Title: Improvements in or relating to photographic cameras having coupled exposure meters
IPC: G03B7/00
Filed: 1957-10-31
Abstract: 867,998. Photographic cameras. GAUTHIER G. m. b. H. A. Oct. 31, 1957 [Feb. 5, 1957], No. 34038/57. Class 98(1) In a camera, the diaphragm aperture and shutter speed setting members control the indicating or follower member of an exposure meter by means of two separately rotatable rings or part rings, the first of which, on rotation, carries the second axially along the axis of rotation and the second has an edge cam track for operating the exposure meter member. Preferably, the rings are rotatable on the shutter casing of a camera objective and are connected directly to the diaphragm aperture and shutter speed adjusting rings. One ring may be journalled in a channel formed in the outer surface of the other one, as shown, both may be journalled on the shutter housing 1 and have pins 14 and 15 riding respectively in groove 3b of shutter speed adjusting ring 3 and between forked arms 16 of diaphragm aperture adjusting ring 2. The first ring 7 is moved axially by pin 12 thereon engaging slot 1d in housing 1. Alternatively, the first ring may be moved by a multiple screw-threaded connection with the housing. The first ring 7 is rotatably connected to the second 8 by a locking spring 11. Ring 8 is thus separately adjustable by means of ring 2 and rod 23 which control the indicating or follower member of the exposure meter rides on cam track 8c thereof. The adjusting rings 2, 3 are coupled together on releasing projection 22 and the shutter speed and diaphragm aperture can only then be adjusted by compensating amounts so that the total exposure value remains constant and rod 23 is not displaced. However the coupling arrangement between rings 2 and 3 is optional and when no coupling is provided the camera can have any type of diaphragm and shutter speed scales. Other variation in which for example rod 23 is non-resiliently held against track 8c and in which rings 7 and 8 are resiliently pressed together are referred to. Instead of groove 3b and forked arms 16, the movement of the adjusting rings 2 and 3 may be transmitted to the rings 7 and 8 by toothed pinions rotating on fixed spindles. In another arrangement, rod 23 may provide an abutment to limit the adjustment of rings 2 and 3, the rod being positioned by means of an exposure meter operated feeler lever system as disclosed in Specification 802,020.

Title: Improvements in or relating to straight bar knitting machines
Inventor: BLOOD RAYMOND
IPC: D04B15/64
Filed: 1958-10-24
Abstract: 936,179. Knitting-machines. WILLIAM COTTON Ltd. Oct. 19, 1959 [Oct. 4, 1958], No. 34040/58. Class 74 (2). A straight bar machine has an electric heating element 9h secured to a rod 6 which is freely mounted for endwise displacement, when required, to move the element into any of a plurality of positions along the needle row whereat it can engage yarn to be severed and, after being energized, can thereat sever the yarn The element engages the yarn extending from a pressed-off blank to the needles, to deflect it into a line perpendicular to the needle row and down between the sinkers ; and it is energized after a new ribbed top has been topped on and the yarn carrier has fed its yarn to a sufficient number of needles for it to be locked to them by advancing sinkers. The circuit is controlled by two switches in series. The first of these switches is constituted by a strip 9c which makes contact with the template rail 8 only when the rod 6 is rotated to turn the element down into the final position; closure of this switch prepares the circuit. Thereafter, when a rod 67 is moved in the direction A, to initiate topping-on, a cone 67a thereon rocks a lover 64 to stress a spring 65, which thereupon tends to displace a prop 61 from under the tail of a truck lever 55. This displacement is resisted by the pressure between prop and truck lever, until a high part of a cam 59 on the main cam-shaft 60 comes under the truck 56, whereupon the prop is released and the truck follows the cam. As the truck reaches a low point on the cam, an abutment 55b on the truck lever closes a switch 53 and the yarn is severed. When the rod 67 is is restored to its initial position, the mechanism regains its initial configuration. There may be one or more elements in each knitting section of a machine, all on a common rod. Specifications 813,435 and 832,751 are referred to.

Abstract: 944,120. Elevated and rope railways. UDYLITE RESEARCH CORPORATION. Sept. 10, 1962 [Sept. 11, 1961], No. 34582/62. Heading B7L. A closed circuit conveyer comprises a number of separable transfer sections 20, releasably secured to transfer relevating sections 22, and a power section 24. Tracks 42 on the upper side of the transfer sections 20 (Fig. 4) line up with tracks 56 on the elevating section 22 when in its lower position and with tracks 42 on the power section 24 (Fig. 5) so that work carriers 26 carrying work racks 36 may be advanced in step-by-step motion by a series of pushers 100 pivotally attached to a T-bar 86 movable longitudinally by the ram 90 disposed in the power section 24. Elevation of the carriers 26 so that the racks 36 clear the tank separating partitions 32 is effected by raising the tracks 56 with the carriers thereon. Such raising is effected by the ram 76, also in the power section 24, which reciprocates a T-bar 62 placed either below the T-bar 86 or by the side of it, the T- bar 62 having secured to it one end of a chain 58 which passes over the lower fixed idler sprocket 72 and the upper one 74 downwardly to the lift section where it is secured at 70. Whilst in the raised position the carriers 26 are advanced by auxiliary pushers 112 (Figs. 3 and 4) connected to an endless chain 100 which is driven from a sprocket 114 in splined engagement with a vertical drive shaft 116 having at its lower end a gear pinion 120 meshing with a rack 122 secured to the side of the T-bar 86. The lift section 24 may comprise a short length of fixed track elevated above the transfer track and two separate lengths of vertically movable track at each end of the fixed section to carry the work carriers 26 up to and down from the elevated section. In such an arrangement the work carriers may be advanced by a pivoted extensible lever attached by a link to the T-bar 62 at its lower end and directly to the pusher bar at its upper end.

Abstract: 1408507 Seismic energy generators ATLANTIC RICHFIELD CO 20 July 1973 [6 Sept 1972] 34641/73 Heading H4D A seismic energy generator comprises a first tube 20 closed at its ends, a piston 42 carried by a piston-rod 44 having a passage 54 for exhausting combustion gases, a second tube 48 mounted on the piston co-axially with the first tube and defining with the end closure member 24 of the first tube a combustion chamber 36, and a tube 66 for introducing gaseous fuel into chamber 36. When used on firm ground the generator is suspended (Fig. 1, not shown) by its piston rod 44 on a vehicle such that, in a precombustion position, tube 20 is held clear of the ground by gas pressure in chamber 35 above the piston. On firing the generator, tube 20 is accelerated downwards to impact the ground. The resulting recoil of piston-rod 44 is accommodated by the suspension system which includes a "catching" device to arrest the subsequent fall of the generator and so avoid a disturbing secondary impact. Exhaust gases are vented via restricted openings 60, 56. The gas in chamber 35 serves to brake the upward motion of the piston. When used on marshy ground the generator is fired from a partially submerged location. Details of constituent materials for the generator are given.

Title: Method and means for adjusting the water content of concretes or mixtures of granular materials
IPC: B28C7/00
Filed: 1933-12-09
Abstract: 429,942. Treating mould materials. GLANVILLE, W. H., Building Research Station, Garston, near Watford, Hertfordshire. Dec. 9, 1933, No. 34670. [Class 83 (i)] [See also Groups V and XIII] A method of producing sand or other granular material of a known water or other liquid content, e.g. for use in the preparation of concrete or mortar, and in foundry moulding consists in flooding the material with liquid in a porous container, allowing it to drain with or without mechanical disturbance, and subsequently adding a known quantity of liquid. The invention is based on the experimental fact that when sand is flooded in a porous vessel and allowed to drain, the amount of water after a certain time reaches a value which is approximately constant for any given kind of sand. This value can be altered by subjecting the vessel to mechanical disturbance. Apparatus suitable for carrying out the invention comprises, as shown, a container 1, having a perforated bottom 6, supported on a plate 4 which is mounted between springs 13, 14 on four vertical rods 10 so that it can move up and down. Mounted on bearings on the underside of the plate is a shaft 20 on which are two discs 21 provided with unbalanced weights 22. The shaft is driven by suitable power through a flexible coupling 23. The amplitude of the vibration can be adjusted by angularly adjusting one of the discs. A suitable spraying device 24 is arranged above the container.

Abstract: 1506607 Measuring direct current SIEMENS A G 21 Aug 1975 [4 Sept 1974] 34831/75 Heading G1U A direct current measuring system of the type in which a reference direct current is progressively varied until it balances the current to be measured is characterized in that the two currents are compared by applying the current il to be measured to the primary winding W 1, Fig. 1, and the reference current i3 to the secondary winding W2, of a transformer, by also applying a cyclically varying switching current i2 to the secondary winding so that the transformer core is repeatedly driven around its hysteresis loop (preferably square and narrow), and by detecting the voltage pulses y that appear across the secondary winding when the transformer core changes its state of magnetic saturation, these pulses occurring at times within the cycles of the switching current that depend upon the difference between the magnetic fluxes produced by the reference current and the current to be measured, and being used to gate out M a voltage z proportional to the value x of the switching current i2 at the instants they occur, which voltages z are used to control the reference current i3 generator RG so that the reference current i3 is varied towards a state of balance. The reference current may then be measured, MA. As described the gate M is constituted by a multiplier which multiplies the voltage pulses y which alternate in polarity but all of which have the same amplitude - by a voltage x across a resistor R1 in the switching current circuit, and since the voltage pulses y are of alternate polarity a switch S synchronized with the switching current generator is provided so that the emerging pulses - whose amplitudes represent the required difference - are all of the same polarity.

Abstract: 1,046,160. Winding webs. B. KAMPF, E. KAMPF, and H. KAMPF, [trading as ERWIN KAMPF MASCHINENFABRIK]. Aug. 16, 1965, No. 34988/65. Heading B6B. [Also in Division D1] Apparatus for winding a web of fabric which has been cut longitudinally and thereby divided into a plurality of narrow bands, comprises a plurality of winding sleeves 3 on which the bands are wound and adapted frictionally to be coupled to a rotatable shaft 2 and at least one friction coupling device for each sleeve 3, to couple the sleeve 3 to the shaft 2, whereby rotational motion may be imparted thereto, each friction coupling device including a cylindrical housing 8 mounted to and within one end of the sleeve 3, first friction means 7 keyed to the housing 8, second friction means 6 keyed to the shaft 2 and both contained within the housing 8 and being capable of axial movement relative to the housing 8 and means whereby means 6, 7 may be moved into and out of frictional engagement with each other. As shown, a friction coupling device is provided at each end of each sleeve 3 having flanged discs 10 connected thereto. The means 6, 7 comprise a plurality of nose rings engaging, respectively, in a groove 20 in the shaft 2 and in a groove 14 in the associated housing 8. Annular friction lining discs 9, e.g. of felt or plastics material, are provided between the rings 6, 7. Spacer rings (not shown) mounted to slide axially on the shaft 2 occupy the gaps between adjoining housings 8. The spacer rings and the housings 8 together form a block which at one end is bounded by an adjusting ring (not shown) detachably connected to the shaft 2 to prevent unintentional sliding of the block thereon and at the other end by a pressure member (also not shown). When axial pressure, selected to obtain sufficiently firmly wound rolls 1, is applied by the pressure member to the adjacent housing 8 towards the adjusting ring, this pressure is applied to the entire block so that each friction drive, i.e. the rings 6, 7, 9 and the housings 8, is compressed and rotation of the shaft 2 causes rotation of the sleeves 3. Since each housing 8 is coupled independently by friction to the shaft 2, each sleeve 3 can slip frictionally independently on the shaft. A circlip 15 projects into a channel 16 in a large outer nose ring 6 in each housing 8 to retain the rings 6, 7, 9 in the housing 8.
