Title: Improvements in or relating to dynamo electric machines
IPC: H02K9/00
Filed: 1952-08-13
Abstract: 722,151. Cooling dynamo electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 13, 1952 [Sept. 28, 1951], No. 20359/52. Class 35. The invention relates to the cooling of high voltage stator windings by fluid under pressure passed through ducts in the conductor slots and over heat exchangers. As shown, ducts 14 of lightly insulated poor conducting metal through which gas, preferably hydrogen, is passed under pressure, are disposed between stacks of conductors, and the main conductor insulation is provided by a sheath enclosing the whole assembly as shown in Fig. 7. The ducts may be continued throughout the end windings. Axially disposed gas coolers may be disposed between the stator core and easing and the gas may traverse radial or axial ducts in the stator core. In one form gas passes axially through all the ducts 14 in parallel from one end of the machine to the other in the same direction before passing to the coolers but in another form, gas flows throughout the length of the stator but in opposite directions in adjacent slots, the blower at one end of the rotor passing gas into half of the number of conductor slots, the other slots being fed from the other end. In a third form gas enters all the conductor slots at both ends and flows towards the centre of the machine where the slots, conductors and sheaths are arranged as shown in Fig. 13 over a small part of their length to enable the gas to emerge from ducts 14 and pass into radial ducts at or near the centre of the stator core. Specification 722,152 is referred to. Reference has been directed by the Comptroller to Specification 682,340.

Title: Photometer for measuring total radiant energy at selected angles
IPC: G01N21/53
Filed: 1971-04-19
Abstract: 1298658 Photo-electric photo-meters BECKMAN INSTRUMENTS Inc 19 April 1971 [29 Jan 1970 21 Dec 1970] 20411/71 Heading G1A [Also in Division G2] In a photo-meter in which a laser beam 7 is focused at a point 16 in a test sample 14 and scattered light, after passage through a radiant energy mask 24, is focused on to the aperture 34 of a diaphragm 32 to be received by a detecting system 38, 40, the mask 24 has an annular aperture 26 which selects only that radiation scattered within a predetermined incremental angle #α. Alternatively, the mask 24 may be rotatable and contain a sector only of a full annulus. As shown, the incident beam is further limited by an apertured diaphragm 9, and undeviated radiation leaving the sample is either absorbed or reflected away by a trap 20. The detector 40 may be a photo-multiplier, photo-diode or phototube provided with calibrated attenuators 44, 45 and a filter 38, and the lens 28 may be replaced by a concave mirror or fibre optics. A mirror 47 can be placed in the optical path to enable visual observation or photographic recording of the scattered light pattern. Alternatively a telescope can be placed between the lens 28 and mask 32 for visual observation. The apparatus is used to determine the  scattering or fluorescing properties of a suspension 14 placed in a transparent walled test cell 10, or of a solid, e.g. a photographic film. By using a polarizer 21 and analyser 46 the state of polarisation of the scattered light may be investigated. A measurement of the radiation transmitted through the sample is made by removing the trap 20, the device 25 being an attenuator provided for safety reasons. Wide-angle scattering is monitored either by surrounding the test cell with an annular mirror (52), Fig. 2 (not shown), or by having an additional collecting lens (27) immediately downstream of the test cell, Fig.3 (not shown). Light scattered to one side only of the sample can also be monitored, Fig. 4 (not shown), as can back-scattered radiation, Fig. 5 (not shown), by using plane mirror arrangements to irradiate the sample at the required angle. A number of masks 24 having different aperture sizes may be mounted on a rotatable or slidable holder for investigating scattering effects at different angles, and the apertures in diaphragms 9 and 32 may be adjusted in a similar manner. The apparatus may be used in a dual beam device, the other beam being the conventional reference beam.

Title: Apparatus for indicating synchronism and relative phase of and engaging and disengaging claw-or tooth clutches
IPC: F16D23/10
Filed: 1937-07-23
Abstract: 482,568. Operating clutches ; indicating synchronism of clutch parts. DEUTSCHE SCHIFFUND MASCHINENBAU AKT.-GES. July 23, 1937, No. 20437. Convention date, July 24, 1936. [Class 80 (ii)] Means for indicating when the parts 18, 19 Fig. 1, of a claw clutch are rotating in synchronism and are in register, so as to permit engagement without shock, comprises a pointer 16 geared to the planet carrier 13 of a differential toothed gear, the sun gears 7 and 8 of which are positively geared to the clutch shafts 1 and 2 so as to rotate in opposite directions. The arrangement is such that one revolution of the pointer 16 corresponds to one revolution of the shafts 1 and 2 relative to one another, so that when the pointer is at rest opposite a fixed mark 17 the clutch parts are in register and in synchronism. Engagement and disengagement of the clutch is effected, through a pivoted yoke 20 engaging the sliding claw member 18, by a double-acting steam, air, or gas motor 24, 25, Figs. 2 and 3, controlled by a slide valve 6. The latter is interconnected with the piston rod 23 through a lever 32 so as to be returned to mid-position at the end of either stroke of the piston 24. The rod 23 is connected to a second piston 27 working in a cylinder 28 controlled by a slide valve 29 connected to the valve 26. The inlet and exhaust sides of the valve 29 are connected, respectively, to the discharge and suction sides of a hand oil pump 30. During either stroke of the piston 24, oil is displaced from one end of the cylinder 28 to the other through the pump 30, but towards the end of the stroke a dash-pot action is set up as the valve 29 moves towards mid-position. The pistons can be locked in either end position by engaging one or other of two pins 33 with the crosshead 34. These pins are operated by a piston 35, to either face of which oil can be supplied, on operation of the pump 30, by means of a control valve 36. The pins can also be retracted by means of a hand wheel 37. If the supply of steam &c. fails, the clutch can be actuated, on moving the valve 29 in the appropriate direction, either by operating the pump 30 or by manually rotating a spindle 39 which is in threaded engagement with the rod 23. An additional hand oil pump 30<1>, which may be located on the deck of a ship in the case of a marine installation, has valve-controlled suction and delivery pipes connected to the two ends of the cylinder 28. Thus, on opening these valves, the clutch may be disengaged by operation of the pump 30<1>, a spring-opened valve 44 in the pipe connecting the exhaust side or the valve 29 to the pump 30 being closed by pressure communicated from the pump 30<1> through a pipe- 41. A cock 36<1> enables the locking pins 33 to be operated by the pressure from the pump 30<1>.

Title: Variable speed power transmission mechanism
IPC: F16H61/02
Filed: 1939-07-18
Abstract: 534,817. Variable-speed gearing. DAVEY, A. N. July 18, 1939, No. 20884. [Class 80 (ii)] In variable-speed gearing in which planetary movement of pinions is braked by means of drums fast to the pinions and having internal projections co-operating with a centrifugally maintained body of mercury or other liquid, the drums are formed with short teeth or serrations, a considerable number of which are submerged in the liquid and exercise a braking action by being forced therethrough, without, however, tending to carry liquid so far inwards as to impair the braking action ; mechanism interposed between the drums and a driven part provides for torque increase as well as infinitely variable speed-ratios. In the gearing shown in the Figure, a casing 3 on the driving-shaft 2 carries shafts 6 provided with pinions 8, and having internal teeth which co-operate in the above-described manner with a body 5 of mercury. The pinions engage a sun-wheel 9 on a sleeve 11 mounted on a shaft 12 which is connected by a one-way clutch 13 to the casing. Another sun-wheel 16 is splined to a disc 17 having clutch teeth 18 normally engaging the sleeve 11. The sun-wheel 16 engages pinions 10<1> which are mounted on a hollow shaft 14 and engage a pinion 26 on the shaft, and a floating annulus 23. At low speeds of the shaft 2, the energy is dissipated by the drums 4, and the sleeve 14 remains stationary. As the speed increases, the braking effect of the drums increases, the gears 11, 16 are retarded, the pinions 10<1> roll around the sunwheel 16, and the shaft 14 is driven with gradually increasing speed and torque, and then directly. For low gear, the annulus 23 is held by means of a brake 31 and the shaft 14 is driven through the shaft 12, and gears 26. 10'. As the speed of the shaft 2 is increased, the drums become stationary in relation to the casing, and the speed of the shaft 14 increases. On release of the brake 31, direct drive is gradually resumed. The clutch 13 may be provided with a centrifugal governor for preventing over-running of the shaft 12 when the brake is released. To provide for overdrive of a separate shaft, the shafts 12, 14 may be provided with a manually controlled over-running clutch. A higher overdrive can be obtained by holding the shaft 14 by means of a brake-drum 32. For reverse, the clutch-disc 17 is released from the sleeve 11, and held by means of a brake 36. drive being then transmitted through the gears 26, 10'. When change from reverse to forward drive is made, a one-way clutch 21 between the sleeve 11 and disc 17 speeds up the sun-wheel 9. The disc 17 is operated by a lever 33 and a rod 42 having a striker 41 for selectively engaging arms 38, 39 on rockers 37, 37a for operating the brakes 31, 36. The rod 42 may be operated by power.

Abstract: 243,814. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Sept. 5, 1924. Washing-machines with closed or enclosed rotary receptacles; supplying and discharging liquids and detergents to and from washing- machines.-Rotary washing-machines are electrically operated and are rendered entirely automatic in operation, so that by closing a starting switch button, the entire cycle of washing operations is commenced and automatically proceeds to a conclusion. The clothes receptacle is driven through gearing 5 from a reversible main motor 6. Three pilot motors also are provided, one of these, 22, being switched into and maintained for the proper period in circuit by a relay completed by closing the starting switch button 41. The pilot motor 22 closes the door 2 of the stationary casing 1 through gearing 18 .. 21 and also closes circuits or relays to switch the other pilot motors into circuit and maintain them in circuit for the proper period. One of the pilot motors 36, Fig. 3, thus switched in, continuously rotates, through reduction gearing 35, a controller drum 34 mounted on a panel 24 and carrying two sets of segments 37, 39 which coact with stationary contacts 38, 40, the series 37, 38 closing and opening circuits which include electromagnetically operated valves 10 in the hot and cold water supply passages 12, 13 and in the supply passages 9 from the containers 8 for the washing liquids and a similarly actuated discharge valve 15, whilst the series 39, 40 are included in the circuits of lamps 29 situated behind apertures 28 in the upper portion of the panel bearing legends corresponding to the phases of the washing-cycle, the particular lamp lighted giving an indication of the phase reached. The other pilot-motor, not shown, switched in by the closing of the casing door rotates another controller mounted on a panel 23 and carrying segments that coact with stationary contacts to vary the circuit through the main motor 6, so as continuously to reverse this motor, so that the clothes receptacle is rotarily oscillated thereby. The closing of the starting button also energizes one of a number of relays carried by a panel 25 to release a brake 37 on the shaft of the main motor. When the washing cycle is completed the various relays are opened, the brake is applied and the pilot motor 22 is operated to open the casing door. The timings of the various controllers are adjusted so that the clothes receptacle is stopped with its door, or one of its doors in the case of a multi-compartment receptacle, registering with the casing door.
