Abstract: 941,362. Automatic control of current density. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 13, 1961 [April 19, 1960], No.13639/60. Heading G3R. The current density in an electroplating bath is maintained constant by a regulator responsive to the potential between an electrode in the bath and a reference probe electrode. As shown, a bath 1 having a working anode 2 and a working cathode 3 is supplied with plating current over a variable resistance unit 6. The potential at a reference probe 7 positioned adjacent the cathode 3 is compared, by means of a vibrating-type relay having contacts 9, 10 and armature 15, with a reference voltage set on a potentiometer 13, and any resulting error signal is applied over an A.C. amplifier 16, a further relay 16,17,18, and a D.C. amplifier 22 to the base of a transistor in the unit 6 whereby the emitter/collector current of the transistor, i.e. the plating current, is varied in a sense to bring the voltage at contact 9 to the same voltage as is present on contact 10. The current density is thus maintained at a desired value selected by adjusting the potentiometer 13. The probe electrode may be located adjacent the anode 1 instead of the cathode 3, or it may be arranged adjacent an auxiliary electrode connected to the working anode or cathode.

Filed: 1951-06-11
Abstract: 727,970. Casting buildings on inflatable cores. KERMAN, E. June 11, 1951, No. 13744/51. Class 20 (2). In casting a building on an inflatable core which is deflated for withdrawal after setting of the concrete, the core comprises a flexible skin with its opposite lateral edges maintained at ground level and at least one fluid-tight envelope covered by, or in part constituting, the central portion of the flexible skin, which envelope is inflated so as to hold, or to co-operate with internal supporting means in holding, the general plane of the lateral portions of the skin substantially flat and either vertical or inclined but without the ground being subjected to any inflation pressure. In one form, Figs. 1, 2, the envelope 1 on inflation assumes a cylindrical form with hemispherical ends and skirt members 2 secured to the envelope are reinforced by braces 3 and have their free edges secured to the foundations 6. Wire netting 8 is laid over the core and frames 9 for doors and windows are secured to the netting 8 and the concrete coating 7 then applied. Instead of the attached skirt members 2, a separate sheet may be laid over the inflated envelope and secured on opposite sides to the foundation. In another form, Fig. 5, the core comprises an assembly of small envelopes 16 maintained in contact with the flexible outer skin 15 by a rigid internal support 12 of turret form braced by a tubular framework 13, the envelopes 16 being circular and/or of elongated form or of T- or X-shape. The skin 15 is secured to the support 12 by buttons or rivets 32. Instead of a relatively smooth skin, the skin may be of inflatable multi-tubular form so as to provide corrugations on the inside of the concrete, the skin being laid over an inflatable envelope of the form shown in Figs. 1, 2. Where hollows are required in the concrete shell a flexible sheet 2, Fig. 11, is secured over the inflated envelope 1 and elongated inflated elements 21 are laid over the sheet 2 and over wire netting 8 thereon. Further wire netting 22 is laid over the elements 21 and the concrete then applied. On setting the elements 21 are deflated and withdrawn. The elements 21 may be placed in position after a first coating of concrete has been allowed to set upon the core. Specification 554,954 is referred to.

Title: Improvements in or relating to variable-speed electric driving devices for surgical tools
IPC: A61B17/16
Filed: 1955-05-12
Abstract: 772,210. Dental engines. HAINAULT, M. May 12, 1955 [Oct. 20, 1954], No. 13794/55. Class 81(2) [Also in Group XXIV] A device for driving a surgical drill or saw, &c., comprises a sealed housing, containing an electric motor C and gearing providing direct drive and two step-down ratios, whereby the whole apparatus may be externally sterilized. The ratios are selected by sliding a rod H carrying a fork G which engages an axially slidable hub 5 on a driven shaft F. In the uppermost position of the hub 5. a set of dogs 6 on the shaft 3 of the motor C is engaged by dogs 7 on the end of the hub. Direct drive is then transmitted through a slot 15 in the hub and a pin L to the driven shaft F. and through a pin 14 and slot 13 to an output connector 18. When the hub 5 is moved to a central position, the dogs 6, 7 disengage and the hub is driven at a reduced ratio from a pinion D on the motor spindle through gears E, E 1  on a layshaft and a pinion K engaging the latter. The hub continues to drive the output shaft through the pin L, &c. In the lowermost position of the hub 5 it is free on the shaft F, since the pin L passes into a continuous recess R, and it is still driven through gears D, E, E 1 , K. However, a pinion O formed on the lower end of the hub 5 now engages the planet pinions M of a planetary gear assembly having a fixed annulus N. The planet carrier P is simultaneously pressed downwards by the hub 5 to engage dogs 9 thereon with dogs 10 mounted on the driven shaft F to give a still further reduced ratio.

Abstract: 1,186,381. Dynamo-electric machines. COMPAGNIE ELECTRO-MECHANIQUE. 23 March, 1967 [28 March, 1966], No. 13832/67. Heading H2A. [Also in Division F2] The rotor of a dynamo-electric machine is supported in the stator by gas pressure which acts as a gas bearing. As shown in Fig. 2, gas is fed into the air-gap 3 through radial passages 5 in the stator core, and leaves at the gap ends and through rotor ducts 8. As shown in Fig. 3, the stator bore may be improved by the use of a non-magnetic sleeve 13. Moreover, the gas may be used to cool the stator at ducts 14, and it may pass round the stator conductors in their slots (Fig. 4, not shown). As shown in Fig. 5, gas from stator duct 16C may pass into ducts 19 through which the rotor bars pass, these being located by lateral ribs 22 (Fig. 6, not shown). The spent gas escapes through radial holes 20 or axial holes 20a. If desired, the sleeve may be separated from the stator by a narrow air-gap, sealed where necessary by circumferential gaskets (Fig. 7, not shown). The same principle may be used to provide axial location of the rotor (Fig. 8, not shown).

Filed: 1971-05-07
Abstract: 1386235 Colour television RCA CORPORATION 4 May 1972 [7 May 1971] 13857/71 Heading H4F The B - Y demodulator 30 of a PAL colour television receiver is fed with reference oscillations of B - Y phase during each line period, and R-Y phase during each line blanking period. Any output from demodulator 30 during occurrence of the colour bursts is gated at 61 and used to control the phase of reference oscillator 65, in phase operation producing no output due to demodulation of the burst component at - (B - Y) phase by a reference signal at (R - Y) phase. The R-Y demodulator 40 is fed with reference oscillations of (R-Y) phase on alternate lines, and the output during occurrence of the colour bursts is gated at 71 and controls bandpass amplifier 19 via automatic chroma control amplifier 73. Absence of an output of sufficient amplitude from 71 operates colour killer 77 to cut off amplifier 19 and also resets PAL switch 69 in case this in due to reception of a colour signal but incorrect switching of switch 69. Colour killer 77 also causes cut-off of a sub-carrier trap in the luninance channel when it cuts-off amplifier 19. Colour killer 77 is rendered inoperative during each blanking period to allow recovery of the circuit if a colour signal is present.

Abstract: 345,548. Pneumatic springs and shock-absorbers. CALDWELL, C. W., 55, O'Reilly Road, Berea, Johannesburg, South Africa. May 6, 1930, No. 13937. [Class 108 (iii).] A vehicle suspension device comprises two pneumatic springs each consisting of a number of bellows units of differing crosssectional area and so connected that one spring expands while the other is compressed, one of the springs offering a greater resistance to compression than the other while a restricted airpassage connects the two. The springs 4, 5 are connected to one another and to the axle 3 by a centre bolt 9, the frame 2 of the vehicle being supported by brackets on the intermediate plate 6. Owing to their varying diameters the several bellows units in each spring yield in succession. The springs communicate with one another through the gap 10 between the central bolt 9 and the hole in the plate 6. When the load increases the volume of the lower spring 4 decreases at a greater rate than the volume of the upper spring 5 increases and the restricted orifice 10 limits the rate of movement. The effective volume of the bellows may be increased by connecting them to a reservoir 14 through a valve 16. Two such spring systems may be arranged at opposite ends of an axle and connected by pipes so as to equalize the loads.
