Patent GB-588032-A (GB)
Title: Manufacture of esters of tertiaryamino alcohols
Filed: 1944-03-20
Abstract: Esters of dialkylaminoalkanols are prepared by heating the alcohol with an ester of an alcohol boiling below 140 DEG  C. at 760 mm. and a carboxylic acid whose methyl ester boils above 170 DEG  C., in the presence of an alkali metal alkoxide catalyst and at an absolute pressure not exceeding 250 mm., the displaced alcohol being distilled off.  In the example, ethyl p-aminobenzoate and sodium dissolved in diethylaminoethanol are refluxed under reduced pressure and ethyl alcohol removed as vapour and condensed. Excess diethylaminoethanol is then distilled off under still further reduced pressure.  Another tertiary amino monohydric alcohol specified is dimethylaminoethanol. Other esters which may be used are those of methyl, propyl or butyl alcohols and benzoic, diphenylacetic, phenylcyclohexylacetic, salicylic, aminohydroxybenzoic and furoic acids.

Title: Improvements in and relating to clothes washing machines
IPC: D06F37/24
Filed: 1948-02-23
Abstract: 646,403. Washing and drying machines. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 23, 1948, No. 5334. Convention date, Feb. 24, 1947. [Class 138 (ii)] [Also in Group II] In a clothes washing machine a structure comprising a spin basket 7 and a casing 9 containing mechanism for rotating the basket has circumferentially spaced radially extending arms 13 at its lower end connected by spring means 23 to brackets 19 and carried by a support 5 which surrounds the lower end of the structure in radially spaced relationship, the arms also being engaged by friction damping means 26 carried by the support. Each spring means comprises a, pair of tension springs 23 which are connected to an arm 13 (three or more of which are used) through a plate 15 carried by the arm and which has a foot 16 which when the basket is filled for the washing operation engages a rubber buffer 25 at the lower end of the bracket 19. The friction damping means 26 are pressed one on each side of the arm 13 by a U-shaped spring clamp 27 the ends of which engage V-shaped notches 31 in the plates and are held to the plates by clips 32. The clamp is attached to an extension of the bracket 19 between a pair of rubber pads 29, 30 which allow side motion of the clamp but little vertical motion and frictionally restrain movement of the arm 13 in the vertical plane. In use, during the washing operation, the weight of water and clothes in the basket 7 extends the springs 23 and allows the feet 16 to rest on the pads 25 so holding the tub stationary in a vertical position while the agitator 8 is oscillated ; the springs 23 support the major part of the tub weight. For the centrifugal drying operation this arrangement allows the tub to rise when sufficient water has been discharged, so disengaging the feet 16 from the pads 25 ; the tub is then supported solely by the springs 23 and is free to gyrate about its axis of rotation, any such gyration being damped by the plates 26. The feet 16 are disengaged when the tub reaches a speed of approximately 100 R.P.M. at which speed it has passed its first critical speed. Compression springs may be substituted for tension springs. Specification 558,350 is referred to.

Abstract: 1,219,442. Welding by fusion. CONTINENTAL SCHWEISSAPPARATE A.G. 5 Feb., 1968 [6 June, 1967], No. 5617/68. Heading B3R. [Also in Division F4] A flame welding torch for use in build-up welding comprises a handle part 1, a part 2 for feeding powder, e.g. a fine metal powder, and a set of interchangeable burners 3 each of different welding efficiency, each burner including its own double injector adapted to the efficiency of its associated burner, the arrangement being such that, in the assembled state of the torch, the injector projects into a recess of the part for feeding the powder, the recess being connected. to channels for the feed of two gates and a powder and the part for feeding the powder being releasably connected (during build-up welding) to the handle part. The dimensions of and method of attachment of the part 2 for feeding powder to the handle part are the same as the dimensions of and method of attachment of the burners 3 to the part 2 so that the burners 3 may be directly attached to the handle, the powder feed part being omitted, when flame welding without build-up is to be performed. The rate of powder feed is controllable by a lever 13 and the rates of feed of two gases forming a combustible mixture, e.g. oxygen and acetylene, are controlled by taps 8, 9 on the handle part. Each double injector comprises three parts (58, 65, 71) (Fig. 2, not shown) screwed together to define a conical annular chamber (73) in which the gases mix and a further such chamber (67) in which the powder is mixed with the gaseous mixture.

Abstract: 537,574. Yarn-tensioning devices for knitting, braiding, &c. machines. CARTER & CO., Ltd., B. & F., CARTER, B., and CARTER, E. March 29, 1940, No. 5663. [Classes 74 (i) and 74 (ii)] [Also in Group IX] A yarn-tensioning device for a knitting, braiding or other textile machine comprises a fixed open-channelled yarn guide 9 giving free passage of the yarn and a pair of additional yarn guides 13 having external yarn-engaging parts. At least one of the guides 13 may be adjusted to vary the tension in the yarn and fixed in the adjusted position. The guides 13 are arranged on the supply side of the guide 9, and at least one of the guides 13 has its yarn-engaging surface covered with felt, rubber or other material to impose a drag on the yarn. In the form shown, the two guides 13 are mounted upon a bar 12 pivotally mounted about its centre; in a modification the bar 12 is mounted to rotate about the axis of one of the guides 13, so that one only of the guides has its position adjusted. After passing through the guide 9, the yarn or each yarn is passed through an eye in a pin 17 mounted above a contact bar 6, so that upon breakage or undue slackness in a yarn, the pin falls upon the bar to make an electric circuit and stop the machine. Specification 523,781 is referred to.

Abstract: 282,575. Whipp & Bourne, Ltd., and Whipp, F. March 2, 1927. Cut-out arrangements; automatic circuit-breakers &c.- In an automatic control switch of the kind in which the switch is automatically locked from further actuation if it has been operated a given number of times within a predetermined time period the switch arm is positively connected to a stop pawl, feeding step by step a tooth segment displaceable at a predetermined rate of speed in the opposite direction, the limit of travel of the segment being adjustable to lock the switch in an inoperative position. In the construction shown the switch arm 3, operated by toggle linkage 6, 7 connected to a shaft 8, oscillated by hand or electromagnetic means, rotates about the pivot 4 to rock an arm 9 about the same pivot thereby moving forward a pawl arm 10 for engagement with a toothed segment 15 pivoted at 16 and connected at 17 to the piston of a dash pot 18. The segment 15 has an extension 20 which engages a pin placed in one of a series of holes 19 in a plate to adjust the number of repeat times which the switch may be operated. If desired, the extension 20 may have switch means co-operating with a switch contact to break the circuit of the electromagnetic device attempting to oscillate the shaft 8. The shaft 8 is an extension of the operating shaft of the main circuit-breaker (not shown).

The transmitter and receivers comprise potentiometers 3, 4 the contact arm 1 being connected through a galvanometer 63 and the coil of the galvanometer relay 7 to the contact arm 2, so that upon the arm 1 being displaced the movable contact 16 co-operates with one of the contacts 59, 60, thus completing the circuit to the motor 21, the other pole of which is connected to the centre point of the potentiometer 51, 52. The contact arm 2 coupled to the motor is caused to rotate in the direction of balance of the bridge. Any outof-balance current still flowing after the motor is switched off by the relay 7 opening its contacts, is indicated on the galvanometer 63 at the transmitting point, the scale of which may be graduated to show the difference existing between the positions of the two contact arms. This indication may be used in order to obtain complete agreement of the receiver by the actuation of the transmitter. A single transmitter may control a number of receivers or one receiver may be controlled by two or more transmitters to indicate the sum or difference of the alteration in position effected.
