Title: Improvements relating to the manufacture of glass bottles and jars and like containers
IPC: B08B9/38
Filed: 1938-01-26
Abstract: 504,485. Removing adherent fragments &c. from glass containers. CANNING TOWN GLASS WORKS, Ltd., and PARNABY, J. J. Jan. 26, 1938, No. 2498. [Class 60] Adherent fragments or particles of glass are removed from glass bottles, jars and containers by means of chains &c. 1 carried by a head 3 on a rotating spindle 4, or by the spindle itself, the chains moving outwards under centrifugal force so as to wipe across the whole inner surface of the bottle &c. as this is moved axially by the spindle. The spindle may be screwed at 5 to enter adjustably a screwed chuck 7 driven by a pulley 18 and running in ball bearings 13 carried by a table 9, 10, or the spindle may be tapered or squared to enter the chuck, or the chuck may be of the clamp jaw type. The table carries a support 14 on which is a rubber, &c. pad 17, a shield 16 surrounding the chuck 7, and in operation, the container 19 is moved down to reach the pad and is then lifted. The chains 1 may be of flat form to lie close to the spindle, or the spindle may be grooved to receive the chains so as to pass through a narrow neck of a bottle. In order to treat the inner bottom corners of convex bottomed containers, the chains are replaced by a coil spring or springs extending outward from the end of the spindle and upwards at an obtuse angle to the spindle axis. In place of the chains, weights or bobs attached to flexible wires may be used.

Title: Improvements in and relating to synthetic resinous products from furfuryl alcohol
IPC: C08G65/36
Filed: 1943-02-17
Abstract: Liquid resinous products are obtained by heating furfuryl alcohol in presence of an organic compound, containing chlorine in an alkyl radical and capable of slowly liberating hydrogen chloride on heating for a period sufficient to initiate resinification of the furfuryl alcohol but insufficient to cause the reaction product to solidify. Chlorine compounds specified are chlorinated rubber, chlorinated kerosene, tetrachlorotoluol, benzal chloride, chlorinated triisobutylene, chlorinated turpentine, chlorinated aliphatic alcohols, e.g. a -dichlorhydrin, 2-chloro-allyl alcohol, b -chloroethyl benzyl alcohol, phenyl ethylene chlorhydrin, chlorocyclohexanol, chlorinated stearic, toluic, or abietic acids; chlorinated ketones and aldehydes, chlorinated alkyl esters; chlorinated tricresyl phosphate or butyl carbonate.  The liquid resin may be converted to the infusible state by heating at 75-150 DEG  C., preferably in presence of plaster of paris or like water absorbent. With the addition of driers, it may be used to replace drying oils. The Specification contains a long list of fillers, compounders and plasticisers which may be added.  In examples, 100 parts furfuryl alcohol are reacted (1) with one part of chlorinated tricresyl phosphate; (2) with methyl trichlorostearate; (3) with chlorinated triisobutylene; (4) with a -dichlor hydrin; (7) with 2-chlor allyl alcohol.  Specifications 547,854 and 549,515 are referred to.
Patent GB-294916-A (GB)
Title: Improvements in or relating to coin-freed apparatus
Filed: 1927-01-29
Abstract: 294,916. Brecknell, Munro, & Rogers, Ltd., and Plaskett, A. F. G. Jan. 29, 1927. Magnetic separators.-Means are provided in coin-freed appa ratus for differentiating between coins made of material having a predetermined electro-value and those of material having another electro-value, and for preventing the latter coins from operating the apparatus, the electro-value being the electrical potential of the coin relative to an electrode when the coin and electrode are both in contact with an electrolvte. A coin 16 inserted in a shoot 2, Fig. 1, makes contact with a spring 15 and with a wick 10 lying along a zinc strip 8, the wick being moistened by potassium chloride solution contained in a vessel 6. The strip 8 and the shoot are connected by wires 17, 19 to slip rings 18, 20 of an armature 12 which rotates or rocks in the field of a magnet 11. When a silver coin is inserted, the current generated is sufficient to cause a stop 14 carried by the armature 12 to be projected into the shoot 2 so that the coin will roll along a branch 4 to release the apparatus. The current generated by a copper coin is insufficient to move the stop into the shoot and such a coin drops down a shoot 3 and may be returned to the purchaser. The armature is counterbalanced, and the stop 14 is withdrawn from the shoot 2 when the delivery drawer or the like is actuated. In the modification, Fig. 5, the coin is pressed and held against the substance containing the electrolyte. The coin drops to a slotway 26 in a carrier 27 haying an axle 28 pivoted in a bracket 29, the coin being retained by the bent end 35 of a member 36 loosely mounted on the axle and retained in position by a spring 37. When the coin is inserted, a rod 45 is pulled to move a lever 44 loose on the axle 28 but connected to the carrier 27 by a spring 46. The lever 44 rocks the carrier to press the coin against an electrode 50 covered by a wick 52 containing the electrolyte. The member 36 is also rocked by studs 47, 48. Continued movement of the lever 44 causes the member 36 to uncover the slotway 26 and to be retained in this position by a detent 40 engaging a shoulder 39. When a spring 53 returns the lever 44, the carrier 27 is returned by a portion 54 of the lever, so that the coin drops. At the end of its return movement, a nose 56 on the lever 44 engages an arm 43 on the pivot 41 of the detent 40, thereby raising the detent and allowing the member 36 to be returned by the spring 37. The diverting means may be arranged as shown in Fig. 8 in which a stop 14 for the coin shoot is mounted on a lever 57 comprising the armature of an electromagnet 60 energized by the current set up by the coin in contact with the electrolyte.

Title: Improvements in or relating to decorative lighting arrangements incorporating electric discharge lamps
IPC: H05B41/40
Filed: 1951-02-02
Abstract: 708,918. Switching systems for space discharge apparatus. GENERAL ELECTRIC CO., Ltd., and WILLIAMS, C. E. Dec. 13, 1951 [Feb. 2, 1951], No. 2665/51. ,Class 38(4) An arrangement for obtaining variable lighting effects from two or more sets of electric discharge lamps, each set giving light of different colour and/or having different spatial distribution, comprises a non- linear dimmer impedance R engaged between its ends A, D by the spaced bridged contacts 6, 7 of a wiper 5 connected into the lamp operating circuit and having connected to either end A, D the lamp sets to be lit, whereby wiper movement from either end of the impedance to the other dims one lamp set and brightens the other by corresponding amounts, the non-linear characteristic of the impedance R compensating the non-linear characteristic of the lamps to yield constant total light output. In the case of two-lamp sets, they are connected directly to the impedance ends A, D, but in the case of three-lamp sets 17 ... 19, as shown, they are connected sequentially when unlit by two-ganged six-contact makebefore-break rotary switches 13, 14 having contact arms 20, 21 connected to the impedance ends A, D and actuated simultaneously by the wiper 5 when at the end of its travel in either direction. As shown, e.g. a red neon lamp set 19 and a blue mercury vapour lamp set 18 are operating at 50 per cent brightness, but wiper movement to the right would fully light set 19, fully dim set 18, and actuate switch arms 20, 21 to make contacts 13.2, 14.2 to disconnect set 18 and connect in the dim condition a green mercury vapour lamp set 17. The lamps, of either the hot or cold cathode type, are supplied through tandem connected stray-field transformers 23 and the dimming means from supply lines 15, 25. A shunting resistor 16 compensates for the different dimming impedance characteristic required for the neon lamps as compared with that for mercury vapour lamps. The dimming impedance may be an inductor, or, as shown, a resistor comprising a number of individual resistors whose terminations are connected to the wiper contact studs.

Title: Improvements in or relating to the recovery of cephalosporin c
Inventor: ABRAHAM EDWARD PENLEY
IPC: B01J47/00
Filed: 1960-01-25
Abstract: Cephalosporin C is recovered from a clarified beer containing it and co-present Cephalosporin N by lowering the pH of the clarified beer preferably adjusted to pH5-6 with acetic acid or sodium hydroxide by treatment with a cation exchange material containing strong acidic groups in hydrogen form to a value of from 2.8 to 4.0, separating the cation exchange material from the acidified medium, then passing the acidified medium through a strong anion exchange material in the form of a salt of a weak monobasic organic acid e.g. acetic acid to remove substantially all chloride and other inorganic anions therefrom and thereafter separating the Cephalosporin C from the percolate. The Cephalosporin C may be separated from the percolate by contacting it with an anion exchange material in the form of a salt of a weak monobasic organic acid e.g. acetic acid to adsorb the Cephalosporin C thereon and eluting the adsorbed Cephalosporin C therefrom with acetic or formic acid which, in the case where the anion exchange material is a weak anion exchange material is buffered by the addition of a weak base which is volatile enough to be removed by distillation in vacuo from aqueous solution at a temperature below the decomposition temperature of Cephalosporin C e.g. pyridine or ammonia.  The Cephalosporin C may be precipitated from the eluate by acetone, dissolved in water and converted to its sodium salt by treatment with sodium hydroxide or a strong cation exchange resin in sodium form. The removal of chloride and other anions may be effected by a plurality of sections of strong anion exchange material.  The Cephalosporin C may be separated from the percolate by adsorption on alumina or charcoal and elution therefrom. Specification 810,196 is referred to.

Title: An improved photographic flash device
Inventor: HUTCHISON MILLER REESE
IPC: G03B7/16
Filed: 1962-06-14
Abstract: 968, 932. Photographic flash guns. EASTMAN KODAK CO. June 13, 1963 [June 14, 1962], No. 22844/62. Heading G2A. A photographic flash gun comprises a flashlamp holder connectable to a source, of energization, a switching device in circuit with the holder and source of energization, and a photo-electric device adapted to be illuminated by field light which controls the switching device. As shown, a camera has an optical axis 10 on which are located aperture 12 and shutter blade 14, the blade being actuated by lever 16. A flash bulb 20 mounted in front of reflector 22 is in series with a battery 24, a switch 26, a shutter timing switch 28, and a gated switch 30. The switch 30 may be a silicon rectifier having a gating input 32. A resistor 34 and light dependent resistor 36, e.g., a cadmium sulphide cell is in parallel with bulb 20. Switch 26 is closed by actuation of lever 16 which actuates the shutter which in turn closes switch 28. Should the scene brightness be sufficiently high the resistance of cell 36 is low and switch 30 is non-conducting, thus preventing current flow through the bulb 20 and flash operation. If the scene brightness is low, the resistance of cell 36 is high, such that switch 30 is conducting, thereby permitting current flow through flash bulb 20. In another embodiment, Fig. 3, not shown, a rheostat 44 replaces resistor 34, Fig. 2., and may be adjusted according to a scale 45 of exposure factors.
