Title: Improvements in or in connection with variable electric condensers
IPC: H01G5/06
Filed: 1925-06-13
Abstract: 257,367. Rickets, W. J. June 13, 1925. Condensers of the type in which the capacity change is substantially proportional to the square of the angle moved through by the moving system of vanes, comprise a vane or vanes A rotatable about an axis x and a fixed vane or vanes B, the outer edge of vane A being circular with its axis at x, while the inner edge a<1> is made concave and preferably of two similar curves meeting on a radius r<1>. The relation between the radius r of the curve, the fixed radius R of the outer edge, and the angle # measured from one of the lips of 'the vane is stated to be r<2>=R<2>-4K#, where K is a constant. The fixed vane may have an outer edge of any contour but its inner edge is preferably configural with that of the plate A, so providing a very low minimum capacity. The vane A is carried on its spindle by an arm E lying entirely to one side of one of the curves a<1> so as not to effect the capacity. To allow for effects of self-capacity of one of a series of plug-in coils C constituting with the condenser an oscillating circuit, the coil is shunted by a small fixed, or vernier variable, condenser so as to bring the aggregate of the capacities up to a predetermined initial value. In such a case the crescent tips a<3> are cut off to reduce the capacity of that condenser by an amount equal to the external capacities.

Abstract: 938,379. Drag line scrapers. LONG MEG PLASTER & MINERAL CO. Ltd. June 22, 1960 [May 9, 1959; May 2, 1960], Nos. 15975/59 and 15327/60. Class 68 (1). [Also in Group XXX] A vehicle 31, Fig. 1A, is loaded by a skip 20 which draws material up a tailboard 25. An hydraulically operated telescopic boom 15, 16 is slewed by an hydraulic ram 19 and luffed by rams 17, 18, the tailboard being raised and lowered by a ram 27. In a second embodiment the boom is pivoted to a vertical post mounted at a forward corner of the trailer by an obliquely disposed hydraulic ram which simultaneously slews and luffs the boom. In both these embodiments the trailer is unloaded into a hopper by hydraulic rams which push rearwardly inner side and rear walls 26, 30. Since the tailboard is attached to the inner walls and moves back therewith, thus disengaging the ram 27, guides 86, Fig. 6A, are provided to hold the tailboard up whilst the material is discharged. Ropes 21, 23 are wound on to winches driven by an hydraulic motor or by the power take-off of the tractor. Alternatively hydraulic rams and pulleys may be employed. In an alternative construction two telescopic arms arranged alongside the trailer body may be joined by a cross-bar along which a pulley similar to the pulley 10 is traversed hydraulically. In a further embodiment, Fig. 1, a skip 122 is suspended from two telescopic booms 104, 105, Fig. 2, joined by booms 110, 111. The booms 104, 105 can be telescoped individually and are tilted about pivots 108, Fig. 1, by rams 130. A tailboard 120 is operated by a ram 134. Rams 139 move the inner side walls 137, 138, Fig. 2, and the end wall 136, with respect to the outer walls, to unload the trailer into a hopper situated below it. Power for the rams may be drawn from a tractor pulling the trailer or from a separate pump mounted on the trailer, the latter being driven either by a separate motor or by the power take-off of the tractor. Winches 124, 126, Fig. 1, are driven from the power take-off or by a separate hydraulic motor. The boom comprises a cylindrical housing 106, Fig. 4, closed at one end by a plate 151 and having four wheels 152 at the opposite end which co-operate with the corners of a square section inner telescopic member 104, Fig. 7. The latter has four wheels 161 which guide its inner end by co-operating with four strips 153, Fig. 4, of angle section within the tube 106. The boom is extended by an internal hydraulic ram. The tailboard of the trailer may be raised by a cam attached thereto which is moved by a pin on the inner side wall of the trailer, the wall being moved rearwardly through a small distance to lower the tailboard and to the forward position to raise it. Specification 938,380 is referred to.

Patent GB-998850-A (GB)
Title: Air conditioning system
IPC: F24F11/08
Filed: 1962-04-26
Abstract: 998,850. Control systems for air-conditioning apparatus. SINGER CO. April 26, 1962 [April 26, 1961], No. 15993/62. Heading H2H. An air-conditioning system for maintaining various zones of a building at individually selected temperatures comprises a plurality of separate air-conditioning units, a central control switch common to all the units and an individual switch assembly associated with each unit to allow the units to be controlled either as a whole or individually, the central control switch being momentarily opened periodically to de-energize all the units after which each unit can be re-energized by means of an associated manually-operated switch. With the switches 34 in each of the rooms 2, 4, 6 closed, closure of the main switch 12 will initially energize the heaters 52 of the bimetal switches 42 which are arranged to have different operating characteristics. As the bimetal strips 50 are heated so as to move to the right (as shown), contacts 54, 56 first close and then open. When closed, these contacts cause energization of the coils 40 of relays 46, closing self-maintaining contact 41 and a further contact 43 which completes the circuit for the compressor 14 and fans 24, 28 of the air-conditioning units. Should any unit not be required, its operation can be terminated by opening the associated switch 34. In order to prevent operation of the air-conditioning units when rooms are unoccupied the main switch 12 is arranged periodically to be opened and immediately reclosed automatically by means of a motor 138 and cam-operated switches 126, 128. Opening of the main switch 12 de-energizes relays 46, thus removing the supply from the air-conditioning units. The immediate reclosure of switch 12 does not re-energize relays 46 since bi-metal switches 42 remain heated and in the right-hand position. Should any room now be occupied the associated air-conditioning unit can be restarted by closure of switch 44 to energize relay 46. The system is shut down by opening switch 12. The switch 12 may be manually-operated by means of switches 125, 127 and the switches 42 are given random operating characteristics so as to prevent heavy starting current.

Title: Cross wound cops of artificial silk and device for winding same
IPC: D01H1/00
Filed: 1930-05-26
Abstract: 357,606. Winding cops of artificial silk. PERCIVAL, S., 40, Chancery Lane, London.-(Barmer Maschinenfabrik Akt.- Ges. ; Wuppertal, Oberbarmen, Germany.) May 26, 1930, No. 16172. [Classes 120 (ii) and 120 (iii).] Artificial silk is wound into cops which are preferably at least three inches in diameter, the individual layers having an inclination of at least 15‹, and consist of superimposed groups of layers, each group being formed by displacing the layers relatively to each other, first in an upward and then in a downward direction. A completed cop is shown in Fig. 6, a, l indicating the first and last layers of the first group, which is formed by displacing the guide rail upwardly to wind the layers a .. f, and downwardly to wind the layers g .. 1, and then imparting an additional upward displacement to wind the next group. The method of winding facilitates dyeing and subsequent unwinding. The cops 6 are preferably wound during doubling and twisting in a machine as shown in Fig. 1. The traverse is effected by a belt 21, Fig. 4, on a pulley 32 oscillated by a belt 30 connected to a disc 29 carried by a frame 27 coupled to a frame 26 which is oscillated by a traverse cam 22. The frames 26, 27 are coupled by a cam 39 the rotation of which causes upward and downward displacement of the layers of each group. The lift to displace each group is effected by the rotation of the disc 29, by means of ratchet gearing, which is only operative when the cam 39 has so displaced the frame 27 relatively to the frame 26 and the winding of a group of layers is completed that the arm which carries the ratchet pawl 36 strikes the stop 37. The disc 29 is formed with a decreasing effective radius so as to form closer winding towards the nose of the cop. The delivery spindle 1 is driven by a belt 5 and drives the winding-spindle by a belt 13 which actuates a pulley 15 connected to the delivery rollers 14 by worm gearing.
