Title: An antenna for a strip transmission line
IPC: H01Q13/10
Filed: 1970-10-21
Abstract: 1285289 Aerials TELEFONAKTIEBOLAGET L M ERICSSON 21 Oct 1970 [23 Oct 1969] 50046/70 Heading H4A A wideband aerial comprises a portion of strip transmission line with an axially-extending planar inner conductor 1, Fig. 1, and at least one planar outer conductor 11, with intervening dielectric material 4. A plurality of parallel elongate slots of different lengths is provided in an end section of the outer conductor, which cross the inner conductor, and which are not parallel to its axis. Each slot is matched for a particular frequency such that its length is an integral multiple of the corresponding wavelength, and its distance from a corresponding part of the end of the inner conductor is an odd integral multiple of a quarter of this wavelength. The slots may be so closely spaced that they are contiguous and merge into a single slot (Fig. 2a). As described, a second planar outer conductor 6 is spaced from the other side of the inner conductor 1 by dielectric material 3. Near the end 8 of the inner conductor 1, the dielectric material spacers and the outer conductors are extended laterally into two oppositely directed arms. In the space thus provided radiating slots 7a to 7f are made in either or both of the outer conductors, so that they lie across the inner conductor. In other embodiments in which the slots are continguous, so that they merge into a single slot, the ends of said slots are shaped to form a smooth curve, instead of steps (Figs. 2b, 2c, not shown). The lengths of the slots may be arranged to decrease on each side of a central slot, instead of on one side of an end slot (Figs. 3a to 3d, not shown). The end of the inner conductor may be of stepped formation instead of being squared off (Fig. 4, not shown).

Title: Dc signal receiving circuits
IPC: H04B3/04
Filed: 1974-11-20
Abstract: 1482798 Data transmission; distortion correction SIEMENS AG 20 Nov 1974 [4 Dec 1973] 50208/74 Heading H4P A time distortion correction circuit for incoming pulsed signals comprises a double threshold circuit SW coupled to an input circuit EK and to a timer ZG, the output of the input circuit and of the timer being coupled to a circuit AK such that when incoming signal level changes in either direction and passing through both threshold values, on passing through the first the timer is started and on passing through the second value the state of the input circuit is changed at the end of a determined time the timer causes the circuit AK to change in correspondence with received D.C. signal level. Short disturbance pulses are eliminated in the arrangement by threshold values S1, S2 and by protection period ts, which effectively time displaces incoming signal by such periods. The circuit SW has upper level S 1 and a lower level S2 with outputs giving 0 when each is exceeded. Normally line L input is high and an information bit causes such level to drop first through S1 which gives a 1 output but bi-stable circuit EK does not change; a 0 is emitted by gate G3 so that 1 is produced at gate G5 output hence timer ZG is triggered i.e. protection time ts commences. When S2 level is undershot, EK changes and emits 0 which passes as a priming signal to bi-stable stage AK which is triggered to opposite state on expiry of ts; the timer is then reset via G4, G5. On a rising signal, initially S1, S2 have 1 outputs. On passing S2 level, B gives 0, and A remains at 1 which inverted through G2 causes gate G3 to start the timer. When level S1 is passed A-#0 hence input EK = 1 giving a priming 0 to AK which is set by timer ZG output at termination of period. Timer is then reset as before. Fig. 3 (not shown) and related description explains how the arrangement will operate on signals giving rise to decayed oscillations. The arrangement may also be used with double current signals by appropriate modification of the circuit, e.g. by adjustment of threshold levels.

Abstract: 986,607. Bundling machines. GERRARD WIRE TYING MACHINES CO. PROPRIETARY Ltd. Dec. 31, 1963 [Jan. 29, 1963], No. 51405/63. Heading B8C. Bundles, e.g. wool bales, are tied by a number of straps 9 simultaneously while compressed between platens 6, 7, each strap being fed by a driven roller 19 so that it is passed round the bundle to a gripper 62, tightened by a driven roller 33 severed by a blade, Fig. 10 (not shown), and joined by jaws which crimp a seal blank round overlapped portions 9c, 9d of the strap. Each bale is supplied to the lower platen 6 from a conveyer 3 and slide 8, Fig. 1. A door 16, having guide grooves 49 for the straps, is moved pneumatically against the bale, Fig. 2, when the bale breaks a light beam on arrival at the platen 6, which is raised automatically a predetermined distance to compress the bale. The strap 9 is fed round the bale when eccentric bushes 24 of an idler roller 18 are turned, thereby forcing the strap against the driven roller 19. The strap is fed through a crimping mechanism 72 and into a groove 52 of the lower platen 6. Spring-loaded bars, Figs. 8-9 (not shown) hold the strap within the groove 52 until tensioning takes place. A similar groove is formed in the upper platen 7. The mechanism 62 for gripping the strap end includes a spring-loaded roller, Figs. 11-13 (not shown), which is wedged against the strap when the tensioning rollers 32, 33 operate. A ram is actuated to crimp the seal blank on to the strap which is first gripped by a pad, Fig. 10 (not shown). A part 13 of strapping head 11, on which part the crimping mechanism 72 is mounted, is pivoted sideways about a point 14 to enable the overlapping parts 9c, 9d of the strap to be removed from the crimping mechanism. The strapped bale is lowered on the platen 6 for ejection by hydraulic bars 101, Fig. 1, on to a discharge conveyer 4.

Abstract: 1,190,381. Seaming. WILLIAM GARFIELD Ltd. 15 Sept., 1967 [16 June, 1966; 17 Nov., 1966], Nos. 26926/66 and 51506/66. Heading B3J. [Also in Division B8] Apparatus for filling and sealing a container, which may be of metal foil, includes sealing means comprising displaceable platens and dies for clamping together a lid and a peripheral flange on the container, and for effecting telescopic motion, first to fold the clamped parts downwards, and then to roll them together in a return movement. Feeding and filling containers.-Pre-formed flanged container bodies 10, placed successively on a platform 81, Fig. 1, pivoted at 82, operate a switch 83 causing a stroke of cylinder 55 coupled to parallel reciprocable rods 53, (54). Conveyer fingers 70 pivoted on the rods push the container 10 along a guideway 72 as far as charging station 85, where the container is filled with the desired contents. The fingers 70 pivot into ineffective positions during the return stroke. Sealing containers.-A stack of foil lids 11 is held in a magazine 44, and movement of the rods 53, (54) causes a platform 48 on a carriage 42 to advance after removing the bottom lid 11 from the stack by means of a suction pad 43. The platform 48 is caused to pivot as necessary by pneumatic means 52. Actuation of a trip finger 58 then causes the carriage to place the lid 11 against a second suction pad 41, Fig. 3, which retains the lid because of vacuum interchange between the two pads, and the carriage 42 returns to its initial position. The pad 41 is mounted on a platen 21 above a fixed die 13 into which a container has been pushed by fingers (88), Fig. 2 (not shown). The die 13 is surrounded by an outer die 14 on which the flange of the container rests, and which is provided with an annular groove 15. A further platen 22 is arranged above die 14. A ram 25 causes the platens 21, 22 to move downwardly, clamping the lid 11 with the container flange, and further downward movement produces telescopic motion of platen 22 and die 14 about platen 21 and die 13, causing the flange and lid periphery to fold downwards, forming a skirt (30), Fig. 5 (not shown). When the pressure of the ram is released, a spring 19 causes die 14 to rise with platen 22, thus rolling together the lid and flange within the groove 15 to form a rolled seam 33, Fig. 6. The sealed container is now ejected by a ram 63 prior to the arrival of a fresh container for sealing.

Abstract: 1405497 Automatic voltage regulation RCA CORPORATION 8 Nov 1972 [2 Dec 1971] 51547/72 Headings G3R and G3X A voltage regulator circuit includes two transistors connected as a differential amplifier and biased respectively by a reference potential and the circuit output voltage. The first transistor is connected in series with a constant current transistor and supplies a control signal to a further transistor connected in series with the circuit output. As shown, a COS/MOS integrated circuit includes a reference voltage generator 50 and a regulator circuit 51. The generator comprises Zener diodes Z 1 , Z 2  and field-effect transistors N 1 , P 1 . A further FET P 2  ensures stable operation of the generator circuit which supplies reference voltages for the regulator 51 on lines 12, 13. The voltage supplied at a terminal 14 to a load is controlled by an FET N3 which is made more or less conductive according as the relative voltages on line 13 and at terminal 14 cause FET P 4  or FET P 5  to be conductive. Thus transistors P 4 , P 5  form a differential amplifier receiving current from source transistor P 3  which delivers a substantially constant current. Transistor N 2  also forms a constant current generator and presents a high impedance to signal currents, thus producing a high loop gain. The circuit is constructed so as to provide a temperature-independent voltage output.
