A speed governor comprises a rotating tube 10, Figs. 1 and 2, having a longitudinal split 13, a passage 16 for the flow of fluid and a nozzle in the passage so arranged that as the tube flexes outwardly with increasing speed of rotation, the flow of fluid through the passage is reduced. The free end of the tube has an integral position 11 joined to the split portion by a neck 12. In a modification, two blades at opposite sides of the split control the flow through a passageway parallel to the tube axis. Figs 5 and 6 show a third construction in which a tube 21 is connected by arms 23 to the sides of the split 13 so that it becomes misaligned with a tube 22 as the speed increases. The governor may be used to control a gas turbine.

To measure electrical energy, from the voltage signal U (Fig. 4) a first pulse signal is derived on lead 1, the product of the frequency f u  and pulse width # u  of which is proportional to the voltage and from the current signal I a second pulse signal is derived on lead 2, the product of the pulse frequency f i  and pulse width # i  of which is proportional to the current, these signals being gated in an AND gate 4 by a scanning pulse signal of frequency f s  and small pulse width # s  to a reversible counter 31 via a switch 24 the position of which depends on the polarity of the product U.I. Either the frequencies may be constant or, as in the embodiment described the pulse width may be constant. In a multiphase network the power of each phase may be converted separately into a proportional frequency and fed via OR gates 33, 36 to the counter. The same scanning frequency, phase delayed by members 42, 43, may be used for each phase measurement.

In a silk screen printing machine for multicolour decoration of frusto-conical articles A such as bottles, goblets and tumblers, each article is mounted in a rotatable work-holder 7 carried by an endless conveyer 6 below a series of stationary screens 8a, &c., with each of which the articles are brought into rolling contact, ink being pressed through the screens by squeegees 9a &c., which reciprocate at such a speed as to follow the line of contact between an article and a screen as it travels across the screen. Each article is held between a cap (30), Fig. 5 (not shown), which is pivotable between a loading and unloading position and an operative position, and a face plate (32) which is continually rotated by a pinion (38) fixed thereto and engaging a rack (39) extending the length of the chassis 3 on which the conveyer is mounted. The diameter of the pinion is made equal to the mean diameter of the article to be decorated, in order to register the impressions. The drive for the squeegees and for the conveyer is derived from a single motor (21), Fig. 1 (not shown), acting through a gear-box (24), the squeegee being reciprocated by a carriage (71), Figs. 5, 6 (not shown), having a cam follower (70) which engages a cam groove (67a) in a rotating drum (67), one revolution of the drum corresponding to one reciprocation of the squeegee. Different sizes and shapes of articles can be accommodated. The chassis 3 can be tilted about an axis 4 by screws 5 to angles dependent on the taper of the articles, the silk screens and squeegees can be raised and lowered, and the pinions exchanged to accommodate articles of different mean diameter, and the distance between the cap and face plate of each working head can be varied to fit articles of different lengths. The screens can also be moved longitudinally or transversely, with respect to the travel of the conveyer. Each screen may consist of a fine wire gauze whose meshes are blanked off except for a region corresponding to the design to be printed. In modifications, the squeegee may be temporarily fixed to the conveyer belt when the work head reaches the squeegee and each decoration section could include a plurality of squeegees.

[Also in Division F2] A winch mounted on a frame for movement along an overhead gantry comprises a rope drum 13 housing and driven through an epicyclic gear, the latter being driven by a motor mounted on one of a pair of end plates 15 between which the drum is journalled, the end plates being supported by the frame such that one support point takes the weight of the drum and motor assembly, and a further two support points share the rope load on the drum. The end plates 15 are connected by a tube 19 which centrally mounts an eye 22 supported on a rod (23), Fig. 1 (not shown), fixed to the frame, this providing the said one support from which the drum and motor assembly depends. The other two support points comprise trunnions 24 on the plates 15 angularly spaced with regard to the axis of the drum from the tube 19, and engageable with sockets on the frame, the trunnions being in line with the rope leaving the drum surface. The drum 13 comprises two sections 29, 30 incorporating grooves for symmetrically guiding two rope falls between which the load is supported, the two sections being divided by an internally toothed annulus 35 through which the drum is driven. This annulus meshes with elongated planet pinions 42, the end sections 42A and 42C of which mesh with annuli 44 fixed stationarily relative to the drum, and one end section 42A also meshes with a sunwheel 45 carrying planet wheels 56 driven from the winch motor through an annulus 52.

If the hologram covers a wide angle, a broad band filter, e. g. covering 250 A, may be placed between source 11 and hologram 10. The diffraction grating 15 may be a reflection or transmission grating and may be blazed. It may be formed from a pile of thin non-blazed replica transmission gratings.
