Abstract: 932,609. Nozzles. M. WIDENMANN. Sept. 28, 1960, No. 33376/60. Class 69 (3). A jet pipe, particularly for fire extinguishing purposes, has a three-way spherical plug valve 3 within a housing 2 and arranged so that in one position the flow of liquid supplied through a hose coupling sleeve 1 is cut off, in a second position, shown in Fig. 1, liquid flows unimpeded through the pipe 5 to the outlet nozzle, not shown, and in a third position the liquid is fed through inclined slots 16 in an element 4 and thereby whirled so that it leaves the outlet nozzle as a spray. As shown, the slots are formed in a sleeve 4 projecting into the valve housing, and an annular space 18 is provided between the sleeve and valve. The latter has a straight-through hole 6 and a transverse bore 7 leading into it, and when the valve is moved by the lever 8 to the spray position in which the bore 7 faces the oncoming stream, liquid flows about the valve and through the space 18 as well as through the slots. In the cut-off position the bore 7 faces the outlet nozzle. In Fig. 2 the slots are formed in the end of the pipe screwed to the housing and leading to the outlet nozzle, and the pipe, which may be integral with the nozzle, is held in the desired position by a threaded ring 33. The valve is adjusted by a lever 8 acting through a pin 24; the nozzle pipe may be of plastic of high electrical resistance and low heating coefficient, and may include longitudinal and transverse ribs on its outer surface.

Title: Improvements in signaling apparatus
IPC: H04L15/22
Filed: 1932-11-28
Abstract: 391,393. Maintaining defined speeds of motors. SUBMARINE SIGNAL CO., 160, State Street, Boston, U.S.A.-(Assignees of Hart, R. W. ; 128A, Jenness Street, Lynn, Massachusetts, U.S.A.) Nov. 28, 1932, No. 33688. Convention date, Jan. 29. [Class 38 (iii).] A source of direct current is converted into pulsating current which is used to drive a synchronous motor. The direct current is converted by reed 19 which is weighted at 34 and is adjusted to vibrate 27 times a second. The reed carries one of the interrupter contacts 31, 32 and is maintained in vibration by magnet 2. The pulsations charge and discharge the condenser 10 through winding 15 of the synchronous motor 37, which thus rotates with a definite velocity.

Title: Improvements in or relating to thrust bearings for marine engines
IPC: F16C19/10
Filed: 1922-12-09
Abstract: 211,992. Whelan, W. Dec. 9, 1922. Ball bearings.-Marine horse-shoe shaped thrust' shoes a which co-operate with thrust collars c on a shaft b are provided with ball bearings of the type in which the ball races have the form of closed curves which do not encircle the shaft, and in which the balls are retained by slotted plates, and come into and out of contact with the bearing surfaces on the shaft. As shown in Fig. 1, the ball races d, which are cut either in the thrust shoe itself or in steel blocks recessed therein are of kidney shape, and the balls are retained in the races by plates e, f, g. Projections h or dowel pins may be fitted to the thrust shoe to permit exact replacement of the plate e after removal. The races may be deepened and widened at the parts'not concentric with the shaft and the plate g may be removed when it is necessary to remove or inspect the balls. The thrust shoe may have only one bearing surface, or it may have a bearing surface on both sides, each engaging a separate thrust collar. In a modification, Fig. 4, two sets of races, each comprising a ball race surrounded by another race, are arranged on each side of a thrust shoe and a single plate p for two plates q permit of the removal of the balls. In a further modification two kidney-shaped races only are arranged on each side of a thrust shoe. Specification 153,961 is referred to in the Provisional Specification.
Patent GB-650887-A (GB)
Title: A process for the preparation of unsaturated aldehydes
IPC: C07J13/00
Filed: 1947-12-22
Abstract: Aldehydes of the formula R1R2C=CH-CHO are prepared from compounds of the formula R1R2C(OH)-CH=CH-OR3 by treatment with an acidic reagent resulting in intramolecular conversion; R1 is hydrogen or a hydrocarbon residue which may be substituted, R2 is a hydrocarbon residue which may be substituted and R1 and R2 may be connected by a ring system; R3 is an alkyl, aryl or aralkyl group.  The starting materials may be obtained from ketones R1R2CO by (1) treatment with a metal derivative of a compound CH=C.OR3 to give R1R2C(OH)-C­ C-OR3 followed by reduction, or (2) treatment with a metal derivative of a compound CH2= CH-OR3.  In examples, (1) phenoxy-acetylene is converted into its Grignard compound with ethyl magnesium bromide and reacted with the C18 ketone of the Vitamin A series.  The resulting acetylenic carbinol is catalytically hydrogenated to the corresponding ethylenic carbinol and the latter hydrolysed to Vitamin A aldehyde with oxalic acid; (2) a Grignard compound is prepared from 1-ethoxy-2-bromethylene and magnesium and reacted with C18 ketone as in (1), the product being hydrolysed to Vitamin A aldehyde; (3) 1-ethoxy-2-brom-acetylene is converted into its Grignard compound with ethyl magnesium bromide and reacted with acetophenone.  The product is hydrogenated and hydrolysed with hydrochloric acid to give b -methyl-cinnamic aldehyde; (4) ethoxy-acetylene is converted into its Grignard compound with ethyl magnesium bromide and reacted with b -ionone. The product is purified by chromatography and hydrogenated and hydrolysed as in (1) to give b -ionylidene-acetaldehyde; (5) the Grignard compound of ethoxy-acetylene is treated with dehydro-androsterone acetate and the product hydrogenated and hydrolysed with hydrochloric acid, yielding 3-acetoxy-pregnadiene-5 : 17-al-21.

Title: Improvements in automatic tack welding apparatus or the like
IPC: B23K9/10
Filed: 1931-12-07
Abstract: 377,548. Arc welding. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 7, 1931, No. 33902. Convention date, Dec. 19, 1930. [Class 39 (iii).] In an apparatus for automatically forming tack or interrupted welds, in which an arc welding head is moved along the work by a motor-driven trolley, the welding current is automatically alternately switched on and off by a contact actuated from a gear controlling the welding and non-welding movements of the trolley so as to obtain an interrupted weld while still retaining the forward movement of the trolley. The welding head 2 is carried by a trolley 4 traversible alternately by each of a pair of motors 10, 11 driven at different speeds and connected by worm and differential gear. The motors are connected by gearing with a drum 12 having a cam sleeve 13 which operates a switch 14 to energize a relay 15 so as to close a contact 16 and thus stop the motor 11 which traverses during the non- welding period. Closing of contact 16 energizes the field 300 of the electrode feed motor 30 and also the field 400 of the welding generator 40 and energizes a circuit through contact 500 and relav 31 to raise contact 310 and thus energize the armature 301 of the feed motor to feed the electrode 3 to the work. When electrode engages the work the welding circuit is energized and relay 51 draws down contact 500, thus cutting out relay 31 and putting in relay 32 to close contact 320 and thus reversing the feed motor to strike the arc. The relay 51 also closes contact 502 to put the motor 10 into action to traverse the head and also closes contact 501 to energize relay 50, which acts on the contact 500 in opposition to the relay 51 to keep the arc length constant. When switch 14 is opened through the contact gear, the motor 10, welding current and electrode feed motor are cut out and motor 11 put in.

The end of the member is Venturishaped and forms with the casing O a further annular passage M through which liquid is forced. The liquid is supplied by a pipe F and passes to the passage L through holes J. Shims R and Q enable the passages L, M to be adjusted. Specification 432,191 is referred to.
