Patent GB-721353-A (GB)
Title: Variable speed transmission
IPC: F16H61/02
Filed: 1950-08-01
Abstract: 721,353. Change-speed gear. COSTA, G., and BRERO, E. Aug. 1, 1950, No. 19190/50. Class 80 (2). An automatic direct overdrive planet unit, for installation between a main clutch and a manual direct-reduced gear (not shown) on a motorvehicle, comprises planets 11 carried by a clutchdriven input shaft 5, a ring-gear 12 carried by an aligned intermediate shaft 8, a one-way clutch 7 directly connecting the shafts for one-to-one forward drive, and a reaction sun 13, which is prevented by a one-way detent 15 from reverse rotation, and is also capable of being held for bi-directional overdrive by a fluid brake. The latter comprises a gear pump 50 driven by the reaction sun 13 and rendered effective by throttling under control of a centrifugal governor 20, which is driven through reducing gear by the intermediate shaft 8, and acts on a valve 57, which in the idle position shown, connects both input and delivery 52, 53 of the pump to an air space of a hydraulic fluid tank 56, and in the operative position (left) connects the input 52 to the fluid space and blanks the delivery 53 to brake the sun 13 for overdrive. Connected with lost-motion 33 to the governor-valve linkage is the usual clutch-pedal 31, depression of which, necessarily made during a shift in the manual unit, overcomes the governor and permits the valve 57 to return to the brake-release position, shown. An additional manual control may also be provided for the valve 57, and brake engagement is cushioned by a spring-loaded piston 61 in the brake-pump delivery line 53. Governor spring loading may be manually adjustable, Fig. 3 (not shown). The manual change-speed gear provides two ratios; 3 to 1 and 1 to 1, whilst the planetary gear provides 1 to 1 and 1 to 1.5. Shift sequence is as follows-On accelerating from start in first speed, overall direct-reduced 3 to 1, the governor 20 operates at an engine speed of 4,000 r.p.m. to upshift the planetary unit automatically, giving second speed, overall overdrive-reduced (2 to 1). Upshift to third is commenced in the manual unit, and the accompanying depression of the clutch-pedal 31 operates the valve 57 to downshift the planet unit, giving third speed overall direct-direct (1 to 1), which persists after release of the clutch-pedal 31 since the combined shifts have reduced the speed of the intermediate shaft 8 below governor cut-in speed. On further acceleration to governor cut-in speed, the planetgear again upshifts; giving fourth speed, overall overdrive-direct (1 to 1.5). Downshift occurs similarly, and to avoid loss of engine speed on an upgrade may also be induced in the planet unit by momentarily depressing the clutch-pedal.

Title: Improvements in and relating to crystal-controlled electric oscillation generators
IPC: H02M7/06
Filed: 1949-07-22
Abstract: 669,863. Valve generating circuits. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd., and FELIX, M. O. June 22, 1950 [July 22, 1949], No. 19401/49. Class 40 (vi). An oscillator comprises two valves having a piezo-electric crystal connected between the anode of the first and the grid of the second and a circuit tuned to a harmonic of the fundamental crystal frequency connected between the anodes, the whole circuit being arranged such that the negative feed-back through the capacitances between the anodes and the corresponding grids offsets the positive feedback between each anode and the grid of the other valve at all frequencies except the harmonics. It is explained that at the harmonic frequencies the effective crystal capacitances rises, providing a sufficiently increased positive feed-back to cause the circuit to oscillate. The grid circuits are aperiodic and as the grid resistors in the circuit shown are large the negative feed-back is provided by a potentiometer comprising the grid-anode inter-electrode capacitance, augmented if necessary, and the grid-cathode capacitance. The Specification also describes a known circuit, Fig. 1 (not shown), having a tuned circuit connected between the grids.

Filed: 1970-04-23
Abstract: 1280272 Electro-chemical analysis  CHLORINATION EQUIPMENT Ltd 30 Dec 1970 [23 April 1970] 19511/70 Heading G1N To determine the residual chlorine in effluent from a sterilizing plant the conductivity of the effluent is compared with that of the untreated water and the difference signal used to control the electrolytic generation of chlorine to provide equal residual in the untreated sample. The amplitude of the generater current to maintain equal conductivities, with a predetermined rate of fluid-flow, is a measure of the chlorine added in the sterilizing plant. As shown untreated water flows in line 1 and treated water in line 2. Both lines flow through a heat exchanger 5 to bring them to the same temperature and thence to respective cells 10, 11 and out at overflows 19. The electrodes are connected in a bridge circuit, Fig. 2 (not shown), to provide an output dependent on the difference in conductivities, and this signal is amplified to energize an electrolytic generator cell 24 providing chlorine on line 21 to mix with the untreated water. Hydrogen generated at electrode 23 is vented via line 26 and a liquid-level-balancing column 14. Modifications. The cells 10, 11 may be voltage generating instead of conductivity cells. The use of a reverse current possibly with a third electrode for electrolytic cleaning of electrodes is mentioned.

Title: Improvements in and relating to apparatus for indicating the energy of a blow
IPC: A61B5/22
Filed: 1928-07-06
Abstract: 320,373. Smith, G. July 6, 1928. Dynamometers for testing physical strength.- Apparatus of the kind in which a suspended punch ball is adapted, upon receiving a punch or kick or other blow, to rotate an indicator, is provided with selecting mechanism whereby a. prize or prizes' are delivered automatically when the indicator is rotated predetermined amounts. The apparatus is described as applied to a coin-freed apparatus. A coin in passing along the shoot 5 engages the lever 4 thus releasing the lever 2 and, through the detent o, the bar g connected at its upper end to the punch ball and at its lower end to a spring. The punch ball may now be lowered and upon striking the same rods 9 are raised carrying with them the piston 12 and compressing the air in the cylinder 13. The movement of the diaphragm 14 acting through the rod 17 rotates the wheel 22 and the indicator against the action of the spring 27. The wheel 22 carries a drum having apertures in its periphery which coact with a projection 52 on one or more pivotally supported rods 36 connected at their lower end to slides 38, 39, 40. Each slide has a hole 42 which is directly below the magazine 6 when the slides are in their innermost position and receive the lowermost coins from the magazine. Springs 45 urge the slides outward and each of the lower slides has an upstanding part that engages the next upper slide whereby all the slides are returned when the lever 47, struck by the pin y on the rod g in its upward movement, engages the lowest slide. The lever 47 holds the slides in this position, until the rod g is retracted by the engagement of the catch 48 on the lever 49 with the pin 51. The upward movement of the rod resets the lever 2 and when the rods.9 are forced upwards' by the blow, the rod 61 moves a pawl s and releases the rod g. The wheel 22 is retained in its extreme position by the pawl 54 and according to its position determines the action of the rods 36 on the selector slides'. If the slides are operated, prizes pass down the shoot 43 to the outside of the machine. When the machine is again operated the upward movement of the rod 9 raises the pawl 54 and releases the wheel 22 and the indicator.

Filed: 1966-05-04
Abstract: 1,127,498. Feedwater heating systems. CENTRAL ELECTRICITY GENERATING BOARD. 27 April, 1967 [4 May, 1966], No. 19782/66. Heading F4A. [Also in Division H2] An MHD steam cycle system is combined with a further steam cycle system having an independent source of high grade heat and utilizing for feed water heating the low grade heat from the MHD steam cycle system. The MHD steam cycle system comprises an MHD plant 10 and a steam turbine plant 24 in which the steam is raised by a heat exchanger 25 downstream of the MHD duct 15. The combustion chamber 11 is fed with fuel at 12 and with heated combustion air at 13. A further steam turbine plant 40 has its boiler 43 and superheater 44 heated by an independent source of heat, either a fossil fuel or a nuclear energy fuel. Its feed water is heated, between the condenser 48 and the feed water pump 42 by passing it through cooling ducts 20 surrounding the combustion chamber 11 and MHD duct 15 (and, it may be, the magnet system) and through a low temperature economizer 35 downstream of the MHD duct. This means of heating the feed water eliminates the usual high temperature economizer and, it may be, some or all of the regenerative feed water heaters. This arrangement reduces the efficiency of the plant 40 but increases the efficiency of the plant 10, 24; the overall efficiency of the combination 10, 24, 40 is increased. The feed water for the plant 24 may also be heated in this manner, the regenerative heaters 29, 30, 31 then being eliminated. A separately fired air preheater may be used for the plant 10, 24 and the heating gases of this preheater may be used in the plant 40. The exhaust gases from the MHD duct may be used for preheating the combustion air for the plant 40 or the plant 24 or may operate a high temperature economizer for the plant 24.
