Title: Manufacture of therapeutic agents
IPC: C07D215/50
Filed: 1930-04-17
Abstract: Aminoalkoxy derivatives of quinoline-carboxylic acid amides are prepared by treating a 2-halogen-quinoline-carboxylic acid amide or a substitution product thereof with an amino-alcohol in the presence of an acid-binding agent.  The preparation of 2-diethylaminoethoxy-4-quinoline-carboxylic acid diethylamide is excluded.  The products possess therapeutic properties.  According to the examples, (1) 2-piperidinoethoxy-4-quinoline-carboxylic acid-anilide is prepared from BETA-piperidino-ethanol and 2-chloro-4-quinoline-carboxylic acid-anilide; the sodium, potassium or calcium compound of the amino-alcohol is employed or an alkali hydroxide is present; (2) 2-diethylaminoethoxy-4-quinoline-carboxylic acid-N-ethylanilide is obtained by interaction of the sodium compound of BETA-diethylaminoethanol with 2-chloro-4-quinoline-carboxylic acid-N-ethylanilide.  In a similar manner are prepared 2-dimethylaminoethoxy-4-quinoline-carboxylic acid anilide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-N-methylanilide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-diisoamylamide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-N-benzylanilide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-benzylamide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-N-ethylbenzylamide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-BETA-phenylethylamide, 2 - diethylaminoethoxy - 4 - quinoline-carboxylic acid-di-(BETA-phenylethyl)-amide, 2-diethylaminoethoxy-4-quinoline-carboxylic acid-ac-tetrahydro-BETA-naphthylamide, 2-aminoethoxy-4-quinoline-carboxylic acid-anilide and 2-diethylaminoethoxy-3-quinoline-carboxylic acid-anilide. Specification 270,339 is referred to.  The 2-halogenquinoline-carboxylic acid amides employed in the manufacture of the foregoing compounds are made by interaction of 2-halogen-quinoline-carboxylic acid chlorides with the appropriate amine.  Thus 2-chloro-4-quinoline-carboxylic acid-N-ethylanilide is prepared from 2-chloro-4-quinoline-carboxylic acid chloride and monoethylaniline.

Title: Crane weight and radius indicator
IPC: G01G19/14
Filed: 1944-06-30
Abstract: 593,794. Fitting weighing-apparatus to cranes. DEHN, F. B. (Martin-Decker Corporation). June 30, 1944, No. 12509. [Class 143] [Also in Groups XIX and XXX] A crane of the kind in which the elevation of a boom 15, Fig. 7, is adjustable (see Group XXX), has an indicator which indicates the radius of the boom (defined as the horizontal projection of the boom), the load supported by a hook 27 and the maximum safe load for any indicated radius. The indicator 35, Figs. 4-6, is operated by two Bourdon tubes 39, 40 which deflect a dial 62 and a pointer 64 respectively. The Bourdon tube 39 is under pressure from the hydrostatic head in a pipe 45 which terminates in a reservoir 65, Figs. 7, 8, pivotally suspended at the outer end of the boom. The boom radius which is dependent on this pressure is indicated by a pointer 70 on the disc 62, Fig. 4, registering with a fixed scale 72. An adjacent fixed scale 73 indicates the maximum safe load for corresponding radii on the scale 72. The Bourdon tube 40 is under pressure from a fluid pressure responsive unit 28 mounted on the cable 24<1> of the hoisting tackle. The unit 28 comprises a chamber secured to the cable 24' by hooks 36 and 37. An open face of the chamber is closed by a flexible diaphragm 31 against which bears a pressure plate carrying a post 33 which engages the cable 24'. The pressure developed in the unit 28 is transmitted by a pipe 34 and is a measure of the load being hoisted which is thereby indicated on the scale 62 by the pointer 64. The hydrostatic head in the pipe 34 causes the pointer to maintain a constant reading on the scale 62 when the latter is deflected by changing boom radius. The Bourdon tube 39 is connected to an adjustable linkage 46, 47<1> which operates a toothed segment 47 which is in mesh with a sleeve 48<1> secured to the dial 62. Springs 58 oppose distension of the Bourdon tube 39 and are shielded from the segment 47 by plates 60. The Bourdon tube 40 is connected by links, 50, 51' to a toothed segment 51 to rotate a spindle 56 concentric with the tube 48<1> and carrying the pointer 64. This movement is opposed by a spring 59 and is adjustable by varying the position of a clamp 53 on a resilient U-shaped portion of the link 50.

Title: A Valve for Controlling the Pressure of a Liquid as a Function of Flow Rate of the Liquid
IPC: F04D15/00
Filed: 1967-03-20
Abstract: 1,183,581. Valves. M. SCHRODER, [trading as H. SCHRODER & CO.]. 20 March, 1967 [18 March, 1966], No. 12854/67. Heading F2V. [Also in Division F1] A valve for controlling the pressure of a liquid as a function of the flow rate includes a casing having an inlet and an outlet, a valve cone arranged in the casing, first and second biasing means for biasing the valve cone against liquid flow through the valve, the second biasing means being stronger than the first biasing means, the biasing means being arranged to act on the valve cone one after the other as the flow rate increases. The valve, which may be used to limit the flow from a centrifugal pump to avoid overloading the driving motor, comprising a throttling cone 3 co-operating with throttling portions 6, 7 of the valve casing 1. In the normal range of rates of flow, mainly a light coil spring 8 is compressed. At higher rates of flow, a strong plate spring 9 is compressed by, say, a further 1 mm., whereafter a distance sleeve 10 abuts a guide 4. In this position of the valve, throttling is effected by the bevelled end 11a of a sleeve 11 in co-operation with a throttling portion 12 of the guide 4, rather than by the cone 3. At a further increase of flow rate, further reduction of the gap between the sleeve end 11a and the portion 12 against the compression of the spring 9 increases the pressure drop exponentially. The bevelled edge 11a is preferably of parabolic contour. A by-pass valve operated conjointly with the throttle valve through a rocker arm 14 comprises a sealing vane 15 which uncovers a by-pass port 16 when the flow rate is low.

Title: Improvements in or relating to hydraulic drives
IPC: B24B47/06
Filed: 1958-04-23
Abstract: 881,361. Hydraulic machines. KLOPP, F. April 23, 1958 [April 27, 1957], No. 12929/58. Class 69 (2). The closed oil circuit of a machine tool, consisting of a reversible, variable-output pump G1 and piston K1, is flushed and leakage from it made up, by liquid from a non-reversible pump G2, which also serves to actuate a reversing valve K4 through a pro-control valve K3. Attached to the piston of valve K4 is a pin 8 on which moves a crank member 9 (Fig. 1a). The crank 9 pivots about a pin 10 whose position on shaft 16 may be altered by a hand wheel 13. A second pin 12 moves in the crank member 9 and determines the eccentricity and hence the output of pump G1. The direction of output of pump G1 is determined by whichever of its two positions valve K4 takes up, and the magnitude of its output is determined by the position of pivot 10. Pump G2 has its output, which is always in one direction, determined by hand wheel 13 so that it is always proportional to the magnitude of the output of pump G1. In the position shown of valve K3, liquid flows from pump G2 via lines 23, 24, 25 to valve K4 and pushes it over to its left-hand position. Flushing liquid then flows via line 26 to the main circuit. Excess liquid is removed from the main circuit via lines 35, 36, 37 and a slight back pressure is maintained in these lines by valve V2. Piston K1 closes contacts A1, T1 as it approaches the end of its downward stroke to actuate a magnet M4 to reverse valve K3. Liquid from pump G2 now flows via lines 23, 24, 39 to the left-hand side of valve K4 to reverse it. As soon as valve K4 starts to move towards its right-hand position, communication between lines 25 and 26 and between lines 35 and 36 is cut off, so that the main circuit becomes completely closed and the energy used in braking piston K1 is transferred wholly to pump G1 and is not lost via line 35. Similar conditions obtain when the piston K1 closes contacts A2, T2 at the end of its upward stroke. K3 and K4 are then again reversed to brake and reverse the motion of piston K1. K2 is a magnetically operated stop-valve. In modifications, in which the piston K1 has differential areas, devices are shown which compensate for this fact when the main circuit is closed during reversal of K1.

Title: Improvements in reversing switches for use more especially on pedestrian-controlled electric vehicles
IPC: H01H25/06
Filed: 1947-05-14
Abstract: 623,694. Mechanical switches, without quick action; controllers. DIAMOND MOTORS (WOLVERHAMPTON), Ltd., and FORD, W. V. May 14,1947, No. 12963. [Classes 38(iii) and 38(v)] The knob 18 of a reversing switch for small electric vehicles is pulled out to complete the motor circuit after rotation to either the "forward" or " reverse" positions. A stem 19 of the knob 18 is slidable in a bush 14 and has a pin 31 engaging a notch 30 in the face of the bush to rotate it in the frame socket 15, the bush 14 being connected to the shaft 13 of the switch drum 11, 12 by a pin 13a. Outward movement of the stem 19 relative to the bush 14 is normally prevented by a detent 27 pivoted at 19a in a slot in the stem and engaging a shoulder 22 in the bush. The detent 27 is connected by a ball joint 28 to a rod 25 which is urged outwardly by a spring 29 positioned between a push-button 23 and a recess in the stem 19, the button 23 being screwed to the rod 25 and slidable in the knob 18. In the central " off " position a fixed pin 37 engages a segmental recess 36 in the face of the bush 14 and the knob 18 cannot be pulled to complete the circuit; however, rotation of the knob to the " forward" or " reverse positions, brings a notch 38 or 39, situated at respective ends of the recess 36, in alignment with the pin 37, and the knob can be pulled to slide the bush 14 and the drum 11, 12 so that the latter engages a spring contact 40 and the circuit is completed. Engagement of the pin 37 in notch 38 or 39 also prevents the knob being turned when the circuit is closed. When the circuit is open the knob 18 and its associated parts may be removed by depressing the button 23, thereby retracting the detent 27 into the stem 19 which is drawn through the bush 14 so that the pin 31 disengages the notch 30, the knob then being rotated to bring the pin 31 into line with a withdrawal notch 41 in a cover plate 16. The knob cannot be removed when the switch is closed, since then the bush 14 is adjacent the cover 16 and the pin 31 cannot disengage the notch 30. A spring-loaded ball 46 locates the bush 14 in the pushed-in positions, and a resistance 45 wound on the switch frame reduces the vehicle speed when running in reverse.

Title: Process for refining vegetable and animal oils and fats
IPC: C11B3/00
Filed: 1934-04-30
Abstract: For freeing animal or vegetable oils and fats from fatty acids which have been converted into fatty acid soaps by the addition of caustic or carbonated alkali, or from mucinous substances, phosphatides, bitter principles &c., the separation of the soaps and other impurities is effected by means of concentrated alcoholic solutions of salts such as sodium chloride, nitrate, formate or acetate which do not form insoluble compounds with the substances to be separated. The alcoholic solution may contain 40--80 per cent of water; as a rule it is maintained practically saturated with the salt; and it is preferred to use such solution at 45--70 DEG  C.  The procedure may be as follows:--the mucins &c., are first precipitated in the oil; sufficient alkali is then added to convert the free fatty acids into soaps; the oil is then actively stirred with the addition of aqueous alcohol and a concentrated salt solution sufficient to dissolve the soap flakes, the mucins &c., being at the same time taken up in the alcoholic salt solution; the soap solution together with the impurities are separated from the oil, and the alcohol distilled off before or after addition of mineral acid in order to obtain eventually free fatty acid.  Alternatively, the impurities precipitated in the oil at the pre-refining treatment may be first separated from the oil; or such treatment may be omitted, the crude oil being directly subjected to the treatment.  Treatment with alcoholic salt solution may be employed for the purpose of separating the mucins, phosphatides and bitter principles from the crude oil prior to its neutralization, such impurities being coagulated in or extracted from the oil which separates quickly.  The addition of the alcoholic salt solution may take place before or during the refining, or before, during or after the neutralization; and the alcohol and the salt in the form of an aqueous or alcoholic solution, may be added separately and if desired at different stages of the process. Soap stocks which have been freed from the bulk of the oil by decantation, may be subjected to the process. Before extraction with alcoholic salt solution, the soap flakes floating in the oil may be dried by the application of a vacuum.
