Abstract: 580,198. Bearings etc.; lubricating. BRITISH TIMKEN, Ltd., and BOWEN, C. A. March 2, 1945, No. 5216. [Class 12 (i)] [Also in Group XXII] An axle box for an antifriction bearing comprises an outer frame attached to a barrel 1, Fig. 3, by longitudinally extending gusset plates 8 welded at their inner and outer edges to the barrel and to the outer frame. The axle box is constructed by welding to the barrel 1, the hollow tie bars 9 which are sealed off by the gussets 8, assembling the barrel 1, end plates 2, side plates 3 and gussets 8 by the aid of locating rods passed through holes in the end plates, welding the parts together, and then welding the remaining tie bars 9, adapted to receive bolts 10, in place. The side plates, 3, are lined with plates 5 welded at their edges 5b and spot welded at 5a, the flanges 4 of the end plates being similarly lined by plates 6 welded at their edges 6b and spot welded at 6a. The end plates have projections 14, Fig. 1, to which are welded channel shaped members 13, joined by a member 15, these members 13, 15 being also welded to the barrel 1 The barrel has openings 17, 18 which provide for circulation of the oil from a chamber 16, the hollow tie bars 9 being sealed against ingress of the oil and closed by studs if bolts are not used. In the modification shown in Figs. 6 and 8, the box has on top a centrally apertured spring seat 20 shaped on the underside to fit the barrel. This seat 20 is surrounded by a substantially U-shaped portion having side pieces 22a and a back piece 22b welded to the seat and to the end plate 2, a frame stop member 23 being welded to the piece 22b. Side flange plates 21 are welded to the barrel, and front and rear flange plates 24, 25 are welded to the end plate 2 and to the frame stop 25. A flat steel plate 19 is welded to the bottom of the axle box and on the forward end of the axle body is an oil reservoir 26 communicating with the oil chamber 16 in the base through apertures 27.

Title: Improvements in or relating to machines for electrically welding chain links
IPC: B21L3/02
Filed: 1937-02-22
Abstract: 490,065. Welding chains. PARSONS' CHAIN CO., Ltd., and SPENCE, J. T. D. Feb. 22, 1937, No. 5284. [Class 83 (iv)] In a machine for electrically welding chain links including linkholding levers and welding and upsetting jaws, each of the jaws incorporates an hydraulic cylinder and piston or the like for compensating for irregularities in the formation of the links, in order to ensure a simultaneous and uniform upset of both ends of the link irrespective of this condition. Such construction also prevents straining of the weld due to contraction on cooling. Link holding levers 1, which are adjustably mounted on pivots 2 and are operated by cams 4 on a clutch controlled driving shaft 5, are connected by hydraulic cylinders 9 and pistons 10 to welding and upsetting levers 7, which are also mounted on the pivots 2, the levers 1 being held against the cams by springs 6 connected to the levers 7. The cylinders are connected by pipes 11, 12 to an hydraulic pressure supply controlled by valves operated manually, electrically or mechanically. A high pressure may be used during welding and a lower pressure during cooling. The welding and upsetting electrodes 13 are adjustable by screws 14 in the levers 7 and are normally set so that when initially closed on a link, the distance between the electrodes would, in the absence of a link, be less than is actually required to embrace the link. This is effected by securing to the levers 7, bolts 16 which pass freely through lugs 19 on the levers 1 and are provided with adjustable stop nuts 17 for limiting the separating movement of the levers 1, 7. In order to give the operator a visual indication of the necessity for adjustment of the electrodes by the screws 14 to compensate for wear, the lugs 19 are provided with scales 21 and with pivoted pointers 20 connected to the bolts by links 23.

G.-GUSTAV ULLRICH] Feb. 14, 1961 [Feb. 17, 1960; Jan. 5, 1961], No. 5363/61. Heading B5N. A tape measure having linear graduations on one or both sides is made from a pair of continuous plastics strips 1, 2, Fig. 2, supplied from reels 8, 9, to the nip of a pair of rollers 6, 7 and an intermediate layer of parallel inextensible threads 3, the layers being bonded together at the nip by heating the inner surfaces only of the strips 1, 2, as by electric heaters 17 or by one, or two, jets of heated air. The threads 3 are supplied from reels such as 11, spaced apart horizontally or vertically, are advanced by rollers 13 and past guides 12, and are brought into close parallel alignment by thin sheet metal guides 14, Fig. 5. The laminated tape 10 is fed forward under regulated tension by passage over a roller 21, around a suspended and weighted roller 22, and between rollers 23, 24, the arrangement being such that if the tension changes (due for example to slipping of the tape) the roller 22 rises or falls on its pivot arm 25, thereby closing switches and correcting the speed of the rollers 23, 24. To adjust the nip of the rollers 6, 7, the latter roller is mounted for vertical movement as by a screw 18; the roller 6 is positively driven. The strips 1, 2 may be of p.v.c., polystyrene or polyurethane, and the threads 3 of linen, cotton, rayon, or spun glass fibres. The threads may be flattened by passage between the rollers 6, 7. Instead of two strips 1, 2 a single strip folded longitudinally may be used.

Filed: 1965-02-10
Abstract: 1,055,841. Anchor-bolts; nuts. HOWLETT MACHINE WORKS. Feb. 10, 1965 [Feb. 10, 1964], No. 5748/65. Heading F2H. A rock bolt for grouting with concrete in a bore 32, Fig. 3, has at least one longitudinal groove, Figs. 8, 10, containing a tube 63 or a strip 24 to provide a conduit for venting air from the bore or, in the case of Fig. 10, one conduit may be used to introduce grout to the inner end of the bore for initial anchoring. The tube or strip is secured by rolling-in the edges of the groove, deforming the edges at spaced intervals or, if the tube is of synthetic resin, by gluing. For filling at least the main part of the bore, grout is introduced through a hole 58, Fig. 3, in a nut 43 to pass into the bore 32 around the bolt 11 through a recess 54 in the nut and a hole 52 in a bearing plate 42. Air passes from the inner end of the bore 32 through the tube 16. Before grouting, the bolt end is anchored by turning the bolt to move a wedge-nut 47 downwardly to. spread two parts 51 of an expansible member 48. Instead of the wedge anchor, grout may be used to anchor the bolt end before grouting the whole bolt. One conduit 64, Fig. 10, terminates just beyond a flange on the bolt near its inner end, Fig. 9 (not shown), so that grout is introduced through the conduit to the bore end beyond the flange while air is vented through a conduit 66. When the grout anchor is set, the main part of the bore is filled with grout through a nut 43 as before and air is vented through the third conduit 67 which terminates before the bolt flange where its groove is plugged to seal the bore end. Joining bolt lengths.-Where the length of bolt is to he greater than the diameter of the tunnel in whose wall the bolt is to be anchored, rock bolts 34, 36 Fig. 11, with ends 44 bevelled to provide communication between the bolt passages, are joined by a pair of split sleeves 71, 72 with external threads of reverse pitch contracted and drawn together by rotating a sleeve 78 with complementary threads. Serrations 76, 77 inside the sleeves grip the bolts 34, 36.

Title: Electric furnace for the production of calcium hydride (cah)
IPC: C01B6/04
Filed: 1922-02-27
Abstract: 176,354. Kiesewalter, A. March 3, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Electrode furnaces. - calcium hydride is prepared by feeding calcium oxide through an electric are supplied with hydrogen and further treating the product with hydrogen below the arc to ccnvert any free calcium into hydride. Lime is fed through an opening B into a furnace chamber A and falls through an arc between electrodes C<1>, C<2>, C<3>. Hydrogen is supplied through the jackets N of the electrodes. The molten hydride, probably containing free calcium, falls into a well O divided by a partition P into two divisions. The hydride overflows through passages S, Fig. 3, into a chamber T and cools in an atmosphere of hydrogen. The free calcium separates at the bottom of the well O, passes under the partition, and is converted into hydride by hydrogen admitted by a pipe R which dips into the well O. The excess hydrogen passes upwards through the arc and finally escapes by an outlet E and may be purified and used again.

Title: Improvements in or relating to phase measuring circuit arrangements
Inventor: GRISDALE GEORGE LAMBERT
IPC: G01R23/00
Filed: 1953-03-02
Abstract: 742,663. Phase measurement. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 7, 1954 [March 2, 1953], No. 5800/53. Class 37. [Also in Group XL (c)] Phase difference is measured by counting the number of oscillations in a wave train of duration equal to that of a rectangular pulse derived from the phase difference. In the radio direction finding system shown signals received from a directional aerial rotated, e.g. at 25 cycles per sec., are passed through a filter 5 extracting the 25 c/s. modulation to an amplitude limiter AL1 producing a squared wave output and a differentiator D1, alternate positive peaks of which trigger a bi-stable circuit DS. Further, a commutator 6 on the aerial rotating shaft produces from a constant potential source V reference phase pulses also applied to the bi-stable circuit DS so that its output to a gate circuit G is a series of rectangular pulses of duration proportional to the phase difference. This gate is opened by alternate half cycles of a square wave derived from the commutator 6 through three scale-of-two counters 7-9 so that gate pulses 3# times per second are passed to a modulator M to which waves from a phonic wheel 10, driven at 25x45 cycles/second from the aerial driver shaft are also passed after amplifying and shaping into pulses at PF. A counter CH counts the number of output pulses from the modulator M (maximum 8x45=360) between successive resets of the counter and may be calibrated directly in degrees indicating the signal direction. Resetting to zero after each count is also effected by the gate pulses after passing through a delay line DL. The output of an omnidirectional aerial may be added to that of the directional aerial to eliminate ambiguity of sense. Alternatively a radio goniometer may be used. In a modification two counters are used, one counting the total number of output pulses from the modulator, the other the number of input pulses, their division giving the phase difference. In a further modification only a portion of the pulse train output of DS is used to form bursts of higher frequency pulses followed by a gap in which the counter is reset to zero.

Abstract: 1,003,368. Modulating laser light. STANDARD TELEPHONES & CABLES Ltd. Feb, 7, 1964 [Feb. 14, 1963], No. 6031/63. Heading H3B. The output of a laser is modulated at microwave frequencies by providing, between the laser active material 1 and one of its reflecting surfaces 3, an electro-optical element 5 within a microwave resonator 6. Element 5 may be a crystal of potassium dihydrogen phosphate. The distance between the centre of element 5 and each reflecting surface 2, 3 must be an integral number of microwave half-periods, and the time of passage of light through element 5 must be small compared with the microwave period. If the laser emits light within a very narrow frequency band, in the absence of any modulation, then the application of an electric field to element 5 detunes the system and prevents oscillation. If the radiation covers a broader band the presence of an electric field splits the light into two components, respectively, polarized in the two principal axes of element 5. The components are separated by a filter 10. In a modification a polarizing filter is placed on each side of element 5, the filters having their polarizing axes at 90 degrees to each other and at 45 degrees to a principal axis of element 5. In the absence of a modulating field no light passes through the system. When an electric field is applied to element 5 linearly polarized light from one filter becomes elliptically polarized and a fraction of the light is transmitted by the second filter.
