Title: Improvements in or relating to the controlling of mining machines
IPC: E21C35/04
Filed: 1967-01-03
Abstract: 1,139,372. Mineral-mining machines. GEBR. EICKHOFF MASCHINENFABRIK U. EISENGIESSEREI m.b.H. 3 Jan., 1967 [12 Jan., 1966], No. 257/67. Heading E1F [Also in Division G3] A mining machine of the type arranged to be advanced by hydraulic mechanism including a pump controlled by an electromagnetic valve 44 comprises a number of electric motors such as 1, 2 each driving a cutting tool, and is provided with a control system for adjusting the output of the pump in dependence upon the load current taken by the motors. As shown, a signal proportional to the load current taken by motor 1 is derived from a transformer 3 and is compared with a reference voltage in a transistorised comparator circuit 5 which produces an output to energise a relay 21 if the load current is below a predetermined value, or an output to energise a relay 19 if the current is above the said value. Relay 19 has a normally open contact 23 and a normally closed contact 25, and relay 21 has a normally open contact 27. A sensing transformer 4, a comparator 6, a relay 20 with contacts 24, 26, and a relay 22 with a contact 28 are similarly associated with the motor 2. The contacts 25, 27, 28, 29 are in series with the "increase output" winding 34 of the valve 44, and the contacts 23, 24 are in parallel with the "decrease output" winding 37 of the valve 44 which is powered from a supply derived from a transformer 30. In operation, if both motors are loaded below their rated values, relays 21 and 22 are energised so that contacts 25, 27, 28, 29 are closed and the valve 44 thereby energised to increase the pump output, whereby the speed of advance of the mining machine is increased. Should one motor, say motor 1, thereby become, overloaded comparator 5 will produce an output to energise relay 19 instead of relay 21, contacts 25 and 27 will open, and contact 23 will close thereby to interrupt the "increase output" circuit of the pump 44 and to close the "decrease output" circuit, whereby the speed of advance of the mining machine is reduced and the machine is protected against overloading of any of its cutters.

Abstract: 620,087. Cathode-ray tubes. DODDS, J. M., MILLER, C. W., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Jan. 3, 1947, No. 268. [Class 39 (i)] [Also in Group XL (c)] A radial or spiral time-base for navigational purposes as in plan position indicators and variable-beam elevation display, comprises a cathode-ray tube with main deflector plates or coils D carrying potentials or currents in quadrature, so as to give a circular trace on the tube screen and means for producing an auxiliary magnetic field circumferentially of the tube, which deflects the beam radially in proportion to the time - base current. The auxiliary magnetic field is produced by a toroidal coil in which all but one side of each turn is screened substantially by a cylinder of magnetic material, which may be built up of three parts, S1, S2, S3. The main deflector plates or coils are controlled either by direct connection to or remote control from the directional aerial system of radar apparatus. The centre of rotation of the time-base may be offset from the centre of the screen and start at a suitable radius. The timebase may rotate through a greater or smaller angle than the directional aerial, and the trace start at a suitable radius to give an expanded centre display.

Locking by frictional and positive detents; band brakes.-Brakes for hand propelled vehicles of the kind in which the brake is applied upon release of the handle of the vehicle or relaxation of the pressure thereon are provided with means whereby a partial release of the handle applies a brake of the non-positive type and complete release effects a positive locking of the wheel. A disc g has frictional engagement with a disc i secured to the spokes of the wheelof the vehicle. The frictional grip of the disc g may be adjusted by splitting the disc and by connecting the split parts by a screw device. A compound bolt comprises a part e slidable in a fixed casing k and a part f slidable in the part e springs e<1>, f<1> being disposed respectively between the part f and the part e and between the part e and the casing k. The part f of the bolt is connected by a Bowden cable to a lever pivoted upon the vehicle handle whereby when the handle and the lever are grasped, both of the members e, f of the bolt are retracted. If the lever is partly released the bolt is moved bodily by the spring e<1> to engage one of the notches in the disc g, thereby applying a frictional braking action to the wheel but upon complete release of the lever the member f of the bolt is moved by the spring f<1> to engage a notch in the disc i so as positively to lock the wheel. The bolt is mounted upon the axle by a pair of clips one of which is secured to the casing of the bolt. Instead of the bolt being operated by a lever mounted in the handle, the handle itself may be rotatably or otherwise mounted for this purpose.

Title: Improvements in or relating to the manufacture of pentetheine-4-phosphate
Inventor: BADDILEY JAMES
IPC: C07F9/09
Filed: 1953-01-09
Abstract: The invention comprises 021 : S-aralkyl-protected pantetheines and comprises also a method of making 02 : S-aralkyl protected pantetheines in which an S-aralkyl-protected 2-mercaptoethylamine is condensed with a mixed anhydride of an O2-aralkyl protected pantothenic acid and a carbonic acid mono ester.  Preferably the mixed anhydride is a compound of the formula R.CO.O.CO.OR1 where R is an 021-aralkyl protected pantothenic acid residue of the formula HO.CH2.C.(CH3)2.CH(OR2).CO. NH.CH2CH2, wherein R2 is an aralkyl group and R1 is an alkyl group of up to five carbon atoms.  Suitably a mixed anhydride, obtained by condensation of an 021-aralkyl-protected pantothenic acid with a halogenoformic ester such as ethyl chloroformate in the presence of a strong tertiary base such as a trialkylamine or N - methyl - morpholine at - 10 DEG  C. to 0 DEG C., is condensed with an S-aralkyl-2-mercaptoethylamine at - 20 DEG C. to + 20 DEG  C.  The resulting 021 : S-aralkyl-protected pantetheine may be converted into pantetheine-41-phosphate by treating it under anhydrous conditions in the presence of a tertiary organic base with a diaralkyl halogenophosphonate followed by hydrogenolysis to remove the aralkyl groups.  Suitably the phosphorylation is effected by treatment with a dibenzyl-halogenophosphonate at - 40 DEG  C. to 0 DEG  C. in the presence of a pyridine base and hydrogenolysis is effected by treatment with an alkali-metal in liquid ammonia. The pantetheine-41-phosphate is purified by forming the lithium salt, precipitating the silver salt therefrom and converting the silver salt into the barium salt.  In an example 021-benzylpantothenic acid is treated with ethyl chloroformate in dimethylformamide in the presence of N-methyl-morpholine, the product is reacted with S-benzyl-2-mercapto ethylamine to give 021 : S-dibenzyl-pantetheine which is phosphorylated by dibenzyl chlorophosphonate in the presence of pyridine followed by hydrogenolysis by sodium in liquid ammonia to give pantetheine-41-phosphate which is separated as the lithium salt and purified via the silver and barium salts.  Starting material. 021 - Benzyl - panthothenic acid is made by treating 02-benzyl-pantolactone with b -alanine in the presence of dimethylamine.  Specifications 702,750 and 716,337 are referred to.
