Title: Improvements in or relating to measuring instruments
IPC: G01R11/56
Filed: 1939-04-28
Abstract: 528,518. Counting-apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 28, 1939, No. 12809. Convention date, April 29, 1938. [Class 106 (i)] [Also in Group XXXVI] The output and duration of energy between each two of a number of arbitrary load ranges of a varying quantity is measured by a subtraction method. A shaft I, Fig. 3, is driven by ratchet gear Ea from an electricity meter Im and has fixed on it sun-wheels V1-Vn. Sunwheels H1-Hn are rotatably mounted on the shaft I and are driven by gearing E1-En from a constant-speed shaft P1 which is driven by a clock or synchronous motor M. The gearing E1-En is so arranged that the sunwheels H1-Hn are driven at progressively increasing speeds corresponding to the different load limits E1-En, Fig. 1. Differential wheels D1-Dn are driven by the sun-wheels at speeds proportional to the difference between the actual load and the different load limits E1-En and may drive unidirectional counters indicating the energy consumed above these limits. Alternatively they may drive the sun-wheels of differential gears S1-Sn-1 mounted rotatably on a shaft P3, alternate differential wheels being provided with an intermediate pinion U so that the sun-wheels of the differential gears S1-Sn-1 rotate in opposite directions. The differential wheels of these gears consequently rotate at speeds proportional to the difference of the speeds of adjacent differential wheels D1-Dn and drive, through unidirectional gearing, counters Kwh, H indicating the energy consumed between adjacent load limits. In order to measure the duration at the several load limits, each of the differential wheels D1-Dn closes a snap-action switch when the planet pinion moves in a positive direction and opens it when the rotation is negative. This switch controls a circuit to a synchronous clock, and may be used for signalling and controlling purposes.

Title: Improvements in or relating to short-wave aerial systems
IPC: H01Q13/10
Filed: 1947-05-16
Abstract: 637,113. Aerials. PHILIPS LAMPS, Ltd. May 16, 1947, No. 13209. Convention date, May 21, 1946. [Class 40 (vii)] In a short-wave aerial system comprising two radiators arranged parallel to one another with the distance between them small compared to their length and with corresponding ends short-circuited, the aerial structure exhibits the form of a single rod, tube or plate in which one or more longitudinal slits are provided. In one embodiment, Fig. 2, an aerial of this " folded dipole " 'type is formed by a metal tube with longitudinal slits in either side so that two radiators AB and CD are provided separated by a distance which is small relative to their length. The radiator CD is interrupted in order to permit connection of a feeder V. The frequency bandwidth for which the aerial system is suitable can be adjusted by making the slits longer or shorter, thereby varying the distance at the ends over which the short-circuit extends. By providing the slits on a chord instead of a diameter the thickness of the fed radiator with respect to the other radiator can be varied and thus increases or decreases the aerial characteristic impedance. The aerial may alternatively be formed from a solid rod by providing only one longitudinal slit, or from two U-bars with their open sides turned towards one another and their corresponding ends welded together, Fig. 3 (not shown), or from one U-bar and a flat plate, Fig. 4 (not shown).

Title: Regulating electric quantities in current converters
IPC: H02M7/15
Filed: 1937-05-11
Abstract: 479,990. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 11, 1937, No. 13375. Convention date, May 12, 1936. [Class 38 (ii)] In a converting arrangement in which the grid control is varied in dependence on the difference between a regulating current and a standard current the regulating current consists of two components, one a current representing the quantity to be regulated and the other a current representing the rate of change of the quantity. In an arrangement for regulating the voltage of the D.C. circuit of a rectifier 1, Fig. 1, a regulating current obtained from the D.C. circuit is compared with a standard current at the point 5 and the difference current controls a phase shifting impedence 2 in the grid circuit. The component of the regulating current proportional to the voltage is obtained by means of a resistance 4 and the component proportional to the rate of change of voltage by means of a condenser 6. In a modification of this the condenser 6 may be connected across the D.C. circuit through a transformer and resistance the secondary of the transformer being connected to the points 5. If the transformer has a large magnetizing current the condenser may be omitted. In a further modification, Fig. 3, for regulating the current of a rectifier 1, the component proportional to the current is obtained from a current transformer 9 and rectifier 10, and the component proportional to the rate of change of current is obtained from a current transformer 11 in the D.C. circuit. The primary of this transformer may be the smoothing choke in the D.C. circuit. A harmonic filter circuit 12, 13 may be provided. Specification 459,443 is referred to.

Abstract: 864,630. Woodworking. WST PATENTER A.B. April 20, 1959 [April 22, 1958], No. 13460/59. Class 145. In a machine in which a tool 2 is guided to cut a recess 13 in a workpiece 14 by a guide roller 8 moving in a recess 15 in a templet 9, a second templet 10 having a recess 17 smaller than the recess 15 is displaceably secured to the templet 9 and, when the guide roller reaches direction-changing points, the roller moves the second templet to actuate limit switches 6, 6a, the switches controlling magnetic valves for the air supply to rams 4 and 5 by which a support 3 carrying the tool and roller is movable in two mutually-perpendicular directions. The second templet is pressed against the templet 9 by spring holders 16 and is adjustable in two directions by eccentric pins 12. In rest position, the ram 4 is acting upwards and the ram 5 towards the right. When the current is switched on, an impulse is given through the switch 6 to supply air to move the ram piston and support 3 to the left. When position II is reached, the second templet 10 is moved to the left as far as permitted by the templet 9 and the switch 6 is actuated so that ram 5 moves the support to the right and current is supplied to the switch 6a to 'cause the ram 4 to tend to pull the support downward. The downward movement is prevented by the roller 8, in the narrow portion of the recess 17, until the roller can move down the broader portion of the recess to position III where it continues to the right until, in position IV, it moves the second templet to the right. The switch 6 is then released, the current switched off and the roller 8 returned upwards by the ram 4 to its original position.

Abstract: 1409995 Spinning viscose SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA SpA 27 March 1974 [6 April 1973] 13648/74 Heading B5B [Also in Division Dl] Viscose filaments, spun from spinneret 10 into coagulating bath 12 are stretched, treated, washed and dried in a unitary assembly enclosed for the protection of operators in chamber 46. The filaments are stretched in stretching tube 14 and then passed around treatment roller 18 and auxiliary rollers 28. Roller 18 is divided into zones 18a by flanges 20. The filaments are exposed to the action of various treating and washing liquors in the zones 18a by spraying, preferably, or by pouring the liquors on to the filaments. Used liquors are collected in tank 22 separated into zones 22a and conducted away via conduits 26. Individual filaments 30a-30d are passed around the rollers 28a-28d in that order and are then transferred by a suitable means to the next treatment zone after washing. After each treatment, the filaments are washed free of the reagent. However, in order to prevent progressive contamination of the washing liquors, the treating reagents may be partially removed before washing. This may be accomplished, as in Fig. 5 by gas jets 56, playing upon the filaments, or as in Fig. 6 by passing the filaments through a device having an elongated body 60, chambers 62 and 66 connected to gas conduits 68 and 70. The gas supplied to this device is previously dried and preferably heated. After treatment the filaments are dried, either, as in Fig. 1, by passing around the terminal zone 18a which is heated, or as in Fig. 4 (not shown) by passing the filaments through a heated drying tube.
