Abstract: 1,136,712. Moulding tyres. NAUCHNOISSLEDOVATELSKY INSTITUT SHINNOI PROMYSHLENNOSTI, and VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT REZINOTEKHNICHESKOGO MASHINOSTROENIA. 5 Jan., 1966, No. 454/66. Heading B4A. A tyre-moulding plant has two similar lines of equipment, each comprising a stationary device B at which moulded tyres are removed from moulds A and fresh ones supplied, and heated fluid is fed into the moulds, a stationary, tunnel-like vulcanizer C through which the moulds pass, and a stationary device D for draining the heated fluid and cooling the vulcanized tyres. The moulds are arranged in pairs, and are conveyed on a carriage 26 on rails by pushers 101 along one line of equipment, and then transferred from a heated fluid-draining device D by a carriage F mounted on rails 79 to the other line. Pushers 86 transfer the moulds from the carriage F to a device B. The vulcanized tyres are carried from the device B to a conveyer 105 by conveyers 103, 104. Each mould comprises mould halves 1, 2 interconnected by bayonet locking devices 3, 4, and including a bag or diaphragm 14 into which heating and cooling fluid is supplied via a valve 18. When a pair of moulds reaches the device B they are lowered so that their lower locking devices 4 can be unlocked by power cylinders 42. The upper bayonet connections 3 are unlocked by keys carried by members 34 supported on a transverse member 31 which is . lowered to bring the keys into contact with the mould parts, whereupon power cylinders 37 rotate the keys. During such unlocking, the upper mould parts are engaged by further keys which are extended into those parts by a power cylinder 41 on the member 31. When the mould halves are disconnected the member 31 is raised, the bag distended by a power cylinder 58 and member 57 whereby the tyres can be removed by means of an arcuate arm 66 which is vertically reciprocable and pivotal about a vertical axis. Fresh tyres are then supplied to the moulds by holders 61 which are similarly supported; the member 31 is lowered and the bags supplied with steam and hot water via pipes 54 and the mould halves interconnected. After releasing the member 31, the moulds are raised and driven through the vulcanizer C by pushers 101, with the hot water contained therewithin. They are then received on a table of the cooling and draining device D which has a vertically extending part which opens the valves 18 and supplies the bags with cold water before finally draining them. The moulds are then conveyed to the second line of equipment where the vulcanized tyres are removed by the device B and fresh unvulcanized ones supplied.

Title: Detection of atmospheric activity
IPC: G01R29/08
Filed: 1976-01-09
Abstract: 1529624 Detecting atmospheric electrical activity DYTRONICS CO Inc 9 Jan 1976 [10 Jan 1975] 00864/76 Heading H4D A system for mapping electrical storms receives electromagnetic signals in a predetermined frequency band from electrical activity in a storm, processes the received signals to give further signals of amplitude inversely related to that of the received signals, and uses the processed signals to drive a display. Thus received signals of high amplitude are represented in the display further from the display origin than are received signals of low amplitude. Assuming that the electromagnetic signals are of uniform strength at their source, the processing accounts for their attenuation with range from the receiver and the display will represent such range. In the Fig. 4A embodiment, electric and magnetic components of the e-m signals from lightning are detected by antenna 10 and crossed loop antennae 11, 12 respectively. Signals from the loop antennae are "correlated" at 16, 17 with the antenna 10 signal to discriminate against noise. Signals Ex, Ey, representing the magnetic field strength components in orthogonal directions, are obtained by integration at 18,19 over periods set by timers 20 in response to the sum of the signals from 11, 12 exceeding a threshold value set at 22. The thresholding serves to distinguish signals due to main lightning strokes from unwanted signals due to preceding leader strokes. In "foldback" unit 24 the signals Ex, Ey are effectively divided by E R <SP>2</SP>, the square of the sum of the signals from 11,12, to give the processed signals which, after storage in recirculating shift register memories 26, control the deflections of a CRT display 28 to produce a display spot at a position corresponding to the azimuth and approximate range of the the lightning discharge. If the system is to be used on an aircraft, motion of the aircraft will make the display inaccurate due to the changing range. To overcome this, old data are erased from memories 26 if they are not being up-dated fast enough by successive lightning discharges; alternatively the memory contents may be decremented, at a rate chosen with regard to the speed of the aircraft, so that the display "creeps" in one dimension to compensate for the motion. The foldback processing may be analogue (e.g. optical) or digital. Details are given of digital foldback processing (Figs. 8A and 8B, not shown) and of circuits for the motion compensation (Figs. 10A-10F, not shown). The memory and display functions may be combined, e.g. by using a storage tube, LED or liquid crystal display.
