Title: Device for replacing an unloaded spool or rod with a loaded one in  a fabric laying-up machine
IPC: B65H45/103
Filed: 1973-04-13
Abstract: 1367050 Laying fabric M FONIO 13 April 1973 [26 April 1972] 17902/73 Heading D1S [Also in Division B8] A fabric laying carriage for reciprocation over a table 2 comprises a supply station 9 for rotatably supporting a spool 8 or rod carrying a roll of fabric 7, a reserve station 9a for supporting a further spool 8a or rod carrying a roll of fabric 7a, a receptacle 24 for receiving spools 8 or rods discharged from the supply station, downwardly inclined guide means 12 leading from the reserve station to the supply station and thence to the receptacle 24, means to discharge a spool or rod from the supply station and means to disengage a further spool or rod from the reserve station, the discharging and disengaging means being interconnected and operable simultaneously by a single actuating means. As shown, the fabric 5 is fed from the roll 7 on the spool 8 provided with locking cones 25, over a roller 6 to feed rollers 4. A bracket 10 is raised after each layer is laid during the return movement of the carriage. At the end of the forward run of the carriage, the fabric is cut by a device 11. The spool 8 is received in recesses in standards 9 and, at the reserve station, a spool 8a is supported on standards 9a connected to the standards 9 by inclined rods 12. An upwardly-inclined wing-like member 13 is fixed to each standard 9a and cooperates with an arm 15 of a lever 14 to support the spool 8a. The lever 14 is connected by a rod 18 to an operating lever 19 and is retained in the Fig. 1 position by a helical spring 20. An arm 16 of the lever 14 is connected by a rod 17 to a lever 21 pivoted to a standard 9 and which has an arm 22 located beneath the end of the spool 8. Inclined members 23 extend to the receptacle 24. In use, when the spool 8 is empty, the carriage is stopped either manually or automatically and the operator raises the lever 19 to lower the arm 15 to allow the spool 8a to slide down the guides 12. Simultaneously, the lever 21 is turned anti-clockwise so that the arm 22 pushes the spool 8 out of its seating and thence down the guides 23 into the receptacle 24. The spool 8a is prevented from entering the seating in the standards 9 by the arm 23 until the lever 19 is lowered and the lever 14 returned to the Fig. 1 position. The laying operation is recommenced at the same position in which the previous lay was interrupted. When the carriage reaches the end of its run, a fresh reserve spool is mounted on the standards 9a. The carriage may be provided with a plurality of reserve stations arranged in series and, when a fresh roll is fed to the supply station, the reserve rolls each move forward one station.

Title: Method and apparatus for speech transfer over a norrow trans mission bandwidth by means of delta modulattion
IPC: G10L25/90
Filed: 1973-04-13
Abstract: 1433351 Bandwidth compression LICENTIA PATENT - VERWALTUNGS GmbH 13 April 1973 [14 April 1972] 17933/73 Heading H4R In speech bandwidth compression in which spaced sections of the speed signal are selected for transmission, voiced sections are of a length equal to a whole pitch period or to a portion extending between the zero crossing before the energy rich start of a pitch period and a zero crossing before the next pitch period, and unvoiced sections are of a length equal to a mean of the voiced pitch period, the sections being transmitted as delta modulations and being stretched to fill the gaps between sections. The modulated speech 1 is read alternately into stores 3, 4 associated with counters 31, 41 recording which store stages are occupied, at a rate determined by zero crossing detector 21 and read-out at a slower rate for multiplexed transmission 8. A pitch extractor 2 produces a pitch pulse at the start of each word and these pulses are monitored to produce a voicedunvoiced decision for encoded transmission. Characters identifying the start of words and representing the basic pitch frequency are also encoded for transmission, the latter occupying every 40th time slot for synchronization and level control at the receiver. Word storing is only effected when a zero crossing pulse is followed by a pitch pulse, otherwise the stores are reset, and the amount of voiced speech stored (typically 2/3) is controlled by the duration of the pitch period. The various characters are assembled at 7 in the required order for transmission. A signal representing the near pitch period may also be transmitted during unvoiced speech. At the receiver (Fig. 2, not shown) the data is demultiplexed at (18) and read-in to stores (13,14) when a new word character (e.g. 1100 ... 1100) is confirmed. The word is repetitively read-out to fill-in the gaps arising from expansion at the transmitter. The fundamental or mean pitch frequency or a frequency containing random pulses is generated at (12) corresponding to voiced or unvoiced speech. The read-out rate may be controlled according to pitch period signals received to automatically prevent overlaps or gaps in the read-out.

Title: Improvements in or relating to wireless or like receiving systems
IPC: H03G11/00
Filed: 1936-06-29
Abstract: 477,370. Wireless receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 29, 1936, No. 17983. Convention date, June 29, 1935. [Class 40 (v)] The signal to noise ratio of a radio-receiving system is improved by means of a limiter device comprising a screen-grid valve, the screen grid potential being higher than that applied to the anode, and which is preceded by a broadly tuned amplifier and followed by a sharply tuned amplifier. Fig. 1 shows the radio frequency amplifier 5 and frequency changing stage 7 of a superheterodyne receiver, the amplifier having a pass band of the order of 50 kc. in width obtained by series resistances 169. The output from 7 is applied to a broadly-tuned I.F. amplifier comprising three tunably coupled stages 27, 29, 31, the input circuit 19 of valve 27 having associated therewith a manual selectivity control comprising a coupled circuit 153, 159 put in or out of effective operation by switch 155. The output level from amplifier 31 is adjustable manually at 161, the volume being kept constant as regards signal variations by the A.V.C. system 144 ... 148 coupled to the input of amplifier 31. The output from 31 is applied to a pentode limiter 35 operating by anode voltage saturation and anode current cut-off by virtue of the anode voltage being considerably less than that applied to the screen grid. The range of limitation is controlled at 47. The limiter is resistance-coupled over network 67, 73, 77 to a further I.F. amplifier 33, the output of which is sharply-tuned to a band width of 5-10 kc. and this output is applied to a diode-pentode 89 constituting the audiofrequency rectifier and first audio amplifier of the receiver. The invention rests on the fact that in broadly tuned-circuits, static discharges and similar interference are of high amplitude and short duration while the converse is the case for sharply-tuned circuits; the length of the decay train is inversely proportional to the band width. The effect of the limiter following a broad amplifier is thus to limit the amplitude of a short decay train while that of a sharp amplifier following the limiter is to extend the duration of the interference ; its amplitude being thereby further reduced.

Abstract: 574,019. Blind riveting. DILL MANUFACTURING CO. Nov. 2, 1943, No. 18130. Convention date, Feb. 24. [Class 43] [Also in Group XXV] A tubular member for use in blind riveting is collapsed by relative motion between parts of the device to form an eyelet. In the form shown in Fig. 2, the device comprises three parts, (1) a sleeve 20 flanged at 21 and provided with a series of slots 22 and with a weakening groove 24; (2) a sleeve 26 both externally and internally threaded, flanged at 27 and provided with screwdriver notches 33, and (3) a sleeve 34, with a closed end, screwing on to the sleeve 26 and bearing against the end of the sleeve 20. The closed end has a slot 36 for a rotating-tool. The flanges 21, 27 have interengaging V-recesses and projections respectively. The parts assembled as in Fig. 2 are passed through the members 38, 39 and the sleeve 26 is held by the notches 33 while the sleeve 34 is rotated by a tool which engages the slot 36 causing the strips 23 between the slots 22 to bend at the groove 24 and ultimately to collapse and grip the parts 38, 39 against the flange 21 as shown in Fig. 3. A screw engaging the threads 32 may then be used to attach another part or fitting. The end of the sleeve 26 is reduced and slotted at 31 to exert a spring gripping action on the screw. If the threads 32 become damaged the sleeve 34 may be unscrewed permitting removal of the sleeve 26, the sleeve 34 falling and remaining within the structure. It is replaced by a sleeve 40, Fig. 9, adapted to be expanded at 41 after insertion through the eyelet-like collapsed sleeve 20 by a conical shoulder on a flanged sleeve 44 otherwise similar to the sleeve 26. In a modification, the sleeves 20 and 34 are integral.

Title: Improvements in automatic railway signals and stops
IPC: B61L3/04
Filed: 1924-07-30
Abstract: 224,481.. Zukor, A. July 30, 1924. Hydraulic systems, automatic; track apparatus for actuating track contacts and signals on and other than on trains and for stopping trains.- In a system whereby a train automatically protects itself against a following train the line is divided into sections and at the junctions of adjacent sections are placed track devices each comprising a casing with independent vertical cylinders 22, 23 in which slide pistons 27, 28 respectively carrying a stop bar 25 and shoe 30. Each shoe cylinder 23 is connected by hydraulic piping with the cylinder 22 of the stop to the rear. Normally, the shoes are raised and the stops 25 are lowered. A roller 61 carried by the passing train depresses the shoe 30, so protecting the train by raising the stop 25 to the rear. The stop, when raised, co-operates with pivoted levers 60, 62 on a following train, which respectively ring warning bells 58, 59 and control the throttle valve to stop the train. Arrangement is made whereby raising a stop also (raises the adjacent shoe, but the shoe can be depressed without lowering the adjacent stop. The following train can thus depress a shoe to protect itself to the rear, without affecting the adjacent stop if the latter has been raised by a train ahead. An arm 35<1> on the stop rod 26 engages under an arm 35 on the shoe rod' 29 so that raising the stop 25 also raises the adjacent shoe 30. The arms are pivotally movable on the rods, and are urged against a vertical face 44 (over which they slide) by springs not shown. At the upper limit of travel, the arm 35 snaps through an aperture, in the face out of register with the arm 35<1>, as shown in Fig. 7, and when the shoe is depressed the arm 35 travels down an inclined channel 45 leading it back to the bottom of the face 44. On subsequent depression of the stop 25, its arm 35<1> rides over, and snaps into place below, the arm 35, the arms being bevelled as shown to facilitate this riding action. A gate 4& opening outwards at the lower end of the channel 45, prevents the arms from entering the channel during upward movement. The shoe may be held in raised position by a catch 49 released by the roller 61, and the stop may have a spring 47 tending to hold it up. Raising a shoe effects lowering of the connected stop to the rear by suction action. If desired, the stops 25 may have pin-and-slot connection with a lever 67, Fig. 3 serving to set a signal to danger when the stop is raised. As shown, the signal comprises a fixed plate in which stencils of the words " Go " and " Stop " are cut. The lever 67 operates, through a link 70. a pivoted arm carrying a luminous disc 73 which shows through one or other of the stencils according to the position of the stop.

Title: Electronic control for die casting machines
IPC: G05B19/06
Filed: 1948-07-08
Abstract: 748,431. Casting-machines. SCHULTZ DIE CASTING CO. July 8, 1948 [Dec. 10, 1947], No. 18408/48. Class 83 (1). A die-casting machine comprises die opening- and-closing and metal-injecting means actuated by fluid-pressure controlled by electricallyoperated valves arranged in electric circuits containing a number of electronic-discharge valves normally biased to prevent firing, and means for removing the bias to permit firing of the valves sequentially to effect the closing of the dies ; a slow injection of metal followed by a rapid injection ; the opening of the dies, and finally the resetting of the bias circuits for a repetition of the cycle. The opening and closing of the dies A, B is effected by pinion 54a and connecting rod 47a actuated by a rack 59a reciprocated by a piston 60a driven by oilpressure controlled by the valve 63a actuated by an electromagnet 30. When the rack is raised to close the dies a switch 27a is closed, thereby permitting the injection of metal into the dies from the gooseneck. The injection is effected by a pneumatic cylinder 32a whose main control-valve 84a is rotated by gearing from a shaft 83a which is operated by another pneumatic cylinder 333 whose control valve is actuated by an electromagnet 51. The injection is slow or rapid according to whether a regulating-valve 142a is opened by air pressure supplied from a pilot valve 61a operated by the electromagnet 61. One form of control circuit, Fig. 6 (not shown), includes five electronic valves, each having a time-delay network in its grid-circuit and being normally biased to cutoff by a main bias supply. The removal of the bias from one valve causes it to fire and energize the electromagnet 30 to close the dies and the safety switch 27a, which allows the removal of the bias in sequence from three other valves to energize the magnets 51, 61 and then to deenergize both. The firing of the last valve opens the dies and rebiases the other valves. A modified form of control circuit using four valves is also described. Specifications 428,115, 437,227, 701,787, 748,432, [Group XL (c)], and 748,433 are referred to.
