Title: An improved method and apparatus for preparing brewers wort
Inventor: WATTS PERCY HENRY
IPC: C12C7/14
Filed: 1961-04-14
Abstract: <PICT:0943811/C3/1> In a continuous mashing process, filtration of the wort is effected by spreading the mash after conversion on a perforate conveyer so that a settled filter bed of grains is formed through which the wort percolates.  Mash issuing from a mashing vessel 19 is spread by a spreader 26 over a level or slightly inclined perforate conveyer belt 20, e.g. of 20-mesh nylon, driven by a roller 23 and guided by rollers 20 over a perforated support comprising slotted plates 21, which is imperforate however at the point of deposition of the mash.  Wort passing through the filter bed of grains 36 (Fig. 4, not shown) is collected in tanks 25 arranged in batches. The first batch of tanks underlies the stabilizing region of the belt 20 in which the filter bed is formed and cloudy wort passing through into any tank is recirculated by a pump 27 to pass through the belt filter bed into the succeeding tank.  The wort is then collected in a central production region in a main collecting tank 28. Farther downstream the filter bed grains are sparged with hot water and the weak wort received below the belt 20 is sparged over the production region and/or directed to tank 28. Weirs of progressively decreasing height between the filter bed and tanks 25, or alternatively a sloping belt 20 produce a gradual lowering of the level of liquid in the mash on the conveyer.  A scraper 29 removes spent grains from the belt which are ejected through an outlet 30 in a clean plastic cover 32 enclosing the apparatus. The belt is back-washed clean with water on its return run below and a heating jacket 31 surrounds tanks 25 and belt 20.  The conversion of the mash may take place on the belt 20 over an imperforate upstream heated extension to the support 21.  Alternatively one or more separate heated belts may be used.  A conversion method and apparatus are described in Specification 943,812.  Specification 852,561 also is referred to.

Abstract: 798,045. Moulding resin-fibre tubes &c. COMPAGNIE DE PONT-A-MOUSSON. May 2, 1956 [May 9, 1955; March 21, 1956], No. 13511/56. Class 87(2). [Also in Group VIII] A thermosetting resin tube having one or more tubular reinforcements of interwoven glass fibres is moulded by braiding therein forcement on an inflatable mandrel, introducing the mandrel into a centrifugal mould 12 mounted on driven rollers 13 in an oven, having heaters 16, inflating the mandrel to force the reinforcement against the mould, and removing the mandrel. The mould is then rotated to again force the reinforcement against the mould, the resin is introduced through a spout 22 into the mould, whilst its speed is reduced or stopped. An end ring 20 limits the thickness of the tube. The mould is rotated at high speed to form the tube. The fibres of the reinforcement are free to move at the points where they intersect which allows the reinforcement to be deformed without tending to return to its former shape. In a modification, Figs. 7 and 8 (not shown), the reinforcement may be made on a rigid mandrel the ends of the reinforcement being moved together to expand the reinforcement and to allow it to be removed from the mandrel. The mould may have a flared end to allow the reinforcement to be introduced easily and if desired this flared end may form a socket on the end of the tube. The reinforcement may be coated with a binder (soluble in the resin) to stiffen it, prior to its introduction into the mould.

Abstract: 217,226. Siemens - Schuckertwerke Ges. June 5, 1923, [Convention date]. Dynamos, regulating; motors, controlling.-A compound-wound dynamo suitable for use on motor vehicles has the series coil reversible, whereby it may function as a differentially-compounded cell-charging generator, as an additivelycompounded engine-starting motor on the battery, or as an additively-compounded generator for lighting or other purposes, the shunt and series coils being so designed as to give constant charging output. In the form shown, the commutating, series and shunt windings 13, 15, 14 are connected to two sets of contacts H, E and V, C of a controller to which are also connected at B, L, K the open terminals of the battery, lighting and other power-consuming circuits 11, 6, 6<1> which have a common connection at 1 with one pole of the machine 12. When the controller lines I, III register with the contacts K, F, H, E, S, the lines II, IV register with the other row. With the line I at K, S, the machine acts as a differentially-compounded generator charging the cells, or, if the engine be at standstill as an additivelycompounded starting motor. With the line II at K, S, the current in the series coil is reversed giving an additively-compounded supply to the circuit 6<1>, the lamps 6 being on the battery independently of the generator 12. With the line IV at K, S the lighting load is on the cells, leaving the dynamo unexcited and running light on the engine, and with the line III at K, S the circuits are all open. A flashing resistance 9 is permanently connected across the shunt coils and a part of the shunt resistance 7 is cut out during the charging. The shunt resistances are adjusted to give maximum efficiency on counter and additive compound working.

Abstract: 873,392. Magnetic switches. ROBERTSHAW FULTON CONTROLS CO. April 23, 1959 [July 1, 1958], No. 13913/59. Class 38 (5). A switch has two contact-carrying magnetizable members which attract each to engage their contacts on the approach of a magnetizing member. The magnetizable members 10, 12 are formed of a disc bent along a diameter to form armature legs 18, 20 and contact legs 14, 16 secured to flat springs 24, 26 held in the cap 28 of a sealed vessel 32 which may be filled with an inert gas. Contact protrusions 22 are formed on the legs 14, 16 and are spaced from the centre of mass of the members 10, 12 so that the contacts roll over each other on engagement. The magnetizing permanent magnet 46 is carried on a bi-metallic spring strip 44 which under changing temperature conditions moves the magnet towards the members 10, 12 until the spring bias of the strip 44 is overcome by the magnetic attraction and the magnet snaps to a position where an adjustable screw 48 engages the bottom 42 of the vessel 32. This increases the attraction between the members 10, 12 which overcome the bias of the springs 24, 26 to engage contacts 22. The force of springs 24, 26 is less than that of the bi-metal spring 44 so that the contact closing force exceeds the force necessary to restore the magnet 46 to effect contact separation. The members 10, 12 may be coated with silver, the coating over the contacts 22 setting a residual gap. In Fig. 6 a spiral bi-metal spring 50 expands to rotate the magnet from the position shown until the poles are in line with the armature legs 18, 20 and are attracted thereto to close the contacts.
