Abstract: D 1 : 4-3-Ketosteroids are prepared by heating a 2 : 4 - dibromo - 3 - keto - 5a  - steroid with semicarbazide or a salt thereof in, as reaction medium, a substituted amide of formula R1.CO.NR11R111 (R1 is a hydrogen atom or a aliphatic group containing from 1 to 6 carbon atoms, R11 and R111 are each an alkyl group having from 1 to 4 carbon atoms or together form part of a heterocyclic ring), and decomposing the resulting semi-carbazone, e.g. by heating in an aqueous mixture of acetic and pyruvic acids.  Preferred starting materials are of the formula: <FORM:0788306/IV (b)/1> in which R1 is a ketonic oxygen atom or a hydroxyl group, R2 is a hydrogen or halogen atom, R3 is an acyl group and R4 is hydrogen or an acyl group.  Specified amides are N : N-dimethyl acetamide, N : N-dimethyl formamide, N : N-dimethyl valeramide, N : N-diethyl formamide, N : N-dipropyl formamide, N : N-dibutyl formamide, N-formylpiperidine and N-formylmorpholine, and the reaction is normally carried out at between 50 DEG  and 180 DEG C., preferably between 80 DEG  and 100 DEG  C.; a small quantity of water, up to 10 per cent, is preferably present in the medium.  In examples: (1) to (3) 2 : 4 - dibromo - 4 : 5a  - dihydrocortisone 21-acetate and semicarbazide or its hydrochloride are heated in aqueous dimethyl formamide, or aqueous or anhydrous dimethyl acetamide, the solvent evaporated and, after treatment with pyruvic and glacial acetic acids, crude 1 : 2-dehydrocortisone acetate is extracted with methylene chloride and if necessary re-acetylated with acetic anhydride-pyridine; (4) 2 : 4-dibromo-4 : 5a -dihydrocortisone 17 : 21-diacetate similarly yields crude 1 : 2-dehydrocortisone 17 : 21-diacetate.

Abstract: 412,383. Road - sweeping apparatus. ALIBERT, J. F. G., 25, Belgrave Square, Rathmines, Dublin. April 25, 1933, No. 12100. Convention date, May 2, 1932. [Class 107.] A road-sweeping machine is provided with an auxiliary rotary brush and a trough for conveying to a receiver the row of detritus left by the main sweeper, the brush and trough forming a unit adapted to be mounted on or connected to the machine. In the form shown, the auxiliary brush is of the caterpillar type and passes around two rollers 16, 17, carried respectively by frames 9, 8. The frames are mounted on a tubular spindle 7 secured to the axle 5 of the rear wheel 6 of the machine. The upper frame 8 is rigidly secured in position by two stays 10, 11, and the lower frame is angularly adjustable about the spindle by an adjustable tie rod 13. Such adjustment produces a corresponding movement in the trough 32, which is suspended by links 34, 35, from the frames. The belt is driven by mechanism comprising a toothed wheel 28 on the wheel 6 meshing with a toothed wheel 29 on a shaft 30, the latter being connected by a chain 31 to the shaft 14 of the roller 16. The brush comprises parallel belts or chains 18 carrying transverse bars 19 adapted to receive bunches 20 of bamboo or piassava. Metal plates 23, Figs. 4 and 5, secured to the bars form, with recesses 22, longitudinal channels whereby the bars may be slidden over guiding pieces 25 riveted to the belts 18. Each guiding piece may be provided with a positioning device comprising a spring-pressed stud 26 adapted to engage a recess in the bar 19. The Specification as open to inspection under Sect. 91 comprises also a modification in which the caterpillar brush and trough are carried by a forked frame which is connected to the rear of the main sweeping machine by a universal coupling. The rear end of the frame is supported by a wheel, the shaft of which is connected by gear wheels and chains to the lower roller of the brush belt. Rollers on vertical axes are mounted on the frame and, by contacting with the kerb, guide the frame in its movement along the road. This subject-matter does not appear in the Specification as accepted.

Abstract: 331,945. Callender's Cable & Construction Co., Ltd., and Bennett, P. M. April 19, 1929. Borehole apparatus.-A tool for enlarging boreholes in the ground comprises a tube and an inner rod positively controlling a linkage associated with cutters, the linkage comprising members pivoted together and to upper and lower heads, and the rod causing relative movement between the heads to force the cutters outwardly into operative position. In Fig. 1, a tube 1 is supported by a member 16 with rollers 17 and carries pivoted cutters 8 which have a pin and slot connection 10 to the connected ends of pairs of links 11; the opposite ends of the links are connected to upper and lower nuts 6 on oppositely threaded parts of a rod 2 whereby, on rotation of the rod, the cutters are expanded or retracted. The whole device is rotated by power or by handles 15. The cutters may be formed of T or L shape. In Figs. 3 and 4, an outer tube 33 has threaded openings 35 for adjustably securing it to the member 16, and contains an inner tube 27 and rod 26 to which are connected the upper and lower ends respectively of connected pairs of cutters 22; the tube 27 has keys 36 engaging ways 39 in the tube 33. A nut 29 engages a threaded part of the rod 26 and may be secured to the tube 27 by pivoted bolts 31. Further, collars 40, 44 may be connected to the tube 33 and rod 26 and connected by rods 42 to prevent relative longitudinal movement of these parts. In use, with the nut 29 free as shown in Fig. 3, the nut may be moved downwardly to move the tube 27 and thereby expand the cutters whereby, on rotating the device, as by means of a tommvbar engaging slots 47 in the upper end of the tube 33, a conoidal enlargement is produced with the wide part at the bottom: the nut may then be fixed and the cutters collapsed by rotating the rod 26. Alternatively, the collars 40, 44 and rods 42 may be removed and the tubes 27, 33 locked by pins inserted into registering apertures 48, 49, the cutters then being expanded or collapsed by rotating either the nut 29 or the rod 26: a conoidal enlargement with the upper part wide is thus produced. The operations may be combined. Means may be provided to indicate the amount of expansion of the cutters.

Class 20(4) [Also in Group XIV]  A building block for use along the top of a wall 23, Fig. 5, comprises a platform 10 for supporting a rafter or a wall plate 11 which supports the rafter 12, and a forward part 13 of the block which forms a raised portion providing a downwardly inclined face forming a continuation of the sloping roof. The sloping face has a number of cross ridges 15 which engage ribs 33 on the tiles 34 to support the latter, the uppermost ridge being duplicated at 39 to allow for variation in the sizes of the tiles 34. A slot 31 receives the felting 32 covering the roof rafters 12. For use over a window the channels 38 formed in adjacent blocks are filled with reinforced concrete. When employing larger tiles the lower ridges 15 may be unused. The side faces of the block may be stepped along the forward portion as at 45, Fig. 3, to provide channels between adjacent blocks. A system of grooves 40-44 and 46 are formed in the side faces of the block the groove 41 being located over the cavity 22 of a double wall 23 when the block is in position. In a modification the block instead of being provided with a cavity 36, has its underface flat and a throughway is formed from side to side of the block. The gutter 29 may be secured to the block by brackets and clips which engage the block (see Group XIV). In a modification, Fig. 1, the channel 38 is omitted, the vertical groove 21 terminating in a shallow channel 17 adjacent the inclined rear face 14 of the raised portion 13. The gutter 29 is held by brackets 28 through which screws 30 pass into wooden plugs 27 held between recesses 26 in the side faces of each block.
