Abstract: 1387001 Aerials SUMITOMO ELECTRIC INDUSTRIES Ltd 5 May 1972 [6 May 1971 21 Feb 1972] 21124/72 Heading H4A A leaky co-axial cable, which may be installed beside a vehicle track, is provided with an array of radiating slots or groups or slots along its outer conductor and has an electromagnetic wave delaying structure associated with its inner conductor. The period of axial spacing of the slots or slot groups p and the shortening ratio v (ratio of waveguide wavelength #g to free space wavelength #) are such that, so as to provide stable leakage wave radiation, i.e., so that, where γ n  is the propagation phase constant in the radial direction of the cable, and n is an integer. The arrangement enables lower frequencies than usual to be employed, for example, of the order of 30 MHz. As described, an inner conductor wire 7, Fig. 3, is spirally wound on an insulating tube 6 and is supported within an outer conductor 9 by insulating means 8. Axially extending slots 10 1 , 10 2 , 10 3 , ... are provided in the outer coductor 9, which has a protective insulating sheath 4. In a second embodiment the inner conductor is of strip form instead of being a wire (Fig. 4, not shown). In a third embodiment, the inner conductor is constituted by a plurality of insulated wires which are wound side-by-side upon an insulating core, and the slots in the outer conductor are inclined to the axis of the cable (Figs. 5, 6, 8, not shown). In a fourth embodiment the slots in the outer conductor of the cable are arranged in groups with a minor constant spacing between the slots of each group and a major constant spacing between groups (Fig. 9, not shown).

Abstract: 970,184. Dispensing articles on conveyers. FINSFRA ENGINEERING CO. Ltd. June 4, 1963 [June 1, 1962], No. 21145/62. Heading A4T. [Also in Division B8] A storage system has tiers of storage bays each provided with a roller track conveyer of which rollers 17 are driven by a belt 11. Each conyer also comprises two spaced roller tracks 14 having support rollers 15. The driving rollers 17 are moved a limited distance vertically when thickened portions 22 of the belt 11 pass between a driving roller 17 and one of a series of mangle rollers 20. The conveyers are arranged to handle pallets 21 which normally rest on the support rollers 15 with the driving rollers in lowered position clear of the underside of the pallets. In Fig. 6(a), at the unloading end of the conveyer a pallet P 1  abuts a fixed stop 25. When the pallet P 1  is removed, a thickened length T 1  of the belt causes a driving roller M 1  to be raised and to rotate, urging a pallet P 2  towards the stop 25, Fig. 6(b). In Fig. 6(d), the belt length T 1  causes a pallet P 3  to be moved towards the stop 25 and a thickened belt length T 2  is about to cause further movement of the pallet P 2  towards the stope 25. As the best continues to run, the lengths T 1 , T 2  engage each driving roller in turn and move each pallet towards the unloading end in two stages. The belt is kept running until the pallet P 2  is against the stop 25 and all the other pallets are end to end behind it. Preferably the belt is then stopped manually or automatically. The belts in each tier are driven through a common shaft by a single motor. To increase the speed of operation of the conveyer a second pair of thickened portions may be provided on the belt.

Title: New or improved means or method for proportionately abstracting from, adding to, regulating the flow of, and measuring fluids in motion
IPC: G05D7/01
Filed: 1921-08-09
Abstract: 191,100. Price, B. Aug. 9, 1921. Fluid - actuated valves for proportionally abstracting from or adding to a primary stream of fluid a secondary stream, or for regulating the flow of a separate secondary stream proportionally to the flow of the primary stream. The primary stream may be measured inferentially by measuring the secondary stream or the secondary stream, when abstracted, may be utilized for analysis, inspection &c. The device for abstracting a secondary stream comprises pipes 3, 10, Fig. 1, leading from a pressure difference creating device in the primary stream to opposite sides of a diaphragm 6 or equivalent carrying a valve 7, controlling a pipe 5, the high-pressure lead 3 being provided with a pressure difference creating device 9. When a secondary stream is to be added, it passes from a graduated tank 12, Fig. II, to the upper side of the diaphragm 6 past the valve 7 and enters the primary stream through the pipe 10 provided with the pressure difference device 9, the high pressure pipe 3 leading to the underside of the diaphragm. When an independent secondary stream is to be regulated, two diaphragms 6 are employed, with their lower sides acted on by the pressures of the primary stream through pipes 3<x>, 10<Y>, Fig. III. The secondary stream passes from a tank 12 or pump through a pipe 19, past a, valve 7, through a pipe 10<x> with a device 9, and past a second valve 7 into the outlet pipe 5. By connecting the pipe 19 to the upstream side of the primary stream, this device also may be used for proportional abstraction. By inverting the device and connecting the pipe 5 to the downstream side of the primary stream, a proportional addition may be made. A constructional form corresponding to the diagrammatic form of Fig. I is shown in Fig. IV. A diaphragm 23 corresponding to the diaphragm 6 and balanced by weighted arms 29 carries a universally mounted telescopic spindle 66 on which is a valve 38 working in a. conical seating in a weighted diaphragm 24, which supports a valve 43 working in a conical outlet 44. In a constructional form corresponding to the diagrammatic form of Fig. III, the diaphragms are weighted, and the pressure difference creating device in the secondary stream consists of an orifice in a plug cock, the body of the cock having holes for cleansing the orifice when the plug is turned so as to close the secondary circuit.

Title: Improvements in Autographic Registers.
Inventor: THOMPSON WILLIAM PHILLIPS
IPC: B41L5/06
Filed: 1918-12-19
Abstract: 136,642. Thompson, W. P., (Business Systems, Ltd.). Dec. 19, 1918. Memorandum appliances; carbon papers, arrangements of.-An autographic register, in which a number of superposed webs of paper containing printed forms, such as sales slips, are fed over a writing-table, is provided with alining-pins for periodic engagement with perforations in the webs to register the superposed forms at the cornpletion of each recording and feeding operation. When the alining-pins enter the register openings in the webs, they cause the feeding-mechanism to release its hold upon the webs and allow these to be drawn backwards into register. The carbonroll support is constructed to hold rolls of various widths. The superposed webs and the carbon paper are supported between a writing-table 5 and a frame 60 both mounted on pivots 6, the webs being fed under the alining-pins 110 and between the feeding-rolls 80, 90. The lower feed-roller 90 is mounted on spring-controlled pivoted plates 91 operated by arms 100, 98 mounted on a spindle 97, to lower the roller 90 out of action. As long as the alining-pins rest on the webs, they act through cranks and cams on a spindle 115 to keep the arms 100, 98 out of action; but, when the alining-pins drop into the register openings in the webs, the spindle 115 is allowed to turn under the action of springs and to turn a cam 165. This action allows a frame 170 pivoted to a spring- pressed detent arm 102 to descend and bring the detent into gear with teeth 83 on the feed-roller 80. This operates the arm 100 to release the feed-roller 90 and then lock the feed-mechanism in its inoperative position. The webs are then drawn back by the natural spring of the paper or by the downward motion of the guide-rolls 20 in slots 16. The spindle 115 is operated by a handoperated arm to release the detent from the teeth 83 and allow the feed-roll 90 to rise into operative position again, and to raise the alining-pins and hold them raised by means of a.notched locking- collar 130. The initial motion of the feed-roller 80, which is operated by a handle, operates through gearing to release the locking-collar 130 and allow the alining-pins to drop on to the webs just in the rear of the register openings. A disk 45 is held in the required position on the carbonroll support 40 to suit the width of the carbon paper.
