Title: Improvements in and relating to machines for applying capsules to bottles
Inventor: HAMILTON THOMAS
IPC: B67B5/00
Filed: 1954-10-20
Abstract: 782,366. Capsuling bottles. WALKER & SONS, Ltd., J. Oct. 19 1955 [Oct. 20 1954], No. 30222/54. Class 125(2).. Relates to apparatus for applying capsules to corked bottles which are fed by a conveyer 65 to platforms 44 which are then raised so that the bottle necks with capsules loose thereon enter cups in a sealing head 17, the cups being deformed to tighten the capsules by hydraulic pressure whereupon the platforms are lowered and the bottles are removed by a delivering conveyer 66. According to the invention, the bottles are fed on to the platforms 44 by fingers 64 on an intermittentlv driven endless chain 63 driven from a continuously rotated shaft 33 by the mechanism described below. Shaft 33, through bevel gearing 47, drives a vertical shaft 48 the top of which carries a cam 49 having on its underside a pawl 50 driving a cog wheel 51. This drives the sprocket 57 of chain 63 through gears 54, 55 but periodically pawl 50 is disengaged to stop the chain by a fixed cam 52 and at the same time the cam 49 pivots a lever 59, Fig. 7, a projection 61 on which locks the teeth of gear 55. The other sprocket 62 of chain 63, through gearing 71, 72 rotates intermittently a star wheel 75 overlying the feed conveyer 65 to space the bottles. The bottles pass between guides 76, 77 the latter of which carries spring-loaded bottle-locating fingers 78. If the bottles be square in crosssection, guide 76 carries spring- loaded fingers 82 which prevent their rotating during capsuling. Shaft 33, which is driven by a continuously-running electric motor 22, also intermittently operates a valve 20 causing actuation of the capsuling cups and, through a cam 34, raises the bottle platforms 44 which are counterweighted and spring-loaded. The head 17 may be vertically adjustable to suit different bottle heights and the star-wheel 75 can be swung across the conveyer 65 to deal with bottles of varying diameter.

Title: Improvements in or relating to gramophones or the like
IPC: G11B25/04
Filed: 1938-10-19
Abstract: 520,356. Phonographs. WEBSTER ELECTRIC CO. Oct. 19, 1938, No. 30263. Convention date, Feb. 18. [Class 40 (ii)] In a phonograph contained in a casing 21, Fig. 1, provided with a lid 22 the pickup arm 35 is mounted between a plate 50 and the lid, and when the lid is opened the pick-up is first lifted and then returned by gravity to the starting position. In the form shown, the plate 50 is fastened to the lid by screws 51 passing through fibre bushes 52, Fig. 4, which space the plate away from the lid. In Fig. 4, the lid is omitted to show the pick-up from above over the beginning of a ten-inch record 34. The pick-up arm 35 is pivotally mounted at 55, the mounting comprising a rotatable post 72 with which pivot pins 66, 67 engage, so that universal movement of the pick-up when in use is permitted. In order to facilitate the setting of the pick-up arm to the proper starting positions for records of different sizes, there is provided an adjustable stop 85 comprising a pin 87 surrounded by a rubber sleeve and carried by a lever 88 pivoted at 92 on the plate 50. The pin 87 passes through a slot 98 in the plate 50, so that it is adapted to be engaged by a flange 102 on the pick-up arm. When the pin 87 is at one end of the slot, as shown in Fig. 4, and the flange 102 is in contact therewith, the pick-up is in position for starting a ten-inch record ; when the lever is moved to bring the pin to the other end of the slot, it determines the proper position for starting a twelve-inch record. Intermediate settings of the lever 88 may be provided for, to suit records of other sizes. A rubber stud 107 having a rounded point adapted to engage in either of two holes 110, 112 in the plate 50, is preferably mounted in the pick-up arm 35. A wire spring 113 may be coiled round a screw 115 on the pick-up arm so that its free end can engage the stop 85. When the lid is lowered (the pick-up arm having been set in contact with the stop pin 87, previously adjusted in accordance with the size of a record on the turntable), the point of the stud 107, if this is provided, first enters one of the holes 110, 112 and steadies the pick-up arm on the plate 50. Then, as the lid is fully closed, the needle rests on the smooth margin of the record, the pick-up arm is raised slightly so that the point of the stud 107 is lifted from the hole, and the spring 113 impels the needle into the sound-groove. The provision of the stud 107 for accurately positioning the pick-up and of the spring 113, is unnecessary if the records used have outer leading-in grooves. To repeat the playing of a record, it is only necessary to raise the lid sufficiently for the pick-up arm to swing back against the stop-pin 87 and then to close it. The turntable hub is supported by a rubber washer over a flange on the driving shaft 26. The pick-up may be constructed as described in Specification 520,357, [Group XXXIX], and is fastened by bolts to flanges on the pick-up arm. The pick-up arm, instead of being carried by the lid, may be carried by a pivotal frame linked to the lid.

Title: Liquid compositions comprising organic titanium compounds
Inventor: EMBLEM HAROLD GARTEN
IPC: C04B33/13
Filed: 1962-08-08
Abstract: A titanium oxide gel is produced by hydrolysing a mixture of an organic titanium extra Ti(ORX)4, where R is an alkylene group having 2-4 carbon atoms and X is Cl, Br or I, and an amino alcohol N(R1)(R2)(R3).  The groups R1, R2, and R3 may be straight chain hydroxyalkyl having 2-5 carbon atoms, or branched chain polyhydroxyalkyl having 4-5 carbon atoms; R1 and R2 may also be hydrogen, or alkyl or aminoalkyl having 1-5 carbon atoms. At least 1/n moles amino alcohol are used per mole of Ti ester, where n is the number of R1, R2 and R3 groups which are hydroxyalkyl. Preferred reagents are titanium tetrabetachloroethoxide, and mono-, di-, or tri-ethanolamine, N-methyl ethanolamine, N-(2-aminoethyl) ethanolamine, or 2-amino-2-ethyl propan-1,3-diol. Hydrolysis may be effected by adding water to the mixture, alone or diluted with e.g. methanol, ethanol, n- and iso-propanol; these solvents may also be included in the mixture.  Refractory articles are produced by adding refractory powder, e.g. zircon or alumina, prior to gelling; then shaping, allowing to gel and harden, and firing.

Abstract: 1351222 Valves A E I OLSSON 29 June 1971 [10 July 1970 23 March 1971] 30389/71 Heading F2V A pressure reducing valve has a piston 5 controlling flow from inlet 2 to outlet 3 via equallength passages 7-9 opened in succession as the piston responds to the pressure difference thereacross acting against spring 6. When flow from the outlet is arrested, pressure equalizes across the piston, due to leakage around the piston or through a by-pass, and spring 6 returns the piston to its closed position. The passages 7-9 may alternatively be formed by grooves and may be provided in the piston rather than in the housing. In Fig. 5, flow takes place through passages 29-31 in an inner piston 14 surrounded by outer piston 13, the pistons being spring- biased at 24, 15 respectively, but piston 13 responding to a given change in 'the inlet-outlet pressure differential by moving a greater distance than piston 14. Restrictor 19 controlling admission to and from chamber 18 damps the response of piston 13. In Fig. 6, not shown, outlet fluid has unrestricted access to chamber 18 and piston 14 is biased by bellows (26) which replaces or supplements spring 24 and damps response of piston 14.

Abstract: 1,116,493. Packaging-machines; bitumen package. MINERAHOL- u ASPHALTWERKE A.G. 16 July, 1965 [20 April, 1965], No. 30396/65. Heading B8C. Bitumen is packaged by being poured molten into plastics bags at a temperature below that to which it is heated for use, the bags being arranged in moulds and their mouths pressed on to the contents while it is still hot. The bags may be of a material, e.g. polypropylene, which will melt at the use temperature, enabling the bag to remain on the contents during melting. The bag may be white to reduce the effect of exposure to the sun. Apparatus for producing blocks comprises rows of moulds 2 on a conveyer 1 moving intermittently from a station where bags are inserted, past filling means 3 (not shown), to a position where the solidified blocks fall on a resilient shoot member 13 and on to a conveyer 14 for removal to a discharge table 15. Each mould has a false bottom and this is raised towards the mouth by a piston-rod 11 to eject any block not falling out by gravity. Alternatively, a compressed air nozzle may engage an aperture in the mould base (not shown).

Title: Improved process for the production of sodium pentaborate direct from boron ores
IPC: C01B35/10
Filed: 1924-12-18
Abstract: Sodium pentaborate is obtained by treating a boron ore such as boronatrocalcite with sulphur dioxide until the bulk of the ore is saturated, then adding a calculated quantity of untreated ore and heating the whole in water preferably with the addition of a small quantity of sodium sulphate to increase the yield.  If the quantity of sulphur dioxide absorbed by the ore is just sufficient to saturate the calcium contained in it, no addition of untreated ore is necessary.

Filed: 1965-07-19
Abstract: 1,115,602. Transistor switching circuits. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 18 July, 1966 [19 July, 1965], No. 30607/65. Heading H3T. [Also in Division G4] A timing circuit for a road traffic signal system comprises a capacitor C forming a Miller integrator circuit with transistors VT2 and VT3. When a contact S1 is closed a step voltage is applied to the base of VT2 causing the capacitor C to discharge until VT4 conducts and operates relay RR. The period timed can be varied by varying the step voltage by adjustment of the resistance RS in the emitter circuit of VT1. If contact S2 is closed the timing circuit is held in its existing state until the contact is re-opened. A Zener diode D6 stabilizes the power supply and diodes D1-D4 compensate for temperature variations. The contacts S1 and S2 may be replaced by transistors (VT7 and VT6 in Fig. 4, not shown).

Patent GB-1399979-A (GB)
Title: Stencil cutting
IPC: B41C1/14
Filed: 1973-06-28
Abstract: 1399979 Electronic stencil cutter INSTRUMENT CORP OF AMERICA 28 June 1973 [5 July 1972] 30900/73 Heading H4F Facsimile-type stencil cutting is effected by producing a train of pulses having widths inversely proportional to the intensity of a photoelectrically scanned original, and using a power amplifier to convert these pulses into current pulses which are applied to a spark producing stylus, the current pulses having periods inversely proportional to the intensity of the original. Thus the density of the pattern on the stencil is inversely proportional to the intensity of the original. In the embodiment described the original is analysed by a photomultiplier 8 and capacitor 28, which comprises the stray capacitance of the photomultiplier lead, is charged. An oscillator 22 and a switching transistor Q1 are connected to terminal 24. When the oscillator 22 switches from a first state to a second state, Fig. 3A, the voltage at terminal 24 is increased as shown in Fig. 3B. As photomultiplier 8 draws current as a function of the intensity of the original, capacitance 28 is charged in the negative direction as shown in Fig. 3B, and when the voltage across the capacitance reaches - Vc at point A1 the capacitance is fully charged which causes transistor Q1 to turn ON as shown in Fig. 3C. Points A2 and A3 in Fig. 3B, are representative of high and low intensity portions of the original. Thus it can be seen that the OFF period of the switching transistor Q1 is inversely proportional to the amount of current through the photomultiplier i.e. inversely proportional to the pattern on the original. Variable resistance 30 comprises a black level control. If a resistor 25 is connected as shown the charging curve of capacitance 28 is modified from a straight line as shown in Fig. 3B, to an exponential curve so that the inverse proportionality is changed to logarithmic. Gate 32 prevents the OFF period t, Fig. 3C, of the switching transistor Q1 exceeding 50% of the period of the oscillator 22 i.e. T in Fig. 3A. Positive-negative switch 36 enables the image of the original produced on the stencil to be reversed. Start/stop circuit 40 functions to start and stop the stencil cutter and to interrupt the stylus current when the stylus crosses a paper hold-down clamp, and includes lightresponsive transistor Q7. As described the original and stencil are mounted on a rotating drum.

Title: Improvements in or relating to staircase waveform generator circuits
Inventor: HURR ERNEST ROY
IPC: H03K4/02
Filed: 1958-09-29
Abstract: 876,376. Valve pulse generating circuits. BUSH & RANK CINTEL Ltd. Sept. 28, 1959 [Sept. 29, 1958], No. 31039/58. Class 40(6) The Specification relates to staircase waveform generators of the type in which the charge on a capacitor 10 is transferred in steps to a second capacitor 12. As shown, valve 3 is normally cut off by bias from potentiometer 9 so that the anode is at the potential of the slider of potentiometer 5. Each positive input pulse A drives valve 3 into conduction, discharging capacitor 10 until the anode voltage falls to 250V when the discharge is terminated by the catching diode 7 as shown at B. Capacitor 12 is charged negatively via diode 11 by an amount dependent on the relative capacitance of the two capacitors and adjustable by variable resistor 5. At the end of each pulse A, capacitor 12 retains its new voltage as shown at C. Subsequent pulses A reduce the voltage of capacitor 12 by equal steps. The staircase waveform C is fed via the cathode follower 13 and a D.C. restorer 17 to an output terminal 16. The cathode of diode 11 is clamped to valve 13 cathode potential by diode 19 at the end of each pulse A thus preventing change of voltage of capacitor 12. The staircase waveform is also inverted by valve 25. When the voltage at the anode of valve 25 has reached a value corresponding to the desired amplitude of staircase waveform, valve 29 conducts, cutting-off valve 31 to provide a step D which is fed via a cathode follower 39 to drive diode 42 into conduction, causing diode 43 to discharge capacitor 12 in readiness for the next pulse A. A positive inhibiting voltage may be applied via terminal 44 and diode 45. Specification 876,377 is referred to.

Title: A process for the manufacture of acid anhydrides
IPC: C07C51/54
Filed: 1932-11-03
Abstract: Mixed anhydrides are obtained by reacting a ketene with a carboxylic acid with a different number of carbon atoms, and the mixed anhydrides are then heated to rearrange the molecule into the anhydrides of the separate acids.  Ketene or a body of the type R = CO where R is a divalent hydrocarbon radical or a substitution product thereof is reacted in liquid or preferably gaseous state and may be pure or admixed with diluents such as methane, ethylene, carbon oxides, air and the like.  In the gaseous form the ketene may be scrubbed with the liquid acid at ordinary temperature and pressure.  The mixed anhydride is then decomposed by heating in a still fitted with a fractionating column and a reflux condenser, so that only the lower boiling anhydride is removed as distillate. Examples describe the reaction of ketene with butyric and propionic acids and the decomposition of the mixed anhydrides.  Other acids which are stated to be suitable are acrylic, propiolic, isocrotonic, cinnamic, phenylpropiolic, benzylmalonic, phenylacetic, benzoic, toluic, and naphthoic acids.  In the case of benzylmalonic acid two molecules of ketene react with one of the acid to produce the mixed anhydride, which on decomposition yields benzylmalonic and acetic anhydrides.
