Title: Method for erecting tower-like structures
Inventor: KOGA TARO
IPC: E04H12/34
Filed: 1970-12-18
Abstract: 1282240 Method of erecting towers; jacks MITSUBISHI JUKOGYO KK 18 Dec 1970 60340/70 Headings B8B and B8J A method of erecting a tower or like structure 1, comprises laying the assembled tower on the ground 6 and coupling the lower end thereof to an horizontal pivot 3 on the tower foundation 4, coupling an hydraulic jack means 8 to each of two opposite sides of the tower, each of which jack means is movable along a beam 5 pivoted at 7 to the ground, and moving the jack means along the beams to pivot the tower into the erected position. Each beam 5 includes a pair of opposed racks extending longitudinally thereof and which are engageable by pins of a piston operated clamp at the free end of the jack piston rod and at the closed end of the jack cylinder, the clamps being operated alternately to form a reaction point for movement of the jack along the beam, the jack being double acting. Alternatively, a screw jack may be used. In the embodiment of Figs. 5 and 6 (not shown) the jacks are pivotally attached to the lower end of the tower on the opposite side to its connection to the foundation, the lower ends of the beams being pivoted to the foundation. In the embodiment of Figs. 7-8 (not shown) a base portion of the tower is mounted in position on the foundation and the jacks are pivotally secured to the top end of this portion, the beams having their pivoted connection on the base part of the main portion of the tower. In the embodiment of Figs. 9 and 10 (not shown) the movable beams are pivoted to the ground adjacent the top end of the tower as it lays on the ground, and after partially raising the tower, it is supported on a temporary strut while the beam and jack are moved nearer the pivot of the tower, whereby the tower is further raised, this procedure being repeated until the tower is fully erected. In the embodiment of Fig. 11 (not shown) the tower is partially erected as in the embodiment of Fig. 1, and the tower is then supported on a temporary strut while the beam and jack are moved for connection to the tower at the other side of its ground pivot. In the embodiments of Figs. 12, 13, 14 (not shown) the tower is erected as in the embodiment of Fig. 1, but additionally, the upper side of the tower as it lays horizontal, is pre-tensioned by a winch and cable arrangement, to offset bending stresses in the tower during erection. In the final embodiment of Fig. 15 (not shown) the tower is erected in steps by repositioning the beams and jacks closer to the tower pivot as the tower is raised, and wherein the bottom side of the tower adjacent the ground is pre-tensioned with a cable and winch while the jack is at its furthest point from the tower pivot, and the top side of the tower is thereafter pre-tensioned for the rest of the erection.

Title: Hydraulic control circuits
IPC: F15B11/17
Filed: 1971-12-29
Abstract: 1381870 Hydraulic systems COMMERCIAL SHEARING & STAMPING CO 29 Dec 1971 [11 Jan 1971] 60608/71 Heading F1P An hydraulic system comprises a first group of directional control valves 13, 14, 15 for hydraulic motors (not shown), a second group of directional motor control valves 16, 17, 18, two supply pumps 10, 11 for supplying fluid to the valves, and a line 85, 86 connected between the pumps and having branch connections 38 leading to the valves 16, 17, 18, the connections being disposed on opposite sides of a pair of parallel connected normally open spool valves 81, 82 provided in the line 85, 86. The spool valves 81, 82 are closed in response to the simultaneous operation of at least one directional valve on each side of the spool valves, whereby each directional valve 16, 17, 18 receives fluid from one pump instead of both pumps. When a directional valve 16, 17 or 18 is operated it causes pressurization of one or other of signal lines 89, 90 to cause closure of the spool valve 81 or 82. With only one of the spool valves 81, 82 closed, a flow-path 87 or 88 still exists to the operated directional valve or valves from both of the pumps 10, 11. Each time any of the valves 16, 17 or 18 is activated a pressure signal is sent through a passage 89, 112 and/or a passage 90, 122 to a signal block 100 containing shuttle valves 96, 97 and spool valves 103, 104. The block 100 is operative to transmit the signal or signals through passages 93 and 93a to a compensating valve 21 and/or a compensating valve 22, each compensating valve being responsive to the signal received, to regulate the flow and pressure output of its pump. The construction and operation of the compensating valves and the directional valves are also described in Specification 1293550. When a single directional valve is operated the signal block 100 sends the same signal through passages 93, 93a to both compensating valves, whereas if, say, valves 16 and 17 are operated, the block 100 transmits a separate signal from valve 16 to compensator valve 21 and a separate signal from valve 17 to compensator valve 22.

The web may be used to form tetrahedron or parallelepipedic containers and may comprise a laminate of one or more layers of paper laminated on one side to layers of polyethylene or polypropylene and having on the other side a layer of wet strength paper, and/or a layer of wax or polyethylene. The paper layer(s) may be replaced by a layer of foam polystyrene covered on one or both sides by a layer of polystyrene. The web may include a metal foil layer. A web 10 is fed through a supply chamber 30, and tension control 32 to a chamber 34 where a set length of the web accumulates. Rollers 245, 260 then pull the set length successively through a punch chamber 36 and a tab heat seal chamber 38. The web passes into a collection chamber 42 before being wound into the roll 46. Photocells 62, 66 in the chambers 30 and 42 control the speed of rollers 22, 24 and 44, 45 feeding the web into and out of, respectively the two chambers. In the chamber 34 with an exit clamp 74 closed, accumulators 76, 77 are moved downwardly by cam actuated rods and a roller 100 moved downwardly by a cylinder 78. When the accumulators 76 and the roller 100 have completed their movement and a photo-cell 50 has detected indicia on the web the entry clamp 72 closes and the cylinder 78 retracts, the final movement of accumulator 77 taking up the stack in the web. The roller 245 is alternately pressed against driven roller 260 to pull the web out of the chamber 34 and against driven roller 240 to maintain its rotational speed. The punch chamber 36 comprises two rows of staggered rods 128 which are reciprocated by a cam 130 to punch holes in the web when it is stationary. In chamber 38 heated platens 152 reciprocated by arms 155 (Fig. 14) press a tab over each opening, the tabs being cut by blades 162 from tapes 164 fed by rollers 168 intermittently rotated by a ratchet. Each tape is supplied from a roll in a bin and is passed over a stop motion wire which is actuated by the tape pulling the core tube of the roll against it on exhaustion of the roll. The tape then pasess over pull back preventer 172 to eccentrically mounted rollers 176, 178 which are moved upwardly by the arm 155 to supply tape to roller 168 just before it is rotated. A photo-cell 70 detects the absence of a tab over an opening.

Title: Digital-to-analog converter
IPC: H03M1/00
Filed: 1979-08-22
Abstract: A digital-to-analog converter which can be used as an interpolative decoder for decoding a linear PCM signal includes registers (201, 202), a binary rate multiplier (203), driver circuits (31 to 38) and a ladder resistance network (400). An output signal of the binary rate multiplier (203) which develops e.g. the four least significant bits of the linear PCM signal onto a time axis is directly applied to the driver circuit (38), to drive the segment of the ladder resistance network (400) corresponding to the least significant bit, the ladder resistance network having segments corresponding to signals of e.g. the eight most significant bits of the linear PCM signal. Thus, the need to use an adder for the digital addition between the output signal of the binary rate multiplier and the signals of the several more-significant bits is avoided. <IMAGE>

Title: Railroad interlocking signal system with insulated joint failure and overrun protection
IPC: B61L1/20
Filed: 1979-11-14
Abstract: Insulated joint failure detectors are placed at each controlled signal location in the railroad interlocking to detect the condition of the track circuit insulated joints and also the passage of each truck of a train moving in either direction past that location. Contacts individually responsive to detector operation serially control the lockout of cab signal transmitters to inhibit the transmission of cab signal commands within the interlocking if an insulated joint fails or an unauthorized train overruns a controlled signal. These detector contacts are individually bypassed by parallel circuit paths, controlled either by the corresponding home signal relay or cab signal control relays properly energized along an established route, in order to prevent lockout when the train is authorized to pass that signal location. <IMAGE>

Title: Radar Display Apparatus
IPC: G01S13/538
Filed: 1980-11-19
Abstract: Radar display apparatus employs digital techniques to convert range/azimuth scan to TV scan. A digital store contains data for each picture cell of a TV display. The store is continuously up-dated in accordance with received video. A control circuit for up-dating the contents of the store can operate in a selected one of a number of different modes. In one mode the analogue video is digitised in a one-bit digitiser and the digitised video stored in a fast buffer. The digitised video from the fast buffer is supplied to a four-bit adder which is arranged to add the relevant video bit to the existing contents of each cell location of the store in turn so that the contents of each cell location represents the degree of positive correlation of video signals in successive azimuth scans of the radar. In a second mode, the analogue video is again fed to the digitiser and buffer. However, in this mode, the adder operates to compare the received video bit for each cell of the store with the corresponding video of that cell in the preceding azimuth scan. The memory is loaded to indicate a target for display at a particular cell in response to a received video bit only if there was no display bit in that cell on the preceding azimuth scan. This provides area MTI. In a third mode of operation, the analogue video is digitised in a four-bit digitiser and a four-bit digital video fed directly into the memory so that the contents of the memory represent the signal strength of the received video.
