Teeth 36, Fig. 3, on spindle 17, co-operate with similar teeth on the input shaft of head 9, and the input shaft is coupled to the spindle by a pivotable lever. 37 actuated by movement of a cam 41 carried on boring spindle 18 of the machine tool. Two pulleys 42, 43, Fig. 4 are biased by a counterweight 46, and a flexible tube 47 wound on to the pulleys enables lubricant to reach cutter head 9. A damper 51 is provided and locks member 22 in its adjusted angular position. Instead of using a tool head 9, tool 8 can be connected directly with spindle 17 without members 15, 22 being removed, Figs. 13, 14 (not shown). Several interchangeable cutter heads may be provided, each of which is carried by a tool store. The latter comprises a polygonal frame 53, 54, 55, Figs. 5, 7, and four screwing-up heads 155 driven by motors 156. In operation, the headstock is moved up to a frame and the heads 155 engage bolts 57 carried by a cutter head 9. Further displacement allows cam 60 to actuate a switch 58 which starts motors 156 and the bolts are screwed into member 22. The cutter heads are of various types, Figs. 8, 9, 10, 11, 12 (not shown), and the machine is programme controlled.

Abstract: 847,101. Gear-finishing; milling-cutters. KRUPALA, J. Feb. 8, 1957 [Feb. 9, 1956], No. 4416/57. Class 83 (3). A method of shaving a gear 3 with a tool 1 having two series of teeth 2, consists in relatively moving the tool transversely to its axis at each end of a traverse, to cause the series of teeth to cut alternately. Thus, in one direction of movement of the gear 8, Fig. 4, the edges 10 of one series of teeth are operative while the teeth of the other series, not being in full mesh, act as guides. The cutter may be in one piece and be sharpened by grinding the groove 25, Fig. 6. Alternatively, it may consist of toothed rings 28, 29, Fig. 7, pinned and bolted to a hub. The teeth may have a rake-angle equal to the helix-angle, or may have a zero rake-angle, as shown in Fig. 10.

Abstract: 977,940. Measuring electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 1, 1963 [Feb. 6, 1962, No. 4596/62. Heading G1N. In a microwave magnetic resonance spectrometer having a cavity for containing a specimen, means for feeding microwave energy to the cavity, and means for applying a modulated magnetic field to the cavity, a calibrator circuit is provided comprising a crystal detector, means for coupling a small fraction of the microwave energy in, or fed towards, the cavity, to said detector, and means for applying a signal to said detector at the modulation frequency of said magnetic field to cause said detector to reflect microwave energy modulated at said frequency. In Fig. 1, a small proportion of the microwave energy from a wave guide 2 is coupled through a phase-shifter 5 to a crystal detector 6 which is connected through a resistor R to earth. When a switch S is closed, current shunted from modulation coil 3 will cause energy reflected from crystal detector 6 to be modulated at the energization frequency of coil 3, so providing a standard value of modulation with which modulation due to a specimen in the cavity, with switch S open, can be compared. In the modification shown in Fig. 2, the input wave guide 11 to cavity 12 contains a directional coupler 13 which diverts a small fraction of the input energy via side wave guide path 18 to the calibrator circuit.

Filed: 1974-02-01
Abstract: 1435883 Cable grips L R STAFFORD 1 Feb 1974 04800/74 Heading F2X A line gripping device which is releasably mountable on a line or cable 12 to support a load comprises an outer or main bracket 14 and an inner or wedge bracket 16, each consisting of two parallel side plates 18, 20 and 32, 34 respectively joined by U-shaped connecting portions 22, 36. The surfaces 24, 38 of these portions 22 36 may be roughened to improve the gripping effectiveness of the device. The wedge bracket 16 can slidably interfit with the main bracket 14. A lever 58 is pivotally mounted via a rivet or pin 56 between the side plates 32, 34 of the wedge bracket 16 and is spring biased by means of a coil spring 76. A key plate 46 is housed in closely fitting slots 30 in the parallel plates 18, 20 of the main bracket 14, the slots 30 being inclined at approx. 22À5 degrees to the connecting portion 22 and the key plate 46 being provided with apertures 48 for retaining elements such as a wire ring (50) (Fig. 1, not shown) and a removable fastener 52. The key plate 46 extends through slots 44 in the side plates 32, 34 of the inner bracket 16, which slots are parallel with but longer than the slots 30. The line or cable 12 is placed between the clamping surfaces 24, 38 prior to the assembly of the key plate 46 and lever 58, after which assembly release of the lever 58 permits it to rotate clockwise about pin 56 under the force of spring 76 whereupon a recess 68 in the end of the lever 58 comes into contact with a side edge of key plate 46 as shown in Fig. 2. The constant force exerted on the lever 58 by the spring 76 will tend to maintain the wedge bracket 16 in a line gripping position. Any added load acting in a clockwise direction on end 62 of lever 58, via a bore 64, will increase the gripping force on the cable 12 and, conversely, rotation as by an operator's hand of the lever 58 in a counter-clockwise direction about pin 56 will effect release of the cable 12, thus enabling the positioning of the device along the cable 12. The device is particularly useful for connecting the life belt of a workman to safety lines but can also be used to position scaffolds, platforms etc. on cables.

The predrying chamber, which is fed with wet sludge through a feeder 7, includes a pair of vertical shafts 10 and 11 rotated in opposite directions by means of gearing 12 and an adjustable speed motor 13. The shafts are provided with inclined blades 14 which, when rotated, act as conveyors to advance the wet sludge downwardly towards the opening 9 in the top of the chamber 2 while disintegrating the sludge and mixing it with the gases from the combustion chamber 2. Relatively cool waste gases discharged from the top of the predrying chamber are fed to the mixing chamber 18 and/or to the inlet of the afterburner 23 via a fan 16 and ducts 17, 34. Hot gases from an auxiliary oil burner 19 can be selectively delivered to the mixing chamber 18, the inlet end of the afterburner, combustion chamber 2 and windbox 3 via ducts 22, 24, 25 and 33 respectively. Combustion air, preheated in a heat exchanger 31 downstream of the mixing chamber 18, can be supplied to the windbox 3 via duct 6, to the auxiliary burner 19 via duct 20, and to the afterburner 23 via duct 26 and branches 27, 28 and 29 having radial or tangential nozzles 30.

A releasable resilient coupling comprises a torque transmitting rubber element 19 housed in a recess 17 in a driving hub 11 and engaging splines 21 on a driven shaft 14. The rubber element 19 may, as shown, be a rubber ring or may be a series of rubber segments. The inner diameter of the ring 19 is smaller than the outer diameter of the splines 21 which deform the ring 19 when the coupling is engaged. The coupling is disengaged by sliding the shaft 14 left until the splines 21 are clear of the ring 19. The ends of the splines 21 are chamfered at 22 to facilitate engagement by sliding the shaft right. The shaft is additionally supported by a second rubber ring 18. The shaft 14 may be additionally splined adjacent the ring 18. The ring 18, 19 may be carried by recesses in the shaft 14 and engage splines on the hub 11. The ring 18 may be omitted and the hub 11 bears directly on the shaft 14.

[Class 74 (ii)] A stocking blank with a French foot produced by knitting the leg and foot as one piece of fabric, and then separating the high heel and side foot part, for the addition of heel parts, working heel parts on to the high heels and simultaneously connecting the loops of the initial courses of the foot parts to the heel by transfer, has one or more of the innermost loops of the foot parts transferred to the adjacent loops of the high heels before the first courses of the heels are knitted so as to strengthen the heel corner. During the knitting of the heel parts the frequency or the extent of the transfer or both may be varied in order to strengthen the connection at highly stressed places such as the heel corner and heel base. In order to facilitate running on of the needle loops of the high heels and the sinker loops of the foot side parts, the initial loops of the latter are formed as slack courses and the courses of both sets of loops are so laid that the loops are positively anchored to the fabric after separation.
