Title: Improvements in or relating to air speed indicators
IPC: G01P5/16
Filed: 1941-12-19
Abstract: 554,410. Air speed indicators. HAMSHERE, E. A. Dec. 19, 1941, No. 16411. [Class 106 (ii)] An instrument automatically corrected for altitude changes comprises a rock shaft actuated by a metal capsule responsive to variations in pitotstatic pressure, a second rock-shaft mechanically coupled to the indicator pointer oppositely projecting lever arms carried by the rock shafts, and variable coupling means between the lever arms actuated by means responsive to changes in the static pressure. The pressure fluid from a pitot tube is transmitted through the pipe 2 to a casing 3 secured to the frame plate 1 and acts on a metallic bellows 4 sealed at the upper end to the casing 3. The upward movement of the plate 6 of the bellows with increase of pressure is limited by an adjustable stop 7 carried by a rod 59. Movement of the bellows is transmitted by a rod 8 to an arm 9 on a rock shaft 10. A bracket 12 on the shaft 10 can be adjusted relative to the arm 9 by means of a screw 12a passing through an extension 14 of the arm 9 into the bracket, a spring 13 holding the extension 14 against the head of the screw. The bracket 12 also carries a curved lever arm 15 adjustable axially and radially in the bracket and fixed by a screw 16. Parallel to the rockshaft 10 is a rock-shaft 17 having an arm 19 thereon. A " compensating " arm 20 is mounted on a third rock-shaft 21 approximately at right angles to the shafts 10, 17 the arm passing beneath arm 15 and over arm 19. If the shaft 21 is moved axially to displace the " compensating " arm, the leverage with which the shafts 10, 17 are coupled together will vary, thus altering the magnification of the indicating movement from the bellows 4. The rock-shafts 10, 17, 21 carry counter-balance weights 22, 23, 63. The shaft 17 carries an arm 24 connected by a pivoted link 25 to an arm in one with a toothed wheel gearing with a pinion 24 on the spindle of a pointer 29 moving over a dial 30. A hair spring on the pointer spindle tends to move the pointer from its zero position. " The compensating shaft 21 is mounted so that it can be moved axially in an adjustable carriage 32 by an arm 51 on a fourth rock shaft 33, a ball 52 engaging between collars 53 on the shaft. This shaft is rocked by movements of a rod 37 moved by a bellows 34 against a spring 40. The bellows is acted upon by the static pressure of the atmosphere. The rock shaft 33 carries an independently adjustable pair of curved lever arms 43, 44 and turns against the influence of a spring 48. The carriage 32 is adjustably mounted about the axis 54.

Title: Substituted propinyl-carbinols and process for the manufacture thereof
IPC: C07C29/42
Filed: 1954-06-03
Abstract: The invention comprises new substituted propinyl-carbinols of general formula <FORM:0751666/IV(a)/1> in which R is an ethyl group and R1 is a methyl or ethyl group or R and R1 together with the carbon atom to which they are attached form a cyclopentano-group.  They may be manufactured by reacting a propinyl halide, preferably the bromide, with zinc and a ketone of the general formula R-CO-R1 and hydrolysing the zinc compound so obtained. Preferably the reaction is carried out in the presence of an inert solvent, such as ether or a mixture of ether and benzene.  The preferred temperature for carrying out the reaction is about 40 DEG  C. and the zinc may be activated by heating it with iodine.  The zinc compound may be hydrolysed by means of dilute acids, water or ammonium salt solutions.  In the examples propinyl halide is reacted with zinc and (a) methyl ethyl ketone; (b) diethyl ketone; and (c) cyclopentanone to give methylethyl-propinyl carbinol, diethyl-propinyl carbinol and 1-hydroxy-1-propinyl-cyclopentane respectively.

Filed: 1935-06-06
Abstract: 459,291. Electric reproduction of kinema films. REKLAMAKTIEBOLAGET EPOK, 14, Drottninggatan, Stockholm. June 6, 1935, No. 16449. Convention date, June 6, 1934. [Class 118 (ii)] [See also Group XL] Relates to an electrical arrangement for controlling incandescent lamp screens adapted to reproduce pictures by means of gas discharge tubes, using successive transmission of part pictures and employing alternating or pulsating current for feeding the lamps and controlling the tubes. According to the invention, a plurality of double-anode grid-controlled gas discharge tubes are employed, each of which has co-ordinated with it two photoelectric cells, the cells being connected in groups, each adapted to control a group of lamps, the arrangement being such that each group of photo-cells has a positive voltage applied at the same time as the corresponding group of lamps. The source of voltage for the cells may be the centre-tapped secondary winding of a transformer or a switching device for feeding a direct current intermittently. As shown, one pair of cells 1, 1<a> is associated with the double-anode grid-controlled gas discharge tube 8, whilst another pair of cells 2, 2a is associated with the other tube 9. The cells are connected as shown to the centre-tapped secondary of a transformer 3 which is connected to the same source of A.C. supply as the transformer 13, the centre-tapped secondary of which is connected as shown with the lamps 11, 11<a> and 12, 12<a> connected to the anodes 5, 5<a> of the tubes 8, 9 respectively. With this arrangement, the cells 1, 2 have a positive voltage applied thereto and the lamps 11, 12 are lit up during one half-wave and the cells 1<a>, 2<a> have a similar voltage applied thereto, and the lamps 11<a>, 12<a> are lit up during the other half-wave. Instead of feeding the groups of cells through the transformer 3, they may be fed through an inductance and capacity respectively. Specification 432,501, [Group XL], is referred to.

Abstract: 859,112. Handling nuclear fuel elements. FAIRY CO. Ltd., May 22, 1959 [May 23, 1958], No. 16591/58. Class 39(4). [Also in Group XXX] A grab for lowering a fuel element down a duct into the core of a reactor and for retrieving the fuel element from the core comprises a body 12 having a square-section upper part 12A supported by a hoist cable 10 in a square-section guide tube 13 situated within the duct. An armature 19 is mounted for rotation about a vertical axis by a sleeve 22 secured thereto and having a circumferential flange 23 engaging a carbon bearing 18 mounted in the lower circular-section part 12B of the body 12. The part 12B has a pair of tapered slots 16 leading to parallel-sided slots 17 whilst the sleeve 22 has a pair of inverted J-shaped locking slots 29. Thus when the slots 17 are in alignment with the entrances 29A of the slots 29, as shown, the grab may be lowered on to a fuel element so that a diametrical cross-bar on the upper end of the fuel element enters the slots 29. The sleeve 22 is then rotated into a locking position in which the closed ends 29B of the slots 29 are in alignment with the slots 17 and in this condition of the grab the fuel element cannot be released. The sleeve is rotated by a field system 25 having four magnetic cores 25B wound with coils 25A, this field system being secured to the tube 13 within a casing 28. The four cores 25B are angularly spaced at 90 degrees and co-operate with four similarly-spaced pole pieces 24 in the armature 19 whereby the sleeve 22 may be rotated when the armature is within the field system 25, the direction of rotation being determined by energizing the coils 24A with appropriate polarity. The system 25 is shown situated at the lower end of the tube 13 and a similar system is also provided at the upper end.

Title: Improvements in the selective protection of selections of an electric transmission line
IPC: H02H3/30
Filed: 1945-06-29
Abstract: 631,726. Protective cut-out arrangements. UNION D'ELECTRICITE. June 29, 1945, No. 16652. Convention date, Sept. 10, 1943. [Class 38(v)] In a protective system for a sectionalized transmission line employing at each section-end a phase comparator which constantly supplies a voltage, the sense of which depends on the phase-relationship at the two ends, an auxiliary voltage is brought into effect when the current is no longer received from the far end, and is arranged to be in phase-opposition to the near-end current so as to produce tripping. The invention is shown in its application to the systems of Specification 631,725 parts of which are' reproduced in Figs. 1 and 2, (not shown). At each end, Fig. 6, a comparator device BC 1  is combined with a no-volt relay Rm 1  which, when there is no current in the transmission line TR (i.e. when the line is broken, or the transmission breaks down, or the section is fed from one end only), opens contact C. to disconnect the line TR, and closes contacts C<SP>1</SP> to connect the comparator to a device E, which supplies the auxiliary voltage, provided that an overload relay RM 1  has also closed its contacts. In its application to a 3-phase system, Fig. 7, comparators BC 1  .. BC 3 , and their associated no-volt and overload relays Rm, RM, are provided for each phase, the devices E being supplied from potential transformers Tp 1  .. Tp 3  with a voltage derived from the other two phases and in quadrature (leading) with that of the phase concerned, Fig. 12, (not shown). Voltage limiters L are provided for limiting the voltage applied to the comparators from the remote end, Fig. 13, (not shown). By connecting a resistance 20 in the circuit of valve l and in the cathodegrid circuit of an auxiliary valve 30, Fig. 10, an alarm 40 may be operated when no current from the remote end arrives. Dephasers. d, Fig. 7, may be provided for correcting the phase difference which may result during transmission.

Title: Improvements in arrangements for the automatic starting and re-synchronising of synchronous phase converters
IPC: H02K47/30
Filed: 1924-07-11
Abstract: 226,118. Kand¾, K. von. July 11, 1924. Synchronizing dynamo-electric machines.-In an arrangement for automatically re-synchronizing a synchronous phase converter which has fallen out of step, the secondary circuit Us of the phase converter is provided with an automatic circuit-breaker J controlled by wattmeters W<1>, W<2> in the primary and secondary circuits Up, Us of the converter, the arrangement being such that if the effect of the wattmeter W<2> preponderates, the circuit-breaker is opened. The wattmeters act in opposite directions on a contact-lever f which co-operates with a fixed contact h to connect the redease magnet r of the circuit-breaker J to a source of current B. Simultaneously with the opening of the circuit breaker J, an electromagnet S is energized to move a starting-switch K into the position I in which it is held by a tooth e<1> on a spring-controlled pawl E pivoted at n. In this position, the exciting circuit (not shown) of the phase converter is opened, and the starting motor or artificial phase of the converter is connected up, whereupon the converter is speeded up to synchronism or rs started if it has already come to rest. Immediately before synchronism is reached,. an electromagnet v connected to the secondary circuit of the converter is e.nergized and attracts the pawl E, thereby releasing the switch K which moves into the position II where, it is held by the tooth e<2>. In this position the starting device is disconnected so that the converter runs as a single-phase induction motor, and the circuit of the electromagnet v is broken at a contact z. The pawl E thereupon returns to its normal position, moving slowly on account of its inertia, and the switch K is released and returns to the position III in which the exciting circuit of the phase converter is again connected up. The switch J may then be closed and the motor M connected up. If speed control of the motor M is effected by a system of pole changing involving an alteration in the number of phases, the constants of one or both of the wattmeters must be simultaneously altered. This may be done by providing the appropriate wattmeter with a regulating resistance R, the controlling member of which is rigidly connected with the switch which effects the pole changing of the motor.
