Patent GB-2027099-A (GB)
Title: Sheet Metal Lintels
IPC: E04C3/02
Filed: 1978-07-29
Abstract: A metal lintel comprises a box section having a base plate, upright front and back plates and a generally horizontal profiled metal top plate provided with one or more stiffening ribs extending throughout substantially its entire length. The box section supports a wall of standard bricks and has a height approximately equal to one standard brick and, optionally, a width approximately equal to one standard brick. The lintel may also include a forwardly projecting extension of the base plate, adapted to support an outer leaf of a cavity wall, and an inclined damp resisting member. By incorporating a heavily profiled ribbed top plate, the stiffness of the lintel is greatly improved compared with a lintel having a flat top plate, so that adequate stiffness and rigidity can be obtained in a lintel having a box section equal only to the size of one standard brick, with consequent saving of weight and of material used in construction of the lintel. <IMAGE>

Title: Synthesis of deoxyvincaminic acid amides
IPC: C07D471/20
Filed: 1978-10-24
Abstract: Process for the production of the deoxyvincaminic acid amides corresponding to the formula   <IMAGE> in which either R' and R'' each represent, independently of one another, a hydrogen atom, an alkyl radical , a phenylalkyl radical, a cycloalkyl radical or a cycloalkyl-alkyl radical, the alkyls having from 1 to 4 carbon atoms, or R' and R'' form, together with the nitrogen atom, a heterocyclic radical which can contain from 4 to 6 carbon atoms and/or another hetero-atom, O, S, or N, and can carry a hydrogen atom or an alkyl on the other nitrogen atom, in which process tabersonine, in the form of the racemate or an optical isomer, is hydrolysed into tabersoninic acid (II), this acid is converted into a reactive derivative (III) in order to obtain the amide (IV) by a conventional method, and then either this amide (IV) is subjected to an oxidative rearrangement which leads to compounds (V) and (VI) and, after having dehydrated compound (VI) into compound (V), this compound (V) is converted into deoxyvincaminic acid amide by hydrogenation in accordance with the following reaction scheme, or the amide is directly subjected to an oxidative rearrangement which leads to the N-oxides of compounds (V) and (VI) and, after having dehydrated the N- oxide of compound (VI) into the N-oxide of compound (V), the latter is converted into the N-oxide of deoxyvincaminic acid amide by hydrogenation and, finally, the N-oxide group is removed by reaction with triphenylphosphine. These compounds are useful in treating cerebrovascular disorders. Tabersoninic acid derivatives are claimed as intermediates for use in this process.

Title: Method and apparatus for automatically controlling arc welding
IPC: B23K9/127
Filed: 1979-01-23
Abstract: A method and apparatus for automatically controlling arc welding wherein pieces of optical information provided by at least two bands of different wavelengths of light, radiated from a weld area being arc-welded under predetermined-welding conditions, are alternately picked up by an optical device, e.g. TV camera 11, to extract various weld factors representing the actual status of the weld area from these pieces of optical information. The extracted weld factors are compared with the desired values of the weld factors representing the desired status of the weld area to compute in unit 20 the error or errors of the welding conditions, so that the welding conditions can be corrected on the basis of the detected error or errors of the welding conditions, whereby the weld factors can be controlled to the desired values. <IMAGE>

Patent GB-790724-A (GB)
IPC: F16K31/68
Abstract: 790,724. Valves. ROBERTSHAW-FULTON CONTROLS CO. Jan. 25, 1956 [May 19, 1955], No. 2478/56. Class 135. The interior of a bellows 50 is connected to a temperature-sensing device as well as a reservoir bellows 86 by capillary tubing, all of which are filled with a volatile liquid; the sensing device comprises a bulb and bellows which latter is manually adjustable to vary the volume of volatile liquid in a surrounding space. When the closure 24 is unseated steam passing between the valve inlet 12 and outlet 14 contacts the bellows 50, which is attached to the closure 24, and thereby vaporizes the liquid therein as well as the liquid in a bore 56 connected to the interior of the bellows 50 by passages 42 in a disc 40 slidable in the bore 56. A pressure P1, which is thereby generated in the bellows 50, is insufficient to overcome the bellows spring 46 and move the bellows 50; this pressure also acts upwardly on a power bellows 58 in the bore 56, and downwardly in reservoir bellows 86, joined to the power bellows 58 by a stem 62, so that there is a resultant upward force directly proportional to the difference in areas between the bellows 56 and 86, which force is counterbalanced by the spring rate of the bellows and an adjustable spring 126 acting on a lever 112 attached to the stem 62 so that the system is balanced with the closure 24 and bellows 52 fully open. When the temperature of the sensing device increases, additional liquid is forced thereby into the bellows 50 wherein it vaporizes and causes the production of a higher pressure P2 which acts on the area difference between the power and reservoir bellows 58 and 86, thereby destroying the system balance and causing upward movement of the power bellows 58, and hence the reservoir bellows 86, which results in some of the liquid from the latter being forced, via capillary tubing, into the bellows 50 so producing a further pressure increase therein, this regenerative action continuing until the upward Quid force is again balanced by the force produced by the continued expansion of the spring 126 and the spring rate of the bellows. The closure 24 will be seated when the sensing bulb attains the required temperature. Should the bulb temperature fall condensation of the vapour occurs and so the pressure inside the bellows 50 is progressively lowered and the spring 126 forces the bellows 58 and 86 to move downwardly until the system is again balanced, whereupon the closure 24 is opened the requisite amount. The force exerted by the spring 126 may be adjusted by either varying the fulcrum point of a lever 112 on a support 114, the anchor positions of either end of the spring or the position of the pivots 109 on the stem 62.

Title: Shuttlecocks
IPC: A63B67/18
Filed: 1979-08-17
Abstract: A shuttlecock comprises a cap portion 1 and a plastics skirt 3 in the form of a truncated conical lattice structure having main stems 5 interconnected by ribs 11 with further intermediate stems 9 located between the main stems, the lattice structure in the vicinity of the wide end of the skirt being convoluted with the flutings 23 extending at an acute angle, preferably 45 DEG  to the longitudinal axis of the shuttlecock, and being so orientated as to make the shuttlecock spin and otherwise behave as a feathered shuttlecock. Preferably, slots or slits 17 are provided in the skirt at its wide end and the convolutions extend approximately from one end of one slot to the opposite end of an adjacent slot.

Title: Stabilised high intensity discharge lamp
IPC: H01J61/28
Filed: 1979-11-21
Abstract: An amalgam is disposed within the arc tube of a high intensity arc discharge lamp so as to stabilize the electrical power being supplied to the lamp against variations in line voltage.
