Abstract: 1277012 Ignition burners RADIATION Ltd 29 May 1969 [1 March 1968] 51585/71 Divided out of 1277011 Headings F4F and F4T An ignition burner 33 or 55 is threadably secured to a main burner via threaded adaptor 32 and acts to ignite the gas burner: the ignition burner comprises a gas bore 38 or 57 which communicates with a main ignition orifice 39 (or 59) and a slit orifice 41 (or 56) which merges with a further orifice 43 (or 61). In the embodiment of Figure 4 a ring of orifices 40 are provided around the main orifice 39. In operation gas/air mixture from the main burner passes through a bore 37 of the adaptor 32, into the bore 38 and emerges from the orifice 39 whence it passes along a flash tube (not shown): the mixture is ignited by a pilot flame and a flame travels back along the flash tube to the orifice 39 and spreads also to the orifices 40 to form a ring of retention flames around the orifice 39. The flame also spreads to orifices 41 and 43 and the flame from orifice 43 ignites the main burner. In the embodiment of Fig. 6 the slit orifice 56 merges with the main orifice 59 and acts to provide a retention flame, no orifices 40 being provided. The ignition burners and the adaptor are made of brass, and they may be used with main burners as described in Specification 1,277,011.

Filed: 1970-10-30
Abstract: 1335194 Hydraulic reciprocating pumps and motors MACHINEFABRIEK STORK-JAFFA NV 30 Oct 1970 [30 Oct 1969] 51817/70 Heading F1A [Also in Division B5] A pump or motor comprises a plurality of axial cylinders 8 with opposed pistons 9, 10 reciprocated by rotary swash-plates 5, 6, each cylinder 8 having a distributing slide valve 17, Fig. 4, movable from its neutral position shown to right or left to connect its associated cylinder 8 to either of high and low pressure connections 23, 26, and the movement of each valve being controlled by mechanism responsive to electrical pulses received from the exterior to cause the respective cylinders to function in pumping or motoring modes. The electrical control pulse is supplied to a relay 57, which also receives control signals from a proximity switch 55 responsive to apertures 54 in a disc 53 rotating with the drive shaft, so that the relay only feeds the control pulse to the valve actuating mechanism when the corresponding pair of pistons are in their top or bottom dead centre positions. The valve-actuating mechanism comprises a rod 18, 27 connected to valve 17 and pivoted at 28 on a lever 29, which is pivoted at 30 to the armature 32 of an electromagnet; and at 45 a swash-plate 47 rotated by the drive shaft through gearing 50 to 52, so as to rotate at twice the speed of the drive shaft. Lever 29 is also pivoted at 38 on a lever 35 which is pivoted at its upper end on the pump or motor housing 1 and biased by spring 41 against a stop 43. If an electrical control pulse is received at relay 57, electromagnet 33 is energized when pistons 9, 10 are at a dead centre position, and armature 32 is held stationary, so that swash-plate 47 causes lever 29 to pivot with lever 35 about axis 30 against spring 41 to move rod 18, 27 and valve 17 to the left. If no control pulse is received, armature 32 is free to move, and swash-plate 47 causes lever 29 to pivot about axis 38, lever 35 being held against stop 43 by spring 41, to move valve 17 to the right. The pump or motor may be used to operate a hydraulic press (see Division B5).

Title: Timer
IPC: G04C23/18
Filed: 1968-11-01
Abstract: 1,216,279. Timing devices. UNION TANK CAR CO. Nov.1, 1968 [Nov.1, 1967], No.51818. Heading G3T. A timing device for actuating a mechanism, such as the valves in a water softening system, at a predetermined time comprises a motor 25 adapted to rotate a timer dial (130), Fig.3 (not shown) and a pinion 35, a gear assembly 50 operatively connected to the mechanizm and including a ring gear 57 having a cut away portion 59, an arm 90 for initially rotating the ring gear to cause the ring gear to mesh with the pinion and pins 85 on the timer dial for causing the arm to initially rotate the ring gear. Two gear systems (not shown) in a gear box 20 transmit a drive from the output pinion 26 of the synchronous electric motor 25 to a shaft 30 to rotate the timer dial at one revolution per week and to the pinion 35 to rotate this pinion at one revolution per fifteen minutes. A locking cap 78 is screwed on to the threaded end 77 of the shaft 30 and secures a disc 74, attached to the dial, to the shaft. The ring gear 57 is mounted on a shaft 51 connected to a shaft 11 on which are positioned cams for operating the valves. To set the timing device to cause actuation of the valves at a particular time on a particular day, the appropriate one of the seven pins 85 corresponding to each day of the week is pressed inwardly and the dial (130) is rotated until the selected time on the dial plate, which is marked with fourteen sets of 3, 6, 9 and 12 hour indications, is aligned with the centre of the selected pin. The cap 78 is then loosened and the disc 74 rotated with the dial (130), which has been tightened onto the disc, until the existing  time coincides with an arrow 139 on the face plate 140. After tightening the cap, the disc 74 is rotated by the motor until the pre-selected time is reached whereupon the depressed pin engages a finger 101 of the arm 90, which is mounted on a plate 31 and biased by a spring 98, to push the arm sideways. An abutment 103 on the arm engages an abutment 105 on a flange 60 of the ring gear to rotate the ring gear so that the pinion 35 meshes with teeth 110 of a tooth arm 111. The  arm 111 transfers the pinion into mesh with teeth 58 of the ring gear which is thus rotated to actuate the valves for a period of time until the ring  gear has been rotated to such a position that the cut away portion 59 is adjacent the pinion.
