Title: Improvements in and relating to the planting and transplanting of the seedlings of plants
IPC: A01C11/02
Filed: 1929-07-27
Abstract: 337,412. Hisnichenko, P. A. July 27, 1929. Planting-machines; manure distributers.-Selfcontained turf-like sections of prepared soil containing growing seedlings or plants to be transplanted are placed on a transportable planting machine which divides them into small rectangular clods and deposits them in furrows made by ploughshares on the machine. The sections are placed on shelves 1 and are transferred to a conveyer band or chain 3 by the operator standing on a platform 2. The conveyer is driven intermittently by a pawl and ratchet wheel 4 and delivers the sections to a rotary cutter 5 which is reciprocated by crank mechanism so as to cut the sections into transverse strips. The cutter 5 is rotated by means of a toothed rack forming a guide. Chain-driven rotary cutters 7 divide the strips into rectangular clods which pass down tubes 8 into furrows made by shares 9. The furrows are filled up by earth boards 10 and the soil rolled by rollers 11. Solid or liquid fertilizer may be fed intermittently to the shoots 8 from a drum 12. The tubes 8 may be fixed in substantially vertical positions and may have their lower ends open rearwardly for the escape of the clods, or they may be arranged to move relatively to the machine in such a manner as to be stationary with respect to the ground as the clods are deposited.

Abstract: 830,181. Railway signalling systems. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. July 24,1957 [July 27, 1956], No. 23408/57. Class 105. For railway signalling purposes, such as with continuous rails not divided by insulation or for the control of a level-crossing signal by a train while in a short length of track superimposed so as to speak in an insulated block section, use is made of an oscillating circuit feeding the rails, wherein the rails act as inductance components of such circuit, the oscillating circuit including a valve or transistor device 12 and a transformer-condenser circuit 11a-14 feeding into the rails and a similar transformercondenser feedback circuit 10b-15 for the device 12. A train moving in the right-hand direction shown by the arrow will, on reaching the position shown by the short-circuiting axle c-d, Fig. 2, have sufficiently detuned the circuit comprising the rail inductance and transformer-condensers to cause a relay 13 controlled by the oscillating circuit to drop. The detuning will continue until a position denoted by the short-circuiting axle a-b is reached. With a steel-sleepered track the control section providing the track circuit section is provided with wooden sleepers and is bridged by short-circuiting links 23, 24, Fig. 4, at the ends of that section. The length of rail circuit 17, 17<SP>1</SP> between the feedback connections 3, 4 and the associated end 23 of the levelcrossing control section may be bridged by a condenser 25 to give a rejector-circuit effect.

Filed: 1976-06-08
Abstract: 1528851 Modified starch CELLCOR CORP OF CANADA Ltd 8 June 1976 [10 June 1975] 23535/76 Heading C3U [Also in Division B1] Modified starch is obtained by continuously mixing a slurry of starch into a tubular heating zone at a pressure of at least 20 kg./cm.<SP>2</SP> and at a temperature sufficient to cause the starch slurry to at least partially gelatinize and thereafter form into a hot starch liquid while moving through the heating zone; continuously passing the pressurized hot starch liquid from the heating zone through an elongated restricting zone and into a tubular reaction zone at a pressure below that of the starch liquid entering the restricting zone, whereby a highly reactive starch liquid emerges from the restricting zone into the tubular reaction zone in the form of a fine spray or mist; and continuously moving the highly reactive starch liquid through the tubular reaction zone to form a homogeneous liquid modified starch product. In the apparatus used the starch slurry feed is held in tank 10 (Fig. 1) and is fed from the outlet 11 to a pump 12 from which it is pumped at high pressure through line 13 to a diverter valve 14 and inlet 16 to reactor 17. The reactor is a closed, insulated vessel filled with heat exchange fluid and the reactor tube 18, 20 and 22 is made up of stainless steel. Coil 18 is the heating zone, coil 20 is the first reaction zone and coil 22 is the second reaction zone. The restriction zones 19 and 21 have the appearance shown in Fig. 2 where 18 and 20 are the tubes previously defined and 30 represents the elongated restriction zone.

Title: Improvements in fluid-pressure actuated controlling means for reciprocable members
IPC: B24B47/06
Filed: 1954-08-16
Abstract: 751,321. Hydraulic control systems. AKTIE-BOLAGET JOHANSSONS PRESS & HEJARVERKTYG. Aug. 16, 1954 [Aug. 19, 1953], No. 23793/54. Class 69 (2). Hydraulic means are provided for controlling the dwell of the table of a grinding machine in either extreme position or in both. A table 1 is actuated by a piston 7 in a cylinder 5, admission and exhaust of liquid from either end of the cylinder being controlled by valves 27c, 27b of a valve unit A. Valve unit A also includes valves 27a, 27d, 27e controlling the operation of a delay valve B. If the table is to dwell in its left hand extreme position but not the right, an auxiliary check valve 89 is opened and a valve 88 closed. In the position shown control valves 27b, 27c and delay valve B establish communication between an inlet 49 and a cylinder chamber 10, and between an outlet 41 and a chamber 8; the piston 7 is thus moved to the left. Towards the end of the stroke a lug 3 on the table contacts a lever L having a pin-and-slot connection with an arm 53 actuating the moving parts of valve unit A. The valve parts are moved slowly restricting the flow between chambers 10, 8 and inlet 49 and outlet 41, and thereby slowing down the table, until a projection 59. moves to the right of a projection 62 of a detent D, whereupon the lever L snaps to its extreme position against a stop 66. Valves 27c, 27b now connect a conduit 26 to the inlet 49, and a conduit 23 to the outlet 41, but the delay valve B remains in the same position and blocks the chambers 8, 10. Liquid is directed through valve 27a to the left hand side of valve B, and exhausted from the right hand side through a conduit 21, a throttle valve C and conduits 76, 52 to the outlet. When the valve B reaches its right hand end position inlet and outlet are connected to chambers 8, 10 of the cylinder. The table is moved to the right until a lug 2 actuates the lever L. Valve A is brought into the position shown in which liquid is admitted through conduits 49, 48, 77, 73, 21 to the right hand side of valve B and exhausted through conduits 19, 38. The valve B is therefore moved rapidly and the table is reversed without a dwell. To obtain a dwell at the right hand end position of the table, but not at the left, valve 89 is closed and valve 88 opened. If it is desired to obtain a dwell at both ends of the stroke a plug 68 of the throttle valve C is rotated to close the connection between conduits 77, 73 so that flow both into and out of the right hand chamber of valve B is throttled. If the table is not required to dwell in either end position a throttle control member 70 is set to allow free passage of liquid through valve C.

Abstract: 904,098. Cable connectors; sleeve couplings. BERNARD WELDING EQUIPMENT CO. July 11, 1960 [July 15, 1959], No. 24087/60. Class 38 (1). An electrical cable connector comprises a tubular malleable metal body member having an integral exterior lug which may be depressed, e.g. by hammering, to produce an indentation in the surrounding metal which grips the end of a cable inserted in the body. Fig. 5 shows a cross-section of a stranded wire cable 28 compressed by indent 30 after lug 27 has been hammered in, the thickness of the cylinder wall 31 being less than the thickness of the sides 26 or of the flat base 25 to ensure that only the top wall of the cylinder part will collapse when lug 27 is hammered. The connector has a tongue 21 with a hole therein for bolting the connector to another component of a circuit. The connector may be cylindrical, in which case it is supported in a saddle block with a flat base during attachment to the wire (Figs. 6, 7, not shown). A connector for joining two separate cables 53, 54 is shown in Fig. 8, consisting of copper tubing 55 having two integral lugs 60, but being otherwise of similar shape to the embodiment of Fig. 5. An insulating member 61 may surround the connector splice and be locked in place by plastic pin 62. The connector similar to that shown in Fig. 5 but without the tongue 21 may be employed for connecting the body member of an arc welding electrode holder to its welding cable (Figs. 12, 13, not shown).
