Abstract: 221,412. La Mare, F. T. de, and Gibert, F. E. Jan. 19, 1924. Jacks.-In fluid-pressure actuated jacks of the kind comprising one or more pumps arranged to transmit a motive impulse to the piston of the jack at each stroke of an oscillating actuating lever, the discharge stroke of the pumps 7 is effected by the lever 14 pressing upon the projecting extremities of the pump pistons 9 and the suction stroke. by the engagement of forked yokes 20 attached to the lever with pins 22 fixed to the pistons. The head 25 of the jack is attached to the closed upper end of a cylinder 24 which is disposed between cylinders 6, 23 screwed into the base 1 of the jack. The pumps discharge into a conduit 29 which communicates with the cylinder 23 by an inlet controlled by a ball valve 30. An aperture 23<a> in the head of the. cylinder 23 allows fluid to pass into the cylinder 24. A bent piece 31 of spring steel normally holds the ball on its seating. The conduits 34, 35 connecting the reservoir 6 and pumps contain spring-pressed ball valves 36. A conduit is also provided by which direct ccmmunication can be effected between the conduit 29 and reservoir 6 when the load is to be lowered.

Interlocking and g u a r d i n g against wrong movement; automatic speed or power control; hydraulic transmission. - Comprises an internal-combustion engine locomotive in which a heavy-oil engine A<1>, Fig. 1, drives coupled track wheels through an epicyclic change-speed gear C controlled by plate clutches, bevel reversing gear F, and other mechanism, the plate clutches being controlled by a fluid-pressure system. The fluid-pressure system employed is preferably such as those described in Specifications 243,707 and 245,426, in which a pump M, Fig. 6, supplies pressure liquid through a pipe M<9> to a valve box Q having a piston valve R controlled automatically by a pilot valve R' actuated by a centrifugal governor in accordance with the road speed of the locomotive, the liquid then passing through a hand-actuated valve U distributing the liquid in proper sequence to pipes C<1> - - C<4> controlling the clutches or brakes of the epicyclic gear shown in Fig. 2. The engine shaft A<2> drives the first shaft A<3> of the change-speed gear through a coupling B in which relative movement between two members caused by the torque transmitted is utilized to actuate a bye-pass valve B', Fig. 6, and thereby control the change-speed gear, (1) by causing the gear clutches to engage gradually, and (2) by disengaging the gear if the torque becomes excessive. This coupling and the change-speed gear are described in Specification 243,707. [Class 80 (ii), Gearing, Variable-speed' &c.]. The bevel reversing gear comprises a driving pinion F which can be engaged by either of two bevel wheels F<4> fixed on a slidable shaft F<1> which is moved axially to effect this engagement by worm gearing H and a screw-and-nut F', F<10>. The worm shaft H<1> drives a nut H<6> screwed on a rod H' normally locked in one'of three positions. by a pin P on a piston P<1> which is embodied in the fluid pressure system described in the beforementioned Specifications, so that the reversing gear cannot be changed unless the locomotive is stationary and the brakes are applied.

To join two lengths of the ducting together they are placed in axial alignment with their ends in engagement and with a rubber or plastic ring 25 of dumb-bell cross-section stretched elastically around the adjacent portions of the ends (see particularly, Fig. 8). The joint is completed by a divided clamping ring 26. The ring is in two or three part circular sections. For connecting the ducting to a fan casing a flanged ring can be attached to the end of a length of ducting by the means described for connecting two lengths of ducting. Each length of ducting may be formed from three or more part cylindrical pressings. The ducting need not be of cylindrical cross-section but may be of polygonal or oval cross section.

Title: Improvements in apparatus for wrapping, or packeting, more especially intended for wrapping, or packeting, cigarettes, or the like
IPC: B65B19/22
Filed: 1922-01-24
Abstract: 194,476. Price, J. W. Jan. 24, 1922. Packeting by wrapping-up.-Relates to apparatus for wrapping-up batches of cigarettes &c. which may have been enclosed previously in foil, paper, &c. The apparatus is of the type in which a batch of cigarettes &c. is temporarily held between a pair of reciprocable former plates which carry them towards a wrapper, the cigarettes being subsequently pushed from between the plates by an associate plunger capable of moving at times with, and at other times independently of the former plates. According to the invention, the plates and the plunger are both caused to advance and retract. Continuously at the same times, and at required times, the plunger is caused to travel at an accelerated rate and to a greater extent than the plates, so that the plunger pushes the cigarettes from the plates while the former plates are advancing. The cigarettes &c. are introduced by hand or otherwise between the plates 26, 26<a>, Figs. 1 and 9, carried by a sliding member 9 actuated by a rotatable crank 10 and slotted arm 15. A wrapper 47 is fed into a shoot 48 and is supported in the correct position by an adjustable stop 53. The sliding member 9 moves to the right, carrying with it the plates 26, 26<a>, and a plunger 39 is operated by a bell-crank lever 33 and cam 38 to move forwards relatively to the plates 26, 26<a> and to engage the rear of the article, moving it to the right until the front end coincides with the leading edges of the plates. The plunger and plates then move forwards in unison while the roller on the bell-crank lever traverses the horizontal part of the cam and carry the article and wrapper between folding plates 57, 60, Figs. 1 and 7. At the same time side folders 58<a>, Fig. 1, fold in the projecting end portions b, the relative positions of the article and wrapper being as shown in Fig. 12. The continued forward movement takes the package past folders 63, and 59, 59<a>, which fold the parts c, 71, Fig. 14. Prior to the last fold 71 being made, a strip of adhesive is deposited on the flap by rollers 70, 70<a> supplied from rollers 69, 69<a> in contact with a roll 66 in a bath 65 of adhesive. The amount supplied is adjusted by a movable scraping member 67. As the plates 26, 26<a> are nearing the end of their outward travel, the plunger 39 is accelerated relatively thereto by the configuration of the cam 38 and thrusts the partially wrapped package from between the plates into a shoot 91, Fig. 7, in which it is retained by friction. A plunger 93 is operated to force the pile downwards out of the shoot. Alternatively, the packages may be delivered by the plunger 39 into the mould box of a bag-closing apparatus or into a receptacle.

Title: Process for preparing n-(ª‰-substituted-ethyl) piperazines
IPC: C07D295/084
Filed: 1958-01-22
Abstract: Compounds of the general formula <FORM:0838744/IV (b)/1> (wherein R represents a phenyl or cyclohexyl group) are prepared by refluxing an excess of a phenylmagnesium halide with N-methyl-N1-piperazineacetic acid ethyl ester in an organic solvent, decomposing the Grignard complex, filtering off the solid, concentrating the filtrate to dryness and fractionating the oily residue, and, if desired, catalytically hydrogenating one of the phenyl groups in the product. Advantageously the dihydrochloride of the compound in which R is phenyl is catalytically hydrogenated (e.g. in the presence of platinum oxide), and a solution of the resulting dihydrochloride of the compound in which R is cyclohexyl may be rendered strongly alkaline to liberate the base which, after separation by extraction with an organic solvent, may be converted to its metho-methylsulphate by reaction with dimethyl sulphate in an organic solvent.  N - Methyl - N1 - piperazineacetic acid ethyl ester is prepared by refluxing approximately equimolar amounts of N-methylpiperazine and ethyl chloracetate.  Reference has been directed by the Comptroller to Specification 789,704.
