Title: Improvements in domestic hot-water boilers
IPC: F24H9/20
Filed: 1949-04-01
Abstract: 675,286. Interconnected valves. FORD, T. April 1, 1949, No. 8881/49. Class 135 [Also in Group XIII] A gas-fired, self-feeding, hot-water boiler having a water draw-off tap at its upper end, and a gas tap at its lower end, is provided with a disengageable coupling 9 linking a pair of vertically disposed axially aligned connecting rods 7, 8 each rotatable on operation of either of the taps, the arrangement being such that by manual operation of the coupling, one rod may be disconnected from the other, the rods being automatically re-coupled when either the water tap is opened or the gas tap is closed. Preferably, the coupling is slidable on both rods whilst being in constant driving connection with the one rod, e.g. (the rod 7) and in disengageable connection with the other rod, the rods being uncoupled by an axial and then a turning motion of the coupling. As shown, the coupling body member 10 is slotted at its upper end slidably to accommodate a pin 14 extending through the lower end of the rod 7, and is fitted at its lower end with a pin 16 slidable in a slot 15 at the upper end of the rod 8. In Fig. 2 the rods 7, 8 are shown coupled together and when it is desired to disconnect them, e.g. on starting the boiler, the coupling is gripped with the hand, raised and then given a half-turn so that the pin 16 is disengaged from the slot 15 and rests on the top of the rod 8, Fig. 3, thus disconnecting the gas and water taps from each other. When the water in the boiler has reached the desired temperature, operation of either the gas or water taps re-engages the coupling.

Abstract: 1,188,495. Planetary change-speed gear. FORD MOTORO CO. Ltd. 19. Feb., 1969 [11 April, 1968], No. 8905/69. Heading F2D. Comprises an arrangement of one- and twoway clutches and brakes for compounded, series and single working of two simple sun-ring-planet trains 14, 16 giving, in Fig. 1, three reduced ratios, direct-drive and one or two reverse ratios; and in Fig. 3, not shown, two reduced forward and two reduced reverse ratios, both embodiments using the same train arrangement, but the latter dispensing with some of the clutches. Shifts are by pick-up from overrunning couplings. The gear is used on a motor vehicle and is driven through an hydrodynamic torque-converter. The sun 20 of the first train 14 is permanently connected to input 10, the carrier 30 of the second to output 12, and the carrier 22 of the first to the ring 26 of the second. Ratios are as follows. First-trains in series both reducing. The ring 18 of the first train reacts through a sleeve 44, one-way coupling 46 and one applied friction brake 42; the first carrier 22 drives the second ring 26, whilst the second sun 28 reacts through the same brake 42 to provide second-carrier output. Second-accelerated compound. The brake 42 remains on to react the second sun 28, as before, but now a clutch 48 is also engaged to feed back a forward reduced drive from the output 12 through the second carrier 30, one-way coupling 51, clutch 48 and sleeve 44, to the first ring 18, thus accelerating the latter with pick-up action from the now overrunning one-way coupling 46. Third-second train alone. The first train 14 is locked up by engaging a friction clutch 34, thus accelerating the ring 26 of the second train 16 which drives alone in reduction, the brake 42 and clutch 48 remaining on, and one-way couplings 46, 51 being overrun by the pick-up. Fourth-direct-drive. Additional engagement of a friction clutch 58 locks the second sun 28 to the first ring 18 for two-way direct-drive. Two-way first and second are provided by engaging respectively clutches 58 and 50. First reverse-series trains. A brake 36 is applied to hold the connected first carrier 22 and second ring 26. This reverses the first ring 18, which drives the second sun 28 through the one-way coupling 46, the second train reducing. No other clutch or brake is applied. Second reverse-first train alone. The clutch 50 is engaged to eliminate the second train 16 and permit the reversed first ring gear 18 to drive direct to output 12 through the clutch 50 and second carrier 30. Fig. 3, not shown, uses only the first two forward ratios and the two reverse ratios, the clutches 34, 48 and one-way coupling 51 being eliminated.

[Classes 39 (i) and 40 (iii)] The middle plate of a 3-plate deflecting system of the Braun-tube, television arrangement described in the parent Specification is divided into two separate parts 5, 6 spaced for the passage of the ray 2. The parts 5, 6 may be at the same or different bias potentials, the ray leaving the deflecting system parallel to its direction of entry, or striking the centre of the screen, when no scanning voltages are applied. As shown, the parts 5, 6 are connected by a high resistance 7 arranged in the tube itself and are positively biassed relatively to the anode 1 and to the outer plates 3, 4, and scanning potentials of opposed phase are applied to the plate 4 and the part 6. Scanning voltages are amplified by a pentode 9 before application through a condenser 10 to the plate 4 and are reversed in phase by a pentode 13 before application through a condenser 14 to the part 6. The tapping point on the anode resistance 11 is adjusted so that the voltages on the plates 4, 6 are of equal amplitude and the pentodes are fed through a potentiometer 17 so that smoothing in the anode supply to the pentodes can be reduced or dispensed with. A system of this type is used for both line and image deflections and the transmitter is modulated more heavily for the line frequency since the image frequency permits of better amplification. Circuit details are specified. Specification 423,427 is referred to.

Abstract: 266,557. Kruckenberg, F., and Stedefeld, C. April 9, 1926. Energy - absorbing elements; acting on flat sides of wheels; skid.-In a braking airangement for cars of true streamline form, as shown in Figs. 1 and 2, for high-speed suspension railways, for braking the cars at high speed air brakes are provided for increasing the air resistance and producing energy-absorbing turbulence in the slip stream and the air screw 10 is reversible, while for braking at low speeds, friction brakes acting on the running wheels and rail brakes, serving also as emergency brakes, are provided. In one form, the air brakes comprise hinged plates 1, 2, Fig. 2, curved externally to conform with the streamline shape of the car and adapted to be turned outwards by levers, handwheels, &c. to uncover hollow spaces with curved inner walls 3. 4. Air intercepted by the opened plates 1, 2 is directed inwards and meets the walls 3, 4 by which it is directed outwards behind the plates across the already turbulent air streams which are therebv widened. In another form, channels 5, 6, Fig. 3, in the nose of the car have sliding cover plates 7, 7<1>, 8, 8<1> which may be opened allowing air streams to enter the channels from which they are ejected sideways across the slip stream, thus producing turbulence. Vanes 9 are provided at the channel exits. The reversal of the air screw may be effected by using a screw of reversible pitch, by the use of a reversible motor, or, as shown in Fig. 1. by the use of a reversing gear 13 a clutch 11 on the shaft of the motor 14 being first disengaged. the screw shaft then braked by a brake 12. and the gear 13 reversed, so that when the clutch 11 is re-engaged. the screw 10 is driven backwards. When the effectiveness of the air brakes has diminished with decrease in speed of the car, friction brakes 15 acting axially upon the sides of the running wheels are brought into action, their effectiveness being increased by the provision of counter wheels drawn upwards against the rail 19 by springs which come into action during braking. The rail brakes comprise shoes 17, 18 guided laterally in frames and pressed against the rail 19 by suitable mechanism. Specification 27549/96, [Class 103, Railway &c. vehicles], is referred to.
