Title: Toggle operating mechanism for electrical switchgear
IPC: H01H3/30
Filed: 1932-07-12
Abstract: 384,604. Automatic circuit-breakers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and HEATH, A. A., Lydstep, Rowley Park, Stafford. July 12, 1932, No. 19684. [Class 38 (v).] Operating mechanism for a circuit-breaker comprises a setting toggle 14, 15 for locking the closing mechanism after an initial movement of an operating handle 2, and an auxiliary toggle 20, 21 for releasing the setting toggle 14, 15 when tripped, the tripping of the auxiliary toggle 20, 21 releasing an energy-storing device 24, which is adapted to collapse the setting toggle. The operating-rod 5 is biased in the opening direction to the right and is moved to the left after a preliminary clockwise rotation of the handle lever 2 to set the toggle 14, 15. The lever 2 is integral with a rotatable crank disc 3 having a pin-and-slot connection 4, 6 with a triangular plate 7 pivoted at 8. Clockwise rotation of the lever 2 rotates the plate 7 clockwise, thereby rotating a link 12, pivoted to the plate 7 at 13, about a pivot 11 until, nearing the position of Fig. 2, a spring 17 oversets the toggle 14, 15 which is pivoted at 8, 11. The engagement of the pivot 13 with a projection 18 on the link 14 causes the parts, on rotating the handle 2 in an anticlockwise sense, to rotate together and by means of a link 10 to move the rod 5 to the left, the rod being guided by a link 9 also pivoted at 8. Movement of the pivot 38 allows a lever 36, 39 to rotate about its pivot 37 so that the end 39 engages a shoulder 40 on the disc 3 to hold the breaker closed, Fig. 3. During the initial clockwise movement of the plate 7, a pin 31 on a lever 28 pivoted to the plate 7 and to a fixed pivot 30, engages a lever 19 to rotate it about the pivot 8 and compress a spring 24, the parts 19, 24 being held in this position by the oversetting of an auxiliary toggle 20, 21 by a spring 23. The adjustable trip lever 32 is rotatable about its pivot 33 to break the toggle 20, 21 downwards, whereupon the spring 24 rotates the lever 19 so that a pin 35 thereon engages the link 15 to break the toggle 14, 15 and allow the breaker to open. During the opening movement, the pin 38 engages the end 36 of the locking lever to free the disc 3 ready for a further closure. The parts shown are duplicated on either side of a vertical central plane containing the rod 5, and housed in a casing which is apertured to receive shoulders on the discs 3 on which shoulders the discs rotate. The outer ends of the levers 2 are connected bv a horizontal handle part.

Class 75 (2) A vehicle head lamp 3 providing even illumination of a road both at an axial distance 4 and along the sides 5 thereof, has a front glass formed with at least one rib having a cross-sectional profile which continuously decreases in curvature from the portion of said profile intended for the axial illumination of the road to the portion of the profile intended for the illumination of one of the road sides. The profile of the rib cross-section may be part of a logarithmic curve and each rib may comprise a plane portion for half its width to provide for the axially distant illumination. The ribs may be symmetrical to provide for illumination of both road sides or asymmetrical to illuminate one road side only. Fig. 7 shows a ribbed lamp glass, the lower half of which has transversely curved ribs 15 to provide a downward divergence of the beam. The Specification gives formulae whereby the position across the rib of the vertical zone which provides a given deviation of the light rays may be calculated. By calculating these positions across the rib for various deviations and graphically determining the relative slope of the glass surfaces giving the known deviation at each position, the profile of each rib may be determined.

Title: Process for the production of polyvalent alcohols
IPC: C07C31/18
Filed: 1920-07-09
Abstract: Di- or poly-hydric alcohols are obtained by heating the corresponding halogen-hydrocarbons with bicarbonates of the alkalis or alkaline earths under pressure in the presence of water.  Instead of the bicarbonates, mixtures of the bicarbonates and carbonates may be used; catalytic metals such as copper may be added.  According to an example, glycol is obtained by heating and stirring ethylene chloride with aqueous sodium bicarbonate and copper under pressure; the product is worked up by neutralizing with acid and fractional distillation.  In order to prevent undue rise of pressure in the autoclaves, it is advisable to remove therefrom at intervals carbon dioxide and ethylene chloride and lead these to a second vessel. When alkaline-earth bicarbonates are to be used, these are produce in situ from the carbonates by carbonic acid added initially and reliberated during the reaction.

Abstract: 793,198. Radar; transponder apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 9, 1956 [July 12, I955], No. 20188/55. Drawings to Specification. Classes 40 (5) and 40 (7). In an amplitude-modulated C.W. secondary radar system in which.the distance between an airborne interrogation and a ground transponder is derived by phase comparison at the interrogation of the transmitted and received 350 c./s modulation signals, the interrogator and transponder radiate at the same carrier frequency F, e.g. 130 Mc/s, the transmitter and receiver at the interrogation are alternately operative at a switching frequency of 40 c/s. and the transmitter and receiver at the transponder are alternately operative at the same switching frequency such that the transponder receiver is operative when the interrogator is transmitting. In one embodiment, Fig. 1 (not shown), the 350 c/s. modulation signal received at the transponder is detected and applied to synchronize a stable 350 c/s. oscillator by means of a known automatic frequency control system, the oscillator output being applied to modulate a locally generated carrier of frequency F; alternatively, Fig. 2 (not shown), the modulation signal detected at the transponder is delayed for a period of 1/80 secs. by means of a delay line or magnetic recording cylinder and then applied to modulate the carrier. As described, the transponder switching is synchronized with the interrogator switching by deriving at the transponder a 40 c/s. trigger signal from the detected modulation signal and the phase comparison at the transponder is effected by a known form of servo-controlled phase meter. Any one of a plurality of different modulation frequencies may be selected to resolve phase ambiguities. When the transponder includes means for determining the bearing of the interrogator, the bearing data may be transmitted from the transponder as a phase shift on the modulation frequency in response to a special request signal from the interrogator; the difference between the reading of the interrogator phase meter before and after such a request then indicates the required bearing.
