Title: Improvements relating to the ventilation of electrical or other machinery or apparatus
IPC: H02K9/10
Filed: 1923-10-08
Abstract: 226,305. Young, J. W., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 8, 1923. Ventilating electrical and other machines; air, cooling; inlet and outlet ports, arrangements of; valves, actuating.-A ventilating system for electric or other machines, such as an electric generator 1, Fig. 1, comprises an air port 4 communicating with a forked channel 5, one branch 7 of which communicates by way of a chamber 8, containing a cooler 9, with one or more other air ports 2, 3 of the machine, and the other branch opens to the atmosphere. A damper 11 hinged about its lower edge in the forked duct is connected by a rod 13 and resilient links 14, 15 with a damper 12 which is hinged about its upper edge and serves to open the chamber 8 to the atmosphere. The two dampers make equal angles with the vertical and are therefore balanced in all positions. In the positions shown, air passes from the outlet 4 through the cooler 9 and enters the machine again at the ports 2, 3. With the dampers in the other extreme positions the passage 7 is closed and the passages 6, 10 are open so that air circulates freely from the outside. The length of the channel 5 may be reduced if both of the dampers 11, 12 are pivoted about their lower edges. In this case, a balance of the parts may be obtained by a system of cranks and levers, or weights. The position of the dampers may be controlled from a pedestal 26 upon which is mounted a hand-wheel 27 connected through a drum and a rope to projections 31, 32 on the rod 13; the drum may be driven by an electric motor and indicating devices may be provided to show the position of the dampers. A thermally-operated relay controlling visible and audible signals may be provided to indicate when the temperature of the machine exceeds a predetermined limit. In a modification, Fig. 4, the damper in the passage 10 is replaced by a door 37 pivoted vertically about its centre and connected resiliently with the rod 13.

The rake 16 (Fig. 5) of a reclaimer can be traversed along the face of the reclaimer. In the construction illustrated two rakes are provided on corresponding booms 15 shown in plan in Fig. 4 and carried by a single carriage 14 traversed along the reclaimer. Material dislodged by the rakes falls on to a plough 17 (Fig. 5) from which it is removed by rotating wheels 34 (Fig. 4) which deliver it to a conveyer 12 carrying the material along the reclaimer to a fixed conveyer mounted outside the pile area. The booms 15 are supported at their upper ends by cables 36 (Fig. 5) and at their lower ends are connected through hinges 43 to eccentrics 41 which serve to oscillate them. The plough 17 may be raised, when the reclaimer is to be retracted, by tilting the reclaimer carriage 5 about its rear wheels 28: this is effected by rams 45 which lift the wheels 26 from their rails 22. In alternative arrangements the jib 15 may carry an endless driven chain forming the rake, and the jibs may be separately traversed. The inclination of the jib may be varied automatically to provide a steady feed. Wheels 46 (Fig. 4) mounted on jacks may serve to transfer the reclaimer from one set of rails to another.

Abstract: 880,434. Combined sound and picture apparatus. DOMINUS S.ar.l. Aug. 6, 1958, No. 25155/58. Class 40 (2). [Also in Group XX] A method of recording sound for playback synchronously with the projection of a cinematograph film comprises coupling a tape recorder and cinÚ projector for operation by a single motor so that sound may be recorded on the tape while the projector is driven. The particular embodiment described shows a combined instrument, Fig. 2, with detachable lids 94, 95 covering the projector and tape recorder respectively. The projector arrangement is described with reference to Fig. 4 which shows the film spools 15, 16 arranged in a common plane on a panel 10, the film 17 passing through a picture gate 22. A common motor 1, Fig. 9, drives a tape recorder mounted on a panel 2. The motor is reversible and drives shafts 20 carrying the sound tape spool 4, 5 via friction-disc clutches and helical spring slip clutches such that the take-up spool only is driven. A capstan 12 positively drives the tape via friction gearing 47, 44, 40 incorporating a stepped wheel 97 on the shaft of the capstan 12 to permit a number of tape speeds to be used. A friction roller 96 may be fitted for the purpose of driving a conventional gramophone turntable.
