Title: Improvements in or relating to means for temporarily attaching articles to aircraft
IPC: B64D1/06
Filed: 1945-05-30
Abstract: 594,609. Steadying loads suspended from aircraft. BLACKBURN AIRCRAFT, Ltd., and THARRATT, A. May 30, 1945, No. 13590. [Class 78(iv)] [Also in Group XXI] Mechanism for adjusting a pair 15 and a second pair 24 of retaining crutches for temporarily attaching articles to aircraft comprises an operating shaft 1 which is connected to. a differential gearing 2 which in turn drives two shafts 6, 7, connected to the adjusting means of the crutches. By this means the two shafts may be simultaneously rotated in either direction but when one pair is arrested, as for instance when it engages the load, all the drive is taken to the shaft of the other pair. The crutches 15, 24, shown are constructed as in Specification 594,608, [Group XXI], each consisting of a pair of members which are open and closed by nuts on a threaded shaft 10 or-19. These shafts are geared to the hollow shafts 6, 7, leading to the differential 3. Thus when the shaft 1 is rotated by a handle the shafts 6, 7, will both move but when one is arrested the bevel gears 3 of the differential will rotate and carry all the drive to the other shaft.

Title: Carbonyls and the process for their preparation
IPC: C01G1/04
Filed: 1960-04-19
Abstract: Compounds containing the [V(CO)6] group in anionic form or in the form of an electrically neutral molecule are made by reacting a compound containing a cation which comprises vanadium with carbon monoxide in the presence of reducing systems, comprising a metal more electropositive than vanadium or a derivative of the metal having reducing properties.  The vanadium compound may be dissolved or suspended in an inert solvent e.g. hydrocarbons or ethers and the carbon monoxide may be admixed with hydrogen.  The reducing systems may contain an amine e.g. pyridine, quinoline or an aliphatic trialkylamine.  The compounds containing cationic vanadium may be a halide of formula VXn in which n=2,3,4 or 5 and X=Cl, Br or I or an oxyhalide of formula VOXn in which n=1,2 or 3 and X=Cl, Br or I or a salt of an organic anion, e.g. an acetate, propionate, butyrate, ethylhexanoate or naphthenate.  The compounds of vanadium include vanadium hexacarbonyl itself, vanadium hydrocarbonyl, and compounds of formula Me+ [V(Co)6]1 where Me+ is Ni+, Na+, K+, Rb+, Cs+, Ag+, Cu+, Tl+, Hg+, NH4+ or NR4+ where R is an organic hydrocarbon radical, Me++ [V(Co)6]12 where Me++ is Ca++, Sr++, Ba++, Fe++, Co++, Ni++, Cu++, Hg++, Mg++, Zn++, Pb++, Cd++, Cr++, or Mn++, or Me (B)n+x [V(CO)6]-x where Me is a metal, B is a base, e.g. ammonia, an aliphatic amine, pyridine or a homologue thereof a  a 1 dipyridyl, or o-phenanthroline (see Group IV(b)).  Comparative examples are given. V(CO)6 may be thermally decomposed so as to deposit vanadium on supports such as kieselguhr, alumina and silica.ALSO:The invention comprises (1) compounds of the formula:-  <FORM:0938116/IV(a)/1> in which Me is a cation such as Li, Na, K, Rb, Cs, Ag, Cu, Tl, Hg, Ca, Sr, Ba, Fe, Co, Ni, Mg, Zu, Pb, Cd, Cr, Mn, NH4 or NR4 (in which R represents a substituted or unsubstituted hydrocarbon radical) and x is the valency of Me; and (2) compounds of the formula:- <FORM:0938116/IV(a)/2> in which Me is a metal cation (including V), B is a Lewis base such as an aliphatic amine (e.g. ethylene diamine), pyridine or a homologue thereof, a ,a 1-dipyridyl, ortho-phenanthroline, an alcohol (e.g. methanol), a ketone (e.g. acetone), an aliphatic ether (e.g. diethyl, di-isopropyl or dibutyl ether), or a cyclic ether (e.g. dioxan and tetrahydrofuran), and n indicates the number of Lewis base molecules (B) co-ordinated. Compounds having the formula (1) in which Me represents NR4 are prepared by treating a solution containing a [V(CO)6]- ion with a source of a cation NR4+. Compounds having the formula (2) are prepared by co-ordinating compounds of the formula (1) with a Lewis base, by treating V(CO)6 with an Me(B)n halide or, where compounds of the formula V(B)n ++[V(CO)6]2- are required, by a dismutation reaction between V(CO)6 and a Lewis base.

Title: Improvements in or relating to brake-operating mechanisms
IPC: B60T11/04
Filed: 1943-08-23
Abstract: 579,377. Brakes. TARLTON, F. H. Aug. 23, 1943, No. 13729. [Class 103 (i)] An actuating lever or member through which a vehicle or other brake is applied and released by a pedal is arranged to be held or restrained against brake releasing movement by an auxiliary or "grab" brake, which is controlled by a hand lever and also by the actuating lever, the arrangement being such that release movement of the actuating lever consequent upon release of the grab brake by the hand lever tends to re-apply the grab brake. An actuating lever 13 pivoted on a fixed pivot 12 is connected by the rod 19 to the main brakes and by link 16 to to the brake pedal 17 pivoted at 18. The anchor plate 22 of an internal expanding brake, the shoes of which are arranged to engage a fixed drum, is freely mounted on the pivot 12. The cam lever 27 of this "grab" brake is connected by cable 28 to the hand lever. The main brake may thus be applied by the pedal, the lever 13 assuming the broken-line position. Then by operation of the hand lever the plate 22 and lever 27 are first turned bodily about'the pivot 12 until a stop 29 on the plate having engaged the lever 13, the grab brake is applied. The main brake is then held "on" by engagement of the lever 13 with the stop 29, the reaction of the lever and thus of the main brake being taken in part by the hand lever which may be held by a detent, but mainly by the frictional engagement of the shoes of the grab brake with the drum. Return movement of the hand lever releases the grab brake but the rotation of the plate 22 by the consequent release movement of the lever 13 tends to return the lever 27 to its application position relatively to the plate and thus to re-apply the grab brake so that the release of the main brake is kept under control by the hand lever. The grab brake may have strong pull-off springs so that the main brake may be partially applied before the grab brake. This enables the operator to correct over-release of the main brake in part. In the modification shown in Fig. 3 the grab brake is provided by winding the cable 33, which is connected to the hand lever, around a fixed drum 30, the cable being connected to the link 16 by which the lever 13 is connected to the pedal. Application of the brake by the pedal slackens the cable which may then be tightened by the hand lever to hold the brake applied and be subsequently slackened by the hand lever to release the brake. In order that the main brake may be capable of partial application by the hand' lever a stiff cable that tends to unwind itself from the drum may be used.

Title: Improvements in Mine Signalling Apparatus.
IPC: B66B19/06
Filed: 1917-09-26
Abstract: 118,354. Clay Cross Co., and Strong', J. W. Sept. 26, 1917. Mine and colliery signals. - In mine signalling apparatus of step-by-step type, the signal indication is only cancelled when the engine starts, and a signalling impulse received before the previous signal is cancelled returns the indicating pointer to indicate one impulse, where it remains until returned to zero by the engine. The numerals &c. on the dial may be transparent, and each provided with a lamp, a switch moving step by step with the pointer so that the indication registered by the pointer is illuminated. A second switch may be provided to maintain illumination of the cautionary " men " signal when the subsequent active signal is given. A striker rod B reciprocated mechanically or electrically in the usual way has a pawl b operating the bell-hammer to give audible signals, and a pawl b<1> which moves a ratchet wheel D and pointer c one step for each impulse. The wheel D is retained by a detent d<1> disengaged to cancel the signal by a lever M operated from the engine. An insulating drum F is secured to the pointer spindle and has contacts f co-operating with fixed spring contacts (not shown) so that the lamps in the dial box E are successively illuminated as the drum is rotated. To maintain illumination of the " men " signal when the subsequent active signal is given, a second rotary switch (not shown) is provided in the dial box E. This switch is only moved when the active signal impulse is given and thereupon closes an alternative circuit through the cautionary signal lamp. A dash-pot G has a piston which is raised by the first signal impulse, and then falls until an adjustable projection g<4> bears upon a lever H. The lower end of the lever causes a sliding member (not shown) to bear against a projection (not shown) on the detent d<1>. As the detent rises when a subsequent impulse is given, the sliding member passes under a projection and holds the detent d<1> out of engagement. The ratchet wheel thereupon returns until arrested at the first indication by a single-tooth ratchet and detent (not shown). This detent is only released by the lever M to return the pointer to zero. When the ratchet wheel D is in the zero position, a cam projection h<2> holds the lever H and its sliding member clear of the detent d<1>, allowing it to engage the ratchet wheel.
