Title: Circular knitting machines
IPC: D03C17/06
Filed: 1970-07-24
Abstract: 1321255 Program controlled knitting machines ETUDES ET BONNETERIE S A 24 July 1970 [31 July 1969(2)] 36033/70 Heading G3N [Also in Division D1] A circular knitting machine is controlled by a film 8 containing information strips 13, 36 in bit form. The information is stored in a memory 34, and signals on line 37 enable the release of the bits of information to the coils of the selection members 7, 7a, 7b via amplifier 44 at a frequency equal to that of the passage of needles 3 past the selection members 7, 7a, 7b, determining whether a needle will be raised by a cam working against jack 4. The film 8 has a track for each selection member, and a timing track 36 whose output 35 is fed to a counter 45 which controls the speed of D.C. motor 23 as a function of the difference in the number of counts on lines 35, 37, so that the capacity of the memory 34 receiving bits of information on lines 13a, 13b is never exceeded, sufficient information always being stored to ensure continuous operation of the machine during the reversals of the film. The reader 33 has an output channel for each track on the film. The signal on line 37 is obtained by interrupting a light beam to photo-cell 38 by perforated disc 40 driven via crownwheel 43 which also drives the needle cylinder 1 containing the needles 3 in grooves 2. The film 8 has perforations (14) Fig. 3 (not shown) engaged in sprockets (15) Fig. 2 (not shown), and the drive to the spools is taken via electromagnetic clutches 11, 12. In an alternative embodiment, Figs. 4-6 (not shown) the film passes over spaced discs (50, 51) containing between them a light channel (59) which passes light through the film at (60) to a reader (62) with photo-cells (63). Motor (23) Fig. 6 (not shown) drives one of the discs, and motors (66, 67) Fig. 4 (not shown) drive the spools. Tensioning rollers (68, 69) Fig. 5 (not shown) on resilient rubber arms (70, 71) are provided, and the film contains reversing information to de-energize motors (66, 67) before motor (23) is reversed. The path of the film is indicated in Fig. 5 (not shown), (57, 58) being pressure rollers. Fig. 7 (not shown) displays the film which has bits of information A 1  - A n , R, - R n  which are scanned in transverse lines by reader (62) during advance or return motion of the film respecitvely, each track 1-12 corresponding to a selection member. (T) is the timing track, and the passage from opaque to transparent zones on track (T) triggers the reading of the bits A 1  ... A n  for forward motion, or the reading of the bits R I  - R n  in reverse motion. The passage from transparent to opaque may alternatively trigger the reading process. Track B contains information for reversing the tape drive, and the track B I  causes the de-energization of the motors (66, 67) Fig.4 (not shown). The film may be endless. A tape may be used instead of a film.

A switching arrangement comprises a number of rows of crossing points for connecting subscribers' lines to intermediate lines and a further row of unmultipled crossing-points for connecting an intermediate line to the associated outgoing junction line. The arrangement is shown schematically in Fig. 1. The subscribers are arranged in subgroups TGr1-TGr10 and each pair of sub-groups is associated with ten intermediate lines such as ZL1-ZL10 and the associated outgoing junction lines VL1- VL10. Each pair of sub-groups comprises 19 subscribers' lines such as Tn11-Tn29, each associated with a horizontal row of crossing points such as k11/1- k11/10. Each crossing-point consists of four contacts of magnetic type. An additional row of crossing-points k20/1-k20/10 is unmultipled. When a call is initiated on subscriber's line Tn11, a control device SE (Figs. 3, 4 and 6, not shown) operates to identify the calling line and its sub-group. The control device also selects a free intermediate line, say ZL1, and associated junction line VL1. The control device then energizes selector coils X11, X20, Y1, Y11 corresponding respectively to the calling line, the unmultipled row of cross-points, the switch to which the calling line is connected, and the switch to which the junction line is connected. Contact sets k11/1 and k20/1 close and connection is thereby made from the calling line to the junction line. The control device then energizes holding coils Ht1 and Ht11 and restores the selector coils. For incoming traffic use is made of a reduced number of intermediate and junction lines.

Title: Seismic impulse generation
IPC: G01V1/104
Filed: 1971-08-04
Abstract: 1335320 Seismic energy generators AMOCO PRODUCTION CO 4 Aug 1971 [5 Aug 1970 14 Dec 1970] 36692/71 Heading H4D A seismic impulse is generated in the earth by screwing a hollow tool to a depth below the surface and exploding a gas mixture in a cavity created in the earth at a region of the passageway formed by the tool, the gas mixture being introduced into the cavity via the tool. In the embodiment of Figs. 14A-14D, the tool comprises an auger 138 on a piston 134 which is slidable in hollow shaft 122 and retained by pin 136 in slots 132. The tool is screwed to the required depth as in Fig. 14A, then backed off a turn or so as in Fig. 14B to open slots 132. A preliminary gas charge is exploded to form cavity 55, as in Fig. 14C, which then constitutes the combustion chamber for repetitive explosions of further charges (of, e.g., oxygen and propane) to generate seismic impulses. In the Fig. 15A-15D embodiment, a sliding member having channels 80 and a bit 83 normally closes the lower end of the hollow tool while it is being screwed into the ground by handle 61 (Fig. 15A). A preliminary gas charge is exploded to eject bit 83 and form cavity 55 (Fig. 15B) and so provide the combustion chamber for subsequent impulse-generating explosions. A gas mixing and firing chamber 92 (detailed in Fig. 8, not shown) is detachable from the tool. In a third embodiment (Figs. 1 to 4, none shown), the tool comprises an auger around the lower end of a hollow shaft and is driven into the ground by an hydraulicallyoperated, truck-mounted derrick. The truck also carries gas supplies and gas filling, mixing and firing controls. The cavity (55) is formed by partly withdrawing the tool while rotating it to compact the earth above the auger. Prior to initiating the impulse-generating explosions, when using the above tools, a viscous liquid may be injected by compressed air into the cavitv to seal porous earth formations. After each explosion spent gases may be vented to atmosphere through a valve or allowed to dissipate into the earth formations. Several tools may be used in a pre-selected pattern and can be fired simultaneously or sequentially. Gas filling and firing can be controlled automatically from a remote location.

A rotary internal-combustion engine of the n and n+1 lobe type is arranged for 6-cycle operation, the residual gases from the Otto 4-cycle series being expanded and exhausted through an additional exhaust port. In Fig. 1 (which is a kinematic inversion of an arrangement described in Specifications 791,689 and 866,307, in which both bodies are rotors) a stator 1 in the form of a three-lobed epitrocloid surrounds a four-apex rotor 2 journalled on and geared to an eccentric 53<SP>1</SP> coaxial with stator 1, the angular velocities of rotor and eccentric being in the ratio 1 : 4. The rotor apices (which carry sealing-members 3) co-operate with the stator to form four working chambers V 1 , V 2 , V 3 , V 4 . The stator 1 is provided with fuel inlet port 4, exhaust port for pressurized hot gases 5, outlet for re-expanded residual gases 6, and fuel ignition means 7. The rotor 2 has cavities C in its periphery by means of which the working fluid is passed over the lobes of the stator in the course of successive cycles, described fully with reference to Figs. 2-48 (not shown). In an embodiment (Fig. 49) the engine is associated with a compressor and comprises a shaft 52 carrying an eccentric 53 whereon is journalled a rotor 2<SP>1</SP>. Gears 55, 561 maintain relative angular velocities of eccentric and rotor at 4 :1. A carburetter 51, inlet pipe 5a, exhaust outlet 58 and additional port 6 (Fig. 51, not shown) and duct 57 for re-expanded residual gases are provided. Counterweights 95, 96 are splined to shaft 52 and there is a power outputshaft 78. Cooling liquid may be circulated through passages 59. The compressor portion of the combination consists of an inner rotor 61 with two apices journalled on a stationary drum 60 having inlet and outlet ducts 68, 69. The inner rotor 61 co-operates with the epitrochoidal inner surface of an outer rotor 62 (see also Fig. 50, not shown) which is rotated at twice the speed of inner rotor 61 by gearing 64, 65, 66, 67. Ambient air is drawn in through 68 and may be expelled through 69 direct into the working chamber of the engine close to exhaust port 5 for scavenging and cooling purposes or may be mixed with the exhaust gases. The construction may be applied as a heat generator for a gas turbine and is arranged to be conveniently compact for mounting thereon. In this case the residual power output of the engine may be utilized by coupling power output shaft 78 to the turbine. In another embodiment of the engine (Figs. 52, 53, 54, not shown) the outer rotor is shaped as a six-lobed epitroshoid, the inner rotor has seven apices, and the ratio of their respective angular velocities is 7 : 6.
