Abstract: 348,328. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. April 7, 1930, No. 11033. Convention date, April 16, 1929. [Class 40 (v).] Television, multiplex-telegraph and other signals of high frequency are transmitted by metre and decimetre waves which are radiated in a sharply concentrated beam and are modulated by one or more intermediate carrier frequencies which carry the signal. Several sets of signals may be transmitted independently on a corresponding number of intermediate carrier frequencies modulating the same high-frequency carrier wave. The modulated waves are transmitted from a di-pole aerial 7 at the focus of a concave mirror 8 and fed from an externally-controlled transmitter 1 which is modulated by an intermediate frequency carrying signals from a television scanning apparatus 2. The modulated waves are received by a di-pole aerial 9 at the focus of a mirror 10, demodulated by a valve 11, and passed through a demodulating amplifier 12 to a television receiver 13. The mirrors are so high above the earth that the path of the beam lies at a great height above the earth in comparison with the wave length. Signals are relayed along a line of stations by receivers and transmitters in cascade with intermediate amplification, Fig. 2 (not shown). The Specification as open to inspection under Sect. 91 (3) (a) comprises also the direct modulation of the high-frequency carrier wave by the signals. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for separating and feeding single labels, wrappers, or the like from a pile
IPC: B65C9/08
Filed: 1928-04-14
Abstract: 315,472. Rose, W., and Rose Bros. (Gainsborough), Ltd. April 14, 1928. Sheet - separators; pile supports. - In connection with a sheet-feeding apparatus of the kind in which the sheets are separated. from a pile in a magazine by means of an oscillating adhesive device 10, Fig. 1, which is moved radially to receive its adhesive from a reciprocating roller coacting with a roller 13, the sheets are advanced in the magazine by flexible plates 26 adapted to be engnged with and removed from holders 24 carried by conveyer chains 15, 16, Figs. 1 and 3, passing over sprockets 17 - - 20, the sprockets 18, 20 being secured to a sleeve 31 freely mounted on a shaft 32 and normally connected so as to rotate in unison by a sleeve 47 with teeth 50 engaging notches in the sleeve 31, and formed with clutch teeth engaging similar teeth in a fixed boss 46 on the shaft 32. The magazine is horizontal or inclined and the sheets rest on edge on the conveyer chains. The lower pulleys are adjustably mounted in slots 22 in a frame below the magazine. The magazine is formed of side members 28, and a bottom 27 formed with a slot 29 through which the plate holders 24 pass. The conveyer chains are advanced intermittently by mechanism controlled by an oscillating member 33 actuated by the labelling or other machine to which the sheets are fed, and the transmitting means includes a sleeve 35 which is oscillated on a shaft 36 and transmits motion via a spring 39 to a sleeve 41 formed with an arm 42 which oscillates an arm 43 on a sleeve 45 having a one-wav drive connection with the shaft 32. The spring 39 can yield if the chains tend to advance the pile too rapidly, or if the sleeve 47 is held fixed by means of a pawl 54 engaging a ratchet 49 on the sleeve. To adjust the chains by hand, the sleeve 47 can be pushed inwards against the action of a spring 51, thereby declutching the chain sprockets from shaft 32. The plates 26 are preferably supported by lips 30 which rest on the top edges of the magazine sides, and the plates 26 slope towards the front of the magazine. The labels or sheets are retained in the magazine by pins on the bottom of the front of the magazine, and on the pivoted sides 56, 57 and top 59. The side plates 56, 57 are controlled by springs 61 and are connected by rods 62, 63 and a ball-and-socket joint 64, 65.

Title: Amplitude-limiting signal-translating channel
IPC: H03G11/00
Filed: 1941-08-29
Abstract: 552,499. Wireless receiving circuits. HAZELTINE CORPORATION. Aug. 29, 1941, No. 11061. Convention date, May 28, 1940. [Class 40 (v)] A limiter, particularly for a frequency modulation receiver, includes a valve, between anode and cathode of which the signals to be limited are applied, wherein the screen grid potential determines the limiting amplitude of the positive half cycles by current saturation of the valve, and wherein cathode bias determines the amplitude of the negative half cycles by current cut-off. In Fig. 1 a limiter 15 is inserted between the intermediate frequency amplifier 14 and the frequency modulation detector 16 of a conventional frequencymodulation receiver and includes a valve 25 the cathode 26 of which is connected to one end of the secondary winding 22 of the intermediate frequency transformer a tapping a on which is earthed through condenser 24 and connected to a source -C of low negative potential. The anode 27 is connected to earth by a resistance 28 and inductance 29. The potential of the screen 30 determines the level of the positive half cycles by current saturation while the bias -C determines the amplitude of the negative half cycles by current cut-off. The arrangement is made such that the positive half waves are limited slightly less than the negative half waves since the anode current saturation increases slightly for large signals. This gives a signal across 28, 29 in which the negative half 'waves' are of' slightly greater amplitude than the positive half waves and this is connected to the valve. 35 by current cut-off to make both half waves equal. The lower end of secondary 22 is connected to the anode through a neutralising condenser 34 to neutralise any signal which has passed through valve 25 by inter-electrode capacity. In a modification, Fig. 4 (not shown), valve 35 is dispensed with, and valve 25 is operated so as to limit both halves of the wave equally. Specification 477,370 is referred to.

Title: Improvements relating to apparatus for and methods of carrying out reactions betweensolids and gases
IPC: C22B1/10
Filed: 1959-04-01
Abstract: <PICT:0861495/III/1> <PICT:0861495/III/2> <PICT:0861495/III/3> In reacting a finely-divided solid with a gas wherein a gaseous product is obtained, the solid is agitated in a rotary kiln (1) to which the gas is admitted under pressure and the gaseous product is withdrawn from a space (25) surrounding said kiln, said kiln having part or all of the wall constructed of a porous material, whereby the gaseous product is kept free from particles of the solid product.  The numerals relate to Fig. 1 in which the kiln has porous stainless steel walls and is rotated by means of water-cooled shaft 3 and surrounded by an impervious vessel 2 from which the gaseous product is withdrawn by line 16.  The reactant gas is introduced through pipe 9 surrounded by porous steel tube 10 having a non-return valve 12, said pipe and tube entering the kiln through a neck portion 11 which is supported in a corresponding portion 24 of the outer vessel.  The neck assembly is watercooled.  The porous walls may alternatively be ceramic, or metal-ceramic material, or of copper-nickel alloy, nickel-chromium-iron alloy or aluminium.  In Fig. 2, flow arrangements for the production of nickel carbonyl is shown: carbon monoxide is passed at 1-75 at., preferably 28 at., into a kiln containing nickel particles having a size below 100 microns from compressor 22 through valve 32 and passes out of the kiln through said valve to condenser 27 where the liquid carbonyl is condensed and from which cooled carbon monoxide may be recycled to the kiln by pump 29.  Part of the recycle stream may be passed as cooling fluid to the outer chamber by blower 30.  When the layer of nickel particles builds up on the inner wall of the kiln part of the carbon monoxide flow may be reversed by means of valve 32 and by-pass line 33 having a non-return valve 34 and orifice 35. Alternatively, the adhering layer 39 may be continuously stripped as shown in Fig. 3 by means of gas jets from a row of nozzles 38 directed against the outer wall of the kiln.  In an example, the nickel is first prepared in the apparatus by reduction of iron oxide with hydrogen and then cooled to 40 DEG  C. before introducing carbon monoxide.  Carbonyls of iron, cobalt, molybdenum, chromium and the precious metals may be similarly obtained and the starting material to be directly treated with carbon monoxide may comprise ores, concentrates or grinding dust in which the metal value is present to an extent as low as 1% and in combined form, e.g. as oxide.  The apparatus may also be used to roast metal sulphides, e.g. nickel sulphide, and to calcine carbonates.

Title: An automatic titrator
IPC: H01J17/00
Filed: 1960-03-31
Abstract: <PICT:0887576/III/1> In an automatic titrator comprising a motor-operated metering pump for liquid to be titrated, a titration vessel, a motor-operated metering burette, a detector, a programmer operating the pump and burette in dependence on a defined sequence and responsive to the detector signal, and means for indicating the amount of titration liquid employed at the end-point, said burette comprises two chambers connected by a diaphragm, one for the titration liquid and the other for an inert liquid such as an oil, the latter being connected to a piston cylinder whereby the titrating liquid can be drawn into and expelled from the first chamber.  In the illustrated apparatus, the burette is formed in two parts 24, 25 separated by flexible diaphragm 26 and having chambers 27, 28 respectively for an inert liquid such as an oil, and for the titrant. A duct 36 connects chamber 27 to a piston chamber 37, having a piston 38 attached to rod 39, operated by motor 42 through a worm gear 41; a bore 43 in the rod which is closable by device 44 serves to vent chamber 37 when necessary.  The titrant is supplied to the chamber 28 through channel 32, duct 29 and a bore in cock 31 by withdrawing the liquid from chamber 27, by raising the piston until the diaphragm is in contact with the left hand side of chamber 27, and discharged, after rotating cock 31, through said bore and duct and through channel 33.  The cock is rotated as required by means of motor 34, the contacts 35 being closed by a cam disc above the cock, whereby the motor is de-energized when the bore is in the appropriate position.  A further channel is provided in the right hand portion 24, to carry away liquid which is discharged around the cock, if the latter rises due to generation of excessive pressure.  The position of the piston may be determined conventionally, e.g. by means of a photo-cell or by the tele-transmitter system illustrated at 45-48. The result may also be obtained by drop-counting.  For metering the liquid to be titrated, a diaphragm pump (not shown) consisting of two portions each identical with the right hand part 24 of Fig. 2 is disclosed, each of which is connected to a pressure pump supplying the liquid to be titrated and discharges into the titration vessel, which is supplied with the requisite amount of liquid by passing liquid into one chamber until the diaphragm is pressed against the wall of the other chamber and then repeating this operation twice and collecting the two discharged volumes of liquid.

Title: Improvements in and relating to parachute containers
IPC: B64D17/52
Filed: 1955-04-21
Abstract: 768,526. Parachutes. ETUDES ET FABRICATIONS AERONAUTIQUES. April 21, 1955 [April 23, 1954], No. 11515/55. Class 4. A parachute container comprises a tubular sheath of flexible material 1 provided at each end with first loops 8, 9 adapted for gathering together these ends by cords 10, 11 breakable by a tension of several tens of kilograms, and secured to the sheath, second loops 13 of the same order of strength as the static line B which may be engaged therewith, and third loops 14 for securing the container to the load by cords 15 which together can withstand a tension less than that exerted by the load at the end of its free fall before deployment of the canopy, but greater than that withstandable by the cords 10, 11. In Fig. 1, the loops 8, 9, are formed on the end of tapes 4 stitched to the sheath, and loops 13, 14 on tapes 12 similarly secured. To pack the parachute, the loops 8 are drawn together by cord 10, the parachute being inserted in the open end with the crown adjacent loops 8. A strong loop C engages cord 10, and also a line D attached to halyards secured to the canopy crown, Fig. 4. The loops 14 are attached to the load by cords 15. The shroud lines are each folded and passed through an elastic loop 18, Fig. 1, on a band 17 stitched inside the sheath 1. The loops 9 are then drawn together by cord 11, which is also passed through a bight g forming the suspension point of the shroud lines G, Fig. 8. A strong strap H connects this bight to the load A. There are two modes of operation, the first as shown in Fig. 4, where the static line B is attached to the loop C only. When the static line B tautens, cord 10 is snapped, and the line D pulls the parachute crown first from the container, the suspension lines following. The sheath 1 remains attached to the load by cords 15. In the second mode, the static line B is also passed through the loops 13. When the line B tautens, the cord 10 is not snapped due to the strength of loops 13, but the cords 15 break. The load A starts to separate from the container, Fig. 8, pulling out the shroud lines. This snaps cord 11, permitting the canopy to follow the shroud lines. Cord D connecting the line B to the crown then snaps, and the container is left attached to the static line by loops 13. In a modified container, the loops 18, Fig. 1, are formed on an apron flap which lies inside the container and covers the aperture left when loops 8 are drawn together. Those loops may be replaced by loops of tape, or by pockets formed in the apron.

Abstract: 1,019,976. Photo-electric weighing control. HUNTING ENGINEERING Ltd. March 20,1964 [March 22, 1963], No. 11538/63. Heading G1A. In an automatic packet filling machine in which packets are fed past a succession of stations, the empty packets are weighed at a first station, a second being made of the weight of each, the packets are bulk-filled to about 95% at a second station, and at a final station they are topped up under the control of means which compares the recorded packet weight with the gross weight of the packet. If a packet is still found to be under weight it is rejected. The weigh-head at the first and final stations comprises a beam 11 which is provided with balance weights 14, 15 and carries a packet on a platform 10. Light from a lamp 21 passes through a slot 20 and falls on photo-cells 22 which are connected in a bridge circuit. When the balance of the bridge is upset current is supplied to a coil 16 which moves within a magnet 18 to restore the beam to its neutral position. This current is translated by a differential amplifier 30 into a voltage which may be stored, for example, on a capacitor.

Title: Improvements in or relating to smokemeters
IPC: G01N21/53
Filed: 1952-05-07
Abstract: 704,052. Photo-electric smokemeters. ANGLOIRANIAN OIL CO., Ltd., and WACHAL, A. L. May 7, 1952, No. 11589/52. Class 40 (3) In a photo-electric smokemeter in which light passes from a source at one end of a tube, through which smoke circulates, to a photo-cell at the other, the cell and light source are so mounted that they may be positioned at the ends of a tube through which air is circulated for calibrating purposes. As shown, the light source 24 in a housing 23 and a photo-cell 28 are supported from a horizontal rod 5 so that they pivot about this rod into positions at opposite ends of either the test tube 1 through which smoke is circulated or the comparison tube 2 through which air is passed. The application of the invention to measuring the opacity of engine exhaust gases is described. A sample of the exhaust gases passes through a lagged pipe to a chamber 15 entering tube 1 through apertures 12 and leaving through apertures 18, 18<SP>1</SP>. Tube 1 is lagged to prevent condensation of exhaust water. A supply of compressed air enters tube 2 through a pipe 17 and apertures 13 and escapes into end covers 26, 29 of the apertures. This air then enters the smoke tube through apertures 39 in the light source housing and under the serrated surface of the photo-cell 28 finally escaping to the atmosphere through apertures 18, 18<SP>1</SP>. This stream of air prevents the exhaust gases from contacting the light source or the photo-electric cell. When the cell and light source are positioned at opposite ends of the comparison tube the reading of the micrometer is eventually adjusted to a fixed value by means of a rotatable "spade" 27 situated in the air tube.
