Title: Improvements in and relating to moulding machine for viennese, french and fancy bread
IPC: A21C7/01
Filed: 1947-11-27
Abstract: 652,385. Sheeting and rolling-up dough. RECORD BAKERY EQUIPMENT CO., Ltd., and FOX, F. F., (formerly FUCHS, F. F.). Nov. 27, 1947, No. 31437. [Class 87 (ii)] A dough-moulding machine for sheeting and rolling-up dough pieces comprises, two pairs of contra-rotating rollers 2, 3 ; 8, 9, respectively, Fig. 1, the upper roller of each pair being eccentrically mounted to permit simultaneous adjustment of the bight between each pair, and two endless belts 21, 30 travelling in opposite directions where they face one another. The roller or drum 9 is journalled in the main frame 1, the end 9a of its axle carrying a gearwheel 12, Fig. 3 (not shown), rotated by a gear-wheel 13 on the driving shaft 14, while the axle 9b, Fig. 4, carries a triple sprocket wheel 15 which chain drives the roller 2, Fig. 1a, the drum 22 of the lower belt 21, and the upper belt drum 31. The rollers 3, 8 which rotate at different speeds are eccentrically mounted at each end by means of crank members 4, 10, having spur gears 4a, 10a, respectively, which gears are adapted to be rotated to adjust the eccentricity of the rollers by means of a worm 7, wheel 6, and toothed sectors 5, 6b, on the shaft 6a. The lower belt tension may be adjusted by a device 43, and may be tilted by a hand-lever 27a, Fig. 2 (not shown), attached to an arm 26 pivoted at 27 in the frame 1 which arm carries the lower drum 22. The upper belt may be tensioned by an arrangement of rollers 35a, 35b, Fig. 1, eccentrically mounted on a disc 35 having a gear-wheel 35c rotated by a worm 35d. A frame 34, pivoted co-axially with the axis of the drum 31, has an angular counterpoised lever 36, and bearings 33a, 33b for the roller 33 around which the upper belt 30 passes. The lower part 36d of the lever 36 has an elongated slot 36e, the upper end of which rests on an eccentric cross-member 37 pivoted in the main. frame 1 at 37a, Fig. 5 (not shown). This eccentric can be turned by a handle 37b and fixed in position by a clamp 37c. By turning the eccentric the frame 34 and upper belt 30 may be raised or lowered to adjust the distance between the belts 31 and 30. Adjustment of the counterpoise 36b secures a slight anticlockwise overbalance of the frame and its rollers with a resulting slight pressure of the belt 30 on the dough. The dough may be dusted with flour through a slot 41a from a flour compartment 41 by means of a rotary brush 40 driven by a chain 38 from a sprocket wheel 31b. Scrapers 42 are pivoted in the main frame 1 and biassed against the rollers by springs 42a. In operation, dough pieces are fed between the rollers 2, 3; and then between the rollers 8, 9, which have a smaller bight. From. this second pair of rollers the dough is fed on to the lower belt 21 contacting the roller 9, which belt in co-operation with the upper belt 30 rolls the dough pieces and delivers them to the plate 25.

Title: Improvements in height indicating apparatus for aircraft
IPC: G01C5/06
Filed: 1935-11-14
Abstract: 465,787. Remote control systems. ROBINSON, J. Nov. 14, 1935, No. 31575. [Class 40 (i)] The zero relationship between a pointer and a dial is adjusted in accordance with a characteristic of a received wireless signal. The invention is described as applied to an altimeter in an aircraft, the zero being corrected as barometric pressure on the ground varies. The received signal is passed by frequencychanger 10 and signal acceptor 12 to resonant devices 13, 14 which are tuned respectively to the limits of the range of frequencies passed by acceptor 12 and have oppositely sloping characteristics. At the mean frequency the outputs of 13, 14 are equal. If barometric pressure varies the wave-length of the transmission is changed and the outputs of 13, 14, which are rectified by 15, 16, do not balance and drive motor 17 which alters the tuning of the local oscillator 11 until the signals applied to 13, 14 are equal, as regards frequency, to the mean frequency. The motor 17 also drives shaft 23 which corrects the reading of the altimeter either by rotating the dial, as shown in Fig. 1, or by moving the pointer as indicated in Fig. 2.

Title: Adaptive closed loop control system
IPC: G05B13/02
Filed: 1965-07-26
Abstract: 1,109,885. Automatic control. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 26, 1965 [Aug.14, 1964], No. 31709/65. Heading G3R. In a closed-loop control system in which the magnitude of components of the control signal are measured at at least two frequencies at which the effect of a disturbance signal is and is not respectively dependent on loop gain, the measurements are modified and compared so that they are unequal and serve to adjust loop gain when the latter deviates from a desired value. As described, e. g. for automatically controlling the flow to a reservoir in dependence on fluid level therein, for automatically controlling the steam supply to a catalytic cracker in dependence on the percentage of a constituent of its output, or for controlling elevons of an aircraft in dependence on signals from a rate gyro, the measured value is compared with a desired value and the error signal so derived is applied through a variable gain device and added to differential and/ or integral components for control purposes. The error signal is also applied to a number of bandpass filters followed by absolute value determining devices, limiters and amplifiers to obtain signals representing the magnitudes of components of the error signal over different frequency bands. One of these bands is chosen so as to be one in which the relative magnitude of the component is very dependent on the gain of the control system and the other bands correspond to disturbances such as noise, mechanical vibration, &c. in regions substantially independent of gain. The gain-dependent component signal is subtracted from the sum of the other component signals and the difference compared with a reference signal to obtain a gain error signal which is applied through a non-linear device to control the gain of the variable gain device and hence maintain response of the control system at an optimum automatically. Methods of filtering employing two overlapping pass bands, and manipulating and comparing the signals by programming a digital computer which periodically samples the error signal are described.

Title: Removal of surface-active contaminants from hydrocarbon oils
IPC: B03D1/14
Filed: 1958-10-07
Abstract: <PICT:0830128/III/1> A process for the removal of surface-active constituents from a hydrocarbon oil comprises foaming a portion of the oil with a gas and separately recovering oil containing surfaceactive compounds and an oil containing a reduced amount of surface-active constituents.  Gases which may be used include carbon dioxide, nitrogen, methane, ethane, propane, propylene, butane, refinery gases, air, ammonia, oxygen and steam.  Condensible gases are particularly suitable since they permit the separated foam to be collapsed by cooling.  Foaming may be assisted by reducing the viscosity of the oil with a diluent, e.g. 200-400 DEG  F. aliphatic fractions, kerosines and heavy naphthas, or by adding water. Whilst most surface-active contaminants occur in fractions boiling above 950 DEG  F. the process is preferably applied to broad cut fractions with an I.B.P. well below 950 DEG  F.  A hydrocarbon oil having a F.B.P. above 950 DEG  F. is introduced into foaming vessel 1 through line 2. A solvent, e.g. between 1 and 4 parts of kerosine, may be added to reduce the viscosity of the oil, either in admixture with the oil in line 2 or separately through line 4. Air or other gas is introduced through line 6 to distributer 7 and the oil level 8 is maintained at a point between the points of introduction of the feed and the gas by removal of product oil through line 9 from a point below distributer 7.  Foam is taken from the top of the column by line 10 to defoaming zone 11 where it is separated into gas which is removed via line 12 and oil enriched in surface-active agents which is either removed via line 14 or recycled to the top of the column via line 15.  Reflux ratios of 1 : 1 to 1 : 10 may be employed.
