltage. A further sensitivity control may be provided when the size of the object is unimportant by varying the D.C. bias. In the anode circuit of the thyratron is a relay 50 controlling a load 55 and provided with a C.R. circuit 52, 53 control the delay time. In the arrangement of Fig. 3 (not shown) the thyratron is provided with an A.C. bias while the driving coils are in series and shunted by a single potentiometer adjustment of which controls their relative contributions to the field in the output coils. In a still further arrangement (Fig. 4, not shown) a transistor amplifier is provided for the output and the shield of the thyratron is fed with a half-wave alternating voltage which prevents false triggering of the thyratron during the positive swing of the plate supply voltage. Fig. 6 shows a construction of transducer where 131, 132 are the driving coils and 133 the output coil. A central laminated core is provided and is attached to threaded rod 41 which permits of longitudinal adjustment of the core. Nut 147 presses a fibre end plate 142 against the end of the core. The whole assembly is provided with a steel jacket 136 except for one end where the object to be diluted passes and this is covered by a fibre end cap 137.
