Title: Improvements in or relating to automatic paste feed mechanism for automatic can labelling machines
IPC: B65C9/22
Filed: 1946-08-06
Abstract: 630,683. Labelling-machines. BINGHAM, D. W. Aug. 6, 1946, No. 23342. [Class 73] An automatic can labelling machine includes a rotary feed pump for supplying paste to paste-applying means, having driving mechanism for intermittently operating the pump comprising a ratchet wheel on the pump shaft, a power operable plate mounted upon the pump shaft to oscillate thereon, a latch member pivotal into the path of a spring- influenced pawl mounted on said plate for disengaging the pawl from the ratchet wheel, and latch control means operable by the cans as they pass through the labelling machine. Cans 3, Fig. 3, are rolled along a guideway 2 over a stack of labels and spots of paste applied to each can are pressed into contact with the leading edge of the topmost label which is thus wrapped around the can. Paste is applied to the trailing edge of each label through a hollow bar 4 mounted above the stack and supplied with paste from a reservoir 6 by a pump 7 and tubing 8. The pump 7 is operated intermittently by mechanism including  a ratchet wheel 11, Fig., 2, fitted to the pump shaft 12, a spring influenced pawl 13 pivotally mounted on plates 14 rotatable on the shaft 12, and a power driven reciprocating rod 18 for imparting rotary oscillation to the plates 14. A pivoted latch plate 21 normally contacts the tail piece 22 of the pawl 13 so as to maintain the pawl out of engagement with its ratchet wheel. As each can passes along the guideway 2 a trigger plate 36 is depressed and actuates a push rod 37 to swing the latch plate 21 out of engagement with the pawl 13. The latter thereby engages the ratchet wheel 11 and partially rotates the pump shaft 12 to supply a predetermined quantity of paste to the topmost label. The quantity of paste supplied at each injection may be varied by adjustment of a pivoted arm 26 adapted to disengage the pawl 13 from the wheel 11 before the completion of the forward movement of the plates 14. The operable position of the arm 26 is adjustable by a screw 27.

Title: Improvements in or relating to diamonds
Inventor: DUGDALE RONALD ARTHUR
IPC: A44C17/00
Filed: 1952-09-22
Abstract: A process for colouring in the range blue to blue-green a substantially colourless diamond comprises irradiating the diamond with electrons of an energy within a range selected to produce mainly single Frenkel defects in the diamond lattice. Diamonds may be mounted in Woods metal on a water-cooled pipe and subjected to bombardment by electrons from a Van de Graaf machine at an energy of 1 Mev for one hour to give an intergrated electron flux of about 1018 electrons per square cm.  The diamonds are then heated at 500 DEG C. for one hour.  The electrons may have energies between 0.5 Mev to 2 Mev.  The process may also be carried out by gamma rays which should have energies of about 1 Mev and which cause the emmission of electrons within the diamond.

Filed: 1948-09-09
Abstract: 810,440. Automatic control systems for gyros. SPERRY GYROSCOPE CO. Ltd. Sept. 9, 1949 [Sept. 9, 1948], No. 23745/48. Class 38 (4). [Also in Group XX] Gyroscopic apparatus stabilizing a platform 1 on, say, an aircraft, about perpendicular axes A, A<SP>1</SP>, B, B<SP>1</SP>, comprises a continuously rotated turntable 6 carrying a rateof-turn gyro 10. The housing of gyro 10 is carried in bearings 11 on the turntable 6, the axis of which normally coincides with the spin axis of the gyro 10. Angular displacement of the craft about A, A<SP>1</SP> or B, B<SP>1</SP> results in precession of the gyro 10, which produces a cyclically varying signal in inductive pick-off devices 13, 14, which signal is amplified and applied to a coil 17. Coils 19, 20 mounted on platform 1 are arranged parallel to B, B<SP>1</SP>, A, A<SP>1</SP> when the plane containing their axes is parallel to the plane containing B, B<SP>1</SP>, A, A<SP>1</SP>, and coil 17 is rotated synchronously with its axis parallel to D, D<SP>1</SP>, coils 17, 19, 20 forming a sine-cosine resolver. The amplified outputs from coils 19, 20 energize stabilizing torque motors 4, 5. High accuracy is claimed as irregularities of the gyro 10 produce opposing signals that cancel. The angular momentum of the turntable 6 is high, forming a stabilizing gyro in itself, affording an averaging control over the cyclic variation of the signal produced in the resolver 17, 19, 20. Alternatively or additionally, averaging control may be provided by electrically derived averages of the signal produced.

Title: Improvements in or relating to the preparation of steroid substances
Inventor: HAMLET JOHN CHRISTOPHER
IPC: C07J75/00
Filed: 1954-08-16
Abstract: 3-Esters of 11,23-dibromohecogenin are prepared by bromination of 3-esters of hecogenin in an inert, substantially non-polar organic solvent.  The reaction is preferably effected between 5 DEG  and 30 DEG  C. (e.g. at about 15 DEG  C. in benzene or at 20-25 DEG  C. in dioxan), using between 2.0 and 2.5 (e.g. 2.3) mols of bromine to 1 mol. of the ester, which may be completely dissolved or partly suspended in the solvent, the preferred concentration of ester being about 12.5 per cent w./v.  It is desirable to reduce the concentration of hydrogen bromide in the reaction mixture immediately after the addition of the bromine, conveniently by applying a partial vacuum (e.g. a pressure of 20-56 cm. Hg) and simultaneously allowing a current of air to sweep over the surface of the liquid.  The desired product may be isolated by evaporaton of the solvent and crystallization of the residue, e.g. from alcohol, or, when using dioxan as solvent, by precipitation with water and extraction of impurities from the separated and dried precipitate by stirring with methanol.  By-products present in the crystallization mother liquors or the methanolic extract, as the case may be, may be debrominated (e.g. with zinc dust and acetic acid) to recover some hecogenin ester for re-use, or 23-bromohecogenin ester for further bromination. Examples describe the preparation of 11a  : 23-dibromohecogenin acetate (probably containing traces of 11b -epimer) by bromination of hecogenin acetate in (1) and (2) benzene, and (3) dioxan. Specification 773,150 is referred to.  Reference has been directed by the Comptroller to Specifications 721,953 and 738,828.
