Title: Improvements in and relating to wicks
IPC: F21V37/00
Filed: 1924-09-26
Abstract: 249,571. Miles, F. D., and Nobel's Explosives Co., Ltd. Sept. 26, 1924. Wicks. -Lamp wicks are tendered preferably by treatment with hydrochloric, nitric, or other suitable acid and are then reinforced or stiffened by a substance which is unaffected by the fuel, does not soften on heating or leave a solid residue on burning. For example, a cotton wick after being freed from grease is dipped into a 20 per cent solution of hydrochloric acid. The excess acid is allowed to drain away and the wick is dried in an oven at about 80 to 100‹ C. When dry it is soaked in an ammonia solution of about 5 per cent concentration and again dried. It is then stiffened by applying a 5 per cent solution of nitrocellulose in acetone by means of a brush and again dried. The Provisional Specification states that wicks may be treated with nitrocellulose without having first been tendered. It also states that acetyl-cellulose or other cellulose derivatives may be used in place of nitrocellulose.

Title: Improvements in or relating to the recovery of beryllium values
Inventor: DERRY RAYMOND
IPC: C22B35/00
Filed: 1961-06-28
Abstract: Beryllium values are recovered from beryl ores by fusion of the ore in the absence of additives, controlled cooling such as to cause recrystallization of the beryllia, treatment with sulphuric acid at an elevated temperature and leaching with water.  The process gives selective extraction of beryllium relative to aluminium, and may be effected by heating the ore in a graphite crucible in an induction furnace, which is switched off for cooling.  For high-grade ores, i.e. 10-12% (by weight) beryllia, the cooling rate is exponential with a value of 80 DEG  C. per minute at 1700 DEG  C.  For low-grade ores, i.e. 2-4% BeO a linear cooling rate of 2.5 DEG  C. per minute to 900 DEG  C. is used.  Treatment of the cooled material with H2SO4 is carried out at 250-300 DEG  C. and leaching may be with hot water. The cooled fused ore may be reheated, before sulphating, at 900 DEG to 1000 DEG  C.

Abstract: 419,282. Testing balance of rotary bodies. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 14, 1934, No. 23447. Convention date, Aug. 14, 1933. [Class 106 (ii).] Comprises a method and apparatus having compensating weights movably arranged around the testing axis within a balance head, in which at each end of the shaft of the test body a balancing head is provided, so that both heads can be operated simultaneously. Balancing heads 4, 5 are mounted on the shaft ends 2, 3 of the body 1 by means of clamping jaws 6, 7. These may be provided with, in known manner, clamping sleeves 8 for different shaft diameters. On the journals 10 of the clamping jaws the heads 4, 5 are mounted which at the same time form supports for ball bearings 14, 15 mounted on journals 12. Each head consists of a casing 16 having a part cylindrical and part conical track for two steel balls 18 which are held in position by a conical sleeve 20 acted upon by a spring 21 bearing against a ring 23 secured by a pin 22 passing through a slot 24 in the journal 19. The sleeve is formed with a riveted pivot 25 on which a handle 26 is rotatably mounted. A scale ring 27 is rotatably mounted on the casing. Two displaceable bearing supports 30 are mounted on a foundation frame 28 and each carries a resiliently held bearing saddle 31 fixed by a vertical supporting spring 33 and two lateral guide springs 35 adjustable by screws 32 and 34 respectively. The outer rings of the ball bearings 14 are inserted in the saddles 31 and are prevented from longitudinal displacement by forked guides 37. Before inserting the body in the saddle 31 the driving belt 38 must be placed in position and tensioned by moving the motor 39 bodily by a screw 42. The heads 4, 5 are first fastened to the body and the unit placed in the supports 30, the belt being adjusted and the motor started. When the first critical speed is reached, the handles 26 are drawn apart by hand or electromagnetically. The balls 28 then adjust themselves so that the axis of inertia of the body coincides with that of the rotary bearing axis so that vibrations disappear. The position of the out-of-balance can be determined in known manner using the scale 27.

Title: Improvements in transformer "on-load" tap changing mechanisms
IPC: H01F29/04
Filed: 1932-08-22
Abstract: 406,050. Transformers. JOHNSON & PHILLIPS, Ltd., Victoria Works, Charlton, and BLOOME, J., 20, Glenluce Road, Westcombe Park, both in London. Aug. 22, 1932, No. 23465. [Class 38 (ii).] An " on load " tap-changing arrangement comprises tap contacts s1 . s4 and strip contacts k1, k2 with which co-operate bridge contacts b, B and an impedance Z provided with contacts p which engage with contacts p1, p2 on the strips k1, k2 but permit it to be bodily removed. To effect a change of tap connection (e.g. from l1 to l2) the impedance Z is first connected across the contact strips k1, k2. The sliding bridge contacts are then moved so that b breaks contact with the contact s1 and engages the contact s<2>, the voltage difference between the two tappings being absorbed by the impedance Z. Further movement brings the bridge contact B into contact with the tap contact s2. to complete the change. The impedance can then be disconnected.

Title: Improvements relating to totalizing apparatus, more especially for storing data, suitable for example for water meters
IPC: G01F15/07
Filed: 1967-05-22
Abstract: 1,143,494. Metering. HERSEY - SPARLING METER CO. 22 May, 1967 [24 May, 1966], No. 23582/67. Headings G4D and G4H. In totalizing apparatus e.g. for metering water flow, the rotation of a member 30 (Fig. 2) at a rate proprotional to the speed of flow controls a counter 106, cam wheels rotating with the counter wheels operating switches to give an electrical read-out of the state of the counter. In the embodiment described rotation of gear 30 results in a lug 78 on a gear 72 (Fig. 17) being rotated to contact either lobe 90 or 92 (depending on its direction of rotation). This results in an actuator 80 being rotated to bring either lobe 84 or 86 against a cam surface 100 to drive arm 94 so that a lug 108 rides up the slopes (Fig. 4) of a gear 110 connected to the lowest decade wheel. When lobe 84 or 86 drops out of contact with cam surface 100, spring 112 forces arm 94 towards a spindle so that load 84 or 86 is advanced one digital position. Consequently wheel 122 advances one unit for 180 degrees rotation of gear 72. Transfer between decades occurs when a gear 142 engages a pinion 148 connected to the gear 132 of the next higher decade wheel assembly. Connected to each of the four decade wheels of the counter are four binary coded cams 134, 136, 138, 140 which depress associated brushes 162 against a rail 170 to give an electrical read-out of the state of the counter in binary coded decimal form. If a continuous read-out is not required the rail 170 may be brought into contact with the brushes when read-out is desired by actuation of a solenoid.

Abstract: 825,523. Bread, extracting from baking tins. BAKER PERKINS Ltd. Jan. 23, 1956, No. 23654/58. Divided out of 825,522. Class 28 (1). [Also in Group XXX] In a bread detinning machine, the tins are received in rows on one or more radial platforms of a rotary device where they are clamped by arm means extending radially from the centre of the device and acting normally on the platform or platforms and the rotary device is driven to invert the tins and discharge the loaves by gravity. As shown, a pusher gear 1 driven from a motor 15 advances bread tins 2, preferably grouped by straps 3, from a conveyer over a surface 5 to the detinning mechanism 6 driven through chain 16 by the motor 15. This mechanism comprises a shaft 7 carrying two tin-receiving platforms 8 rotated in time with gear 1 from motor 15 so that a platform 8 arrives at loading point A as a load of tins slides from ramp 10. The tins are held on the platforms 8 by clamping arms 11 secured to actuating shafts 12 parallel to the axis of shaft 7. A crank 13 at the end of each shaft 12 carries a roller 14 at its outer end engageable in a box cam contoured so as to cause arms 11 to clamp a row of tins on each platform 8 as it leaves loading point A and to unclamp at an empty tin release station C where the tins slide off down a slope 20 on to a conveyer 21. The loaves may be deposited, inverted, on a conveyer or may be righted as described in Specfication 825,522.

Title: Control circuit
IPC: H05B41/04
Filed: 1969-05-09
Abstract: 1,255,532. Control systems for gas discharge lamps. RCA CORPORATION. 9 May, 1969 [14 May, 1968], No. 23722/69. Heading H2H.  A control system for a load such as a gas discharge lamp comprises means whereby the lamp may be restarted when hot, should the lamp become extinguished, with a minimum of delay. A mercury vapour lamp 10 is supplied from a D.C. ballast circuit 16 over serially connected primary and secondary windings 22, 24 of a transformer, the circuit 16 providing a voltage which is sufficiently high to start a lamp having a starting electrode when cold but which is insufficiently high to start a lamp without a starting electrode when cold. Furthermore the ballast circuit 16 does not provide a voltage high enough to restart either type of lamp when hot after the lamp has been extinguished. To provide an additional voltage a starting circuit 26 is provided. With the lamp 10 extinguished the high voltage output from the ballast circuit 16 is applied to a potential divider 28, 30 and charges a capacitor 48 by way of a resistor 46 and winding 22. This high voltage is sufficient to produce a voltage between resistors 28, 30 to break down a gas filled tube 32 to charge a capacitor 36. When the voltage across the capacitor 36 reaches a certain value a unijunction transistor 38 becomes conductive thereby to provide a signal to trigger a thyristor 44 into conduction. Capacitor 48 then discharges through the winding 22 thus inducing a voltage in winding 24 which is added to the output voltage of the ballast circuit 16. The unijunction transistor 38 and the capacitor 36 function as a multivibrator providing a series of pulses to the trigger electrode of the thyristor 44 whereby the secondary winding 24 provides a series of injected voltages until the lamp 10 starts or restarts. After the lamp has started or restarted the output voltage of the ballast circuit 16 drops to the running voltage of the lamp 10 and the starting circuit 26 becomes ineffective.
