Abstract: 1,116,495. Worm gearing. HOUGHTONSZEGO LABORATORIES Ltd. 16 March, 1967 [16 Dec., 1965], No. 53376/65. Heading F2Q. In a reversible worm gear, drive is transmitted between a worm 8 and a worm wheel 1 by recirculating balls 15, which roll in a helical groove 13 of semicircular cross-section and in a return channel 14 extending through the body of the worm and opening into the two ends of the groove 13, and engage semicircular section tooth gaps 12 in the worm wheel. A member 7 surrounding the worm retains the balls in the groove 13, the worm-wheel extending through a slot 9 in member 7 to mesh with the balls. Guides (18) (Figs. 6-8, not shown), bolted to flats 16, 17 of the worm 8, smooth the deflection of the balls from the groove 13 into the channel 14 and vice versa. Alternatively, the guides may be formed in rings (25) (Figs. 9, 10, not shown) abutting the ends of the worm (8) and keyed to the worm shaft.

Abstract: 1,263,053. Drilling pipes. E. PASS & CO Ltd. 28 Feb., 1969 [1 Dec., 1967], No. 54697/67 Heading B3C. [Also in Divisions E2 and F2 A hand-operated drilling and plugging device 5 comprises means enabling attachment of the device to a pipe 6, such as a clamp 7 with a screw ferrule 9, an O ring 8, and an adaptor 10; a drilling tube 19, a cutter 25, a plug 26, and a body 12, for sequentially drilling a hole in the pipe and sealing the hole; a valve 11 operable to prevent escape of pressure fluid from the pipe after drilling and before sealing by the plug 26; a feed nut 15 for screw connection with the body 12 and positive feed towards the pipe during drilling; and a releasable fastening, such as a bayonet connection 16, on the feed nut enabling release of the drilling tube 19 from the nut when drilling is completed to allow rapid direct withdrawal of the tube 19 from the device. As shown in Fig. 1, the tube 19 has a squared lower end 22 which fits into a corresponding recess in the cutter 25 which is firmly secured to the tube 19 by a threaded rod 23. In operation, the device 5 is secured to the ferrule 9 by means of the adaptor 10 and a handle 21, secured to the tube 19, is engaged in the feed nut bayonet slot 16 and rotated clockwise so that the feed nut 15 feeds the cutter 25 downwards to cut a hole through the pipe, which is made, e.g., of P.V.C., the cutter retaining the cut-out disc. The tube 19 and cutter 25 are then withdrawn upwardly, the cutter being accommodated within the body 12, above the valve 11, which is then shut, the handle 21 being disengaged from the slot 16 to allow a rapid raising of the tube 19. The body 12 is then unscrewed from the valve 11 and the cutter is replaced by a threaded plug 26, Fig. 2, which has a recess to engage the squared end 22 of the tube 19. The body 12 is reconnected to the valve 11, which is then opened, and the plug 26 is screwed into the ferrule 9, the feed nut in this case not engaging the threads 13. Since the plug 26 only engages the squared head 22 of the tube 19, the tube may be withdrawn by raising the handle 21. The device 5 can then be unscrewed from the ferrule 9 so that a further pipe may be connected to the ferrule 9 as required. In a modification, Figs. 4, 5 (not shown), the handle (21) is fixed to the feed nut (15) which is releasably fastened to the tube (19) by a pivoted latch (33) which is engageable in one of a series of slots (32) in a head (31) of the tube (19).

In a preferred method, the intensity of a calibration stimulus is made the same as that of the standard stimulus, then the intensity of the stimulus to be measured is made the same as that of the calibration stimulus. A differential olfactometer for use in the method comprises two odour injectors 2, 3 with nozzles 2a, 3a having adjustable orifices, mounted on nose-centering support 6, a retractable antidiffusion device 12, 13 associated with each nozzle which in the embodiment shown comprises tubes 12a, 13a movable on actuation of coils 12d, 13d to cover the orifices 2i of the nozzles, for closing the nozzles during the time intervals between periods of presentation of the stimuli, and a respiration detection device controlling by means of an electronic control device the injection of odour through the nozzles. Each injector may comprise a reservoir 2 having a deformable wall which may be a cylindrical or end-wall (wall 2e as shown) coupled to a motor 4 for moving the wall to vary the volume of the reservoir, the movement of the wall providing a flow of the odorous material from the reservoir towards the nozzle orifice 2i. Valved inlet connection 2f may be used to allow flow of gas from an external circulation system into the reservoir and out by the orifice.

Title: Machine for the surface hardening of workpieces
IPC: G05D23/27
Filed: 1970-11-24
Abstract: 1298867 Automatic temperature control PAUL FERD PEDDINGHAUS 24 Nov 1970 [19 Dec 1969] 55890/70 Heading G3R [Also in Division C7] The temperature of a workpiece undergoing a surface hardening process, is maintained at a desired value by controlling the rate of movement of a burner flame relative to the workpiece or by controlling the application of heat in the case of induction heating. The temperature is sensed by a radiation pyrometer. In Fig. 1 a burner 3 is moved parallel to a workpiece 1 by means of a D.C. motor 14 driving a spindle 9 which moves a carriage 5 carrying the burner. The carriage also carries a spray head 4, which directs a quenching spray of water on to the workpiece to cool it rapidly, and an optical pyrometer sensor 15 which senses the workpiece temperature at a point between the burner flame and the spray zone. The sensor 15 output voltage is fed to a temperature indicator 16 Fig. 2 and thence to a D.C. chopper 20 which converts it to an A.C. voltage. This A.C. voltage is amplified in a proportional integral controller 30 wherein it is also compared with a desired temperature value signal from a potentiometer 31. The controller produces an error voltage which is fed via a thyristor unit 32 to control the speed of the D.C. motor accordingly and hence the temperature of the workpiece. In the case of induction heating the error voltage is used to control the output of a frequency converter supplying the induction heater.
