Patent GB-333306-A (GB)
Title: Improvements in apparatus for filling bottles or other receptacles with liquids and sealing the same
IPC: B67C7/00
Filed: 1929-05-14
Abstract: 333,306. Howard, H. W., and Hayward, Tyler, & Co., Ltd. May 14, 1929. Bottling.-Relates to rotary bottling-machines with means for transferring syruped bottles to the filler and filled bottles to the sealer. According to the invention, the transferring mechanism comprises two oscillating lower arms 47 whereby a bottle to be filled is moved by one of the arms from a syruping block 11 onto a bottle rest q<1>, while a filled bottle is simultaneously moved by the other arm from the same bottle rest into the sealing position 16. The bottle rests 1-5 are adjustably mounted on a drum n so that they can operate with bottles of different heights. The lever arms 47 are oscillated on a spindle 21, and are adjustable thereon to correspond with the height of the bottle rests. The machine has a circular bottle guard 53 and radial bottle guards 55, which are actuated by springs 57 attached to lugs 58. Rollers 59 at the lower ends of the plates 55 engage a cam 60 as the guards approach the levers 47 to swing the plates clear of the levers and bottles. The lever arms 47 are mounted on a helical boss on the spindle 21 so that any vertical adjustment gives a corresponding angular adjustment to allow for the variation in diameter of bottles of different heights. The bottle rests are spring-pressed against the filler heads, and are cam-operated. Means are provided to prevent the opening of the filling valve when no bottle is on the rest. Specification 304,267 is referred to.

Title: Improvements in yarn winding machines
IPC: B65H63/036
Filed: 1943-09-15
Abstract: 569,765. Winding yarns. ARUNDEL, COULTHARD, & CO., Ltd., and RIDGWAY, F. Sept. 15, 1943, No. 15137. [Class 120 (ii)] In a drum-winding machine a one-way clutch k, q, Fig. 1, is provided between the handle f by which the package is manipulated and a. part j on the cradle d carrying the package a which, when the handle has been moved to lower the cradle on to its drum, allows the said part to move freely without moving the handle while the package builds up and when the handle is moved to raise the package from the drum. e.g. at knock-off grips the part j and moves the package to a predetermined distance from the drum, the arrangement allowing the cradle to rise as the package increases in diameter without altering the distance which the periphery of the package is raised from its driving drum at knock-off. The handle f is attached by a bellcrank lever g pivoted at h to a dashpot cylinder i, the plunger j of which is attached to the cradle d and passes through a spring-loaded collet type clutch k, the flange k<1> on which the spring m bears normally engaging an abutment rod n, Fig. 2. resting by the adjustable screw o on the rail p. In operation when the handle f falls it raises the dash-pot cylinder i, Fig. 1, and closes the collet k on the plunger j and so raises the latter with the cradle d and package a. When the handle is raised to restart the machine the cylinder i and plunger are lowered until the yarn package engages the driving drum b. Further movement causes the flange k<1> to engage the rod n which withdraws the collet from the conical recess in the cap q and leaves the plunger j free so that the yarn package can lift freely as it increases in diameter. Instead of a dash-pot the bell-crank lever g can be coupled directly to a part having a conical recess to receive the collet around a rod coupled to the cradle d. The collet is spring- loaded. Alternatively a spring-loaded wedge may be used instead of a collet.

Abstract: 560,266. Driving gear. WILKINSON, A. R. J., and RICHARDSON, E. Oct. 30, 1942, No. 15262. [Class 7 (ii)] [Also in Group XXVI] In an engine-driving mechanism comprising an eccentric 5 rotating in a housing 9 slidable in a frame 12 connected to the pistons 15, the eccentric projects from one face of a fly-wheel which has a recess of equal volume in its opposite face. Two such fly-wheels may be mounted on the same shaft with the eccentrics displaced by 180 degrees or in the case of steam engines by 30 degrees. The eccentrics are engaged by pairs of shoes 16, 17 and 18, 19 hinged to links 27, 28 pivoted at 29, 30 to the housing and subjected alternately to oil pressure supplied to pistons 31, 32. The oil is supplied through passages in the shaft and eccentric to reservoirs 43, 44 between the shoes and thence to chambers 34, 35 formed between the housing 9 and frame 12. Relative movement of the members 9, 12 varies the volume of the chambers thereby increasing or decreasing the pressure on the shoes. When the pistons 5 move to the left pressure is applied to the piston 31 and thence to the shoe 16, shoe 17 being lifted by the link 27 from contact with the eccentric ; chamber 34 being vented at the same time. On the return stroke, chamber 35 is vented and pressure applied to piston 82.

Abstract: 672,256. Valve amplifying circuits. COMMUNICATIONS PATENTS, Ltd. June 8, 1950 [June 9, 1949], No. 15415/49. Class 40 (vi). In a push-pull amplifier two or more stages which are similarly phased in respect of in-phase voltage variations are connected in series across the H.T. supply, so that negative feed-back occurs in respect of in-phase signals: As applied to a three-stage amplifier the first stage, comprising a double-triode 4 provided with anode load resistances 13, 14, is connected in series with the third stage which also comprises a double triode, 6. Unbalanced signals are applied via terminals 10 to one grid of the valve 4, the other grid being earthed and a balanced output being obtained by means of a common cathode resistance 12. The anodes of the valve 4 are directly connected to the grids of the second stage, which comprises a further doubletriode 5 with a common cathode resistance 19 and anode loads 20, 21. The final stage 6 is also provided with a common cathode resistance 15 and the grids are directly connected to the anodes of the valve 5; anode load resistances 16, 17 are provided, a push-pull output being obtained at the terminals 18. Additional negative feed-back may be obtained by connection of one or other anode of the stage 6 to the corresponding grid of the stage 4, via resistances 25, 27 and D.C. blocking condensers 26, 28. The arrangement is balanced by means of an adjustable potentiometer 11 connected between the cathodes of the valve 4; the state of balance is indicated by a centre-zero meter 22 which may be connected between the anodes of the valve 6. In a modification, Fig. 2 (not shown), the first stage of the amplifier comprises a pair of pentodes and balance is adjusted by means of a potentiometer connected between the screens of the valves, and whose slider is connected to a further potentiometer across the H.T. supply whereby the total current may be adjusted. In this embodiment the output stage works into a push-pull transformer arranged in its cathode circuit and requires an anode current exceeding that of the preceding valves in the series chain, the excess current being by-passed over a resistance which is connected to a tap on the H.T. supply.

Title: Improvements in systems of control for electrical apparatus
IPC: H03F1/54
Filed: 1949-06-15
Abstract: 672,931. Valve circuits; radio signalling. GENERAL ELECTRIC CO., Ltd., and NETTLESHIP, T. G. P. May 3, 1950 [June 15, 1949], No. 15963/49. Classes 40 (v) and 40 (vi). A control apparatus for a pair of valve devices and a pair of power units therefor comprises manually operated switches whereby either valve device may be brought into service with either power unit and automatic means for changing over to the spare valve device or power unit on the occurrence of a fault. The circuit shown is associated with two receiver-amplifiers (A and B, not shown), and two power units (A and B, not shown) of a radio relay link. To bring the A units into operation non-locking keys ARK and APK are depressed to ensure that relays R and P are released, and switch SK is then operated. This operates relay S, the contacts of which operate relays ACH and BCH respectively, switching on the filaments of the amplifiers. When the filaments have warmed up relays ACD and BCD operate. Contact ACD1 operates relay AH which connects the full H.T. to amplifier A and contact BCD2 operates relay BL which connects a low H.T. to amplifier B to prevent the valves from deteriorating. Contact ACD1 also operates relay AW which connects the input and output lines to amplifier A. To change over to amplifier B switch BRK is momentarily operated, operating a main controlling relay R which locks in. Contact R2 moves the input and output lines to amplifier B by operating relay BW and releasing relay AW. Contact R3 in changing over does not alter the condition of the low power switching relays AL and BL since delay contact ACD2 has already operated but contacts R4 and R5 release relay S and operate relay C causing power unit A to be connected to amplifier B and vice versa, by means of contacts, not shown. A similar change-over would have occurred if a fault had developed in amplifier A for this would have caused the fault relay ALF to operate and its contact ALF1 to operate relay R as before. Contact ALF2, however, releases relay ACH and thus switches off the filaments of amplifier A. A further contact could be provided to operate an alarm. The S and C contacts ensure that the correct power unit is switched off even though the A and B units may be cross-connected. The changeover of power units on the occurrence of a fault or manually is effected by fault relays APF and BPF or switch BPK and by relay P operating in a similar manner to relay R. It is stated that the change-over of input and output lines of the amplifier alternatively could be effected by contacts or relays S and C.
