Title: Process for improving the electrical resistance of animal fibres
IPC: D06M11/05
Filed: 1937-07-20
Abstract: The electrical resistance of natural silk and wool yarns is improved by treating with dry steam.  The material is preferably first treated to remove natural salts, e.g. with acid, such as acetic or hydrochloric acid.  Conditions before and after the treatment with dry steam are such that condensation of steam is prevented, e.g. by heating the material to above 100 DEG  C. before treatment, and drying after the treatment.  In an example, a chamber is heated to 150 DEG  F., silk skeins placed therein and the temperature raised to 220 DEG  F., steam at 220 DEG  F. is passed through for about 20 mins., and remaining steam extracted by an exhaust fan, the silk is dried out in the chamber, allowed to cool and then removed.

Title: Improvements in internal grinding machines
IPC: B24B49/18
Filed: 1933-07-19
Abstract: 424,261. Internal-grinding machines. CHURCHILL MACHINE TOOL CO., Ltd., Broadheath, near Manchester, and ASBRIDGE, H. H., Reigate, Moss Lane, Ashton-on-Mersey. July 19, 1933, No. 20361. [Class 60] The worktable of an internalgrinding machine when moving to grinding position connects the driving means to a mechanism for a mechanically timed cycle of operations which proceeds to its completion independently of further movements of the table, the mechanism comprising means to control the feeding of the grinding wheel to and from the work, and a tappet wheel which makes one revolution during the cycle and controls feed compensation for wheel wear, the reversal of the worktable, and disconnection of the drive to the mechanism at the end of the cycle. In the grinder shown, the worktable a is moved to grinding position by hand operation of the reversing handle s controlling the flow of fluid to the hydraulic operating cylinder, and is then reciprocated during grinding by a mechanically-oscillated stop c which engages an abutment d on the table, as described in Specification 415,879. When grinding position is reached, a dog p on the table engages a lever t and causes it to raise a drop-worm w, carried by pivoted arms v, Fig. 2, and driven by a belt w<1>, into engagement with a worm-wheel 2. The worm is retained in this position by a rod x pivoted to the lever t and having a recess in which engages a locking slide when it is in the raised position. On the shaft 3 of the worm is a face-cam 4, Fig. 2, against which a pin 7 on the cross-slide 5 of the wheel head is caused to bear by a weight 8, and which causes the in and out feed movements of the slide. Also mounted on the shaft 3 is the wheel 9, carrying tappets 10, 14, 22. During rotation of this wheel the tappet 14 engages a sliding rod 15, Fig. 1, which operates through a pawl 16 and ratchet wheel 17 a worm 18, Fig. 2, and through it a worm wheel 19 which rotates a sleeve 20 revoluble on the shaft 3 and having a screwed end engaging a nut 21 against which the cam 4 bears. The nut and cam are thus moved axially to compensate for wheel wear. On completion of grinding, the tappet 10 engages a plunger 11, which through a lever 12 and link 13 reverses the handle s and causes the table a to be moved away, a dog q on the table bringing the handle to neutral position at the end of the stroke. Finally, the tappet 22 on the wheel 9 causes the locking-slide to release the rod x, which drops and allows the worm w to disengage from the wheel 2. During movement of the table to grinding position, a tappet 25, Fig. 5, on it causes fluid to be supplied to a cylinder k which causes rotation about an axis j of a wheel trueing tool and brings it into the operative position shown in full lines.

Title: Improvements in or relating to wort production
Inventor: CLYTON DAVID HENRY
IPC: C12C7/047
Filed: 1968-05-15
Abstract: 1,202,976. Producing wort. A. B. M. INDUSTRIAL PRODUCTS Ltd., and K.K.K. KROYER. July 8, 1969 [May 15, 1968; April 22, 1969], Nos.23028/68 and 20409/69. Heading C6E. A method of producing wort from an aqueous slurry of starch- and protein-containing plant material involves the steps of liquefying starch by treating the slurry with a commercial starch liquefying enzyme (bacterial alpha-amylase), sub; jecting the slurry to hydrodynamic conditions such that a substantial thixotropic reduction of viscosity is produced by shearing forces in the slurry to facilitate the action of the starch liquefying enzyme prior to any substantial reduction of viscosity resulting from the enzymatic liquefaction, converting starch to sugar by treatment with a saccharifying enzyme (e.g.#-amylase added in the form of malt, amyloglucosidase or fungal amylase) and converting protein to soluble nitrogen-containing compounds by treatment with a proteolytic enzyme (bacterial or fungal protease). The hydrodynamic conditions are produced by forcing the slurry with a pulsating movement through a steam heated annular passage 9mm. wide at a velocity of 0À75-6 metres per minute and under a pressure between 15 and 35 atmospheres. Thereafter the medium is conducted through a conduit of such length that the liquefaction proceeds, at a temperature of 86‹C., to a point where the medium is no longer gelatinizable by cooling. The medium is then treated simultaneously with the saccharifying enzyme and proteolytic enzyme at a temperature between 25‹ and 60‹ C. and pH between 4À5 and 6À5. The medium finally may be heated to 70‹ or 80‹ C. to convert any non-gelatinized starch into soluble carbohydrate. After filtering, the product is concentrated to a syrup. Plant materials: Unmalted barley, wheat or maize, rice, tapioca, roots, fungal material and byproducts of processes to which cereals have been subjected. Where the nitrogen content of the material is low, amounts of soluble protein may be added to the wort to render it suitable for the production of beer. The hardness of the water of the slurry should lie between 200 and 300 equivalent parts by weight of calcium carbonate per million parts by weight of water.

Filed: 1944-10-21
Abstract: 597,882. A.C. generators. ARNOT, A. R. E. Oct. 21, 1944, Nos. 20438/44 and 11547/45. [Classes 35 and 38 (iv)] A governed frequency polyphase alternator has its rotor excited from polyphase rotating brushes on the exciter commutator, the brushes rotating at a speed proportional to any speed variation between the alternator rotor and a governing motor. In one form, the rotor 12 of alternator 11 is fed through slip-rings 14, 15, 16 and 32, 33, 34 from rotary brushes 27, 28, 29 on the commutator of the exciter 20 which derives its own excitation from brushes 25, 26. A differential gear drives the brush carrier 30 at the speed difference between the alternator shaft 13 and the constant speed governing motor 46. In a modification, Fig. 2 (not shown), the differential gear is replaced by a synchronous motor, one member of which is driven by the alternator shaft and whose other member which drives the rotary brush-gear is energized by a constant frequency supply. In a further form, Fig. 5 (also not shown), the exciter is replaced by a commutator connected to the alternator stator winding, the brushgear being driven and supplying the rotor as before. The governing motor now runs at twice the output frequency. In some cases, to avoid sparking, a pressure casing may be used or two commutators may be employed having alternate tappings from the armature and the brushes connected through currentlimiting devices. When driven by an A.C. motor, the whole machine acts as a frequency changer.
