Title: Improvements in and relating to electrical remote control systems employing frequency responsive relays
IPC: H02J13/00
Filed: 1940-12-23
Abstract: 543,794. Electromagnetic relays PRICE, D. R. and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 23, 1940, No. 18019. [Class 38 (v)] A frequency responsive relay, adapted to respond satisfactorily to ripples of widely varying amplitude superimposed on a power line'has two operating coils 8, 9 acting upon a reed or the like in opposition to each other and the coil 8 which overpowers the coil 9 has in series with it a resistance such as a metal filament lamp 13 with a positive resistance-voltage characteristic. Thus as the amplitude of the ripple increases, the resistances of the lamp 13 will increase and ampere turns of the coil 8 will increase less rapidly than the ampere turns of the coil 9, and the resultant effect on the tuned reed will not be unduly great. The relay is adapted in the circuit arrangement shown, to be energized by means of a transformer 10, 11, the primary 11 of which is energized from the terminals 5, 6. A resistance 15 with a negative characteristic may be connected across the primary winding 11. Specification 517,971 is referred to.

Patent GB-673979-A (GB)
Title: Improvements in thread carrier driving mechanism for straight bar knitting machines
IPC: D04B15/54
Filed: 1949-07-08
Abstract: 673,979. Knitting. COLTON, L. H. (Thiede, W.). July 8, 1949, No. 18043/49. Class 74 (ii). A straight-bar knitting-machine has a positive thread carrier drive, providing a substantially constant lead of the thread carrier or carriers in front of the slurcock, in which a coupling device for engaging and disengaging a thread carrier rod to and from the slurcock bar comprises an element movable along a cycloidal path during engagement to achieve substantially shock-free acceleration of the thread carrier rod at the commencement of its travel and movable along a cycloidal path during disengagement to achieve substantially shock-free retardation of the thread carrier rod at the end of its travel. As slur bar 1 begins to move to the left, pinion 7, which is carried with it, rolls along rack 15 and is rotated clockwise through 90 degrees. During this rotation, roller 6 enters behind member 9 and moves thread carrier rod 2 with increasing speed until, when crank-arm 5 is horizontal, bar 2 is moving at the same speed as bar 1. Towards the end of the traverse, pinion 7 engages rack 16 and is rotated through a further 90 degrees to release member 9 by means of a bar 24. Rack pairs 15-17 and 16-18 are now raised whilst the slurcock is stationary, so that, as the reverse traverse begins, pinion 7 rolls along rack 18 through a third 90 degrees to enter pin 6 behind member 11 and accelerate rod 2 up to full speed and, as the traverse is ending, rolls along rack 17, through a final 90 degrees to disengage pin 6. Racks 15, 17 and 16, 18 are moved, during widening or narrowing, by means of rods 26, 27.

Title: Improvements in isolating electric switches
IPC: H01H21/06
Filed: 1940-12-23
Abstract: 542,863. Switch covers. ELECTRICAL APPARATUS CO., Ltd., and WALTON, J. R. Dec. 23, 1940, No. 18065. [Class 38 (v)] An isolating switch has a casing 10 for attachment to an enclosure for electrical apparatus, such as a motor starter, part 43 of the cover 39 of the enclosure disengaging a catch 48 holding the external operating lever 17 in the open position, and a part 40 of the same coverco-operating with a locking element 44 on the lever 17 to prevent removal of the cover 39 when the isolating switch is " on." In the example, a flange 45 on the lever 17 has a gap 49 into which a spring-pressed element 46 fits when the cover 39 is removed. On replacing the cover, the plate 43 forces back the catch to the position shown in Fig. 4. The operating lever can now be moved, the flange 45 riding on the sloped edges 48, of the catch. When the switch is " on," the projection 44 on the flange enters a slot in the channel 40 on the cover, thus preventing removal of the cover along its dowel fixings 76. The switch shown has a contact bearing block 28 adapted to be slidden backwards, on rotation of the handle 17 and spindle 19 attached thereto by the action of the ends of a pin 24 working in a cam groove 25 in a sleeve 26. Contact strips 32 are thereby pressed against the fixed contacts 15, 35 to bridge them. A swinging latch 50 pivoted in a bracket 51 has an arm 57 which, when the cover 11 of the isolating switch is in position, is deflected by a ramp 55 inside the boss 20 to hold the latch clear of a groove in the sleeve 26. On removing the cover the latch prevents the sleeve 26, and hence the contacts, being moved from the " off " position.

Patent GB-1080462-A (GB)
Title: Improved production of olefin oxides
Inventor: BLJUMBERG ANNA ALJBERTOVNA
Filed: 1964-07-04
Abstract: Olefin oxides are prepared from the corresponding olefins by contacting in the liquid phase a mixture of the olefin and a further organic compound, which is more readily oxidized than the olefin and which is not the saturated hydrocarbon corresponding to the olefin, with molecular oxygen, the further organic compound being oxidized to an intermediate organic peroxy compound which reacts with the olefin to form the olefin oxide. In addition to the olefin oxide other oxygenated compounds such as acids, ketones, alcohols, esters and peroxy compounds may be produced and separated.  The further organic compounds may be, for example, hydrocarbons such as n-butane, light gasoline, ethyl benzene or isopropyl benzene; or carbonyl compounds such as acetaldehyde, propionic aldehyde, benzaldehyde or methyl ethyl ketone.  The process may be carried out at temperatures in the range 60-200 DEG  C. depending on the nature of the further organic compound and pressures of 1-100 atm.  An inert solvent, for example benzene, may be used and the concentration of explosive hydroperoxides may be controlled by carrying out the process in the presence of an initiator of peroxy compound decomposition, e.g. a transition metal compound such as cobalt acetate.  Reference has been directed by the Comptroller to the Specification 963,430.
