Title: Time Shared Automatic Machine Tool Control System.
IPC: G05B19/418
Filed: 1967-10-16
Abstract: 1,159,799. Programmed control of machine tools. BUNKER-RAMO CORP. Oct. 16, 1967 [Oct. 26, 1966], No. 47017/67. Heading G3N. A plurality of machine tools are controlled from a central location by a system having a memory device for storing a plurality of addressable programmes each of which comprises numerical machine tool control data for directing the operating a machine tool, signal. As shown, a memory 32 of a central processor stores a plurality of programmes for performing machining operations on workpieces. Each programme comprises segments representing motion in a given direction along a straight or curved path, the segment being changed when the end of the path is reached. The machine shops 14-18 are connected to storage register 20-24 into each of which is set the address of the initial segment of a desired machining programme. Each register has a set of address gates 26-30 capable of interrogating the memory 32 when enabled by the output of an AND-gate 34-38 which is enabled by a clock pulse from a source 40, a cyclic pulse CNTR1-CNTR3 from a counter 42 and a data request signal M1-M3 from a converter circuit 44-48. The storage registers 20-24 are incremented for successive programme segments by the enabling pulses from gates 34-38 through an inverter 50-54 and a one shot multi-vibrator 56- 60. The cyclic counter 42 is advanced by an AND- gate 62 enabled by the clock pulses, the data request signals M1-M3, through an OR-gate 64, and signals U1-U3 derived from the signals M1- M3 through an AND-gate 72-76, enabled by the cyclic count pulse CNTR1-CNTR3, and an inverter 66-70. The memory 32 is interrogated for each machine shop by a set of READ gates 78-82, enabled by AND-gates 84-88 responsive to the clock pulses and cyclic pulses CNTR1-CNTR3, to transfer motion command and instruction words to the converter circuits 44-48. The converter circuits change the words into pulse trains and sends them to associated time converter circuits 90-94. Each time converter circuit sends a signal to its associated converter circuit when it is ready to measure the pulses over a predetermined time interval and this timed data is then transmitted to the machine shop on the receipt of a request for data and also sends an enable signal to the converter circuit to instruct it to send the next pulse train. The timed data to the machine shop is stored and used by the servo control system of the machine tool. The initial programme addresses to storage register 20-24 are set in from card readers located in the machine shops.

Title: Energy Wave Fracturing of Formations.
Inventor: BRANDON CLARENCE WILLIAM
IPC: E21B7/18
Filed: 1966-12-29
Abstract: 1,175,187. Wells &c. C. W. BRANDON. 29 Dec., 1966, No. 47322/66. Heading E1F. A method of increasing fluid flow through a subterranean formation penetrated by a wellbore consists in applying a column of fluid to the intrusion of the bore upon the face of the formation, subjecting the fluid to a first pulsating action to produce a first sonic wave whereby the pressure of the fluid varies above and below the internal pressure of the formation immediately adjacent the face, and imposing periodically a further pulsating action on the fluid to produce a further sonic wave, during the latter impositions adding and/or withdrawing fluid to or from the column to augment the energy contour of the resultant wave formation during compression and/or rarefaction respectively, thereby to cause uplift, breakdown and fracture of the formation by the applied pressure and rupture and disintegration of the face of the fractured formation by release of the applied fluid pressure from the internally pressured formation. Fig. 8 shows the first sonic wave 1462 with the further wave 1468, 1470, fluid being added at 1380 and withdrawn at 1381 so that the further and first waves are in phase. By changing the times at which the fluid is added or withdrawn, the further wave may be given a leading or lagging phase shift with same loss of total energy (Figs. 9, 10 not shown). The first and further sonic waves may be produced by apparatus described in U.S. Specifications 2,886,509 and 2,796,129. The method may be applied to tunnelling horizontally between two well bores, or to a single well bore to form a chamber from which oil is withdrawn. This chamber, when exhausted is filled with cement and a second chamber is formed thereabove and the oil withdrawn therefrom. This action is repeated to recover oil from a succession of vertical chambers.

Abstract: 1,043,120. Labelling machines. SULHIST Ltd. Dec. 2, 1964, No. 48944/64. Heading B8F. A machine for labelling loaves or other articles being advanced by an endless belt conveyer comprises means for advancing the labels supported on a backing web to an application point and separating them there from the web. Detectors for the labels and articles combine to control the label feed. A printing mechanism may be mounted on the machine. A label web 32 passes from a spool 30 over a platform 2, freely pivotable in a vertical plane but normally held inclined by springs 20, 22 on a rod 12, to a label stripping roll 50 from which the labels pass under a nozzle 56 and the web passes to a take-up roll 100. The web is fed by rolls 78, 80 driven under the control of an electromagnetic clutch and brake. A label detector 42 including a photoelectric cell is longitudinally adjustable along the platform 2 and a similar detector is provided for the articles on the feed conveyer. As an article contacts a shoe 52 raising the platform 2, its detector starts the web feed and a label becomes separated and is advanced at the same speed as the article under the nozzle 56, where an air jet applies the label. As soon as the detector 42 detects the gap between labels it stops the feed until the next article arrives.

Title: Improvements in or relating to Combine Harvesters
IPC: A01F12/10
Filed: 1967-10-31
Abstract: 1,193,697. Combine harvesters. INTERNATIONAL HARVESTER CO. 31 Oct., 1967 [31 Oct., 1966], No. 49408/67. Heading A1F In a combine harvester of the type comprising an axial flow crop thresher the unthreshed crop is fed into the cylindrical member from a cowling. The cowling which is wider than the cylinder is attached to the latter along lines 52, 53, 58, 56 and 69. The crop material is fed on to platform 80 which is at a level above the axis of the cylinder, from a conveyer 15 and urged into impeller fins on the rotor (not shown) by transverse beater 18. The crop is directed inwardly by the contour of the cowling, this being characterized by a summit 51, apexes 54, 55 and cowling platforms 67, 73. The construction is such that platform 67 is below the cylinder axis while plate 73 is above, at the level of platform 80. In Fig. 6, the rotor is arranged to rotate anticlockwise so that crop from platform 67 encounters impeller blades moving downwardly, and from platform 73 it encounters upwardly moving blades. As crop from platform 67 moves up the opposite side of the cylinder it is directed by stripper blade 90 rearwardly of apex 55 to ensure that it cannot back feed. The crop from platform 73 is prevented from moving forwardly out of the cowling by deflector flange 82. The first of the transport fins 29 starts on edge 64 to the right of point 51 (Fig. 6) and extends rearwardly beyond apex 54. Because crop from platform 67 can travel in excess of 180 degrees while that from platform 73 must reach apex 54 in less than 180 degrees, apex 55 is located forwardly (towards summit) of apex 54. Air, carrying dust and chaff created by conveyer 15 and beater 18, follows the same path as the crop through the cylinder so minimising the problem of dust backing down the feeder.
