Title: Process for extracting oleaginous materials that are rich in oil or otherwise unsuitable for treatment by ordinary methods of extraction
IPC: C11B1/10
Filed: 1933-11-17
Abstract: Fatty oils are extracted from raw materials containing a large amount of oil by submitting the material to a short preliminary extraction with a solvent to remove most of the oil and then extracting the remaining oil from the residue with a solvent by the usual methods. Crushed castor beans containing 44 to 48 per cent of oil are treated with a solvent which penetrates the material uniformly.  After a short period of 5 to 30 minutes the extract is drawn off, and if necessary a further extraction made, until about 60 per cent of the oil is removed.  The residue is then treated with a solvent in continuous circulation.  The extraction vessel is preferably provided with two independent sets of conduits for solvent and extract formed at each stage, and the separate extracts are distilled with steam to yield the respective oils.  The process may also be applied to the treatment of bleaching earths used in the purification of oils.

Abstract: 1,149,435. Inertial navigation. DORNIER SYSTEM G.m.b.H. July 13, 1967 [Nov.26, 1966], No. 32215 /67. Heading G1C. Flying bodies equipped with inertial navigation are guided shortly before landing to the desired landing spot by compensating and correcting the inertial navigation system for drift from a ground station which by taking bearings establishes the actual position of the body and by comparison with the position given by the inertial navigation system calculates a correction value which is used to effect correction of the position of the body. The invention is described as being used with a secondary radar system employing a transponder on the flying body to determine the actual position of the body, this being compared with the position given by the inertial navigation system in a computer. The computer generates a correction signal which is transmitted to the flying body to control a flight programming device thereon. In this way the landing of the flying body can be controlled to facilitate its recovery. A primary radar may be used in place of the secondary radar if desired but the latter is preferred.

Title: Improvements in change giving mechanism
IPC: G07F5/24
Filed: 1955-11-14
Abstract: 821,283. Change - giving apparatus. BRECKNELL, DOLMAN & ROGERS Ltd., and DOLMAN, H. J. Feb. 8, 1957 [Nov. 14, 1955; Sept. 11, 1956], Nos. 32535/55 and 27732/56. Class 27 A change-giving mechanism for a coinfreed vending machine comprises a rotor 8, Figs. 1 and 2, in the form of a rotatable cage subdivided by radial webs 9 into compartmental change-receiving pockets open at the periphery of the cage, the latter being rotated by a pawl 16 engaging with the webs and mounted on a pivoted lever 14 connected through linkage with an article-delivery drawer which, when opened, brings the rotor to a position for the delivery of change. The rotor 8 is rotatably mounted on a pin 6 secured to a wall 5 forming part of an enclosing casing 1; the pockets are arranged to accommodate various sizes of coins A, B, and are each subdivided by one or more partitions 11. The lever 14, pivotally mounted on the stud 6 and carrying the spring-urged pawl 16, is connected by a link 26 to one or more of the delivery drawers so that the opening of any drawer rocks the lever which causes the pawl to engage the web 9 of a pocket and index the rotor to the change-giving position. A second pawl 18 is provided With active ends 18A, 18B to prevent reversal and over spinning of the rotor and a spring 23 is provided for returning the lever 14 to its initial position. In the modification shown in Figs. 10 and 11, the rotor is formed from two side plates 52, 53 on a hub 55 and the pockets, which are not subdivided, are formed by removable steel vanes 51 located in the side plates. Each pocket accommodates coins of various sizes and to prevent wedging of the coins extra clearance may be provided by spacing the radial inner ends of the vanes from the hub 55, providing holes 58 in the vanes, or fitting a stepped block in the bottom of each pocket. The lever 14, Fig. 10, is provided with a spring-urged operating pawl 62, 65 and a second spring-urged pawl 67 prevents reversal and overspinning. Upon opening of a drawer, the operating bar 26 (which is actuated by a rod 73 through a spring 74) acts upon a pin 63 on the pawl arm 65 so that the other arm 62 engages one of the vanes and a pin 64 on such arm disengages the locking pawl 67. Further downward movement of the bar 26 indexes the rotor until the pin 64 clears the pawl 67 which then returns to the locking position, and, in the subsequent return movement of the lever 14 (under spring action), the pin 64 ridesover the pawl 67. A further antispin device is also provided in the form of a spring 69 on the hub 55. The changegiving unit can be removed from the machine for loading and the capacity may be increased by mounting two or more units side-by-side as shown in Fig. 1. Provision may also be made for the lever 14 and associated parts to be capable of being mounted so that the rotor can be indexed in either direction and by either a pulling or pushing movement of the operating bar 26.

Title: Yarn slub detector

Filed: 1960-09-23
Abstract: 918,590. Transistor pulse circuits. BENDIX ERICSSON U.K. Ltd. Aug. 18, 1961 [Sept. 23, 1960], No. 32710/60. Class 40 (6). [Also in Group XL (b)] A self-regulating light-responsive device, responsive to variations in the intensity of light received from a source to deliver electrical output signals indicative of the variations, comprises means to compensate for variations in intensity which exceed a predetermined time duration. The invention is shown incorporated in a slub detector circuit and is used to vary the supply current to the light source L to compensate for slow variations in the intensity of light therefrom due to dirt accumulation or ageing &c. Light from source L is detected, after obstruction by the yarn under test, by a photo-transistor T1 such that a decrease in the detected light produces a positive-going pulse at the emitter of T1 for amplification in a negative feed-back (R4, C1), variable gain (switch S) amplifier T2. The negative-going collector output of T2 is then fed via negative clipping diode D2, across C3 and R8 to the input of T3 such that short slub pulses are too short to change the potential across C3 and do not change the potential of the emitter of T3. Long pulses, however, due to dirt accumulation on the source &c. have time to charge up C3 and produce a negative-going pulse at the collector of T3 which in turn increases the current through T4 and the source L. The circuit also includes means, whereby a slub may be cut out of the yarn or marked, comprising a transistor T5 normally cut off by a bias from RV and input Y and fed, via differentiation network C4, R13 with the output of T2, such that only those pulses having sharp rising edges switch on T5. The resulting positive-going pulse from T5 cuts off normally conducting T6 which in turn increases the current through T7 to actuate a cutting &c. relay RLA. D6, R19 and C6 form a delayed feed-back path to hold T6 cut off long enough for the relay RLA to perform its function.
