Title: Improvements in or relating to windows
IPC: E06B3/34
Filed: 1961-08-03
Abstract: 915,712. Windows. SAHLERTZ, E. H. Aug. 3, 1961 [Aug. 4, 1960], No. 28171/61. Class 20 (3).  The hermetically-sealed space between the panes 3, 4 of a double-glazed window can be put into communication with a chamber 14 included in or carried by the sash frame 2 to allow granulate material such as small glass beads, which has heat reduction, reflecting and absorbing properties while transmitting light, to enter the space between the panes 3, 4 from the chamber and vice versa. As shown, the sash frame 2 is pivoted about a horizontal axis on pins 12 and the chamber is disposed on the upper side of the sash when this latter is closed and is separated from the space by a valve flap 15 fitted tightly to one plane 3 and extends across and rests upon the top edge of the other pane 4, being weighted by a rod 16 so that when the flap is lifted by a lever system 17, 18, 19, 20, 21, 22, the glass beads 24 will flow into the space between the panes 3, 4. To empty the space, the window sash is reversed, the flap opening under the weight of the rod 16. On righting the sash again the flap closes. The upper wall of the chamber 14 consists of a resilient wall 25 fastened to the inside of the chamber for pressure equalization between the air in the space and that in the chamber, a hole 28 connecting the space above the wall 25 with the external air. The transference of the beads may be by pump action.

Title: Thermo-electrical generator
IPC: H01L37/00
Filed: 1960-08-15
Abstract: 944,874. Transformers; thermo-electric generators. C. F. R. VON KOCH. Aug. 15, 1960 [Aug. 20, 1959; Jan. 18, 1960], No. 28213/60. Headings H1K and H1T. In a thermo-electric A.C. generator, one or more thermocouples is or are intermittently heated, and the thermocouple circuit, which is free from slip rings and periodic switching contacts, comprises a primary winding of a transformer. As shown, Fig. 5, the core A of a transformer comprises three legs, one of which is provided with a secondary winding F while each of the other legs is surrounded by a rotatable thermo-electric ring R. Each ring R, Figs. 6, 7, comprises two dished plates 1 of a first thermo-electric material joined to form a shell having two projecting portions 2, and wires 4 of a second thermo-electric material, each wire being joined to the shell at the peripheries of portions 2 and wound to provide one or more primary turns around core A. Portions 2, which may be provided with corrugations or ribs (not shown), pass cyclically through one or two flames as the rings are rotated in synchronism, thus producing current pulses, the A.C. component of which is available at the terminals of secondary winding F. Points of equal temperature on plates 1 may be joined by highly conductive wires. Fig. 3a shows a thermoelectric ring R comprising four thermo-couples in series, each having a cold junction K and a hot junction W, the latter projecting radially and axially from the ring and being heated by a burner B. If the ring rotates at 12.5 r.p.s. the A.C. produced has a frequency of 50 c.p.s.; a plurality of burners, and/or a different speed of rotation, may produce a different frequency; moreover, lower harmonics of the fundamental frequency may be utilized. The portions of the ring R in the vicinity of the heated zone may be heat-insulated as by an envelope I. In the modification shown in Fig. 4b a larger number of thermocouples, e.g. twenty-four, form the ring R, the hot junctions W projecting axially from the ring and being heated by a burner through an aperture in a heat shield S. Rapid cooling of the hot junction after the heating period is achieved by radiation and convection, by thermo-electric cooling by the current which continues to flow immediately after the heating period, and by forced cooling, e.g. by air or water. The ring R may be rotated by the pressure of gas emitted by the burner(s), or by an electric motor, preferably supplied with the harmonics of the generated A.C.; or excess heat produced by the burner(s) may drive a propeller to rotate the rings and/or circulate cooling air or water. Alternatively, the rings may remain stationary, the intermittent heating being produced by pulsating flames, a rotating shield, &c. The highest temperature attained by the hot junction should be higher than the material of the junction could withstand continuously, and should be over 1000 C., preferably at least 1500 C. and, if possible, over 2000 C. The thermo-electric materials used in the generator may consist of metal, alloy, metal compounds and semi-conductor material.

Title: Manufacture of aluminium and iron complex salts of the 4:4:4-trihalogen-trityl halides and of 4:4:4-trihalogentritanols
IPC: C07C25/18
Filed: 1957-09-09
Abstract: 4:41:411-trihalogentritanols and aluminium or iron complex salts of 4,41,411-trihalotrityl halides are prepared by treating a 4-halogen-benzotrihalide with an excess of a halogenbenzene in the presence of approximately an equimolecular amount of aluminium chloride of ferric chloride first at a temperature between - 10 DEG and +5 DEG C. and then at a temperature in the range 50 DEG -60 DEG C.  The metal complex salt crystallises out from the isomeric compounds and resinous by-products, which remain dissolved in the excess halogen benzene, and is hydrolysed to give the pure tritanol. In examples (1) 4-chlorobenzotrichloride in chlorobenzene is added to a suspension of aluminium chloride in chlorobenzene below 0 DEG C., the mixture is stirred for 15 hours at - 5 DEG C. and 20 hours at 55 DEG -60 DEG  C.  The resulting 4,41,411-trichlorotrityl aluminium tetrachloride is filtered off and hydrolysed to 4,41,411-trichlorotritanol.  When 4-bromobenzo trichloride is similarly reacted 4-bromo-41,411-dichlorotrityl aluminium tetrachloride is obtained and by using bromobenzene is place of chlorobenzene 4,41,411-tribromo-trityl aluminium tetrachloride is obtained.  Specification 800,857 is referred to.

A mobile hydraulic press for straightening support sections in underground mining comprises a lower part 2 which serves as an abutment for a press ram 3 and is connected by buckstays 4 to an upper part 1 carrying the pressure-medium pump 20, together with its drive 21, and the press cylinder 19, the upper part being adapted to be clamped to the upper ends of the buckstays when in its operative position and to be lowered by a considerable amount in relation to the ends of the buckstays after release of the clamping elements. The lowering of the upper part permits the overall height of the press to be reduced by approximately 20% to enable the press to be more easily moved on a car through the mine galleries. The lower ends of the buckstays are secured to the lower part 2 by annular discs 9 in grooves in the buckstays bearing against surfaces on the lower part and cap-like nuts 10 bearing against surfaces 11. The upper part has lateral projections 18 which receive screws 17 having reduced ends engaging recesses in a clamping bar 16 which bears on the upper ends of the buckstays; tightening of the screws moves the upper part 1 upwardly to engage collars 13 on the buckstays. When the upper part is thus clamped, the ram 3, which has a pressing member 5 guided by rollers 6 engaging the buckstays, can be moved downwardly to straighten a mine support positioned between a die 7 carried by the ram and a die 8 on the lower part. Release of the clamping screws 17 permits the bars 16 to be removed and the upper part to be lowered; the lowering and raising of the upper part may be effected by the ram 3 and cylinder 19. In other embodiments, the clamping devices may be rockably mounted on the upper part and clamped by hydraulic or pneumatic means. Reference has been directed by the Comptroller to Specification 729,276.

[A]so in Group VIII] A skiving and/or splitting machine comprising feeding means for a workpiece and control means for regulating the speed of the feeding means is characterized in that the control means includes two clutch members, one being connected to driving means and the other being connected to the workpiece feeding means, a control member adapted to urge the clutch members together, and a resilient intermediate member arranged between the control member and one of the clutch members. The skiving machine shown comprises a cylindrical knife 7 the shaft 6 of which is driven from an electric motor 3 through a belt 4 passing over a pulley 5 having further grooves 8 from which is driven, by means of a belt 9, an idling pulley 10 which runs on ball bearings 11 at the end 12 of a shaft 13 from which a feed roller 14 is driven. The shaft 13 runs on ball bearings 17, the outer ring of which is held in a support 16 by means of a cup - shaped stationary disc 19. Mounted on a keyway 20 in the shaft 13 is an axially-slidable control member 21 which is movable in one direction to press a braking disc 23 against the stationary disc 19 and movable in the opposite direction to gradually compress a leaf spring 24 thereby pressing a clutch disc 26 against the idling pulley 10 which acts as the driving clutch member. A driving spring 28 is arranged between the braking disc 23 and the inner ring 27 of the ball bearings 17 while a safety spring 30 is arranged between the clutch disc 26 and the inner ring 29 of the ball bearings 11. The distance between the pulley 10 and the clutch disc 26 is adjustable by means of a nut 31. A pivotally-motinted brake lever 33 has mounted at the end of its shorter arm a setscrew 34 which acts upon one end of a pressure pin 36, the other end of which bears against the leaf spring 24 and against the control member 21. Acting upon the longer arm of the lever 33 is a brake spring 37 which has a higher spring tension than that of the springs 28, 30 in combination. The end of the longer arm of the lever 33 is connected by means of a ball- and-socket joint 46 to one end of a connecting rod 38, the other end of which is connected to a treadle 39 which, by loosening a clamping screw 40 on the connecting rod 38, can be set up at any position under the machine. The treadle has a locking device comprising a spring 44 having a nose-like extension 42 engageable, when a treadle 43 is depressed, under a catch 41. When the treadle 43 is depressed, the brake spring 37 is compressed and the pressure pin 36 withdrawn thereby releasing the control member 21 so that the clutch disc 26, under the resultant action of the springs 28, 30 and leaf spring 24, will be pressed against the idling pulley 10 until it is driven by the idling pulley without slipping.
