Title: Improvements in or relating to diethylphenylacetic acid esters
Inventor: PETROW VLADIMIR
IPC: C07D295/088
Filed: 1956-01-04
Abstract: The invention comprises esters of the formula <FORM:0801725/IV (b)/1> (wherein R and R1 are alkyl groups containing together not more than 12 carbon atoms or together with the adjacent nitrogen atom form a pyrrolidino, piperideino or piperidino radical) and their preparation by converting, by known methods, diethylphenylacetic acid into the acid halide and condensing this with the appropriately substituted ethoxyethyl alcohol or by reacting a metal salt of diethylphenylacetic acid with a b :b 1-dihalogeno-ethyl ether and reacting the resulting b -halogeno-ethoxyethyl ester with the appropriate amine.  In examples: (1) ethyl chloride in dry ether is added to a mixture of phenylacetonitrile and sodium in liquid ammonia containing a catalytic amount of ferric chloride to give, on working up, diethylphenylacetonitrile, this is refluxed with KOH in ethylene glycol to give diethylphenylacetic acid, this is refluxed with b :b 1-dichlorodiethylether in ethylene glycol containing sodium hydroxide to yield 2-(b -chloroethoxy)-ethyl diethylphenylacetate and this with diethylamine at 140 DEG  C. gives 2-(b -diethylaminoethoxy)-ethyl diethylphenylacetate; (2) diethylphenylacetyl chloride is prepared from the free acid and thionyl chloride and is then refluxed with 2-(b -N-pyrrolidinoethoxy)-ethanol in chloroform to give, on working up, 2-(b -N-pyrrolidino-ethoxy)-ethyl diethylphenylacetate; (3) 2 - (b  - N - pyrrolidinoethoxy)-ethyl diethylphenylacetate is prepared by refluxing pyrrolidine with the corresponding 2 - (b  - chloroethoxy) - compound; (4) 2-(b -N-piperidino-ethoxy)-ethyl diethylphenyl acetate (citrate also described) is prepared by the method of (3); (5) 2-(b -ND 3-piperideinoethoxy) - ethyl diethylphenylacetate is prepared similarly; (6) 2-(b -N-ethylmethylaminoethoxy)-ethyl diethylphenylacetate is prepared by refluxing the appropriate chloro-compound with ethylmethylamine in n-hexanol; (7) to (9) 2 - (b  - N - ethylpropylamino - ethoxy) -, 2-(b -N-di - n - butylamino - ethoxy)- and 2 - (b  - N - di-n-hexylaminoethoxy) - ethyl diethylphenylacetates are similarly prepared.

Title: Loader vehicles
IPC: E02F3/36
Filed: 1975-01-04
Abstract: 1475202 Hitch for coupling a load-carrying implement to a lift boom MASSEY-FERGUSON-PERKINS Ltd 2 Jan 1976 [4 Jan 1975] 352/75 Heading E1F A hitch coupling for connecting a loadcarrying implement, e.g. a scoop or shovel, to load-lifting means, e.g. a tractor-mounted, vertically swingable boom 12, comprises a bracket provided with securing means movable relative to the bracket first to lock the bracket to the lifting means and then to lock, on further movement, the implement to the bracket. Preferably the bracket comprises a pair of horizontally extending plates 30, 32 interconnected by four vertical plates 34, 36, 38, 40 arranged in pairs at opposite ends of the horizontal plates, each of said pairs of vertical plates straddling an aperture 35, 37 in one, preferably the lower one 32, of said horizontal plates, the said vertical plates having axially aligned bushes 46 therein adjacent the apertures. The bushes receive a pair of oppositely movable pins 56, 58 by which the bracket is first secured to the lifting means 12 and then to the implement. The pins are moved conjointly in opposite directions by a mechanism comprising a lever 70 pivotally connected at 68 on one horizontal plate 32 and a pair of links 64 pivoted to the lever on opposite sides of the pivotal connection to the pins. Apertured lugs on the lifting means and on the implement are so located in the apertures 35 in the plates 32 that initial movement of the lever causes outward axial movement of the pins into apertures in lugs of the lifting means and further movement of the lever causes the pins to enter apertures in the lugs on the implement. In the connection of an implement to the lifting means the bracket is connected to the lifting means and is advanced and lifted upwards so that the plate 30 engages beneath a bracket on the implement, which is then raised by the lifting means through this now established interconnection so that it swings back against the bracket so that the apertured lugs on the implement enter the apertures on the beam 30, 32 so that the pins 56, 58 can be entered into the lugs to lock the implement to the bracket. Stop means 74, 76 are provided on the plate 32 for exerting control on the movement of the lever.

Title: Improvements in or relating to electrical arc discharge tubes
IPC: H01J13/50
Filed: 1939-01-06
Abstract: 523,485. Metal-vapour apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 6, 1939, No. 551. Convention date, Jan. 7, 1938. Drawings to Specification. [Class 39 (i)] An apparatus with a mercury cathode is provided with two anodes, one of which is perforated, the discharge to the second anode passing through the perforation ; it is stated that while a discharge is passing to the perforated anode the discharge to the second anode maintains the same voltage for different current strengths up to a certain current value, after which the current remains substantially constant for all voltages, but becomes intermittent above a certain voltage ; if the discharge to the perforated anode is then stopped the discharge to the second anode is permanently interrupted. If a coil is arranged to produce a field parallel to the discharge the limiting value of the current is lowered and a sufficiently strong field will break the current. The effect of the coil is enhanced if a deflector, preferably of magnetic material, is placed between the cathode and the opening in the perforated anode. Two coils may be employed in opposition so that if the current in either is interrupted the current in the other stops the discharge, and applications of this arrangement to overload interrupters are described. The apparatus may contain a succession of perforated anodes, the discharge to each being regulated by those to the previous ones. Several constructions are described, including arrangements of two non-perforated anodes for use as a full-wave rectifier. Specifications 404,455 and 440,636 are referred to.

Filed: 1990-01-08
Abstract: PURPOSE:To surely transmit the destination floor call to be registered to an elevator by registering the destination floor call by operating a registering button after operating an arbitrary numeral and preventing the errorneous operation or errorneous registration of a call registering circuit. CONSTITUTION:When the sixth floor call is to be registered, destination floor buttons 2 and 4 are operated. Accordingly, the holding signal relays 2L and 4L of the destination floor buttons are turned ON. Then, a registering button signal relay TL is turned ON by operating a registering button T. Accordingly, a call registering signal relay 2C is turned ON by a call registering signal circuit -2La-TLa-2C-, and a call registering signal relay 4C is turned ON similarly. The call registering signal relays 2C and 4C are self-retained until the actual call is registered by a call registering circuit. The actual destination floor call is registered and memorized by the registration of the destination floor call and a memory circuit.
