IPC: D04B15/74
Filed: 1970-11-16
Abstract: 1305126 Knitting machines E MAYER [trading as MAYER & CIE] 16 Nov 1970 [24 Nov 1969] 54361/70 Heading D1C In a circular knitting machine having longitudinally movable tilting jacks each having at least one butt acted on by pattern slides actuated by pin drums, there are at each knitting system two selecting locations staggered in the direction of rotation of the needle cylinder and pairs of jacks 10, 11 are inserted in adjacent tricks which differ by having working butts 103, 113 of a different width but have pattern butts 101, 111 at the same distance from the working butts, the needle jacks acting on the needles via intermediate jacks 12, 13 with differently located working butts 121, 131. As shown, jacks 11 have an additional lower butt 114. The two sets of pattern slides 40, 41 may be actuated by different pin rows of a single pin drum. If needles 14/1 (associated with jacks 10, 12) are to remain unselected while needles 14/2 (associated with jacks 11, 13) are to knit, all jacks 10, 11 are swung outwardly before the first selection at which all jacks 10, 11 are pushed in with their butts 102, 112 out of range of cam 35. Cam 34 engages wide butts 113 and raises these lacks so that butts 112 engage part 36 of cam 35 and butt 114 engages cam 39 and jacks 11 are swung outwards for selection by slides 41. Those not selected are raised and with them associated jacks 13 so that their butts 131 almost touch the lower edge of cam 32. When the butt 112 of jacks 11 engage the edge of cam part 37, butt 131 is raised over divider 251 and the jack closes the gap 15 between it and its associated needle 14/2 which is guided with its butt 141/2 along cam part 16 to knitting position. Jack 11 is restored by cam 33

A spring 31 is fixed between the flange 27 and one of the pins 29. Subcarrier plates 35, pivoted at 36 on the base plate 22 are mounted on either side of the drive lever 28. Each subcarrier includes an eccentric offset 37 pivotally connected at 38 with a link 39 itself pivotally connected at 39A to the drive lever 28. Each sub-carrier carries a shaft 40 which extends through an arcuate slot in the ball-rolling panel to support one of the bumpers 20A or 20B. Either of the bumpers is pivotable independently about its own axis 40 by a further mechanism which includes a short crank 42 pivoted to shaft 40 and to plunger 44 of a reprojecting solenoid normally urged outwardly of the bore of the solenoid winding 45 by spring 46 to the limit permitted by a stop 47. A pin 48 actuates a supervisory shortcircuiting switch means by engaging blade 57 to separate it from its companion blade 58 when the crank is pivoted to swing its bumper in response to the reprojecting coil 45. The solenoid 45 'has two windings 45A and 45B in series, one of low resistance and the other of higher resistance, the latter being short-circuited 'by the supervisory switch means 57-58. When the driver liver 28 is shifted it may be latched up by a releasable latch lever 50 pivoted at 51 into a normal position by spring 52 where it will remain until the lever 50 is pivoted by energisation of an electromagnet 55. Additionally the ball bumpers 18R, 18G and 18S dispersed on the playfield actuate scoring switches 70, 71 and 72. A ball striking one of the bumpers 18G closes the switch 71 and energises the drive-lever solenoid 24 to shift the lever 28 and pivot the bumper carriers 35 and bumpers 20A and 20B and latched by lever 50. Another ball striking the bumper 18R closes the switch 70 to release the latch lever 50. A returning ball B<SP>3</SP> could also operate this mechanisim by closing switch 78. A score means 80 may be operated by a pin 81 on the end of the drive lever 28.

Title: Audio signal transmitting systems
IPC: H04S1/00
Filed: 1973-11-29
Abstract: 1427607 Generating vibrato SONY CORP 29 Nov 1973 [11 Dec 1972] 55472/73 Heading H4R In an audio reproduction system a signal is fed through a delay device whose delay is controlled by clock pulses and the frequency of the clock pulses is varied to provide frequency modulation of the signals passing through the delay device to cause vibrato in the reproduced signal. As described the vibrato is applied to the signal from a microphone 6 by feeding the signal through a vibrato unit 10 comprising a preamplifier 11 and bucket brigade delay device 12 fed with shift pulses from a generator 15 whose frequency is modulated by a low frequency oscillator 16. The delayed and frequency modulated signal from delay device 12 is passed through a buffer amplifier 13 and low pass filter 14 before addition to the signal from a phonograph 1. In Fig. 1 the variably delayed signal is added to one channel and the undelayed microphone signal is added to the other channel from a stereophonic source 1. In Fig. 5 (not shown) the signal from the vibrato unit (10) is added to both channels, mixed with undelayed microphone signal from an amplifier (7) if desired. Fig. 6 (not shown) is a modification of Fig. 1 in which centre signals of the stereo source are at least partially cancelled by cross mixing in antiphase the signals in the two channels using matrix 6, while in Fig. 7 (not shown) the signal fed through the vibrato unit is derived from the stereo source as the centre, or L + R signal. In a further modification, Fig. 8 (not shown), the amount of vibrato applied to the signal is controlled in accordance with signal level by feeding the frequency control voltage of the pulse generator (15) through a circuit (17) whose gain is controlled by the signal level applied to the delay device (12). In this embodiment the rate of vibrato is controlled by switching in alternative LF oscillators (16 and 26) operating respectively at 7 and 30 Hz.

Abstract: 1418016 Feeding tobacco AMF Inc 20 Nov 1973 [7 Dec 1972] 56623/72 Heading A2C A tobacco feeding device comprises a passage formed from a series of sections decreasing consecutively in cross-sectional area, means for feeding tobacco to the large crosssectional end of the passage and means for withdrawing tobacco from the low cross-sectional end of the passage and means at each section for advancing the tobacco along the passage towards the low cross-sectional area end thereof, the means having projections which enter the tobacco during advance and which effect a drawing out of the tobacco in the direction of advance at each section. As shown, stations I to VI indicate the feed sections of progressively lower cross-sectional area. Each feeding unit assembly 11, 11' consists of one or more feeding units 12 each of which comprises a pair of parallel side plates 14 separated from each other by spacers 16 and a front plate 17 which faces the interior of the converging passage. Front plate 17 houses a pair of rockers 19, 20 mounted for oscillation about a common spindle 22 and having arcuate surfaces facing the passage. Rocker 19 has a pin 24 passing therethrough carried by arm 25, the other end of which is mounted on a crank pin 27 of a gear wheel 28. Rotation of the drive shaft 40 results in rotation of gear wheels 28, 34 carrying pin plunger arms 25, 31. As gear wheels 28, 34 rotate the pin plunger arms advance the pins successively and by reason of the pivoting rockers are caused to carry out a downward swing. The pairs of co-operating oscillating pins have the same frequency but differing amplitudes, so that pin 24 fixes to progress the tobacco while pin 30 draws it out.

Abstract: 1,190,179. Centrifugal separators. PENNSALT CHEMICALS CORP. 2 Dec., 1968 [21 Dec., 1967], No. 56985/68. Heading B2P. In a centrifuge for separating solids from liquid and having a screw conveyor for discharging the solids through ports in the centrifuge bowl and a feed tube 36 for delivering feed material to a feed chamber 38 within the conveyor hub 40 where the feeed material is directed by an accelerator plate 52 towards one or more apertures in the hub leading outwardly into the separating chamber 46 in the centrifuge bowl, the solids are prevented from accumulating in the feed chamber 38 by means of a baffle plate 74 which is disposed in the chamber 38 to deflect the feed material through the apertures 72, thereby avoiding erosion or twisting of the feed tube by the accumulated solids. The chamber 38 is provided with a stainless steel liner 70. The apertures 74 are helically arranged between the flights 42, 44 of the conveyor. The baffle plate 74 is inclined to the conveyor axis and is provided at its inner periphery with a flanged annular member 78 which cooperates with a stationary flanged annular member 76 on the feed tube 36 to deflect inwardly flowing feed material towards the aperture 72, the baffle plate 74 may be flat, curved or of single conic section or may have a helical periphery. The accelerator plate 52 is fitted centrally with a radial vane assembly 56 which cooperates with guide members 58 on the plate to impart radial and tangential velocity to feed material as it discharges from the feed pipe 36. The feed chamber 38 is separated by means of a partition 48 and a seal 62 from an annular space 64 which may serve as a rinse chamber into which washing liquid may be introduced via a tube 66 and flows, with aid of accelerator vanes 65, through at least one radial passeway (shown closed by a plug 68) into a solids-discharging frusto-conical portion of the separating chamber. In a modification, Fig. 3 (not shown), the apertures (72) in the hub are fitted with wear sleeves (84) projecting inwardly and outwardly of the apertures. The flange (77) on the annular member (76) is made of elastomeric material to facilitate its insertion with the feed pipe through the seal (62). In a further modification, Fig. 4 (not shown), the screw conveyor is provided with a double-helical screw flight and the apertures (72), (72') are arranged in a double helix. The baffle plate is made of two parts oppositely inclined relative to the centrifuge axis, each serving to deflect feed material through a different one of the two series of apertures. The centrifuge may be vertically mounted and the bowl may be wholly frusto-conical or partly cylindrical and partly frusto-conical.

Abstract: 1281919 Cathode-ray tubes HONEYWELL INFORMATION SYSTEMS Inc 21 Nov 1969 [27 Nov 1968] 57135/69 Heading H1D [Also in Division G4] Digital data is stored on an electrically conductive, thin magnetic film of a magnetic disc 12 and read out by an electron beam 22. The disc 12 is positioned within a vacuum chamber 10 so as to be rotatable at constant speed by a synchronous motor 13 during recording and read out. Reading.-An electron beam is sent from emitter 21 and normally goes to a Faraday cup 42 connected to a visually indicating beam current meter. On read out, the beam is deflected through collimating devices 25, 27, magnetic field 26, and electrostatic or electromagnetic deflection plates 30, 31 to impinge orthogonally on one lenslet of a matrix or single row 36 of electron "Fly's Eye" lenses. Further deflection voltages applied to each lenslet direct the beam to a particular track on the disc. A negative potential is applied to the disc so that the electron beam is repelled from the disc surface without touching it and returns along path 37 to two detecting plates 38 lying side by side. Depending on the magnetic binary information on the disc the beam is deflected differently so that it hits one or other of the plates 38 (also on Fig. 2, not shown) and a differential amplifier 40 produces binary output signals, for example for a computer buffer. Alternatively one plate 37 only is provided corresponding to one or zero. Each revolution is detected by the magnetic spot as before.

Abstract: 1,173,925. Windowed oven door. GENERAL ELECTRIC CO. 21 Dec., 1966 [23 Dec., 1965], No. 57213/66. Heading A4D. An oven door 15 comprising a window 45 and bolting means, is characterised in that the window may be closed by a movable shutter 78, and a movable interlocking member 99, is provided which is normally in a first position in which it prevents the door from being bolted but is moved by said shutter so that the door may be bolted when the shutter is moved to a position covering the window, meansbeing associated with the bolting means so' that a heat cleaning cycle can only he initiated when the door is bolted. In the drawing, which is a cross-sectional elevation, the door has three main elements, an outer decorative door panel 25, an inner door liner 26 and a floating inner panel 27. The window 45 is constructed so as to be protected from the high oven temperatures of a self cleaning cycle by the shutter 78 which is slidable from a position in the lower part 76 of the door. to the position shewn. A window opening is formed in each of the three elements 25, 26 and 27 i.e. 47, 48 and 49 respectively. The fluid and innermost glass sheet 53 is fixed by means of screws 36 and clip members 64, and sealed by means of gasket 65 sandwiched between the glass 53 and the peripheral edges of the window opening 48. The shutter 78 can be raised or lowered by means of handles 80 extending through slots 81. The door is bolted by operating the handle 96 which causes a locking bolt to swing out through slot 110 formed in the top of the stove and engage a keeper slot 98 formed in the oven door. With the shutter in its lower position, the keeper slot 98 is blocked by the interlocking member 99 so that the bolt cannot be operated. When the shutter 78 is raised to the position whence it covers the window 45, a finger 101 on the shutter engages the interlocking member 99 and moves it against the action of a spring to a position in which the keeper slot 98 is unblocked and the door may then be bolted. The door is held in its raised position by means of spring 92.
