Abstract: 777,259. Pendant lamps. REVO ELECTRIC CO., Ltd. Oct. 17, 1955 [July 17, 1954], No. 20879/54. Classes 75(2) and 75(4) A pendant lamp incorporates a tension member, for instance a pair of channel strips 3, constituting means for adjusting a lampholder 7 and attached to an externally screwed tube 1, a circumferentially slotted plate 10 carried by the lower ends of the channel strips 3, a reflector 11 having a correspondingly slotted aperture engageable with the plate 10 with relative rotating action, a sleeve 8 surrounding the channel strips 3 and a screwed cap 9 on the screwed tube 1, the'arrangement permitting the reflector 11 to be releasably locked with the sleeve 8 in compression The channel strips 3 are dependent from diametrically disposed parts of an apertured plate 2 secured to the lower end of the tube 1. The lampholder 7 is connected to short channel strips 5 embraced by the channel strips 3 and having holes 5a held by split pins in alignment with pairs of holes 3a in the channel strips 3. Alternatively spring studs on the channel strips 5 co-operate with slots in the channel strips 3. The plate 10 supporting the reflector 11 has upturned lugs 10b preventing rotation of the reflector.

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M1/10
Filed: 1943-12-13
Abstract: 571,932. Spray carburetters. BENDIX AVIATION CORPORATION. Dec. 13, 1943, No. 20888. Convention date, Feb. 18. [Class 7 (iii)] A thermo-sensitive element acts as, or positions, a movable stop to determine the extent to which an unbalanced choke valve, urged to open by suction and to close by the thermosensitive device, can open of its own accord, when an independent manual control, which can move the valve throughout the whole range of movement thereof, is inoperative. A choke valve 22 provided with a poppet relief valve 26 is pivoted eccentrically about a shaft 24 which carries an arm 112 terminating in a lug 110 disposed between two stops 122, 124 on a Bowden wire 106 passing through the lug. When the wire 106 is pulled by a knob 101, the stop 122 engages the lug 110 and the valve 22 is completely closed, the other stop 124 engaging the lug when the wire is pushed to open the valve. As shown, the wire is locked in an intermediate position by a spring- pressed ball 116 engaging in a groove 114 in a plunger 100 connecting the wire 106 with the knob 101, the manual control is inoperative and the valve is actuated by suction tending to open it and a heat-responsive device urging it towards the closed position. The end of an arm 74 rigid with the shaft 24 is pivoted to a rod 98, the remote end of which slides in a socket in a sleeve 96 adjustably secured to a link 90 having its further end connected to a U-shaped heat-responsive element 76 disposed adjacent a hot spot 18. The sleeve 96 is adjusted to prevent the element 76, movement of which is limited by a stop screw 84, from closing the valve 22 completely, the rod 98 rising partly out of its socket in the sleeve 96. when the valve is wholly closed by pulling the knob 101. Opening the valve manually overrides the closing force of the element 76. The arm 74 is connected by a rod 72 with an idling cam 62 engaged by a stop 68 on the throttle valve control arm 40 to prevent complete closure of the throttle valve 36 and the cam may have a stepped portion 66 to provide for fast idling, a lost-motion connection 63, 65 permitting the throttle valve 36 to open slightly independently of the choke valve 22.

Title: Blindstitch sewing machines
IPC: G04B33/02
Filed: 1956-07-09
Abstract: 795,334. Sewing machines. SINGER MANUFACTURING CO. July 9, 1956 [Aug 2, 1955], No. 21147/56. Class 112 A blind-stitch sewing machine has a ridge-forming element fast on a rock-shaft 27 journalled on pintles 28 carried by a rock-frame 29 journalled on pintles 30 in a work-table 22 pivotally carried by a shaft 20 journalled in bearing lugs extending from the base of the machine. The rockshaft 27 is oscillated through a pitman 31 by an eccentric 33 on the driving shaft 34. A countershaft 52 driven at half or a third of the speed of the driving shaft carries an eccentric 56 operating a pitman 57 carrying a pivot pin 58 connected by links 59, 61 to the rock-frame 29 and a shaft 62 coupled by a lever arm 63 to a throw-out shaft 64 axially aligned with the pivot 58. In the position shown in full lines the machine will make one or two skip stitches followed by a single anchor stitch and so on. If the operating arm 68 on the throw-out shaft is moved to align the axis of shaft 62 with the axis of the pin 60 connecting the link 59 to the rock-frame 29 the pitman 57 idles and the machine makes anchor stitches only. Because the centre of the pivot pin is very close to the line AA joining the centres of the shaft 20 and the countershaft 52 the skip stitch mechanism is not noticeably affected by adjustment of the worktable by knob 47. Specification 774,070 is referred to.

Title: Method of and plant for steam generation

Filed: 1963-05-28
Abstract: 971,298. Arrangements of steam boilers. COMBUSTION ENGINEERING Inc. May 28, 1963 [June 19, 1962], No. 21269/63. Heading F4A. A method of supplying low purity steam to satsify the low purity steam requirements, e.g. for soot blowing, of a steam power plant, including a main steam generator, a turbine installation operated on a high purity steam cycle by said main steam generator, and an auxiliary steam generator operable during startup of said main steam generator to operate the auxiliaries thereof, comprises introducing low purity feed water into said auxiliary steam generator when the same is in a non-firing condition during normal operation of said main steam generator and turbine installation, extracting high purity steam from said high purity steam cycle, passing said high purity steam in heat exchange relation with said low purity feed water, thereby transforming said feed water into steam, and passing the socreated low purity steam to satisfy said low purity steam requirements. A main steam generator 10 comprises a combustion chamber 16, an evaporator 17, a superheater 18, a reheater 19 and burners 20, and an auxiliary steam generator 12 comprises a combustion chamber 33, a water drum 35 and a steam drum 34 joined by heat exchange tubes 36, and a superheater 37. During start-up of the main steam generator 10, burners 38 of the auxiliary steam generator 12 operate and high purity water from a source 40 is admitted to the auxiliary generator and turned to steam. With valve 45 open and valve 50 closed, the high purity steam passes through a superheater 37 and line 46 to operate the auxiliaries 13, e.g. turbine drives and feed water heaters, of the main steam generator before passing into a condenser 24 and into the main steam circuit. When the main steam generator 10 and the associated turbine installation 11 reach their normal operating condition, valve 45 closes and valve 31 opens, steam from the main circuit then driving the auxiliaries. Firing of the burners 38 ceases, and valve 42 is actuated so that low purity feed water from a source 41 passes into the auxiliary generator. A portion of the cold reheat steam exhausted from the high pressure stage 22 of the turbine installation 11 is passed through a heat exchange vessel 47 to the water drum 35 in which low purity steam is generated for soot blowing purposes in the main generator 10. This low purity steam is superheated in the exchange vessel 47. The remaining steam from the turbine installation 11 passes through a reheat section 19 to a low pressure stage 23 and the condenser 24. A three-element flow control system 43 controls the feed water flow to the generator 12 and the water level in the drum 34.

Class 59 In a roller mill for grinding liquid and pasty material having a grinding gate 5 and an auxiliary roller 3, the auxiliary roller rests freely on a main roller 2, is prevented from travelling around the main roller; and has associated therewith a feed unit 13, 14, 15 to supply material to be ground in the form of liquid strands of controllable thickness. The auxiliary roller bears against a wall 4 serving to guide the grinding gate 5 and forms with it and the main. roller a cavity 12 in which the material is homogenised before being discharged from the gate 5. The wall 4 is hollow and has cooling water supplied thereto. The gate 5 is adjustable, to vary the grinding gap, by means of screws 10 and is clamped against the wall 4 by means of bellcrank levers 7 and screws 8. The roller 3 is surrounded by a hopper-like container 16. The auxiliary roller can be movable up and down in a guide so as to be prevented from travelling round the main roller. Pasty material can be fed also by separate conveyer means to the main roller.
