Title: Improvements in grates
Inventor: HOULT FREDERICK HERBERT
IPC: F24B13/02
Filed: 1953-07-09
Abstract: 737,952. Fireplaces. NEWTON, CHAMBERS & CO., Ltd. July 29, 1954 [July 9, 1953], No. 19123/53. Class 126. A substantial part of a domestic firegrate consists of curved bars with a common centre of curvature at or close to the front of the grate and a raking arm is pivotally mounted to swing about this centre just below the bars, this arm having a series of fingers which project upwards into the curved slots therebetween. The grate shown comprises curved bars 1, radial bars 4 and straight bars 5 and this grate is supported in a fireplace by lugs 12, 13 cast integrally with, and on the inside of, side walls 8 of a casting which forms the ashpit front 7. The front edge 3 of the grate abuts lugs 27 formed on the rear edge of a bar 10 which lies parallel with the front 7 and is secured thereto. Rearward displacement of the grate is prevented by the interengagement of a dovetail projection 26 on the edge 3 entering a corresponding socket in the bar 10. A raking arm 14 with upwardly extending fingers 15, 16 is disposed beneath the grate, as shown a head part 18 formed with the arm and provided with a hole 19 being located beneath the centre portion of the bar 10 such that a pivot pin 2 may be passed therethrough into the hole 19. Horizontal parts 17 of fingers 16 hold the arm in engagement with the bars 1 and the arm is oscillated about the pin 2 by a special tool 21. This operation is performed by inserting the tool through the ashpit opening until a waist portion 24 lies beneath a dovetail slot 20 in the arm head 18. The tool is then raised and drawn forward, causing a correspondingly shaped portion 23 to interengage the slot 20 and a forked end 22 to abut the inner surface of the head 18. The tool 21 is then rigid with the arm. The bar 10 supports a firebrick lining the upper inner surface of the front 7.

Title: Improvements in or relating to electrical impulse generators
IPC: H03K4/16
Filed: 1935-07-05
Abstract: 459,302. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and BANKS, G. B., Highfields, First Avenue, Chelmsford. July 5, 1935, No. 19309. [Class 40 (v)] A saw-tooth-voltage generator comprises a condenser 3 from which the voltage is derived and which is continuously charged through a resistance 4 (preferably a saturated diode or a tetrode) and is shunted by the anode-cathode path of a back-coupled tetrode valve to the screen of which the synchronizing impulses are applied. A bias battery ensures that the valve is normally nonconducting, but when the condenser voltage reaches a sufficiently high value, or a synchronizing impulse is received and current does flow in the anode circuit, the back-coupling ensures that it will increase and so discharge the condenser rapidly.
Patent GB-911049-A (GB)
Title: Variable ratio gear transmission
Inventor: EVERNDEN HAROLD IVAN FREDERICK
IPC: F16H47/08
Filed: 1959-06-05
Abstract: 911,049. Hydro-mechanical variable-speed gear. ROLLS-ROYCE Ltd. May 27, 1960 [June 5, 1959], No. 19371/59. Class 80 (2). A planetary change-speed gear for a motor vehicle which provides two reduced ratios, direct drive, overdrive and one or two reverse ratios comprises two series trains 16, 35 with a fluid coupling or, as shown, hydrodynamic torque converter 13 therebetween, the former train 16 driving the impeller I of the torque converter at direct or overdrives speeds. As shown, there are two control clutches A, D and three control brakes B, C, E and torque-splitting occurs in direct and overdrive ratios, the others being all fluid drive. First ratio (directreduced) is obtained by engaging the clutch A and brake C. The clutch A locks the front train for direct drive by connecting its planet carrier 15, which is fast with an input shaft 10, to its reaction sun gear 18. An output ring gear 19 of the front train 16 is fast with the impeller I of the torque converter, the turbine T of which is fast on an intermediate shaft 33 which carries at its rear end a first input sun gear 34 of the rear train 35, planets 39 of which are carried by the final output shaft 47. The brake C is applied to a drum 45 fast with a reaction sun 43 of the rear train which thus reduces. For second ratio (overdrive-reduced) the brake C remains engaged, so that the rear train is unaffected, the clutch A is disengaged and the brake B engaged to hold the front reaction sun 18 and upshift the front train 16 to overdrive. For third ratio (direct-direct) the clutches A and D alone are engaged, the former clutch A locks up the front train to drive the first sun 34 through the torque converter whilst the latter clutch D connects the input 10 to a shaft 43 to drive a second sun 54 of the rear train at the same speed, thus providing a split-torque direct drive. Fourth ratio is obtained by engaging clutch D and brake B the latter upshifting the front train to overdrive, the rear gear acting as a differential to recombine the torques of the overdriven first sun 34 and directly driven second sun 54. For reverse (direct-reverse) the clutch A and brake E are engaged, the former locks up the front train 16, whilst the latter holds a reaction ring gear 42 of the rear train which thus reverses. A second reverse ratio (overdrive-reverse) may be provided by engaging the brakes B and E which upshifts the front train 16 whilst leaving the rear train unaffected. In Figs. 5-7 (not shown), the clutch D, shaft 49, sun 54 and planet pinion 40 of Fig. 1 are omitted and a clutch is inserted between the reaction sun and planet carrier of the rear train which clutch is engaged to lock up the rear train for direct drive and overdrive ratios, the other ratios are provided as above described. The control clutches and brakes are hydraulically operated by manual or automatic means (not described).
