Title: Improvements in or relating to processes and devices for the production of dough forbread and like baked pastry products
IPC: B01F15/00
Filed: 1953-09-30
Abstract: 777,251. Making bread and like dough. STRAHMANN, H. Sept. 30, 1953 [Sept. 30, 1952; May 30, 1953; Sept. 5, 1953], No. 26890/53. Class 86 [Also in Group VI] A process for continuously preparing dough for bread and the like consists in kneading flour and water together with convential additives such as doughloosening agents, baker's yeast and the like in a continuous kneading device, the water being evenly distributed among and caused to penetrate into the particles of flour to form a dough which leaves the kneading device after a total treatment time therein of less than one minute so that no gluten network is formed and the yeast has not become effective by the time the kneading is completed, the amount of water added to the other raw materials being greater than the amount that would be used in a normal batch process employing the same type of flour to produce a dough of the same consistency after the appropriate rest period. The solid raw materials and water in excess of the usual amount by about 5 litres per 100 kg. of flour, are continuously fed into a preliminary kneader 10 and treated therein by sets of kneading vanes I, II, arranged on a rotating shaft 2 and are then passed through a further kneader 11 which consists of a number of recessed perforated plates 13 clamped together by bolts 14, mounted for rotation in the opposite direction to the shaft 2, the shaft 2 being provided with sets of kneading vanes 26 between the plates 13. The dough emerging from the kneader 11 passes through a discharge pipe 21 which has a severing blade 35 arranged to cut the dough into lengths. The cut pieces of dough are fed by an endless belt 39 to an endless band moulder 40, 42, and a period of about 2 minutes elapses between leaving the mouthpiece of the pipe 21 and passing between the two bands 40, 42. The perforations in the plates 13 may be formed as shown in Figs. 10, 12 and 13. The raw materials may be charged into the preliminary kneader 10 through a single cylindrical inlet 7 which is provided with a scraping blade 9 moving around its inner surface with a vertical reciprocation so that its lower end follows the line of intersection of the inlet 7 and kneader 10. Alternatively separate inlets 53; 54, Fig. 8, may be provided for the liquid ingredients, with a separate inlet 52 for the solid ingredients disposed upstream of the inlets 53, 54, so that the formation of crusts on the mouth of the solid material inlet is avoided. The preliminary kneader 10 has a heating or cooling jacket 30.

Abstract: 428,757. Sharpening razors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 19, 1934, No. 26932. Convention date, Sept. 19, 1933. [Class 60] A razor-blade sharpening- machine driven by an electric motor comprises a plate 10 having pivoted, in upstanding portions 19 thereof, casings 16, 37 respectively carrying pairs of rollers 11, 12 and 13, 14 geared together, the lower rollers 11, 13 being driven by a worm 48 on the spindle 43 of the armature 42 of an electric motor 41 mounted beneath the plate 10. Each roller has therein a spiral groove 31 in which is a stropping member 23 having its ends entering holes in the roller body and locked in position by bushings 35, 36 inserted in the bore of the roller, and the spindles 17 of the upper rollers are journalled in oval openings in the casings 16, 37 and the pairs of rollers are pressed together by springs 26. The casings 16, 37 are normally separated by a spring 40, and are moved to engage a blade mounted on tapered pins 53, 54 by cams 51, 52 on a lid 50 hinged to a housing 49 containing the motor &c., and the inward pivotal movement of the casing 16 causes, through a cam surface 16<1> on the casing and a pin 58, movement of a contact 56 to engage a contact 55 to start the motor. In order to time the operation of the sharpener, contacts 59, 60 are provided, the contact 59 being moved up to contact 60 when the casing 37 moves to the inoperative position, and latched in the closed position by a bimetallic strip 63 surrounded by a heating-coil 64 in the circuit of the motor. When the motor has run for a sufficient time, the strip 63 moves and allows the contacts 59, 60 to separate ; the contacts will not be latched again until the strip has moved back to its normal position, thus preventing overheating of the motor.

An actuator 60, Figs.7 and 9, has a doubleacting piston 118 for adjusting the pitch of the first stage stator vanes of the high-pressure compressor of a gas turbine by-pass engine,and has a collar 63 for sealing engagement with an aperture 61 in the engine casing 34. Moreover, at each end of cylinder means 110 there is a respective externally-threaded adjustable stop 148 for adjusting the piston stroke. Each stop 148 has passages 150 therein in communication with a pipe 146 for selective delivery and return of high-pressure engine fuel to and from the cylinder means for adjusting the position of the piston 118, and thereby the pitch of the stator vanes via arm 82, shaft 74, arm 72, rod 58 and a ring 54. Rotation of the piston is prevented by a pin 128 which slides in a slot 130. High-pressure air chamber 70 Fig.7 is sealed by chevron packings 88 from a chamber 90 Fig. 9 which is communicated with the relatively low-pressure of the fuel-pump intake so that leakage through the packings is in the safe direction. Access to the packings is facilitated by removable end covers (96, 98), Fig.8 (not shown). Access to chamber 70 for adjustment of chevis bolt 64 is facilitated by a removable cover 76, Fig.3 (not shown).

Abstract: 1,182,026. Valves. ALLIS-CHALMERS MFG. CO. 11 June, 1968 [20 June, 1967], No. 27653/68. Heading F2V. In a butterfly valve having an uninterrupted 360-degree conical seating 7, movement of the closure member 8 from the closed position shown to the fully open position is effected by two separate actuators, the first of which moves the closure member away from its seat and the second of which subsequently rotates the closure member. To this end, each of the closure member trunnions 9 and 11 extends through an elongated opening 12 in the valve housing 6 and is journalled in a slidable bearing 13 to which the piston-rod 19 of an actuator 18 is rigidly connected. A further actuator 21, which is pivoted to the valve housing and contained within a stream lined casing 24, has its pistonrod 23 pivotally connected to the valve member at a point spaced from its rotational axis. In operation, energization of the two actuators 18 causes sliding movement of the bearings 13 and hence displacement of the valve member 8 from its seat 7, whereupon energization of the actuator 21 causes rotational movement of the valve member, the clearance created between the seat and member by actuators 18 being such that during its rotational movement the closure member does not engage the seat.

Abstract: 502,335. Lubricating -compositions. STANDARD OIL DEVELOPMENT CO. Sept. 23, 1938, No. 27736. Convention date, Dec. 23, 1937. [Class 91] A lubricating composition for Diesel engines comprises a non-waxy lubricating fraction containing from 0À1 to 3 per cent of a metallic soap of acids derived from the oxidation of " sweater oil." The soap may be an Al, Ca, Di, Sn or Mg soap, and is oil-soluble or rendered oil-soluble by an organic solubilizer. " Sweater oil " is the oil obtained by subjecting crude scale wax to a second sweating operation. In an example, 1À7 per cent of Al soap of oxidized " sweater oil" is added to a non- waxy naphthenic oil obtained from a Coastal crude and having a Saybolt viscosity of 55 secs. at 210F. The mixture is heated to about 175 to 200 F., till complete solution is effected. After standing in storage for three and a half months, the oil shows no haze, gelling or other evidence of separation of the soap. Other agents, such as oiliness increasers, corrosion inhibitors, antioxidants, extreme pressure agents, thickeners or dyes may be added.
