The discs are preferably formed of urea-formaldehyde or phenol-formaldehyde artificial resin, and are prepared by compressing, without the action of heat, a mass of the material in powder form, heat and pressure being employed in the final preparation of the seal. Alternatively, the discs may be formed of cellulose acetate, and the seal completed by the action of pressure and a solvent such as acetone.
Patent GB-984473-A (GB)
Title: Improvements relating to the brewing of beer
Inventor: CORRAN HENRY STANLEY
IPC: C12C12/00
Filed: 1962-04-16
Abstract: An acid developed beer for blending with a larger quantity of normal top fermentation beer to produce a developed (fully-matured) beer, is obtained by performing a continuous auxiliary fermentation on normal top fermentation beer by deliberate inoculation with microorganisms such as Lactobacillus (to be predominant), Brettanomyces, Pediococcus, Acetobacter, Torulopsis and Candida, responsible for storage development (maturation) of beer; the beer is passed without turbulence and at a slow rate up through a closed packed vessel filled to capacity with the beer and in which a uniform dispersion of the auxiliary fermentation micro-organisms over the surface of the packing is maintained under minimally aerobic conditions.  The packing may consist of foamed polyurethane, spiral wound metal or plastic textile packing, perforated aluminium or stainless steel discs having rims around the perforations, ceramic rings or perforated trays, and the vessel may be fabricated in glass, ceramic stoneware, aluminium, stainless steel or industrial plastics. The inoculum may be a laboratory culture consisting of Lactobacillus pastorianus and selected species of Brettanomyces, or may be derived from old vats used in storage maturing of beer in which case it will include species of Lactobacillus (principally Lactobacillus pastorianus), Brettanomyces, Pediococcus, and Acetobacter, and may contain Torulopsis and Candida also.  The variable factors available for controlling the auxiliary fermentation are:  rate of throughput of substrate, operating temperature of substrate in the vessel, and the pH, nitrogen content, degree of attenuation, original gravity and oxygen content of the incoming substrate.  In order to produce a blended developed beer having a flavour comparable with that of a normally developed beer, one part of the acid developed beer is blended with from 8 to 12 parts of normal top fermentation beer. The Specification discloses in considerable detail methods of initiating and running the auxiliary fermentation, examples being directed to the auxiliary fermentation of stout with an original gravity of 1073 and a hop content of about 1.0 gram per litre. Substrate used for the inoculum at the initiation of the continuous fermentation preferably has a normal hop content of from 5 to 6 grams per litre.  The packing may be inserted into the vessel after the initiation or if for reason of size &c. it is difficult to insert the packing easily and quickly into the vessel after filling, the fermentation is started with the packing already in position and carbon dioxide is bubbled vigorously through the substrate to ensure uniform dispersal of the micro-organisms. Alternatively a separate, pre-fermenter, vessel without packing may be employed.  Specifications 872,391, 872,392, 872,393, 872,394, 872,395, 872,396, 872,397, 872,398, 872,399 and 872,400 are referred to.

Title: Improvements relating to the manufacture of brushes
IPC: D06M11/45
Filed: 1924-06-17
Abstract: 244,500. Barnett, W., and Barnett, C. June 17, 1924. Bristles, fixing; brush - making machines.-A tuft of bristles is secured in a cup or sleeve A by a drawing operation which reduces the diameter of the cup or sleeve for the full depth of the bristles enclosed. The machine described has tuft - selecting means as described in Specication 245,052, performs also a second drawing-down operation, cuts grooves as shown in Fig. 4 in the sides of the cup, and finally drives the cupped tuft into a hole in a brush-stock. The cups may have a groove spun therein, or may be of a cross-section having sharp corners and be driven into circular holes in the stock. The bristles are fed, as described in the Specification referred to, from a container 30 into a series of notches 40 in a turret Y, each notch being given a forward and backward movement in front of the bristles before being closed, and then a further forward movement followed by a stationary period. These movements are given to the turret by depending pins 45, of which one is always in engagement with a cam P. Each tuft is carried first. over a trimming-knife E driven by a shaft. R, and then over a wheel F operated by a ratchet 22. The cups A are fed by hand or automatic means into holes in the wheel F, and are brought under a tuft and between a die B and an ejector C. Camoperated spring clips close on the end of the tuft and enable the cup to be threaded onto the tuft when the cam-operated ejector C rises. In this movement the die B is carried upwards. The ejector C then remains stationary while the die B is drawn downwards by cams, thus securing the bristles in the cup and giving them a spreading effect. The tuft is then carried to a second drawing-die G preferably of the radial expanding type, to a reciprocating broaching cutter H which cuts the grooves in the sides of the cup, and finally to the tuft-inserter J. The stock is placed against the nozzle 50 with the pilot pin 51 in a hole, and a support then rises to hold the stock. Jaws 52 descend, one engaging a guide 54 and the other passing through and engaging the side of a hole 44 in the turret Y, and grip the tuft. A finger 55 is engaged by the slide J and causes the opening of the tuft-holding notch in the turret, and continued descent of the jaws 52 drives the tuft into the stock, the pilot pin 51 having just previously moved laterally out of the hole.

Abstract: 373,773. Wind-motors. SANKEY, A. R. M., 9, Pyrland Road, Richmond, Surrey. May 19, 1931, No. 14712. [Class 110 (iii).] A wind-wheel A<1> of the transverse flow type is surrounded by a member B carrying pivoted blades B<2> on two opposite segments. On the .windward side the blades lie against stops B<3> and act as directing vanes, whilst on the leeward side they are thrown over to close the segment. The member B is looked in head-to-wind position by a latch E controlled by a wind vane F. The latch engages teeth C<2> on a wheel C which is influenced by wind vanes D, D<1>, the vanes D<1> being pivoted. When the direction of the wind changes the vane F releases. the latch E until the member B has taken up its new head-on position,. when it is again locked. In a modification, Fig. 2, the latch G<1> is actuated by a pivoted vane H to which the wind is directed by vanes J. Further modifications are described. When the wind-wheel is mounted horizontally, the device acts to keep the wheel in the wind.

Title: Improvements in or relating to reservoir pens
IPC: B43K5/04
Filed: 1962-04-17
Abstract: 986,822. Reservoir pens. H. A. A. EXNER. April 17, 1962 [April 18, 1961; June 30, 1961], No. 14728/62. Heading B6P. In a reservoir pen having a retractable writing mechanism, the reservoir contains a compressible flexible capillary material. The capillary material may be compressed with a reciprocating piston type mechanism or the ink reservoir may be of the collapsible type. In the stylographic reservoir pen shown in Fig. 1, the retractable writing mechanism comprises a reservoir 12, a cylindrical guide 18 having capillary grooves 17, Fig. 3, and a nib section 25 screwthreaded into the writing end of the guide 18. The counterweight 22 of the needle 21 is guided in the central bore of the cylindrical guide 18. To fill the pen the headpiece 11 is unscrewed from the barrel 10 of the pen and the complete writing mechanism removed from the barrel. The nib section 25, which has a ribbed or hexagonal section 29 to fit a key 30 in the top of the push button 31 in the headpiece 11, is unscrewed to expose ink openings 27 in the nib section 25. On the downward stroke of the piston 13, the flexible capillary material 16 is compressed and air is expelled from the reservoir through the channels 17, radial capillary channels 24 in a member 19 and the ink openings 27. On the return stroke of the piston 13, ink is drawn into the reservoir through the ink openings 27. The nib section 25 is screwed home into the cylindrical guide 18 and the writing mechanism, pen-barrel 10 and head piece 11 reassembled. When the piston 13 is at its uppermost position, respiration openings 33 in the reservoir wall expose the inside of the reservoir to atmosphere to compensate for variations in atmospheric pressure. The writing mechanism shown in Fig. 6 comprises a collapsible reservoir 35. To fill the reservoir 36, a push button 38 having a conical extension 39 which co-operates with a flexible tubular sleeve 42 to form a valve, is unscrewed to the position shown in Fig. 7. When the reservoir is compressed, air is allowed to escape through the valve and respiration openings 48, but prevented from entering the reservoir when the same is released. Ink will then enter the ink openings 27 in the nib section 25, previously exposed by unscrewing the nib section 25. In a modification, Fig. 9 (not shown), a floating valve replaces the valve described above. In a further modification, the invention is applied to a ball-point pen, Fig. 11 (not shown) in which the respiration openings in the uppermost part of reservoir have a weak rubber sleeve over them to operate as a valve when filling the pen. This sleeve, however, does not prevent the respiration openings from compensating when there is a change in atmospheric pressure.

Title: Improvements in or relating to methods of reducing the neutral oils content of phenols mixtures
Inventor: MCCULLINS JOHN THOMAS
IPC: C07C37/86
Filed: 1955-05-23
Abstract: Mixtures of phenols which contain neutral oils are purified by treating the impure mixture with a lower aliphatic alcohol, this being effected by heating and maintaining the mixture at a temperature between the boiling-point of the alcohol and the boiling-point of the mixture, and passing the vapours of the boiling alcohol therethrough.  The purified phenol product is suitable for plastics manufacture.  In an example, a phenols mixture containing more than 0.5% of neutral oils is run into a still, and its temperature is maintained at 120-130 DEG  C.  The vapours of boiling ethanol are passed into the hot mixture; and the distillate, which contains the neutral oils, is collected. Some of the alcohol is retained in the phenol mixture; and this is recovered as an azeotrope with the various phenols present, the distillation being stopped at 178 DEG  C.  The azeotrope distillate is diluted with water (or saline), and the small amount of phenols therein is thereby recovered; this fraction, however, is contaminated with neutral oils. The distillation-residue forms the purified phenols product.
