Abstract: 668,657. Capsuling machines. WILLCOCK, J., and HANNAH, G. Feb. 20, 1951. [Nov. 21, 1949] No. 29701/49. Class 125(ii). In a capsuling- machine of the type wherein the capsule is sealed by fluid pressure supplied to a pressure chamber a<SP>2</SP> containing a rubber or like cup, bottles with capsules loosely applied thereto are supplied by a feed conveyer c from which they are transferred one at a time by a finger k<SP>1</SP> to a vertically r e ciprocating bottle-rest g from which the capsuled bottle is pushed on to a discharge conveyer c<SP>1</SP> by the next bottle fed by the finger k<SP>1</SP>. A framework having a table a carries vertical supports a<SP>1</SP> upon which the capsuling head a<SP>2</SP> is vertically adjustable by a rack mechanism. A motor b drives through gearing b<SP>1</SP> a pump b<SP>2</SP> supplying fluid under pressure through a pipe b<SP>4</SP> to the head a<SP>2</SP> whence the fluid can return to a sump b<SP>3</SP> by way of a valve b<SP>6</SP> and a pipe b<SP>7</SP>. When the valve b<SP>6</SP> is closed, the pressure in the head builds up and capsuling is effected. In supports h on the table is mounted a spindle h<SP>1</SP> on which is splined a block k carrying pivotally the finger k<SP>1</SP> acted on by a spring k<SP>2</SP> which gives if a bottle jams. The block k is traversed to and from the bottle rest g by a rack and pinion mechanism h<SP>5</SP>, i. During the return stroke, the finger k<SP>1</SP> is rotated through 90 degrees in a vertical plane, so as not to foul the bottles on the feed conveyer c, by the spindle h<SP>1</SP> being rotated by a rack and pinion device l<SP>1</SP>, l. The bottle rest g, carried on a stem g<SP>1</SP> is raised and lowered by a cam g<SP>3</SP>. The valve b<SP>6</SP> is periodically closed by an arm m'' acted on by a spring l<SP>3</SP> and a cam m<SP>1</SP>. The operation of the valve b<SP>6</SP>, the raising and lowering of the rest g, the movement of the conveyers c, c<SP>1</SP>, the advance of the finger k<SP>1</SP> and the rotation of the finger k<SP>1</SP> are all effected through suitable gearing and a slipping clutch by a motor e. In front of the feed conveyer is a bottle stop n. In a modification, the finger k<SP>1</SP> reciprocates between two bottle rests rising alternately each with its discharge conveyer. In this construction it is not necessary for the finger to be rotated through 90 degrees.

Title: Improvements in or relating to protective arrangements for electric distribution or supply systems
IPC: H02H3/347
Filed: 1925-11-26
Abstract: 250,494. Switchgear & Cowans, Ltd., and Neep, G. H. Nov. 26, 1925. Cut-out anangements. - In a distribution or supply system protected against overload or leakage or both, manually-operated switches 10 are utilized to connect any section to earth directly or through a resistance 11, thus producing an artificial earth, and so, by means of the leakage protective apparatus or the overload devices, or both, trip-out the circuit-breakers of the section. As shown applied to an AC, three-phase section protected by overload coils 5 which trip the eircuit-breaker and by core-balance leakage transformer 6 having a secondary winding 7 connected to the leakage tripping coil 8, one of the phases is connected, at will, to earth through the resistance 11 by closing the switch 10. This brings into action one or both of the tripping- devices to open the circuit-breaker. An earthing connection such as 9, 10, 11 may be associated with each section and, by arranging the trip coils with graded settings and the resistances 11 graded from section to section, when a switch 10 is closed only that tripping-device adjoining the artificial earth connection and on the side nearer to the source of supply is energized and no others. A master multiple switch at the station may be used instead of the single switches, or one or more limiting resistances variable to the requisite values to give the desired selectivity. The arrangement is applicable to normally insulated systems wherein the protective devices is brought into action by discharge across a sparkgap as in Specification 219,717. In such cases the switch 10 completes a circuit between its supply conductor and the earthed side of the spark-gap.

Title: Polymers of fluorinated organic compounds
Inventor: HASZELDINE ROBERT NEVILLE
IPC: C08G73/24
Filed: 1958-09-22
Abstract: A perfluorinated nitrosoalkane (RNO) and 1:1 difluoroethylene are copolymerized at at least 70 DEG C. and 30 atmospheres absolute to yield polymeric compounds having repeating units of the structure <FORM:0901207/IV(a)/1> where R is a perfluoroalkyl group and X is F and Y is H or vice versa.  It is preferred to use equimolar proportions of the monomers, which proportion is found in the product regardless of the initial proportions used.  The products range from oils to waxes and elastomeric gels.  The elastomeric properties can be enhanced by cross-linking, e.g. by heating with peroxides or amines.  The straight and cross-linked copolymers are insoluble in water but soluble in conventional organic solvents, e.g. ketones. They may be used as coolants, heat transfer media, coating and sealing compositions, flexible hosing and lubricants, especially under chemically corrosive conditions.  Trifluoronitrosomethane is copolymerized in the specific examples.  In Example 1 the conditions are 40 atmospheres and 100 DEG C. for 14 days to yield a viscous oil which is purified by solvent extraction with diethyl ether.  In Example 2 the conditions are 150 atmospheres and 80 DEG C. for 5 weeks to yield a gum rubber which is toughened by heating with dibenzoyl peroxide.ALSO:Polymers comprising structural units of the formula <FORM:0901207/IV (b)/1> where R is a perfluoroalkyl group and X is F and Y is H or vice versa are obtained by heating a perfluoronitrosoalkane with 1 : 1 difluoroethylene under pressure. To obtain high polymers (see Group IV(a)) a minimum temperature and pressure of 70 DEG C. and 30 atmospheres absolute is required.

Abstract: 1513306 Monitoring of seed dispensing DICKEY-JOHN CORP 18 July 1975 [14 Aug 1974] 30208/75 Heading AID [Also in Divisions G1 and G3] The rate at which seeds are fed from a dispenser to a plurality of planting drills is automatically controlled in response to first pulses from sensor 30 corresponding to individual seeds being sown, and second pulses from a sensor 21 corresponding to distance travelled by the drill, the second pulses being multiplied at 23 by a factor corresponding to the spacing between the rows, whereby the number of seeds planted per unit area is kept constant. The seed sensors 30 are not described, but there is one for each drill, their outputs being summed at 32. The distance sensor 21 is photo-electric (see Division G1, also Figs. 4..6, not shown). The seed and distance pulses are counted up and down respectively in a counter 29. If a "dead band" of counts is exceeded (because the seed pulses differ from the distance pulses more than a predetermined amount) a corrective motor 38 is driven to vary the transmission ratio between the seed dispenser and a road wheel 51 which drives it. The counter is associated with a second counter fed with pulses from a local oscillater: the arrangement is such that, if the error is small the motor is run for a short time, determined by the second counter, whereas if it is large the correcting motor runs continuously until the error is reduced. (Figs. 9, 10, not shown). Reference has been directed by the comptroller to Specification 1467966.
