Title: Boltless device for spacing at least two parallel spaced-apart conductors
IPC: H02G7/00
Filed: 1976-08-20
Abstract: 1512187 Spacing conductors ALUMINUM CO OF AMERICA 20 Aug 1976 [5 Sept 1975] 34847/76 Heading H2C A boltless device 10 for spacing at least two parallel conductors 20 comprises at least two members 12, 14 which can be brought together to clamp the conductors and two clips 16 to hold the members together in their clamping positions, each clip being of flat metal stock and having a centre portion to engage one member and integral legs 29 with planar extensions 30 to clip over the other member. Each member has indents 22, 24 to receive the clips, indents 22 providing a rectangular portion 25 on which the clip fits while indents 24 provide a wedge shaped portion which opens the legs when the members are brought together. The wedge shaped portion has protrusions 27 over which the extensions 30 engage to hold the members together in a partly assembled condition and ledges 28 against which the extensions 30 engage. In assembling the device the two members are brought into the partly assembled position by hand (the clips 16 having been fitted to portions 25 at the factory) and then clamped together by a tool. As extensions 30 engage surfaces 28 a click indicates that assembly is properly complete. As shown resilient bushings 21 between the clamping members and conductors tension the clips 16. If the clamping members engage the conductors in a metal to metal contact the clips are provided with spring means for tensioning (see Figs. 6, 7, 8, not shown). In Fig. 4, not shown, one half of each clamp is formed by a short member (40) pivoted to the opposite ends of a main clamp member (34). In this case the indents (42, 44) may be extended so that the clip can be fitted at a distance from the pivot calculated to provide the desired compressive force.

Title: Improvements in or relating to a synchronizing device, in particular for gear boxes
IPC: F16D23/06
Filed: 1953-12-16
Abstract: 749,210. Positive clutches. SOC. DE CONSTRUCTIONS MECANIQUES CHENARD & WALCKER. Dec. 16, 1953 [Dec. 31, 1952], No. 35026/53. Class 80(2) To synchronize the engagement of ratio selecting positive clutches in a variable ratio gear, friction clutches are first engaged to pivot locking members and thereby prevent the engagement of the positive clutches until synchronism has been obtained. As shown, a dog sleeve 4 is splined for rotation with a shaft 1, and is moved axially to engage friction synchronizing clutch cones 22, 23 with coacting cones 20, 21 secured to pinions 9, 10. The cones 22, 23 are carried on clutch members 27 which contain balls 37, spring biased into grooves 38 in the dog sleeve 4 to transmit the axial movement of the latter to the clutch members 27 and cones 22, 23. The clutch members 27 are carried by pins 48 fast with the dog sleeve, and have slight rotational freedom relatively thereto. Three of the pins 48 carry pivoted levers 45. On initial axial movement of the dog sleeve 4, the synchronizing cone 20 or 21 is engaged and the difference in rotational speed of this cone and the member 27 turns the latter relatively to the dog sleeve 4 to pivot the levers 45, so that each of them engages one or other of balls 50, which are thus pressed into one of the grooves 38. Further axial. movement of the dog sleeve 4 is thus prevented until synchronization has been achieved, when the arms 45 can return to the central position, the balls 50 can come out of the groove 38, and the dog sleeve can be moved again to engage with dog teeth 55 or 56 on the pinions 9, 10.

Patent GB-770650-A (GB)
Title: Improved process for the separation of aromatic isopropyl compounds from phenols
IPC: C07C37/74
Filed: 1953-12-18
Abstract: <PICT:0770650/III/1> A mixture containing a phenol and an isopropyl - substituted benzene or napthalene, e.g. a mixture obtained by the decomposition of an organic hydroperoxide, is subjected to fractional distillation under reduced pressure in the presence of water; the distillate is allowed to separate into an aqueous phase and an hydrocarbon phase, and at least part of the aqueous phase is re-introduced into the distilling system while a reflux ratio of less than 3:1 of the hydrocarbon phase of the condensate is employed.  For example, in carrying out the separation of a cumenephenol mixture under an absolute pressure of 100 mm., a cumene reflux ratio of 0.8:1 is used, and the resulting distillate of cumene contains only 0.02 per cent of phenol.  The separation can also be carried out by introducing into the column as reflux only the aqueous phase of the condensate, while the hydrocarbon phase is completely drawn off as product.  The mixture to be separated is fed through line 1 into an intermediate section of column 2.  A phenol-containing fraction is discharged from the sump of the column through line 3.  Vapours of water and hydrocarbon leave the head of the column through line 5, and are condensed in hea exchanger 6.  The condensate is passed to separating vessel 7.  The water layer passes through pipe 8 into receiver 9; and is then pumped through pipe 11 to the head of the column.  The hydrocarbon layer of the condensate passes through pipe 13 into receiver 14; this hydrocarbon can mostly be withdrawn as substantially phenol-free product through pipe 15, whilst a smaller portion is pumped through line 17 to the head of the column as reflux.  The reduced pressure in the system is maintained by vacuum pump 21.  The process may be used for the separation of p-cymene from p-cresol, and of beta-isopropylnaphthalene from beta-naphthol. Specification 768,941 is referred to.

Abstract: 1,021,854. Substation circuits. WESTERN ELECTRIC CO. Inc. Sept. 20, 1962 [Sept. 29, 1961], No. 35793/62. Headings H4K and H4R. An anti-sidetone circuit comprises a transmitter 1 connected in the emitter circuit of a transistor 2 which is biased by Zener diode 6. A voltage divider 8, 9, 10 is connected between the collector and base of the transistor and receiver 11 is connected to the transmitter and to point 13 on the voltage divider through blocking capacitor 12. Components 8, 9, 10 are chosen so that when transmitter 1 is in use substantially no signal is applied to the receiver 11. Zener diode 6 stabilizes the base voltage of transistor 2 and hence the current through the transmitter to eliminate the effect of line voltage variations on the output of the transmitter. The collector circuit of the transistor presents a high impedance for incoming speech signals which are thus passed through the capacitor 12 to the receiver 11. Part of the signal current then passes through the emitterbase junction of the transistor and is amplified and applied to the receiver to offset the power dissipated in the transmitter.
