Title: Manufacture of new para-aminobenzene sulphonamide derivatives
IPC: C07D277/52
Filed: 1944-04-14
Abstract: Soluble p-aminobenzene sulphonamide compounds are prepared by the interaction of a 2-(p-aminobenzene sulphonamido)-thiazole with glyoxylic acid or a salt, an ester, an ester semi-acetal, or an ester chloracetal thereof.  If desired the product so obtained is converted into a water soluble salt of the corresponding carboxylic acid.  The reaction may be carried out in water or an organic solvent or an aqueous-organic solvent.  In examples: (1) 2-(p-aminobenzene sulphonamido)-thiazole is added to an aqueous solution of sodium glyoxylate, and the condensation product precipitated by pouring into alcohol.  Treatment with calcium chloride gives the corresponding calcium salt; (2) 2 - (p - aminobenzenesulphonamido) - thiazole is added to an alcoholic solution of glyoxylic acid; (3) an acetic acid solution of 2 - (p - aminobenzene - sulphonamido) thiazole is mixed with an acetic acid solution of glyoxylic acid ethyl ester semi-acetal.  The same compound is obtained by using instead of the acetal, ethoxy chloracetic acid ethyl ester.  The product is finally saponified with 2-N-hydrochloric acid to remove the ester group.  The Specification as open to inspection under Sect. 91 includes in addition to the 2-(p-amino - benzenesulphonamido) - thiazole any chemotherapeutically active p-aminobenzenesulphonamide containing as a substituent in the sulphonamide group a polyheteroatomic heterocyclic residue.  Compounds mentioned include 2 - (p - aminobenzene - sulphonamido)-4 : 5-dihydrothiazole, 2 - (p - aminobenzenesulphonamido) - 5 - ethylthiodiazole, 6 - (p - aminobenzenesulphonamido) - 2 : 4 - dimethyl pyrimidine and p-aminobenzenesulphonamidopyrazines.  Additional glyoxylic acid type components which are included are compounds convertible into glyoxylic acid.  Specified substances include thio-glyoxylic acid, diacetoxyacetic acid, dihalogen-acetic acids alkoxyhalogen acetic acid esters and the like.  An additional example was also included as follows:-Glyoxylic acid in sodium carbonate solution is treated with 2-(p-aminobenzenesulphonamido)-5-ethyl thiodiazole, and the product precipitated by alcohol.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to windscreen wipers
IPC: B60S1/08
Filed: 1958-03-04
Abstract: 833,947. Windscreen cleaners. AVOG ELEKTRO-UND FEINMECHANIK G.m.b.H. March 4, 1958 [June 6, 1957], No. 6983/58. Class 138(1). When a windscreen wiper drive is switched off, the wiper arm is moved to a parking position by a variation in the length of a rotatable crank which rocks the arm, a brake intersecting the path of the crank to engage with it when its length is at its maximum. Attached to a shaft 1 driven by motor 14 are a disc 7 and a spring housing 2. A disc 4 pivots about a bush portion of housing 2 to which it is attached by a spiral spring 3. Disc 4 has an eccentric portion 12 on which a support member 5 which carries crank pin 6 is able to rotate. Relative rotation between member 5 and disc 4 would cause the distance between crank pin 6 and shaft 1 to vary. The crank pin is driven to rotate with the shaft by a slot 8 in disc 7. When in the normal operative condition. Fig. 1, disc 4 and member 5 occupy such relative positions that the crank pin 6 is at or near its shortest distance from shaft 1, the effective length of the crank being sufficient to provide a suitable length of wiping stroke for the wiper blade. To arrest and park the wiper, switch 13 is moved to position A, Fig. 3, de-energizing electromagnet 16, but the motor 14 is kept running by a parking switch 15. The electromagnet releases a pawl which engages abutment 19 on disc 4, preventing the disc from rotating while member 5 continues to rotate with shaft 1 causing crank pin 6 to be moved further away from the shaft and increasing the effective length of the crank. This outward movement of member 5 causes it to engage brake 9 the plunger 20 of which opens parking switch 15 and stops the motor. The brake causes the wiper to come to rest as soon as the parked position is reached. Positions B and C of switch 13 provide a choice of two speeds for the motor. A cable control may replace electro-magnet 16.

Abstract: 661,488. Operating clutches; variable-speed gearing. MORRIS MOTORS, Ltd. Feb. 27, 1950 [March 17, 1949]. No. 7283/49. Class 80 (ii). The main clutch 6 of a motor-vehicle, automatically engaged progressively as the engine accelerates above idling speed, is disengaged at will by depression of a.pedal 7, but the,pedal is latched in depressed position, so as to prevent clutch re-engagement, so long as the idling speed of the engine is exceeded and the speed of the gear-box tail shaft is below a predetermined value. The latch 10, rigid with the armature 11 of a solenoid 14 energised from the battery. 15 through switches 16, 17 in series, is normally retracted by a spring 12. Switch 16 closes when the tail shaft speed is below 150 r:p.m., while switch 17 is closed, by a relay 3 energised by the dynamo 1, when the engine rotates above idling speed (500 r.p.m.). When both switches are closed, the latch 10 is urged to the right and, if pedal 7 has been depressed, the latch engages a hole in a quadrant 8 on the pedal so as to lock the pedal in depressed position until one or other of the switches opens. A second latch 22, co-operating with a notch 21 on the gear-change control spindle 19, is controlled by a solenoid 18 in parallel with the solenoid 14 so as to lock the ,gear lever in neutral unless the speeds are suitable for a gear change. An electro-magnetically operated clutch 6 is shown, energized from the dynamo 1 through a switch 4, closed by the relay 3 above idling speed of the engine, and a switch 5 which is normally closed but which is opened by depression of the pedal 7. An hydraulically operated clutch may, however, be used, the pedal 7 then controlling a valve.

Abstract: 629,554. Lubricating systems. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. March 17, 1947, No. 7349. Convention date, March 28, 1946. [Class 12 (iii)] For the supply of lubricant to points of use in small quantities in liquid form (which may later be applied as an oil mist) an air current carrying oil mist is directed through air ducts each provided at the far end with a very narrow constriction whereby all the oil is precipitated. A main duct 3 supplied from an atomizer 1 with oil-mist carried in an air current has branch ducts 4 and 7-11 the remote ends of which have very narrow constrictions 6 to precipitate the oil which then passes to the point of use. Thus, from the construction 6 of branch 4 the liquid oil passes directly to a bearing 5 ; from the constriction 6 of branch 7 ,the liquid oil passes to a sprayer 28 and from the constriction 6 of branch 8 to a drip-feed lubricator 35 ; branch 9 has a visible feed glass 17 for the drip-feed ; branch 10 has a filter 20 in front of the constriction 6. Each constriction consists of a precipitating nipple 6 with a smali axial bore 13, Fig. 4, opening into a cross channel 14 having a greater crosssectional area. The nipples may be combined with sight glasses, Fig. 4, filters, Fig. 5, spray nozzles, Fig. 6, or drip cups, Fig. 7. As shown in Fig. 4 a sight glass 15 is held between the parts 16, 17 which are screwed together with packings 18, part 16 having an outlet 38. As shown in Fig. 5 a filter 27 surrounds a peripheral groove 24 in the body 19 and with the casing 20 forms an annular chamber 23, body 19 having cross channels 25 and 22, the latter leading to the entry channel 21. The nipple 6 is placed beyond the filter. As shown in Fig. 6 a spray nozzle 28 is connected to the nipple 6 by a sleeve 29. The spray nozzle is formed by the tapered end of a tube 31 on the points 33 of which the oil collects in drops to be carried off by the air current ; a sleeve 34 protects the points 33. The bore of nozzle 28 should be 50 to 100 per cent greater than that of nipple 6. The drip cup 35, Fig. 7, with oil outlet 36 has air-escape holes 37 protected by the flange 39 of a cover 38. To check that all points are receiving lubricant a valve 40, Fig. 1, is opened to put the main duct to atmosphere so that the flow through the branch ducts is so reduced that the oil is no longer precipitated but goes forward as a mist and some of this mist escapes from each point of use and is thus visible.
