Title: Apparatus for, and method of, making bread
IPC: A21D8/02
Filed: 1955-11-18
Abstract: Bread dough is produced by forming a brew by anaerobic fermentation at controlled temperature, e.g. at 70-90 DEG  F. for 5 hours, of a mixture of water, non-fat solids of milk, sugar, salt, yeast and yeast food, incorporating this brew in formula quantities of flour, shortening and oxidant, e.g a potassium bromate and potassium iodate solution, and subjecting the mixture so formed to mechanical dough developing action at pressure above atmospheric, e.g. 40-90 lb./sq. inch.  Part of the sugar, of the water, or of the salt may be added after the fermentation.  The brew may be cooled, e.g. to 40-80 DEG F., before it is incorporated in the flour, shortening and oxidant. Specifications 788,827 and 808,836, [both in Group II], are referred to.

Title: Improvements in or relating to door-closing devices
IPC: E05F3/06
Filed: 1956-10-30
Abstract: 832,993. Door operating appliances. MANKEL, R., [trading as DORKEN & MANKEL KOMM.-GES.]. Oct. 30, 1956 [Aug. 3, 1956]. Class 65(1) A hydraulically checked floor spring comprises a spiral closer spring having a spring tensioning device which is connected by at least one articulated linkage to a door closer spindle, the maximum closing torque being exerted on the spindle when the door is in its closed position. One end of the spiral spring 14 is fixed to the housing 1, the other being secured to a tensioning device 9 journalled in the housing and having a rocking lever 10 rotatably engaged with its lower journal. Links 12 pivotally connect the cranks 13, rotatably mounted on the door closer spindle 4, with the rocking lever. Opening of the door in either direction rotates the closer spindle and a drive member 15 on the spindle operates one or other of the cranks to rotate the rocking lever and wind up the spring. A second drive member 27 on the spindle engages a slotted guide 'member 18 to rotate a crank 20 and operate the piston of the hydraulic check means, the guide member, and the piston, being returned as the door closes by a closer spindle cam 17 co-operating with a roller 19 journalled on the guide member. The cylinder of the check means has a restrictor valve by which the damping effect may be varied, and a by-pass port uncovered by the piston skirt as the door approaches the closed position to then release the checking effect. The spring is initially tensioned with the door in the closed position by rotating the member 10 through the required angle and inserting a screwed pin (not shown) through one of the bores in the member 9 into a single screwed hole in the rocking lever 10. In a modification using cranks integral with the closer spindle, two chain-like linkages connect the crank to a single pivot on the rocking lever. In a further modification for a unilaterally opening door having 180 degrees of swing a single crank integral with the closer spindle is employed with a single articulated linkage connecting it with the rocking lever.

Title: Combustion engine fuel injection apparatus having fluidic control means
IPC: F15C1/00
Filed: 1970-07-08
Abstract: 1315974 Fluid logic and switching circuits; spray carburetters BENDIX CORP 8 July 1970 [9 July 1969] 33212/70 Headings FIB and F1P Each of a plurality of cylinders of a conventional I. C. engine has its individual air inlet pipe 22 and exhaust pipe 32 connected to an individual fluidic apparatus 34 for controlling the supply of fuel to a nozzle 38 in air inlet 22 independently of the remaining cylinders and comprising a fuel powered proportional amplifier 136 having an outlet 142 connected to nozzle 38 for supplying fuel thereto in response to air pressure signals supplied to a control port 144 and generated by an amplifier set 88, 104, 120 and which vary with the temperature of the exhaust and inlet. An opposing control port 152 of amplifier 136 is supplied with a reference desired exhaust gas temperature air signal through a line 74 and a branch line 82 of a passage 182 subjected to atmospheric pressure and vacuum at opposite ends, and containing fixed restrictions 184,186 and a by-pass valve 192 mechanically linked to a throttle valve (28) Fig.1 (not shown) in the main air inlet manifold (26). The desired exhaust gas temperature giving rise to the control air pressure at 152 is obtained when valve 192 is closed in response to throttle valve (28) being in engine idle or maximum power position and when desired temperature equals the actual exhaust gas temperature the air pressures at 144, 152 are equal and the fuel input at 138 is divided equally between output 142 to nozzle 38 and to output 140 leading to a return reservoir. In the event of an excess actual exhaust temperature the air-pressure signal at 144 increases resulting in more fuel being directed to nozzle 38, and with a constant cylinder air flow a richer mixture and a corresponding reduction in cylinder exhaust gas temperature. Line 74 and hence control port 152 is also connected to the output 158 of a further manifold air-pressure sensitive fluidic device 66 whereby a sudden opening of throttle valve (28) giving rise to a sudden increase in manifold pressure biases the output of 66 away from 158 and so.reduces the pressure in 74 which results in increased fuel flow to nozzle 38. The air pressure pulses supplied to control port 144 of amplifier 136 and which are responsive to the actual exhaust gas temperature are derived from the output 126, 146 of a mono-stable amplifier 120 having opposed control inlets 128,130 connected respectively through a line 134 at ambient air temperature and a line 132 having a portion thereof subjected to exhaust gas temperature to outputs 110,108 of a bistable amplifier 104 slaved to an oscillator amplifier 88. The latter is exposed to ambient air and the outputs 92, 94 have feedback passages to control input ports 100,102 thus producing alternate pressurization in lines 116,118 leading to control inputs 112,114 of amplifier 104 which in turn produces alternate pressurization of output passages 108,110.

Title: A method of obtaining from flax or other plants an improved fibre suitable for spinning by machinery of the kind used in cotton mills
IPC: D01C1/02
Filed: 1927-12-08
Abstract: 309,213. Vickers, Ltd., and Lucas, O. D. Dec. 8, 1927. Retting.-Retted and unretted and scutched or unscutched flax or the like having nodes are subjected to chemical treatment whereby the nodes are destroyed or weakened and all the ultimate fibres remain unbroken after passing through a carding or other suitable process to separate the ultimate fibres from each other. The treatment produces a fibre suitable for spinning by,machinery of the kind used in cotton mills. The scutched flax preferably unretted is first treated with 3-5 per cent caustic soda solution at 150-170 C. for 1-4 hours, to which solution a plasticizer consisting of 1¢ per cent Turkey red oil and ¢ per cent linseed oil may be added. The material is then washed, preferably in soft water, and immersed in a cold bath containing ¢-2 per cent hydrochloric acid, again washed and then dried for spinning. In treating unscutched flax the material is first digested in water at 182 C., the furfural produced is distilled off and the product is treated as above. The fibres can then be separated by either wet or dry processes. Jute, hemp, ramie and the like may be similarly treated, and any other chemical process for destroying or weakening the nodes may be used.

Title: Improvements in or relating to the jointing of hollow, oil-filled electric cables
IPC: H02G15/20
Filed: 1931-12-01
Abstract: 386,093. Cable joints. SUDDEUTSCHE KABELWERKE ZWEIGNIEDERLASSUNG DER VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES., 244, Waldhofstrasse, Mannheim, Germany. Dec. 1, 1931, No. 33261. Convention date, Dec. 4, 1930. [Class 38 (i).] In jointing oil-filled cables the end of the hollow conductor a forming the oil channel is closed by a hollow plug b having one or both ends closed by discs c of a fusible metal. After making and insulating the joint in the ordinary way the oil passage through the joint is opened by melting the end c of the plug by warming the joint. The fusible metal is chosen to melt at about 100‹ C. When the cable is opened and plugged, the plug is inserted far enough to prevent leakage of oil through the bare cable end, and the end is chilled to prevent percolation of the oil through the cut insulation. Air may be exhausted from the joint after completion. The Specification as open to inspection under Sect. 91 comprises also the use of a filling for the hollow plug, consisting of a fusible material soluble in the oil, e.g. a mixture of oil and resin. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the production of regenerated cellulose fibres from viscose
Inventor: SMITH JOHN OLIVER
IPC: D01F2/06
Filed: 1953-12-03
Abstract: Regenerated cellulose fibres are produced by extruding viscose of salt figure below 3.5 into an aqueous coagulating bath containing below 5 per cent by weight of sulphuric acid and more than 20 per cent by weight of salts, including at least 5 per cent of magnesium sulphate, withdrawing the fibres from the bath at a rate equal to or lower than the extrusion rate of the viscose into the bath and subsequently completing the fixation of the fibres in an aqueous acid bath having a higher rate of concentration of acid to salt than the coagulating bath, but preferably less than the bisulphate ratio at which the concentration of ions is equivalent to a solution of sodium bisulphate.  The salt figure is defined as the concentration of a solution of common salt necessary just to coagulate a drop of viscose, and is preferably 0.5-3.5.  The preferred composition of the coagulating bath is 0.5-5 per cent of sulphuric acid, 10-25 per cent of sodium sulphate, 5-20 per cent of magnesium sulphate and a total salt content of about 30 per cent.  The extrusion rate of the viscose is preferably 1-20 times the speed of withdrawal of the fibres from the bath, to allow the fibres to thicken on emerging from the jet. The fibres are preferably passed through the regenerating bath in a relaxed condition or under low tension.  In an example, viscose containing 7.5 per cent of cellulose 7 per cent of caustic soda and 2.2 per cent of combined sulphur and aged to a salt figure of 1.2 is extruded into a coagulating bath at 55 DEG  C. containing 1.5 per cent by weight of sulphuric acid, 15 per cent of magnesium sulphate and 15 per cent of sodium sulphate.  The thread thus obtained is withdrawn from the bath at a rate of 40 metres per minute, the ratio of extrusion rate to take-up speed being 1 : 0.236, and is passed round a godet and through a second bath at 60 DEG  C. containing 3 per cent of sulphuric acid and a small quantity of salts carried over from the coagulating bath.  The thread then passes over a second godet and is collected in a centrifugal spinning-box.  The second godet travels at a lower speed than the first godet so that the thread is under low tension in the second bath.  The products give bulky yarns and fabrics and have a more irregular cross-section than have normal viscose fibres.
Patent GB-643902-A (GB)
Title: Improvements in radio receiving and frequency conversion systems
IPC: H04B1/26
Filed: 1947-12-19
Abstract: 643,902. Superheterodyne receivers. COLLINS RADIO CO. Dec. 19, 1947, No. 33628. Convention date, Jan. 30. [Class 40 (v)] In a double superheterodyne receiver the first frequency changer is fed by a tunable high-frequency local oscillator which is not stabilized, while a subsequent frequency changer is fed with a relatively low local frequency which is derived by mixing oscillations from the tunable oscillator with the output from a crystal controlled oscillator. This eliminates error due to frequency drift in the tunable oscillator. It also avoids spurious responses due to using the harmonics of relatively low frequency piezo crystals for the first oscillator, which would otherwise be necessary to obtain a large range of frequency. In Fig. 1, tunable R.F. input circuits 10, 11, 12 feed a first mixer 13 which also receives oscillations from a tunable oscillator 14. Elements 10 and 12 are tunable by knob 15 from 108-136 mc., while oscillator 14 is simultaneously tuned from 91.1-119.1 mc. This gives a first I.F. in the range 16.9-18.9 mc. which is fed through elements 16 ... 18 to a second mixer 19. The second local oscillations for feeding to mixer 19 are obtained from the tunable oscillator 14 which feeds a mixer 20 to which are also fed harmonics of a 2 mc. crystal oscillator 21, selected in a range 116-142 mc. by knob 15. The difference frequency 24.9 mc. after selection and amplification at 25 ... 27 is fed to a mixer 28 to which is fed the output from an oscillator 29 stabilized by twenty crystals in the range 9.3 mc. to 11.2 mc. and selected by a knob 31a. The output from mixer 28 comprises a range of 13.7-15.7 mc. in twenty steps, and is fed to the second signal mixer 19 to give a second I.F. of 3.2 mc. for each twenty values of the input frequency in each 2 mc. range selected by knob 15. The second I.F. after selection and amplification in stages 34...38 passes to detector 39 and subsequent stages. In the subtraction at the second signal mixer 19, the frequency of the tunable oscillator 14 is cancelled out. The second I.F. is thus independent of frequency drift in oscillator 14, and depends only on the frequencies of the crystal oscillators 21 and 29. In a modification (Fig. 3, not shown), the second local oscillation frequency is produced in three mixers. Then instead of using an oscillator with twenty piezo crystals, there are used an oscillator with ten crystals in combination with an oscillator having two crystals.

Abstract: 860,245. Gas-blast switches; hydraulic actuation of switches. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 23, 1958 [Oct. 30, 1957], No. 33936/58. Class 38 (5). In a gas-blast switch having a contact-rod 19 operated by the piston 20 of an hydraulic operating mechanism, a relatively low-pressure sealing-chamber 78 is arranged about the rod and provided with a drain 79 to prevent the entry of hydraulic liquid into the chamber 70 enclosing the switch contacts 18, 21. In the double-break arrangement shown, each rod 19 carries a combined piston and orifice member 17 which is moved into a cylinder 14 to establish the gas-blast. The pistons 20 carry racks 28 co-operating with a pinion 29 on a shaft 30 so that the movements of the contacts are synchronized with each other and the shaft 30 may operate an indicator (not shown). When the contacts are closed, the spaces 75, 76 on both sides of the pistons 20 are connected to an hydraulic accumulator 38, the differential action of the pistons maintaining the contacts closed. To open the contacts a pilot valve 64 is operated to admit pressure liquid to the space 67 below a plunger piston 46. This piston is moved up against the bias of a spring 49 and moves a slide-valve 47 up to close the communication between the reservoir 38 and space 75, and to connect the space 75 to a sump 55. The liquid pressure in the spaces 76 and acting on the smaller faces of the pistons 20 moves the pistons to open the contacts. Reclosure of the contacts is effected by operating the pilot valve 64 so that it connects the space 76 to the sump 55 and enables the spring 49 to restore the slide-valve. The hydraulic liquid may be oil and the gas within the chambers 70 and the supporting insulating column 9 and above the oil in the sump 55 may be sulphur hexafluoride under a pressure of 60 lb./sq. inch. Specifications 736,090 and 860,246 are referred to.
