Title: Octogen from hexamethylenetetramine by a simplified - nitration process
IPC: C07D257/02
Filed: 1968-12-27
Granted: 1970-11-09
Abstract: Octagen, a cyclic polynitramine of the structural formula: is produced by mixing in a first step, in acetic acid or residual acid, solid hexamethylenetetramine (I), HNO3, solid ammonium nitrate, and acetic anhydride, adding in a second step, HNO3, solid ammonium nitrate and acetic anhydride, allowing the mass to ripen, then separating octogen by filtration, and eventually hexogen by cooling.
Patent GB-1050139-A (GB)
IPC: B23H3/10
Abstract: In an electrolytic machining process, machining takes place intermittently, with the electrolyte between the workpiece and tool being replaced <PICT:1050139/C6-C7/1> in the intervals between machining by pumping action effected by causing the tool 1 to be reciprocated relative to the workpiece 4 by means of a cam 2 and cam follower 3.  Electrolyte passes from a reservoir 7 through a non-return value 8 into the working gap 9 between the tool and workpiece on the downward stroke of the tool 1, and is expelled via a non-return valve 10 on the upward stroke of the tool; the space between tool and workpiece being thus replenished with fresh electrolyte on each reciprocating movement of the tool.  The workpiece may be fed continuously relative to the tool.  The voltage applied may be constant, pulsating, alternating or alternating superimposed with a undirectional voltage, such that high current flow occurs when the tool is in the working position relative to the workpiece.

Abstract: 1,052.433. Floor structures. TECHNOEXPORT, BULGARIA. May 31, 1963, No. 22010/63. Heading E1W. Floor or similar panels 11, 12, Fig. 5, are supported from columns 16 without the intermediary of joists, and are held together by the elements 25 serving to pre-stress the panels in a direction parallel to the plane of the floor, some of which elements extend through passages in the supporting columns. Some of the panels are directly supported by the columns, these panels 12, 13, 14, Figs. 1c, d, e having cut-outs 15 which partly encircle the columns, the columns having temporary support rings 22, Fig. 6 for supporting such panels during the erection proceedure. Other panels, 10, 11, Figs. 1a, b having no cut-outs are supported from panels such as 12, 13 and 14, temporary support means (not shown) being provided for the panels 10, 11 during the erection proceedure. After the joints between the panels are cemented, as at 24, steel cables 25 are threaded through aligned holes in the panels and columns and are placed in tension and grouted. Reinforcement and concrete 26 is then introduced into spaces defined between the cut-outs and grooved sections 21 of the columns 16, the surfaces 23 of the cut outs being inclined upwardly and towards the column so that the columns support the panels through the reinforced concrete 26. The two different sizes of panels shown in Figs. 1 a and b may be employed in many different arrangements to provide structures of various shapes and sizes. Some of the panels are modified to provide staircase panels.

Abstract: 1,084,148. Roller conveyers. NATIONAL GYPSUM CO. Nov. 15, 1965, No. 48386/65. Heading B8A. [Also in Division F2] A multi-deck conveyer apparatus for handling sheet material, e.g. gypsum wallboard delivered to the apparatus from a drying kiln 20, Fig. 1, comprises decks A to H each of which includes driven rollers 22, 60, 70, 72, 80, 90 and 154 to 157, and a power-operated pivoted sheet-aligning gate, e.g. 260, which is moved to its release position simultaneously with energization of a motor driving the rollers 154 to 157. The rollers 22 and the rollers 60 are driven from an electric motor or gas engine 31 through a drive including a chain 26. The roller 60 is connected through an overrunning clutch 62 to the rollers 70, 72 and 80 so that the roller 60 normally drives the rollers 70, 72 and 80 but the latter can rotate faster than the roller 60. The rollers 80 are connected through a second overrunning clutch 96 to the roller 90 so that the drive from the rollers 80 is not normally transmitted to the roller 90 but the latter when rotating at a speed which is greater than the normal speed of the rollers 80 drive these rollers. The roller 90 is connected to the rollers 154 to 157 through a clutch 100, Figs. 8, 9 (not shown), which includes a spring- loaded driving pin 120 manually slidable longitudinally into or out of driving engagement with a hole 118. The rollers 154 to 157 are driven by a motor such as 215, Figs. 2 and 4 (not shown), provided for each deck. Each gate, e.g. 260, is moved by a pneumatic ram. e.g. 286, Figs. 5, 16 (not shown), operated by a solenoid-operated valve, e.g. 286, controlled from a control console 480, Figs. 14, 15 (not shown). The latter has a control panel 484 provided with lamps 486 indicating the decks A to H, and below the lamps are switches 490 for manual selection of the decks operated. A switch 492 provides for automatic sequential operation of the decks. A timer mechanism 494 adjusts the interval during which each deck is operated, and a second timer mechanism 496 adjusts the interval between operation of successive decks. The sheet material passes from the rollers 154 to 157 on to driven rollers 502 which form decks sloping to an endless belt conveyer 510. During operation the clutch 100 is engaged when sheets being conveyed extend from the gate beyond the roller 154, so that the rollers 70, 72, 80 and 90 are driven at the same speed as the rollers 154 to 157.

A motor vehicle headlamp has a parabolic main reflector 1 with a focal point F, a halogen filament light source 3, a translucent cover 2 and an auxiliary reflector 5 which is pivoted at 6 about an axis transverse to the optical axis of the main reflector and has its focus at F 2 . In the position shown the auxiliary reflector produces a main beam. When turned clockwise it produces a dipped beam (Fig. 3, not shown). The auxiliary reflector is less than semicircular in plan to provide an asymmetric beam and may have a screening hood (21, Figs. 6 and 7, not shown) to reduce dazzle when the headlamp is dipped or may have ribs (17, 18, Fig. 5, not shown) situated on its upper edge near the light source to give good light-dark boundaries. In a modification the pivot for the auxiliary reflector lies in a plane normal to the optical axis of the main reflector but is inclined to the horizontal. Thus when the headlamp is dipped, the beam is directed towards the nearside of the road. The cover 2 may be provided with diffusing corrugations on part of its surface. The axial coiled filament may be replaced by a transverse or oblique filament.

Suitable sugars include mono- and di-saccharides, such as dextrose and commercial glucose produced by hydrolysis of carbohydrates, fructose, galactose, mannose, levulose, lactose and maltose, their blends with higher saccharides such as found in corn syrup. The compositions may be used in the preparation of flame-proof and fire-proof resinous binders by mixing at ambient temperature at least 1 part by weight with 1 part by weight of either furfuryl alcohol or a blend or polymer consisting of 95-85% weight furfuryl alcohol and 5-15% weight formaldehyde or other aldehydes such as glyoxal or furfural. Uses.-The blends thus obtained can be used for heat-setting applications on asbestos, particle board, textiles, graphite and foundry sands. The cold and heat-set reaction products are strong adhesives for metal, glass and carbon. In the manufacture of foundry cores and moulds 1-5% wt. of the above resin binder is required for 99-95% wt. of foundry sand such as silica, zircon, chromite or olivine sand. Various additives such as graphite, pitch, olivine flour, boric acid and iron oxide can be added. The cores and moulds when set can be in a rubbery state which can then harden in air after stripping from the boxes. Light alloys, Al, bronze, grey irons and steels can be cast using these cores and moulds.
