Title: Improvements in or relating to electro-magnetic induction apparatus having a laminated iron core
IPC: H01F27/33
Filed: 1950-10-27
Abstract: 687,743. Inductances. GENERAL ELEC. TRIC CO., Ltd., and PARK, K. J. Oct. 29, 1951 [Oct. 27, 1950], No. 26307 /50. Class 38 (ii). Electro-magnetic induction apparatus comprises a laminated iron core made up of two E-shaped parts 10, 11 which butt together at their outer limbs with an air gap 12 between the central limbs, a coil 13 being mounted on the composite central limb so as to surround the air gap, the two parts of the core being secured together and the laminations held against vibration by welds 14 at the outside of the outer limbs where they butt together. Increase in the external dimensions of the apparatus may be avoided by placing the welds in grooves formed in the core parts.

Title: Method of ageing whiskey
IPC: C12H1/00
Filed: 1934-09-14
Abstract: Charcoal for improving the colour and flavour of whisky is produced by heating white oak in an externally heated muffle furnace to about 700 DEG  C. for one or two minutes.  The charcoal is regarded as divided into three layers, of which the inner two only contain appreciable amounts of alcohol soluble constituents and are utilized for treating the whisky.ALSO:Whisky is aged by catalytic hydrogenation, the liquor being subjected to an atmosphere of hydrogen or treated by bubbling hydrogen therethrough in the presence of platinum, nickel, chromium, iron, copper oxide, or other hydrogenation catalyst until the undesired odours are removed. Platinum black and nickel reduced in hydrogen at 300 DEG  C. are the preferred catalysts. The treatment may be carried out at super-atmospheric pressure, especially in the case where a nickel catalyst is used, and the liquor may be agitated during the process. The deodorized whisky is preferably subjected to a subsequent treatment with charcoal obtained by heating white oak in an externally heated muffle furnace at about 700 DEG  C., for one or two minutes.  The outermost charcoal layer thus formed is not employed, the liquor being heated at 60 DEG  C. with a mixture of the two inner layers into which the remainder of the charcoal is regarded as divided, and which contain alcohol soluble constituents.

Title: Improvements in or relating to computed price and/or delivered quantity register control mechanism for liquid dispensing apparatus
IPC: B67D7/08
Filed: 1957-08-21
Abstract: 829,717. Petrol pumps. TOKHEIM (INTERNATIONAL) A. G. Aug. 21, 1957 [Aug. 27, 1956], No. 26424/57. Class 116 A petrol dispenser is provided with a single hand lever 175 which when moved anticlockwise first allows the quantity and computed price registers 5, 7 to be reset by gearing 15, 17, 19 and a spring 73 and then closes the pump motor switch 6 (Fig. 6). The lever is then moved by a spring in the return direction far enough to obstruct the nozzle support 173. Further manual return movement of the lever opens the motor switch, conditions the resetting mechanism for a subsequent resetting operation and clears the nozzle support 173 to receive the nozzle. The lever 175 rotates a plate 195 connected through arcuate slots 199, 201 and links 203, 205 with levers 183, 105, and a spring-loaded pawl 209 which is pivoted on the plate resists relative movement between the end of link 205 and slot 201. Initial movement of the plate rotates lever 178 only and this movement is transmitted through shaft 181 and hub 105 to move a pawl 103 (Fig. 2) clockwise so tripping a pawl 59 and allowing spring 73 to reset the registers. Further rotation of the lever 175 overcomes pawl 209 and rotates the plate to take up the lost motion in slot 199 whereafter lever 183 is moved clockwise causing projection 185 to depress plunger 187 of switch 6 and simultaneously, through shaft 179, hub 33 (Fig. 2) ratchet disc 31 and shaft 23, clutches the registers to the meter (not shown), and declutches them from the reset mechanism. When the lever 175 is released by the operator it is returned by a spring to an intermediate position in which it obstructs the nozzle support 173 and during this movement lever 183 is partly returned by spring 188 to a position in which pawl 59 is engaged by a tooth 41 on wheel 31. Switch 6 meanwhile remains closed. At the conclusion of the dispensing operation the lever 175 is returned to its original position so further rotating lever 183 which causes hub 33 to rotate and cock spring 73, switch 6 to open, and the nozzle support 173 to be cleared. Specification 753,542 is referred to.

Title: Improvements in or relating to the machining of impeller wheels

IPC: B23C3/18
Filed: 1951-11-12
Abstract: 707,256. Copy-milling. THOMPSON PRODUCTS, Inc. Nov. 12, 1951, No. 26427/51. Class 83 (3) A method of milling the space between the adjacent vanes of an impeller wheel W consists in oscillating the work so that the cutter T traverses the whole width of the recess while the cutter and work are moved relatively to generate the required profile of the recess. A machine for carrying out the method comprises a milling tool T rotated by a motor 34 and mounted on a vertically movable slide 15, a cross slide 14 on a pedestal 11, and a motor 20 for rotating a screw 22 for feeding a work-carriage 12 carrying the impeller blank W. As the carriage 12 is fed, the work W is rotated by a cam follower 23a, a rack-bar 23 and a gear 24 on the work-spindle: The follower is held in contact with a cam B, and back-lash is taken up, by a hydraulic force applied to a rack-bar 26. For obtaining greater accuracy, the cam B is elongated and is traversed over a longer path than the slide 12 by a screw 21. The motor 20 also moves the cutter-slide 15 through shafts 28, 29 and a cam A, and traverses the slide 14 through a cam C and a follower 31a which are held in contact by a hydraulic piston 32b. The machine thus far described is similar to that described in Specification 655,207. The oscillation of the work to generate the root surface between adjacent vanes is imparted by a motor 83 through an adjustable crank 85, a lever 80 pivoted to a member 76 carrying a slideblock 78, a bell-crank 79, 71 and a slide-block 75 engaging a plate 54 to which the work is secured. The pivot 73 of the bell-crank 79, 81 is journalled in a ring member 52 secured to the spindle 13. Thus, as the impeller is moved angularly, the degree of oscillation becomes less. The work is indexed by a peg 62 which is inserted in an appropriate recess, 59a in a plate 59 fast with the plate 54.

Title: Synthesis of esters
IPC: C07C51/12
